Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-Figure 4 The utility model provides a bending machine for processing round steel materials, including an installation box 1, a forward and reverse control box 4 is arranged on the upper surface of the installation box 1, a bending mechanism 2 is arranged inside the installation box 1, the bending mechanism 2 includes a motor 201, and the motor 201 is arranged inside the left side of the installation box 1, the power output end of the motor 201 is transmission-connected with a rotating shaft 202, a turntable 203 is arranged at the right end of the rotating shaft 202, and the turntable 203 is rotatably installed on the right inner wall of the installation box 1, and a bending protrusion 204 is arranged on the right surface of the turntable 203, and the bending protrusion 204 is provided with two;

[0019] It should be noted that motor 201 uses an 11KW380v motor with a cycloidal pinwheel reducer as the power source, and adopts a motor direct connection type to ensure that steel below 36MM can be processed. The Q235 thick 30MM steel plate welded frame ensures the strength of the whole machine. The setting of the forward and reverse control box 4 facilitates the forward and reverse switching, and is equipped with overload protection and short-circuit protection to ensure the safety of employees during operation.

A rotating shaft 207 is provided on the right inner wall of the installation box 1, and two rotating shafts 207 are provided. The two spur gears 206 are respectively provided on the circumferential surfaces of the two rotating shafts 207, and the ends of the two spur gears 206 away from the spur gear 1 205 are meshedly connected with a spur gear 3 208. A rotating shaft 3 209 is provided in the middle of the spur gear 3 208. The right end of the rotating shaft 3 209 is rotatably installed on the right inner wall of the installation box 1, and a fan blade 210 is provided on the circumferential surface of the left side of the rotating shaft 3 209. A ventilation hole is opened on the right wall of the installation box 1;

[0021] It should be noted that the diameter of spur gear 206 is much smaller than the diameter of spur gear 1 205, while the diameter of spur gear 3 208 is slightly larger than the diameter of spur gear 206, so that when spur gear 1 205 rotates more than half a circle, spur gear 206 can rotate many circles, thereby driving spur gear 3 208 to rotate many circles, thereby enabling fan blades 210 to rotate quickly, so that when the device is bending, fan blades 210 blow air in left and right directions, thereby generating left and right airflow around the device, thereby discharging the heat generated by motor 201 when it is working from around the device, avoiding excessively high temperature around the device affecting the working quality and service life of the equipment, and the generated airflow makes the surrounding area cooler, thereby improving the comfort of the staff.

[0022] In the present embodiment, preferably, a limiting mechanism 3 is provided inside the front end of the installation box 1, and the limiting mechanism 3 includes a rotating rod 301, and the rotating rod 301 is rotatably installed inside the front end of the installation box 1, and a bevel gear 1 302 is provided at the rear end of the rotating rod 301, and the upper end of the bevel gear 1 302 is meshingly connected with a bevel gear 2 303, and the lower end of the bevel gear 2 303 is provided with a threaded rod 304, and the circumferential surface of the threaded rod 304 is threadedly connected with a lifting block 305, and the right end of the lifting block 305 is provided with a positioning block 306, and a positioning wheel 307 is rotatably installed inside the lower end of the positioning block 306, and a fixing plate 308 is provided below the positioning wheel 307, and the fixing plate 308 is provided on the right outer wall of the installation box 1;

The lower end of the threaded rod 304 is rotatably installed inside the fixed block 5. The setting of the lifting slot 6 provides a movable space for the lifting block 305, so that the lifting block 305 can smoothly drive the positioning block 306 to move vertically.

[0024] Among them, most of the bending machines in the existing market work from the front, without a side grip design, which makes it easy for steel to break and injure people during processing. This bending machine adopts a side grip working mode, with a very simple working principle, reliable operation, and high safety. The machine is a cycloidal pinwheel two-stage reducer with a reduction ratio of 187 and a speed controlled below 10 rpm. The processing diameter of 20MM-36MM ground angle bolts does not require heating, and the workload can produce about 100 pieces of 24MM ground angle bolts per hour. The production efficiency is high, safe and reliable, and its economic benefits are also high. For example, piecework wages save 1.2 yuan per piece, and electricity costs and other losses save 1.5 yuan per piece. Each belt conveyor is equipped with an average of 200 large and small ground angle bolts, and there are about 30 belt conveyors a year. It is estimated that the annual labor wages can be saved by 16,200 yuan, and the efficiency is more than 2.5 times higher than that of the old process.

[0025] The working principle and use process of the utility model are as follows: when the device is used, first, the staff is located in front of the installation box 1, and the rear end of the steel is placed in the middle of the two bending protrusions 204, and its front end extends forward through the gap between the lower end of the positioning wheel 307 and the upper end of the fixing plate 308, and then the rotating rod 301 is rotated, and the rotating rod 301 drives the bevel gear 2 303 and the threaded rod 304 to rotate through the bevel gear 1 302, so that the lifting block 305 drives the positioning block 306 and the positioning wheel 307 to move vertically downward, and after the lower end of the positioning wheel 307 abuts against the upper surface of the steel, the adjustment work is completed, and the steel can be limited to avoid falling during the bending process of the steel;

[0026] Then start the motor 201, and the motor 201 drives the shaft 1 202, the turntable 203 and the two bending protrusions 204 to rotate, so that the bending protrusions 204 bend the steel into shape. At the same time, the rotation of the shaft 1 202 will also drive the spur gear 1 205 to rotate, and the rotation of the spur gear 1 205 drives the spur gear 2 206, the shaft 2 207 and the spur gear 3 208 to rotate, and then drives the shaft 3 209 and the fan blades 210 to rotate, so that the fan blades 210 blow air in the left and right horizontal directions, so that the air around the motor 201 circulates quickly, and the temperature around the motor 201 is prevented from being too high and affecting the operation of the motor 201. After the bending is completed, the rotating rod 301 is rotated in the opposite direction, so that the positioning block 306 drives the positioning wheel 307 to move upward, and the processed steel can be removed from the right side surface of the installation box 1.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
