Abstract

The invention discloses a hard cold stamping die. The die comprises, by weight percent, 35%-60% of copper, 5%-13% of chromium, 18%-22% of iron, 3%-6% of aluminum, 0.8%-1.2% of tin and 1%-3% of molybdenum. The raw material ratio of the hard cold stamping die is scientific and reasonable, the structural stability is high, the mechanical strength of the die is greatly improved, and the phenomena of opening collapsing and cracking can be effectively avoided.

Description

A kind of hard cold punching die
Technical field
The present invention relates to a kind of mould, be specifically related to a kind of hard cold punching die.
Background technology
Cold punching die, mostly is and is arranged on forcing press, at room temperature applies deformation force to being placed on interior plate, makes It is deformed, thus obtains definite shape, the special specific purpose tool of the product parts of size and performance.The material of mould is direct Affecting Yield and quality and the cost of stamped workpieces, existing cold punching die mostly is copper-iron alloy or albronze mould, by Relatively low in intensity, chipping and cracking phenomena easily occur after Multi-step forming.
Therefore, for solving the problems referred to above, a kind of new technical scheme of special offer.
Summary of the invention
The present invention provides a kind of hard cold punching die.
The technical solution used in the present invention is:
A kind of hard cold punching die, including the raw material of following percentage by weight:
Copper 35-60%；
Chromium 5-13%；
Ferrum 18-22%；
Aluminum 3-6%；
Stannum 0.8-1.2%；
Molybdenum 1-3%.
Further, the nickel of percentage by weight 0.6-0.8% can also be added
Further, the percentage by weight of described copper is 46%.
Further, the percentage by weight of described ferrum is 19.5%.
Further, the particle diameter of each raw material is 7-10 micron.
Beneficial effects of the present invention: the proportioning raw materials of this hard cold punching die is scientific and reasonable, structural stability strong, significantly Improve mould machine intensity, can be prevented effectively from
Chipping and cracking phenomena.
