Technical Field
[0001] The utility model relates to the technical field of bending machines, in particular to a device for preventing eccentric loading of the slider of a bending machine. Background Art
[0002] A bending machine is a machine that can bend thin plates. However, during the debugging and operation of the bending machine, when the speeds of the oil cylinders on the left and right sides are inconsistent, the slider will have an eccentric loading situation on the left and right. In severe cases, it can cause the suspension bolts at the connection between the oil cylinder and the slider to break, and at the same time, there is also a risk of the slider falling. This will not only damage the bending machine but also pose certain safety hazards.
[0003] When an eccentric loading situation occurs, at present, it can be adjusted manually, but it needs to be repeatedly adjusted to compensate for the eccentric loading, which increases labor costs and wastes time.
[0004] Therefore, the utility model provides a device for preventing eccentric loading of the slider of a bending machine, which can effectively solve the problem of eccentric loading on both sides of the slider, greatly improve the service life of the machine and reduce safety hazards, and improve production efficiency. Content of the Utility Model
[0005] The purpose of the utility model is to solve the problems existing in the prior art, and provide a device for preventing eccentric loading of the slider of a bending machine.
[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0007] A device for preventing eccentric loading of the slider of a bending machine includes a bending machine body, the bending machine body includes a frame, a bending machine slider, and an oil cylinder. The oil cylinders are symmetrically and fixedly arranged on both sides of the bending machine slider, the frames are symmetrically arranged behind the bending machine slider, and an anti-eccentric loading device is arranged between the two groups of frames. The anti-eccentric loading device includes a sliding plate, a guiding plate, an adjusting plate group, and a mounting bracket for mounting the anti-eccentric loading device.
[0008] Further, the mounting bracket is L-shaped, the short side of the mounting bracket is fixedly installed on the bending machine slider, and the inner short side of the mounting bracket is fixedly connected with the sliding plate.
[0009] Further, the adjusting plate group includes a first adjusting plate, a second adjusting plate, and an adjusting pressing plate. The second adjusting plate is movably connected to the guiding plate, the first adjusting plate is movably connected to the adjusting pressing plate, and the adjusting pressing plate is fixedly connected to the end of the long side of the mounting bracket.
[0010] Further, the sliding plate, the guiding plate, the first adjusting plate, and the second adjusting plate are in contact in sequence, and the sliding plate, the guiding plate, the first adjusting plate, and the second adjusting plate enclose a square.
[0011] Furthermore, the contact surfaces between the sliding plate and the guiding plate and the second adjusting plate are inclined surface contacts, and the contact surfaces between the first adjusting plate and the guiding plate and the second adjusting plate are inclined surface contacts.
[0012] Furthermore, the sliding plate slides between the second adjusting plate and the guiding plate, and the first adjusting plate slides between the second adjusting plate and the guiding plate.
[0013] Furthermore, the second adjusting plate is connected to the guiding plate through an adjustable bolt, and the first adjusting plate is connected to the adjusting pressing plate through an adjustable bolt.
[0014] Compared with the existing technology, a device for preventing the eccentric load of the slider of a bending machine provided by the present utility model adopts a simple mechanical structure.

At the same time, the terms "first", "second", etc. are only used to distinguish the names of the components, and there is no primary and secondary relationship, and therefore cannot be construed as a limitation of the present utility model.
[0029] Embodiment 1, as Figure 1 , Figure 2 , Figure 5 and Figure 6 shown, a device for preventing the offset load of the slider of a bending machine, including a bending machine body, the bending machine body includes a frame 1, a bending machine slider 2, and an oil cylinder. The oil cylinders are symmetrically and fixedly arranged on both sides of the bending machine slider 2, and the frames 1 are symmetrically arranged behind the bending machine slider 2. An anti-offset load device is arranged between the two groups of frames 1 and the bending machine slider 2. The anti-offset load device includes a sliding plate 3, a guide plate 4, an adjusting plate group, and a mounting bracket 8 for mounting the anti-offset load device.
[0030] Through the setting of the above solution, the anti-offset load device restricts the offset load direction of the bending machine slider 2, allowing the bending machine slider 2 to only move up and down, and the bending machine slider 2 cannot have an offset load situation.
[0031] Embodiment 2, as Figure 4 and Figure 6As shown, the mounting bracket 8 is L-shaped. The short side of the mounting bracket 8 is fixedly installed on the slider 2 of the bending machine by bolts, and a sliding plate 3 is fixedly connected to the inner short side of the mounting bracket 8. When the slider slides up and down, it can drive the mounting bracket 8 and the sliding plate 3 to slide up and down.
[0032] The adjusting plate group includes a first adjusting plate 5, a second adjusting plate 6 and an adjusting pressing plate 7. The second adjusting plate 6 is movably connected to the guiding plate 4, the first adjusting plate 5 is movably connected to the adjusting pressing plate 7, and the adjusting pressing plate 7 is fixedly connected to the end of the long side of the mounting bracket 8.
[0033] The second adjusting plate 6 is movably connected to the guiding plate 4 by bolts. By rotating the bolts, the second adjusting plate 6 can be moved left and right ( Figure 4 in the direction shown), the first adjusting plate 5 is movably connected to the adjusting pressing plate 7 by bolts. By adjusting the bolts on the adjusting pressing plate 7, the first adjusting plate 5 can be moved in the direction of approaching or departing from the slider ( Figure 4 in the direction shown).
[0034] Example 3, as Figure 4 shown, the sliding plate 3, the guiding plate 4, the first adjusting plate 5 and the second adjusting plate 6 are in contact in sequence, and the sliding plate 3, the guiding plate 4, the first adjusting plate 5 and the second adjusting plate 6 enclose a square.
[0035] The contact surfaces between the sliding plate 3 and the guiding plate 4 and the second adjusting plate 6 are inclined surface contacts, and the contact surfaces between the first adjusting plate 5 and the guiding plate 4 and the second adjusting plate 6 are inclined surface contacts.
[0036] The sliding plate 3 slides between the second adjusting plate 6 and the guiding plate 4, and the first adjusting plate 5 slides between the second adjusting plate 6 and the guiding plate 4.
[0037] In this embodiment, the sliding plate 3, the guiding plate 4, the first adjusting plate 5 and the second adjusting plate 6 are all set as hexagons, and two surfaces are inclined surfaces. Therefore, the inclined surfaces on both sides of the sliding plate 3 are respectively in contact with the inclined surfaces of the guiding plate 4 and the second adjusting plate 6, and the two inclined surfaces of the first adjusting plate 5 are respectively in contact with the inclined surfaces of the guiding plate 4 and the second adjusting plate 6.
[0038] By further adjusting the bolts on the second adjusting plate 6 and the adjusting pressing plate 7, the positions of the first adjusting plate 5 and the second adjusting plate 6 can be adjusted, and further, the position of the slider 2 of the bending machine can be fixed, so that the slider 2 of the bending machine cannot be eccentrically loaded.
[0039] Referring to Figure 3 , by using two sets of anti-eccentric loading devices, the front and rear offsets of the slider 2 of the bending machine during operation are restricted, and the slider 2 of the bending machine can only slide up and down.
[0040] During use, according to the actual situation, adjust the bolts of the adjusting pressing plate 7 and the bolts of the second adjusting plate 6 for the contact gaps between the sliding plate 3, the guiding plate 4, the first adjusting plate 5, and the second adjusting plate 6. The adjusted contact gap can be a tight fit or have a certain gap. In this embodiment, the contact gap is 0.01 mm.
[0041] During the sliding of the bending machine slider 2, the guiding plate 4 and the second adjusting plate 6 are fixed and act as guide rails. The sliding plate 3 and the first adjusting plate 5 move up and down with the bending machine slider 2. The sliding plate 3, the guiding plate 4, the first adjusting plate 5, and the second adjusting plate 6 jointly restrict the eccentric load of the slider.
[0042] Through the adjusted use of the anti-eccentric load device, when the bending machine slider 2 moves up and down, it can only move up and down along the guiding plate 4 and the second adjusting plate 6, ensuring that the slider can move along the established trajectory. Therefore, the probability of the bending machine slider 2 having an eccentric load situation is small, ensuring the bending accuracy of the workpiece.
[0043] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
