During the production process of solar photovoltaic support, the wrinkled board may be scrapped, which not only increases the production cost, but also causes waste of raw materials, which needs to be analyzed and controlled.

However, the causes of wrinkling solar PV mounts in the production process are:

1. Insufficient BHF, inappropriate clamping gap faces the problem of internal and external tightness.

2. Excessive engine oil or too frequent brushing frequency, or improper position of brushing teeth.

3. The test blank is too soft, low-strength material, the blank size is too small, and the material is HID.

4. Rough positioning is unstable, resulting in local material pooling, improper occlusal surface shape, resulting in uneven walking feeding.

5. Improper stamping direction.

The measures to control the wrinkles of solar photovoltaic support are as follows:

1. Under the view state of solar photovoltaic support crepe, even if there are wrinkles in the surrounding plates, it is judged that the clamping force is less than that, and it can be removed as the nip force gradually increases. When stretching the cone and hemispherical members should be increased to increase the inner diameter of the inner plate to remove the drawbead tensile stress. Adopt the principle of loosening after tightness to get rid of the problem of looseness outside tightness.

2. For lubricating oil, the work of the oil brush should be carried out in accordance with the system requirements of the rules, so as to ensure the correct position of the oil brush and the oil brush, and avoid causing wrinkles.

3. The part blank is too soft without affecting the vehicle requirements, ensuring the quality of the parts and avoiding wrinkling of the solar photovoltaic bracket.

4. Improve positioning, plus pre-bending steps, if necessary, to ensure that web meandering does not occur when pressing parts. Change the shape of the surface pressure of the material to ensure the quality of the parts, avoiding that the surface shape of the nip does not move, resulting in uneven walking feeding.

5. The inappropriate direction of the pressing process on the panel should be designed using simulation software early to ensure the pressing direction of the panel. When the panel has higher quality requirements, it is necessary to redevelop the mold and analyze the adjustment of the pressing direction.
