Description

Technical Field

[0001] This invention relates to a feeding device, and more particularly to an automatic feeding device for hot forging, belonging to the technical field of metal processing equipment. Background Technology

[0002] After hot forging is formed and demolded, the blank will have flash generated during the forming process on its outer periphery. The forging and flash need to be separated by punching through a punch press. In this process, the punch press slide drives the punch to act on the hot forging on the stripping die. The forging and flash are separated by punching force. After separation, the flash is usually left on the working end face of the stripping die, while the forging falls to the receiving area at the bottom of the punch press under the action of punching force and its own gravity.

[0003] Currently, the industry generally uses manual operation to unload the separated flash and forgings. Operators need to hold a clamp and reach close to the punching machine's working area to pick up and remove the flash one by one from the end face of the stripping die. At the same time, they need to bend down to the bottom of the die to clamp the fallen forgings and transfer them to the conveyor belt of the production line for subsequent processing. This manual unloading method not only has significant safety hazards, but also low efficiency. In addition, the positioning accuracy of manual clamping and transfer is poor, which can easily cause the surface of the forgings to be bumped and deformed, affecting the product forming quality.

[0004] To address these issues, an automatic hot forging feeding device was designed. Summary of the Invention

[0005] The main objective of this invention is to provide an automatic hot forging ejector device. A vertical rack is securely connected to the bottom of the punch press slide via a fixing plate, and fixed to the worktable via mounting holes in a U-shaped plate. The upper gear, rotatably mounted on the top of the worktable, meshes with the vertical rack and upper rack, mechanically linking the punching action and flash removal action. When the punch moves downwards to separate the forging from the flash, the upper rack moves synchronously towards the top of the blank, pre-limiting the flash and effectively preventing the high-temperature flash from sticking to the punch after separation, ensuring smooth punching operation. When the upper rack reaches its limit position, the rotating mechanism automatically drives the end pusher to unfold. After the punch completes the separation and resets, the unfolded pusher accurately pushes the flash into the scrap groove along the end face of the stripping die. After completion, the push block automatically resets to the hidden groove via a rotating mechanism, without affecting the next stamping operation. The entire flash removal process requires no additional power source and is fully integrated with the stamping process, replacing the high-risk operation of manually grasping flash at close range. This significantly reduces safety hazards such as heat radiation burns and equipment malfunctions. By integrating a forging pushing mechanism consisting of a lower ear plate, lower shaft, lower gear, limit block, lower rack, and push plate at the bottom of the C-shaped plate, the synchronous meshing transmission of the vertical rack and lower gear allows flash removal and forging pushing operations to be carried out simultaneously. As the punch resets and the flash is pushed out, the lower rack drives the push plate to slide along the receiving platform, smoothly pushing the fallen forging to the production line conveyor belt. This achieves integrated operation of flash removal and forging conveying, eliminating the need for manual handling of the two materials separately and significantly improving the efficiency of continuous production line operation.

[0006] The objective of this invention can be achieved by adopting the following technical solution:

[0014] Preferably, wear-resistant bushings are provided on the inner wall of the vertical guide groove of the limiting block one and the inner wall of the horizontal guide groove of the limiting block two.

[0015] Preferably, the rotating mechanism includes a strip groove, a slide rod, a first fixed block, a second fixed block, a connecting rod, and a lever. The strip groove is opened at the top along the length direction of the upper rack. The slide rod is slidably arranged inside the strip groove along the length direction. The first fixed block is vertically fixed at the top of the slide rod away from the slider. The second fixed block is fixed at the middle position of the top of the slide rod. The first fixed block and the second fixed block are located on both sides of the second limiting block, and the second fixed block is initially attached to the side of the second limiting block. A lever is fixedly installed at the hinge end of the push block. A connecting rod is hinged between the end of the slide rod and the end of the lever.

[0016] Preferably, the end face of the upper rack is provided with a hidden groove that matches the shape of the push block. After the push block is reset, it is completely embedded in the hidden groove, and the outer surface of the push block is flush with the end face of the upper rack.

[0017] Preferably, a limiting groove is provided at one end of the strip groove near the push block. The length of the limiting groove is less than the length of the lever. The limiting groove is used to limit the extreme rotation angle of the push block.

[0018] Preferably, a waste trough is fixedly provided at the bottom of the C-shaped plate. The waste trough is inclined, with the opening of the waste trough facing the pushing direction of the push block, and the width of the opening of the waste trough is greater than the maximum distance between the two sets of upper racks.

[0019] Preferably, the forging pusher mechanism includes a lower ear plate, a lower shaft, a lower gear, a lower rack, and a pusher plate.

[0022] The beneficial effects of this invention are as follows:

[0023] This invention provides an automatic hot forging feeding device. A vertical rack is securely connected to the bottom of the punch press slide via a fixing plate, and fixed to the worktable via mounting holes in a U-shaped plate. The upper gear, rotatably mounted on the top of the worktable, meshes with the vertical rack and upper rack, mechanically linking the punching action and flash removal action. When the punch moves downward to separate the forging from the flash, the upper rack moves synchronously towards the top of the blank, pre-limiting and constraining the flash, effectively preventing the high-temperature flash from sticking to the punch after separation, thus preserving the workpiece. The stamping process proceeds smoothly. When the upper rack moves to its limit position, the rotating mechanism can automatically drive the end push block to unfold. When the punch completes the separation operation and resets, the unfolded push block can accurately push the flash into the scrap groove along the end face of the stripping die. After the push is completed, the push block is automatically reset to the hidden groove by the rotating mechanism, which does not affect the next stamping operation. The entire flash handling process does not require an additional power source and is fully linked with the stamping process. It replaces the high-risk operation of manually picking up flash at close range, greatly reducing safety hazards such as heat radiation burns and equipment malfunctions.

[0024] By integrating a forging pushing mechanism consisting of a lower ear plate, a lower shaft, a lower gear, a limit block, a lower rack, and a push plate at the bottom of the C-shaped plate, the synchronous meshing transmission between the vertical rack and the lower gear enables the flash removal and forging pushing operations to be carried out simultaneously. As the punch resets and the flash is pushed out, the lower rack drives the push plate to slide along the receiving platform, smoothly pushing the fallen forging to the production line conveyor belt. This achieves integrated operation of flash removal and forging conveying, eliminating the need for manual handling of the two materials separately and significantly improving the efficiency of continuous production line operation.

[0042] To enable those skilled in the art to more clearly understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0043] Example 1

[0044] like Figures 1-9 As shown, this embodiment provides an automatic hot forging pusher device, including a punch press 1, a slider 101 vertically slidably mounted on the punch press 1, a punch 102 fixed to the bottom of the slider 101, a worktable 103 located at the top of the punch press 1, a stripping die 104 fixed to the top of the worktable 103, and a receiving platform 105 located below the stripping die 104.

[0045] A U-shaped plate 2 is fixedly installed on one side of the top of the workbench 103. Upper ear plates 3 are symmetrically arranged at both ends of the top of the U-shaped plate 2. An upper shaft 4 is rotatably installed between the two sets of upper ear plates 3. Upper gears 5 are symmetrically fixedly installed at both ends of the upper shaft 4.

[0046] Both ends of the inner side of the upper ear plate 3 are vertically fixed with limit blocks 8. Each limit block 8 has a vertical guide groove. A vertical rack 7 that meshes with the upper gear 5 is vertically slidably arranged in the guide groove. A fixing plate 6 is fixedly connected between the top ends of the two sets of vertical racks 7. The fixing plate 6 is fixedly connected to the bottom of the slider 101.

[0047] Both ends of the top of the shaped plate 2 are fixed with limit blocks 2 9. The interior of each limit block 2 9 is provided with a horizontal guide groove. An upper rack 10 is horizontally slidably arranged in the horizontal guide groove. The upper rack 10 meshes with the upper gear 5. The distance between two adjacent sets of upper racks 10 is greater than the outer diameter of the punch 102 and less than the width of the hot forging billet.

[0048] A push block 11 is rotatably mounted on one end of the upper rack 10 near the slider 101. A rotating mechanism 12 is provided on the top of the upper rack 10. The rotating mechanism 12 can drive the push block 11 to rotate vertically around the rotating connection to unfold or reset.

[0049] The bottom of the U-shaped plate 2 is provided with a forging pusher mechanism 14, which is connected to the vertical rack 7 for driving and is used to push the forgings on the receiving platform 105 horizontally.

[0050] After the hot forging is demolded, it is placed on the stripping die 104. After the punch press 1 is started, the slide block 101 is driven to move vertically downward. The slide block 101 drives the punch 102 to move downward synchronously. At the same time, the fixed plate 6 drives the two sets of vertical racks 7 to slide downward along the vertical guide groove of the limiting block 8. Since the vertical rack 7 meshes with the upper gear 5, the downward movement of the vertical rack 7 will drive the upper gear 5 to rotate around the upper shaft 4, which in turn drives the upper rack 10 meshing with the upper gear 5 to move along the horizontal guide groove of the limiting block 9 towards the stripping die 104 until the ends of the upper rack 10 are located on both sides of the top of the hot forging billet, thus limiting the billet and preventing the flash from sticking to the punch 102 during subsequent separation. At the same time, the vertical rack 7 is also linked with the forging pusher mechanism 14 to push out the forging after separation.

[0051] When the punch 102 moves down to contact the hot forging billet and applies a cutting force, the forging is separated from the flash. The separated flash remains on the end face of the stripping die 104, while the forging falls onto the receiving platform 105 under the action of the cutting force and its own gravity. At this time, the slider 101 drives the punch 102 to reach the lower limit position, and the upper rack 10 also moves to the limit position close to the stripping die 104. The rotating mechanism 12 triggers and drives the push block 11 to rotate vertically around the rotating connection and unfold, so that the push block 11 rotates out from the hidden groove 1208 and fits against the upper surface of the stripping die 104.

[0052] Subsequently, the punch press 1 drives the slider 101 to move vertically upward and reset. The slider 101 drives the punch 102 to move upward synchronously. The fixed plate 6 drives the vertical rack 7 to slide upward along the vertical guide groove of the first limit block 8, thereby driving the upper gear 5 to rotate in the opposite direction. The upper rack 10 moves away from the stripping die 104 along the horizontal guide groove of the second limit block 9. The unfolded push block 11 contacts the flash on the end face of the stripping die 104 during the movement and pushes the flash towards the scrap trough 13. Finally, the flash falls into the inclined scrap trough 13 for collection. At the same time, the vertical rack 7 moves upward to drive the forging pusher mechanism 14 to push the forging smoothly onto the production line conveyor belt.

[0053] When the slider 101 is fully reset, the upper rack 10 returns to its initial position, and the rotating mechanism 12 drives the push block 11 to rotate in the opposite direction to reset, so as to avoid affecting the next blank placement; the forging push mechanism 14 also returns to its initial position with the reset of the vertical rack 7, completing a complete automated operation cycle.

[0054] Example 2

[0055] The solution in Example 1 will be further described below with reference to its specific working method.

[0056] In this embodiment, the fixing plate 6 has an oblong hole 601. The fixing plate 6 is detachably fixed to the bottom of the slider 101 by bolts passing through the oblong hole 601. The two ends of the chamfered plate 2 are provided with mounting holes 201. The chamfered plate 2 is detachably fixed to the top of the workbench 103 by bolts passing through the mounting holes 201.

[0057] In this embodiment, wear-resistant bushings are provided on the inner wall of the vertical guide groove of the first limiting block 8 and the inner wall of the horizontal guide groove of the second limiting block 9.

[0058] In hot forging scenarios, component transmission is frequent and the ambient temperature is high. Wear-resistant bushings can reduce the sliding friction between the vertical rack 7 and the inner wall of the guide groove of the first limit block 8, and between the upper rack 10 and the inner wall of the guide groove of the second limit block 9, thereby reducing the wear rate of components and extending the service life of the device. At the same time, wear-resistant bushings can also ensure smoother vertical sliding of the vertical rack 7 and horizontal sliding of the upper rack 10, avoiding transmission jamming due to excessive frictional resistance, and ensuring the synchronization and stability of the linkage action.

[0059] In this embodiment, the rotating mechanism 12 includes a strip groove 1201, a slide rod 1202, a first fixing block 1203, a second fixing block 1204, a connecting rod 1205, and a lever 1206. The strip groove 1201 is opened at its top along the length direction of the upper rack 10. The slide rod 1202 is slidably arranged inside the strip groove 1201 along the length direction. The first fixing block 1203 is vertically fixed at the top end of the slide rod 1202 away from the slider 101. The second fixing block 1204 is fixed at the middle position of the top of the slide rod 1202. The first fixing block 1203 and the second fixing block 1204 are respectively located on both sides of the second limiting block 9. The second fixing block 1204 is initially attached to the side of the second limiting block 9. The lever 1206 is fixedly installed at the hinge end of the push block 11. The connecting rod 1205 is hinged between the end of the slide rod 1202 and the end of the lever 1206.

[0060] In the initial state, the side of the fixed block 1204 is in contact with the side of the limiting block 9. The end of the slide rod 1202 away from the push block 11 has a certain gap with the end of the strip groove 1201. The push block 11 is embedded in the hidden groove 1208. When the slider 101 moves down and drives the upper rack 10 to move towards the stripping mold 104, the limiting block 9 moves with the upper rack 10. The push block 11 is always hidden until the side of the fixed block 1203 is in contact with the side of the limiting block 9. As the upper rack 10 continues to move, the fixed block 1203 drives the slide rod 1202 to move towards the end away from the push block 11. When the slide rod 1202 slides, the connecting rod 1205 pulls the lever 1206, so that the lever 1206 drives the push block 11 to rotate and unfold around the hinge point until the push block 11 is in contact with the end face of the stripping mold 104.

[0061] When the slider 101 moves upward, it causes the upper rack 10 to move away from the stripping mold 104. The push block 11 pushes the flash to slide and pushes the flash into the interior of the waste trough 13. After the limit block 2 9 and the fixing block 2 1204 are in contact, as the upper rack 10 continues to move, the fixing block 2 1204 drives the slide rod 1202 to move towards the push block 11. The connecting rod 1205 pushes the lever 1206, causing the push block 11 to rotate in the opposite direction to reset and embed into the hidden groove 1208.

[0062] In this embodiment, the end face of the upper rack 10 is provided with a hidden groove 1208 that is adapted to the shape of the push block 11. After the push block 11 is reset, it is completely embedded in the hidden groove 1208, and the outer surface of the push block 11 is flush with the end face of the upper rack 10.

[0063] After the pusher block 11 is reset, it is embedded in the hidden groove 1208, which can prevent the pusher block 11 from protruding from the end face of the upper rack 10 and affecting the placement of the hot forging billet on the stripping die 104, ensuring that the billet can be stably attached to the end face of the stripping die 104 and ensuring the accuracy of punching and separation; at the same time, the hidden design can prevent the pusher block 11 from being damaged by collision when it is not in operation.

[0064] In this embodiment, a limiting groove 1207 is provided at one end of the strip groove 1201 near the push block 11. The length of the limiting groove 1207 is less than the length of the lever 1206. The limiting groove 1207 is used to limit the extreme rotation angle of the push block 11.

[0065] When the slide rod 1202 drives the lever 1206 to drive the push block 11 to rotate, the end of the lever 1206 will gradually approach the end of the limiting groove 1207. When the lever 1206 contacts the end of the limiting groove 1207, the slide rod 1202 stops sliding, and the push block 11 also stops rotating, thereby limiting the rotation angle of the push block 11 within a preset range, avoiding the push block 11 from rotating too large or too small, affecting the flash pushing effect, and ensuring that the push block 11's pushing action is stable and reliable.

[0066] In this embodiment, a waste trough 13 is fixedly provided at the bottom of the C-shaped plate 2. The waste trough 13 is inclined and the opening of the waste trough 13 faces the pushing direction of the push block 11. The width of the opening of the waste trough 13 is greater than the maximum distance between the two sets of upper racks 10.

[0067] When the pusher block 11 pushes the flash, the flash slides along the end face of the stripping mold 104 to the opening of the waste trough 13 under the pushing force of the pusher block 11. Since the waste trough 13 is inclined, the flash slides down the inner wall of the waste trough 13 to the preset collection area under its own gravity, realizing the automatic collection of the flash. The width of the trough is greater than the maximum distance between the two sets of upper racks 10, which can prevent the flash from falling to the ground and causing environmental pollution, and at the same time reduce the amount of manual cleaning of waste.

[0068] In this embodiment, the forging pusher mechanism 14 includes a lower ear plate 1401, a lower shaft 1402, a lower gear 1403, a lower rack 1405, and a pusher plate 1406. The lower ear plate 1401 is symmetrically fixed at both ends of the bottom of the U-shaped plate 2. The lower shaft 1402 is rotatably mounted between the two sets of lower ear plates 1401 through bearings. The lower gear 1403 is sleeved and keyed to both ends of the lower shaft 1402, and the lower gear 1403 meshes with the vertical rack 7. The lower rack 1405 is horizontally arranged above the receiving platform 105, and the lower rack 1405 meshes with the lower gear 1403. The pusher plate 1406 is fixed to one end of the lower rack 1405 near the receiving platform 105.

[0069] When the vertical rack 7 moves down with the slider 101, the lower gear 1403 meshing with the vertical rack 7 rotates around the lower shaft 1402, driving the lower rack 1405 meshing with the lower gear 1403 to move towards the receiving platform 105. The push plate 1406 moves forward synchronously, and before the forging falls, the push plate 1406 moves to the front of the forging's falling position. The push plate 1406 can prevent the forging from jumping forward. When the vertical rack 7 moves up with the slider 101, the lower gear 1403 rotates in the opposite direction, driving the lower rack 1405 to move away from the receiving platform 105. The push plate 1406 contacts the forging on the receiving platform 105 and applies a horizontal thrust, smoothly pushing the forging along the surface of the receiving platform 105 onto the production line conveyor belt, realizing the automatic transfer of the forging.

[0070] In this embodiment, a limiting block 3 1404 is fixed on the inner side of the lower ear plate 1401, and the interior of the limiting block 3 1404 is provided with a guide groove that matches the lower rack 1405.

[0071] The guide groove of the limiting block 3 1404 provides precise guidance for the horizontal movement of the lower rack 1405, ensuring that the lower rack 1405 drives the push plate 1406 to move along the preset trajectory, and avoiding the forging push position deviation caused by the push plate 1406 offset.

[0072] In this embodiment, the bottom of the push plate 1406 is attached to the top of the receiving platform 105, a high-temperature resistant and wear-resistant pad is bonded to the inner side wall of the push plate 1406, and a reinforcing rib is provided between the push plate 1406 and the lower rack 1405.

[0073] The bottom of the push plate 1406 fits snugly against the top of the receiving platform 105, preventing the forging from getting stuck in the gap between the push plate 1406 and the receiving platform 105, ensuring that the forging can be pushed smoothly. The high-temperature resistant and wear-resistant pad is made of ceramic matrix composite material, which can withstand the high temperature of hot forgings and reduce the friction between the push plate 1406 and the forging, avoiding scratches on the surface of the forging and ensuring product quality. The reinforcing rib is used to enhance the connection strength between the push plate 1406 and the lower rack 1405, preventing the push plate 1406 from deforming or breaking due to excessive force when pushing the forging, and extending the service life of the push plate 1406.

[0074] Example 3

[0075] The solutions in Embodiment 1 and Embodiment 2 will be further described below with reference to their specific working methods.

[0076] Initial preparation stage: First, fix the fixing plate 6 to the slider 101 with bolts, and then fix the chamfered plate 2 to the preset position of the worktable 103 through the mounting holes 201 at both ends of the chamfered plate 2. At this time, the device is in the initial state, the push block 11 is fully embedded in the hidden groove 1208 of the upper rack 10, and the outer surface is flush with the end face of the upper rack 10; in the rotating mechanism 12, the fixing block 2 1204 and the limiting block 2 9 are in contact with each other, and the end of the slide rod 1202 away from the push block 11 maintains a certain sliding distance with the end of the strip groove 1201; in the forging push mechanism 14, the push plate 1406 is a certain distance from the forging falling position. Then, the hot forging billet after demolding is placed stably on the end face of the demolding mold 104 to complete the operation preparation.

[0077] Stamping separation and linkage feeding stage: Start the punch press 1. The punch press 1 drives the slider 101 to move vertically downward, driving the punch 102 to move synchronously towards the blank. At the same time, the slider 101 drives the two sets of vertical racks 7 to slide downward along the wear-resistant bushing guide groove of the limiting block 1 8 through the fixing plate 6. The wear-resistant bushing reduces the friction between the vertical rack 7 and the guide groove, avoiding transmission jamming. Since the vertical rack 7 meshes with the upper gear 5, its downward movement drives the upper gear 5 to rotate around the upper shaft 4, thereby driving the upper rack 10 to move along the wear-resistant bushing guide groove of the limiting block 2 9 towards the stripper die 104, until the ends of the upper rack 10 are located on both sides of the top of the blank, forming a limit on the blank and preventing the flash from sticking to the punch 102 during subsequent punching.

[0078] At the same time, the vertical rack 7 meshes with the lower gear 1403, driving the lower gear 1403 to rotate around the lower shaft 1402, causing the lower rack 1405 to move along the guide groove of the limiting block three 1404 towards the receiving platform 105. The push plate 1406 advances synchronously to the front of the forging falling position, preparing to receive the forging and prevent it from jumping out. As the upper rack 10 continues to move towards the stripping mold 104, the fixing block one 1203 of the rotating mechanism 12 gradually comes into contact with the side of the limiting block two 9, and moves with the upper rack 1405. As strip 10 continues to move, fixed block 1203 drives slide rod 1202 to slide away from push block 11 along strip groove 1201. Slide rod 1202 pulls lever 1206 through connecting rod 1205, causing lever 1206 to drive push block 11 to rotate and unfold around hinge point. When the end of lever 1206 contacts the end of limiting groove 1207, slide rod 1202 stops sliding, and the rotation angle of push block 11 is limited to a preset range, which just fits against the upper surface of stripping mold 104, completing the push block unfolding action.

[0079] Forging and flash separation and receiving stage: The punch 102 continues to move down and contact the forging, applying a punching force to separate the forging from the flash; the separated flash remains on the end face of the stripping die 104, and the forging falls onto the receiving platform 105 under the action of the punching force and its own gravity. At this time, the push plate 1406 is in front of the falling position of the forging, effectively preventing the forging from jumping forward and ensuring that the forging is received smoothly.

[0080] During the synchronous pushing stage of flash and forging: After punching, the punch press 1 drives the slider 101 to move vertically upward and reset, driving the punch 102 to move upward synchronously; the fixed plate 6 drives the vertical rack 7 to slide upward along the guide groove of the first limiting block 8, driving the upper gear 5 to rotate in the opposite direction, and the upper rack 10 moves away from the stripping die 104 along the guide groove of the second limiting block 9. The unfolded push block 11 contacts the flash on the end face of the stripping die 104 during the movement, pushing the flash towards the scrap trough 13. Since the scrap trough 13 is inclined and the width of the trough is greater than the maximum distance between the two sets of upper racks 10, the flash slides down the inner wall of the scrap trough 13 to the preset collection area under the action of the pushing force and its own gravity, realizing the automatic collection of flash.

[0081] Simultaneously, the vertical rack 7 moves upward, driving the lower gear 1403 to rotate in the opposite direction, causing the lower rack 1405 to move away from the receiving platform 105 along the guide groove of the limiting block 3 1404. The push plate 1406 contacts the forging on the receiving platform 105 and applies a horizontal thrust. The bottom of the push plate 1406 fits against the top of the receiving platform 105 to prevent the forging from getting stuck in the gap. The ceramic-based high-temperature and wear-resistant pad on its inner wall reduces friction with the forging and prevents scratches on the surface of the forging. The reinforcing ribs between the push plate 1406 and the lower rack 1405 enhance the connection strength and prevent the push plate 1406 from deforming. Finally, the forging is smoothly pushed onto the production line conveyor belt, completing the automatic transfer of the forging.

[0082] Device reset and cycle preparation stage: When the slider 101 is fully reset, the upper rack 10 returns to the initial position. During this process, the second limit block 9 in the rotating mechanism 12 first engages with the second fixed block 1204. Then the upper rack 10 continues to move a distance. The second fixed block 1204 drives the slide rod 1202 to slide along the strip groove 1201 towards the push block 11. The slide rod 1202 pushes the lever 1206 through the connecting rod 1205, so that the push block 11 rotates in the opposite direction to reset and is fully embedded in the hidden groove 1208 to avoid affecting the next blank placement. At the same time, the lower rack 1405 of the forging push mechanism 14 rotates in the opposite direction with the lower gear 1403 to return to the initial position. The push plate 1406 is simultaneously reset to the front of the forging falling position. All transmission components are restored to the initial state, completing a complete automated operation cycle, and can enter the next hot forging blank processing process.
