Abstract

The invention discloses a stamping die punch, which consists of the following ingredients in parts by weight: 200-300 parts of iron, 6-12 parts of silicon, 4-8 parts of titanium, 1-5 parts of zinc, 2-8 parts of cerium, 2‑6 parts of molybdenum, 3‑7 parts of tin, 2‑8 parts of gallium, 10‑20 parts of manganese, 2‑8 parts of nickel, 2‑6 parts of yttrium, and 4‑8 parts of lanthanum. The composition formula of the present invention is reasonable, has excellent high temperature resistance, high wear resistance, high thermal conductivity, high heat fatigue resistance, good toughness and high temperature oxidation resistance, etc. The impact force will not cause the working layer to peel off from the punch, and it has excellent material properties and use effects.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to a stamping die punch. Background technique [0002] Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called cold stamping die (commonly known as cold stamping die). Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. [0003] The die punch is a consumable part of the die-casting machine in stamping and casting. It must be in contact with molten aluminum water above 700°C during work, and it must be subjected to repeated cold and hot cycles. This working condition requires that its material must have good High temperature strength, high wear resistance, high thermal conductivity, high thermal fatigue strength and go...
