Machine for resistance welding of continuously moving nets

专利摘要:
The invention relates to the field of welding and can be used in the manufacture of equipment for welding continuously moving nets. The aim of the invention is to provide a reduction in energy consumption and dynamic forces. Both crossheads 3 and 4 move together with the continuously moving welded product. At the same time, the yoke 4 and with it the upper electrodes 2 due to the downward movement of the push yoke 10 moves to the product. When the electrodes 2 come into contact with the nodes to be welded, the electrodes stop. However, yoke 4 continues to move down. In this case, the pressure yoke 10 continues to move downward, the lever 27 pivots about its axis, and the springs 28 create the necessary pressure. The working and reverse movement of the electrode cross member is controlled by a cam mechanism. 3 il. § CO s: about 05 oh fig 1

The invention relates to welding and can be used in the manufacture of equipment for welding continuously moving nets.
The purpose of the invention is to reduce the energy consumption of the drive and the dynamic forces.
Fig. 1 schematically shows a welding machine for continuously moving x-nets, a longitudinal section; Fig.2 is the same 5-front view; FIG. 3 shows an embodiment of the current supply of welding electrodes.
The wire feed plane for the fabricated grid and the finished grid is indicated in FIGS. 1-3 with letters xx. A row of electrodes 1 and 2 are located below this path of supply and above it, fixed at intervals along the electrode traverse 3 and 4 that run across the entire width of the machine and isolated with respect to them. The lower electrodes 1 are connected in pairs through conductive tapes 5 and 6 to the secondary circuits of the transformers. The upper electrodes 2, through conductive tapes 7, connect to the machine passing across the entire width; traversing 8 of a highly conductive material, mainly copper, which forms a common passive current jumper for all the upper electrodes.
The two pressure arms 9 and 10 also run across the entire width of the machine. These arms are made very powerful in order to be able to perceive all the pressure forces that are applied to the material being welded to the material being welded
The clamping bar 10 at both its ends is respectively pivotally attached to the single-arm lever 11 which, with the help of the adjusting axis 12, is installed with the possibility of rotation in the wall of the housing
The shaft 13, fixed at both ends rotatably in the machine body, bears on itself two fixedly single shoulder arms 14. The axes of the shaft 13 are parallel to axis 12. The lever 14 is equal in length to the lever 1 1 and is also hingedly connected to the pressure beam 10, therefore the levers 11 and 14 form a hinged four-door link for moving the pushing bar 10. The single-arm lever 15 is fixedly connected to the shaft 13. The lever 15 is actuated 1607 .2
vat driven from the eccentric 16 connecting rod 17.
The traverse clamp 9 may be stationary in the machine body,
5, however, it is predominantly mounted movably similarly to a pushing bar 10. For this purpose, it is hinged at each end to two single-arm levers 18 and 19, which form a hinged four-bar bearing, while the lever 19 is fixedly connected to the shaft 20 installed with a possibility in the machine body whereas the lever is 18 set15
flax with the possibility of rotation directly
in the case of the machine. A single-arm lever 21, which is fixedly connected to the shaft 20, allows, through a hand-driven lead screw 22 0, a permutation of the pressure train 9 in height. This makes it possible to constantly adjust the pressure beam 9, regardless of electrode wear and regardless of the thickness of the wire assemblies in accordance with the diameter of the wires to be welded, always ensures satisfactory contact of the electrodes with the welded material.
The lower electrode beam 3 is pivotally connected to the push rods 23, which are pivotally connected both to this electrode beam 5 and to the bracket 24 fixed on the pressure beam 9, and therefore they are swinging supports supported on the pressure beam 9. the rods 0 23 are connected by an electrode to the yoke 3 and a push yoke 9 with each other, so that the electrode yoke 3 can move relative to the pushing yoke 9 only in one direction, which is parallel to the plane of xx feeds and wire.
In order for the bending loads on the electrode beam 3 to be as small as possible, the push rods 23 0 are located along the electrode beam 3 at regular intervals. Accordingly, each third electrode 1 is supported on the push rod 9 by means of the push rod 23, due to 55 of this, the forces arising from the movement of the electrode traverse 3 are reduced as much as possible, and thus the drive power is saved.
At the upper electrode beam 4, the force is transferred so that only individual electrodes 2 are pressed against the material to be welded when the pressure beam is lowered due to the individually prestressed spring-loaded pushers slidable in the electrode beam. However, the type of force transmission shown in Figures 1 and 2 is advantageously chosen. At the same time, each electrode 2 is guided with the help of the guide rod 25 with the possibility of sliding in the electrode cross member 4. For each guideline} 5 follow the cam 45 set by it

can be changed with the adjusting screw 29. The stop 30 limits the ability to move the two shoulders. With this design, the pressure of the pressure rod 30 is pressed directly to the individual electrodes. Therefore, the electrode cross bar remains completely unloaded and serves only to guide the electrodes as they move, parallel-35 is connected to the grid supply path intended for the respective paths.
At both ends of the electrode crossheads 3, 4 are located on one end disk 31, 32. Peripheral

The other points of the end plates 31 and 32 are hingedly connected to their respective leads, which are fixedly connected to the shaft 37, 38 that are rotatably mounted in the housing wall of the machine. Each shaft 37 and 38 are connected to one of the gear segments 39 and 40. Both toothed gear segments are with each other
the other and thus cause the simultaneous movement of both electrode crossbars 3 and 4 in the direction of the arrow P in Fig. 1 parallel to the xx plane of the wire feed.
The toothed segment 40 is pivotally connected to one end of the connecting rod 41, the other end of which is pivotally connected to one of two parallel single-arm levers 42, which are fixedly connected to the shaft 43. One of the levers .42 carries the cam reading roller 44. The common shaft 43 forces both levers 42
through the reading roller 44 movement. The compression spring 46 loads the levers 42 in the direction of the cam 45. In FIG. 1, the cam 45 for simplicity of the image

to rotate, the crank 17 begins to move upwards and turns the one-arm lever 15 counterclockwise, thereby pushing the yoke 10 moves downwards. This movement is transmitted through the leads 33 (Fig. 2) to the electrode yoke 4 and at the same time through the push rods 26 to the electrodes 2.
Simultaneously with this movement, the cushion 5-5 of the pawl 45 begins to accelerate the reading roller 44 in the direction of movement of the welded mesh (arrow P). This motion is transmitted through a connection5 .13
on the toothed segment TO, through the shaft 38 to the leash 36, to the end disk 32 and the upper electrode yoke 4, and through the toothed segment 39, shaft 37, the leash 35 and the end disk 31 to the lower electrode yoke 3. Therefore, both electrode crossbars 3 and 4 begin to move together with the continuously moving welded mesh and carry them along. In this motion, electrodes 1 and 2.
At the same time, the upper electrode beam 4 and with it the upper; The electrodes 2 due to the downward movement of the push rod 10 move to the material being welded from above.
The cam 45 is shaped so that the electrode crossheads 3 and 4 shortly before the upper electrodes 2 touch the material being welded, reach the same speed as the continuously fed material being welded and, starting from this moment, move Continuously at a constant speed. As soon as the upper electrodes 2 touch the nodes to be welded, they end their movement in the vertical direction, their guide rods 25 begin to slide in moving further down the electrode cross-pieces 4. Since the pressure of the cross-bar 10 continues its downward movement, the two shoulders 27 turn around them installation axes in the clockwise direction, with the compression springs 28 creating the required welding pressure.
The welding current can now be turned on. After passing the top dead center of the eccentric 16, the movement of the pressure beam 10 occurs in the opposite direction, the pressure beam 10 and with it the electrode beam 4 begins to move upwards. However, the upper electrodes 2 and further remain on the material to be welded until the compression springs 28 are unloaded so that the two arms 20 at the expense of the stop 30 create an obstacle for further counterclockwise rotation.
After the eccentric 16 passes the top dead center, the welding current is turned off. While the compression springs 28 are still compressed, the electrodes 1 and 2 compress the already welded wires together.

Once the electrodes 2 are removed from the material being welded, the cam
45 releases the reading roller 44, after which the compression springs 46 are unloaded and at the same time return to the initial position the electrode crossheads 3 and 4.
A cam may also be provided with a guide groove in which the reader roller enters, and both the working and return movements of the electrode crossheads are controlled.

produced with intermediate activation of a corresponding downward transmission from the main drive shaft of the welding machine. However, in this case, it is possible to weld only gratings with a completely defined, structurally defined mutual distance between the rows of welding points.
If gratings are to be welded, in which the mutual distances between
a number of welding points have an arbitrary selectable value, then a one-turn clutch must be engaged between the main drive shaft of the welding machine and the shaft 47. When turned on
This clutch cam 45 begins to rotate. After welding a series of wire assemblies and returning the traverse bars 3 and 4 and the pressure beam 10 to the initial position, the coupling connection between the main drive shaft of the machine and the shaft 47 is automatically interrupted again.
The material being welded at a uniform speed now passes a certain part of the way until the next series is located; they are on the same axis of the wire nodes that fall into the welding zone and the single-turn coupling is switched on again by the control ele- ments.
It is possible to provide a separate drive for the camshaft 47. For this, a hydraulic motor can be used, which can be controlled electronically using electro-hydraulic valves.

from the central control unit.
In addition to the actuators described, other actuators can also be used, such as, for example, two hydraulic operating cylinders adjustable by means of electro-hydraulic servo valves, one for driving the electrode crosshead and the other for driving the clamping crosshead.
