Abstract

The invention discloses an inclined hole punching die, and relates to a punching die. The inclined hole punching die comprises an upper die base, a lower die base and a die handle. A female die which is matched with a workpiece in shape is arranged on the upper surface of the lower die base, an inclined female die hole is formed in the female die, a material pressing plate is arranged above the female die, the material pressing plate is movably connected with the upper die base through a material pressing screw, the material pressing screw is connected with a material pressing rubber pad in a sleeved mode, a male die which is matched with the female die hole is arranged on the material pressing plate in an inclined mode, the male die is movably connected with the material pressing plate through a reset spring, the upper end of the male die stretches out of the upper surface of the material pressing plate, a pressing block is arranged on the lower surface of the upper die base and the lower surface of the pressing block is provided with an inclined face matched with the male die. By means of the inclined hole punching die, an inclined hole with a certain angle formed between the surface of a shell-shaped part and the horizontal direction or the vertical direction can be formed, the machining efficiency is improved and the labor intensity of workers is lowered.

Description

Punching Die of Oblique Hole
Technical field
The present invention relates to a kind of diel, relate in particular to a kind of Punching Die of Oblique Hole.
Background technology
Punching press, is at room temperature to utilize the mould being arranged on forcing press to exert pressure to material, 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 manufacture.Processing for hull shape parts list face, generally 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, on hull shape part with level or the angled inclined hole of vertical direction, can not adopt existing perforating die to be shaped, can only adopt the processing modes such as brill or milling, inefficiency, labor strength is high, very inconvenient.
Summary of the invention
The problem existing for above-mentioned prior art, the invention 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.
Technical scheme of the present invention is: a kind of Punching Die of Oblique Hole, comprise upper bolster, die shoe and die shank, die shoe upper surface is provided with the die with workpiece form fit, on die, have the die hole of inclination, die top is provided with holding pad, described holding pad is flexibly connected with upper bolster by binder screw, on binder screw, be socketed with binder rubber blanket, holding pad tilts and is provided with the punch coordinating with die hole, punch is flexibly connected with holding pad by back-moving spring, holding pad upper surface is stretched out in the upper end of punch, upper bolster lower surface is provided with briquetting, briquetting lower surface is provided with the inclined-plane coordinating with punch.
As preferably, on die, the symmetrical die hole that has two inclinations, is symmetrically arranged with two punch on holding pad, briquetting lower surface is respectively arranged with the inclined-plane coordinating with two punch, on holding pad, be provided with limiting plate, limiting plate upper surface is stretched out in punch upper end, and punch upper surface is hemisphere face.
As preferably, on die shoe, be provided with guide pillar, in holding pad, be provided with the guide pin bushing coordinating with guide pillar, guide column sleeve is connected in guide pin bushing, and guide pillar and die are all fixedly connected on die shoe upper surface by fixed head.
The invention has the beneficial effects as follows: the die hole that is provided with inclination on die of the present invention, on holding pad, be provided with the punch of the inclination coordinating with die hole, punch is flexibly connected with holding pad, add and man-hour workpiece is enclosed within to die surface, upper bolster moves down, and briquetting impels punch to move to die direction, complete the shaping of inclined hole, then on upper bolster, move, punch is got back to initial position under the effect of back-moving spring, waits for stamping-out next time.The present invention's 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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
As one embodiment of the present invention, 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 workpiece form fit, has the die hole of inclination on die 2, as preferably, die 2 lower surfaces have the blind hole being communicated with die hole, and the position of die shoe 1 correspondence has the through hole being communicated with blind hole, facilitate waste material after punching under omit in printing out.
Die 2 tops are provided with holding pad 3, described holding pad 3 is flexibly connected with upper bolster 7 by binder screw 4, on binder screw 4, be socketed with binder rubber blanket 5, holding pad 3 tilts and is provided with the punch 10 coordinating with die hole, punch 10 is flexibly connected with holding pad 3 by back-moving spring 11, 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 coordinating with punch 10.
In the present embodiment, as preferably, the symmetrical die hole that has two inclinations on die 2, on holding pad 3, be symmetrically arranged with two punch 10, briquetting 9 lower surfaces are respectively arranged with the inclined-plane coordinating with two punch 10, and two inclined holes that can once-forming hull shape piece surface symmetry are very convenient.On holding pad 3, be provided with limiting plate 6, 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.
In the present embodiment, as preferably, be provided with guide pillar 13 on die shoe 1, be provided with the guide pin bushing 12 coordinating with guide pillar 13 in holding pad 3, guide pillar 13 is socketed in guide pin bushing 12, and guide pillar 13 and die 2 are all fixedly connected on die shoe 1 upper surface by fixed head 14.Guide pillar 13 has guaranteed the kinematic accuracy of holding pad 3, has improved the quality of product.
