Description
Technical Field
The utility model relates to an auto-parts field especially relates to a solve stamping die of easy fold of plate shaping.
Background
Generally, the sheet metal is wrinkled in the forming process, the flow condition of the sheet metal is controlled by increasing the coefficient of a draw bead on a ring die by a conventional solution, but the sheet metal is cracked, particularly wrinkles occur in an inner area, and the improvement of the inner wrinkles by singly adjusting the draw bead is very small. In this case, we will add some shaping to the corrugated area inside the sheet metal to suck the material, for example, add triangular ribs at the corrugated area, which can improve the corrugation of the sheet metal to some extent, but also can cause some problems, such as interference between the sheet metal and other parts after shaping is increased, and cracking of the original non-cracked surrounding shaping can be caused, so we need a method to optimize the corrugation of the sheet metal without changing the shaping of the product.
Disclosure of Invention
In order to solve the problem mentioned in the above-mentioned background art, the utility model provides a solve stamping die of the easy fold of plate shaping can improve the condition that the fold easily takes place in panel beating inner zone.
A stamping die for solving the problem that a plate is easy to wrinkle during forming comprises an upper die base and a lower die base;
the bottom of the upper die base is fixedly connected with a pressing plate;
the lower die base is positioned below the pressing plate, the top of the lower die base is fixedly connected with a first die core, the middle of the first die core is provided with a through hole, a second die core which is in up-and-down sliding fit with the through hole is arranged in the through hole, the bottom of the second die core is connected with the lower die base through a first elastic piece, the top of the lower die base is also connected with a ring die through a plurality of second elastic pieces, and the ring die is sleeved outside the first die core;
when the first elastic piece and the second elastic piece are in the initial state, the height of the top surface of the ring die is higher than that of the top surface of the second die core, and the height of the top surface of the second die core is higher than that of the top surface of the first die core.
Furthermore, the first elastic piece and the second elastic piece are both nitrogen springs.
The utility model has the advantages that:
the utility model discloses simple structure can improve the condition that the product inner zone corrugates under the figurative condition of not changing the product.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Wherein, 1 is an upper die holder, 2 is a lower die holder, 3 is a press plate, 4 is a first die core, 5 is a through hole, 6 is a second die core, 7 is a first elastic piece, 8 is a second elastic piece, 9 is a ring die, and 10 is a material piece.
Detailed Description
The present invention will be described in further detail below with reference to the accompanying drawings by way of specific embodiments.
The stamping die for solving the problem of easy wrinkling in plate forming comprises an upper die holder 1 and a lower die holder 2;
the bottom of the upper die holder 1 is fixedly connected with a pressing plate 3;
the lower die base 2 is positioned below the pressing plate 3, the top of the lower die base 2 is fixedly connected with a first die core 4, the middle part of the first die core 4 is provided with a through hole 5, a second die core 6 which is in up-and-down sliding fit with the through hole 5 is arranged in the through hole 5, the bottom of the second die core 6 is connected with the lower die base 2 through a first elastic piece 7, the top of the lower die base 2 is also connected with a ring die 9 through a plurality of second elastic pieces 8, and the ring die 9 is sleeved outside the first die core 4;
when the first elastic member 7 and the second elastic member 8 are in the initial state, the top surface of the ring mold 9 is higher than the top surface of the second mold core 6, and the top surface of the second mold core 6 is higher than the top surface of the first mold core 4. After the first elastic member 7 and the second elastic member 8 are compressed, the top surface of the second mold core 6 can be flush with the top surface of the first mold core 4, and the top surface of the ring mold 9 can be flush with the top surface of the first mold core 4. Wherein, the first elastic part 7 and the second elastic part 8 are both nitrogen springs; the size of the second die core 6 can be determined according to the deformation area of the inner area of the metal plate.
The utility model discloses when concrete implementation: the material sheet 10 is placed at the top of the ring die 9, then the pressing plate 3 is placed above the material sheet 10, the pressing plate 3 is pressed downwards under the action of external force, and in the pressing-down process, the material sheet 10 is firstly contacted with the second die core 6, so that the inner area of the material sheet 10 is pressed by the pressing plate 3 and the second die core 6 and is not easy to wrinkle and deform. Then the first elastic element 7 and the second elastic element 8 continue to compress until the material sheet 10 contacts with the first mold core 4, and the mold assembly is completed.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
