How to effectively improve the processing level of sheet metal processing


Sheet metal processing, generally by stamping some metal sheets by hand or die to plastically deform to form the desired shape and size, and further forming more complex parts by welding or a small amount of machining; sheet metal processing has been Our lives are closely related. It is an imperative development trend to improve the processing level of sheet metal processing and produce more high-quality sheet metal parts.

So, how to effectively improve the processing level of sheet metal processing? In order to effectively improve the processing level of sheet metal processing, we can start from the following points:

First, strengthen the research of sheet metal processing technology.

The plasticity of sheet metal processing allows the sheet metal processing to grow rapidly. The advantage of sheet metal processing compared to other processing techniques is plasticity. There are three types of sheet metal forming: cold, warm and hot; three researches on sheet metal forming plastic forming are bound Row:

1. Discuss various solutions of mechanics in the plastic forming process of sheet metal processing, analyze the stress and strain distribution rules in the deformation body, and determine the deformation force and deformation work, so as to reasonably select the tonnage of the equipment and the strength of the mold.

2. Study the rules for changing the strain and dimensions of the members during the plastic forming process of sheet metal processing, and select suitable blanks and reasonable center blank shapes to optimally reach the desired shape of the members.

3. Study the effects of sheet metal processing conditions such as temperature and strain rate effects on the resistance of metal plastic working and the methods of improving metal resistance and reducing resistance to obtain components with outstanding functions. The plastic analysis methods for metal forming mainly include principal stress method, slip line method, upper limit method, finite element method, etc.; and the commonly used test methods include visual plasticity method and dense grid moiré method.

Second, the standardization principle of standardized sheet metal processing.

1. (Sheet cabinet sheet metal processing) It is not allowed to place tools, fixtures and workpieces on top of the lathe and above the gearbox. Concentration is needed during construction. You can't be tired, chat, multiplayer, and smoking.

2. In order to prevent the chipping of the chipping, it is necessary to place a transparent baffle in a suitable place.

3. The strip-shaped chips appearing during cutting and the long-cut chips of sheet metal processing need to be solved as soon as possible by using hooks.

4. It is suitable to use the gauze to grind the appearance of the parts. It is necessary to move the tool to a safe place, and be careful not to let the hands and clothes touch the appearance. When grinding the hole inside, you can't use your finger to support the gauze. You need to use other items instead, and the speed should not be too fast.

Third, do a good job in the cleaning and processing of sheet metal processing.

1. First, rinse the surface of the sheet metal case with water to remove dirt from the surface.

2. Then wipe with soap, liquid detergent or water with 5% ammonia solution.

3. Rinse carefully with water again.

4. Finally, we will dry the water stains left on the outside of the cabinet cabinet. In the process of drying, we need to scrub in the same direction for the cleaning. After the scrubbing, let them dry naturally.

In the process of sheet metal processing, if the above three aspects are done well, it basically equals the basic work of sheet metal processing, thus effectively improving the technological level of sheet metal processing; in order to produce high quality and reasonable sheet metal processing. product.
