Problems solved by technology

The existing roof panel forming method is mainly based on cold rolling, which is to send the steel plate coil into the forming equipment, and press the roof panel through a series of forming rollers of different shapes. The roof panel produced is only a straight plate, which cannot meet the modern Streamlined and Multi-Surface Design Requirements for Buildings
At present, in order to achieve a satisfactory streamlined and multi-curved roof effect, streamlined and multi-curved metal roof panels are generally made through processes such as cutting, splicing, and welding. materials, low production efficiency

Embodiment 1

[0025] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the forming equipment of the roof panel of the present invention includes a positioning platform 1, a feeding roller group 2, a forming roller group 3, a forming roller lifting device 4, a numerical control device for controlling the forming roller lifting device 4, and a discharging roller group 5 , reader 6, described forming roller group 3 comprises upper roller, lower roller, and described forming roller lifting device 4 is connected with described lower roller, and described lower roller comprises three forming wheels 31,33,35, three The outer diameters of the forming wheels 31, 33, 35 are not completely the same, wherein the two forming wheels 31, 35 on both sides have the same radius, and the radius of the forming wheel 33 in the middle is larger than that of the two forming wheels 33 on both sides. The radii of the forming wheels 31, 35 are large, and the roller shaft of the upper roller is fixed, ...

Embodiment 2

[0032] Such as figure 1 , Figure 5 , Figure 6 , Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that the forming wheel 33 in the middle of the forming equipment of the roof panel in this embodiment has the same radius as the forming wheel 35 on the right side, and the radius of the forming wheel 35 on the left side is the same. The radius of the forming wheel 31 is larger than that of the two forming wheels 33, 35 in the middle and the right side.

[0033] The structure of the roof panel manufactured by the forming equipment and method of the roof panel of this embodiment is as follows: Figure 6 , Figure 7 As shown, that is, the horizontal dimension of the roof panel is unchanged, but it is curved in the length direction.

Embodiment 3

[0035] Such as figure 1 , Figure 8 , Figure 9 , Figure 10 As shown, the difference between this embodiment and Embodiment 1 is that the two forming wheels 31 and 35 on both sides of the forming equipment of the roof panel in this embodiment have the same radius, and the radius of the forming wheel 33 in the middle is the same. The radius is smaller than the radius of the two said forming wheels 31 , 35 on both sides.

[0036] The structure of the roof panel manufactured by the forming equipment and method of the roof panel of this embodiment is as follows: Figure 9 , Figure 10 As shown, that is, the transverse dimension of the roof panel gradually increases from the middle to both ends.

[0037] In the same way, changing the outer diameters, wheel bases, and lifting tracks of the three forming wheels 31, 33, and 35 also has other different combination methods, and different combination methods can produce metal plates with different arcs and curvatures. The examples...

Abstract

The invention discloses equipment and a molding method for fabricating multi-curved surface and streamlined roof plate with simple and convenient technical process, material conservation and high production efficiency. The process of the invention is divided into material feeding, molding and discharging. During the molding process, a numerical control device calculates a lifting movement track of a molding roller group (3) according to input data and controls a lifting device (4) of the molding roller to move the molding roller group (3) according to the movement track and extrude and press a metal plate (8) to different extents to obtain shapes with different curvatures. The equipment comprises a spacing platform (1) used for feeding, a feeding roller group (2), the molding roller group (3), the lifting device (4) of the molding roller, a discharging roller group (5) and the numerical control device; the molding roller group (3) comprises an upper roller which comprises three grooves (32, 34 and 36) and a lower roller which comprises three molding wheels (31, 33 and 35) with different outer diameters; the molding wheels (31, 33 and 35) are respectively matched with the three grooves (32, 34 and 36). The invention is applicable in the slab molding field.

Description

technical field [0001] The invention relates to a forming method and equipment for a board, in particular to a forming method and equipment for a roof panel. Background technique [0002] Roof panels are the main structural components commonly used in the field of steel structure buildings, and are mainly used in composite roof systems. The existing roof panel forming method is mainly based on cold rolling, which is to send the steel plate coil into the forming equipment, and press the roof panel through a series of forming rollers of different shapes. The roof panel produced is only a straight plate, which cannot meet the modern Streamlined and multi-surface design requirements for buildings. At present, in order to achieve a satisfactory streamlined and multi-curved roof effect, streamlined and multi-curved metal roof panels are generally made through processes such as cutting, splicing, and welding. materials, low production efficiency.
