Wardrobe sliding door hardware accessories knowledge introduction
[ Chinese wardrobe net ] The charm of sliding door is sliding, the quality of sliding door hardware accessories directly affects the service life and quietness of sliding doors. Sliding door hardware mainly includes pulleys, pulley tracks and stop gadgets. The high-quality mobile door hardware is mainly reflected in the design and manufacturing level of its pulley system and the matching track design.
Three main departments of sliding doors: borders, pulleys, tracks
1. Frame material. At present, the frame materials of sliding doors on the market mainly include: carbon steel, aluminum alloy, aluminum-magnesium alloy, titanium magnesium alloy and the like. Among them, carbon steel has the lowest price and titanium magnesium alloy has the highest price.
The thickness of the frame profile is generally 1.2mm - 1.5mm, so that the sliding door can be up to 2.8 meters, and it will not be twisted and is relatively stable. If the wall thickness is less than 1.2mm, if some are only 0.8mm or 1.0mm, the maximum can only be 2 meters. If it is too high, it will be tweaked and it is easy to raise the problem. The thickness determines the price of the profile, and the cost is relatively high, which also determines the firm function of the sliding door.
The composition of the profile is roughly divided into two types: one is aluminum alloy and the other is plastic steel (carbon steel). Because aluminum alloy has the characteristics of light weight and high strength, it is the main material of sliding door substrate, and has gradually replaced plastic steel products. The aluminum alloy itself is divided into ordinary aluminum-magnesium alloy and aluminum-magnesium titanium-silicon alloy. Aluminum-magnesium-titanium-silicon alloy is a special material for aviation industry. It has higher strength and smaller weight. It has the advantages of oxidation resistance and erosion resistance. It is favored by consumers, but its cost is several times that of ordinary aluminum-magnesium alloy.
2. Pulley. The most important part of the sliding door is the pulley that carries the weight of the whole door. It is necessary to pay attention to the selection of high-quality high-strength wear-resistant nylon bushings, and the nylon surface must be very smooth and cannot have prismatic protrusion; the inner ball bracket is also high-strength nylon structure. The friction is reduced and the lubrication function of the bearing is enhanced; the bearing structure of the bearing is steel structure, the design can effectively reduce the noise during the sliding process of the pulley, and can make the pulley need no care, enjoy the light lubrication for at least ten years .
A roller is roughly divided into two parts, one is a bearing and the other is a bearing outer layer. The quality of the bearing plays a pivotal role in the durability of the sliding door. For example, Huitailong sliding door hanging wheel bearing adopts needle roller bearing, which can maintain precise guiding, high load and smoother, and adapt to the ambient temperature between -20 °C and 120 °C.
The twin pulleys have the function of wear resistance and noise reduction. There are two pulleys sliding in parallel to further ensure the quietness, smoothness and chaos of the push and pull. In addition, good pulleys are often designed with two anti-jump devices to ensure reliable and safe sliding of the doors. Poor pulleys often have only one anti-jump device, and even no anti-jump device. It is easy to derail when in use, and it is difficult to ensure safety.
3. Tracks. The pulley guide is the core technical part of the sliding door. It must withstand repeated friction, so the guide rail must have high strength and wear resistance. The track associated with the pulley is also critical to the use of the sliding door. The track for sliding doors generally has two types of cold rolled steel rails and aluminum alloy rails.
Consumers generally think that the rails are more durable than the aluminum alloy rails. The thicker the rails, the better. It is not entirely true. High-quality sliding door hardware is the perfect combination of track and pulley, not just a single part. The track must have a perfect curvature with the pulley, followed by the material.
