Description

Technical Field

[0001] This invention relates to the field of forging transfer technology, specifically to a transfer trolley for hot forging production that facilitates material handling. Background Technology

[0002] In the hot forging production process, the material transfer trolley is the core auxiliary equipment for workpiece transfer. It is mainly used to complete the grabbing, shifting and conveying of high-temperature forgings to ensure continuous production on the forging production line.

[0003] Currently, traditional hot forging material transfer trolleys on the market have limited functions, only possessing basic hooking, clamping, and workpiece transfer capabilities. They can only achieve the positional transfer of forgings and lack any oxide scale cleaning, impurity blowing, or surface protection treatment mechanisms. After hot forgings are formed at high temperatures, a large amount of oxide scale will quickly form on the surface. If it cannot be cleaned in time during the transfer process, the residual oxide scale will be squeezed into the forging matrix during subsequent secondary forging and hot straightening processes, resulting in quality defects such as inclusions, pits, and cracks, which will significantly reduce the yield of finished forgings. At the same time, the hard oxide scale will continuously wear down the forging mold cavity, increasing mold wear and production costs. Summary of the Invention

[0004] The purpose of this invention is to provide a transfer trolley for hot forging production that facilitates material handling, thereby addressing the problem mentioned in the background art. Currently available traditional hot forging material handling transfer trolleys have limited functionality, only possessing basic hooking, clamping, and workpiece transfer capabilities. They can only achieve the positional transfer of forgings and lack any oxide scale cleaning, impurity blowing, or surface protection mechanisms. After high-temperature forming, a large amount of oxide scale rapidly forms on the surface of hot forgings. If this scale cannot be cleaned in time during transfer, the residual oxide scale will be squeezed and embedded into the forging matrix during subsequent secondary forging and hot straightening processes, resulting in quality defects such as inclusions, pitting, and cracks. This significantly reduces the yield rate of finished forgings. Furthermore, the hard oxide scale continuously wears down the forging mold cavity, increasing mold wear and production costs.

[0009] Preferably, the cleaning component is provided with an air jet channel, which is connected to the transmission rod, and multiple nozzles are provided on the air jet channel.

[0010] Preferably, the spraying mechanism includes a first pressure rod and a second pressure rod slidably connected to both sides of the cleaning component. A pressure spring is fixedly connected to both the first and second pressure rods. The other end of the pressure spring is fixedly connected to the cleaning component.

[0011] Preferably, slide rails are fixedly connected to both sides of the transmission rod, a counterweight is slidably connected inside the slide rail, a tension spring is fixedly connected to the counterweight, the other end of the tension spring is fixedly connected to the inner wall of the slide rail, and a third wedge is fixedly connected to the bottom of the counterweight.

[0012] Preferably, a first slide rod is fixedly connected to both sides of the second telescopic scraper, and a second slide rod is fixedly connected to both sides of the second scraper brush. Both the first and second slide rods slide through to the outside of the cleaning component. A return spring is sleeved on the second slide rod, and the end of the second slide rod contacts a third wedge.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This device integrates rotary scraping and high-pressure blowing to remove oxide scale. The cleaning part is equipped with a first scraper brush and a second scraper brush to scrape the oxide scale on the upper and lower surfaces of the forging from all directions. The rotation of the transmission rod generates centrifugal force to automatically open the air path, and the high-pressure airflow blows away the detached oxide debris, preventing the debris from adhering to the workpiece again. For deep and stubborn oxide scale with strong adhesion, the device relies on the combination of flipping teeth and torsion springs to form an abnormal noise warning structure, which can quickly identify stubborn oxide scale without manual inspection and treat it in advance, preventing oxide scale from being pressed into the forging matrix to form interlayer and pit defects, while reducing the wear of hard oxide particles on the forging die.

[0015] 2. This device can automatically switch working conditions after the oxide scale is cleaned. It uses the centrifugal force generated by the high-speed rotation of the transmission rod to automatically switch between the scraper brush and the telescopic scraper. The small-diameter liquid inlet hole, together with high-pressure air, disperses the water-based graphite lubricant into uniform atomized droplets and sprays them out to form a continuous and uniform protective film on the surface of the forging. The lubricating film can not only slow down the secondary oxidation of the forging during transportation, but also reduce the frictional resistance between the workpiece and the mold during forging, and reduce the defects of forging such as scratches and folds.

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

[0019] Example 1: Please refer to Figure 1 - Figure 13 A transfer trolley for hot forging production, facilitating material handling, includes a trolley 1 and a forging 6. The trolley 1 is equipped with a lifting rail 2, and a hydraulic telescopic rod 3 is slidably connected inside the lifting rail 2. The end of the hydraulic telescopic rod 3 is equipped with a lower clamping hand 5 and an upper clamping hand 7. A mounting plate 4 is mounted on the hydraulic telescopic rod 3. Horizontal plates 10 are slidably connected to both sides of the mounting plate 4. Electric rods 9 are fixedly connected to both sides of the mounting plate 4, and the ends of the electric rods 9 are respectively fixedly connected to the corresponding horizontal plates 10. A transmission rod 14 is rotatably connected to both horizontal plates 10. The transmission rod 14 is hollow, and a cleaning component 11 is fixedly connected to the end of the transmission rod 14. The cleaning component 11 is equipped with an oxide scale removal mechanism and a spraying mechanism. The oxide scale removal mechanism includes a first scraper brush 20 and a first telescopic scraper 22 slidably connected to both sides of the cleaning component 11. A second scraper brush 25 and a second telescopic scraper 21 are slidably connected to the side of the cleaning component 11 closest to the transmission rod 14.

[0020] Both sides of the first scraper brush 20 and the first telescopic scraper 22 are fixedly connected with a return spring 26. The other end of the return spring 26 is fixedly connected to the cleaning component 11. The first scraper brush 20 and the first telescopic scraper 22 are respectively fixedly connected with a first wedge 27 and a second wedge 28.

[0021] A drive motor 12 is fixedly connected to the outer wall of the horizontal plate 10. A drive gear 13 is fixedly connected to the output end of the drive motor 12. A driven gear 15 is rotatably connected to the outer wall of the transmission rod 14. The driven gear 15 and the drive gear 13 are meshed. Multiple fixing parts 17 are fixedly connected to the driven gear 15. Rotating teeth 18 are rotatably connected to each of the multiple fixing parts 17. Torsion springs 19 are sleeved on the rotating teeth 18. Multiple baffles 16 are fixedly connected to the transmission rod 14. The multiple baffles 16 abut against the corresponding rotating teeth 18.

[0022] Both sides of the mounting plate 4 are fixedly connected to cylinders 43. The cylinders 43 have an air storage chamber 44 and a liquid storage chamber 45 inside. The end of the transmission rod 14 away from the cleaning component 11 rotates and passes through the air storage chamber 44. Both sides of the end of the transmission rod 14 located in the air storage chamber 44 are fixedly connected to limit rails 47. Both sides of the limit rails 47 are slidably connected to a sealing component 46. Both sides of the limit rails 47 are fixedly connected to an outward push spring 48. The other end of the outward push spring 48 contacts the sealing component 46.

[0023] The cleaning component 11 is provided with an air jet channel 23, which is connected to the transmission rod 14, and multiple nozzles 24 are provided on the air jet channel 23.

[0024] In this embodiment, during actual operation, the operator pushes the trolley 1 to the appropriate work position for material handling, then extends the hydraulic telescopic rod 3, driving the lower clamping hand 5 and the upper clamping hand 7 mounted on the mounting plate 4 to close synchronously in opposite directions, thus completing the clamping and positioning of the forging 6 (e.g., Figure 2As shown), after the lower clamping hand 5 and the upper clamping hand 7 jointly and stably clamp the forging 6, the hydraulic telescopic rod 3 is controlled to retract. During the retraction of the hydraulic telescopic rod 3, the forging 6, which is clamped and fixed by the lower clamping hand 5 and the upper clamping hand 7, is moved synchronously. When the forging 6 is precisely aligned with the working area of ​​the cleaning part 11, the hydraulic telescopic rod 3 stops retracting. Then, the upper electric rod 9 is controlled to retract. During the retraction of the electric rod 9, the upper cleaning part 11 is moved vertically downward via the horizontal plate 10. This feeding action is synchronized with the upper clamping hand 7 to release the forging 6. The lower clamping hand 5 alone supports and clamps the forging 6, and the upper clamping hand 7 releases the forging. After part 6 is removed, the outer wall area of ​​forging 6 previously covered and fitted by the upper clamping hand 7 is completely exposed, leaving sufficient space for cleaning. After the upper clamping hand 7 releases forging 6, the upper cleaning part 11 moves down and fits against the outer wall of forging 6. Then, the matching drive motor 12 is started. The drive motor 12 outputs torque to drive the drive gear 13 to rotate. The drive gear 13 meshes with the driven gear 15 to rotate synchronously. Multiple sets of rotating teeth 18 are integrally arranged on the outer circumference of the driven gear 15. The multiple sets of rotating teeth 18 abut against and engage with the baffle 16 fixed on the transmission rod 14 to limit the rotation. When the driven gear 15 rotates, it can rely on the engagement of the rotating teeth 18 and the baffle 16 to limit the rotation. The combined structure drives the transmission rod 14 to rotate synchronously on the same axis. During the rotation of the transmission rod 14, it further drives the cleaning part 11 to rotate as a whole. In the rotating state, the first scraper brush 20 and the second scraper brush 25 mounted on the upper cleaning part 11 continuously rub and scrape the upper surface of the forging 6, peeling off the oxide scale on the surface of the forging 6. Timely removal of oxide scale can prevent oxide scale from being pressed into the matrix of the forging 6 in subsequent forging processes, forming defects such as interlayers and pits. At the same time, it reduces the wear of hard oxide particles on the forging mold cavity, effectively improving the finished product qualification rate of the forging 6 and extending the service life of the mold. The synchronous stage of the transmission rod 14 driving the cleaning part 11 to rotate and scrape off the oxide scale, The centrifugal force generated by the rotation of the moving rod 14 can overcome the pre-tightening force of the external push spring 48, and throw the sealing part 46 to both sides of the transmission rod 14. After the sealing part 46 is moved, it releases the blockage of the medium channel at the upper end of the transmission rod 14. The high-pressure compressed air stored in the air storage chamber 44 inside the cylinder 43 can be introduced into the internal cavity of the transmission rod 14 through the channel at the upper end of the transmission rod 14, and then transported along the jet channel 23. Finally, it is directionally sprayed onto the upper surface of the forging 6 through multiple sets of nozzles 24. The airflow can promptly blow away the oxide scale debris scraped off by the first scraper brush 20 and the second scraper brush 25, preventing the debris from adhering to the surface of the forging 6 and causing secondary pollution.

[0025] During the oxide scale removal process, if stubborn oxide scale exists on the surface of forging 6, this type of oxide scale is mostly due to deep oxidation caused by prolonged exposure of forging 6 to air at high temperatures. It is metallurgically bonded to the base material of forging 6, and its adhesion is much stronger than loose floating scale. Hard oxide scale will create a hard obstruction to the rotating cleaning part 11, directly causing the cleaning part 11 and the transmission rod 14 to stop rotating. However, the drive motor 12 continues to output power to drive the driven gear 15 to keep rotating. The torsional torque generated by the locking of the transmission rod 14 and the continuous rotation of the driven gear 15 can overcome the preset elasticity of the torsion spring 19, forcing the turning tooth 18 to deflect at an angle. The driven gear 15 enters the idling condition. When the driven gear 15 is idling, the turning tooth 18 will continuously contact and impact the baffle 16, producing a regular high-frequency impact noise. The operator can quickly identify the presence of stubborn oxide scale on the surface of forging 6 by the abnormal noise and remove forging 6 in time. Pre-treatment eliminates the production of defective products with oxide inclusions from the source, reducing the scrap rate in subsequent forging (it should be noted that the spring force parameters of the torsion spring 19 are precisely matched, and the frictional resistance caused by ordinary loose oxide scale is insufficient to overcome the spring force of the torsion spring 19, so there will be no false triggering of the idle alarm). After the upper cleaning part 11 completes the oxide scale cleaning process on the upper surface of the forging 6, the upper electric rod 9 is extended to drive the upper cleaning part 11 to lift up and detach from the outer wall of the forging 6. Then the upper clamping hand 7 re-clamps the forging 6, and the lower clamping hand 5 simultaneously releases the forging 6. The bottom area of ​​the forging 6, which was originally covered by the lower clamping hand 5, is completely exposed. The entire operation process of the upper cleaning part 11 is repeated to drive the lower cleaning part 11 to feed upward and fit against the lower surface of the forging 6. The first scraper brush 20 and the second scraper brush 25 installed on the lower cleaning part 11 complete the all-round scraping and cleaning of the oxide scale on the lower surface of the forging 6.

[0026] Example 2: Please refer to Figure 1 - Figure 13 The spraying mechanism includes a first pressure rod 29 and a second pressure rod 30 slidably connected to both sides of the cleaning component 11. A pressure spring 31 is fixedly connected to both the first pressure rod 29 and the second pressure rod 30. The other end of the pressure spring 31 is fixedly connected to the cleaning component 11. A connecting plate 36 is fixedly connected to both ends of the first pressure rod 29 and the second pressure rod 30. A roller 35 is rotatably connected to the connecting plate 36.

[0027] Both sides of the transmission rod 14 are fixedly connected to slide rails 32. A counterweight 33 is slidably connected inside the slide rail 32. A tension spring 34 is fixedly connected to the counterweight 33. The other end of the tension spring 34 is fixedly connected to the inner wall of the slide rail 32. A third wedge 37 is fixedly connected to the bottom of the counterweight 33.

[0028] The second telescopic scraper 21 is fixedly connected to both sides of the first slide rod 38, and the second scraper brush 25 is fixedly connected to both sides of the second slide rod 41. The first slide rod 38 and the second slide rod 41 slide through to the outside of the cleaning member 11. A return spring 42 is sleeved on the second slide rod 41. The end of the second slide rod 41 contacts the third wedge 37. The cleaning member 11 is fixedly connected to both sides of the upright plate 39. The end of the upright plate 39 is rotatably connected to the connecting rod 40. The two sides of the connecting rod 40 are rotatably connected to the second slide rod 41 and the first slide rod 38, respectively.

[0029] Both sides of the transmission rod 14 are connected to liquid inlet pipes 49, and liquid inlet holes 52 are opened on the liquid inlet pipes 49. A movable ring 50 is slidably connected to the liquid inlet pipes 49, and a tension spring 51 is fixedly connected to the movable ring 50. The other end of the tension spring 51 is fixedly connected to the outer wall of the transmission rod 14. A fixed rod is fixedly connected to the movable ring 50, and a blocking plug 8 is connected to the end of the fixed rod. The blocking plug 8 blocks the liquid inlet hole 52.

[0030] In this embodiment, after the oxide scale on both the upper and lower sides of the forging 6 has been completely and normally removed, the upper clamping hand 7 releases the forging 6 again, leaving only the lower clamping hand 5 to clamp and fix the forging 6. The upper electric rod 9 is then controlled to retract, causing the upper cleaning part 11 to adhere to the upper surface of the forging 6. The output power of the matching drive motor 12 is increased, and the drive gear 13 and the driven gear 15 drive the transmission rod 14 to rotate at high speed. The high-speed rotation of the transmission rod 14 generates a strong centrifugal force, causing the counterweight 33 to overcome the tension of the tension spring 34 and slide outward toward the slide rail 32. The counterweight 33 simultaneously drives the third wedge 37 to move outward. In this state, the third wedge 37 disengages from the contact limit with the second slide rod 41, and the second slide rod 41 will rise upward under the elastic force of the return spring 42. During the rising process of the second slide rod 41, the first slide rod 38 moves vertically downward in conjunction with the connecting rod 40 (refer to...). Figure 10 The first sliding rod 38 moves downward, causing the second telescopic scraper 21 to extend from the inner cavity of the cleaning part 11 and fit against the outer wall of the forging 6. When the counterweight 33 slides to the outside of the slide rail 32, the third wedge 37 presses against the roller 35 and moves downward. The roller 35 presses down on the connecting plate 36 simultaneously. The connecting plate 36 pushes the first pressure rod 29 and the second pressure rod 30 to move downward simultaneously (see reference). Figure 9As the first pressure rod 29 moves downward, it disengages from the first wedge 27, releasing the limiting constraint on the first wedge 27. The first scraper brush 20 retracts into the cleaning part 11 under the elastic force of the matching return spring 26, completely detaching from the surface of the forging 6. The second pressure rod 30 moves downward, its rear end pressing against the second wedge 28, driving the first telescopic scraper 22 to extend outward from the inner cavity of the cleaning part 11, replacing the first scraper brush 20 in contact with the outer wall of the forging 6. Simultaneously, the centrifugal force generated by the high-speed rotation of the transmission rod 14 drives the moving ring 50 to slide outward from the liquid inlet pipe 49, overcoming the tension of the tension spring 51. When the moving ring 50 moves outward, it drives the blocking plug 8 to move synchronously outward through the fixed rod. As the liquid inlet 52 is unblocked, the water-based graphite lubricant stored in the liquid storage chamber 45 inside the cylinder 43 flows into the transmission rod 14 through the open liquid inlet 52. After being fully mixed with the high-pressure compressed air flowing inside the transmission rod 14, it is introduced into the jet channel 23 and finally atomized and sprayed onto the upper surface of the forging 6 through multiple sets of nozzles 24. The extended first telescopic scraper 22 and second telescopic scraper 21 rotate synchronously with the cleaning part 11 to roll and spread the atomized water-based graphite lubricant sprayed onto the outer wall of the forging 6, forming a continuous and uniform lubricating protective film on the surface of the forging 6. After the coating process on the upper surface of the forging 6 is completed, the above media coating process is repeated. The lower cleaning component 11 is driven to adhere to the lower surface of the forging 6, completing the uniform coating of water-based graphite lubricant on the bottom of the forging 6. The uniform coating of the water-based graphite lubricant film on the surface of the forging 6 can slow down secondary oxidation during the transfer process. Simultaneously, the lubricant film can reduce forging friction resistance, minimizing damage to the forging 6 during subsequent forging processes. After the coating process is completed, the operator continuously pushes the trolley 1 to move the forging 6 to the designated downstream processing station. The lower clamping hand 5 and the upper clamping hand 7 are controlled to simultaneously release the forging 6, allowing it to be sent for subsequent processing stages such as edge trimming, heat correction, and secondary forging. (It should be noted that the inlet hole 52 is designed with a small diameter structure, allowing lubricant to flow out...) The droplets are tiny and are instantly dispersed into uniform, fine atomized droplets by the airflow upon contact with high-pressure compressed air, ensuring the uniformity of the sprayed medium. A one-way valve is installed inside the liquid inlet pipe 49, allowing only one-way delivery of water-based graphite lubricant and preventing backflow of high-pressure compressed air inside the transmission rod 14 into the liquid storage chamber 45. An air inlet is provided on the side wall of the air storage chamber 44, and a liquid inlet is provided on the side wall of the liquid storage chamber 45, facilitating the replenishment of compressed air and lubricating medium during operation. At the same time, the compressed air is heated by the built-in heater in the air storage chamber 44, so that the temperature of the forging 6 will not drop too quickly when it is blown towards the forging 6. Sealing rings are provided at the connection between the transmission rod 14 and the air storage chamber 44 and the liquid storage chamber 45 to prevent medium leakage.

[0031] It should be noted that the pressure spring 31 and return spring 42 in the whole structure are both of low elasticity specifications, which are only used for the reset and rebound of the corresponding moving components after the action is completed. They do not bear pressure under scraping, clamping and coating conditions. The first scraper brush 20 is made of hard tungsten cobalt alloy, which has high overall hardness, wear resistance and impact resistance. It can stably scrape off the hard oxide scale on the surface of the forging 6. It is not easy to chip or deform under high temperature conditions. The first telescopic scraper 22 and the second telescopic scraper 21 are made of high temperature resistant silicon molybdenum alloy. The material has excellent toughness, smooth working surface and low friction. It will not scratch the forming surface of the forging 6 when rolling graphite emulsion. It can withstand the radiant heat of the high temperature forging 6 for a long time without softening and failure.
