Technical Field

[0001] This utility model belongs to the field of copper busbar processing technology, specifically a bending angle compensation device and bending equipment. Background Technology

[0002] In the production process of copper busbars, molds are needed to bend the copper busbars. In the existing technology, the molds for bending copper busbars are fixed structures. In order to reduce the holding time, the angle compensation amount is usually added to the original bending angle when designing the mold to improve the processing efficiency. However, this structure has the problem that the angle compensation amount is fixed, and when the product changes, the corresponding mold must be replaced to process it. Utility Model Content

[0003] Purpose of the utility model: To provide a bending angle compensation device and bending equipment that can drive the mold to rotate and adjust the bending angle compensation amount, thus solving the problem that the angle compensation amount of the existing mold is fixed and the corresponding mold needs to be replaced when the product changes.

[0004] The technical solution of this utility model is as follows: Firstly, a bending angle compensation device is installed on a bending equipment.

[0005] The bending angle compensation device includes: an angle compensation power source, an angle compensation linear displacement mechanism, and an angle compensation rotary mechanism.

[0006] The angle compensation power source is installed on the fixed frame of the bending equipment, the angle compensation rotation mechanism is installed on the mold of the bending equipment, and the angle compensation linear displacement mechanism connects the angle compensation power source and the angle compensation rotation mechanism.

[0007] When the angle compensation power source drives the angle compensation linear displacement mechanism to move, the angle compensation rotary mechanism drives the mold to rotate.

[0008] In a further embodiment of the first aspect, the two sets of the angle-compensated linear displacement mechanism and the angle-compensated rotation mechanism are disposed on both sides of the fixture.

[0009] The angle compensation power source includes a rotary motor and a synchronous belt drive mechanism. The synchronous belt drive mechanism is connected to the rotary motor, and the two sets of angle compensation linear displacement mechanisms are connected to the synchronous belt drive mechanism. This allows the rotary motor to drive the two angle compensation linear displacement mechanisms to move through the synchronous belt drive mechanism. This enables one rotary motor to drive two angle compensation linear displacement mechanisms to move through the synchronous belt drive mechanism, and it can simultaneously drive the clamp to rotate on both sides of the clamp, improving the synchronicity of the overall rotation of the clamp and the stability when it stops.

[0010] In a further embodiment of the first aspect, the angle-compensating linear displacement mechanism includes: a lead screw mechanism, the nut of the lead screw mechanism is installed on the synchronous belt drive mechanism, one end of the lead screw mechanism is engaged with the nut, and the other end is connected to the angle-compensating rotary mechanism. Through the self-locking function of the lead screw mechanism, the rotary mechanism can lock the linear displacement mechanism to the rotary mechanism when not in operation, thereby improving the working stability of the bending equipment.

[0011] In a further embodiment of the first aspect, the angle-compensating rotation mechanism includes: a slider, an eccentric shaft, a connector, and a rotating shaft.

[0012] The slider is mounted on the eccentric shaft, the eccentric shaft is mounted on the connector, and the connector and the rotating shaft are mounted on the mold of the bending equipment.

[0013] The slider connects to the fixed frame of the angle-compensating linear displacement mechanism and the clamping device, and the rotating shaft connects to the fixed frame of the bending device.

[0014] When the angle-compensated power source drives the slider to move through the angle-compensated linear displacement mechanism, the slider drives the eccentric shaft, connecting parts and mold to rotate around the rotation axis.

[0015] In a further embodiment of the first aspect, the slider is provided with a receiving cavity, the eccentric shaft is inserted into the receiving cavity, and the eccentric shaft is set at a predetermined distance from the upper and lower sides of the receiving cavity. By setting the eccentric shaft at a predetermined distance from the upper and lower sides of the receiving cavity, the force transmitted to the slider can be reduced when the clamping power source of the clamping device drives the mold to move, thereby improving the service life of the angle compensation linear displacement mechanism and the angle compensation rotation mechanism, and thus improving the service life of the bending equipment.

[0016] In a further embodiment of the first aspect, the eccentric shaft includes a square shaft portion.

[0017] The square shaft portion is inserted into the receiving cavity of the slider.

[0018] The square shaft portion and the left and right sides of the receiving cavity are planar sidewalls, and the square shaft portion and the left and right sides of the receiving cavity are dimensionally clearance-fitted.

[0019] During operation, the square shaft part is connected to one of the left and right sides of the receiving cavity, so that the slider drives the eccentric shaft to move. By cooperating with the planar sidewalls on the left and right sides of the receiving cavity, the square shaft part can be connected to the planar sidewalls when the slider drives the eccentric shaft to move, which improves the stability of the slider driving the eccentric shaft to move.

[0020] In a further embodiment of the first aspect, the fixed frame of the bending device is provided with a slide groove, the slider is installed in the slide groove, and the slider can move along the extension direction of the slide groove.

[0021] In a second aspect, a bending device includes: a clamping device and the bending angle compensation device described in the first aspect.

[0022] At least two of the clamping devices are distributed along a predetermined direction. The clamping devices are used to clamp the copper busbar. When the at least two clamping devices clamp the copper busbar, a height difference is generated at the bent part of the copper busbar.

[0023] The clamping device includes: a fixed frame, a clamping power source, and a mold.

[0024] The clamping power source is mounted on the fixed frame, and the mold is mounted on the clamping power source. The clamping power source is used to drive the mold to clamp the copper busbar.

[0025] At least one of the clamping devices is equipped with a bending angle compensation device, and the mold equipped with the bending angle compensation device is rotatably mounted on the clamping power source.

[0026] In a further embodiment of the second aspect, the mold equipped with the angle compensation device includes: a moving mold, a guiding mechanism, and a fixed mold.

[0027] The moving mold is mounted on a clamping power source. The moving mold is connected to a guiding mechanism. The guiding mechanism is connected to an angle-compensating rotation mechanism. The fixed mold is connected to an angle-compensating rotation mechanism.

[0028] When the angle compensation device is working, the angle compensation rotation mechanism drives the fixed mold and the guide mechanism to rotate together, and the guide mechanism drives the moving mold to rotate, which improves the overall integrity of the mold during rotation and thus improves the stability of the mold operation.

[0029] Thirdly, the processing method based on the bending equipment described in the second aspect includes: S100, using an angle compensation device to rotate the mold to a predetermined angle according to the compensation amount of the bending angle required for the copper busbar bending part.

[0030] S200. First, use a clamping device to hold the copper busbar and position it. Then, use other clamping devices to hold the copper busbar, so that the clamped parts of the copper busbar have a height difference, causing the copper busbar to be bent.

[0031] The beneficial effects of this utility model are as follows: This application uses an angle compensation power source, an angle compensation linear displacement mechanism, and an angle compensation rotation mechanism to drive the mold to rotate and adjust the bending angle compensation amount. It can increase the bending angle as needed based on the original design bending angle, reduce the impact of material springback, reduce the holding pressure time and improve processing efficiency. Moreover, the process of adjusting the bending angle compensation amount does not require changing the mold, which reduces the difficulty and cost of adjusting the bending angle. It solves the problem of the fixed angle compensation amount of the existing mold and the need to change the corresponding mold to process when the product changes. Attached Figure Description

However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0039] This utility model discloses a bending angle compensation device and bending equipment, which can drive the mold to rotate and adjust the bending angle compensation amount, solving the problem that the angle compensation amount of the existing mold is fixed and the corresponding mold needs to be replaced when the product changes.
