Service HotlineThe existing automobile fastener nut is a common nut. After the nut is matched with the bolt, during the tightening or disassembly process, there will be a phenomenon of sliding wire, and the safety factor is relatively low; It is difficult to guarantee, easy to rust, requires frequent inspection and replacement, and increases the cost of using the car, which can no longer meet the needs of the market.
Semi-round head churchill citychurchill citychurchill cityplastic screws have high-quality characteristics such as insulation, non-magnetic, corrosion resistance, beautiful appearance, and never rust, and modified engineering plastics, its strength and impact resistance are comparable to those of metals. The churchill citychurchill citychurchill cityplastic screws we often say are commonly known as nylon. After adding 30% glass fiber to the screw, its mechanical properties are far superior to ordinary nylon. The materials used for the dome head churchill citychurchill citychurchill cityplastic screws are becoming more and more diverse, the performance is constantly improving, and the application fields are becoming wider and wider. 1. Medical equipment industry (insulation, non-magnetic, environmental protection, anti-interference, make medical equipment safer to use) 2. Wind power industry (isolation and insulation of chassis circuit PCB boards) 3. Aerospace industry (electronic equipment Insulation, anti-interference) 4. Office equipment industry (never rust, beautiful and practical) 5. Petrochemical industry (high temperature resistance, chemical resistance, corrosion resistance, prolong equipment life) 6. Electronics industry (insulation, anti-interference) , light weight) 7. Communication industry (insulation, non-magnetic, safety) 8. Ship industry (acid resistance, alkali resistance, corrosion resistance, extended service life), etc... .
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 54 .
