Abstract
The invention provides a crane bent plate press forming mold structure, which has the advantages of effectively solving the problem of frequent repair of a mold caused by unbalanced stress during press forming and prolonging the service life of the mold. The crane bent plate press forming mold structure comprises an upper die and a lower die, wherein the lower die is arranged on a substrate; the substrate is arranged on a pedestal; the lower die consists of two parts, of which one part is a bottom jacking plate having an unloading effect and the other part is a conical part formed by a side wall of a workpiece; the jacking plate is connected with a guide column; the guide column penetrates through the substrate and the pedestal; the upper surface of the jacking plate is provided with a settling tank; after an ejector rod is buckled on the settling tank, the lower part of the ejector rod extends out of the substrate and the pedestal; and four ejector rods are symmetrically arranged on the jacking plate in all.
Description
Technical field
The present invention relates to the crane bent plate and press shape part structure, be specially a kind of crane bent plate pressure-shaped mould structure.
Background technology
Making crane bent plate part often need be to the sheet material of definite shape through the compression moulding of a kind of distortion die apparatus, and the die apparatus of employing is to utilize one top, hydraulic press center at present, and guide pillar ejects; But because workpiece is asymmetric, workpiece geometric center and mould molding center do not overlap discontinuity equalization; Be prone to cause the guide pillar frequent breakage, the mold repair cycle is short, has influenced enterprise production greatly; Improve maintenance cost, reduced the service life of mould.
Summary of the invention
To the problems referred to above, the invention provides a kind of crane bent plate pressure-shaped mould structure, can effectively prevent the frequent problem of keeping in repair of the mould that in pressing the shape process, causes because of discontinuity equalization, prolong the service life of mould.
Its technical scheme is such: it comprises upper die and lower die, and said counterdie is installed on substrate, and said substrate is installed on base; Said counterdie is made up of two parts, the bottom top pressing board of a part for having held concurrently the discharging effect, and another part is the tapering part of workpiece sidewall moulding; Said top pressing board connects guide pillar; Said guide pillar passes said substrate and said base, and said top pressing board upper surface is provided with subsider, and the knock-pin spiral-lock is stretched out from said substrate and said base under behind the said subsider; It is characterized in that: totally four of said knock-pins are symmetrically arranged in said top pressing board.
The invention has the beneficial effects as follows, knock-pin is set is evenly arranged on the top pressing board, when pressing shape; Upper mould contact workpiece and descending, top pressing board are under the effect of workpiece and substrate contacts, and patrix continues to press down; Up to component shaping, during discharging, top pressing board is producing balanced forces under the knock-pin effect; Also significantly reduce the damage frequency of knock-pin and top pressing board when guaranteeing the smooth demoulding of workpiece, reduced maintenance cost, prolonged the service life of mould.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the cutaway view of Fig. 1.
The specific embodiment
Like Fig. 1, shown in Figure 2, the present invention includes patrix 1, counterdie 2, counterdie 2 is installed on substrate 3; Substrate 3 is installed on base 4, and counterdie 2 is made up of two parts, the bottom top pressing board 5 of a part for having held concurrently the discharging effect; Another part is the tapering part of workpiece sidewall moulding, and top pressing board 5 connects guide pillar 6, and guide pillar 6 passes substrate 3 and base 4; Top pressing board 5 upper surfaces are provided with subsider 7; Knock-pin 8 spiral-locks are stretched out from substrate 3 and base 4 under subsider 7 backs, and totally four of knock-pins 8 are symmetrically arranged in top pressing board 5; When pressing shape, patrix 1 contact workpiece is also descending, and top pressing board 5 contacts with substrate 3 under the effect of workpiece; Patrix 1 continues to press down, up to component shaping, during discharging; Top pressing board 5 is producing balanced forces under knock-pin 8 effects; Also significantly reduce the damage frequency of knock-pin 8 and top pressing board 5 when having guaranteed the smooth demoulding of workpiece, reduced maintenance cost, prolonged the service life of mould.
