Pipe bending and cutting all-in-one machine for metal pipe machining

Abstract

The invention relates to the technical field of pipe bending machines, and especially relates to a pipe bending and cutting all-in-one machine for metal pipe machining. The pipe bending and cutting all-in-one machine for metal pipe machining comprises a machine body; a mandrel is arranged on the machine body; the mandrel is sleeved by a pipe; a pipe bending mechanism for bending the end part of the pipe is arranged at the end part of the machine body; the end part of the mandrel is coaxially connected with a connecting rod; the end part of the connecting rod is fixedly connected with the machine body; the diameter of the connecting rod is smaller than that of the mandrel; the connecting rod is sleeved with a limiting plate; the end of the pipe abuts against the limiting plate; the limitingplate is fixedly connected with one end of a first hydraulic cylinder; the first hydraulic cylinder is parallel to the connecting rod; the other end of the first hydraulic cylinder is fixed to the machine body; and a cutting mechanism for cutting the pipe at the joint of the mandrel and the connecting rod is arranged in the middle of the machine body. Cutting and bending one-time forming of the pipe can be achieved, so that the process and equipment are saved, and the purpose of reducing the cost is achieved.

Description

technical field [0001] The invention relates to the field of pipe bending machines, in particular to a pipe bending and cutting integrated machine for processing metal pipes. Background technique [0002] Pipe bending machine refers to the machine used for pipe bending and can also be used as a jack. It is roughly divided into numerical control pipe bending machine and hydraulic pipe bending machine. The general structure of the pipe bending machine in the prior art is to include a mandrel. When the pipe is bent, the pipe is sleeved on the mandrel, and the mold provided on the pipe bender bends the end of the pipe. This kind of pipe bending The machine is relatively easy to implement, but correspondingly, the pipe needs to be cut into a specified length before the pipe is bent, which requires manual cutting, or an additional CNC cutting machine is purchased to cut the pipe, no matter which one is used Either way will result in an increase in cost.

Problems solved by technology

[0003] The purpose of the present invention is to solve the shortcomings in the prior art that the cutting of the pipe material and the one-time forming of the pipe bending can not be realized, and a kind of bending pipe cutting integrated machine for metal pipe processing is proposed.
