Description

Technical field

[0001] The utility model belongs to the technical field of a trimming machine key device in a trimming process of an automobile piston ring, and particularly relates to a trimming machine key for a piston ring. [Background Technology]

[0002] The piston ring is a core component in automobile engines. It operates at high speeds in harsh environments such as high temperature, high pressure, alternating loads, and poor lubrication conditions. In addition to being used in automobile internal combustion engine mainframes, the piston rings of vehicles currently in use on the market are also frequently replaced, resulting in a large market demand for piston rings. Looking at manufacturers, their goal, in addition to minimizing costs and maximizing efficiency, is ease of operation. Regarding the piston ring trimming process, the traditional trimming device is to install a trimming key within the trimming die sleeve of the trimming machine. The guide keys of the old trimming key are the same width at the top and bottom. This method of guiding material is not conducive to the entry of the piston ring opening. Not only does it fail to guide the material, it is also prone to ring breakage. Since the piston ring itself has a certain degree of elasticity, when the piston ring breaks at this point, it is easy to cause injuries. This not only delays production, but also reduces the yield rate and increases production costs.

[0003] In order to overcome the above technical problems, after a long period of observation and research, the applicant discloses a piston ring cutting machine cutting key. [Utility Model Content]

[0004] The purpose of the utility model is to provide a piston ring trimming machine trimming key to solve the problems raised in the above background technology.

[0007] Preferably, the width of the back plate 4 is smaller than the width of the left side of the boss 1 , and the vertical height of the back plate 4 is greater than the vertical height of the boss 1 .

[0008] Preferably, the width of the guide key 3 is smaller than the width of the left side of the back panel 4 .

[0009] Preferably, the guide key 3 and the bottom of the back plate 4 are designed to be inclined structures, and the angle between the inclined surface and the horizontal plane is 60°.

[0010] Preferably, the upper end surfaces of the boss 1, the back plate 4 and the guide key 3 are in the same plane.

[0011] Preferably, the angle between the two side surfaces of the guide key 3 and the center line is 1°30′.
