Abstract
A novel screw tap mainly comprises a cone, wherein a through hole which penetrates through the cone is formed inside the cone along an axis of the cone, and inner threads are arranged inside the through hole. The novel screw tap has the advantages of being simple in structure, wide in range of application, notable in cooling effect, capable of enabling the screw tap left in a workpiece to be taken out easily with a screw driver once the screw tap is fractured, time-saving, labor-saving, and convenient to operate.
Description
Technical field
The utility model relates to a kind of hardware ﹠ tools, is a kind of screw tap specifically.
Background technology
In machining, modal a kind of method with tap tapping, and screw tap can produce a large amount of heat at work, the heat that produces all raises the temperature of screw tap and workpiece to be machined, adds the factors such as misoperation, and the screw tap fracture is inevitable, the screw tap that fracture also usually occurs remains in the situation such as can't take out in the workpiece, just must take out the screw tap of fracture in order not scrap workpiece, waste time and energy and do not say, the taking-up effect is often not fully up to expectations; In addition, for reducing the temperature in the tapping process, existing technical scheme is directly to wash by water to the working position, and this cooling-down effect is undesirable.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of cooling-down effect remarkable, the Two-end Tap Applied that can easily take out residual fraction when the screw tap fracture occurs.
The purpose of this utility model is achieved by the following technical solution: it mainly comprises a cone, offers one in the described cone along the cone axial line and runs through the through hole of cone; Be provided with internal thread in the described through hole.
The beneficial effects of the utility model are: it simple in structure, and the scope of application is extensive, and cooling-down effect is remarkable, and in case the situation of screw tap fracture occurs, can take out with the screw tap that screwdriver will remain in the workpiece like a cork, and is time saving and energy saving, easy to operate.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: as shown in Figure 1, it mainly comprises a cone 1, offers one in the described cone 1 along cone 1 axial line and runs through the through hole 2 of cone; Be provided with internal thread 3 in the described through hole.
In use, the effect of through hole can be used as ventilating duct on the one hand, and working portion is dispelled the heat as early as possible, can directly be filled in the through hole with cooling fluid on the other hand, and working portion is directly cooled off, and effect is very obvious; In case the screw tap phenomenon of rupture occurs, can also utilize the screw thread in the through hole with common screwdriver, the residual screw tap that breaks at inside workpiece is easily taken out, time saving and energy saving.
Certainly, above-mentioned explanation is not limitation of the utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in scope of the present utility model, the variation of making, change and add or replace, all should belong to protection domain of the present utility model.
