Description

Technical Field

[0001] This utility model relates to the field of hot forging forming and processing, and in particular to an anti-deviation guide structure for a hot forging billet conveying track. Background Technology

[0002] Hot forging is a core process for forming and processing metal parts, and it is widely used in the production of key components in the automotive, construction machinery, aerospace and other fields. The process of conveying hot forging billets from the heating furnace to the forging press is a critical link in the hot forging production line. The straightness and positional accuracy of the billet conveying directly determine whether the billet can be accurately fed into the forging die cavity. This not only affects the forming accuracy and product qualification rate of the final forging, but also relates to the service life of the die and the operational safety of the production line. Therefore, a conveying and guiding structure adapted to the high temperature of hot forging billets is an important foundation for ensuring the stable and efficient operation of the hot forging production line.

[0003] However, most conventional billet conveying tracks in current hot forging production lines adopt flat roller conveying structures without guide limits, which have serious defects in actual production. Hot forging billets are heavy after being heated to high temperatures and are prone to oxide scale buildup. During conveying, they are easily deviated to the left or right due to factors such as roller speed deviation, irregular billet cross-section, and equipment vibration. This can lead to inaccurate billet placement into the die, requiring manual alignment and significantly reducing production efficiency. In severe cases, it can cause billet jamming, impact with the die, or even falling off the roller conveyor, resulting in waste of high-temperature billet materials and potentially causing equipment damage, burns, and other safety accidents. This approach fails to meet the continuous and automated production requirements of hot forging production lines. Therefore, a deviation-prevention guide structure for hot forging billet conveying tracks is proposed to solve these problems. Utility Model Content

[0034] 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.

[0035] Reference Figures 1-3 An embodiment of this utility model is provided: an anti-deviation guide structure for a hot forging billet conveying track, including a frame 1, a conveying roller 2 rotatably connected to the inner side wall of the frame 1, and a hot forging billet can be conveyed through multiple sets of conveying rollers 2. An anti-deviation mechanism 3 is provided on the upper surface of the frame 1, and a dust blowing assembly 4 is provided on the front surface of the frame 1.

[0036] Reference Figures 2-3 The anti-deviation mechanism 3 includes a contact roller 31, with sliders 38 fixedly connected to both sides of the contact roller 31. The sliders 38 are elastically connected to the inner side wall of the frame 1 via springs b39. One end of the spring b39 is fixedly connected to the lower surface of the slider 38, and the other end of the spring b39 is fixedly connected to the inner side wall of the frame 1. The initial height of the contact roller 31 is higher than that of the conveying roller 2, so that when the hot forging billet is conveyed by the conveying roller 2, its bottom end will contact the upper surface of the contact roller 31, thereby pushing the contact roller 31 to drive the slider 38 down and causing the spring b39 to be elastically compressed until the hot forging billet passes through the contact roller 31. At this point, the elastic action of the spring b39 will reset the contact roller 31, the connecting rod 32, and the slider 38.

[0037] Specifically, the slider 38 is slidably connected to the inner side wall of the frame 1. A connecting rod 32 is fixedly connected to the lower surface of the contact roller 31. Two sets of hinge rods 33 are hinged to the lower surface of the connecting rod 32. A U-shaped rod 34 is hinged to the end of each set of hinge rods 33 away from the connecting rod 32. When the contact roller 31 is contacted and descends by the hot forged billet, it will drive the connecting rod 32 to descend synchronously. The U-shaped rods 34 are synchronously pulled together by the inverted V-shaped hinge rods 33. A guide plate 36 is elastically connected to the side wall at the top of the U-shaped rod 34 through a pressure spring 35. One end of the pressure spring 35 is fixedly connected to the top of the U-shaped rod 34. The other end of the pressure spring 35 is fixedly connected to the rear end surface of the guide plate 36. The function of the pressure spring 35 is to provide elastic support to the hot forging billet when the guide plate 36 comes into contact with the hot forging billet, so that it can be firmly attached to the outer surface of the hot forging billet. The rear end of the guide plate 36 is fixedly connected to the guide rod 37. The U-shaped rod 34 passes through and is slidably connected to the inner wall of the bottom end of the frame 1. The guide rod 37 passes through and is slidably connected to the inner wall of the top end of the U-shaped rod 34. The function of the guide rod 37 is to provide guiding support for the movement of the guide plate 36. The guide plate 36 is trapezoidal, so that the hot forging billet passes through the inclined surface first.

[0038] Reference Figure 1 and Figure 4 The dust blowing assembly 4 includes a connecting box 41, which is fixedly connected to the upper surface of the front end of the frame 1. A fan 42 is fixedly connected to the upper surface of the connecting box 41. The fan 42 is a telescopic flexible hose, and the external air can be pumped into the dust blowing head 47 through the telescopic hose 43 by the drive of the fan 42, and dust is blown on the exposed surface of the hot forging billet to avoid the adsorption of impurities. The telescopic hose 43 is fixedly connected to the surface of the fan 42. A motor 44 is fixedly connected to the bottom of the outer wall of the connecting box 41. A rotating disk 45 is fixedly connected to the output shaft of the motor 44. A connecting rod 46 is hinged to the surface of the upper surface of the rotating disk 45 away from the center point. The dust blowing head 47 is fixedly connected to the lower surface of the telescopic hose 43. The rotating disk 45 is rotatably connected to the inner side wall of the connecting box 41.

[0039] Reference Figure 4 The inner side wall of the connecting box 41 is provided with a sliding groove. The dust blowing head 47 is slidably connected to the inner wall of the sliding groove of the connecting box 41. The surface of the dust blowing head 47 is provided with an arc-shaped groove. The end of the connecting rod 46 away from the rotating disk 45 is hinged and slidably connected to the inner wall of the arc-shaped groove of the dust blowing head 47. When the motor 44 drives the rotating disk 45 to rotate, the connecting rod 46 hinged to its surface will reciprocate around the center, thereby sliding in the arc-shaped groove of the dust blowing head 47 and reciprocatingly pushing the dust blowing head 47 to slide inside the connecting box 41, thereby blowing dust off the surface of the hot forging billet.

[0040] Working principle: When in use, first start the drive mechanism of the inner conveyor roller 2 of the frame 1, which drives multiple sets of conveyor rollers 2 to rotate synchronously and at a uniform speed, providing stable forward conveying power for hot forging billets. At the same time, start the fan 42 and motor 44 of the dust blowing assembly 4 to prepare for the pre-cleaning of the billets.

[0041] The hot forging billet enters the conveying track from the front end of the frame 1, and first passes through the working area of ​​the dust blowing assembly 4: the fan 42 pressurizes the external air and then delivers it to the dust blowing head 47 through the telescopic hose 43, and finally sprays it out at high speed from the air outlet of the dust blowing head 47; at the same time, the output shaft of the motor 44 drives the rotating disk 45 to rotate continuously in a circumferential direction, and the connecting rod 46 eccentrically hinged on the rotating disk 45 moves back and forth in sync with the rotating disk 45. The end of the connecting rod 46 slides synchronously in the arc-shaped groove of the dust blowing head 47, thereby driving the dust blowing head 47 to slide continuously left and right along the sliding groove on the inner side of the connecting box 41. The telescopic hose 43 can adaptively extend and retract with the reciprocating sliding of the dust blowing head 47 to ensure the continuous unobstructed air supply passage, so that the high-pressure airflow sprayed from the dust blowing head 47 can fully cover the upper surface of the hot forging billet, thoroughly blowing away the oxide scale, dust, impurities and other substances attached to the surface of the billet, preventing impurities from being pressed into the interior of the forging after entering the forging process with the billet, and ensuring the forming quality of the forging.

[0042] After the hot forging billet has been cleaned, it continues to be conveyed forward by the conveyor roller 2 and enters the working area of ​​the anti-deviation mechanism 3. The front end of the billet first contacts the contact roller 31, which is initially higher than the conveyor roller 2. The weight of the billet and the downward pressure of the conveyor push the contact roller 31 to move downward. The contact roller 31 drives the sliders 38 fixed on both sides to slide downward along the inner side wall of the frame 1, and simultaneously compresses the spring b39 at the bottom of the slider 38 to store energy. At the same time as the contact roller 31 moves downward, it drives the connecting rod 32 fixed on its lower surface to descend synchronously. The connecting rod 32 drives the two sets of hinged rods 33 with their bottom hinges arranged in an inverted V-shape to deflect synchronously. As the connecting rod 32 descends, the two sets of hinged rods 33 synchronously pull the U-shaped rods 34 with their ends hinged together along the inner wall of the bottom of the frame 1, so that the pressure springs 35 at the top of the two sets of U-shaped rods 34 respectively adhere to the left and right side walls of the hot forging billet, forming a centering guide limit.

[0043] During the process of the pressure spring 35 adhering to the side wall of the billet, the guide plate 36 between the pressure spring 35 and the U-shaped rod 34 can generate adaptive elastic deformation according to the width of the billet, providing flexible clamping and guiding force for the billet. This avoids scratches and deformations on the surface of the high-temperature billet caused by rigid clamping, and firmly restricts the conveying trajectory of the billet, preventing it from shifting left or right during conveying. The guide rod 37 slides through the inner wall of the top of the U-shaped rod 34, providing stable guiding support for the extension and retraction of the guide plate 36 and the adhering of the pressure spring 35, avoiding swaying during the guiding process. At the same time, the front end of the guide plate 36 is designed with a trapezoidal bevel, which can adapt to billets of different diameters and cross-sectional specifications, allowing the pressure spring 35 to adhere smoothly to the surface of the billet, further improving the adaptability of the guide.

[0044] After the hot forging billet has completely passed through the contact roller 31, the downward pressure of the billet on the contact roller 31 disappears, the compressed spring b39 releases its elastic potential energy, and pushes the slider 38 to reset upward along the inner side of the frame 1. Simultaneously, it drives the contact roller 31 and the connecting rod 32 to rise upward. The connecting rod 32 pushes the two sets of U-shaped rods 34 away from each other and resets through the hinge rod 33, releasing the guide limit on the billet and waiting for the next set of billets to enter, thus realizing continuous conveying and anti-deviation operation.

[0045] 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.
