Abstract

The invention discloses a kind of thin faced bit, be applied to the boring of armored concrete, coring, it includes that cutter head, steel body and drilling rod, cutter head and steel body use integrative-structure, and steel body welds with drilling rod.The cutter head of the present invention and steel body use hot pressed sintering one-body molded, and the intensity of drill bit is greatly improved, and are difficult to occur tooth, turn around phenomenon.

Description

Thin faced bit
Technical field
The present invention relates to a kind of thin faced bit, be applied to the boring of armored concrete, coring.
Background technology
Thin drilling bit refers to that steel body wall thick 0.8~2.5, cutter head work tooth wall thickness are the brill of 2.0~5.0 Head.At present, the cutter head of thin faced bit and steel body are that split is welded, and during making, cutter head is by diamond particles and metal After powder mix homogeneously, through hot-pressing sintering technique molding.The thin faced bit of this structure easily occurs during using Turn around from commissure, fall tooth phenomenon.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of thin faced bit, and its cutter head is formed in one with steel body Structure, so can improve the intensity of thin faced bit.
For solving above-mentioned technical problem, the technical solution used in the present invention is a kind of thin faced bit, and it includes Cutter head, steel body and drilling rod, 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 welds with drilling rod.
Use and have the beneficial effects that produced by technique scheme: cutter head and the steel body of the present invention are structure as a whole, by force Degree improves, and when steel body welds with drilling rod away from cutter head, it is to avoid diamond segment affects its quality because of post bake.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention;
Wherein, 1, drilling rod;2, cutter head;3, steel body.
Detailed description of the invention
The present invention is further detailed explanation with detailed description of the invention below in conjunction with the accompanying drawings.
Seeing accompanying drawing 1, the present invention includes that cutter head 2, steel body 3 and drilling rod 1, described cutter head 2 are integrated into steel body 3 Type structure, described steel body 3 welds with drilling rod 1.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 thin faced bit of the present invention is: batch mixing-single cutter head automatically suppresses-subpackage Mould-clock hood type furnace hot pressing is integral sintered-and 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 uses full automatic press from dynamic pressure system, and efficiency comparison is high, and current one As cutter head do not suppress or use the technique of overall compacting, need manual operation, efficiency comparison is low, and class produces and is only about 500, and Current technology personnel are few, and it is about 3000 that class produces.
At subpackage die process, cutter head 2 and steel body 3 are put in fixing mold cavity respectively, and die-filling efficiency significantly carries Height, the overcoat of mould uses high purity graphite to be unlikely to deform, and inner core uses stainless steel products, can well ensure dimensional accuracy, mould The structure of tool uses the structure of prior art.
The integral sintered quality that can significantly improve this thin faced bit of clock hood type furnace hot pressing, this kind of technique makes cutter head 2 are integrated with steel body 3 alloying cementing under high-temperature liquid state, and be in use difficult to turn around, fall tooth, and original thin-walled Cutter head 2 and the steel body 3 of diamond bit are welded for split, easily occur turning around from commissure, falling tooth now during use As.
Welding sequence uses low-temperature protection welding, and steel body welds with drilling rod split, and cutter head 2 is away from welding high-temperature region, it is to avoid Diamond post bake and affect its product quality, thus more effectively ensure that product quality.When cutter head 2 abrasion can not make Used time, also may be recovered utilization, steel body welds cutter head and reuses.
