How to solve the most common factors of metal stamping parts maintenance and metal stamping damage?

Hardware stamping accessories products are indispensable tools in our daily life. Dongguan Hardware Products understands hardware related knowledge not only can help us to choose hardware stamping accessories, but also help us better maintain and use them, delaying its Service life, here are five commonly used maintenance methods. 1. It is not allowed to put high temperature tea cups or other high temperature items directly on metal stamping accessories furniture (glass, stainless steel, metal handles, etc.). Stepping racks, heat insulation pads, etc. should be used for isolation to avoid surface discoloration or blistering. 2. The hardware stamping parts should be kept clean. Water stains on the surface caused by accidental use should be wiped dry immediately after use, and the surface should be kept clean and dry. 3. Do not use sharp or hard objects to scratch the surface of hardware accessories. Use a damp cloth to scrub or damp a damp cloth with neutral detergent or detergent, and then wipe it off with water. 4. If the surface is severely stained or scratched, or burned by fireworks, lightly rub the surface with fine sandpaper (400-500), and then wipe it with a scouring pad. 5. Metal guide rails, hinges, hinges, etc. should be lubricated regularly to keep them bright and lubricated. Avoid hitting with hard objects or scratching the surface of hardware accessories with sharp objects, and avoid contact with hydrochloric acid, salt, bittern and other characteristics. The most common factor for the damage of metal stamping parts molds. Thermal stress is formed when high-temperature molten metal is filled. Dongguan hardware products cause the temperature gradient of the inner and outer layers of the metal stamping die to increase. Crack the mold surface, resulting in cracks. During the costing process, the mold temperature continues to rise. When the mold temperature is overheated, mold sticking occurs, and the moving parts fail to cause damage to the mold surface. A cooling temperature control system should be set up to keep the mold duty temperature within a certain range. During the die-casting process of the gold stamping die, the die temperature should be preheated to a certain temperature before the die is used. Chilling occurs when the ultra-low temperature molten metal is filled. The most common forms of mold damage are cracks and cracks. Stress is the main cause of mold damage. Thermal, mechanical, chemical, and operational shocks are all sources of stress, which can cause damage to the die-casting production mold: during die-casting production. Including mechanical stress and thermal stress. Cracks develop very quickly. The quality of rough forging in the mold processing and manufacturing process. Some molds have cracks after only a few hundred pieces are produced. The dendritic crystals, mixed carbides, shrinkage cavities, bubbles and other loose defects in the steel are extended and elongated along the processing method, and the cracks expand quickly. It is possible that only the external dimensions are guaranteed during forging. A streamline is formed, and this streamline has a great influence on the subsequent initial quenching deformation, cracking, embrittlement and failure tendency in the process of utilization. The cutting stress generated during final machining such as turning, milling, and planing can be eliminated by intermediate annealing. Hardened steel produces grinding stress during grinding, and produces resistance heat during grinding, resulting in a softened layer and decarburized layer, which reduces the thermal fatigue strength, and simply leads to hot cracks and early cracks. After precision grinding, h13 steel can be heated to 510-570°C, and the stress relief annealing can be completed with the thickness of 25mm for one hour. EDM produces stress. A bright white layer enriched with electrode elements and dielectric elements is formed on the surface of the mold, which is hard and brittle. This layer itself will have cracks and stress. High frequency should be used in EDM to minimize the white layer. The polishing method must be removed and tempered. The tempering is carried out at the third tempering temperature. As a result, the mold will be cracked and scrapped prematurely, and the heat treatment of the mold will be improper. In particular, only quenching and tempering is used without quenching. Dongguan hardware products are subjected to surface nitriding process, and surface cracks and cracks will appear after several thousand die castings. When steel is quenched, stress is generated. The result of superposition of thermal stress during cooling and structural stress during phase transformation. Quenching stress is the cause of deformation and cracking. The solid must be tempered to eliminate stress. So we should pay attention to the above problems. Dongguan Hardware Co., Ltd. updates different content every day.
