Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment 1: When in use, the material to be processed is placed on the placing table 12 of the machine body 1, and the hydraulic arm 2 is started to drive the bottom pressure block to move, and at the same time drive the sleeve plate 3 to move downward. As the sleeve plate 3 moves downward and squeezes the pushing component 5, the push rod 51 in the pushing component 5 drives the push plate 53 to move downward, and while compressing the spring 2 54, the hydraulic oil in the hydraulic chamber 52 is compressed, so that the hydraulic oil is further squeezed into the assembly chamber 6 through the connecting chamber 8 in the connecting chamber, and is evenly filled into the assembly chamber 6 through the intermediate chamber 7. The hydraulic pressure rises and pushes the protective component 4 upward, so that the protective component 4 moves upward and surrounds the outside of the working interval to be forged. At the same time, the spring 1 43 is stretched. After the protective component 4 is extended, the hydraulic arm 2 that continues to descend drives the pressure block to forge the workpiece, and the protective component 4 moves back and forth up and down to achieve blocking protection of fragments during the forging process.

[0029] Firstly, by utilizing the cooperation of the pushing component 5, the protective component 4 and the sleeve plate 3, during the downward forging period, the protective component 4 is automatically pushed upward to protect the outside of the workpiece in the forging area, effectively avoiding the risk of ejection caused by the workpiece breakage, and the protective component 4 is used to block and protect the ejected fragments. At the same time, the protective component 4 is only actively extended for protection before the pressing block is forged, and is automatically reset and hidden after the forging process is completed. On the one hand, it ensures the observation of the forging state of the workpiece, and on the other hand, it realizes the active hiding of the protective component 4 to avoid occupying space, and the use effect is good.

When the workpiece is a plate-shaped workpiece, the bottom of the workpiece covers the top of the adsorption pipe 91, so that the upper and lower sides of the workpiece are formed.
