Abstract

The utility model relates to a punching mould of hexagonal pass in soket head cap screw, including terrace die, die and die sheath, tetragonal body die center is cylindrical cavity, and tetragonal body die sheath center is the tetragonal body cavity, and the die sheath overlaps outside the die, and the terrace die is cylinder and outer hexagon looks connection structure, the cylinder of outer hexagon front end for having the cone angle. The utility model discloses simple structure, with low costs, the punching is effectual. The problem that makes purchase of nothing department and the customize of nothing department obtains solving, guarantees the parts machining quality, satisfies the product requirement.

Description

The punching die of soket head cap screw inner hexagonal hole type

Technical field

This utility model relates to the frock of processing soket head cap screw inner hexagonal hole type, particularly to the punching die of soket head cap screw inner hexagonal hole type.

Background technology

Having a kind of part dental lamina screw in the hydraulic tongs product that my company produces, the head of screw outside diameter of this part has tolerance (see accompanying drawing 1).Owing to buying nowhere, as tailor-made again owing to also not having made to order nowhere in batches to Standard Component Factory；If changing a social system by standard screws, also cannot be carried out owing to dimensions is improper, actual production causes a neither big nor small difficult problem.

Summary of the invention

Technical problem to be solved in the utility model is to provide the punching die of a kind of soket head cap screw inner hexagonal hole type, and simple in construction, cost are low, punching is effective.Complete the processing of soket head cap screw.

For achieving the above object, this utility model realizes by the following technical solutions:

The punching die of soket head cap screw inner hexagonal hole type; including punch, die and die sheath; tetragonal body die center is cylindrical cavity; tetragonal body die sheath center is tetragonal body cavity; die sheath is enclosed within outside die; punch is that cylinder is connected with outer-hexagonal body structure, and outer-hexagonal body front end is the cylinder with cone angle.

Described die and die sheath matched in clearance.

Described die height is more than the degree of depth of die sheath center tetragonal body cavity.

Compared with prior art, the beneficial effects of the utility model are:

This utility model simple in construction, cost are low, punching is effective.Make the problem bought nowhere and have made to order nowhere be solved, it is ensured that part crudy, meet product requirement.

Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is further illustrated:

Such as Fig. 2-6, the punching die of soket head cap screw inner hexagonal hole type, including punch 1, die 2 and die sheath 3; tetragonal body die 1 center is cylindrical cavity; tetragonal body die sheath 3 center is tetragonal body cavity, and die sheath 3 is enclosed within outside die 2, die 2 and die sheath 3 matched in clearance.Die 2 height is more than the degree of depth of die sheath 3 center tetragonal body cavity.Punch 1 is connected with outer-hexagonal body structure for cylinder, and outer-hexagonal body front end is the cylinder with cone angle.

Dental lamina screw processing method; sawing round steel blanking; the pre-hole of hexagonal in boring; turning, less than die centered cylinder cavity diameter, is used grilled gun heated parts, is put into die; it is enclosed within outside die with die sheath; clamp with bench vice after ajusting, punch press goes out inner hexagonal hole type with punch, modified, car finished product, surface treatment.

Described above is only ultimate principle of the present utility model, not this utility model is imposed any restrictions, and it is carried out equivalent variations and modification by every foundation this utility model, all within the category of the art of this patent protection scheme.
