The disclosed solution cannot increase or decrease a single disc spring according to actual needs. Summary of the invention

[0003] In view of the shortcomings of the prior art, one of the purposes of the present application is to provide a composite disc spring, a production mold and a production method, which have the advantage of facilitating the addition and removal of individual disc springs when stacked for use.

[0004] The above-mentioned purpose of the present application is achieved through the following technical solutions:

[0005] A composite disc spring comprises a body and a sleeve. The body is provided with a rubber layer, the body and the rubber layer are both provided with bayonet holes, and the sleeve is provided with a clamping strip matched with the bayonet hole.

[0006] By adopting the above technical solution, the number of disc springs can be set according to needs during use, thereby making it more applicable. At the same time, the presence of the clamping strip makes the disc spring more stable.

[0007] In a preferred example, the present application can be further configured as follows: the clamping strip is spirally arranged, the clamping strip cannot be deformed, the inner layer of the sleeve is provided with an elastic layer, and the clamping strip is fixedly connected to the elastic layer.

[0008] By adopting the above technical solution, the spirally arranged clamping strip can reduce the probability of displacement of the disc spring. At the same time, the existence of the elastic layer allows deformation space when the disc spring is deformed under force.

[0009] The present application also discloses a composite disc spring production mold, which is used to produce the main body of the above-mentioned composite disc spring, including an upper mold and a lower mold, the upper mold is provided with an upper cavity, the lower mold is provided with a lower cavity, and positioning protrusions are provided in the upper cavity and the lower cavity for accommodating the bayonet.

[0010] The present application also discloses a method for producing a composite disc spring, including a molding step of processing a material to form a blank having a snap fit on an outer edge; a grinding step of grinding the edge of the blank; a compounding step of compounding a rubber layer on the ground blank; a finishing step of finishing the compounded product to obtain a finished product; and a storage step of placing the finished product into a sleeve.

[0011] In a preferred example, the present application can be further configured as follows: before the storage step, it also includes a stacking step, in which the finished products are stacked on fixed columns, and the bayonet is arranged vertically from top to bottom. In the storage step, the sleeve is inverted so that the sleeve opening is downward, and gradually moved downward to allow the finished product to enter the sleeve.

[0012] By adopting the above technical solution, when the sleeve moves downward, the presence of the clamping strip will cause the disc spring to rotate, thereby making it more convenient to place the disc spring in the sleeve.

[0013] In a preferred example, the present application can be further configured as follows: in the stacking step, the sealing plate is placed at the bottom, and the finished products are placed above the sealing plate. The diameter of the sealing plate is larger than the inner diameter of the sleeve, and the edge of the sealing plate can be deformed.

[0014] By adopting the above technical solution, the existence of the sealing plate enables the sealing plate to seal the sleeve when it moves to the bottom, thereby realizing the storage of the disc spring.

[0015] In a preferred example, the present application can be further configured as follows: a support plate is provided on the fixed column, the support plate and the fixed column are fixedly connected, the diameter of the support plate is smaller than the diameter of the sealing plate, and the support plate is used to support the sealing plate.

[0016] By adopting the above technical solution, the presence of the support plate makes it easier for the sealing plate to enter the sleeve.

[0017] In a preferred example, the present application can be further configured as follows: before the storage step, it also includes a stacking step. In the stacking step, the finished product is placed on the fixed column and stacked to a preset height, and the finished product at the top is limited, and the bayonet is arranged vertically from top to bottom. In the storage step, the sleeve opens upward, and the fixing rod is transferred so that the finished product moves to the top of the sleeve, and the bayonet and the card strip correspond to each other, and then the limit is cancelled so that the finished product is located in the sleeve.

[0018] In a preferred example, the present application can be further configured as follows: when a finished product is stuck, the stuck finished product is limited, the fixing column is reset, and the stuck finished product is removed.

[0019] By adopting the above technical solution, when storing finished products with higher precision requirements, the finished products are moved to the top of the sleeve and moved downward into the sleeve. When a jam occurs, the jammed finished products are limited, thereby facilitating the removal of the jammed finished products. BRIEF DESCRIPTION OF THE DRAWINGS
