Abstract
The utility model discloses a thin-walled diamond drill bit, which is applied to the drilling and coring of reinforced concrete. The thin-walled diamond drill bit comprises a tool bit, a steel body and a drill rod, wherein the tool bit and the steel body are integrated, and the steel body is welded with the drill rod. The tool bit and the steel body are integrally formed through hot pressing, so that the strength of the drill bit is greatly improved, and the falling possibility of teeth and the tool bit is reduced.
Description
Technical field
The utility model relates to a kind of thin faced bit, be applied to steel concrete boring, get core.
Background technology
Thin drilling bit is meant thick 0.8～2.5 ㎜ of steel body wall, and cutter head work tooth wall thickness is the drill bit of 2.0 ㎜～5.0 ㎜.At present, the cutter head of thin faced bit and steel body are that split is welded, after cutter head is mixed by diamond particles and metal dust during making, through the hot-pressing sintering technique moulding.The tooth phenomenon very easily appears in the thin faced bit use of this structure turning around, falling from the commissure.
The utility model content
The technical problems to be solved in the utility model provides a kind of thin faced bit, and its cutter head and the steel body structure that is formed in one can improve the intensity of thin faced bit like this.
For solving the problems of the technologies described above, technical solution adopted in the utility model is a kind of thin faced bit, and it comprises cutter head, steel body and drilling rod, and its key technology is: described cutter head and steel body are structure as a whole.
Above-mentioned cutter head and steel body are structure as a whole through hot pressing is integral sintered; Above-mentioned steel body and drilling rod welding.
Adopt the beneficial effect that technique scheme produced to be: cutter head of the present utility model and steel body are structure as a whole, and intensity improves, and when the steel body welds with drilling rod away from cutter head, avoid diamond segment to influence its quality because of reheat.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Wherein, 1, drilling rod; 2, cutter head; 3, steel body.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Referring to accompanying drawing 1, the utility model comprises cutter head 2, steel body 3 and drilling rod 1, described cutter head 2 and steel body 3 structure that is formed in one, described steel body 3 and drilling rod 1 welding.Above-mentioned cutter head 2 and steel body 3 are structure as a whole through hot pressing is integral sintered.
The technological process of production of this novel thin faced bit is: and batch mixing-single cutter head automatically suppresses-and packing mould-bell jar stove hot pressing is integral sintered-Vehicle Processing-weld-polish-put the first edge on a knife or a pair of scissors-spray paint-put in storage.
In above-mentioned technological process, single cutter head 2 adopts full automatic press from dynamic pressure system, and efficient is than higher, the technology of whole compacting or not or adopted at present general cutter head, needs manual operation, and efficient is lower, it only is about 500 that class produces, and the current technology personnel are few, and it is about 3000 that class produces.
At the packing die process, cutter head 2 is put into respectively in the fixing mold cavity with steel body 3, and dress is imitated rate and increased substantially, the overcoat of mould adopts high purity graphite not yielding, inner core adopts stainless steel products, can well guarantee dimensional accuracy, and the structure of mould adopts prior art constructions to get final product.
The integral sintered quality that can significantly improve this thin faced bit of bell jar stove hot pressing, it is one that this kind technology makes cutter head 2 and steel body 3 alloying cementing under high-temperature liquid state, in use be difficult for turning around, falling tooth, and the cutter head 2 of original thin faced bit and steel body 3 are welded for split, are prone in the use and turn around, fall the tooth phenomenon from the commissure.
Welding sequence adopts the low-temperature protection welding, and steel body and drilling rod split welding, cutter head 2 be away from welding the high-temperature region, and avoid the diamond reheat and influence its product quality, thus the more effective product quality that guaranteed.When cutter head 2 wearing and tearing can not be used, also can recycle, the welding cutter head is reused on the steel body.
Claims (2)
1. thin faced bit, it comprises cutter head (2), steel body (3) and drilling rod (1), it is characterized in that: described cutter head (2) and steel body (3) are structure as a whole.
2. diamond thin-wall drill bit according to claim 1 is characterized in that: described cutter head (2) and steel body (3) are through the hot pressed sintering structure that is formed in one.
