[0011] The application can be further configured to further include a stacking step before the storage step, the stacking step being used for stacking the finished product on a fixed column to a preset height, limiting the top finished product, vertically arranging the bays from top to bottom, and inverting the sleeve in the storage step so that the sleeve opening faces downward, and gradually moving downward so that the finished product enters the sleeve.

[0012] By adopting the above technical scheme, the bayonet can make the disc spring rotate when the sleeve moves downward, so that the disc spring is placed in the sleeve more conveniently.

[0013] The application can be further configured to place the sealing plate at the bottom in the stacking step, and place the finished product above the sealing plate, wherein the diameter of the sealing plate is greater than the inner diameter of the sleeve, and the edge of the sealing plate is deformable.

[0014] By adopting the above technical scheme, the sealing plate can block the sleeve when moving to the bottom, so that the disc spring is stored.

[0015] The application can be further configured to provide a support plate on the fixed column, the support plate being fixedly connected with the fixed column, the diameter of the support plate being smaller than the diameter of the sealing plate, and the support plate being used for supporting the sealing plate.

[0016] By adopting the above technical scheme, the support plate can facilitate the sealing plate to enter the sleeve.

[0017] The application can be further configured to further include a stacking step before the storage step, the stacking step being used for stacking the finished product on the fixed column to a preset height, limiting the top finished product, vertically arranging the bays from top to bottom, and inverting the sleeve in the storage step so that the sleeve opening faces upward, moving the fixed rod so that the finished product moves above the sleeve, and the bay corresponds to the bayonet, and then removing the limitation so that the finished product is in the sleeve.

[0018] The application can be further configured to limit the stuck finished product and reset the fixed column when the finished product is stuck.

[0019] By adopting the above technical scheme, when the finished product is stored, the finished product is moved to the upper side of the sleeve, and is moved downward into the sleeve, and when the finished product is stuck, the stuck finished product is limited, so that the stuck finished product is removed.

[0025] The present application discloses a composite disc spring, comprising a body and a sleeve, a rubber layer is arranged on the body, a clamping opening is arranged on the body and the rubber layer, a clamping strip 1 adapted to the clamping opening is arranged on the sleeve, the clamping strip 1 is spirally arranged, the clamping strip 1 is not deformable, an elastic layer is arranged on the inner layer of the sleeve, the clamping strip 1 is fixedly connected to the elastic layer, and the elastic layer is made of rubber. Figure 1 , a schematic diagram of the internal side wall of the sleeve after the sleeve is unfolded along the axis.

[0026] The present application also discloses a mold for producing a composite disc spring, which is used for producing a body in a composite disc spring, comprising an upper mold and a lower mold, an upper cavity is arranged on the upper mold, a lower cavity is arranged on the lower mold, a positioning protrusion is arranged in the upper cavity and the lower cavity, and the positioning protrusion is used for accommodating the clamping opening.

[0027] Referring to references 2-3, this application also discloses a method for producing a composite disc spring, comprising the following steps: a forming step, processing the material to form a blank with a snap-fit ​​on its outer edge; a grinding step, grinding the edge of the blank; a composite step, composite the ground blank with a rubber layer; a finishing step, grinding or cutting the composite product to obtain the finished product; a stacking step, placing the finished product on a fixed post 2 and stacking them vertically from top to bottom with snap-fit ​​on the upper edge. In the stacking step, a support plate 3 is fixedly connected to the fixed post 2, and a sealing plate is also fitted on the fixed post 2. The diameter of the sealing plate is larger than the diameter of the support plate 3 and is supported by the support plate 3. The edge of the sealing plate is deformable (e.g., made of rubber) and its diameter is larger than the inner diameter of the sleeve; a storage step, inverting the sleeve so that the opening of the sleeve faces downward and gradually moving it downward so that the finished product enters the sleeve until the sealing plate also enters the sleeve. At this time, the edge of the sealing plate abuts against the inner wall of the sleeve, thereby sealing the sleeve.

[0028] In another embodiment, a limiting member 22 is provided at the top of the fixing column 2. In this embodiment, the limiting member 22 is a rubber layer. An air vent 21 is provided on the side wall of the fixing column 2. The portion of the limiting member 22 located at the upper and lower ends of the air vent 21 is fixedly connected to the fixing column 2, while the middle portion is not connected to the fixing column 2 and covers the air vent 21. After the finished product is placed on the fixing column 2 and stacked to a preset height, the top of the finished product is limited by introducing pressurized gas into the air vent 21, causing the rubber layer to deform, thereby limiting the finished product. With the sleeve opening facing upward, the fixing rod is moved, causing the finished product to move above the sleeve and then downward, with the latch and the locking strip 1 corresponding. Then, the limiting is released, and the finished product is placed inside the sleeve. When a finished product is stuck, the stuck finished product is limited, and the fixing column 2 is reset to remove the stuck finished product. When the finished product is stuck at the end of the clip 1, the fixing rod is moved upward, causing the unstuck finished product to fall off the fixing rod and into the sleeve. This causes the rubber layer to deform, limiting the stuck finished product. Then the fixing rod is moved, making it easier to remove the stuck finished product.

[0029] The implementation principle of this embodiment is as follows: When in use, the user can select the appropriate number of disc springs and the appropriate sleeve length (for example, by cutting to obtain the appropriate sleeve length) to make it more applicable.
