Description

Technical Field

[0001] The invention relates to the technical field of metal bending processing, and in particular to a copper bar bending machine. Background Art

[0002] Copper busbar bending refers to the process of bending and deforming the copper busbar according to the design requirements to make it into the required shape. In the production process, the copper busbar is mostly bent by a bending machine. The bending machine is provided with a mold for bending the copper busbar. The bending mold is usually composed of a bending knife and a die. In the related technology, when bending the copper busbar, it is first necessary to mark the specified position of the copper busbar according to the design requirements. Then the staff holds the copper busbar and puts it into the bending mold, and makes the marked position opposite to the bending mold. Then the bending knife and the die are driven to squeeze the copper busbar relatively close to each other, so that the copper busbar is bent at a certain angle. If the position of the copper busbar when bending is judged manually, the placement accuracy of the copper busbar relative to the bending mold may be inaccurate, which may affect the processing accuracy of the copper busbar.

[0003] The patent document with authorization announcement number CN220426406U discloses a copper busbar bending machine, including a base, a mounting plate fixedly connected to the top of the base, a placement plate fixedly connected to the top of the mounting plate, an auxiliary frame fixedly connected to the outer wall of the placement plate, a placement seat fixedly connected between the placement plate and the auxiliary frame, a transmission seat slidably connected between the placement plate and the auxiliary frame, slots are respectively provided at the ends of the placement seat and the transmission seat facing each other, and blocks are respectively inserted into the slots of the placement seat and the transmission seat, an electric cylinder is fixedly connected to the outer wall of the mounting plate, a sleeve is rotatably connected to the telescopic end of the electric cylinder, a connecting block is fixedly connected to the outer wall of the sleeve, and a stopper is fixedly connected to one end of the connecting block. The bending machine uses the scale of the stopper to adjust the bending position of the moving copper busbar, so that personnel can determine the processing position more accurately.

[0004] The bending machine provided by the above patent document sets a ruler so that the staff can refer to the placement position of the copper bar through the ruler parameters, thereby improving the accuracy of the copper bar placement. However, in the bending operation of the copper bar, the degree of dependence on manual operation is still high. When the copper bar is bent, it often needs to be bent in different directions. This requires the staff to take the copper bar out of the bending mold after the bending of the copper bar in one direction is completed, and then put it back in the opposite direction to bend the copper bar in the opposite direction, resulting in low processing efficiency in the copper bar bending operation. Summary of the invention

[0005] The present invention provides a copper bar bending machine, aiming to solve the problem that the copper bar needs to be taken out and placed again when the bending machine in the related art performs bending processing on the copper bar in different directions, and the bending operation is highly dependent on manual labor, resulting in low copper bar bending processing efficiency.

The two movable templates are hinged to the movable parts at the same time. When the two movable templates are relatively deflected, the elastic parts are squeezed to deform and accumulate force. The opposite side of the two groups of movable modules is taken as the outer side. The bending parts of the movable modules in the same group are located on the inner side of the movable parts, and the tip of the bending parts is opposite to the connection between the two movable templates.

[0028] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0029] like Figure 1 As shown, the copper bar bending machine of the present invention includes a body 1, on which a bending mechanism is provided. The bending mechanism includes two sets of movable modules arranged opposite to each other. When the copper bar 5 is bent, the copper bar 5 is placed between the two sets of movable modules. The two sets of movable modules are relatively close to and squeeze the copper bar 5 to perform the bending process on the copper bar 5.

[0030] like Figures 2 to 4 As shown, the movable module includes a movable part, a bending part and a driving part. Two movable templates 6 are respectively arranged on opposite sides of the two movable parts. The two movable templates 6 are hinged by an elastic part. The two movable templates 6 can be connected by a torsion spring. When the torsion spring is not subjected to force, the two movable templates 6 are in the same plane. The two movable templates 6 are hinged to the movable part at the same time. When the two movable templates 6 are relatively deflected, the elastic part is squeezed to deform and accumulate force. A sliding groove is arranged at the outer end of the movable part. The upper ends of the two movable templates 6 are slidably matched with the sliding groove. The opposite side of the two groups of movable modules is the outer side. The bending part of the movable mold group is located on the inner side of the movable part, and the tip of the bending part is opposite to the connection between the two movable templates 6. The driving part drives the movable part to move in the direction close to or away from the other group of movable modules. A cavity is formed inside the movable part. Two guide parts are also provided on the inner side of the movable part. The two guide parts are adjacent to the two movable templates 6. A gap for the bending part to pass through is formed between the two guide parts. The spacing between the two guide parts increases from the inside to the outside. The body 1 is also provided with a power part for driving any bending part to move in the direction close to or away from the other group of movable modules.

[0031] For the convenience of description, the bending part connected to the power part is bending part 1 21, the active module to which bending part 1 21 belongs is active module 1, the active part in active module 1 is active part 1 2, the bending part fixed relative to the body 1 is bending part 2 31, the active module to which bending part 2 31 belongs is active module 2, and the active part in active module 2 is active part 2 3.

[0032] Working state of bending mechanism 1: The driving member drives the movable member 2 3 to move backward, and the bending member 2 31 contacts the two movable templates 6 on the movable member 2 3, and pushes the hinges of the two movable templates 6 to extend forward relative to the movable member 2 3, so that the two movable templates 6 fit with the tips of the bending member 2 31 and adapt to the shape of the tips of the bending member 2 31, and the copper bar 5 is placed between the two groups of movable templates, and the position of the copper bar 5 to be bent is opposite to the convex ridges of the hinges of the two movable templates 6 on the movable member 2 3. At this time, the movable template 2 is used as a bending knife in the bending operation of the copper bar 5. The specific state is as follows: Figure 3 As shown; Afterwards, the driving member in the movable module 1 drives the movable member 1 2 to move along the position close to the copper bar 5. After the two movable templates 6 of the movable module 1 contact the copper bar 5, the movable templates 6 of the two groups of movable modules continue to approach and squeeze the copper bar 5, so that the copper bar 5 is gradually bent. The two movable templates 6 of the movable module 1 are synchronously bent with the copper bar 5 and deflected toward the inside of the movable member 1 2 until the two movable templates 6 abut against the guide part inside the movable member 2 3 and stop moving. At this time, the movable module 1 is used as a concave mold in the bending operation of the copper bar 5. The specific state is as follows: Figure 4 shown.

[0033] Working state 2 of the bending mechanism: In this working state, the bending direction of the copper busbar 5 is opposite to that in the working state one. When the operation in the working state two is executed, the movable part 2 3 moves forward, and the two movable templates 6 on the movable part 2 3 are reset under the action of the torsion spring, and the copper busbar 5 is placed against the two movable templates 6 on the front side of the movable part 2 3. At this time, the movable module 2 is used as a concave mold in the bending operation of the copper busbar 5. The driving part of the movable module 1 first drives the movable part 1 2 to move relative to the bending part 1 21, until the tip of the bending part 1 21 abuts against the two movable templates 6 on the movable part 1 2, and the shapes of the two movable templates 6 match the shape of the tip of the bending part 1 21. The movable module 1 is used as a bending knife in the bending operation of the copper busbar 5. After that, the driving part and the movable part of the movable module 1 work synchronously, driving the movable part 1 2 and the bending part 1 21 to move synchronously to a position close to the copper busbar 5, gradually squeezing the copper busbar 5 to deform and bend.

[0034] The driving part can be a cylinder or a combination of a motor and a screw. When the driving part is a cylinder, the driving end of the driving part can be directly connected to the corresponding movable part 2, bending part 21 or movable part 23. When the driving part is a combination of a motor and a screw, the driving end of the motor is connected to the screw, and the screw is threadedly matched with the movable part 2, bending part 21 or movable part 23.

[0035] When the bending mechanism bends the copper busbar 5, the two movable modules are automatically adjusted to be used as bending knives or concave dies according to the requirements of the bending direction of the copper busbar 5, so that the copper busbar 5 does not need to be taken out during the bending operation, and the copper busbar 5 can be flexibly bent in different directions, which can effectively improve the efficiency of the bending operation of the copper busbar 5.

[0036] When bending the copper busbar 5, in order to reduce scratches caused by frictional contact between the copper busbar 5 and the movable template 6, a roller is provided on the movable template 6, and the upper and lower ends of the roller are rotatably matched with the movable template 6. The roller is used to roll and fit with the copper busbar 5 to reduce the friction between the copper busbar 5 and the movable template 6.

[0037] When the copper bar 5 is bent, it is often necessary to bend the end of the copper bar 5. Since the overall length of the copper bar 5 is relatively long, when the end of the copper bar 5 is bent, the remaining part of the copper bar 5 will swing significantly on the machine body 1. Even during the bending process of the copper bar 5, the end away from the bending position will rotate to a position detached from the table of the machine body 1. The overall mass of the copper bar 5 is relatively large. When the end of the copper bar 5 is bent, the swing of the copper bar 5 itself may affect the stability of the bending position relative to the bending mechanism, causing the copper bar 5 to deviate relative to the bending mechanism, thereby affecting the accuracy and quality of the bending operation of the copper bar 5.

[0038] like Figure 1 and Figure 5 As shown, in order to further improve the stability of the copper busbar 5 during the bending operation, a guide mechanism is further provided on the machine body 1, and the guide mechanism includes a moving part 4, a guide assembly and a guide groove 12. The moving part 4 is elastically connected to the machine body 1, and the moving direction of the moving part 4 is parallel to the moving direction of the movable part. The guide assembly is slidably matched with the moving part 4, and the moving direction of the guide assembly is perpendicular to the moving direction of the moving part 4. The guide assembly is used to slidably match with the copper busbar 5. The guide groove 12 is opened on the machine body 1, and the guide assembly is slidably matched with the guide groove 12.

[0039] The guide assembly includes a driving source 41, a driving shaft 42, two gears 43 and two guide rollers 45. The driving source 41 can be a motor. The driving source 41 is slidably matched with the moving member 4. The driving end of the driving source 41 is connected to the driving shaft 42. A gear 43 is keyed to the driving shaft 42. The two gears 43 are meshed. The two guide rollers 45 are respectively fixed to the two gears 43. The two guide rollers 45 are connected by a connecting member 44. The guide rollers 45 are rotatably matched with the connecting member 44. The two guide rollers 45 are slidably matched with the guide groove 12. The copper bar 5 extends between the two guide rollers 45. The guide rollers 45 are in frictional contact with the copper bar 5. The driving source 41 is connected to the driving shaft 42 through a one-way bearing. The guide assembly can also be used to feed the copper bar 5. When the driving source 41 rotates, the two guide rollers 45 are driven to rotate synchronously in the opposite direction through the driving shaft 42 and the two gears 43, and the copper bar 5 is pushed to move under the action of friction.

[0040] When bending the copper bar 5, the copper bar 5 is placed between the two groups of movable modules, and the copper bar 5 is inserted between the two guide rollers 45. The guide rollers 45 can prevent the copper bar 5 from being offset in the longitudinal direction during the bending force, thereby improving the quality of the bending processing of the copper bar 5. When the copper bar 5 is bent, it will further drive the guide component to slide along the guide groove 12, limit the swing range of the copper bar 5, improve the overall stability of the copper bar 5 during the bending operation, reduce the shaking of the copper bar 5, and improve the accuracy of the bending processing of the copper bar 5. After the copper bar 5 is bent, the two movable modules are relatively far away, and the guide component is reset under the elastic force of the spring. The copper bar 5 can also be pushed by the guide component to move relative to the two groups of movable modules to the next bending position opposite to the two groups of movable modules, thereby reducing the dependence on manual labor during the bending operation, and further improving the efficiency and quality of the bending processing of the copper bar 5.

[0041] In order to further ensure the accuracy of the relative position between the copper busbar 5 and the movable module, a calibration component is also provided on the body 1, and the calibration component includes a cylinder and a calibration rod 11. The cylinder is installed on the body 1, and one end of the calibration rod 11 is connected to the protruding end of the cylinder. After the guide assembly pushes the copper busbar 5 into place, the calibration rod 11 is pushed by the cylinder to move to the specified position according to the design requirements to confirm whether the position of the copper busbar 5 is accurate.

[0042] The copper busbar bending machine provided by the present invention facilitates flexible adjustment of the bending direction of the copper busbar according to design requirements, reduces dependence on manual operation during the bending operation, and improves the work efficiency and processing accuracy of the copper busbar bending operation.
