[0001] This utility model relates to the field of electro-hydraulic bending machine technology, and more specifically, to an anti-eccentric load device for the slider of an electro-hydraulic bending machine. Background Technology

[0002] In actual use, electro-hydraulic bending machines are prone to eccentric loads on the slider due to asymmetrical workpiece shapes and uneven bending position distribution. This can lead to problems such as slider tilting, accelerated die wear, and decreased processing accuracy, and in severe cases, even affect the service life and safety of the equipment. Current technologies lack effective anti-eccentric load structures for the slider, making it impossible to achieve rapid response and automatic adjustment functions. Utility Model Content

The output end of the telescopic frame is connected to the movable sleeve, and a translation block is provided inside the movable sleeve.

[0006] Preferably, the movable sleeve has a hollow internal structure, and movable holes matching the limiting rod are provided on the upper and lower sides of the movable sleeve.

[0007] Preferably, the upper and lower surfaces of the translation block are inclined surfaces in the same direction. The limiting rod has a groove that matches the translation block. The translation block engages with the groove. Extension rods are provided on both sides of the translation block. The extension rods pass through the movable sleeve. The movable sleeve has a limiting hole that matches the extension rod. The limiting hole controls the movement path of the extension rod, so that the translation block can only move horizontally.

[0008] Preferably, the end of the extension rod located outside the movable sleeve is provided with a contact block, the surface of the contact block is provided with an elastic pad, the elastic pad is embedded with a pressure sensor, and the elastic pad is in contact with the inner wall of the reference guide groove.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0020] Combination Figures 1-4 The present invention relates to an anti-eccentric load device for an electro-hydraulic bending machine slider, comprising a slider body 1 and a guide rail assembly 2. A limit rod 11 is symmetrically arranged on the side of the slider body 1 near the guide rail assembly 2. An anti-eccentric load assembly 3 is sleeved on the limit rod 11 and is movably connected to the guide rail assembly 2.

[0021] Specifically, the guide rail assembly 2 includes a reference guide rail groove 21, a guide rail body 22, and adjusting wedges 23. The reference guide rail groove 21 is fixedly connected to the frame of the electro-hydraulic bending machine, and an electro-hydraulic cylinder mounting plate is provided at the upper end of the reference guide rail groove 21. An electro-hydraulic cylinder connected to the slider body 1 is provided on the electro-hydraulic cylinder mounting plate. The electro-hydraulic cylinder controls the slider body 1 to move up and down. The guide rail body 22 is fixedly connected to the middle position of the inner wall of the reference guide rail groove 21. Adjusting wedges 23 are provided in the reference guide rail groove 21 on both sides of the guide rail body 22. The adjusting wedges 23 are connected to the reference guide rail groove 21 by screws. The adjusting screws can drive the adjusting wedges 23 to move. The position of the anti-eccentric load assembly 3 can be adjusted by the two adjusting wedges 23, pushing the anti-eccentric load assembly 3 to move towards the middle and restricting the slider body 1 from shifting to both sides.

[0022] More specifically, the anti-eccentric load assembly 3 includes a movable sleeve 31, a translation block 32, and a telescopic frame 33. The movable sleeve 31 has a hollow internal structure, and movable holes 311 matching the limiting rod 11 are opened on the upper and lower sides of the movable sleeve 31. The limiting rod 11 passes through the movable holes 311, restricting the movable sleeve 31 to move up and down only along the limiting rod 11. At the same time, the output end of the telescopic frame 33 is connected to the movable sleeve 31, and the telescopic frame 33 pushes the movable sleeve 31 to move up and down. The translation block 32 is placed inside the movable sleeve 31, and the upper and lower surfaces of the translation block 32 are inclined in the same direction. The limiting rod 11 has a groove 111 matching the translation block 32, and the translation block 32 engages with the groove 111. In addition, extension rods 321 are provided on both sides of the translation block 32, and the extension rods 321 pass through the movable sleeve 31. The movable sleeve 31 has a limiting hole 311 matching the extension rod 321. 12. The limiting hole 312 controls the movement path of the extension rod 321, so that the translation block 32 can only move horizontally. The end of the extension rod 321 located outside the movable sleeve 31 is provided with a contact block 322. The surface of the contact block 322 is provided with an elastic pad 323. The elastic pad 323 is embedded with a pressure sensor. The elastic pad 323 is in contact with the inner wall of the reference guide groove 21. When the internal pressure sensor detects that the pressure on both sides of the translation block 32 is asymmetrical, the system sends a working command to the telescopic frame 33. The telescopic frame 33 is an electric telescopic rod. The telescopic frame 33 extends or shortens, which drives the movable sleeve 31 connected to it to move up or down. The movable sleeve 31 pushes the extension rod 321. The extension rod 321 moves horizontally, which drives the contact block 322 on the side with excessive pressure to move towards the movable sleeve 31, reducing the pressure on the reference guide groove 21, balancing the pressure on both sides of the movable sleeve 31, and preventing uneven load.

[0023] It should be noted that the movable sleeve 31 is provided with a groove that matches the guide rail body 22. The slider body 1 is connected to the guide rail body 22 through the movable sleeve 31. The movable sleeve 31 on both sides of the groove is provided with a pushing inclined surface 313. The pushing inclined surface 313 fits with the adjusting wedge 23. The offset of the movable sleeve 31 and the slider body 1 is adjusted by the pushing inclined surface 313 and the adjusting wedge 23.

[0024] Working process: When the electro-hydraulic cylinder drives the slider body 1 to move up and down for bending operations, the limiting rods 11 on both sides of the slider body 1 drive the anti-eccentric load assembly 3 connected to them to move synchronously. During the operation of the slider body 1, if the slider body 1 experiences uneven force due to the asymmetrical shape of the workpiece or uneven distribution of the bending position, the pressure sensor embedded in the elastic pad 323 installed on the contact block 322 will detect the pressure difference on both sides of the translation block 32. At this time, the system will send a control signal to the telescopic frame 33 according to the pressure difference to start its extension or retraction action. The telescopic frame 33 drives the movable sleeve 31 to move up or down, thereby pushing... The extension rod 321 of the translation block 32 allows the translation block 32 to move horizontally within the movable sleeve 31 along the direction limited by the limiting hole 312. The contact block 322 on the side with greater pressure is thus pulled back to a position close to the movable sleeve 31, reducing the pressure on the reference guide groove 21 on that side. This achieves dynamic balance of forces on both sides of the slider and prevents off-center loading. The two adjusting wedges 23 in the guide assembly 2 can be finely adjusted by screws. The adjusting wedges 23 fit against the pushing inclined surface 313 on the movable sleeve 31, which can push the movable sleeve 31 to move towards the center, further limiting the lateral displacement of the slider body 1 and improving the overall guiding accuracy and stability.
