As the preferred embodiment of the above-mentioned embodiment, the motor 41 is provided with a thruster 46 that moves the cutting wheel 42 toward the conveying device 3. When the screw needs to be slotted, the thruster 46 generates a thrust toward the screw, and the motor 41 generates a thrust in the direction of the screw. Under the action, the groove is moved along the track 47 toward the screw. The other end of the motor 41 is provided with a bearing 45, and the output end of the motor is provided with a special-shaped wheel 44. The special-shaped wheel 44 is geared to the bearing 45. The wheel 42 is close to or away from the conveying device 3. When the grooving is completed, the special-shaped wheel 44 rotates and drives the bearing 45 to generate the opposite force from the above-mentioned thrust, so that the motor 41 moves back to the initial position along the track 48.
The main purpose of the screw is to make the industrial product form a fixed one. In use, it often happens that the teeth cannot be closely attached, the screw head will be broken if the screw is locked too hard, or the tooth pattern is not properly locked, etc., and the use conditions are not met, all of which are quality. the problem of accuracy. Screws are mass products, not handmade works of art. In mass production, the purpose is to achieve high-precision and stable quality and popular prices to supply consumers. The accuracy of screws is usually 6g, and the rough screws used in construction projects are 14g. The value of screws is very important. In the world, there are examples of automobile factories going bankrupt because of poor screw quality; there are also examples of planes falling and vehicles being overturned because of poor screw quality.
Pre-embedded copper nuts with straight pattern/twill pattern/herringbone embossing and other various anti-skid patterns can be completed at one time by automatic lathes. More complex copper nuts are processed by forming knives and table turning/tapping. Many products processed after machining are relatively simple reticulated copper nuts and straight-grained copper nuts, which are made of C3604 easy-turning brass. The surface pattern is directly drawn from the original bar, and the pattern is full and the tooth peak and bottom are clearly visible. Injection molding into plastic parts Afterwards, it can bear more high torque.
A rivet is a nail-shaped object used to connect two parts with a through hole and a cap at one end. It is mainly used in riveting to connect the riveted parts by its own deformation or interference.
