What Do You Need to Know Before Sheet Metal Processing?

As the application of sheet metal processing becomes more and more extensive, the design of sheet metal parts has become an important part of the product development process. Mechanical engineers must be proficient in the design skills of sheet metal parts, so that the designed sheet metal can meet the requirements of the product. It can meet the requirements of function and appearance, and can make the stamping die easy to manufacture and low in cost.

Generally, when performing sheet metal welding processing, it is necessary to understand some precautions, and then improve the yield of the product. And how to understand the problems that need to be paid attention to when processing sheet metal? Let's take a look below.

Ⅰ. Preparation before sheet metal processing and welding

1. Welding labor protection products must be prepared, and sheet metal processing, welding equipment, welding rods, etc. should be checked to see if they meet the specified requirements and whether there are any problems.

2. The rust, grease and moisture on the weldment should be removed and cleaned.

Ⅱ. The basic size of the welding seam groove of sheet metal processing

Weld grooves should be reasonable, so as to ensure dimensional accuracy and reduce welding deformation.

Ⅲ. Sheet metal processing parameters

The welding process parameters mainly include electrode diameter, welding current, welding voltage and welding speed.

Ⅳ. Understand the structure of sheet metal processing and welding

1. The electrode should be able to ensure that it enters the welding area, and it should be inclined at 45 degrees.

2. During welding, continuous welding of long seams is not allowed, and alternate intermittent welding should be performed to avoid thermal deformation, which will then affect the welding quality.

Ⅴ. Common equipment for sheet metal processing

Professional sheet metal processing refers to the technology of processing plates with uniform thickness, including traditional cutting, blanking, bending and forming and other methods and process parameters, mainly cutting, punching, folding, welding and other processing steps.

1. Tapping means processing threaded holes, and the tool used is a tap. Manual tapping is done by installing the tap on the tap wrench. Motorized tapping is done by installing the tap on a drilling machine (or lathe). Taps are generally made of high-speed steel.

2. Threading means processing external threads, and the tool used is die. Manual threading is done by installing the die on the die holder. Motorized threading is done by installing the die on the drilling machine (or lathe). Dies are generally made of high-speed steel.

3. Threads generally include metric threads, inch threads and pipe threads (in which inch threads have been eliminated in national standards). Taps and dies also have the above three forms.

4. There are also various small power tools commonly used in sheet metal processing: there are many types of power tools, and their uses and usages are different. Commonly used small power tools include electric shears, electric grinding wheel saws, electric pipe cutters, electric drills, electric wrenches, electric angle grinders, etc. Pay attention to safety when using electric tools to prevent electric shock and mechanical injury accidents.

5. Air compressors are commonly used to drive pneumatic tools in sheet metal processing. Commonly used pneumatic tools include pneumatic hammer, pneumatic grinding wheel, pneumatic drill and pneumatic wrench. Pneumatic tools can only be used where there is an air compressor. Relatively safe to use with power tools.

6. Welding, cutting and lifting tools are also common tools for sheet metal processing.
