Service HotlineIn order to solve the problem of nut loosening, various self-locking nuts have appeared, which have complex structure, high production cost, inconvenient installation and unsatisfactory anti-loosening effect. At present, the never-loosening nuts produced in Japan are mostly used, mainly in the form of double nuts. Each nut is provided with an eccentric cam protrusion, and each nut is provided with a groove and an inclined plane to squeeze the cam protrusion of each nut. When pressing, the cam protrusion of the nut will move to a small radius along the slope of the nut, so that the nut will not loosen, but whether it is a nut or a nut, it is always under the action of eccentric force. In addition, various non-loose nuts designed by many manufacturers are to increase the friction between the nut and the fastening workpiece or increase the barb to achieve the purpose of never loosening, but the effect is not ideal.
PortlandPortlandFlat washers are frequently used in mechanical connections. They are usually placed between the nut or screw head and the connected parts to prevent the screw or nut from loosening during use. The upper and lower end faces of conventional flat gaskets are mostly smooth planes, with a single structure and poor compressive capacity. When assembled with a nut or screw, the pressure on the flat washer is increased, and when it is closely rubbed with the nut or screw, it is prone to breakage, which greatly affects the quality of the product.
PortlandStainless steel screw wire is also called stainless steel cold pier wire, which is mainly used for various fasteners, such as mechanical parts, electronic application parts, etc. Corresponding anti-corrosion properties and mechanical properties can be obtained according to different materials. In order to obtain a better formability during cold forging, choose high quality. The appropriate material of the wire is particularly important.
The automatic screw-removing device includes a manipulator and a screw-removing mechanism arranged on the manipulator, and the electric batch can drive the bit to rotate to remove the screws. Therefore, the above-mentioned automatic screw removal device can automatically remove the screws, which improves the removal efficiency and reduces the production cost. At the same time, the above-mentioned automatic screw removal device determines the coordinates of the screw through the visual recognition unit, which improves the degree of screw positioning, thereby improving the yield of the screw removal. The above-mentioned screw removal method can realize the automatic removal of the screw, and adsorb the screw through the bit head and drive the screw away from the workpiece.
Bolts refer specifically to screws with larger diameters and may also have no heads, such as Portlandstud bolts. In general, it is not called a stud bolt but a stud stud. The most common form of stud is threaded at both ends and a polished rod in the middle. The most typical use: anchor bolts, or places similar to anchor bolts, thicker connections, when ordinary bolts cannot be used.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: medium carbon thin nuts, reversed nuts, iron Portlandself-locking lock nuts, round wing butterfly type ingot nuts and other products, we can provide You have the right fastener solution for you.
