Zusammenfassung:	An upper concave plane is arranged on the upper portion of a cylinder, arc supports are formed at the two ends of the upper concave plane, and a hole for a piston rod to enter and exit is formed in the middle of the upper concave plane. An inverted-T-shaped groove is formed in the head of the piston rod and matched with a protruding block at the bottom end of the hot extrusion punch. Rectangular water grooves are formed in the concave faces of the two sides of the cylinder, and the rectangular water grooves in the two sides are communicated through three cooling water pipelines penetrating through the oil cylinder. Spring balls are evenly distributed on the bottom arc of the oil cylinder, and the bottom inlet end of the oil cylinder is chamfered. The oil cylinder is integrally forged by the PCrNi3MoVQ material, so that the high strength of the cylinder body can be ensured. The inlet end of the oil cylinder is chamfered, so that the oil cylinder can conveniently enter and exit from thesuper pipeline; and a wat
