Description
Technical field
The utility model belongs to metal forming punch process field, relates to a kind of mould structure, relates in particular to the compound bending die structure of a kind of U-shaped cross section crooked part.
Background technology
Along with improving constantly of the domestic prices of raw and semifnished materials and cost of labor, the cold stamping part productive profit of enterprise is extruded always.When formulating Sheet Metal Forming Technology, have to consider to control the production cost of part.In the punch process of metallic article, while determining the press-bending operation of U-shaped cross section crooked part, traditional mould structure is to carry out respectively U-shaped and L shaped press-bending operation realizes, generally needs two molds to complete, and production efficiency is lower.Therefore, develop a kind of one operation of a mold that can adopt and complete processing mold L shaped and that U-shaped bends, for enhancing productivity, reduce the production cost important in inhibiting of part processing.
The utility model content
The purpose of this utility model is to provide the compound bending die structure of a kind of U-shaped cross section crooked part.Utilize this mould structure U-shaped can be bent and the synthetic procedure of L shaped press-bending, realize on a mold, thereby the minimizing operation, enhance productivity.
The technical solution of the utility model is: the compound bending die structure of U-shaped cross section crooked part comprises: upper bolster, guide plate, location-plate, special type screw, material returned spring, product, backing-out punch, die, movable punch, extension bar, pressure pin, inner guide plate, alignment pin, punch, die shoe.Backing-out punch is articulated on upper bolster by special type screw, and material returned spring fitting is between backing-out punch and upper bolster, and die is fixed on upper bolster; Guide plate, location-plate and punch are fixed on die shoe successively; Inner guide plate, alignment pin are fixed on movable punch, and extension bar is screwed onto on movable punch, movable punch is contained in the die shoe upper chambers.
The utility model adopts the good effect of obtaining after technique scheme to be: solved the part production process long, take the problems such as equipment and personnel are many, mould structure is simple, manufacture and easy to maintenance, in production process, Mould operation is easy, has effectively improved production efficiency.

The specific embodiment
Below the utility model is described in further detail with reference to the accompanying drawings.The compound bending die structure of U-shaped cross section crooked part mainly comprises: upper bolster 1, guide plate 2, location-plate 3, special type screw 4, material returned spring 5, product 6, backing-out punch 7, die 8, movable punch 9, extension bar 10, pressure pin 11, inner guide plate 12, alignment pin 13, punch 14, die shoe 15.Backing-out punch 7 is articulated on upper bolster 1 by special type screw 4, and material returned spring 5 is arranged between backing-out punch 7 and upper bolster 1, and backing-out punch 7 can move up and down in die 8; Die 8 is fixed on upper bolster 1, is arranged on the slide block of forcing press, forms patrix; Guide plate 2, location-plate 3 and punch 14 are fixed on die shoe 15.Inner guide plate 12, alignment pin 13 are fixed on movable punch 9, extension bar 10 is screwed onto on movable punch 9, movable punch 9 is contained in die shoe 15 chambeies, movable punch 9 can move up and down under the guiding of inner guide plate 12 in die shoe 15, and die shoe 15 is fixed on the workbench of forcing press, forms counterdie.
When opening, backing-out punch 7 be subject to gravity and under special type screw 4 effect lower than the thickness of a product 6 of die 8 lower planes; Above movable punch 9 and punch 14, be inclined-plane, pressure pin 11 is by the promotion of the cushion thrust under press bench extension bar 10, thereby movable punch 9 is pushed into to the position with the top same inclined-plane of punch 14.
During work, product to be processed 6 is placed on punch 14 and movable punch 9, and the borehole jack on product 6 is entered in the alignment pin 13 on movable punch 9, simultaneously by location-plate 3 location, press ram is descending, upper bolster 1, die 8, backing-out punch 7 is thereupon descending, die 8 first contacts with product 6, and then backing-out punch 7 also contacts with product 6, and jointly push down product 6 with movable punch 9, with the forcing press top shoe, continue descending, movable punch 9 promotes backing-out punch 7 compression material returned springs 5 and does relative upstroke, product 6 is headed in die 8, completing U-shaped bends, at the same time, it is descending that die 8 promotes movable punch 9, product 6 and punch 14 contacts area are increased gradually, product 6 first is pressed into L shaped bending by die 8 and punch 14, product 6 first is pressed into the U-shaped bending by die 8 and punch 14 subsequently, until movable punch 9 contacts with die shoe 15.After operation completes, the press top shoe is up, drive upper bolster 1, die 8, backing-out punch 7 up, the up punch 14 that is pushed out of movable punch 9 under the return force function of press air cushion, progressively return to original position, backing-out punch 7 is released die 8 to product 6 under the 5 restoring force effects of material returned spring, now can take out product 6.
In punching production, utilize the compound bending die structure of this U-shaped cross section crooked part, easy to operate, production process is few, and production efficiency is high.
