[0002] In the field of sheet metal processing, the side bending or flanging of the sheet metal is often achieved through die stamping. Due to the inherent rebound characteristics of the sheet metal material, the accuracy of the bending part is often difficult to ensure, which in turn affects the overall assembly quality of the product. The traditional calibration wheel has a fixed structure and cannot calibrate and shape sheets with different side inclination angles, which greatly limits the adaptability and efficiency of the production line. For this reason, we propose a forming calibration mechanism for sheet metal processing. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Refer to the attached Figure 1-5 A forming calibration mechanism for plate processing comprises an archway 1, on which a first calibration wheel 2, a second calibration wheel 3 and a third calibration wheel 4 are arranged, and a calibration channel for calibrating the bottom and side connection part of the plate is formed between the first calibration wheel 2, the second calibration wheel 3 and the third calibration wheel 4, and the calibration channel calibrates the bending part where the bottom and side of the plate are connected, so that the bending degree of the connection part can be more accurate;

[0025] The third calibration wheel 4 includes a circumferentially arranged calibration unit that can rotate along its axis. When the plate moves along the calibration channel, its side will fit against the calibration unit. The inclination angle of the calibration unit is adjustable and abuts against the side of the plate, so it can adapt to the calibration of plates with different bending angles. There is no need to prepare special calibration wheels for plates with each bending angle, which reduces the cost of equipment procurement and storage. By accurately adjusting the inclination angle of the calibration unit, it can ensure that the contact between the calibration wheel and the side of the plate is closer and more accurate, thereby improving the accuracy and consistency of the calibration, ensuring product quality and reducing the scrap rate.

[0026] In this embodiment, the third calibration wheel 4 also includes a center positioning unit, and the third calibration wheel 4 is installed on the arch 1 through the center positioning unit. The calibration unit is circumferentially arranged on the outside of the center positioning unit, and the axial center lines of the two are the same, so that the circumferentially arranged calibration unit can maintain consistency during rotation, and the top center positioning unit of the calibration unit is rotatably connected, and the top of the calibration unit rotates with the top position of the center positioning unit as the center of the circle, which is used to adjust the inclination angle of the calibration unit. The bottom of the calibration unit is subjected to force and rotates along the top, so that the inclination angle of the calibration unit changes, which is convenient for adapting to the calibration of plates with different bending angles.

[0027] In this embodiment, the center positioning unit includes a positioning cylinder 411, and a ring 413 is connected to the top of the positioning cylinder 411 through multiple connecting arms 412 to improve the stability of the connection between the ring 413 and the positioning cylinder 411. The ring 413 passes through the top of the circumferentially arranged calibration unit to realize the rotation of the calibration unit along the axis of the ring 413, so that the overall inclination angle of the circumferentially arranged calibration unit can remain consistent when it changes.

[0028] In this embodiment, the calibration unit includes a calibration roller 421, and the side wall of the calibration roller 421 abuts against the side edge of the plate to form a support for the side edge of the plate. Both ends of the calibration roller 421 are rotatably connected to a connecting head 422. The diameter of the calibration roller 421 is larger than the diameter of the connecting head 422, so that the connecting head 422 does not contact the plate, thereby preventing the connecting head 422 from being deflected by force and affecting the calibration of the plate. A connecting plate 423 is provided on one side of the connecting head 422, and the upper connecting plate 423 is sleeved on the outer wall of the ring 413 to realize the rotation of the calibration roller 421 along the axis of the ring 413, so that the inclination angle of the calibration roller 421 changes, which is convenient for coordinating the calibration of plates with different side inclination angles.

[0029] The adjusting unit is provided at the lower side of the calibration unit, and the adjusting unit comprises a driving cylinder 431 which is sleeved on the outer wall of the positioning cylinder 411 and threadedly connected thereto, and an annular groove 432 is provided on the outer wall of the driving cylinder 431, and a slider 433 is slidably connected in the annular groove 432, and a connecting rod 434 is hinged on the outer side of the slider 433, and the connecting rod 434 is hinged to the connecting plate 423 on the lower side on the side away from the slider 433, and is used to push or pull the bottom of the calibration roller 421, and rotate the driving cylinder 431. With the cooperation of the thread on the outer wall of the positioning cylinder 411, the driving cylinder 431 can move up and down on the outer wall of the positioning cylinder 411, and further make the slider 433 in the annular groove 432 move up and down. At this time, the inclination angle of the calibration roller 421 changes under the drive of the connecting rod 434, so that the angle of the calibration roller 421 can be quickly adjusted as needed to adapt to the calibration of plates with different side inclination angles. The adjustment method is simple and efficient.

[0030] In this embodiment, a forward protrusion is circumferentially provided on the outer wall of the top of the driving cylinder 431 , and the protrusion is close to the positioning cylinder 411 , so that the driving cylinder 431 can be rotated by the protrusion.

[0031] In this embodiment, the first calibration wheel 2 is located above the second calibration wheel 3 and the third calibration wheel 4 for abutting against the top of the plate, and the second calibration wheel 3 is located below the plate for abutting against the bottom of the plate.

[0032] In this embodiment, an adjusting shaft 5 is provided on the archway 1, and a sliding block 6 which can move along its axial direction is provided on the adjusting shaft 5. A positioning rod 7 inserted into the positioning cylinder 411 is provided on the top of the sliding block 6. The second calibration wheel 3 is arranged on the outer wall of the adjusting shaft 5, and its top is lower than the bottom of the third calibration wheel 4. By adjusting the position of the sliding block 6 on the adjusting shaft 5, the position of the third calibration wheel 4 relative to the first calibration wheel 2 and the second calibration wheel 3 can be adjusted, and then the position of the first calibration wheel 2 on the archway 1 is adjusted, so that the vertical cross-sectional shape of the calibration channel is changed, so that it is convenient to calibrate plates of different thicknesses.
