Numerical control push type pipe bending machine and bending method thereof

Abstract

The invention discloses a numerical control push type pipe bending machine and a bending method thereof. The pipe bending machine comprises a power vehicle which can move freely and an operation table disposed at the top of the power vehicle. The power vehicle comprises a carriage and wheels which are disposed at four corners of the bottom of the carriage. A hydraulic power station is disposed inside the carriage. Two ends of the hydraulic power station are fixed inside two ends of the carriage. A carriage door is disposed on one side of the carriage. The outer wall, close to the carriage door, of the lower portion at one end of the carriage is respectively provided with a wire inlet connector and a computer socket. A power switch is disposed above the wire inlet connector and the computer socket. An oil cylinder is disposed in the operation table. A bending die is disposed on the table board of the operation table. The operation table is further provided with a slide plate for connecting the oil cylinder and the bending die. A plurality pairs of pin holes for disposing a fixing rack are formed in the table board of the operation table. The numerical control push type pipe bending machine is simple in structure, high in pipe bending strength, high in section forming quality, small in size and machining space, and capable of batch machining.

Description

technical field [0001] The invention relates to a pipe bender, in particular to a numerically controlled hydraulic top-bending pipe bender and a bending method thereof. Background technique [0002] Bending pipe processing is widely used in the existing society. It is mainly divided into two fields: industrial products and daily necessities. Industrial products include engineering machinery, metallurgy, building materials, boilers, military industry, amusement and all metal pipes used in hydraulic systems. . Daily necessities including tables and chairs, handrails, fences, doors and windows are also widely used. [0003] There are two types of pipe bending processing: hot bending processing and cold bending processing: hot bending processing is to heat the pipe fittings to reduce the bending resistance and form them while hot bending is mainly used in places without pipe bending equipment and on special materials. Cold bending means direct pipe bending without heating. ...

AI Technical Summary

Problems solved by technology

However, its fixtures and accessories are complicated, the equipment is bulky, the cost is high, and the bending force is small, and it is troublesome to replace the mold. In addition, the bending mold of this form of pipe bending machine cannot use reverse deformation to control the quality of the bent pipe section, otherwise the pipe will fall into the bending mold. Not easy to release the mold

[0006] 2. Top bending machine, only manual on the market

Although the volume is small, the machine head cannot rotate freely, and the pipe will sweep with the change of bending when bending, and the processing space occupied by long pipe processing is large

In addition, the roundness quality of the bent section is poor, and the forming angle is controlled manually, which is not suitable for mass production
