Description

Technical Field

[0001] The utility model discloses a trimming die waste material discharge auxiliary device, belonging to the technical field of automobile stamping die waste material discharge. Background Art

[0002] A large amount of waste will be generated during the trimming process of the stamping die. The entire length of the waste must slide down from the die. Too much waste is not allowed to accumulate on the die. Excessive waste accumulation will affect work efficiency and cause certain troubles to factory operations. Especially for stamping parts in automated production lines, the slippage of waste is more critical. Poor scrap slippage in automated production may even cause line stoppage.

[0003] Typically, scrap material slides off by relying on the die's own height. However, due to structural limitations, some dies lack sufficient height, making it difficult for the die to meet the desired sliding angle, preventing the scrap material from sliding off. Steel coils are coated with rust-proof oil before leaving the factory, increasing resistance between the scrap material, the die casting, and the scrap slide, making it difficult to slide off. When the die lacks vertical clearance, scrap material can easily become trapped between the die's lower edge and parts of the casting during trimming, preventing it from sliding off. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the existing mold is difficult to meet the scrap sliding angle through its own structure, and because the steel coils are coated with anti-rust oil when leaving the factory, the resistance between the scrap and the mold casting and the scrap slide is increased, resulting in the inability to make the scrap slide. A trimming mold waste discharge auxiliary device is proposed.

[0005] The problem to be solved by the present invention is achieved by the following technical solutions:

[0006] A trimming die waste discharge auxiliary device includes an L-shaped positioning plate installed on the lower stamping die between the upper stamping die and the lower stamping die. A swing mechanism is fixed to the outer side of the vertical plate of the L-shaped positioning plate. The execution end of the swing mechanism is connected to the middle part of the U-shaped push handle. The U-shaped push handle can cooperate with the bottom of the waste of the stamping part.

[0007] The U-shaped fork and the T-shaped swing arm are connected to the U-shaped push-piece with a plurality of sliding sleeves at the ends of the U-shaped fork, and the T-shaped swing arm can slide along the sliding sleeve through the vertical groove provided on the vertical side. The mounting seat is provided with a cross groove, and the U-shaped fork and the T-shaped swing arm on the executing end of the discharge cylinder can slide along the cross groove respectively. The vertical side end of the T-shaped swing arm is rotatably provided with a hinge shaft, and the hinge shaft is carried on the lower half of the vertical groove of the cross groove, and the horizontal side of the T-shaped swing arm is connected to the middle part of the U-shaped push-piece.

[0008] Preferably, a gasket is provided between the exhaust cylinder and the mounting seat.

[0009] Preferably, a cover plate is provided at one end of the mounting base away from the exhaust cylinder.

[0010] The present invention has the following beneficial effects compared with the existing ones:

[0011] The utility model provides a new type of waste sliding device for stamping dies, which changes the waste discharge that relies on its own gravity into the waste discharge with the help of external force, reducing the risk of waste jamming, so that the waste can be smoothly discharged with the help of the force of the cylinder pushing outward, and there is no need to stop the machine for manual cleaning due to waste jam, thereby improving production efficiency and solving the problems of waste jamming when the waste sliding angle is small, the waste is difficult to slide down with oil, and the vertical height of the die slide is insufficient.
