Description

High-safety electro-hydraulic press

Technical Field

The utility model relates to the technical field of presses, in particular to a high-safety electrohydraulic press.

Background

A hydraulic press is a mechanical device that uses a liquid (typically oil) as a transmission medium for applying pressure or force. The hydraulic system converts the liquid pressure into mechanical force, so that the process operations of pressing, forming, bending, shearing and the like of a workpiece are realized. The hydraulic press is widely applied to industries such as metal processing, plastic molding, rubber products, wood processing and the like, and has the characteristics of high precision, high efficiency, good stability and the like.

Through the search, the hydraulic press disclosed in the authorized publication number CN208712560U relates to the technical field of engineering machinery and aims to solve the problem that the hydraulic press is insufficient in stroke due to overlarge shape gap of workpieces. The technical key points are as follows: the press comprises a base, a frame arranged on the base and a hydraulic cylinder arranged on the top wall of the frame, wherein an upper die is connected to a piston rod of the hydraulic cylinder, a longitudinal adjusting mechanism and a transverse adjusting mechanism are arranged on the base, the longitudinal adjusting mechanism comprises a plurality of groups of jacking mechanisms arranged on the base, an operating table is connected to the jacking mechanisms, a first sliding rail is arranged on the upper surface of the base, a supporting seat is connected to the first sliding rail in a sliding manner, the side edge of the operating table is abutted to the supporting seat, the transverse adjusting mechanism comprises a plurality of groups of second sliding rails which are arranged on the operating table and are parallel to each other, an adjusting block connected with the second sliding rails through screws is arranged on each group of second sliding rails, and the adjusting blocks are symmetrically distributed about the central point of the upper die. The machine table improves the application range of the machine table by arranging the longitudinal and transverse adjusting mechanisms.

However, the above design has the disadvantage that when the workpiece is flattened, the workpiece is not positioned, so that the workpiece may shift during the pressing process, the pressing position is inaccurate, or the workpiece is deformed or damaged, and meanwhile, the workpiece is easy to cause unexpected damage due to out-of-control release of the workpiece caused by lack of fixation during the pressing process, so that the safety of the press is reduced, and therefore, we propose a high-safety electro-hydraulic press to solve the problem.
