Novel hydraulic oil cylinder for brake type plate shearing machine

Abstract

The invention discloses a novel hydraulic oil cylinder for a brake type plate shearing machine. The hydraulic oil cylinder comprises a cylinder bottom, a cylinder barrel and a lug ring, the cylinder bottom and the cylinder barrel are fixedly connected, a mounting hole is formed in the cylinder bottom, a first universal bearing is arranged in the mounting hole, a grease fitting is arranged on the cylinder barrel, a lug hole is formed in the lug ring, a second universal bearing is arranged in the lug hole, a piston rod is fixedly connected on the lug ring, the piston rod extends into the cylinder barrel, a piston is connected on the piston rod, a guide sleeve is arranged in the cylinder barrel, the piston rod penetrates through the guide sleeve, a cylinder cover is arranged at the end part of the cylinder barrel, and a dustproof ring is arranged in the middle of the cylinder cover. According to the hydraulic oil cylinder, the hydraulic oil cylinder is connected with a machine tool through the universal bearings, the lateral force during working of the machine tool can be thoroughly eliminated, the device abrasion can be reduced, meanwhile, the overload of the machine tool can be relieved, and a good machine tool working condition can be created.

Description

technical field [0001] The invention relates to the field of hydraulic oil cylinders, in particular to a hydraulic oil cylinder for a novel gate-type shearing machine. Background technique [0002] In mechanical processing, gate shears are often used, and the hydraulic system is an important component of the gate shears. Traditional hydraulic cylinders are generally connected to the machine tool through joint bearings. When the hydraulic cylinder is working , will generate a large lateral force, will accelerate the wear of the device, and the overload load of the machine tool is also large. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned problems existing in the prior art, and provide a new type of hydraulic cylinder for a gate-type shearing machine. The hydraulic cylinder is connected to the machine tool through a universal bearing, which can completely eliminate the lateral force when the machine tool is working,...
