Description

Technical Field

[0001] This utility model relates to the field of billet precision forging technology, specifically a billet loading mechanism for precision forging. Background Technology

[0002] Precision forging is a manufacturing process that uses precision forging technology to process metal billets into high-precision, high-performance forgings. This process typically involves heating a cylindrical metal billet to a high temperature to induce plastic deformation, followed by shaping in a forging press. Precision forgings are widely used in key components in aerospace, automotive, and energy industries, and their surface quality and dimensional accuracy directly affect the mechanical properties and service life of the final product.

[0003] In a precision forging production line, the heated high-temperature billet needs to be lifted and conveyed to the forging station step by step through a stepped feeding mechanism. Traditional feeding mechanisms usually adopt a stepped plate structure with fixed gaps: the billet rolls between the stepped plates by gravity, and step feeding is achieved through the periodic lifting and lowering of the steps.

[0004] However, existing stepped material distribution mechanisms have the following shortcomings: the vertical gap between the stepped plates cannot adapt to the billet diameter tolerance. When the billet diameter exceeds the tolerance, it is easy to get stuck in the step gap, causing the mechanism to jam or the billet to be damaged.

[0005] Traditional stepped cleaning systems lack vibration or scraping mechanisms, relying solely on gravity to remove oxide scale and debris, resulting in low cleaning efficiency. Accumulated oxide scale can clog the internal mechanisms, affecting material distribution stability and increasing equipment maintenance costs.

[0006] Therefore, we propose a billet feeding mechanism for precision forging to solve the problems mentioned above. Utility Model Content

[0007] This utility model provides a billet feeding mechanism for precision forging, which can solve the problem that the existing stepped feeding mechanism cannot effectively handle the billet diameter tolerance and real-time oxide scale removal due to inherent structural defects, resulting in frequent jamming, blockage and manual intervention, which seriously restricts the continuity and automation of precision forging production.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] A billet forging feeding mechanism includes a working platform, a material rack is provided on the working platform, the material rack is slidably connected to the upper part of the working platform, and a hydraulic push rod is provided on the working platform to push the material rack to slide.

[0010] The front end of the material rack is provided with a fan-shaped material trough, and a motion cleaning component is provided inside the fan-shaped material trough. The motion cleaning component includes a comb-shaped scraper, a cleaning brush is provided on the comb-shaped scraper, a rotary drive component is provided on the inner side of the comb-shaped scraper, and an anti-detachment component is telescopically installed on the comb-shaped scraper. A guide seat is provided at the front end of the material rack, and a reciprocating drive mechanism that drives the guide seat to vibrate is installed on the material rack.

[0011] Preferably, the material rack is provided with a slag trough at the bottom of the fan-shaped material trough, and a collection drawer is slidably connected inside the slag trough.

[0012] Preferably, a weighing plate is installed inside the collection drawer, and a pressure sensor is installed between the weighing plate and the collection drawer.

[0013] Preferably, the guide seat is equipped with an electric telescopic rod that pushes the collection drawer to slide, and the telescopic end of the electric telescopic rod is fixedly installed with a flipping component installed on the sliding seat.

[0014] Preferably, the flipping assembly includes a stepper motor and a universal turntable. The universal turntable is installed between the collection drawer and the sliding base and is used to support the rotation of the collection drawer. The stepper motor is installed on the sliding base and its drive shaft is fixedly connected to the collection drawer. The stepper motor drives the collection drawer to rotate.

[0015] Preferably, the rotary drive assembly includes a shaft and several friction rollers fixedly mounted on the shaft. The friction rollers are evenly spaced and located in the gaps between the comb-shaped scrapers. A servo motor is mounted on one end of the shaft.

[0016] Preferably, the anti-detachment component includes an arc-shaped claw plate with comb teeth, with levers fixedly connected to both ends of the arc-shaped claw plate. The levers are set on the radius of the arc-shaped claw plate, and the comb teeth of the arc-shaped claw plate are sleeved inside the comb-shaped scraper. A control motor is fixedly installed on the guide seat, and the rotating shaft of the control motor is fixedly connected to the levers and coincides with the axis of the arc-shaped claw plate.

[0017] Preferably, the reciprocating drive mechanism includes a cam and a drive motor that drives the cam to rotate. The sliding seat is laterally slidably connected inside the material rack.

[0019] Preferably, the sliding seat is provided with a drainage hole below the comb-shaped scraper, and the collection drawer is located below the sliding seat.

[0020] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0021] In this utility model's billet forging feeding mechanism, a working platform supports the entire device and pushes the material rack to slide via a hydraulic pusher, achieving precise billet positioning. A fan-shaped trough at the front of the material rack secures the cylindrical billet and is equipped with a motion cleaning assembly, including a comb-shaped scraper, a cleaning brush, and a rotary drive assembly, effectively removing oxide scale from the billet surface. The scale trough at the bottom of the fan-shaped trough, through the reciprocating vibration of the guide seat, causes the billet to axially reciprocate on the comb-shaped scraper, thus more thoroughly removing oxide scale. Oxide scale debris falls through the gaps in the comb-shaped scraper into the collection drawer of the scale trough. An electric telescopic rod pushes the collection drawer out for cleaning, and a stepper motor drives a tilting assembly to dump the collected oxide scale debris. A control motor mounted on the guide seat drives the arc-shaped claw plate in the anti-detachment assembly to rotate, ensuring the billet is fixed and does not slip after entering the comb-shaped scraper, and is suitable for precision forging billets of different diameters. The sliding seat reciprocates via a cam driven by a drive motor, causing the billet to oscillate axially during rotation, further improving the oxide scale removal effect. Through the cooperation of the above components, this feeding mechanism can achieve efficient and automated billet surface treatment and precise conveying, ensuring the smooth progress of the precision forging process and avoiding material jamming and equipment blockage caused by surface oxide scale.

[0027] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0028] Example 1:

[0029] Please see Figure 1-4 This utility model provides a technical solution:

[0030] A billet forging loading mechanism includes a working platform 1, on which a material rack 2 is provided. The material rack 2 is slidably connected to the upper part of the working platform 1. A hydraulic push rod is provided on the working platform 1 to push the material rack 2 to slide. The pushing mechanism can be a telescopic cylinder or a linear drive slide rail, which drives the material rack 2 to slide linearly on the upper part of the working platform 1, and pushes the billet on the material rack 2 for forging loading.

[0031] The front end of the material rack 2 is provided with a fan-shaped material groove 4, which is used to place cylindrical billets for precision forging. The fan-shaped material groove 4 is equipped with a motion cleaning component. The motion cleaning component dynamically treats the oxide scale on the surface of the billet after high-temperature forging. Compared with the existing billet forging feeding mechanism that relies solely on gravity to clean the oxide scale, it is more efficient and the cleaning is more thorough.

[0032] The motion cleaning component includes a comb-shaped scraper 5, on which a cleaning brush 6 is provided. The cleaning brush 6 can be a wire brush. A rotary drive component is provided inside the comb-shaped scraper 5. The rotary drive component drives the forging blank on the comb-shaped scraper 5 to rotate. The rotating forging blank contacts the cleaning brush 6 on the comb-shaped scraper 5, effectively removing the oxide scale on the surface of the forging blank. An anti-detachment component is telescopically installed on the comb-shaped scraper 5 to prevent the rotating forging blank from detaching from the inside of the comb-shaped scraper 5.

[0033] A guide seat 7 is provided at the front end of the material rack 2. The material rack 2 is equipped with a reciprocating drive mechanism that drives the guide seat 7 to vibrate. The comb-shaped scraper 5, the rotary drive assembly, and the anti-detachment assembly are all installed on the guide seat 7. The reciprocating drive mechanism drives the guide seat 7 to vibrate back and forth at high speed along the axial direction of the fan-shaped material groove 4, so that the billet forging is axially reciprocated on the comb-shaped scraper 5, which is conducive to the thorough removal of oxide scale on the surface of the billet forging. Oxide scale debris falls through the gap of the comb-shaped scraper 5 and is separated from the billet forging. The reciprocating vibration of the guide seat 7 reduces the accumulation of oxide scale debris on the comb-shaped scraper 5 and improves the cleaning efficiency.

[0034] The material rack 2 is located at the bottom of the fan-shaped material trough 4 and has a scale trough 8. A collection drawer 9 is slidably connected inside the scale trough 8. Scale fragments fall into the collection drawer 9 inside the scale trough 8 through the gaps of the comb-shaped scraper 5 for collection and centralized recycling.

[0035] The collection drawer 9 is equipped with a weighing plate 10. A pressure sensor 11 is installed between the weighing plate 10 and the collection drawer 9. The pressure sensor 11 weighs the oxide scale debris on the weighing plate 10. When it reaches a certain weight, it is emptied and cleaned to prevent the inside from accumulating and filling up, which would affect subsequent cleaning work.

[0036] An electric telescopic rod 12 is installed on the guide seat 7 to push the collection drawer 9 to slide. A sliding seat is fixedly installed on the telescopic end of the electric telescopic rod 12. A flipping component is installed on the sliding seat. The electric telescopic rod 12 pushes the collection drawer 9 to the outside of the frame. The sliding seat and the flipping component slide synchronously, making the movement of the collection drawer 9 more stable. The flipping component drives the collection drawer 9 to rotate, pouring out the oxide scale debris collected inside the collection drawer 9.

[0037] The flipping assembly includes a stepper motor 14 and a universal turntable. The universal turntable is installed between the collection drawer 9 and the sliding seat, and it rotatably connects the collection drawer 9 and the sliding seat. The universal turntable is used to support the rotation of the collection drawer 9. The stepper motor 14 is installed on the sliding seat, and the drive shaft of the stepper motor 14 is fixedly connected to the collection drawer 9. When the collection drawer 9 extends outside the frame, the stepper motor 14 drives the collection drawer 9 to rotate, emptying the oxide scale debris collected inside the collection drawer 9.

[0038] The rotary drive assembly includes a shaft 16 and several friction rollers 17 fixedly mounted on the shaft 16. The friction rollers 17 are evenly spaced and located in the gaps of the comb-shaped scraper 5. A servo motor 18 is mounted on one end of the shaft 16. The servo motor 18 drives the shaft 16 to rotate, and the shaft 16 drives the multiple friction rollers 17 to rotate synchronously. The friction rollers 17 use friction to drive the columnar billet to rotate.

[0039] The anti-detachment component includes an arc-shaped claw plate 19 with comb teeth. Two levers 20 are fixedly connected to both ends of the arc-shaped claw plate 19. The levers 20 are positioned on the radius of the arc-shaped claw plate 19. The comb teeth of the arc-shaped claw plate 19 are sleeved inside the comb-shaped scraper 5. A control motor 21 is fixedly mounted on the guide seat 7. The rotating shaft of the control motor 21 is fixedly connected to the levers 20 and coincides with the axis of the arc-shaped claw plate 19. The control motor 21 drives the levers 20 to rotate. The arc-shaped claw plate 19 with comb teeth is rotated, and the billet is placed in front of the comb-shaped scraper 5. The comb teeth of the arc-shaped claw plate 19 are retracted into the comb-shaped scraper 5. The upper part of the comb-shaped scraper 5 is open, which makes it easy for the billet to be placed on the comb-shaped scraper. Then, the motor 21 is controlled to drive the lever 20 to rotate. The comb teeth of the arc-shaped claw plate 19 extend out from the inside of the comb-shaped scraper 5. The arc-shaped claw plate 19 closes the upper part of the comb-shaped scraper 5, thereby preventing the rotating billet from falling off the comb-shaped scraper 5.

[0040] Example 2:

[0041] Please see Figure 1-4Furthermore, in conjunction with Embodiment 1, the reciprocating drive mechanism includes a cam 22 and a drive motor 23 that drives the cam 22 to rotate. A sliding seat is laterally slidably connected inside the material rack 2. Guide posts 24 are fixedly connected to both ends of the sliding seat, and the guide posts 24 are slidably sleeved on the side wall of the material rack 2. The cam 22 is located outside one of the guide posts 24. The drive motor 23 is fixedly installed on the outside of the material rack 2. A return spring 25 is sleeved on the outside of the other guide post 24, and the return spring 25 is located between the sliding seat and the inner wall of the material rack 2.

[0042] The cam 22 is driven to rotate by the drive motor 23. The protruding part of the cam 22 pushes the guide post 24 on the sliding seat, so that the sliding seat slides along the axis of the fan-shaped material groove 4, that is, the axial direction of the billet forging. When the non-protruding part of the cam 22 rotates to the position of the guide post 24, the return spring 25 pushes the sliding seat to slide in the opposite direction. The above steps are repeated to realize the reciprocating movement of the sliding seat, so that the billet forging slides axially relative to the comb-shaped scraper 5 with the cleaning brush 6, thereby completely removing the oxide scale on the rotating billet forging surface.

[0043] The sliding seat is located below the comb-shaped scraper 5 and has a drainage hole. The collection drawer 9 is located below the sliding seat, and the oxide scale debris falls into the collection drawer 9 through the drainage hole.

[0044] The working principle of the billet forging feeding mechanism is as follows:

[0045] During operation, the cylindrical billet is placed in the fan-shaped trough 4 at the front end of the material rack 2. At this time, the arc-shaped claw plate 19 of the anti-detachment component is in a retracted state, facilitating the smooth placement of the billet into the comb-shaped scraper 5. Subsequently, the control motor 21 drives the lever 20 to rotate, causing the comb teeth of the arc-shaped claw plate 19 to extend and close the upper part of the comb-shaped scraper 5, preventing the billet from falling off. The servo motor 18 starts, driving the friction roller 17 to rotate via the shaft 16. The friction force causes the billet to rotate within the comb-shaped scraper 5, while the cleaning brush 6 scrapes the surface of the billet. At the same time, the drive motor 23 drives the cam 22 to rotate, which, in conjunction with the return spring 25, pushes the guide seat 7 to reciprocate at high speed along the axis of the billet, causing the billet to sway axially during rotation, thereby more thoroughly removing the oxide scale. The detached oxide scale debris falls through the gaps in the comb-shaped scraper 5 and enters the collection drawer 9 of the scale trough 8 through the drainage holes at the bottom of the guide seat 7. When the pressure sensor 11 detects that the debris on the weighing plate 10 has reached the set weight, the electric telescopic rod 12 pushes the collection drawer 9 out, and the stepper motor 14 drives the drawer to flip over via the universal turntable, realizing automatic tilting. The cleaned billet is pushed by the pushing mechanism to slide the material rack 2, and the billet is transported to the precision forging station, realizing efficient and continuous automated feeding and surface treatment.

[0046] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
