Abstract

The invention relates to the field of air spring manufacturing. A universal curling tool for an air spring comprises an oil press, a lower die assembly, a triangular wedge block, a split pin, a bivalve setting ear die, an air spring positioning assembly and an upper die assembly. The upper die assembly and the lower die assembly are respectively arranged on an upper die fixed plate and a lower die fixed plate of the oil press; the triangular wedge block is arranged on an oil press bottom plate; and the bivalve setting ear die is connected onto the triangular wedge block by the split pin. A universal curling method for the air spring comprise the following steps of die setting, ear die assembly, integral die assembly curling, die sinking and pickup. According to the universal curling tool and the universal curling method for the air spring disclosed by the invention, by the integrated design of various mechanisms, the equipment input cost is reduced, the operation is convenient, the danger is reduced, the potential safety hazard is eliminated, the efficiency is improved, the labor strength of an operator is reduced, and enough space is also provided for realizing automatic product pickup and placement during the curling process of the air spring.

Description

[0001] technical field [0002] The invention relates to the field of air spring manufacturing, in particular to an air spring crimping tool and a crimping method. Background technique [0003] Air spring refers to a spring that is filled with compressed air in a retractable airtight container and utilizes the elastic action of air. Rolling is a molded flanging deformation processing method that is shaped by a mold. [0004] As a product with excellent shock absorption performance, air springs are being widely used in rail vehicles and high-end automobile shock absorption systems. The curling process of air springs is an assembly process in the production process of air springs. By using the molded flanging method, the edge clasp of the rubber airbag body is crimped and wrapped on the metal bottom plate (curling plate), so as to realize the airtight combination of the metal bottom plate (curling plate) and the rubber airbag body. [0005] The assembly process of the rubbe...
