Description
Technical field
This utility model belongs to medium frequency bending of pipe and manufactures instrument, is the clamping stopping means for bending medium frequency bending of pipe.
Background technology
With developing rapidly of China's power industry, capacity of power unit is increasing, and unit is also from subcritical rapid
Open up super-critical and ultra super-critical power unit, nearly 2 years supercritical and extra-supercritical unit have reached 70% using bend pipe design, and intermediate frequency is curved
Pipe has been most common and most important pipe fitting in main steam, reheat heat steam and cold reheaing steam pipe.
The process of medium frequency bending of pipe is to treat induction coil on bight portion set in steel pipe, blocks tube head with mechanical rocker arm, in induction coil
In be passed through electric current of intermediate frequency heating steel pipe, when temperature of steel pipe is increased to mecystasises, in steel pipe rear end mechanical thrust along circular arc
Track propulsion bent, the steel tubing portions bending out rapidly with coolant cool down, such while heating, while advance, side bends,
Side cools down, and constantly bends out by bend pipe.
Bend pipe structure size has two big key elements：One is bending radius, and two is bend pipe angle.If this two parameters have larger
Error, it will cause huge trouble to in-site installation, have even cannot install.Therefore, the bending radius of medium frequency bending of pipe, especially
It is that being precisely controlled of angle has just become the key link needing in medium frequency bending of pipe manufacturing process strictly to control.
The medium-frequency pipe bender that domestic pharmaceutical industry Ye Ge manufacturer is used at present is all the homemade non-standard equipment of this enterprise, general
In the serious problem of bend pipe angle and bending radius error, the main cause producing this problem is mechanical rocker arm dop folder to store-through
Not, bend pipe sliding in dop clamp force occurs.Its processing method is typically with being reinstalled medium-frequency pipe bender original
On the basis of continue to be bent again or design specialized mould carries out secondary back pressure.Can be existed as follows using above two method
Problem：First, because straight tube has been bent into the circular of wide-angle, itself has unsymmetry, and precisely lifting is highly difficult,
And the segmental arc that rises at the place of continuing for the medium frequency bending of pipe occurs fold, creates certain impact to the presentation quality of bend pipe；Second, adopt
Need to design moulds of industrial equipment with secondary back pressure, undoubtedly considerably increase the production cost of product.Therefore, up to the present, how
A kind of solution substituting this technique can be developed, reach Reducing Cost in Enterprises, improving market competition advantage has become each
The focus of enterprises pay attention.
