Abstract

The invention discloses a winding device and method for a welded multi-head auger rod, which comprises a lathe, a faceplate installed on the main shaft of the lathe, a wing clamp installed on the faceplate, and two supporting plates arranged on the base of the lathe Fixture: the variability of parameters such as pitch can be realized by adjusting the angle of the supporting plate clamp for winding the fins, the relative position of the two fin clamps, the rotation speed of the rotating shaft and the moving speed of the supporting plate clamp; at the same time, it is convenient to wind the double auger Rod; Directly winding the helical fin on the drill pipe and spot welding it on the lathe can ensure the fitting accuracy requirements of the drill pipe and the fin and the final pitch accuracy and other requirements. The method of the invention has the advantages of simple and convenient operation, high processing precision, high efficiency and low cost.

Description

technical field [0001] The invention belongs to the field of winding auger rods, and relates to a winding device for auger rods, in particular to a winding device and method for a welded multi-head auger rod. Background technique [0002] The auger drilling technology has become the main technical means of gas drainage drilling in soft and outburst coal seams. The auger rod is an important tool for auger drilling. According to its processing method, it is divided into a welded auger rod and an integral auger rod. The welded auger rod is welded by a split helical blade and a core rod. The helical fins of welded auger rods are formed by winding steel strips on a reference drill rod using a lathe. After the helical fins are wound and shaped, they are welded with the auger core to form a complete auger. Welded auger rods include single auger rods and double auger rods, the latter being more difficult to produce. It is of great significance to develop a special auger rod windi...
