Steel row nail is a T-shaped object made of 45# low carbon steel. One end has a flat head and the other end is sharp. The diameter of the nail rod is 2.2 ￠ and is glued together by glue. It is mainly used for decoration, fixation and connection. It can also be used to hang articles. Use st64 pneumatic gun instead of steel nail and hit it with a hammer.
Steel row nails adopt a series of production processes to effectively integrate the regularly arranged nail monomers, and integrate them through special adhesive to form a whole block of regularly arranged and fixed row nails.
The carbon content of steel nail is 0.4-2.8%, which is higher than that of steel nail.
There are 8 types of steel row nails, namely st-18 ST-25。  ST-32。  ST-38。 ST-45。  ST-50。 ST-57。  ST-64。
Interior decoration, wooden packing box, etc.
Analysis of automatic production process of steel row nails after research and analysis, the key technology of automatic production of steel row nails lies in how to realize the regular arrangement of nails, that is, all steel nails must be neatly arranged in a row, and the nail head is close to the nail head, the nail tip is close to the nail tip, and the nails are in close contact with each other. The design of this mechanism is directly related to the production efficiency of the machine. The reason why the previous machines could not be put into mass production was that the production efficiency was too low.
According to the production process of steel row nails, steel row nails cannot be produced automatically by the production process of paper, plastic and straight row nails. If the production process of ordinary row nails is adopted, the raw materials (steel wires) must be heat treated (quenched) and chrome plated first, and then these steel wires are made into wire strips. However, after heat treatment, the strength and hardness of the steel wire are greatly improved, which is bound to cause difficulties in nail making, and the hardness of the die is very high. At the same time, the previously plated chromium will also fall off in violent vibration.
In the research field of automatic production of steel row nails, the production process of steel row nails has gradually reached a consensus. The technological process mainly includes the following parts: separation, orientation, arrangement, gluing, drying, cutting, etc.
In the production process of steel row nails, separation, gluing, drying and cutting are easy to realize in the project. For example, the separation process can be completed by using the more commonly used electromagnetic vibrator. This technology has been very mature, and there are many kinds of equipment on the market. What is difficult to achieve is automatic orientation and arrangement, because the steel nails used in the steel row nails are T-shaped and very round, which is special and difficult to implement by conventional methods.
In actual use, if the steel nails are forced into the wall, the steel nails may be bent and broken, while the st steel row nails can be nailed in. The common drill bit used in decoration is omitted, and it is easier to nail into the steel row nail (steel nail) after nailing into the wooden wedge after drilling a hole in the wall. The air pressure of the air pump should be 0.4 ~ 0.8MPa. The fixed object should be fixed with the nail degree 1.5cm-2.5cm longer than the hanging object, which is firm and not easy to damage the wall.
