Abstract

The utility model provides an embedded butt type tool, which comprises a tool shank and an edge part; wherein the periphery of one end of the edge part is provided with edges which can cut or drill on the surface of a preset base material; the other end of the edge part which is far from the edges is provided with an insert end; the surface of one end of the tool shank is concavely provided with a socket; the insert end of the edge part is inserted in the socket; the diameter of the socket is more than that of the insert end; and welding material is filled in the gap formed between the periphery of the insert end and the inner wall of the socket. The strength and reliability of the weld are greatly improved, the process of smoothening the end surface of the jointing material is simplified, and the affection of longitudinal stress and transverse stress can be effectively inhibited at the same time.

Description

A kind of embedding flushes the formula cutter

Technical field

The utility model relates to a kind of embedding and flushes the formula cutter, relates in particular to a kind of handle of a knife and blade utilization embedding of cutting or holing employed cutter and flushes the cutter that mode combines.

Background technology

General cutting or boring cutter are integrally formed made with the material of high rigidity, and in use for some time, can cause the wearing and tearing of blade position or the fracture of cutter, and after this blade position breakage, it will be abandoned as scrap, cause the waste of resource, and the high rigidity material not only is difficult to processing and price is very expensive, so process time is quite long and the meeting consume material, cause manufacturing cost high and can't reduce, be unfavorable for economic benefit; Moreover, the handle of a knife position of cutter does not only need the material of high rigidity for work board clamping, so, the integrally formed made cutter of the material of high rigidity, it itself is exactly a kind of waste of resource, this is the production cost problem that the cutter industry is faced of producing at present, and therefore this industry is is there's no one who doesn't or isn't deliberately researched and developed the method that reduces cost at present.

Summary of the invention

Main purpose of the present utility model is to provide a kind of embedding to flush the formula cutter, utilize made blade part of unlike material and handle of a knife portion, assemble with the grafting welding manner, with the reduction cost of charp tool, and can effectively save resource, and the cutter of pegging graft and being assembled into, can increase the area of combination, and then significantly promote the intensity and the reliability of weld, and simplify the smooth procedure for processing of end face of grafting material, and can effectively suppress vertically simultaneously and the influence of lateral stress.

For reaching above-mentioned purpose, the utility model provides a kind of embedding to flush the formula cutter, be provided with handle of a knife portion and blade part, described blade part one end outer rim has the blade that can cut or hole at default substrate surface, described blade part is provided with inserted terminal at the other end away from blade, described handle of a knife portion one end surfaces is concaved with inserting groove, the inserted terminal of described blade part is plugged in the inserting groove, and the diameter of inserting groove is greater than the inserted terminal diameter, and filled up wlding in the outer rim of inserted terminal and the formed gap location of inner edge of inserting groove.

Compared with prior art, embedding described in the utility model flushes the formula cutter, utilize made blade part of unlike material and handle of a knife portion, with the assembling of grafting welding manner, to reduce the cost of charp tool, and can effectively save resource, and the cutter of pegging graft and being assembled into can increase the area of combination, and then significantly promote the intensity and the reliability of weld, and the smooth procedure for processing of the end face that simplifies grafting material, and can effectively suppress vertically simultaneously and the influence of lateral stress.

The specific embodiment

See also Fig. 1 to shown in Figure 2, find out that by knowing among the figure embedding of the present utility model flushes the formula cutter and is provided with blade part 1 and handle of a knife portion 2, wherein:

Described blade part 1 is made with the high rigidity bar, and described blade part 1 one ends have inserted terminal 11.

Described handle of a knife portion 2 is made with the bar that is different from described blade part 1 material, and described handle of a knife portion 2 one end surfaces are concaved with inserting groove 21, and the diameter of described inserting groove 21 is greater than the inserted terminal 11 of described blade part 1.

See also Fig. 2 and shown in Figure 3, find out by knowing among the figure, when the utility model in group during structure, inserted terminal 11 with blade part 1 inserts the inserting groove 21 of handle of a knife portion 2 earlier, and because of the diameter of the inserting groove 21 of handle of a knife portion 2 diameter greater than the inserted terminal 11 of described blade part 1, therefore, between the inner edge of the outer rim of inserted terminal 11 and inserting groove 21, can be formed with the gap, and fill up wlding 3 in the outer rim of inserted terminal 11 and the formed gap location of inner edge of inserting groove 21, and utilize high-temperature soldering, and wlding 3 is combined closely the inserting groove 21 of handle of a knife portion 2 with the inserted terminal 11 of blade part 1, promptly finish of the present utility model group of structure.

See also Fig. 3 and shown in Figure 4, find out by knowing among the figure, blade part 1 and handle of a knife portion 2 after the described solder bond, go out blade 12 at blade part 1 away from the other end outer rim attrition process of inserted terminal 11, allow the user when using the utility model, handle of a knife portion 2 can be held on the board (not shown), and allow board utilize the blade 12 of blade part 1, come base material (not shown) surface is cut or holed.

Because when blade part 1 of the present utility model combines with handle of a knife portion 2, utilize wlding 3 closely in conjunction with the outer rim of inserted terminal 11 and the inner edge of inserting groove 21, make blade part 1 and handle of a knife portion 2 when combining, can increase the area of combination, and then significantly promoting the intensity and the reliability of weld, and the part that exposes of wlding 3 only can result from inserting groove 21 surface periphery of handle of a knife portion 2, can effectively simplifying the smooth procedure for processing of end face of wlding 3, and can effectively suppress vertically simultaneously and the influence of lateral stress.

More than explanation is just illustrative for the utility model; and it is nonrestrictive; those of ordinary skills understand; under the situation of the spirit and scope that do not break away from claims and limited; can make many modifications, variation or equivalence, but all will fall in the protection domain of the present utility model.
