High-precision aluminum profile bending mechanism

Abstract

The invention discloses a high-precision aluminum profile bending mechanism which comprises a rack, a main shaft tube arranged on the rack, a first gear arranged on the main shaft tube, a servo motor arranged on the rack, a second gear connected to the servo motor and a rack plate slidably arranged in the rack, wherein a first rack meshed with the second gear is arranged at the bottom of the rack plate, and a second rack meshed with the first gear is arranged at the left end of the rack plate; a sliding plate die is arranged on the outer side of the rack; and a mounting seat is arranged on the rack, a bearing is arranged in the mounting seat, the main shaft tube is in close fit to the bearing, a rotating shaft is arranged in the main shaft tube in a penetrating manner, the lower end of the rotating shaft is connected to a lifting mechanism, a wheel die group consisting of a plurality of mutually independent wheel dies is sleeved at the upper end of the rotating shaft, and a pressing and blocking mechanism is arranged at the top of the rotating shaft. The high-precision aluminum profile bending mechanism has the advantages that the service life is prolonged, aluminum profile demolding is facilitated, and the bending precision and the bending quality of the aluminum profile are greatly improved.

Description

technical field [0001] The invention relates to a high-precision aluminum profile bending mechanism. Background technique [0002] The bending mechanism in the aluminum profile bending machine includes: a frame, a main shaft is arranged on the frame, a wheel mold is arranged on the main shaft, and a wheel groove capable of accommodating the inner wall of the aluminum profile is arranged on the wheel mold. A pipe bending arm connected to the main shaft is provided on the outer side of the pipe bending arm. A sliding plate mold aligned with the wheel mold is provided on the pipe bending arm. A groove capable of accommodating the outer wall of the aluminum profile is provided on the sliding plate mold. A first wheel is provided on the main shaft. The sprocket is provided with a reducer on the frame, and a second sprocket is arranged on the reducer. The first sprocket and the second sprocket are connected by a chain, and the reducer can drive the second sprocket to rotate throug...

AI Technical Summary

Problems solved by technology

The above-mentioned bending mechanism has the following disadvantages: 1. During the bending process, there is a large friction force between the chain and the first and second sprockets, and the sprockets are easy to wear the chain, which easily increases the pitch of the chain , so that it is easy to be out of touch with the sprocket and affect the bending accuracy, and even the chain may break, which is not only prone to production accidents, but also greatly reduces the service life of the bending mechanism; 2. After the bending is completed , the aluminum profile will be tightly stuck in the wheel groove of the wheel mold, and the demoulding work cannot be performed well, and the aluminum profile is easily damaged during the forced demoulding process; 3. The wheel groove of the wheel mold and the groove of the sliding formwork Only the upper and lower ends of the aluminum profile can be clamped, the ribs on the inner wall of the aluminum profile cannot be clamped, and the ribs on the inner wall are prone to warping during the bending process
