The Research Of HC520-3 Hydraulic Shear

The sampling is a necessary step in the process of the high speed wire rolling unit. While there is not online cutting equipment in the wire rolling unit, and the electrical welding would effect the quality of the rolling material, the research of HC520-3 hydraulic shear has been developed.The limit force to cut Φ20mm spring steel was found. Otherwise, based the working principle of the hydraulic shear, the main geometrical parameters , the main performance and the structure parameters were made certain in this paper.In the security analysis of the piston-rod , which is a staff accessory who mainly be compress in work, the security of this staff can be computed as compress intensity of the staff. Both the compress stress and compress intensity are normal random variable, and the probability density function is obey the normal school.The HC520-3 hydraulic shear has been researched and produced. And the cutting experiment has been done. It has been proved that the hydraulic shear can cut 020mm high-alloy steel, spring steel and chrome stainless steel fast. The hydraulic shear can fulfill the request of the working.
