Abstract
Description
Technical Field
[0001] This utility model relates to the field of capacitor aluminum shell stamping die technology, and more specifically, it relates to a capacitor aluminum shell stamping die. Background Technology
[0002] A capacitor is generally a device that stores electrical charge. Capacitors are among the most widely used electronic components in electronic devices, extensively applied in circuits for DC blocking and AC passing, coupling, bypassing, filtering, tuning circuits, energy conversion, and control. A capacitor consists of two metal electrodes with an insulating dielectric layer between them. When a voltage is applied between the two metal electrodes, charge is stored on the electrodes, making the capacitor an energy storage element. Any two conductors that are insulated from each other and very close together form a capacitor. In circuits, capacitors are housed in aluminum casings, which are traditionally obtained by stamping using a die.
[0003] A search revealed that Chinese utility model patent application number CN201720957645.3 discloses a novel capacitor aluminum shell stamping die structure, including a lower die base, guide sleeves symmetrically arranged on the lower die base, guide posts arranged on the guide sleeves, an upper die base located at the end of the guide post away from the guide sleeve, a punch fixing plate located on one side of the upper die base, a first through hole on the upper die base, a die shank slidably connected to the upper die base inserted into the first through hole, one end of the die shank being connected to the punch fixing plate, a punch located on the side of the punch fixing plate away from the upper die base, a die fixing plate located on the lower die base, a die located on one side of the die fixing plate, and the die fixing plate being located between two guide sleeves.
[0004] In use, the punch moves downward to squeeze the aluminum plate, and the punch and die work together to stamp the aluminum plate into the required shape of the capacitor aluminum shell. After stamping, the capacitor aluminum shell will get stuck outside the punch or inside the die, making it inconvenient for workers to remove the stamped capacitor aluminum shell. The difficulty in removing the stamped capacitor aluminum shell leads to a decrease in the stamping efficiency of the capacitor aluminum shell. Utility Model Content

[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution: a capacitor aluminum shell stamping die, comprising a base, a punch, and a die. A fixing frame is fixedly connected to the top of the base, and a first hydraulic cylinder is fixedly connected to the fixing frame. A fixing plate is fixedly connected to the bottom of the first hydraulic cylinder. The punch is detachably mounted on the bottom of the fixing plate. Two second hydraulic cylinders are fixedly connected to the fixing frame, and push plates are fixedly connected to the bottom of the two second hydraulic cylinders. The push plates are provided with through slots adapted to the punch. A fixing seat is fixedly connected to the top of the base, and the fixing seat is provided with... The die has a groove, and a third hydraulic cylinder is fixedly connected to the bottom of the groove. A slide plate is fixedly connected to the top of the third hydraulic cylinder, and a top plate is fixedly connected to the top of the slide plate. Both top plates are slidably engaged with the fixed base. The die is detachably installed on the top of the fixed base. The die has two vertical grooves, and the two top plates are slidably engaged with the two vertical grooves respectively. This facilitates the removal of the capacitor aluminum shell that is stuck outside the punch or inside the die, making it easier for people to remove the capacitor aluminum shell. This reduces the inconvenience of removing the stamped capacitor aluminum shell and improves the stamping efficiency of the capacitor aluminum shell.
[0009] The present invention is further configured such that a convex groove is provided at the bottom end of the fixing plate, and a convex seat is fixedly connected to the top end of the punch, the convex seat and the convex groove are slidably engaged, which facilitates the replacement of the punch.
[0010] The present invention is further provided that the fixing plate is threaded with a first screw that mates with the convex seat, so as to facilitate the fixing of the convex seat.
[0011] The present invention is further configured such that the top of the fixed base is provided with two slots, and the bottom of the die is fixedly connected with two sockets, the two sockets being inserted into the two slots respectively, so as to facilitate the disassembly and replacement of the die.
[0012] The present invention is further configured such that a second screw that mates with the socket is threaded onto the fixing base, which facilitates fixing the socket.
[0013] The present invention is further configured such that a first electric cylinder is fixedly connected to both the left and right sides of the fixed base on the fixed frame, and a side positioning plate is fixedly connected to the telescopic end of the first electric cylinder, which plays a positioning role on the side end of the plate of the stamped capacitor aluminum shell.

[0016] (III) Beneficial Effects
[0017] Compared with the prior art, the present invention provides a stamping die for aluminum capacitor shells, which has the following advantages:
[0018] 1. When the capacitor aluminum shell is stuck on the punch, the ejector plate pushes the aluminum shell stuck outside the punch down during the upward movement of the punch. When the aluminum shell is stuck inside the die, the third hydraulic cylinder pushes the slide plate and two top plates upward. The two top plates push against the sides of the aluminum shell, pushing the aluminum shell out from inside the die. This makes it easier to remove the aluminum shell stuck outside the punch or inside the die, making it easier to handle. This reduces the inconvenience of handling the stamped aluminum shell and improves the stamping efficiency of the aluminum shell.
[0019] 2. Since the punch is connected to the fixed plate through the punch seat, and the die is inserted into the slot through the socket and connected to the fixed plate, the punch and die can be fixed separately by tightening the first screw and the second screw, which makes it easy to replace the punch and die.

[0030] Please see Figures 1-5A capacitor aluminum shell stamping die includes a base 1, a punch 2, and a die 3. A fixing frame 4 is fixedly connected to the top of the base 1, and a first hydraulic cylinder 5 is fixedly connected to the fixing frame 4. A fixing plate 6 is fixedly connected to the bottom of the first hydraulic cylinder 5. The punch 2 is detachably mounted on the bottom of the fixing plate 6. Two second hydraulic cylinders 7 are fixedly connected to the fixing frame 4, and push plates 8 are fixedly connected to the bottom of the two second hydraulic cylinders 7. The push plates 8 are provided with through grooves 9 that are adapted to the punch 2. A fixing seat 10 is fixedly connected to the top of the base 1, and a groove 11 is provided on the fixing seat 10. The bottom of the groove 11 is fixedly mounted on the fixing seat 10. A third hydraulic cylinder 12 is fixedly connected, and a slide plate 13 is fixedly connected to the top of the third hydraulic cylinder 12. A top plate 14 is fixedly connected to the top of the slide plate 13. Both top plates 14 are slidably engaged with the fixed seat 10. The die 3 is detachably installed on the top of the fixed seat 10. Two vertical grooves 15 are provided on the die 3. The two top plates 14 are slidably engaged with the two vertical grooves 15 respectively. The two top plates 14 are located on both sides of the upper mold groove of the die 3, so that the top plates 14 can push the capacitor aluminum shell out by pushing against the edge of the capacitor aluminum shell, avoiding the top plates 14 being placed inside the die 3, so as to avoid affecting the stamping effect of the capacitor aluminum shell.
[0031] Specifically, when the capacitor aluminum shell is stuck on the punch 2, the pusher plate 8 pushes the capacitor aluminum shell stuck outside the punch 2 down during the upward movement of the punch 2. When the capacitor aluminum shell is stuck inside the die 3, the third hydraulic cylinder 12 pushes the slide plate 13 and the two top plates 14 upward. The two top plates 14 push against the sides of the capacitor aluminum shell, pushing the capacitor aluminum shell out from inside the die 3. This makes it easier to push the capacitor aluminum shell stuck outside the punch 2 or inside the die 3 down, making it easier for people to remove the capacitor aluminum shell. This reduces the convenience of removing the stamped capacitor aluminum shell and improves the stamping efficiency of the capacitor aluminum shell.
[0032] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5 The bottom end of the fixing plate 6 is provided with a convex groove 16, and the top end of the punch 2 is fixedly connected with a convex seat 17. The convex seat 17 and the convex groove 16 are slidably engaged, which facilitates the replacement of the punch 2. The fixing plate 6 is threaded with a first screw 18 that mates with the convex seat 17, which facilitates the fixing of the convex seat 17. The top end of the fixing seat 10 is provided with two slots 19, and the bottom end of the die 3 is fixedly connected with two sockets 20. The two sockets 20 are respectively inserted into the two slots 19, which facilitates the disassembly and replacement of the die 3. The fixing seat 10 is threaded with a second screw 21 that mates with the sockets 20, which facilitates the fixing of the sockets 20.
[0033] Specifically, since the punch 2 is connected to the fixed plate 6 through the punch seat 17, and the die 3 is inserted into the slot 19 through the socket 20 and connected to the fixed seat 10, the punch 2 and the die 3 can be fixed by tightening the first screw 18 and the second screw 21 respectively, thus facilitating the replacement of the punch 2 and the die 3.
[0034] Please see Figure 1 and Figure 2 A first electric cylinder 22 is fixedly connected to the left and right sides of the fixed base 10 on the fixed frame 4. A side positioning plate 23 is fixedly connected to the telescopic end of the first electric cylinder 22, which plays a positioning role on the side end of the stamped capacitor aluminum shell plate. Two first sliding rods 24 are fixedly connected to the side positioning plate 23. Both first sliding rods 24 are slidably engaged with the fixed frame 4, which plays a supporting role on the side positioning plate 23. A connecting plate 25 is fixedly connected to the rear end of the fixed frame 4. A second electric cylinder 26 is fixedly connected to the front end of the connecting plate 25. A rear positioning plate 27 is fixedly connected to the telescopic end of the second electric cylinder 26. Two second sliding rods 28 are fixedly connected to the rear positioning plate 27. Both second sliding rods 28 are slidably engaged with the connecting plate 25, which facilitates the positioning of the rear end of the stamped capacitor aluminum shell plate.
[0035] Specifically, the first electric cylinder 22 pushes the side positioning plate 23 to move, and the second electric cylinder 26 drives the rear positioning plate 27 to move. According to the size of the sheet metal for stamping the aluminum shell of the capacitor, the two side positioning plates 23 and the rear positioning plate 27 are adjusted to the appropriate positions. The two side positioning plates 23 and the rear positioning plate 27 facilitate the positioning of the sheet metal required for stamping the aluminum shell of the capacitor, which makes it easier for people to place the sheet metal quickly, saves the time of the staff to place the sheet metal, and improves the efficiency of stamping the aluminum shell of the capacitor.
[0036] In summary, when using the overall equipment:
[0037] The first electric cylinder 22 pushes the side positioning plate 23 to move, and the second electric cylinder 26 drives the rear positioning plate 27 to move. The two side positioning plates 23 and the rear positioning plate 27 are adjusted to suitable positions according to the size of the aluminum plate for stamping the capacitor shell. Then, the required aluminum plate for stamping the capacitor shell is placed on the die 3, positioned between the two side positioning plates 23 and the rear positioning plate 27, with the side ends of the plate in contact with the side ends of the two side positioning plates 23 and the rear positioning plate 27. Then, the two second hydraulic cylinders 7 push the pusher plate 8 down to a position close to the side positioning plate 23. Then, the first hydraulic cylinder 5 pushes the fixing plate 6 and the punch 2 downwards. The punch 2 and the die... The plate is stamped by the cooperation of the 3, and the plate is stamped into the shape of a capacitor aluminum shell. After the stamping is completed, the first hydraulic cylinder 5 pulls the fixed plate 6 and the punch 2 to move upward. If the capacitor aluminum shell is stuck outside the punch 2, the push plate 8 pushes the capacitor aluminum shell outside the punch 2 down. When the punch 2 moves to the uppermost side, the two second hydraulic cylinders 7 push the push plate 8 to the uppermost side. If the capacitor aluminum shell is stuck inside the punch 2, the third hydraulic cylinder 12 pushes the slide plate 13 and the two top plates 14 to move upward. The two top plates 14 push against the sides of the capacitor aluminum shell and push the capacitor aluminum shell out from inside the die 3. Then people can take away the stamped capacitor aluminum shell.
