DETAILED DESCRIPTION

[0034] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0035] Embodiment 1:

[0036] In view of the needs of small-batch, high-precision, and complex curvature metal sheet forming, this embodiment provides a steel plate 14 roll forming device, which is suitable for roll forming and bending steel plates 14 with a thickness between 0.5 mm and 3 mm. The formed steel plates 14 are used for new energy buses, such as Figure 1-Figure 5 As shown, the device includes a support base 01, a movable support base 05, a movable pressure block 06, an active roller 11, a driven roller 12, a screw assembly, a shaking handle 10, etc. The movable support base 05 is slidably connected to the support base 01, and a plurality of active rollers 11 and driven rollers 12 are installed between the two, and the active roller 11 is connected to the shaking handle 10; the steel plate 14 to be processed is arranged between the active roller 11 and the driven roller 12, and the steel plate 14 is roll-formed between the active roller 11 and the driven roller 12 by operating the shaking handle 10.

[0037] Specifically, Figure 1 and Figure 3 As shown, the support base 01 is a fixed base. In order to cooperate with the movement of the movable support base 05 and install the active roller 11 and the driven roller 12, the support base 01 has a horizontal plane and a vertical plane, that is, the cross-sectional shape of the support base 01 is L-shaped; a slide rail 02 is installed on the horizontal plane of the support base 01, and a slider 03 is installed on the bottom surface of the movable support base 05. The slider 03 is slidably connected to the slide rail 02, so that the movable support base 05 can move along the horizontal plane of the support base 01 to approach or move away from the vertical plane of the support base 01; when the movable support base 05 is away from the support base 01, it is convenient to take the roll-formed workpiece from the side, and can achieve the purpose of quickly switching the rollers due to changes in the workpiece size.

[0038] In order to ensure the stability of the movement of the movable support seat 05, the support base 01 is equipped with at least two slide rails 02, and each slide rail 02 corresponds to at least one slider 03. For example, the support base 01 is equipped with two slide rails 02, and the slide rails 02 are arranged near the ends of the support base 01, and the movable support seat 05 cooperates with the slide rails 02 through the sliders 03 near the two ends.

[0039] The shape support of the movable support seat 05 can be set arbitrarily, as long as the movable support seat 05 can install the driven roller 12 and realize the connection with the slide rail 02; in this embodiment, the movable support seat 05 includes a mounting plate and a mounting block fixed to the upper side of the mounting plate, a slider 03 is installed at the bottom of the mounting plate, and the mounting block is adapted to the vertical surface of the support base 01.

[0040] like Figure 1 and Figure 2 As shown, the driven rollers 12 are arranged in parallel between the movable support seat 05 and the support base 01 . In this embodiment, two driven rollers 12 are arranged, and the axial direction of the driven rollers 12 is parallel to the setting direction of the slide rail 02 .

[0041] In order to adapt to the rolling of steel plates 14 of different thicknesses, one of the driven rollers 12 is configured as a movable structure; Figure 1 and Figure 4 As shown, the mounting block of the movable support seat 05 and the vertical surface of the support base 01 are provided with adjustment holes 15 corresponding to each other. The adjustment holes 15 are strip holes. The driven roller 12 installed in the strip hole can change its distance relative to another driven roller 12 .

[0042] Bearings 13 are installed at both ends of the driven roller 12, and the bearings 13 are arranged in the adjustment holes 15; an adjustment rod 04 is arranged along a direction perpendicular to the setting direction of the slide rail 02 and parallel to the horizontal plane direction of the support base 01, and the mounting block of the movable support seat 05 and the vertical surface of the support base 01 are both installed with the adjustment rod 04, such as Figure 6 and Figure 7 As shown, the adjusting rod 04 passes through the mounting block and the vertical surface until it extends into the adjusting hole 15; the adjusting rod 04 and the fixed bearing of the driven roller 12 are connected by a pin hole, and two limit grooves are provided at the mating ends of the adjusting rod 04 and the above-mentioned bearing, and the two limit grooves are respectively arranged on both sides of the bearing. Elastic retaining rings 16 are stuck in the limit grooves, and rotating the adjusting rod 04 can realize that the elastic retaining ring 16 pushes the driven roller 12 to move.

[0043] Another driven roller 12 is connected to the mounting block of the movable support seat 05 and the vertical surface of the support base 01 through a bearing 13. The bearing 13 and the driven roller 12 are clearance-matched, which facilitates the replacement of the roller set. In this embodiment, the bearing 13 is bolted to the support base 01, the movable support seat 05 and the movable pressure block 06 respectively.

[0044] Movable pressure blocks 06 are installed on the upper side of the support base 01 and the movable support base 05, that is, two movable pressure blocks 06 are set, and the movable pressure blocks 06 are connected to the support base 01 and the movable support base 05 through a screw assembly. The active roller 11 is installed between the two movable pressure blocks 06. By adjusting the screw assembly, the distance between the movable pressure block 06 and the top surface of the support base 01 and the movable support base 05 can be changed, thereby changing the distance between the active roller 11 and the driven roller 12.

[0045] One end of the active roller 11 is connected to the shaking handle 10, and the shaking handle 10 is located outside one of the movable pressure blocks 06; the other end of the active roller 11 is connected to the movable pressure block 06 through the bearing 13, and the active roller 11 and the bearing 13 are also clearance-fitted; rotating the shaking handle 10 can rotate the active roller 11.

[0046] In this embodiment, the screw assembly includes a screw rod 08, a butterfly nut 09 and a guide column 07. The screw rod 08 is threadedly connected to the movable pressure block 06, the mounting block of the movable support seat 05, and the vertical surface of the support base 01. The screw rod 08 is arranged perpendicular to the horizontal plane; the butterfly nut 09 is arranged on the screw rod 08, and rotating the butterfly nut 09 can change the height of the movable pressure block 06 (that is, the distance relative to the movable support seat 05 and the support base 01) to adapt to workpieces of different sizes and hardness.

[0047] The guide post 07 is parallel to the screw rod 08. One end of the guide post 07 is fixedly connected to the mounting block of the movable support seat 05 and the vertical surface of the support base 01, and the other end passes through the movable pressure block 06. The guide post 07 plays a guiding role in the movement of the movable pressure block 06, so that the movable pressure block 06 can move smoothly. In this embodiment, each movable pressure block 06 is equipped with two guide posts 07, and the guide posts 07 are arranged at the ends of the movable pressure block 06, which does not affect the installation of the screw rod 08, the active roller 11 and the driven roller 12.

[0048] Rotating the butterfly nut 09 and the adjusting rod 04 can put the device into a rolling state or a natural state. In the natural state, the active roller 11 does not apply a pressing force to the steel plate 14; in the rolling state, the steel plate 14 is pressed between the active roller 11 and the driven roller 12; pressure is applied to the steel plate 14 through the relative movement of the active roller 11 and the driven roller 12, thereby changing the shape of the steel plate 14.

[0049] In this embodiment, appropriate rollers are selected according to the specifications and sizes of the steel plate 14 to be processed to ensure the correct position of the steel plate 14 during the rolling process to avoid deflection and deformation; the adjustment rod 04 is rotated to a suitable position, the steel plate 14 to be processed is placed between the active roller 11 and the driven roller 12, and the handle 10 is manually operated to gradually contact the steel plate 14 and apply pressure. As the rollers rotate and move, the steel plate 14 is gradually rolled into the desired shape. The entire process requires the butterfly nut 09 to be continuously rotated according to the forming state of the steel plate 14 to control the pressing force and the handle rotation speed to ensure the quality and accuracy of the forming.

[0050] This embodiment can accurately control the forming process of the steel plate 14 through manual control to achieve high-quality forming effects; due to its manual operation characteristics, it can accurately complete the processing of special specifications and small quantities of diversified products.
