Problems solved by technology

[0006] 2. Difficulty in making molds: With traditional manufacturing techniques, the louvers (sheets) are deformed after being pressed and formed, so the mold must have an anti-deformation allowance, and this allowance is obtained based on the experimental results
Therefore, the mold must be repaired after the mold is manufactured, and the technology of repairing the mold is complicated and the operation is difficult. If there is no experience, the mold may be sc

Embodiment Construction

[0016] Process flow: roll forming, punching.

[0017] 1. Rolling cold bending forming process:

[0018] 1. Make the upper and lower rows of rolling wheels similar in shape to the blinds (pieces). Each row has about 12 sets of rolling wheels (according to actual needs). The shape of the rolling wheels gradually changes from cylindrical to the shape of the blinds (pieces). , gradually cold-bending and continuous forming.

[0019] 2. In order to ensure the leveling and correct positioning of the roll material, two sets of positioning wheels and one set of leveling wheels are set at the front end of the rolling wheel to ensure that the relative position of the louver (piece) material and the rolling wheel is correct.

[0020] 3. At the end of the rolling wheel, set a set of shaping wheels and adjustment frames to ensure that the blinds (pieces) are formed correctly.

[0021] 4. Pre-customized steel strip coils with the same width as the shutter (piece) unfolded material.

Abstract

The invention relates to a rolling and cold-bending forming manufacturing method of window-shades for a steel structure, relating to the processing technology of metal pieces. The method adopts a rolling and cold-bending forming technology and is characterized in that an upper row and a lower row of rolling wheels are arranged on a rolling and cold-bending forming machine, and the shape of the rolling wheels are gradually changed into window-shades from cylinders from the inlet end to the outlet end of the rolling and cold-bending forming machine; and steel belt coiled materials having the same width with the unfolding materials of the window-shades are sent to the inlet end of the rolling and cold-bending forming machine and are cut off at the outlet end by hydraulic shears. The invention simplifies production routine, greatly enhances production efficiency, improves work efficiency at least over 8 times, abandons manufacture of complex dies, enables the production to be adjusted with the change of materials, enables the quality of products to be stable and reliable and greatly reduces cost.

Description

technical field [0001] The invention relates to the processing technology of metal parts. Background technique [0002] The heat exchange system (triangular) steel structure is mostly used in cooling systems such as power plants, and the louvers (sheets) used in this structure are indispensable parts in the cooling system. It is made of steel plate of about 2mm, the length is usually about 2m, the width is generally about 220mm, and it is wavy. The cooling system of each power plant requires tens of thousands of pieces. Blinds (sheets) have high technical requirements and a large quantity requirement. It requires an angle error of 0.5mm and a flatness error of 2mm within 2m, which is a difficult point in the manufacturing process of the heat exchange system (triangular) steel structure. [0003] The manufacture of louvers (sheets) for heat exchange system (triangular) steel structure has a history of more than 50 years. A well-known foreign company has been using the tradit...
