In the field of industrial manufacturing, head stretching hydraulic presses play a vital role. It is a kind of equipment that operates based on the hydraulic principle and mainly consists of parts such as the machine body, hydraulic system, and molds.
The machine body usually has structural types like the four-column type and frame type. The four-column structure has good stability and can withstand relatively large pressures. During the processing, it ensures the overall firmness and reliability of the equipment and reduces deformation caused by stress. The hydraulic system is the core that drives the operation of the equipment. It converts the mechanical energy of the motor into the pressure energy of hydraulic oil through the oil pump, and then precisely adjusts the pressure and flow rate with the help of control valves to drive the oil cylinders to complete corresponding actions, providing sufficient and precisely controllable force for the forming of the heads. And the molds are specially designed according to the shape and size requirements of different heads. For common heads such as elliptical and spherical ones, there are corresponding molds to achieve precise forming.
Head stretching hydraulic presses have many excellent properties. They can process metal sheets of various materials. According to the preset process parameters, they can precisely control the pressure and stroke so that the wall thickness of the formed heads is uniform and the shapes are standard. Moreover, the one-time forming efficiency is quite high, reducing the subsequent processing procedures and greatly improving the production efficiency. They are widely used in numerous industries.

Next, we will introduce our YQ32-3000T head stretching hydraulic press.
Structural Composition of 3000-ton Head Hydraulic Press:
1.Main Frame
The frame of the 3000-ton head hydraulic press adopts a three-beam and four-column structure, which is designed by using 3D modeling and computer finite element analysis techniques. The main oil cylinder and four (or six, eight) blank holder cylinders are all installed on the upper crossbeam. The main oil cylinder serves as a stretching cylinder, passing through the through holes reserved on the sliding beam and connecting with the piston head. The blank holder cylinders are connected to the sliding beam, and the blank holder force is generated by driving the annular blank holder die through the sliding beam. Therefore, it is also known as a non-counteracting head stretching machine in the industry.
2.Main Cylinder
It adopts a single-cylinder structure and is arranged inside the upper crossbeam. The cylinder body is fixed to the upper crossbeam by flanges, and the piston rod is connected to the movable crossbeam through connecting flanges. The cylinder body is made of high-quality 45# steel forged, ensuring uniform material quality. The surfaces of all piston rods are quenched and hard chrome-plated. The oil cylinder undergoes a pressure resistance test (1.1 times). High-quality sealing elements are used for the oil cylinder to ensure reliable sealing performance, no leakage, and convenient maintenance.
3.Hydraulic System
The hydraulic system adopts two-way cartridge valve integrated control, with a compact structure, convenient installation and maintenance, sensitive and reliable operation, high transmission efficiency, and good sealing performance. The hydraulic control adopts proportional control, with high precision of pressure output, stable stretching process, and low noise.
4.Electric Control System
The electric control system of the 3000-ton head stretching hydraulic press adopts servo + PLC control, equipped with an industrial touch screen display of Omron from Japan. Various parameters can be read and set on the touch screen, and it is connected with high-precision pressure sensors and displacement sensors, enabling both manual and semi-automatic operation modes. It comprehensively takes into account various elements of the production process to achieve a win-win situation in terms of production efficiency and user-friendliness.
Technical Advantages of 3000-ton Head Hydraulic Press:
The head hydraulic press is used for cold and hot forming and pressing of the heads of various pressure vessels, and it can also be used for the bulging, flanging, and leveling processes of various thick and thin steel plates.
Generally, shapes such as spherical, elliptical, dish-shaped, spherical crown-shaped, conical shell, and flat cover can all be formed by pressing with a four-column hydraulic press.
The head hydraulic press has an independent electrical control system, controlled by PLC, with reliable working sensitivity.
It can realize two forming processes, namely fixed stroke and fixed pressure. The working pressure and stroke can be adjusted within the specified range according to the process requirements.
It has a wide range of applications. It can be equipped with molds and automatic feeding devices to form an automated production line and improve work efficiency.
Each head has the same specification without errors, with a low rejection rate, fast speed, and high output.
