Description
Technical field
The invention belongs to the cut edge circle shear in steel rolling equipment field or the rack locking device that the adjustment of scrap cutter opening degree finishes, promptly a kind of rotary cutter fluid pressure locking device.
Background technology
The high accuracy cut edge circle shear is one of nucleus equipment that is widely used in metal plate and belt finishing line (units such as rewinding, slitting, straightening, pickling).The precision of opening degree adjustment and stability are one of important indicators wherein.In the process of disk shearing work, the cutting edge of circle shear is subjected to shearing the effect of lateral thrust in the band process, the vibration of equipment itself, and during the unusual sideslip of band to the influence of the factors such as impulsive force of cutting edge, cause that easily opening degree promptly shears the variation of strip width, circle shear is under this condition of severe for a long time works, and the high precision ball leading screw precision that causes opening degree to be adjusted easily is impaired, and the precision that the circle shear opening degree is adjusted reduces with stability.
Before the opening degree adjustment of cut edge circle shear or scrap cutter finished, and unit is prepared to put into operation, the movable base of cut edge circle shear or scrap cutter (the cutter head body is installed on the movable base) must be locked, and unit can coordinated operation.
The employing that existing circle shear opening degree locking function has has the line slideway of hydraulic locking function and realizes, but its bring direct result be with high costs, maintenance cost is big.
For this reason, a kind of easy hydraulic locking mechanism is used in the opening degree of cut edge circle shear or scrap cutter and adjusts, it overcome cost height, the maintenance cost of hydraulic locking line slideway big problem.But owing to still there are problems such as the installation site is unreasonable, when the opening degree adjustment need be opened, there was pressure differential in pipeline, and promptly retaining mechanism still has remaining coupling mechanism force, and plunger case is bigger to the frictional force of movable base, caused the two wearing and tearing to strengthen.
Summary of the invention
The objective of the invention is to be to overcome the weak point of above-mentioned existing equipment, a kind of a kind of rotary cutter fluid pressure locking device that is easy to safeguard simple in structure is provided, with the normal locking that guarantees opening degree with open, eliminate the regular friction between movable base and the plunger case to greatest extent, make that simultaneously device is convenient for installation and maintenance.
The object of the present invention is achieved like this, design a kind of rotary cutter fluid pressure locking device, it is characterized in that: the locking cylinder body 1 of locking device is fixed on the both sides of circle shear firm banking, the tapered end 4 of locking cylinder body 1 is corresponding with movable base lock chamber, fluid pressure line is connected by the oil transportation channel 11 of interface 10 with locking cylinder body 1, and fluid pressure line is communicated with in-line and return line respectively by solenoid directional control valve; When needs were adjusted the circle shear opening degree, solenoid directional control valve made oil transportation channel 11 communicate with the return line of hydraulic system, and spring 2 discharges thrust, forced the tapered end 4 on the piston to be separated with movable base; When the opening degree adjustment finishes, solenoid directional control valve makes oil transportation channel 11 communicate with the in-line of hydraulic system, and piston is subjected to the pressure of hydraulic oil, forces tapered end 4 on the piston 6 outwards to be moved into from locking cylinder body 1 in the lock chamber of movable base and compresses movable base; The oil transportation channel 11 of locking cylinder body 1 is vertical with plunger shaft, and plunger shaft and oil transportation channel 11 constitute L shaped passage, and piston 6 one ends in the plunger shaft are connected with tapered end 4.
Between described piston 6 and the tapered end 4 spring 2 is arranged.
Described piston 6 is socketed with piston packing 5, with oil transportation channel 11 and tapered end 4 seal isolation.
Two bracing rings 3 are installed on the described piston 6.
On the locking cylinder body 1 of the other end that described plunger shaft and tapered end 4 are reverse blind flange 7 is arranged.
Characteristics of the present invention are: because at circle shear firm banking both sides fixing and locking cylinder body 1, the tapered end 4 of locking cylinder body 1 is corresponding with movable base lock chamber, control by one road hydraulic circuit, when needs are adjusted opening degree, reversal valve is opened, fluid pressure line communicates with the return line of hydraulic system, and spring discharges thrust, forces the plunger tapered end to lock into cylinder body and separate with movable base; When the opening degree adjustment finishes, the reversal valve closure, fluid pressure line communicates with the in-line of hydraulic system, and plunger is subjected to the pressure of hydraulic oil, forces plunger tapered end and movable base to compress.During hydraulic control, plunger shaft and oil transportation channel 11 constitute L shaped passage, and piston 6 one ends in the plunger shaft are connected with tapered end 4, have solved and have adopted the line slideway that has the hydraulic locking function to realize the high cost that movable base locking brings, maintenance cost height; Also solved install inconvenient, easy care not, and when fundamentally having solved the pipeline release because plunger case that the pipeline back pressure is brought and the permanent wear problem between the movable base.
