Abstract

The application provides a joint flange using a thickness-increased and cutting-processed pipe and a method for manufacturing same. The disclosed method for manufacturing a joint flange using a thickness-increased and cutting-processed pipe is characterized by comprising: a pipe cutting step of preparing a pipe and cutting the same into a preset length; a flange forming step of forming a flange, which has a mounting hole for installing a pipe, through diecasting; a bumping / forming step of bumping / forming a thickness-increased portion by increasing the thickness of one end portion of the pipe and forming a first bead that engages with the flange; a cutting / processing step of cutting / processing the circumference of the thickness-increased portion, thereby forming a sealing groove on which anO-ring is installed; and a fixing step of inserting / installing a pipe into the mounting hole of the flange, compressing the other end portion of the pipe such that a second beam is formed, and compressing / fixing the same to the lower end portion of the flange.

Description

technical field [0001] The present application relates to a joining flange using a thickened and processed pipe body and a manufacturing method thereof, and more particularly to a joint flange using a thickened and processed pipe body and a method of processing the pipe by compressing one end, using general-purpose equipment The locking reinforcement ring and the sealing part on the peripheral part of the body, then pressing and fixing the body to the flange made by die casting, increasing the thickness of one end of the body towards the inside and outside, can reduce the joint A manufacturing method that reduces the production time of the flange and reduces its production cost. Background technique [0002] Generally, a cooling system of a vehicle is composed of a compressor, a condenser, an expansion valve, an evaporator and the like, and the components are connected to each other through pipes filled with refrigerant. Under such circumstances, in order to increase the co...
