Description

Electromagnetic principle-based stable clamping magnetic suction hydraulic clamp

Technical Field

The invention relates to the technical field of hydraulic tongs, in particular to a stable clamping magnetic suction hydraulic tong based on an electromagnetic principle.

Background

The hydraulic crushing pliers push the movable jaw of the crushing pliers to increase or decrease the included angle between the movable jaw and the fixed jaw by a hydraulic oil cylinder so as to realize the purpose of crushing the crushed object. The hydraulic cylinder accelerating valve can increase the running speed of the oil cylinder under the condition that the thrust of the oil cylinder is not changed, and the working efficiency of the hydraulic crushing pliers is increased, so that the hydraulic crushing pliers are commented by users. According to the hydraulic transmission principle, the thrust of the hydraulic cylinder is in direct proportion to the bottom area of the piston of the hydraulic cylinder under the condition that the oil pressure and the flow of the driving hydraulic cylinder are not changed. Meanwhile, the flow of the hydraulic oil is not changed, and the bottom area of the piston of the hydraulic oil cylinder is increased, so that the running speed of the hydraulic oil cylinder is reduced, and the working efficiency of the hydraulic crushing pliers is not improved. To address this situation, we propose a stable clamping magnetic suction hydraulic tong based on electromagnetic principle.
