Description

Technical Field

[0001] The utility model relates to the technical field of steel bar bending machines, in particular to a steel bar bending machine with adjustable angle. Background Art

[0002] At construction sites, steel bars often need to be bent, so steel bar bending machines are commonly used equipment at construction sites. When bending steel bars, straight steel bars are placed between the vertical poles on the turntable of the steel bar bending machine, and the turntable drives the vertical poles to rotate, so that the steel bars are bent. The traditional method of bending steel bars requires the skilled workers to determine the bending angle of the steel bars. In the existing method, an arc-shaped angle ruler is usually installed on the top of the bending machine to observe the bending angle of the steel bars, which is more objective than the traditional bending angle method. However, when bending the steel bars, the workers need to press the steel bars. Therefore, when observing the angle ruler, the workers' line of sight cannot be perpendicular to the angle ruler. Therefore, the angle between the workers' line of sight and the angle ruler is an acute angle, which will cause the observation angle to deviate, affecting the accuracy of the steel bar bending angle.

[0032] Furthermore, the machine body 1 and the rotating disk 21 are the existing model GW40 type steel bar bending machine.

The bending column 23 is installed on the top of the rotating disk 21 by plugging. The bending column 23 is arranged on one side of the fixed column 22. The steel bar is inserted from the middle of the fixed column 22 and the bending column 23. As the rotating disk 21 rotates, the bending column 23 is driven to rotate synchronously. The steel bar is squeezed by the fixed column 22 and the bending column 23, thereby bending the steel bar.

[0034] Furthermore, the angle ruler 3 is an arc-shaped bar, which is arranged on the side of the outer wall of the rotating disk 21. There is a scale on the top of the angle ruler 3, and the scale represents the angle of rotation. The center of the angle ruler 3 coincides with the center of the rotating disk 21, and the bottom end of the angle ruler 3 is fixed to the top of the body 1 by bonding.

[0035] The top of the toggle plate 46 is fixedly connected to the toggle plate 46, and the toggle plate 46 is slidably inserted and connected to the convex groove. The top of the toggle plate 46 is provided with a pushing spring 47 for pushing the toggle plate 46 to move.

[0036] Furthermore, the movable groove is opened along the edge of the angle ruler 3 and is an arc-shaped groove. The movable block 44 is slidably connected with the movable groove so that the movable block 44 can only move along the trajectory of the movable groove. The contact portion between the blocking rod 41 and the plug-in block 43 is fixed by welding. The slot is opened on the side of the top of the connecting rod 42 facing the blocking rod 41. The size of the slot is adapted to the size of the plug-in block 43, so that the fixing bolt 5 is inserted into the slot through the round hole and then threadedly connected to the threaded groove of the plug-in block 43, thereby connecting the plug-in block 43 to the connecting rod 42. The connecting rod 42 is fixedly connected, the contact portion of the blocking rod 41 is fixed by welding, the convex groove is used to install the pushing spring 47 and the pushing spring 47, the horizontal cross-section of the toggle plate 46 is a convex shape, the toggle plate 46 is slidably connected with the convex groove, the magnetic block 45 is an existing magnet, the height of the magnetic block 45 is 1.05 times the straight line height between the top of the body 1 and the bottom of the moving block 44, the bottom end of the toggle plate 46 and the top of the magnetic block 45 are fixed by bonding, so that the toggle plate 46 is installed in the convex groove, and the top and bottom ends of the pushing spring 47 are respectively The top of the inner wall of the convex groove and the top of the toggle plate 46 are bonded and fixed, and the pushing spring 47 is always in a compressed state in the convex groove. When bending the steel bar, the blocking rod 41 is rotated according to the angle at which the steel bar needs to be bent. First, the toggle plate 46 needs to be lifted away from the body 1 so that the toggle plate 46 drives the magnetic block 45 to separate from the body 1, and then the connecting rod 42 is rotated so that the connecting rod 42 is rotated according to the angle scale of the angle ruler 3, and the connecting rod 42 is rotated to the steel bar bending angle, for example, 60 degrees, and then released. The toggle plate 46, under the action of the restoring force of the pushing spring 47, the pushing spring 47 pushes the toggle plate 46, and the toggle plate 46 pushes the magnetic block 45 to be magnetically fixed to the top of the body 1, thereby fixing the position of the blocking rod 41. Because the blocking rod 41 extends to the top of the rotating disk 21, when the bending column 23 bends the steel bar, when the steel bar touches the blocking rod 41, it means that the steel bar is 60 degrees. This method avoids the need for workers to watch the scale at the same time during the steel bar bending operation, and the angle deviation caused by the tilt of the viewing angle.
