Considerations and processes for sheet metal design

2023-07-20

Whether it is automotive shells, CNC machine tool protective covers, or computer cases, communication equipment and other products are inseparable from Sheet Metal, and with the increasing maturity of sheet metal processing technology, sheet metal shows a broader development prospect. However, sheet metal processing is a more complex work, not only involving a variety of process methods and parameters, but also including equipment principles and operating technology, so in order to ensure that the quality of Sheet Metal Parts meets the standard, in line with product requirements, it is necessary to discuss sheet metal design, in order to promote the healthy development of the sheet metal processing industry.

Sheet metal design

GZ has formed its own complete set of systems in sheet metal design and manufacturing to ensure the quality of sheet metal design and processing.

The steel frame is combined with a protective cover

In sheet metal design, we usually design mounting holes on the bed body, and use Allen screws above 8mm to fix, design a frame with a square tube with a cross-sectional area of at least 40mm×40mm, and install the machine tool protective cover on the steel frame in the form of "hanging cable up and down" (Figure 1), which can not only ensure firmness, but also facilitate disassembly and transportation.

Sheet metal design, processing process and precautions discussion

Panel design

GZ at the beginning of the design to consider the production reality, including the size of the sheet, the current use of more plate size is 1250mm×2500mm and 1500mm×3000mm, using a Laser Cutting Machine with a format of 3015 processing, so in the design must ensure that the plate to be processed in this size range, otherwise it will be processed separately.

Universal sheet metal

In the programming stage, a lot of offcuts will be generated, in order to improve the utilization rate of sheet metal, some general parts such as stiffeners or glass pressing strips can be programmed into the program to be processed, which not only improves the utilization rate of the Cutting Machine, but also consumes the offcuts and reduces material loss.
