Description

Technical Field

[0001] The utility model relates to the technical field of material pressing mechanisms, in particular to an antimony-free friction-reducing material pressing mechanism. Background Art

[0002] Anti-friction materials are mainly used to make various sliding bearings. These materials have the characteristics of low friction coefficient and good wear resistance, and can reduce the friction between the contact parts of various machines. One of the main uses of anti-friction materials is to prevent adhesion between the contact surfaces of parts during the operation of the machine. There are many varieties of anti-friction materials, including many different types. However, all these metal-based materials can be divided into two categories, namely cast anti-friction materials and materials made by powder metallurgy.

[0003] When it is in use, during the processing of the anti-friction material, a pressure plate is required to be arranged above it to press it, so that the anti-friction material is not easy to slip or shift during the processing.
