Description

One kind stretching punching Integral die
Technical field
The present invention relates to a kind of punching die, and in particular to one kind stretching punching Integral die.
Background technology
Articles made of aluminium alloy is the equipment part commonly used in industry, is required according to the shape facility of product, dimensional accuracy etc., is The influence of stretcher strain device to hole dimensional accuracy is prevented, product forming process must be punching after first stretching.Limited by machine tool System, the manufacturing procedure of existing product method is first to use a set of drawing die, then with another set of punching die in bent axle pressure Punching on machine.Existing product method uses drawing, the single die forming mode of punching, the product dimensional accuracy processed Low, required number of molds is more, and the manufacturing cost of mould is high, and the equipment that product processing takes is more, low production efficiency.Also can be using drawing Punching hole composite die is stretched, but existing composite mould structure is complicated, and applicability is poor.
The content of the invention
The technical problems to be solved by the invention are that providing one kind stretches punching Integral die, and its energy one-off hole-piercing is complete Into precision is high, and production efficiency is high, and cost is low, while the advantage of pitch of holes can be adjusted according to the actual requirements.
The technical problems to be solved by the invention are realized using following technical scheme:
One kind stretching punching Integral die, it includes upper bolster, die shoe, is arranged on by column below upper bolster Cavity plate, is arranged in the punch-pin on die shoe, described cavity plate and is provided with briquetting, described briquetting is fixed on by spring On die holder, the two ends of described upper bolster are provided with Tapered Column, and described die shoe is provided with a pair of punch mechanisms, described punching Mechanism is by U-shaped plate, punch-head assembly and punch-head assembly fixed seat composition, and the lower end of described punch-head assembly fixed seat is slided by sliding block Groove coordinates with U-shaped plate, and the two ends of the upper end of punch-head assembly fixed seat and U-shaped plate constitute the wedge-shaped slot corresponding with Tapered Column.
Described U-shaped plate two ends are respectively equipped with the spring reverse motion being connected with punch-head assembly fixed seat.
Engagement plate is additionally provided between described punch mechanism and die shoe, described engagement plate lower surface is provided with gear ring, Die shoe upper surface is provided with the gear ring I, described gear ring I being meshed with gear ring and is marked with scale.
Described punch-pin is stepped cylindrical, and passes through U-shaped plate and engagement plate.
The beneficial effects of the invention are as follows:The hole precision of perforating die processing in the present invention is high, one time punching molded, work effect Rate is high, easy to process, and pitch of holes can be adjusted according to actual conditions, and applied widely, cost is low.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention 1;
Fig. 2 is the structural representation of the embodiment of the present invention 2.
Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, tie below Conjunction is specifically illustrating, and the present invention is expanded on further.
Embodiment 1
As shown in figure 1, a kind of stretching punching Integral die, it includes upper bolster 1, die shoe 2, is arranged on by column The cavity plate 3 of the lower section of upper bolster 1, is arranged in the punch-pin 4 on die shoe 2, described cavity plate 3 and is provided with briquetting 5, described pressing Block 5 is fixed on upper bolster 1 by spring, and the two ends of described upper bolster 1 are provided with Tapered Column 6, and described die shoe 2 is provided with A pair of punch mechanisms, described punch mechanism is made up of U-shaped plate 7, punch-head assembly 8 and punch-head assembly fixed seat 9, described drift The lower end of component fixed seat 9 is coordinated by sliding block chute with U-shaped plate 7, the two ends of the upper end of punch-head assembly fixed seat 9 and U-shaped plate 7 The composition wedge-shaped slot 10 corresponding with Tapered Column 6.
The described two ends of U-shaped plate 7 are respectively equipped with the spring reverse motion 11 being connected with punch-head assembly fixed seat 9.
Embodiment 2
As shown in Fig. 2 except with addition to the identical point of above example 1, rank is additionally provided between described punch mechanism and die shoe 2 Fishplate bar 12, the described lower surface of engagement plate 12 is provided with gear ring, and the upper surface of die shoe 2 is provided with the gear being meshed with gear ring Ring I, described gear ring I are marked with scale.
Described punch-pin 4 is stepped cylindrical, and passes through U-shaped plate 7 and engagement plate 12.
Upper bolster 1 drives cavity plate 3 and briquetting 5 to move downward, and contacts, continues traveling downwardly with stamping parts 13, the two ends of upper bolster 1 Tapered Column 6 enter in wedge-shaped slot 10, extruding punch-head assembly fixed seat 9, cavity plate 3 in the process, briquetting 5 and punch-pin 4 are matched somebody with somebody Close and complete extensional motion, punch-head assembly 8 continues to move to the direction of punch-pin 4, until completing punching campaign;Upper bolster 1 is up, drift Component fixed seat 9 returns to home position in the presence of spring reverse motion 11.Engagement plate 12 is rotated to can adjust on stamping parts 13 Spacing between the position of punching and punching, convenient and swift, applicability is wide.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The technology of the industry Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the simply explanation described in above-described embodiment and specification is originally The principle of invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its Equivalent thereof.
