Summary of information:We have more than ten years of production experience in the screw industry. The main products are: GB62.1 wing nut, trip...

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.

Generally, we have to divide the fine thread nut and the coarse thread nut first, but in fact, no matter what kind of fine thread, coarse thread, their specifications are the same, their specifications are M3, M4, M5, M6, M8, M10, etc. . But there is another kind of hexagonal nut, which is divided into English and American, which is only a different national standard. Made in China, it is called the national standard hexagon nut

Fastening of such functional elements in flat gaskets is usually achieved by additional measures or by a special design of an additional, functional layer adjacent to the carrier layer, or by a special design of the parts to be sealed. Fastening the functional elements in this way is laborious and expensive, and is only possible for special gasket designs.

hand screw is a screw with a plastic head, and the user fixes the hand screw by turning the plastic head by hand. At present, a hand-tight screw is disclosed in the market publication number CN202203253U, which includes a plastic head and a screw rod, the plastic head and the screw rod are connected together, and the height of the plastic head is higher than that of ordinary screws, and the height is 9cm. The screw of the hand screw is fixed in the plastic head by glue. After a period of use, the aging of the glue leads to the loosening of the screw and the plastic head. When the plastic head is stressed, the screw rod comes out of the plastic head, which affects the normal use of the hand screw.

Specification label broadcast representation format: Thread specification d=M12, nominal length L=80mm, and performance level 4.8 equal-length stud bolts are completely marked as: GB 901 M12×80 [1] Product example: Stud studs are generally required After surface treatment, there are many types of bolt surface treatment, commonly used are electroplating, blackening, oxidation, phosphating, electroless zinc flake coating treatment, etc. However, electroplated fasteners account for a large proportion of the actual use of fasteners. Especially in automobiles, tractors, home appliances, instrumentation, aerospace, communications and other industries and fields are more widely used. However, for threaded fasteners, not only a certain anti-corrosion capability is required in use, but also the interchangeability of threads must be ensured, which can also be called screwability here. In order to meet the dual-use performance of anti-corrosion and interchangeability required by threaded fasteners in use, it is very necessary to formulate special plating standards.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: pin positioning pins, trapezoidal screws and bolts, thin head hexagon socket screws, flat round head rivets and other products, we can provide you with suitable fastening products piece solution.
