Abstract
The invention provides a new punching head structure. The new punching head structure is characterized by combining the deformation characteristic of a common punching and extruding process. According to the new punching head structure, a step and an inclined edge are added to a cutting edge on the basis of the conventional mould, the height of the step is the fracture depth of first punching, and the step and the inclined edge mainly achieve the same punching effect as that of conventional punching; the value of a taper angle of the inclined edge is subjected to parameter optimization through an orthogonal test method, a suitable size range is obtained, and the inclined edge part mainly achieves an effect of extruding and repairing a hole. The new punching head structure can improve the hole punching shape and quality by modifying the process under the conditions of common punching, so that a punching part with a higher shearing surface and perpendicularity is obtained.
Description
Technical field
The present invention is specifically related to a kind of drift new construction, belongs to mold machining technology field.
Background technology
There is the little problem with the big shape quality defect of perpendicularity low two of euphotic belt in conventional pierce, but in actual production, we wish that again the blanking part obtained has higher euphotic belt and relatively high verticality, but common stamping is difficult to the requirement that this is high, especially when shear surface is had more than the requirement for height that common stamping can reach by some part.Then, being developed the methods such as trimming, fine, make workpiece section and precision be greatly improved, but it needs increase manufacturing procedure or adopt expensive equipment, adds economic cost, this is incompatible with the production status of most enterprises and target call.Based on this present situation with produce actual needs, people always want to can when common stamping amendment technique to improve punching quality.
Summary of the invention
The main Quality existed in view of conventional pierce is that euphotic belt is little and the big defect of perpendicularity low two, but in actual production, the blanking part that we are primarily intended to obtain has higher shear surface, when shear surface is had more than the requirement for height that common stamping can reach by some part, this weak point that common stamping is just difficult to, it is contemplated that propose a kind of drift new construction, this drift combines the deformation characteristics of common stamping and extruding, it can improve punching shape quality when common stamping, it is thus achieved that has the blanking part of higher shear face and perpendicularity.
For achieving the above object, the technical scheme is that a kind of drift new construction, primary structure includes step and oblique sword, and described step primarily serves the stamping-out effect the same with conventional pierce, and it highly takes the degree of depth of the fracture of punching first.
Described oblique sword mainly can play the effect that crowded hole is repaired, the value of its oblique sword cone angle, carries out parameter optimization (30 degree, 45 degree, 60 degree, 75 degree) by the method for orthogonal test, obtains size optimal value 45 degree.
The actual gain of the present invention is: (1) this new construction can use on conventional press, it is not necessary to use expensive equipment, good economy performance.(2) this new construction can be modified technique to improve punching shape quality when common stamping, and then obtains the blanking part having higher shear face and perpendicularity.

Fig. 1 description of symbols: 1-drift, the oblique sword of 2-, 3-boss, the oblique sword tapering of 4-.
Detailed description of the invention
In order to the technical characteristic of the present invention, purpose and effect are more clearly understood from, now comparison accompanying drawing illustrates the specific embodiment of the present invention, but it is only preferred embodiment, is not intended to limit the essential scope of the present invention.
Below in conjunction with accompanying drawing, the present invention done detailed introduction: as it is shown in figure 1, a kind of drift new construction, be mainly made up of 1 drift, 2 oblique swords, 3 boss, 4 oblique sword cone angles.Drift 1 is arranged on gap-framepress punch, completes the function of stamping-out.
Oblique sword 2 mainly can play the effect that crowded hole is repaired, the value of its oblique sword cone angle 4, carries out parameter optimization (30 degree, 45 degree, 60 degree, 75 degree) by the method for orthogonal test, obtains size optimal value 45 degree.
Step 3 primarily serves the stamping-out effect the same with conventional pierce, and it highly takes the degree of depth of the fracture of punching first.
The foregoing is only the preferred embodiments of the present invention, be not intended to limit the present invention, for a person skilled in the art, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
Claims (2)
1. a drift new construction, primary structure includes step and oblique sword, and described step primarily serves the stamping-out effect the same with conventional pierce, and it highly takes the degree of depth of the fracture of punching first.
2. a kind of drift new construction according to claims 1, it is characterized in that described oblique sword mainly can play the effect that a crowded hole is repaired, the value of its oblique sword cone angle, parameter optimization (30 degree is carried out by the method for orthogonal test, 45 degree, 60 degree, 75 degree), obtain size optimal value 45 degree.
