1, Host body
The body of the head stretching forming hydraulic press adopts a three beam and four column hydraulic press structure, designed using 3D modeling and computer finite element analysis technology. The main oil cylinder and four (or six. eight) edge pressing cylinders are all installed on the upper crossbeam. The main oil cylinder is a stretching cylinder, which is connected to the piston head through the reserved through-hole on the sliding beam; The edge pressing cylinder is connected to the sliding beam, which drives the annular edge pressing mold to generate edge pressing force. Therefore, it is also known as a non offset head stretching machine in the industry.
The hydraulic press for head stretching and forming can adjust the stretching force and edge pressing force within the range of 0-25MPa according to process requirements. The stretching force can flexibly fluctuate with the edge pressing force, making the head forming effect more in line with production requirements: uniform thickness, standard geometric dimensions, roundness error within ± 0.1mm, smooth surface, and no wrinkles
2, Hydraulic system
The hydraulic system of the head stretching forming hydraulic press adopts integrated control of two-way plug-in valves, with a compact structure, convenient installation and maintenance, and dynamic sensitivity and reliability, high transmission rate, and good sealing performance; Hydraulic control adopts proportional control, with high pressure output accuracy, stable stretching process, and low noise.
3, Online consultation of electronic control system
The electrical control system of the head stretching forming hydraulic press adopts servo+PLC control, equipped with a Japanese Omron industrial touch screen display, which can read and set various parameters on the touch screen, and is connected with high-precision pressure sensors and displacement sensors. It can achieve manual and semi-automatic operation modes, comprehensively considering various production process elements, and achieving a win-win situation of production efficiency and humanization.
The head stretching forming hydraulic press is also equipped with an oil temperature detection device, a forced circulation cooling system (which can ensure that the press is under oil temperature control of 55 ℃), an automatic oil level detection device, a safety emergency stop device, and an anti misoperation stop system. It can also be equipped with a fast automatic feeding device, mold changing device, edge pressing mold locking device, and a movable workbench as needed, thereby improving the mold changing time and efficiency of workers during the mold changing operation, Reduced the cost of molds and the labor intensity of workers, simplifying the process of edge pressing molds. It is also possible to configure the rotation function after the top cylinder is pushed out, which meets the oil coating process of the head during processing.
