[0002] At present, with the increasing utilization rate of hot die forging presses in the production of mechanical products, the requirements for product production efficiency are also getting higher and higher. Since the hot die forging presses need to frequently change dies during operation to achieve the purpose of producing different products, the die base of the traditional hot die forging press is connected to the die bolts and nuts. When disassembling and installing the die, it is necessary to manually disassemble and assemble the bolts, which is time-consuming. The commonly used rotary cylinder tensioning structure will rotate with the sealing ring during operation, which is prone to wear and leakage. It occupies a large space and cannot adapt to the small internal space of the die changing system inside the hot die forging press. Therefore, the traditional design scheme is difficult to solve the existing problems. Summary of the invention

[0010] A guide block is provided at the middle section of the piston rod, a guide groove is provided on the cylinder body, and the guide block is correspondingly located in the guide groove.
[0011] The utility model is used to cooperate with the installation of an ordinary oil cylinder, fix the ordinary oil cylinder on the transition plate, drive the piston rod to extend during operation, and due to the effect of the multi-thread, the axial movement is converted into rotational movement, driving the front end cover and the transition plate to rotate, and finally achieving the purpose of driving the upper hydraulic oil cylinder to rotate, and the angle range of the transition plate rotation is controlled by controlling the pitch and lead angle of the thread. In order to ensure the stability of the ordinary oil cylinder on the transition plate during rotation, a first bearing mechanism is provided between the front end cover and the cylinder cover, and a second bearing mechanism is provided between the transition plate and the cylinder cover to reduce the friction during rotation and improve the stability of the transition plate. The first bearing mechanism is preferably a deep groove ball bearing, which meets the requirements of reducing the rotation friction of the front end cover and meeting the guiding role. The second bearing mechanism is a thrust bearing to meet the requirements of supporting the transition plate, reducing the friction coefficient of the transition plate rotation, so as to improve the energy conversion efficiency during the movement and improve the stability of the transition plate.
