Straightening, shearing and bending machine for steel bars

Abstract

The invention belongs to the field of metal bending equipment, in particular to a straightening, shearing and bending machine for steel bars. The machine comprises a feeding mechanism (12), a shearing / bending component (13), a micro-switch (3) and a shearing / bending motor (1), wherein the hearing / bending component (13) comprises a frame body (14), a camshaft (5), a shearing cam (6) and a bending cam (7); a movable shearing shaft (8) and a bending shaft (9) are arranged in the frame body (14); a shearing knife (20) and a bending head (15) are sequentially fixedly arranged at one end part of the shearing shaft (8) and one end part of the bending shaft (9); a bending fixture (17) is fixedly arranged in the corresponding position of the bending head (15); return springs (16) are fixedly arranged on the shearing shaft (8) and the bending shaft (9); the working end of the micro-switch (3) corresponds to a steel bar channel (18) to be processed; and a cam micro-switch (10) is arranged in the frame body (14). The straightening, shearing and bending machine for the steel bars is convenient for operation, high in degree of automation, safe and reliable.

Description

technical field [0001] The invention belongs to the field of metal bending equipment, in particular to a steel bar straightening, shearing and bending machine. Background technique [0002] Bending is a common process involved in machining, with a wide range of applications. In engineering practice, the steel bars with a diameter in the range of Φ6~Φ12 are straightened and cut into 100mm~200mm steel bar sections, and then bent at 30°~90°. Manual operation mode is generally used. This processing method exists. The following problems: (1) The position of the material is easy to change during the processing, and it is difficult to fix and accurately locate the material; (2) The whole process is labor-intensive and the work efficiency is low; (3) There are large safety hazards in the processing process . Contents of the invention [0003] The invention aims to overcome the disadvantages of the prior art and provide a straightening, shearing and bending machine for steel bars...
