[0036] The reference numerals in the accompanying drawings include: roll forming device M, frame 1, support assembly 2, first drive shaft 201, second drive shaft 202, flat roller 301, vertical roller 302, inclined roller 303, forming channel 304, eccentric sleeve 305, moving device 4, drive mechanism 401, conversion mechanism 402, inner bushing 403, outer bushing 404, lifting mechanism 5, heating and heat replenishment device 6, first processing subsystem K1, and second processing subsystem K2.

[0037] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0038] Figure 1 This is a schematic diagram of the structure of the molding equipment distributed on the operating side, as shown in an embodiment of this application.

[0039] Figure 2 This is a schematic diagram of the structure of the molding equipment distributed on the transmission side, as shown in an embodiment of this application.

[0040] See appendix Figure 1 and Figure 2 As shown, the roll forming device M includes:

[0041] Rack 1,

[0042] Support component 2 includes at least two parallel drive shafts, which are mounted on frame 1;

[0043] At least one molding device is provided, which includes a first molding group and a second molding group. The first molding group and the second molding group are arranged side by side on a drive shaft. Both the first molding group and the second molding group include molding rollers. The molding rollers in the first molding group and the molding rollers in the second molding group cooperate to form a molding channel 304. At least one molding device is the first molding device. At least one molding roller in the first molding device is an inclined roller 303. An eccentric sleeve 305 for mounting the inclined roller 303 is installed on the drive shaft. The inclined roller 303 is sleeved outside the eccentric sleeve 305 and can rotate radially on the eccentric sleeve.

[0044] The mobile device 4 is configured to correspond to the first molding group and the second molding group respectively, and is used to drive the first molding group and the second molding group to move along the drive shaft respectively.

[0045] In this embodiment, the molding equipment is supported by a drive shaft, and the position of the molding equipment on the drive shaft is adjusted by a moving device 4. When installing the inclined roller 303, an eccentric sleeve 305 is used to achieve an inclined installation of the roller 303. Rotating the eccentric sleeve 305 adjusts the position of the inclined roller 303, thereby adjusting the inclination angle α. Compared with the prior art, this solution eliminates the need for a drive mechanism 401 to drive the inclined roller 303 to rise and fall; the same purpose can be achieved by rotating the eccentric sleeve 305, resulting in lower costs and effective space saving.

[0046] For example, to meet different needs, the tilt angle a is 0 to 30°, and the eccentricity e of the eccentric sleeve 305 is 0 to 10 mm.

[0047] For example, the tilt angle 'a' is 0°, 25°, or 30°; the eccentricity 'e' is 0 mm, 4 mm, 5 mm, or 10 mm.

[0048] It should also be noted that if only one set of molding equipment is set up, it is single-flow; if two sets are set up, it is dual-flow. Figure 1 and Figure 2 Only the single-stream case is shown in the image.

[0049] Figure 3 This is a schematic diagram of a single inclined roller 303 mounted on a first drive shaft 201, as shown in an embodiment of this application.

[0050] Figure 4 This is a schematic diagram of a single inclined roller 303 mounted on a second drive shaft 202, as shown in an embodiment of this application.

[0051] like Figure 3 and Figure 4 As shown, in an exemplary embodiment of this application, the drive shafts are a first drive shaft 201 and a second drive shaft 202 arranged in parallel, and the inclined roller 303 is mounted on the first drive shaft 201 or the second drive shaft 202.

[0052] It is worth noting that the number and installation position of the slanted rollers 303 can be set according to the shape to be formed from the molding material. In this embodiment, only one slanted roller 303 is provided, which can be installed on the first drive shaft 201 or on the second drive shaft 202.

[0053] Figure 5 This is a schematic diagram showing the structure of two inclined rollers 303 mounted on different drive shafts in an embodiment of this application.

[0054] Figure 6 This is a schematic diagram of the structure in an embodiment of this application, showing two slanted rollers 303 respectively mounted on different drive shafts.

[0055] like Figure 5 and Figure 6 As shown, in an exemplary embodiment, the drive shafts are a first drive shaft 201 and a second drive shaft 202 arranged in parallel. The first forming device has two inclined rollers 303, one inclined roller 303 is arranged on the first drive shaft 201 and the other inclined roller 303 is arranged on the second drive shaft 202.

[0056] In this embodiment, two inclined rollers 303 are provided, and the two inclined rollers 303 are respectively installed on different drive shafts to meet the required molding shape of the molding material.

[0057] Figure 7 This is a schematic diagram of the structure of two inclined rollers 303 mounted on the first drive shaft 201, as shown in the embodiment of this application.

[0058] Figure 8 This is a schematic diagram of the structure of two inclined rollers 303 mounted on the second drive shaft 202, as shown in the embodiment of this application.

[0059] like Figure 7 and Figure 8 As shown, in an exemplary embodiment, the drive shafts are a first drive shaft 201 and a second drive shaft 202 that are parallel to each other. The first forming device has two inclined rollers 303, and both inclined rollers 303 are mounted on the first drive shaft 201 or the second drive shaft 202.

[0060] In this embodiment, there are two inclined rollers 303 in the same molding equipment, and both inclined rollers 303 are mounted on the same drive shaft to meet the molding shape of the molding material.

[0061] In one exemplary embodiment, the first molding device has two inclined rollers 303, which are symmetrically arranged along the vertical line of the drive shaft; or the two inclined rollers 303 are symmetrically arranged along the center of the molding channel 304.

[0062] like Figure 7 and Figure 8 As shown, the two inclined rollers 303 are symmetrically arranged along the vertical line of the drive shaft. Figure 4 and Figure 5 As shown, the two inclined rollers 303 are centrally symmetrical about a central point.

[0063] Figure 9 This is a schematic diagram of the structure of the roll forming device M when two sets are provided for the molding equipment shown in the embodiments of this application.

[0064] Figure 10 This is a schematic diagram of the structure of the roll forming device M when two sets are set up for another forming equipment shown in the embodiments of this application.

[0065] like Figure 9 and Figure 10 As shown, in an exemplary embodiment, at least one molding device in the molding equipment is a second molding device, the first molding device and the second molding device are arranged side by side on the drive shaft, and the second molding group of the first molding device and the first molding group of the second molding device are arranged adjacent to each other.

[0066] In this embodiment, a dual-flow molding process is achieved by setting up a first molding device and a second molding device.

[0067] In an exemplary embodiment, the mobile device 4 includes a bushing assembly, which includes an inner bushing 403 and an outer bushing 404. The inner bushing 403 is respectively disposed corresponding to the second molding group of the first molding device and the first molding group of the second molding device. The outer bushing 404 is respectively disposed corresponding to the first molding group of the first molding device and the second molding group of the second molding device. The inner bushing 403 is slidably mounted on the drive shaft along the drive shaft, and the outer bushing 404 is slidably mounted outside the inner bushing 403 along the axis of the inner bushing 403.

[0068] It is worth noting that if it is a single-flow molding process, only the inner bushing 403 needs to be set, and the outer bushing 404 is not required.

[0069] In this embodiment, the inner bushing 403 is used to control the molding groups on adjacent sides of the molding equipment. The inner bushing 403 is used to drive the second molding group of the first molding equipment and the first molding group of the second molding equipment. The outer bushing 404 is used to drive the first molding group of the first molding equipment and the second molding group of the second molding equipment.

[0070] In one exemplary embodiment, the mobile device 4 further includes:

[0071] The drive mechanism 401 is mounted on the frame 1 and is respectively set for each inner bushing 403 and each outer bushing 404, and is used for rotational output;

[0072] The conversion mechanism 402 is installed inside the frame 1 and cooperates with the output of the drive mechanism 401 to convert the rotational output of the drive mechanism 401 into linear motion. The output end of the conversion mechanism 402 is connected to the corresponding inner bushing 403 or outer bushing 404.

[0073] For example, drive mechanism 401 includes a motor.

[0074] For example, the conversion mechanism 402 can be a lead screw structure, or it can be a gear, rack, turbine, worm, or other structure that can convert rotary motion into linear motion.

[0075] In one exemplary embodiment, the first molding device is disposed on the operating side, and the second molding device is disposed on the transmission side;

[0076] or

[0077] The first forming device is located on the transmission side, and the second forming device is located on the operation side.

[0078] In this embodiment, in order to meet different needs, the first molding device can be set on the transmission side or the operation side.

[0079] Figure 11 This is a schematic diagram of the roll forming system shown in the embodiments of this application.

[0080] like Figure 11 As shown, the roll forming system includes two processing subsystems arranged side by side. The processing subsystem includes a heating and heat replenishing device 6 and a roll forming device M. The heating and heat replenishing device 6 is located on the inlet side of the roll forming device M.

[0081] In this embodiment, the molding material is first heated, and then molded by the roll forming device M to increase the ease of molding.

[0082] For example, the heating and heat replenishment device 6 includes a high-frequency heating coil, etc.

[0083] In an exemplary embodiment, the roll forming system includes at least two first processing subsystems K1 and second processing subsystems K2 arranged side by side. Both the first processing subsystem K1 and the second processing subsystem K2 include a heating and heat replenishing device 6 and a roll forming device M. The heating and heat replenishing device 6 is located on the inlet side of the roll forming device M. The first forming device in the first processing subsystem K1 and the first forming device in the second processing subsystem K2 are staggered.

[0084] In this embodiment, the first molding device in the first processing subsystem K1 and the first molding device in the second processing subsystem K2 are staggered. That is, when the first molding device in the first processing subsystem K1 is set on the operating side, the first molding device in the second processing subsystem K2 is set on the transmission side; when the first molding device in the first processing subsystem K1 is set on the transmission side, the first molding device in the second processing subsystem K2 is set on the operating side.

[0085] It is worth noting that, due to space constraints, the distance A between the two forming devices (A ranges from ~400 to 2600 mm) is small. In order to avoid interference between the inclined rollers 303 in the two forming devices during the dual-flow roll forming process, only one first forming device with inclined rollers 303 is set up in each processing subsystem.

[0086] It should also be noted that the second forming equipment is a forming equipment without the inclined roller 303, which mainly plays the role of clamping the forming material.

[0087] For example, the second molding device includes four flat rollers 301 mounted on a drive shaft, with two flat rollers 301 disposed on the upper side of the molding channel 304 and two flat rollers 301 disposed on the lower side of the molding channel 304.

[0088] For example, in order to achieve synchronous action, the second forming device includes a column, which is rotatably connected to the corresponding inner bushing 403 through a bearing. The column is set perpendicularly to the drive shaft, and a vertical roller 302 is set on the column. The vertical roller 302 is set on the left and right sides of the forming channel 304. The vertical roller 302 and the flat roller 301 form the forming channel 304.

[0089] It should also be noted that the first forming equipment and the second forming equipment are identical in structure, except that the setting of the inclined roller 303 in the first forming equipment is different from that in the second forming equipment.

[0090] For example, in order to achieve the overall lifting of the roll forming device M, a lifting mechanism 5 can be set on the roll forming device M. The lifting mechanism 5 can be an existing jack, which can be driven by a screw, hydraulic cylinder, etc.

[0091] For example, depending on actual needs, if the flat roller 301 needs to move, the drive shaft can be rotatably mounted on the frame 1 along its own axis. A motor, reducer, coupling, etc., can be installed outside the frame 1 to enable the rotation of the drive shaft and meet the rotation requirements of the flat roller. Furthermore, the drive shaft can be quickly replaced on the operating side via a push-pull device.

[0092] It should also be noted that the inner bushing 403 and the drive shaft achieve a sliding fit through the protrusions and grooves provided along the axis of the drive shaft, and the inner bushing 403 and the outer bushing 404 achieve a sliding fit through the protrusions and grooves provided along the axis of the inner bushing 403.

[0093] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
