The important points for the bending test of sheet metal processing

Angelina Dong original 2015-10-13 13:03:51
We will use in the sheet metal processing to the sheet metal bending process, the following please Houdry sheet metal fabrication factory To introduce the main points of the sheet metal processing bending test:
1. Look at the drawings confirmed one corner is the first view, or the third Angle of view, by adopting the perspective drawing drawings confirm the bending direction is correct.

2. Verify material drawings, thickness is correct, according to the size of drawing test each bend, ensure the tolerance size, size of hole to the edge.
3. Check the bending knife conform to product requirements, if not any surface treatment, A1 surface are not allowed to have bad defects such as embossing, indentation, scratch, B in the face of bad defects such as embossing, indentation, scratch has certain limitation, executed according to the requirements of customers or factory standard.
4. For electroplating products, material surface can not have scratch, scratch, embossing, indentation, rust and other adverse.Each product must be separated from the film with clean, clean, and rust-proof oil brush to clean.
5. With electrolytic plate, aluminium zinc plate, aluminum plate processing and don't make any deal with the surface of the product, the surface can not have scratch, scratch, indentation, stamping, machining product requires separate paper, and stacking, put should conform to the requirements of the operation, can't put too much, will lower compressive deformation.
6. After drawing back in the bending process of aluminum products, product surface can not have scratch, scratch, indentation, stamping, machining finished using plastic bags, or pearl cotton, bubble wrap packing material such as protection, in case of workpiece scratch each other in the process of operation.
7. If the workpiece surface is scratch, scratch, indentation, embossing, please executed according to the requirements of customers or factory standard of judgment.
8. For batch processing of products, should sampling every 0.5 hours to the scene of the processing, to prevent mold wear loose, positioning rail, operators to modify programs of batch harmful by bit is not straight and so on.
9. Bending when final inspection, the principle of first inspection personnel should be staggered to each other, that is the first inspection and final inspection cannot be inspection by the same person (in case of inertia cause processing error check out), final inspection, sampling in strict accordance with the standards for sampling.Sampling should be dispersed sampling, make the sample is representative.
