How to Improve Quality During Sheet Metal Machining?

With the development and progress of society, people are becoming more and more proficient in the application of professional sheet metal fabrication. The sheet metal machining market is not only concentrated in this industry but also has a place in the automotive and other industries. In addition, machinery manufacturing, communications, and other industries will involve sheet metal machining. In recent years, the development of professional sheet metal machining in these industries has also been remarkable.


Ⅰ. Innovations in professional sheet metal fabrication


Cold working usually refers to metal cutting, that is, the use of cutting tools to remove excess metal layers from metal materials (blanks) or workpieces, so that the workpieces have a certain shape, dimensional accuracy, and surface roughness.


There are many steps in professional sheet metal fabrication such as turning, drilling, milling, planing, grinding, broaching, and so on. When forming metal, professional sheet metal work hardening can be used to increase the hardness and strength of the workpiece, but it will reduce the plasticity. Cold processing is suitable for processing metal parts with small cross-sectional dimensions and high processing dimensions and surface roughness requirements.


Ⅱ. How to improve the quality of sheet metal machining?


1. The experience and technology of the operator affect the bending accuracy. When pushing the stopper, the force of the worker is too large or too small, resulting in a positioning gap or bending of the plate, which affects the bending dimensional accuracy. The bending speed of the worker is not synchronized with the speed of the machine tool, which will cause the bending angle to be too large or too small.


Solution: Sheet metal machining and bending workers should be skilled and experienced, and do not frequently replace operators.


2. The quality of the material affects the accuracy of the bending dimension, and the thickness of the material directly affects the bending coefficient and bending accuracy.


Solution: Purchase goods from large steel mills and strengthen the inspection of thickness dimensions. The different mechanical properties of sheet metal machining materials will also affect the bending dimensional accuracy.


3. The bending coefficient affects the accuracy of the bending size, and the bending size of the sheet metal machining has been determined when the drawing is unfolded. In the expanded view, the bending coefficient is a key factor in determining the bending size. The calculation of the unfolded drawing is not accurate, which directly affects the dimensional accuracy of the sheet metal bending.


Solution: The sheet metal machining technicians are familiar with the principle of sheet metal unfolding, and can accurately determine the accurate bending coefficient according to theory and practice.
