Abstract
The utility model discloses an automobile die movable blank holder. When a pressing machine moves downwards, an upper movable blank holder (2) and a lower movable blank holder (3) move outwards to finish prestretching of a sheet (9) before a male die (8) makes contact with the sheet (9); the pressing machine continues moving downwards, and in the process of stretching of the male die (8), the upper movable blank holder (2) and the lower movable blank holder (3) contract inwards to finish feeding compensation motion, ensure that the sheet (9) deforms more evenly and more sufficiently, and ensure that the defects that a stamping part deforms, has a slip line and is lack of rigidity are well overcome.
Description
Technical field
The utility model belongs to pressure technological equipment for making field, relates in particular to the movable blank holder of a kind of automobile die.
Background technology
Top cover in the automobile body covering piece, send out parts such as cover inner and outer plates because of simple shape, the area of plane greatly, sheet metal deformation is insufficient etc., and factor causes defectives such as stamping parts distortion, skid wire, insufficient rigidity, perplexing the lifting of body quality for a long time, stock utilization is ranging in low level always simultaneously.
The utility model content
In punching course, cause defectives such as stamping parts distortion, skid wire, insufficient rigidity at traditional diel, the control panel materials flow was moving when technical problem to be solved in the utility model provided a kind of drawing, make sheet metal deformation more evenly, more abundant, make the movable blank holder of automobile die that defectives such as stamping parts distortion, skid wire, insufficient rigidity are solved well.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: the movable blank holder of a kind of automobile die, comprise upper bolster and die shoe, described die shoe is provided with fixedly blank holder moving up and down, be connected with guide rail base on the described die shoe, described fixedly blank holder is provided with down movable blank holder, described movable blank holder down can slide at described fixedly blank holder, described movable blank holder down is provided with guide rod, described guide rail base is provided with the guide rail suitable with described guide rod, and described guide rail is arc; Described upper bolster is provided with the last movable blank holder suitable with described movable blank holder down, and described movable blank holder can slide at described upper bolster.
Described upper bolster is provided with die, and described die shoe is provided with punch.
The distance of die is arrived at described guide rail middle part greater than the guide rail two ends to the distance of die.
Described movable blank holder is provided with projection, and described movable blank holder down is provided with the groove suitable with described projection.
Described die shoe is provided with through hole, and push rod passes described through hole and is connected with fixing blank holder.
Advantage of the present utility model is, by taking full advantage of the material deformation rule, and the control that plate flows during to drawing, make sheet metal deformation more evenly, more abundant, make defectives such as stamping parts distortion, skid wire, insufficient rigidity wait until well and solve.The movable blank holder of automobile die draw function in advance when realizing reducing the plate size, can under the requirement of satisfying same stiffness, reduce sheet metal thickness, comprehensively promote the material economy, have higher economical efficiency.

The specific embodiment
Fig. 1 and Fig. 2 are the structural representation of the movable blank holder of a kind of automobile die of the utility model, comprise upper bolster 1 and die shoe 6, die shoe 6 is provided with fixedly blank holder 4 moving up and down, be connected with guide rail base 7 on the die shoe 6, fixedly blank holder 4 is provided with down movable blank holder 3, and following movable blank holder 3 can be in fixedly blank holder 4 slips, and following movable blank holder 3 is provided with guide rod 31, guide rail base 7 is provided with the guide rail 71 suitable with guide rod 31, and guide rail 71 is arc; Upper bolster 1 is provided with the last movable blank holder 2 suitable with following movable blank holder 3, and going up movable blank holder 2 can be in upper bolster 1 slip.
The movable blank holder of this automobile die, have four groups be arranged on respectively mould around, go up movable blank holder 2 and be installed in above the upper bolster 1, can be driven by down movable blank holder 3 when going up movable blank holder 2 and move up and down with upper bolster 1 and do horizontal movement; Down movable blank holder 3 is installed in fixedly above the blank holder 4, can be retrained by guide rail base 7 when fixedly blank holder 4 moves up and down and move along guide rail 71; Fixedly blank holder 4 is installed in above the die shoe 6, push rod 5 and on move up and down under movable blank holder 2 common the drivings; Guide rail base 7 is fixed on above the die shoe 6, and punch 8 is fixed on the die shoe 6, and die 10 is fixed on the upper bolster 1.
Fig. 3 is the impulse stroke figure of the movable blank holder of a kind of automobile die of the utility model, and upper bolster 1 is installed on the slide block of press, and die shoe 6 is installed on the backing plate of press, and push rod 5 is by design arrangement.When upper bolster 1 drives when going up movable blank holder 2 and moving downward the down movable blank holder 3 of contact, movable blank holder 2 and following movable blank holder 3 are locked all around plate 9 utilizations in.When last movable blank holder 2 drives down movable blank holder 3 when descending, following movable blank holder 3 is done curvilinear motion at the constraint lower edge of guide rail base 7 guide rail 71, its horizontal motion components with plate 9 to around draw.When being drawn into maximum, die 10 begins to contact plate 9.Upper bolster 1 continues to move downward, plate 9 contacts with punch 8, begins the work of drawing, and movable blank holder 2 and following movable blank holder 3 are along guide rail 71 curvilinear motions on this moment, the inside feeding of its horizontal component compensates drawing, and finishes to finish drawing operation to the press stroke.
After adopting such structure, by taking full advantage of the material deformation rule, and the control that plate 9 flows during to drawing, make plate 9 distortion more evenly, more abundant, make defectives such as stamping parts distortion, skid wire, insufficient rigidity wait until well and solve.The movable blank holder of automobile die draw function in advance when realizing reducing plate 9 sizes, can under the requirement of satisfying same stiffness, reduce sheet metal thickness, comprehensively promote the material economy, have higher economical efficiency.
By reference to the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
