Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic machinery equipment, and more specifically, particularly relates to a hydraulic press with a cylindrical structure. Background Technique

[0002] When pulling out the shaft pin of mechanical equipment, a cylindrical hydraulic press is generally used for operation. When the existing cylindrical hydraulic press tops and pulls out the shaft pin, generally, the piston rod of the cylindrical hydraulic press needs to be connected to the shaft pin, and then by turning on the hydraulic press, the piston rod of the hydraulic press drives the shaft pin to be topped and pulled out.

[0003] The existing application number is: CN201620814057.X. The utility model discloses a hydraulic press with a cylindrical structure, using a pipe fitting as a connecting frame. The main oil cylinder is arranged at one end of the pipe fitting, a punch or an extrusion head is arranged at the front end of the piston rod of the main oil cylinder, a forming die is arranged at the other end of the pipe fitting or in the middle position of the pipe fitting, and a feeding cavity is arranged in front of the forming die, between the main oil cylinder and the forming die. The central axes of the main oil cylinder and the die are both on the same horizontal or vertical straight line. The utility model uses a pipe fitting to replace the multi-guide column structure in the prior art, directly fixes the oil cylinder or the die at the end or in the middle of the pipe fitting, and also replaces the upper and lower beam structures in the prior art with connection methods such as threads, keyways or flanges to form a hydraulic press with a cylindrical structure, thus saving a large number of parts, especially the large-diameter guide columns with high processing costs and the connecting beams at both ends of the oil cylinders. The overall volume of the hydraulic press is significantly reduced, the structure is more compact, and transportation, installation and maintenance are more convenient, with remarkable economic benefits.

[0004] Based on the above, when the existing shaft pin is ejected, the worker needs to align the piston rod of the hydraulic press with the shaft pin first and then fix the hydraulic press. However, since the diameters of many connected shaft pins are small, it takes the worker a long time to align the piston rod with the shaft pin, and the operation is rather cumbersome, affecting the ejection efficiency of the shaft pin.

[0048] The ejection mounting plate 3 is fixedly connected to the lower end of the hydraulic press main body 1;

[0049] Two groups of portable handles 4 are provided, and the two groups of portable handles 4 are respectively fixedly connected to the left and right sides of the hydraulic press main body 1;
