Abstract
The utility model relates to a composite abrasion-resistant surfacing hammerhead which is industrially used for crushing materials. The hammerhead comprises a basal hammerhead body and an abrasion-resistant alloy layer; the top and the periphery of the basal hammerhead body are wrapped by the abrasion-resistant alloy layer; and the basal hammerhead body is connected with the abrasion-resistant alloy layer by a welding method. The welding method can be the surfacing method. The surface of the part of the top of the basal hammerhead body, which is connected with the abrasion-resistant alloy layer, can be provided with a surfacing recess, in which the lower part of the abrasion-resistant alloy layer is embedded. The abrasion-resistant alloy layer can wrap both the top and the periphery of the basal hammerhead body. The material of the basal hammerhead body can be ordinary cast steel or forged steel. The hammerhead has the advantages of simple structure, high abrasion resistance, high toughness, long service life and the like, and cannot be easily broken or chipped when in use.
Description
Technical field
The utility model relates to a kind of industrial complex abrasion-proof built-up welding tup that is used for broken raw material.
Background technology
Needs such as sintering plant, coke-oven plant are pulverized the means of raw material all by key tool in " reversible pair of counter beating hammer type disintegrator "-tup realization at present.The tup of this disintegrating machine tup in the catalase process can run into such as hard thing such as iron block, admant, under HI high impact, can make tup phenomenons such as piece, fragmentation, strong wearing and tearing occur falling, not only influence disintegrating machine and pulverize the work quality and the progress of raw material, the dynamic balancing that also causes disintegrating machine simultaneously is unbalance and termination work.A common tup only has the service life of two wheat harvesting periods.Intensity and the frequency of maintenance, replacing have been increased the weight of greatly; Increase the cost of coal, sintering, coking greatly, become a big difficult point of coal in the production process, sintering, coking work.
The utility model content
In order to solve the aforementioned problems in the prior, the utility model provides a kind of simple in structure, wearability and good toughness, is difficult for composite wear-resistant hammerhead broken, that life cycle is long.The utility model is achieved in that
Complex abrasion-proof built-up welding tup is characterized in that it comprises tup matrix and wear-resistant alloy layer; Wear-resistant alloy layer be coated on tup matrix top and around; The tup matrix is connected by welding manner with wear-resistant alloy layer.
Described welding manner can be the built-up welding mode.
The adjacent part surface of described tup matrix top and wear-resistant alloy layer can be provided with the built-up welding groove, and the underclad portion of wear-resistant alloy layer embeds among the built-up welding groove.
Described wear-resistant alloy layer can be coated on tup matrix top and all around simultaneously.
Described tup matrix material can be normal steel casting, forged steel.
The technical thought of the utility model development is so that the tup working condition is carried out when raw materials such as lime stone, dolomite carry out fragmentation to " reversible pair of counter beating hammer type disintegrator " in the process of coal, sintering, coking.And to the tup working condition carried out detailed observation, research, analysis and short at tup cracky, the life-span of former use, fall helpless defective such as piece, with practicality and applicability take development and Design as the leading factor " composite wear-resistant hammerhead " this new product solved " reversible pair of counter beating hammer type disintegrator " and carrying out fragmentation, phenomenons such as piece, fragmentation, strong wearing and tearing appear falling in the tup of disintegrating machine under HI high impact.Specifying of its major technique feature is as follows:
(1). hammer head material: two kinds of a kind of high manganese cast steels that are employing Mn13 as matrix of material are arranged in the former tup tradition.Mn13 impacts the lower body surface through the tough processing of water back at top load can produce martensitic structure, thereby plays wear-resisting effect, but in actual applications, does not all reach so big shock loading usually, makes tup not reach the service life of expection.Second kind is composite high-chromium iron-cast, this material is that wear-resisting in the hope of reaching tup, hammer handle has impact strength with No. 45 cast steel and rich chromium cast iron composite casting together, but piece, broken phenomenon can appear falling in tup under HI high impact in shattering process, cause that the disintegrating machine dynamic balancing is unbalance.
Matrix material of the present utility model is elected normal steel casting, the forged steel with certain impact flexibility as, so that carry out high-tech Surface Treatment Engineering-compound a kind of wear-resisting, impact-resistant alloy on the tup surface.
(2). built-up welding groove structure: on matrix of the present utility model, make some built-up welding grooves.Purpose is for reinforced surface composite wear-resisting alloy and high base strength, reach existing high wearability good toughness is arranged again, make the utility model be implemented in the shattering process tup and under HI high impact, avoid occurring falling piece, broken phenomenon, improve the service life of tup, prolong tup and change frequency, alleviate repair density.
(3). the built-up welding form.Composite wear-resisting alloy is realized with combining by the built-up welding welding of matrix.Its Type of Welding: at first the built-up welding groove being filled expires, and reaches the top then and carry out built-up welding around tup, covers the matrix of tup working position fully.
During structure of the present utility model and advantage see the following form with prior art in tup contrast:
More than contrast the utlity model has simple in structure, wearability and is difficult for fragmentation or falls advantages such as piece, long service life with good impact resistance, in using as can be seen.
The utility model is described in further detail to engage drawings and the embodiments below.
Description of drawings
Fig. 1 is the A-A generalized section of the utility model structural representation Fig. 2 for Fig. 1
The specific embodiment
Referring to accompanying drawing 1, Fig. 2, a kind of composite wear-resistant hammerhead, it comprises tup matrix 1 and wear-resistant alloy layer 3; Wear-resistant alloy layer is coated on tup matrix top and all around simultaneously; The tup matrix is connected by the built-up welding welding manner with wear-resistant alloy layer.The adjacent part surface of described tup matrix top and wear-resistant alloy layer also is provided with built-up welding groove 2, and the underclad portion of wear-resistant alloy layer embeds among the built-up welding groove.Described tup matrix material can be normal steel casting, forged steel.The utlity model has simple in structure, wearability and good impact resistance, be difficult for broken in using or fall advantages such as piece, long service life.
