Nuts are parts that tightly connect mechanical equipment. Through the inner threads, nuts and bolts of the same specification can be connected together. For example, M4-P0.7 nuts can only be connected with M4-P0.7 series bolts (in the nut). Among them, M4 means the inner diameter of the nut is about 4mm, and 0.7 means that the distance between the two threads is 0.7mm); the same is true for American products, for example, a 1/4-20 nut can only be matched with a 1/4-20 screw ( A 1/4 finger nut has an inner diameter of about 0.25 inches, and 20 fingers have 20 teeth in each inch).
As shown in FIG. 1 and FIG. 2 , a rivet die in the prior art includes a set of top die 1 and cover die 2 arranged opposite to each other. The top die 1 is provided with a cavity 1 in the center that matches the shape of the rivet dome head 3-1. -1, the center of the cover mold 2 is provided with a mold cavity 2-1 that matches the shape of the rivet dome head 3-3.
Gaskets are widely used in the machinery industry. According to the different needs of machinery and equipment in different industries, the structural forms of the sealing points are also different. Plum washer is one of the commonly used seals. It is commonly used between the pump and the motor coupling. In the actual production process of the enterprise, it is found that due to the influence of the material and structure, this type of gasket in common use can withstand impact force. Small, the septum is easily damaged. Because the current plum washers are all one-piece structures, even if one or several of the partitions are damaged, they need to be replaced as a whole. Although the value of a single plum washer is low, it needs to be shut down for maintenance and replacement almost every week. It also seriously affects the normal production of the enterprise, and the one-piece plum blossom gasket is also difficult to repair, adding unnecessary use costs to the enterprise. For this reason, the plum blossom gasket needs to be improved to strengthen the impact resistance of the gasket, and can be repeated Maintenance and use, prolong the maintenance cycle of the equipment, and ensure the normal production of the enterprise. The purpose of the utility model Yueluo is to solve the above-mentioned deficiencies in the existing technology, improve the existing technology, and provide a simple structure, which strengthens the impact resistance of the gasket, and can be repeatedly maintained and used to prolong the maintenance of the equipment. The cycle guarantees the plum blossom elastic washer normally produced by the enterprise. In order to achieve the above purpose, Yueluo is achieved through the following technical solutions-namely a plum blossom elastic washer, including an elastic washer body with a partition, the technical point is that the washer body is composed of a washer base and a partition that is independent of each other. , the septum and the gasket base are fixedly connected into one through the fixing piece. In order to further strengthen the impact resistance of Yueluo, the contact parts of the spacer and the washer base are respectively processed with a limited clamping table and a matching groove, so that the spacer and the washer base can be better integrated into one. According to the different specifications of the torx washer, the spacer and the washer can be fixed as a whole by rivets; or by screws. In addition, a semi-rigid tightening ring with grooves is embedded inside the washer base, and the width of the tightening ring is smaller than the width of the washer base; the ends of the rivets or screws are located in the grooves of the tightening ring, so as not to affect the performance of the torx washer JH is often installed. After the above improvement, Yueluo has improved the one-piece structure of the plum-blossom washer into a split structure and adopted a variety of fixed structure forms, so it has a simple structure, strengthens the impact resistance of the gasket, and can be repeatedly maintained and used. , Extend the maintenance cycle of the equipment and ensure the advantages of the normal production of the enterprise.
Guangdong Yueluo Hardware Industry Co., Ltd. provides a nut provided by Yueluo, which includes an internal thread. is an arc curve. Compared with the nut of the same type, the normal pressure and friction force of the nut are increased, the thread is not easy to loosen, and the bolt and nut are in surface contact, so it is not easy to cause stress concentration and local material yield, which effectively improves the tightening force of the bolt and nut. Stability, increase fastening reliability.
The function of the waterproof gasket is mainly to prevent the leakage of liquid or gaseous substances and the intrusion of external liquids, and has achieved the effect of sealing. Generally, the waterproof gasket is simply designed in the shape of a rubber ring plate.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: 4304 stainless steel screws, stainless steel nuts, ANSI screws, GB blackened washers and other products, we can provide you with suitable fastener solutions for you.
