Pipe bender

Abstract

The invention discloses a pipe bender, which relates to a non-cutting processing device, and aims to provide a pipe bender which is low in equipment investment, good in pipe bending quality and high in production efficiency. The pipe bender comprises a frame and a bending template, wherein the middle of the frame is provided with a bedplate which is opposite to an upper template at a piston rod of a cylinder above the bedplate, and holes at the left and right sides of the upper template are respectively rotatablely fitted with end axles of left and right second roll rods; base plates of the frame at the left and right sides of the bedplate are respectively provided with a vertical cylinder, and shafts at the front and rear ends of a first roll rod are respectively and rotatablely fitted with holes at the middle parts of front and rear rocking plates; and a connecting rod at the lower end of the rocking plate is hinged with a piston rod of the vertical cylinder, and holes at the upper ends of the front and rear rocking plates are rotatablely fitted with two end axles of the second roll rod.

Description

Technical field: [0001] The invention relates to a non-cutting processing equipment, in particular to a pipe bending machine. Background technique: [0002] Now there is a kind of refrigeration product whose shape of the refrigeration pipe is relatively complicated. Its structure is that the refrigeration pipe is a plurality of parallel U-shaped pipes, and this kind of pipe forms an Ω groove at the foot of each U-shaped pipe end. When installing the equipment, the cost of the equipment is high, but with ordinary pipe bending equipment, the pipe bending efficiency is low and the quality is unstable. Invention content: [0003] The object of the present invention is to provide a pipe bending machine with less investment in equipment, good pipe bending quality and high production efficiency. The main point of the technical solution of the present invention is that a pipe bending machine includes a frame and a bending formwork, which is characterized in that: a pl...
