Service HotlineT-bolts are often used in conjunction with flange nuts, which are standard supporting connectors when installing corner fittings, and can be automatically positioned and locked during the installation process. At present, in the welding process of T-bolts, there is often a method of manual welding. Using such a method, the manufacturing cycle is long, the labor intensity is high, the production efficiency is low, and the welding quality is difficult to guarantee.
Drilling screw is a new invention of people in recent years. A screw is a common term for fasteners, an everyday colloquial language. The tail of the drill tail screw is in the shape of a drill tail or a pointed tail, and no auxiliary processing is required. Drilling, tapping and locking can be directly carried out on the setting material and basic material, which greatly saves construction time. Compared with ordinary screws, its toughness and pull-out force and maintenance force are high, and it will not loosen for a long time after combination. It is easy to use safe drilling and tapping in one operation. Drill tail screw Drill tail screw use: It is a kind of screw, mainly used in the fixing of color steel tiles of steel structures, and can also be used for thin plate fixing of simple buildings. It cannot be used for metal-to-metal bonding. Materials and models The materials are iron and stainless steel, of which stainless steel is divided into various materials. Models are: Φ4.2/ Φ4.8/ Φ5.5/ Φ6.3mm, the specific length can be agreed upon request. According to the different drill tails, it can be divided into: round head rice / cross / plum blossom, countersunk head (flat head) / rice seed / cross / plum blossom, hexagonal washer, round head washer (big flat head), horn head, etc.
The advantage of wood screws is that the consolidation ability is stronger than that of nails, and they can be removed and replaced, which is more convenient to use without damaging the wood surface. This is a kind of nail specially designed for wood, and after entering the wood, it will be embedded in it very firmly. If the wood is not damaged, it is impossible to pull it out, and even if it is pulled out forcibly, it will bring out the nearby wood. Another point to note is that the wood screws must be screwed in with a screwdriver. Never knock them in with a hammer, as it will damage the surrounding wood. A screwdriver is a tool for loading and unloading wood screws. The shape matches the groove shape of the wood screw head, and there are two types: one-word and cross-shaped. In addition, there is a special screwdriver installed on the bow drill, which is suitable for loading and unloading large wood screws. Convenient and labor-saving. [2]
The traditional gasket is a single-piece gasket that works independently. This gasket mainly relies on friction to achieve the anti-loosening effect. The new washer is composed of two pieces. Its unique embedded structure changes the way that the traditional washer mainly achieves anti-loosening through friction. Instead, it adopts the most advanced anti-loosening technology in the world and uses the tension between the two gaskets to achieve. The dual effect of anti-loosening and tightening.
The height of the existing assembly devices is fixed, and the height of the workers is different, so it is very inconvenient to use, resulting in a decrease in efficiency. With the progress of science and technology and the development of society, people have proposed higher assembly devices. Therefore, we propose a shaft card assembly device to solve the above problems.
