Bent pipe forming die for automobile air conditioner pipeline and using method of bent pipe forming die

Abstract

The invention relates to the technical field of automobile air conditioner pipeline elbow production molds, in particular to an automobile air conditioner pipeline elbow forming mold which comprises a circular mold, the inner wall face of the circular mold is semicircular, a first telescopic cylinder is sleeved with a supporting ring, and the outer wall of the periphery of the supporting ring is connected with a space turning device. The space turning device comprises a plurality of first telescopic cylinders connected with the supporting ring. A core rod is arranged in the middle of the circular mold in a penetrating mode, automatic positioning blocks are movably connected to the outer wall of the core rod in a clamped mode, and the multiple automatic positioning blocks are arranged in the length direction of the core rod at intervals. A continuous pushing guide die is arranged on one side of the circular die and comprises a strip-shaped die body, and the strip-shaped die body is in linkage with the eccentric wheel through a push-pull arm rod. The pipe bending machine can directly bend a pipe in any direction, so that pipe bending machining of an air conditioner pipeline is more efficient, the pipe does not need to be rotated by an angle in the machining process, and the machining efficiency is improved. The slipping risk is avoided, so that the bending direction deviation of the pipe can be prevented.

Description

technical field [0001] The invention relates to the technical field of molds for producing automobile air-conditioning pipes, in particular to a mold for forming pipe bends of automobile air-conditioning pipes and a use method thereof. Background technique [0002] Automobile air conditioner is a device that processes the temperature, humidity, purity, and airflow speed of the air inside the car to meet the needs of people in the car. The machine bends the blank into a certain angle, and the stamping process method of a certain shape workpiece. The bending die is an important basic equipment for the bending process. [0003] Chinese invention patent (CN113198890A) discloses an automobile air-conditioning pipe elbow forming mold capable of processing various bending structures and its use method. This application relates to an automobile air-conditioning pipe elbow forming capable of processing various bending structures The mold includes a wheel mold, a clamping mold for c...

AI Technical Summary

Problems solved by technology

[0005] (1) It bends the aluminum pipe through the cooperation of the wheel mold, the clamping mold and the guide mold. The bending is completed in two steps. The first step is to adjust the bending direction, and the second step is to bend. The two steps are separated. less efficient

[0006] (2) When adjusting the direction of the bending pipe, it is necessary to adjust the angle of the pipe through rotation. During this process, slippage may occur, resulting in a deviation in the bending direction of the pipe
