Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic presses, and more specifically, relates to a hydraulic press with a protective function. Background Art

[0002] Hydraulic presses can be used for forging, stamping, cold extrusion, straightening, bending, and flanging. During the operation of the hydraulic press, when the press seat gradually applies pressure on the workpiece, or when two parts are fitted under the hydraulic press, the parts may break due to uneven force or material problems of the parts. At the same time, the workpiece may also break due to insufficient friction between the contact surface of the press seat and the workbench under pressure.

[0003] Existing similar hydraulic presses are not easy to automatically protect when working on parts. When the hydraulic press is working, parts flying outwards may easily cause injuries, and the force of the flying parts fragments is too strong to easily affect the service life of the device's protective plate.

The structures of the front protective frame 4 and the side protective frames 5 are the same. A group of limit blocks 303 are slidably installed at the front end of the mounting frame 3, and a group of limit slots 402 are opened at the front end of the front protective frame 4. The limit blocks 303 at the front end of the mounting frame 3 are inserted and installed in the limit slots 402 at the front end of the front protective frame 4. A protective plate 501 is slidably installed on the inner side of the side protective frame 5, and two groups of sliding blocks 5022 are slidably installed at both ends of the inner side of the side protective frame 5. The outer ends of the sliding blocks 5022 are respectively rotatably installed with a group of rotating plates 503, and the outer ends of the rotating plates 503 are respectively rotatably installed on the outer ends of the protective plates 501.

[0028] like Figure 2 The second end of the second stop 502 is fixed on the second end of the second stop 502, and the third end of the second stop 502 is fixed on the second end of the second stop 502.

[0029] Example 2: Based on Example 1, Figures 3 to 5As shown, a group of connecting plates 3011 are fixedly installed at both ends of the mounting groove 301, and a sliding hole is opened on the connecting plate 3011.

After the bottom ends of the front protective frame 4 and the side protective frame 5 come into contact with the top surface of the base 1, the pressure head 201 continues to move downward, and the second elastic member 4011 The limit block 303 is compressed so that the device can automatically protect itself through the front protective frame 4 and the side protective frame 5 when operating, thereby improving the safety of the device. The limit block 303 is pulled outward and the front protective frame 4 is pushed upward. After the front protective frame 4 moves to the fixed position, the limit block 303 is released. Under the action of the first elastic member 3031 on the connecting rod 3032, the limit block 303 moves inward, and the limit block 303 at the front end of the mounting frame 3 is inserted and installed in the limit groove 402 at the front end of the front protective frame 4, so that the front protective frame 4 of the device can be easily pulled upward to limit the rear position, so as to disassemble and assemble parts, making the device more practical.
