Riveting die of floating pressure head structure

Abstract

The invention discloses a riveting die of a floating pressure head structure. An upper oil groove of the die is connected with an upper template of the die, an upper base plate is arranged between the upper template and the upper oil groove, and a closed space is formed between the upper base plate and the upper oil groove through a sealing gasket. The upper template is connected with a lower template through guide pillars and guide sleeves, upper pressure heads are arranged above the upper oil groove, and lower pressure heads are arranged below a pressure head fixing plate and connected with a prepressing plate. The upper pressure heads and the lower pressure heads are oppositely arranged, the pressure head fixing plate is connected with the lower template, a lower oil groove is formed between the pressure head fixing plate and the lower template, and a closed space is formed between the pressure head fixing plate and the lower oil groove through a sealing gasket. The closed space formed between the upper base plate and the upper oil groove and the closed space formed between the pressure head fixing plate and the lower template are filled with hydraulic oil. According to the hydraulic principle, it is ensured that equal pressure is exerted on both the pressure heads in the riveting process, the die technology can meet the machining requirement and the assembling requirement, all rivets can have high riveting quality in the riveting process, and the riveting die is suitable for all types of multi-pressure-head riveting dies.

Description

technical field [0001] The invention relates to a riveting die, in particular to a riveting die with a floating head and pressing head structure. Background technique [0002] At present, dozens of rivets need to be riveted at the same time when riveting the friction plate of the automobile clutch driven disc. Since the indenter of the riveting die is fixed, the plane of each indenter is on the same plane, and the rivet that needs to be riveted Dozens of rivets cannot be riveted tightly due to the dimensional error of each part. This kind of problem is often encountered in production, which seriously affects the use and life of the product. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiency of the fixed riveting head die, and provide a riveting die with a floating head structure that uses hydraulic technology to meet processing and assembly requirements and can ensure reliable riveting of each rivet during the riveting pro...
