What are the components of the hydraulic system of the gantry shear

The hydraulic system of the gantry shear is composed of a hydraulic pump (driven by an electric motor), a hydraulic cylinder, a hydraulic control valve, a hydraulic pipeline, an oil tank, a filter and other auxiliary parts. The quantity can be changed according to the model of the gantry shear. The difference.

1. Hydraulic cylinder

The hydraulic cylinder of the gantry shear is a single-rod piston cylinder, and the fixing method is fixed by the cylinder body. Composed of pushing oil cylinder, shearing oil cylinder, pressing oil cylinder, side pressure oil cylinder, closing oil cylinder, etc., it is responsible for converting hydraulic energy into mechanical energy, which is used to drive the actions of each execution slider to complete the compaction and shearing of scrap steel. Cut action.

2. There is a total of one pushing cylinder, which is installed on the support of the pushing table. The front part of the piston rod is equipped with a pusher steel block. Through the forward and backward work of the piston of the pushing cylinder, the process of pushing the scrap steel in the material box is completed.

3. There is one piece (set) of the material pressing oil cylinder, which is installed on the gantry of the shearing machine. The head of the piston rod is connected with the material pressing steel block, and the material pushing device in the material box is completed by the rising and falling of the pressing oil cylinder piston Compressing action of the scrap steel to be cut. There are single-cylinder and double-cylinder press cylinders. Some press material cylinders and shearing cylinders are wrapped with steel plates in the mast, which not only plays a role of dustproof but also is very beautiful.

4. There is one shearing cylinder, which is installed on the mast of the shearing machine. The head of the piston rod is connected with the shearing knife, and the shearing action is carried out on the scrap steel pushed by the pushing device in the material box through the rising and falling of the piston of the shearing cylinder. Due to the different models and the required shearing force, Henan Yuantong Machinery Crusher manufacturer produces hydraulic gantry shears and scrap steel gantry shears. The design and use of the oil cylinder and its control valve block are also different.

5. Cover the oil cylinder, the upper cover is powered and controlled by an oil cylinder. The long upper cover is powered and controlled by two oil cylinders. The head of the piston rod of the oil cylinder is connected with the door cover, and the upper cover of the material box is opened and closed through the rising and falling of the piston rod.

The above cylinders are of double-acting single-piston rod structure. The cylinder barrel is equipped with a piston and a sealing ring, so that the cylinder body forms two front and rear oil chambers, namely the large cavity (or the rear cavity is also called the rodless cavity) and the small cavity ( (Also called the front cavity is also called the rod cavity), when the high pressure oil acts on the front cavity or the rear cavity, the piston and the piston rod are pushed to make a reciprocating linear movement in the cylinder, thereby driving the corresponding device action. The cylinder port of the oil cylinder is provided with a guide sleeve, and a sealing ring is installed on it to support, guide and seal the piston rod.
