Problems solved by technology
[0003] However, after the existing hot forging dies forge the metal workpiece, along with the extrusion of the mold, the heated metal workpiece will adhere to the mold, and after the mold moves up, the metal workpiece is driven to move for a certain distance. It is easy to fall off, because the metal workpiece is in a high temperature state, it will cause harm to the workers, the workpiece needs to be limited, and the existing device needs manual operation when returning the material, and the material cannot be automatically returned during use, which reduces the production efficiency , is also less safe

The invention discloses a blind hole punching and hot forging device facilitating separation of a punch and a hot forging piece. The blind hole punching and hot forging device comprises a base, the top of the base is in bolted connection with a lower die, the top of the base is fixedly connected to a supporting column, the upper end of the supporting column is fixedly connected to a top plate, an electric push rod is installed at the bottom of the top plate, a base plate is arranged at the lower end of the electric push rod, a groove is formed in the bottom of the base plate, and a limiting spring is connected to the inner wall of the groove. Through mutual cooperation of a clamping groove, a movable rod, a clamping plate, a reset mechanism and other parts, the device can limit and clamp a hot forging workpiece and align and guide the workpiece to the dead center position of the die, blind hole guiding is facilitated, meanwhile, the workpiece is prevented from being adhered to an upper die, and the practicability of the device is improved.
Description
technical field [0001] The invention belongs to the technical field of hot forging equipment, and in particular relates to a blind hole punching hot forging device which facilitates the separation of a punch and a hot forging piece. Background technique [0002] The forging process carried out above the metal recrystallization temperature is called hot forging. Hot forging is also called hot die forging. During forging, the deformed metal flows violently, and the contact time between the forging and the mold is long. Therefore, the mold material is required to have high thermal stability and high temperature strength. And hardness, impact toughness, thermal fatigue resistance and wear resistance, and easy to process, the hot forging die with lighter workload can be made of low alloy steel, and the die is needed when hot forging metal workpieces. [0003] However, after the existing hot forging dies forge the metal workpiece, along with the extrusion of the mold, the heated m...
