Description
Affiliated technical field
The utility model relates to a kind of pressure straightening equipment, especially a kind of semi-automatic alignment equipment that is used for the cold drawing steel tube alignment.
Background technology
The conventional process method that the cold-drawn deep processing is the high-grade steel pipe of production is carried out in hot rolling or welded still pipe, because steel pipe has bending after the cold-drawn, generally needing just can become final finished through pressure straightening.Planer-type straightener automaticity commonly used at present is not high, being mainly reflected in the steel pipe of determining the tube bending summit lifts, rotates and the steel pipe that seaming chuck is aimed on the summit moved respectively and carry out, and because portal frame adopts integral bottom girder, push-down head and lift, move, a side that rotatable parts can not move to lathe bed by portal frame, must steel pipe one end be passed portal frame with crane when making loading and unloading, efficient is low and dangerous.Along with the fast development of Chinese cold drawing steel tube industry, press for the novel pressure alignment equipment that a kind of automaticity is higher, efficient is higher.
Summary of the invention
The purpose of this utility model provides a kind of planer-type pressure straightening machine of brand new, and the realization steel pipe is lifted, rotates, moves semi-automatic, and the steel pipe loading and unloading can be carried out in lathe bed one side, does not need to pass portal frame.
For achieving this end, technical solution adopted in the utility model is as follows:
This semi-automatic cold drawing steel tube straightener is made up of lathe bed, gantry pressure frame, lifting reversing frame, push-down head and supporting hydraulic system, control system.Interior guide rail, outer guide two secondary guide rails are arranged on the lathe bed, and two secondary guide rails are parallel to each other; There is twice hook plate groove the lathe bed both sides, and the direction of hook plate groove is parallel with guide rail; Inboard tooth bar is fixed on interior rail-sides, two outboard rack are fixed on lathe bed two lateral surfaces, and each tooth bar direction is parallel with guide rail; Gantry pressure frame has the bottom girder of two separation, two bottom girders place respectively on the outer guide of lathe bed both sides, move along outer guide, distance between two bottom girders can be by lifting reversing frame and push-down head, hook plate on the bottom girder is inserted in the hook plate groove of lathe bed both sides, the hook plate groove is born the counter-force in when pressurization, and gantry pressure frame drive motors is installed on each bottom girder, gantry pressure frame driven wheel on the motor shaft respectively with two outboard rack engagements in the lathe bed outside; In placing, two lifting reversing frames on the guide rail,, a lifting reversing frame drive motors is installed on each lifting reversing frame, lifting reversing frame driven wheel on the motor shaft and the engagement of inboard tooth bar along interior guide rail movement; Two push-down heads place on the interior guide rail, and between two lifting reversing frames, along interior guide rail movement, a push-down head drive motors are installed on each push-down head, push-down head driven wheel on the motor shaft and the engagement of inboard tooth bar.
Be fixed with a vertical column respectively on two bottom girders of gantry pressure frame, back timber is being fixed in two root posts upper end, is fixing oil pressure cylinder on the back timber, is fixing seaming chuck anvil piece on the oil pressure cylinder piston rod.
The matrix of lifting reversing frame is a lifting reversing frame base, lifting reversing frame drive motors is installed on the lifting reversing frame base, two elevating rams are installed in lifting reversing frame base both sides, two sides of Trolley case are separately fixed on the piston rod of two elevating rams, the roller drive motors is installed on the Trolley case outer wall, this motor shaft stretches in the Trolley case, fixing driving gear on the axle, on the Trolley case rotating be installed with two with the parallel roller shaft of roller drive motors axle, fixing a driven gear and a roller on the every roller shaft, two driven gears mesh with driving gear respectively.
The matrix of push-down head is the push-down head base, and the push-down head drive motors is installed on the push-down head base, and push-down head anvil piece is fixed on the push-down head base.
During this semi-automatic cold drawing steel tube straightener work, start two gantry pressure frame drive motors, by two gantry pressure frame driven wheels respectively with the engagement of two outboard rack of lathe bed both sides, make gantry pressure frame move to lathe bed one end along outer guide.Start push-down head and the push-down head drive motors on the lifting reversing frame and the lifting reversing frame drive motors of this end, engagement by push-down head driven wheel and lifting reversing frame driven wheel and inboard tooth bar, the push-down head and the lifting reversing frame of this end are moved along interior guide rail, by the neutral between two bottom girders of gantry pressure frame, move to the opposite side of gantry pressure frame.This moment, two push-down heads and two lifting reversing frames all were positioned at a side of gantry pressure frame, and steel pipe can directly be put on the roller of lifting reversing frame, need not pass gantry pressure frame.At first start four elevating rams on two lifting reversing frames during the steel pipe material loading, its piston rod is stretched out, the Trolley case that is fixed on the piston rod increases, and the steel pipe two ends are put into respectively on two lifting reversing frames, and the every end of steel pipe all is that frame is between two rollers.Because this moment, roller was in a high position, the steel pipe on it is higher than the push-down head anvil piece on the push-down head, and steel pipe does not contact with the inclined-plane of push-down head anvil piece.Start the roller drive motors on two lifting reversing frames, driving gear rotation on the motor shaft, and drive the driven gear rotation that is engaged with on the roller shaft, the roller that is fixed on the roller shaft rotates thereupon, and steel pipe is rotated by frictional force, can find the summit of tube bending.Two push-down heads move to the both sides on tube bending summit respectively subsequently, and elevating ram counteragent, piston rod drive Trolley case and descend, and steel pipe is fallen on the push-down head anvil piece, and roller and steel pipe disengage.Start gantry pressure frame drive motors, gantry pressure frame is moved, the seaming chuck anvil piece on it arrives the top on tube bending summit.Starting pressure oil cylinder, oil pressure cylinder piston rod drive seaming chuck anvil piece and are depressed on the steel pipe, with the steel pipe alignment.The counter-force that depress this moment is applied on the lathe bed hook plate groove by the bottom girder hook plate, is born by the hook plate groove.Because may there be several crooked summits in steel pipe, can also lift steel pipe with two lifting reversing frames during operation and move, cooperate moving of gantry pressure frame and two push-down heads, adjust the position of exerting pressure quickly and finish whole alignment work.Oil pressure cylinder reverse operation after alignment is finished, the oil pressure cylinder piston rod drives seaming chuck anvil piece and rises, gantry pressure frame moves to lathe bed one end again, the elevating ram action is lifted steel pipe from the pop-up of push-down head anvil piece, just can blanking, needn't from gantry pressure frame under pass equally because steel pipe is positioned at gantry pressure frame one side this moment.
The beneficial effects of the utility model are: by invented with steel pipe lift, rotate, move three functions be integrated in one on the lifting reversing frame new construction and the new construction of separate type gantry pressure frame bottom girder, the realization steel pipe is lifted, rotates, moves semi-automatic, and the steel pipe loading and unloading can be carried out in lathe bed one side, do not need to pass portal frame.For the cold drawing steel tube alignment provides advanced equipment.
