Requirements For The Type And Shape Of Screws For Automatic Screw-driving Machines

Jun 22, 2022

What kind of screws can the automatic locking screw machine lock? What are the characteristics of the request screw? The rules of the automatic screw machine for screws are as follows: screw length rules: the total length of the screw must exceed 1.3 times the straight diameter of the screw pad.


Whether the screw has a gasket: If the screw has a gasket, and the gasket is beyond the screw gasket, then the diameter of the gasket should be calculated initially, so as to prevent the screw from rotating in the feeding tube to the point where there is no way to properly remove the screw. Blow it out and lock it well; if the full length of the screw must exceed 1.3 times the straight diameter of the screw pad, then the feeding method should also use suction or other methods, etc.


External thread of the screw: The external thread of the screw is different. There are self-tapping clamping screws with triangular teeth. This kind of screw has the same pitch and angle as the metric external thread, but the cross section is a triangle with D and C values. There are 2 main parameters that control the clamping, which can override the clamping effect.
