Embodiment Construction

[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0039] see Figure 1 to Figure 3 , a piston forming method of a rubber air spring, comprising the following steps:

[0040] In step S101, stamping the metal sheet to form a cylindrical portion 10, one end of the cylindrical portion 10 is protruded with an operating convex portion 11, and the end of the cylindrical portion 10 facing away from the operating convex portion 11 is an open end; For example, the operation convex portion 11 is formed by impact while forming the cylindrical portion 10 by impacting a sheet metal material.

[0041] In step S102, the cylindrical part 10 is turned over so that the open end faces a first mold (not shown in the figure), and a first cavity is formed on the first mold, and the diameter of the first cavity is along the The direction away from the cylindrical portion 10 gradually decreases;

[0042] In step S103, the cylindr...

Abstract

The invention relates to a method for forming a piston of a rubber air spring, and belongs to the field of rubber air spring manufacturing. The method for forming the piston of the rubber air spring comprises the following step of punching a metal plate to form a cylindrical part, wherein an operation convex part is convexly arranged at one end of the cylindrical part, and the end, away from the operation convex part, of the cylindrical part is an open end; turning over the cylindrical part so as to enable the open end to face a first die, wherein a first cavity is formed in the first die, andthe diameter of the first cavity is gradually reduced in the direction away from the cylindrical part; and driving the cylindrical part to move towards the first die, wherein the periphery of the cylindrical part is pressed against the circumferential surface of the first cavity to force the periphery of the cylindrical part to be bent inwards to be deformed. The piston forming method is convenient for forming a cylindrical piston.

Description

technical field [0001] The invention relates to the technical field of forming metal parts, more specifically, it relates to a piston forming method of a rubber air spring. Background technique [0002] The rubber air spring is a kind of elastic component. By filling the air spring with compressed air, the compressibility of the air is used to realize the elastic effect. The rubber air spring has many characteristics of superior metal springs: the rubber air spring has nonlinear characteristics, and its characteristic line can be designed as an ideal curve according to the needs; the stiffness of the rubber air spring changes with the load, so that the spring device has an ideal Features: The rubber air spring can bear axial and radial loads at the same time, and can also transmit torque: The rubber air spring can obtain different load-bearing capacities by adjusting the internal pressure. [0003] For example, Chinese Invention Patent Publication No. CN107218329A discloses...
