Modern sheet metal processing, simply put, involves processing and handling metal, such as metal parts. In production practice, when people are producing metal parts, the processing of these parts all uses sheet metal processing. Shanghai sheet metal is characterized by its light weight, high strength, conductivity (suitable for electromagnetic shielding), low cost, and good mass production performance. It is widely used in electronics, communications, automotive, and medical device industries. For example, sheet metal is an indispensable component in computer cases, mobile phones, and MP3 players. Shanghai sheet metal processing is a key technology that sheet metal technicians need to master, and it is also an important process in the forming of sheet metal products. Sheet metal processing includes traditional methods and process parameters such as cutting, blanking, and bending, as well as various cold stamping die structures and process parameters, the working principles and operation methods of various equipment, and new stamping technologies and processes. The processing of metal sheets for parts is called sheet metal processing.
In sheet metal processing, the general processes are roughly the same, but there are also differences. This requires workers to reasonably arrange the sequence of sheet metal work based on their work experience. According to the process flow, the indispensable steps in sheet metal processing include: stamping metal raw materials; stamping metal raw materials using machines such as punch presses; alignment in the sheet metal; stamping machine parts to make them into specific models, ensuring a positive amount is paid to the sheet material when using a punch press; precise positioning; and a series of operations such as riveting, bending, and welding metal sheets.
In addition, sheet metal processing is currently a hot topic, so what are the processing prices? Are prices higher than before? This analysis of sheet metal processing prices by pressing and sheet metal processing companies is provided for your reference.
The cost of sheet metal processing includes:
1. Transportation costs: This is amortized into the cost of the product.
2. Management costs: This is divided into two parts: factory rent, utilities, and financial expenses.
3. Materials: This represents the net material cost required by the drawings = size x density x unit price + batch variation rate loss.
4. Cost of standard parts and accessories: This refers to the cost of standard parts required by the drawings.
5. Sheet metal processing procedure costs: This means the cost of each procedure of the manufactured equipment.
6. Packaging Fee: Depending on the product and packaging requirements, the cost varies, generally ranging from 20-30 RMB per cubic meter.
For NC sheet metal processing, there are several processing methods:
(1) Single stamping, including: arc distribution, mesh holes, etc.
(2) Continuous punching in the same direction, using multi-processing multi-directional continuous stamping dies with overlapping in the same direction, is particularly suitable for processing elongated holes. Suitable multi-directional continuous stamping has small dies to large holes.
(3) Silk processing, using small round dies and small steps for continuous arc punching.
(4) Single forming or continuous forming process is based on the nature of the die, first performing shallow stretching to form the sheet metal. However, if the forming size is larger than the die size, a continuous forming process is required.
(5) Array forming. This method is suitable for processing multiple workpieces on a large plate. The workpiece types can be the same or different.
