Service HotlineIn industrial production, some products need to remove the fixing screws; or in the assembly line, the screws that fix the product on the fixture also need to be removed when the product is unloaded. At present, the dismantling of the screws is mainly completed by the manual operation of the operator. However, this method of manually dismantling the screws has low work efficiency and high production cost.
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.
Although there are many types of self-tapping locking screws, they all have the following main characteristics: (1) Generally, they are made of carburized steel (accounting for 99% of the total products). Also available in stainless steel or non-ferrous metals. (2) The product must be heat treated. Carbon steel self-tapping screws must be carburized, and stainless steel self-tapping screws must be solution hardened. In order to make the self-tapping screw meet the mechanical properties and performance required by the standard. (3) The product has high surface hardness and good core toughness. That is, inner softness and outer rigidity. This is a major feature of the performance requirements of self-tapping screws. If the surface hardness is low, it cannot be screwed into the matrix; if the toughness of the core is poor, it will break as soon as it is screwed, and it cannot be used. Therefore, inner softness and outer rigidity are the requirements for self-tapping screws to meet the performance requirements. (4) The surface of the product needs surface protection treatment, generally electroplating treatment. Some product surfaces require phosphate treatment (phosphating). Such as: wall panel self-tapping screws are mostly phosphating. (5) It is produced by cold heading process. It is recommended to use high-speed cold heading machine and high-speed thread rolling machine or high-speed planetary thread rolling machine to ensure product quality. The self-tapping screw produced in this way has a well formed head and high thread quality.
In another embodiment of Guangdong Yueluo Hardware Industrial Co., Ltd., the conveying device 3 includes a motor 31 and a circular rotating disk 34, the motor 31 drives the circular rotating disk 34 to rotate, and the circular rotating disk 34 is evenly provided with screws in the circumferential direction. The matching screw accommodating hole 35, the screw enters the screw accommodating hole 35, the motor 31 drives the circular rotating plate 34 to rotate, so that the screw is first slotted by the cutting wheel 42, and then polished by the fixing wheel 48, and the screw is in the screw accommodating hole 35. It is fixed, which is more secure and reliable during the slotting process. Preferably, the circular rotating disk 34 includes a circular rotating disk 32 and a sector-shaped fixed disk 33. The circular rotating disk 32 is evenly provided with screw receiving recesses matching the screws in the circumferential direction, and the recesses and the sector-shaped fixed disk 33 are formed with the screws The matching screw receiving holes face the cutting wheel 42 and the fixing wheel 51 .
The global economy continues to slump and overseas export trade is sluggish. Many fastener companies at home and abroad are facing severe tests. Accelerating economic transformation and structural upgrading is imminent, and developing overseas markets is undoubtedly an important way out for the development of the current fastener industry. From the fourth quarter of 2011 to the first half of 2012, affected by the objective environment, the development speed of the fastener industry may slow down, but from the third quarter of 2012, with the policy in place, the convening of the 18th National Congress of The upcoming series of development policies, etc., can promote the further development of the industry. And we must insist on innovation and adjustment and transformation, we must continue to rely closely on key industries such as automobiles, new energy, aerospace, shipbuilding, urban transportation, IT, electronic appliances, construction, etc., accelerate the optimization and upgrading of fastener products, and promote fasteners. The whole industry develops healthily and steadily. The global fastener market size exceeds 50 billion US dollars, and China's total fastener production in 2012 is also expected to reach about 6.8 million tons. However, compared with the manufacturing powerhouses such as the United States and Japan, there is still a big gap in my country's fastener industry.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: yuan nuts, polished and hardened, UNI8737, round head torx bolts and other products, we can provide you with suitable fastener solutions for you.
