[0002] A hydraulic press is a machine that uses liquid as the working medium and is made according to Pascal's principle to transfer energy to achieve various processes. A hydraulic press generally consists of three parts: the machine (host), the power system, and the hydraulic control system. Hydraulic presses are classified into valve hydraulic presses, liquid hydraulic presses, and engineering hydraulic presses.

[0003] After searching, a hydraulic press for steel forging (authorization announcement number: CN 217095500U) "comprises a base and a hydraulic device at the upper end of the base, and also includes: a circular groove, arranged at the upper end of the base, wherein a rotating platform is sleeved in the circular groove, and a device groove is provided at the inner bottom of the circular groove; a driving motor, fixedly mounted at the lower end of the base, wherein the output shaft of the driving motor is connected to the rotating platform through a meshing assembly; a lifting assembly, arranged at the lower end of the base and connected to the rotating platform; the utility model will not cause the transmission assembly to be damaged by impact force, thereby ensuring its working stability and service life, and can also prevent the debris generated by forging from affecting the rotation of the rotating platform."

During the hammering process, metal debris may be generated on the surface of the parts and splash out, which may easily cause damage to the operator's face. In response to the above problems, we have launched a hydraulic press for forging parts. Utility Model Content

[0024] In the above technical solution, considering the problem that metal debris is generated on the surface of the parts and splashes out, which is easy to cause damage to the operator's face, in order to solve this problem, the specific operations are as follows:

[0025] Reference Figure 1 - Figure 4 In a preferred embodiment, during the forging process, the protective door 704 always protects the front of the staff to prevent the parts debris from splashing onto the staff. After the forging is completed, the staff holds the handle 14 with their hands and pulls the protective door 704 upwards. The protective door 704 drives the support rod 710 to rotate inside the rotating rod 703, and then the support rod 710 drives the slider 707 to slide outside the slide rod 706, so that the protective door 704 starts to rotate around the top plate 4.

The output end of the No. 2 cylinder 10 drives the two oblique rollers 12 to move in the direction close to the part. Under the clamping of the transverse roller 8, the longitudinal roller 9 and the oblique roller 12, the part is stably fixed on the top of the base 1.

[0027] Reference Figure 1 - Figure 4 In a preferred embodiment, an observation window 13 is provided on the front of the protective door 704.

[0028] Working principle: In actual use, the staff first places the part to be forged on the top of the base 1, and then starts the No. 2 cylinder 10. The output end of the No. 2 cylinder 10 drives the two inclined rollers 12 to move towards the part. Under the clamping of the horizontal roller 8, the longitudinal roller 9 and the inclined roller 12, the part is stably fixed on the top of the base 1. Then start the No. 1 cylinder 5. The output end of the No. 1 cylinder 5 drives the pressing plate 6 to start forging the part. During the forging process, the protective door 704 always protects the front of the staff to prevent the part debris from splashing onto the staff. After the forging is completed, the staff holds the handle 14 with his hand and pulls up the protective door 704, and the protective door 704 drives the support rod 710 to rotate inside the rotating rod 703, and then the support rod 710 drives the slider 707 to slide on the outside of the slide rod 706, so that the protective door 704 starts to rotate around the top plate 4. When it rotates to the appropriate position, the staff removes the part, and under the tension of the spring 708, the protective door 704 is reset. At this point, the staff has completed the protection work of the staff during the forging process of the parts and the positioning and fixing of the parts.
