Abstract
The utility model belongs to the technical field of hammer heads of crushing equipment. A high-vanadium high-speed steel composite hammer head provided by the utility model is composed of the composite integration of a head part (1) composed of high-vanadium high-speed steel, and a hammer handle (2) composed of 35CrMo. The hammer handle which is cast in advance is heated to a certain temperature, and is cast together with high-vanadium high-speed steel alloy liquid. The main hard phase in the high-vanadium high-speed steel of the composite hammer head structure provided by the utility model is VC of which the micro-hardness is as high as HV3000 and is much higher than the micro-hardness of high-chromium cast iron, can effectively resist the scratch of materials and has good wear resistance and good toughness. The hammer handle is made from 35CrMo which has good toughness, and can resist strong impact when an impact hammer works. The composite body structure ensures the high wear resistance of the hammer head, and makes the hammer head have good toughness. The service life is five to eight times of common high-manganese steel, and is two to five times of high-chromium cast iron. The head part and the hammer handle are well combined in a metallurgical mode. The utility model has the advantages of high safety and no rupture phenomenon.
Description
Affiliated technical field
The utility model belongs to disintegrating apparatus tup technology, mainly proposes a kind of high-vanadium high-speed steel composite hammer head.
Background technology
At present, the material of the tup in the disintegrating apparatus mainly adopts potassium steel series, steel alloy series, alloy cast iron series, rich chromium cast iron series.Wherein, potassium steel has good toughness, but its initial hardness low (HB229 following), under middle low stress working condition or grinding charge material when softer, is difficult to abundant work hardening, and wearability is very low.Rich chromium cast iron is domestic and international wearability of a generally acknowledging material preferably, but for the operating mode than high impact loads, the toughness deficiency.The high-speed steel anti-wear performance is fine, but its cost height, the manufacturing process complexity generally only is used to make cutter.
Summary of the invention
The purpose of this utility model is to propose a kind of high-vanadium high-speed steel composite hammer head, solves that traditional tup potassium steel wearability is relatively poor, rich chromium cast iron toughness deficiency, can not effectively resist the problem that hard material scratches.
The utility model is finished its invention task by the following technical solutions: tup comprises hammer handle and head, it is the head that is made of high-vanadium high-speed steel and is made of the compound one of hammer handle that 35CrMo constitutes, wherein, the composition of high-vanadium high-speed steel is C:1.8～2.8, V:10～16, Cr:1～3, Mo:0.8～12, Ni:0.5～1.5, surplus are steel.
The composite hammer head structure that the utility model proposes, the main hard in the high-vanadium high-speed steel are VC mutually, and its microhardness far above the microhardness of rich chromium cast iron, can effectively resist the scuffing of material up to HV3000, and wearability and toughness are good.Hammer handle adopts the 35CrMo of good toughness, the intense impact in the time of can resisting jump bit work, and complex structure has not only guaranteed the high abrasion of tup but also make it have good toughness, be 5-8 times of common potassium steel service life, the 2-5 of rich chromium cast iron doubly, and is safe and reliable, phenomenon of rupture can not take place.
Description of drawings
Accompanying drawing 1 is the utility model section of structure.
Among the figure, 1, head, 2, hammer handle.
The specific embodiment
The accompanying drawing that provides is in conjunction with the embodiments further specified its structure:
As shown in Figure 1, tup comprises head 1 and hammer handle 2, its hammer handle and head are complex structure, i.e. the head 1 that constitutes by high-vanadium high-speed steel and constitute by the hammer handle 2 compound one that 35CrMo constitutes, wherein, the composition of high-vanadium high-speed steel is: carbon (C): 1.8～2.8, vanadium (V): 10～16, chromium (Cr): 1～3, manganese (Mo): 0.8～12, nickel (Ni): 0.5～1.5, surplus is a steel.35CrMo is common material commonly used.
Claims (1)
1, a kind of high-vanadium high-speed steel composite hammer head has head (1) and hammer handle (2), it is characterized in that: head (1) that is made of high-vanadium high-speed steel and the compound one of the hammer handle (2) that is made of 35CrMo constitute.
