Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, and particularly relates to a stamping die for spring production with a shock-absorbing structure. Background Technique

[0002] The nitrogen spring, also known as a nitrogen cylinder, utilizes the principle of an accumulator to control the up and down movement of a balance cylinder in cooperation with the servo motor of the main spindle head to balance the weight of the main spindle head, so as to achieve high-speed and high-precision machining. Its structure generally includes a spring retaining ring, a sealing ring, a plunger, a cylinder block, a bushing, a guide ring, a dust sealing ring, etc. The nitrogen spring sealing ring, as the main component of the nitrogen spring, mainly serves the purpose of sealing to prevent nitrogen leakage. Its structure is generally an O-ring. When producing the nitrogen spring sealing ring, a stamping die is usually used to stamp it into shape.

[0003] In the prior art, there is a stamping die for O-ring production with the publication number of CN214819208U. In this stamping die for O-ring production, through the setting of a jacking member, when the upper die moves downward, the bottom of the upper die will contact the top of the jacking plate, and the jacking plate will drive the moving plate to move downward through a connecting rod, transmitting the acting force to the compression spring. The compression spring can provide a buffering effect, converting the rigid contact between the upper die and the lower die into an elastic contact, reducing the damage to the lower die.

[0004] However, after the nitrogen spring sealing ring is stamped, it is not convenient to take out and collect the nitrogen spring sealing ring from the lower die, which has certain limitations. Therefore, it is necessary to design a stamping die for spring production with a shock-absorbing structure to solve the above problems.

[0005] The information disclosed in this background technical section is only intended to enhance the overall understanding of the utility model and should not be regarded as an admission or any form of implication that this information constitutes prior art already known to those of ordinary skill in the art.
