Abstract
The utility model discloses scissors for a plate shearing machine. The scissors comprise an upper blade and a lower blade. The edges of the upper and the lower blades are V-shaped. The edges of the upper blade and the lower blade have the same inclination. By using the above-mentioned method, the scissors can effectively reduce deformation of sheet materials after cut and burrs.
Description
Technical field
The utility model relates to shearing machine apparatus field, particularly relates to a kind of scissors for plate shearing machine.
Background technology
Plate shearing machine is equipment conventional in machining, and plate shearing machine utilization adopts rational gap blade, utilizes the cutting blade of motion and fixing ledger-plate, and the sheet material of various thickness is applied to shearing force, makes the sheet material separation of rupturing as requested.Plate shearing machine of the prior art is generally upper move and lower cut formula, be that cutter is fixedly connected on upper tool post, power source drives upper tool post to move reciprocatingly in vertical direction by transmission mechanism, upper tool post is when moving downward, driving force is combined with gravity, form larger shearing inertia, make in cutter and bottom knife closing course sheet shearing.What in this plate shearing machine, cutter adopted is the straight cutter of rectangle, and what bottom knife adopted is V word cutter.In long-term practice, find, utilize the deflection of the plate shears otch that plate shearing machine of the prior art cuts very large, sheared edge glacing flatness is generally about 2mm-2.5mm.This sheared edge glacing flatness, for the parts of the higher electronic product of required precision, automobile product, is underproof, does not reach product requirement.And what adopt due to bottom knife of the prior art is that gradient is the V word cutter of 3 °, and cutter adopts, be the straight cutter of rectangle, cause the interposition of the sheet material after shearing to be equipped with the thorn that becomes mildewed.This technological deficiency is needed badly and is resolved.
Utility model content
For above-mentioned deficiency of the prior art, the utility model main purpose is to provide a kind of scissors for plate shearing machine, can effectively reduce the deflection of sheet material after plate and reduce burr.
For achieving the above object, the technical solution adopted in the utility model is: a kind of scissors for plate shearing machine, comprising: cutter and bottom knife, and the blade of described cutter and described bottom knife is all V-shape; The gradient of the blade of described cutter and bottom knife is identical; The blade of described cutter comprises the first contact-making surface and the second contact-making surface, and the gradient of described the first contact-making surface and the second contact-making surface is 1-5 °.Be different from cutter of the prior art and adopt the straight cutter of rectangle, bottom knife to adopt the way of V word cutter, cutter and bottom knife for the scissors of plate shearing machine in the utility model all adopt V-shape blade, to reduce the deflection of sheet material.
Preferably, the first contact-making surface of described cutter and the gradient of the second contact-making surface are 1-3 °.
The gradient of the blade of the cutter described in the utility model and bottom knife is identical, and described bottom knife comprises the first contact-making surface and the second contact-making surface, therefore the first contact-making surface of the blade of described bottom knife and the gradient of the second contact-making surface are also 1-3 °.
Preferably, the thickness of described cutter and bottom knife is 20mm-30mm.For guaranteeing certain shearing force, in the utility model, the thickness of cutter and bottom knife is preferably made as 20mm-30mm, certainly, in actual production, can make suitable adjustment to the thickness of cutter and bottom knife, to meet need of production for the different sheet material of processing.
The broadband of the cutter described in the utility model and bottom knife is generally determined according to the width of the sheet material of required processing, generally between 800mm-1850mm.The cutter of the scissors described in the utility model and the height of bottom knife are generally determined according to the model of plate shearing machine, generally between 80mm-100mm.
The utility model is by the improvement to the shear-blade of plate shearing machine, reduced cutter and the bottom knife volume under pressure in shear history, the deflection of sheet material is alleviated, the deflection that adopts the sheared edge of the sheet material after scissor cut described in the utility model is 0.5mm, and the amount of the burr of plate shears otch minimizing simultaneously and burr length reduce.Utilize the sheet deformation amount of scissor cut described in the utility model little, precision is high, can meet the industry requirement higher to sheet material required precision, as electronic product, auto parts and components processing etc.
The beneficial effects of the utility model are: the utility model is for the scissors of plate shearing machine, can effectively reduce the deflection of sheet material after plate and reduce burr.
