Description

Technical Field

[0001] This utility model belongs to the technical field of roller pressing equipment, and relates to a roller adjusting and positioning device. Background Technology

[0002] Roll forming devices are common equipment on sheet metal production lines, used in multiple processes such as sheet metal lamination and leveling. A typical roll forming device consists of an upper pressure roller assembly and a lower pressure roller assembly. The upper pressure roller assembly is a moving component, while the lower pressure roller assembly is a fixed component. The gap between the pressure rollers is adjusted by moving the upper pressure roller assembly to meet various process requirements. The upper pressure roller assembly is lifted and lowered by a cylinder; when not in use, it can also be moved upwards and hung up using the cylinder.

[0003] However, in actual production, it was found that the above-mentioned roller pressing device has a great safety hazard: the cylinder needs to maintain pressure to keep the upper pressing roller assembly in the hanging state. When the cylinder loses pressure due to malfunction or other reasons, the lower pressing roller assembly will fall freely under its own weight, causing a serious safety accident. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a pressure roller adjustment and positioning device, which improves system stability, safety, and cylinder life.

[0005] To solve the above-mentioned technical problems, the objective of this utility model is achieved through the following technical solution:

The upper pressure roller assembly includes an upper pressure roller and upper bearing seats at both ends. The lower pressure roller assembly includes a lower pressure roller and lower bearing seats at both ends. The upper bearing seats are slidably mounted on the frame and are driven by a cylinder to move between a hanging position and a roller pressing position. The lower bearing seats are fixedly connected to the frame. A support device is provided below the upper bearing seats. When the upper bearing seats are in the hanging position, the support device abuts against the bottom of the upper bearing seats to form its support structure.

[0007] In the aforementioned pressure roller adjustment and positioning device, the support device is fixed to the upper surface of the lower bearing seat by a base, and the top of the support device forms a support surface that contacts the bottom of the upper bearing seat; preferably, the base is fixed to the central area of ​​the upper surface of the lower bearing seat by a number of fasteners.

[0008] In the aforementioned pressure roller adjustment and positioning device, the support device includes a support sleeve disposed on the base and a support rod coaxially slidably disposed within the support sleeve, the top end of the support rod forming a support surface that contacts the bottom of the upper bearing seat; preferably, the support sleeve is integrally formed with the base or welded and fixed.

[0009] In the aforementioned pressure roller adjustment and positioning device, a through adjustment groove is provided on the side wall of the support sleeve. The adjustment groove includes a vertical height adjustment section and a locking section extending horizontally at the upper end. An adjustment rod is provided on the side of the support rod, extending radially and passing through the adjustment groove. The adjustment rod can slide along the adjustment groove to drive the support rod to rise and fall. Preferably, the outer end of the adjustment rod is provided with an adjustment handle for easy operation.

[0010] In the aforementioned pressure roller adjustment and positioning device, a support platform is provided at the top of the support rod, and the support platform is positioned directly opposite the center area of ​​the bottom of the bearing seat; preferably, the support platform is a circular plate or a square plate.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figures 1-4 :

[0022] A pressure roller adjustment and positioning device includes a frame 1, on which an upper pressure roller assembly and a lower pressure roller assembly are arranged vertically. The upper pressure roller assembly includes an upper pressure roller 2 and upper bearing seats 3 at both ends. The lower pressure roller assembly includes a lower pressure roller 4 and lower bearing seats 5 at both ends. The upper bearing seats 3 are slidably mounted on the frame 1 and are driven by a cylinder 6 to move between a hanging position and a roller pressing position. The lower bearing seats 5 are fixedly connected to the frame 1. A support device 7 is provided below the upper bearing seats 3. When the upper bearing seats 3 are in the hanging position, the support device 7 abuts against the bottom of the upper bearing seats 3 to form its support structure.

[0023] Comparison Appendix Figure 1 and attached Figure 3 In this embodiment, the adjustment method of the roller gap is the same as that in the prior art. The upper bearing seat 3 is driven to rise and fall by the cylinder 6, which in turn drives the upper pressure roller 2 to rise and fall (the cylinder 6 is fixed on the top of the frame 1, and its piston rod is set vertically downward and connected to the upper bearing seat 3. The upper bearing seat 3 is raised and lowered by the extension and retraction of the piston rod). When the upper bearing seat 3 is driven to rise to the hanging position by the cylinder 6, the support device 7 is adjusted to make it abut against the bottom of the upper bearing seat 3. At this time, the support device 7 provides support for the upper bearing seat 3, completely eliminating the risk of the upper pressure roller 2 falling accidentally. If necessary, the cylinder 6 can also be depressurized, and the support device 7 can provide support. When it is necessary to adjust the upper bearing seat 3 downward, the support device 7 is first adjusted to make it disengage from the upper bearing seat 3, while avoiding the downward stroke of the upper bearing seat 3. At this time, the upper bearing seat 3 can move downward normally under the drive of the cylinder 6.

[0024] Comparison Appendix Figure 2 and attached Figure 4 In this embodiment, the specific structure of the support device 7 is as follows:

[0025] The aforementioned support device 7 is fixed to the upper surface of the lower bearing seat 5 by the base 8, and the top of the support device 7 forms a support surface that contacts the bottom of the upper bearing seat 3; preferably, the base 8 is fixed to the central area of ​​the upper surface of the lower bearing seat 5 by a number of fasteners.

[0026] Furthermore, the support device 7 includes a support sleeve 9 disposed on the base 8, and a support rod 10 coaxially slidably disposed within the support sleeve 9. The top end of the support rod 10 forms a support surface that contacts the bottom of the upper bearing seat 3. Preferably, the support sleeve 9 is integrally formed with the base 8 or welded and fixed.

[0027] Furthermore, the side wall of the support sleeve 9 is provided with a through adjustment groove 11, the adjustment groove 11 includes a vertical height adjustment section 11a and a locking section 11b extending horizontally at the upper end, and the side of the support rod 10 is provided with an adjustment rod 12 extending radially and passing through the adjustment groove 11, the adjustment rod 12 can slide along the adjustment groove 11 to drive the support rod 10 to rise and fall; preferably, the outer end of the adjustment rod 12 is provided with an adjustment handle for easy operation.

[0028] By moving the adjusting rod 12, the state of the support rod 10 can be changed. When support is needed, the adjusting rod 12 is pulled to move upward along the axial height adjusting section 11a, and then moves circumferentially to the locking section 11b. The bottom of the adjusting rod 12 is limited by the bottom of the locking section 11b and cannot move downward, thus keeping the support rod 10 at a predetermined height. At this predetermined height, the support surface of the support rod 10 abuts against the bottom of the upper bearing seat 3 to form a support structure. When support needs to be withdrawn, the adjusting rod 12 is moved in the opposite way, causing the adjusting rod 12 to slide to the bottom of the height adjusting section 11a. When the cylinder 6 maintains pressure, the cylinder 6 can balance the gravitational load generated by the upper pressure roller 2 assembly. The support surface of the support rod 10 can rotate relative to the upper bearing seat 3 for easy adjustment.

[0029] To make the support structure more stable, a support platform 13 is provided on the top of the support rod 10, and the support platform 13 is positioned directly opposite the center area of ​​the bottom of the bearing seat 3; preferably, the support platform 13 is a circular plate or a square plate; the support rod 10 is fixedly connected to the support platform 13 by welding or other methods, and several reinforcing ribs can also be provided between the support rod 10 and the support platform 13 to increase the connection strength between the two.

[0030] To achieve a more balanced and stable lifting and lowering of the upper bearing seat 3, two cylinders 6 are used, each cylinder 6 independently driving one upper bearing seat 3; two support devices 7 are used, with each support device 7 positioned corresponding to the bottom of one upper bearing seat 3.

[0031] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
