Description

Technical Field

[0001] This utility model relates to the technical field of metal profile processing equipment, and in particular to a copper-aluminum profile bending and positioning mechanism. Background Technology

[0002] As conductive connectors, copper and aluminum busbars require bending and punching during the production process, and the precision of the processing directly affects the assembly quality of the electrical cabinet.

[0003] In conventional processing, one method is to first punch holes in the straight copper or aluminum busbars and then bend them into shape. However, the metal material will experience elastic rebound during the bending process. This rebound deformation will cause the pre-punched holes to shift, which will seriously affect the dimensional accuracy of the final product.

[0004] To address the issue of hole misalignment, the industry has adopted an improved process of bending before punching. While this process avoids the impact of bending springback on the hole position, it introduces new processing challenges, namely, the irregular shape of the bent workpiece makes it difficult to achieve stable and precise positioning in the stamping die.

[0005] Existing stamping dies are mostly designed for flat sheet metal and use simple stops or pins for positioning. When used to process bent copper and aluminum bars, these positioning methods cannot effectively fit the bending shape of the workpiece. Under the huge impact force of stamping, the workpiece will move or deviate, resulting in inaccurate punching positions and making it impossible to guarantee the consistency of mass production.

[0006] Therefore, this utility model proposes a copper-aluminum strip bending and positioning mechanism to overcome the shortcomings of the prior art. Utility Model Content

[0007] In the existing technology, when the copper-aluminum busbar bending and positioning mechanism punches and positions the bent copper-aluminum busbar workpiece, there are problems such as the irregular shape of the workpiece making it difficult to hold stably, and the workpiece being prone to movement or skewing during punching, resulting in inaccurate punching positions. The present invention aims to provide a copper-aluminum busbar bending and positioning mechanism with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a copper-aluminum busbar bending and positioning mechanism for positioning processed materials. The copper-aluminum busbar bending and positioning mechanism includes a lower mold and an upper mold disposed above the lower mold and capable of vertical movement relative to the lower mold. The copper-aluminum busbar bending and positioning mechanism also includes a limiting mechanism disposed in an installation groove opened in the lower mold. A pressure block is fixedly connected to the upper mold. The limiting mechanism includes a movable positioning block, which is used to abut and clamp the processed material. The movable positioning block is slidably accommodated in the installation groove. The pressure block is vertically aligned with the movable positioning block. The limiting mechanism also includes a top pin and a spring disposed sequentially below the movable positioning block. The lower end of the spring abuts against a stop screw, which is threadedly connected to the bottom of the installation groove. The side wall of the movable positioning block and the groove wall of the installation groove form an inclined surface fit to convert vertical movement into horizontal contraction. The copper-aluminum busbar bending and positioning mechanism also includes a pushing mechanism, which is installed on the front side of the lower mold and is used to push the processed material after processing.

[0009] Preferably, the pushing mechanism includes a mounting box, which is fixed to the front side of the lower mold. The pushing mechanism also includes a threaded rod disposed in the mounting box and a threaded block threadedly connected to the threaded rod.

[0010] Preferably, in order to drive the threaded rod to rotate, the pushing mechanism also includes a knob and a fixing rod, the knob being located outside the mounting box, and the fixing rod being fixedly connected between the knob and the threaded rod.

[0011] Preferably, the fixing rod rotatably passes through the wall panel of the mounting box to transmit rotational power from the outside of the mounting box to the inside of the mounting box.

[0012] Preferably, to ensure smooth movement of the threaded block, a limiting block is fixedly connected to the threaded block, and the limiting block is slidably connected to the inner wall of the mounting box to provide guidance and support for the axial movement of the threaded block.

[0013] Preferably, to support the other end of the threaded rod, a rotating block is fixed inside the mounting box, and the rotating block is rotatably connected to the end of the threaded rod.

[0014] Preferably, in order to achieve push output, the mounting box is provided with a connecting groove, and the pushing mechanism also includes a moving block and a connecting plate. The moving block is slidably disposed in the connecting groove, and the two ends of the connecting plate are respectively rotatably connected to the rear side of the threaded block and the moving block, for transmitting the translational movement of the threaded block to the moving block.

[0015] Preferably, to avoid damaging the surface of the processed material, a rubber pad is fixedly connected to the front end of the moving block.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art of inaccurate hole positions caused by the springback of the copper and aluminum strips after bending, or the difficulty in positioning and clamping the workpiece after bending, by setting a limiting mechanism and using the pressure block to drive the movable positioning block to automatically retract and clamp when the upper mold moves downward. This allows the process of bending before punching to be implemented accurately, achieving the effect of ensuring the accuracy of the relative position of the hole and improving the precision of the product.

[0017] 2. This utility model solves the problem in the prior art that the workpiece is easily deformed or scratched due to bumps or manual handling when it is taken out after processing by setting a push mechanism controlled by a knob and using a moving block with a rubber pad at the front end to smoothly push the finished product. This achieves the effect of protecting the surface quality of the workpiece and improving the yield. Attached Figure Description

To protect the workpiece, a rubber pad 304 is fixedly connected to the front end of the moving block 303. The rubber pad 304 is used to contact and push the processing material 5 after processing is completed.

[0027] In a preferred embodiment, in order to improve the stability of the movement of the threaded block 308, the threaded block 308 is fixedly connected to a limiting block 309, and the limiting block 309 is slidably connected to the inner wall of the mounting box 301 to provide guidance for the translational movement of the threaded block 308.

[0028] In a preferred embodiment, in order to provide rotational support for the other end of the threaded rod 307, a rotating block 310 is fixed inside the mounting box 301, and the rotating block 310 is rotatably connected to the end of the threaded rod 307.

[0029] In a preferred embodiment, in order to convert the translation of the threaded block 308 into a pushing action, the mounting box 301 is provided with a connecting groove 302, and the pushing mechanism 3 also includes a moving block 303 and a connecting plate 311.

[0031] Working principle: Before processing, the upper mold 4 is in a raised state, and the spring 202 in the limiting mechanism 2 is in a stretched state. The spring 202 pushes the movable positioning block 204 upward through the top pin 203. The movable positioning block 204 opens outward under the action of cooperating with the inclined surface of the mounting groove 206. At this time, the processing material 5 can be placed on the lower mold 1 and fed between the movable positioning blocks 204. When the upper mold 4 moves downward, the pressure block 205 fixedly connected to the upper mold 4 first presses down the movable positioning block 204. During the downward movement, the movable positioning block 204 compresses the spring 202 and is forced to contract inward under the action of cooperating with the inclined surface of the mounting groove 206, thereby clamping the processing material 5. The upper mold 4 continues to move downward, driving the punching component to complete the punching of the processing material 5. After processing, the operator rotates the knob 305 of the pushing mechanism 3. The knob 305 drives the threaded rod 307 to rotate via the fixed rod 306. The fixed rod 306 rotates on the wall of the mounting box 301. The other end of the threaded rod 307 rotates in the rotating block 310. The rotation of the threaded rod 307 drives the threaded block 308 to move axially. The threaded block 308 drives the fixedly connected limit block 309 to slide along the inner wall of the mounting box 301. The threaded block 308 drives the moving block 303 via the rotating connecting plate 311. The moving block 303 slides in the connecting groove 302. The rubber pad 304 fixedly connected to the front end of the moving block 303 finally pushes the processed material 5 out of the mold.
