Description
Technical field
The present invention relates to a kind of hydraulic pressure automatic guide mechanism, specifically a kind of hydraulic pressure auto-guider before big rod hydraulic shear, belong to the technical field of large-scale special steel steel rolling equipment.
Background technology
Big rod is after completing breaking down through blooming mill, for avoiding the most irregular blank affect the quality of product after being directly entered tandem rolling or damage guide and guard between frame, generally need to be carried out crop by hydraulic shear, back-end crop processes, but the guider before existing hydraulic shear is for manually adjusting structure, cannot along with the shearing motion of hydraulic shear dexterous actions, in turn result in the blank after shearing end to end because of with fixed guide interfere and cause bending, and then be difficult to enter tandem mill carry out postorder rolling.Because the bending of blank, especially at head, nipping of tandem mill will be had a strong impact on, the most not only affect the rhythm of production of rolling line, improve production cost, but also the auxiliary devices such as the roller table apron of milling train, roller-way protective cover, guide and guard may be damaged.The further raising required along with big stick-means of intimidation finished product, the production requirement of rolling line also will higher by high-grade product, guider problem how to solve also will become the bottleneck that limit product produces, therefore solution the problems referred to above also become more urgent.In view of technical problem present in prior art, therefore, guider before a kind of hydraulic shear that can automatically adjust of exigence.
Summary of the invention
The present invention is just for technical problem present in prior art, it is provided that hydraulic pressure auto-guider before a kind of big rod hydraulic shear, this device overall construction design is ingenious, significantly improves the productivity ratio of tandem mill, reduces energy consumption and cost.
nullTo achieve these goals，The technical solution used in the present invention is，Hydraulic pressure auto-guider before a kind of big rod hydraulic shear，Including rotating guide wheel mechanism，Leading arm，Hydraulic cylinder，Hydraulic cylinder base，Described rotation guide wheel mechanism is assembled together with leading arm，All it is connected by described movable connection structure between described leading arm with hydraulic cylinder and hydraulic cylinder with hydraulic cylinder base，Described rotation guide wheel mechanism includes guide wheel，Self-aligning roller bearing，Guide wheel shaft，Locking nut and end cap，Described self-aligning roller bearing is between guide wheel and guide wheel shaft，Described end cap is socketed in one end of guide wheel shaft，Connect on the other end of described guide wheel shaft and have locking nut，Described leading arm is between guide wheel and locking nut，Described movable connection structure includes oscillating bearing，Connecting shaft，Clamping screw and limited block，Described oscillating bearing is fixed on the middle part of connecting shaft，Described limited block is positioned at the lower section of clamping screw cap.The ingenious practicality of whole Technical Design, can make rolled piece smoothly enter hydraulic shear, and rolled piece can be enable again can to automatically move in the same direction along with cutting edge action when hydraulic shear cutting edge is sheared.Thus the bending avoiding rolled piece to cause because interfering with fixed guide, make rolled piece can enter tandem mill smoothly and carry out the production of subsequent processing.
As a modification of the present invention, the quantity of described self-aligning roller bearing is 2, is separately mounted to the two ends of described guide wheel.Thus ensure that guide wheel stress equalizes, extend its service life.
As a modification of the present invention, described guide wheel can be freely rotatable.Owing to the front end of middle square billet with guider exists sliding friction, easily scratch blank, the guide wheel that can rotate freely is used in this device, friction between the two is become rolling friction from original sliding friction, so not only reduce the cut that blank causes due to friction, also substantially increase the service life of guider simultaneously.
As a modification of the present invention, the stroke of described hydraulic cylinder is controlled by being arranged on the travel switch driving hydraulic cylinder side.According to the size of middle square billet, only need to manually adjust the travel switch position controlling hydraulic cylinder travel before manufacture, in work process, the signal detected is fed back to the electromagnetic valve on hydraulic valve platform every time and then automatically controls the stroke of hydraulic cylinder by travel switch.
As a modification of the present invention, the quantity of described movable connection structure is 2.2 movable connection structures are respectively used to connect leading arm and hydraulic cylinder and hydraulic cylinder and hydraulic cylinder base.So can effectively simplify the design of this device and the complexity manufactured, reduce production cost.
As a modification of the present invention, the two ends of described hydraulic cylinder are respectively arranged with a through hole.Also through hole is offered, it is simple to be directed to the connection between arm and hydraulic cylinder and hydraulic cylinder and hydraulic cylinder base in the relevant position of leading arm and hydraulic cylinder base.
As a modification of the present invention, described limited block offers a through hole, and the size of through hole is suitable with the size of clamping screw.Described clamping screw makes whole movable connection structure fix with corresponding construction through the through hole of limited block to be connected.
As a modification of the present invention, on the basis of described hydraulic cylinder base is fixed on by chemical anchor bolts.Chemical anchor bolts have stronger anchor force, it is possible to ensure that hydraulic cylinder base will not produce loosening phenomenon in the course of the work.
As a modification of the present invention, the center of rotation of described leading arm is fixed on the side of roller-way.Thus ensure that the hydraulic shear with blank cutting head cutting tail can be with synchronization action, it is to avoid when blank cutting head cutting tail, cause blank to bend because itself and hydraulic shear are asynchronous；Use as guider when i.e. working, use as channel blind after blank enters hydraulic shear.
Relative to prior art, advantages of the present invention is as follows, 1) overall construction design is ingenious, and it is relatively low that dismounting assembles convenient maintenance and replacement, cost；2) this device can make rolled piece smoothly enter hydraulic shear, rolled piece can be enable again to automatically move in the same direction along with cutting edge action when hydraulic shear cutting edge is sheared, make rolled piece can enter tandem mill smoothly and carry out the production of subsequent processing；3) this device can be according to the size of middle square billet, only need to manually adjust the travel switch position controlling hydraulic cylinder travel before manufacture, in work process, the signal detected is fed back to the electromagnetic valve on hydraulic valve platform every time and then automatically controls the stroke of hydraulic cylinder by travel switch, thus ensure that hydraulic cylinder the most all can carry out action as requested, it is finally completed automatic guide；4) bigger with the friction of guider front end due to middle square billet, it is easily caused blank to scratch, the guide wheel that can rotate freely is employed in this device, friction between the two is changed into rolling friction by original sliding friction, not only reduce the cut that blank causes due to friction, and substantially increase the service life of guider；5) this device can adapt to the guiding requirement of middle square billet of all size size, it is possible to ensures that tandem mill is nipped blank the most smoothly, significantly improves the productivity ratio of tandem mill, accelerate rolling rhythm, reduce production cost and energy resource consumption.
