In the industrial production of Metal Stamping Parts, a variety of presses and special tools installed on the press are used to make metal materials into parts or products of desired shapes through pressure. Such special tools are collectively called hardware molds.
The service life of metal molds is related to many factors such as mold structure design, mold steel selection, heat treatment, surface treatment, machining grinding, wire cutting technology, stamping equipment, stamping materials and processes, mold lubrication, poor level of maintenance and repair. Among the various factors that cause mold failure, mold structure is unfair, material selection is about 20%, improper heat treatment is about 40%, process problems are about 20%, equipment problems, smoothness and other factors account for about 20%.
Pay attention to maintenance after installation of metal stamping parts to prevent rust and corrosion. In daily use, lightly close and open gently to prevent hard closing and hard opening, causing damage. The following is how to prevent metal stamping parts from being damaged: 1. For widths greater than 1 Meters of sliding windows, or double-glazed doors and windows, should be equipped with double pulleys, or use movable pulleys. 2. The sliding brace hinge shall not be made of aluminum alloy, but shall be made of stainless steel. 3. To install hardware with fastening screws, a metal lining must be built in. The thickness of the lining should be at least twice the tooth pitch of the fastener. Do not fasten to plastic profiles or use non-metallic linings. 4. The type, specification and function of the hardware accessories should conform to the current national standards and relevant regulations, and match the selection of plastic steel doors and windows. 5. Hardware accessories should be installed last. Doors and windows locks, handles, etc. should be assembled after the windows and doors are fanned into the frame to ensure accurate positions and flexible switching. 6. Pay attention to maintenance after installation of metal stampings to prevent rust and corrosion. In daily use, lightly close and lightly open to prevent hard closing and hard opening, causing damage. There is no noise, there is the current nylon wheel. It is not only no noise when pushed and pulled, but also smoother, lighter, and the service life is not shorter than the various pulleys above. To make the (door) and window normal, stable operation requires the (door) ) Choose a high-quality pulley from the window. Inferior pulley from the surface, the workmanship is relatively rough. There is no smoothness. Sliding is not flexible, small and light.
