Description

Technical Field

[0001] This utility model relates to a processing device, specifically a steel bar ring bending device. Background Technology

[0002] The mine car pin ring is a key component in the mine car structure. It is used to connect and secure the various parts of the mine car, ensuring the safety and stability of the mine car during transportation.

[0003] Currently, there are some problems in the process of processing mine car pin rings in machine repair shops: First, the processing method is relatively cumbersome, requiring manual movement of steel bars around a self-made mold. This is not only time-consuming and labor-intensive, but also inefficient. Moreover, the product quality is difficult to guarantee, with rings of varying sizes and excessive gaps between rings. The finished products often require secondary processing. Second, the mold occupies a large space, which is not conducive to the efficient use of the site.

[0004] To address the aforementioned issues, there is an urgent need to design and manufacture a labor-saving and practical special processing device for steel bar rings. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a steel bar ring bending device, which facilitates the production of steel bar rings, saves time and labor, improves work efficiency, enhances product quality, and reduces rework rate; it also eliminates the need for mold making and improves site utilization.

[0006] To solve this technical problem, the present invention adopts the following technical solution:

[0007] A rebar ring bending device includes a base, a supporting angle steel fixed to the top of the base, a grooved bearing for limiting the rebar fixed to the left side of the supporting angle steel, a bearing fixed to the rear top of the supporting angle steel, and a supporting frame fixed to the front top of the supporting angle steel; the supporting frame has a through hole in its center, and a semi-circular guide ring fixed to the front side of the supporting frame; the guide ring is fixed to the supporting angle steel, and the left side of the guide ring is spiral-shaped.

[0008] It also includes a rotating shaft that passes laterally through the through hole of the support frame and the inner hole of the bearing. The rotating shaft is slidably connected to the support frame and rotates and is slidably connected to the bearing. The left end of the rotating shaft extends out of the support frame and is fixed with a rocker arm. The top end of the rocker arm is closer to the rotating shaft and the bottom end is farther from the rotating shaft. A steel bar fixing bolt is laterally fixed to the top end of the rocker arm, and the right end of the steel bar fixing bolt extends beyond the right side of the rocker arm.

[0009] Preferably, the bearing is a ball bearing.

[0010] Preferably, an L-shaped steel bar is fixed at the bottom of the guide ring, and the L-shaped steel bar is fixed to the supporting angle steel.

[0011] Preferably, a handle is horizontally fixed to the bottom end of the rocker arm, and the handle is located on the left side of the rocker arm.

[0012] Preferably, the inner hole of the grooved bearing is provided with a grooved fixing bolt in the transverse direction, and the right end of the grooved fixing bolt is fixed to the supporting angle steel.

[0013] The positive effects of this utility model are as follows:

[0014] First, this utility model, by setting up a combination of a rotating shaft and a rocker arm, allows the steel bars to be wound around the rotating shaft by rotating the rocker arm, thereby making the production of steel bar rings more convenient, saving time and effort, and improving work efficiency; moreover, it eliminates the need to make molds, thus improving the utilization rate of the site.

[0015] Secondly, by setting up a support frame, the rotating shaft is forced to move to the left relative to the support frame under the compression of the wound steel bars and the support frame, which ensures close contact between the rings and prevents rework due to excessive gaps between the rings.

[0016] Third, by setting a guide ring, this utility model guides the reinforcing bars to wind around the left side of the guide ring (in a spiral shape) onto the rotating shaft, thereby ensuring that the size and shape of the finished reinforcing bar rings are consistent, further improving product quality. Attached Figure Description

[0017] Figure 1 This is a schematic diagram of the overall structure of this utility model. Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1 As shown, this utility model includes a base 13, with a supporting angle steel 12 fixed to the top of the base 13. A grooved bearing 4 for limiting the position of the reinforcing bar is fixed to the left side of the supporting angle steel 12. The groove of the grooved bearing 4 is U-shaped, and a grooved fixing bolt 3 passes transversely through the inner hole of the grooved bearing 4. The right end of the grooved fixing bolt 3 is fixed to the supporting angle steel 12. A ball bearing 10 is fixed to the rear top of the supporting angle steel 12. By using the ball bearing 10, frictional resistance is reduced, greatly reducing labor intensity. A support frame 8 is fixed to the front top of the supporting angle steel 12, and a through hole 9 is formed in the center of the support frame 8.

[0020] This invention also includes a rotating shaft 11, which transversely passes through the through hole 9 of the support frame 8 and the inner hole of the ball bearing 10. The rotating shaft 11 is slidably connected to the support frame 8, and the rotating shaft 11 and the ball bearing 10 are rotatable and slidably connected. By setting up the support frame 8, this invention forces the rotating shaft 11 to move to the left relative to the support frame 8 under the pressure of the wound steel bars, ensuring tight contact between the rings and preventing rework due to excessive gaps between the rings.

[0021] The left end of the rotating shaft 11 extends out of the support frame 8 and is welded with a rocker arm 2. The top end of the rocker arm 2 is closer to the rotating shaft 11, and the bottom end is farther from the rotating shaft 11. A steel bar fixing bolt 7 is horizontally fixed to the top end of the rocker arm 2, and the right end of the steel bar fixing bolt 7 extends beyond the right side of the rocker arm 2. A crank handle 1 is horizontally fixed to the bottom end of the rocker arm 2, and the crank handle 1 is located on the left side of the rocker arm 2. This utility model, by setting up a combination of rotating shaft 11 and rocker arm 2, allows the steel bar to be wound around the rotating shaft 11 by rotating the rocker arm 2, thereby realizing the convenience of steel bar ring production, saving time and labor, improving work efficiency; and eliminating the need to make molds, thus improving the utilization rate of the site.

[0022] A semi-circular guide ring 6 is welded to the front side of the support frame 8 to guide the reinforcing bars into a ring. An L-shaped reinforcing bar 5 is fixed to the bottom of the guide ring 6, and the L-shaped reinforcing bar 5 is fixed to the supporting angle steel 12. The left side of the guide ring 6 is spiral-shaped; that is, viewed from the left side of the device, the guide ring 6 is located to the right of the through hole 9 (the corresponding position on the left side of the through hole 9 is empty), and the guide ring 6 gradually thickens from the left end in a clockwise direction (tilting forward). This invention, by setting the guide ring 6, guides the reinforcing bars to wind around the rotating shaft 11 along the left side of the guide ring 6 (in a spiral shape), thereby ensuring that the size and shape of the finished reinforcing bar rings are consistent, further improving product quality.

[0023] The steel bar ring bending device described in this utility model is used as follows:

[0024] Pull the rocker arm 2 to the left to create a gap of 2 mm from the left end of the groove fixing bolt 3, thereby pulling the rotating shaft 11 to a suitable position, which facilitates winding the steel bar onto the rotating shaft 11 and also prevents the rocker arm 2 from colliding with the groove fixing bolt 3 during rotation.

[0025] The reinforcing bar is placed at the top of the grooved bearing 4, defining its conveying position. The reinforcing bar is then pulled upwards along the rotating shaft 11, and finally, the end of the reinforcing bar is fixed to the reinforcing bar fixing bolt 7. Holding the crank handle 1, the rocker arm 2 is rotated clockwise, causing the rotating shaft 11 to rotate clockwise. The reinforcing bar first reaches the empty space of the guide ring 6, and then, as the rotating shaft 11 rotates, the right side of the reinforcing bar gradually contacts the guide ring 6, forming a circular reinforcing bar ring. The left side of the newly wound reinforcing bar on the rotating shaft 11 will contact the previously wound reinforcing bar. The new reinforcing bar ring will press against the rocker arm 2, causing the entire rotating shaft 11 and rocker arm 2 to slide to the left relative to the support frame 8 and ball bearing 10, thus achieving continuous spiral winding of the reinforcing bar on the rotating shaft 11 to prepare the reinforcing bar ring.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
