Abstract

The utility model discloses a punching die horizontally provided with a concave die, and relates to the punching die. The punching die comprises an upper die base, a lower die base and a die handle, wherein the lower surface of the upper die base is provided with a terrace die made of hard alloy, the upper surface of the lower die base is provided with a concave die supporting base, the concave die supporting base is perpendicularly and fixedly connected with the lower die base, the concave die is fixedly connected on the concave die supporting base, the concave die is parallel to the lower die base, a concave die hole is arranged in a position corresponding to the terrace die on the upper surface of the concave die, and a reinforcement sleeve is arranged in the concave die hole. The punching die is simple in structure, capable of machining side holes of rotary workpieces conveniently and rapidly, high in work efficiency, low in machining cost, and high in position precision of the holes.

Description

The horizontally disposed punching die of die

Technical field

The utility model relates to a kind of diel, relates in particular to the horizontally disposed punching die of a kind of die.

Background technology

In production and processing, need in the surface of the work perforate, generally be to adopt drilling machine or milling machine processing in the prior art usually, perhaps adopt the Manual drilling instrument manually to process, manually process operation person labour intensity is large, inefficiency, the positional precision of the holes of products that processes is low, and percent defective is high.If adopt the processing of drilling machine or milling machine, the positional precision in hole is high, but for the processing of jatharapanvartanasana workpiece (such as cylindrical member, box part, large-scale covering etc.) areole, adopt the processing of drilling machine or milling machine inconvenient, processing cost is high, and special in the larger side opening in aperture, working (machining) efficiency is low.

Summary of the invention

For the problem that above-mentioned prior art exists, the utility model provides a kind of die horizontally disposed punching die, and is simple in structure, can carry out easily and fast the processing of jatharapanvartanasana workpiece side opening, high efficiency, and processing cost is low, and the positional precision in hole is high.

The technical solution of the utility model is: the horizontally disposed punching die of a kind of die, comprise upper bolster, die shoe and die shank, the upper bolster lower surface is provided with punch, punch adopts carbide alloy to make, and the die shoe upper surface is provided with the die bearing, and the die bearing is fixedly connected with die shoe is vertical, be fixedly connected with die on the die bearing, die is parallel with die shoe, and the position that the die upper surface is corresponding with punch has die hole, is provided with reinforcing sleeve in the die hole.

As preferably, be provided with backing plate between punch and the upper bolster, punch is fixedly connected on the backing plate lower surface by punch retainer, and punch is socketed with stripper outward, and stripper is connected with punch retainer by the discharging spring.

As preferably, punch is up big and down small stairstepping, and die hole is up-small and down-big shoulder hole, and the die bearing is fixedly connected on the die shoe upper surface by bottom plate, and die bearing sidewall is provided with the triangle ribs.

The beneficial effects of the utility model are: the utility model is simple in structure, adds only jatharapanvartanasana workpiece to be processed to be enclosed within on the die man-hour, then the starting pressure machine, punch moves down under the drive of upper bolster, with the die interlock, finish the processing of jatharapanvartanasana workpiece side opening, very convenient, operator's labour intensity is low, high efficiency, processing cost is low, and workpiece is located by die, the positional precision in hole is high, and is very convenient and practical.

Description of drawings

Fig. 1 is structural representation of the present utility model.

The specific embodiment

As a kind of embodiment of the present utility model, as shown in Figure 1, the horizontally disposed punching die of a kind of die, comprise upper bolster 6, die shoe 1 and die shank 7, in the present embodiment, as preferably, upper bolster 6 and die shoe 1 adopt the Q235 steel plate to make good combination property, long service life.Upper bolster 6 lower surfaces are provided with punch 9, and punch 9 adopts carbide alloy to make, and hardness and intensity are high, long service life.Die shoe 1 upper surface is provided with die bearing 11, die bearing 11 and die shoe 1 vertical being fixedly connected with, be fixedly connected with die 2 on the die bearing 11, die 2 is parallel with die shoe 1, die 2 upper surfaces and punch 9 corresponding positions have die hole, be provided with reinforcing sleeve 10 in the die hole, can prolong the service life of die 2.

In the present embodiment, as preferably, be provided with backing plate 8 between punch 9 and the upper bolster 6, punch 9 is fixedly connected on backing plate 8 lower surfaces by punch retainer 5, and backing plate 8 can slow down the impact of 9 pairs of upper bolsters 6 of punch, prolongs service life of the present utility model.Be socketed with stripper 3 outside the punch 9, stripper 3 is connected with punch retainer 5 by discharging spring 4.Stripper 3 can increase the pressure of workpiece during punching press, prevents that workpiece is wrinkling, can prevent that after punching press is finished workpiece is enclosed within on the punch 9.

In the present embodiment, as preferably, punch 9 is up big and down small stairstepping, has improved the intensity of punch 9.Die hole is up-small and down-big shoulder hole, makes things convenient for the discharge of waste material.Die bearing 11 is fixedly connected on die shoe 1 upper surface by bottom plate 13, die bearing 11 sidewalls are provided with triangle ribs 12, improve the intensity of die bearing 11, avoided die bearing 11 horizontal play under the effect of punch 9, improved the precision of product.

The above only is a kind of embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and obvious mode of texturing etc., all should be included within the protection domain of the present utility model.
