Background

The threaded connection is a detachable fixed connection which is widely used, has the advantages of simple structure, reliable connection, convenient assembly and disassembly and the like, and is widely applied to mechanical products and machining equipment. The threaded fastener is used as the foundation and the key for connecting mechanical parts, and is related to the assembly precision of the whole machine and the safety and reliability of operation. How to improve the machining precision and quality of the thread on the premise of ensuring the production efficiency is a problem for studying and discussing by scholars at home and abroad. The cutting type external thread machining technology is widely applied to the field of thread machining at home and abroad. However, when a thread is machined by a cutting method, chatter vibration is likely to occur in the latter half of the cutting operation because the contact length of the cutting edges becomes long. In addition, in the machining process of the cutter, the load at the round corner radius of the cutter point is concentrated and large, so that the cutter is easily abraded, and the precision is influenced.

Besides common turning of threads, thread machining also includes various machining methods such as milling, grinding, tapping, threading and the like. The thread pitch precision of the thread milling can reach 8-9 grades generally, and the surface roughness is R5-0.63 microns. This method is suitable for mass production of threaded workpieces of general precision or rough machining before grinding. The grinding is suitable for grinding precise screw rods, thread gauges, worms, small-batch threaded workpieces, relief grinding precise hobs and the like, has low processing efficiency and is not suitable for mass production. The processing precision of tapping or threading depends on the precision of a screw tap or a die, but the manual operation efficiency of tapping and threading is low, the requirement on the professional skill of an operator is high, and the processing production cost and the efficiency of a tapping machine and a threading machine are low.

The rolling type thread processing method is a processing method for obtaining a threaded fastener by extruding a workpiece with a forming rolling die and plastically deforming the metal, and preferably solves the above-mentioned problems. The method not only improves the production efficiency (the efficiency can be improved by dozens of times or even hundreds of times compared with the common method for turning threads on the lathe), but also can reduce the consumption of cutters and improve the surface smoothness of the threads, thereby improving the processing quality of threaded fasteners. However, the conventional rolling type thread processing has large equipment volume and is clumsy, only a single type of thread can be processed in the processing process, and the processing of double-end studs with various threads cannot be realized. The requirements on the material and the precision of the processing die are higher, and the production cost is greatly increased.

Based on the background, the planetary rolling type thread machining equipment which is flexible and efficient, has a full-automatic production process, can machine various threads and double-end studs is manufactured, and has wide significance for machining the threads. In addition, a feeding device suitable for the processing equipment is designed, and conditions are provided for the equipment to be put into practical production.
