Abstract
The utility model discloses a plate-turning demoulding mechanism for a bended plate, which comprises an upper die (1) and a lower die (2). The utility model is characterized in that a jacking strut spring (3) is longitudinally arranged inside the lower die (2), a jacking strut (4) is arranged at the upper end of the jacking strut spring (3), the jacking strut (4) is positioned below a turning insert block (5) which is hinged with the upper surface of the upper die (1), an inclined plane (9) is arranged on a side surface of the turning insert block (5), a limiting block (6) is arranged on one side of the lower die (2), which is close to the pivot point of the turning insert block (5), a support spring (7) is arranged on the lower die (2), a support column (11) is arranged on the support spring (7), a bending male die (8) is longitudinally arranged inside the upper die (1) and can move relative to the upper die (1), and the position of the bending male die (8) is matched with that of the inclined plane (9) of the turning insert block (5). The utility model has the advantages as follows: the plate-turning demoulding mechanism for the bended plate has a simple structure and a smart design, and can achieve the effect of smoothly demoulding a plate in which a side face is bended inwardly by punch-forming.
Description
Technical field
The utility model relates to a kind of mould emptier, and especially a kind of punch forming side that can be used for has aduncate mould emptier.
Background technology
Prepare in the process of workpiece in punch forming, sometimes need to process the aduncate sheet material workpiece of side as shown in Figure 1, when the sheet material of this shape carries out the demoulding, jacking block and slide block with the inclined-plane that matches need be set between upper die and lower die, therefore this version just require its intensity higher because jacking block needs frequently to contact with slide block, so just makes that the volume of jacking block and slide block is bigger, make that taking up room of whole mould emptier is bigger, and cost is higher; Simultaneously in moment that jacking block contacts with slide block, impulsive force between the two is bigger, so just may have influence on the machining accuracy of mould, therefore need carry out frequent correction and debugging to mould, not only increased workman's the amount of labour, but also reduced productive temp, especially when producing in enormous quantities, greatly influenced the normal activity of product.
Summary of the invention
The utility model is in order to solve the above-mentioned deficiency of existing in prior technology, proposes a kind of simple in structurely, designs ingeniously, can realize that the punch forming side has the crooked reprint mould emptier of the smooth demoulding of sheet material of inflexion.
Concrete solution of the present utility model is: a kind of crooked turnover panel mould emptier; comprise patrix 1 and counterdie 2; it is characterized in that: in counterdie 2, be vertically arranged with fore-set spring 3; the upper end of fore-set spring 3 is provided with fore-set 4; fore-set 4 is positioned at the upset that is hinged on counterdie 1 upper surface 5 belows of inserting; insert 5 side of upset is provided with inclined-plane 9; near upset insert 5 fulcrums, one side counterdie 1 be provided with limited block 6; on counterdie 1, also be provided with support spring 7; support spring 7 is provided with support column 11; in patrix 1, also be vertically arranged with can with the crooked punch 8 of patrix 1 relative motion, and insert 59 positions, inclined-plane of crooked punch 8 and upset match.
The utility model is compared with prior art, has following advantage:
This kind of version mould emptier; it is simple in structure; design ingenious; novel; it has broken away from the design constraint of the jacking block that is provided with the inclined-plane that matches in traditional mould emptier and slide block; creatively selected for use the upset that is hinged on the counterdie upper surface to insert; and join to withstand spring and fore-set; simultaneously hypotenuse is set in the relevant position that upset is inserted, with this abnormal shape of smooth realization, the demoulding of the aduncate sheet material of side; in punching press and knockout course, have contact with each other between each parts of the mould emptier of this version; therefore can not produce bigger impulsive force, guarantee the machining accuracy of product effectively, prolong the service life of mould.Therefore we can say that this mould emptier has possessed multiple advantage, possess extensive market prospects, very help applying in the art.

The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present utility model.As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5: a kind of crooked turnover panel mould emptier, comprise patrix 1 and counterdie 2, required stamping forming workpiece 10 is between patrix 1 and counterdie 2, in counterdie 2, be vertically arranged with fore-set spring 3, be provided with fore-set 4 in the upper end of fore-set spring 3, and on the counterdie 1 of fore-set 4 tops, then be hinged with upset and insert 5, on inserting 5 side, upset offers inclined- plane 9,5 limited blocks that match of inserting also are provided with and overturn on the counterdie 1 of 5 fulcrums, one side of inserting near upset, on counterdie 1, also be provided with support spring 7, above support spring 7, be provided with support column 11, be used for supporting workpiece 10; In patrix 1, be vertically arranged with the crooked punch 8 that relative motion can take place with patrix 1, and the insert position of 5 ramps 9 of the horizontal level of crooked punch 8 and upset matches.
When needs carried out punch forming to workpiece 10, as shown in Figure 2, fore-set spring 3 and support spring 7 all stretched, and being inserted by the upset of fore-set 4 jack-up 5 is positioned on the same horizontal plane with the peak of support column 11, makes support workpiece 10 maintenance levels thereon;
During punching press, patrix 1 moves downward under the drive of press machine, and upset 5 levels of inserting are pressed on the counterdie 2, and this moment, fore-set spring 3 and support spring 7 all were compressed, and insert 5 upper surface of the lower surface of workpiece and upset fits tightly (as shown in Figure 3);
Crooked then punch 8 moves downward, make the side generation bending of workpiece 10, because the side of workpiece 10 also is provided with an inside bending, therefore insert 5 side of upset is provided with intilted inclined-plane 9, the 9 lucky spaces that curved sides after the bending is required, inclined-plane allow out, do not influence the punch forming (as shown in Figure 4) of workpiece 10;
After punching press is finished, patrix 1 moves upward, fore-set spring 3 stretches again, make fore-set 4 drive upset and insert and 5 rotate, when upset insert 5 turn to a certain degree after, upset is inserted and 5 is contacted with limited block 6, realize the location, upset is inserted and 5 is turned to extreme position, workpiece 10 be reversed insert 5 and the same support column that rises 11 hold up, realize the purpose of the demoulding.
Same because the existence on inclined-plane 9, in the process of workpiece 10 demouldings, on the workpiece 10 inwardly the part of bending can not insert and 5 interfere workpiece 10 demoulding smoothly with upset.
