Service HotlineIn another embodiment of Guangdong Yueluo Hardware Industry Co., Ltd., the slotting device 4 includes a motor 41 and a motor 43, the cutting wheel 42 is fixedly arranged at the output end of the motor 41, and the motor 41 drives the cutting wheel 42 to rotate to open the screw. slot, the motor 43 is fixedly arranged on the workbench 1, the motor 41 is arranged on the motor 43, a track 47 is arranged between the motor 41 and the motor 43, the motor 41 can reciprocate through the track 47, and when the screw is slotted, the motor 41 drives the cutting wheel 42 to move in the direction of the screw. When the slotting is finished, the motor 41 drives the cutting wheel 42 to retract. The fixed wheel 48 is arranged at the output end of the motor 43. The fixed wheel 48 is located directly below the cutting wheel 42. The surface of the middle screw is in contact, and the motor 43 drives the fixed wheel 48 to rotate to grind and polish the surface of the slotted screw to make the surface smooth. Preferably, the direction of rotation of the cutting wheel 42 and the fixed wheel 57 is opposite.
Fasteners are a type of mechanical parts that are used for fastening connections and are widely used. They are used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, hydraulics and other industries. This kind of fastener is a widely used mechanical basic part. It is characterized by a wide variety of specifications, different performance and uses, and a very high degree of standardization, serialization and generalization. Therefore, some people also refer to a type of fasteners with existing standards as standard fasteners, or simply as standard parts.
Standard screw is one of the fasteners commonly used for fastening and assembly. Standard screws and flat washers, grade A, and standard spring washers, are used in combination, and are widely used in the assembly of various products. For manufacturers who use combination screws in small and medium batches, the process of combining screws, spring washers and flat washers generally adopts the method of assembling screws by workers' bare hands. This method is tedious and repetitive, wastes human resources, is time-consuming and labor-intensive, and it is difficult to ensure the normal operation of the workshop. assembly progress. The screw assembly machines currently on the market can replace manual assembly screws, but this type of equipment has disadvantages such as bulky size, high cost, complex structure, inconvenient non-standard manufacturing and maintenance, high noise, and power consumption.

A rivet is a part that uses its own deformation or interference to connect the riveted parts in riveting. With the continuous progress and development of science, rivets have been used in many occasions because of their convenient use and reliable connection. The rivet includes a nail head and a stem. The traditional processing mold for the rivet head includes a base, and a nail head forming part is arranged on the base. However, due to the limited service life of the mold, the processing mold of this structure is replaced. It needs to be replaced together with the base, which is a waste of material, which increases the production cost, and the rivet itself is relatively cheap, so this reduces the profit of the enterprise.
