Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
Present embodiments provide for a kind of composite die of L-type oil tight skeleton, as shown in Fig. 1 ~ 4, a cavity 13 is positioned at primarily of the punch press air cushion 5(punch press air cushion 5 below patrix (not shown), counterdie and counterdie) composition, patrix is positioned at above counterdie, the upper male mould 10 of patrix is fixed on cope match-plate pattern 11, cope match-plate pattern 11 is fixed on upper bolster 9, and the lower cavity die 6 of counterdie is fixed on lower bolster 8, and lower bolster 8 is fixed on die shoe 7; The below of lower cavity die 6 is provided with mold jacking block 1, the top surface shape of this mold jacking block 1 and the bottom shape of lower cavity die 6 cooperatively interact, push rod 2 is provided with below mold jacking block 1, the bottom surface of push rod 2 is pressed in airfilled ring 3 end face, this airfilled ring 3 is fixed on die shoe 7, arbitrarily can change according to the structure of die shoe 7, and airfilled ring pressure 3 is above air cushion cylinder 4, the top of air cushion cylinder 4 is positioned at die shoe 7, and the bottom of air cushion cylinder 4 effectively contacts with the top of punch press air cushion 5 through after cavity 13 end face; Conveniently reclaim the waste material after punching, waste recovery skewed slot 12 is also provided with in this composite die, the higher-end of this waste recovery skewed slot 12 is positioned at the intermediate throughholes of punch press air cushion 5, and below the intermediate throughholes being positioned at air cushion cylinder 4, and comparatively to reach punch press air cushion 6 outside for low side.
Figure 1 shows that punch press air cushion 5 is in die opening state, the state namely before punching press, Figure 2 shows that punch press air cushion 5 is in mold closing state, the state namely during punching press.For the ease of understanding, below in conjunction with this composite die of accompanying drawing detailed description employing, raw material are carried out to the whole process of punching press.
In die opening state, as Fig. 1 and 3, now punch press air cushion 5 opens (not compressed) completely, and the end face of mold jacking block 1 effectively contacts with the bottom surface of lower cavity die 6, and the top of punch press air cushion 5 effectively contacts with the end face of cavity 13; When needs carry out punching press to raw material 14, first raw material 14 to be punched are put on the surface of upper male mould 10, then patrix starts to move down and carries out punching press to raw material, namely the punching course to raw material 14 is started after upper male mould 10 touches raw material 14, now enter mold closing state, as Fig. 2 and 4, in punching course, due to pressing down of patrix, mold jacking block 1 is pressed down predeterminable range H by raw material 14, mold jacking block 1 moves down, and causes that push rod 2 moves down, airfilled ring 3 moves down, air cushion cylinder 4 moves down, and then compressing punch press air cushion 5 compresses H; Namely the blanking to raw material 14, stretching and punching technology is completed in above-mentioned punching course, after punching press completes, patrix rises, namely raw material 14 are stamped and form finished product or semi-finished product, the waste material formed in punch process falls to waste recovery skewed slot 12 through airfilled ring 3 intermediate throughholes, air cushion cylinder 4 intermediate throughholes and punch press air cushion 5 intermediate throughholes, derive recovery by waste recovery skewed slot 12, finished product or semi-finished product transfer to subsequent processing by raw material conveyer.
Composite die in visible use the present invention can not only realize the disposable automation of blanking, stretching and punching technology to L-type oil tight skeleton and complete, and without the need to using nitrogen cylinder to realize drawing process, punch press air cushion 5 is used to replace the nitrogen cylinder nose bar cun that can liquidate to control effectively, ensure that the size of final finished is accurate, improving product qualification rate.
Above-mentioned embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalent transformations of doing according to Spirit Essence of the present invention or modification, all should be encompassed within protection scope of the present invention.
