Sheet metal fabrication, generally some metal sheet through manual or die
stamping to produce plastic deformation, the formation of the desired shape and
size, and can be further through welding or a small amount of mechanical
processing to form more complex parts; Sheet metal processing has been closely
related to our life. It is an imperative development trend to improve sheet
metal processing technology level and produce more high-quality sheet metal
So, how to effectively improve the sheet metal processing technology level? Kunshan Jiexiang believes that in order to effectively improve the level of sheet metal processing technology, we can start from the following points:
First, strengthen the research of sheet metal processing technology
Sheet metal processing plasticity so that sheet metal processing rapid growth, sheet metal processing compared with other processing technology advantage is plasticity, sheet metal processing plastic forming has three categories: cold, warm and hot; There are three research imperative for sheet metal processing plastic forming:
1, Discuss various mechanical solutions in the process of sheet metal processing plastic forming, in order to analyze the stress and strain distribution rules in the deformation body, and determine the deformation force and deformation work, in order to reasonably select equipment tonnage and die strength.
2, Sheet metal processing plastic forming process component strain and scale change rules, select the appropriate billet and reasonable center blank shape, in order to optimally reach the required shape of the component.
3, Temperature, strain rate effect, and other sheet metal processing conditions on the impact of metal plastic processing resistance and progress of metal tolerance and resistance, in order to obtain components with outstanding functions. The plastic analysis methods of metal forming mainly include the principal stress method, slip line method, upper limit method, finite element method, etc. The common test methods are the visual plasticity method and the dense grid moire method.
Second, the standard principle of standardized sheet metal processing
1, (chassis cabinet sheet metal processing) can not be the tool, fixture, and workpiece on the lathe and above the transmission above. You need to focus your mind when you're building. Do not be tired, chat, crowd, and have smoking control.
2. In order to prevent the chip from crashing into people, it is necessary to place a transparent baffle in an appropriate place.
3, In the cutting of the strip chip, sheet metal processing like a long chip, need to use the hook as soon as possible to solve, can not be pulled by hand.
4. When it is suitable for grinding the appearance of parts with gauze, it is necessary to move the tool to a safe place, and be careful not to let hands and clothes touch the appearance. When grinding the hole inside, you can not use your finger to support the gauze, and you need to use other items instead, and the speed is not too fast.
Third, do a good job of sheet metal processing and cleaning treatment
1. First, rinse the surface of the sheet metal case with water to remove dirt on its surface.
2, Then add soap, liquid detergent, or 5% ammonia solution of water to wipe.
3. Rinse carefully with water again.
4. Finally, we wipe the water stains remaining on the surface of the chassis and cabinet. In the process of drying, we scrub in the same direction in order to clean and let the appearance of the natural sun dry after cleaning.
In the process of sheet metal processing, if the above three aspects are done well, it is basically equal to tamping the basic work of sheet metal processing, so as to effectively improve the technological level of sheet metal processing; In order to produce high-quality and reasonable sheet metal processing products.
