The utility model discloses a die workpiece suitable for punching a glue-containing copper foil, which comprises an upper die, a lower die arranged below the upper die, an upper die cavity arranged inside the upper die, a transverse plate fixedly mounted inside the upper die cavity of the upper die, a mounting plate arranged below the transverse plate, a punching head fixedly mounted below the mounting plate, and a lower die arranged below the punching head. The mounting plate is a U-shaped plate, a fixing bolt is arranged in the mounting plate, a long-strip-shaped hole is formed in the transverse plate, and the transverse plate is fixedly connected with the mounting plate through the fixing bolt. According to the die, the capability that the position of a punching structure is stable after adjustment is achieved, practicability is improved, and therefore the problems that an existing die is prone to sliding after the position of the punching structure is adjusted, the punching position is changed, and the number of punching structures is not convenient to increase or decrease according to needs are solved.

According to the precise terminal material strip bending forming system, a female die is arranged on a lower die plate of a terminal material strip cutting die, and a terminal material strip of a coil changing head with a rated step length and a terminal material strip of a bending die tail are correspondingly cut into a terminal material strip head and a terminal material strip tail through a left cutting positioning needle set and a right cutting positioning needle set which are arranged on the female die; a copper welding block between a left bakelite fixing block and a right bakelite fixing block of the terminal material strip welding mechanism is provided with a left welding positioning pin group and a right welding positioning pin group, and the distance between the left welding positioning pin group and the right welding positioning pin group is equal to the distance between the left cutting positioning pin group and the right cutting positioning pin group. The left cover plate and the right cover plate are correspondingly arranged on the terminal material belt at the reel changing head and the terminal material belt at the tail of the bending die in a covering manner respectively and are correspondingly arranged above the left bakelite fixing block and the right bakelite fixing block; and the head part of the welding terminal material belt and the tail part of the welding terminal material belt are formed by stamping a whole material belt from the bending forming die. According to the system, the loss ratio of the head and tail materials of each roll of terminal material belt is reduced, and the terminal material belt can be prevented from being deformed, so that the bending process is ensured to be smoothly carried out.

The utility model discloses a punch press sliding block relates to punch press spare part field, and its technical scheme main points are: including main part, the buffer cavity is seted up in main part, is equipped with a plurality of buffer sheets in buffer cavity, and buffer sheet can move in vertical direction relative to main part. In the utility model, when the falling of main part slows down, the buffer sheet exerts a downward force on the main part under the action of inertia, reduces the rebound tendency of the main part and ensures the impact force of stamping, ensures the smooth stamping process, and the elastic sheet and the elastic gasket are all made of rubber material, which reduces the noise generated by the collision between the buffer sheets and the inner wall of the buffer cavity.

This utility model discloses a hot-cutting and punching mold for plastic parts, comprising an upper mold and a lower mold that slide together in an upper and lower manner; the upper mold has multiple punches and a punch heating device for heating each punch; the lower mold is located below the upper mold and is provided with a punching die, which has punching holes that movably engage with each punch. This utility model's hot-cutting and punching mold for plastic parts is used for punching holes in plastic parts and can prevent burrs from forming in the through holes of the plastic parts.
