Roll bending machine

Abstract

Provided is a roll bending machine. A squeezing device is designed on one edge of a roll bending die, so that roll bending is achieved as full-automatic integration production. The squeezing device comprises a wood board, an ejecting roller, ejecting wheels with center rods, an air cylinder and worms, wherein the ejecting roller is transversely placed in an Y-shaped mode, the center rods of the ejecting wheels are fixed to the upper portion of the air cylinder and the lower portion of the air cylinder respectively, one side of each ejecting wheel is connected with the air cylinder, the other side of each ejecting wheel is arranged in a clamping groove of the ejecting roller, the worms are in a transverse L shape, one end of each worm is fixed to the air cylinder, the other end of each worm is located on the ejecting roller, and the wood board is arranged on one side of the ejecting roller. The air cylinder generates power so that roll bending can be conducted on a strip, the power generated by the air cylinder is large, the wood board is additionally arranged at the front end of the ejecting roller, a pressing block is adopted, so that pressure generated by the air cylinder is evenly distributed on a workpiece, the loss produced when the ejecting roller squeezes a fixing block is reduced, manpower of workers is reduced, and meanwhile the roll bending effect is improved.

Description

technical field [0001] The invention relates to a device in the technical field of plate processing mechanical equipment, in particular to a roll bender device. Background technique [0002] In actual production, it is often necessary to bend the V-shaped bars of the track, vehicle, and apron arc grille. The main problem in the bending process is that the partial and entire sections deviate from the predetermined position, resulting in the curvature of the V-shaped bars after bending. The quality is poor, and it is prone to wrinkles and torsion. However, since there is no special bending equipment, the bending of the bar is usually carried out by workers around the rolling die. However, the efficiency of manual bending is low, which increases the cost of bending parts, and the bending processing cycle is long, the production efficiency is low, and the quality and quantity are difficult to meet mass production. Contents of the invention [0003] In view of the above existi...
