Description

Technical Field

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

[0002] When constructing load-bearing walls, concrete and reinforcing cages are poured. During the pouring process, the reinforcing bars need to be bent to increase the interlocking force between the bars and the concrete. Currently used rebar bending machines have limited functionality; they cannot position the rebars during bending, nor can they straighten them after bending.

[0003] A steel bar bending machine for construction, according to patent application number CN201720682560.9, includes a machine body and a machine head. The machine body is equipped with a handle and a transmission screw. The handle is welded to the side of the machine body. The transmission screw is threaded to the front and rear ends of the machine body. The transmission screw has a force-applying rod and a concave retainer for transmission. The force-applying rod passes through the rear end of the transmission screw. The concave retainer is welded to the front end of the transmission screw via a rotating shaft. The front end of the concave retainer has a tension groove, and the rear end has a push groove. The machine head is welded to both sides of the front end of the machine body. The front end of the machine head has a groove, and a rear pulley is welded to the rear end of the groove. A front pulley is bolted to the front end of the groove, and the front pulley is connected to the bolt rotating shaft. This utility model has a simple structure and can not only conveniently and quickly bend steel bars, but also straighten bent steel bars.

[0004] The patent application still has shortcomings. It requires manual rotation of the lever for mechanical bending, and each steel bar needs to be bent multiple times to achieve the desired shape. This results in a large workload for workers and low bending efficiency.

[0005] Therefore, a steel bar bending machine is needed to solve this problem. Utility Model Content

[0015] Beneficial effects

[0016] This invention allows the reinforcing bar to be placed on a rotating shaft between clamping wheels. The clamping wheels can fix and hold the reinforcing bar, and the rotating shaft can rotate in the bushing. The clamping wheels can also rotate around the fitting shaft, thereby reducing the resistance when bending the reinforcing bar and greatly improving the bending efficiency.

[0017] This invention uses a telescopic mechanism to move a bending column downwards, thereby pressing down on the reinforcing bars to achieve bending.

[0018] This invention uses a spiral motor to drive a spiral column to rotate.

[0019] This invention utilizes a hydraulic press to move a connecting rod upwards, which in turn uses the upward rod to drive a recovery groove to apply pressure and restore the bent node. Simultaneously, a servo motor drives a gear to rotate, which in turn drives a sawtooth rod that is engaged with it to move downwards. The sawtooth rod then drives a downward recovery rod to slide down through a sliding through hole. A lateral limiting rod engaged in a limiting groove can laterally limit the recovery rod. The downward recovery rod drives the recovery groove to straighten the bent rebar, greatly improving the functionality of the device. Attached Figure Description

[0030] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:

[0031] Example 1

[0032] Please see Figures 1 to 4 Example 1 describes a rebar bending machine, comprising an operating platform 1 and an operating plate 2 mounted on the operating platform 1. Rebar fixing components 3 are provided between the operating plates 2, and a descending rebar bending component 4 is provided between the rebar fixing components 3. The operating plate 2 has several sliding through holes 21, and the operating platform 1 has several lifting holes 11. The rebar fixing component 3 includes two bushings 31, which are mounted on one side of the operating plate 2. A rotating shaft 32 is fitted into each bushing 31. Several springs 33 are provided on one side of each bushing 31. One end of each spring 33 is connected to a fixing plate 331, and both ends of the fixing plate 331 are connected to intermediate plates 341. A fitting shaft 34 is installed between the intermediate plates 341, and a clamping wheel 35 is provided on the fitting shaft 34. The descending rebar bending component 4 includes a bending column 41, which is connected to a column shaft 42. The column shaft 42 is connected to a sliding frame 43, which fits into the sliding through holes 21. Several telescopic mechanisms 44 are connected below the sliding frame 43.

[0033] In this embodiment, the reinforcing bar is placed on the rotating shaft 32 between the clamping wheels 35. The spring 33 provides a spring force to the fixing plate 331. The clamping wheel 35 is fixedly clamped by the interlocking shaft 34. When the reinforcing bar is bent, the clamping contact point of the reinforcing bar will move, which will drive the rotating shaft 32 to rotate in the bushing 31. The clamping wheel 35 can also rotate around the interlocking shaft 34, thereby reducing the resistance when bending the reinforcing bar and greatly improving the bending efficiency. When bending, the telescopic machine 44 drives the sliding frame 43 to slide downward in the sliding through hole 21. The sliding frame 43 drives the column shaft 42 to descend. The column shaft 42 drives the bending column 41 to press down on the reinforcing bar to achieve downward bending of the reinforcing bar.

[0034] Example 2

[0035] Please see Figures 5 to 7 Example 2 further illustrates Example 1. Below the downward bending rebar assembly 4, an upward recovery assembly 5 is provided. Between the downward bending rebar assemblies 4, a downward recovery assembly 6 is provided. Below the downward recovery assembly 6, an upward bending rebar assembly 7 is provided. The upward bending rebar assembly 7 includes a sliding rod 71, one end of which is connected to a bending column 41, and the other end has a spiral hole 72. The spiral hole 72 is fitted with a spiral column 73, which is connected to a spiral motor 74. The upward recovery assembly 5 includes a recovery groove 51. 1. Connect the upward rod 52, which is fitted into the lifting hole 11. A connecting rod 521 is installed between the upward rods 52. The connecting rod 521 is connected to the hydraulic press 53. The downward recovery assembly 6 includes a downward recovery rod 61. One end of the downward recovery rod 61 is connected to the recovery groove 51, and the other end is connected to the sawtooth rod 62. The downward recovery rod 61 is provided with a lateral limiting rod 63, which is fitted into the limiting groove 64. The limiting groove 64 is located on the inner side of the sliding through hole 21. The sawtooth rod 62 is fitted into the gear 621, which is mounted on the servo motor 65.

[0036] In this embodiment, the spiral motor 74 can drive the spiral column 73 to rotate. The spiral column 73 acts on the spiral hole 72 and uses the spiral force to drive the sliding rod 71 to bend the steel bar by moving it upward in the sliding through hole 21. This allows multiple steel bars to bend simultaneously, greatly improving the bending efficiency of the steel bars. The hydraulic press 53 can drive the connecting rod 521 to move upward, and then use the upward rod 52 to drive the recovery groove 51 to apply pressure to restore the bent node. At the same time, the servo motor 65 can drive the gear 621 to rotate. The gear 621 drives the sawtooth rod 62, which is engaged with it, to move downward. The sawtooth rod 62 drives the downward recovery rod 61 to slide down in the sliding through hole 21. The lateral limiting rod 63 is engaged in the limiting groove 64 to laterally limit the recovery rod 61. The downward recovery rod 61 drives the recovery groove 51 to straighten the bent steel bar, greatly improving the functionality of the device.

[0037] In practical applications, the reinforcing bar is first placed on the rotating shaft 32 between the clamping wheels 35. The spring 33 provides a spring force to the fixing plate 331. The fixing plate 331 drives the fitting shaft 34, which in turn drives the clamping wheels 35 to fix and clamp the reinforcing bar. When the reinforcing bar is bent, the clamping contact point of the reinforcing bar will move, which will drive the rotating shaft 32 to rotate in the bushing 31. The clamping wheels 35 can also rotate around the fitting shaft 34, thereby reducing the resistance when bending the reinforcing bar and greatly improving the bending efficiency. The telescopic machine 44 and the screw motor 74 are started. The telescopic machine 44 drives the sliding frame 43 to slide downward in the sliding through hole 21. The sliding frame 43 drives the column shaft 42 to descend. The column shaft 42 drives the bending column 41 to press down on the reinforcing bar to achieve bending. The screw motor 74 drives the screw column 73 to rotate. The screw column 73 acts on the screw hole 7. 2. The spiral force drives the sliding rod 71 to bend the reinforcing bar by moving it upward in the sliding through hole 21, thereby achieving simultaneous bending of multiple points of the reinforcing bar and greatly improving the bending efficiency of the reinforcing bar. When it is necessary to straighten the reinforcing bar, the hydraulic press 53 is started. The hydraulic press 53 drives the connecting rod 521 to move upward, and then the upward rod 52 drives the recovery groove 51 to apply pressure to the bent node to restore it. At the same time, the servo motor 65 is started, and the servo motor 65 drives the gear 621 to rotate. The gear 621 drives the sawtooth rod 62, which is engaged with it, to move downward. The sawtooth rod 62 drives the downward recovery rod 61 to slide down in the sliding through hole 21. The lateral limit rod 63 is engaged in the limit groove 64 to laterally limit the recovery rod 61. The downward recovery rod 61 drives the recovery groove 51 to straighten the bent reinforcing bar, which greatly improves the functionality of the device.
