                                What is the difference between sheet metal processing and precision processing?

Precise sheet metal processing is also sheet metal processing. The two are actually a concept. The only difference is precision. The processing precision of sheet metal parts is greatly improved from traditional manual workshops to equipment processing. But to achieve precision sheet metal processing, there is still a lot of work to be done. What is the difference between sheet metal processing and precision sheet processing? The following editor of Zhongyilong will introduce to you:

1. Machining accuracy:

2. 

The precision of sheet metal processing is generally between 0.2~1mm. The precision of precision sheet metal processing is generally less than 0.2mm.

2. Processing technology:

General sheet metal processing uses traditional processing equipment such as ordinary punches and angle cutters to achieve the shape. It is usually processed for batch products, and the accuracy cannot be guaranteed. Some complex processes are difficult to achieve. It adopts high-precision numerical control sheet metal equipment, which is suitable for small batch product processing. It has the characteristics of short processing cycle, high precision and good consistency.

The main factors affecting the accuracy of sheet metal processing are processing equipment and sheet metal unfolding dimensions. For metal plates, more precise blanking dimensions are required, and more professional plate unfolding techniques are required.
                                         

Cold stamping process specification and drawing use

1. Shearing class: the first process in the sheet metal workshop. According to the content of the blanking process of the cold stamping process, the coil is uncoiled according to the cold stamping process specification, and the thin steel coil is cut according to the cold stamping process specification. The tailor must pay attention to checking the "four elements" on the board when cutting the material: board thickness, length, width, and oblique length. Only the parts that meet the above-mentioned four element size requirements are qualified plates. Cutting-off in the cutting team mainly provides blanks for punching and CNC punching. 2: Stamping class: using punches, hydraulic presses, and cold stamping dies to produce sheet metal parts. Punch operation guidance.

This book is a cold stamping process specification. At the same time, be consistent with the diagram. CNC course: Use CNC punching machine and CNC bending machine to make sheet metal. Instruct students as shown in the picture.

Produce. The operating instructions are also cold-punching process regulations. Four: Spot welding class: use a spot welding machine to spot weld different parts into parts. Manage household machines. Electric Welding Course: Use electric welders and spot welders to weld different parts together to make components. Lead underwriter.
                                  

Machine made. 6: Logistics distribution center: responsible for transferring metal plate parts from one place to another. 7. Warehouse processing: The final product enters the sheet metal warehouse first, and then is sent from the warehouse to the assembly plant or its assembly plant.

Matching with the workshop. The above is a brief description of each team in the sheet metal workshop
