Description

TECHNICAL FIELD

[0001] The application relates to the technical field of plate wire forming, and particularly relates to a plate wire continuous feeding equipment. BACKGROUND

[0002] Plate wire bending forming processing is commonly used in various industrial products, such as wiper connecting rod processing and forming. When the plate wire bending equipment is working, a feeding device needs to continuously provide the cut plate wire semi-finished product to the bending machine.

[0003] For example, the patent with the announcement number CN113385976B discloses a feeding mechanism of a wiper connecting rod, which comprises a support frame, a first lifting driving element, a first translation driving element, a stock bin and a material lifting fork. The support frame is provided with an opening window, the first lifting driving element is vertically fixed in the opening window, the material lifting fork is installed on the sliding table of the first lifting driving element, the top of the material lifting fork is provided with two fork heads, the first lifting driving element can drive the material lifting fork to stretch out of the opening window, and then the workpieces in the stock bin are lifted one by one. The first translation driving element is installed on one side of the support frame along the X-axis direction, a guide rail is installed on the other side of the support frame opposite to the first translation driving element, the guide rail is arranged in parallel with the first translation driving element, a moving plate is slidably installed on the guide rail and the first translation driving element, and the bottom of the moving plate is provided with an avoiding hole for avoiding the fork heads. The stock bin is arranged on the moving plate, and the first translation driving element can drive the moving plate to move along the X-axis direction to send the workpieces in the stock bin to the feeding work station. A plurality of vertical partition plates are arranged in the stock bin, the partition plates are installed along the Y-axis direction, the stock bin is divided into a plurality of sub-stock bins by the partition plates, and a column of workpieces is stacked in each sub-stock bin. The first translation driving element can drive the stock bin to move in the direction of the feeding work station at a fixed stroke, and each column of sub-stock bins is moved to the feeding work station one by one. The feeding mechanism further comprises a feeding clamping assembly for pushing the lifted workpieces in the sub-stock bin to the clamping mechanism.

[0004] Although the feeding mechanism realizes continuous operation, manual cooperation is still needed to intermittently store a stack of plate wires in the stock bin, and the automation degree is not high.

[0005] In order to improve the automation degree of plate wire feeding, if a transfer mechanism is directly arranged to transfer the cut plate wire to the bending machine, the end of the plate wire needs to be clamped and then pulled out of the cutting machine. Since the plate wire has an elongated structure, the part of the plate wire other than the clamping point at the front end is in a suspended state during the pulling and transferring process, and therefore the plate wire is prone to deflection, which leads to the fact that the plate wire cannot be accurately sent into the clamp of the bending machine, and the feeding precision and stability are reduced, and the consistency of the finished products after bending is poor.

[0031] The present application has the following advantages:

[0032] The present application realizes the continuous pipeline operation of cutting, moving and feeding the plate wire, and has higher operation efficiency and automation compared with the manual intermittent feeding.

[0033] The moving mechanism and the feeding mechanism cooperate to accurately feed the plate wire. In order to avoid the plate wire from being skewed during movement, the supporting plate is installed on the sliding table of the feeding mechanism to hold the plate wire, and the correction block extending along the X-axis is installed on the supporting plate. The three-axis module drives the finger cylinder to move close to the correction block, preventing the plate wire from being skewed. Meanwhile, the outer side wall of the correction block is provided with an X-direction dovetail groove, and the supporting plate of the three-axis module is provided with a slide rail matched with the X-direction dovetail groove. The slide rail can be slid into the dovetail groove, and then push the correction block to the direction of the clamping cylinder.

[0034] The supporting plate of the present application includes a bottom plate and a top plate. The Y-direction rack and pinion assembly is installed at the bottom of the bottom plate. When the Y-axis module pushes one of the correction blocks on the bottom plate, the Y-direction rack on the bottom plate drives the gear to rotate.

[0051] Example 1

[0052] like Figures 1 to 11 As shown, a continuous feeding device for sheet and wire is used to cut sheet and wire and feed them into a bending machine for bending. This feeding device includes: a cutting mechanism 1, a transfer mechanism 2, and a loading mechanism 3.

[0053] Please refer to Figure 1 The cutting mechanism 1 is used to cut the board wire to a fixed length and convey it horizontally to the transfer mechanism 2. The cutting mechanism 1 can use a cutting die 11 with a cutter. The board wire passes between the upper and lower dies, and then the dies are closed, causing the cutter to cut the board wire. The cutting mechanism 1 is equipped with a roller assembly 12, which includes rollers arranged vertically opposite each other. One of the rollers is driven to rotate by a motor. The board wire is clamped in the gap between the upper and lower rollers and conveyed towards the transfer mechanism 2 by the rotating roller. This type of cutting die 11 and roller assembly 12 are known technologies and will not be described in detail.

[0054] The transfer mechanism 2 is used to transfer the sheet wire 4 to the feeding mechanism 3. The cut sheet wire semi-finished product has a slender structure. The transfer mechanism 2 clamps the front end of the cut sheet wire 4. The clamping point of the feeding mechanism 3 on the sheet wire 4 is far away from both ends of the sheet wire, that is, the clamping point is close to the middle part of the sheet wire. In this way, the sheet wire can be fed into the fixture of the bending machine in a straight and stable manner.

[0055] For details, please refer to Figure 1 and Figure 2The transfer mechanism 2 comprises a three-axis module and a finger cylinder 24. The slider of the X-axis module 21 is provided with the Y-axis module 22, the output end of the Y-axis module 22 is provided with a vertical support plate 221, the support plate 221 is provided with the Z-axis module 23, and the output end of the Z-axis module 23 is provided with the finger cylinder 24. After the cutting mechanism 1 cuts the plate wire, the plate wire is transported to the direction of the finger cylinder 24. The two clamping heads 241 of the finger cylinder 24 can move towards each other in the XY plane to clamp the front end of the plate wire. At this time, the middle and rear end of the plate wire are still located in the cutting mechanism 1. Then, the X-axis module 21 drives the finger cylinder 24 to translate to the side of the feeding mechanism 3, and cooperates with the roller group to pull out the rear end of the plate wire from the cutting mechanism 1.

[0056] The Y-axis module 22 and the Z-axis module 23 of the embodiment can be selected from, but are not limited to, a cylinder.

[0057] Specifically, referring to Figure 1 The feeding mechanism 3 comprises an X-axis driving member 31, a sliding table 32, a clamping cylinder 33 and a material supporting assembly. The X-axis driving member 31 is selected from an electric module. The sliding table 32 is a plate-shaped structure, is horizontally installed on the X-axis driving member 31, is driven by the X-axis driving member 31 to translate along the X-axis direction, and is provided with the clamping cylinder 33 and the material supporting assembly.

[0058] The transfer mechanism 2 transfers the plate wire 4 to the clamping jaw of the clamping cylinder 33, and then drives the clamping cylinder 33 to translate by the X-axis driving member 31, so as to transport the plate wire to the clamp of the bending machine.

[0059] Referring to Figure 1 , Figures 3 to 8 The material supporting assembly is used for supporting and correcting the plate wire 4, so as to prevent the plate wire with the rear end hanging in the air from being inclined in the moving and pushing process. The material supporting assembly comprises a base 37 and a supporting plate 34 located on the base 37. The base 37 is fixed on the sliding table. The supporting plate 34 is provided with a protruding correction block one 35 and a correction block two 36 on the left side and the right side. When the plate wire 4 moves, the plate wire 4 passes through the correction block two 36 on the right side and translates closely to the correction block two 36.

[0060] Referring to Figure 2 , Figure 7 and Figure 8The two correction blocks are provided with X-direction dovetail grooves 351 penetrating the correction blocks horizontally, the support plate 221 is L-shaped, the bottom of the support plate 221 extends forward, and the bottom is fixed with a sliding rail 222 matched with the X-direction dovetail groove 351 near the end of the correction block. After the sliding rail 222 is translated into the X-direction dovetail groove 351 of the correction block one 35, the Y-axis module 22 drives the correction block and the supporting plate 34 to push the plate wire straight to the clamping jaw of the clamping cylinder 33 by using the special shape of the X-direction dovetail groove 351, and then the Y-axis module 22 drives the support plate 221 to reset backward, and the sliding rail 222 on the support plate 221 drives the correction block one 35 and the supporting plate 34 to reset backward together.

[0061] Wherein, please refer to Figure 10 The clamping cylinder 33 comprises an upper clamping jaw 331 and a lower clamping jaw 332 arranged oppositely, when the clamping cylinder 33 drives the clamping jaw to clamp, the main body part of the lower clamping jaw 332 is not higher than the supporting plate 34, so that the plate wire 4 can be pushed onto the lower clamping jaw 332 smoothly. The side of the lower clamping jaw 334 away from the supporting plate 34 is provided with an upper flange 333 extending along the X-axis direction, when the clamping cylinder 33 drives the clamping jaw to clamp, the upper flange 333 is close to the side wall of the plate wire, thereby cooperating with the correction block two to correct the plate wire 4 in the XY plane, avoiding the deflection of the plate wire 4.

[0062] In the embodiment, the meaning of the "main body part of the lower clamping jaw" is the part of the clamping surface of the lower clamping jaw except the upper flange 333, that is, only the height of the upper flange 333 is higher than the upper surface of the supporting plate 34 during clamping, so that the plate wire is pushed onto the lower clamping jaw and positioned by the upper flange 333.

[0063] The supporting plate 34 is provided with an avoiding groove 345, when the plate wire 4 is pushed onto the clamping jaw of the clamping cylinder 33, the avoiding groove 345 avoids the clamping jaw.

[0064] As shown in Figure 12 Due to the limitation of the whole device, the conveying plane of the cutting mechanism 1 is lower than the height of the clamp of the bending machine, and the chuck 241 of the finger cylinder 24 is at the same height as the conveying plane, so that the horizontal movement of the finger cylinder 24 can reliably clamp the front end of the plate wire; on the other hand, the clamping jaw of the clamping cylinder 33 is at the same height as the clamp of the bending machine, which is convenient for directly conveying the plate wire horizontally to the bending machine. The above height difference causes the height difference C between the clamping jaw of the clamping cylinder 33 and the chuck 241 of the finger cylinder, in order to ensure that the conveying action is carried out smoothly, the height difference needs to be eliminated during the transfer process. If the Z-axis module 23 is directly started to change the height of the finger cylinder 24, a movement beat needs to be reserved for the Z-axis module 23 during the transfer process, which reduces the feeding efficiency.

[0065] The embodiment solves the technical problem by the following structure:

[0066] Please refer toFigure 4 and Figure 5 The base plate 341 is installed on the base 37 and can slide horizontally along the Y-axis direction. The top of the base 37 is provided with a Y-direction dovetail groove 371, and the bottom of the base plate 341 is fixed with a guide rail matched with the Y-direction dovetail groove 371. The base plate 341 can slide along the Y-direction dovetail groove 371. The Y-direction dovetail groove 371 not only guides the base plate 341, but also positions the base plate 341 in the height direction, so that the base plate 341 does not lift off the base 37.

[0067] The base plate 341 is installed on the base 37 and can slide horizontally along the Y-axis direction. The top of the base 37 is provided with a Y-direction dovetail groove 371, and the bottom of the base plate 341 is fixed with a guide rail matched with the Y-direction dovetail groove 371. The base plate 341 can slide along the Y-direction dovetail groove 371. The Y-direction dovetail groove 371 not only guides the base plate 341, but also positions the base plate 341 in the height direction, so that the base plate 341 does not lift off the base 37.

[0068] The base plate 341 is installed on the base 37 and can slide horizontally along the Y-axis direction. The top of the base 37 is provided with a Y-direction dovetail groove 371, and the bottom of the base plate 341 is fixed with a guide rail matched with the Y-direction dovetail groove 371. The base plate 341 can slide along the Y-direction dovetail groove 371. The Y-direction dovetail groove 371 not only guides the base plate 341, but also positions the base plate 341 in the height direction, so that the base plate 341 does not lift off the base 37.

[0069] When any one of the correction blocks is pushed, the corresponding Y-direction rack 343 drives the same side gear 373 to rotate, and the same side gear 373 drives the other side gear 373 to rotate synchronously through the rotating shaft 372, and the other side gear 373 drives the corresponding Y-direction rack 343 to translate, so that the base plate 341 moves stably as a whole and does not appear to be skewed.

[0070] Please refer to Figure 5 and Figure 9 The base plate 341 is installed on the base 37 and can slide horizontally along the Y-axis direction. The top of the base 37 is provided with a Y-direction dovetail groove 371, and the bottom of the base plate 341 is fixed with a guide rail matched with the Y-direction dovetail groove 371. The base plate 341 can slide along the Y-direction dovetail groove 371. The Y-direction dovetail groove 371 not only guides the base plate 341, but also positions the base plate 341 in the height direction, so that the base plate 341 does not lift off the base 37.

[0071] Because the height of the lower clamp jaw 332 is higher than the height of the plate wire on the finger air cylinder 24 in the initial state, when the gear 373 is driven to rotate by the translating base plate 341, the gear 373 drives the Z-direction rack 382 to move upwards, the Z-direction rack 382 drives the top plate 342 to rise relative to the base plate 341, so that the height of the top plate is flush with that of the lower clamp jaw, thereby without the need to increase the driving device to correct, push and lift the plate wire into the lower clamp jaw 332 of the clamp cylinder 33, and their actions are completed synchronously, reducing the action rhythm and improving the work efficiency.

[0072] The top plate 342 of the embodiment is a high-density metal plate, such as a stainless steel plate. When the Z-direction rack 382 is lowered, the jacking force on the top plate disappears, and the top plate automatically lowers to the bottom plate 341 under its own weight.

[0073] Further, in order to enable the top plate 342 to be smoothly raised and lowered, at least one auxiliary guide 344 is fixed on the bottom plate 341, and a guide hole is provided on the top plate to cooperate with the auxiliary guide 344, so that the top plate 342 moves up and down along the auxiliary guide 344. Preferably, the auxiliary guide 344 is located on the side opposite the correction block, further improving the balance of the top plate; and the auxiliary guide 344 does not protrude out of the guide hole during pushing of the plate wire, avoiding interference with the pushing action of the plate wire.

[0074] Embodiment 2

[0075] Since the finger cylinder 24 is installed in the Y direction, the finger cylinder 24 itself has a certain width and height, and when it passes through the correction block, it may be blocked by the protruding correction block and difficult to move smoothly. The embodiment makes the following improvements to the correction block based on Embodiment 1:

[0076] The correction block includes a block body 352, a guide column 353, and an elastic member 354.

[0077] Please refer to Figure 6 and Figure 7 The bottom of the block body 352 is provided with a sliding groove 355 cooperating with the guide column 353, and the outer side of the block body 352 (i.e. the side close to the sliding rail 222 of the support plate) is provided with an X-direction dovetail groove 351. When the top plate is jacked up, the X-direction dovetail groove 351 is in an exposed state, so that the sliding rail 222 can be smoothly inserted into the X-direction dovetail groove 351. In order to enable the sliding rail to be more smoothly inserted into the X-direction dovetail groove 351, a certain gap is left between the X-direction dovetail groove 351 and the sliding rail 222 when they are in a cooperating state.

[0078] The guide column 353 is vertically fixed to the top surface of the bottom plate 341, and the guide column 353 extends into the sliding groove 355, so that when the block body 352 is pressed by the finger cylinder 24, it can move downward along the guide column 353 to avoid the finger cylinder 24.

[0079] The elastic member 354 is sleeved on the guide column 353, and the upper and lower ends of the elastic member 354 abut against the block body 352 and the bottom plate 341, respectively, for resetting the block body 352. The elastic member 354 can be a compression spring.

[0080] Chamfers 356 are provided on the left and right sides of the correction block, so that the finger cylinder 24 can smoothly press down the correction block.

[0081] Please refer to Figure 11The side of the finger cylinder 24 close to the slide rail 222 is the first side 242, the side of the slide rail 222 close to the finger cylinder 24 is the second side 223, the distance between the first side 242 and the second side 223 in the X direction is greater than the width of the correction block, so that the slide rail 222 and the finger cylinder 24 will not contact the correction block at the same time, that is, when the slide rail 222 pushes the correction block, the finger cylinder 24 does not contact the correction block, at this time the correction block is naturally lifted by the elastic member 354, the slide rail 222 and the correction block cooperate to complete the pushing work. When the finger cylinder 24 presses the correction block downward, the slide rail 222 is separated from the X-direction dovetail groove 351, so that the movement between them will not interfere.

[0082] When it is needed to turn over the plate wire and then feed, the clamping cylinder 33 can also be installed on the rotating cylinder 39 to turn over the plate wire.

[0083] The working process of the embodiment will be described below: Figure 11

[0084] The cutting mechanism 1 cuts the straightened plate wire, and the motor of the roller group 12 drives the plate wire to be horizontally conveyed to the finger cylinder 24;

[0085] The chuck 241 of the finger cylinder 24 clamps the front end of the plate wire, and is driven by the X-axis module 21 to horizontally drag the plate wire out of the roller group 12;
