Pressure relief and pressurization system of punching equipment based on quick die change and method

Abstract

The invention discloses a pressure relief and pressurization system of punching equipment based on quick die change and a method , and relates to the technical field of punching equipment. The pressure relief and pressurization system comprises an equipment body and a punching die; a pair of first pipelines are connected to the equipment body side by side; first valves are arranged on the first pipelines, and one ends of the first pipelines are connected with female joints; a pair of second pipelines are connected to the punching die side by side; the second pipelines are provided with second valves, and one ends of the second pipelines are connected with male connectors; the two second pipelines are respectively connected with a third pipeline and a fourth pipeline; the third pipeline and the fourth pipeline are connected to an oil storage tank; and an oil pump and a pressure gauge are arranged on the third pipeline or / and the fourth pipeline. The pressure relief and pressurization system is additionally arranged between the equipment body and the punching die, rapid die replacement of the punching equipment can be conveniently achieved, meanwhile, the operation difficulty of operators is effectively reduced, and high market application value is achieved.

Description

technical field [0001] The invention belongs to the technical field of punching equipment, and in particular relates to a pressure relief and boosting system and method for punching equipment based on quick die change. Background technique [0002] During the manufacturing process of refrigerator cabinets, sheet metal parts need to be punched. The punching equipment works by transmitting pressure through hydraulic oil, and the hydraulic value in the equipment is relatively high. The equipment is divided into two parts, one is the main body of the equipment, and the other is the punching die; the main body of the equipment and the punching die are connected by a male joint and a female joint. Since there are many types of refrigerator cabinets produced, different types of punching dies need to be replaced during the production process. [0003] In the prior art, the way to replace the punching die is: first close the old valves of the main body of the equipment and the respe...

AI Technical Summary

Problems solved by technology

Due to the large hydraulic pressure in the main body of the equipment and the punching die (generally above 7MPa), the operator needs to use tools such as wrenches to dismantle the joint between the main body of the equipment and the punching die, but it is still difficult and usually requires It takes about 15 minutes to complete the replacement of the punching die, which greatly increases the work intensity of the operator
