Sheet metal processing plays an important role in mechanical engineering in China. With the improvement of sheet metal processing technology, the requirements for the level of sheet metal processing technology are becoming increasingly high. However, there are still processing difficulties in sheet metal processing technology, which directly affects the speed of advancement of sheet metal processing technology in China. Reasonably improving sheet metal processing technology is the key to the sheet metal industry. The article analyzes the difficulties in sheet metal processing technology and proposes corresponding improvement measures.
Sheet metal processing is an important processing technology in China's machinery industry. The requirements for sheet metal processing technology are relatively high, and traditional sheet metal processing technology can no longer meet the existing sheet metal processing requirements. There is a certain gap between the processed sheet metal and the current actual requirements. Therefore, it is necessary to improve the sheet metal processing technology in order to meet the requirements of sheet metal processing in today's market. With the continuous advancement of technology, sheet metal has encountered problems in processing technology. Only by solving the causes of these problems can the level of sheet metal processing technology be improved and breakthroughs in sheet metal processing technology be achieved.
Difficulties in sheet metal processing technology
Sheet metal processing technology is the process of manually or using molds to shape and dimension some metal sheets into the desired and required shape. Through welding or small mechanical processing, it forms more complex shapes. For example, in households, fuel tanks, iron pipes, ventilation ducts, iron pots, funnels, chimneys, elbows, and various equipment casings are all sheet metal components. Sheet metal components do not have a fixed structural form. When designing products, the premise of production function should be met: the designed structure should achieve aesthetic appearance and low production cost. Sheet metal components are designed according to specific needs, and different structures require different forms to be designed. In summary, the design of sheet metal components is not fixed and unchanging, but needs to change with the product, which is the difficult problem faced by sheet metal processing technology.
2 Measures for Improving Sheet Metal Processing Technology
The problems encountered in actual sheet metal processing technology can be analyzed from the following points and improvement measures can be taken.
2.1 Material selection for sheet metal processing
Sheet metal processing is generally used for the casing of equipment, so the selection of sheet metal is very important. It is necessary to choose appropriately and conveniently during processing, while also reducing the cost of processing while ensuring strength.
When processing materials in the same structure, it is necessary to ensure the utilization rate of the materials. The maximum number of materials with the same specification and thickness of the board should not exceed three. This requires high utilization of materials during processing and cannot be wasted. For sheet metal structures with high strength and requirements, the method of thin plate reinforcement can be used to achieve the goal.
The sheet metal processing materials supplied in the market sometimes do not meet the requirements in terms of appearance. For example, the unfolded size of the parts produced by sheet metal processing is not equal to the outer contour size of the raw material, which will affect their installation on the material.
Some materials do not require external material spraying on the decorative surface, but need to be considered in terms of the decorative surface and texture of the board. If it is not exposed to the outside, the material does not need to be strictly required; But when the material needs to be exposed to the outside, strict requirements must be placed on the texture of the material, and the outer material cannot be scratched during processing. So it is necessary to ensure that unnecessary damage is reduced and material utilization is improved during sheet metal processing.
2.2 Hole structure design and processing
Some sheet metal processing requires drilling, which requires designing the holes. In addition to meeting the requirements of the product, it should also be easy to process without affecting the later stages of sheet metal processing and its beautiful appearance. (1) When processing square holes to the root, avoid stretching the sheet metal after processing, which may cause deformation of the holes. If manual punching is performed during sheet metal processing, it will increase the difficulty of the sheet metal processing process.
(2) When sheet metal parts require threaded holes, various methods can be used to achieve this, as shown in the table.
(3) Design of curved structures. The specific requirements for the smallest inner diameter edge in bending.
3 Conclusion
There is an inseparable relationship between sheet metal processing technology and modern production. In today's rapidly developing sheet metal technology, we should understand and innovate its processing technology and improvement measures, so that sheet metal technology can have better development. Through the explanation and analysis of the above aspects, reference targets have been provided for future sheet metal processing technology. The direction that the mechanical industry hopes and needs to move forward is to achieve better levels of sheet metal components designed and processed while meeting product production requirements. The progress of sheet metal processing technology today marks the direction of the national machinery manufacturing industry's advancement, constantly improving itself in development and allowing sheet metal processing technology to better improve itself in development. This is the driving force for progress.
