Description

Technical Field

[0001] This invention relates to the field of injection mold processing technology, and more specifically, to a metal part cutting mechanism based on injection molds. Background Technology

[0002] The sprue bushing of injection molds is usually made from solid round steel bars. The main "cutting" process involves several steps. First, blanking: factories use saws or laser cutters to cut long strips of steel into short sections. Next, turning: the workpiece rotates on a lathe, and the cutting tool cuts the outer circle to the specified diameter, like peeling an apple, while simultaneously smoothing the end face. Then, drilling: because the sprue bushing is a hollow "tube," a drill bit is used to remove the material in the middle to form the main runner hole. Finally, grinding: after heat treatment and hardening, ordinary cutting tools cannot cut it. At this point, a grinding machine is used, utilizing the high-speed rotation of the grinding wheel to perform micron-level cutting on the surface to ensure its precision in fitting with the mold and injection molding machine nozzle. Finally, the sprue bushing is fully processed. The steel used to manufacture the sprue bushing is usually a solid cylindrical long bar before processing, often referred to in the industry as "round steel" or "bar stock." The first step is to cut the round steel into sections.

[0003] For smaller processing plants, a lower-cost circular saw is typically used. During processing, a cylinder clamp holds the round steel bar at the top of the workbench. A horizontal screw assembly drives the circular saw to approach the side of the clamped round steel bar and cut it. Because the process is assembly-line based, the specifications of the gate sleeves produced in the same batch are all the same, resulting in identical lengths of cut round steel bars each time. After each cut, the cylinder in the clamping mechanism slightly loosens the clamp, allowing the round steel bar to slide horizontally within the arc-shaped clamp. The longer round steel bar is then manually pushed horizontally within the clamp, pushing out the cut-off shorter round steel bar and filling the space left by the cut-off shorter bar. This completes the unloading of the cut-off short round steel bar. However, the manual pushing of the round steel bar... The distance the long steel bar is moved horizontally is entirely based on experience, making it impossible to guarantee that the pushing length of the long steel bar will be the same each time. Therefore, a limiting baffle is fixedly installed inside the clamp at the discharge end, so that the long steel bar cannot be pushed further after being manually pushed to one side of the limiting baffle. This ensures that the pushing length of the long steel bar is the same each time. However, this makes it impossible to push the long steel bar against the short steel bar to discharge it. The cut short steel bar must be manually removed from the clamp to discharge it. However, this discharge process is not only slow, but the sharp cutting surface of the short steel bar can also easily cut the operator's hands. In addition, since the cutting and segmenting of the round steel bar is continuous, the circular saw is not turned off. It is very dangerous for the operator to discharge the round steel bar in the area close to the circular saw, as they are likely to be injured by the running circular saw. Summary of the Invention

[0004] This invention provides a metal part cutting mechanism based on injection molds, which solves the technical problem in related technologies that it is inconvenient to discharge the cut round steel.

[0005] This invention provides a metal part cutting mechanism based on an injection mold, including a processing table. A circular cutting mechanism, a clamping mechanism, and a first discharge mechanism are fixedly mounted on the top of the processing table. The clamping mechanism includes several clamping support frames symmetrically fixedly connected to the top of the processing table. A first cylinder is fixedly mounted on each clamping support frame, and a first arc-shaped clamping plate is fixedly mounted on the output end of the first cylinder. The first discharge mechanism includes two slide rails fixedly connected to the top of the processing table near the circular cutting mechanism. A flipping support frame is slidably connected inside the slide rails. A second cylinder is rotatably connected to the flipping support frame, and a second arc-shaped clamping plate is fixedly connected to the output end of the second cylinder. The two second arc-shaped clamping plates are positioned at the same axis as the central axis of the several first arc-shaped clamping plates. Each of the second arc-shaped clamping plates has a limit baffle fixedly connected to the side away from the first cylinder. A first motor is fixedly installed on the side of the flipping support frame away from the second arc-shaped clamping plate. The output end of the first motor is fixedly connected to the side of the second cylinder closest to it. A U-shaped plate is fixedly connected to the top of the two flipping support frames. A support baffle is fixedly connected to the side of the processing table close to the U-shaped plate. A third cylinder is fixedly installed on the side of the support baffle away from the U-shaped plate. The output end of the third cylinder passes through the support baffle and connects to the side of the U-shaped plate. A discharge chute is opened at the top of the processing table directly below the second arc-shaped clamping plate. A guide pipe is set below the processing table on the side close to the discharge chute. Supports are fixedly connected to both sides of the guide pipe. The supports are connected to the processing table.

[0006] In a preferred embodiment, the lengths of the first arc-shaped clamps are all less than the lengths of the second arc-shaped clamps, and the lengths of the second arc-shaped clamps are less than the lengths of the discharge chute.

[0007] In a preferred embodiment, the feed tube is in a vertical position and is cylindrical, with an inner diameter larger than the diameter of the round steel.

[0008] In a preferred embodiment, the feed tube includes a buffer plate and a receiving groove is provided inside the feed tube. One end of the buffer plate extends into the receiving groove, and the two sides of the buffer plate are rotatably connected to the inner wall of the feed tube. A torsion spring is provided at the rotatable connection between the buffer plate and the feed tube. One end of the torsion spring is fixedly connected to the buffer plate, and the other end is fixedly connected to the feed tube.

[0009] In a preferred embodiment, the length of the receiving groove is greater than the length of the buffer plate, the rotatable connection between the buffer plate and the guide tube is located at the upper end of the receiving groove, the width of the buffer plate is less than the width of the receiving groove, and the corners of the buffer plate end are rounded.

[0010] In a preferred embodiment, the circular cutting mechanism further includes a conveying mechanism and a second discharge mechanism. The second discharge mechanism includes a connecting frame located below the processing table near the discharge trough. A second motor is fixedly installed on one side of the connecting frame, one side of the guide pipe is rotatably connected to the connecting frame, and the other side of the guide pipe is connected to the output end of the second motor.

[0011] In a preferred embodiment, an arc-shaped groove is provided at the bottom inner side of the guide tube, the arc-shaped groove penetrates the bottom of the guide tube, and an arc-shaped baffle is slidably connected inside the arc-shaped groove. The bottom end of the arc-shaped baffle passes through the arc-shaped groove and is connected to the first bevel gear. The second discharge mechanism includes a bottom cover fixedly connected to the bottom outer side of the guide tube. The bottom inner side of the bottom cover and the middle of the bottom outer side of the guide tube are both rotatably connected to the first bevel gear. A second bevel gear is rotatably connected to one side inside the bottom cover. The second bevel gear meshes with the two first bevel gears. A third motor is fixedly installed on the outside of the bottom cover near the second bevel gear. The output end of the third motor passes through the bottom cover and is connected to the second bevel gear. The connecting frame is parallel to the support baffle. The center of the arc-shaped groove and the center of the two first bevel gears are at the same position.

[0012] In a preferred embodiment, the arc-shaped baffle further includes a mating plate, which is fixedly connected to the side of the arc-shaped baffle near the third motor. The side of the buffer plate near the arc-shaped baffle is an inclined surface, and the mating plate forms a wedge-shaped fit with the arc-shaped baffle through the inclined surface.

[0013] In a preferred embodiment, the connecting frame is provided with a plurality of slots at equal intervals, and a limit rod is fixedly connected to the top of the buffer plate, the limit rod and the slots forming a limiting abutment engagement.

[0014] In a preferred embodiment, a first inclined groove is provided at the bottom of the feed tube, and a second inclined groove is provided on the outer wall of the arc-shaped baffle. The first inclined groove and the second inclined groove correspond to each other, and a limiting round bar is provided inside the first inclined groove, which is slidably connected to the first inclined groove and the second inclined groove.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. Due to the design of the first discharge structure, this invention adopts a "horizontal movement, vertical flipping, and guided discharge" assembly line operation mode, which shortens the transfer time after the round steel is cut. After the cutting is completed, the third cylinder pulls the flipping support frame to slide along the slide rail, which moves the clamped cut round steel away from the long end to avoid interference during flipping. Then, the first motor drives the second cylinder to rotate, flipping the horizontal round steel to a vertical state, so that it is accurately aligned with the discharge chute and guide pipe below. The whole process does not require manual intervention. The automatic discharge is achieved through the linkage of the mechanical structure. Compared with the traditional manual material handling method, this discharge method is more efficient. Especially in continuous cutting scenarios, it can effectively reduce the waiting time of the process and improve the cycle efficiency of the overall production line.

[0017] 2. Due to the inclusion of a receiving trough and a buffer plate, this invention achieves deceleration and buffering of falling round steel bars through the buffer plate assembly inside the guide pipe. The buffer plate is rotatably connected to the receiving trough via a torsion spring. When the round steel bar falls, its bottom end contacts the buffer plate and causes it to flip downwards. The elastic deformation of the torsion spring absorbs the kinetic energy of the fall, reducing the impact speed. Multiple equidistantly distributed buffer plates form a stepped deceleration effect, significantly reducing the impact force of the round steel bar falling from a height onto the conveyor mechanism. This design avoids the problems of round steel bar deformation and conveyor belt damage caused by traditional hard contact, reduces cost losses due to workpiece scrapping and equipment maintenance, and ensures the dimensional accuracy of subsequent processing.

[0018] 3. This invention constructs a multi-mechanical interlocking mechanism through the coordinated design of the insertion plate, limiting rod, slot, inclined groove, and limiting round bar, which significantly improves the reliability and operational safety of the equipment. When the guide tube is in a vertical state, the limiting round bar is simultaneously embedded in the first and second inclined grooves. The rigid limiting of the arc-shaped baffle is achieved by the contact between the slider and the inclined groove, which effectively prevents it from accidentally opening during the fall of the round steel, ensuring that the round steel can fall accurately into the guide tube. When the limiting rod at the top of the buffer plate is not pressed by the round steel, it extends into the slot of the connecting frame to form a mechanical lock, avoiding the second motor from being accidentally started and causing the guide tube to flip prematurely, thus eliminating the risk of the round steel not being able to be supported from the source.

[0019] 4. Due to the setting of the limiting baffle and the clamping mechanism, the present invention ensures the stability of the cutting length each time through the coordinated design of the limiting baffle and the clamping mechanism. After the operator puts the round steel into the clamping end, its end abuts against the limiting baffle. The first cylinder and the second cylinder drive the arc-shaped clamping plate to achieve rigid clamping, so that the round steel remains in a fixed position during the cutting process. Since the relative distance between the limiting baffle and the round cutting mechanism is constant, and the round steel avoids axial movement through the multi-point positioning of the arc-shaped clamping plate, the error of the cutting length each time can be controlled within a very small range. This design effectively solves the length deviation problem caused by traditional manual feeding. It is especially suitable for scenarios that require batch processing of round steel of the same specification, and significantly improves the consistency of product size and the adaptability of subsequent assembly.

[0042] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, a metal part cutting mechanism based on an injection mold includes a processing table 1. A circular cutting mechanism 2, a clamping mechanism 4, and a first discharge mechanism 5 are fixedly mounted on the top of the processing table 1. The clamping mechanism 4 includes several clamping support frames 41 symmetrically and fixedly connected to the top of the processing table 1. A first cylinder 42 is fixedly mounted on the clamping support frame 41, and a first arc-shaped clamping plate 43 is fixedly mounted on the output end of the first cylinder 42. The first discharge mechanism 5 includes two slide rails 51 fixedly connected to the top of the processing table 1 near the circular cutting mechanism 2. A flipping support frame 52 is slidably connected inside the slide rails 51. A second cylinder 53 is rotatably connected to the flipping support frame 52, and a second arc-shaped clamping plate 54 is fixedly connected to the output end of the second cylinder 53. The two second arc-shaped clamping plates 54 are at the same position as the central axis of the several first arc-shaped clamping plates 43. The two second arc-shaped clamping plates 54 clamp... Limiting baffles 55 are fixedly connected to the side of the holding end away from the first cylinder 42. A first motor 56 is fixedly installed on the side of the flipping support frame 52 away from the second arc-shaped clamp 54. The output end of the first motor 56 is fixedly connected to the side of the second cylinder 53 nearby. A U-shaped plate 57 is fixedly connected to the top of the two flipping support frames 52. A support baffle 58 is fixedly connected to the side of the processing table 1 near the U-shaped plate 57. A third cylinder 59 is fixedly installed on the side of the support baffle 58 away from the U-shaped plate 57. The output end of the third cylinder 59 passes through the support baffle 58 and is connected to the side of the U-shaped plate 57. A discharge chute 510 is opened at the top of the processing table 1 directly below the second arc-shaped clamp 54. A guide pipe 511 is provided below the processing table 1 near the discharge chute 510. Supports are fixedly connected to both sides of the guide pipe 511 and the supports are connected to the processing table 1.

[0044] It should be further explained that the circular cutting mechanism 2 includes a circular saw and a horizontal drive assembly. The circular saw has a rotating saw blade inside. A coolant injection pipe is fixed in the cutting area near the circular saw blade. The end of the coolant injection pipe away from the saw blade is connected to the output end of the liquid pump. The input end of the liquid pump is connected to the cooling storage tank. The circular saw and the horizontal drive assembly are connected to drive the circular saw to move along the width direction of the processing table 1. The horizontal drive assembly can also be a linear drive mechanism such as a cylinder or a hydraulic cylinder. The spacing between several adjacent clamping support frames 41 is the same. The length of several first arc-shaped clamping plates 43 is less than the length of the second arc-shaped clamping plate 54. The length of the second arc-shaped clamping plate 54 is less than the length of the discharge chute 510. The guide pipe 511 is in a vertical state and is cylindrical. The inner diameter of the guide pipe 511 is greater than the diameter of the round steel.

[0045] In actual use, the operator drives the first cylinder 42 and the second cylinder 53 to move the first arc-shaped clamping plate 43 and the second arc-shaped clamping plate 54 away from each other. Then, the round steel is placed between the first arc-shaped clamping plate 43 and the second arc-shaped clamping plate 54. The operator then drives the first cylinder 42 and the second cylinder 53 again to move the first arc-shaped clamping plate 43 and the second arc-shaped clamping plate 54 closer together, thus clamping the round steel. During this process, the end of the round steel contacts one side of the limiting baffle 55. Then, the circular saw is moved horizontally by the horizontal drive assembly to cut the clamped round steel. During cutting, the coolant injection pipe directly sprays coolant onto the part of the saw teeth that contacts the steel bar, thus preventing the cutting debris from melting and adhering to the saw blade surface due to overheating during cutting. After the round steel is cut... By driving the third cylinder 59 to pull the connected spiral plate 57 away from the first arc-shaped clamping plate 43, the spiral plate 57 will drive the connected flipping support frame 52 to slide inside the slide rail 51, thereby causing the clamped cut round steel to move away from the first arc-shaped clamping plate 43 along the length of the worktable until it slides to the end of the slide rail 51 away from the first arc-shaped clamping plate 43. This ensures that the horizontal movement distance is constant each time, avoiding the situation where the end of the round steel does not correspond to the top of the guide tube 511 due to insufficient horizontal movement distance. Subsequently, the first motor 56 drives the second cylinder 53 and the second arc-shaped clamping plate 54 to rotate. The rotation of the second arc-shaped clamping plate 54 causes the round steel it clamps to rotate synchronously, rotating the round steel from a horizontal state to a vertical state. During this process, due to the output... The length of the feed trough 510 is greater than the length of the second arc-shaped clamp 54, so the discharge trough 510 can provide sufficient space for the second arc-shaped clamp 54 to flip. At this time, the end of the round steel in the vertical state away from the discharge trough 510 corresponds to the top of the guide pipe 511, that is, the cut round steel is located directly above the guide pipe 511. Then, the clamping of the cut round steel is released by the contraction of the second cylinder 53. At this time, the clamped round steel will fall into the guide pipe 511 and be collected by the guide pipe 511. Then it is manually removed and transferred to the next processing equipment. Then the first motor 56 resets, the third cylinder 59 resets, and then drives several first cylinders 42 and second cylinders 53 to slightly loosen the clamping of the round steel. Then the operator pushes the round steel so that the round steel is in the first... The clamping ends of the first arc-shaped clamping plate 43 and the second arc-shaped clamping plate 54 slide until the end of the round steel touches one side of the limiting baffle 55 again. Then, the round steel is clamped and fixed by the extension of the first cylinder 42 and the second cylinder 53. The round steel is cut in this way. Since the distance between the limiting baffle 55 and the circular saw remains unchanged, the length of the round steel cut by the limiting baffle 55 each time is the same. In addition, the assembly line-type discharge method of horizontally moving the cut round steel, flipping it from horizontal to vertical state, and clamping and releasing it makes the discharge of the round steel more convenient and faster. This method can also transfer the cut round steel from the area near the circular saw to below the processing table 1, making the process of assisting the operator in the discharge safer.

[0046] In the above embodiment, when the round steel enters the guide tube 511, the two sets of second arc-shaped clamps 54 move away from each other and directly release the clamps on the round steel. Under the action of gravity, the round steel falls directly into the guide tube 511. Since the round steel is a solid metal material, its own weight is relatively heavy, so the impact generated by free fall is relatively large. If it falls directly into the guide tube 511, it will cause the guide tube 511 to be deformed by impact, or even directly damaged. Therefore, in order to solve the above technical problem, in another embodiment of the present invention, the guide tube 511 further includes a buffer plate 5112. A receiving groove 5111 is opened in the guide tube 511. One end of the buffer plate 5112 extends into the receiving groove 5111, and the two sides of the buffer plate 5112 are rotatably connected to the inner wall of the guide tube 511. A torsion spring is provided at the rotatable connection between the buffer plate 5112 and the guide tube 511. One end of the torsion spring is fixedly connected to the buffer plate 5112, and the other end is fixedly connected to the guide tube 511.

[0047] It should be added that, such as Figure 10 and Figure 11 As shown, the receiving groove 5111 is provided in multiple sets and is symmetrically arranged along the central axis of the guide tube 511. Each receiving groove 5111 is equipped with a buffer plate 5112. The length of the receiving groove 5111 is greater than the length of the buffer plate 5112. The rotatable connection between the buffer plate 5112 and the guide tube 511 is located at the upper end of the receiving groove 5111. The width of the buffer plate 5112 is less than the width of the receiving groove 5111. The corners of the buffer plate 5112 are rounded.

[0048] In actual use, after the first motor 56 adjusts the clamped round steel to a vertical position, the second cylinder 53 retracts, releasing the round steel from its clamp. At this time, the round steel will fall into the guide tube 511. During this process, the bottom end of the round steel will contact the buffer plate 5112, which is reset by the torsion spring and is in a horizontal position. The buffer plate 5112 will then flip downwards due to the weight of the round steel. Under the impact of the round steel, the buffer plate 5112 will deflect around the hinge point, simultaneously causing the torsion spring to undergo elastic torsional deformation. During this process, the torsion spring absorbs and dissipates the kinetic energy of the falling round steel through elastic deformation, converting the impact kinetic energy into elastic potential energy and a small amount of frictional loss, thereby significantly reducing the impact force and falling speed of the round steel, achieving the buffering, deceleration and limiting effect on the round steel. Multiple equidistant buffer plates 5112 can improve the buffering effect when the round steel falls, so that the round steel can fall slowly and steadily to the bottom of the guide tube 511, so that neither the bottom of the guide tube 511 nor the round steel will be damaged.

[0049] In order to facilitate the delivery of the cut round steel to the designated position, in another embodiment of the present invention, the round cutting mechanism 2 further includes a conveying mechanism 3 and a second discharge mechanism 6. The second discharge mechanism 6 includes a connecting frame 61 below the processing table 1 near the discharge trough 510. A second motor 62 is fixedly installed on one side of the connecting frame 61. One side of the guide pipe 511 is rotatably connected to the connecting frame 61, and the other side of the guide pipe 511 is connected to the output end of the second motor 62.

[0050] It should be added that, such as Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, the conveying mechanism 3 in this embodiment can be a conveyor belt conveyor, which is the prior art and will not be described in detail. The guide pipe 511 has an opening on one side of the flipping direction, and the width of the opening is greater than the diameter of the round steel.

[0051] In actual use, after the round steel falls into the guide tube 511 through several buffer plates 5112, the guide tube 511 is rotated by the second motor 62, thereby turning the opening on one side of the guide tube 511 to face downwards. That is, after the guide tube 511 is rotated from a vertical state to a horizontal state, the round steel inside the guide tube 511 will fall into the conveyor belt in the conveying mechanism 3 through the opening, and then be conveyed to the next processing stage by the conveyor belt.

[0052] In the above embodiment, the second cylinder 53 retracts to release the clamp on the round steel, allowing it to fall into the guide tube 511. The second motor 62 then rotates the guide tube 511, causing it to fall through an opening on one side and finally to the top of the conveying mechanism 3. However, as the guide tube 511 rotates from a vertical to a horizontal position, it gradually tilts. This tilting causes the interior to tilt synchronously. In other words, once the guide tube 511 has rotated to a certain tilt angle, the round steel inside will disengage through the opening on one side. Under the influence of gravity and the weight of the round steel itself, the round steel will fall heavily onto the conveying mechanism 3, causing it to spread out on the conveying mechanism 3. This prevents the round steel from falling smoothly onto the top of the conveying mechanism 3, or it may fall directly onto the outside of the conveying mechanism 3. Therefore, in order to solve the above-mentioned technical problem, in another embodiment of the present invention, the second discharge mechanism 6 further includes an arc-shaped baffle 64 and a driving member. An arc-shaped groove 63 is provided inside the guide pipe 511. The arc-shaped baffle 64 is located inside the arc-shaped groove 63. The driving member is connected to the arc-shaped baffle 64 and is used to drive the arc-shaped baffle 64 to move along the groove direction of the arc-shaped groove 63.

[0053] It should be noted that the driving component can be a linear driving assembly such as a motor or cylinder. The arc-shaped chute 63 passes through the guide tube 511, and the bottom end of the arc-shaped baffle 64 passes through the arc-shaped chute 63 and is connected to the output end of the driving component.

[0054] In another embodiment of the present invention, preferably, the driving component includes two vertically symmetrical first bevel gears 66, a second bevel gear 67 meshing between the two first bevel gears 66, a third motor 68 connected to the end of the second bevel gear 67, a bottom cover 65 fixedly connected to the bottom outer side of the guide tube 511, the two first bevel gears 66 being rotatably connected to the bottom end of the guide tube 511 and the inner wall of the bottom cover 65 respectively, the second bevel gear 67 being rotatably connected to the inner wall of the bottom cover 65, the third motor 68 being fixedly installed on the outside of the bottom cover 65, and the bottom ends of two arc-shaped baffles 64 being fixedly connected to the two first bevel gears 66 respectively.

[0055] It should be added that, such as Figure 10 , Figure 11 and Figure 12 As shown, the two arc-shaped slides 63 are symmetrical to the central axis of the guide tube 511. The connecting frame 61 is parallel to the support baffle 58. The two connecting frames 61 are connected to each other by two arc-shaped brackets on the side near the third motor 68. The connecting frame 61 on the side near the support baffle 58 is fixedly connected to the crossbeam on the side of the processing table 1. The arc-shaped slides 63 and the centers of the two first bevel gears 66 are at the same position. The arc length of the arc-shaped slides 63 is greater than the arc length of the opening portion blocked by the arc-shaped baffle 64. The bottom end of the arc-shaped baffle 64 passes through the arc-shaped slides 63 and is connected to the first bevel gears 66.

[0056] In actual use, after the cut round steel enters the guide tube 511, the second motor 62 drives the guide tube 511 to rotate, supported by the connecting frame 61, until the guide tube 511 rotates to a horizontal position. Then, the third motor 68 drives the second bevel gear 67 to rotate. At this time, the second bevel gear 67 drives the two meshing first bevel gears 66 to rotate. Since the two first bevel gears 66 mesh with the top and bottom ends of the second bevel gear 67 respectively, and the linear velocity directions of the top and bottom ends of the same gear are opposite, the two meshing gears rotate in opposite directions. Therefore, the force directions of the two first bevel gears 66 are opposite, and their rotation directions are also opposite. A bevel gear 66 will drive the two arc-shaped baffles 64, which are fixedly connected to the two first bevel gears 66, to rotate together inside the arc-shaped chute 63. This will make the opening of the guide tube 511 larger, and the round steel inside the guide tube 511 will fall out of the guide tube 511 through its opening and fall to the top of the conveyor belt in the conveying mechanism 3. Then it will be conveyed by the conveying mechanism 3 to the next processing equipment. This setting allows the opening on one side of the guide tube 511 to be blocked by the arc-shaped baffles 64 when the guide tube 511 is not flipped to a horizontal state. Only when the guide tube 511 is flipped to a horizontal state will the arc-shaped baffles 64 open to allow the round steel to be discharged. This ensures that the round steel falls smoothly to the top of the conveying mechanism 3.

[0057] In the above embodiment, the impact force of the round steel is buffered during its descent by the rotation of the buffer plate 5112 and the torsion spring. That is, when the round steel is completely inside the guide tube 511, the buffer plate 5112 will abut against the surface of the round steel due to the elastic force of the torsion spring. Since the torsion spring has a certain elastic force and there are multiple sets of buffer plates 5112, the multiple sets of buffer plates 5112 are equivalent to clamping the round steel inside the guide tube 511. When the guide tube 511 rotates from a vertical state to a horizontal state, although the movement of the arc-shaped baffle 64 opens the side opening of the guide tube 511, the round steel is subjected to multiple buffers. Under the influence of the contact and clamping of plate 5112, the round steel may not be able to detach from the horizontal guide tube 511, thereby affecting the transfer operation of the round steel to the conveyor and the output of the cut round steel. Therefore, in order to solve this technical problem, in another embodiment of the present invention, the arc-shaped baffle 64 further includes a fitting plate 641. The fitting plate 641 is fixedly connected to the side of the arc-shaped baffle 64 near the third motor 68. The side of the buffer plate 5112 near the arc-shaped baffle 64 is an inclined surface. The fitting plate 641 forms a wedge fit with the arc-shaped baffle 64 through the inclined surface.

[0058] It should be added that, such as Figure 10 , Figure 11 , Figure 13 and Figure 14 As shown, the buffer plate 5112 has a trapezoidal structure. When the round steel is inside the guide tube 511, the buffer plate 5112 is tilted downward.

[0059] In actual use, when the feed tube 511 is in a horizontal state and the round steel inside needs to be discharged, the third motor 68 drives the two arc-shaped baffles 64 to open. During this process, the end of the insert plate 641 away from the opening of the feed tube 511 will rotate along the surface of the round steel until the end of the insert plate 641 abuts against the gap between the round steel and the buffer plate 5112. Since the buffer plate 5112 is trapezoidal and its two sides are inclined, after the insert plate 641 contacts the side of the buffer plate 5112, It will slide along the inclined surface of the buffer plate 5112, and the insertion plate 641 will continue to extend into the gap between the buffer plate 5112 and the round steel, thereby pushing the buffer plate 5112 to continue to flip deeper into the receiving groove 5111. Finally, the insertion plate 641 replaces the round steel to resist the buffer plate 5112. At that time, because the buffer plate 5112 does not contact the outside of the round steel, the round steel will not be stuck by the buffer plate 5112 when it is discharged, thus making the process of the round steel leaving the guide pipe 511 smoother.

[0060] In another embodiment of the present invention, the connecting frame 61 is further provided with a plurality of slots 10 at equal intervals, and the top end of the buffer plate 5112 is fixedly connected to a limiting rod 11, which forms a limiting abutment cooperation with the slots 10.

[0061] It should be added that, such as Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown, the upper part of the receiving groove 5111 passes through the guide tube 511. When the buffer plate 5112 is in a horizontal state, one end of the limiting rod 11 extends into the slot 10. When the buffer plate 5112 is tilted downward, the limiting rod 11 is outside the slot 10.

[0062] In actual use, before the round steel enters the guide tube 511, the limiting rod 11 and the slot 10 form a stop-stop engagement. Therefore, when the second motor 62 is accidentally started, the second motor 62 cannot drive the guide tube 511 to rotate. So when the round steel does not enter the guide tube 511, the guide tube 511 cannot rotate. Therefore, when there is no round steel inside the guide tube 511, it always remains vertical.

[0063] When the round steel enters the guide tube 511, several buffer plates 5112 will be pressed down and flipped. At that time, the limit rod 11 and the slot 10 will no longer be in contact. The second motor 62 can then drive the guide tube 511 to flip. So when the insertion plate 641 replaces the round steel to contact the buffer plate 5112, the limit rod 11 will also be tilted upwards during the process of the guide tube 511 returning to a vertical state, thus avoiding contact with the connecting frame 61. Therefore, the contact of the insertion plate 641 with the buffer plate 5112 allows the guide tube 511 to cooperate with the reset process after unloading.

[0064] In another embodiment of the present invention, a first inclined groove 7 is provided at the bottom of the guide tube 511, and a second inclined groove 8 is provided on the outer wall of the arc-shaped baffle 64. The first inclined groove 7 and the second inclined groove 8 correspond to each other, and a limiting round bar 9 is provided inside the first inclined groove 7. The limiting round bar 9 is slidably connected to the first inclined groove 7 and the second inclined groove 8.

[0065] It should be added that, by Figure 11 , Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 17 As shown, when the guide tube 511 is in a vertical state, the first inclined groove 7 is above the second inclined groove 8. At this time, the limiting rod 9 is inside the second inclined groove 8, and the top of the limiting rod 9 extends into the first inclined groove 7. At this time, the arc-shaped baffle 64 will be unable to slide inside the arc-shaped chute 63 because the limiting rod 9 is in contact with and limited by the first inclined groove 7. When the guide tube 511 is in a horizontal state, the second inclined groove 8 is above the first inclined groove 7. At this time, the limiting rod 9 will slide down into the first inclined groove 7 below due to its own gravity. At this time, there is no contact between the limiting rod 9 and the second inclined groove 8, so the arc-shaped baffle 64 can slide inside the arc-shaped chute 63. The diameter of the limiting rod 9 is smaller than the inner diameter of the first inclined groove 7 and the second inclined groove 8.

[0066] In actual use, after the guide tube 511 is rotated from a vertical state to a horizontal state by the second motor 62, the arc-shaped baffle 64 can slide inside the arc-shaped chute 63. At that time, the arc-shaped baffle 64 can be driven by the third motor 68 to slide along the arc-shaped chute 63, so that the two arc-shaped baffles 64 gradually move away from each other. At that time, the round steel can be separated from the inside of the guide tube 511 and fall onto the conveying mechanism 3. When the guide tube 511 returns to the vertical state, the arc-shaped baffle 64, which is in the away state, will be driven to return to the vertical state by the third motor 68. After the arc-shaped baffle 64 returns to the vertical state, the limiting round bar 9 inside the first inclined groove 7 will slide back into the second inclined groove 8 due to gravity, so that the arc-shaped baffle 64 is again resisted and limited and cannot rotate. At that time, the buffer plate 5112 will also return to the vertical state due to the loss of resistance and limitation. At the same time, the limiting rod 11 will return to the slot 10 due to the return of the buffer plate 5112. 1. The guide tube 511 is repositioned, preventing it from being flipped. This design avoids the second motor 62 from accidentally starting and rotating the guide tube 511 during processing, thus preventing the guide tube 511 from flipping and leaving no guide tube to receive the round bar when it exits. It also prevents the third motor 68 from accidentally starting and opening the arc baffle 64 when the guide tube 511 is in a vertical position, which could damage the bottom of the guide tube 511 if the round bar enters the guide tube 511 without the buffer plate 5112. The flipping of the guide tube 511 restricts the rotation of the arc baffle 64, ensuring close cooperation between the two. If one part malfunctions, the subsequent components that are restricted by it will also be unable to operate, making troubleshooting in the later stages of the equipment much faster.

[0067] In summary, the guide tube 511 cannot rotate when the round steel bar has not entered its interior. Once the round steel bar enters the guide tube 511, it can rotate. Simultaneously, the guide tube 511 can also rotate when the arc-shaped baffle 64 contacts the buffer plate 5112. Only when the guide tube 511 rotates to a horizontal position can the arc-shaped baffle 64 rotate away from each other due to the loss of its limiting position. When the guide tube 511 is horizontal, the arc-shaped baffle 64 opens, allowing the round steel bar to exit. Simultaneously, the arc-shaped baffle 64 replaces the round steel bar in contacting the buffer plate 5112, at which point the guide tube 511 can rotate back to its original position. When the guide tube 511 returns to a vertical position... After the initial state, because the first inclined groove 7 and the second inclined groove 8 do not correspond, the arc-shaped baffle 64 is not yet limited. At this time, the arc-shaped baffle 64 can still be reset and rotated. After the arc-shaped baffle 64 is reset, the buffer plate 5112 is reset by the spring force of the torsion spring because it does not have any contact. When the buffer plate 5112 returns to the horizontal state, the guide tube 511 will re-contact and limit the engagement with the slot 10. At that time, the guide tube 511 cannot rotate. Therefore, the contact between the insertion plate 641 and the buffer plate 5112 can determine whether the guide tube 511 flips or not. At the same time, the flipping of the guide tube 511 can determine whether the arc-shaped baffle 64 rotates or not. The two are related to each other and cooperate with each other. Neither can be omitted.
