Sheet Metal Parts Design

In order to ensure the material utilization rate and the minimum number of die changes in bending, the thickness specifications of plates on the same structure shall not exceed three at most. For structures with high strength requirements, the method of pressing reinforcement on thin plates can be adopted;

It should be avoided that the unfolding size of parts is equal to the outline size of raw materials: the shape of plates supplied in the market is not square. If the unfolding size is equal to or very close to the outline, there is no allowance for the whole square, and the product size after direct processing has errors, which will affect the installation and use.

For non-sprayed plates with decorative surface requirements, the decorative surface and grain direction shall be considered in combination with the plate materials. For any purpose, the plate with decorative surface shall be used and the grain direction shall be required. For non-exposed parts, the processing process shall be protected from scratch, and the welding joints shall be treated after welding. The processing volume is large. Therefore, in order to ensure the utilization rate of materials and reduce unnecessary processing, The direction of decorative surface or other materials without decorative surface can be ignored.

Semi-automatic Sheet Metal Production Line

At this stage, most of the production in the chassis and cabinet industry uses single machine production, including laser cutting machine, plasma cutting machine, plate shears, CNC punching, bending machine, oil press, riveting machine, argon arc welding machine, electric welding machine, laser welding, surface treatment equipment, etc. these equipment require a lot of labor and have low production efficiency. With the increasing labor costs and the increasingly standardized safety protection regulations, the chassis and cabinet industry urgently needs to change the current situation. Intelligent storage warehouse of sheet metal + automatic feeding + laser cutting machine + automatic cutting and automatic dividing. The other side of the warehouse can be punched by numerical control. It is best to use laser compound punching (manual cutting), automatic grinding, bending machining center (bending by robot), and another numerical control bending machine is equipped, fol...

Precision Machining of Sheet Metal Parts

The main ways to realize the precision machining of parts are: using high-precision machining machine tools to process high-precision parts; Use error compensation technology to improve the machining accuracy of parts. Mechanical processing mainly includes manual processing and numerical control processing. “Sheet metal is a comprehensive cold working process for sheet metal (usually less than 6mm), including shearing, punching / cutting / compounding, folding, welding, riveting, splicing and forming (such as automobile body) Etc. Its remarkable feature is that the thickness of the same part is consistent. The products processed by the sheet metal process are called sheet metal parts . The way to distinguish whether a part is a sheet metal part or a machined part on a mechanical drawing is to see whether the thickness of the part is consistent. The thickness of sheet metal parts is consistent, while the thickness of machined parts is inconsistent. ...

Process Analysis of Sheet Metal Structure Design

Sheet metal processing is a comprehensive cold working process for sheet metal, including shearing, punching, cutting, folding, welding, riveting, etc. its remarkable feature is that the thickness of the same part is the same. Sheet metal is generally some sheet metal through manual or die stamping to produce plastic deformation to form the desired shape and size, and can further form more complex parts through welding or a small amount of machining. For example, chimneys, iron buckets, oil tanks, oil pots, ventilation pipes, funnel-shaped, etc. commonly used in families, as well as electrical cabinets, shells of various special equipment, computer cases, automobile shells, etc., are all sheet metal parts. There are no specific structural requirements for sheet metal parts, which are generally designed according to the needs of products. On the premise of meeting the functions of products, the designed structure should be easy to process, low cost and beautiful. For...
