Process of making steel spade based on continuous cold stamping die

Abstract

The invention relates to hardware manufacturing technologies, in particular to a technology for manufacturing a steel spade based on a continuous cold-punched die. The technology includes the steps that a strip steel coil is put on a carrying bracket with an uncoiling function, and then strip steel is flattened by a flattening machine; the flattened strip steel enters a feeding machine, and the feeding machine feeds materials to a press machine according to a set length; the strip steel sequentially passes through seven working sections of the continuous cold-punched die after entering the press machine, and then punch forming is conducted; the formed spade is subjected to quenching; and rust-proof treatment and packaging are carried out. Production efficiency is obviously improved, and labor expenses are greatly reduced. The work which needs to be completed collaboratively by about ten people in a traditional technology can only be done by 1 person or 2 persons easily, and the cold-punched die is adopted for punch forming. Namely, no heating is required in the forming process of a whole spade body, forming can be conducted smoothly at the indoor temperature, and thus energy consumption and environmental pollution are greatly reduced.

Description

technical field [0001] The invention relates to a process for continuously producing steel shovels, in particular to a process for making steel shovels based on a continuous cold stamping die. Background technique [0002] As a daily tool, steel shovel is closely related to our daily life and production. Especially in rural areas, steel shovel is an indispensable tool for every family. The traditional steel shovel manufacturing process includes: fragmentation, punching, drilling, heating, stamping, rolling forming, trousering, quenching, rolling, spraying or painting, sharpening and packaging. There are following deficiencies in the traditional craft: [0003] 1. The production process is complicated, the production efficiency is low, the labor intensity is high, and multiple people are required to work together. 2. Uneven hand cutting affects the service life of the shovel. 3. The quenching process uses residual temperature quenching, and the temperature is unstable, res...
