Abstract
The utility model discloses a hammer disc of a hammer crusher. The hammer disc comprises a core part (1) and an outer edge (2), wherein the core part (1) is made of a common medium carbon steel plate, the outer edge (2) is made of manganese chromium wear-resistant alloy, and the outer edge (2) is formed on the outer circumference of the core part (1) in a composite casting manner, so as to form a whole hammer disc, the hammer disc is provided with a spindle hole (3) and a hammer head pin shaft hole (4). The hammer disc disclosed by the utility model is characterized in that a wedge-shaped groove (5) is turned on an excircle of the core part (1), the wedge-shaped groove (5) is arranged in the middle of the width of the hammer disc and is big inside and small outside, and one melon seed type embedded hole (6) is respectively additionally arranged at the two sides of the hammer head pin shaft hole (4). The hammer disc disclosed by the utility model has a simple structure and firm combination, wear-resistant material of the outer edge is effectively prevented from cracking and falling off, the whole hammer disc has high strength, toughness and wear resistance, the service life of the hammer disc is 8-12 times longer than that of a common product, maintenance cost is obviously reduced, and operation rate is improved.
Description
Technical field
The utility model relates to hammer mill, is specifically related to the wear-resisting hammer dish of a kind of hammer mill.
Background technology
The hammer mill that present metallurgy, mine, building materials, coal, chemical industry, water conservancy, water power etc. use; During its hammer dish mostly adopts, low carbon steel plate; The outer rim position is with wear resistance electrode built-up welding 8-10mm; Every built-up welding once generally only can be used just needed built-up welding again in 7-15 days, and each built-up welding needs 2-3 days, and maintenance work is very heavy.Also have and adopt the low carbon steel plate nitrogencase hardening to handle,, prolongation is arranged slightly service life at initial stage, have to return the old road of wear resistance electrode built-up welding after the quench-hardened case wearing and tearing because the depth of quenching is thinner.The someone adopts high manganese steel casting in addition, and cost is higher, and processing is difficulty relatively.
Summary of the invention
The purpose of the utility model is: provide a kind of hammer mill wear-resisting hammer dish; Its manufacturing cost is lower, easy to process, long service life, maintenance cost is low, operation rate is high, to the production applying unit save energy and reduce the cost, increasing economic efficiency has the appreciable impact effect.
The technical solution of the utility model is: this hammer dish comprises core and outer rim; Core adopts the common medium-carbon steel plate, and outer rim adopts manganese chromium antifriction alloy, and the composite casting outer rim constitutes whole hammer dish on the excircle of core; Establish spindle hole and hammer pin axis hole on the hammer dish; It is characterized in that: core cylindrical car is carved the type groove, and it is middle big outer little that the type groove of carving is positioned at hammer dish width, and the both sides of hammer pin axis hole is set up a melon seeds type embedded hole respectively.
Wherein, outer edge thickness is greater than core thickness.
The utility model is simple in structure, in conjunction with firmly, effectively prevents outer rim high-abrasive material cracking, comes off; Whole hammer dish has had intensity, toughness and high-wearing feature concurrently; The hammer dish than the high 8-12 of mill run has doubly significantly reduced maintenance cost service life, has improved operation rate.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the cut-away view of Fig. 1.
Fig. 3 is the local enlarged diagram of Fig. 2.
Among the figure: 1 core, 2 outer rims, 3 spindle holes, 4 hammer pin axis holes, 5 carve the type groove, 6 melon seeds type embedded holes.
Concrete implementation
Shown in Fig. 1-3, this hammer dish comprises core 1 and outer rim 2, and core 1 adopts the common medium-carbon steel plate; Outer rim 2 adopts manganese chromium antifriction alloy; Composite casting outer rim 2 constitutes whole hammer dish on the excircle of core 1, establishes spindle hole 3 and hammer pin axis hole 4 on the hammer dish, and it is characterized in that: core 1 cylindrical car is carved type groove 5; Carve type groove 5 and be positioned in the middle of the hammer dish width for a short time greatly outward, the both sides of hammer pin axis hole 4 is set up a melon seeds type embedded hole 6 respectively.
Wherein, outer rim 2 thickness are greater than core 1 thickness.
Add man-hour; Core 1 is the common medium-carbon steel plate, and first roughing spindle hole 3 and hammer pin axis hole 4 stay allowance for finish; Core 1 cylindrical car is carved type groove 5; Cut melon seeds type embedded hole 6, composite casting high abrasion manganese evanohm becomes outer rim 2 on the excircle of core, is refined to the broken hammer dish size that requires of all size hammer at last.
Claims (2)
1. hammer mill hammer dish; This hammer dish comprises core (1) and outer rim (2); Core (1) adopts the common medium-carbon steel plate, and outer rim (2) adopts manganese chromium antifriction alloy, and composite casting outer rim (2) constitutes whole hammer dish on the excircle of core (1); Establish spindle hole (3) and hammer pin axis hole (4) on the hammer dish; It is characterized in that: core (1) cylindrical car is carved type groove (5), carves type groove (5) and is positioned in the middle of the hammer dish width for a short time greatly outward, and the both sides of hammer pin axis hole (4) is set up a melon seeds type embedded hole (6) respectively.
2. hammer mill hammer dish according to claim 1 is characterized in that: wherein, outer rim (2) thickness is greater than core (1) thickness.
