Description

Technical Field

[0001] The utility model relates to the technical field of forging presses, in particular to a forging press for processing disc springs. Background Technique

[0002] A disc spring is a washer-shaped spring with a conical cross-section, which is used to bear static or dynamic loads and is suitable for machinery or dies with small installation space but large loads. It is in the shape of a conical disc and can be used either individually or in series or parallel combinations. It bears static or dynamic loads acting axially at the upper inner edge and lower outer edge, and deforms after being compressed until it is flattened to store energy in the form of live load. When necessary, it automatically converts into the additional compression load required for sealing to reduce the continuous requirement for tightening in the use of gaskets and packings.

[0003] Disc springs are generally produced by stamping with a forging press. For example, a disc spring stamping device proposed in the patent publication number CN212494850U includes a base, on which a lower die holder is fixedly connected. Above the lower die holder, an upper die holder is connected to the base. An upper die base is fixed to the lower side of the upper die holder. An upper die cavity is provided in the upper die base, and a concave die is fixed in the upper die cavity. A punch that can move up and down is connected in the concave die. A lower die base is fixedly connected to the lower die holder. A stripping die with the same shape as the concave die is connected in the lower die base. The stripping die can move up and down and can automatically reset. A connection cavity is provided on the stripping die. A convex-concave die is connected in the lower die base. The convex-concave die extends upward into the connection cavity and can automatically reset. In the natural state, the lower sides of the punch and the concave die are flush, and the upper side of the convex-concave die is lower than the upper side of the stripping die. When the punch moves upward and there is no external force, the punch automatically resets to the natural state. After the existing disc spring stamping device stamps the disc spring, workers need to take the stamped disc spring and the round pieces generated by punching from the die, and then place a new round thin sheet into the die for the next stamping. Workers also need to place the disc spring and the round pieces separately, which affects the processing efficiency of the disc spring. Therefore, we provide a forging press for processing disc springs. Content of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] Please refer to Figures 1 to 3, the present utility model provides a technical solution: a forging press for processing disc springs, including a press body 1, a punching head 2 and a support table 10 installed on the press body 1. The support table 10 is located in the front of the press body 1, and the punching head 2 is located directly above the support table 10. An upper punching hole 3 is opened at the bottom of the punching head 2, and a conveying pipe 4 is connected to the rear side of the top end of the upper punching hole 3. By setting the conveying pipe 4, when processing the disc spring, the round piece generated by punching will be stabbed into the upper punching hole 3 by the punching column 13, and then the round piece will be sucked into the first storage box 5 along the conveying pipe 4, eliminating the need for manual handling of the round piece and improving the production efficiency of the disc spring. The end of the conveying pipe 4 far from the upper punching hole 3 is connected to the first storage box 5. A negative pressure pump 6 is installed on the top of the first storage box 5. By setting the negative pressure pump 6, the air inside the first storage box 5 is pumped out by the negative pressure pump 6, enabling a negative pressure to be formed inside the first storage box 5. The first storage box 5 is installed inside the press body 1, and a discharge port 7 is opened at the rear of the first storage box 5. A sealing cover plate 8 for sealing the discharge port 7 is arranged at the rear of the first storage box 5. By setting the sealing cover plate 8, after the processing of the disc spring is completed, the sealing cover plate 8 can be removed to take out the round pieces inside the first storage box 5. The sealing cover plate 8 is fixed to the first storage box 5 by fastening bolts 9 connected in a threaded manner.

[0024] Please refer to Figures 4 to 5 , a lower die 11 is installed on the top of the support table 10. A placement hole 12 is opened at the top of the lower die 11, and a punching column 13 is arranged in the middle of the placement hole 12. By setting the punching column 13, when the punching head 2 presses downward on the circular thin sheet, the punching column 13 is inserted into the inside of the upper punching hole 3 to punch the circular thin sheet. The placement hole 12 is located directly below the punching head 2 and matches the punching head 2. The punching column 13 matches the upper punching hole 3. A compression spring 14 is fixedly connected inside the placement hole 12. The compression spring 14 is sleeved outside the punching column 13. The top of the compression spring 14 is fixedly connected to a top-out elastic sheet 15. By setting the top-out elastic sheet 15, after punching the disc spring, the upward elastic force given by the compression spring 14 to the top-out elastic sheet 15 can be used to push the punched disc spring upward, facilitating the discharge of the disc spring.

[0025] Please refer to Figure 1 , Figure 4 , Figure 5, a blowing port 16 is provided on the left side of the placing hole 12, a blanking chute 18 is provided on the right side of the placing hole 12, a through hole for the transmission of the punching column 13 is provided in the middle of the ejecting spring piece 15, the top of the ejecting spring piece 15 is flush with the left end of the blanking chute 18, and a high-pressure blower 17 is installed on the left side of the lower die 11. By setting the high-pressure blower 17 and using the high-pressure blower 17 to blow high-pressure air to the right, the disc spring can be blown to move to the right, so that the disc spring slides into the blanking chute 18. The air outlet of the high-pressure blower 17 is communicated with the blowing port 16. A collection box 19 is installed on the top of the support table 10, and the collection box 19 is placed at the bottom of the right end of the blanking chute 18. By setting the blanking chute 18 and using the high-pressure blower 17 to blow the disc spring into the blanking chute 18, the disc spring automatically slides into the collection box 19 along the blanking chute 18 without manual taking, which greatly improves the production efficiency of the disc spring.

[0026] In summary, when the forging press for processing the disc spring is in use, the circular sheet with holes is placed into the placing hole 12, and then the punching head 2 punches down on the circular sheet. At this time, the punching column 13 pokes the circular sheet generated by punching into the upper punching hole 3. The air in the first storage box 5 is pumped out by the negative pressure pump 6 to generate negative pressure, and the circular sheet is sucked into the first storage box 5. Then the punching head 2 is lifted upward, and the ejecting spring piece 15 is given an upward elastic force by the compression spring 14, which can push the punched disc spring to a position flush with the blanking chute 18. The high-pressure blower 17 blows air to the disc spring through the blowing port 16, so as to blow the disc spring into the blanking chute 18, and the disc spring slides down along the blanking chute 18 into the collection box 19, and that's it.

[0027] It should be noted that the negative pressure pump 6 and the high-pressure blower 17 used in the present invention are both existing technical products, and those skilled in the art can select according to needs, and no special limitation is made here.
