    专利说明:

    [0001] The present invention relates to a device for processing metal bodies such as, for example, elongated metal bodies obtainable from bars.
    [0002] Devices for machining mechanical parts are known, consisting of a support frame for a rotary table that can rotate intermittently around a main axis of rotation and defining, at its periphery, a plurality of support seats for the respective metal bodies to be processed, which are fed to the rotary table by means of a feeding device.
    [0003] The support seats extend along a respective longitudinal axis, which extends substantially parallel to the rotation axis of the rotary table.
    [0004] The known devices also comprise a plurality of machining stations, each of which typically has a tool, arranged laterally with respect to the support seats in such a way as to be able to carry out in sequence a series of mechanical machining operations on the piece fed to the table rotating.
    [0005] Typically, these types of equipment provide, in order to perform the machining, that it is the piece to be machined that is rotated around the longitudinal axis of the support seat while the tool is possibly moved radially and longitudinally with respect to this axis .
    [0006] Each support seat is therefore operationally associated with a respective motor, which, in order to ensure the torque required for the work to be carried out, has such dimensions as to oblige the use of tables having a considerable size.
    [0007] Some solutions envisage the use of so-called electro-spindles, which integrate both the electric motor and the support seat in a single component.
    [0008] These solutions are extremely expensive and in any case are not capable of significantly reducing the overall dimensions.
    [0009] Furthermore, the current configuration of the devices described above provides that the tables lie on a substantially vertical plane.
    [0010] This implies that the tools must be arranged laterally with respect to the seats and this makes it difficult to perform some types of machining.
    [0011] It is also noted that in known solutions, the tables rotate around their own axis of rotation, in a first direction of rotation and also in a second direction of rotation for repositioning.
    [0012] This leads to an increase in the cycle time for each piece.
    [0013] The aim of the present invention is to solve the problems and to obviate the drawbacks described above, by providing an extremely reliable device for processing metal bodies.
    [0014] Within the scope of this aim, an object of the invention is to provide a device for processing metal bodies which allows to significantly increase productivity.
    [0015] Not least object of the present invention is to provide a device for processing metal bodies having a competitive production cost so as to make its use advantageous also from an economic point of view.
    [0016] This aim, as well as these and other objects which will become clearer hereinafter, are achieved by a device for processing metal bodies according to the provisions of claim 1.
    [0017] Further characteristics and advantages of the invention will become clearer from the description of some preferred but not exclusive embodiments of a device for processing metal bodies according to the invention, illustrated by way of non-limiting example in the accompanying drawings in which:<tb> <SEP> Figure 1 shows a perspective view of a device for processing metal bodies according to the invention;<tb> <SEP> Figure 2 is a side view of the device represented in Figure 1; figure 3 represents an enlarged scale view of a portion of the device of figure 2;<tb> <SEP> Figure 4 shows a side view of the rotary table of the device according to the invention;<tb> <SEP> figure 5 represents a section along the plane identified by the trace V-V of figure 4;<tb> <SEP> figure 6 represents a section along the plane identified by trace VI-VI in figure 4.
    [0018] In the following embodiment examples, individual characteristics, reported in relation to specific examples, can actually be interchanged with other different characteristics, existing in other embodiments.
    [0019] The present invention relates to a device, generally indicated with the reference number 1, for processing metal bodies.
    [0020] The device 1 comprises a support frame 2 for a table 3 which can rotate intermittently around a main axis of rotation 100.
    [0021] The table 3 defines a plurality of support areas 3a for at least one respective support seat 3b.
    [0022] Conveniently, the support areas 3a are defined at the periphery of the table 3.
    [0023] The support areas 3a are mutually angularly spaced around the main axis of rotation 100.
    [0024] Purely by way of example, the table 3 shown in the figures comprises eight support areas 3a, each of which has two respective support seats 3b.
    [0025] Conveniently, the support seats 3a comprise a so-called gripping mandrel.
    [0026] Each support seat 3b develops around a respective longitudinal axis (101a, 101b, etc.).
    [0027] Each support seat 3b is intended to support a respective metal body 4 to be machined, which is fed to the table 3 by means of at least one feeding device, not shown in the figures.
    [0028] The device 1 has a plurality of processing stations 30, which are designed to engage sequentially with the metal bodies 4 supported by the table 3.
    [0029] In particular, the processing stations 30 are angularly spaced from each other around the main axis of rotation 100 of the table 3 in a manner corresponding to the support areas 3a.
    [0030] Each support seat 3b is operatively connected to a motor 20, which is designed to rotate the metal body 4 about the longitudinal axis 101a, 101b, etc. of the respective support seat 3b. According to the present invention, the longitudinal axes 101a, 101b, etc. of the support seats 3b extend on a plane substantially perpendicular to the main axis of rotation 100 and are spaced from the development axis 102a, 102b, 102c, etc. the output shaft 21 of the respective motor 20.
    [0031] In particular, the development axes 102a, 102b, 102c, etc. the output shaft 21 of the motors 20 are substantially parallel and spaced from the plane defined by the table 3.
    [0032] Conveniently, the motor 20 comprises an electric motor.
    [0033] Advantageously, the main axis of rotation 100 develops along a substantially vertical direction and the longitudinal axes 101a, 101b, etc. they develop along a substantially horizontal direction.
    [0034] This constructive choice allows to obtain numerous advantages such as the ease of inspection and intervention at the support areas 3a and at the machining stations 30, a trajectory of falling shavings that does not interfere with other machining stations 30 and the possibility, as will be explained better below, to use in the machining stations 30, tools arranged, indifferently, frontally or laterally with respect to the support seat 3b.
    [0035] In this regard, the machining stations 30 have at least one tool 31b arranged laterally with respect to the support seat 3b.
    [0036] In addition or alternatively, the machining stations 30 can have at least one tool 3 la arranged in front of the support seat 3b.
    [0037] Going into more detail, the device 1 comprises motion transmission means 22 interposed between the support seats 3b and the respective motor 20.
    [0038] specifically, the transmission means 22 are interposed between the support seats 3b and the output shaft 21 of the motors 20.
    [0039] By way of example, such motion transmission means 22 comprise for example a toothed belt 22a or a pair of gears.
    [0040] Conveniently, the table 3 is rotatable around the main axis of rotation 100 in a single direction of rotation.
    [0041] This obviously entails a reduction in the time required to process each piece and consequently an increase in the productivity of the device 1.
    [0042] In this regard, it is possible to provide that the device 1 is provided with a drive motor 40 for moving the table 3 with respect to the frame 2 around the main axis of rotation 100.
    [0043] As already mentioned, according to a preferred embodiment shown in the figures, each support zone 3a has at least two support seats 3b.
    [0044] The support seats 3b of the same support zone 3a can for example be operationally connected to a single motor 20.
    [0045] However, nothing prevents the provision that the support seats 3b of the same support zone 3a are operatively connected to respective motors 20.
    [0046] In this case it is appropriate to provide that the motors 20 associated with support seats 3b in the same area have the development axis 102a, 102b, 102c, etc. the output shaft 21 at different heights to reduce the overall dimensions of the device 1.
    [0047] Advantageously, means for controlling the motors 20 are provided, which are designed to allow the locking of said motors 20 during engagement with the processing stations 30.
    [0048] In this case, the tools 31a, 31b of the machining stations 30 can be moved in rotation around the longitudinal axis 101a, 101b, etc. of the respective support seats 3b.
    [0049] The device 1 can be associated with two or more power supply devices.
    [0050] The operation of a device 1 according to the invention clearly follows from what has been described above.
    [0051] In particular, one or more feeding devices feed the metal bodies 4 to the table 3.
    [0052] It is possible to provide a continuous feeding of the pieces from bar, and in this case one of the machining stations 30 is intended for cutting mechanical pieces from the bar, or to carry out the cutting of mechanical pieces from a bar at a and then feeding the metal pieces to be machined to the table 3, and in particular to the support seats 3b.
    [0053] The table 3, by rotating around the main axis of rotation 100, carries the mechanical parts supported by the support seats 3b at the various processing stations 30.
    [0054] The motors 20, which are arranged with their output shaft 21 at a lower level than that of the table 3, rotate, thanks to the interposition of the motion transmission means 22, the support seats so as to allow the machining of the mechanical piece 4 by the respective machining stations 30.
    [0055] The positioning of the motors at a different height with respect to the plane of the table 3 allows to drastically reduce the dimensions of the table itself.
    [0056] All the characteristics of the invention, indicated above as advantageous, convenient or the like, can also be missing or be replaced by equivalents. The invention thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the inventive concept.
    [0057] In practice it has been found that in all the embodiments the invention has achieved the intended aim and objects.
    [0058] In practice, the dimensions may be any according to requirements.
    [0059] Furthermore, all the details can be replaced by other technically equivalent elements.
