technical field

The invention mainly relates to a numerical control tape winding machine, which is mainly used for the winding and forming processing of wire rods and bar-shaped metal products, and is suitable for the processing of auger and other products that can be used for spiral output.

Background technique

In the traditional processing of the spiral blade pre-winding technology, the wire rod or flat steel is rolled and formed in the mold by using a mold, and then the spiral blade is obtained by shaping in the later stage. This process is relatively traditional. The processing accuracy is relatively strict, and the cost of the mold is high and the loss is large, resulting in the high output cost of the spiral blade. After continuous improvement in the later period, by clamping the spiral winding device on the basis of the lathe, and using the speed ratio formed by the lathe spindle and the feed of the slide plate to process the spiral blade, the accuracy of the modified equipment does not meet the design requirements, and the pitch error after pitch winding is relatively high. Large, manual winding and welding is required after manually inserting the wire rod or flat steel. The pitch variability is small, and only a few pitch ranges can be adjusted. There are processing limitations, and the winding quality and processing efficiency of the spiral blade are unsatisfactory.
