Description

Technical Field

[0001] This utility model relates to the field of construction technology, and in particular to a steel bar bending device for building construction. Background Technology

[0002] A rebar bending device for construction is a specialized piece of equipment used to bend rebar into specific angles according to design requirements. It mainly consists of a worktable, servo motor, transmission system, turntable, and fixed cylinder. Driven mechanically or hydraulically, it precisely controls the bending angle and curvature to ensure the rebar conforms to construction specifications. This device is efficient and labor-saving, capable of handling rebar of different diameters, and widely used in the processing of beams, columns, slabs, and other components, improving project quality and efficiency while reducing human error and material waste.

[0003] CN221833209U discloses a steel bar bending device for building construction, including a machine base, a bending mechanism, a limiting mechanism, and a motor. The motor is installed and fixed on the inner bottom of the machine base, and the output end of the motor drives and connects to the bending mechanism. The upper end of the bending mechanism extends to the top of the machine base. The lower end of the limiting mechanism is installed and fixed on the inner wall of the machine base, and the upper end of the limiting mechanism extends to the top of the machine base.

[0004] This product, through the coordinated design of bending and limiting mechanisms, allows construction workers to easily and quickly bend multiple thinner steel bars. It also facilitates the adjustment and replacement of the steel bar placement seat and bending cylinder to accommodate the steel bars to be bent, thus improving the convenience of steel bar bending. However, this product is only suitable for bending thinner steel bars, and it is difficult to adjust and complete the bending work for other specifications of steel bars. It lacks versatility, affects production efficiency, and thus reduces the practicality of the product.

[0005] Therefore, those skilled in the art have provided a steel bar bending device for building construction to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a steel bar bending device for building construction. The device rotates a worm gear on a support plate by shaking a handle. The rotation of the worm gear drives a worm wheel, which in turn rotates a threaded rod inside a sliding frame. The slider then slides back and forth within the first and second sliding grooves. During this sliding, the iron shaft and the abutment plate mounted on it also slide and change position. If the orientation of the abutment plate needs to be changed at a designated position, the pin inserted into the through groove and the insertion hole can be pulled out. Then, the iron shaft is rotated to turn the abutment plate, and the pin is reinserted into another insertion hole on the slider. This flexible adjustment of the abutment plate position allows for changing the bending fulcrum position, thus adapting to the processing requirements of steel bars of different diameters, improving versatility, and ultimately enhancing the product's practicality.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A rebar bending device for building construction includes an adjustment mechanism, a convenient replacement mechanism, a controller, an overlap frame, and a door. The adjustment mechanism includes a workbench, with a sliding frame on one side of the upper interior of the workbench. A first sliding groove is formed on one end face of the sliding frame, and threaded rods are rotatably connected to both ends of the first sliding groove. A worm gear is fixedly connected to one end of the threaded rod, and a worm is meshed with one side of the outer wall of the worm gear. A handle is fixedly connected to one end of the worm. A support plate is fixedly connected to one end of the sliding frame. A second sliding groove is formed on the upper end face of the sliding frame, and a slider is slidably connected to one side of the outer wall of the second and first sliding grooves. Insertion holes are formed at both ends of the upper end face of the slider. A rotating shaft is rotatably connected to the middle of the upper end face of the slider. An iron shaft is fixedly connected to the upper end of the rotating shaft, and an abutment plate is fixedly connected to one end of the iron shaft. A through groove is formed on one end of the outer wall of the iron shaft, and a pin is fitted in the middle of the through groove.

[0009] Through the above technical solution, the device rotates the worm gear on the support plate by shaking the handle. The rotation of the worm gear drives the worm wheel to rotate, which in turn causes the threaded rod in the sliding frame to rotate. Thus, the slider slides back and forth under the constraint of the first and second sliding grooves. During the sliding, the iron shaft and the abutment plate mounted on it also slide and change position. If it is necessary to change the orientation of the abutment plate when it reaches the designated position, the pin inserted in the through groove and the insertion hole can be pulled out, and then the iron shaft can be rotated to turn the abutment plate. Then the pin can be inserted again into another insertion hole of the slider. The flexible adjustment of the position of the abutment plate can change the position of the bending fulcrum, thereby adapting to the processing requirements of steel bars of different diameters, improving versatility, and thus enhancing the practicality of the product.

[0010] Furthermore, the convenient replacement mechanism includes a servo motor, an eccentric wheel fixedly connected to the output end of the servo motor, a turntable fixedly connected to the upper end of the eccentric wheel, a bending cylinder slidably connected to one end of one side face of the turntable, a connecting rod fixedly connected to the middle of one end of the worktable, a plug-in post fixedly connected to one end of the connecting rod, hook blocks fixedly connected to both sides of the upper end of the outer wall of the plug-in post, a threaded rod fixedly connected to the upper end of the plug-in post, a fixing cylinder sleeved on the lower end of the outer wall of the threaded rod, a locking block sleeved on the middle of the outer wall of the threaded rod, a spring fixedly connected to the upper end of the locking block, and an adjusting ring slidably connected to the upper end of the spring.

[0011] Through the above technical solution, the device uses a controller to control a servo motor to drive the turntable to rotate, placing the reinforcing bar on the turntable. The support of the fixed cylinder and the output of the bending cylinder allow the reinforcing bar to be bent smoothly. When installing the fixed cylinder, it can be inserted into the plug-in column until it is locked in place with the hook block. Then, the locking block is put into the threaded bar, and then the adjusting ring is twisted to make its spiral move down and compress the spring, so that the locking block is close to and locked with the upper end of the exposed hook block, thus completing the installation of the fixed cylinder. This allows the easily worn fixed cylinder to be easily replaced, improving the practicality of the product.

[0012] Furthermore, the upper ends of the slider are slidably connected to the second groove on both sides, and the lower end of the slider is fitted with a threaded rod;

[0013] Through the above technical solution, this setting enables the slider to use the threaded rod as the output source and slide stably.

[0014] Furthermore, a worm gear is rotatably connected to the lower end face of the support plate, and one end of the worm wheel is rotatably connected to the middle of one side end face of the support plate;

[0015] Through the above technical solution, this setting enables both the worm and the worm wheel to have a stable pivot point.

[0016] Furthermore, a controller is provided on one side of the upper end face of the adjustment mechanism, a connecting frame is fixedly connected to the middle of the upper end face of the adjustment mechanism, and a box door is rotatably connected to the middle of the middle of the one side end face of the adjustment mechanism.

[0017] Through the above technical solution, this setup enables the controller to control the normal operation of the device, the scaffolding to assist workers in fixing the reinforcing bars, and the box door for routine maintenance.

[0018] Furthermore, one side of the outer wall of the two hook blocks forms an engaging connection with the upper inner end of the fixing cylinder;

[0019] Through the above technical solution, this setting allows the fixing cylinder to be initially fixed in the center of the turntable.

[0020] Furthermore, the upper end of the outer wall of the threaded rod is provided with threads, and an adjusting ring is threadedly connected to the upper end of the outer wall of the threaded rod;

[0021] Through the above technical solution, this setting enables the adjusting ring to be threaded onto the threaded rod, thereby depressing the spring when the screw moves downward.

[0022] Furthermore, both ends of the locking block are engaged with the upper end of the hook block;

[0023] Through the above technical solution, this setting enables the locking block to fix the fixing cylinder to the plug-in post to prevent it from falling off.

[0024] This utility model has the following beneficial effects:

[0025] 1. This utility model proposes a steel bar bending device for building construction. The device rotates the worm gear on the support plate by shaking the handle. The rotation of the worm gear drives the worm wheel to rotate, which in turn causes the threaded rod in the sliding frame to rotate. As a result, the slider slides back and forth under the constraint of the first and second sliding grooves. During the sliding, the iron shaft and the abutment plate mounted on it also slide and change position. If it is necessary to change the orientation of the abutment plate when it reaches the designated position, the pin inserted in the through groove and the insertion hole can be pulled out. Then, the iron shaft is rotated to turn the abutment plate. The pin is then inserted again into another insertion hole of the slider. The flexible adjustment of the position of the abutment plate can change the position of the bending fulcrum, thereby adapting to the processing requirements of steel bars of different diameters, improving versatility, and thus enhancing the practicality of the product.

[0026] 2. This utility model proposes a steel bar bending device for building construction. The device uses a controller to control a servo motor to drive a turntable to rotate. The steel bar is placed on the turntable, and the support of the fixed cylinder and the output of the bending cylinder make the steel bar bend smoothly. When installing the fixed cylinder, it can be inserted into the plug-in column until it is locked with the hook block. Then, the locking block is put into the threaded bar, and then the adjusting ring is twisted to make its spiral move down and squeeze the spring, so that the locking block is close to the upper end of the exposed hook block and locks with it, thus completing the installation of the fixed cylinder. This allows the easily worn fixed cylinder to be easily replaced, improving the practicality of the product. Attached Figure Description

Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Reference Figure 1-3 One specific embodiment provided by this utility model:

[0037] A rebar bending device for building construction includes an adjusting mechanism 1, a convenient replacement mechanism 2, a controller 3, an overlapping frame 4, and a door 5.

A through groove 115 is provided on one end of the outer wall of the iron shaft 113. A pin 116 is fitted inside the center of the through groove 115. The device rotates by shaking the handle 107, causing the worm gear 106 on the support plate 108 to rotate. The rotation of the worm gear 106 drives the worm wheel 105 to rotate, which in turn causes the threaded rod 104 inside the sliding frame 102 to rotate. Thus, the slider 110 reciprocates under the constraint of the first sliding groove 103 and the second sliding groove 109. During sliding, the iron shaft mounted on it... The position of 113 and the abutment plate 114 also slides and changes accordingly. If it is necessary to change the orientation of the abutment plate 114 when it slides to the designated position, the pin 116 inserted in the through groove 115 and the insertion hole 111 can be pulled out. Then, the iron shaft 113 is rotated to make the abutment plate 114 turn. Then, the pin 116 is inserted again into the other insertion hole 111 of the slider 110. The flexible adjustment of the position of the abutment plate 114 can change the position of the bending fulcrum, thereby adapting to the processing requirements of steel bars of different diameters, improving versatility, and thus enhancing the practicality of the product.

The steel bar is smoothly bent by the support of the fixed cylinder 209 and the output of the bending cylinder 204. When installing the fixed cylinder 209, it can be inserted into the plug post 206 until it is locked with the hook block 207. Then, the locking block 210 is put into the threaded bar 208. Then, the adjusting ring 212 is twisted to make it spiral down and squeeze the spring 211, so that the locking block 210 is close to the upper end of the exposed hook block 207 and locked, thus completing the installation of the fixed cylinder 209.

[0045] Working principle: The device rotates the worm gear 106 on the support plate 108 by shaking the handle 107. The rotation of the worm gear 106 drives the worm wheel 105 to rotate, which in turn causes the threaded rod 104 in the sliding frame 102 to rotate.

During the sliding, the iron shaft 113 and the abutment plate 114 mounted on it also slide and change position. If it is necessary to change the orientation of the abutment plate 114 when it slides to a designated position, the pin 116 inserted in the through groove 115 and the insertion hole 111 can be pulled out.
