A high-precision thread rolling machine and thread rolling method thereof

Abstract

The invention relates to a high-precision thread rolling machine, which includes a fuselage and a working table arranged on the fuselage. A fixed seat and a moving seat are respectively arranged on the working table, and the opposite sides of the fixed seat and the moving seat are respectively provided with The thread rolling shafts arranged in parallel at intervals are respectively provided with two thread rolling discs arranged at intervals relative to each other, and the fixed seat and the moving seat are respectively provided with two driving drives for driving the rotation of the two thread rolling shafts. There is a motor on the working table for driving the moving seat to approach or move away from the fixed seat, and the two thread rolling shafts are provided with a cylindrical steel pipe for cooperating with extrusion and positioning, and as the two thread rolling discs approach each other to maintain the column The main axis of the shaped steel pipe is parallel to the main axis of the two rolling discs, and then the thread rolling pre-extrusion positioning assembly is rolled. Compared with the prior art, the processing thread rolling deviation is avoided, the thread rolling quality is improved, the production qualified rate is greatly improved, the defect rate is reduced, raw materials are saved, and production costs are reduced.

Description

technical field [0001] The invention relates to a thread rolling machine, in particular to a high-precision thread rolling machine and a thread rolling method thereof. Background technique [0002] At present, in the process of producing mechanical parts, it is necessary to process and roll the cylindrical steel pipe of its material. The cylindrical steel pipe is the optical axis, so as to cooperate with the further processing. A threaded shaft, two drive motors respectively used to drive the two threaded rolling shafts to rotate, a pair of threaded rolling discs driven by the threaded rolling shafts, a threaded rolling disc seat for positioning one of the threaded rolling discs on the machine body, and a It is composed of a drive assembly that drives another thread rolling disc to approach or move away from the thread rolling disc fixed on the machine body. The thread rolling die can be installed on the thread rolling disc base to process. The equipment is characterized by ...

AI Technical Summary

Problems solved by technology

When the existing thread rolling machine is produced, the cylindrical steel pipe inserted between the two thread rolling discs for thread rolling is not close at the same time because the two thread rolling discs are not close at the same time, and the main axis of the cylindrical steel pipe is in line with the two thread rolling discs. It is difficult to keep the main axis parallel, which leads to the deviation of the processing thread rolling, the quality of the thread rolling is greatly reduced, the production failure rate is greatly increased, and the high defect rate wastes raw materials and increases the production cost, and the existing thread rolling machines mainly use The cylindrical steel pipe is inserted between the two thread rolling discs by hand-held manual feeding, and the rolling process is performed. The efficiency of thread rolling is low, and there is no supporting positioning device to coordinate with the rotating cylindrical steel pipe to position and then process the thread rolling. The quality of the wire is low, and in the process of manual operation, it is easy to injure the hands of the wire rolling disc when it is manually fed into and pulled out. In severe cases, the corresponding extrusion phenomenon occurs, and the safety cannot be guaranteed. make improvements
