3000t head hydraulic press_3000t head stretching machine

The head hydraulic press is a head cold pressing one-step forming equipment, also known as head stretching machine, head stretching hydraulic press, head forming hydraulic press, etc. According to the material and process of the head, there are four-column type, frame type and other structures. Considering the cost of the machine, the four-column head hydraulic press is more commonly used, economical and practical, with high production efficiency; the formed head has no flash, uniform thickness, and is quickly formed in one step. The machine is mainly suitable for cold and hot forming of various pressure vessel heads, and can also be used for drum pressing, folding, and leveling of various thick and thin steel plates.

This machine is a 3,000-ton four-column hydraulic press. The machine body adopts a three-beam four-column structure with a pressure cylinder. It can produce cold-pressed heads with a diameter range of 1 meter to 1.8 meters. The thickness of the material plate is 5mm to 6mm, and the stretching height (head bulging height) is 200mm to 350mm. This type of head hydraulic press generally uses a sliding beam as a pressure beam, and the main cylinder passes through the middle of the sliding beam to provide stretching force. The machine's pressure cylinder can be used as a buffer device, and can also be used for blanking and punching. The working pressure of each cavity can be adjusted separately under the pressure set by the system. In order to ensure the quality of stretching and pressure, the head hydraulic press has added a pressure cylinder pressure maintenance system.

3000 ton head hydraulic press structure:

1. Main body

The 3000-ton head hydraulic press adopts a three-beam four-column structure, designed using 3D modeling and computer finite element analysis technology. The main cylinder and four (or six or eight) edge-holding cylinders are installed on the upper crossbeam. The main cylinder is a stretching cylinder, which passes through the reserved through hole on the slide beam and is connected to the piston head; the edge-holding cylinder is connected to the slide beam, and the slide beam drives the annular edge-holding die to generate edge-holding force. Therefore, it is also called a non-offset head stretching machine in the industry.

2. Main cylinder: It adopts a single cylinder structure and is arranged in the upper crossbeam. The cylinder body is fixed to the upper crossbeam through a flange, and the piston rod is connected to the movable crossbeam through a connecting flange. The cylinder body is made of high-quality 45# steel forging to ensure uniform material quality; all piston rod surfaces are quenched and hard chrome plated, and the oil cylinder is subjected to a pressure test (1.1 times). The oil cylinder uses high-quality sealing elements to ensure reliable sealing performance, no leakage, and easy maintenance.

3. Hydraulic system

The hydraulic system adopts two-way cartridge valve integrated control, which has compact structure, easy installation and maintenance, sensitive and reliable movement, high transmission rate and good sealing. The hydraulic control adopts proportional control, with high pressure output accuracy, stable stretching process and low noise.

4. Electronic control system

The 3,000-ton end stretching machine's electronic control system uses servo + PLC control and is equipped with a Japanese Omron industrial touch-screen display. It can read and set various parameters by touch, and is connected to high-precision pressure sensors and displacement sensors. It can realize manual and semi-automatic operation modes, taking into account all factors of various production process links to achieve a win-win situation of production efficiency and humanization.

Technical advantages of hydraulic head press:

1. The head hydraulic press is used for cold and hot forming of various pressure vessel heads, and can also be used for drum pressing, folding and leveling of various thick and thin steel plates.

2. The shapes generally pressed include sphere, ellipse, dish, spherical crown, cone shell and flat cover, etc., which can all be pressed and formed using a four-column hydraulic press.

3. The head hydraulic press has an independent electrical control system and PLC control, with reliable working sensitivity.

4. It can realize two molding processes: fixed stroke and fixed pressure. The working pressure and stroke can be adjusted within the specified range according to the process needs.

5. It has a wide range of applications and can be equipped with molds and automatic feeding devices to complete automated production lines and improve work efficiency.
