the traction mechanism (8) comprises a support frame (32) fixedly connected to the workbench (1), a second driving motor (33) is fixedly connected to the support frame (32), a winding sleeve (34) is coaxially and fixedly connected to a driving shaft of the second driving motor (33), one end of the winding sleeve (34) is rotatably connected with a connecting column (35), the connecting column (35) is fixedly connected with the support frame (32), a connecting rope (36) is fixedly connected to the winding sleeve (34), and one end of the connecting rope (36) penetrates through the second lapping table (29) and extends to a first sliding groove (9) to be fixedly connected with the first sliding block (10); one end, departing from the electromagnetic heating ring (30), of the fixing block (31) is fixedly connected with a fixing frame (37), a guide wheel (38) is rotatably connected to the fixing frame (37), and the connecting rope (36) is guided into the first sliding groove (9) through winding of the guide wheel (38); the working process of the metal section straightening machine is as follows:
1) an operator inserts steel needing to be straightened into the second fixing ring (26) and then sends the steel into the first fixing ring (11), impurities on the surface of the steel are gradually scraped and removed by the cleaning soft plate (27) and fall on the bearing plate (28) or outside the bearing plate, then the threaded ring (14) is rotated to gradually tighten the inclined plate (13) to clamp the steel, after clamping is finished, the second driving motor (33) is started to gradually drive the coiling sleeve (34) to coil the connecting rope (36), and the connecting rope (36) drives the steel to move in the straightening groove (3) by dragging the first sliding block (10) and gradually insert the steel into the electromagnetic heating ring (30);
2) meanwhile, the second sliding block (19) is driven to move through the connecting frame (22), so that the spring (21) is extruded, after steel is completely inserted into the electromagnetic heating ring (30), the electromagnetic heating ring (30) is started to rapidly heat the steel, substances on the surface of the steel are carbonized or decomposed and peeled off through high-temperature heating, the second driving motor (33) rotates in the reverse direction after the steel is heated for 3-4s, the first sliding block (10) is gradually reset under the action of the spring (21), and at the moment, the hydraulic rod (23) is started to drive the hydraulic rod (23) to extrude and straighten the steel in the straightening groove (3);
3) in the process of extrusion straightening, a toothed ring (12) is meshed with a gear (16), a first driving motor (15) is started to drive the toothed ring (12) to rotate, a round pipe-shaped section rotates at a constant speed, a square pipe-shaped section is extruded correspondingly according to the number of end faces of the square pipe-shaped section, and steel is pressed and straightened uniformly under the driving of the toothed ring (12) turning for a circle, so that the straightening operation is completed.
