    Technical field
    [0001] This disclosure relates to apparatus and processes related to forging and forging presses. Prior art
    [0002] Forging presses can form parts with a progressive set of forging tools, such as dies and punches. The parts that start as metal billets move from the forming station to the forming station in order, changing sequentially in shape. The forged component that emerges from the final station can be further processed, for example, by machining or grinding. The number of parts formed at each station is directly dependent on the frequency with which the forging press can complete a cycle to forge a workpiece (eg, receive a workpiece in a die, shape the workpiece, and extract the die workpiece). summary

    [0030] With reference to figure 1, a portion of a forging press 100 according to the present disclosure is shown including an anvil 102 and a press hammer 104 that can move reciprocally with respect to anvil 102, which can be clamped to a press housing 106. Induction heater feeder assemblies 108, 110 can receive parts in the form of metal billets, and supply parts for an induction heater assembly 111, which can include induction heaters 112, 114. The assembly induction heater 111 can be attached to the housing.
    [0031] With heating by the induction heaters 112, 114, the parts can be provided for a matrix feeder 118. As further described here, the feeder 118 can move the parts to the matrices of the first two stations 122, 124. The feeder 118 can also deflect parts that do not reach sufficient temperatures or rise to undesirably high temperatures for classifiers 126.
    [0032] Since the first station dies 122, 124 are supplied with parts, the press hammer 104 can descend on the anvil 102. As shown in figure 2, forming pins 130, 132 can be positioned above the dies of first station 122, 124. When the press hammer 103 descends, the forming pins 130, 132 can apply pressure to the heated part, can deform the parts, and can force the parts to take the shape of the mold formed by the first station dies 122, 124.
    [0033] With reference to figures 4 and 5, the induction heater feeder 108 may have a tray 400 that receives parts. An actuator 402 may have an arm 404 that can move the parts into a position where another actuator 406 can move the part towards another tray 408 that, for example, can power the induction heater 112. The second heater feeder induction 110 can be a spectral image of feeder 108.
    [0034] With reference to figures 6 and 7, the induction heater assembly 111 may have two induction heaters 112, 114. Each induction heater 112, 114 may have an inlet end 600 and a discharge end of part 602. At the inlet end 600, the induction heaters 112, 114 can have an inlet opening 604 that can allow parts to enter the induction heater housing 606. The heater housings 606 may contain induction heater coils and a pyrometer to measure the temperature of the parts. According to an aspect of the present teachings, the pyrometer can be positioned inside the housing 606 and adjacent to the discharge end 602. The induction heater assembly 111 is attached to the housing 106 with supports 608. In the forging press 100 shown in figure 1 , each of the two induction heaters 112, 114 can have parts fed into their inlet opening 604 by one of the feeders 108, 110. The parts can exit the induction heaters 112, 114 serially through outlet openings 610.
    [0035] With reference to figures 8, 9 and 10, a matrix feeder 118 can have an actuator 800 that can move the arm 802 between the discharge end of part 602 of the induction heaters 112, 114 and the first station dies 122. Ramps 804 can be positioned to receive heated parts from induction heaters 112, 114. Parts can fall into receptacles 806 and can be supported from below by trays 808. Actuator 800 can move arm 802 to such a position that the receptacles 806 can be on the first station dies 122, at which point the pieces have traveled beyond the edges 810, and therefore are no longer supported below by trays 808 and fall into the first station dies 122. A portion 814 of each of the trays 808 can also be extracted by one of the actuators of tray 812. These portions of tray 814 are positioned below receptacle 806 when receptacle 806 is below the discharge end of part 602 in position to receive a piece from one of the induction heaters 112, 114. When a tray 812 actuator extracts a portion of tray 814, the piece may fall out of receptacle 806 and into classifier 126. According to a aspect of the present teachings, the tray actuator 812 can extract a portion of tray 814 depending on the temperature measured by a pyrometer. Such a pyrometer can be housed within housing 606 adjacent to the discharge end 602 of induction heaters 112, 114. For example, tray actuator 812 can extract tray portion 814 when the part supported by tray 808 has not reached sufficient temperature or rise to undesirably high temperatures. Such parts can be downloaded to a classifier 126 as further described here.
    [0036] With reference to figures 11, 12, and 13, the classifier 126 has a first end 1100 and a second end 1102. When mounted on the press 100, the first end 1100 of classifier 126 may be raised in relation to the second end 1102 This allows parts entering a chute 1104 at the first end 1100 to fall to the second end 1102.
    [0037] The chute 1104 has two openings 1106, 1108. An opening 1106 can be arranged at the second end 1102 of classifier 126. The other opening 1108 can be arranged closer to the discharge end 602 of the induction heaters 112, 114 under the which the classifier 12 6 can be mounted. The opening 1108 which can be configured to be closer to the discharge end 602 can be selectively closed by a door 1110 via an actuator 1112. The actuator 1112 can, for example, selectively open the door 1110 when an overheated part enters the rail 1104, which in turn can allow the workpiece to travel through opening 1108. When a heated piece enters trough 1104, actuator 1112 can close door 1110, forcing the heated piece to continue beyond door 1110 until opening 1108.
    [0038] With reference to figures 14, 15 and 16, a double unloader 136 may have arms 1400. Each arm 1400 may include two parallel rods 1402 separated by a constant distance from each other at each point from an inlet end 1404 to an outlet end 1406. A pivoting actuator 1408 can pivot an arm actuator 1410 on an axis 1412. A frame 1414 can hold the rods 1402. Both the frame 1414 and the rods 1402 can pivot together with the arm actuator 1310 The arm actuator 1410 can move the arms reciprocally in a direction parallel to the linear rods 1402.
    [0039] With reference to figure 17, a part 1700 conformed to the second station dies 125 are engine valves having a wide head 1702 that joins an axis 1704. Stems 1402 can suspend part 1700 by head 1702. This arrangement it can allow part 1700 to slide along rods 1402 when they are angled from a horizontal position.
    [0040] According to one aspect of the present teachings, when mounted on the forging press 100, the arm actuator 136 can move the arms 1400 towards the second forming stations 124 where the inlet end 1404 of the arms 1400 moves by under the valve head 1702 shown in figure 17. The pivot actuator 1408 can lift the part upwards, and it can also tilt the rods 1402 such that the inlet end 1404 can be above the outlet end 1406. Parts 1700 can slide along the rods 1402 towards the outlet end 1406, at which point the parts 1700 can slide off the rods 1402, for example into a container for further processing. The arm actuator 1410 can then retract the arms 1400 in advance to another cycle to form parts on valves at the second forming stations 124.
    [0041] With reference to figures 18, 19, 20 and 21, the press hammer 104 can include the guide sleeve 1800. The guide sleeve 1800 can fit over the guide pin 1802 as the press hammer 104 lowers over the anvil 102, ensuring the alignment of the press hammer 104 with the anvil 102. According to one aspect of the present teachings, first season dies 122 can be along line A. According to another aspect of the present teachings, the second station matrices 124 can be along line B. The progression of the pieces through the first station matrices 122 and second station matrices 124 can follow a line parallel to line P. A line passing through each first station matrix 122 and its corresponding second station matrix 124 can be parallel to line P. Line P can be perpendicular to both lines A and B.
    [0042] In accordance with still other aspects of the present teachings, three or more sets of first season arrays, for example the first season arrays 122 illustrated here, can be used to simultaneously form a plurality of parts having a particular shape. In another aspect of the present teachings, the plurality of first season dies have a common mold shape, such that the dies conform to a piece having a common shape. In yet another aspect of the present teachings, three or more sets of second season arrays, such as second season arrays 124 illustrated here, can be used to simultaneously form a plurality of pieces received from the plurality of first season arrays .
    [0043] The first station dies 122 can be positioned under the pin 130. During the operation of the press 100, the pin 130 can descend on parts deposited in the first station dies 122. The part is extruded into a particular shape complementary to the first station die 122. Once the part is extruded into the first station die 122 and the press hammer 104 rises from the anvil 102, the extraction arm 1804 can be pushed up against the parts and can make the rods 2000 dislodge the parts of the first station dies 122. The parts can be transferred from the first station dies 122 to the second station dies 124, for example with a robotic mechanism that grips the parts and moves them to the second station dies 124.
    [0044] The second station dies 124 can be positioned under the stroke pin 132. The stroke pin 132 can descend over the pieces that have been formed in the first station dies 122 and moved to the second station dies 124. A piece is shaped to its final forged shape, which is complementary to the shape of the second station die 124. Once the piece is forged and the press hammer 104 rises from the anvil 102, the extraction arm 1806 can be pushed upwards against the parts and make the rods 2100 dislodge the parts of the second station dies 124.
    [0045] Figure 22 illustrates a diagram of a 2200 method for forging parts according to an aspect of the present teachings. In block 2202, the parts can be fed to at least one induction heater. In one aspect of the present teachings, two induction heaters are used. In block 2204, parts can be heated by induction heaters. In block 2206, the temperature of the parts can be measured. Depending on whether the measured temperature is within an acceptable temperature range or not, the part can be unloaded as done in block 2208, for example by unloading the part on a chute for additional collection and processing, or it can be provided for the feeder. die 118 in block 2210. According to one aspect of the present teachings, a die feeder 118 such as the one described here having two piece receptacles 806 can be used to supply pieces simultaneously to a plurality of first season dies 122 having a shape common die, for example as done in block 2212. In block 2214, the parts in the first station dies can be formed simultaneously, as occurs when the forging press 100 shapes parts in the first station dies 122. In block 2216, the pieces formed in block 2212 can be provided for a plurality of second station dies having a common matrix format. In block 2216, parts formed on the second station dies can be removed from the second station dies. Such removal can be performed, for example, by the unloader 136.
    [0046] For the purposes of this disclosure and unless otherwise specified, "one" or "one" means "one or more". To the extent that the term "includes" or "including" is used in the specification or claims, it is intended to be inclusive in a manner similar to the term "comprising" how that term is interpreted when used as a transitional word in a claim. In addition, to the extent that the term "or" is used (eg, A or B) it is intended to mean "A or B or both". When depositors intend to indicate "only A or B but not both" then the term "only A or B but not both" will be used. Therefore, the use of the term "or" here is inclusive, not exclusive. See, Bryan A. Garner, A Dictionary of Modern Legal Usage 624 (2d. Ed. 1995). Also, to the extent that the terms "in" or "within" are used in the specification or in the claims, they are intended to additionally mean "about" or "in". As used here "about" will be understood by persons skilled in the art and will vary to some extent depending on the context in which it is used. If there are uses of the term that are not clear to people experienced in the art, given the context in which it is used, "about" will mean up to plus or minus 10% of the particular term. From A to B it is intended to mean from about A to B, where A and B are the specified values.
    [0047] Although the present disclosure illustrates several aspects of the present teachings, and although these aspects have been described in some detail, it is not the intention of the depositor to restrict or in any way limit the scope of the claimed invention to such detail. In light of the disclosure, additional advantages and modifications will be apparent to those skilled in the art. Therefore, the invention. in its broadest aspects, it is not limited to the specific details and illustrative examples shown and described. Consequently, deviations can be made from such details without deviating from the spirit or scope of the invention claimed by the depositor. In addition, the foregoing aspects of the present teachings are illustrative, and no single feature or element is essential for all possible combinations that can be claimed in this application or in a later one.
