Abstract
The utility model provides a dry-type coring bit. The dry-type coring bit comprises a core pipe (1) and cutter heads (2) fixedly connected at ends of the core pipe. A plurality of chip removal grooves (3) which concave inwards in a radial direction of the core pipe are symmetrically distributed on the outer walls of the chip removal grooves (3). Impact of force can be well overcome by fully utilizing the chip removal grooves symmetrically distributed on the outer walls of the core pipe (3), and dual functions of chip removing and cooling are achieved. The dry-type coring bit further has the advantages that use is convenient and fast, water spots are not generated in the using process, and cleaning labor capacity is not increased.
Description
Technical field
The utility model relates to coring bit, particularly a kind of dry type coring bit.
Background technology
Coring bit is hollow boring bit again, present existing coring bit is submersible, can be seriously polluted to wall and surface in the process of using, after bore operation finishes, water stain cleaning to wall and surface is pretty troublesome, especially in electrical type factory antistatic floor is installed all, band water perforate meeting damages floor and electronic product, and water stain being difficult to of causing with water cooling in boring procedure clears up.
Summary of the invention
The purpose of this utility model is: provide a kind of convenient to use and in use do not have water stainly, can not increase the cleaning amount of labour.
The utility model dry type coring bit comprises the core pipe and is fixed in the cutter head of core tube end, be symmetrically distributed with on the pipe outer wall of described core pipe several along the core caliber to recessed chip area.
As further improvement of the utility model, described chip area has 4.
As further improvement of the utility model, described chip area is fork-shaped.
In sum, the beneficial effects of the utility model are: adopt pipe outer wall at the core pipe be symmetrically distributed with several along the core caliber to recessed chip area, take full advantage of the impact that the chip area on the pipe outer wall that is symmetrically distributed in the core pipe can solve power well, realized chip removal and cooling dual-use function; And the wind that circles round that adopts the fork-shaped chip area in use to produce cools off, and reduces impulsive force and has made things convenient for chip removal.
Description of drawings
Fig. 1 is schematic diagram of the present utility model;
Among the figure: 1 core pipe, 2 cutter heads, 3 chip areas.
The specific embodiment
The present invention will be further described below in conjunction with the specific embodiment:
As shown in Figure 1, present embodiment comprises: core pipe 1 and be fixed in the cutter head 2 of core tube end, be symmetrically distributed with on the pipe outer wall of described core pipe 3 several along the core caliber to recessed chip area 3.Chip area 3 has 4 in the present embodiment; And described chip area 3 is fork-shaped.
With employing dry type coring bit concrete being carried out bore operation is example, the chip that utilizes chip area to bore to remove is discharged, utilize the chip area of drill bit simultaneously under the high speed rotation status, the wind that circles round that produces cools off diamond segment rapidly, make concrete produce strain, produce the stretching crack this moment, form shear crack and spliced body then, diamond slides along the rock stratum of previous diamond fragmentation, the cutting residue that produces is discharged from chip area, and the concrete that last drill bit becomes soft because the tensile stress effect makes carries out boring and coring.
Claims (3)
1. dry type coring bit comprises core pipe (1) and is fixed in the cutter head (2) of core tube end, it is characterized in that being symmetrically distributed with on the pipe outer wall of described core pipe (3) several along the core caliber to recessed chip area (3).
2. dry type coring bit according to claim 1 is characterized in that described chip area (3) has 4.
3. dry type coring bit according to claim 1 is characterized in that described chip area (3) is fork-shaped.
