Abstract
The utility model relates to a composite blade-surface screw tap, and discloses a composite tool for machining a blade-surface screw path. The composite tool comprises a screw blade body and a screw handle, wherein the screw blade body is integrated with the screw handle and provided with a plurality of integrated screw blade strips, and a screw blade surface is arranged on the front surface of each screw blade strip. The composite tool is characterized in that small screw blade surfaces are formed on the screw blade surfaces at rounding chamfers of the screw blade strips and near the screw blade strips, the other screw blade surfaces of the screw blade strips near the screw handle part are original screw blade surfaces, and an included angle a between the small screw blade surfaces and a screw top is larger than an included angle b between the original screw blade surfaces and the screw top. By adopting the technical scheme, the composite tool can enhance the wear-resisting performance of the screw tap and prolong the service life thereof; and by adopting a preferable manner, the composite tool can enable the screw tap to have the high intensity machining for a long time, and improve the machining quality.
Description
Technical field
The utility model relates to a kind of screw tap, relates to a kind of compound cutting face screw tap specifically, and the technical program is used in the silk hole processing of machining to workpiece.
Background technology
At present, spiral tap that uses in the machining or straight trough screw tap are to be made of silk sword, chamfering, chamfering blades, silk handle, the cutting edge face that silk sword, chamfering blades are same group is roughly on a plane or same helicoid, silk sword face silk top angle is too small, though silk sword face and groove bottom excessively have concave surface, silk sword face and concave surface are the faces of smooth excessiveness.These screw taps when the higher workpiece of Material Processing hardness, viscosity, exist can't process, screw tap is fragile, screw tap damages, break at the defective that influences product quality in the workpiece, and, because the silk sword face of each group is formed by single, silk sword easy fracture then when angle is too sharp keen between silk sword face and the silk top, occur the silk handle when angle is excessive between silk sword face and the silk top and clamp that Tool Room torsion is excessive easily to cause the whole fracture of screw tap, in workpiece, cause workpiece quality impaired even scrap.
Summary of the invention
The utility model is exactly to propose in view of the above-mentioned problems, is purpose so that a kind of novel compound cutting face screw tap to be provided, this kind cutter radiating efficiency height, and wear-resistant, the life-span is long.
In order to achieve the above object, the utility model adopts following technical proposals:
Compound cutting face screw processing tool, comprise a sword body and silk handle, this sword body and silk petioliform become one, silk sword body one be provided with a plurality of sword bars, the front of each sword bar have a silk sword face it is characterized in that a sword bar chamfering place and near the silk sword face of silk sword bar leave a little silk sword face, all the other silk sword faces near silk shank silk sword bar are precursor sword face, and the angle a on little silk sword face and silk top is greater than the angle b on precursor sword face and silk top.
Preferably, described compound cutting face screw processing tool protrudes along the relative precursor sword of little silk sword face face on the cutting direction.
Preferably, described compound cutting face screw processing tool protrudes along the relatively little silk of cutting direction precursor sword face sword face.
Preferably, at the bottom of described precursor sword face silk, leave the reinforcement platform that certain angle is arranged with precursor sword face.
Preferably, at the bottom of described little silk sword face silk, leave the reinforcement platform that certain angle is arranged with little silk sword face.
Preferably, leave one in described precursor sword face, little silk sword face silk bottom and the reinforcement platform of certain angle is arranged with precursor sword face, little silk sword mask.
Preferably, described silk sword body is a kind of in the following type; Tapering silk sword body, raw silk rings sword body, taenidium sword body description of drawings

The specific embodiment
Technical scheme and preferred implementation thereof below in conjunction with the detailed explanation the utility model compound cutting face screw processing tool of accompanying drawing.
As shown in Figure 1, this compound cutting face screw processing tool comprises a sword body 1 and silk handle 2, this sword body 1 and silk handle 2 form as one, silk sword body 1 one be provided with a plurality of sword bars 3, there is a silk sword face front of each sword bar, the silk sword face of silk sword bar was left a little silk sword face 5 near silk sword bar 3 chamferings 4 places reached, and the silk sword face of 2 silk swords of close silk handle bar is a precursor sword face 6, and the angle a on a little silk sword face 5 and a top 7 is greater than the angle b on precursor sword face 6 and silk top 7.
In the above structure, because little silk sword face 5 and precursor sword face 6 be not on a face, little silk sword face 5 and the angle of an angle on top 7 greater than precursor sword face 6 and silk top 7, the little silk of main stress part sword face has strengthened scuff resistance in the technical program processing thereby make, also be not easy to make its whole fracture, little silk sword face comprises near the silk sword face of chamfering 4 a sword bar, and therefore little silk sword face length degree is longer than the length of chamfering in the prior art, has so just reduced the cutting hardness of little silk sword.Prolong the life-span, and in process, kept high strength always.
As shown in Figure 3, on the basis of embodiment 1 structure, at the bottom of 6 in precursor sword face, process one and have the reinforcement platform 8 of certain angle with precursor sword face 6, strengthen platform 8 and not only increase the thermolysis of cutter work in-process, simultaneously, make little silk sword face 5 more forward stressed more obvious than precursor sword face 6 owing to strengthen platform 8, because of little silk sword face 5 and silk top 7 angles increase, can make the cutter work in-process keep high strength, working ability is stronger always, and crudy is higher.
As shown in Figure 5, on the basis of embodiment 1 structure, at the bottom of 5 in little silk sword face, process one with little silk sword face 5 have the reinforcement platform 8 of certain angle ', strengthen platform 8 ' the increased thermolysis of cutter work in-process, simultaneously, because reinforcement platform 8 ' make little silk sword face 5 stressed more obvious by the back than precursor sword face 6 makes precursor sword and precursor sword face 6 positioning actions more obvious.
As shown in Figure 7, on the basis of embodiment 1 structure, at the bottom of 5 in precursor sword face 6, little silk sword face, process one and have the reinforcement platform 8 of certain angle with precursor sword face 6, little silk sword face 5 "; strengthen platform 8 and " increased the thermolysis of cutter work in-process, make the working ability of cutter stronger, can keep high strength by work in-process, crudy is higher always.
As shown in Figure 9, on the basis of embodiment 1 structure, protrude along the little silk of cutting direction sword face 5 relative precursor sword faces 6.
As shown in figure 11, on the basis of embodiment 1 structure, protrude along cutting direction precursor sword face 6 relatively little silk sword faces 5.
Above embodiment only be the technical program preferred embodiment; certainly the technical program also has other embodiment; present specification is enumerated no longer one by one, and the specific embodiment and derivative schemes thereof that the utility model claim is limited all fall into protection domain of the present utility model.
