Problems solved by technology

However, the existing hydraulic presses, especially single-column hydraulic presses, are only provided with one hydraulic cylinder, which limits the processing capacity.
Moreover, the existing hydraulic machine pillars are all fixed in height, which leads to inconvenient operation and is not conducive to adjustment.
In addition, the hydraulic cylinder also needs to be refueled in time, and the oil pump and oil pipe for refueling are placed in a mess, which is inconvenient to operate and prone to confusion, and the efficiency is relatively low

Abstract

The invention discloses a hydraulic machine with an impact correction device. The hydraulic machine comprises a base, a four-column frame, a stamping device, a hydraulic oil cylinder and a PLC control device. The stamping device is connected to the top position of the four-column frame to conduct up-down stamping. The hydraulic oil cylinder is connected with an oil supply device through a three-way overflow valve. The impact correction device comprises a flexible impact ring, an elevation device and a back-flushing hydraulic oil cylinder. The flexible impact ring is fixed to the top position of the base through the elevation device. The other end of the three-way overflow valve is connected with the elevation device of the impact correction device so that the flexible impact ring can be opened or locked, and the back-flushing hydraulic oil cylinder is supported at the bottom of the base through a jack structure. According to the hydraulic machine, the flexible impact ring is arranged above the base, the flexible impact ring is jacked up through the back-flushing hydraulic oil cylinder and the jack structure of the impact correction device, and relief of the overlarge stamping force of the stamping device is achieved.

Description

Technical field [0001] The invention relates to the technical field of hydraulic presses, in particular to a hydraulic press with an impact correction device. Background technique [0002] The hydraulic press is a machine that uses hydrostatic pressure to process metal, plastic, rubber, wood, powder and other products. [0003] It is often used in pressing process and press forming process, such as: forging, stamping, cold extrusion, straightening, bending, flanging, sheet deep drawing, powder metallurgy, pressing and so on. Existing hydraulic presses are divided into four-column type, horizontal type, vertical type frame and multi-layer steel belt winding frame according to their structure. Among them: medium and small vertical hydraulic presses often use single-column type, also known as C-frame type. Single-column type hydraulic presses are open on three sides for operation. However, various existing hydraulic presses, especially single-column hydraulic presses, are provided w...
