Problems solved by technology

However, even if GFRP is suitable for processing free-form surfaces, the cost of traditional molds used for processing curved panels is still very high
The mold cost includes raw material cost, labor cost, mechanical cost and time cost, and the precision is lacking. If only one free-form panel is used to manufacture a free-form panel, there will be a huge problem of waste
Therefore, free-form curtain walls have always been difficult to realize well, and it is difficult to take into account both cost saving and architectural effects at the same time, and the building construction period is often very long
This problem also exists in the processing of traditional material free-form panels, and there has been no good solution

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0026] The invention proposes a manufacturing method of a mold for a curved panel, figure 1 Shown as its flow chart, in this embodiment, the curved panel is a GFRP building curtain wall free curved panel. The production method is specifically:

[0027] Firstly, select the GFRP surface model to be processed in the 3D software, and the GFRP surface model to be processed is the 3D model of the GFRP curved panel to be processed. Adjust the position of the GFRP surface model to be processed, and copy the surface outline of the GFRP surface model to be processed. Analyze the frame block of the GFRP surface model to be processed, and select the size of the mold raw material block corresponding to the modular size according to the size of the frame block. The raw material block selected in this embodiment is a cuboid, and its dimensions are: length ...

Abstract

The invention provides a fabrication method for a die of a curved plate and belongs to the technical field of civil engineering. The fabrication method comprises the steps that firstly, the size of anoriginal material block is selected according to a curved face model to be machined; then, the upper surface and the lower surface of the original material block are established, the curved face model to be machined is externally expanded to obtain an expanded surface, the part, outside the original material block, of the expanded surface is cut off, and a target curved face is obtained; the upper surface is cut according to the projection of the target curved face on the upper surface, the projection of the target curved face in the cut upper surface block and the part, not in contact with the outer contour of the curved face model to be machined, of the upper surface are removed, and the remaining upper surface is obtained; and a cutter path is obtained according to the remaining uppersurface, the target curved face and the lower surface, the original material block is cut, and the die is obtained. Foamed plastic can be adopted for the die material, the overall die fabrication costis low, efficiency is high, the obtained precision is far higher than that of engineering requirements, and application of the GFRP material to the building curtain wall can be effectively promoted.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and relates to a method for manufacturing a mold, in particular to a method for manufacturing a mold for a curved panel. Background technique [0002] Due to the requirements of building curved surfaces, the use of traditional curtain wall materials is limited. As a new building material, GFRP (glass reinforced plastic) has excellent performance compared with traditional curtain wall materials, especially the processing performance, so it is an ideal free-form curtain wall material. However, even if GFRP is suitable for processing free-form surfaces, the cost of traditional molds used for processing curved panels is still very high. The mold cost includes raw material cost, labor cost, mechanical cost and time cost, and the precision is lacking. If only one free-form panel is manufactured by one time, there will be huge waste. Therefore, free-form curtain walls have always been diffic...
