Specific embodiment
It should be noted that in the case where not colliding, the feature in embodiment and embodiment in the invention can be mutually combined.
Below in conjunction with the accompanying drawings the specific embodiment of the invention is elaborated.
A kind of angle steel workpiece stamping mold, as depicted in figs. 1 and 2, including the upper die base 1 and lower die base 2 that are correspondingly arranged up and down；Punch 4 is connected with by screw 3 in the upper die base 1；Adjusting pad 5 is provided between the punch 4 and upper die base 1, is all gathered in the upper and lower surface of the adjusting pad 5 and is provided with height identical convex portion 6, had for air circulation space between adjacent projection 6；The lower die base 2 is provided with the groove 7 matched with the punch 4；The lower die base 2 is provided with the locating slot 8 of the angle steel workpiece 18 for laying to be processed；Positioning component 9 is installed in the locating slot 8.
The formula structure design it should be noted that lower die base 2 is formed in one, higher than split type structural strength, stability is more preferable, easy-to-use, durable, long service life.
Wherein, the positioning component 9 includes two location-plates 10 being oppositely arranged；Stage clip 11 is designed between 8 inwall of each described location-plate and locating slot.
Wherein, 10 upper end of the location-plate is provided with guiding surface 12, and when angle steel workpiece 18 to be processed is laid, angle steel workpiece under the guide effect of guiding surface 12 is more easy to enter positioning component, convenient and swift.
In addition, the positioning component 9 can also adopt second form, as shown in Figure 3, which includes the positional cylinder 14 of the pinch wheels 13 that can be rotated in vertical direction and promotion 13 horizontal movement of pinch wheels, angle steel workpiece is under the guide effect of pinch wheels 13, smoothly slide between two pinch wheels, pole length can be stretched out to change the dynamics of clamping by adjustment positional cylinder 14, it is ensured that locating effect.
To ensure the reliable and stable of punching course, antiskid plate 15 is removably installed in the bottom of the lower die base 2, and 15 lower surface of the antiskid plate is provided with some projections 16 with tip.Prevent from producing displacement because of punching press vibrations.
Wherein, the antiskid plate 15 is connected by screw in 2 bottom of the lower die base.Can be dismounted according to actual condition, such as on the ground that hard is smooth, it is impossible to during using with raised antiskid plate, screw disassembling can be screwed and fall down mold base 2.
Wherein, in order to prevent in punching course; together with being adhered between adjusting pad and punch or upper die base; it is difficult to clear up and dismantles; all gather in the upper and lower surface of adjusting pad 5 and be provided with height identical convex portion 6; and then reduce directly contact area between adjusting pad and punch or upper die base, and having between adjacent projection 6 for air circulation space, the ventilation passage gaps can prevent air in extrusion process to be excluded and be adhered together under gas pressure；In addition, when punch height is adjusted using multigroup adjusting pad, convex portion 6 can also prevent adjusting pad to be adhered each other together.
Wherein, prevent being adhered and bearing punching press strength Reducing distortion degree to take into account, the taper that convex portion is gradually reduced from the bottom up in cross section, the spacing between the summit of adjacent two convex portion are 0.05-2 millimeters, reach the effect of setting of gathering.
Wherein, general adjusting pad preferred rubber pad.
Wherein, the punch 4 is provided with the counterbore 17 for mounting screw 3, and so, screw 3 submerges in counterbore, and without prejudice to punch is used, it is ensured that mold use effect.
During use, upper die base 1 is fixed in the mechanism for pushing of forcing press, lower die base 2 is fixed on the work top of forcing press, both are correspondingly arranged up and down.During punching press; by angle steel workpiece 18 to be processed while insertion locating slot 8; positioned by positioning component; another side and the upper surface plane contact of lower die base 2; the position of 18 respective slot 7 of angle steel workpiece is bending part; start forcing press; upper die base 1 is made to drive the downward punching press of die; by in the position press-in groove 7 of 18 respective slot 7 of angle steel workpiece; during processing; height of the punch 4 relative to upper die base 1, and then the angle of change angle steel bending can be adjusted by the thickness of change adjusting pad 5, using effect is good.
4 specific method of adjustment of punch is, when little bending angle is needed, 5 thickness of adjusting pad is reduced, 1 one segment distance of upper end indentation upper die base of punch 4 is made.Conversely, adjusting pad 5 is thickened, punch 4 all exposes upper die base 1, and the angle steel workpiece 18 for now stamping out is the maximum angle that the predetermined mould can stamp out.
The invention reasonable in design, treats the angle steel work piece of bending in locating slot, and by positioning component clamping and positioning, the positioning precision of angle steel workpiece is high, it is ensured that higher yield rate, production efficiency are improved, low cost of manufacture.
It is obvious to a person skilled in the art that the invention is not limited to the details of above-mentioned one exemplary embodiment, and in the case of the spirit or essential attributes without departing substantially from the invention, the invention can be realized in other specific forms.
Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the invention is by claims rather than described above is limited, it is intended that all changes in the implication and scope of the equivalency of claim that will fall are included in the invention.Any reference in claim should not be considered as and limit involved claim.
In addition, it should be understood that, although this specification is been described by according to embodiment, but not each embodiment only includes an independent technical scheme, this narrating mode of description is only for clarity, those skilled in the art should using description as an entirety, the technical scheme in each embodiment can also Jing it is appropriately combined, formed it will be appreciated by those skilled in the art that other embodiment.
