Technical field
The utility model relates to a kind of hole punched device, especially a kind of device that is used for the hexagonal hole of punching press SOC.HD. cap screw.
Background technology
SOC.HD. cap screw is widely used in fields such as Aeronautics and Astronautics, boats and ships, electronics, defence owing to possess good positioning and locking effect.Its relevant criterion all has special requirement to the accurate positioning of SOC.HD. cap screw, convenient and swift, high conformity.This just proposes high request to the uniformity of the interior hexagonal hole size of SOC.HD. cap screw, must be interior hexagonal hole size Control within a very tight margin of tolerance.So the processing method of the interior hexagonal hole of SOC.HD. cap screw is particularly important.Because being the hexagon with special use, the interior hexagonal hole of SOC.HD. cap screw is used; Six square chi cun tolerance is very tight, and is low according to traditional extruding, slotting or electric discharge machining method efficient, and processing cost is high; And the uniformity less stable of finished size, there is bigger mismachining tolerance.Solve that above efficient is low, the size problem of unstable, the processing of SOC.HD. cap screw and measure and to possess following five characteristics: 1, simple and easy to operate.2, has versatility.3, accurate positioning.4, processing cost is low.5, efficient is high.
Summary of the invention
The problem that the utility model will solve provides a kind of hole punched device, can be fast, accurately the interior hexagonal hole of six side's screws be carried out punch process.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of hole punched device comprises die shank, drift, die shank gland, punch die; Drift is fixed by die shank and die shank gland; Also comprise the gland mould, said gland mould upper surface be provided with one with treat the corresponding cavity of punching screw head profile, the lower surface has flat recess; Inside has a cannelure, and cannelure and flat recess connect; Have the through hole that is used for through shank of screw portion on the said punch die, its side is provided with cannelure, and its side also is provided with two rectangle planes parallel to each other, and cannelure and rectangle plane connect; Said gland mould is installed on the punch die, and by the cannelure location, SOC.HD. cap screw is fixed on the punch die by the gland mould, the cavity center axis of said gland mould and the central axis conllinear of punch die through hole.
Further, the diameter dimension of the little cannelure on it of width dimensions of the flat recess on the said gland mould, two sides of flat recess central axis relative and the gland mould is symmetrical.
Further, the central axis of two corresponding punch dies of rectangle plane on said punch die symmetry, and perpendicular to the upper surface of punch die.
Further, two rectangle plane spacings on the said punch die equal the width value of gland mould flat recess.
Advantage and the good effect that the utlity model has are: adopt technique scheme, processing method is easy and simple to handle, and efficient is high, and the product processed dimensional accuracy is high, high conformity, and cost is low, has excellent popularization and is worth.

The specific embodiment
As shown in Figure 1, the utility model is a kind of hole punched device, comprises die shank 1, drift 2, die shank gland 3, punch die 6; Drift 2 is fixing with die shank gland 3 by die shank 1, also comprises gland mould 5, and is as shown in Figure 2; The upper surface of gland mould 5 be provided with one with the corresponding cavity 51 of the head configuration of treating punching screw 4; The lower surface has flat recess 53, and inside has a cannelure 52, and cannelure 52 connects with flat recess 53; As shown in Figure 3, have the through hole 61 that is used for through shank of screw portion on the punch die 6, its side is provided with cannelure 62, and its side also is provided with two rectangle planes parallel to each other 63, and cannelure 62 connects with rectangle plane 63; Gland mould 5 is installed on the punch die 6; By cannelure 52,62 location; Treat that punching screw 4 is fixed on the punch die 6 by gland mould 5, more accurate for gland mould 5 is located, the central axis conllinear of cavity 51 central axis of gland mould 5 and the through hole 61 of punch die 6.
The cannelure 52 of gland mould 5 is in order to treat punching screw 4 stable and accurate being fixed on the punch die 6; So the diameter dimension of the little cannelure 52 on it of the width dimensions of the flat recess 53 on the gland mould 5, two side planes of flat recess 53 central axis relative and gland mould 5 is symmetrical.Gland mould 5 plays the location and the effect of the material returned when the hexagonal hole of punching press SOC.HD. cap screw, therefore obtained application widely, and the accurate positioning of gland mould, quick and easy for installation, high conformity, processing cost is low, efficient is high.
The central axis of two rectangle planes, the 63 corresponding punch dies 6 on the punch die 6 symmetry, and perpendicular to the upper surface of punch die 6; Two rectangle plane 63 spacings on the punch die 6 equal the width value of the flat recess 53 of gland mould 5.
In the present embodiment; Punch die 6 is fixed on the backing plate 7, the rod end of treating punching screw 4 is passed the through hole 61 of punch die 6, the flat recess 53 with gland mould 5 is connected with two of punch die 6 parallel rectangle planes 63 then; At this moment; The head of treating punching screw 4 just in time is embedded in the cavity 51 of gland mould 5 upper surfaces, and again with gland mould 5 half-twists, the cannelure 52 on the gland mould 5 cooperates the location with cannelure 62 on the punch die 6 like this; Gland mould 5 just will be treated punching screw 4 being fixed on the punch die 6 steadily, and can not deviate from; Die shank 1 is fixed on drift 2 on the punch press with die shank gland 3; After punching finished, when drift 2 left SOC.HD. cap screw, gland mould 5 had stoped the SOC.HD. cap screw rising; When drift 2 lift leave gland mould 5 after, gland mould 5 half-twists, remove gland mould 5 again; Take out SOC.HD. cap screw, the hexagonal hole punching press finishes in six side's screws; According to this to the hexagonal hole punch process of next SOC.HD. cap screw.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
