[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] like Figures 1-4 As shown, a bending machine positioning device includes a movable seat 11 with a limit frame 12, a lower mold 1 with creases, and a side frame 2 that slides on the lower mold 1 and is symmetrically arranged. A limit member 3 that extends into a triangular shape in the default state is rotatably provided on the side frame 2, and a platform-shaped area for accommodating the plate is formed between the two limit members 3.

[0028] The side frame 2 is equipped with a height-adjustable ray assembly 4 that matches the creases on the surface of the lower mold 1.

[0029] Specifically, the movable seat 11 can move horizontally toward the lower mold 1, while the limiting frame 12 slides horizontally within the groove section opened on the upper surface of the movable seat 11. Both are existing technologies and will not be described in detail here.

[0030] Furthermore, the platform-shaped area between the two limiting members 3 allows the plate to be squeezed before placement and increases the area of ​​the platform-shaped area, so that the limiting members 3 can be used to adapt to the clamping of plates of different specifications, so that the plates are clamped under pressure.

[0031] By adjusting the positions of the two side frames 2 on the left and right sides of the lower mold 1, the two side frames 2 limit the two ends of the plate (one end is not manually supported and the other end is fixed by the limiting frame 12), and the two limiting parts 3 clamp the two ends of the plate, so that the plate is restricted and fixed in front, back, left and right to wait for the tool to move down. The limiting parts 3 have the ability to store force and rotate. The purpose is to use the variable clamping range to adapt to plates with different shaped sides, so that the plate is kept in a stable clamped state, thereby reducing the problem of left and right deviation of the plate during placement. At the same time, the ray assembly 4 emits a line bundle parallel to the crease position, and after the plate is placed stably, it is aligned with the marking line and the ray, so that the two lines match, thereby improving the ability to judge the accuracy of the plate placement and reducing the interference caused by the plate deviation to the bending position offset.

[0032] As a further embodiment of this utility model, the lower end of the side frame 2 is fixedly equipped with symmetrically arranged connecting blocks 21 that are snapped onto the side of the lower mold 1.

[0033] Specifically, the connecting block 21 has threaded holes for installing bolts.

[0034] During the sliding process of the side frame 2, the connecting block 21 slides against the front and rear sides of the lower mold 1. Then, the bolt passes through the connecting block 21 to abut against the side of the lower mold 1, thereby fixing the connecting block 21 to the side of the lower mold 1. This completes the position fixation of the side frame 2, making it convenient for the side frame 2 to limit the plate at any position on the lower mold 1.

[0035] As another embodiment provided by this utility model, a rotating shaft 31 located on the end face of the side frame 2 is fixedly installed on the limiting member 3.

[0036] Specifically, a recess is provided on the end face of the side frame 2 for the rotating shaft 31 to rotate, and a torsion spring is provided at the rotating position of the rotating shaft 31 and the recess. The torsion spring and its installation method are existing technologies and will not be described in detail here.

[0037] The torsion spring on the rotating shaft 31 provides elastic storage for the limiting member 3, so that the limiting member 3 can maintain elastic clamping on both ends of the plate during the release of the torsion spring force.

[0038] As another embodiment further provided in this utility model, a clamping plate 32 is fixedly mounted on the rotating shaft 31.

[0039] Specifically, the torsion spring maintains a predetermined angle between the end face of the clamping plate 32 and the side frame 2 in the default state, and a rubber pad is fixedly installed at the end of the rotating shaft 31. The purpose is to provide damping during rotation to reduce the shaking caused by left and right offset.

[0040] By contacting the left and right ends of the plate with the end face of the clamping plate 32, it can provide clamping ability for the ends of the plate. On the other hand, the plate will tilt upward during the bending process, so the clamping plate 32 can still provide clamping and limiting for the plate during the process. That is, the tilted end of the plate slides on the end face of the clamping plate 32, thereby reducing the slight positional displacement of the plate due to the force during the bending process.

[0041] As another embodiment provided in this utility model, the X-ray assembly 4 is provided with a connecting strip 41, and the side frame 2 is provided with a plurality of screw holes 23 that cooperate with the connecting strip 41.

[0042] The horizontal installation position of the connecting strip 41 is adjusted by the equally spaced screw holes 23, which causes the ray assembly 4 to adjust to a specified height to fit the plate of the corresponding thickness, thereby ensuring the alignment accuracy of the marking line and the ray and reducing the occurrence of light shading.

[0043] As another embodiment of this utility model, a spotlight 42 is fixedly installed on the connecting strip 41, and a notch 22 is provided on the side frame 2 for the spotlight 42 to emit light.

[0044] Specifically, spotlight 42 uses a common ray laser (such as the JBP6520Z-004 model lamp from Lanji Optoelectronics, which is existing technology and will not be described in detail here), and notch 22 is opened upward to the upper end of side frame 2.

[0045] The notch 22 allows the spotlight 42 to continue to emit light normally when the height is adjusted, making the assembly of the panels more versatile during placement.

[0046] As another embodiment of this utility model, the clamping plate 32 is provided with a window 33 that communicates and cooperates with the notch 22.

[0047] The window 33 allows light to pass through even after the clamp 32 is rotated, thus ensuring the high efficiency of the light source for calibration when it is located on the plate.

[0048] As another embodiment of this utility model, an arc plate 34 is fixedly installed at the end of the clamping plate 32, and a protrusion that slides with the inner side wall of the arc plate 34 is provided on the side frame 2.

[0049] Specifically, the protrusion is an extension plate integrally formed on the two sides of the side frame.

[0050] The protrusions provide resistance to the arc plate 34, preventing excessive deformation and severe shaking of the outer surface of the arc plate 34 when subjected to force. At the same time, the outer surface of the arc plate 34 also has a good anti-collision effect, preventing impact damage during manual docking.

[0051] As another embodiment further provided in this utility model, the clamping plate 32 is specifically an alloy metal plate.

[0052] The use of alloy metal material makes the overall hardness of the clamping plate 32 higher, making its clamping effect more stable. It also has good wear resistance. The pointed tip formed at the intersection of the end of the clamping plate 32 and the arc plate 34 can be used to clamp plates whose front and rear lengths exceed those of the side frame 2, thereby improving the ability to fix different components.

[0053] As another embodiment further provided in this utility model, the arc plate 34 is specifically an elastic metal plate.

[0054] The elastic metal plate allows the arc plate 34 to maintain its sliding position and protrusion during rotation, thus making the movement of the clamping plate 32 more stable.

[0055] Working principle: By adjusting the positions of the two side frames 2 on the left and right sides of the lower mold 1, the two side frames 2 limit the two ends of the plate, and the two limiting parts 3 clamp the two ends of the plate, so that the plate is restricted and fixed in front, back and left and right to wait for the tool to move down. The limiting parts 3 have the torsion spring storage rotation capability of the upper rotating shaft 31, so that the clamping plate 32 can adapt to the plate with different shaped sides by using the variable clamping range, so that the plate is kept in a stable clamping state, thereby reducing the problem of left and right deviation of the plate during placement. At the same time, the spotlight 42 shines a line bundle parallel to the crease position, and after the plate is placed stably, it is aligned with the marking line and the line, so that the two lines match, thereby improving the ability to judge the accuracy of the plate placement.

[0056] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
