The three major processes in sheet metal processing mainly include cutting, bending and welding spraying. The following is a detailed analysis of these three processes:1. CuttingCutting is the first key step in sheet metal processing. Its purpose is to obtain parts materials that meet the design requirements from large sheets. There are various ways of cutting, mainly including the following:Manual cutting: The traditional cutting method uses tools such as saws and scissors for manual cutting. This method is low-cost and suitable for small-batch production, but it is inefficient and difficult to ensure accuracy.CNC cutting: The use of computer control systems to automatically cut sheet metal has high precision and efficiency and is suitable for mass production.Laser cutting: Cutting with laser beams has high precision and high speed, and is suitable for sheet metal processing of various shapes.Plasma cutting: Cutting with plasma arcs has high speed and is suitable for sheet metal processing of various thicknesses, but the precision is relatively low.In actual operation, on-site workers will complete cutting through shearing machines or punching machines according to the unfolding diagram provided by the technical department. After the blanking is completed, the material number is usually marked on the surface of each piece of material with a marker pen for subsequent processing and identification.2. BendingBending is an important step in processing the sheet metal parts obtained from blanking into the desired shape. The bending and forming of metal sheets are carried out on a plate bending machine. The specific process includes:Place the workpiece to be formed on the plate bending machine.Lift the brake shoe with a lifting lever and slide the workpiece to the appropriate position.Lower the brake shoe onto the workpiece to be formed, and the metal is bent and formed by applying force to the bending lever on the plate bending machine.In the bending process, factors that need to be considered include tool selection, bending sequence, bending compensation, and bending interference. In order to improve efficiency and accuracy, some manufacturers will use bending programming software for auxiliary programming. However, most domestic CNC bending machines still rely on manual programming and experience operation.3. Welding sprayingWelding spraying is a subsequent step in sheet metal processing, which aims to combine multiple sheet metal parts together and give them an aesthetic and protective coating. This process usually includes the following steps:Welding: Combine multiple sheet metal parts into a whole by welding. There are various welding methods, including gas welding, manual arc welding, etc. During the welding process, it is necessary to ensure the firmness and beauty of the weld.Pre-spraying treatment: Before spraying, the sheet metal parts need to be cleaned, rust-removed, etc. to ensure the adhesion and durability of the coating.Spraying: Select the appropriate paint for spraying according to the design requirements. During the spraying process, it is necessary to control the thickness, uniformity and glossiness of the paint. For the body surface that needs to be repaired, special sheet metal spraying is also required to restore its appearance and performance.In short, the three major processes of cutting, bending and welding spraying in the sheet metal processing process are interrelated and inseparable, and together constitute the core process system of sheet metal processing. In actual operation, it is necessary to select the appropriate processing method and process flow according to the specific product requirements and production conditions to ensure the quality and production efficiency of the product.
Dongguan sheet metal processing is one of the important ways of metal processing today. The process can be divided into six processes in total, and the whole process is called sheet metal processing. With the rapid development of industry, the sheet metal processing industry has joined the urgent development process. With the improvement of science and technology. The technology of sheet metal processing has been improved. In the process of sheet metal processing, there are three important processing processes.Sheet metal processing Dongguan laser cutting. Cutting process is cutting. Cutting is the cutting of raw materials of sheet metal parts. In recent years, with the widespread application of laser cutting technology, it has become common to apply laser cutting technology in sheet metal processing. Because Dongguan laser cutting has the advantages of fast technology, low cost and fast programming. Dongguan sheet metal processing process 2: CNC bending. The bending shape is processed according to the processing requirements and changes in material quality. There are also many details. Another one is welding spraying. There are many kinds of welding technology, which can use different welding machines for weldments with different metal properties. For example, CO2 gas shielded welding, argon arc welding, etc.DongGuan Win-Leading Hardware Technology Co., Ltd. has developed for many years and specializes in hardware products such as hardware molds, stamping products, sheet metal bending, laser cutting, CNC processing, etc. with excellent manufacturing level and service attitude.
