Abstract
The utility model relates to a diamond with thin wall engineering dry driller, which is composed of a diamond tool bit (1), a drill rod (2) and a connection thread (6). The utility model is characterized in that not less than one first U-shaped notch (3) is arranged on the end surface (7) of the diamond tool bit, and a corresponding and staggered second U-shaped notch (4) is also arranged at the lower part of the corresponding diamond tool bit (1). By adopting the structure of the utility model, the dropout problem of the diamond in the tool drilling process is solved, thus the diamond has better edge protruding height and speed in the drilling process, therefore the tool in the continuous high-speed drilling work state is ensured, and the drilling efficiency is improved multiply. Through a hole drilling test, in the anhydrous source area, the speed of the dry drilling is 12000 revolution per minute, the hole drilling time is between 8 and 10 seconds for 2 centimeter granite flagstone material, and continuous hole drilling can be performed for 30 times.
Description
Technical field
The utility model relates to the instrument that is used to hole in the high speed engineering, especially about laser weld high speed thin diamond wall engineering drilled dry.
Technical background
Technology of Diamond Thin-Wall Drilling Bit is a kind of novel boring bar tool, is made up of round steel tube and cutter head, has that bore size is accurate, speed is fast, the material periphery is not had damage and do not need characteristics such as subsequent handling.Be mainly used in and in various construction materials, creep into aperture and major diameter eyelet, during especially for engineering renovation or building reconstruction the laying of electric wire or pipeline favourable, this external concrete is deep, its instrument that also is absolutely necessary when cutting large diameter hole.Yet the Technology of Diamond Thin-Wall Drilling Bit that adopts traditional handicraft to make, in traditional manufacturing technique, wet brill (adding water-cooled) has certain limitation, under the drilled dry condition, heat that produces during the high speed rotary work and great shear forces and easily cause drill bit diamond drop-off, diamond to polish, phenomenon such as drill bit bursts apart, cutter head comes off, the influence of environment can't be fully played it, and no water source is wet main weak point of boring.
Summary of the invention
In order to overcome above deficiency; it is a kind of in laser weld high speed thin diamond wall engineering the drilling that the purpose of this utility model is to provide, and the technology of diamond segment and the making of shape have the fully effectively adamantine thin diamond wall engineering drilled dry that goes out to consider to be worth doing performance of protection of unique protection radiating effect, carcass.
The technical solution of the utility model realizes in the following manner: thin diamond wall engineering drilled dry, form by diamond segment, drilling rod and connecting thread, it is characterized in that: the end face of described diamond segment has the U type notch one that is no less than, and corresponding bottom also has U type notch two corresponding and dislocation.
Above-mentioned diamond segment and drilling rod be connected to laser weld.
It is along the radially equally distributed groove of diamond segment that above-mentioned U type notch one and U type notch two are.
Also have chip area on the above-mentioned drilling rod.
Above-mentioned chip area and drilling rod radially become 10-45 ° of angle.
Above-mentioned diamond segment, drilling rod are thin-walled.
Adopt the utility model structure, solved the diamond drop-off problem in the instrument drilling process, make diamond that height of protrusion and speed preferably be arranged in drilling process, thereby make the continuous high speed of instrument creep into duty, drilling efficiency significantly improves.Through borehole test, at no watershed drilled dry, speed: 12000 rev/mins, 2 centimeters granite slate material, drilling time, can be holed 30 times between second continuously at 8-10.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a left view of the present utility model.
The specific embodiment
Know by Fig. 1, thin diamond wall engineering drilled dry in the present embodiment, form by diamond segment 1, drilling rod 2 and connecting thread 6, have 3 evenly distributed U type notches 1 on the end face 7 of described diamond segment 1 along its garden Zhou Fangxiang, corresponding bottom also has U type notch 24 corresponding and dislocation, diamond segment 1 adopts laser weld with being connected of drilling rod 2, also has chip area 5 on the drilling rod 2, and chip removal is used during for diamond segment 1 work.Its shape radially becomes one 30 ° of angles with drilling rod, has unique self-shield radiating effect, has protected the adamantine sword performance that goes out fully effectively.
Being known by Fig. 2, is the left view of present embodiment, and diamond segment 1 and drilling rod 2 are thin-walled garden ring, and interior is the hole thimble, and the stress point of diamond segment 1 is at the end face 7 of cutter head, and it is in order to dispel the heat and to be convenient to chip removal that end face 7 is provided with U type notch 1.
The utility model adopts international advanced laser welding technology, make sintered body diamond segment 1 and drilling rod 2 have higher welding fastness, not only improved the service life of workpiece, and drilling efficiency and security in the workpiece course of work have been strengthened, while is owing to laser weld precision height, weld seam are narrow, can also effectively reduce the noise pollution in the workpiece course of work, in addition, used scolders such as the high-frequency welding of traditional handicraft mostly are Gao Yin or other precious metal material, and laser welding technology does not need to use special-purpose scolder.
The utility model is by using above-mentioned technology, effectively solved the Technology of Diamond Thin-Wall Drilling Bit that adopts traditional handicraft to make, under the drilled dry condition, heat that produces during the high speed rotary work and great shear forces and easily cause drill bit diamond drop-off, diamond to polish, phenomenon such as drill bit bursts apart, cutter head comes off, make workpiece reach the serviceability requirement that the drilled dry under the superelevation drilling speed situation creeps into fully, drilling efficiency significantly improves than the drill bit that adopts traditional handicraft to produce.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
