Bending mechanism for producing spiral exposed tubes

Abstract

The invention provides a pin bending mechanism for producing a spiral exposed pipe. The pin bending mechanism comprises a frame, a Z-direction motor, a Z-direction ball screw, an up-and-down adjusting plate, a guide sleeve, a guide pillar, a first pin bending device and a second pin bending device, wherein the Z-direction motor is arranged on the frame, the Z-direction ball screw is vertically arranged, one end of the Z-direction ball screw is connected with an output shaft of the Z-direction motor, the up-and-down adjusting plate is horizontally arranged, the central area of the up-and-down adjusting plate is fixedly connected with a Z-direction screw nut of the Z-direction ball screw, the guide sleeve is fixed on the frame, one end of the guide pillar is fixed on the up-and-down adjusting plate, the other end of the guide pillar penetrates the guide sleeve so as to guide the movement of the up-and-down adjusting plate along a Z direction, the first pin bending device is used for bending a first pin of the spiral exposed pipe, the second pin bending device is used for bending a second pin of the spiral exposed pipe, structures of the first pin bending device and the second pin bending device are identical, and the first pin bending device and the second pin bending device are symmetric to each other relative to a rotation shaft of the Z-direction ball screw. According to the invention, the produced spiral exposed pipe has the advantages of a high qualified rate, good angle consistency between the pin and a pipe body, an accurate size and high efficiency.

Description

technical field [0001] The invention relates to a spiral exposed pipe manufacturing equipment, in particular to a bending foot mechanism for producing spiral exposed pipes. Background technique [0002] At present, most of the bending process of the spiral exposed tube is manual operation. The operator holds the lamp tube to heat the bent foot on the flame, and then bends it into the desired shape by hand. The production practice shows that the artificially produced open pipes have uneven appearance, poor angle and shape consistency, and high labor costs. In view of this, the industry has developed some production auxiliary equipment, but due to the unreasonable design of the mechanical structure, heating head, fixture bending mechanism, etc., and poor consistency of semi-finished products, the pass rate of the product is low, and the production efficiency is very low. Contents of the invention [0003] The object of the present invention is to provide a bending mechanism...
