Analysis of Technical Difficulties and Improvement Measures of Sheet Metal Processing

1. Difficulties in sheet metal processing technology

Sheet metal processing technology is to make some sheet metal by hand or mold, so as to form the shape and size we want and require, through welding or a small part of mechanical processing, so that it forms a more complex shape. For example, in the family, the oil tank, the iron tunnel, the ventilation pipe, the iron pot, the funnel, the chimney, the elbow, and the shell of various equipment, etc., these are the components of sheet metal. Sheet metal members do not have a fixed structural form, in the design of the product, should meet the premise of production function: let the design of the structure to achieve beautiful appearance and low production cost principle. Sheet metal components are designed according to specific needs, and different structures need to be designed in different forms. In a word, the design of sheet metal components is not fixed, but to change with the change of products, which is the difficult problem faced by sheet metal processing technology.

2.Measures to improve sheet metal processing technology

1, Sheet metal processing material selection

Sheet metal processing is generally used in the shell of the equipment, so the selection of plates is very important. It is necessary to choose appropriate, convenient in processing, but also to reduce the cost of processing under the premise of ensuring strength.

In the same structure processing materials, to ensure the utilization of materials, the same specification of sheet thickness of the material can not be more than three kinds. This is to process the material to a high degree of use, can not be wasted. For that kind of high strength and high requirements of sheet metal structure, you can use the method of sheet metal reinforcement to achieve the purpose.

Sheet metal processing materials supplied on the market, its shape sometimes does not meet the requirements. For example, the expansion size of the parts processed by sheet metal is not equal to the external profile size of the raw material, which will affect its installation on the material.

Some materials do not need to be sprayed on the decorative surface, and need to be considered in the decorative surface of the plate and the texture of the plate. If it is not exposed to the outside, the material is not strictly required; But the material to be exposed to the outside, it is necessary to carry out strict requirements on the texture of the material, processing can not scratch the outside of the material. Therefore, it is necessary to ensure that unnecessary damage is reduced in sheet metal processing and the utilization rate of materials is improved.

2,Structural design of holes and holes

Some sheet metal machining needs to be drilled, which requires the design of the hole. In addition to making the product meet the demand, it is also convenient for processing, and does not affect the late process of sheet metal processing and its beautiful appearance.
