The use of the screw is mostly used in plastic molding equipment, such as plastic profile extruders, injection molding machines, etc. Screw and barrel are the core components of plastic molding equipment. It is the part of heating extrusion plasticizing. It is the core of plastic machinery. Screws are widely used in machining centers, CNC machines, CNC lathes, injection molding machines, wire cutting machines, grinding machines, milling machines, slow wire walking, fast wire walking, PCB drilling machines, engraving machines, engraving and milling machines, spark discharge machines, tooth bite machines , planer, large vertical lathe gantry milling, etc.
Fasteners such as bolts and rivets are called the rice of industry, and they are used in infrastructure construction, equipment machinery, automobile manufacturing, electronic information, aerospace and other industries. According to the mechanical properties of fasteners, fasteners are divided into high-strength fasteners and ordinary fasteners. At the end of the 20th century and the beginning of the 21st century, with the rapid development of the economy, the demand for anti-seismic and anti-loose fasteners surged. Although the fasteners are small, their quality and reliability play an important role in the performance and structural safety of the main engine. Incredible.
The hinge is a hinge, which is often composed of two folds. It is a part that connects the two parts of the object and can make it move. The hinge supporting screws are installed on the corresponding objects. For different use environments, the requirements for the supporting screws are also different. different. Most of the existing screws are set to a single-threaded structure. When used to cut into a wooden door, the cutting speed is slow, and the cutting effect is not ideal, which is not conducive to cutting into a hard wooden door, etc., and the commonly used screws are often made of iron materials. It is easy to rust after contact with water vapor, reducing the service life; in addition, when the screw is driven into the wooden door, the chips generated cannot be discharged in time, and stay inside the wooden door and surround the screw, forming expansion stress, thereby squeezing the wooden substrate, which is not conducive to the screw. The connection with the wooden door is stable, which easily affects the normal installation of the hinge, and the use effect is poor. To sum up, in order to solve the shortcomings of the existing screw structure for hinges, Guangdong Yueluo Hardware Industry Co., Ltd. designed a hinge screw with simple structure, convenient use, fast construction and good effect.
With the mass production of large-scale equipment, standardization, and the concept of lean production, it has become more and more important to improve the efficiency of the assembly stage. Nowadays, when assembling small equipment, power tools and automatic bolt supply devices are basically popular, but only for M3 and smaller However, large equipment is often fastened with M8 or larger diameter bolts, and it is still in the process of combining manual and air tools. Among them, the pre-installation of the flat and spring washers on the bolts is completely manual operation. When the bolts need to be tightened in large quantities, the shortcomings of low efficiency are particularly obvious, and the flat and spring washers are easy to be scattered when manually assembled, and there are mixed installations of different specifications. Problems such as less installation and missing installation will affect the processing quality.
