DETAILED DESCRIPTION

[0019] The present invention is further described below through specific implementation methods.

[0020] Reference Figures 1 to 4As shown, a frame forming device for a three-terminal bracket capacitor includes a base 1, a forming seat 2 arranged on the base 1, a forming knife 3 which can be moved up and down and is arranged on the forming seat 2 and can be opposite to the frame 7, a driving mechanism 4 arranged on the base 1 and connected to and driving the forming knife 3 to move up and down, an adjustment and positioning mechanism 5 arranged on the base 1 and abutting against the frame 7, and a limiting mechanism arranged between the frame 7 and the base 1. Specifically, a placement table 11 extending upward for placing the frame 7 is formed on the base 1.

[0021] The frame 7 includes a frame body 71 , a plurality of welding units 72 spaced apart on the frame body 71 , and a plurality of limiting holes 73 spaced apart along the length direction of the frame body 71 . Specifically, the limiting hole 73 is located between two adjacent welding units 72 .

[0022] The forming seat 2 includes a connecting block 21 connected to the base 1 and an extension block 22 arranged on the connecting block 21 and extending upward. The extension block 22 is provided with a movable cavity 23 for the forming knife 3 to move up and down. Specifically, the extension block 22 and the connecting block 21 are partially staggered and arranged above the welding unit 72, so that when the frame 7 is placed on the placement table 11, a certain gap is formed between the welding unit 72 and the corresponding connecting block 21; further, the extension block 22 includes an extension block main body 221 and a pressing block 222 detachably arranged on the extension block main body 221.

[0023] The forming knife 3 includes a connecting section 31 which can be moved up and down and is arranged in the forming seat 2, a forming part 31 arranged at the bottom of the connecting section 31 and in contact with the welding unit 72, and a connecting head 33 arranged at the upper end of the connecting section 31 and connected to the driving mechanism 4.

[0024] The driving mechanism 4 includes a rotating seat 41 arranged on the base 1, a rotating handle 42 rotatably arranged on the rotating seat 41, and a connecting rod 43 movably connected between the rotating handle 42 and the forming knife 3. When the frame 7 is formed, the rotating handle 42 is rotated downward, and under the action of the connecting rod 43 and the forming seat 2, the forming knife 3 is driven to move downward to form the welding unit 72 thereunder. The operation is simple and easy to implement. Specifically, the connecting rod 43 is movably connected to the connecting head 33, and a connecting groove 34 is formed on the connecting head 33 for the end of the connecting rod 43 to be embedded.

[0025] The adjustment and positioning mechanism 5 includes an adjustment block 51 arranged on the placement table 11 and movable back and forth relative to the forming knife 3, two positioning holes 52 relatively arranged on the placement table 11, two strip-shaped adjustment holes 53 relatively arranged on the adjustment block 51 and respectively opposite to the two positioning holes 52, and positioning bolts passing through the strip-shaped adjustment holes 53 and threadedly connected to the relative positioning holes 52. When the frame 7 is formed, the side surface of the adjustment block 51 abuts against the side edge of the frame 7 to prevent the frame 7 from shifting when the forming knife 3 is working, thereby ensuring the forming accuracy of the frame 7; specifically, the strip-shaped adjustment hole 53 extends along the moving direction of the adjustment block 51, so as to facilitate fine-tuning of errors existing in different batches of frames 7, so that the adjustment block 51 keeps abutting against the side edge of the frame 7, thereby ensuring the effective implementation of the forming process.

[0026] The limiting mechanism includes two limiting columns 6 which are spaced apart on the placing table 11 and can be respectively embedded in two adjacent limiting holes 73. The frame 7 is fixed by the cooperation between the limiting columns 6 and the relative limiting holes 73, so that the welding unit 72 is just located directly below the forming knife 3. There is no need for the operator to adjust and calibrate. While improving the forming efficiency of the frame 7, the forming accuracy of the frame 7 can also be effectively guaranteed.

[0027] When the frame 7 is formed, the frame 7 is placed on the placement table 11, the welding unit 72 to be formed is placed under the forming knife 3, and the limiting column 6 on the placement table 11 is embedded in the relative limiting hole 73, and the position of the adjustment block 51 is adjusted so that it is against the side of the frame 7 to complete the positioning of the frame 7; then the operator turns the rotating handle 42 downward, and under the action of the connecting rod 43 and the forming seat 2, the forming knife 3 is driven to move downward to form the welding unit 72 below it; then the frame 7 is moved upward to disengage the limiting column 6 from the limiting hole 73, and the above operation is repeated to complete the forming process of multiple welding units 72 one by one.

[0028] The frame forming device limited by the present application has a simple overall structure and is easy to operate. The forming knife 3 that moves up and down performs the forming process on multiple welding units 72 on the frame one by one to solve the problem that there is no forming device in the three-terminal bracket capacitor frame in the prior art. The frame 7 is fixed by the cooperation of the limiting column 6 and the limiting hole 73, so that the welding unit 72 is just located directly below the forming knife 3, and there is no need for the operator to adjust and calibrate. While improving the forming efficiency of the frame 7, the forming accuracy of the frame 7 can also be effectively guaranteed.

[0029] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the scope of application of the present invention and the contents of the specification should still fall within the scope covered by the present invention.
