Description
Technical field
The present invention relates to a kind of plain type destressing machine for removing bend pipe stress.
Background technology
Bend pipe is widely used in the various pressure vessels such as boiler, petrochemical industry, Aero-Space, is pipeline system
The important component part of system.Along with the development of modern technologies, the safety applications of pipeline is increasingly by engineering circles
Attention, and as the important component of tubing, the research of bend pipe also receives more and more attention.Curved
Shape and the version of pipe are more complicated, and the bend pipe stress used in engineering is complicated, carries out bend pipe
Mechanical analysis accurately is by bend pipe and manufactures and designs the important prerequisite with Analysis of structural reliability.
Any one workpiece produced all can produce stress, and this source of strength is in workpiece itself, such as ferrum
Part standing time is long can produce flexural deformation, here it is the change that workpiece is produced by stress.By straight steel pipe profit
After bending with bending machine, there is stress in bend pipe, if not carrying out stress relieving, then can cause Tube Bending Deformation.For
Avoid redeformation after tube bending, need the stress that bend pipe is existed to be removed.Existing destressing equipment is tied
Structure is more complicated, complex operation.
Summary of the invention
The technical problem to be solved in the present invention is: existing destressing device structure is more complicated, complex operation.
The technical solution adopted for the present invention to solve the technical problems is: provide one to be used for removing bend pipe stress
Plain type bend pipe destressing machine, concrete structure includes:
Pedestal, is installed vertically on plane on pedestal, and fixes the support being connected with pedestal, be arranged on pedestal

Above-mentioned positioner includes: a pair locating piece, with a pair locating piece with the use of pressing plate and control pressure
The cylinder of a pair locating piece pushed down by plate,
Wherein, a pair locating piece is distributed in the both sides of support, and cylinder is arranged on cradle top, and passes through piston
It is connected with pressing plate,
After the present invention utilizes positioner to be fixed on pedestal by bend pipe, by heater, steel pipe is added
Heat, so that bend pipe stress relieved；
A pair above-mentioned locating piece is respectively and fixedly installed on a pair installing plate, and a pair described installing plate is installed
On pedestal, and be the destressing needs of bend pipe meeting differently curved radius, one of installing plate with
Pedestal is slidably connected, and for the plate that is slidably installed, pedestal is additionally provided with and can control this and be slidably installed plate thereon
The mobile device slided, moves the plate that is slidably installed to the position matched with elbow radius, then that this is sliding
Dynamic installing plate is fixed on pedestal, then is arranged on by locating piece on a pair installing plate respectively and enables to locating piece
With installing plate synchronizing moving so that it is can with pressing plate well with the use of；
As preferably: for the ease of the plate that is slidably installed in the upper adjustment put of pedestal, mobile device is for being arranged on
On pedestal for the regulation plate that is slidably installed at the upper screw mandrel put of pedestal, have and silk bottom the plate that is slidably installed
The screw thread that bar coordinates, screw mandrel one end has handwheel；
For can effectively bend pipe be heated, as preferably: above-mentioned heater includes being arranged on to be determined
Heat block bottom the block of position and the external power source that electrically connects with heat block.
The invention has the beneficial effects as follows: after the present invention utilizes positioner to be fixed on pedestal by bend pipe, pass through
Steel pipe is heated by heater, so that bend pipe stress relieved, equipment is simple, it is simple to operation.
