Abstract
The utility model discloses a composite cutting edge for shearing a hot steel billet, which comprises a concave cutting edge and a convex cutting edge, each cutting edge comprises two parts of a cutting edge body 1 and an edge 2 stuck on the cutting edge body, wherein each cutting edge body 1 is a 42CrMo forged piece, and the material of each edge 2 is H13. The H13 materials of the edges on the original cutting edge bodies can be replaced after abrasion, and the cutting edge can be used continually, thereby avoiding scraping the whole cutting edge and further prolonging the service life of the cutting edge. Simultaneously, as the price of the 42CrMo forged pieces of the cutting edge bodies is lower than that of the H13 materials, the cost of the concave and the convex cutting edges is reduced from 19000 yuan to 9000 yuan, thereby reducing the cost. The composite cutting edge can significantly prolong the service life of the cutting edge and reduce the manufacturing cost of the cutting edge.
Description
Technical field
The utility model relates to the rolling metal spare part, relates in particular to a kind of composite shearing blade for shearing hot steel billet.
Background technology
In steel billet hot shears when work,, the temperature of shearing steel billet is higher than 650 ℃, and sometimes even reach 1100-1250 ℃, the maximum temperature of hot-shear blade cutting edge can reach more than 700 ℃, and cutting edge is in water-cooled situation or cooling apace in air.Therefore require the material of hot-shear blade cutting edge to have higher high temperature wear resistant, high temperature resistance to impact and cold-resistant thermal fatigue property.At present, generally the hot-shear blade of Shi Yonging is whole steel alloy cutting edge, and cutting edge is whole with the grinding shaping of H13 material quenching back, and the cost of producing a secondary concavo-convex compound cutting edge is greatly about about 10,000 9 thousand yuan.But owing to the cutting edge part of cutting edge will be scrapped after may wear to a certain degree, and this material of H13 just can not utilize after quenching again, has therefore caused great waste.
Summary of the invention
Problem to be solved in the utility model provides a kind of compound cutting edge, and it can prolong the service life of cutting edge significantly, and has reduced the manufacturing cost of cutting edge.
A kind of composite shearing blade for shearing hot steel billet of the present utility model is made up of recessed cutting edge and protruding cutting edge, and recessed cutting edge and protruding cutting edge are formed by cutting edge body 1 and cutting edge 2 two parts that are bonded on the cutting edge body.Wherein cutting edge body 1 is the 42CrMo forging, and cutting edge 2 materials are H13.
Behind the H13 of cutting edge fret wear, can on original cutting edge body, change the material of cutting edge, cutting edge continues to use, and can not cause the integral body of cutting edge to scrap, thereby has prolonged the service life of cutting edge.Simultaneously, because the 42CrMo forging of cutting edge body is lower than the price of H13 material, therefore this novel concavo-convex being cut into originally drops to 9,000 yuan by 1.9 ten thousand yuan, has reduced cost.
Description of drawings
Fig. 1 is the schematic diagram of the recessed cutting edge of the compound cutting edge of the utility model;
Fig. 2 is the schematic diagram of the protruding cutting edge of the compound cutting edge of the utility model.
The specific embodiment
The utility model is that existing all-in-one-piece recessed cutting edge, protruding cutting edge all are divided into cutting edge body 1, are bonded at cutting edge 2 two parts on the cutting edge body.Cutting edge body 1 42CrMo forging wherein, cutting edge 2 material H13.Adding man-hour, will be machined directly to size after the modifier treatment of cutting edge body, cutting edge is made Quenching Treatment after partly staying the mill amount, after with happy safe 680 glue pressurization both being bonded together, cutting edge is ground to last size again.The big 10mm of the cutting edge cutting edge part aspect ratio cutting edge maximum amount of regrinding, remainder is a body.
Behind the H13 of cutting edge fret wear, can on original cutting edge body, change the material of cutting edge, cutting edge continues to use, and can not cause the integral body of cutting edge to scrap, thereby has prolonged the service life of cutting edge.
Simultaneously, because the 42CrMo forging of cutting edge body is lower than the price of H13 material, therefore this novel concavo-convex being cut into originally drops to 9,000 yuan by 1.9 ten thousand yuan, has reduced cost.And the cutting edge body can also melt down again to forge to change and do other products and utilize, reduced waste.
