Description

A kind of steel tube straightening machine
Technical field:
The present invention relates to a kind of steel pipe's production equipment, be specifically related to a kind of steel tube straightening machine.
Background technology:
Steel pipe is widely used in machinery production, pipeline transportation and construction, but steel pipe is in process of production due to the phenomenon that operative is improper or can occur bending and deformation unavoidably under the impact such as unbalance stress, once tube bending distortion, the security performance of use can be affected, cause potential safety hazard, and bended pipe is not easy to recycle, serious economic loss will inevitably be caused.
Summary of the invention:
The present invention, for overcoming the deficiencies in the prior art, provides a kind of steel tube straightening machine, and it can extrude to carry out alignment to it to the steel pipe under the condition of high temperature, improves the qualification rate of steel pipe.
Steel tube straightening machine of the present invention, technical scheme adopted for achieving the above object is: comprise fixed head, movable plate and controller, described fixed head is vertically provided with bracing frame, the upper horizontal of support frame as described above is provided with top board, controller is positioned at the upper surface of top board, the bottom surface of top board is fixed with electric cylinder, the leading screw of electric cylinder down and connect movable plate, the upper surface of described fixed head is provided with the arc lower groove to lower recess, the lower surface of movable plate is provided with the upper deep-slotted chip breaker upwards caved in, upper deep-slotted chip breaker is corresponding up and down with arc lower groove, fixed head is provided with sensor, sensor is by the main control chip on the A/D converter connection control device in controller, main control chip connects electric cylinder by the drive circuit in controller.
As a further improvement on the present invention, be evenly equipped with transfer roller along its length in described arc lower groove, the surface of described transfer roller is in the arc caved inward, and control chip connects the motor driving live-roller to run by drive circuit.Automatically can be transmitted steel pipe by transfer roller, steel pipe is automatically loaded in arc lower groove, or automatically unload in arc lower groove.
As a further improvement on the present invention, described sensor connects A/D converter by the signal conditioner in controller, carries out passing to A/D converter, to improve the accuracy of signal transmission after adjustment is amplified to the signal that sensor detects by signal conditioner.
As a further improvement on the present invention, described sensor is travel switch, and travel switch is located at by arc lower groove, after movable plate touches formation switch, controller can stop the downward operation of electric cylinder leading screw at once, excessively causes overvoltage to make pipe deformation in order to avoid movable plate is descending.
The invention has the beneficial effects as follows: uncooled high-temperature steel tube is placed on fixed head by the present invention, then drive movable plate to run downwards by the leading screw of electric cylinder to extrude the steel pipe on fixed head, thus alignment is carried out to steel pipe.On this basis, the present invention is provided with deep-slotted chip breaker, on fixed head, is provided with arc lower groove on movable plate, is undertaken contacting to avoid the circular surface crimp by steel pipe by upper deep-slotted chip breaker and arc lower groove and the circular surface of steel pipe.Meanwhile, the present invention is provided with transfer roller in arc lower groove, and steel pipe can be sent in deep-slotted chip breaker automatically and carry out extruding alignment, more automatically be shifted out in deep-slotted chip breaker by the steel pipe after alignment, it is simple and efficient to handle, time saving and energy saving.And, the present invention is further advanced by sensor to detect the downstream position of movable plate, prevent movable plate from excessively making steel tube surface generation deformation to steel tube extrusion because of the descending movable plate that excessively causes, sensor can for being located at the other travel switch of arc lower groove, when after movable plate clamping stroke switch, the signal that control chip in controller receives travel switch can stop the operation of electric cylinder leading screw at once, thus prevents movable plate from continuing descending operation, and its handling safety is reliable.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the top view of fixed head;
Fig. 3 is the control principle drawing of controller.
