Service HotlineAt present, in the process of injection molding, stamping, testing, etc., the product is usually positioned on the mounting plate or the positioning plate by pins. The general pin positioning method uses cylindrical pins with the same cross-sectional diameter for positioning. Because the product is easily deformed during processing, the pin positioning hole on the product is also deformed. With this kind of pin for positioning, the pin is often stuck. Dead products cause inconvenience in handling the workpiece, resulting in broken pins or scratched or even damaged products, with obvious defects.
The grooved embedded parts are usually connected by bolts, and there are many types of T-bolts used with the grooved embedded parts. position, so that the T-bolt can form a stable connection with the groove-type embedded part, but in the actual installation process, the T-bolt pressed into the groove-type embedded part is prone to loosening problems, so it is difficult to better Fixed in trough embedded parts.
The application range of the oil pump is very wide. When it is used, the oil pump needs to be assembled. During the assembly process, when the pin is driven into the pin hole, it is generally held by the operator with a hammer, and then aiming at the top of the pin to press. Into the hole, due to the relatively high tolerance requirements for the depth of the pin pressing and the side clearance (the gap between the pin and the groove wall), the traditional operation method not only causes a high rejection rate and a long training time for personnel, but also The slow processing speed affects the production efficiency.

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.
