Abstract

The utility model discloses an inclined hole punching die, and relates to a punching mold. The inclined hole punching die comprises an upper die seat, a lower die seat and a die handle. The upper surface of the lower die seat is provided with a concave die matched with a workpiece in shape, and a concave die hole is formed in the concave die in an inclined mode. A pressing plate is arranged on the concave die and movably connected with the upper die seat through pressing screws, and the pressing screws are connected with a pressing rubber pad in a sleeved mode. A protruding die matched with the concave die hole is arranged on the pressing plate in an inclined mode, and the protruding die is movably connected with the pressing plate through a reset spring. The upper end of the protruding die extends out of the upper surface of the pressing plate, and the lower surface of the upper die seat is provided with a pressing block. The lower surface of the pressing block is provided with an inclined face matched with the protruding die. According to the inclined hole punching die, inclined holes in the surfaces of shell-shaped elements which are inclined to the horizontal direction or the vertical direction in a certain angle can be formed, machining efficiency is improved, and labor intensity of workers is reduced.

Description

Punching Die of Oblique Hole
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of Punching Die of Oblique Hole.
Background technology
Punching press is at room temperature to utilize the mould that is installed on the forcing press that material is exerted pressure, and makes it produce separation or plastic deformation, thereby obtains a kind of pressure processing method of required part.Diel is the requisite technological equipment of punching production, is technology-intensive product, and it can carry out the processing and forming such as punching, blanking, bending and pull and stretch.The quality of stamping parts, production efficiency and production cost etc. have direct relation with Design of Dies and manufacturing.Processing for hull shape parts list face, generally be to adopt perforating die, comprise cantilever type punching die and wedge perforating die, but existing perforating die can only along continuous straight runs or vertical direction shaped hole, and the inclined hole for angled with level or vertical direction on the hull shape part can not adopt existing perforating die to be shaped, can only adopt and bore or the processing mode such as mill, inefficiency, labor strength is high, and is very inconvenient.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of Punching Die of Oblique Hole, and the angled inclined hole of hull shape piece surface and level or vertical direction that can be shaped has improved working (machining) efficiency, has reduced labor strength.
The technical solution of the utility model is: a kind of Punching Die of Oblique Hole, comprise upper bolster, die shoe and die shank, the die shoe upper surface is provided with the die with the workpiece form fit, have the die hole of inclination on the die, the die top is provided with holding pad, described holding pad is flexibly connected by binder screw and upper bolster, be socketed with the binder rubber blanket on the binder screw, holding pad tilts and is provided with the punch that cooperates with die hole, punch is flexibly connected by back-moving spring and holding pad, the holding pad upper surface is stretched out in the upper end of punch, and the upper bolster lower surface is provided with briquetting, and the briquetting lower surface is provided with the inclined-plane that cooperates with punch.
As preferably, the symmetrical die hole that has two inclinations is symmetrically arranged with two punch on the die on the holding pad, the briquetting lower surface is respectively arranged with the inclined-plane that cooperates with two punch, be provided with limiting plate on the holding pad, the limiting plate upper surface is stretched out in the punch upper end, and the punch upper surface is hemisphere face.
As preferably, be provided with guide pillar on the die shoe, be provided with the guide pin bushing that cooperates with guide pillar in the holding pad, guide column sleeve is connected in the guide pin bushing, and guide pillar and die all are fixedly connected on the die shoe upper surface by fixed head.
The beneficial effects of the utility model are: the die hole that is provided with inclination on the utility model die, be provided with the punch of the inclination that cooperates with die hole on the holding pad, punch and holding pad are flexibly connected, add and man-hour workpiece is enclosed within the die surface, upper bolster moves down, and briquetting impels punch to move to the die direction, finish the shaping of inclined hole, then move on the upper bolster, punch is got back to initial position under the effect of back-moving spring, waits for next time stamping-out.The utility model angled inclined hole of hull shape piece surface and level or vertical direction that can be shaped, improved working (machining) efficiency, reduced labor strength, by increasing the quantity of die hole and punch, a plurality of inclined holes that can once-forming hull shape piece surface, 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, a kind of Punching Die of Oblique Hole, comprise upper bolster 7, die shoe 1 and die shank 8, die shoe 1 upper surface is provided with the die 2 with the workpiece form fit, has the die hole of inclination on the die 2, as preferably, die 2 lower surfaces have the blind hole that is communicated with die hole, and the position of die shoe 1 correspondence has the through hole that is communicated with blind hole, make things convenient for punching after the lower of waste material omit in printing out.
Die 2 tops are provided with holding pad 3, described holding pad 3 is flexibly connected by binder screw 4 and upper bolster 7, be socketed with binder rubber blanket 5 on the binder screw 4, holding pad 3 tilts and is provided with the punch 10 that cooperates with die hole, punch 10 is flexibly connected by back-moving spring 11 and holding pad 3, holding pad 3 upper surfaces are stretched out in the upper end of punch 10, and upper bolster 7 lower surfaces are provided with briquetting 9, and briquetting 9 lower surfaces are provided with the inclined-plane that cooperates with punch 10.
In the present embodiment, as preferably, the symmetrical die hole that has two inclinations on the die 2, be symmetrically arranged with two punch 10 on the holding pad 3, briquetting 9 lower surfaces are respectively arranged with the inclined-plane that cooperates with two punch 10, and two inclined holes that can once-forming hull shape piece surface symmetry are very convenient.Be provided with limiting plate 6 on the holding pad 3, limiting plate 6 upper surfaces are stretched out in punch 10 upper ends, and limiting plate 6 can prevent that punch 10 from deviating from from holding pad 3, and in the present embodiment, limiting plate 6 is connected by screw in holding pad 3 upper surfaces.Punch 10 upper surfaces are hemisphere face, have reduced the wearing and tearing of briquetting 9.
