[0002] A capacitor is a device that holds charge, consisting of two conductors close to each other with a non-conductive insulating medium in between. The ability to hold charge is usually referred to as capacitance, represented by the letter C. Capacitors are one of the electronic components used in large quantities in electronic equipment, and are widely used in circuits for DC isolation, AC passing, coupling, bypassing, filtering, tuning circuits, energy conversion, and control.

[0003] Capacitor pins are two lead-out terminals of a capacitor, used to connect the capacitor to the circuit. The design and use of capacitor pins have an important impact on the performance and stability of the circuit. Capacitor pins are usually divided into two leads, positive and negative. The positive pin is usually marked with a positive sign or +, and the negative pin is usually marked with a negative sign or -. This is because the capacitor is a polar component, and there is a potential difference between the positive and negative poles.

[0046] The connection block 4 is arranged on the side wall of the base 1 , and mainly provides support for the control console 5 and the hydraulic pump 6 .

[0047] This capacitor pin forming device is composed of only a base 1, a stamping plate 2 and a top plate 3, and the three are installed on the same vertical line, which reduces the floor space and space occupied and has fewer components for processing the capacitor pins. That is, it can be achieved by the cooperation of the upper die 15 and the cutting knife 16 arranged at the bottom of the stamping plate 2 and the installation groove 11 and the knife groove 12 arranged at the top of the base 1. The processing flow is simple and the operation is convenient, which is suitable for use in small-scale factories.

[0048] Specifically, the base 1 can be a cube or a cuboid. In the present invention, preferably, the base 1 is a cuboid, and foot pads 8 are fixedly arranged at the four corners of the bottom. Through the arrangement of the foot pads 8, the device can not only avoid direct contact with the ground during the entire operation process, reducing the loss of the device body, but also maintain the stability of the equipment, and improve the accuracy of the device during operation. The four corners of the top of the base 1 are respectively provided with guide holes that are compatible with the size of the guide column 7. The guide holes are circular, and the guide column 7 is arranged in the guide holes. The area adjacent to the guide holes is provided with a limit block 9. The limit block 9 limits the up and down displacement of the stamping plate 2, avoids direct collision between the upper die 15 and the lower die 10, and reduces the loss of the device body caused by the device during operation. A plurality of lower molds 10 are arranged in the area adjacent to the limit block 9. A plurality of mounting grooves 11 are provided on the top of the lower mold 10. The mounting grooves 11 are composed of a long mounting groove 111 and a short mounting groove 112.

A plurality of knife grooves 12 are provided at one end adjacent to the mounting groove 11, and the knife groove 12 is deeper than the short mounting groove 112. A chip box 13 that matches the size of the knife groove 12 is movably provided in the knife groove 12. The chip box 13 is used to collect waste chips generated when the pin material is cut to avoid excessive accumulation of waste chips inside the knife groove 12, which would cause damage to the device body. A plurality of protrusions 19 are fixedly connected to the top of the chip box 13. The protrusions 19 make it easier to take the chip box 13 out of the knife groove 12, thereby facilitating the processing of waste chips inside the chip box 13.

[0049] The stamping plate 2 can be a cube or a cuboid. In the present invention, preferably, the stamping plate 2 is a cuboid. The four corners of the stamping plate 2 are respectively provided with guide holes that are adapted to the size of the guide posts 7. The guide holes are circular. The guide posts 7 pass through the guide holes to connect the base 1 with the stamping plate 2. A plurality of upper molds 15 are fixedly connected to the bottom of the stamping plate 2. The upper mold 15 consists of a long upper mold 151 and a short upper mold 152. The long upper mold 151 and the short upper mold 152 are adjacently arranged. The upper mold 15 is convex relative to the bottom of the pressure plate 2, wherein the height of the short upper mold 152 is higher than the height of the long upper mold 151, the short upper mold 152 is made of elastic material, and the long upper mold 151 is made of hard material. The size of the short upper mold 152 is adapted to the short mounting groove 112, and the size of the long upper mold 151 is adapted to the long mounting groove 111. The upper mold 15 and the mounting groove 11 are on the same vertical line, that is, when the upper mold 15 moves downward, it just falls into the mounting groove 11. A telescopic rod 18 is fixedly provided on one side adjacent to the long upper die 151, and a trimming knife 17 is fixedly provided on the free end of the telescopic rod 18. The trimming knife 17 is flush with the long upper die 151, and the trimming knife 17 can be used to cut off the excess pin material generated in the stamping process, and the cut waste chips fall into the corresponding chip collection box 13 respectively. A cutting knife 16 is fixedly provided adjacent to the trimming knife 17, and when the cutting knife 16 moves downward, it falls into the knife groove 12. The size of the cutting knife 16 is adapted to the knife groove 12, and the cutting knife 16 is higher than the short upper die 152. A hydraulic rod 14 is provided in the middle of the top of the stamping plate 2, and the hydraulic rod 14 can perform telescopic movement. The other end of the hydraulic rod 14 is fixedly connected to the bottom of the top plate 3. The four corners of the bottom of the top plate 3 are also provided with guide holes that are adapted to the size of the guide column 7. The guide holes are circular, and the guide column 7 passes through the guide holes. The top plate 3 is movably connected to the stamping plate 2 through the guide column 7. The stamping plate 2 can move up and down along the guide column 7. The hydraulic rod 14 drives the stamping plate 2 to move downward, and the stamping plate 2 drives the cutting knife 16 to move downward together. The side wall of the base 1 is fixedly connected with a connecting block 4, and the top wall of the connecting block 4 is provided with a control console 5. A hydraulic pump 6 is provided on one side of the control console 5, wherein the control console 5 and the hydraulic pump 6 are electrically connected, and the control console 5 controls the operation of the hydraulic pump 6, and the hydraulic pump 6 drives the hydraulic rod 14 to move up and down.

[0050] In actual operation, the control console 5 is started, and the control console 5 controls the operation of the hydraulic pump 6. The hydraulic pump 6 drives the hydraulic rod 14 to extend and retract up and down. The extension and retraction of the hydraulic rod 14 drives the stamping plate 2 to move up and down along the guide column 7. A plurality of cutting knives 16 arranged at the bottom of the stamping plate 2 move with the stamping plate 2, and the capacitor pins to be cut off are placed in a plurality of long mounting grooves 111, and the capacitor caps are placed in a plurality of short mounting grooves 112. The mounting grooves 11 have a fixing effect on the capacitors, thereby improving the accuracy of the capacitor pins during the cutting process, reducing the cutting deviation caused by the movement of the pin position when the cutting knife 16 is cutting, and improving the quality of the product. Several cutting knives 16 moving downward cut off the pins of the capacitor, and the cut-off pin waste enters each corresponding chip box 13 respectively. At this time, several cutting knives 16 also enter each corresponding knife groove 12 respectively. This process is achieved by the cooperation of the cutting knives 16 arranged at the bottom of the stamping plate 2 and the knife groove 12 arranged at the top of the base 1. The cutting process is simple, the operation is convenient, the area and space occupied are small, and it is suitable for use in small-scale factories.

[0051] Furthermore, the pins that have been cut off are also fixedly placed in a number of long installation grooves 111, and the capacitor caps are placed in a number of short installation grooves 112. The hydraulic rod 14 is extended and retracted up and down to drive the stamping plate 2 to move up and down. The upper molds 15 arranged at the bottom of the stamping plate 2 move together with the stamping plate 2. During the downward movement of the upper mold 15, the short upper molds 152 will gradually contact the capacitor caps arranged in the short installation grooves 112. Since the short upper mold 152 is made of elastic material, the capacitor cap will not be damaged during the descent of the short upper mold 152. As the short upper mold 152 continues to descend, the capacitor cap will be completely covered by the short upper mold 152. The short upper mold 152 further fixes the capacitor cap, which again improves the accuracy of the capacitor pins during the working process, reduces the deviation caused by the movement of the capacitor position, and improves the quality of the product. The upper molds 15 continue to move downward until the long upper mold 151 contacts the long installation groove 111 and squeezes the capacitor pins, thus completing the production of the capacitor pins. This process is achieved by the cooperation between the upper die 15 arranged at the bottom of the stamping plate 2 and the mounting groove 11 arranged at the top of the base 1. The processing flow is simple, the operation is convenient, the area and space occupied are small, and it is suitable for use in small-scale factories.

[0052] Furthermore, after the extrusion is completed, the capacitor pins will produce excess waste. The control console 5 controls the operation of the hydraulic pump 6 again. The hydraulic pump 6 drives the hydraulic rod 14 to extend and retract up and down to drive the stamping plate 2 to move up and down. The trimming knives 17 set at the bottom of the stamping plate 2 move with the stamping plate 2. At this time, the capacitor becomes more fixed under the dual support of the mounting groove 11 and the upper mold 15. The trimming knife 17 moves downward with the stamping plate 2 to trim the excess part of the capacitor pin. The trimmed waste also enters each corresponding chip box 13 respectively. After the above process is completed, the chip box 13 is taken out and the waste is poured out. This process is achieved by the cooperation of the trimming knife 17 set at the bottom of the stamping plate 2 and the mounting groove 11 set at the top of the base 1. The processing flow is simple, the operation is convenient, and the area and space occupied are small. It is suitable for use in small-scale factories.

[0053] The whole process of cutting, squeezing and trimming the capacitor pins described above is realized by the upper die 15, the cutting knife 16 and the trimming knife 17 arranged at the bottom of the stamping plate 2, and the installation groove 11 and the knife groove 12 arranged at the top of the base 1. The processing flow is simple, the operation is convenient, the area and space occupied are small, and it is suitable for use in small-scale factories.
