Abstract
The utility model discloses a wear -resisting hammer is used to breaker, set up the embedment in the tup including tup and at least one embedding, the tup is the cast steel body, the embedment is the high chromium cast iron alloy body, the high chromium cast iron alloy body is for being provided with the porous structure who is used for forming the permeability hole of steel -cast molten steel infiltration, setting up the embedment through imbedding in the tup, being porous structure on the embedment, when the molten steel of the cast steel body was cast, the molten steel was around the embedment and in permeating the income permeability hole for form strong mechanical interlocking between the cast steel body and embedment, joint strength is high, thereby improves the holistic structural strength of wear -resisting hammer, wearability and anti high -speed impact property, moreover, makes the utility model discloses the wear rate is low, long service life.
Description
Technical field
The utility model relates to Mechanical Crushing field, particularly a kind of disintegrating machine Wear resisting hammer.
Background technology
Quartering hammer is the core component of disintegrating machine, be mainly used in break mined material raw material, cracking hammer head High Rotation Speed in disintegrating machine runs, and between raw mineral materials in impact several times impact friction process, cracking hammer head head is made to be diminished by progressively wearing and tearing and lose efficacy and scrap, length in service life due to cracking hammer head directly affects the fragmentation quality of material and production efficiency and cost, need frequently more to renew tup to meet the needs of production, so broken industry is constantly making great efforts the tup manufacturing the high life always.
Therefore, need to improve existing disintegrating machine hammer, make its structural strength high, long service life.
Utility model content
In view of this, the utility model provides a kind of disintegrating machine Wear resisting hammer, and its structural strength is high, and anti-high speed impact ability is strong, long service life.
Disintegrating machine Wear resisting hammer of the present utility model, comprise tup and embed with at least one the insert be arranged in tup, described tup is cast steel body, described insert is high-chromium cast iron alloy body, and described high-chromium cast iron alloy body is the loose structure of the permeability hole of the infiltration of molten steel be provided with for the formation of cast steel.
Further, permeability hole described in each includes fluid inlet and fluid issuing, and permeability hole forms alveolate texture jointly.
Further, tup is the cast steel body be made up of high manganese steel material.
Further, Wear resisting hammer also comprises the hammer handle with the cast molding of tup one, and hammer handle is provided with suppending hole, and suppending hole is 300-320mm to tup end distance.
Further, suppending hole exradius is 70mm.
Further, hammer handle and tup junction are for seamlessly transitting structure.
The beneficial effects of the utility model: disintegrating machine Wear resisting hammer of the present utility model, by being embedded at tup, insert is set, insert is loose structure, when the molten steel of cast steel body is cast, molten steel is around insert and infiltrate through in permeability hole, make to be formed between cast steel body and insert mechanical interlocked by force, bonding strength is high, thus the structural strength of raising Wear resisting hammer entirety, wearability and anti-high-speed impact property, and, make the utility model wear rate low, long service life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the utility model structural representation;
Fig. 2 is the insert schematic cross-section in the utility model.
Detailed description of the invention
Fig. 1 is for being the utility model structural representation, Fig. 2 is the insert schematic cross-section in the utility model, as shown in the figure: the disintegrating machine Wear resisting hammer of the present embodiment, comprise tup 1 and embed with at least one the insert 2 be arranged in tup 1, described tup 1 is cast steel body, described insert 2 is high-chromium cast iron alloy body, and described high-chromium cast iron alloy body is the loose structure of the permeability hole 3 be provided with for the formation of the infiltration of molten steel of cast steel; The utility model is when making, first melting high-chromium cast iron alloy liquid, high-chromium cast iron alloy liquid is cast into insert 2 blank, then by insert 2 blank by being processed into insert 2, insert 2 is put in formwork, then casting tup 1 and hammer handle, molten steel, flowing into through permeability hole 3 while insert 2, forms good bonding strength.
In the present embodiment, described in each, permeability hole 3 includes fluid inlet and fluid issuing, and permeability hole 3 forms alveolate texture jointly; Tactical rule, easily manufactures, and meets the needs of infiltration of molten steel.
In the present embodiment, tup 1 is the cast steel body be made up of high manganese steel material; Wearability is good.
In the present embodiment, Wear resisting hammer also comprises the hammer handle 4 with the cast molding of tup 1 one, hammer handle 4 is provided with suppending hole 5, and suppending hole 5 is 300-320mm to tup 1 end distance; Discharging-material size improves, and substantially improves the crushing effect of plate-hammer crusher, improves output.
In the present embodiment, suppending hole 5 exradius is 70mm.
In the present embodiment, hammer handle 4 and tup 1 junction 6 are for seamlessly transitting structure; Prevent stress from concentrating.
In addition, the corner of insert 2 is round-corner transition, forms good molten steel covered effect.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
