Service HotlineHowever, this process scheme has high cost, low efficiency, and has certain difficulties in quality assurance. In order to ensure product production efficiency, reduce manufacturing costs and improve product quality, it must be considered that the blank forming is completed on a multi-station cold heading machine at one time.
In order to solve the problem of poor waterproof performance of the existing rivets, Guangdong Yueluo Hardware Industry Co., Ltd. provides a waterproof rivet. By arranging a figure-eight waterproof part for waterproofing on the lower end surface of the waterproof cap, when the object is riveted, The waterproof cap is subjected to the pulling force of the rivet rod and the supporting force of the object. The pulling force and the supporting force cause the waterproof cap to generate stress, which in turn causes the waterproof part of the waterproof cap to be micro-deformed in the closest contact with the object, so as to achieve a good sealing effect.
The technical solution adopted by Yueluo to solve its technical problems is: a cabinet with a hidden screw type installation structure. The cabinet includes corner fittings, frame profiles and plates. Connecting slot, the plate installation slot is U shaped, the plate installation slot on the frame profile can be set with one or two, the insertion slot is located on the inner side of the plate installation slot; the main body of the corner fitting is fixed in three directions. The plug connector, the outer side of the plug connector is provided with auxiliary plate installation grooves, and the auxiliary plate installation groove is provided with side baffles; the plug connectors on the corner fittings are correspondingly inserted into the plug connectors on the frame profile, and the cross section of the plug connector Consistent with the cross-sectional size of the corresponding insertion slot, the plate is inserted between the plate installation slots on the frame profile.
Therefore, in order to obtain fasteners that meet the requirements, it is usually necessary to anneal the middle sections of bolts, rivets, etc. to reduce the hardness of the middle sections, while ensuring the hardness of the heads of bolts, rivets, etc. At present, the existing process adopts ultra-high frequency induction heating equipment to instantly heat the middle section and reduce the hardness. However, this process requires a lot of control, and the heating time is slightly longer, which affects the hardness of the head, and the mass production is very unstable, which is easy to cause the rivet to fail. At the same time, the cost of ultra-high frequency equipment is high and the power consumption is large, which is not conducive to mass production and energy saving. Environmental friendly.
rivet is a metal rod-shaped part with a cap at one end. During riveting, the rivet uses its own deformation or interference to connect the riveted parts. Commonly used rivets are semi-circular head, flat head, semi-hollow rivets, solid rivets, countersunk head rivets, Tipperaryblind rivets, hollow rivets, etc. At present, rivets are widely used in various backplane products and other stamping products. Since rivets are responsible for the functions of locking, positioning and bearing lateral force in the product, the degree of riveting and vertical have higher requirements. However, in actual production, there are often problems such as the failure of the rivet torsion to meet the requirements, the rivet being skewed by the rivet, the surface of the rivet being cut, the rivet placement being inaccurate and requiring manual repositioning, etc. Very high and very inefficient.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: French standard washers, screw nuts, outer and inner serrated Tipperarystop washers, A-type square spot welding nuts and other products, we can provide you with suitable products for you.
