Description

Technical Field

[0001] The utility model relates to the technical field of hardware fittings moulds, in particular to a stamping mould for gear-digging hardware fittings. Background Art

[0002] Tooth hardware is used for the tooth parts of tunnel boring machines. Teeth are usually produced according to their own size and quality. Larger teeth are usually manufactured using forging and other processes, while smaller teeth are usually made using stamping dies.

[0003] The existing excavator tooth stamping dies are not convenient for safely removing the finished excavator tooth from the mold after stamping.

[0004] The reason for this problem is that the stamping die places the raw materials of the excavating teeth inside the model groove, and then uses a hydraulic telescopic rod to drive the stamping plate to move downward, so that the stamping plate drives the stamping template to stamp downward, and finally the excavating teeth are stamped and formed inside the stamping template and the mold body. In order to facilitate the stamping and forming of the excavating teeth to be more stable, the excavating teeth are usually heated. After the excavating tooth hardware is stamped and formed, the surface temperature of the excavating teeth after stamping is high. At this time, other tools can only be used to remove the excavating teeth inside the model groove, and the finished excavating teeth will fit into the model groove inside the mold body, and half of the excavating teeth will be located inside the model groove after stamping, which makes it difficult to use tools to remove them. At the same time, it is not easy to hold the tool clamping position, which will also cause certain wear on the surface of the finished excavating teeth, causing certain troubles to the excavating tooth hardware forming molds. Therefore, we propose a stamping die for excavating tooth hardware accessories. Utility Model Content
