GSK 988TB system making parallel twin screws



Processing of parallel twin screws in the same direction;

The customer provided the drawing: from the end view, the screw is two arcs tangent to the center and another arc, and then a double-headed screw is formed according to the workpiece rotation.










solution


Drawing analysis, the structure of the end face of the parallel bidirectional screw is as follows:

Analysis of each point in the figure:

Point O: the center of the screw,

Point O1: the center point of the end tooth profile arc,

OX1: screw outer diameter,

OXn: inside diameter of screw,

Other X points: Calculate points equally, that is, X coordinate for each infeed;





Calculation method: According to various conditions, the radius of the tooth-shaped arc (that is, the value of X1O1) can be calculated, and then the values of the triangle X1O1O can be calculated, and then X1 can be changed to the corresponding halving points such as X2, X3, etc. to obtain each X value ; And the corresponding Z value is the corresponding equal component. This achieves the corresponding programming;

Processing method: According to the analysis of the above-mentioned end surface trajectory, the corresponding trajectories can be obtained. First, rough turning, 0.5mm unilateral machining, and then leave 0.1mm fine turning, which can be completed.
