Tubular metal bending equipment with adjustable bending angle for metal forming

Abstract

The invention discloses tubular metal bending equipment with an adjustable bending angle for metal forming. The equipment comprises a bearing mechanism and a locating and clamping mechanism, wherein the locating and clamping mechanism is mounted on the upper end face of the bearing mechanism. According to the equipment, a fixing groove is formed in the upper end of the side, close to an arc-shapedworkbench, of a main bearing table, and a plurality of rolling shafts are arranged in an inner cavity of the fixing groove; tubular metal can be firstly placed in the fixing groove before being bent,a bending assembly returns to the initial position, meanwhile, the inner side of a bending piece makes contact with the tubular metal, and the tubular metal is fixed; during bending, a servo motor and a rotating motor are started,the fixed tubular metal is driven to be bent by the arc movement of an arc-shaped electric sliding block in an arc-shaped sliding groove and the rotation of an arc-shaped rotating disc, the servo motor and the rotating motor can be stopped at any time in the moving process of the arc-shaped electric sliding block, and therefore the purpose of adjusting the bending angle is achieved; and compared with a traditional manual bending mode, the efficiency and the automation level are higher.

Description

technical field [0001] The invention relates to the technical field of bending devices, in particular to tubular metal bending equipment for metal forming with adjustable bending angles. Background technique [0002] Metal bending processing, the bending and forming of metal sheets are carried out on the bending machine, the workpiece to be formed is placed on the bending machine, the brake shoe is lifted by the lifting lever, the workpiece slides to the appropriate position, and then the brake is applied The shoe is lowered onto the workpiece to be formed, and the metal is bent and formed by applying force to the bending lever on the bending machine. The minimum bending radius is a function of the ductility and thickness of the formed metal. For aluminum sheets, the bending radius of the metal is greater than the thickness of the sheet. When bending, due to a certain amount of springback, the bending angle of the metal is slightly larger than the required angle, and the be...

Problems solved by technology

The existing bending methods are mainly carried out manually, which has low efficiency, high labor intensity and poor safety

The body of the traditional bending equipment is large in size, poor in safety performance, and inconvenient to move. The body of the traditional bending equipment is fixed, which is not convenient for fixing the metal, and it is not convenient to adjust the length of the metal according to the actual situation. Adjustment, the traditional bending equipment body is not easy to bend metal, and it is not convenient to adjust the angle of metal bending. Pipe bending machine is a commonly used pipe processing equipment. There are many types of pipe bending machines For example, the pipe bending machine disclosed in the Chinese patent with the publication number of 110479813A includes a workbench, an active rotating part, a passive rotating part, a clamping device and a driving device for driving the rotating part of the active rotating part, and the active rotating part and the The passive rotating parts are respectively mounted on the workbench, the outer walls of the active rotating part and the passive rotating parts are provided with accommodating grooves on the same horizontal plane respectively, and the clamping device is installed on the A clamping hole is formed on the active rotating part and between the accommodating groove opposite to it. The output end of the driving device is connected to the active rotating part. The metal bending equipment mentioned above cannot be adjusted in time when it is formed. Bending angle, and the metal is prone to slipping during processing
