Description

Technical Field

[0002] The Chinese patent application number: CN202320817791.1 proposes a steel bar bending machine, which can realize the simultaneous bending of multiple steel bars by setting multiple placement slots, thereby improving work efficiency and facilitating the measurement of the length of the steel bars to be bent. However, the bending machine still has the following defects:

[0003] The device only clamps the bent end of the steel bar. Generally speaking, the steel bar is long and has a certain weight. Clamping the steel bar only at the bent end cannot maintain the stability of the steel bar. One end of the steel bar will be lifted up and the other end will drag on the ground, making it impossible to perform precise bending.

[0004] Therefore, in order to solve the defect that the bending machine is not stable enough to clamp multiple steel bars, it is necessary to propose a high-efficiency steel bar bending machine. Utility Model Content

[0005] The purpose of the utility model is to provide a high-efficiency steel bar bending machine, which can clamp the unbent part of the steel bar through a movable clamp and a fixed clamp to improve the stability of clamping, and can clamp the end and the bent end of the steel bar through a positioning component to further improve the stability of clamping. The steel bar can be driven to move back and forth through a feeding mechanism, which is convenient for fine-tuning the part of the steel bar to be bent, avoiding manual calibration, and improving work efficiency, and can solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] To solve the technical problem of how to stably clamp multiple steel bars, please refer to Figure 1-Figure 2 and Figure 4 , this embodiment provides the following technical solutions:

[0024] A high-efficiency steel bar bending machine comprises a bending mechanism 1, a feeding mechanism 3 and a positioning component 4.

[0025] A groove 11 is formed on the upper surface of the bending mechanism 1 , a truncated platform 13 is fixed at the center of the groove 11 , and limit blocks 14 are symmetrically mounted on the truncated platform 13 .

[0026] The positioning assembly 4 is installed at the rear end of the bending mechanism 1 and the front end of the feeding mechanism 3. The positioning assembly 4 includes a positioning plate 41 and a bidirectional screw 42 that are symmetrically arranged on the left and right. The positioning plate 41 is threadedly connected to the bidirectional screw 42. One end of the bidirectional screw 42 is fixedly connected to a third motor 43. The upper surfaces of the bending mechanism 1 and the feeding mechanism 3 are both provided with a first slide groove 12, and the positioning plate 41 and the first slide groove 12 form a sliding connection.

[0027] A boss 31 is provided on the feeding mechanism 3, and a cylinder 32 and a fixed clamping plate 33 are fixedly installed on the upper surface of the boss 31. The cylinder 32 is connected to a movable clamping plate 34 through a piston rod. The clamping ends of the fixed clamping plate 33, the movable clamping plate 34 and the positioning plate 41 are all provided with a steel bar groove 5. A slider 341 is provided at the lower end of the movable clamping plate 34, and a second slide groove 311 adapted to the slider 341 is provided on the upper surface of the boss 31.

[0028] Specifically, multiple steel bars are first stacked up and down in a row, and the ends of the steel bars are inserted into the steel bar grooves 5 in the fixed clamps 33 in turn, and then the cylinder 32 is started. The cylinder 32 pushes the movable clamp 34 to move until the end of the steel bar is stably clamped between the fixed clamp 33 and the movable clamp 34, and then the front end of the steel bar is placed between the two limit blocks 14, and then the two third motors 43 are started, so that the third motors 43 drive the bidirectional screw 42 to rotate. Under the limitation of the first slide groove 12, the two positioning plates 41 move toward each other until the end of the steel bar and the bent front end are stably clamped between the two positioning plates 41, thereby further clamping the multiple steel bars and improving the clamping stability.

[0029] To solve the technical problem of how to bend multiple steel bars at the same time, please refer to Figure 3 , this embodiment provides the following technical solutions:

[0030] A gear ring 15 is movably mounted outside the truncated table 13 , a bending shaft 151 is detachably mounted on the gear ring 15 , a gear 16 is meshedly connected to the side end of the gear ring 15 , and a first motor 17 is connected to the lower end of the gear 16 via a transmission shaft.

[0031] Specifically, after multiple steel bars are stably clamped, the first motor 17 is started, the first motor 17 drives the gear 16 to rotate, the gear 16 drives the gear ring 15 meshing therewith to rotate, and the gear ring 15 then drives the bending shaft 151 at its upper end to rotate, thereby bending multiple steel bars simultaneously.

[0032] To solve the technical problem of how to automatically adjust the bending position of the steel bar, please refer to Figure 1 , this embodiment provides the following technical solutions:

[0033] A guide rail 2 is provided at the side end of the bending mechanism 1, a screw rod 21 is movably installed in the guide rail 2, one end of the screw rod 21 is fixedly connected to a second motor 23, the feeding mechanism 3 is threadedly connected to the screw rod 21, and sliding rods 22 are symmetrically provided at the left and right ends of the screw rod 21, and the feeding mechanism 3 is slidably connected to the sliding rod 22.

[0034] Specifically, when the bending position needs to be adjusted, the positioning plates 41 in the front and rear positioning assemblies 4 are first loosened. At this time, the fixed clamping plate 33 and the movable clamping plate 34 stably clamp the steel bars. The second motor 23 is started, and the second motor 23 drives the screw rod 21 to rotate. Under the limit of the slide bar 22, the feeding mechanism 3 can move forward and backward, and drive the steel bars clamped at its upper end to move forward and backward, so as to fine-tune the position where the steel bars need to be bent. After the adjustment is completed, the positioning plate 41 is used to stably clamp the end and the bending end of the steel bars.

[0035] Working principle: When using this high-efficiency steel bar bending machine, first stack multiple steel bars up and down into a row, then insert the end of the steel bar into the steel bar groove 5 in the fixed clamp 33, and then start the cylinder 32. The cylinder 32 pushes the movable clamp 34 to move until the movable clamp 34 and the fixed clamp 33 stably clamp the end of the steel bar, and then place the front end of the steel bar between the two limit blocks 14, and then start the second motor 23 to drive the feeding mechanism 3 to drive the steel bar to move back and forth, and fine-tune the bending position of the steel bar. After the adjustment is completed, turn off the second motor 23, and then start the third motor 43, so that the two positioning plates 41 can stably clamp the steel bar, and finally start the first motor 17 to drive the bending shaft 151 to rotate to bend multiple steel bars at the same time.
