A kind of pipe bending die and bending pipe pressing method

Abstract

The invention provides a pipe bending die. The pipe bending die includes an upper die and a lower die, wherein the upper die comprises an upper template, an elastic limiting push rod, an upper die oscillating rod and an upper die bending block, and the lower die comprises a lower template, a lower die seat, a pipe bending wheel and a lower die oscillating arm. The invention further provides a bent pipe pressing method. Through the pipe bending die and the bent pipe pressing method, a bent pipe with small deformation can be efficiently obtained by bending; a pipe of which the bending angles at the two ends have the requirements of obverse bending and then reverse bending can be compressed by two working procedures by means of cooperation of up-and-down swing of the lower die oscillating arm with the upper die bending block.

Description

technical field

[0001] The invention relates to a mold, in particular to a pipe bending mold for bending pipes and a pipe bending pressing method. Background technique

[0002] The metal pipe is hollow. According to the needs of use, the pipe is usually bent. Due to the hollow characteristics of the pipe, the existing pipe bending device deforms too much when bending the pipe and causes the pipe to become unstable. If the deformation of the pipe is not enough, the It will lead to rebound at the bend, and the ideal bending effect cannot be achieved.

[0003] At the same time, when the bending process of the pipe is relatively complicated and the bending angle is required to be high, for example, the bending angle of the two ends of the pipe requires both front bending and then reverse bending at both ends. The existing pipe bending device needs to go through four It takes a long time to bend repeatedly to meet the angle requirements of the parts. Contents of the invention ...
