Description

Technical Field

[0001] This utility model relates to the field of metal processing equipment, specifically a guide assembly support and fine-tuning mechanism. Background Technology

[0002] In metal processing (such as steel cutting), the guide assembly is the core component controlling material transport and positioning, and its support stability directly determines the cutting accuracy. Existing guide assembly support structures have the following technical defects, which restrict processing quality and efficiency: The clamping structure is not adjustable, resulting in poor adaptability: Traditional guide assemblies typically use fixed-angle flat plates or rollers for clamping components, which can only accommodate steel of a single thickness. When faced with steel of varying thicknesses, thinner materials are prone to jumping due to insufficient clamping force, while thicker materials are prone to deformation due to excessive compression, making it impossible to meet the processing requirements of different specifications.

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.

[0015] Please see Figure 1-5 This utility model provides a technical solution: a guide assembly support and fine-tuning mechanism, including a guide assembly 1. A connecting port 4 is provided on the upper side of the guide assembly 1. A rotating rod 5 is rotatably connected to the guide assembly 1, directly opposite the connecting port 4, via a deep groove ball bearing. Two sets of cutting blades 7 are fixedly connected to the outside of the rotating rod 5 via a key connection. The cutting blades 7 are high-speed steel blades with sharp edges, used for cutting steel. The cutting blades 7 are rotatably connected to the guide assembly 1 and the connecting port 4 to ensure no interference during cutting. Several sets of control grooves 8 are evenly distributed around the rotating rod 5. The control grooves 8 are staggered with the cutting blades 7 to avoid interference with the cutting blades. 7. Interference, while ensuring that the control groove 8 covers the width of the steel. The control groove 8 is rotatably connected to the rotating shaft 9 through the needle roller bearing. The outer side of the middle of the rotating shaft 9 is fixedly connected to the gear 10 through the key connection. The two ends of the rotating shaft 9 are fixedly connected to the push plate 11 through welding. The inner side of the push plate 11 is pasted with anti-slip rubber pad to enhance the friction with the steel. The gear 10 is meshed with the rack 12. The circumferential rack 12 is fixedly connected to the control rod 6 through welding. The control rod 6 is slidably connected to the inside of the rotating rod 5 and can slide back and forth along the control rod 6. The two ends of the control rod 6 penetrate the rotating rod 5 and are fixedly connected to the control plate 13 through bolts.

[0016] One end of the rotating rod 5 is fixedly connected to the connecting plate 14 by welding. One side of the connecting plate 14 is rotatably connected to the first threaded rod 15 by a thrust ball bearing. The first threaded rod 15 is threadedly connected to the inside of one side of the control plate 13. The other side of the control plate 13 is slidably connected to the first sliding rod 16. The other end of the first sliding rod 16 is fixedly connected to the connecting plate 14 by welding, which provides guidance for the sliding of the control plate 13 and prevents rotation.

[0017] The front side of the guide assembly 1 is fixedly connected to the feed port 2 by welding. The feed port 2 is a flared steel plate to guide the steel to enter smoothly. The lower side of the guide assembly 1 is rotatably connected to the rolling wheel 17 by a deep groove ball bearing to reduce the resistance of steel conveying.

[0018] The rear side of the guide assembly 1 is fixedly connected to the discharge port 3 by welding. Inside the discharge port 3, there are two sets of isolation plates 28 facing the cutting blade 7, which are used to separate the cut steel and prevent them from colliding and shifting.

[0019] The upper front side of the guide assembly 1 is connected to a second threaded rod 19 by a thread. The bottom of the second threaded rod 19 is rotatably connected to a mounting bracket 20 by a thrust ball bearing. Two sets of second sliding rods 21 are fixedly connected to the upper sides of the mounting bracket 20 by welding. The second sliding rods 21 are slidably connected inside the guide assembly 1 to restrict the rotation of the mounting bracket 20. Lifting grooves 22 are opened on both sides of the mounting bracket 20 along the height direction. Lifting blocks 23 are slidably connected inside the lifting grooves 22. A connecting shaft 24 is fixedly connected between the two lifting blocks 23 by welding. A pressure roller 25 is rotatably connected to the outside of the connecting shaft 24 by a deep groove ball bearing (model 6203). The pressure roller 25 is located behind the feed inlet 2 and is used to assist in pressing the steel.

[0020] Inside the lifting groove 22, a guide rod 26 is fixedly connected by welding. The guide rod 26 is slidably connected inside the lifting block 23. A spring 27 is fixedly connected to the lower part of the lifting block 23 by spot welding. The spring 27 is sleeved on the outside of the guide rod 26 to prevent the spring 27 from shifting. The lower part of the spring 27 is fixedly connected to the inner wall of the lifting groove 22 by spot welding. Under normal conditions, the spring 27 drives the lifting block 23 to move downward to ensure that the pressure roller 25 can assist in pressing the steel.

[0021] The first sliding rod 16 and the second sliding rod 21 have scale lines 18 laser-etched on one side for precise observation of the adjustment amount and to improve the fine-tuning accuracy.

[0022] Working principle: When using this utility model, the hand-tightening end of the first threaded rod 15 is rotated according to the thickness of the steel to be processed; the first threaded rod 15 is threadedly connected to the control plate 13, and the first sliding rod 16 restricts the rotation of the control plate 13. Therefore, when the first threaded rod 15 rotates, the control plate 13 slides along the first sliding rod 16 towards or away from the connecting plate 14. The control panel 13 drives the control lever 6 to slide synchronously, and the control lever 6 pushes the circumferential rack 12 to move; the rack 12 meshes with the gear 10, driving the gear 10 to rotate synchronously with the rotating shaft 9; the rotating shaft 9 drives the push plates 11 at both ends to rotate around the rotating shaft 9, changing the extension length of the push plates 11, thereby ensuring that one end of the push plate 11 can press steel of different thicknesses. By observing the adjustment amount through the scale line 18 of the first sliding rod 16, ensure that the angle of the push plate 11 is adapted to the thickness of the steel, stop rotating the first threaded rod 15, and fix the angle of the push plate 11; Rotate the hand-tight knob of the second threaded rod 19, and the second threaded rod 19 is threadedly connected to the guide assembly 1, driving the mounting bracket 20 to rise and fall along the second sliding rod 21; observe the height of the pressure roller 25 through the scale line 18 of the second sliding rod 21, so that the bottom of the pressure roller 25 contacts the upper surface of the steel; after the pressure roller 25 contacts the steel, continue to fine-tune the second threaded rod 19, so that the lifting block 23 slides down along the guide rod 26, compressing the spring 27; the elastic force of the spring 27 is transmitted to the pressure roller 25 through the lifting block 23 and the connecting shaft 24, so that the pressure roller 25 presses the steel with a stable elastic force, buffering the fluctuations during the conveying process; The steel to be cut is fed into the feed port 2 and conveyed forward along the roller 17. The pressure roller 25 elastically presses the upper surface of the steel to prevent it from jumping upward. After the steel enters the guide assembly 1, the push plates 11 on both sides press the upper part of the steel at the adjusted angle to prevent the steel from jumping up and down through rigid fixation. The rotating rod 5 drives the cutting blade 7 to rotate and cut the steel. The cut steel is smoothly discharged along the discharge port 3 under the separation of the partition plate 28 to avoid collision and deviation.
