Description

Technical Field

[0001] The utility model belongs to the technical field of mandrel processing, and in particular relates to a mandrel fine punching and cutting die. Background Art

[0002] The mandrel fine blanking cutting die is a die used to precisely cut the seat belt mandrel during the production process. It usually includes a die base and an upper die, on which a cutting blade or knife is installed to ensure that the mandrel is cut at a precise position and angle.

[0003] Existing, when cutting, the seat belt mandrel drives the upper mold to move toward one end close to the mold base through the cylinder. When contacting the mold base, the multiple groups of mandrels placed on the mold base are cut by the tool installed at the bottom of the upper mold, so that the frames connected between the multiple groups of mandrels are cut off from the surface of the mandrel, thereby avoiding the multiple groups of mandrels being connected together. Although the multiple groups of mandrels can be separated by cutting the frames through the tool at the bottom of the upper mold, the frame waste of the mandrel after separation is located on the mold base, and the fallen frame waste needs to be collected manually, which makes the collection slower and reduces the cutting efficiency of the mandrel.
