Description

Hydraulic pressure is cut shearing edge gap adjusting device
Technical field
The utility model belongs to the machining equipment technical field, relates to a kind of hydraulic pressure and cuts shearing edge gap adjusting device.
Background technology
Hydraulic pressure is cut the use that is mainly used in crop, back-end crop on metallurgy industry plate, the band production line.Plate, band account for to such an extent that proportion is very big at steel industry, all there are plate, band production line in each big steel company in the whole nation, need to cut head or afterbody in process of production, perhaps carry out fixed ruler cutting, its frequency of utilization is very high, therefore, through after a while use or according to different product needed the gap of last lower scissor blade is adjusted to meet the needs of production.Existing blade clearance is by the spacer thickness between cutting edge and the tool rest is adjusted, though this control method is simple, waste time and energy and the precision of regulating low, to the thickness requirement on machining accuracy height of pad, manufacture difficulty is big, especially is unfavorable for large-scale use of cutting.
Summary of the invention
The purpose of this utility model provides a kind of hydraulic pressure and cuts shearing edge gap adjusting device, time-consuming, effort that has solved that existing hydraulic pressure cuts that the blade clearance exists in adjusting and the low problem of degree of regulation.
The technical scheme that the utility model adopted is, a kind of hydraulic pressure is cut shearing edge gap adjusting device, comprise hydraulic cylinder, hydraulic cylinder is connected with upper cutter head in being arranged on the support body cavity, between side of upper cutter head and support body inwall, be disposed with one deck cushion layer, a tapered wedges A, a beveled cone, between the opposite side of upper cutter head and support body inwall, be disposed with one deck cushion layer, a tapered wedges B, a beveled cone, tapered wedges A is connected with leading screw A, tapered wedges B is connected with leading screw B, tapered wedges A and tapered wedges B can be respectively slide up and down between the inclined-plane of beveled cone and cushion layer, the lower end of upper cutter head is equipped with cutter, the upper end of the following tool rest corresponding with upper cutter head is equipped with bottom knife, and cutter and bottom knife can be fitted when shearing.
The beneficial effects of the utility model are that it is higher, time saving and energy saving to adjust ratio of precision, has good practicability.
Description of drawings
Fig. 1 is that existing hydraulic pressure is cut the shearing edge gap adjusting device schematic diagram;
Fig. 2 is that hydraulic pressure of the present utility model is cut the shearing edge gap adjusting device schematic diagram.
Among the figure, 1. hydraulic cylinder, 2. upper cutter head, 3. cushion layer, 4. support body, 5. cutter, 6. cutter pad, 7. bottom knife pad, 8. bottom knife 9. descends tool rest, 10. tapered wedges A, 11. leading screw A, 12. beveled cone, 13. tapered wedges B, 14. leading screw B.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As Fig. 1, the structure that existing hydraulic pressure is cut shearing edge gap adjusting device is, hydraulic cylinder 1 is connected with upper cutter head 2 in being arranged on support body 4 cavitys, be provided with one deck cushion layer 3 between upper cutter head 2 and support body 4 inwalls, the lower end of upper cutter head 2 is equipped with cutter 5, is provided with cutter pad 6 in the gap between cutter 5 and the upper cutter head 2; Following tool rest 9 upper ends corresponding with upper cutter head 2 are equipped with bottom knife 8, are provided with bottom knife pad 7 in the gap between bottom knife 8 and the following tool rest 9, and cutter 5 can be fitted when shearing with bottom knife 8.Through after a while use or according to different product needed, situation about exceeding standard has appearred in the gap of last lower scissor blade, will be benchmark this moment with the line of symmetry of cutter 5 and bottom knife 8, utilize the thickness that changes cutter pad 6 and bottom knife pad 7 to adjust, cutter 5 meets the requirements in the shear time crack with bottom knife 8, to satisfy technical needs.This adjusting device is time-consuming when reality is adjusted, effort and degree of regulation are low, especially to the thickness requirement height of pad, makes difficulty.
As Fig. 2, hydraulic pressure of the present utility model is cut shearing edge gap adjusting device, comprise hydraulic cylinder 1, hydraulic cylinder 1 is connected with upper cutter head 2 in being arranged on support body 4 cavitys, between side of upper cutter head 2 and support body 4 inwalls, be disposed with one deck cushion layer 3, a tapered wedges A10, beveled cone 12, between the opposite side of upper cutter head 2 and support body 4 inwalls, be disposed with one deck cushion layer 3, a tapered wedges B13, beveled cone 12, tapered wedges A10 is connected with leading screw B14 with leading screw A11 respectively with tapered wedges B13, tapered wedges A10 and tapered wedges B13 slide up and down between the inclined-plane of beveled cone 12 and cushion layer 3 respectively under the drive of leading screw separately; The lower end of upper cutter head 2 is equipped with cutter 5, and the upper end of the following tool rest 9 corresponding with upper cutter head 2 is equipped with bottom knife 8, and cutter 5 can be fitted when shearing with bottom knife 8.
Hydraulic pressure of the present utility model is cut shearing edge gap adjusting device on the basis that existing hydraulic pressure is cut, on having given up, pad between bottom knife and the respective blade seat, and bottom knife 8 keeps motionless when adjusting, only cutter 5 is adjusted, the adjustment of cutter 5 is to finish by upper cutter head 2 and tapered wedges A10 and cooperating up and down of tapered wedges B13 between the support body 4, the leading screw of adjusting up and down by being connected separately of tapered wedges A10 and tapered wedges B13 carries out, the tapered wedges on both sides is relative motions, when one side tapered wedges A10 is descending, another side tapered wedges B13 is then up, and the descending displacement of tapered wedges A10 equates with the up displacement of another side tapered wedges B13, vice versa, thereby realized the adjustment of upper cutter head 2 horizontal level in support body 4, bottom knife 8 can about move horizontally adjustment accurately, reach closely cooperating when shearing with bottom knife 8.When leading screw is connected with power set, can also realize automatic adjustment, adapt to different hydraulic pressure and cut the blade clearance needs.
The utility model device can be accomplished automatic control, and it is higher to adjust ratio of precision, saves time, and has good practicability.
