Our double-action thin plate stretching hydraulic press has a tonnage of 630T and is specially used for plate stretching and forming. The equipment has low energy consumption, high efficiency, and a novel style. It is equipped with safety protection devices, an automatic counting function, and two-stage speed control of the movable crossbeam. The main cylinder and the edge-pressing cylinder have lower limit protection. The upper and lower limit stroke position settings are simple, convenient, and fast.

The 630-ton double-acting thin plate stretching hydraulic press in Chengdu Zhengxi was designed with one more crossbeam than the three-beam four-column hydraulic press, also called the side-pressing beam. The side-pressing beam presses the product, and the main cylinder drives the mold to stretch the product. Therefore, this equipment is also called a 630-ton four-beam four-column deep drawing hydraulic press. The 630-ton double-acting thin plate stretching hydraulic press is a special machine that specializes in large-scale stretching products.

Main Structural Features of the 630-ton Double-action Thin Plate Stretching Hydraulic Press

There are two movable beams inside and outside; the stretching movable beam is installed inside, and the edge-pressing movable beam is installed outside. When performing double-action stretching, the stretching movable beam and the edge-pressing movable beam can be quickly lowered together and lowered slowly when approaching the workpiece. When the edge-pressing movable beam presses the workpiece around, the edge-pressing movable beam will no longer drop and become a pressure-maintaining state. At this time, the stretching movable beam continues to move downward for stretching.

After stretching, the movable beam can achieve pressure-maintaining delay, pressure relief, and rapid return. The edge-pressing movable beam also relieves pressure and returns quickly, and then the hydraulic pad and ejector push the workpiece out. The 630-ton double-action thin plate stretching hydraulic press can connect the stretching and edge-pressing movable beams together by positioning pins or tie rods to achieve a single action. At this time, the pressing force will be the sum of the two.

Operation Mode of 630-ton Double-action Thin Plate Stretching Hydraulic Press:

1. The 630-ton double-action thin plate stretching hydraulic press has three operation modes: adjustment, manual, and semi-automatic. Each mode can be divided into two working modes: fixed pressure and fixed stroke, which are selected by the conversion switch on the operation panel. The holding time can be preset at 999 seconds.
• Adjustment: Press the corresponding function button to have the corresponding action. Raise your hand to stop. Mainly used for equipment adjustment and inspection.
• Manual: Press the corresponding function button to complete an action. The hand-raising action continues to the end, but the next action is not performed.
• Semi-automatic: Press the pressing button to complete a specified action cycle automatically.

2. The 630-ton double-action thin plate stretching hydraulic press has two process actions: no ejection and ejection. The conversion switch on the operation panel allows you to select either. When used as an ejection process, it has an ejection delay function. The delay time can be preset and adjusted.
• No ejection: Slider descends quickly – Slider descends slowly to suppress – Slider presses quickly to delay and release pressure – Slider returns.
• Ejection: Slider descends quickly – Slider descends slowly to suppress – Slider presses quickly to delay and release pressure – Slider returns – Ejection cylinder ejects – Ejection cylinder returns.

The 630-ton double-acting thin plate stretching hydraulic press can also be equipped with a pressure cylinder, which can be used as a buffer device and for blanking and punching. The working pressure of each cavity can be adjusted separately under the pressure set by the system. A pressure cylinder pressure holding system can be added to ensure the quality of stretching and pressure pressing.

The double-acting thin plate stretching hydraulic press in Chengdu Zhengxi can be customized from tens of tons to hundreds of tons and thousands of tons. Before selecting the tonnage of the hydraulic press, the tonnage required by the product should be calculated in detail. If you choose a large one, the machine cost will be high, and if you choose a small one, the stretched product will not be pressed in place, so the choice of tonnage is very important. If you have experience in making this kind of product before or have made similar products, you can order the machine directly. If you really don’t know how to choose the tonnage, you can send us the product data or the mold data. The company’s technology will calculate and recommend you a double-acting thin plate stretching hydraulic press with a suitable tonnage.
