Description

Technical Field

[0001] This utility model belongs to the technical field of beam bending fixtures, specifically relating to a beam bending fixture. Background Technology

[0002] Beam bending fixtures are specialized equipment or devices used for the precise bending of metal beams. Their design must balance precision, efficiency, and versatility to meet the processing needs of beams of different shapes and sizes. The technological evolution of beam bending fixtures is shifting from "single-function" to "composite intelligence," with their core competitiveness lying in the deep matching of material properties, process parameters, and equipment rigidity. Enterprises need to select fixture platforms with open interfaces and scalability, based on their own product portfolio, to address the market trend of multi-variety, small-batch production.

[0003] Currently, existing beam bending fixtures typically require workers to measure and mark the bending positions before bending. However, traditional beam bending fixtures often require manual measurement of bending positions, and subsequent bending of beams in the same batch requires marking each beam to be bent, which takes a lot of time and reduces the efficiency of beam bending. Utility Model Content

[0004] The purpose of this utility model is to provide a beam bending fixture, which aims to solve the problem that existing beam bending fixtures usually require workers to measure and mark the bending position before bending. However, traditional beam bending fixtures often require manual measurement of the bending position, and each beam in the same batch needs to be marked, which takes a lot of time and reduces the efficiency of beam bending.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a beam bending fixture, comprising two support frames, a top plate fixedly connected to the top of the two support frames, a hydraulic cylinder installed at the bottom of the top plate, a bending cutter connected to the output end of the hydraulic cylinder, and a bending cutter holder installed between the two support frames;

[0006] A first guide rod is fixedly connected to the bottom of the top plate. A worktable is movably connected between the two support frames. A lead screw passes through the outer wall of the worktable. A threaded connecting sleeve is threaded onto the outer wall of the lead screw. A connecting block is fixedly connected to the top of the threaded connecting sleeve. A limit plate is fixedly connected to one end of the connecting block. A scale is provided on the top of the worktable. A connecting rod is fixedly connected to the outer wall of the threaded connecting sleeve. A second guide rod is fixedly connected to the inside of the worktable. An adjustment knob is fixedly connected to one end of the lead screw.

[0007] In a preferred embodiment of the beam bending fixture of this utility model, the limiting plate is located at the top of the scale.

[0008] As a preferred embodiment of the beam bending fixture of this utility model, the through end of the lead screw is connected to the inner wall of the worktable via a bearing to form a rotating connection structure.

[0009] As a preferred embodiment of the beam bending fixture of this utility model, the end of the connecting rod away from the threaded connecting sleeve is sleeved on the outer wall of the second guide rod.

[0010] As a preferred embodiment of the beam bending fixture of this utility model, the limiting plate is fitted to the top of the workbench.

[0011] As a preferred embodiment of the beam bending fixture of this utility model, positioning blocks are fixedly connected to the outer walls of both sides of the workbench, and positioning grooves are opened on the outer walls of the two support frames.

[0012] As a preferred embodiment of the beam bending fixture of this utility model, the dimensions of the positioning block and the positioning groove are adapted to each other.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By adjusting the knob to rotate the lead screw, the threaded connecting sleeve connected to its outer wall can move along the second guide rod under the action of the connecting rod.

Detailed Implementation

[0022] 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.

[0023] Please see Figures 1-4 The present invention provides the following technical solution: a beam bending fixture, comprising two support frames 1, a top plate 2 fixedly connected to the top of the two support frames 1, a hydraulic cylinder 3 installed at the bottom of the top plate 2, a bending cutter 4 connected to the output end of the hydraulic cylinder 3, and a bending cutter seat 5 installed between the two support frames 1.

[0024] The bottom of the top plate 2 is fixedly connected to a first guide rod 6. A worktable 7 is movably connected between the two support frames 1. A lead screw 8 passes through the outer wall of the worktable 7. A threaded connecting sleeve 9 is threadedly connected to the outer wall of the lead screw 8. A connecting block 10 is fixedly connected to the top of the threaded connecting sleeve 9. A limit plate 11 is fixedly connected to one end of the connecting block 10. A scale 12 is provided on the top of the worktable 7. A connecting rod 13 is fixedly connected to the outer wall of the threaded connecting sleeve 9. A second guide rod 14 is fixedly connected inside the worktable 7. An adjustment knob 15 is fixedly connected to one end of the lead screw 8.

[0025] Preferably, the limiting plate 11 is located at the top of the scale 12, the through end of the lead screw 8 forms a rotating connection structure with the inner wall of the worktable 7 through the bearing, the end of the connecting rod 13 away from the threaded connecting sleeve 9 is sleeved on the outer wall of the second guide rod 14, and the limiting plate 11 is in contact with the top of the worktable 7.

[0026] In practical use, by adjusting the knob 15 to rotate the lead screw 8, the threaded connecting sleeve 9 connected to the outer wall can move along the second guide rod 14 under the action of the connecting rod 13. As the threaded connecting sleeve 9 moves, one end of the connecting block 10 connected to its top will drive the limiting plate 11 to move along the scale 12. Then, according to the bending position, the limiting plate 11 is stopped at the designated position. Then, by pressing one end of the crossbeam against the limiting plate 11, the hydraulic cylinder 3 can be activated to press down and bend, thereby reducing the workload and improving the bending efficiency.

[0027] Preferably, positioning blocks 16 are fixedly connected to the outer walls on both sides of the workbench 7, and positioning grooves 17 are opened on the outer walls of the two support frames 1, with the dimensions of the positioning blocks 16 and the positioning grooves 17 being compatible.

[0028] In practical use, by setting the positioning blocks 16 and positioning grooves 17, when assembling the crossbeam bending fixture, the positioning blocks 16 on both sides of the workbench 7 are embedded into the positioning grooves 17 on the support frame 1, so that the workbench 7 can be conveniently placed between the two support frames 1, and it is also very convenient to disassemble.

[0029] Working principle: First, with the positioning blocks 16 and positioning grooves 17, when assembling the beam bending fixture, the positioning blocks 16 on both sides of the worktable 7 are embedded into the positioning grooves 17 on the support frame 1, allowing the worktable 7 to be conveniently placed between the two support frames 1. Then, the operator simply needs to gently hold the adjustment knob 15 and rotate it in the appropriate direction. As the adjustment knob 15 rotates, the lead screw 8 connected to it will also rotate synchronously. The outer wall of the lead screw 8 is machined with precision threads, and the inner wall of the threaded connecting sleeve 9 is also provided with matching threads, and the two are tightly connected through the threads. When the lead screw 8 rotates, according to the principle of thread transmission, the threaded connecting sleeve 9 will move on the lead screw 8. However, the movement of the threaded connecting sleeve 9 is not arbitrary; it is constrained by the connecting rod 13 and the second guide rod 14. One end of the connecting rod 13 is firmly connected to the threaded connecting sleeve 9, and the other end is connected to the sliding part on the second guide rod 14. The second guide rod 14 acts like a precise track, providing stable and accurate guidance for the movement of the threaded connecting sleeve 9. Thus, when the lead screw 8 rotates, the threaded connecting sleeve 9 moves smoothly along the second guide rod 14 under the influence of the connecting rod 13. As the threaded connecting sleeve 9 moves, the connecting block 10 at its top also moves. One end of the connecting block 10 is tightly connected to the limiting plate 11, so when the connecting block 10 moves, it drives the limiting plate 11 to move as well. A scale 12 is located below the limiting plate 11, clearly marked with graduations, like a precise ruler, providing a clear positional reference for the movement of the limiting plate 11. The operator can observe the graduations on the scale 12 while rotating the adjustment knob 15 to precisely move the limiting plate 11 along the top of the scale 12. Before bending, the operator needs to carefully adjust the position of the limiting plate 11 by rotating the adjusting knob 15 according to the bending position requirements of the crossbeam, so that the limiting plate 11 accurately stops at the specified scale position. This specified position is the precise position required for bending the crossbeam. After the limiting plate 11 is adjusted to the correct position, the operator moves the crossbeam to be bent and firmly places one end of the crossbeam against the limiting plate 11. At this point, the position of the crossbeam is accurately determined. Next, the operator only needs to press the control button to start the hydraulic cylinder 3. The hydraulic cylinder 3 starts working, and its piston rod gradually presses down, applying strong pressure to the crossbeam, thereby realizing the bending operation of the crossbeam.

[0030] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
