Description

Technical Field

[0001] The utility model relates to the technical field of punching dies, in particular to a sheet metal precision disc gear cold extrusion multi-hole punching die. Background Art

[0002] A die is a special process equipment used to process materials into parts or semi-finished products in cold stamping. A die is a process equipment installed on a press, consisting of an upper and lower part that cooperate with each other. In the production and processing of sheet metal precision disc gears, a multi-hole die mold is required to perform multi-hole die operations on the surface of the sheet metal precision disc gear.

[0003] The existing sheet metal precision disc gear punching die operation usually involves placing the sheet metal precision disc gear into the inner side of the lower die and performing a multi-hole punching operation. After the punching is completed, the sheet metal precision disc gear returns to the inner side of the lower die. When the sheet metal precision disc gear needs to be taken out, it needs to be taken out from the inner side of the lower die. However, due to the small removal space, the sheet metal precision disc gear is easily fallen off when taking out the sheet metal precision disc gear, resulting in damage to the sheet metal precision disc gear. Therefore, a sheet metal precision disc gear cold extrusion multi-hole punching die is proposed to solve the above problem. Utility Model Content
