Screws are a kind of fasteners commonly used in daily life and industry. At present, in use, different types of screws are generally selected for fixing according to different screw lengths and other parameters. Since the screw length is fixed at the time of manufacture, when When using a large number of screws with different screw lengths, it is necessary to sort out screws with different screw lengths beforehand. This method is more troublesome, and sometimes in some special occasions, some screws with special lengths are required. Producing screws of this particular length individually is laborious and laborious.

In order to solve the above technical problems, Yueluo provides a screw installation method. When using this method to install screws, the sensor must sense that the screws have been adjusted to the specified position before allowing the screws to be energized, which prevents the screws from being adjusted. Accidents of personal injury caused by operating errors during the process. The technical solution adopted by Yueluo to solve its technical problems is a screw installation method, which includes the following steps: a. Fix the screw hole structure that needs to be installed on the workbench, and fix the corresponding size screw to the screw mouth; b. Adjust the sensor on the track groove to the vertical position just above the screw hole structure; c. Adjust the screw position until the sensor on the screw senses the signal sent by the sensor; d. Turn on the screw power supply, and install the screw into the screw Inside the hole structure, the installation is complete. Compared with the prior art, Yueluo has the following beneficial effects. The screw installation method provided by Yueluo has the steps of preventing accidental hitting, which avoids personal injury accidents caused by operation errors during the screw adjustment process.

Riveting is the most traditional way of connecting metal parts. It has the advantages of easy operation, high reliability and not easy to deform. It is widely used in the skeleton of outdoor products such as tents and camp beds. Commonly used aluminum alloy rivets use their own deformation or interference to connect the parts of the riveted parts in the riveting process. Due to cost and functional considerations, the rivet and the riveted material are often different, which is easy to occur in outdoor high humidity. Electrochemical corrosion, and the commonly used high-strength thin-walled pipes have a large shear stress on the aluminum alloy rivets at the riveting point. Under the combined action of the above two factors, it is easy to cause deformation or even breakage at the riveting point, which affects the life of outdoor products. A kind of Corrosion and shear resistant aluminium alloy rivets.

Friction type high-strength bolts: suitable for beam and column connections of steel frame structures, solid web beam connections, heavy-duty crane beam connections in industrial plants, braking systems and important structures bearing dynamic loads. Pressure-bearing high-strength bolts: Can be used for shear connections in statically loaded structures that allow a small amount of sliding or in members that are indirectly loaded with dynamic loads. Tensile high-strength bolts: When the bolts are in tension, the fatigue strength is low. Under the action of dynamic load, its bearing capacity is not easy to exceed 0.6P (P is the allowable axial force of the bolt). Therefore, it is only suitable for use under static load. Such as flange butt joints, T-joints, etc. of pressure members.

1. The twisted screw should be considered according to the actual inner diameter of the barrel, and the outer diameter deviation of the new screw should be given according to the normal clearance with the barrel. 2. After the thread surface with the reduced diameter of the worn screw is treated, the wear-resistant tungsten carbide alloy is thermally sprayed, and then ground to size. 3. Surfacing wear-resistant tungsten carbide alloy on the thread part of the worn screw. According to the degree of screw wear, surfacing welding is 1~2mm thick, and then the screw is ground and processed to size. This wear-resistant tungsten carbide alloy is composed of materials such as C, Cr, Vi, Co, W and B, which increases the wear resistance and corrosion resistance of the screw. 4. The bottom diameter of the screw is repaired by electroplating hard chromium. Chromium is also a wear-resistant and corrosion-resistant metal, but the hard chromium layer is easier to fall off.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: GB873 hollow core aluminum blind rivets, circular decorative hollow washers, extended screw pads, 1.5 teeth screws and other products, we can help you Provide the right fastener solution for you.
