Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, specifically a positioning machine for a steel plate bending machine with laser calibration. Background Technology

[0002] Laser-calibrated steel plate bending machines are devices that combine laser positioning technology with CNC bending processes. They are mainly used for high-precision metal plate forming. Their core function is to achieve precise workpiece positioning through a laser system and to complete complex shape processing in conjunction with the bending machine.

[0003] In existing technologies, such as laser alignment devices for bending machines, laser emitters are placed at both ends of the bending machine so that the laser beam is aligned with the center lines of the upper and lower dies of the bending machine. In use, the laser emitter emits a beam relative to the bending machine along the center of the bending die. The beam direction is calibrated so that the two opposing beams and the center line of the bending die are aligned. The worker places the steel plate on the lower die so that the bending point of the steel plate coincides with the laser beam, and then the bending operation can be performed.

[0004] However, the laser beam has a certain width, and when the sheet metal is slightly tilted, it is difficult for the operator to accurately judge the bending position of the steel plate, which may lead to positioning errors. Therefore, this utility model proposes a positioning machine for a steel plate bending machine with laser calibration to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a positioning machine for a steel plate bending machine with laser calibration, so as to solve the problems mentioned in the background art.

The telescopic rod in the limiting post is sleeved with the through hole opened at the other end of the fixed strip.

[0008] Preferably, a controller is fixedly connected to one side of the bottom of the bending machine body, the controller is electrically connected to the hydraulic cylinder, and the controller is electrically connected to the laser calibrator.

[0009] Compared with the prior art, the beneficial effects of this utility model are: the slider can quickly adapt to the length of the steel plate by sliding along the slide rail, and then the slider can be unlocked and locked by the fixing bar to achieve stable positioning of the steel plate. With the bending line projected by the laser calibrator, the operator can accurately judge the bending position of the steel plate and effectively prevent angle deviation.

[0015] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Example 1: Please refer to Figures 1-4This utility model provides a technical solution: a positioning machine for a steel plate bending machine with laser calibration, comprising: a bending machine body 1, a hydraulic cylinder 2 mounted on the top of the bending machine body 1, an upper die 3 mounted on the piston rod of the hydraulic cylinder 2, the hydraulic cylinder 2 being fixed to the top of the bending machine body 1 to utilize the linear drive trajectory of the hydraulic cylinder 2 to drive the upper die 3 to achieve precise vertical lifting and lowering, ensuring the stability of the upper die 3's movement trajectory, the piston rod being directly connected to the upper die 3 to efficiently transmit the hydraulic power of the hydraulic cylinder 2 to the upper die 3, and controlling the downward pressing depth of the upper die 3 through the extension and retraction of the piston rod to adapt to the bending angle of steel plates of different thicknesses, a steel plate worktable 4 mounted on the base of the bending machine body 1, the steel plate worktable 4 serving as a bearing platform for the steel plate, fixed to the base of the bending machine body 1, and required to maintain a vertical correspondence with the upper die 3 to ensure that the bending position of the steel plate after placement is aligned with the action point of the upper die 3, limit plates 5 being fixedly connected to both sides of the steel plate worktable 4. Fixed on both sides of the steel plate worktable 4, it is to limit the lateral displacement of the steel plate and prevent the steel plate from sliding to the sides during bending. The upper surface of the limiting plate 5 is provided with a slide rail 6, and a slider 7 is adapted to be installed in the slide rail 6. A clamping block 8 is fixedly connected to the top side of the slider 7. The slide rail 6 is opened on the upper surface of the limiting plate 5 and is adapted to the slider 7. It is to adjust the position of the clamping block 8 by sliding the slider 7, so that steel plates of different lengths can be fixed. The rigid connection between the clamping block 8 and the slider 7 can ensure the stable transmission of clamping force and prevent the steel plate from shifting due to force during bending. A laser calibrator 14 is fixedly connected to the top side of the bending machine body 1. The laser emission direction of the laser calibrator 14 is aligned with the bending center line of the upper die 3. The laser calibrator 14 is fixed to the top side of the bending machine body 1, and the laser emission direction is aligned with the bending center line of the upper die 3. Its core function is to mark the precise bending position on the surface of the steel plate by projecting a visible laser line.

[0017] Place the steel plate to be bent flat on the steel plate worktable 4, ensuring the steel plate is level and not warped or tilted. According to the bending requirements of the steel plate, activate the laser calibration function. The laser calibrator 14 emits a laser line. Observe whether the laser line is clearly projected onto the surface of the steel plate worktable 4. If the laser line deviates from the bending center line of the upper die 3, the operator fine-tunes the angle of the laser calibrator 14 until the laser line completely coincides with the center line of the cutting edge of the upper die 3. Push the slider 7 to slide along the slide rail 6 on the limit plate 5, moving the clamping block 8 to the other edge of the steel plate, making the clamping block 8 in close contact with the edge of the steel plate, initially clamping the steel plate. After positioning, fix the position of the slider 7 through the cooperation of the slider 7 and the slide rail 6 to prevent it from sliding during bending. Confirm that the clamping block 8 is in close contact with the edge of the steel plate, activate the hydraulic cylinder 2, causing the piston rod to drive the upper die 3 vertically downward, slowly contacting the steel plate and applying pressure. Observe the upper die 3. During the downward pressing process, it is ensured that it moves along a vertical trajectory and that the contact position with the steel plate accurately corresponds to the bending line marked by the laser until the preset bending angle is reached.

[0018] Example 2: Based on Example 1, a limiting strip 9 is fixedly connected to one side of the slide rail 6, and a limiting post 10 is fixedly connected to the upper surface of the limiting strip 9. A slot 16 is formed at the top of the limiting post 10, and one end of a spring 17 is fixedly connected to the bottom of the slot 16. A telescopic rod 18 is fixedly connected to the other end of the spring 17. A connecting rod 11 is fixedly connected to one side of the slider 7 near the limiting strip 9. The top of the connecting rod 11 is rotatably connected to one end of the fixing strip 12, and a through hole 13 is formed at the other end of the fixing strip 12. The telescopic rod 18 inside the limiting post 10 is sleeved with the through hole 13 at the other end of the fixing strip 12. The slot 16 at the top of the limiting post 10 houses the spring 17 and the telescopic rod 18, forming a retractable limiting assembly. The slider 7 is connected to the fixing strip 12 via the connecting rod 11. When the slider 7 slides along the slide rail 6 to a specific position, the through hole 13 of the fixing strip 12 will engage with the telescopic rod 18 of the limiting post 10 to limit its movement. This socketing method can directly limit the excessive sliding of slider 7, prevent it from detaching from slide rail 6 or colliding with other parts, and achieve precise control over the movement stroke of slider 7.

[0019] Confirm that there are no foreign objects obstructing the slide rail 6, slider 7, and limiting components. Check whether the telescopic rod 18 inside the limiting post 10 can freely extend and retract under the action of the spring 17. According to the required length of the steel plate, push the slider 7 to slide along the slide rail 6 towards the edge of the steel plate. At this time, the slider 7 drives the fixing strip 12 to move synchronously through the connecting rod 11. When the through hole 13 at the other end of the fixing strip 12 gradually approaches the telescopic rod 18 of the limiting post 10, the through hole 13 will first contact the top of the telescopic rod 18 and push it to compress the spring 17 until the through hole 13 is completely fitted into the outside of the telescopic rod 18. At this time, the sleeve structure forms a mechanical lock, restricting the slider 7 from continuing to slide, and achieving precise limiting of the slider 7.

[0020] Example 3: Based on Example 2, a controller 15 is fixedly connected to one side of the bottom of the bending machine body 1. The controller 15 is electrically connected to the hydraulic cylinder 2 and to the laser calibrator 14.

[0021] During use: First, the operator checks whether the bending machine body 1 is fixed and stable, and whether the surface of the steel plate worktable 4 is free of protrusions, welding slag, or other debris to avoid scratching the steel plate or affecting the positioning accuracy. Then, the operator turns on the power of the controller 15 and operates the laser calibrator 14 through the controller 15. The operator observes whether the laser line is continuous and clear. The laser line projected on the steel plate worktable 4 should be completely aligned with the center line of the cutting edge of the upper die 3. Next, the operator places the steel plate flat on the steel plate worktable 4, adjusts the position of the steel plate in the length direction, and aligns the edge to be bent with the laser line. The operator pushes the slider 7 to slide along the slide rail 6 on the limit plate 5 to the other edge of the steel plate. The slider 7 drives the fixing strip 12 to move synchronously through the connecting rod 11. When the through hole 13 of the fixing strip 12 approaches the telescopic rod 18 of the limit post 10, the through hole 13 will first contact the top of the telescopic rod 18 and push its compression spring 17. The telescopic rod 18 retracts into the slot 16 until the through hole 13... The slide block 7 is fully inserted into the telescopic rod 18. At this time, the slide block 7 is precisely limited, and the clamping block 8 is tightly fitted and fixed to the edge of the steel plate. Click the bend button on the controller 15. At this time, the upper die 3 automatically descends through the piston rod of the hydraulic cylinder 2 to bend the steel plate and complete the steel plate bending work.
