Technical Field

[0001] This utility model relates to the field of automotive stamping die technology, specifically a stamping die suitable for automotive side panels. Background Technology

[0002] The side panels of automobiles need to be stamped using stamping dies, which have at least a punch and a die with the same shape as the product, and then formed by mold closing.

[0003] Existing stamping dies for automobile side panels, such as patent document CN201721039467.2 entitled "A Stamping Die for Automobile Side Panels," require the replacement of corresponding punches and dies when processing automobile side panels of different shapes. Due to the large area of ​​automobile side panels, the area and weight of punches and dies are also large, so cranes are often needed for lifting during replacement.

[0004] However, the threaded holes need to be aligned during hoisting before installation, which is often difficult for a single person to operate. This results in the problem of time-consuming and laborious alignment of the threaded holes, thus increasing labor intensity and safety hazards. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] See Figures 1-4 This utility model provides the following two technical solutions: First embodiment: A stamping die suitable for automobile side panels includes a fixed platform 1 and an adjusting assembly. The fixed platform 1 is equipped with a bracket 2 and a support plate 3. The support plate 3 is equipped with a top plate 4, and a die cavity 5 is attached to the top plate 4. Bolts 6 connecting to the support plate 3 are provided around the die cavity 5 to fix it in place. A die cavity 7 matching the shape of the automobile side panel is provided on the die cavity 5. Hydraulic telescopic rods 8 are provided around the fixed platform 1, and all four hydraulic telescopic rods 8 are connected to a support frame 9. Used to drive the support frame 9 to lift and lower, so as to drive the punch 12 to close or open the mold. A flow distributor is used to evenly distribute the hydraulic oil flow to each hydraulic telescopic rod 8 to ensure that each cylinder receives the same flow, thereby achieving synchronization. A punch seat 10 is attached to the support frame 9. Bolts 11 connected to the support frame 9 are provided around the punch seat 10. A punch 12 matching the shape of the car side panel is provided on the punch seat 10. Lifting rings 13 are provided around the punch seat 10 and the die seat 5 for connecting the lifting rope. The fixed platform 1 has through slots 14 on all four sides. The inner wall of the through slots 14 is fitted with positioning plates 15. The adjustment component is used to adjust the position of the positioning plates 15 on all four sides. When the die holder 5 and the punch holder 10 are lowered, they are positioned by the positioning plates 15 on all four sides. Then, they can be lowered directly along the positioning plates 15 on all four sides to align the threaded holes for installation. During the hoisting process, only one worker is needed to move the suspended die 7 or punch 12, which saves manpower and is more efficient. It is especially suitable for stamping dies for automobile side panels that often need to be replaced with die 7 and punch 12.

[0018] The adjustment assembly includes a base 16, on which an electric push rod 17 is mounted. The output end of the electric push rod 17 is connected to a mounting rod 18. The electric push rod 17 is used to adjust the height of the positioning plate 15. Electric telescopic rods 19 are provided around the mounting rod 18. The electric telescopic rods 19 around the positioning plates 15 are connected to the positioning plates 15 around the positioning plates 15 by mounting structures. The electric telescopic rods 19 are used to adjust the horizontal position of the positioning plates 15.

[0019] The mounting structure includes a mounting groove 20 on the electric telescopic rod 19, and a positioning plate 15 is fitted into the mounting groove 20. The mounting groove 20 is provided with several screw holes 21, and two of the screw holes 21 are provided with bolts 22 that are connected to the positioning plate 15. When the positioning plate 15 is flipped over, the bolts 22 can be connected to the other two screw holes 21, so that both sides of the positioning plate 15 can be used. Furthermore, when one side of the positioning plate 15 is severely worn, the other side can be used for positioning, thereby improving the service life of the positioning plate 15.

[0020] The base 16 is provided with a vertical rod 23 that passes through the mounting rod 18 to guide the mounting rod 18. The vertical rod 23 is also provided with a support block 24 that contacts the bottom of the mounting rod 18, which can support the mounting rod 18 when the positioning plate 15 is not in use, thereby reducing the force on the electric push rod 17.

[0021] The cross-sectional areas of punch 12, die holder 5 and die 7 are all smaller than the cross-sectional area inside the support frame 9, ensuring that punch 12, die holder 5 and die 7 can all pass vertically through the support frame 9.

[0022] The second implementation differs from the first implementation in that: a controller 25 is provided on the fixed platform 1 to control other electrical structures, and guide rods 26 penetrating the support frame 9 are provided around the fixed platform 1 to guide the lifting and lowering of the support frame 9, so as to make the mold closing and opening more stable.

[0023] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0024] In use, position the left and rear positioning plates 15 as needed, then manually move the lifted die holder 5 to contact the left and rear positioning plates 15. Then position the right and front positioning plates 15 as needed, so that the die holder 5 is positioned by the positioning plates 15 on all sides. Continue to lift the die holder 5 from below until it contacts the top plate 4. Finally, install the bolt 6. Similarly, install the punch holder 10 on the support frame 9, and you can quickly replace the corresponding die 7 and punch 12.
