Description

Technical Field

[0001] The invention relates to the technical field of hydraulic presses, in particular to an automatic lifting hydraulic press. Background Art

[0002] Automatic lifting hydraulic press is a mechanical equipment that realizes lifting function through hydraulic system. It is usually composed of workbench, oil cylinder, oil pump, control valve, etc. When working, the oil pump sends hydraulic oil into the oil cylinder to push the piston up or down, thereby realizing the lifting of the workbench. Automatic lifting hydraulic press has the advantages of smooth lifting, high precision and large carrying capacity. It is widely used in various industrial fields, such as automobile manufacturing, aerospace, electronic equipment, etc. When using automatic lifting hydraulic press, you need to pay attention to safe operation and regular maintenance to ensure the normal operation and service life of the equipment.

[0003] When the existing automatic lifting hydraulic press is in use, the staff places the workpiece to be processed, and then manually controls the limit plate to limit the workpiece. After the processing is completed, the staff manually controls the limit plate to move away from the workpiece again. The staff then removes the processed workpiece, and then places the workpiece to be processed, and then limits the position. This operation method is relatively cumbersome and very inconvenient.

When in use, the hydraulic cylinder will push the lower pressure plate to move downward, and the lower pressure plate will also drive the special-shaped extrusion block to move downward. When the inclined surface of the special-shaped extrusion block contacts the inclined surface of the special-shaped slider, the special-shaped extrusion block will push the special-shaped slider to one side, so that the special-shaped slider slides in the slide groove. When the two special-shaped sliders approach each other, they will squeeze the buffer rod 1 and the spring 1, so that the limit plate limits the workpiece. When the hydraulic cylinder drives the lower pressure plate to move upward, the special-shaped extrusion block will also move upward, and the special-shaped slider will be reset under the elastic recovery capacity of the spring 1.

[0024] In this embodiment, Figure 1 and Figure 4As shown, the processing assembly 3 includes a slide rod 301, which is fixedly connected to the top of the processing table 1, and the top of the slide rod 301 is fixedly connected to a load-bearing block 302, and the top of the load-bearing block 302 is fixedly connected to a hydraulic cylinder 303, and the transmission end of the hydraulic cylinder 303 is fixedly connected to a hydraulic rod 304, and the hydraulic rod 304 is fixedly connected to the lower pressure plate 208.

At the same time, the shaped slider 202 will be reset under the elastic recovery ability of the spring 204, and there is no need for the staff to manually control the limit plate 206 to limit the position.

[0026] In this embodiment, Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the disassembly component 4 includes a placement table 401, which is movably connected to the top of the processing table 1. A limiting hole 402 is opened on the top of the processing table 1. A buffer rod 403 is fixedly connected to the inside of the limiting hole 402, and a spring 404 is sleeved on the side surface of the buffer rod 403.

A threaded hole 408 is provided inside the placement table 401. When the placement table 401 is worn out after being used for a period of time, the staff can rotate the adjusting knob 407 to screw the threaded rod 406 out of the threaded hole 405 and the threaded hole 408. At this time, the spring 404 no longer squeezes the placement table 401 to bounce up, and the staff can replace the placement table 401.

[0028] In this embodiment, Figure 1 , Figure 2 and Figure 5 As shown, a control panel 5 is fixedly connected to one side of the processing table 1 , a support plate 6 is fixedly connected to the bottom of the processing table 1 , and a base 7 is fixedly connected to the bottom of the support plate 6 .

[0030] In this embodiment, Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the limiting holes 402 are distributed in a rectangular array, and the threaded rod 406 is matched with the threaded hole 1 405 and the threaded hole 2 408 .

[0031] The use method and advantages of the present invention: When the automatic lifting hydraulic press is used, the working process is as follows:

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, when using the device, the staff puts the workpiece to be processed on the placement table 401 and then starts the hydraulic cylinder 303. The hydraulic cylinder 303 pushes the hydraulic rod 304 downward, and the hydraulic rod 304 pushes the lower pressure plate 208 to move downward. When the lower pressure plate 208 moves downward, it will drive the sliding ear 305 to slide on the sliding rod 301, and the downward movement of the lower pressure plate 208 will also drive the special-shaped extrusion block 210 to move downward through the L-shaped connecting rod 209. When the inclined surface of the special-shaped extrusion block 210 contacts the inclined surface of the special-shaped slider 202, the special-shaped extrusion block 210 will push the special-shaped slider 202 to one side, so that the special-shaped slider 202 slides in the slide groove 201. When the two special-shaped sliders 202 approach each other, they will squeeze the buffer rod 203 and the spring 20 4, so that the rubber block 207 contacts with the workpiece, the limit plate 206 is limited, and after the lower pressure plate 208 completes processing of the workpiece, the hydraulic cylinder 303 drives the lower pressure plate 208 to move upward, and the special-shaped extrusion block 210 will also move upward, and will no longer push the special-shaped slider 202. At the same time, the special-shaped slider 202 will be reset under the elastic recovery ability of the spring 1 204, and the staff does not need to manually control the limit plate 206 to limit. When the placement table 401 is worn after being used for a period of time, the staff can rotate the adjusting knob 407 to screw the threaded rod 406 out of the threaded hole 1 405 and the threaded hole 2 408. At this time, the spring 2 404 no longer squeezes the placement table 401 to bounce up, and the staff can replace the placement table 401.
