Description

Technical Field

[0002] Gas spring is an industrial accessory that can perform support, buffer, brake, height adjustment and angle adjustment functions. It consists of the following parts: pressure cylinder, piston rod, piston, sealing guide sleeve, filler (inert gas or oil-gas mixture), cylinder control element and cylinder control element (referring to controllable gas spring) and joints, etc. In the process of producing and processing gas springs, it is necessary to perform a sealing process on one end of the piston rod. When performing the sealing process, the electromagnetic heating coil will first be used to quickly heat one end of the piston rod, and then the tooling will be used to immediately seal the heated end of the piston rod. However, the general sealing machine uses manual placement and removal of the piston rod.
