Service Hotlineflat washer is a part that is placed between the connected part and the bolt to protect the surface of the connected part from being scratched by the nut and to disperse the pressure of the nut on the connected part. At present, a flat washer in the prior art generally includes a washer body; the washer body has a bolt hole in the middle for a bolt to pass through. Although the flat washer of the above structure has a simple structure, it still has a disadvantage. When the flat washer is cushioned between the connected part and the bolt, the bolt head is usually exposed outside the connection part, so the bolt head is easy to It is damaged under the impact of external force, thus affecting its fixing effect.
The advantages of the pressure riveting nut: 1. The length guarantee of the distance range is realized, which greatly simplifies the assembly process and speeds up the production progress of the assembled spacing panel and accessories; 2. The back of the plate is completely embedded and flat, while ensuring the head of the nut column The plane is smooth with the plate; 3. The raw material is free-cutting iron or free-cutting stainless steel; the technical guide for the application of the pressure riveting standoff: 1. When selecting the standoff, it must be based on the thickness of the plate used, the exact size range, and the hardness of the low-carbon steel plate must be less than 70RB, the hardness of stainless steel plate must be less than 80RB. 2. The surface of free-cutting iron is treated, and the stainless steel maintains its original color. Users can order according to the model and specifications in the table according to their needs, or they can also make special orders according to their needs. 3. The hole size of the plate must be processed according to the tolerance size of 0-+0.075mm, and punching is recommended. 4. The installation must be realized by press riveting operation, and it must not be knocked in by impact. 5. When the material is stainless steel, the tail number should be marked with S. 6. The end face of the nut column is represented by C. 7. The length of the through-hole nut column is full wire below 10mm. If it is above 10mm, it can be reamed on the hexagonal end face (type I) or the round end face (type II).
An embodiment of Guangdong Yueluo Hardware Industry Co., Ltd. provides a screw slotting device, as shown in Figure 1, which includes a workbench 1, a vibrating plate 2 is arranged on the upper part of the workbench 1, and a conveying device 3 is arranged on the vibrating plate 2. Below the discharge port, the slotting device 4 is arranged on one side of the conveying device 3, and the slotting device 4 is provided with a reciprocating cutting wheel 42 that can slot the screws in the conveying device 3 when it extends out. The device 4 is also fixedly provided with a fixed wheel 48 for grinding the grooved screws. Using the screw slotting device, the screws can be automatically sorted by the vibrating plate 2, which improves the production efficiency. The reciprocating motion of the cutting wheel 42 can greatly reduce the probability of knife breakage. Sanding, fixes burrs and roughness.
The beneficial effects of Guangdong Yueluo Hardware Industry Co., Ltd. are: the chip nut provided by Guangdong Yueluo Hardware Industry Co., Ltd. has a circle of serrated teeth protruding outward on the edge of the welding end face. During welding, excess solder After overflowing, it flows into the peripheral serrated convex tooth gap. In this way, on the one hand, the solder on the welding end face can be made uniform, and the welded chip nut can be neat and beautiful. On the other hand, the overflowed solder is combined with the serrated convex tooth gap. The welding area is increased, and the firmness and reliability of the welding are improved.
The earliest rivets were small pegs made of wood or bone, and the earliest metal variants may be the ancestors of what we know as rivets. They are without a doubt the oldest known method of joining metals, dating back as far as the earliest use of malleable metals, eg: Bronze Age Egyptians riveted the six wooden sectors of the outer lines of a slotted wheel with rivets Fastened together, after the Greeks had succeeded in casting large statues in bronze, the parts were riveted together with rivets.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: aluminum big brim blind rivets, inch hexagon screw caps, black one-piece decorative nuts, yellow embedded nuts and other products, we can provide you with The right fastener solution for you.
