Description

Technical Field

[0001] The utility model relates to the technical field of steel bar bending hoop equipment, in particular to a steel bar bending hoop device. Background Art

[0002] Rebar is a very strong material that can effectively improve the structural strength of concrete. A large number of rebars are used in the construction process. After these rebars are purchased, they need to be bent by a bending device, such as a rebar bending machine. Rebar bending machines are mainly used for the processing and shaping of rebars at construction sites. They are widely used because of their large output and simple operation.

[0003] When the traditional steel bar hoop bending machine is in use, although moving wheels are installed at the bottom of the hoop bending machine to improve the convenience of moving the hoop bending machine, after the hoop bending machine is moved to the designated location, due to the lack of an effective supporting mechanism on the hoop bending machine, the hoop bending machine is prone to displacement during use, affecting the stability of the hoop bending machine. When the traditional hoop bending machine is in use, although louver holes are opened on the wall of the hoop bending machine, the louver holes can be used to ventilate and dissipate heat for the internal driving device of the hoop bending machine. However, when the hoop bending machine is used outdoors for a long time, flying dust and other debris in the outdoor air will adhere to the louver holes, thereby affecting the ventilation effect of the louver holes and reducing the service life of the electrical components inside the hoop bending machine.

[0036] Embodiment 2, based on embodiment 1, as Figure 1 , Figure 2 and Figure 5 As shown, it also includes a cleaning mechanism 3, which is arranged on the front end surface of the hoop bending machine body 1, and the cleaning mechanism 3 is located outside the louver hole 106; the cleaning mechanism 3 includes a fixed support plate 301, a transverse guide rod 302, a cleaning brush 303, a reciprocating screw rod 304, a small motor 305, a rain cover 306 and a screw nut 307, the number of the fixed support plates 301 is two, and the two fixed support plates 301 are respectively fixedly connected to the left and right sides of the front end surface of the hoop bending machine body 1; two transverse guide rods 302 are fixedly connected between the opposite surfaces of the two fixed support plates 301 in an upper and lower symmetrical shape, and the cleaning brushes 303 are slidably connected to the outside of the two transverse guide rods 302; the reciprocating screw rod 304 is rotatably connected to the two fixed support plates 301, and the outside of the reciprocating screw rod 304 is connected to the screw rod through a spiral groove Nut 307; the screw nut 307 is fixedly installed in the middle of the cleaning brush 303; the small motor 305 is fixedly installed on the right side of the front end surface of the hoop bending machine body 1, and the left end of the rotating shaft of the small motor 305 is fixedly connected to the right end of the reciprocating screw 304, and the small motor 305 is electrically connected to the control box 104; the rain cover 306 is fixedly installed on the right side of the front end surface of the hoop bending machine body 1, and the rain cover 306 is located above the small motor 305; through the cooperation of the human body sensing switch 103, the control box 104 and the cleaning mechanism 3, when the human body sensing switch 103 senses the signal of the presence of the human body, the control box 104 can control the operation of the cleaning mechanism 3, thereby sweeping away the flying dust and other debris near the louver hole 106 on the front end surface of the hoop bending machine body 1, so as to avoid affecting the ventilation effect of the louver hole 106.

[0037] The working principle of this embodiment: when in use, first move the hoop bending machine body 1 to the use position through the moving wheel 105 at the bottom of the hoop bending machine body 1. After the hoop bending machine body 1 is moved to the designated location, the staff manually turns the rotating handwheel at the upper end of the left support screw 203 (the right support screw 203 can also be rotated) to make the left support screw 203 start to rotate, and then a first bevel gear on the left side drives a second bevel gear on the left end of the synchronous shaft 5 to rotate, and then the synchronous shaft 5 and the second bevel gear on the right side of the synchronous shaft 5 drive the right support screw 203 to rotate at the same time. At this time, the two lifting plates 202 are both driven by the support column 204 to move downward in a straight line under the action of the thread. When the bottom end surface of the circular plate at the lower end of the four support columns 204 contacts the ground, continue to rotate the left support screw 203, and finally make the moving wheel 105 away from the ground.

[0038] Then, according to the diameter of the steel bar, the distance between the movable plate 404 and the fixed plate 405 is adjusted. When adjusting, it is only necessary to manually rotate the adjusting screw 407, so that the adjusting screw 407 can move the movable plate 404 forward and backward under the action of the thread. After adjustment, the steel bar is passed through the gap between the movable plate 404 and the fixed plate 405. The limiting effect of the movable plate 404 and the fixed plate 405 replaces manual holding of the steel bar, thereby improving the safety of the hoop bending machine body 1 when in use.

[0039] Then start the internal driving device of the hoop bending machine body 1, and use the internal driving device of the hoop bending machine body 1 to drive the core shaft 101 and the turntable 102 and the turntable 102 to rotate clockwise at a specified angle, and then use the turntable 102 to bend the steel bars with the bending parts on the turntable 102.

[0040] When the staff walks in front of the human body sensing switch 103 to observe the bending of the steel bars, the human body sensing switch 103 will transmit the signal of the presence of the human body to the control box 104, and then the small motor 305 will be started through the control box 104, and then the reciprocating screw rod 304 will be rotated by the small motor 305. Then, at this time, the screw nut 307 moves back and forth with the cleaning brush 303 under the action of the spiral groove on the reciprocating screw rod 304, thereby cleaning away the flying dust and other debris near the louver hole 106 on the front end face of the hoop bending machine body 1.
