Description
Technical field
The utility model relates to boring bar tool field, refers to a kind of split type diamond thin-wall drill bit matrix terminal pad and manufacture craft thereof especially.
Background technology
Adamantine consumption, the diamond amount that often processing 1,000,000 tons of iron and steel are used represents the Industry Development Level of this country, U.S., day and western countries' consumption all draw every 1,000,000 tons of steel at 18 ~ 20 myriagrams, the U.S. is the country that diamond consumption is maximum in the world, and China is then that 2.4 myriagrams draw every 1,000,000 tons of steel.
Along with industrial expansion, diamond abrasive article has all more and more been used in building and other field, wherein, engineering thin wall drilling bit is exactly wherein a kind of, also known as rhinestone head, hollow boring bit, be mainly used in building, when water, electricity, warm, coal gas, air-conditioning, Pipe installing, beat porthole, also have boring, the jacking of the foundation engineerings such as highway, airfield runway, bridge, tunnel, get core, and the nonmetal fragile material of answering such as stone material, pottery punches etc.Engineering thin wall drilling bit must be connected to matrix the normal operation just can guaranteeing equipment with brill in use, but the most integral type forging of the terminal pad of existing diamond thin-wall drill bit matrix forms, not only production efficiency is low, and due to the first difference of matrix dish, required mould is numerous, and production cost is very high.
Utility model content
The utility model proposes a kind of diamond thin-wall drill bit matrix terminal pad, solve the problem that above-mentioned background technology proposes.
A kind of diamond thin-wall drill bit matrix terminal pad, comprises disk body first with dish, is characterized in, disk body center is provided with through hole, and through hole is provided with internal thread, and dish is first is provided with corresponding external screw thread to disk body link, both are threaded connection, and the outer be threaded welding.
As further technical scheme, internal thread is M45 × 2 internal thread.
As further technical scheme, the chamfering outer that on disk body, the outboard end of through hole is provided with is highly 4.5mm, angle is 45 °.
As further technical scheme, the outside solder side of disk body and the vertical range of disk body lateral surface are 0.5mm; Inner side solder side outside disk body medial surface is connected with dish is first is inner concave, and radius is 3mm, arc length is 18.84mm.
As further technical scheme, the cross section of dish head is the one in equilateral triangle, square, regular pentagon, regular hexagon or octagon.
The utility model beneficial effect:
The utility model changes disk body and dish head into split type production, make standard disk body can independent assortment with dish head, no longer need one forging molding, not only production cost significantly reduces, and can produce in a large number in process of production and the disk body of operating level part, produce difform dish more according to demand first, finished product terminal pad can be obtained after combination, welding, substantially increase production efficiency.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the utility model cross-sectional view;
Fig. 2 is the utility model mid-game monic embodiment cross section structure schematic diagram.
In figure: 1, disk body; 2, dish is first; 3, outside solder side; 4, inner side solder side.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Fig. 1 ~ Fig. 2, the utility model embodiment provides a kind of diamond thin-wall drill bit matrix terminal pad, comprise disk body 1 and dish first 2, be characterized in, disk body 1 center is provided with through hole, and through hole is provided with internal thread, and dish first 2 is provided with corresponding external screw thread to disk body 1 link, both are threaded connection, and the outer be threaded welding.
As further technical scheme, internal thread is M45 × 2 internal thread.
As further technical scheme, the chamfering outer that it is highly 4.5mm that the outboard end of disk body 1 through hole is provided with, angle is 45 °.
As further technical scheme, the outside solder side 3 of disk body 1 is 0.5mm with the vertical range of disk body lateral surface; Inner side solder side 4 outside disk body medial surface is connected with dish first 2 is inner concave, and radius is 3mm, arc length is 18.84mm.
By the test to diamond thin-wall drill bit torque magnitude suffered by matrix in various environment for use and its use procedure in the utility model, the acrotorque that compute matrix terminal pad will bear, the shape of design disk body 1 planform and solder side and thickness, thus in use can not there is the problem that getting loose appears in weld in guarantee terminal pad.
As further technical scheme, the cross section of dish first 2 is the one in equilateral triangle, square, regular pentagon, regular hexagon or octagon.
It is equilateral triangle, square, regular pentagon, regular hexagon, octagon various structures shape that the utility model mid-game head 2 can be designed as cross section, difform dish and standard component disk body 1 combinations produce can be selected as required, therefore can produce in a large number in process of production and the disk body 1 of operating level part, produce difform dish first 2 more according to demand, finished product terminal pad can be obtained after combination, welding, substantially increase production efficiency.
The utility model provides a kind of technique manufacturing diamond thin-wall drill bit matrix terminal pad, comprise, the first 2 split manufactures of dish of the standard disk body 1 of diameter 80mm and different cross section and both be threaded after inside and outside connection external welding, welding manner is CO
2protection weldering, obtains finished product terminal pad.
In the utility model, disk body 1 and the preferred CO of first 2 welding manner of dish
2protection weldering, has that wire melting is fast, without features such as molten slag removals, the comparable manual metal-arc welding of efficiency improves 2.5-4 doubly; The chances are 1/2 of the manual electric arc welding of welding cost its integrated cost low; Weldment post welding distortion is little, and cracking resistance is good, is applicable to plate sheet welding; Higher rust-proofing ability, can save non-cutting times a large amount of in production,
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
