Abstract

The utility model relates to a kind of V-type head wearing piece for hammer head of hammer crusher, comprise body, described body is rectangular structure, be V-type head in the lower end of described body, the left and right side of body upper part arranges symmetrical fixture conjunction structure respectively, described fixture conjunction structure comprises the first recessed groove and the second recessed groove, described in comprise the first recessed groove and the open slot of the second recessed groove all for being made up of hypotenuse and base.The V-type head wearing piece that the utility model provides makes that hammer head of hammer crusher is wear-resisting, long service life, prevents wearing piece from coming off from tup simultaneously.

Description

A kind of V-type head wearing piece for hammer head of hammer crusher
Technical field
The utility model relates to a kind of V-type head wearing piece for hammer head of hammer crusher.
Background technology
The principle of hammer head breaker is that the material utilizing the tup of High Rotation Speed and eminence to fall bumps against material fragmentation.Tup is the main grinding component of hammer mill, and it has larger speed and inertia force in the course of the work.Therefore require that the material manufacturing tup not only should possess enough impact resistances, excellent wearability, and fracture must be prevented.The tup of current use adopts potassium steel to make.The potassium steel of as-cast structure is very crisp, and show as wearability lower, service life is shorter.
Chinese patent CN101773864A discloses a kind of durable hammer of crusher, and this tup is formed to sell by pin-and-hole and hammer handle to be connected, although change conveniently, but easily loosen in the tup course of work, tup easily comes off.In addition, the Double-metal composite hammer had been reported, hammer handle adopts medium and low carbon steel, tup wearing part is rich chromium cast iron, carbon steel good toughness, non-frangibility can be given full play to, the advantage that rich chromium cast iron hardness is high, wearability is good, but the danger having that rich chromium cast iron easily occurs to come off along faying face, jeopardize device security.Bargh is 1-2 days the potassium steel tup replacement cycle, and the replacement cycle is short, and replacing tup affects very large on production cost and the performance of enterprises.
Utility model content
The purpose of this utility model is to provide a kind of V-type head wearing piece of tup of wear-resisting, slip-off preventing, uses it for hammer head of hammer crusher, can solve the problem that in prior art, hammer head of hammer crusher easily comes off, the replacement cycle is short.
The technical solution of the utility model is, a kind of V-type head wearing piece for hammer head of hammer crusher is provided, comprise wearing piece body, described body is rectangular structure, be V-type head in the lower end of described body, the left and right side of body upper part arranges symmetrical fixture conjunction structure respectively, and described fixture conjunction structure comprises the first recessed groove and the second recessed groove, described in comprise the first recessed groove and the open slot of the second recessed groove all for being made up of hypotenuse and base.
Further, between the first recessed groove and the second recessed groove, platform is set.
Further, the first recessed groove is arranged to parallel with body upper surface with the base of the second recessed groove.
The utility model adopts potassium steel tup to combine with hard alloy wear resistant parts, and casting process makes potassium steel tup and hard alloy wear resistant parts form metallurgical binding.Wearing piece bottom surface is groundwork face, bottom surface is arranged to V-type head, makes the fragmentation of wearing piece to material better.Wearing piece designs two recessed grooves, and the shape of recessed groove is designed to right-angled trapezium and right angled triangle respectively.In the process of the broken material of reality, impacted mutually by the tup of broken material with High Rotation Speed, as during with forward impact, its impulsive force is all converted into the compression to the flat side of a hammer, tup metal surface is made to produce plastic deformation and micro-crack, Crack Extension in repeated multiple times flow situation, metal be squeezed formed fragment come off, cause impact wear, when impulsive force is large, tup surface can produce work hardening, and hardness is comparatively large, and hardened layer is darker.As impacted with certain impact angle, then impulsive force be decomposed into perpendicular to the flat side of a hammer normal stress and be parallel to the tangential stress of the flat side of a hammer, tup coating metal is produced to micro-cutting, washes away, makes honing, formation cuts groove.Pass through optimal design, make to form a sharp angle by a horizontal line and an oblique line in recessed groove, the effect forming chucking power between tup and wearing piece can be made better, being conducive to hard alloy wear resistant parts is combined tightr with potassium steel tup, avoid under the shock loading of high strength, wearing piece and potassium steel hammer body come off.This V-type head wearing piece and tup compound make crushing efficiency higher, longer service life.The convex-concave degree that platform decreases wearing piece surface is to a certain extent set between the first recessed groove and the second recessed groove, makes cast molding easy, also can form better metallurgical binding effect.In addition, for making wearing piece shaping and be convenient in demoulding in actual production, the chamfering of certain radian is provided with at edge.
Technique effect of the present utility model: recessed groove the design combination that makes tup and wearing piece more firm, solve in tup use procedure and need the frequent problem changed; The fragmentation that makes of the V-type head bottom wearing piece also promotes greatly.The service time of the V-type head wearing piece tup that the utility model provides is 20-30 times of common potassium steel tup, and preparation cost improve only 30%, greatly increases the economic benefit of enterprise.
Accompanying drawing explanation
Fig. 1 is the stereogram of the V-type head wearing piece that the utility model provides.
Fig. 2 is the end view drawing of the V-type head wearing piece that the utility model provides.
Fig. 3 is the installation diagram of wearing piece in hammer head of hammer crusher.
Detailed description of the invention
Below in conjunction with accompanying drawing 1-3, further illustrate the V-type head wearing piece for hammer head of hammer crusher that this detailed description of the invention provides, tup is Mn13Cr2 high manganese steel material, and wearing piece is TM52 Hardmetal materials.As shown in Figure 1, body 11 is set to rectangular structure, V-type 1 is set in the lower end of body 11, the left and right side on body 11 top arranges symmetrical fixture conjunction structure respectively, described fixture conjunction structure comprises the first recessed groove 2 and the second recessed groove 3, the open slot that first recessed groove 2 and the second recessed groove 3 form by base and hypotenuse, the first recessed groove 2 is all parallel with the upper surface of body 11 with the base of the second recessed groove 3.Figure 2 shows that the end view drawing of wearing piece one end, between the first recessed groove 2 and the second recessed groove 3, platform 4 is set.It is the installation site of wearing piece in hammer head of hammer crusher shown in Fig. 3.
The body 11 of the V-type head wearing piece that this detailed description of the invention obtains is rectangular structure, and cuboid dimensions is 40 mm × 20, mm × 34 mm; The length that the length direction of body 11 (long 40 mm) arranges the first recessed groove 2 and the second recessed groove 3, two recessed groove is equal, is 34 mm, not the length direction of through body 11; The stereochemical structure of V-type head is straight triangular prism, and the bottom surface of its side and body 11 is coplanar, and its bottom surface is isosceles triangle, and the height of isosceles triangle is 7 mm; Wide 2.5 mm of platform 4 between first recessed groove 2 and the second recessed groove 3; Whole wearing piece heavily about 0.17 kg.
Be combined with the tup of potassium steel by above-mentioned obtained wearing piece with casting process, the both sides of tup front end install three wearing pieces respectively, and obtained tup is used for hammer mill, found that wearing piece is combined with tup closely, do not come off, crushing efficiency improves 20%, is about 25 days service life.
