Abstract
The invention discloses a kind of imbedding process of composite hammer head, the following steps are included: a, selection material: manufacturing tup using the compound method of rich chromium cast iron-carbon steel, wherein tup uses rich chromium cast iron, and hammer handle uses ZG270-550, and oil removing cleaning, then Dehydroepiandrosterone derivative are carried out to raw material；B, Selection Model；C, moulding；D, compound: entire sand mold being put into Medium frequency induction coil before compound, hammer handle is preheated by Medium frequency induction, starts casting of molten metal when reaching certain temperature；E, be heat-treated: carrying out annealing and tempering after the completion of castingin, f, measurement are examined: the qualified storage that is packaged is examined in measurement, and measurement tolerance is no more than 0.7-1.5cm.The present invention is under identical working condition, and the composite hammer head produced with insert process, the service life is potassium steel more than 2 times, and simple production process, at low cost, and the frequency of tup replacement is reduced after the tup produced using the technique, has saved production cost, convenient for promoting.
Description
Technical field
The present invention relates to mining equiment manufacture field, the imbedding process of specifically a kind of composite hammer head.
Background technique
Crusher is the widely used crushing mechanism of the industries such as cement, ceramics, mine and electric power, and tup is that its is main easily
Wear-out part mostly uses potassium steel to manufacture for a long time；In the research and application of grinder hammerhead, although having been achieved for larger
Progress, but tup is still that the service life is most short, one of the maximum component of consumption, and it is to solve the problems, such as having for this that bimetallic is compound
Effect approach；Tup is whole can be divided into hammer handle and hammer tip two parts according to job specification difference, and different parts require not
Same service performance, hammer handle require comprehensive mechanical performance, to there is certain intensity and toughness；And the main portion of tup abrasion
Position is hammer tip portion, therefore it is required that hammer tip wear-resisting property with higher, could extend the tup service life；Not for the tup analyzed
The case where requiring different service performances with position, the present invention mention the imbedding process for being total to a kind of composite hammer head.
Summary of the invention
The purpose of the present invention is to provide a kind of imbedding process of composite hammer head, mentioned above in the background art to solve
Problem.
To achieve the above object, the invention provides the following technical scheme:
A kind of imbedding process of composite hammer head, comprising the following steps:
A, it chooses material: tup is manufactured using the compound method of rich chromium cast iron-carbon steel, wherein tup uses rich chromium cast iron,
Hammer handle uses ZG270-550, and carries out oil removing cleaning to raw material, then Dehydroepiandrosterone derivative；
B, Selection Model: hammer tip, well and ingate use lost pattern, and riser, riser neck and sprue are using wood
Mould model；
C, moulding: need to remove the hammer handle compound position surface irregularities that pre-production goes out, while coated guarantor when moulding again
Agent is protected, hammer tip evaporative pattern is put on, is put into the direct moulding of sand mold；
D, compound: entire sand mold is put into Medium frequency induction coil before compound, hammer handle is preheated by Medium frequency induction,
Start casting of molten metal when reaching certain temperature；
E, it is heat-treated: carrying out annealing and tempering after the completion of castingin, specifically tup is integrally heated slowly to
700-960 DEG C, keep the temperature 4-10h, air blast cooling of coming out of the stove quenching；When casting temperature is lower than 100 DEG C, enters furnace again and carry out at tempering
Reason, tempering temperature are 300-400 DEG C, keep the temperature 3-6h, come out of the stove air-cooled；
F, measurement is examined: the qualified storage that is packaged is examined in measurement, and measurement tolerance is no more than 0.7-1.5cm.
Further, its pouring temperature is 1300-1600 DEG C in the step (d).
Compared with prior art, it the beneficial effects of the present invention are: under identical working condition, is produced with insert process compound
Tup, the service life is potassium steel more than 2 times, and simple production process, at low cost, is reduced after the tup produced using the technique
The frequency of tup replacement, has saved production cost, convenient for promoting.
Specific embodiment
Below in conjunction with the embodiment of the present invention, technical scheme in the embodiment of the invention is clearly and completely described,
Obviously, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based in the present invention
Embodiment, every other embodiment obtained by those of ordinary skill in the art without making creative efforts, all
Belong to the scope of protection of the invention.
A kind of imbedding process of composite hammer head, comprising the following steps:
A, it chooses material: tup is manufactured using the compound method of rich chromium cast iron-carbon steel, wherein tup uses rich chromium cast iron,
Hammer handle uses ZG270-550, and carries out oil removing cleaning to raw material, then Dehydroepiandrosterone derivative；
B, Selection Model: hammer tip, well and ingate use lost pattern, and riser, riser neck and sprue are using wood
Mould model；
C, moulding: need to remove the hammer handle compound position surface irregularities that pre-production goes out, while coated guarantor when moulding again
Agent is protected, hammer tip evaporative pattern is put on, is put into the direct moulding of sand mold；
D, compound: entire sand mold is put into Medium frequency induction coil before compound, hammer handle is preheated by Medium frequency induction,
Start casting of molten metal when reaching certain temperature；
E, it is heat-treated: carrying out annealing and tempering after the completion of castingin, specifically tup is integrally heated slowly to
700-960 DEG C, keep the temperature 4-10h, air blast cooling of coming out of the stove quenching；When casting temperature is lower than 100 DEG C, enters furnace again and carry out at tempering
