Description

Bending machine

Technical field

It the utility model is related to a kind of pipe fitting processing equipment field, more particularly to a kind of bending machine.

Background technology

Bending machine is roughly divided into CNC tube bending machine, hydraulic pipe bender etc., applied to power construction, public railway construction, bridge, Ship etc. pipe laying and build, have that function is more, rational in infrastructure, simple operation and other advantages.

The existing Chinese patent for referring to Publication No. CN202070621U, it discloses a kind of air pressure pipe bender, bag Workbench, cylinder assembly, bend pipe indent and slot rolling are included, the cylinder piston of cylinder is curved by telescopic shaft pole bridge piece indent Pipe indent is provided with the semicircular notch to match with pipe diameter, is provided with workbench and positions and coordinate curved for observing both ends Pipe indent carries out two slot rollings of bend pipe, and slot rolling is provided with the semicircular notch that matches with pipe diameter, before cylinder piston Entering and retreating promotes telescopic shaft pole and bend pipe indent to advance or retract to through hole platform direction.

In use, pipe fitting is placed at bend pipe indent, cylinder elongation drives bend pipe indent to advance to workbench direction, most Whole pipe fitting stress between bend pipe indent, slot rolling is bent to the angle of setting.Cylinder, which shortens, drives bend pipe indent to move back to initial bit Put, take out the pipe fitting bent, pipe fitting process finishing.

During due to pipe fitting is placed at bend pipe indent, the bottom of pipe fitting does not have directly with base contacts, it is necessary to worker With hand steered firmly pipe fitting.When cylinder promotes bend pipe indent, pipe fitting is close to slot rolling together therewith, during throw away and need worker to help to manage Part, auxiliary pipe fitting move together therewith, when pipe fitting abuts with slot rolling, just bending machine starts real bend pipe work, in order to protect Bend pipe precision is demonstrate,proved, to treat bending place at pipe fitting alignment bend pipe indent when worker need to ensure to place pipe fitting, if the position of pipe fitting is put partially, The pipe fitting bending place after bending can be caused not to be intended to bending place, waste product is caused, cause substantial amounts of waste.

Utility model content

The purpose of this utility model is to provide a kind of bending machine for being easy to pipe fitting to position.

Above-mentioned technical purpose of the present utility model technical scheme is that：
