How to prevent damage to metal stamping parts and standard accuracy

The stamping parts have high specification accuracy when in use. Together with the uniform specifications of the mould parts, they have better interchangeability. It can meet general equipment and usage requirements without further machining. Stamping parts are manufactured by stamping under the premise of low material consumption. The parts are light in weight and rigid. After the sheet metal is plastically deformed, the internal arrangement of the metal is improved, which improves the strength of the stamping parts. In the stamping process, because the surface of the material is not damaged, the stamping parts have a good surface quality and a smooth and beautiful appearance, which provides convenient conditions for surface painting, electroplating, phosphating and other surface treatments. How to prevent the damage of metal stamping parts? 1. The type, specification and function of the hardware fittings should comply with the current specifications and relevant regulations, and match the selection of plastic steel doors and windows. 2. For sliding windows with a width of more than 1 meter, or double-glazed doors and windows of equipment, double pulleys should be installed, or roll pulleys should be used. 3. Aluminum alloy materials should not be used for sliding support hinges, but stainless steel materials should be used. 4. For hardware with fastening screws, it is necessary to install a metal lining board. The thickness of the lining board should be at least twice the pitch of the fasteners. It must not be fastened to plastic profiles, and non-metal linings must not be used. 5. Hardware accessories should be the final equipment, door and window locks, handles, etc. should be assembled after the window and door leaves are put into the frame to ensure that the orientation is correct and the switch is active. 6. Pay attention to maintenance after hardware stamping equipment to prevent rust and corrosion. In daily use, lightly close and lightly open to prevent hard closing and hard opening, which may cause damage. No noise. With the current nylon wheels, not only does it push and pull without noise, but it is also smoother and lighter. The service life is not shorter than that of the above various pulleys. To make (doors) and windows operate normally and smoothly, they must provide (doors) and windows. Choose a high-quality pulley. On the surface, the inferior pulley has a rough workmanship, no smoothness, inflexible sliding, small and light.
