Through the setting adjustment component, by starting the servo motor to drive the threaded rod to rotate, the adjustment frame slides and drives the base plate to descend, so that the overall height of the base changes, which is convenient for workers at different heights to work more comfortably and improves its applicability. At the same time, after the base height adjustment is completed, the support rod and other items are placed between the bottom end of the base and the top end of the base plate to further improve the overall pressure-bearing stability after adjustment, avoiding the traditional need to externally hang the entire hydraulic press height and then select different support bases, which makes the overall process complicated. It does not require external hanging equipment to achieve overall height adjustment. At the same time, when some smaller hydraulic pressures are required, there is no need to use support rods for support, which improves its practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1

[0030] The preferred embodiment of the automatic hydraulic press for pallet production provided by the present invention is as follows: Figures 1 to 5 As shown: an automatic hydraulic press for pallet production, including a base 5; an adjustment component 6 assembled inside the base 5, the adjustment component 6 can be used to adjust the overall height of the base 5; a workbench 7 fixedly connected to the middle position of the top of the base 5; a vertical rod 4 fixedly connected to the four corners of the top of the base 5; a top cover 2 fixedly connected to the top of the vertical rod 4; a hydraulic cylinder 1 fixedly connected to the middle position of the top of the top cover 2; an upper pressure plate 8 slidably connected to the surface of the vertical rod 4, the top of the upper pressure plate 8 is fixedly connected to the output end of the hydraulic cylinder 1; a protective component 3 assembled around the upper pressure plate 8, the protective component 3 prevents the workpiece from being broken by force and causing splashing and other safety hazards.

[0031] The protective component 3 includes: a protective cover 301 movably connected to the periphery of the upper pressure plate 8; reserved grooves 304 opened on both sides of the inner wall of the protective cover 301; a sliding rod 305 fixedly connected to the inner wall of the reserved groove 304; a sliding block 306 slidably connected to the surface of the sliding rod 305; a fixed spring 307 wrapped around the surface of the sliding rod 305, and the two ends of the fixed spring 307 are respectively fixedly connected to the top wall of the reserved groove 304 and the bottom end of the sliding block 306; and a connecting plate 303 fixedly connected to one side of the sliding block 306.

[0032] It should be noted that some existing automatic hydraulic presses for pallet production still have certain shortcomings in actual use. During the actual hydraulic processing process, the workpiece may be broken or even splashed due to the high pressure. The splashed workpiece may cause collision damage to the peripheral equipment of the hydraulic press or splash to the workers, causing safety hazards and making it inconvenient to use.

[0033] In this embodiment, the overall height of the base 5 is changed by adjusting the assembly 6, so that it can be used for workers of different heights, and items such as support rods can be placed between the bottom end of the base 5 and the top end of the bottom plate 602, further improving the overall pressure-bearing stability after adjustment, avoiding the limitation of the traditional hydraulic press body that needs to be raised as a whole for adjustment. Then, the lower mold and the upper die are fixed to the top end of the workbench 7 and the bottom end of the upper pressing plate 8 respectively, and then the protective cover 301 is inserted into the vertical rod 4 from top to bottom, and the fixing bolts 308 and the threads inside the bolt holes 302 are used to achieve a firm installation between the connecting plate 303 and the upper pressing plate 8, and then the workpiece is placed on the lower mold.

Then the upper pressure plate 8 continues to descend. The reaction force of the bottom end of the protective cover 301 contacting the top of the base 5 will cause the sliding block 306 to slide on the surface of the slide rod 305 and compress the sliding block 306. Then, during the entire hydraulic process, the protective cover 301 can be used to shield and protect the periphery of the workbench 7 to avoid safety hazards caused by excessive force on the workpiece, such as breakage or splashing. After the upper pressure plate 8 rises, the elastic force of the fixed spring 307 can be used to restore the protective cover 301 to its original position.

[0035] In this embodiment, the threaded fit between the fixing bolt 308 and the bolt hole 302 facilitates the overall disassembly of the protective assembly 3, thereby facilitating the disassembly and replacement of the upper die and the bottom end of the upper pressing plate 8.

[0036] In a further preferred embodiment of the present invention, friction lines 309 are provided at equal angles on the upper end of the surface of the fixing bolt 308 , and the friction lines 309 are used to increase the anti-slip stability of the rotation between the operator's fingers and the nut on the upper end of the fixing bolt 308 .

[0038] In this embodiment, a relatively high U-shaped protective cover 301 is used to fully shield and protect the workpiece on the lower mold.

[0039] In a further preferred embodiment of the present invention, the cross-section of the connecting plate 303 is in an inverted L-shape, and the lower end of one side of the connecting plate 303 and one side of the sliding block 306 are welded to form an integrated structure.

[0040] In this embodiment, an inverted L-shaped connecting plate 303 is used to facilitate close fixation between the connecting plate 303 and the top end of the upper pressing plate 8 .

[0041] In a further preferred embodiment of the present invention, a sliding structure is formed between the sliding block 306 and the inside of the reserved groove 304 , and the shape of the reserved groove 304 and the sliding block 306 in a top view is convex.
