Description

Technical Field

[0001] This utility model relates to the field of stationary contact bending technology, and specifically to a stationary contact segmented bending processing device. Background Technology

[0002] The stationary contact bending design allows the contact to form a specific curvature within a limited space, ensuring reliable contact and optimizing the arc extinguishing effect. Furthermore, bending can improve conductivity and heat dissipation efficiency by increasing the contact area or adjusting the current path. However, stationary contact bending requires the use of a stationary contact bending processing device.

[0003] According to the public announcement (CN211803239U), a circuit breaker stationary contact spring bending device is disclosed. This technology discloses a technical solution that includes "a frame, a worktable on the frame, a horizontally moving punch head and a stationary die matching the punch head on the worktable, a protrusion and a cavity on the vertical surface of the stationary die, which presses the workpiece into a bent part through the protrusion and cavity, and a blanking hole on the horizontal surface of the stationary die connected to the vertical surface, the shape of the blanking hole being consistent with the workpiece to be processed, and the workpiece being ejected from the blanking hole after being punched by the punch head. The punch head can press the workpiece against the vertical surface of the stationary die, so that the workpiece deforms according to the shape of the vertical surface, and the pressed workpiece matches the blanking hole, so that the pressed workpiece can be ejected from the blanking hole from the stationary die without manual removal, thus improving work efficiency."

[0004] However, the actual stationary contact has a complex shape and many parts that need to be bent. Therefore, segmented bending is required to achieve the processing effect of the stationary contact. Compared with the above documents, only single bending can be achieved, which cannot handle complex bending and cannot meet the needs of complex bending. In addition, existing equipment often requires multiple clamping and adjustment during the bending process, resulting in low processing efficiency and difficulty in ensuring the consistency of bending accuracy.

[0005] To address the aforementioned problems, this application proposes a segmented bending processing device for stationary contacts. Utility Model Content

[0006] This utility model addresses the technical problems existing in the prior art by providing a segmented bending processing device for static contacts.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A static contact segment bending processing device includes a worktable, a support is fixedly connected to the upper part of the worktable, a movable electric push rod is fixedly provided on the upper part of the support, a fixing mechanism is fixedly provided at the output end of the movable electric push rod, a bending electric push rod is fixedly provided on the upper part of the support, and a bidirectional bending mechanism is fixedly provided at the output end of the bending electric push rod.

[0008] The fixing mechanism includes a fixed clamping frame fixedly mounted on the output end of the movable electric actuator. A telescopic rod is fixedly connected to the side end of the fixed clamping frame, and a rotating block is fixedly connected to the end of the telescopic rod. A torsion spring is fixedly connected inside the rotating block, and a rotating clamping frame is rotatably connected to the inner wall of the rotating block. The end of the torsion spring is fixedly connected to the rotating clamping frame. Clamping bolts are threadedly connected to the upper parts of the rotating clamping frame and the fixed clamping frame, and clamping push plates are rotatably connected to the lower parts of the clamping bolts. By setting up the mechanism, the stationary contact can be fixed for bending, and the segmented bending operation is achieved by using the telescopic movement of the movable electric actuator to move the stationary contact.

[0009] The bidirectional bending mechanism includes a bidirectional bending frame fixed on the output end of the bending electric actuator. The upper and lower parts of the inner wall of the bidirectional bending frame are both fixed with a folding knife base. A quick-release folding knife is slidably connected to the side end of the folding knife base. By setting it up, the bidirectional bending frame can perform double-sided bending operation on the stationary contact through the quick-release folding knife when it moves up and down.

[0010] An auxiliary frame is fixedly connected to the inner wall of the workbench, and an auxiliary wheel is rotatably connected to the surface of the auxiliary frame. The surface of the auxiliary wheel is in rolling connection with the bidirectional bending frame. This design allows the bidirectional bending frame to be constrained by the auxiliary wheel when it moves up and down, thus making it more stable and preventing deviation.

[0011] The folding knife base has a slot inside, and a push block is fixedly connected inside the folding knife base. An elastic card is fixedly connected to the upper part of the quick-release folding knife, and a locking head is fixedly connected to the upper part of the elastic card. The folding knife base is slidably connected to the locking head through the slot. The upper part of the quick-release folding knife has a push groove, and the quick-release folding knife is slidably connected to the push block through the push groove. This design makes it easier to assemble and disassemble the quick-release folding knife on the folding knife base, so that different models of quick-release folding knives can be quickly changed according to the different needs of the bending surface during bending.

[0012] The beneficial effects of this utility model are as follows: the stationary contact arm is fixed by rotating the clamping bolt to press down the clamping push plate, and then the stationary contact arm is fixed by clamping. The moving electric push rod is started to move the part of the stationary contact arm that needs to be bent to the quick-release folding knife. The bending electric push rod is started, and the bidirectional bending frame is moved up or down according to the required bending angle. The bidirectional bending frame drives the quick-release folding knife to squeeze the stationary contact arm to bend it. The rotating clamping frame can rotate on the rotating block and change its length with the telescopic rod so as not to affect the bending effect. The segmented bending operation is realized by using the telescopic movement of the stationary contact head with the moving electric push rod.

[0013] When bending the stationary contact, it is sometimes necessary to change the quick-release folding blade to achieve different bending effects. In this case, quick disassembly and assembly can be achieved through the linkage of the elastic card, the card head, and the card slot. Attached Figure Description

[0025] Reference Figure 1 A segmented bending processing device for stationary contacts includes a worktable 1, a support 2 fixedly connected to the upper part of the worktable 1, a movable electric push rod 3 fixedly mounted on the upper part of the support 2, a fixing mechanism 4 fixedly mounted on the output end of the movable electric push rod 3, a bending electric push rod 5 fixedly mounted on the upper part of the support 2, and a bidirectional bending mechanism 6 fixedly mounted on the output end of the bending electric push rod 5. After the stationary contact is fixed by the fixing mechanism 4, the bending operation is performed by the bidirectional bending mechanism 6, and the segmented bending can be achieved by fixing in one step in conjunction with the movement of the movable electric push rod 3.

[0026] Reference Figure 1 - Figure 3 The fixing mechanism 4 includes a fixed clamping frame 401 fixedly mounted on the output end of the movable electric actuator 3. A telescopic rod 402 is fixedly connected to the side end of the fixed clamping frame 401. A rotating block 403 is fixedly connected to the end of the telescopic rod 402. A torsion spring 404 is fixedly connected inside the rotating block 403. A rotating clamping frame 405 is rotatably connected to the inner wall of the rotating block 403. The inner circumference of the rotating block 403 is equal to the outer circumference of the rotating clamping frame 405. The end of the torsion spring 404 is fixedly connected to the rotating clamping frame 405. Clamping bolts 406 are threadedly connected to the upper parts of the rotating clamping frame 405 and the fixed clamping frame 401, respectively. The inner walls of the rotating clamping frame 405 and the fixed clamping frame 401 at this point are respectively connected to the clamping bolts. The outer wall of 406 is adapted to the clamping bolt 406. The lower part of the clamping bolt 406 is rotatably connected to the clamping push plate 407. The outer circumference of the clamping bolt 406 is equal to the inner circumference of the clamping push plate 407. The stationary contact arm is placed inside the fixed clamping frame 401 and the rotating clamping frame 405. The clamping bolt 406 is rotated so that the clamping push plate 407 is pressed down to clamp and fix the stationary contact arm. When the stationary contact arm is bent by force, the rotating clamping frame 405 can rotate on the rotating block 403 and change its length with the telescopic rod 402 so as not to affect the bending effect. By setting, the stationary contact can be fixed so as to be bent, and the segmented bending operation is realized by using the telescopic movement of the moving electric push rod 3 to move the stationary contact.

[0027] Reference Figure 2 The bidirectional bending mechanism 6 includes a bidirectional bending frame 601 fixed on the output end of the bending electric actuator 5. The upper and lower parts of the inner wall of the bidirectional bending frame 601 are both fixed with a folding knife base 602. There are two folding knife bases 602. The side end of the folding knife base 602 is slidably connected with a quick-release folding knife 603, so that the bidirectional bending frame 601 can be bent on both sides by pressing the stationary contact through the quick-release folding knife 603 when it moves up and down.

[0028] Reference Figure 1 An auxiliary frame 7 is fixedly connected to the inner wall of the workbench 1. An auxiliary wheel 8 is rotatably connected to the surface of the auxiliary frame 7. The outer circumference of the auxiliary frame 7 is equal to the inner circumference of the auxiliary wheel 8. The surface of the auxiliary wheel 8 is in rolling connection with the bidirectional bending frame 601. By setting it up, the bidirectional bending frame 601 can be constrained by the auxiliary wheel 8 when it moves up and down, thus making it more stable and avoiding deviation.

[0029] Reference Figure 4 The folding knife base 602 has two slots 9 inside. A push block 10 is fixedly connected inside the folding knife base 602. Two elastic clips 11 are fixedly connected to the upper part of the quick-release folding knife 603. A clip head 12 is fixedly connected to the upper part of each elastic clip 11. The folding knife base 602 is slidably connected to the clip head 12 via the slots 9. The quick-release folding knife 603 has a push groove 13 on its upper part, and the quick-release folding knife 603 is slidably connected to the push block 10 via the push groove 13. The quick-release folding knife 603 is inserted directly into the folding knife base 602 through the clip 12 and popped out from the clip 9 to fix it. When it needs to be disassembled, pinch both sides of the quick-release folding knife 603 to move the clip 12 inward, and the elastic clip 11 will deform and bend. At this time, the quick-release folding knife 603 can be directly removed from the folding knife base 602, making the disassembly and assembly of the quick-release folding knife 603 on the folding knife base 602 faster. This allows for quick replacement of different models of quick-release folding knives 603 according to the different requirements of the bending surface when bending.

[0030] Working principle:

[0031] The stationary contact segment bending processing device first places the stationary contact arm inside the fixed clamping frame 401 and the rotating clamping frame 405. Rotating the clamping bolt 406 causes the clamping push plate 407 to press down, thereby clamping and fixing the stationary contact arm. The moving electric push rod 3 is activated to move the part of the stationary contact arm that needs to be bent to the quick-release bending knife 603. The bending electric push rod 5 is activated, and the bidirectional bending frame 601 is moved up or down according to the required bending angle. The bidirectional bending frame 601 drives the quick-release bending knife 603 to squeeze the stationary contact arm and bend it. When the stationary contact arm is bent under force, the rotating clamping frame 405 can rotate on the rotating block 403 and change its length in conjunction with the telescopic rod 402 so as not to affect the bending effect. The segment bending operation is achieved by using the telescopic movement of the stationary contact arm with the moving electric push rod 3.

[0032] When bending the stationary contact, the quick-release folding blade 603 sometimes needs to be replaced to achieve different bending effects. At this time, pinching both sides of the quick-release folding blade 603 causes the clamping head 12 to move inward, and the elastic card 11 to deform and bend. Then, the quick-release folding blade 603 can be directly removed from the folding blade base 602, and the quick-release folding blade 603 can be directly inserted into the inside of the folding blade base 602 through the clamping head 12 and popped out from the slot 9 to fix it, thereby achieving the effect of quick replacement of the quick-release folding blade 603.
