The drawing device comprises a lower die base, a drawing blank holder 2, a drawing part 3, a drawing female die 4, an upper die base 5, a drawing male die 6 and a groove 7.
Detailed Description
The following description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings 1-3, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the protection scope of the present invention can be defined more clearly and clearly.
A stamping device for automobile covering part dies made of materials with different thicknesses comprises a lower die holder 1, a drawing blank holder 2, a drawing part 3, a drawing female die 4, an upper die holder 5 and a drawing male die 6, wherein the drawing female die 4 is arranged below the upper die holder 5, the drawing male die 6 is arranged in the middle of the upper portion of the lower die holder 1, the drawing blank holder 2 is arranged on the outer side of the drawing male die 6, the drawing part 3 is arranged between the drawing female die 4 and the drawing male die 6, a molded surface formed by upward protrusions in the middle of the drawing male die 6 is matched with a molded surface formed by upward depressions in the middle of the drawing female die 4, a groove 7 is arranged on the outer surface of the upper portion of the drawing blank holder 2, the groove 7 is matched with protrusions on the surface of the lower portion of the drawing female die 4, the fitting effect can be guaranteed, reliable and firm clamping is formed on blanks, the length of the, The width of the lower die holder 1 is larger than the widths of the drawing female die 4 and the drawing blank holder 2, so that the upper die holder and the lower die holder can conveniently perform pressure action on the drawing female die, the drawing male die and the drawing blank holder, and the drawing piece 3 is formed by splicing and drawing three steel plates, wherein the thickness of the steel plates on two sides is 0.8mm, the thickness of the middle steel plate is 1.4mm, the middle steel plate is rectangular, the steel plates on two sides are trapezoidal, and the widths of the steel plates on two sides are gradually reduced along the direction far away from the middle steel plate.
As shown in fig. 2 and 3, among three steel plates of the blank, the thickness of the two side steel plates is 0.8mm, the thickness of the middle steel plate is 1.4mm, the middle steel plate is rectangular, the two side steel plates are trapezoidal, and the width of the two side steel plates is gradually reduced along the direction far away from the middle steel plate.
The utility model provides an automobile panel mould stamping device's of different thickness materials stamping process does: firstly, splicing three steel plates with different thicknesses and different materials into a blank by laser; then, the upper die base is lifted to the upper limit height, and the drawing female die is lifted; then placing the blank on a drawing convex die; then, descending the drawing female die to align the drawing female die with the drawing male die and the drawing blank holder to form a binding surface; and finally, the upper die base is lowered, and the upper die base, the drawing female die, the drawing blank holder and the drawing male die act together with the lower die base to press the blank and draw and form the blank.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes of the present invention are used for the transformation, or directly or indirectly applied to other related technical fields, which are all included in the same way in the patent protection scope of the present invention.
