Description

A kind of groove type brazed shank tool

Technical field

The utility model is related to hard alloy cutter welding processing technical fields, and in particular to a kind of groove type welding knife Tool.

Background technology

It is well known that hard alloy bar is to enter combination formula by yttrium and form valuable raw material, it is existing Such material applications at most aspect is the manufacture of Integral alloy cutter.And in real production manufacturing, it is bigger to specification (i.e. straight Diameter is larger) cutter or require structure lengthen cutter (unconventional cutter) can not possibly completely using whole hard alloy material come Manufacture.Because first, hard alloy Costco Wholesale is high, is 3~10 times of universal cutter material.Unconventional cutter price is normal hard 1~2 times of matter alloy cutter material.Second, even if being fabricated to Integral alloy cutter as required, using effect may not be with its costliness Cost price it is directly proportional.

In production application, not amplify the cost of charp tool, frequently with ordinary carbon steel and hard alloy butt welding side Formula reduces to reduce using burden to solve cost problem.Usual hard alloy cutter welding structure is cutting edge portion using opposite The shank of tool is made in wearable hard alloy material firmly, non-blade port part using the cheap common steel processed of relative intensity function admirable Portion.There are one can be connected with each other mechanism between the two.It mutually organically blends, welds together by feat of intermediate medium.General feelings Under condition, there is hard cemented carbide material to be formed with a boss element center connection structure in mechanical processing, corresponding thereto It is the steel body that there is toughness blind mortise shape is constituted compared with good material that peripheral part, which should be coordinated, then.

Accompanying problem is that a series of problems, such as butt welding structure, intensity, quality.Under butt welding structure same case, Cost, intensity, mass parameter are related using high-end technology content to butt welding equipment.From the perspective of from another angle, if butt welding equipment at For preset parameter, butt welding cost also just determines substantially.And the influence factors such as butt welding Strength Mass have close pass with welding structure Connection.

In actual production, butt welding structure is very limited.And institute is deposited using butt welding structure and cutter work condition mode In direct correlation.That is it is not that can show welding structure can meet all cutter work shapes of adaptation State.From welding structure with from the point of view of relationship between quality, welding quality and the cutter use state of welded joint structure have close pass System.

Utility model content

The purpose of this utility model is to provide a kind of simple in structure, easily manufactured, can effectively promote welding quality, simultaneously Reduce material cost, the groove type brazed shank tool to economize on resources.

The utility model is achieved through the following technical solutions：

A kind of groove type brazed shank tool, including cylinder matrix and handle of a knife, described matrix one end are formed with "-" type boss, institute It states handle of a knife side and offers "-" type groove, the fit depressions on the boss and handle of a knife of described matrix, the groove both sides are equal Stress relief grooves are offered, the handle of a knife is ordinary carbon steel, and described matrix is hard alloy bar.

Further, each cross-sectional width size of boss in described matrix is consistent.

Further, described matrix is structure as a whole with boss.

Further, the stress release flute length 10mm, wide 1.5mm, depth 1.5mm.

The utility model has the beneficial effects that：

It is simple for process when 1, manufacturing, it is easy to control；

2, the utility model proposes structure be suitable for solid carbide drill class cutter；

3, the stress relief grooves on handle of a knife eliminate welding heating and different materials coefficient of thermal expansion generates stress, prevent out It splits, simultaneously because the presence of this slot, the solder melted in welding can be stored in slot, the stream of solder when can also prevent from welding It loses；

Semi-enclosed state can be visually seen whether solder fills completely when 4, welding, if being also avoided that in welding Situation hard to find when phenomena such as existing slag inclusion, stomata is lack of penetration；

5, from detection, appearance only need to be observed, can substantially view weld defect situation, detection is relatively easy.

Description of the drawings

Fig. 1 is the structural schematic diagram of the utility model.

Wherein：1, handle of a knife, 2, stress relief grooves, 3, matrix, 4, boss, 5, groove.

Specific implementation mode

Illustrate to be described further the utility model below in conjunction with the accompanying drawings.

As shown in Figure 1, a kind of groove type brazed shank tool, including cylinder matrix and handle of a knife, described matrix one end are formed with one Font boss, the handle of a knife side offer "-" type groove, and the fit depressions on the boss and handle of a knife of described matrix are described Groove both sides offer stress relief grooves, and the handle of a knife is ordinary carbon steel, and described matrix is hard alloy bar.

In the technical scheme, each cross-sectional width size of boss in described matrix is consistent.

In the technical scheme, described matrix is structure as a whole with boss.

In the technical scheme, the stress release flute length 10mm, wide 1.5mm, depth 1.5mm.

In the technical scheme, the welding process of cutter is：Handle of a knife 1 is clamped in fixture bottom end, high frequency with special fixture 700 degree of heating, 5 seconds time, 700 degree of high-frequency heating, scaling powder is uniformly applied on welding surface by 5 seconds time, after thawing, base Body 3 is put down from the guide sleeve of fixture lower end, makes boss on matrix and handle of a knife groove to just, heating 900 ~ 100 degrees Celsius, when heating Between 10 seconds, so that the molten material of solder is dissolved into certain welding position.Stop heating, waits for take the cutter welded from fixture within 10 seconds Go out, put incubator into, cooling, incubator is preheating to 300 degrees Celsius, puts the cutter welded into incubator, holding 300 is Celsius Then degree, constant temperature 4 ~ 6 hours cut off incubator power supply, until cutter cooling is taken out.

With the cutter of novel proposition, when manufacture, is simple for process, easy to control for this；Structure is suitable for solid carbide drill Class cutter；Stress relief grooves on handle of a knife eliminate welding heating and different materials coefficient of thermal expansion generates stress, prevent from cracking, together When due to this slot presence, in welding, the solder that melts can be stored in slot, the loss of solder when can also prevent welding；Weldering Semi-enclosed state can be visually seen whether solder fills completely when connecing, if being also avoided that in welding slag inclusion, stomata occur Situation hard to find when phenomena such as lack of penetration；From detection, appearance only need to be observed, can substantially view weld defect Situation, detection are relatively easy.

The embodiment of the utility model above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously Cannot the limitation to the utility model patent range therefore be interpreted as.It should be pointed out that for the ordinary skill of this field For personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these belong to this The protection domain of utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
