Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel bar processing equipment technology, specifically a steel bar bending machine with an angle adjustment mechanism. Background Technology
[0002] Rebar bending machines can process various types of rebar, such as ordinary carbon steel and threaded steel, into specific shapes required for engineering projects. In traditional rebar bending operations, manual rebar bending machines were widely used. However, when using a manual rebar bending machine, the bending angle depends on the operator's personal experience. Because different operators have varying levels of experience, and it is difficult to achieve completely consistent force and technique control during operation, deviations in the bending angle occur, resulting in limitations.
[0003] The reason for this problem is that when performing bending operations, operators find it difficult to accurately perceive and reproduce the force and rotation amplitude applied each time they bend. This makes it impossible to effectively guarantee the consistency of the bending angle. In addition, manual rebar bending machines themselves usually do not have precise angle measurement and adjustment devices. Operators can only determine the bending angle by visual observation and experience. This method is easily affected by external environmental factors in actual operation, which further increases the probability of angle deviation. Utility Model Content

[0029] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0030] This utility model discloses a rebar bending machine with an angle adjustment mechanism, according to the attached...

[0033] In this embodiment, the operator places the reinforcing bar on the bending machine 1 and bends it by rotating the drum 12, utilizing the relative motion between the drum 12 and the machine body 11. The insert rod 13 is inserted into the insertion hole on the drum 12, causing the drum 12 to rotate. The clamping block 14 bends the reinforcing bar during the rotation of the drum 12. The guide block 15 guides the reinforcing bar to be placed correctly, and the elastic clamping block 16 can store the insert rod 13 when not in use, facilitating operation.
[0034] According to the appendix Figure 1 , 3 As shown in Figure 4, further, it includes a bending machine 1, and an angle adjustment unit 2 is provided on one side of the bending machine 1. The angle adjustment unit 2 includes a fixing hole 21, a spring clip 22 and a stop bar 23.
[0035] A fixing hole 21 is provided on one side of the bending machine 1. The fixing hole 21 includes a 90° hole 211, a 135° hole 212 and a 180° hole 213. A spring clip 22 is rotatably connected to one side of the machine body 1. The spring clip 22 is movably engaged with the fixing hole 21. A stop bar 23 is provided on one side of the bending machine 1. The stop bar 23 abuts against the spring clip 22. The stop bar 23 is used to block the rotation angle of the bending machine 1.
[0036] The spring clip 22 includes a slide rod 221 and an anti-detachment plate 222; the slide rod 221 is slidably connected inside the rotating cylinder 12; the anti-detachment plate 222 is fixedly assembled to the end of the slide rod 221, and the end of the anti-detachment plate 222 abuts against the inner wall of the rotating cylinder 12. The spring clip 22 also includes a rotating plate 223 and ball bearings 224; the rotating plate 223 is sleeved on the outer surface of the slide rod 221; the ball bearings 224 are disposed on one side of the rotating plate 223, and the ball bearings 224 are arranged in a ring array, abutting against the inner wall of the rotating cylinder 12. The spring clip 22 also includes a spring 225, a connecting rod 226, and a stop 227; the spring 225 is wound around the outer surface of the slide rod 221, one end of the spring 225 is fixedly assembled with the rotating plate 223, and the other end of the spring 225 is fixedly assembled with the anti-detachment plate 222; the connecting rod 226 is fixedly assembled at the end of the slide rod 221, and the connecting rod 226 is movably engaged with the fixing hole 21; the stop 227 is fixedly assembled on one side of the connecting rod 226, and the stop 227 abuts against the stop rod 23.
[0037] In this embodiment, the slide rod 221 slides inside the rotating cylinder 12, and the anti-detachment plate 222 effectively prevents the slide rod 221 from coming off the rotating cylinder 12, ensuring the stability of the structure. The rotating plate 223 is sleeved on the outer surface of the slide rod 221, and the ball bearing 224 on one side abuts against the inner wall of the rotating cylinder 12, which can reduce the friction when the rotating plate 223 rotates, making the rotation of the spring clip 22 smoother. The spring 225 is wound around the outer surface of the slide rod 221, with one end connected to the rotating plate 223 and the other end connected to the anti-detachment plate 222. Under the elastic action of the spring 225, it can drive the slide rod 221 and related components to perform reset and locking actions, ensuring that the connecting rod 226 is stably locked with the fixing hole 21. The stop block 227 moves with the connecting rod 226, providing a blocking effect for angle control.
[0038] Working principle: This device achieves precise control through the angle adjustment unit 2. When it is necessary to bend the rebar to a specific angle of 90°, 135°, or 180°, the connecting rod 226 of the spring clip 22 is aligned with the corresponding fixing hole 21, namely the 90° hole 211, the 135° hole 212, or the 180° hole 213. Under the action of the spring 225, the connecting rod 226 is engaged in the corresponding fixing hole. Then, the rotating drum 12 is rotated to bend the rebar. During the rotation of the rotating drum 12, the spring clip 22 rotates accordingly. When the stop block 227 abuts against the stop rod 23, the rotating drum 12 can no longer rotate. At this time, the bending angle of the rebar reaches the set value, thus achieving precise adjustment of the bending angle of the rebar. It should be noted that 90°, 135°, or 180° are the more commonly used bending angles for rebar bending.
