Automatic pipe bender for stainless steel pipes and bending method thereof

Abstract

The invention relates to an automatic pipe bender for stainless steel pipes and a bending method thereof. The automatic pipe bender comprises a base, a bending frame, a bending head assembly, a bending seat and a bending driving device, wherein the bending frame is installed on the base, the bending head assembly is fixed to the upper end of the bending frame, the bending seat can vertically slide on the bending frame, the bending driving device is used for driving the bending seat, the bending head assembly comprises a bending head fixed seat which is fixed to the upper end of the bending frame and a bending head which is fixed to the lower part of the bending head fixed seat, and a steel pipe bending groove is formed in the lower end of the bending head; the bending seat comprises a V-shaped bending fixed seat which is installed on the bending frame in a sliding mode through vertical guide wheels on both sides, and a plurality of bending abutting rods are arranged on the V-shaped bending fixed seat; and a steel pipe feeding device, an elbow taking device and an elbow output device are further installed on the base. The automatic pipe bender has the advantages of high bending accuracy, high bending stability, high bending efficiency and low labor intensity.

Description

technical field [0001] The invention relates to the field of automatic mechanical equipment, in particular to automatic bending equipment for steel pipes. Background technique [0002] Steel pipe bending equipment is used to bend steel pipes. For example, the application number is "201620754733.9" and the name is "a high-efficiency steel pipe bending machine". It uses a vertical piston cylinder to directly drive the bending pipe seat to bend the pipe. The biggest disadvantage is that the stroke of the piston cylinder 1. The driving force cannot be adjusted accurately, and the steel pipe can only be roughly bent, not finely bent; moreover, the steel pipe after bending can only be taken out manually because the shape changes from straight to U-like curved; manual operation , the first is low efficiency, which reduces the bending efficiency of the entire pipe bender, and the second is a safety risk. Contents of the invention [0003] In view of the problems still existing i...
