Abstract
The utility model relates to a hammer type crusher device used in mines, in particular to a U-shaped groove surfacing wear-resistant hammer for mine underground crushers. A mine underground hammer type crusher uses a crushing shaft to drive a crushing hammer to rotate at high speed so as to crush large-sized coals into required lumpiness. A hammer is an important quick-wear part of the crusher and is required to be provided with high impact resistant capacity and wear resistance. Normal method and technique which include that the hammer is forged by alloy structural steel and that a wear-resistant layer is arranged on a wearing portion of the hammer by means of surfacing are simple, have convenient application and realize a certain effect, however, the surfacing wear-resistant layer is thin and has short service life, thereby being unable to finely resolve problems of wear resistance and short service life of the hammer. A U-shaped groove surfacing wear-resistant hammer for crushers adds a U-shaped groove structure on the wearing portion on the top portion of the hammer, highly wear-resistant alloy surfacing cored wires are filled into the groove, surfacing is performed on the groove to form a required shape, and then the wear-resistant layer is arranged on the wearing portion (I area) of the hammer by means of surfacing, thereby having simple and reliable technique and achieving purpose of prolonging service of the hammer.
Description
Technical field
The utility model relates to a kind of colliery hammer crushing machine, specifically a kind of disintegrating machine U-lag build-up wear-resistant tup.
Background technology
The hammer mill operation principle is in the elevating conveyor operation process under the coal mine, the broken shaft of disintegrating machine drives the rotation of quartering hammer head height speed, the coarse coal impact cutting is broken into required lumpiness, and be transported on the ribbon conveyer through elevating conveyor, avoid injuring conveyer belt by a crashing object because of the raw coal lumpiness is excessive and in course of conveying, taking place from rolling phenomenon.
Tup is the important consumable accessory in the disintegrating machine, requirement has high impact resistance and wearability, usually the tup that adopts is forged by structural alloy steel, and at tup abrading section surface overlaying wearing layer, this method technology is simple, and it is convenient to use, obtained certain effect, but the wearing layer of built-up welding is thin in this way, and service life is short, can not fine solution tup short problem friction durability.
Summary of the invention
The purpose of this utility model provides a kind of disintegrating machine U-lag build-up wear-resistant tup, wearability and the service life that can effectively improve tup.
The technical scheme that the utility model adopted is: comprise that tup body and surface overlaying layer constitute, it is characterized in that: the abrading section district has U-lag at the tup top, in U-lag, there is layering to fill the high-wear-resistant alloy overlay cladding of built-up welding, form the U-lag overlay cladding, on surface, district, tup abrading section high-wear-resistant alloy build-up wear-resistant floor is arranged, form the surface overlaying layer.
The beneficial effects of the utility model are that the wearing layer that has solved with the original recipe built-up welding approaches, if increase the problem that wearing layer thickness then can cause wearing layer to crack again.After the U-lag built-up welding is opened in employing, can make overlay cladding thickness increase by 4 times, prevent from simultaneously to thicken the cracking problem that causes, tup is prolonged friction durability greatly because of overlay cladding.This method is easy to process, and cost is low, and good manufacturability has higher economic serviceability.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is according to the disintegrating machine that the utility model proposes U-lag build-up wear-resistant hammehead structure schematic diagram.
The specific embodiment
Among the figure: 1, surface overlaying layer, 2, the U-lag overlay cladding, 3, the tup body, I, tup abrading section.
I district, abrading section processes U-lag at tup 3 top, then with the layering filling built-up welding successively of high-wear-resistant alloy flux-cored wire from the bottom, reach desired shape (making the shape before the tup top reaches out U-lag), form U-lag overlay cladding 2, use high-wear-resistant alloy flux-cored wire build-up wear-resistant layer again on tup abrading section I surface, form surface overlaying layer 1.Hardness 〉=HRC55 after the built-up welding.Tup body 3 has good comprehensive mechanical performance for structural alloy steel forges after the modulation treatment.
Claims (1)
1. a disintegrating machine is with U-lag build-up wear-resistant tup, comprise that tup body (3) and surface overlaying layer (1) constitute, it is characterized in that: the district has U-lag in abrading section, tup top (I), in U-lag, there is layering to fill the high-wear-resistant alloy overlay cladding of built-up welding, form U-lag overlay cladding (2), on surface, tup abrading section (I) district high-wear-resistant alloy build-up wear-resistant floor is arranged, form surface overlaying layer (1).
