Description

Technical Field

[0001] The invention relates to the technical field of steel bending equipment, in particular to a bending equipment for forming building steel. Background Art

[0002] Rebar is a commonly used building material in engineering construction. During the construction process, the rebar needs to be bent by a bending machine. The rebar often needs to be bent into specific shapes or angles to meet the use needs of different building locations.

[0003] However, in order to prevent the steel bars from curling up, traditional bending machines generally require workers to hold the steel bars and fix them during the bending process. Therefore, if an accident occurs during the bending process, it is easy to injure the workers, and the operation safety is low. At the same time, since the steel bars need to be held in hand all the time, it is not convenient to perform other operations, and the convenience of use is poor. During the bending process, the axle on the bending machine will move toward the steel bars and contact the steel bars to bend the steel bars. When the axle moves at a faster speed and contacts the steel bars, a collision will occur. At this time, the motor inside the bending machine will instantly receive a large reverse resistance, which can easily cause damage to the motor. When a batch of steel bars needs to be bent, it is often necessary that the distance between the bending point of each steel bar and the distance between the ends of the steel bars are equal. Since traditional bending machines do not have positioning devices, it is necessary to rely on the experience of the workers to adjust the position of the bending point, which is prone to deviations and poor stability in use.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figure 1-Figure 8As shown, a bending device for forming building steel materials described in the present invention comprises a bending machine body 1, a support plate 2 is fixedly connected to the bending machine body 1, a fixing structure 3 is provided on the support plate 2, a blocking structure 4 is provided on the support plate 2, a plurality of guide rollers 5 are rotatably connected to the support plate 2, a bending structure 6 is provided on the bending structure 6, an adjusting structure 7 is provided on the bending machine body 1, a positioning structure 8 is provided on the positioning structure 8, and a clamping structure 9 is provided on the positioning structure 8;

[0032] The fixed structure 3 includes a first slider 306, two first sliders 306 are slidably connected to the support plate 2, and the two first sliders 306 are rotatably connected to the second guide shaft 305, the first slider 306 is rotatably connected to the connecting sleeve 307, the connecting sleeve 307 is rotatably connected to the first screw rod 308, the first screw rod 308 is threadedly connected to a slide bar 309, the slide bar 309 is slidably connected to the connecting sleeve 307, and the slide bar 309 is rotatably connected to the pressing roller 310, the bottom end of the connecting sleeve 307 is rotatably connected to the first guide shaft 303, the first guide shaft 303 is arranged at the eccentric position of the connecting sleeve 307, the support plate 2 is slidably connected to the pull plate 301, and the pull plate 301 is provided with two first guide shafts 303. A guide groove 302, two second guide grooves 304 are provided on the pull plate 301, the first guide shaft 303 passes through the first guide groove 302, the second guide shaft 305 passes through the second guide groove 304, one end of the cross section of the pull plate 301 is L-shaped, the top of the first screw rod 308 is fixedly connected to the first knob 311, the resisting structure 4 includes a second screw rod 402, the second screw rod 402 is threadedly connected to the support plate 2, one end of the second screw rod 402 is fixedly connected to the shaft 401, and the other end of the second screw rod 402 is rotatably connected to a stopper 403, and two guide blocks 404 are fixedly connected to the stopper 403, and the guide block 404 is slidably connected to the support plate 2, that is, when it is needed When bending the steel bar, first pull the pull plate 301, and the movement of the pull plate 301 drives the two first guide grooves 302 to move. When the first guide groove 302 moves, the second guide shaft 305 rolls inside the second guide groove 304. When the second guide shaft 305 moves, it will drive the first slider 306 to slide on the support plate 2. The first slider 306 drives the connecting sleeve 307 and the pressure roller 310 to move. When the second guide shaft 305 moves from the inclined position of the second guide groove 304 to the horizontal position of the second guide groove 304, the first slider 306 will not move as the pull plate 301 continues to move. At this time, the first guide shaft 303 moves to the inclined position of the first guide groove 302. The first guide groove 302 rolls inside, and the first guide shaft 303 drives the connecting sleeve 307 to rotate. The rotation of the connecting sleeve 307 drives the sliding rod 309 and the pressure roller 310 to rotate. When the pressure roller 310 rotates ninety degrees, it stops pulling the pulling plate 301. At this time, the two pressure rollers 310 deviate from the top of the guide roller 5. Therefore, it can prevent the pressure roller 310 from resisting the steel bar when placing the steel bar, thereby facilitating the placement of the steel bar. After the steel bar is placed, the steel bar can be pushed. At this time, multiple guide rollers 5 rotate, and the multiple guide rollers 5 can guide the steel bar, thereby facilitating the adjustment of the position of the steel bar. After the position of the steel bar is adjusted, the pulling plate 301 can be pushed. During the pushing process of the pulling plate 301, the two pressure rollers 310 will first rotate toward the top of the steel bar.When the second guide shaft 305 is located in the inclined position of the second guide groove 304, the first slider 306 will drive the connecting sleeve 307 and the pressure roller 310 to move toward the steel bar as the pull plate 301 moves. When the bottom end of the pressure roller 310 contacts the top of the steel bar, the second guide shaft 305 is located in the horizontal position of the bottom end of the second guide groove 304. At this time, the pull plate 301 is continued to be pulled so that the second guide shaft 305 is located in the horizontal position of the end of the second guide groove 304. At this time, the steel bar can be fixed by the two pressure rollers 310, avoiding the need for manual gripping and fixing, thereby improving the safety and convenience of operation. During the bending process, the steel bar can be resisted by the block 403 on one side of the steel bar, so that the bending energy of the steel bar can be reduced. The bending process can be carried out smoothly. When it is necessary to bend steel bars of different diameters, the second screw rod 402 can be rotated by the shaft rod 401. Since the second screw rod 402 and the support plate 2 are threadedly connected, the second screw rod 402 will drive the stopper 403 to move as the second screw rod 402 rotates. The two guide blocks 404 play a guiding role in the movement of the stopper 403. Then, by adjusting the position of the stopper 403, it is convenient to resist steel bars of different diameters. The flexibility of use is good. At the same time, when it is necessary to fix steel bars of different diameters, the first knob 311 is rotated. The rotation of the first knob 311 drives the first screw rod 308 to rotate. The first screw rod 308 rotates the thread to drive the sliding rod 309 to slide on the connecting sleeve 307. The movement of the sliding rod 309 drives the pressing roller 310 to move, so that the initial position of the pressing roller 310 changes. At this time, steel bars of different diameters can be fixed, thereby improving the flexibility of use.

[0033] Specifically, the bending structure 6 includes a turntable 601, which is rotatably connected to the bending machine body 1, and a stop shaft 602 is detachably installed at the rotation center position of the turntable 601. A connecting disk 603 is rotatably connected to the turntable 601, and a plurality of first springs 604 are fixedly connected between the turntable 601 and the connecting disk 603. A second slider 605 is slidably connected to the turntable 601, and a stop shaft 606 is rotatably connected to the second slider 605.

The two clamping blocks The ends of 701 are respectively engaged with the two grooves 703, and the third slider 702 is fixedly connected with a plurality of latch teeth 704. Two second springs 705 are arranged inside the connecting disk 603, and one end of the second spring 705 abuts against the third slider 702, and the other end of the second spring 705 abuts against the connecting disk 603. The cross section of the third slider 702 is L-shaped, the cross section of the block 701 is U-shaped, the cross section of the latch teeth 704 is trapezoidal, the distance between two adjacent latch teeth 704 is equal, and the top of the cross section of the groove 703 is trapezoidal, that is, when the steel bar is fixed, the motor inside the bending machine body 1 can drive the turntable 601 to rotate, and the rotation of the turntable 601 will bring The rotating disk 601 rotates together with the connecting disk 603, and the rotation of the connecting disk 603 drives the second slider 605 and the abutment shaft 606 to move toward the steel bar. When the abutment shaft 606 contacts the steel bar, as the rotating disk 601 continues to rotate, the multiple first springs 604 will shrink. At this time, the multiple first springs 604 can play a buffering role, effectively avoiding the internal motor of the bending machine body 1 from suddenly being subjected to greater resistance during operation due to the collision between the abutment shaft 606 and the steel bar due to the excessive movement of the abutment shaft 606, thereby avoiding damage to the motor and improving the stability of use. As the rotating disk 601 continues to rotate, one side of the rotating disk 601 will conflict with the connecting disk 603. At this time, the rotating disk 601 will drive the connecting disk 603 to move, and the connecting disk 603 drives the abutment shaft 606 to rotate The clamping block 701 can be pulled to bend the steel bars of different diameters. When the end of the clamping block 701 is not engaged with the groove 703, the second slider 605 can be pushed to slide on the connecting plate 603. The second slider 605 will drive the abutment 606 to move during the movement, thereby changing the position of the abutment 606. When the position of the abutment 606 is adjusted, the clamping block 701 can be released. At this time, the end of the clamping block 701 will be engaged with the two grooves 703. At this time, the two third sliders 702 cannot slide on the connecting plate 603. Therefore, the abutment 606 cannot move under the action of the steel bar resistance force, thereby realizing the adjustment of the position of the abutment 606.By adjusting the position of the abutment shaft 606, it is convenient to bend steel bars of different diameters, thereby improving the flexibility of operation.

When the position of the baffle 805 needs to be adjusted, the second knob 804 can be turned, and when the end of the second knob 804 is turned When there is no conflict between the fourth slider 803 and the rotating rod 802, the fourth slider 803 can be pushed to make the fourth slider 803 slide on the rotating rod 802. The movement of the fourth slider 803 will drive the baffle 805 to move together, so that the position of the baffle 805 is changed. After the position adjustment of the baffle 805 is completed, the second knob 804 can be rotated in the opposite direction to make the end of the second knob 804 conflict with the rotating rod 802. At this time, the fourth slider 803 after the adjusted position is fixed. By adjusting the position of the baffle 805, the steel bar can be positioned when the distance between the position of the steel bar bending part and the steel bar end changes, thereby improving the flexibility of use.

[0035] When the present invention is in use, when it is necessary to bend the steel bar, the pulling plate 301 is first pulled, and the movement of the pulling plate 301 drives the two first guide grooves 302 to move. When the first guide groove 302 moves, the second guide shaft 305 rolls inside the second guide groove 304. When the second guide shaft 305 moves, it drives the first slider 306 to slide on the support plate 2. The first slider 306 drives the connecting sleeve 307 and the pressing roller 310 to move. When the second guide shaft 305 moves from the inclined position of the second guide groove 304 to the horizontal position of the second guide groove 304, the first slider 306 will not move as the pulling plate 301 continues to move.

When the steel bar is placed, the steel bar can be pushed. At this time, multiple guide rollers 5 rotate, and the multiple guide rollers 5 can guide the steel bar, thereby facilitating the adjustment of the position of the steel bar. When the position of the steel bar is adjusted, the pulling plate 301 can be pushed.

When it is necessary to bend steel bars of different diameters, the second screw rod 402 can be rotated by the shaft rod 401. Since the second screw rod 402 and the support plate 2 are threadedly connected, the second screw rod 402 will drive the block 403 to move as the second screw rod 402 rotates. The two guide blocks 404 play a guiding role during the movement of the block 403, and then the position of the block 403 can be adjusted to facilitate blocking of steel bars of different diameters, and the flexibility of use is good.At the same time, when it is necessary to fix steel bars of different diameters, the first knob 311 is rotated, and the first knob 311 rotates to drive the first screw rod 308 to rotate, and the first screw rod 308 rotates to drive the sliding rod 309 to slide on the connecting sleeve 307, and the movement of the sliding rod 309 drives the pressing roller 310 to move, so that the initial position of the pressing roller 310 changes, and at this time, steel bars of different diameters can be fixed, thereby improving the flexibility of use;

When the abutment shaft 606 contacts the steel bar, the multiple first springs 604 will shrink as the turntable 601 continues to rotate. At this time, the multiple first springs 604 can play a buffering role, effectively avoiding the motor inside the bending machine body 1 from suddenly being subjected to greater resistance during operation due to the collision between the abutment shaft 606 and the steel bar due to excessive movement, thereby avoiding damage to the motor and improving the stability of use.
