Service HotlineFlat washers are usually thin pieces of various shapes used to reduce friction, prevent leakage, isolate, prevent loosening, or distribute pressure. Such components are found in many materials and structures to perform a variety of similar functions. Restricted by the material and process of threaded fasteners, the bearing surface of fasteners such as bolts is not large, so in order to reduce the compressive stress of the bearing surface and protect the surface of the connected parts, washers are used.
Dowels are made on the steering seat on the ball head of the car, and the rollers are assembled to the steering seat through the dowels. The prior art is manual driving of the pins, and the position of the pins is inaccurate when driving the pins, the labor intensity is high, the efficiency is low, and the quality of the steering seat is also affected. Therefore, it is necessary to design an automatic pin-driving mechanism to drive the pins into the steering seat. .
For common screw belts, please refer to the Central Taiwan Announcement No. 327442 Screw Belts (2) on February 21, 1998. It includes a main body, and there are multiple grooves on the side of the main body, which are used for locking screw tools to drive the belt. A toggler; and a plurality of nail grooves are arranged on the nail belt so that the screw planting is arranged in an arrangement, and the nail grooves are all provided with through holes, and the through holes extend downward with a ring to form a support portion for the screws; and the It is surrounded and provided with a plurality of cutting grooves, which is beneficial for the screw to be rotated through the nail groove; and it is characterized in that the nail groove is located on the inner wall surface of the surrounding and is provided with a plurality of lobes, and these lobes are implanted in the screw. In the nail groove, the leaflet supports the screw, so that the screws with different outer diameters are fully supported and positioned by the leaflet; and/or the upper part of the leaflet is inclined or curved, so that a depression is formed above the ring to support the screw The arc surface or tapered surface of the neck can make the screw more stable to be supported.
In the modern industrial field, products such as nuts and bolts are widely used to lock structural parts, but at the same time we also find that in many cases, especially when applied to vibration, we often need to lock the already locked Structural parts are regularly repaired and strengthened to prevent structural dislocation caused by loose nuts and bolts.
In some special occasions, both objects need to be riveted and have good waterproof performance. The existing rivets have poor waterproof performance and often have problems such as water seepage.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: lifting ring joint bolts, brass knurled screws, national standard nuts, JB4364 screws and other products, we can provide you with suitable fastener solutions for you Program.
