Description
Technical Field
The utility model relates to the technical field of machining, especially, relate to a screw rod feeding device for screw rod processing.
Background
The screw consists of a thread and a cylinder. The screw rod is provided with a long hole along the central line and can be filled with cooling water. The tail part of the screw rod is arranged in the thrust bearing, so that the screw rod is prevented from being pushed out by a reaction force generated during rubber extrusion. The diameter of the screw is slightly smaller than the inner diameter of the steel sleeve of the machine body, namely a gap is formed between the diameter of the screw and the inner surface of the steel sleeve, and the gap is generally controlled to be 0.002-0.004 times of the diameter of the screw. Too small clearance can cause the screw to sweep the chamber, generate abrasion and even generate the phenomenon of locking the screw; too large a gap causes backflow of the sizing material, which affects the extrusion amount, reduces the production efficiency, and also affects the product quality. The thread depth has a direct relation with the production capacity of equipment, the thread depth is large, and under a certain pressure, more glue is extruded. However, the rubber compound is difficult to plasticize and the screw strength is also poor. The screw thread depth is generally controlled to be 0.18 to 0.25 times of the screw diameter. The advancing face of the flight should be perpendicular to the axis of the screw, while the opposite face of the advancing face should have a slope.
