Building steel bar end thread rolling mechanism

Abstract

The invention provides a building steel bar end thread rolling mechanism. The mechanism comprises a base, a motor rolling integrated device is fixed on the middle part of the base, rib stripping mechanisms are symmetrically connected with two sides of the motor rolling integrated device, the rib stripping mechanisms are fixed in a shell body, the shell body is fixed on the base, feeding mechanismsare arranged on the outer sides of the rib stripping mechanisms, clamping mechanisms are installed on the feeding mechanisms, the motor rolling integrated device comprises a motor base, a motor stator is fixed on the inner wall of the motor base, a rotatable motor rotor with a built-in permanent magnet is arranged in the motor base, three thread rolling wheels which are evenly distributed are meshed with the inner ring of the motor rotor, and the three thread rolling wheels are installed on three rotating shafts and are supported by a planet carrier. After rib stripping is completed, a steelbar is controlled by a second servo motor to be bitten into the front ends of the thread rolling wheels, the steel bar to be rolled, the three thread rolling wheels and the inner ring of the motor rotor form a planetary gear train, and the motor rotor rotates to drive the thread rolling wheels to rotate to complete rolling. The thread rolling mechanism improves the machining efficiency, is not prone to deviation and is high in thread rolling quality.

Description

Technical field[0001]The invention belongs to the technical field of construction machinery and equipment, and in particular relates to a thread rolling mechanism for steel bar ends for construction.Background technique[0002]Threaded connection is one of the most common connection methods in the field of construction machinery. As an important part of reinforced concrete structures, building steel bars may need to be processed at any time at the construction site. The level of technology and thread rolling quality directly affect the safety of concrete structures. The most widely used thread processing methods are cutting processing and rolling processing. Compared with thread cutting processing, thread rolling is an equal-material and chip-free forming process. Its essence is the pressure of the workpiece on the rolling tool. Under the plastic deformation, the corresponding thread is rolled. Because the steel bar at the bottom of the thread is not cut, but rolled to produce plastic...

AI Technical Summary

Problems solved by technology

However, the traditional rib stripping and rolling machine can only process one piece in a single operation, and the processing efficiency is low; and the rib stripping and rolling device is not uniformly stressed during the movement process, and it is prone to deviation, resulting in low quality of steel bar rolling
