Description

Technical Field

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

[0002] Rebar is a common building material and is very commonly used in construction projects. It is usually in the form of long strips. During use, according to actual construction needs, the rebar also needs to be processed accordingly before it can meet the needs of use. The most common process is to bend the rebar.

[0003] The bending of steel bars is carried out by a bending machine. The steel bars are usually placed on a workbench with two partitions at a certain distance. The steel bars are extruded by a torture die head. The bending state of the steel bars is determined by the die. However, this method requires frequent replacement of the bending extrusion head when different bending requirements are required, which is not convenient enough. Utility Model Content

[0004] In view of the problems existing in the prior art, the utility model discloses a steel bar bending machine with an angle control function. The technical scheme adopted is that it includes a workbench, a steel bar placement boss, a front protection, a rear column, an open groove, an I-shaped rod, a locking screw, a bending and extrusion mechanism, a movable plate, an angle limiting mechanism, a rotating shaft and an angle plate. The left and right ends of the rear side of the upper surface of the workbench are integrally formed with steel bar placement bosses, and the steel bars are placed through the steel bar placement bosses on the left and right sides. A front protection is arranged on the steel bar placement boss, and a rear column is integrally formed at the rear end of the steel bar placement boss. An open groove is opened in the left and right directions of the rear column. The I-shaped rod is placed in the open groove in cooperation. The position adjustment of the I-shaped rod can adjust the space between the barriers on the rear side of the steel bars. The position of the I-bar is locked by a locking screw. When bending, the front protection and the I-bar jointly protect the two ends of the bending of the steel bar. The movable plate is installed through a bending and extrusion mechanism arranged on the workbench. Two rotating shafts are fixed on the movable plate. The rotating shafts are rotatably connected to the angle plate. The inner side of the angle plate is contacted and limited with an angle limiting mechanism arranged on the movable plate. When bending, the bending and extrusion mechanism drives the movable plate to move in the direction of the steel bar. The rotating shaft first contacts the steel bar and pushes it back to bend. In this process, the steel bar is bent and squeezed to the angle plate. The angle plate limits the bending degree of the steel bar, and the angle plate is limited by the angle limiting mechanism. Therefore, the bending degree can be determined by adjusting the angle limiting mechanism.

[0005] As a preferred technical solution of the utility model, the front side protection includes a boss mounting groove, a protection mounting screw, a knob and a protection plate. The upper surface of the steel bar placement boss is provided with a boss mounting groove. The protection mounting screw is rotatably installed in the boss mounting groove and driven by the knob. The protection plate is placed in the boss mounting groove and installed in cooperation with the protection mounting screw. The position of the protection plate is changed under the manual drive of the knob to play a normal protective role for steel bars of different diameters.

[0006] As a preferred technical solution of the utility model, the bending and extrusion mechanism includes a middle mounting groove, an extrusion moving screw and a driving motor. A middle mounting groove is opened in the middle of the upper surface of the workbench, in which an extrusion moving screw driven by a driving motor arranged on the front side of the workbench is rotatably installed. A lower protrusion is integrally formed in the middle of the rear side of the bottom of the movable plate. The lower protrusion is placed in the middle mounting groove and installed in cooperation with the extrusion moving screw. Driven by the driving motor, the extrusion moving screw is driven to rotate so that the lower protrusion installed in cooperation with it moves with the movable plate, and moves toward the direction of the steel bars to extrude and bend the steel bars with the rotating shaft above it.

[0007] As a preferred technical solution of the utility model, the angle limiting mechanism includes a movable plate mounting groove, a bidirectional lead screw, a stepping motor, a mounting block and a limiting column. A movable plate mounting groove is opened on the rear side of the upper surface of the movable plate, in which the bidirectional lead screw is rotatably installed and driven by a stepping motor. There are two mounting blocks, both of which are placed in the movable plate mounting groove and symmetrically installed with the bidirectional lead screw. A limiting column is integrated on the rear side of the mounting block, and the limiting column is located on the rear side of the body opposite to the angle plate.

[0008] As a preferred technical solution of the utility model, the drive motor and the stepper motor are both powered by external wiring and controlled by an intelligent controller, and the angle plate is made of rigid material.

[0009] The beneficial effects of the utility model are as follows: by arranging an angle limiting mechanism on the movable plate, the bending position of the steel bar can be limited when the steel bar is extruded and bent, and the angle limiting mechanism can be adjusted as needed so that the limiting position of the steel bar can also be adjusted as needed. In actual use, there is no need to frequently replace the mold to meet different bending requirements. BRIEF DESCRIPTION OF THE DRAWINGS

The steel bar placement boss 2 is integrally formed at the left and right ends of the rear side of the upper surface of the workbench 1, and the front side protection is arranged on the steel bar placement boss 2. The rear side column 7 is integrally formed at the rear end of the steel bar placement boss 2. The rear side column 7 is provided with an open groove 71 penetrating in the left and right directions. The I-shaped rod 8 is cooperatively placed in the open groove 71, and the position of the I-shaped rod 8 is locked by the locking screw 9. The movable plate 13 is installed by the bending and extrusion mechanism arranged on the workbench 1, and two rotating shafts 19 are fixed on the movable plate 13. The rotating shaft 19 is rotatably connected to the angle plate 20, and the inner side of the angle plate 20 is contacted and limited with the angle limiting mechanism arranged on the movable plate 13.

The protection plate 6 is placed in the boss mounting groove 3 and installed in cooperation with the protection mounting screw 4.

[0017] As a preferred technical solution of the utility model, the bending extrusion mechanism is specifically arranged in such a way that a middle mounting groove 10 is opened in the middle of the upper surface of the workbench 1, in which an extrusion moving screw 11 driven by a driving motor 12 arranged on the front side of the workbench 1 is rotatably installed, and a lower protrusion is integrally formed at the middle of the rear side of the bottom of the movable plate 13, and the lower protrusion is placed in the middle mounting groove 10 and installed in cooperation with the extrusion moving screw 11.

[0018] As a preferred technical solution of the utility model, the angle limiting mechanism includes a movable plate mounting groove 14, a bidirectional lead screw 15, a stepping motor 16, a mounting block 17 and a limiting column 18.

Therefore, the bending degree can be determined by adjusting the angle limiting mechanism. The stepping motor 16 drives the rotation of the bidirectional screw 15 to change the position of the limiting column, thereby realizing the change of the limiting position of the angle plate 20.
