Description
Technical field
The utility model relates to threading tool design and manufacturing technology field, is specifically related to a kind of Novel spiral groove screw tap.
Background technology
In hole processing technology, frequent employing be that the exciting processed springs bearing of straight slot screw tap carries out tapping, the unsharp problem of thread is there is after tapping, and only there is incessantly phenomenon by plug thread gauge detection in part screw, cause every batch to perform one hundred percent inspection, check that workload is excessive, product once hands over inspection qualification rate only about 60%, cause the Repair to defective screw sealing weld tapping secondary operations again, have a strong impact on the production efficiency of product and increase production cost.
Utility model content
For the deficiency that prior art exists, the utility model provides a kind of chip removal smooth, and chip can not remain, and wedging bottom outlet is easy, the good and Novel spiral groove screw tap that productivity ratio is higher of machinability.
The utility model is achieved through the following technical solutions:
A kind of Novel spiral groove screw tap, comprises leading part, cutting tip, calibrated section and shank; Be provided with neck between described leading part and cutting tip, the tail end of described shank is provided with square toes, and described leading part length is 15-25mm.
Compared with prior art, the beneficial effects of the utility model are: adopt the tapping of Novel spiral groove screw tap of the present utility model motor-driven processed springs bearing, chip is made to flow out backward during tapping, chip removal is smooth, and chip can not remain, and wedging bottom outlet is easy, there is good machinability, and product once hands over inspection qualification rate to reach 100%, improves production efficiency, reduces production cost.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
In accompanying drawing: 1. leading part; 2. neck; 3. cutting tip; 4. calibrated section; 5. shank; 6. square toes.
Detailed description of the invention
A kind of Novel spiral groove screw tap, comprises leading part 1, cutting tip 3, calibrated section 4 and shank 5; Be provided with neck 2 between leading part 1 and cutting tip 3, the tail end of shank 5 is provided with square toes 6, and leading part 1 length is 15-25mm.
In sum, be only preferred embodiment of the present utility model, not be used for limit the utility model implement scope, all equalizations of doing according to shape, structure, feature and the spirit described in the utility model right change and modify, and all should be included in right of the present utility model.
