Abstract
The invention discloses a kind of one-shot forming circle_curling die tool, relate to diel manufacturing technology field, include patrix and die, described die is located at the top of the intracavity sidewall of die shoe, holding pad is provided with at the lower removable of described inner chamber, described holding pad is provided with the slide rail of material returned insert and described material returned insert, and described material returned insert is connected with advance and retreat cylinder.Compared with prior art, structure of the present invention is simple, and easy to operate, with short production cycle, production efficiency is high, can effectively reduce labor intensity, and reduces production cost.
Description
Technical field
The present invention relates to diel manufacturing technology field, especially a kind of one-shot forming circle_curling die tool of the circle of the volume for loading machine side door plate.
Background technology
Loading machine side door plate is the side protective plate of the enging cabin of loading machine, is parts indispensable on loading machine, and engine can be protected to improve again the outward appearance level of loading machine; At present, the volume circle of loading machine side door plate adopts and divides three punching presses ability producing shaped by three molds, first door-plate edge is pre-bent to 1/2 circle, conveniently feeding, and periphery pre-bending adopts two cover side shaping molds; Then again with circle_curling die tool complete below 1/2 circle shaping.There is following deficiency in process of production in this production method by side door coiled sheet circle: because the shaping a whole set of operation need of work of side door plate uses three molds, divide three punching presses just can complete, manufacturing procedure is many, production efficiency is low, and the production cycle is long, and labour intensity is large, production cost is high.
Summary of the invention
The object of this invention is to provide a kind of one-shot forming circle_curling die tool, the volume circle manufacturing procedure that it can solve existing loading machine side door plate is many, and the production cycle is long, the problem that production efficiency is low.
In order to solve the problem, the technical solution used in the present invention is: this one-shot forming circle_curling die tool includes patrix and die, described die is located at the top of the intracavity sidewall of die shoe, holding pad is provided with at the lower removable of described inner chamber, described holding pad is provided with the slide rail of material returned insert and described material returned insert, and described material returned insert is connected with advance and retreat cylinder.
In the technical scheme of above-mentioned one-shot forming circle_curling die tool, technical scheme can also be more specifically: described die is provided with last volume circle shaping groove, is provided with the upper volume circle shaping groove corresponding with described last volume circle shaping groove in the side of described material returned insert.
Further, the limited block of described material returned insert is provided with at described die shoe intracavity sidewall; Back-moving spring is provided with between described die shoe intracavity bottom and described holding pad.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, due to the work that the volume of original processing loading machine side door plate circle needs three mold, three Sheet Metal Forming Technologies can just can complete by the present invention, can complete through a punching press, optimize manufacturing procedure, greatly reduce labour intensity, shorten the manufacturing cycle, reduce production cost, production efficiency is high;
2, because the present invention adopts the structural design of the material pressing device being provided with back-moving spring and the discharging device being provided with advance and retreat cylinder, production binder is stable, feeding is convenient, and maintenance of being more convenient for, performance safety is reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the partial enlarged drawing at the I place of Fig. 1.
Fig. 3 is unloading position schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
One-shot forming circle_curling die tool as shown in Figure 1, Figure 2, Figure 3 shows, include patrix 6 and die 4, die 4 is located at the top of the intracavity sidewall of die shoe 1, holding pad 3 is provided with at the lower removable of inner chamber, holding pad 3 is provided with the slide rail 7 of material returned insert 5 and this material returned insert 5, and material returned insert 5 is connected with advance and retreat cylinder 10, die 4 is provided with last volume circle shaping groove, is provided with the upper volume circle shaping groove corresponding with this last volume circle shaping groove in the side of material returned insert 5, the limited block 9 of material returned insert 5 is provided with at die shoe 1 intracavity sidewall, back-moving spring 2 is provided with between die shoe 1 intracavity bottom and holding pad 3, guiding surface is provided with between the upper surface and madial wall of die 4, the rear end of material returned insert 5 is connected with the piston rod of advance and retreat cylinder 10 by connecting plate 8, during work, patrix 6 is arranged on the upper table of hydraulic press, die shoe 1 is arranged on hydraulic press lower table, start the rising of hydraulic press upper table and open patrix 6, holding pad 3 will be installed in the material returned insert 5 on holding pad 3 under the effect of back-moving spring 2 elastic force, advance and retreat cylinder 10 floats with holding pad 3, and prevent holding pad 3 from ejecting die shoe 1 by the spacing briquetting being located at holding pad 3 upper end surrounding, now plate 13 is placed on holding pad 3, operation advance and retreat cylinder 10 is inflated and arrive binder position after the upper volume circle shaping groove forming surface in the outside of material returned insert 5 and the internal chamber wall of die 4 is offseted by front wheel driving, now start hydraulic press upper table down to move, under the effect of back-moving spring 2, holding pad 3 and patrix 6 compress side door plate 13, hydraulic press upper table continues down to move, holding pad 3, side door plate 13 down moves together along with patrix 6, side door plate 13 slowly imports in the last volume circle shaping groove of die 4 by the guiding surface between die 4 upper surface and madial wall along the internal chamber wall of die 4, now the upper table of hydraulic press still continues down to move, side door plate 13 is along the wall flow of die 4 last volume circle shaping groove, when the contact 12 of holding pad 3 bottom contacts with the boss 11 of the corresponding setting in die shoe 1 die cavity bottom surface, patrix 6 and die shoe 1 matched moulds are on earth, shape after the shape at volume circle place of side door plate 13 combines with the upper volume circle shaping groove outside the last volume circle shaping groove of die 4 and material returned insert 5 is the same, side door plate 13 volume has been justified, now hydraulic press upper table starts up to move, patrix 6 is opened, holding pad 3 up floats under the effect of back-moving spring 2 elastic force, material returned insert 5 level under the retraction of advance and retreat cylinder 10 piston rod drives returns to the position of limited block 9, now side door plate 13 is taken out, whole stamping period completes.
