Abstract
The utility model discloses a segmented screw tap which is less prone to block a to-be-processed hole and is high in processing quality. The segmented screw tap comprises a cylindrical body which comprises a tapping portion, a chip storage portion and a correction portion from bottom to top. Each of the tapping portion and the correction portion is provided with a threaded chip cutting edge, and a chip storage groove with an arc-shaped cross section is arranged on the outer surface of the chip storage portion and axially along the cylindrical body. By means of the segmented design, the screw tap is partitioned into the topmost tapping end, the chip storage portion used for storing waste chips at the topmost end and the correction portion, so that the to-be-processed hole is less prone to be blocked by the waste chips, tapping space is distributed reasonably, and processing quality is improved.
Description
Technical field
The utility model relates to a kind of screw tap of segmented design.
Background technology
In known technical field, screw tap generally is used for the common internal thread on nut processing or other parts, machine tap typically refers to high-speed steel geared tap, be applicable to tapping on lathe, set tap refers to that carbon tool steel or alloy tool steel roll the tooth screw tap, be applicable to manual tapping, no matter be tapping on hand tapping or the lathe, screw tap scrap rate in the lowermost end section of tapping when reality is used is generally larger, the situation that scrap stops up hole to be processed very easily occurs, so that can't proceed to process or need to process by larger revolving force, very easily affect simultaneously the quality of processing.
The utility model content
The technical problems to be solved in the utility model is: a kind of difficult obstruction hole to be processed, the screw tap that crudy is good are provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of segmented screw tap, comprise cylindrical body, described cylindrical body is divided into tapping section, storage bits section and correction portion from the bottom to top successively, be equipped with the screw thread cutting edge on described tapping section and the correction portion, be provided with the storage bits groove that cross section is circular arc along the axial of described cylindrical body and at the outer surface that stores up bits section.
The beneficial effects of the utility model are: the utility model is by adopting the design of segmented, screw tap is divided into the top of tapping, scrap part and the retouch of storage top, so that scrap be difficult for to stop up for machining hole, simultaneously reasonable distribution the space of tapping, improved the quality of processing.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is cross-sectional view of the present utility model.
Among the figure: 1. cylindrical body, 1-1. tapping section, 1-2. storage bits section, the 1-3. correction portion,
1-4. storage bits groove.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of segmented screw tap of the utility model as depicted in figs. 1 and 2, comprise cylindrical body 1, described cylindrical body 1 is divided into the 1-1 of tapping section, the storage bits 1-2 of section and correction portion 1-3 from the bottom to top successively, be equipped with the screw thread cutting edge on the described tapping 1-1 of section and the correction portion 1-3, be provided with the storage bits groove 1-4 that cross section is circular arc along the axial of described cylindrical body 1 and at the outer surface that stores up the bits 1-2 of section.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
