Description

Technical Field

[0001] The utility model relates to the technical field of steel bar processing equipment, and more specifically, to a positioning device for steel bar cutting. Background Technique

[0002] When processing steel bars, a long steel bar generally needs to be cut into shorter steel bars multiple times. In some small processing plants, a positioning plate is installed behind the cutting machine, which can quickly and accurately cut the steel bars.

[0003] However, when cutting steel bars, since the long steel bar is not necessarily a little more than an integer multiple of the short steel bar, when cutting into short steel bars, there is often a long tail material left in the end. If these tail materials are directly discarded, it will cause waste. If they are placed on one side first and waiting for subsequent use, it will affect the work efficiency.

[0004] It should be noted that the above content belongs to the technical cognition scope of the inventor and does not necessarily constitute the prior art. Content of the Utility Model

[0005] The purpose of the utility model is to solve the above problems and design a positioning device for steel bar cutting.

[0006] To achieve the above purpose, the technical solution of the utility model is a positioning device for steel bar cutting, including a workbench, a plurality of rotating rollers are installed at the upper end of the workbench, a positioning mechanism is arranged on the workbench, and a guiding mechanism is installed on the workbench;

[0007] The positioning mechanism includes a fixed table installed on the workbench by bolt connection, a rotating frame is installed at the front end of the fixed table, a first limiting plate is installed on the rotating frame, a telescopic frame is installed at the rear end of the fixed table, and a second limiting plate is installed on the telescopic frame;

[0008] The guiding mechanism includes a plurality of inclined collecting rods detachably installed on both side surfaces of the workbench, an intercepting rod is installed at the end of the inclined collecting rod, rotatable turning frames are installed on both side surfaces of the workbench, a plurality of limiting rollers are installed on the turning frames, and the rotating rollers are tapered with a large middle and small ends.

[0009] Furthermore, the rotating frame includes a servo motor installed on the upper surface of the fixed table, and the first limiting plate is installed at the rotating end of the servo motor.

[0010] Further, the flipping frame includes rotating shafts located on both sides of the workbench. Rolling bearings are installed at both ends of the rotating shafts. The rolling bearings are installed on one side surface of the workbench through support rods. The rotating shafts on both sides of the workbench are connected through a connecting mechanism.

Detailed implementation mode

[0019] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model. In addition, in the description of the present utility model, the meaning of "a plurality of" is two or more unless otherwise specifically defined.

[0021] The present utility model provides a positioning device for steel bar cutting as Figures 1-4 shown, which includes a workbench 1. A plurality of rotating rollers 2 are installed at the upper end of the workbench 1. A positioning mechanism is provided on the workbench 1, and a guiding mechanism is installed on the workbench 1. The positioning mechanism includes a fixed table 3 connected and installed on the workbench 1 by bolts. A rotating frame 4 is installed at the front end of the fixed table 3, a first limiting plate 5 is installed on the rotating frame 4, a telescopic frame 6 is installed at the rear end of the fixed table 3, and a second limiting plate 7 is installed on the telescopic frame 6. The guiding mechanism includes a plurality of inclined collecting rods 8 detachably installed on the two side surfaces of the workbench 1. An intercepting rod 9 is installed at the end of the inclined collecting rod 8. Rotatable flipping frames 10 are installed on the two side surfaces of the workbench 1, and a plurality of limiting rollers 11 are installed on the flipping frames 10. The rotating roller 2 is a conical shape with a larger middle and smaller ends.

[0022] The process of steel bar positioning and cutting of this device is as follows: Under normal conditions, if the rotating frame 4 drives the first limiting plate 5 to rotate and makes the first limiting plate 5 rotate to the lower side, the position of the second limiting plate 7 is adjusted through the telescopic frame 6. The limiting roller 11 on one side of the workbench 1 is rotated to the upper side through the flipping frame 10, and the limiting roller 11 on the other side of the workbench 1 is rotated to the lower side. One end of the steel bar is passed through the cutting machine and abutted against the first limiting plate 5, and then the steel bar is cut. The cut steel bar can fall on the rotating roller 2. Since the limiting roller 11 limits one side of the steel bar, the cut steel bar can roll to the other side under the action of the inclined surface of the rotating roller 2, and the steel bar is collected through the inclined collecting rod 8 and intercepted by the intercepting rod 9, so as to facilitate the cutting of the steel bar. After cutting several times, the rotating frame 4 drives the first limiting plate 5 to rotate to the upper side, then one end of the steel bar is abutted against the second limiting plate 7, the limiting roller 11 originally located on the upper side is rotated to the lower side through the flipping frame 10, and the limiting roller 11 originally located on the lower side is rotated to the upper side, and then the steel bar is cut again. The cut steel bar can roll in a direction different from that of the first steel pipe under the action of the inclined surface of the rotating roller 2 and is collected by the inclined collecting rod 8 and the intercepting rod 9. Since the lengths of the two cut steel bars are different, different quantity combinations can be used to shorten the tail material and avoid waste.

[0023] Refer to the attached drawings of the specification Figure 1 , the attached drawings of the specification Figure 2 and the attached drawings of the specification Figure 4 , the rotating frame 4 includes a servo motor 12 installed on the upper surface of the fixed table 3. The first limiting plate 5 is installed at the rotating end of the servo motor 12. By driving the first limiting plate 5 to rotate through the servo motor 12, the first limiting plate 5 can be quickly and accurately moved to the specified position.

[0024] Refer to the attached drawings of the specification Figure 1 , the attached drawings of the specification Figure 2 and the attached drawings of the specification Figure 4 , the flipping frame 10 includes rotating shafts 13 located on both sides of the workbench 1. Rolling bearings 14 are installed at both ends of the rotating shafts 13. The rolling bearings 14 are installed on one side surface of the workbench 1 through support rods 15. The rotating shafts 13 on both sides of the workbench 1 are connected through a connecting mechanism. A first sprocket 16 is installed at the rotating end of the servo motor 12. The first sprocket 16 is connected to a second sprocket 18 through a first chain 17. The second sprocket 18 is sleeved on one rotating shaft 13. The second sprocket 18 is fixedly installed on this rotating shaft 13 through bolt connection. The limiting roller 11 is detachably installed on the rotating shaft 13;

[0025] The process of the flipping frame 10 driving the limiting roller 11 to rotate is as follows: According to the length of the cut reinforcing bar, first move the second sprocket 18 to the specified position and fix the second sprocket 18 on the rotating shaft 13 by bolt connection. If the limiting roller 11 and the inclined collecting rod 8 block the movement of the second sprocket 18, the limiting roller 11 and the inclined collecting rod 8 can be removed first, then the second sprocket 18 can be moved, and then the limiting roller 11 and the inclined collecting rod 8 can be installed. When the limiting roller 11 needs to rotate, the servo motor 12 drives the first sprocket 16 to rotate. The first sprocket 16 rotates with the second sprocket 18 through the first chain 17. Furthermore, the second sprocket 18 and a rotating shaft 13 can be rotated. The two rotating shafts 13 are connected through a connecting mechanism. Furthermore, the two rotating shafts 13 can rotate synchronously. Furthermore, the limiting rollers 11 on the two rotating shafts 13 are one above and the other below, which is convenient for guiding the cutting of the reinforcing bar.

[0026] Refer to the accompanying drawings of the specification and the specification appendix Figure 3 The connecting mechanism includes a third sprocket 19 installed at one end of the rotating shaft 13. The third sprockets 19 on the two rotating shafts 13 are connected by a second chain 20. A square hole 21 for avoiding the second chain 20 is opened on the workbench 1. When one rotating shaft 13 rotates, it can drive one third sprocket 19 to rotate. The two third sprockets 19 are connected by a second chain 20. Furthermore, it is convenient for the two rotating shafts 13 to rotate synchronously.

[0027] Refer to the accompanying drawings of the specification and the specification appendix Figure 2 The telescopic frame 6 includes a moving rod 22 located at the rear side of the fixed table 3. A guiding hole 23 is opened at the rear side of the fixed table 3. One end of the moving rod 22 extends into the guiding hole 23. The second limiting plate 7 is installed at the lower end of the moving rod 22. A threaded hole 24 is opened on one side of the guiding hole 23. The threaded hole 24 is connected with a positioning screw rod 25 by bolt connection;

[0028] The process of the telescopic frame 6 adjusting the position of the second limiting plate 7 is as follows: Rotate the positioning screw rod 25. Through the threaded connection between the positioning screw rod 25 and the threaded hole 24, the positioning screw rod 25 can move upward and loosen the moving rod 22. The staff adjusts the position of the moving rod 22. After the adjustment is completed, reverse the positioning screw rod 25. Through the threaded connection between the positioning screw rod 25 and the threaded hole 24, the positioning screw rod 25 can move downward and fix the moving rod 22. Then, the movement of the second limiting plate 7 can be prevented, which is convenient for positioning the reinforcing bar.
