Description

Technical Field

[0001] This invention relates to the field of steel ball processing equipment technology, specifically to a station transfer device for steel ball forging. Background Technology

[0002] Steel balls are the grinding media used in ball mill equipment for grinding materials.

[0003] In the process of processing steel balls, firstly, the cylindrical steel billet is fed into the heating equipment for heating; then, the steel billet is transferred to the forging equipment by the feeding conveyor, and the forging equipment forges the steel billet into steel balls; finally, the steel balls are sent to the heat treatment process by the discharge conveyor.

[0004] At the forging equipment, forming dies and trimming dies are required.

[0005] The forming die includes an upper forming die and a lower forming die. The upper forming die is fixedly installed on the punch of the forging equipment, and the lower forming die is fixedly installed on the worktable of the forging equipment. The punch drives the upper forming die to press downward, forging the columnar steel billet into a spherical shape. During the deformation process, the columnar steel billet overflows from the parting surface between the upper forming die and the lower forming die to form a flash, resulting in a steel ball with flash.

[0006] The trimming die includes an upper trimming die and a lower trimming die. The upper trimming die is fixedly installed on the punch of the forging equipment, and the lower trimming die is fixedly installed on the worktable of the forging equipment. The punch drives the upper trimming die to press downwards, and the steel ball with flash is removed by the punching action of the upper and lower trimming dies.

[0007] When feeding steel billets from the feeding conveyor to the forming die, transferring steel balls from the forming die to the trimming die, and discharging steel balls from the trimming die to the discharge conveyor, all operations require manual operation by workers using pliers. In other words, the transfer processes from the feeding station to the forming station, from the forming station to the trimming station, and from the trimming station to the discharge station all rely on manual operation, resulting in time-consuming, labor-intensive, and highly dangerous processes. Summary of the Invention

[0008] To address the aforementioned shortcomings of existing technologies, this invention provides a station transfer device for steel ball forging. This invention enables mechanized material replenishment, transfer, and unloading operations, eliminating the need for manual labor and saving time and effort while improving safety. To achieve the above objectives, the present invention provides the following technical solution: A station transfer device for steel ball forging includes a worktable. The top surface of the worktable is provided with a forming lower die and a trimming lower die. The side of the forming lower die is provided with a feeding track, and the side of the trimming lower die is provided with a discharge track. The end of the feeding track, the forming lower die, the trimming lower die and the beginning of the discharge track are on the same horizontal straight line. Both the forming lower die and the trimming lower die are equipped with a lifting mechanism, which is used to lift the steel ball upwards. The workbench is provided with a clamping mechanism and two clamps. The clamping mechanism is used to drive the two clamps to move closer or further apart in the longitudinal direction. Each of the two clamps is provided with a cylindrical groove, a first spherical groove, and a second spherical groove on the side facing each other. The workbench is also equipped with a transverse movement mechanism, which is used to drive the clamping mechanism to move laterally.

[0009] Furthermore, the clamping mechanism includes two clamping seats and a clamping drive. Both clamping seats are slidably connected to the worktable along the longitudinal direction. One clamping seat is provided with a clamp. The clamping drive is located on the worktable and is used to drive the clamping seat to move along the longitudinal direction.

[0010] Furthermore, the transverse movement mechanism includes a transverse movement seat, a slide rod, and a transverse telescopic rod. The transverse movement seat is slidably connected to the clamping seat in the transverse direction. The clamp is provided on the transverse movement seat. The slide rod is also provided on the transverse movement seat. The slide rod extends in the longitudinal direction. The transverse telescopic rod is provided on the worktable. The output end of the transverse telescopic rod extends and retracts in the transverse direction. The output end of the transverse telescopic rod is slidably connected to the slide rod in the longitudinal direction.

[0011] Furthermore, the lifting mechanism includes a lifting column, a lifting connecting rod, a lifting seat, and a lifting elastic element; Both the forming lower die and the trimming lower die have lifting cavities inside, and lifting columns are provided in the lifting cavities. The lifting columns slide vertically with the lifting cavities. Both the forming lower die and the trimming lower die have driving cavities on their sides. The driving cavities are connected to the lifting cavities. The driving cavities are equipped with lifting connecting rods. The top end of the lifting connecting rods is rotatably connected to the bottom part of the lifting column, and the bottom end of the lifting connecting rods is rotatably connected to the lifting seat. The lifting seat is slidably connected to the worktable along the longitudinal direction, and the clamping seat abuts against the lifting seat on the side close to the forming lower die and the trimming lower die; The lifting elastic element is located on the worktable and is used to push the lifting seat to maintain its contact with the clamping seat.

[0012] Furthermore, the top surface of the workbench is provided with a dovetail groove that extends longitudinally, and the bottom of the lifting seat is provided with a lifting slider that slides longitudinally with the dovetail groove.

[0013] Furthermore, the bottom of the clamping seat is provided with a clamping slider, which slides longitudinally with the dovetail groove.

[0014] Furthermore, it also includes a shielding mechanism, which includes a baffle, a shielding elastic element, a shielding connecting rod, and a shielding seat. The end of the feeding track and the beginning of the discharging track are both provided with movable grooves, and a baffle is provided in the movable groove. The baffle and the movable groove are vertically slidably engaged. The end of the feeding track and the beginning of the discharging track are both connected to the bottom of the baffle through the shielding elastic element. The shielding elastic element is used to pull the baffle upward. The bottom of the baffle is rotatably connected to the bottom of the shielding connecting rod, and the top of the shielding connecting rod is rotatably connected to the top of the shielding seat. The shielding seat is provided on the lifting seat.

[0015] Furthermore, the starting end of the feeding track is higher than the ending end of the feeding track, and the starting end of the feeding track abuts against the conveying end of the feeding conveyor.

[0016] Furthermore, the starting end of the discharge track is higher than the ending end of the discharge track, and the ending end of the discharge track abuts against the discharge conveyor.

[0017] Furthermore, the forming lower mold and the trimming lower mold are an integral structure.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The lifting mechanism can eject the steel balls from the forming lower die and the trimming lower die; the clamping mechanism can drive the two clamps to move closer to each other and clamp the steel billet in the feeding track, the steel ball ejected by the lifting mechanism in the forming lower die and the trimming lower die; the lateral movement mechanism can drive the clamps to move the steel billet and steel balls laterally; when the clamping mechanism drives the two clamps to separate, the steel billet and steel balls can be released to the current position.

[0019] Therefore, this device can complete the feeding operation of steel billets from the feeding track to the forming lower die, the transfer operation of steel balls with flash from the forming lower die to the trimming lower die, and the discharge operation of steel balls with flash removed from the trimming lower die to the discharge track. That is, this device realizes the transfer process from the feeding station to the forming station, from the forming station to the trimming station, and from the trimming station to the discharge station.

[0020] In summary, this device enables mechanized feeding, transfer, and discharging operations, eliminating the need for manual labor and saving time and effort while improving safety. 2. By using a cylindrical groove to hold the cylindrical steel billet and a first spherical groove and a second spherical groove to hold the steel ball, the shape of the steel billet and the steel ball can be better matched, which can reduce the risk of the steel billet and the steel ball falling, improve the clamping reliability, and improve the reliability of the device in transfer operations.

[0021] 3. Because the lifting mechanism ejects the steel balls from the forming lower die and the trimming lower die, and the clamping mechanism clamps the ejected steel balls, the clamping mechanism can clamp the thickest part of the steel ball in the vertical direction, which can further improve the clamping reliability, further reduce the risk of the steel balls falling off, and further improve the reliability of the device in transfer operations.

[0022] 4. When the lifting column in the lifting mechanism does not lift the steel ball, the lifting column rests on the top surface of the worktable, so that the lifting column can withstand the impact force during forging and ensure the reliability of the forging operation.

[0023] 5. The lifting mechanism can be linked with the clamping mechanism. When the two clamping seats in the clamping mechanism approach each other, they can push the lifting seat in the lifting mechanism closer to the forming lower die and the trimming lower die, causing the lifting column in the lifting mechanism to eject the steel balls in the forming lower die and the trimming lower die. Conversely, when the two clamping seats move away from each other, the lifting seat in the lifting mechanism can be allowed to leave the forming lower die and the trimming lower die, causing the lifting column to fall back to its original position. No additional power source is needed to drive the lifting column's movement, which helps save energy and reduce costs. Furthermore, the synchronous operation of the lifting mechanism and the clamping mechanism improves adjustment efficiency.

[0024] 6. By setting up a shielding mechanism, when there is no need to transfer the billet and steel ball, the baffle can be used to shield the end of the feeding track and the beginning of the discharge track, so that the billet in the feeding track will not accidentally enter the forming lower die, and the steel ball in the discharge track will not accidentally enter the trimming lower die, which helps to improve the reliability of the entire device.

[0025] 7. The blocking mechanism can be linked with the lifting mechanism. When the lifting column in the lifting mechanism lifts the steel balls in the forming lower die and the trimming lower die, the baffle in the blocking mechanism moves down to open the feeding track and the discharging track, ensuring that the billet and steel balls can be smoothly transferred. Conversely, when the lifting column in the lifting mechanism falls back down, the baffle in the blocking mechanism moves up to block the feeding track and the discharging track again, ensuring that the billet in the feeding track will not accidentally enter the forming lower die during the forging process, and that the steel balls in the discharging track will not accidentally enter the trimming lower die. No additional power source is needed to drive the baffle to move up and down, which is beneficial for energy saving and cost reduction. Furthermore, the blocking mechanism and the lifting mechanism can move synchronously through linkage, improving adjustment efficiency.

[0026] 8. When the forming lower mold and the trimming lower mold are integrated into one structure, the number of molds can be reduced, making it easier to disassemble and assemble on the worktable and improving disassembly and assembly efficiency; in addition, the overall structure can be made more compact, which is conducive to improving space utilization.

Detailed Implementation

[0029] 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] Example 1: See Figures 1 to 18 A station transfer device for steel ball forging includes a worktable 1, a forming lower die 2, a trimming lower die 3, a feeding track 4, a discharging track 5, a lifting mechanism 6, two clamps 7, a clamping mechanism 8, and a transverse movement mechanism 9.

[0031] The workbench 1 is a structure in forging equipment (such as a press or air hammer) used to support the forming die 2 and the trimming die 3.

[0032] The forming lower die 2 is the lower die in the forming mold, and the trimming lower die 3 is the lower die in the trimming mold. Both the forming lower die 2 and the trimming lower die 3 are fixedly installed on the top surface of the worktable 1. This device is used to forge steel balls 30, so the cavity of the forming lower die 2 is a hemispherical cavity, and the cavity of the trimming lower die 3 is also a hemispherical cavity.

[0033] The forming die includes a lower forming die 2 and an upper forming die, while the trimming die includes a lower trimming die 3 and an upper trimming die. Both the upper forming die and the upper trimming die are fixedly mounted on the punch of the forging equipment. When the punch of the forging equipment carries the upper forming die and the upper trimming die downwards, the upper forming die cooperates with the lower forming die 2 to forge the cylindrical steel billet 20 into a steel ball 30. During the extrusion process, the steel billet 20 is extruded from between the parting surfaces of the upper forming die and the lower forming die 2, forming a flash 301. The upper trimming die cooperates with the lower trimming die 3 to remove the flash 301 from the steel ball 30. Figure 5 The image shown is a three-dimensional view of a steel billet 20, a steel ball 30 with flash, and a steel ball 30 with flash removed.

[0034] The forming lower mold 2 and the trimming lower mold 3 are separate molds. Alternatively, the forming lower mold 2 and the trimming lower mold 3 are a single integrated structure. Figure 1 The diagram shows the state when the forming lower die 2 and the trimming lower die 3 are an integral structure. When the forming lower die 2 and the trimming lower die 3 are an integral structure, the forming upper die and the trimming upper die are also an integral structure mounted on the punch to match them. When the forming lower die 2 and the trimming lower die 3 are an integral structure, the number of dies can be reduced, facilitating assembly and disassembly on the worktable 1 and improving assembly and disassembly efficiency; furthermore, the overall structure is more compact, which is beneficial for improving space utilization.

[0035] See Figure 1 The lower forming die 2 is provided with a feeding track 4 on the side away from the lower cutting die 3. The feeding track 4 is fixedly installed on the top surface of the worktable 1. The starting end of the feeding track 4 is higher than the ending end of the feeding track 4. The starting end of the feeding track 4 abuts against the end of the feeding conveyor. The feeding conveyor can be a belt conveyor, chain conveyor, or other equipment. The ending end of the feeding track 4 abuts against the side of the lower forming die 2.

[0036] When the feeding conveyor transports the cylindrical steel billet 20 to the end of the feeding conveyor, the steel billet 20 slides into the beginning of the feeding track 4 under the action of transmission inertia, and slides down to the end of the feeding track 4 along the inclined direction of the feeding track 4.

[0037] See Figure 1 The trimming die 3 has a discharge track 5 on the side away from the forming die 2. The discharge track 5 is fixedly installed on the top surface of the worktable 1. The starting end of the discharge track 5 is higher than the ending end of the discharge track 5. The starting end of the discharge track 5 abuts against the side of the trimming die 3, and the ending end of the discharge track 5 abuts against the discharge conveyor. The discharge conveyor can also be a belt conveyor, chain conveyor, or other equipment.

[0038] When the steel ball 30 enters the discharge track 5, the steel ball 30 rolls along the inclined direction of the discharge track 5 onto the discharge conveyor, which then transports the steel ball 30 to the subsequent process (such as the quenching process).

[0039] See Figure 2 The end of the feeding track 4, the lower forming die 2, the lower trimming die 3, and the beginning of the discharge track 5 are all on the same horizontal straight line. This arrangement facilitates the subsequent use of the clamp 7 to clamp and move the billet 20 and the steel ball 30 together.

[0040] Both the lower forming die 2 and the lower trimming die 3 are equipped with lifting mechanisms 6, which are used to lift the steel ball 30 upwards.

[0041] See Figures 6 to 10 The lifting mechanism 6 includes a lifting column 61, a lifting connecting rod 62, a lifting seat 63, and a lifting elastic element 64. Both the forming lower mold 2 and the trimming lower mold 3 have lifting cavities 611 inside, with the lifting column 61 inside each cavity. The lifting column 61 slides vertically into the lifting cavity 611. Both the forming lower mold 2 and the trimming lower mold 3 have driving cavities 621 on their sides, which communicate with the lifting cavities 611. The driving cavity 621 contains the lifting connecting rod 62, whose top end is rotatably connected to the lower part of the lifting column 61, and whose bottom end is rotatably connected to the lifting seat 63. The top surface of the worktable 1 has a dovetail groove 11 extending longitudinally. The bottom of the lifting seat 63 has a lifting slider 631, which slides longitudinally into the dovetail groove 11. The lifting elastic element 64 is a spring. The lifting elastic element 64 is located in the dovetail groove 11. One end of the lifting elastic element 64 abuts against the groove wall of the dovetail groove 11, and the other end of the lifting elastic element 64 abuts against the lifting slider 631. The lifting elastic element 64 is used to push the lifting seat 63 to move away from the forming lower mold 2 and the trimming lower mold 3.

[0042] The working principle of the lifting mechanism 6 is as follows: When the lifting seat 63 overcomes the elastic force of the lifting elastic element 64 and approaches the forming lower mold 2 and the trimming lower mold 3, the lifting seat 63 pushes the bottom of the lifting connecting rod 62 to approach the forming lower mold 2 and the trimming lower mold 3, causing the top of the lifting connecting rod 62 to push the lifting column 61 upward, and the lifting column 61 pushes the steel ball 30 inside the forming lower mold 2 or the trimming lower mold 3 upward. Conversely, when the lifting seat 63 moves in the opposite direction under the push of the elastic force of the lifting elastic element 64, the lifting seat 63 drives the bottom of the lifting connecting rod 62 to leave the forming lower mold 2 and the trimming lower mold 3, causing the top of the lifting connecting rod 62 to pull down the lifting column 61, and the lifting column 61 falls back onto the worktable 1.

[0043] In addition, the top surface of the lifting column 61 is a spherical surface, which can match the surface shape of the hemispherical cavity in the forming lower mold 2 and the hemispherical cavity in the trimming lower mold 3, which helps to ensure the processing quality of the steel ball 30 and obtain a spherical steel ball 30.

[0044] See Figure 1 , Figure 2 and Figure 3The two clamps 7 are higher than the top surfaces of the forming lower mold 2 and the trimming lower mold 3, and are located on opposite sides of the forming lower mold 2 and the trimming lower mold 3, respectively. See also Figure 11 Both clamps 7 are provided with a cylindrical groove 71, a first spherical groove 72, and a second spherical groove 73 on the side facing each other. The first spherical groove 72 is provided with a flash groove 721 in the middle.

[0045] See Figure 4 and Figure 11 When the two clamps 7 approach each other longitudinally, the cylindrical groove 71 is used to clamp the steel billet 20 located at the end of the feeding track 4, the first spherical groove 72 is used to clamp the steel ball 30 located in the forming lower die 2, the flash groove 721 is used to avoid the flash 301 on the steel ball 30, and the second spherical groove 73 is used to clamp the steel ball 30 located in the trimming lower die 3. Conversely, when the two clamps 7 move away from each other longitudinally, the two clamps 7 can move away from the top surfaces of the forming lower die 2 and the trimming lower die 3, which can prevent the two clamps 7 from hindering the downward movement of the forming upper die and the trimming upper die.

[0046] By using the cylindrical groove 71 to clamp the cylindrical steel billet 20 and the first spherical groove 72 and the second spherical groove 73 to clamp the steel ball 30, the steel billet 20 and the steel ball 30 can be more closely matched, which can reduce the risk of the steel billet 20 and the steel ball 30 falling off, improve the clamping reliability, and improve the reliability of the device in transfer operations.

[0047] The clamping mechanism 8 is used to drive the two clamps 7 to move closer or further apart along the longitudinal direction.

[0048] See Figure 11 The clamping mechanism 8 includes two clamping seats 81 and a clamping drive member 82. See also Figure 2 The two clamping seats 81 are located on both sides of the forming lower die 2 and the trimming lower die 3, respectively; see Figure 11 The bottom of the clamping base 81 is provided with a clamping slider 811, and the clamping slider 811 and the clamping base 81 are an integral structure; see Figure 1 The clamping slider 811 slides longitudinally with the dovetail groove 11. The clamping seat 81 abuts against the lifting seat 63 on the side close to the forming lower mold 2 and the trimming lower mold 3. A clamping fixture 7 is provided on one clamping seat 81. Both clamping seats 81 are provided with clamping drive members 82 on the side opposite to each other. The clamping drive members 82 are hydraulic cylinders, pneumatic cylinders or electric cylinders. The clamping drive members 82 are fixedly installed on the worktable 1. The output end of the clamping drive members 82 extends and retracts longitudinally. The output end of the clamping drive members 82 is fixedly installed with the clamping seat 81.

[0049] The working principle of the clamping mechanism 8 is as follows: when the output ends of the two clamping drive members 82 are extended, the two clamping drive members 82 push the two clamping seats 81 closer to the forming lower die 2 and the trimming lower die 3. The two clamping seats 81 drive the two clamps 7 to move closer to each other, so that the two clamps 7 clamp the steel billet 20 and the steel ball 30. Conversely, when the output ends of the two clamping drive members 82 are retracted, the two clamping drive members 82 drive the two clamping seats 81 away from the forming lower die 2 and the trimming lower die 3. The two clamping seats 81 drive the two clamps 7 to move away from each other, releasing the steel billet 20 and the steel ball 30.

[0050] Furthermore, when the clamping mechanism 8 drives the two clamping seats 81 to approach each other, the two clamping seats 81 overcome the elastic force of the lifting elastic member 64 and push the two lifting seats 63 to approach each other, so that the lifting column 61 lifts the steel ball 30 in the forming lower mold 2 and the trimming lower mold 3, so that the two clamps 7 can smoothly clamp the steel ball 30 lifted from the forming lower mold 2 and the trimming lower mold 3; conversely, when the clamping mechanism 8 drives the two clamping seats 81 to move away from each other, the two lifting seats 63 move away from each other under the push of the lifting elastic member 64, so that the lifting column 61 falls back to its original position.

[0051] The lateral movement mechanism 9 is used to drive the clamping mechanism 8 to move laterally.

[0052] See Figure 11 The transverse movement mechanism 9 includes a transverse movement seat 91, a slide rod 92, and a transverse telescopic rod 93. The transverse movement seat 91 is slidably connected to the clamping seat 81 in the transverse direction. A clamp 7 is fixedly mounted on the transverse movement seat 91. The slide rod 92 is also fixedly mounted on the transverse movement seat 91, extending longitudinally. The transverse telescopic rod 93 is fixedly mounted on the worktable 1. The transverse telescopic rod 93 can be a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder. The output end of the transverse telescopic rod 93 extends and retracts laterally. (See also...) Figure 11 The output end of the transverse telescopic rod 93 is provided with a sliding hole 931, and the sliding hole 931 and the sliding rod 92 slide in a longitudinal direction.

[0053] The working principle of the transverse movement mechanism 9 is as follows: When the output end of the transverse movement telescopic rod 93 extends, it pushes the transverse movement seat 91 to move laterally. The transverse movement seat 91 drives the clamp 7 to move laterally, and the clamp 7 holds the steel billet 20 and the steel ball 30 and moves laterally, so that the steel billet 20, which was originally located in the feeding track 4, moves laterally to above the forming lower die 2, the steel ball 30, which was originally located inside the forming lower die 2, moves laterally to above the trimming lower die 3, and the steel ball 30, which was originally located inside the trimming lower die 3, moves laterally to above the discharge track 5. Conversely, when the output end of the transverse movement telescopic rod 93 retracts, it drives the transverse movement seat 91 to move laterally in the opposite direction and reset, and the transverse movement seat 91 drives the clamp 7 to reset laterally in the opposite direction.

[0054] Furthermore, when the clamping mechanism 8 drives the two clamping seats 81 to move closer or further apart in the longitudinal direction, the two clamping seats 81 drive the transverse moving seat 91 to move closer or further apart in the longitudinal direction together. The transverse moving seat 91 drives the slide rod 92 to move together in the longitudinal direction. The slide rod 92 can slide and engage with the slide hole 931 located at the output end of the transverse telescopic rod 93 in the longitudinal direction. Therefore, the transverse moving mechanism 9 will not interfere with the clamping action of the clamping mechanism 8.

[0055] The working principle of this embodiment 1 is as follows: The initial state of this device is as follows: See Figure 1 and Figure 2 The lifting column 61 in the lifting mechanism 6 rests on the worktable 1. The output end of the clamping drive component 82 in the clamping mechanism 8 is in a retracted state. The output end of the transverse telescopic rod 93 in the transverse mechanism 9 is in a retracted state. The two clamps 7 are located on both sides of the forming lower mold 2 and the trimming lower mold 3. The cylindrical groove 71 on the clamp 7 corresponds to the position of the feeding track 4. The first spherical groove 72 corresponds to the position of the forming lower mold 2. The second spherical groove 73 corresponds to the position of the trimming lower mold 3.

[0056] In the initial state, when the punch of the forging equipment carries the forming upper die and the trimming upper die downward, it will not be hindered by the two clamps 7, ensuring smooth forging and trimming.

[0057] After forging is completed, the steel balls 30 in the trimming die 3 need to be transferred to the discharge track 5, the steel balls 30 with flash 301 in the forming die 2 need to be transferred to the trimming die 3, and the cylindrical steel billet 20 in the feeding track 4 need to be transferred to the forming die 2. The transfer process is as follows: (1) The output ends of the two clamping drive members 82 in the clamping mechanism 8 extend out and push the two clamping seats 81 close to the forming lower mold 2 and the trimming lower mold 3.

[0058] During this process, the two clamping seats 81 drive the two transverse sliding seats 91 to move closer to each other, and the two transverse sliding seats 91 drive the two clamps 7 to move closer to each other; the two clamping seats 81 overcome the elastic force of the lifting elastic element 64 and push the two lifting seats 63 to move closer to each other, the two lifting seats 63 push the bottom of the lifting connecting rod 62 to move closer to the forming lower mold 2 and the trimming lower mold 3, the top of the lifting connecting rod 62 pushes the lifting column 61 upward, the lifting column 61 in the forming lower mold 2 pushes the steel ball 30 in the forming lower mold 2 upward, and the lifting column 61 in the trimming lower mold 3 pushes the steel ball 30 in the trimming lower mold 3 upward.

[0059] After the steel balls 30 in the forming lower die 2 and the trimming lower die 3 are ejected, the cylindrical grooves 71 on the two clamps 7 clamp the cylindrical steel billet 20 in the feeding track 4, the first spherical grooves 72 on the two clamps 7 clamp the steel balls 30 ejected by the lifting column 61 in the forming lower die 2, and the second spherical grooves 73 on the two clamps 7 clamp the steel balls 30 ejected by the lifting column 61 in the trimming lower die 3. The clamping drive 82 is turned off in order to maintain the state of clamping the steel billet 20 and the steel balls 30.

[0060] (2) The output end of the transverse telescopic rod 93 in the transverse mechanism 9 extends out, pushing the slide rod 92 to move laterally. The slide rod 92 drives the transverse seat 91 to move laterally, and the transverse seat 91 drives the clamp 7 to move laterally. The clamp 7 clamps the steel billet 20 and the steel ball 30 to move laterally, so that the steel billet 20, which was originally located in the feeding track 4, moves laterally to the top of the forming lower mold 2, the steel ball 30, which was originally located inside the forming lower mold 2, moves laterally to the top of the trimming lower mold 3, and the steel ball 30, which was originally located inside the trimming lower mold 3, moves laterally to the top of the discharge track 5. After moving to the position, the transverse telescopic rod 93 is stopped.

[0061] (3) The output ends of the two clamping drive members 82 in the clamping mechanism 8 retract, causing the two clamping seats 81 to leave the forming lower mold 2 and the trimming lower mold 3.

[0062] During this process, the two clamping seats 81 drive the two transverse moving seats 91 to move away from each other, and the two transverse moving seats 91 drive the two clamps 7 to move away from each other, so that the steel billet 20 in the cylindrical groove 71 falls into the forming lower mold 2, the steel ball 30 with flash 301 falls into the trimming lower mold 3, the steel ball 30 with flash 301 removed falls into the discharge track 5, and the steel ball 30 falling into the discharge track 5 rolls down along the discharge track 5 onto the discharge conveyor, and is transported by the discharge conveyor to the next process.

[0063] At the same time, the lifting seat 63 is pushed away from the forming lower mold 2 and the trimming lower mold 3 by the elastic force of the lifting elastic element 64. The lifting seat 63 drives the bottom of the lifting connecting rod 62 to leave the forming lower mold 2 and the trimming lower mold 3. The top of the lifting connecting rod 62 pulls the lifting column 61 down and back onto the worktable 1. Furthermore, under the gravity of the steel billet 20 and the steel ball 30, the lifting column 61 is also driven down and back onto the worktable 1, so that the steel billet 20 completely enters the forming lower mold 2 and the steel ball 30 with flash 301 completely enters the trimming lower mold 3.

[0064] (4) The output end of the transverse telescopic rod 93 in the transverse mechanism 9 retracts, causing the slide rod 92 to move in the opposite direction. The slide rod 92 causes the transverse seat 91 to move in the opposite direction, and the transverse seat 91 causes the clamp 7 to move in the opposite direction, restoring the initial state of the device.

[0065] Based on the working principle described above in Embodiment 1, it can be seen that Embodiment 1 has the following effects: First, the lifting mechanism 6 can eject the steel balls 30 from the forming lower die 2 and the trimming lower die 3; the clamping mechanism 8 can drive the two clamps 7 to move closer to each other and clamp the steel billet 20 in the feeding track 4, the steel balls 30 ejected by the lifting mechanism 6 in the forming lower die 2 and the trimming lower die 3; the lateral movement mechanism 9 can drive the clamps 7 to move laterally while holding the steel billet 20 and the steel balls 30; when the clamping mechanism 8 drives the two clamps 7 to separate from each other, the steel billet 20 and the steel balls 30 can be released to their current positions.

[0066] Thus, this device can complete the following operations: the feeding operation of the steel billet 20 from the feeding track 4 to the forming lower die 2; the transfer operation of the steel ball 30 with flash 301 from the forming lower die 2 to the trimming lower die 3; and the discharge operation of the steel ball 30 with flash 301 removed from the trimming lower die 3 to the discharge track 5. In other words, this device realizes the transfer processes from the feeding station to the forming station, from the forming station to the trimming station, and from the trimming station to the discharge station.

[0067] In summary, this device enables mechanized feeding, transfer, and discharging operations, eliminating the need for manual labor and saving time and effort while improving safety.

[0068] Secondly, because the lifting mechanism 6 ejects the steel ball 30 from the forming lower mold 2 and the trimming lower mold 3, and the clamping mechanism 8 clamps the ejected steel ball 30, the clamping mechanism 8 can clamp the steel ball 30 at its thickest part in the vertical direction, which can improve the clamping reliability, reduce the risk of the steel ball 30 falling off, and improve the reliability of the device in the transfer operation.

[0069] Third, when the lifting column 61 in the lifting mechanism 6 does not lift the steel ball 30, the lifting column 61 rests on the top surface of the workbench 1, so that the lifting column 61 can withstand the impact force during forging and ensure the reliability of the forging operation.

[0070] Fourth, the lifting mechanism 6 can be linked with the clamping mechanism 8. When the two clamping seats 81 in the clamping mechanism 8 approach each other, the lifting seat 63 in the lifting mechanism 6 can be pushed closer to the forming lower mold 2 and the trimming lower mold 3, so that the lifting column 61 in the lifting mechanism 6 pushes out the steel balls 30 in the forming lower mold 2 and the trimming lower mold 3. Conversely, when the two clamping seats 81 move away from each other, the lifting seat 63 in the lifting mechanism 6 can be allowed to leave the forming lower mold 2 and the trimming lower mold 3, so that the lifting column 61 falls back to its original position. There is no need to set up a separate power source to drive the lifting column 61 to rise and fall, which helps to save energy and reduce costs. In addition, the lifting mechanism 6 and the clamping mechanism 8 operate synchronously, which can improve the adjustment efficiency.

[0071] Example 2: This embodiment 2 is an improvement upon embodiment 1: See Figures 12 to 18A station transfer device for steel ball forging also includes a blocking mechanism 10. The blocking mechanism 10 includes a baffle 101, a blocking elastic element 102, a blocking connecting rod 103, and a blocking seat 104.

[0072] See Figure 13 and Figure 16 The end of the feeding track 4 and the beginning of the discharge track 5 are both provided with movable grooves 1011. A baffle 101 is provided in the movable groove 1011, and the baffle 101 slides vertically with the movable groove 1011.

[0073] See Figure 14 and Figure 17 The end of the feeding track 4 and the beginning of the discharge track 5 are both connected to the bottom of the baffle 101 through the blocking elastic element 102. The blocking elastic element 102 is a spring and is used to pull the baffle 101 upward.

[0074] See Figure 13 and Figure 16 The bottom of the baffle 101 is rotatably connected to the bottom of the blocking link 103, and the top of the blocking link 103 is rotatably connected to the top of the blocking seat 104.

[0075] See Figure 12 The shielding seat 104 is fixedly installed on the lifting seat 63.

[0076] The principle of transferring the steel billet 20 and the steel ball 30 in this embodiment 2 is as follows: (1) The output ends of the two clamping drive members 82 in the clamping mechanism 8 extend out and push the two clamping seats 81 close to the forming lower mold 2 and the trimming lower mold 3.

[0077] In this process, firstly, the two clamping seats 81 drive the two transverse sliding seats 91 to move closer to each other, and the two transverse sliding seats 91 drive the two clamps 7 to move closer to each other; the two clamping seats 81 overcome the elastic force of the lifting elastic element 64 and push the two lifting seats 63 to move closer to each other, and the two lifting seats 63 push the bottom of the lifting connecting rod 62 to move closer to the forming lower mold 2 and the trimming lower mold 3, and the top of the lifting connecting rod 62 pushes the lifting column 61 upward, the lifting column 61 in the forming lower mold 2 pushes the steel ball 30 in the forming lower mold 2 upward, and the lifting column 61 in the trimming lower mold 3 pushes the steel ball 30 in the trimming lower mold 3 upward.

[0078] Secondly, the two lifting seats 63 drive the two blocking seats 104 to move closer to each other. The blocking seats 104 drive the top of the blocking connecting rod 103 to move closer to the forming lower mold 2 and the trimming lower mold 3. The bottom of the blocking connecting rod 103 pushes the baffle 101 to overcome the elastic force of the blocking elastic element 102 and move down in the movable groove 1011, so that the baffle 101 in the feeding track 4 no longer blocks the feeding track 4, and the baffle 101 on the discharge track 5 no longer blocks the discharge track 5, so that the baffle 101 will not hinder the subsequent lateral translation of the steel billet 20 and the steel ball 30.

[0079] When the steel balls 30 in the forming lower die 2 and the trimming lower die 3 are ejected, and the baffles 101 on the feeding track 4 and the discharge track 5 move down, the cylindrical grooves 71 on the two clamps 7 clamp the cylindrical steel billet 20 in the feeding track 4, the first spherical grooves 72 on the two clamps 7 clamp the steel balls 30 ejected by the lifting column 61 in the forming lower die 2, and the second spherical grooves 73 on the two clamps 7 clamp the steel balls 30 ejected by the lifting column 61 in the trimming lower die 3. The clamping drive 82 is shut off in order to maintain the state of clamping the steel billet 20 and the steel balls 30.

[0080] (2) The output end of the transverse telescopic rod 93 in the transverse mechanism 9 extends out, pushing the slide rod 92 to move laterally. The slide rod 92 drives the transverse seat 91 to move laterally, and the transverse seat 91 drives the clamp 7 to move laterally. The clamp 7 clamps the steel billet 20 and the steel ball 30 to move laterally, so that the steel billet 20, which was originally located in the feeding track 4, moves laterally to the top of the forming lower mold 2, the steel ball 30, which was originally located inside the forming lower mold 2, moves laterally to the top of the trimming lower mold 3, and the steel ball 30, which was originally located inside the trimming lower mold 3, moves laterally to the top of the discharge track 5. After moving to the position, the transverse telescopic rod 93 is stopped.

[0081] (3) The output ends of the two clamping drive members 82 in the clamping mechanism 8 retract, causing the two clamping seats 81 to leave the forming lower mold 2 and the trimming lower mold 3.

[0082] During this process, the two clamping seats 81 drive the two transverse moving seats 91 to move away from each other, and the two transverse moving seats 91 drive the two clamps 7 to move away from each other, so that the steel billet 20 in the cylindrical groove 71 falls into the forming lower mold 2, the steel ball 30 with flash 301 falls into the trimming lower mold 3, the steel ball 30 with flash 301 removed falls into the discharge track 5, and the steel ball 30 falling into the discharge track 5 rolls down along the discharge track 5 onto the discharge conveyor, and is transported by the discharge conveyor to the next process.

[0083] At the same time, firstly, the lifting seat 63 is pushed away from the forming lower mold 2 and the trimming lower mold 3 by the elastic force of the lifting elastic element 64. The lifting seat 63 drives the bottom of the lifting connecting rod 62 to leave the forming lower mold 2 and the trimming lower mold 3. The top of the lifting connecting rod 62 pulls the lifting column 61 down and back onto the worktable 1. Furthermore, under the gravity of the steel billet 20 and the steel ball 30, the lifting column 61 is also driven down and back onto the worktable 1, so that the steel billet 20 completely enters the forming lower mold 2 and the steel ball 30 with flash 301 completely enters the trimming lower mold 3.

[0084] Secondly, the lifting seat 63 drives the blocking seat 104 away from the forming lower mold 2 and the trimming lower mold 3. The blocking seat 104 drives the top of the blocking connecting rod 103 away from the forming lower mold 2 and the trimming lower mold 3. The baffle 101 moves upward in the movable groove 1011 under the elastic force of the blocking elastic element 102. The baffle 101 drives the bottom of the blocking connecting rod 103 to move upward, so that the feeding track 4 and the discharge track 5 are blocked by the baffle 101 again, so that the steel billet 20 in the feeding track 4 will not accidentally enter the forming lower mold 2, and the steel ball 30 in the discharge track 5 will not accidentally enter the trimming lower mold 3, thereby improving the reliability of the entire device.

[0085] (4) The output end of the transverse telescopic rod 93 in the transverse mechanism 9 retracts, causing the slide rod 92 to move in the opposite direction. The slide rod 92 causes the transverse seat 91 to move in the opposite direction, and the transverse seat 91 causes the clamp 7 to move in the opposite direction, restoring the initial state of the device.

[0086] Based on the working principle described above in Embodiment 2, it can be seen that Embodiment 2 has the following advantages: First, by setting up the shielding mechanism 10, when there is no need to transfer the billet 20 and the steel ball 30, the baffle 101 can shield the end section of the feeding track 4 and the beginning end of the discharge track 5, so that the billet 20 in the feeding track 4 will not accidentally enter the forming lower mold 2, and the steel ball 30 in the discharge track 5 will not accidentally enter the trimming lower mold 3, which is conducive to improving the reliability of the entire device.

[0087] Secondly, the blocking mechanism 10 can be linked with the lifting mechanism 6. When the lifting column 61 in the lifting mechanism 6 lifts the steel ball 30 in the forming lower die 2 and the trimming lower die 3, the baffle 101 in the blocking mechanism 10 moves down to open the feeding track 4 and the discharge track 5, ensuring that the billet 20 and the steel ball 30 can be smoothly transferred to their positions. Conversely, when the lifting column 61 in the lifting mechanism 6 falls back down, the baffle 101 in the blocking mechanism 10 moves up to block the feeding track 4 and the discharge track 5 again, ensuring that during the forging process, the billet 20 in the feeding track 4 will not accidentally enter the forming lower die 2, and the steel ball 30 in the discharge track 5 will not accidentally enter the trimming lower die 3. No additional power source is needed to drive the baffle 101 to move up and down, which is beneficial for energy saving and cost reduction. Furthermore, the blocking mechanism 10 and the lifting mechanism 6 can move synchronously through linkage, which can improve adjustment efficiency.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
