Abstract
The invention provides a hammer head knife edge strengthening process of an impact crusher. The process comprises the following steps of: firstly heating the surface of a hammer head knife edge part to a melting point of a body material, then spraying chromium carbide (Cr3C2) powder on the surface, heating the sprayed CrC2 powder to 1900 DEG C, enabling the Cr3C2 powder to be smelted, enabling the smelted Cr3C2 to be fused with the hammer head knife edge body material, spraying the Cr3C2 powder on the surface, heating the sprayed Cr3C2 powder to 1900 DEG C, enabling the smelted Cr3C2 to be fused with the hammer head knife edge body material, and finally cooling to the room temperature. According to the hammer head knife edge strengthening process of the impact crusher, the Cr3C2 is spray welded on the hammer head knife edge of the impact crusher, the spray welding of the Cr3C2 can be implemented on the hammer head knife edge of the impact crusher which is made of different materials such as carbon steel, alloy steel and stainless steel, the process is simple, the cost is low, the strength and rigidness of the hammer head knife edge can be remarkably improved, high corrosion resistance can be achieved, and the service life can be tripled compared with that of a high manganese steel hammer head knife edge.
Description
Technical field
The present invention relates to a kind of impact breaker tup edge of a knife reinforcing process, divide the monolateral edge of a knife reinforcing process of tup and the bilateral edge of a knife reinforcing process of tup.
Background technology
Impact breaker will need broken article hammering to counterpunch board by the tup of high speed rotating, and article are smashed between tup and counterpunch board.Impact breaker production efficiency height is widely applied to every field.But, because the grinder hammerhead impact of bearing and wearing and tearing are quite big, so the edge of a knife of grinder hammerhead quick-wearing causes tup short work-ing life very much, influence ordinary production.Also useful Wimet adds and is welded in tup edge of a knife position, but comes off easily.When the needs fragmentation is corrosive article, the available stainless steel of hammer body part, the tup part is not wear-resisting with stainless steel, and it is not corrosion-resistant to add other material of weldering, same work-ing life is short.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides the impact breaker tup edge of a knife reinforcing process that a kind of technology is simple, cost is low, the tup edge of a knife that this explained hereafter is come out has high impact-resistance, high-wearing feature and highly corrosion resistant ability.
The technical solution used in the present invention is: a kind of impact breaker tup edge of a knife reinforcing process may further comprise the steps:
1) tup blade portion site surface is heated to the bulk material fusing point, then at surface spray Cr3C2 powder;
2) the Cr3C2 powder of spraying is heated to 1900 ℃, make the fusing of Cr3C2 powder, fuse with tup edge of a knife bulk material;
3) again at tup edge of a knife surface spray Cr3C2 powder, the Cr3C2 powder of spraying heated to 1900 ℃ fuses itself and tup edge of a knife bulk material;
4) the tup edge of a knife is cooled to normal temperature.
The Cr3C2 thickness of surfacing is 0.5mm ~ 1mm.
Beneficial effect of the present invention is: the present invention is with grinder hammerhead edge of a knife surfacing Cr3C2(chromium carbide), surfacing Cr3C2 can implement at the grinder hammerhead edge of a knife of unlike materials such as carbon steel, steel alloy, stainless steel, its technology is simple, cost is low, and tup edge of a knife intensity and hardness that the present invention makes improve significantly, and very high corrosion resistance nature arranged, compare with high mangaenese steel work-ing life, improved 3 times of life-spans.
Description of drawings
Fig. 1 is the structural representation of monolateral edge of a knife tup.
Fig. 2 is the structural representation of bilateral edge of a knife tup.
Embodiment
Fig. 1 of Figure of description is monolateral edge of a knife tup, and Fig. 2 is bilateral edge of a knife tup, and 1 among the figure is the Cr3C2 alloy of tup edge of a knife position built-up welding, and 2 is the tup body, and 3 is the hammer pin axis hole.
The invention provides a kind of impact breaker tup edge of a knife reinforcing process, this technology is with grinder hammerhead edge of a knife surfacing Cr3C2(chromium carbide), surfacing Cr3C2 can be at carbon steel, steel alloy, implement on the grinder hammerhead edge of a knife of unlike materials such as stainless steel, implementing process is as follows: at first tup blade portion site surface is heated to the bulk material fusing point, then at surface spray Cr3C2 powder, again the Cr3C2 powder of spraying is heated to 1900 ℃, make the fusing of Cr3C2 powder, fuse with tup edge of a knife bulk material, repeat above-mentioned steps again, at surface spray Cr3C2 powder, again the Cr3C2 powder of spraying is heated to 1900 ℃ and make its fusion, be cooled to normal temperature at last, the about 0.5mm ~ 1mm of Cr3C2 thickness of surfacing.
Built-up welding tup edge of a knife intensity and the hardness of Cr3C2 improve significantly, and very high corrosion resistance nature is arranged, improved impact resistance and high-wear resistance and the corrosion resistance of tup, compare with high mangaenese steel work-ing life, improved 3 times of life-spans.The tup edge of a knife reinforcing process that the present invention relates to adapts to the reinforcement that is used for any impact breaker tup edge of a knife.Especially for the fragmentation of the article that are corrosive, more can embody superiority of the present invention.
Claims (2)
1. impact breaker tup edge of a knife reinforcing process may further comprise the steps:
1) tup blade portion site surface is heated to the bulk material fusing point, then at surface spray Cr3C2 powder;
2) the Cr3C2 powder of spraying is heated to 1900 ℃, make the fusing of Cr3C2 powder, fuse with tup edge of a knife bulk material;
3) again at tup edge of a knife surface spray Cr3C2 powder, the Cr3C2 powder of spraying heated to 1900 ℃ fuses itself and tup edge of a knife bulk material;
4) the tup edge of a knife is cooled to normal temperature.
2. impact breaker tup edge of a knife reinforcing process as claimed in claim 1, it is characterized in that: the Cr3C2 thickness of surfacing is 0.5mm ~ 1mm.
