Description

Technical Field

[0001] This utility model relates to the field of forklift rack processing technology, specifically a hydraulic bending machine for U-shaped parts of forklift racks. Background Technology

[0002] A hydraulic bending machine for forklift rack U-shaped components is a device used to bend metal wire or pipe into a U-shape, specifically for manufacturing U-shaped components for forklift racks. It is typically powered by a hydraulic system, where an oil pump delivers hydraulic oil to various hydraulic cylinders, generating pressure to drive pistons, which in turn move the bending die to bend the workpiece. The control system precisely controls the pressure, flow, and direction of the hydraulic system to achieve accurate control of the bending angle, speed, and force, ensuring the dimensional accuracy and quality of the bent frame.

[0003] The aforementioned bending structure involves fixing one end of a metal strip and then bending the metal strip. However, during the bending process, a tensile force is generated on the fixed side. If the metal strip is not securely fixed, it may detach from the fixing device, causing bending errors. If the metal strip is fixed too securely, it may be damaged. Utility Model Content

[0004] The purpose of this utility model is to provide a hydraulic bending machine for U-shaped parts of forklift racks to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic bending machine for U-shaped parts of forklift racks, comprising a placement box, a connecting plate fixedly connected to one side of the placement box, two sets of sliding grooves inside the connecting plate, a second lug slidably connected inside the sliding groove, a moving plate fixedly connected to the upper part of the second lug, a rotating plate rotatably connected inside the moving plate at the end away from the placement box, a hydraulic turning machine fixedly connected to the outer side of the moving plate, the power end of the hydraulic turning machine fixedly connected to the rotating plate, side plates fixedly connected to both sides of the moving plate, connecting pieces fixedly connected to the upper sides of the side plates, a first threaded rod rotatably connected between the two sets of connecting pieces on the front side, a first sliding rod fixedly connected between the two sets of connecting pieces on the rear side, a first front lug threaded to the outer side of the first threaded rod, a first rear lug slidably connected to the outer side of the first sliding rod, an outer mounting frame fixedly connected between the first lugs on both sides, a second hydraulic cylinder fixedly connected to the upper part of the outer mounting frame, an inner mounting frame fixedly connected through the power end of the second hydraulic cylinder, and a pressure roller rotatably connected inside the inner mounting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model places a metal strip in a placement box. A first hydraulic cylinder drives a top plate to press against one side of the metal strip, and a second hydraulic cylinder drives an inner mounting bracket to move downward, so that a pressure roller presses against the upper surface of the metal strip to fix the metal strip. A hydraulic turning machine drives a rotating plate to rotate and bend the metal strip. When one side of the metal strip is bent, it can be effectively fixed. By applying a pushing force to the fixed side of the metal strip during bending, it prevents the metal strip from moving during bending and causing inaccurate bending position.

[0019] 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.

[0020] Please see Figure 1-3This utility model provides a technical solution: a hydraulic bending machine for U-shaped parts of forklift racks, including a placement box 1, a connecting plate 2 fixedly welded to one side of the placement box 1, two sets of sliding grooves 5 inside the connecting plate 2, a second lug 6 slidably installed inside the sliding groove 5, a movable plate 7 fixedly welded to the upper part of the second lug 6, a rotating plate 8 rotatably installed inside the end of the movable plate 7 away from the placement box 1, a hydraulic turning machine 9 threadedly installed on the outer side of the movable plate 7, the power end of the hydraulic turning machine 9 threadedly connected to the rotating plate 8, side plates 10 fixedly welded to both sides of the movable plate 7, connecting pieces 11 fixedly welded to the upper two sides of the side plates 10, a first threaded rod 12 rotatably installed between the two sets of connecting pieces 11 on the front side, a first sliding rod 13 fixedly welded between the two sets of connecting pieces 11 on the rear side, a front first lug 14 threadedly installed on the outer side of the first threaded rod 12, a rear first lug 14 slidably installed on the outer side of the first sliding rod 13, and the second threaded rod 12 threadedly ... An outer mounting bracket 15 is fixedly welded between the lugs 14. A second hydraulic cylinder 16 is threaded onto the upper part of the outer mounting bracket 15. The power end of the second hydraulic cylinder 16 penetrates the outer mounting bracket 15 and is threaded onto an inner mounting bracket 17. A pressure roller 18 is rotatably mounted inside the inner mounting bracket 17. By placing the initial metal strip of the baffle on the placement box 1, and by moving the second lug 6 along the sliding groove 5, the position of the moving plate 7 is changed so that one end of the rotating plate 8 is directly facing the part of the metal strip that needs to be bent. The second hydraulic cylinder 16 drives the inner mounting bracket 17 to move downward, so that the pressure roller 18 presses against the upper surface of the metal strip, fixes the metal strip, and ensures that the bending part of the metal strip has a certain curvature. The hydraulic turning machine 9 drives the rotating plate 8 to rotate, performs bending processing on the metal strip, and drives the first lug 14 to move along the first sliding rod 13 by rotating the first threaded rod 12, thereby changing the distance between the pressure roller 18 and the rotating plate 8 according to the different thicknesses of the metal strip.

[0021] Two sets of mounting plates 21 are fixedly welded to the lower part of the placement box 1. A second threaded rod 23 is rotatably mounted between the front sides of the mounting plates 21. The second threaded rod 23 is threaded into the inside of the second lug 6. A motor 22 is mounted on the outer flange of one side of the mounting plate 21. The power end of the motor 22 is connected to one end of the second threaded rod 23 by a coupling. A second sliding rod 24 is fixedly welded between the rear sides of the mounting plates 21. The second sliding rod 24 is slidably mounted inside the second lug 6. The motor 22 drives the second threaded rod 23, causing the second lug 6 to move along the second sliding rod 24, thereby adjusting the moving position of the moving plate 7.

[0022] The upper surface of the placement box 1 is flush with the upper surface of the movable plate 7, ensuring that the metal strip is placed horizontally on the upper part of the placement box 1 and the movable plate 7;

[0023] The placement box 1 has lifting grooves 25 on both sides. Lifting blocks 26 are slidably installed inside the lifting grooves 25. A fixed frame 29 is fixedly welded between the two lifting blocks 26. Two sets of positioning rollers 30 are rotatably installed inside the fixed frame 29. When the barrier is bent on one side and continues to bend on the other side, the bent part of the metal strip is inserted into the lower part of the lower positioning roller 30. The positioning roller 30 is at the bent part, and the upper positioning roller 30 abuts against the bent metal strip, thereby fixing one side of the bent metal strip and preventing the bent part of the metal strip from deforming when bending the other side.

[0024] A third threaded rod 27 is rotatably installed inside the front lifting groove 25. The third threaded rod 27 is threaded inside the front lifting block 26. A third sliding rod 28 is fixedly welded inside the rear lifting groove 25. The third sliding rod 28 is slidably installed inside the rear lifting block 26. By rotating the third threaded rod 27, the lifting block 26 is driven to move up and down along the third sliding rod 28, thereby changing the distance between the lower positioning roller 30 and the placement box 1 according to the thickness of the metal strip. The metal strip can be easily inserted by moving the positioning roller 30 upward.

[0025] A first hydraulic cylinder 3 is installed on the flange on the side of the placement box 1 away from the moving plate 7. The power end of the first hydraulic cylinder 3 is threaded through the placement box 1 and a top plate 4 is installed. The first hydraulic cylinder 3 drives the top plate 4 to move. When the metal strip bends for the first time, the top plate 4 holds one end of the metal strip, thereby preventing the metal strip from moving away from the rotating plate 8 when the rotating plate 8 bends. When the other end of the metal strip bends, the top plate 4, together with the positioning roller 30, holds both sides of the bent part of the metal strip, which can prevent the metal strip from moving while ensuring that the bent part of the metal strip does not deform.

[0026] The box 1 has limiting grooves 19 on both sides, and limiting blocks 20 are fixedly welded to both sides of the top plate 4. The limiting blocks 20 are slidably installed inside the limiting grooves 19 to ensure that the two ends of the top plate 4 are balanced and that the side of the metal strip closest to the top plate 4 remains horizontal.

[0027] Working principle: In use, the metal strip is placed in the placement box 1. The first hydraulic cylinder 3 drives the top plate 4 to press against one side of the metal strip. The motor 22 drives the second threaded rod 23, which in turn moves the second lug 6 along the second sliding rod 24, thereby adjusting the position of the moving plate 7 so that one end of the rotating plate 8 is aligned with the part of the metal strip that needs to be bent. The second hydraulic cylinder 16 drives the inner mounting bracket 17 to move downward, causing the pressure roller 18 to press against the upper surface of the metal strip, fixing the metal strip and ensuring that the bent part of the metal strip has a certain curvature. The hydraulic turning machine 9 drives the rotating plate 8 to rotate. The metal strip is bent. After one side of the metal strip is bent, the bent end is passed through the positioning roller 30. By rotating the third threaded rod 27, the lifting block 26 is driven to move up and down along the third sliding rod 28, so that the lower positioning roller 30 presses the bent part. The first hydraulic cylinder 3 drives the top plate 4 to abut against one side of the metal strip. The top plate 4, together with the positioning roller 30, abuts against both sides of the bent part of the metal strip, which can prevent the metal strip from moving while ensuring that the bent part of the metal strip does not deform. By adjusting the moving plate 7, the rotating plate 8 bends the other side of the metal strip, realizing the bending work of the U-shaped frame.
