Abstract

The utility model discloses an improved composite alloy disc knife, which is used for the shearing machining of various plates in a metallurgy industry. A substrate is embedded with a composite material which serves as a cutting edge, wherein the composite material is a hard alloy; and the substrate has a split structure. A new cutting edge can be machined by secondarily grinding a scrapped imported disc knife; and the internal substrate adopts the split structure, and is compounded with low-cost steel by a special compounding technology to remanufacture the disc knife with high performance. By the utility model, under the condition of ensuring the performance of the disc knife, the scrapped imported or homemade high-quality knife is taken as a raw material, the failure type and working condition of the disc knife are comprehensively taken into account, the characteristics of high hardness and abrasive resistance of imported alloy steel are fully utilized, the split substrate is internally compounded by secondary grinding and machining, and the performance of a precious alloy is maximally developed, so that the comprehensive performance of the knife can be improved, and cost can be effectively decreased at the same time; and the improved composite alloy disc knife has the advantages of high performance, low cost, high yield and the like, and is easy to machine.

Description

Modified form alloy complex disc blade

Technical field

The utility model relates to the processing of metallurgy industry sheet material and uses circle shear, is a kind of composite blade that is used on the cut edge circle shear specifically.

Background technology

In the modern steel industry, cut edge circle shear is widely used in iron and steel, the production of non-ferrous metal processing strip, like cold-rolling mill, side cut rewinding unit, crop shears, stretch-bending straightening unit etc.Its purposes has two kinds, and a kind of is to be used for the metal plate and belt production process to cut away strip both sides raw edges, in order to later process production; Another kind is to be cut into the desired width of final products.And cutting disc is the critical component that it realizes function; The manufacturing of cylinder blade mostly adopts the monoblock raw material to process (selection is variant) both at home and abroad at present; And homemade cylinder blade performance is exactly the difference of material property not as the key factor of import blade, secondly is Technology for Heating Processing.Therefore the raw material of selecting for use are one of effective ways that improve the circle shear performance.But select the import alloy material for use, product cost will increase thereupon.Now also have the cylinder blade of few part specific use to adopt carbide alloy or other material edge cover technology, but its difficulty of processing is big, cost is high, and yield rate is low, and scope is restricted.

Summary of the invention

For overcoming the deficiency of prior art, the goal of the invention of the utility model is to provide a kind of modified form alloy complex disc blade, and is compound through special technique, and to improve the cutting disc combination property, realization reduces cost, aim of saving.

For realizing above-mentioned purpose, the technical scheme of the utility model is: stud with composite bed on the matrix as cutting edge, composite bed is a carbide alloy, and matrix is a split-type structural.

The cutting edge position utilizes written-off import cylinder blade, through the secondary reconditioning, and the cutting edge that processing makes new advances; Inner base adopts split-type structural, designs two sloping platform rank at inner ring, through with the cooperating of alloy part, can bear larger axis to power; Select cheap steel for use, compound through special complex technique, to change a social system out the cylinder blade of excellent performance.

The utility model compared with prior art, under the situation that guarantees the cutting disc performance, through being raw material to written-off import or homemade high-quality blade; Take all factors into consideration the failure mode and the duty thereof of cutting disc; Make full use of the characteristics that import steel alloy hardness is high, wearability is good, through secondary reconditioning, processing, inner compound split type matrix; Perform to the performance of valuable alloy ultimate attainment; When realize promoting the combination property of blade, can effectively reduce cost, have that performance is good, cost is low, be prone to processing, yield rate advantages of higher.

Description of drawings

Fig. 1 is the structure diagram of the utility model;

Fig. 2 is reconditioning, the improvement pre-structure figure of the utility model.

The specific embodiment

As shown in Figure 1, the utility model is changed a social system composite bed 1 earlier: mill oblique angle, two ends, middle mill groove, reconditioning cutting edge again, again according to changing a social system specification processing matrix 3: require the chamfering grinding two ends outside, the middle groove of processing; Composite bed 1 passes through adhesive linkage 2 strong bond together with matrix 3, and after the compound completion, whole reconditioning is to reach dimensions and high service precision.The import high duty alloy material that the described composite bed 1 of the utility model is an excellent performance also can be other Hardmetal materials.

Thick, the fine finishining of the utility model need a plurality of processes, with maximum assurance precision, and after each machined, all will carry out The heat treatment of oil oven timeliness, to eliminate the internal stress that machined produces.

As shown in Figure 2, be blade figure before written-off reconditioning, the improvement.
