Abstract
The invention discloses a rolling die formed in one step, and relates to the technical field of stamping die manufacturing. The rolling die comprises an upper die body and a female die body, the female die body is arranged at the top of the side wall of an inner cavity of a lower die base, a material pressing plate is movably arranged on the lower portion of the inner cavity, a material returning insert and a sliding rail of the material returning insert are arranged on the material pressing plate, and the material returning insert is connected with an advancing and retreating air cylinder. Compared with the prior art, the rolling die formed in one step is simple in structure, convenient to operate, short in production cycle and high in production efficiency, and can effectively relieve the labor intensity and lower the production cost.
Description
Technical field
The present invention relates to diel manufacturing technology field, especially a kind of one-shot forming volume circle mould 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, can protect engine can improve again the outward appearance level of loading machine; At present, the volume of loading machine side door plate circle adopts by three molds and divides three punching presses ability production moulding, first door-plate edge is pre-bent to 1/2 circle, and in order to facilitate feeding, periphery pre-bending adopts two cover side shaping molds to complete; Then with volume circle mould, complete 1/2 circle moulding below again.There is in process of production following deficiency in this production method by side door coiled sheet circle: because a whole set of operation need of work of side door plate moulding 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 volume circle mould, 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 address the above problem, the technical solution used in the present invention is: this one-shot forming volume circle mould includes patrix and die, described die is located at the top of the intracavity sidewall of die shoe, bottom at described inner chamber is movably equipped with holding pad, on described holding pad, be provided with the slide rail that the material returned is inserted and the described material returned is inserted, the described material returned is inserted and is connected with advance and retreat cylinder.
In the technical scheme of above-mentioned one-shot forming volume circle mould, technical scheme can also be more specifically: described die is provided with last volume circle shaping groove, and a side of inserting in the described material returned is provided with the upper volume circle shaping groove corresponding with described last volume circle shaping groove.
Further, at described die shoe intracavity sidewall, be provided with the limited block that the described material returned is inserted; Between described die shoe intracavity bottom and described holding pad, be provided with back-moving spring.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:
The work that 1, the volume circle of original processing loading machine side door plate can be needed three molds, three Sheet Metal Forming Technologies just can complete due to the present invention, can complete through a punching press, has optimized manufacturing procedure, greatly reduce labour intensity, shortened the manufacturing cycle, reduced production cost, production efficiency is high;
2, because the present invention adopts the structural design that is provided with the material pressing device of back-moving spring and is provided with the discharging device of advance and retreat cylinder, production binder is stable, feeding is convenient, the maintenance of being more convenient for, and 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 discharging position view of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
One-shot forming volume circle mould 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, in the bottom of inner chamber, be movably equipped with holding pad 3, on holding pad 3, be provided with the material returned and insert 5 and this material returned slide rail 7 of 5 of inserting, the material returned is inserted and 5 is connected with advance and retreat cylinder 10, die 4 is provided with last volume circle shaping groove, in an insert side of 5 of the material returned, is provided with the upper volume circle shaping groove corresponding with this last volume circle shaping groove, at die shoe 1 intracavity sidewall, be provided with the material returned 5 the limited block 9 of inserting, between die shoe 1 intracavity bottom and holding pad 3, be provided with back-moving spring 2, between the upper surface of die 4 and madial wall, be provided with guiding surface, insert 5 rear end of the material returned 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 inserts 5 by the material returned being installed on holding pad 3 under back-moving spring 2 elastic force effects, advance and retreat cylinder 10 floats with holding pad 3, and prevent that by being located at the spacing briquetting of holding pad 3 upper end surroundings holding pad 3 from ejecting die shoe 1, now plate 13 is placed on holding pad 3, 10 inflations of operation advance and retreat cylinder are inserted the material returned after internal chamber wall that the upper volume in 5 outside justifies shaping groove forming surface and die 4 offsets and are arrived binder position toward front wheel driving, now starting hydraulic press upper table down moves, 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 motion, holding pad 3, side door plate 13 is along with patrix 6 together down motion, by the guiding surface between die 4 upper surfaces and madial wall, the internal chamber wall along die 4 slowly imports in the last volume circle shaping groove of die 4 side door plate 13, now the upper table of hydraulic press still continues down to move, side door plate 13 flows along the sidewall of die 4 last volume circle shaping grooves, when the contact 12 of holding pad 3 bottoms and the boss 11 of the die shoe 1 corresponding setting in die cavity bottom surface contact, patrix 6 and die shoe 1 matched moulds are on earth, the shape at volume circle place of side door the plate 13 and last volume of die 4 circle shaping groove and the material returned upper volume circle shaping groove in the 5 outsides shape after combining of inserting is the same, side door plate 13 volume circles complete, now hydraulic press upper table starts up to move, patrix 6 is opened, holding pad 3 up floats under back-moving spring 2 elastic force effects, the material returned insert 5 retractions at advance and retreat cylinder 10 piston rods drive under level return to the position of limited block 9, now side door plate 13 is taken out, whole stamping period completes.
