Abstract
Description
Technical Field
[0001] This utility model relates to the field of disc springs, and in particular to a stamping device for processing disc springs. Background Technology
[0002] Disc springs, also known as Belleville spring washers, are conical discs that can be used individually, in series, or in parallel. They bear static or dynamic loads along the axial direction at the upper inner edge and lower outer edge. When compressed, they deform until they are flattened, storing energy as a live load. When necessary, they automatically convert into additional compressive loads required for sealing, thereby reducing the continuous tightening requirements of gaskets and packings.
[0003] In the stamping process of disc spring processing, the circular structure of the disc spring causes it to tend to bounce upwards when subjected to stamping pressure due to uneven force distribution. This bounce is extremely dangerous and may cause accidental injury to operators, greatly reducing the safety of disc spring stamping operations. At the same time, disc spring stamping relies on repeated impact forming. During this process, mechanical energy is converted into heat energy, and the internal temperature of the disc spring will continue to rise. The disc spring becomes soft at high temperature and may stick to the stamping die, making unloading extremely difficult. Traditional methods often require the use of tools to remove the disc spring, which is not only time-consuming but also inconvenient to operate, significantly reducing the unloading efficiency of disc springs and affecting the overall production progress. Therefore, a stamping device for disc spring processing is proposed to solve the above problems. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a stamping device for disc spring processing, which aims to improve the safety problems caused by the spring bouncing during disc spring stamping, as well as the problems of difficulty in high-temperature material cutting and low efficiency in the prior art, and to ensure the safe and efficient operation of the disc spring processing process.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Reference Figure 1-4This utility model provides an embodiment of a stamping device for processing disc springs, including a lower base plate 1, an upper top plate 2 on the top of the lower base plate 1, connecting rods 3 fixedly installed at the four corners of the bottom of the upper top plate 2, the bottom of the connecting rods 3 being fixedly installed to the top of the lower base plate 1, a protective cover 4 fixedly installed at the bottom of the upper top plate 2, an electric push rod 5 fixedly installed at the top of the inner wall of the protective cover 4, the telescopic end of the electric push rod 5 penetrating to the bottom of the protective cover 4 and fixedly installed with a stamping block 6, and a stamping block 6 being fixedly installed at the top of the lower base plate 1. The limiting component 7 is used to limit the disc spring. The top of the lower base plate 1 is provided with an ejection component 8 to facilitate the discharge of the disc spring. First, the disc spring to be stamped can be placed on the lower base plate 1. Then, the limiting component 7 can limit the disc spring. Then, the electric push rod 5 can be activated. The telescopic end of the electric push rod 5 drives the stamping block 6 to move to the bottom. The movement of the stamping block 6 to the bottom can stamp the disc spring on the lower base plate 1. After the disc spring is stamped, the stamped disc spring can be ejected by the ejection component 8.
[0030] Reference Figure 1-4 The limiting component 7 includes a first retaining ring 71 and a second retaining ring 72. The second retaining ring 72 is located to the right of the first retaining ring 71. A connecting block 73 is fixedly installed on the left side of the first retaining ring 71 and the right side of the second retaining ring 72. Connecting grooves 74 are provided on both sides of the top of the lower base plate 1. The connecting block 73 and the connecting groove 74 are slidably installed. Through the cooperation of the first retaining ring 71, the second retaining ring 72, the connecting block 73 and the connecting groove 74, the disc spring to be stamped can be placed on the top of the lower base plate 1. Then, the first retaining ring 71 can be pushed to the right, and then the second retaining ring 72 can be pushed to the left. At this time, the disc spring can be limited, and then it can be stamped to prevent it from shaking. Fixing blocks 75 are fixedly installed on both sides of the top of the lower base plate 1. The outer side of the fixing block 75 is connected by... A screw 76 is rotatably mounted on the bearing. The outer end of the screw 76 extends through the outer side of the fixing block 75 and is threaded onto the fixing block 75. Through the cooperation between the fixing block 75 and the screw 76, rotating the screw 76 can drive the connecting block 73 to move inward. The movement of the fixing block 75 inward drives the first retaining ring 71 and the second retaining ring 72 to move towards each other simultaneously, thereby stabilizing and limiting the movement of the disc spring. A circular block 9 is fixedly mounted on the outer end of the screw 76, and a handle 10 is fixedly mounted on the outer side of the circular block 9. Through the cooperation between the circular block 9 and the handle 10, rotating the handle 10 can drive the circular block 9 to rotate, and the rotation of the circular block 9 can drive the screw 76 to rotate, thereby increasing the contact area when rotating the handle 10 and improving the rotation efficiency of the screw 76.
[0031] Reference Figure 1-4The ejector assembly 8 includes a sleeve 81, inside which a disc 82 is slidably mounted, and inside which a baffle 83 is fixedly mounted, and at the bottom of the inner wall of the sleeve 81 a spring 84 is fixedly mounted, with the top of the spring 84 fixedly mounted to the bottom of the disc 82. Through the cooperation of the sleeve 81, disc 82, baffle 83 and spring 84, when the disc spring is being stamped, the disc 82 moves to the bottom and compresses the spring 84. When the bottom of the disc 82 contacts the top of the baffle 83, the disc spring can be stamped. After the stamping is completed and the stamping block 6 separates from the disc spring, the disc spring can be ejected under the action of the spring 84. Limiting blocks 85 are fixedly installed on the front and rear sides of the top of the sleeve 81. The bottom of the limiting block 85 contacts the bottom of the inner wall of the disc 82. The limiting block 85 and the disc 82 are on the same plane. By setting the limiting block 85, the disc 82 can be limited to prevent the spring force of the spring 84 from being too large, which would cause the disc 82 to separate from the sleeve 81. Four sets of limiting rods 86 are fixedly installed on the bottom of the disc 82. The bottom of the limiting rods 86 extends through to the bottom of the baffle 83 and slides with the baffle 83. By setting the limiting rods 86, the disc 82 can be limited to prevent the disc 82 from separating from the baffle 83 when it moves, which would cause the disc spring to be unstable.
[0032] Working principle: First, place the disc spring to be stamped on top of the sleeve 81. Then, rotate the handle 10. Since the handle 10 is connected to the circular block 9, the rotation of the handle 10 will cause the circular block 9 to rotate as well. The circular block 9 is connected to the screw 76, and the rotation of the circular block 9 will in turn cause the screw 76 to rotate. The screw 76 and the connecting block 73 are connected by a thread. When the screw 76 rotates, the connecting block 73 will move inward under its action. The fixing block 75 on the connecting block 73 will also move inward. The fixing block 75 is connected to the first retaining ring 71 and the second retaining ring 72 respectively. This will cause the first retaining ring 71 and the second retaining ring 72 to move towards each other at the same time, thereby achieving stable limiting of the disc spring and preventing it from displaced during the stamping process. When the disc spring is limited... Then, the electric push rod 5 is activated. The telescopic end of the electric push rod 5 extends downward, driving the stamping block 6 to move to the bottom. During the downward movement of the stamping block 6, it applies pressure to the disc spring placed on the disc 82 for stamping. At this time, the disc 82 located below the disc spring will move to the bottom due to the pressure transmitted by the disc spring. A spring 84 is connected below the disc 82. The downward movement of the disc 82 will compress the spring 84. When the bottom of the disc 82 contacts the top of the baffle 83, it means that the disc spring has reached the appropriate stamping position and the stamping operation is completed. When the stamping of the disc spring is finished, the electric push rod 5 drives the stamping block 6 to rise, causing it to disengage from the disc spring. At this time, under the action of the elastic restoring force of the compressed spring 84, the spring 84 will extend upward, thereby pushing out the disc spring for removal or subsequent operation.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
