Utility model content
The purpose of this utility model is to provide a kind of hydraulic shear blade clearance governor motion, overcome in traditional cold rolling production, adjust hydraulic shear blade clearance generally by adjusting pad, using the modes such as jackscrew to carry out, these method ubiquities are regulated the speed slowly, adjust the problem of the shortcomings such as low precision.
For this reason, the utility model provides a kind of hydraulic shear blade clearance governor motion, comprises fixing tapered wedges, mobile tapered wedges, drive unit and shearing knife rest lateral thruster;
Drive unit connects with mobile tapered wedges; This moves tapered wedges and is placed in fixing tapered wedges and shears between knife rest lateral thruster; The inclined-plane of mobile tapered wedges is relative with the inclined-plane of fixing tapered wedges and be set parallel to each other.
Described shearing knife rest lateral thruster is by fixed block, guide finger, holddown spring, housing pin and compact heap composition;
Described compact heap is placed between described fixed block and mobile tapered wedges;
On described fixed block, offer the tapped through hole perpendicular to described compact heap, holddown spring is placed in this tapped through hole, the outer end thread connection of described housing pin and this tapped through hole; Conflict in the inner of described housing pin in the outer end of holddown spring, the inner of this holddown spring presses on described compact heap;
Described guide finger passes described fixed block and inserts in the pin-and-hole on described compact heap along the direction perpendicular to described compact heap.
Described guide finger and holddown spring all have two at least, symmetrical in the horizontal direction on fixed block respectively, and corresponding holddown spring and housing pin are at least all two.
Described drive unit is oil cylinder, screw jack gas-distributing motor or hydraulic motor.
This hydraulic shear blade clearance governor motion that the utility model provides, realize moving left and right of knife rest upper scissor blade by regulating mobile tapered wedges to move up and down, and then realize the adjustment of blade clearance, easy to operate, in the time adjusting blade clearance, adjust precision good, regulate the speed fast, have a good promotion prospects.
Below with reference to accompanying drawing, the utility model is described in further details.

Detailed description of the invention
A kind of hydraulic shear blade clearance governor motion, comprises fixing tapered wedges 2, mobile tapered wedges 3, drive unit 4 and shears knife rest lateral thruster;
Drive unit 4 connects to drive this to move tapered wedges 3 with mobile tapered wedges 3 vertically to move; This moves tapered wedges 3 and is placed in fixing tapered wedges 2 and shears between knife rest lateral thruster; The inclined-plane of the inclined-plane of mobile tapered wedges 3 and fixing tapered wedges 2 is relative and be set parallel to each other.
Described shearing knife rest lateral thruster is by fixed block 8, guide finger 9, and holddown spring 10, housing pin 11 and compact heap 12 form;
Described compact heap 12 is placed between described fixed block 8 and mobile tapered wedges 3;
On described fixed block 8, offer the tapped through hole perpendicular to described compact heap 12, holddown spring 10 is placed in this tapped through hole, the outer end thread connection of described housing pin 11 and this tapped through hole; Conflict in the inner of described housing pin 11 in the outer end of holddown spring 10, the inner of this holddown spring 10 presses on described compact heap 12;
Described guide finger 9 passes described fixed block 8 and inserts in the pin-and-hole on described compact heap 12 along the direction perpendicular to described compact heap 12.
Described guide finger 9 and holddown spring 10 all have two at least, symmetrical in the horizontal direction on fixed block 8 respectively, and corresponding holddown spring 10 and housing pin 11 are at least all two.
Described drive unit 4 is oil cylinder, screw jack gas-distributing motor or hydraulic motor, and their clutch end is connected on mobile tapered wedges 3, moves up and down in order to control mobile tapered wedges 3.
Described hydraulic shear blade clearance adjusting device is applied on hydraulic shear, as shown in Figure 1, generally, on hydraulic shear cutting frame 1, have twice cross slide way abreast, shear knife rest 7 and be arranged on the guide rail on hydraulic shear cutting frame 1, can make like this to shear knife rest 7 can horizontally slip; Shear cutting edge 6 and be arranged on shearing knife rest 7 front ends, described fixing tapered wedges 2 and fixed block 8 are parallel fixing on hydraulic shear cutting frame 1, stick and shear knife rest 7 between mobile tapered wedges 3 and compact heap 12.
With reference to Fig. 1, extruding holddown spring 10 after housing pin 11 is tightened on fixed block 8, makes holddown spring 10 have certain pretightning force and acts on compact heap 12.
When drive mobile tapered wedges 3 to move down with drive unit 4 time, under pretightning force effect, to shear knife rest 7 and compact heap 12 and be moved to the left, the shearing cutting edge 6 of now shearing on knife rest 7 is also moved to the left, and realizes the increase of blade clearance; In like manner, when drive mobile tapered wedges 3 to move up with drive unit 4 time, under pretightning force effect, shear knife rest 7 and compact heap 12 and move right, the shearing cutting edge 6 of now shearing on knife rest 7 also moves right, and realizes reducing of blade clearance.The distance that the adjustment amount of blade clearance can move by mobile tapered wedges 3 and the slope of tapered wedges calculate and get, and realize accurate adjustment.
