Abstract
The utility model belongs to the field of a steel shearing device, particularly a new circular shear blade for circular shears. The utility model is particularly suitable for shearing steel products, such as cold-rolled strip steel. The circular shear blade for circular shears is composed of a circular shear blade body and a wear-resistant nanometer material layer coated on the blade edge of the circular shear blade body, wherein the wear-resistant nanometer material layer comprises an annular belt wear-resistant nanometer material layer coated on the outer circumferential surface of the circular shear blade body, and outside annular ring wear-resistant nanometer material layers coated on the surfaces of circular discs on both sides of the circular shear blade body. The cut surface of strip steel shorn by the circular shear blade for circular shears is smooth and has no burr; accordingly, a shearing procedure on the production line of cold-rolled strip steel is omitted; accordingly, the labor productivity is improved, and the energy consumption is reduced; in addition, the utility model notably extends the service life of the shear blade, decreases the times of circular shear blade replacement, improves the labor productivity and reduces the cost.
Description
Technical field
The utility model belongs to the steel cutting apparatus field, and the novel rotary cutter edge that particularly a kind of circle shears is used is particularly useful for shearing cold-strip steel and so on steel product.
Background technology
In steel rolling is produced, particularly in the cold rolled strip steel production line, generally adopt circle shears to come the shear band steel, owing to be under cold conditions, to shear, the hardness of band steel, intensity are all than higher, and is therefore also bigger to the wearing and tearing of cutting edge, so need often to change cutting edge, once test the method that such as carburizing, improves the cutting edge anti-wear performance, but do not receive due effect.Another problem that adopts conventional cutting edge to bring is the shear surface out-of-flatness, often will carry out secondary shearing in steel rolling production-line, shears the burr that is caused first so that eliminate.
Summary of the invention
It is good that the purpose of this utility model provides a kind of anti-wear performance, long service life, the novel rotary cutter edge that the circle shears that shearing quality is good is used.
Novel rotary cutter edge according to circle shears of the present utility model is used comprises the rotary cutter edge body, it is characterized in that being made up of described rotary cutter edge body and the nanometer antiwear material layer that is coated in this rotary cutter edge body knife edge position.
According to the novel rotary cutter edge that circle shears of the present utility model is used, described nanometer antiwear material layer is made up of the exterior annular circle nanometer antiwear material layer that is coated in the endless belt nanometer antiwear material layer on the rotary cutter edge body outer circumference surface and be coated on the disc surfaces of rotary cutter edge body both sides.
The novel rotary cutter edge that adopts circle shears of the present utility model to use; improve three times than plain disk cutting edge its service life; level and smooth, the no burr of the otch of band steel; need not to carry out secondary shearing; therefore not only significantly reduce the number of times of changing rotary cutter edge and changed the downtime that rotary cutter edge caused; and cancelled the secondary shearing operation, thereby utilization rate of equipment and installations and labor productivity have been improved.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present utility model.
As shown in Figure 1, the novel rotary cutter edge that circle shears of the present utility model is used comprises rotary cutter edge body 3, it is characterized in that being made up of described rotary cutter edge body 3 and the nanometer antiwear material layer that is coated in this rotary cutter edge body knife edge position.
As shown in Figure 1, described nanometer antiwear material layer is formed by being coated in endless belt nanometer antiwear material layer 1 on rotary cutter edge body 3 outer circumference surfaces and the exterior annular circle nanometer antiwear material layer 2 that is coated on the disc surfaces of rotary cutter edge body both sides.
Actual tests proves, uses bright and clean, the no burr of band steel otch of rotary cutter edge shearing of the present utility model, has not only reduced one cutting operation of cold rolled strip steel production line, has also reduced the shearing loss, and be significantly improved the service life of rotary cutter edge.Because the nanometer antiwear material coating as thin as a wafer, all have no effect for the installation of circle shear, use etc.
Claims (2)
1, the novel rotary cutter edge used of a kind of circle shears comprises the rotary cutter edge body, it is characterized in that being made up of described rotary cutter edge body and the nanometer antiwear material layer that is coated in this rotary cutter edge body knife edge position.
2, the novel rotary cutter edge used of circle shears according to claim 1 is characterized in that described nanometer antiwear material layer is made up of the exterior annular circle nanometer antiwear material layer that is coated in the endless belt nanometer antiwear material layer on the rotary cutter edge body outer circumference surface and be coated on the disc surfaces of rotary cutter edge body both sides.
