Crimping machine

Abstract

The invention relates to a crimping machine. The machine comprises at least two dies used for crimping a pipe fitting, mounting bases, an adjusting assembly, a front die and a rear die. The dies are evenly distributed in the circumferential direction of the pipe fitting, the dies are fan-shaped, and all the dies are spliced into a cylinder with the inner diameter; and the mounting bases are arranged corresponding to the dies, each mounting base is detachably connected with the dies through a dismounting assembly, all the mounting bases define a mounting assembly, and when the dismounting assembly moves in the radial direction of the mounting bases, the mounting bases and the dies are in a movable state, and the adjusting assembly is used for tensioning the mounting bases and adjusting the positions of the mounting bases. The front die is matched with the front part of the mounting assembly; and the rear die is matched with the rear part of the mounting assembly; and the front part and the rear part of the mounting assembly are cones. According to the crimping machine provided by the invention, the roundness error of the crimped pipe fitting is small, the assembly and the use of the pipe fitting are not influenced, and meanwhile, when pipe fittings with different diameters need to be crimped, the dies are convenient and rapid to replace.

Description

technical field [0001] The invention relates to the technical field of crimping machine manufacturing, in particular to a crimping machine. Background technique [0002] The crimping machine is a kind of hydraulic equipment for crimping the pipe fitting assembly. It applies contraction force to the matching metal joint through the mold of the crimping machine, and firmly crimps the metal joint on the matching high-pressure oil pipe for construction machinery or the brake pipe on the car. , oil pipe, air conditioning pipe, power pipe. The crimping machine is suitable for the crimping of various mechanical high and low pressure oil pipes, air pipes, water pipes, cable joints, automobile air conditioning pipes, automobile power steering pipes, engine oil pipes, automobile oil supply pipes, building accessories, and daily hot water pipes. It is widely used in Vehicles, construction machinery, hydraulic machinery, welding and cutting equipment and other industries. [0003] Amo...

AI Technical Summary

Problems solved by technology

Usually the crimping of the workpiece is completed by the joint action of the molds divided into even pieces, for example, 8 pieces, 10 pieces, and 12 pieces, and each mold is installed on the mold mounting seat, and there is a gap between the molds when the crimping starts , as the crimping process continues, the gap continues to decrease until the side walls of the molds fit together. In the process of use, the gap distance between the molds is usually different, which makes the outer wall of the pipe fittings stressed unevenly. The roundness error of the buckled pipe fittings is relatively large, which affects the assembly and use of the pipe fittings

On the other hand, if you want to crimp pipes with different executions, you need to replace the mold with the corresponding diameter. The mold replacement in the prior art is particularly difficult and takes a long time to disassemble.
