How to reduce the loss in the fabrication of automotive sheet metal parts?
How to prevent welding deformation in automobile sheet metal fabrication: 1. On the premise of ensuring structural strength, the number of welds should be minimized. 2. Select a reasonable form of joints and grooves. Welds should be avoided to be concentrated in a small area, and parallel welds should be minimized. 3. Arrange the welds symmetrically and as close to the centerline as possible. 4. When designing the welding structure, it should be considered that the tool holder can be easily used in production to help prevent welding deformation. Decompression quenching in sheet metal fabrication is to reduce the liquid surface pressure of the quenching medium, thereby prolonging the vapor film stage, and the cooling rate in the high temperature area decreases, so that the cooling rate of each part of the part is uniform.
How to reduce the loss during sheet metal fabrication
- 1. The hardware models, specifications and functions selected for sheet metal fabrication and production must comply with standards and regulations, as well as the selection of PVC doors and windows.
- 2. Fastening screws need to be installed in the metal lining, and the thickness of the lining layer at the two fastener sites is larger than that of the hardware.
- 3. Regularly install metal stamping parts to prevent rust and corrosion.
- 4. Window entry door lock handle assembly in sheet metal fabrication production. To make sure it’s correct, the switch needs to be flexible.
- 5. Sliding windows are double pulleys, wide or double-glazed doors and windows more than one meter.
- 6. The sliding hinge is made of stainless steel.
- 7. The warning light is turned off during use.
