Split side-open type expansion cold connection equipment for hoses and hose composite parts and operation method of split side-open type expansion cold connection equipment

Abstract

The invention provides split side-open type expansion cold connection equipment for hoses and hose composite parts and an operation method of the split side-open type expansion cold connection equipment. The split side-open type expansion cold connection equipment comprises two parallel arranged oil cylinders with the bottoms fixed to a base, the tops of piston rods of the two oil cylinders are fixed to a front baffle at the same time, and a split tubing fixture is installed in a gap between the two oil cylinders;a fixed centering sleeve is arranged on the lower part of the center of the upperpart of the front baffle, a removable movable centering sleeve is arranged on the upper part of the fixed centering sleeve, and one end of an expanding core mold is clamped in the middles of the fixed centering sleeve and the movable centering sleeve; and a fixed sleeve shrinking mold is arranged on the lower part of the center of the upper part of a rear baffle, and a removable movable sleeve shrinking mold is arranged on the upper part of the fixed sleeve shrinking mold. According to the split side-open type expansion cold connection equipment for the hoses and the hose composite parts andthe operation method of the split side-open type expansion cold connection equipment, all modules can bedisassembled and installed in a splitting mode, the hoses are conveniently and radially separated from the split side-open type expansion cold connection equipment when being used under special working conditions such as integral connection, and meanwhile, maintenance and accessory replacement of the split side-open type expansion cold connection equipment are easy.

Description

technical field [0001] The invention relates to a cold connection device for hoses and hose assemblies, in particular to a hose and hose with simple and reliable structure, ingenious design, convenient disassembly and assembly, no need for frequent replacement of parts, and shrinkage and expansion of cores in sequence. Split side-opening shrinkage-expansion-cooling connection equipment for tube assemblies. Background technique [0002] At present, there are many ways to connect hoses and hose joints in various industries. Among them, the cold connection processing method is widely used because of its reliable connection, fast and convenient connection. Such as pipelines used in petroleum, construction, food and other industries, hydraulic hose assemblies in the hydraulic field, air-conditioning pipelines and flexible shafts in the automotive industry, etc. Hose and hose assembly cold joint processing equipment is the main processing method, and its performance plays a key r...

AI Technical Summary

Problems solved by technology

No matter whether it is shrinking first and then expanding or shrinking first and then shrinking, in the segmented shrinking and expanding operation, it is necessary to replace different combination tools, which is labor-intensive and time-consuming, and the efficiency is low

And it cannot work normally in some special working conditions such as the overall connection of individual shrink sleeves of the pipeline and the flange connection of the pipe end.
