Service HotlineFasteners are a general term for a type of mechanical parts used to fasten two or more parts (or components) to form a whole. Among them, self-fastening fasteners are widely used in the connection of sheet metal parts due to their advantages of fast installation, high efficiency, reliability, convenient assembly, high push, pull and torsion performance, wide range of applicable materials and serialization of specifications. middle. Nuts are the most widely used type of fasteners. With the continuous change and development of the scope of use and the use environment, more demands are put forward for nuts. In particular, some occasions require the nut to have the function of waterproof sealing. The existing methods of nut sealing and waterproofing generally have the following types:
The grooved embedded parts are pre-embedded in concrete, and then placed in the groove with T-bolts. After adjusting the fixed position, the fixed object is locked with a nut to achieve the fixing effect. When the grooved embedded parts are embedded vertically in the concrete or at a certain angle to the horizontal line, the T-bolts are likely to move in position before they are tightened. In particular, when fixing heavy equipment, multiple T-bolts are required, and multiple groups of workers are required to help and positioning is difficult, and the installation process is complicated.
Guangdong Yueluo Hardware Industry Co., Ltd. has a simple structure, low processing difficulty, and convenient riveting. The whole pin has the same diameter except for the annular groove. The drawn wire can be directly used, which saves the cost of materials and machining costs, and improves the production speed and efficiency. The structure does not require high machining accuracy of the hole, which can effectively reduce the machining cost and the rework rate of the parts.
The traditional single-sided riveting process mainly adopts two methods: rivet nut connection and blind rivet connection. The efficiency of the rivet nut is low. If the hollow nut is used, the rigidity is insufficient, resulting in low connection strength. In addition, the torsion resistance of the rivet nut is low. If the rivet nut is used to obtain better torsion resistance, it is made into a hexagonal shape. Embedding, because the shape of the sheet metal opening also needs to be made into a corresponding hexagon, it is inconvenient to process.
screw grooving device comprises a workbench, a vibrating plate is arranged on the upper part of the workbench, a conveying device is arranged below a discharge port of the vibrating disc, the slotting device is arranged on one side of the conveying device, and the slotting device is provided with a reciprocating device. When the movement is extended, the cutting wheel can be used for grooving the screws in the conveying device, and the grooving device is also fixedly provided with a fixed wheel for grinding the grooved screws.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: nut bolts, die washers, hexagon nut bolts, closed flat round head rivets and other products, we can provide you with suitable fasteners for you solution.
