Service HotlineThe production process of rivet nuts is basically similar to that of other screws. It's just that the screws are punched out with a screw pier, and the nuts are punched out with a nut pier. Introduce the production process of rivet nuts. 1. First, it is necessary to determine what material and material the rivet nut is, so that we can use what material to produce and what material to use. Knowing what materials and materials are used, we can buy screw wires. 2. Determine the size and length of the rivet nut. This is the best way to use a large screw wire. 3. After determining the material, material, size and type, we need to see if it is a commonly used rivet nut. If so, there must be a corresponding mold in the factory. If not, it is non-standard, then we have to order molds. 4. After everything is ready for production, it is necessary to use the nut machine to punch out the shape of the rivet nut, that is, the appearance. 5. After the pier is punched out, use the machine for tapping the nut teeth to tap it. 6. After the thread is tapped, electroplating is performed. The stainless steel rivet nut does not need electroplating, it only needs to be cleaned. If you want to electroplate other colors, you have to take it to a professional electroplating manufacturer for electroplating treatment.
Hexagon head bolts are divided into two types: outer hexagon bolts and inner hexagon screws. According to the force mode of the connection, there are ordinary ones and those with reaming holes. The bolts used for reaming holes should be matched with the size of the holes and are used when receiving lateral force. According to the shape of the head, there are hexagonal head and round head. , square head, countersunk head, etc. Generally, the countersunk head is used in places where the surface is smooth and no protrusions are required after connection, because the countersunk head can be screwed into the part. The round head can also be screwed into the part. The tightening force of the square head can be Larger, but larger in size. Hexagons are the most commonly used. In addition, in order to meet the needs of locking after installation, there are holes in the head and holes in the rod. These holes can prevent the bolts from loosening when they are subjected to vibration.
Yueluo - a screw and nut disassembly tool for a narrow space, including a sleeve rod, a sleeve rod vertically arranged at one end of the sleeve rod, a connecting rod for fixedly connecting the sleeve rod and the sleeve rod, and a sleeve rod located at the end of the sleeve rod. The connecting rod in the axial through hole of the sleeve rod, the connecting rod located in the axial through hole of the sleeve rod, and the bearing for fixedly connecting the sleeve rod and the connecting rod and making the connecting rod rotate stably in the sleeve rod , and a sleeve head arranged at one end of the connecting rod, the connecting rod and the adjacent end of the connecting rod are provided with gears and the two gears are vertically meshed, so that when the external force drives the connecting rod to rotate, the force passes through The two gears and the connecting rod are transmitted to the sleeve head, thereby driving the screw or nut in the sleeve head to rotate;
The materials of rubber gaskets are usually NBR (nitrile butadiene rubber), SBR (styrene butadiene rubber), HNBR (hydrogenated nitrile butadiene rubber), EPDM (EPDM rubber), SILICONE (silica gel), VITON (fluorine rubber), CR ( Neoprene), FFKM (perfluoroelastomer), etc.
The existing spring pads are generally composed of longitudinal support springs, transverse connection springs, support springs, frames and frame clips. (Commonly known as string spring) is a slender and constant warp spring, used to connect the longitudinal support spring. The support spring is located at the edge of the spring pad to increase the shear resistance of the spring pad and the support strength of the frame. The surrounding frame connects the spring to the spring. up, fixed. The existing treatment method is to first heat-process the longitudinal support spring and the support spring made of 70# steel wire through the winding spring in a chemical solution, arrange them, and fix and connect them with a string spring, a frame and a clamping piece. Because the string spring and the frame have not been chemically heat treated, there is a large internal stress. Therefore, this treatment method has two disadvantages. One is that the processing efficiency of the heat treatment support spring is low. Larger, the spring is easily deformed and the service life is affected. In addition, the chemical solution after heat treatment is easy to cause environmental pollution
