How to reduce the possibility of damage to metal stamping parts?

Hardware molds are used in industrial production to use various presses and special tools installed on the presses to make metal materials into parts or products of the required shape through pressure. These special tools are collectively referred to as hardware molds.

The service life of hardware molds is related to many factors such as mold structure design, mold steel selection, heat treatment, surface treatment, machining and grinding, wire cutting process, stamping equipment, stamping materials and technology, mold lubrication, poor maintenance and repair. Among the various factors that cause mold failure, unfair mold structure and improper material selection accounted for about 25%, improper heat treatment accounted for about 45%, process problems accounted for about 10%; equipment problems, slippery problems and other factors accounted for about 20%. After installing the metal stamping parts, pay attention to maintenance to prevent rust and corrosion. In daily use, lightly close and open to prevent hard closing and hard opening, which may cause damage. The following is an introduction to how to prevent metal stamping parts from being damaged:

1. The models, specifications and functions of hardware fittings should conform to the current national standards 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, it is advisable to install double pulleys or use movable elastic pulleys.

3. The sliding hinge shall not be made of aluminum alloy, but shall be made of stainless steel.

4. When installing hardware with fastening screws, a metal lining board must be installed inside, and 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-metallic linings must not be used.

5. Hardware fittings should be installed last, door and window locks, handles, etc. should be assembled after the window and door leaves are in the frame to ensure accurate position and flexible switching.

6. Pay attention to maintenance after installation of metal stamping parts to prevent rust and corrosion. In daily use, lightly close and open lightly to prevent hard closing and hard opening, which may cause damage. Without noise, there is the current nylon wheel. Not only does it push and pull without noise, it is smoother, lighter, and has a service life that is not shorter than the above various pulleys. To make (doors) and windows normal. Smooth operation, you must give (doors) ) Window choose a high-quality pulley. On the surface, inferior pulleys have rough workmanship. They are not smooth. They are not flexible to slide, and are small and light.
