However, in the continuous bending process of general bending equipment, the sheet is placed into the machine manually by hand. Therefore, a lot of effort is required to observe the position of the hand during the processing to avoid the hand being caught in the bending machine. This results in low efficiency in the continuous bending process. At the same time, the operation is greatly affected by human operation, which can easily lead to large bending deviations in the same batch of materials. Utility Model Content

[0013] 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.

[0014] 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.

[0015] Combination Figures 1-4 The present invention relates to an electro-hydraulic bending device capable of continuous automatic bending, comprising a bending machine body 1, a slide rail 2 provided at the center of the worktable surface of the bending machine body 1, an operating column 3 slidably disposed on the worktable surface, support platforms 4 provided on both sides of the bottom of the operating column 3, rollers 5 provided on the outer side of the support platforms 4, the longitudinal section of the slide rail 2 being inverted "T" shaped, the rollers 5 slidably disposed on both sides of the bottom of the slide rail 2, a height adjustment mechanism provided inside the support platform 4, and an adsorption mechanism provided inside the height adjustment mechanism.

[0016] It should be noted that the operating column 3 and the roller 5 slide within the slide rail 2, thereby limiting the position of the operating column 3, while the roller 5 can reduce the friction of the operating column 3 during movement, thus facilitating the adjustment of the position of the operating column 3.

[0017] In this embodiment, a fixing frame 6 is provided at the lower side of the operating column 3, and a screw 7 is provided inside the fixing frame 6. The screw 7 is hollow inside, and a fixing cap 8 is threadedly connected inside the lower opening of the screw 7. A support rod 10 is slidably provided inside the screw 7.

[0018] In this embodiment, a ball bearing 11 is provided inside the lower end of the support rod 10, and a first spring 9 is provided inside the upper end of the screw 7, and the first spring 9 is in contact with the upper end of the support rod 10.

[0019] It should be noted that since the screw 7 and the fixed frame 6 are threadedly connected, the height of the screw 7 can be adjusted by rotating it. The fixed cap 8 can limit the first spring 9 and the support rod 10. When the screw 7 descends, the friction between the ball 11 and the table of the bending machine body 1 will also increase, thereby increasing the resistance of the operating column 3 when it moves.

[0020] In this embodiment, the height adjustment mechanism includes a worm gear 12, a worm wheel 13, a lead screw 14, and a first support frame 15. The worm gear 12 is rotatably disposed inside the side of the operating column 3. The worm wheel 13 is connected to the side of the worm gear 12. The lead screw 14 is disposed at the upper end of the worm wheel 13. The worm wheel 13 and the lead screw 14 are rotatably disposed inside the operating column 3. The first support frame 15 is threadedly connected to the outer side of the lead screw 14. The first support frame 15 is slidably disposed inside the operating column 3.

[0021] It should be noted that when the device is in use, the worm gear 12 is rotated to drive the worm wheel 13 to rotate. When the worm wheel 13 rotates, it will drive the lead screw 14 to rotate. The lead screw 14 is threadedly connected to the first support frame 15. The operating column 3 will limit the first support frame 15. Therefore, when the lead screw 14 rotates, the height of the first support frame 15 will be adjusted.

[0022] In this embodiment, the adsorption mechanism includes a second support frame 16, an air pump 21, and a second motor. The second motor is provided on the outer side of the second support frame 16 away from the operating column 3. The output end of the second motor is connected to the second support frame 16. The second support frame 16 is rotatably disposed inside the second support frame 16. The other end of the second support frame 16 is connected to the air pump 21.

[0023] It should be noted that the second motor will drive the second support frame 16 to rotate, thereby adjusting the angle of the second support frame 16.

[0024] In this embodiment, a suction cup 22 is provided on the side of the second support frame 16, and a control valve 17 is provided at the center of the suction cup 22. A fixing rod 18 is provided inside the control valve 17, and a limit rod 20 is slidably provided inside the fixing rod 18. A second spring 19 is provided on both sides of one end of the limit rod 20 inside the fixing rod 18. The lower end of the control valve 17 has a "V" shaped longitudinal section, and the lower end of the limit rod 20 fits against the minimum diameter of the lower end of the control valve 17.

[0025] It should be noted that the air pressure inside the suction cup 22 can be controlled by the air pump 21 to adsorb and fix the material, making it easier to move the material for bending. When the suction cup 22 is not adsorbing the material, as the air pump 21 works, the air pressure inside the tightly fitted suction cup 22 will gradually decrease. Then the second spring 19 will drive the limit rod 20 to move and block the control valve 17, thereby preventing the suction cup 22 from connecting with other areas, so that adsorption can still be performed inside the suction cup 22.

[0026] Working principle: First, the downward pressure of the ball bearing 11 is adjusted by rotating the screw 7, thereby adjusting the resistance when the operating column 3 moves. Then, the material is attached to the suction cup 22, and the air pump 21 works to generate negative pressure in the suction cup 22 to fix the material. Then, the angle between the second support frame 16 and the material is adjusted by operating the second motor. At the same time, the worm gear 12 of the same specification is rotated to drive the worm wheel 13 and the lead screw 14 to rotate, thereby adjusting the height of the first support frame 15 and the material. Finally, the bending machine body 1 performs the bending operation.

[0027] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
