[0030] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0031] For reference Figures 1-10As shown, a roll forging machine for aluminum product processing includes a base 1 and a roll forging mechanism 2 mounted on the base 1. The roll forging mechanism 2 consists of a pair of rolls driven by a motor and rotating synchronously in opposite directions via a reducer and gear seat. Each roll is fixedly equipped with a roll forging die with specific grooves. The grooves are distributed according to the process sequence. When the heated aluminum billet enters the gap between the two rolls under the push of the feeding mechanism, the rotating die periodically and locally crushes the metal, causing it to undergo plastic deformation segment by segment. Specifically, the billet cross-section matches the groove, the surface area increases, and the length extends, thereby accurately forming a preset stepped shaft or variable cross-section forging, and simultaneously optimizing its... The internal metal fiber flow direction, a linear guide rail is provided at one end of the base 1, and a mounting frame 8 is movably mounted on the linear guide rail. The mounting frame 8 is provided with a driving mechanism for driving the workpiece displacement. In a preferred embodiment, the driving mechanism includes a linear guide rail provided on the top of the mounting frame 8, a reciprocating frame 12 movably connected to the linear guide rail, a linear guide rail provided on one side of the reciprocating frame 12, a slide 13 movably mounted on the linear guide rail, a clamping body 11 is mounted on one end of the slide 13, the clamping body 11 is used to clamp the workpiece, and a first cylinder 10 for driving the reciprocating frame 12 displacement is provided at the end of the mounting frame 8 away from the clamping body 11. The top of the mounting frame 8 is provided with multiple parallel straight grooves 20, which correspond one-to-one with the grooves on the roll. The ends of adjacent straight grooves 20 away from the roll forging mechanism 2 are connected by inclined grooves 21. The inner walls of the straight grooves 20 and the inclined grooves 21 are smoothly transitioned. Limiting blocks 22 are provided at the ends of the straight grooves 20 and the inclined grooves 21, respectively. One end of the limiting block 22 is inclined, and the other end is vertical. The bottom of the slide block 13 is provided with a blind hole 24. A guide shaft 25 is vertically and movably arranged inside the blind hole 24 and is movably connected to the straight grooves 20 and the inclined grooves 21. An elastic element 26 is provided at the top of the guide shaft 25. The elastic element 26 is preferably a spring. The upper and lower ends are fixed to the top wall of the blind hole 24 and the top wall of the guide shaft 25, respectively. When the guide shaft 25 passes the limiting block 22, it can rise and compress the elastic element 26. After separating from the limiting block 22, it can fall automatically. When the guide shaft 25 reaches the end of the straight groove 20 away from the roll forging mechanism 2, it will pass the limiting block 22 in the straight groove 20. When the guide shaft 25 moves towards the roll forging mechanism 2 again, it will enter the inclined groove 21 under the restriction of the limiting block 22. When the guide shaft 25 enters another straight groove 20 from the inclined groove 21, the guide shaft 25 will pass the limiting block 22 in the inclined groove 21. This process is repeated. In order to reduce friction, a ball bearing is movably provided on the inner side of the bottom of the guide shaft 25.

[0032] To facilitate the reset of the fixture body 11, the present invention also includes a reset mechanism for resetting the slide block 13 to its initial position. In one embodiment, the reset mechanism includes a reset through groove 23 disposed on one end of a plurality of straight grooves 20 near the end of the roll forging mechanism 2. A guide slope 15 is provided at the bottom of one end of the straight groove 20 near the reset through groove 23. The guide slope 15 guides the guide shaft 25 into one of the straight grooves 20 at the edge. A fixing frame 14 is provided at the bottom of the mounting bracket 8, and a mounting bracket 14 is provided at its upper end to align with the guide shaft 25. The corresponding reset ramp 16 has a ramp on one side. When the guide shaft 25 is in the reset slot 23, the elastic element 26 is in the reset state. At this time, the lower end of the guide shaft 25 protrudes from the bottom of the mounting frame 8 and corresponds to the reset ramp 16. One end of the base 1 is provided with a hydraulic cylinder 7 for driving the mounting frame 8 to move. When the mounting frame 8 moves away from the roll forging mechanism 2, the guide shaft 25 can be guided by the ramp on one side of the reset ramp 16 to move along the reset slot 23, thereby resetting the fixture body 11 to the initial position.

[0033] The base 1, at the end furthest from the mounting frame 8, is provided with a feeding trough 3 for receiving processed workpieces. The base 1, at the end closest to the feeding trough 3, is provided with a linkage assembly for driving the feeding trough 3 to move and rotate. In one embodiment, the linkage assembly includes a mounting cavity 6 located on the side wall of the end of the base 1 furthest from the mounting frame 8. A first traction frame 9 extending to the side of the mounting cavity 6 is provided on one side of the mounting frame 8. Racks 33 are provided on one side of the first traction frame 9 and one side of the inner cavity of the mounting cavity 6. The racks 33 located within the inner cavity of the mounting cavity 6 are movably connected to the inner wall of the mounting cavity 6. A gear 34 is rotatably arranged between the two racks 33 on the inner side of the mounting cavity 6. A linear guide rail is provided in the mounting cavity 6, and the racks 33 located within the mounting cavity 6 are movably connected to this linear guide rail. A second traction frame 35 extending to the top of the base 1 is installed on the rack 33 in the mounting cavity 6. A horizontal shaft 36 corresponding to the unloading groove 3 is provided on the top of the base 1. A sleeve 37 that is movably sleeved with the horizontal shaft 36 is provided at the bottom of the unloading groove 3. The upper end of the second traction frame 35 is rotatably connected to one end of the sleeve 37 through a bearing. A spiral first guide groove 19 is provided on the outer wall of one end of the horizontal shaft 36, and a third guide groove 38 corresponding to the first guide groove 19 is provided on the other end. A second guide block 39 is provided on the inner side of the sleeve 37 for movably guiding and cooperating with the first guide groove 19 and the third guide groove 38. Thus, the unloading groove 3 can be flipped outward after being displaced a certain distance away from the roll forging mechanism 2. One side of the inner cavity of the unloading groove 3 is an inclined surface, so that the workpiece rolls down easily when the unloading groove 3 is flipped.

[0034] Furthermore, the aforementioned clamp body 11 is a pneumatic clamp, which includes a clamping hole 27 located at one end of the clamp body 11 near the roll forging mechanism 2. The clamping hole 27 is used for insertion of one end of the workpiece. A clamping block 29 for clamping the outer wall of the workpiece is movably arranged radially along the inner periphery of the clamp body 11 near the clamping hole 27. An inclined second guide groove 30 is provided on the clamping block 29. A sliding frame 31 is movably arranged axially along the inner side of the clamp body 11 near the clamping hole 27. One end of the sliding frame 31... A sliding frame 31 is provided and is movably guided by the second guide groove 30. A fourth cylinder 28 is installed on the inner side of the end of the fixture body 11 away from the clamping hole 27. The output shaft end of the fourth cylinder 28 has a T-shaped structure and passes through the sliding frame 31 and is movably connected to the sliding frame 31. Thus, when the fourth cylinder 28 retracts, it can pull the sliding frame 31 through the T-shaped structure. At this time, the clamping block 29 can move inward toward the clamping hole 27. When the fourth cylinder 28 extends outward, it can move relative to the sliding frame 31, thereby pushing the workpiece out of the clamping hole 27.

[0035] In order to protect the area of ​​the mounting frame 8, a cover 5 is installed on the end of the base 1 near the mounting frame 8 to cover the mounting frame 8. The cover 5 is provided with a transparent observation window and is detachable for easy maintenance and inspection.

[0036] Working principle: During use, the guide shaft 25 is located at the end of a straight groove 20 on the edge, the elastic element 26 is in the reset state, and the lower end of the guide shaft 25 corresponds to the guide slope 15. The gap between the first cylinder 10 and the two rolls on the forging mechanism 2 corresponds. The workpiece to be processed is placed inside one end of the loading groove 4 by a robot or manually. Then, the third cylinder 18 drives the loading groove 4 to move. After that, one end of the second cylinder 17 pushes the workpiece to move, so that one end of the workpiece is inserted into the clamping hole 27 at one end of the fixture body 11. The reset through groove 23 is retracted. The T-shaped structure at the output end of the fourth cylinder 28 pulls the sliding frame 31. The sliding frame 31 drives the first guide block 32 to move synchronously. Under the action of the second guide groove 30, the clamping block 29 moves radially. One end of the clamping block 29 is aligned with the workpiece. The workpiece is clamped at the end of the outer wall, at which point it corresponds to the first groove on the roll. Then, the roll forging mechanism 2 and the first cylinder 10 are controlled to operate. While the roll extrudes the workpiece, the first cylinder 10 drives the workpiece to move outward through the reciprocating frame 12. The bottom of the guide shaft 25 enters the straight groove 20 at the edge through the guide slope 15. When the bottom of the guide shaft 25 passes the limiting block 22 in the straight groove 20, it will automatically rise and compress the elastic element 26, and then move down to reset. When the first cylinder 10 drives the reciprocating frame 12 to move towards the roll forging mechanism 2, due to the restriction on one side of the limiting block 22 in the straight groove 20, the guide shaft 25 will enter another straight groove 20 through the inclined groove 21. Then, the guide shaft 25 drives the fixture body 11 and the workpiece to move synchronously through the slide block 13. At this time, the workpiece corresponds to the second groove. The workpiece is pressed again by the rollers, while the first cylinder 10 moves the workpiece outward again. This process is repeated until the guide shaft 25 reaches the straight groove 20 on the other edge, completing the last groove processing of the workpiece. The rollers on the forging mechanism 2 stop rotating, and the guide shaft 25 enters one end of the reset groove 23 under the push of the first cylinder 10. At this time, the elastic element 26 is fully reset, causing the guide shaft 25 to move downward. The lower end of the guide shaft 25 protrudes from the bottom of the mounting bracket 8, and at this time, the lower end of the guide shaft 25 matches the inclined surface of the reset inclined plate 16. The fourth cylinder 28 extends outward, thereby pushing the workpiece out. The workpiece falls into the unloading groove 3 for collection. Then, the hydraulic cylinder 7 is controlled to move the mounting bracket 8 outward as a whole, and the lower end of the guide shaft 25 is gradually pushed by the inclined surface of the reset inclined plate 16 until the guide shaft 25 reaches the reset groove 23. At the other end of the through slot 23, the workpiece returns to its initial position. Simultaneously with the outward movement of the mounting frame 8, the first traction frame 9 also moves synchronously. The first traction frame 9 drives a rack 33 to move, and under the action of the gear 34, another rack 33 drives the second traction frame 35 to move. The second traction frame 35, through the sleeve 37, drives the unloading trough 3 to move. The second guide block 39 enters the first guide slot 19 from the third guide slot 38. Then, under the action of the first guide slot 19, the unloading trough 3 flips outward. With the action of the inclined surface on one side of the unloading trough 3's inner cavity, the workpiece can fall and be caught by a special receiving device. Subsequently, the hydraulic cylinder 7 drives the mounting frame 8 to reset, and the fixture body 11 returns to the gap between the two rollers. Then, the third cylinder 18 and the second cylinder 17 work together to feed the workpiece again.Furthermore, the workpieces in the feeding trough 4 are placed in advance when the previous workpiece is about to finish processing, so that when processing resumes, the processed and collected workpieces can be moved separately to the next process.

[0037] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
