Improved novel hydraulic linkage counter-blow hammer

Abstract

The invention relate to the technical field of casting punching, in particular to an improved novel hydraulic linkage counter-blow hammer. The improved novel hydraulic linkage counter-blow hammer comprises a frame body, an upper hammerhead, a lower hammerhead, an upper hydraulic linkage oil cylinder, a lower hydraulic linkage oil cylinder, a middle hydraulic linkage oil cylinder and an electromagnetic control system. The upper hydraulic linkage oil cylinder is arranged on the upper hammerhead and drives the upper hammerhead to move up and down. The lower hydraulic linkage oil cylinder is arranged under the lower hammerhead and drives the lower hammerhead to move up and down. The middle hydraulic linkage oil cylinder is arranged between the upper hammerhead and the lower hammerhead. The electromagnetic control system comprises a first electromagnetic valve, a second electromagnetic valve and a third electromagnetic valve. The first electromagnetic valve is electrically connected with the upper hydraulic linkage oil cylinder. The second electromagnetic valve is electrically connected with the lower hydraulic linkage oil cylinder. The third electromagnetic valve is electrically connected with the middle hydraulic linkage oil cylinder.

Description

technical field [0001] The invention relates to the technical field of casting stamping, in particular to an improved novel hydraulic linkage counter-hammer. Background technique [0002] The traditional hammer power uses compressed air or steam. Due to the large compressed air or steam transmission pipeline, there is a large amount of leakage, and the energy profit margin is very low. At the same time, a large amount of waste gas or waste water is discharged during the working process, which pollutes the environment; in addition The traditional linkage of the upper and lower hammer heads of the counter hammer uses a steel belt or a wire rope to achieve linkage. This structural equipment has a large structural size and a short service life of the steel belt or wire rope. Once the steel belt or wire rope breaks, safety accidents will occur. When in use, the service life of the hammer head is short and cannot meet the requirements of use; at the same time, the general counter ...

[0002] The traditional hammer power uses compressed air or steam. Due to the large compressed air or steam transmission pipeline, there is a large amount of leakage, and the energy profit margin is very low. At the same time, a large amount of waste gas or waste water is discharged during the working process, which pollutes the environment; in addition The traditional linkage of the upper and lower hammer heads of the counter hammer uses a steel belt or a wire rope to achieve linkage. This structural equipment has a large structural size and a short service life of the steel belt or wire rope. Once the steel belt or wire rope breaks, safety accidents will occur. When in use, the service life of the hammer head is short and cannot meet the requirements of use; at the same time, the general counter hammer does not have a stroke alarm device, which often causes the situation of being stuck due to excessive expansion and contraction after long-term use; and now Some hammers are completed in the form of manual control, which greatly increases the cost of investment and wastes human resources
