Description

Technical Field

[0001] This invention relates to the field of metal forging technology, specifically to a positioning fixture for metal forging. Background Technology

[0002] Forging is a processing method that uses forging machinery to apply pressure to a metal billet, causing it to undergo plastic deformation to obtain forgings with specific mechanical properties, shapes, and dimensions. During metal forging, in order to forge the metal part into a specific shape and maintain its stability, the metal part needs to be placed within a positioning fixture for processing.

[0003] During metal forging, debris is generated. When the metal part is removed from the mold slot of the positioning fixture after forging is completed, some debris and impurities will remain in the mold slot. If the debris and impurities are not cleaned, it will affect the subsequent forging work. When cleaning the debris and impurities, since the mold slot has a concave structure, the debris is manually removed from the top of the mold slot. For some small debris, cleaning is not only time-consuming and laborious, but also not thorough enough, resulting in poor cleaning effect. Summary of the Invention

[0004] This invention provides a positioning fixture for metal forging. After the metal part is removed, the discharge port is opened, and the first and second cleaning rods are inserted into the mold groove. Through the circumferential rotation of the first and second cleaning rods, the debris inside the mold groove can be cleaned and discharged from the discharge port. This solves the problem mentioned in the background art that manually removing debris from the top of the mold groove is not only time-consuming and laborious, but also insufficient and has poor cleaning effect for some small debris.

[0011] As an optional embodiment of the metal forging positioning fixture of the present invention, a plurality of first limiting rollers are rotatably arranged on the first cleaning rod, a protruding plate is fixed at the end of the second cleaning rod, and a plurality of second limiting rollers are rotatably arranged on the lower surface of the protruding plate. Both the first limiting rollers and the second limiting rollers are rotatably arranged in the transmission groove.

[0012] As an optional embodiment of the metal forging positioning fixture of the present invention, a cam is fixed on the circumference of the second rotating shaft, a movable rod is elastically provided inside the first cleaning rod, a protrusion for abutting against the cam is fixed at the end of the movable rod, a striking roller slides inside the transmission groove, a striking rod is fixed at the top of the striking roller, the striking rod is elastically provided inside the first cleaning rod, and a sliding groove for the striking rod to slide is provided on the movable rod.

[0013] As an optional solution of the metal forging positioning fixture of the present invention, the end of the striking rod is fixed with a sliding protrusion, and the inner wall of the slide groove is provided with a second trajectory groove for the sliding protrusion to slide. The second trajectory groove includes a power storage part, a striking part and a reset part connected in series, and a limit plate is elastically provided at the connection between the power storage part and the reset part.

[0014] As an optional solution for the metal forging positioning fixture of the present invention, a first servo electric cylinder is fixed on the upper surface of the base, the output end of the first servo electric cylinder is fixed to the sealing block, a connecting seat is fixed on the outer surface of the positioning plate, a second servo electric cylinder is fixed on the surface of the connecting seat, and a positioning plate is fixed on the output end of the second servo electric cylinder.

[0015] As an optional solution for the metal forging positioning fixture of the present invention, a third servo electric cylinder is fixed on the surface of the support frame, the output end of the third servo electric cylinder is fixed to the mounting plate, a first servo motor is fixed on the lower surface of the mounting plate, the output end of the first servo motor is fixed to the first rotating shaft, and a connecting rod is fixed between the mounting plate and the disc.

[0016] The present invention has the following beneficial effects:

[0017] 1. This metal forging positioning fixture, after the metal part is removed from the mold slot, the sealing block moves downward to open the discharge port. The mounting plate moves downward, driving the first and second cleaning rods to move downward, so that the first and second cleaning rods contact the inner wall of the mold slot. Then, the first rotating shaft rotates, driving the first and second cleaning rods to rotate, so that the first and second cleaning rods clean the inner wall of the mold slot. During cleaning, the debris is automatically discharged through the discharge port, saving time and effort.

[0018] During cleaning, in order to improve the thoroughness of debris removal, the drive rod slides along the first track groove, allowing the second cleaning rod to extend and retract relative to the first cleaning rod. This enables the end of the second cleaning rod to move along the track of the edge of the model groove, thereby reducing cleaning dead angles and improving the debris removal effect.

[0019] 2. In this metal forging positioning fixture, when the first and second cleaning rods clean the inner wall of the mold groove, the conveyor belt rotates along the first and second cleaning rods. The rotation of the conveyor belt drives the brush to rotate, so that the cleaned debris can move from the end of the second cleaning rod to the tail of the first cleaning rod, thereby facilitating the automatic cleaning of the debris to the discharge port and making it easy for the debris to be fully discharged.

[0020] When the second cleaning bar retracts relative to the first cleaning bar, it drives the adjusting roller to move, thus tauting the conveyor belt. When the second cleaning bar extends relative to the first cleaning bar, the conveyor belt pulls the adjusting roller back to its original position. This ensures that the conveyor belt always adheres to the surfaces of both the first and second cleaning bars during the extension and retraction of the second cleaning bar, thereby increasing the stability of the conveyor belt and further improving the cleaning effect of the brush.

[0021] 3. This forged metal positioning fixture, while driving the conveyor belt to rotate, also drives the cam to rotate. Through the contact between the cam and the protrusion, the moving rod can move up and down reciprocatingly. The up and down reciprocating motion of the moving rod causes the striking rod to move up and down reciprocatingly along the slide groove. The striking rod drives the sliding protrusion to move reciprocatingly along the second track groove, causing the striking rod to drive the striking roller to move left and right reciprocatingly. This allows the striking roller to reciprocately strike the surface of the conveyor belt, causing the conveyor belt at the struck point to vibrate, thereby facilitating the removal of debris attached to the brush, making the debris cleaning more thorough, and further improving the cleaning effect.

[0035] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1, please refer to Figures 1-12A metal forging positioning fixture includes a positioning plate 2 fixed on a base 1, a model groove 3 on the positioning plate 2, a discharge port 4 in the middle of the model groove 3, a liftable sealing block 5 slidably disposed in the discharge port 4, a support frame 6 fixed on the outer surface of the base 1, a liftable mounting plate 7 disposed on the support frame 6, a first rotating shaft 8 rotatably disposed below the mounting plate 7, a first cleaning rod 9 fixed at the bottom of the first rotating shaft 8, a second cleaning rod 10 slidably disposed on the first cleaning rod 9, and the rotation of the first rotating shaft 8 drives the first cleaning rod 9 and the second cleaning rod 10 to rotate and clean the model groove 3.

[0037] A drive rod 11 is fixed on the second sweeping rod 10. A slide rail 12 is provided on the first sweeping rod 9 for the drive rod 11 to slide. A disc 13 is fixed below the mounting plate 7. A first track groove 14 is provided on the lower surface of the disc 13. The second sweeping rod 10 slides along the first track groove 14 via the drive rod 11 to extend and retract along the first sweeping rod 9.

[0038] The first track groove 14 includes a contraction portion 141 and an extension portion 142 that are connected together.

[0039] A first servo electric cylinder 39 is fixed on the upper surface of the base 1. The output end of the first servo electric cylinder 39 is fixed to the sealing block 5. A connecting seat 40 is fixed on the outer surface of the positioning plate 2. A second servo electric cylinder 41 is fixed on the surface of the connecting seat 40. A positioning plate 42 is fixed on the output end of the second servo electric cylinder 41.

[0040] A third servo cylinder 43 is fixed to the surface of the support frame 6. The output end of the third servo cylinder 43 is fixed to the mounting plate 7. A first servo motor 44 is fixed to the lower surface of the mounting plate 7. The output end of the first servo motor 44 is fixed to the first rotating shaft 8. A connecting rod 45 is fixed between the mounting plate 7 and the disc 13.

[0041] In this technical solution, the metal part is an irregularly shaped part, the specific shape of which is as follows: Figure 1 The shape of the model groove 3 shown is such that when positioning the metal part during forging, the metal part is first placed into the model groove 3. The positioning plate 42 is moved by the second servo cylinder 41 to fix the metal part. After positioning, the metal part is processed. After the metal part is forged, the second servo cylinder 41 is reset, which drives the positioning plate 42 to reset. The sealing block 5 is moved upward by the first servo cylinder 39 to lift the metal part, so that the metal part can be easily removed from the inside of the model groove 3.

[0042] After the metal parts are forged, some metal shavings remain on the inner wall of the mold groove 3. If these shavings are not cleaned, they will affect the subsequent forging of the metal parts. Therefore, after the metal parts are taken out of the mold groove 3, the first servo cylinder 39 retracts, causing the sealing block 5 to move downward and move the sealing block 5 out of the discharge port 4, opening the discharge port 4. At the same time, the third servo cylinder 43 pushes the mounting plate 7 downward, causing the first cleaning rod 9 and the second cleaning rod 10 to move downward, so that the first cleaning rod 9 and the second cleaning rod 10 contact the inner wall of the mold groove 3. Then, the first servo motor 44 drives the first rotating shaft 8 to rotate, the first rotating shaft 8 drives the first cleaning rod 9 to rotate, and the first cleaning rod 9 drives the second cleaning rod 10 to rotate, so that the first cleaning rod 9 and the second cleaning rod 10 can clean the inner wall of the mold groove 3 by rotating. During cleaning, the cleaned debris is discharged through the discharge port 4.

[0043] Because the edge of model slot 3 has an irregular structure, such as Figure 1 As shown, the edge of the model groove 3 is curved, which means that if the end of the second cleaning rod 10 moves along the circumference, there will be areas that cannot be cleaned, creating cleaning dead zones. Therefore, the second cleaning rod 10 and the first cleaning rod 9 are designed as a telescopic structure. When the first cleaning rod 9 rotates, it drives the second cleaning rod 10 to rotate, which in turn drives the drive rod 11 to rotate, causing the drive rod 11 to slide along the first track groove 14. Figure 5 As shown, the trajectory of the first track groove 14 is the same as the trajectory of the edge of the model groove 3. When the drive rod 11 slides along the contraction part 141, as... Figure 2 As shown, the drive rod 11 slides to the right along the slide rail 12, causing the second cleaning rod 10 to retract into the first cleaning rod 9. When the drive rod 11 slides along the extension 142, the drive rod 11 slides to the left along the slide rail 12, causing the second cleaning rod 10 to extend out from the first cleaning rod 9. This allows the end of the second cleaning rod 10 to move along the edge trajectory of the model groove 3, thereby reducing cleaning dead angles and increasing the thoroughness of cleaning.

[0044] In this technical solution, the top of the support frame 6 can rotate. Specifically, the top of the support frame 6 can be rotated by a motor, so that the top of the support frame 6 can be moved out of or onto the positioning plate 2. The support frame 6 is existing technology and is not an innovation of this application, so it will not be described in detail.

[0045] In Example 2, when the first cleaning rod 9 and the second cleaning rod 10 rotate and clean the inner wall of the mold groove 3, the cleaned debris cannot fully enter the discharge port 4 along the surfaces of the first cleaning rod 9 and the second cleaning rod 10, resulting in insufficient cleaning. To address this problem, this example is an improvement based on Example 1. For details, please refer to... Figures 1-12A conveyor belt 15 is slidably provided on the outer surface of the first cleaning rod 9 and the second cleaning rod 10. Several sets of bristles 16 are laid on the outer surface of the conveyor belt 15. The bristles 16 sweep the impurities to the discharge port 4 by rotating the conveyor belt 15.

[0046] An adjusting roller 17 is slidably disposed inside the first cleaning rod 9. A transmission groove 18 for the adjusting roller 17 to slide is opened in the middle of the conveyor belt 15. A first transmission rod 19 is fixed on the surface of the second cleaning rod 10. A first hydraulic oil groove 20 and a second hydraulic oil groove 21 are opened inside the first cleaning rod 9 and are connected to each other. A first piston plate 22 fixed to the first transmission rod 19 is slidably disposed in the first hydraulic oil groove 20. A second piston plate 23 is slidably disposed in the second hydraulic oil groove 21. A second transmission rod 24 is fixed on the second piston plate 23. The adjusting roller 17 is rotatably disposed at the end of the second transmission rod 24.

[0047] The first cleaning rod 9 is internally equipped with a transmission roller 25 for driving the conveyor belt 15. The top of the first cleaning rod 9 is fixed with a second servo motor 26. The output end of the second servo motor 26 is fixed with a second rotating shaft 27. The end of the second rotating shaft 27 is fixed with the transmission roller 25.

[0048] The first cleaning rod 9 is rotatably equipped with several sets of first limiting rollers 28, and the end of the second cleaning rod 10 is fixed with a protruding plate 29. Several sets of second limiting rollers 30 are rotatably equipped on the lower surface of the protruding plate 29. The first limiting rollers 28 and the second limiting rollers 30 are both rotatably arranged in the transmission groove 18.

[0049] In this technical solution, when the first cleaning rod 9 and the second cleaning rod 10 clean the inner wall of the model groove 3, such as Figure 9 and Figure 10 As shown, the second servo motor 26 drives the second rotating shaft 27 to rotate, the second rotating shaft 27 drives the transmission roller 25 to rotate, the transmission roller 25 drives the conveyor belt 15 to rotate, the movement of the conveyor belt 15 drives the brush bristles 16 to rotate, the brush bristles 16 move towards the discharge port 4, so that the brush bristles 16 can sweep the cleaned debris to the discharge port 4, thereby increasing the thoroughness of debris cleaning;

[0050] To meet the telescopic requirements of the first sweeping rod 9 and the second sweeping rod 10, when the drive rod 11 drives the second sweeping rod 10 to telescopically move, firstly, when the second sweeping rod 10 retracts into the first sweeping rod 9, as... Figure 6 and Figure 7As shown, the second cleaning rod 10 moves downward, causing the first transmission rod 19 to move downward. The downward movement of the first transmission rod 19 causes the first piston plate 22 to move downward. The downward movement of the first piston plate 22 fills the hydraulic oil inside the first hydraulic oil tank 20 into the second hydraulic oil tank 21, causing the second piston plate 23 to move upward. The second piston plate 23 drives the second transmission rod 24 to move upward. The second transmission rod 24 drives the adjusting roller 17 to move upward. The adjusting roller 17 pulls the conveyor belt 15 upward, thereby causing the second cleaning rod 10 to retract into the first cleaning rod 9 while simultaneously... The conveyor belt 15 is taut to prevent it from becoming loose. When the second cleaning rod 10 extends from inside the first cleaning rod 9, the end of the second cleaning rod 10 pushes the conveyor belt 15, causing the conveyor belt 15 to pull the adjusting roller 17, which moves downward. At the same time, the adjusting roller 17 drives the second piston plate 23 to move, pushing the hydraulic oil in the second hydraulic oil tank 21 back into the first hydraulic oil tank 20. This ensures that the conveyor belt 15 remains taut even when the second cleaning rod 10 extends from inside the first cleaning rod 9, which helps improve the cleaning effect.

[0051] In this technical solution, by setting a second limiting roller 30 at the end of the second cleaning rod 10, the top end of the conveyor belt 15 can be supported, allowing the conveyor belt 15 to be conveyed more stably at the end of the second cleaning rod 10. By setting a first limiting roller 28 on the side plate of the first cleaning rod 9, the conveyor belt 15 on the side plate of the first cleaning rod 9 can be conveyed more stably, thereby improving the stability of the movement of the conveyor belt 15; Figure 10 As shown, the first limiting rollers 28 on the left and right sides of the transmission roller 25 cooperate with the transmission roller 25 to clamp the conveyor belt 15, thereby facilitating the transmission roller 25 to drive the conveyor belt 15 to move.

[0052] In Example 3, after the brush sweeps away the debris, a small amount of debris may remain on the brush, preventing sufficient material from falling through the four discharge points and thus reducing the debris removal effect. This example addresses this issue by improving upon Example 2. For details, please refer to [link / reference]. Figures 1-12 A cam 31 is fixed on the circumference of the second rotating shaft 27. A movable rod 32 is elastically provided inside the first cleaning rod 9. A protrusion 33 for abutting against the cam 31 is fixed at the end of the movable rod 32. A knocking roller 34 slides inside the transmission groove 18. A knocking rod 35 is fixed at the top of the knocking roller 34. The knocking rod 35 is elastically provided inside the first cleaning rod 9. A sliding groove 36 is provided on the movable rod 32 for the knocking rod 35 to slide.

[0053] The end of the striking rod 35 is fixed with a sliding protrusion 37. The inner wall of the groove 36 is provided with a second track groove 38 for the sliding protrusion 37 to slide. The second track groove 38 includes a power storage part 381, a striking part 382 and a reset part 383 connected in series. A limit plate 384 is elastically provided at the connection between the power storage part 381 and the reset part 383.

[0054] In this technical solution, such as Figure 10 As shown, while the second rotating shaft 27 drives the transmission roller 25 to rotate, the second rotating shaft 27 also drives the cam 31 to rotate, causing the cam 31 to abut against the protrusion 33. A sliding plate 49 is fixed to the end of the moving rod 32. The sliding plate 49 is slidably disposed within the first cleaning rod 9. A first spring 46 is disposed between the sliding plate 49 and the inner wall of the first cleaning rod 9, providing elastic force to the moving rod 32, allowing the cam 31 and the protrusion 33 to reciprocate. This causes the protrusion 33 to drive the moving rod 32 to reciprocate up and down. The reciprocating motion of the moving rod 32 causes the striking rod 35 to reciprocate up and down along the slide groove 36. A protrusion 50 is fixed to the surface of the striking rod 35, and the protrusion 50 is slidably disposed inside the first cleaning rod 9. A second spring 47 is disposed between the protrusion 50 and the inner wall of the first cleaning rod 9. When the striking rod 35 moves downward along the slide groove 36, the striking rod 35 drives the sliding protrusion 37 to move along the second track... When the storage part 381 of the groove 38 slides, the sliding protrusion 37 drives the striking rod 35 to move to the left, the second spring 47 is compressed and stored, and the striking rod 35 moves to the left, driving the striking roller 34 to move to the left inside the transmission groove 18. When the sliding protrusion 37 slides to the striking part 382, ​​the sliding protrusion 37 loses its resistance, the second spring 47 releases its force, and the striking rod 35 is released instantly. The striking rod 35 drives the striking roller 34 to move to the right, so that the striking roller 34 strikes the conveyor belt 15, causing the conveyor belt 15 at the striking roller 34 to vibrate, thereby facilitating the removal of debris attached to the brush. The conveyor belt 15 at the striking roller 34 is located above the discharge port 4, so that the debris can fall directly into the discharge port 4 for discharge, making the debris cleaning more thorough and further improving the cleaning effect. When the moving rod 32 moves downward, the sliding protrusion 37 slides along the reset part 383 to complete the reset.

[0055] In this technical solution, such as Figure 12 As shown, a rotating groove 385 is formed on the inner wall of the first cleaning rod 9. A rotating rod 396 is rotatably mounted inside the rotating groove 385. A limiting plate 384 is fixedly sleeved on the circumference of the rotating rod 396. A torsion spring 387 is movably mounted on the circumference of the rotating rod 396. End a of the torsion spring 387 is fixed to the surface of the limiting plate 384, and end b of the torsion spring 387 is fixed to the inner wall of the rotating groove 385. An abutment block 388 is fixed to the surface of the limiting plate 384, and a stop block 389 is fixed to the inner wall of the rotating groove 385. Due to the restriction of the abutment block 388 by the stop block 389, the limiting plate 384 cannot be pressed... Figure 12 The slide protrusion 37 rotates clockwise as shown, so that when it slides downward, it can only slide downward along the power storage part 381 and will not slide downward along the reset part 383. When it slides upward along the reset part 383, the slide protrusion 37 first abuts against the limiting plate 384, causing the limiting plate 384 to press down. Figure 12 When the device rotates counterclockwise as shown, the torsion spring 387 stores force until the sliding protrusion 37 returns to its original position. At this point, the limiting plate 384 loses contact with the sliding protrusion 37, and the torsion spring 387 releases its force, causing the limiting plate 384 to return to its original position. Figure 12 This state allows the sliding protrusion 37 to complete its cyclic reciprocating motion along the second track groove 38;

[0056] In this technical solution, such as Figure 10 As shown, a positioning roller 48 is fixed inside the first cleaning rod 9. The positioning roller 48 is inserted into the transmission groove 18. Through the positioning roller 48, the distance between the positioning roller 48 and the transmission roller 25 remains unchanged. No matter how the conveyor belt 15 moves with the adjusting roller 17, the position of the conveyor belt 15 moving between the positioning roller 48 and the transmission roller 25 remains unchanged, so as not to affect the movement of the striking roller 34.

[0057] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0058] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
