Description

Technical Field

[0001] This utility model relates to the field of machining technology, and more specifically, to a forging blank transfer device. Background Technology

[0002] The content in this section only provides background information related to this utility model and may not constitute prior art.

[0003] In the forging and machining of metal fittings such as valves and flanges, it is often necessary to transfer cylindrical forging blanks between the storage station and the feeding station of the machining equipment. Since the feeding ports of some machining equipment (such as forging presses and CNC machine tools) are usually high, while the blank storage area is usually set low for ease of manual operation, a special transfer mechanism is required to lift the blanks from the low position to the high position.

[0004] In related technologies, a utility model patent with authorization announcement number CN210236974U discloses a valve accessory blank transfer mechanism. This mechanism uses a lifting motor to drive the transfer trough to rise and fall, and uses a lifting bar fixed at its feeding end to lift and raise the blank in the storage trough, and finally send it to the feeding trough to realize the feeding.

[0005] While this solution improves the convenience of billet transfer to some extent, practical experience has revealed a significant drawback: the lifting bars on the transfer trough are fixed and always extended. This causes spatial interference between the extended lifting bars and billets in the storage tank during the descent and resetting process after a lifting operation. To avoid this interference, operators must place only one billet in the storage tank at a time, manually adding the next billet only after it has been transferred. This prevents continuous autonomous billet transfer, thus limiting overall production efficiency. Summary of the Invention

[0023] Please refer to Figures 1 to 7 The present invention provides a forging blank transfer device.

[0024] According to embodiments of the present invention, such as Figure 1 As shown, the forging blank transfer device includes a feeding trough 10, a transfer trough 20, and a storage trough 30 arranged obliquely from left to right. In this embodiment, the higher end of the feeding trough 10, the transfer trough 20, and the storage trough 30 are their respective feeding ends, and the lower end is their respective discharging end.

[0025] The feed trough 10 is positioned higher than the storage trough 30 and is fixedly mounted on the first frame 40. The discharge end of the feed trough 10 connects to the inlet of processing equipment (such as a forging press). The storage trough 30 is positioned lower than the feed trough 10 and is fixedly mounted on the second frame 50. Figure 2 As shown, the discharge end of the storage tank 30 is equipped with a baffle 31 and a discharge port 32.

[0026] like Figure 1 As shown, the transfer trough 20 is connected to a lifting mechanism 80, which allows it to move up and down between the storage trough 30 and the feed trough 10 under the drive of the lifting mechanism 80, so as to transfer the blank material.

[0027] The forging billet transfer device provided in this embodiment of the present invention transfers billets in a manner that is essentially consistent with the transfer method disclosed in patent document CN210236974U. One of the core improvements of this embodiment of the present invention lies in the feed end of the transfer groove 20.

[0028] Specifically, such as Figures 2 to 4 As shown, a lifting bar 60 is rotatably mounted on the feed end of the transfer trough 20 via a first rotating shaft 61, that is, the lifting bar 60 can rotate around the axis of the first rotating shaft 61.

[0029] In addition, the forging blank transfer device provided in this embodiment of the present invention also includes a first driving mechanism. The first driving mechanism can be disposed on the transfer groove 20 and is used to drive the lifting bar 60 to rotate around the axis of the first rotating shaft 61 between the avoidance station and the lifting station.

[0030] In a preferred embodiment of this invention, such as Figure 5 As shown, the first drive mechanism may include a first servo motor 62 fixedly installed on the outer wall of the transfer trough 20. The output end of the first servo motor 62 is connected to the first rotating shaft 61 for transmission. By using a servo motor to drive the lifting bar 60 to rotate, it is beneficial to accurately control the rotation position of the lifting bar 60. Based on the small size of the servo motor and its ability to output sufficiently large torque, the reliability of the lifting bar 60 during rotation can be improved while ensuring a compact structure, so that the lifting bar 60 can be accurately rotated to the predetermined work position and has a large load-bearing capacity.

[0031] Among them, the two key stations of the lifting bar 60 during rotation are the aforementioned avoidance station and lifting station. For example... Figure 1 or Figure 2As shown, when the lifting bar 60 is in the avoidance position, the lifting bar 60 forms an angle with the conveying surface of the transfer trough 20. For example, the lifting bar 60 rotates downward relative to the transfer trough 20 to a position below the transfer trough 20 and is in an inclined state. In this state, if the transfer trough 20 descends from a position higher than the storage trough 30, the lifting bar 60 can avoid the storage trough 30, thereby allowing the transfer trough 20 to descend smoothly to a position lower than the storage trough 30.

[0032] like Figure 3 As shown, when the lifting bar 60 is in the lifting position, the upper surface of the lifting bar 60 and the conveying surface of the transfer trough 20 form a continuous first conveying plane. In this state, if the transfer trough 20 rises from a position lower than the storage trough 30, the free end of the lifting bar 60 can pass through the lifting port 32 on the storage trough 30, so that the transfer trough 20 can rise smoothly to a position higher than the storage trough 30.

[0033] According to an embodiment of this utility model, the working process of the forging blank transfer device is as follows: Assuming that in the initial state, the transfer trough 20 is located at a low position below the storage trough 30. The operator can pre-place multiple blanks into the inclined storage trough 30. Under the action of gravity, the multiple blanks slide along the storage trough 30 and are arranged in close succession. The blank at the foremost position is blocked by the baffle 31 at the discharge port 32.

[0034] Step 1: Control the first servo motor 62 to rotate the lifting bar 60 to the lifting position. Then, activate the lifting mechanism 80 to drive the transfer trough 20 upwards. During this process, the free end of the lifting bar 60 passes through the lifting port 32, smoothly lifting the first blank at the front of the storage trough 30. As the transfer trough 20 continues to rise, the first blank will eventually roll from the lifting bar 60 into the transfer trough 20 under gravity. The transfer trough 20 can then carry the first blank further upwards to complete the transfer of the first blank to the feed trough 10.

[0035] Step 2: After the transfer trough 20 completes the transfer of the first blank to the feed trough 10, the first servo motor 62 drives the lifting bar 60 to rotate to the clearance position. Subsequently, the lifting mechanism 80 drives the transfer trough 20 to descend. Since the lifting bar 60 has been retracted, the descent process will not interfere with the storage trough 30 or the blank inside the storage trough 30. The transfer trough 20 returns to its low position, ready for the next operation.

[0036] Meanwhile, after the first blank is removed, the remaining blank in the storage tank 30 automatically rolls forward one station under the action of gravity, and the next blank is replenished to the transfer position at the baffle 31.

[0037] By repeating the first and second steps above, multiple blanks in the storage tank 30 can be sequentially and continuously transferred to the feed tank 10 as needed, without the need for manual replenishment of new blanks to the storage tank 30.

[0038] The forging billet transfer device provided in this embodiment, by designing the lifting bar 60 to rotate between the avoidance station and the lifting station, allows the transfer trough 20 to effectively avoid the storage trough 30 when descending, thereby allowing multiple billets to be pre-stored in the storage trough 30 and automatically replenished, completely eliminating the bottleneck of needing continuous manual feeding, effectively solving the technical problem that existing transfer mechanisms cannot achieve continuous autonomous transfer of billets, and is conducive to improving overall production efficiency.

[0039] Additionally, as the transfer trough 20 carries the billet upwards, the first drive mechanism can also drive the lifting bar 60 to rotate upwards relative to the transfer trough 20 (e.g., Figure 6 As shown in the figure, this forms a barrier at the feed end of the transfer trough 20 to reduce the risk of the blank falling from the feed end of the transfer trough 20 under abnormal conditions, thereby further improving the reliability of the transfer trough 20 when transferring blanks.

[0040] According to embodiments of the present invention, such as Figure 5 As shown, the free end of the lifting bar 60 has an arc-shaped structure. Since the free end of the lifting bar 60 may come into contact with the outer wall of the next blank when it lifts the foremost blank in the storage tank 30, the arc-shaped structure helps to reduce the friction when the free end of the lifting bar 60 comes into contact with the outer wall of the next blank, thereby reducing the resistance encountered by the lifting bar 60 in lifting the current blank and avoiding jamming as much as possible.

[0041] According to the embodiments of this utility model, continue to refer to Figure 5 As shown, a buffer anti-slip pad 63 can also be provided on the upper surface of the lifting bar 60. The buffer anti-slip pad 63 can be made of rubber or polyurethane. The buffer anti-slip pad 63 serves two purposes: first, it increases the friction between the billet and the lifting bar 60, preventing the billet from slipping when rolling on the lifting bar 60; second, it reduces the impact of the lifting bar 60 on the billet at the moment when it contacts the billet in preparation for lifting the billet, thereby protecting the billet.

[0042] According to the embodiments of this utility model, in the existing transfer mechanism disclosed in the patent document with authorization announcement number CN210236974U, the blank in the transfer trough 20 is automatically transferred to the feed trough 10 by a passive feeding mechanism consisting of a limiting post and an elastic element set at the discharge end of the transfer trough 20. The reliability of this design depends heavily on the precise alignment of the transfer trough 20 and the feed trough 10, and there is a risk of jamming or damage to the mechanism due to alignment deviation. At the same time, the mechanical linkage structure is complex and the elastic element is prone to fatigue, and the feeding process is completely passive and uncontrollable.

[0043] Therefore, the forging blank transfer device provided in the embodiments of this utility model has also improved the structure of the discharge end of the transfer trough 20.

[0044] Specifically, such as Figures 2 to 4 As shown, a limiting plate 70 is rotatably mounted on the discharge end of the transfer trough 20 via a second rotating shaft 71.

[0045] In addition, the forging blank transfer device provided in this embodiment of the present invention also includes a second drive mechanism. The second drive mechanism can be disposed on the transfer groove 20 and is used to drive the limiting plate 70 to rotate around the axis of the second rotating shaft 71 between the blocking station and the unloading station.

[0046] In a preferred embodiment of this invention, such as Figure 5 As shown, the second drive mechanism may include a second servo motor 72 fixedly mounted on the outer wall of the transfer groove 20. The output end of the second servo motor 72 is connected to the second rotating shaft 71 for transmission. By using a servo motor to drive the limit plate 70 to rotate, it is also beneficial to accurately control the rotation position of the limit plate 70. Based on the small size of the servo motor and its ability to output sufficiently large torque, the limit plate 70 can be reliably held in the predetermined position while ensuring a compact structure.

[0047] Among them, such as Figure 5 As shown, when the limiting plate 70 is in the blocking position, the limiting plate 70 forms a barrier at the discharge end of the transfer trough 20 to prevent the blank material in the transfer trough 20 from moving out of the discharge end of the transfer trough 20. Figure 6 As shown, when the limiting plate 70 is in the feeding position, the upper surface of the limiting plate 70 and the conveying surface of the transfer trough 20 form a continuous second conveying plane, so that the blank in the transfer trough 20 can enter the feeding trough 10 along the second conveying plane.

[0048] Specifically, during the process of the transfer trough 20 rising to transfer the blank, the limiting plate 70 is always in the blocking position to prevent the blank in the transfer trough 20 from moving out of the discharge end of the transfer trough 20. After the transfer trough 20 rises to the point where its discharge end is basically aligned with the feed end of the feed trough 10, the second servo motor 72 drives the limiting plate 70 to rotate to the unloading position. At this time, the second conveying plane is seamlessly connected with the conveying surface of the feed trough 10, and the blank in the transfer trough 20 can enter the feed trough 10 under the action of gravity to complete the automatic feeding operation.

[0049] Understandably, by constructing the limit plate 70 in a form that can rotate under the drive of the second drive mechanism, automatic feeding is achieved while completely eliminating the complex mechanical linkage structure that relies on precision alignment and elastic elements. This fundamentally eliminates the risk of failure caused by jamming or fatigue and also enables active control over the feeding timing.

[0050] According to embodiments of the present invention, such as Figure 7 As shown, the feed end of the transfer trough 20 is provided with an inwardly recessed first mounting port 21; the discharge end of the transfer trough 20 is provided with an inwardly recessed second mounting port 22. The lifting strip 60 is installed in the first mounting port 21; the limiting plate 70 is installed in the second mounting port 22.

[0051] By setting two installation ports to install the lifting bar 60 and the limiting plate 70 respectively, the two can be strictly flush with the conveying surface of the transfer trough 20 when they are in their respective working positions. At the mechanical structure level, this ensures the true continuity and smoothness between the first and second conveying planes, and minimizes the transfer problems, abnormal postures or surface damage caused by jumping, jamming or scraping of the blank at the transition joint.

[0052] According to an embodiment of the present invention, the lifting mechanism 80 used to drive the transfer trough 20 to rise and fall can specifically be a screw drive mechanism.

[0053] Specifically, refer to Figure 1 As shown, the lead screw transmission mechanism includes a drive motor 81, a movable seat 82, a lead screw 83, and a guide rail 84. The drive motor 81 can be fixedly mounted on the first frame 40. The movable seat 82 is connected to the bottom of the transfer trough 20 to support the transfer trough 20.

[0054] One end of the lead screw 83 is connected to the drive motor 81, enabling it to rotate around its own axis under the drive of the drive motor 81. The other end of the lead screw 83 extends along the lifting path of the transfer groove 20 and passes through the movable seat 82. The movable seat 82 and the lead screw 83 are threaded together.

[0055] The guide rail 84 extends along the lifting path of the transfer groove 20 and is fixedly mounted on the first frame 40. The movable seat 82 is slidably connected to the guide rail 84.

[0056] With the above settings, when the drive motor 81 drives the lead screw 83 to rotate, based on the thread transmission principle, the moving seat 82 will drive the transfer groove 20 to move along the axial direction of the lead screw 83, so as to realize the lifting and lowering of the transfer groove 20.

[0057] Using a screw drive mechanism as the lifting mechanism 80 not only provides high-precision positioning for the vertical movement of the transfer trough 20, ensuring accurate and stable alignment when connected with the storage trough 30 and the feed trough 10, but also utilizes the inherent self-locking characteristics of the screw drive to effectively prevent the transfer trough 20 from accidentally sliding down in the event of a power outage or when stationary. This improves operational reliability and safety, while laying a solid power and control foundation for achieving fully automatic continuous feeding.

[0058] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
