Bending machine

Abstract

The invention discloses a bending technology for plastic profile. The technology comprises the following steps: step a, moulding a plastic pipe or choosing a moulded plastic pipe; step b, heating the part to be bended of the plastic pipe so as to soften the part or heating the whole plastic pipe so as to soften the whole plastic pipe; step c, placing the part to be bended of the plastic pipe in a section mould or a wheel mould, and finally bending and moulding the plastic pipe. Through the provided method, the bending can be carried out in a predetermined route, and thus the bending precision is improved.

Description

technical field [0001] The invention relates to the field of processing equipment, in particular to a plastic pipe bending machine. Background technique [0002] The huge plastic market has played a role in promoting the development of the plastic machinery industry. The plastic machinery industry has a wide range of applications, including packaging, agriculture, construction, automobiles and other fields. With the continuous development of the domestic petrochemical industry, my country's plastic machinery industry has gradually formed an independent industrial sector and has begun to take shape. The development of my country's plastic machinery industry is very fast, basically achieved leapfrog development, and the scale of the industry is also constantly expanding. [0003] Existing plastic pipe bends are mainly trimmed and formed by flat welding, and a circular pipe is flat-welded on a circular pipe mouth. The manufacture is cumbersome, the curvature is small, and the...
