DETAILED DESCRIPTION

[0017] The technical solution of the present utility model is further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present utility model is not limited to the following.

[0018] like Figure 1 and Figure 2 As shown, a roll-forming machine with adjustable plate width comprises a base 1, two side plates 2 are arranged on the top of the base 1 opposite to each other, the side plates 2 have the freedom to move along the width direction of the base 1, and are used to adjust the width between the two side plates 2, an upper roll-forming assembly and a lower roll-forming assembly are arranged between the two side plates 2, the upper roll-forming assembly comprises a plurality of upper spindles 3, and the plurality of upper spindles 3 are arranged at equal intervals along the length direction of the base 1, one end of the upper spindle 3 is rotatably connected to one of the side plates 2, and the other end is slidably connected to the other side plate 2, an upper pressing roller 4 is sleeved on the upper spindle 3, and the lower rolling assembly comprises a plurality of rotatably arranged lower spindles 5, a lower spindle 5 is arranged directly below each upper spindle 3, a lower pressing roller 6 is sleeved on the lower spindle 5, the profile is shaped between the upper pressing roller 4 and the lower pressing roller 5, and the space between the two side plates 2 is shaped between the upper spindles 4 and the lower spindle 5. They can move relative to each other and adjust the spacing between the two side plates 2. The upper spindle 3 and the lower spindle 5 are connected to the side plates 2 by a rotating connection at one end and a sliding connection at the other end, which does not affect the rotation of the upper spindle 3 and the lower spindle 5. At the same time, they can adapt to the movement between the two side plates 2 without interference, so that the plate width of the roll-forming machine can be adjusted, thereby adapting to the processing of profiles of different widths, and has high versatility. It should be noted that each rotating connection end of the upper spindle 3 and the lower spindle 5 is connected with a sprocket, and all the sprockets of the upper spindles 3 are connected by a chain transmission, and all the sprockets of the lower spindles 5 are connected by a chain transmission. The upper spindle 3 and the lower spindle 5 are synchronously driven to rotate through the chain transmission method to complete the roll-forming operation. This belongs to the prior art and will not be repeated again.

[0019] In some embodiments, Figure 1As shown, the upper pressing roller 4 includes a fixed upper pressing roller 15 and a detachable upper pressing roller 16, the fixed upper pressing roller 15 is fixedly sleeved on the upper main shaft 3, and the two ends of the fixed upper pressing roller 15 are connected with the detachable upper pressing roller 16 by bolts, and the detachable upper pressing roller 16 is composed of two separate semicircular parts, and the lower pressing roller 6 includes a fixed lower pressing roller 17 and a detachable lower pressing roller 18, the fixed lower pressing roller 17 is fixedly sleeved on the lower main shaft 5, and the two ends of the fixed lower pressing roller 17 are connected with the detachable lower pressing roller 18 by bolts, and the detachable pressing roller 18 is composed of two separate semicircular parts. After the plate width adjustment between the two side plates 2 is completed, it is necessary to adjust the working width between the upper pressing roller 4 and the lower pressing roller 6 accordingly, so that the working width of the upper pressing roller 4 and the working width of the lower pressing roller 6 are both greater than or equal to the width of the processed profile, and the upper pressing roller 4 is adjusted. 4 and the lower pressing roller 6 are designed to be detachable structures. The detachable upper pressing roller 16 and the detachable lower pressing roller 18 of corresponding thickness can be replaced to complete the width adjustment of the upper pressing roller 4 and the lower pressing roller 6. In order to facilitate the detachable upper pressing roller 16 to be mounted on the upper main shaft 3 and the detachable lower pressing roller 18 to be mounted on the lower main shaft 5, the detachable upper pressing roller 16 and the detachable lower pressing roller 18 both adopt a semi-detachable structure. Taking the detachable upper pressing roller 16 as an example, the detachable upper pressing roller 16 includes two semi-annular pressing roller members, and the two semi-annular pressing roller members are connected to the fixed upper pressing roller 15 by bolts arranged at the ends, that is, the installation of the detachable upper pressing roller 16 can be completed without disassembling the upper main shaft 3. The detachable pressing roller 18 is installed in the same way, so that the upper pressing roller 4 and the lower pressing roller 6 can adapt to the working width and adjust the working width according to the plate width.

[0020] In some embodiments, Figure 2 As shown, two screw grooves 7 are spaced apart on the top of the base 1 along its length direction, and the screw groove 7 extends in the width direction of the base 1. A bidirectional threaded screw 8 is arranged in the screw groove 7, and the bidirectional threaded screw 8 is rotatably connected to the base 1. The bidirectional threaded screw 8 has two thread segments with opposite thread rotation directions. The two thread segments of the bidirectional threaded screw 8 are respectively threadedly sleeved with a first slider 9 and a second slider 10. The first slider 9 and the second slider 10 are both slidably adapted to the screw groove 7. The two side plates 2 are respectively fixedly connected to the first slider 9 and the second slider 10. The bidirectional threaded screw A screw motor 11 is provided at one end of the rod 8, and the output shaft of the screw motor 11 is connected to the bidirectional threaded screw 8. The screw motor 11 drives the bidirectional threaded screw 8 to rotate. Since the first slider 9 and the second slider 10 are respectively connected to two opposite thread segments of the bidirectional threaded screw 8, the moving direction of the first slider 9 is opposite to the moving direction of the second slider 10, and then the moving direction between the two side plates 2 is opposite. The spacing between the two side plates 2 is adjusted by the forward and reverse rotation of the screw motor 11 to achieve the purpose of adjusting the plate width to adapt to the processing of profiles of different widths.

[0021] In some embodiments, Figure 1 and Figure 2As shown, an opening is provided at the bottom of the side plate 2, and a lifting plate 12 is provided in the opening. The lifting plate 12 has the freedom to move along the height direction of the side plate 2. One end of the lower spindle 5 is rotatably connected to one of the lifting plates 12, and the other end is slidably connected to the other lifting plate 12. By moving the lifting plate 12 up and down, the spacing between the lower rolling assembly and the upper rolling assembly is adjusted, and profiles of different thicknesses can be roll-formed. The specific structure is that a lead screw 13 is vertically provided in the opening of the side plate 2, the lead screw 13 is rotatably connected to the side plate 2, and the lifting plate 12 is threadedly sleeved on the lead screw 13. A motor 14 is provided on the top of the side plate 2, and the output shaft of the motor 14 is connected to the screw 13. A vertical slide groove is provided on the inner wall of the side plate 2 at the opening. Vertical sliders are fixed on both sides of the lifting plate 12. The vertical sliders are slidably fitted in the vertical slide grooves. The motor 14 drives the screw 13 to rotate. Since the vertical sliders are slidably fitted in the vertical slide grooves, the rotational freedom of the vertical sliders is limited, so that the vertical sliders move linearly along the axial direction of the screw 13, thereby driving the lifting plate 12 to move up and down, and completing the spacing adjustment between the upper roller pressing assembly and the lower roller pressing assembly.
