Hydraulic feeding device

Abstract

The invention discloses a hydraulic feeding device. The hydraulic feeding device is fixed to the ground through four cylindrical legs. After a base is fixed to the ground, a rotating hydraulic table is fixed to the base, the rotating angle of the rotating hydraulic table is controlled hydraulically, the rotating range is 0-24 degrees, and a liquid inlet controls entering and exiting of liquid media. Then, a screw device is installed on the rotating hydraulic table and is connected and fixed through a bolt, and three screw pillars are arranged and are shown in the drawing. Afterwards, a corresponding hydraulic cylinder is installed on a square positioning box, the square positioning box is provided with three threaded holes matched with the screw pillars, the positioning box is arranged on a screw in a sleeving manner, and the height adjusting range of the positioning box is 200-800 mm. A feeding jaw is connected with the top of the hydraulic cylinder, and therefore the running length of the feeding jaw can be adjusted along with stretching and contracting of the hydraulic cylinder, wherein the length adjusting range of the feeding jaw is 160 mm-960 mm.

Description

technical field [0001] The invention relates to the field of metallurgical forging, in particular to a hydraulic feeding device. Background technique [0002] Hydraulic transmission is a form of transmission in which fluid is used as the working medium to transmit and control energy. Compared with electric drive and mechanical transmission, hydraulic transmission has the advantages of large output force, compact structure, small volume, convenient speed regulation and easy control, so it is widely used in construction machinery, construction machinery and machine tools and other equipment. [0003] Modern hydraulic transmission technology was promoted by the rising and flourishing oil industry in the 19th century. The earliest successful hydraulic transmission device was the turret indexer on the ship. Later, hydraulic hexagonal lathes and grinding machines appeared, and some general-purpose lathes came to Hydraulic transmission was not used until the late 1930s. During Wo...
