Description

Technical Field

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

[0002] The bending process of copper bars refers to the process of bending copper bars according to design requirements to make them into the required shapes. During the production process, copper bars are usually bent by a bending machine. The bending machine is provided with a die for bending copper bars. The bending die generally consists of a bending knife and a concave die. In the related art, when bending copper bars, first, marks need to be made at the specified positions of the copper bars according to the design requirements. Then, the staff holds the copper bars and puts them into the bending die, and aligns the marked positions with the bending die. Then, the bending knife and the concave die are driven to move closer to each other to squeeze the copper bars, so that the copper bars are bent at a certain angle. Only relying on manual judgment of the placement position of the copper bars during bending may result in inaccurate placement accuracy of the copper bars relative to the bending die, which may affect the processing accuracy of the copper bars.

[0003] The patent document with the authorization announcement number CN220426406U discloses a copper bar bending machine, which includes a base. A mounting plate is fixedly connected to the top of the base. A placement plate is fixedly connected to the top of the mounting plate. An auxiliary frame is fixedly connected to the outer wall of the placement plate. A placement seat is fixedly connected between the placement plate and the auxiliary frame. A transmission seat is slidably connected between the placement plate and the auxiliary frame. Slots are respectively opened at one ends of the placement seat and the transmission seat facing each other. Plug 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. The telescopic end of the electric cylinder is rotatably connected to a sleeve. A connecting block is fixedly connected to the outer wall of the sleeve. One end of the connecting block is fixedly connected to a stop scale. This bending machine uses the scale of the stop scale to adjust and move the bending part of the copper bar, enabling personnel to more accurately determine the processing position.

[0004] The bending machine provided in the above patent document improves the placement accuracy of copper bars by setting a stop scale, enabling the staff to refer to the stop scale parameters for the placement position of the copper bars. However, in the bending processing operation of copper bars, the dependence on manual operation is still relatively high. When the copper bars are bent, they often need to be bent in different directions. This requires the staff to take out the copper bars from the bending die after bending in one direction and then re-align and put them in to bend the copper bars in the reverse 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 in the related art, when the bending machine bends copper bars in different directions, the copper bars need to be taken out and placed again, and the dependence on manual labor during the bending operation is high, resulting in low processing efficiency of copper bar bending.

[0006] A copper bar bending machine of the present invention includes a machine body, and a bending mechanism is provided on the machine body. The bending mechanism includes two sets of relatively arranged movable modules;

[0007] The movable module includes a movable part, a bending part and a driving part. Two movable templates are provided on each of the opposite sides of the two movable parts. The two movable templates are hinged by an elastic part, and the two movable templates are simultaneously hinged to the movable part. When the two movable templates deflect relatively, the elastic part is squeezed and deformed and stores energy. Taking the side where the two sets of movable modules face each other as the outer side, the bending part of the same set of movable modules is located inside the movable part, and the tip of the bending part is opposite to the connection part of the two movable templates. The driving part drives the movable part to move in a direction close to or away from the other set of movable modules;

[0008] The machine body is also provided with a power part for driving any one of the bending parts to move in a direction close to or away from the other set of movable modules.

[0009] The beneficial effects are as follows: It is convenient to flexibly adjust the bending direction of the copper bar according to the design requirements. By adjusting the relative positions of the bending part and the movable part in the two sets of movable modules, the use functions of the two sets of movable modules as the female die in the bending operation can be replaced. When the bending direction needs to be changed during the bending of the copper bar, there is no need to take out the copper bar and put it in again, which greatly improves the working efficiency of the copper bar during multiple bending operations in different directions.

[0010] Preferably, a cavity is formed inside the movable part, and two guiding parts are further provided on the inner side of the movable part. The two guiding parts are arranged adjacent to the two movable templates.

The moving part is elastically connected to the machine body. The moving direction of the moving part is parallel to the moving direction of the movable part. The guiding component is slidably matched with the moving part. The moving direction of the guiding component is perpendicular to the moving direction of the moving part. The guiding component is used for slidably matching with the copper bar. The guiding groove is opened on the machine body, and the guiding component is slidably matched with the guiding groove.

[0013] The beneficial effects are as follows: improving the precision and quality of the copper bar bending operation. When the copper bar is bent, it drives the guiding component to slide along the guiding groove, limits the swinging range of the copper bar, reduces the longitudinal offset of the copper bar during the bending force application process, improves the overall stability of the copper bar during the bending operation, reduces the shaking of the copper bar, and improves the precision of the copper bar bending process.

[0014] Preferably, the guiding component includes a driving source, a driving shaft, two gears and two guiding rollers. The driving source is slidably matched with the moving part. The driving end of the driving source is connected to the driving shaft. One of the gears is key-connected to the driving shaft. The two gears are meshed. The two guiding rollers are respectively fixed to the two gears. The two guiding rollers are connected by a connecting piece. The guiding roller is rotationally matched with the connecting piece. The two guiding rollers are slidably matched with the guiding groove. The copper bar extends between the two guiding rollers.

[0015] Preferably, the guiding roller is in frictional contact with the copper bar, and the driving source and the driving shaft are connected by a one-way bearing.

[0016] The beneficial effects are as follows: realizing the automatic feeding operation during the copper bar bending operation. When the driving source rotates, it drives the two guiding rollers to rotate synchronously and reversely through the driving shaft and the two gears, and under the action of friction, it pushes the copper bar to move. The guiding component pushes the copper bar to move relative to the two groups of movable modules until it is opposite to the two groups of movable modules at the next position to be bent, reducing the dependence on manual operation during the bending process, and further improving the efficiency and quality of the copper bar bending process.

[0017] Preferably, a calibration component is further provided on the machine body. The calibration component includes a cylinder and a calibration rod. The cylinder is installed on the machine body, and one end of the calibration rod is connected to the extending end of the cylinder.

[0018] The beneficial effects are as follows: further ensuring the precision of the relative position between the copper bar and the movable module. When the two groups of movable modules are opposite at the position where the copper bar is pushed in place and to be bent, the cylinder pushes the calibration rod to move to the designated position according to the design requirements to confirm whether the position of the copper bar is accurate.

[0019] Preferably, rollers are provided on the movable template. The upper and lower ends of the rollers are rotationally matched with the movable template, and the rollers are used for rolling contact with the copper bar.

[0020] The beneficial effects are as follows: reducing the scratches generated by the frictional contact between the copper bar and the movable template. The rollers are used for rolling contact with the copper bar, reducing the frictional force between the copper bar and the movable template.

[0021] Preferably, the driving member includes a motor and a lead screw. The driving end of the motor is fixed to the lead screw. The lead screw is in threaded cooperation with the movable member. The movable member slides along the upper end surface of the machine body.

[0022] The beneficial effects of the present invention are as follows:

By adjusting the relative positions of the bending parts and the movable parts in the two groups of movable modules, the use functions of the two groups of movable modules as the female die in the bending operation can be replaced. When the bending direction needs to be changed during the bending of the copper bar, there is no need to take out the copper bar and put it in again, which greatly improves the working efficiency of the copper bar during multiple bending operations in different directions.

[0024] (2) Improve the accuracy and quality of the copper bar bending operation. When the copper bar is bent, it drives the guiding component to slide along the guiding groove, limits the swinging range of the copper bar, reduces the longitudinal offset of the copper bar during the bending force application process, improves the overall stability of the copper bar during the bending operation, reduces the shaking of the copper bar, and improves the accuracy of the copper bar bending process;

[0033] Embodiments of the present invention will be 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 are intended to explain the present invention, and should not be construed as limiting the present invention.

[0034] As Figure 1 shown, the copper bar bending machine of the present invention includes a machine body 1, and a bending mechanism is provided on the machine body 1. The bending mechanism includes two sets of relatively arranged movable modules. When bending the copper bar 5, the copper bar 5 is placed between the two sets of movable modules, and the two sets of movable modules approach and squeeze the copper bar 5 relatively to bend the copper bar 5.

[0035] As Figures 2 to 4 shown, the movable module includes a movable part, a bending part and a driving part. Two movable templates 6 are provided on each of the opposite sides of the two movable parts. The two movable templates 6 are hinged by an elastic member. The two movable templates 6 can be connected by a torsion spring. When the torsion spring is not stressed, the two movable templates 6 are in the same plane. The two movable templates 6 are simultaneously hinged to the movable part. When the two movable templates 6 deflect relatively, the elastic member is deformed and stores energy. A chute is provided at the outer end of the movable part. The upper ends of the two movable templates 6 are slidably matched with the chute. Taking the side where the two sets of movable modules face each other as the outside, the bending parts of the same set of movable modules are located inside the movable part, and the tip of the bending part is opposite to the connection part of the two movable templates 6. The driving part drives the movable part to move in a direction close to or away from the other set of movable modules. A cavity is formed inside the movable part. Two guiding parts are further provided inside the movable part. The two guiding parts are arranged adjacent to the two movable templates 6. A gap for the bending part to pass through is formed between the two guiding parts. The distance between the two guiding parts increases from the inside to the outside. A power part for driving any one of the bending parts to move in a direction close to or away from the other set of movable modules is further provided on the machine body 1.

[0036] For the convenience of description, the bending part connected to the power part is the first bending part 21, the movable module to which the first bending part 21 belongs is the first movable module, the movable part in the first movable module is the first movable part 2, the bending part fixed relative to the machine body 1 is the second bending part 31, the movable module to which the second bending part 31 belongs is the second movable module, and the movable part in the second movable module is the second movable part 3.

[0037] The first working state of the bending mechanism:

[0038] The driving member drives the second movable member 3 to move backward. The second bending member 31 contacts the two movable templates 6 on the second movable member 3, and pushes the hinge joints of the two movable templates 6 to protrude forward relative to the second movable member 3, so that the two movable templates 6 fit the tip of the second bending member 31, and adapt to the shape of the tip of the second bending member 31. Place the copper row 5 between the two sets of movable modules, and make the position of the copper row 5 to be bent opposite to the convex rib where the two movable templates 6 on the second movable member 3 are hinged. At this time, the second movable module is used as a bending knife in the bending operation of the copper row 5. The specific state is as Figure 3 shown;

[0039] After that, the driving member in the first movable module drives the first movable member 2 to move along the position close to the copper row 5. After the two movable templates 6 of the first movable module contact the copper row 5, the movable templates 6 of the two movable modules continuously approach and squeeze the copper row 5, so that the copper row 5 is gradually bent. The two movable templates 6 of the first movable module are bent synchronously with the copper row 5 and deflect inward the first movable member 2, and stop moving until the two movable templates 6 abut against the guiding part inside the second movable member 3. At this time, the first movable module is used as a concave die in the bending operation of the copper row 5. The specific state is as Figure 4 shown.

[0040] The second working state of the bending mechanism:

[0041] In this working state, the bending direction of the copper row 5 is opposite to that in the first working state. When performing the operation in the second working state, the second movable member 3 moves forward, and the two movable templates 6 on the second movable member 3 are reset under the action of the torsion spring. Place the copper row 5 against the two movable templates 6 on the front side of the second movable member 3. At this time, the second movable module is used as a concave die in the bending operation of the copper row 5. The driving member of the first movable module first drives the first movable member 2 to move relative to the first bending member 21 until the tip of the first bending member 21 abuts against the two movable templates 6 on the first movable member 2, and the shapes of the two movable templates 6 adapt to the shape of the tip of the first bending member 21. The first movable module is used as a bending knife in the bending operation of the copper row 5. After that, the driving member and the movable member of the first movable module work synchronously, driving the first movable member 2 and the first bending member 21 to move synchronously towards the position close to the copper row 5, and gradually squeezing the copper row 5 to deform and bend.

[0042] The driving member can be a cylinder or a combination of a motor and a lead screw. When the driving member is a cylinder, directly connect the driving end of the driving member to the corresponding first movable member 2, first bending member 21 or second movable member 3. When the driving member is a combination of a motor and a lead screw, the driving end of the motor is connected to the lead screw, and the lead screw is in threaded cooperation with the first movable member 2, first bending member 21 or second movable member 3.

[0043] When the bending mechanism bends the copper bar 5, according to the requirement of the bending direction of the copper bar 5, it automatically adjusts two movable modules to be used as bending knives or concave dies, so that the copper bar 5 can be bent in different directions without taking out the copper bar 5 during the bending operation, which can effectively improve the efficiency of the bending operation of the copper bar 5.

[0044] When bending the copper bar 5, in order to reduce the scratches generated by the frictional contact between the copper bar 5 and the movable template 6, rollers are provided on the movable template 6. The upper and lower ends of the rollers are rotationally matched with the movable template 6, and the rollers are used to roll and fit with the copper bar 5 to reduce the frictional force between the copper bar 5 and the movable template 6.

[0045] When the copper bar 5 is bent, it is often necessary to bend the end of the copper bar 5. Because the overall length of the copper bar 5 is relatively long, when bending the end of the copper bar 5, the remaining part of the copper bar 5 will swing greatly on the machine body 1. Even during the bending process of the copper bar 5, the end far from the bending place will rotate to a position where it is separated from the table surface of the machine body 1. The overall mass of the copper bar 5 is relatively large. When bending its end, the swing of the copper bar 5 itself may affect the stability between its bending place and the bending mechanism, causing the copper bar 5 to deviate relative to the bending mechanism and affecting the accuracy and quality of the bending operation of the copper bar 5.

[0046] Such as Figure 1 and Figure 5 As shown, in order to further improve the stability during the bending operation of the copper bar 5, a guiding mechanism is also provided on the machine body 1. The guiding mechanism includes a moving part 4, a guiding component and a guiding groove 12. The moving part 4 is elastically connected to the machine body 1. The moving direction of the moving part 4 is parallel to the moving direction of the moving part. The guiding component is slidably matched with the moving part 4. The moving direction of the guiding component is perpendicular to the moving direction of the moving part 4. The guiding component is used for slidably matching with the copper bar 5. The guiding groove 12 is opened on the machine body 1, and the guiding component is slidably matched with the guiding groove 12.

[0047] The guiding component includes a driving source 41, a driving shaft 42, two gears 43 and two guiding rollers 45. The driving source 41 can be a motor. The driving source 41 is slidably matched with the moving part 4. The driving end of the driving source 41 is connected to the driving shaft 42. One gear 43 is key-connected to the driving shaft 42. The two gears 43 are meshed. The two guiding rollers 45 are respectively fixed to the two gears 43. The two guiding rollers 45 are connected by a connecting piece 44. The guiding rollers 45 are rotationally matched with the connecting piece 44. The two guiding rollers 45 are slidably matched with the guiding groove 12. The copper bar 5 extends between the two guiding rollers 45. The guiding rollers 45 are in frictional contact with the copper bar 5. The driving source 41 and the driving shaft 42 are connected by a one-way bearing. The guiding component can also be used for feeding the copper bar 5. When the driving source 41 rotates, it drives the two guiding rollers 45 to rotate synchronously and in opposite directions through the driving shaft 42 and the two gears 43, and pushes the copper bar 5 to move under the action of frictional force.

[0048] When bending the copper bar 5, place the copper bar 5 between two sets of movable modules. At the same time, insert the copper bar 5 between two guide rollers 45. The guide rollers 45 can prevent the copper bar 5 from shifting longitudinally during the process of being bent, improving the quality of the bending process of the copper bar 5. When the copper bar 5 is bent, it will further drive the guide assembly to slide along the guide groove 12, limit the swinging 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 bending accuracy of the copper bar 5. After the copper bar 5 is bent, the two movable modules move relatively away from each other, and the guide assembly resets under the elastic force of the spring. The guide assembly can also push the copper bar 5 to move relative to the two sets of movable modules to the next position to be bent and face the two sets of movable modules, reducing the dependence on manual labor during the bending operation and further improving the bending efficiency and quality of the copper bar 5.

[0049] To further ensure the accuracy of the relative position between the copper bar 5 and the movable module, a calibration assembly is also provided on the machine body 1. The calibration assembly includes a cylinder and a calibration rod 11. The cylinder is installed on the machine body 1, and one end of the calibration rod 11 is connected to the extending end of the cylinder. After the guide assembly pushes the copper bar 5 into place, the cylinder pushes the calibration rod 11 to move to a specified position according to the design requirements to confirm whether the position of the copper bar 5 is accurate.

[0050] The copper bar bending machine provided by the present invention is convenient for flexibly adjusting the bending direction of the copper bar according to the design requirements, reducing the dependence on manual operation during the bending operation, and improving the working efficiency and processing accuracy of the copper bar bending operation.
