Application Case of 3000 Ton Dual-Action Thin Plate Stretching Hydraulic Press Manufacturer
A dual-action hydraulic press, also known as a dual-action stretching hydraulic press or a dual-action thin plate stretching hydraulic press, is primarily used for processes such as thin plate stretching, bending, forming, and can also be employed for plastic compression, cold extrusion bending, shaping correction, and pressing operations. Depending on the thickness and width of the plate, machines with suitable tonnage are selected, commonly available in 500 tons, 1000 tons, 2000 tons, 3000 tons, etc. The mentioned dual-action thin plate stretching hydraulic press in this context has a tonnage of 3000T, specifically designed for sheet metal stretching and forming. The equipment is characterized by low energy consumption, high efficiency, innovative design, safety protection devices, automatic counting function, and dual-speed control of the moving beam: fast in idle mode, slow during tool approach, and stretching. The main cylinder and side cylinder feature lower limit protection, and the setting of upper and lower limit positions for the stroke is simple, convenient, and quick.
In the design of the 3000-ton dual-action thin plate stretching hydraulic press, it has an additional horizontal beam compared to the three-beam four-column hydraulic press, also known as the side pressing beam. This beam is used to press the product, while the main cylinder drives the mold for stretching and forming the product. Therefore, this equipment is also referred to as a 3000-ton four-beam four-column stretching hydraulic press. The 3000-ton dual-action thin plate stretching hydraulic press is considered a dedicated machine designed for the production of large-scale stretched products.
The primary structural feature of the 3000-ton dual-action thin plate stretching hydraulic press is the presence of inner and outer movable beams, with the stretching beam inside and the side pressing beam outside. During dual-action stretching, the stretching and side pressing beams can descend rapidly together, switch to slow descent when approaching the workpiece, and when the side pressing beam presses around the workpiece, it transitions to a pressure-maintaining state. At this point, the stretching beam continues to descend for stretching. After completing the stretching process, the stretching beam can maintain pressure with a delay, release pressure, and quickly return, while the side pressing beam also releases pressure and quickly returns. Then, the hydraulic pad and the top rod push the workpiece out. The 3000-ton dual-action thin plate stretching hydraulic press can also link the stretching and side pressing beams together using locating pins or pull rods to achieve single-action operation, where the pressing force will be the sum of the two.
Operation Modes:
1. Adjustment:
- Press the corresponding function button, initiating the corresponding action. Lift the hand to stop. Primarily used for equipment adjustment and inspection.
2. Manual:
- Press the corresponding function button, completing a corresponding action. Continue the manual action to the end by lifting the hand, but without sending a signal for the next action.
3. Semi-Automatic:
- Press the pressing button to automatically complete a specified action cycle.
Process Actions of the 3000 Ton Dual-Action Thin Plate Stretching Hydraulic Press:
- Two types: "no ejection" and "ejection," selected using the toggle switch on the control panel. When used for ejection, it has an ejection delay function, and the delay time can be preset and adjusted.
1. No Ejection:
- Rapid descent of the slider → Slow descent for pressure → Slow pressure holding, delay, and pressure relief → Slider return.
2. Ejection:
- Rapid descent of the slider → Slow descent for pressure → Slow pressure holding, delay, and pressure relief → Slider return → Ejection cylinder ejects → Ejection cylinder retracts.
The 3000-ton dual-action thin plate stretching hydraulic press can also be equipped with a side pressing cylinder for use as a cushioning device. It can also be used for blanking and punching. Under the set pressure of the system, the working pressure of each chamber can be adjusted separately. To ensure the quality of stretching and side pressing, a side pressing cylinder pressure holding system is added. Nadun Machinery Manufacture Co., Ltd. provides customization for dual-action thin plate stretching hydraulic presses with tonnages ranging from tens of tons to several hundred or even thousands of tons. The selection of tonnage is crucial, and the company can recommend the appropriate tonnage based on detailed calculations of the product's tonnage requirements. If you have experience with similar products or have relevant data, you can directly place an order. If you are unsure about tonnage selection, you can send the product's data or mold data to the company for technical analysis and recommendations.
