Technical field
The present invention relates to cold-strip steel hydraulic shear technical field, be specifically related to a kind of hydraulic shear blade clearance adjusting device.
Background technology
In cold-strip steel technology, when running into the irregular magnetic tape trailer or while there is broken belt situation of taking the lead, need to use hydraulic shear to cut off irregular band steel.Hydraulic shear is by fixing cutting edge and shearing cutting edge and form, during shearing, shear cutting edge by after driving with the tangent realization of fixing cutting edge to the shearing with steel.For the band steel of different-thickness, the gap difference between needed cutting edge, in general, belt steel thickness is thinner, and its corresponding blade clearance is less.In modern cold rolling production, in order to adapt to the demand of market to different size belt steel product, require the product specification that cold-rolling mill is produced to realize variation.When converting product specification in milling train production process, need the corresponding blade clearance of adjusting to adapt to the thickness of this kind of gauge strip steel.In the cold rolling production of tradition, 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 shortcomings such as low precision.
Summary of the invention
The object of this invention is to provide a kind of hydraulic shear blade clearance adjusting device, 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 invention provides a kind of hydraulic shear blade clearance adjusting device, comprise fixing tapered wedges, mobile tapered wedges, drive unit and shearing knife rest lateral thruster;
Drive unit connects to drive this to move tapered wedges with mobile tapered wedges vertically to move; 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 provided by the invention blade clearance adjusting device, by regulating mobile tapered wedges to move up and down, realize moving left and right of knife rest upper scissor blade, and then realize the adjustment of blade clearance, easy to operate, when adjusting blade clearance, adjust precision good, regulate the speed fast, have a good promotion prospects.
Below with reference to accompanying drawing, the present invention is described in further details.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Description of reference numerals: 1, hydraulic shear cutting frame; 2, fixing tapered wedges; 3, mobile tapered wedges; 4, drive unit; 6, shear cutting edge; 7, shear knife rest; 8, fixed block; 9, guide finger; 10, holddown spring; 11, housing pin; 12, compact heap.
The specific embodiment
A kind of hydraulic shear blade clearance adjusting device, comprises fixing tapered wedges 2, mobile tapered wedges 3, drive unit 4 and shears knife rest lateral thruster;
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, in order to control mobile tapered wedges 3, moves up and down.
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 driving mobile tapered wedges 3 to move down with drive unit 4 when, 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 driving mobile tapered wedges 3 to move up with drive unit 4 when, 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.
More than exemplifying is only to illustrate of the present invention, does not form the restriction to protection scope of the present invention, within the every and same or analogous design of the present invention all belongs to protection scope of the present invention.
The parts that the present embodiment does not describe in detail and structure belong to well-known components and common structure or the conventional means of the industry, here not narration one by one.
