Abstract
The invention discloses a bi-metal hammer head and a casting process thereof. The hammer head comprises a hammer head body and a hammer handle connected with the former, wherein a wear-resistant area is arranged at the joint of the hammer handle and the hammer head body and is extended, in a downward oblique cutting manner, from the hammer head body to the root part of the hammer handle. The casting process comprises the following steps: first, low alloy steel or common cast steel is filled in a sprue of the hammer handle to cast a hammer handle; and then, when the steel liquid in the hammer handle is near the composite interface of the hammer handle and the hammer head body, filling high-chromium iron or high alloy steel into a sprue of a hammer head body after 3-20s, so as to cast a hammer head body. According to the invention, a double-liquid bi-metal composite casting method is adopted to produce a hammer type hammer head, the working surface has very high wear resistance, the hammer handle part of a traditional hammer head is more resistant to wear; and meanwhile, the hammer handle part has favorable impact ductility, so that the characteristics of all materials are fully utilized, thereby prolonging the service life of the hammer head.
Description
Technical field
The present invention relates to disintegrating machine processing and manufacturing field.What be specifically related to is a kind of bimetallic tup and casting technique thereof.
Background technology
Hammer type hammerhead is the strength member on the disintegrating machine, also be to consume maximum, the part of easy damage on the disintegrating machine, consumption is very big, mainly be because the hammer handle of tup and the residing working condition of hammer tip different, require the material of hammer handle to have certain intensity and toughness, and tup is the position of main wearing and tearing, requires the material of tup to have higher wearability, but also can form certain impact to hammer handle owing to broken material in the use of reality.Referring to Fig. 1, under acting on repeatedly for a long time, especially large stretch of wearing and tearing can appear in the hammer handle near the hammer tip part.
Summary of the invention
The object of the invention provides a kind of bimetallic tup and casting technique thereof, and it can solve existing problem in the background technology effectively.
A kind of bimetallic tup, it comprises tup and is attached thereto hammer handle, and the junction between described hammer handle and the tup is provided with wear-resisting district, and this wear-resisting district is made of the root that the downward oblique cutting of tup extends to hammer handle.
Described tup selects for use a kind of casting in rich chromium cast iron or the high-alloy steel to form.
Described hammer handle selects for use a kind of casting in low-alloy steel or the normal steel casting to form.
A kind of casting technique of biliquid metal composite tup, a kind of the watering of injecting low-alloy steel or normal steel casting earlier in the hammer handle sprue gate casts out hammer handle, when the molten steel in the hammer handle arrives near the compound interface of hammer handle and tup, at interval 3-120 second, a kind of the watering of injecting rich chromium cast iron or high-alloy steel again in the tup sprue gate casts out tup.
The junction of described hammer handle and tup is provided with puts chill material.
The described chill material of putting is the higher metal material of heat dispersion.
Owing to adopted above technical scheme, the present invention has following beneficial effect: owing to adopt the double-fluid double metal composite casting method to produce hammer type hammerhead, make working face have very high wearability, make the hammer handle position of original tup have more wearability, hammer handle portion has good impact flexibility simultaneously, given full play to the speciality of various materials, is improved the service life of tup.
Description of drawings
In order to be illustrated more clearly in the present invention, below in conjunction with accompanying drawing embodiment is done simple introduction.
Fig. 1 is the schematic diagram of background technology among the present invention;
Fig. 2 is structural representation of the present invention;
Fig. 3 is cast schematic diagram of the present invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described.
Referring to Fig. 2, this specific embodiment is to be achieved by the following technical solutions, it comprises tup 1 and is attached thereto hammer handle 2, junction between described hammer handle 2 and the tup 1 is provided with wear-resisting district 3, this wear-resisting district 3 is made of the root that tup 1 downward oblique cutting extends to hammer handle 2, because wear-resisting district 3 adopts with the casting of tup 1 identical materials and forms, make it when having guaranteed that hammer handle 2 has higher intensity and toughness, can increase its whole wearability again, increase its whole service life greatly.
Described tup 1 selects for use a kind of casting in rich chromium cast iron or the high-alloy steel to form.
Described hammer handle 2 selects for use a kind of casting in low-alloy steel or the normal steel casting to form.
Referring to Fig. 3, a kind of casting technique of biliquid metal composite tup, a kind of the watering of injecting low-alloy steel or normal steel casting earlier in hammer handle sprue gate 4 casts out hammer handle 2, when the molten steel in the hammer handle 2 arrives near the compound interface of hammer handle 2 and tup 1, at interval 3-120 second, a kind of the watering of injecting rich chromium cast iron or high-alloy steel again in tup sprue gate 5 casts out tup 1.
For the crystalizing interface that guarantees tup 1 and hammer handle 2 and matrix have certain thermograde and certain thickness and complete combination interface, the junction of described hammer handle 2 and tup 1 is provided with puts chill material 6.
The described chill material 6 of putting is the higher metal material of heat dispersion.
Owing to adopted above technical scheme, the present invention has following beneficial effect: owing to adopt the double-fluid double metal composite casting method to produce hammer type hammerhead, make working face have very high wearability, make the hammer handle position of original tup have more wearability, hammer handle portion has good impact flexibility simultaneously, given full play to the speciality of various materials, is improved the service life of tup.
