Description

Technical Field

[0001] This utility model relates to the field of bar processing technology, and in particular to a stainless steel bar straightening and length-fixing cutting device. Background Technology

[0002] Stainless steel bars are long strip-shaped metal materials made from stainless steel through specific processing techniques. Stainless steel bars refer to solid metal materials with regular cross-sections such as circles, squares, and hexagons, and whose length is much greater than the cross-sectional dimensions. Their material is stainless steel.

[0003] In existing technologies, the straightening and cutting of stainless steel bars are usually done in two separate work areas. Operators need to move the straightened stainless steel bars to the cutting area for cutting, which is time-consuming. When straightening stainless steel bars, if the cross-section is square, placing the square stainless steel bar in the straightening area is more stable, making it easier to flip the square stainless steel bar for straightening. However, when straightening stainless steel bars with a circular cross-section, the circular cross-section is prone to rolling, and the straightening area's function of limiting and fixing the stainless steel bar is relatively weak. It is necessary to manually hold the circular stainless steel bar. However, when manually holding the stainless steel bar, it is easy to lose stability and cause the stainless steel bar to shift. This makes it difficult for the straightening plate to contact the two sides of the stainless steel bar to be straightened, reducing the quality and effect of the stainless steel bar straightening.

A stud is fixedly connected to the output end of the second stepper motor, and a connecting block is connected to the external thread of the stud.

[0008] As a further description of the above technical solution:

The limiting plate is slidably connected inside the two connecting grooves, and a positioning groove is provided at the bottom of the inner wall of the fixing frame.

[0010] As a further description of the above technical solution:

[0012] As a further description of the above technical solution:

[0013] The mounting bracket has sliding grooves on both sides, and a hydraulic rod is fixedly installed in the middle of the mounting bracket. A sliding rod is slidably connected inside the sliding groove.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model utilizes a positioning component to facilitate the limiting plate in limiting and fixing the stainless steel bar with a circular cross-section that needs to be straightened. This helps to reduce the displacement and deflection of the stainless steel bar during straightening, which would prevent the straightening plates on both sides from making contact with the sides of the stainless steel bar that need to be straightened. The positioning groove facilitates the positioning of the stainless steel bar with a circular cross-section, thereby improving the positioning accuracy during the straightening process. The moving block facilitates the movement of the cutting blade, which helps to cut the stainless steel bar according to the required length.

[0020] 2. By setting up a cleaning component, this utility model uses a short brush to easily clean and push away the debris that falls off the stainless steel bar after it is cut to a fixed length, thereby improving the cleanliness of the surface of the load-bearing plate. Furthermore, the pre-tension of the spring keeps the brush in close contact with the surface of the load-bearing plate, thus improving the quality of cleaning the surface of the load-bearing plate by the short brush.

A lead screw 5 is fixedly connected to the output end of the first stepper motor 4. A moving block 6 is threadedly connected to the external side of the lead screw 5. The moving block 6 is slidably connected inside the mounting frame 3 to facilitate indirect cutting. The blade 8 is adjusted to a certain position. A first hydraulic cylinder 7 is fixedly installed inside the moving block 6. The output end of the first hydraulic cylinder 7 is fixedly connected to the cutting blade 8. A force-bearing plate 9 is fixedly connected to the upper surface of the mounting plate 1 to protect the upper surface of the mounting plate 1. A second hydraulic cylinder 10 is fixedly installed on the lower surface of the mounting plate 1. A connecting frame 11 is fixedly connected to the output end of the second hydraulic cylinder 10. A straightening plate 12 is fixedly connected to one end of the connecting frame 11. When the two straightening plates 12 are close to each other, it is convenient to straighten the stainless steel bar. A positioning component is provided on one side of the mounting plate 1.

[0032] As attached Figure 1 As shown, the positioning component includes a fixed frame 13, which is fixedly connected to one side of the mounting plate 1. A second stepper motor 14 is fixedly installed on one side of the fixed frame 13. A stud 15 is fixedly connected to the output end of the second stepper motor 14 to facilitate the movement of the connecting block 16.

[0033] As attached Figure 5 As shown, the stud 15 is externally threaded to a connecting block 16, and has an internal threaded hole that matches the stud 15, for moving the limiting plate 17. The limiting plate 17 is fixedly connected to one side of the connecting block 16, and the limiting plate 17 is convenient to limit the stainless steel bar after it is pressed down.

[0034] As attached Figure 1 As shown, the fixed frame 13 has connecting grooves 18 on both sides, and the limiting plate 17 is slidably connected inside the two connecting grooves 18 to improve the stability of the limiting plate 17 when it moves. The bottom of the inner wall of the fixed frame 13 has a positioning groove 19 to facilitate the limiting of the stainless steel bar.

[0035] As attached Figure 6 As shown, a cleaning assembly is provided on one side of the mounting plate 1. The cleaning assembly includes a mounting bracket 20, which is fixedly connected to one side of the mounting plate 1. Slide grooves 21 are provided inside both sides of the mounting bracket 20 for the installation of slide rods 23. A hydraulic rod 22 is fixedly installed in the middle of the mounting bracket 20 to provide thrust to the mounting rods 24.

[0036] As attached Figure 3 As shown, a slide rod 23 is slidably connected inside the slide groove 21 and connected to the upper surface of the mounting rod 24 to improve the stability of the mounting rod 24 when it moves.

[0037] As attached Figure 7 As shown, the output end of the hydraulic rod 22 is fixedly connected to the mounting rod 24. The lower surface of the mounting rod 24 has multiple grooves 25 for mounting springs 28. A connecting rod 26 is slidably connected inside the grooves 25 for limiting the position of the springs 28. One end of each connecting rod 26 is fixedly connected to a short brush 27, which is a concave short brush. The grooves 25 are fixedly connected to the inside of the grooves 25, and one end of each spring 28 is fixedly connected to the inner wall of the brush 27. The springs 28 push the short brush 27.

[0038] Working principle: When processing stainless steel bars with a circular cross-section, the stainless steel bar is first passed through the inside of the fixed frame 13 and moved above the mounting plate 1, so that the stainless steel bar is placed inside the positioning groove 19 for pre-positioning. The stainless steel bar is rotated so that the two sides that need to be straightened are on the left and right sides. Then, the second stepper motor 14 is started, and its output end drives the stud 15 to rotate. When the stud 15 rotates, it drives the connecting block 16 to move down along the direction of the stud 15, thereby causing the limiting plate 17 to slide inside the two connecting grooves 18 and move down to the upper surface of the stainless steel bar to fix the stainless steel bar. Then, the two second hydraulic cylinders 10 are started at the same time. When the output end of the second hydraulic cylinder 10 retracts, it drives the connecting frame 11 to move, so that the connecting block 16 moves down along the direction of the stud 15. The connecting frame 11 pushes the straightening plate 12 to move. When the straightening plates 12 on both sides are close to each other, it is convenient to straighten the stainless steel bar. After straightening, the reverse function of the output end of the second stepper motor 14 is turned on, so that the limit plate 17 moves up and loosens the stainless steel bar. Then, the stainless steel bar is pushed to the force plate 9. When one end of the stainless steel bar abuts against one side of the fixed plate 2, the first stepper motor 4 is turned on. When the output end of the first stepper motor 4 drives the lead screw 5 to rotate, the lead screw 5 drives the moving block 6 to slide inside the mounting frame 3. The moving block 6 drives the cutting blade 8 to move to a suitable position distance through the first hydraulic cylinder 7. Then, the first hydraulic cylinder 7 is started. Under the action of its output end moving down, it is convenient to drive the cutting blade 8 to move down and cut the stainless steel bar.

[0039] When residue remains on the surface of the force plate 9 after cutting, the hydraulic rod 22 is activated, causing its output end to drive the mounting rod 24 to move above the force plate 9. The mounting rod 24 then drives the short brush 27 to move. During the movement, the short brush 27 is pushed by the spring 28, and the connecting rod 26 slides inside the groove 25, so that the short brush 27 is in close contact with the surface of the force plate 9, making it easier to clean and push out debris and impurities from the surface of the force plate 9.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
