Abstract
The utility model discloses a double-blade PDC composite percussion drill, particularly relates to a double-blade PDC composite percussion drill manufactured by compounding of diamond and a hard alloy layer. The double-blade PDC composite percussion drill aims to solve the technical problems that the conventional used drill bit is poor in abrasive resistance, impact resistance and heat-conducting property, and short in service life, and comprises a drill rod and a drill bit clamped in the drill rod, wherein the drill bit comprises an interlayer and outer layers pressed and connected onto the two sides. The double-blade PDC composite percussion drill has the advantages that the efficient drilling can be ensured, and the abrasive-resistant drilling effect is realized at the same time; the service life of each blade is prolonged; the purposes that the cutting blades are shaper, the heat effect is lower, and the heat-conducting property of the cutter material is more excellent are realized; the drilling and cutting operation is quicker and more efficient, the more economical and practical effects are achieved, and the defects of drilling of the conventional drill bit are overcome.
Description
Technical field
The utility model relates to a kind of Churn drill, is specifically related to a kind of compound Churn drill of twolip PDC that adopts diamond, hard alloy layer to be composited.
Background technology
At present, to concrete floor, wall, fragment of brick, building stones, carry out the Churn drill of percussion drilling on composite plate and multilayer material, and on market, modal drill bit material is to weld carbide drill, coated drill etc. on drilling rod.When using this carbide drill punching, when running into than the dry concrete body of wall, the wearing and tearing of carbide drill are very serious.And, limited by Hardmetal materials, this drill bit wears no resistance, heat conductivility is bad, the life-span is short.
Can use a kind of drill bit when guaranteeing efficient drilling, realize wear-resistant, economical and practical drilling effect, this have just become to improve the key of drilling steel concrete efficiency.
Summary of the invention
The technical problems to be solved in the utility model is that the drill bit of current use wears no resistance, not shock-resistant, heat conductivility is bad, the life-span is short, provides a kind of and can improve drilling life of bit, the compound Churn drill of twolip PDC of shock-resistant, wear-resistant, good heat conductivity.
For achieving the above object, the utility model adopts following technical proposals: the compound Churn drill of a kind of twolip PDC, and comprise drilling rod and be clamped in the drill bit in drilling rod, described drill bit comprises the skin of intermediate layer and both sides crimping.
Described intermediate layer is diamond layer, and skin is hard alloy layer.
Described intermediate layer thickness is 0.5-2.0mm, and outer gross thickness is 1.0-8.0mm.
Described intermediate layer thickness is 1.2mm, and outer layer thickness is 5.0mm.
Adopt the utility model of said structure, can be when guaranteeing efficient drilling, realize anti abrasive drilling effect, improve blade life, realize more sharp-cutting edge, lower heat affecting, more excellent cutter material heat conductivility, make drilling more brisk more efficient, more economical practicality, make up the shortcoming that has drilling now.

Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the drill bit structure schematic diagram.
Fig. 4 is the B-B sectional view of Fig. 3.
Use state diagram when Fig. 5 is Churn drill drilling reinforced concrete wall.
The specific embodiment
As shown in Figures 1 to 4, the utility model comprise drilling rod 1 and with the drill bit 2 that is clamped in 1 li, drilling rod, described drill bit 2 comprises intermediate layer 3 and is compounded in the skin 4 of 3 both sides, intermediate layer.Drill bit 2 is welded in the rectangular channel of drilling rod 1.
Described intermediate layer 3 is diamond layer, and outer 4 is hard alloy layer.
Described intermediate layer 3 thickness are 0.5-2.0mm, and outer gross thickness is 1.0-8.0mm.
Described intermediate layer 3 thickness are 1.2mm, and outer 4 thickness are 5.0mm.Intermediate layer 3 thickness can be also 0.5 mm, 0.8 mm, 1.0 mm, 1.4 mm, 1.6 mm, 2.0mm, and outer 4 thickness can be also 1.0mm, 2.0 mm, 3.0 mm, 4.0 mm, 6.0 mm, 8.0mm.
The utlity model has superpower hardness, abrasion resistance, self-sharpening, and rub and examine the advantages such as coefficient is little; Intermediate layer 3 is diamond layer, and that diamond has is superhard, wear-resisting, Heat Conduction, semiconductor and the excellent physical property such as far away thoroughly, can carry out long-life efficient drilling, can adapt to severe working environment; Structural representation when Fig. 5 is Churn drill drilling reinforced concrete wall 5, through evidence, this drill bit drilling efficiency exceeds 20 times than the market common drill bit.
