[0004] The utility model is implemented as follows: A double-cylinder stepping upper slide plate for a large die forging hydraulic press, comprising

[0005] A hydraulic press slider, an upper slide plate, an upper slide plate pushing cylinder, a support frame, a moving block, a pin, and an inner pin sleeve. The hydraulic press slider is located on the ground of the die forging hydraulic press. The upper slide plate is installed on the lower plane of the hydraulic press slider. There are two sets of the upper slide plate pushing cylinders, and the two sets of the upper slide plate pushing cylinders are in transmission connection with the upper slide plate. The support frame is installed on the side of the hydraulic press slider. The top of the support frame is flush with the lower plane of the hydraulic press slider.

[0015] The beneficial effects of the present utility model are as follows: A double-cylinder stepping upper slide plate of a large die forging hydraulic press obtained by the above design. When the upper slide plate needs to move horizontally during use, the hydraulic press slider stops moving up and down.

At this time, the moving block, the pin, and the inner pin sleeve are all fixed to the upper slide plate together. Therefore, the movement of the upper slide plate is realized. When one stroke of the upper slide plate pushing cylinder is completed, the pin retracts and separates from the inner pin sleeve. In this way, the upper slide plate pushing cylinder is separated from the upper slide plate. When the pin retracts, the upper slide plate will remain in its original position unchanged. At this time, the pin installed on the moving block will be inserted into the inner pin sleeve installed inside the upper slide plate again. At this time, the moving block connected to the upper slide plate by the upper slide plate pushing cylinder is connected again. When the power system equipped with the large die forging hydraulic press provides power for the upper slide plate and the upper slide plate pushing cylinder, the plunger rod of the upper slide plate pushing cylinder extends, driving the movement of the moving block again. At this time, the moving block, the pin, and the inner pin sleeve are all fixed to the upper slide plate together, realizing the re-movement of the upper slide plate. Repeating like this, the long-stroke stepping of the upper slide plate is realized. Using this structure not only meets the requirement of the long-stroke movement of the upper slide plate under the above forging process, but also effectively reduces the length of the upper slide plate cantilever-mounted on the hydraulic press slider, reduces the equivalent stress of the support frame, extends the service life of the equipment, and effectively realizes the reliability of installation and operation.

[0022] To make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present utility model.

[0023] Please refer to Figure 1 and Figure 2 The present utility model provides a technical solution: A double-cylinder stepping upper slide plate for a large die forging hydraulic press, including

[0024] a hydraulic press slider 1, an upper slide plate 2, an upper slide plate pushing cylinder 3, a support frame 4, a moving block 5, a plug pin 6, and an inner plug pin sleeve 7. The hydraulic press slider 1 is located on the ground of the die forging hydraulic press. The upper slide plate 2 is installed on the lower plane of the hydraulic press slider 1. There are two sets of upper slide plate pushing cylinders 3, and the two sets of upper slide plate pushing cylinders 3 are in transmission connection with the upper slide plate 2. The support frame 4 is installed on the side of the hydraulic press slider 1, and the top of the support frame 4 is flush with the lower plane of the hydraulic press slider 1. The moving block 5 and the plug pin 6 are installed on the support frame 4, and the inner plug pin sleeve 7 is installed on the upper slide plate 2.

[0025] Please refer to Figure 3and Figure 4 The upper slide 2 is slidably installed in the support frame 4. The installation height and working height of the upper slide 2 are both above 8 meters, and it has the functions of moving forward and backward and up and down at the same time. The support frame 4 is provided with a mounting interface for the upper slide 2. The width of the hydraulic press slider 1 is much smaller than the maximum range of the stroke position of the upper slide 2 (the difference is not less than 7 meters). The stroke of the upper slide 2 is very large, about 8-12m, and the stroke of the upper slide 2 is generally above 8 meters. The hydraulic press slider 1 is connected to the upper slide 2, and the upper slide 2 part is cantilevered to form an upper slide cantilever. The load in the cantilever state is not less than 200 tons.

[0026] A guide plate that matches the upper slide 2 is installed under the support frame 4, and the upper slide push cylinder 3 is installed on one side of the support frame 4 and is transmission-connected to the upper slide 2. A guide plate that matches the moving block 5 is arranged inside the support frame 4. The support frame 4 is installed with a guide plate used for moving the upper slide 2 and a guide device for the moving block 5.

[0027] The upper slide plate push cylinder 3 is installed in the support frame 4, the upper slide plate push cylinder 3 is transmitted with the upper slide plate 2, the upper slide plate 2 and the upper slide plate push cylinder 3 drive the upper slide plate 2 to move through the moving block 5, and the moving block 5 connecting the upper slide plate 2 and the upper slide plate push cylinder 3 is installed with a latch 6, which effectively ensures that the upper slide plate 2 and the upper slide plate push cylinder 3 can be flexibly separated and connected according to actual use requirements.

[0028] The latch 6 is limitedly slidably engaged with the upper slide plate 2 and the upper slide plate push cylinder 3. The latch 6 is used in conjunction with the moving block 5. The moving block 5 and the latch 6 are limitedly connected to the upper slide plate 2. The latch sleeve installed inside the upper slide plate 2 is used in conjunction with the latch 6 installed on the moving block 5 to protect the upper slide plate 2 while achieving the connection function. The upper slide plate 2 has multi-station, long-stroke stepping movement, and the latch 6 includes a latch sleeve and a latch.

[0029] Working principle: When the upper slide plate 2 needs to move horizontally, the slider 1 of the hydraulic press stops moving up and down. At this time, the pin 6 installed on the moving block 5 is inserted into the internal pin sleeve 7 installed in the upper slide plate 2. At this time, it is ensured that the upper slide plate push cylinder 3 on the upper slide plate 2 is connected to the upper slide plate 2. When the power system equipped with the large die forging hydraulic press provides power for the upper slide plate push cylinder 3, the plunger rod of the upper slide plate push cylinder 3 extends, driving the movement of the moving block 5. At this time, the moving block 5, the pin 6, and the internal pin sleeve 7 are all fixed together with the upper slide plate 2. Therefore, the movement of the upper slide plate 2 is realized. After completing one stroke of the upper slide plate push cylinder 3, the pin 6 retracts and separates from the internal pin sleeve 7. In this way, the upper slide plate push cylinder 3 is separated from the upper slide plate 2. When the pin retracts, the upper slide plate 2 will remain in its original position. At this time, the pin 6 installed on the moving block 5 will be inserted into the internal pin sleeve 7 installed inside the upper slide plate 2 again. At this time, the moving block 5 connected to the upper slide plate 2 by the upper slide plate push cylinder 3 is connected again. When the power system equipped with the large die forging hydraulic press provides power for the upper slide plate 2 and the upper slide plate push cylinder 3, the plunger rod of the upper slide plate push cylinder 3 extends, driving the movement of the moving block 5 again. At this time, the moving block 5, the pin 6, and the internal pin sleeve 7 are all fixed together with the upper slide plate 2, realizing the re-movement of the upper slide plate 2. Repeating this process, the long-stroke stepping of the upper slide plate 2 is realized.

[0030] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
