Description

Technical Field

[0001] The invention relates to the technical field of magnesium ingot fixing, and in particular to a quick fixing device for a magnesium ingot cutting machine. Background Art

[0002] Magnesium ingots are bulk metal materials made of pure magnesium or magnesium alloys. They are lightweight, corrosion-resistant, and have high specific strength. They are a new type of industrial metal developed in the 20th century. Magnesium ingots, primarily composed of the element magnesium (Mg), are formed by smelting magnesium ore and casting, and are widely used in modern industrial manufacturing. Before they can be processed into magnesium powder, the ingots must be chipped. Chipping is the process of converting magnesium alloy ingots into scrap through mechanical processing (such as cutting and planing).

[0003] Since the cutting blade will generate a large impact force when cutting the magnesium ingot, the magnesium ingot needs to be installed in a fixing device before cutting. For example, the patent document entitled "Clamping device for metal cutting with flipping structure" with authorization announcement number CN220278475U, when in use, is powered by an external power supply for the controller and the motor. When the metal to be cut needs to be clamped and flipped, the movable plate is pulled so that the two ends of the metal are respectively placed between the two first square plates and the second square plates. The knob is rotated to lower the clamping column until the clamping column fits the metal. The knob is continued to be rotated to clamp the metal between the second square plate and the clamping column. The two motors are controlled to start synchronously through the controller to drive the rotating shaft to rotate, so that the rotating plate drives the metal to flip.

[0004] With regard to the above-mentioned related technologies, when clamping the metal block, the operator needs to turn the knob forward to make the clamping column press the metal block. When replacing the metal block, the operator needs to reverse the knob to loosen the metal block. When the pressure of the clamping block on the metal block is large, the friction between the knob and the threaded hole on the first square plate increases, and the torque required for the operator to reverse the knob increases. For the processing of large quantities of metal blocks, the reciprocating rotation of the knob is cumbersome. Summary of the Invention

[0005] In view of this, the present invention provides a quick fixing device for a magnesium ingot cutting machine, aiming to solve the problem of complicated metal block fixing steps.

[0006] In order to solve the above technical problems, the present invention provides a quick fixing device for a magnesium ingot cutting machine, comprising a support shell; a support shaft is rotatably connected in the support shell, and a support ring and a pressure ring for supporting the magnesium ingot are sleeved on the support shaft, and a guide block and a support block are provided on the support ring; the support shell is fixedly connected to a limit ring on the inner side surface near the pressure ring, the limit ring is hinged with an unlocking ring, and the inner side surface of the support shell is hinged with a linear drive 1 through a connecting frame, and the output shaft of the linear drive 1 is hinged with the unlocking ring; the pressure ring is provided with a slide groove along the radial direction, and a pressure piece for fixing the magnesium ingot to the pressure ring is slidingly provided in the slide groove, and a limit rod located inside the limit ring is provided on the pressure piece, and the inner bottom surface of the slide groove is connected with a support spring capable of pushing the pressure piece to move outside the slide groove; the support shell is provided with a driving mechanism, and the driving mechanism is used to drive the support ring and the pressure ring to rotate, and can push the pressure ring to move close to the support ring.

[0007] By adopting the above technical solution, after the magnesium ingot is replaced, the driving mechanism drives the pressure ring to operate at a low speed. The pressure ring continues to drive the limit rod to rotate, and the limit rod rotates along the inner side of the unlocking ring to the limit ring. The limit ring pushes the limit rod to move inside the limit ring, and the pressure piece moves synchronously with the limit rod to press the magnesium ingot to the pressure ring. The unlocking ring and the support spring are used to automatically loosen the magnesium ingot, and when the pressure piece rotates around the support shaft for one circle, the pressure piece is loosened one by one and tightened again to realize the unloading of the remaining magnesium ingots and the loading of the unprocessed magnesium ingots. This process simplifies the operation of the operator and realizes the function of the magnesium ingot cutting machine to quickly fix the magnesium ingot, which is conducive to the efficient cutting of magnesium ingots.

[0008] Optionally, the pressing member includes a sliding block and a pressing plate hinged to each other, the pressing plate is L-shaped, and is used to press and fix the magnesium ingot to the pressing ring, the sliding block is slidably connected to the outside of the limit rod, a tension spring is connected between the pressing plate and the pressing ring, and a guide roller is rotatably connected in the slide groove, and the guide roller is arranged between the inner side of the slide groove and the pressing plate.

[0009] By adopting the above technical solution, when the limit rod rotates to the notch of the limit ring, the support spring pushes the sliding block to move to the outside of the slide groove, and the pressure plate moves out of the slide groove synchronously with the sliding block. The guide roller abuts the outer side surface of the pressure block, and the pressure block rotates around the guide roller. At this time, the tension spring pulls the pressure plate to rotate, so that the protruding pressure part at the upper end of the L-shaped pressure plate rotates away from the magnesium ingot, so that the operator can replace the magnesium ingot.

[0010] Optionally, the guide block is fixedly connected to the support ring, the lower bottom surface of the support block is fixedly connected to a transmission rod, the transmission rod is hinged to the support ring through a rotating pin, the transmission rod is provided with a waist-shaped groove, and the limit rod is slidably set in the waist-shaped groove.

[0011] By adopting the above technical solution, when the pressing piece moves toward the outside of the slide groove to loosen the magnesium ingot, the pressing piece drives the limiting rod to move radially toward the outside of the support ring. While the limiting rod slides in the waist-shaped groove, it drives the transmission rod to rotate around the rotating pin. The guide block rotates synchronously with the limiting rod away from the side wall of the magnesium ingot, increasing the gap between the guide block and the support block to facilitate the operator to remove and install the magnesium ingot.

[0012] Optionally, the support block is threadedly connected with an adjusting bolt, one end of the adjusting bolt close to the guide block is threadedly connected with a pressing block, and the magnesium ingot is located between the guide block and the pressing block.

[0013] Optionally, a limit block capable of abutting against the outer side surface of the magnesium ingot is fixedly connected to the upper surface of the press ring, and the limit block is arranged at one end of the press piece along the circumference of the press ring.

[0014] Optionally, the relative inner side surfaces of the pressing block and the guide block are rotatably connected to support rollers, and the support rollers are arranged perpendicular to the support shaft.

[0015] By adopting the above technical solution, the magnesium ingot abuts against the support roller, and the sliding friction between the pressing block and the magnesium ingot and between the guide block and the magnesium ingot is converted into rotational friction, thereby improving the smoothness of the magnesium ingot feeding and reducing the wear of the magnesium ingot.

[0016] Optionally, a sliding sleeve on the outer side of the limiting rod is provided with a material-blocking block, which can support the magnesium ingot after cutting, and a reset spring is fixedly connected between the pressure ring and the material-blocking block.

[0017] By adopting the above technical solution, the abutment block abuts against the lower bottom surface of the remaining magnesium ingot after cutting, preventing the magnesium ingot from directly falling off the pressing ring and falling to the bottom of the supporting shell after the pressing piece loosens. This is conducive to the operator replacing the magnesium ingot in an orderly manner.

[0018] Optionally, a receiving groove is provided on the side of the pressing ring close to the supporting ring, and the resisting block can move into the receiving groove.

[0019] Optionally, an end cover is hingedly connected to the upper side wall of the support shell, and a second linear drive is hingedly connected between the end cover and the support shell.

[0020] Optionally, the driving mechanism includes a rotating source one fixedly connected to the outer side surface of the supporting shell, the output shaft of the rotating source one is fixedly connected to the supporting shaft, the supporting ring is fixedly connected to the supporting shaft, the pressing ring is slidingly connected to the supporting shaft, the pressing ring is rotatably connected to the outer side surface away from the supporting ring, the outer side surface of the supporting shell is fixedly connected to a linear driver three, and the output shaft of the linear driver three is fixedly connected to the rotating ring.

[0021] In summary, compared with the prior art, the present invention has at least one of the following beneficial technical effects:

[0022] 1. The unlocking ring and the support spring are used to realize the automatic loosening of the pressing piece of the magnesium ingot. When the pressing piece rotates around the support shaft for one circle, the pressing piece can loosen multiple magnesium ingots one by one and tighten the magnesium ingots again, so as to realize the unloading of the remaining magnesium ingots and the loading of the unprocessed magnesium ingots. This process simplifies the operation of the operator, realizes the function of the magnesium ingot cutting machine to quickly fix the magnesium ingot, and is conducive to the efficient cutting of magnesium ingots.

[0023] 2. When the pressing piece moves to the outside of the slide to loosen the magnesium ingot, the pressing piece drives the limiting rod to move radially toward the outside of the support ring. While the limiting rod slides in the waist-shaped groove, it drives the transmission rod to rotate around the rotating pin. The guide block rotates synchronously with the limiting rod away from the side wall of the magnesium ingot, increasing the gap between the guide block and the support block to facilitate the operator to remove and install the magnesium ingot.

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the embodiments of the present invention. Figures 1-9 , clearly and completely describe the technical solutions of the embodiments of the present invention.

[0035] This embodiment provides a quick fixing device for a magnesium ingot cutting machine, referring to Figure 1 A quick fixing device for a magnesium ingot cutting machine includes a support housing 1, a support ring 4 and a binder ring 5 for supporting a magnesium ingot 3, and a binder 52 for fastening the magnesium ingot 3. A bracket 18 is fixedly connected to the lower bottom surface of the support housing 1. The bracket 18 stands upright on a horizontal plane. The lower end side wall of the support housing 1 is tapered, and a discharge hole is opened on the lower bottom surface of the support housing 1.

[0036] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 8 and Figure 9The support housing 1 is internally rotatably connected to a support shaft 11. The support ring 4 and the pressure ring 5 are both sleeved on the support shaft 11. Both the support ring 4 and the pressure ring 5 are regular decagons, and the support ring 4 is fixedly connected to the support shaft 11. The pressure ring 5 is axially slidably connected to the support shaft 11 by spline fitting (that is, when the support shaft 11 rotates, the splines provided on its outer arc surface will be in radial holding force with the pressure ring 5, thereby driving the pressure ring 5 to rotate). The support ring 4 is provided with a guide block 41 and a support block 42. There are multiple guide blocks 41 and support blocks 42 and they are distributed in an array along the circumference of the support ring 4. The guide blocks 41 and support blocks 42 are arranged in a one-to-one correspondence, and the magnesium ingot 3 is placed between the guide blocks 41 and support blocks 42. The guide block 41 is detachably connected to the support ring 4 by bolts. When the magnesium ingot 3 moves axially along the support shaft 11 to feed the material, the guide block 41 and support block 42 are used to guide the movement of the magnesium ingot 3. A limit ring 12 is fixedly connected to the inner side of the support housing 1 near the pressure ring 5. The upper end of the limit ring 12 has an opening, and an unlocking ring 13 is hingedly connected to the opening of the limit ring 12. A connecting frame 14 is fixedly connected to the inner side of the support housing 1. A linear actuator 15 is hingedly connected to the connecting frame 14. The output shaft of the linear actuator 15 is hingedly connected to the unlocking ring 13.

[0037] Reference Figure 1 and Figure 4 The pressure ring 5 is provided with a plurality of chutes 51, and the chutes 51 are arranged in a circumferential array along the pressure ring 5 corresponding to the guide blocks 41, and each chute 51 is opened along the radial direction of the pressure ring 5. A pressure piece 52 for pressing and fixing the magnesium ingot 3 to the pressure ring 5 is slidably provided in each chute 51. The pressure piece 52 is provided with a limit rod 53 located inside the limit ring 12, and a shaft sleeve 531 is provided on the outer rotating sleeve of the limit rod 53. The shaft sleeve 531 can replace the limit rod 53 and abut against the inner side surface of the limit ring 12, thereby reducing the friction coefficient between the limit rod 53 and the limit ring 12. A support spring 54 is connected between the inner bottom surface of the chute 51 and the pressure piece 52, and the support spring 54 can push the pressure piece 52 to move to the outside of the chute 51. The support shell 1 is provided with a driving mechanism 6, which is used to drive the support ring 4 and the pressure ring 5 to rotate, and can push the pressure ring 5 to move close to the support ring 4. The inner side surface of the supporting shell 1 is rotatably connected to the cutting blade 2 .

[0038] During the processing of the magnesium ingot 3, the magnesium ingot 3 is placed on the support ring 4 and the pressure ring 5, and the magnesium ingot 3 is located between the pressure piece 52, the guide block 41 and the support block 42. The guide block 41 and the support block 42 do not clamp the magnesium ingot 3. The output shaft of the linear drive 15 extends to push the unlocking ring 13 to rotate and abut against the limiting ring 12, so that the unlocking ring 13 and the limiting ring 12 form a complete circular ring. The limiting rod 53 is located inside the limiting ring 12 and rotates synchronously with the pressure ring 5. At this time, the limiting ring 12 limits the limiting rod 53 from moving radially toward the outside of the limiting ring 12, that is, the limiting ring 12 limits the pressure piece 52 from moving toward the outside of the slide 51 through the limiting rod 53, so that the pressure piece 52 presses the magnesium ingot 3 to the pressure ring 5, and the support spring 54 is in a compressed state. The driving mechanism 6 drives the support ring 4 and the pressure ring 5 to rotate around the support shaft 11, and the magnesium ingot 3 rotates synchronously with the pressure ring 5 and abuts against the cutting knife 2. At the same time, the driving mechanism 6 pushes the pressure ring 5 to move close to the support ring 4. The pressure ring 5 pushes the magnesium ingot 3 along the axial direction of the support shaft 11 to move close to the cutting knife 2 for feeding, thereby realizing cutting of the magnesium ingot 3.

[0039] After the magnesium ingot 3 is cut, the driving mechanism 6 drives the pressing ring 5 to move away from the support ring 4 to reset. The pressing ring 5 pulls the remaining uncut magnesium ingot 3 away from the support ring 4 through the pressing piece 52, and the output shaft of the linear drive 15 pulls the unlocking ring 13 to rotate counterclockwise (refer to Figure 3 ), the opening at the upper end of the limiting ring 12 is opened, and the driving mechanism 6 drives the pressure ring 5 to rotate. When the limiting rod 53 rotates with the limiting ring 12 to the opening, the limiting rod 53 is no longer restricted by the limiting ring 12. The compressed support spring 54 pushes the pressure piece 52 to move radially toward the outside of the chute 51 of the pressure ring 5, causing the pressure piece 52 to loosen the magnesium ingot 3. The limiting rod 53 moves synchronously with the pressure piece 52 toward the outside of the limiting ring 12 and abuts against the inner side of the unlocking ring 13. The operator removes the remaining magnesium ingot 3 on the pressure ring 5 and places the new magnesium ingot 3 to be cut between the pressure ring 5 and the support ring 4.

[0040] After the magnesium ingot 3 is replaced, the driving mechanism 6 drives the pressure ring 5 to operate at a low speed. The pressure ring 5 continues to drive the limiting rod 53 to rotate. The limiting rod 53 rotates along the inner side of the unlocking ring 13 to the limiting ring 12. The limiting ring 12 pushes the limiting rod 53 to move inside the limiting ring 12. The pressure piece 52 moves synchronously with the limiting rod 53 to press the magnesium ingot 3 tightly to the pressure ring 5. Among them, by setting the length of the unlocking ring 13, it is possible to determine the angle at which the pressure ring 5 drives the magnesium ingot 3 to rotate when the limiting rod 53 transitions from the unlocking ring 13 to the limiting ring 12. In this process, the angle at which the magnesium ingot 3 rotates is controlled so that the magnesium ingot 3 and the pressure ring 5 maintain frictional self-locking, preventing the magnesium ingot 3 from sliding relative to the pressure ring 5 before being completely tightened by the pressure piece 52.

[0041] Therefore, the unlocking ring 13 and the support spring 54 are used to cooperate to realize the automatic loosening of the pressing piece 52 to the magnesium ingot 3, and when the pressing ring 5 rotates around the support shaft 11 for one circle, the pressing pieces 52 are loosened one by one and tightened again to realize the unloading of the remaining magnesium ingots 3 and the loading of the unprocessed magnesium ingots 3. This process simplifies the operation of the operator, realizes the function of the magnesium ingot cutting machine to quickly fix the magnesium ingot 3, and is conducive to the efficient cutting processing of the magnesium ingot 3.

[0042] Reference Figure 1 The cutting blade 2 is disposed on the side of the support ring 4 away from the pressure ring 5, and is rotatably connected to the inner side of the support shell 1. A second rotation source 8 is fixedly connected to the outer side of the support shell 1. The output shaft of the second rotation source 8 is fixedly connected to a drive wheel 81. A transmission wheel 82 is rotatably connected to the outer side of the support shell 1. The transmission wheel 82 is coaxially fixedly connected to the cutting blade 2. A conveyor belt 83 is sheathed on the outer sides of the drive wheel 81 and the transmission wheel 82. The second rotation source 8 drives the cutting blade 2 to rotate through the drive wheel 81, the conveyor belt 83, and the transmission wheel 82 in sequence to cut the magnesium ingot 3.

[0043] Reference Figure 4 、 Figure 8 and Figure 9 The binder 52 includes a sliding block 521 and a binder plate 522. The upper end of the sliding block 521 is hinged to the lower end of the binder plate 522 via a second rotating pin 524. The binder plate 522 is L-shaped and is used to press and secure the magnesium ingot 3 to the binder ring 5. The sliding block 521 is slidably mounted on the outside of the limiting rod 53. A tension spring 523 is connected between the binder plate 522 and the binder ring 5. A guide roller 56 is rotatably connected to the chute 51 and is disposed between the inner side of the chute 51 and the binder plate 522. When the limiting rod 53 rotates to the notch of the limiting ring 12, the supporting spring 54 pushes the sliding block 521 to move to the outside of the slide groove 51, and the pressing plate 522 moves out of the slide groove 51 synchronously with the sliding block 521, and the guide roller 56 abuts the outer side surface of the pressing plate 522. At this time, the tension spring 523 pulls the pressing plate 522 to rotate counterclockwise around the rotating pin 2 524, so that the pressing part 525 protruding from the upper end of the L-shaped pressing plate 522 rotates away from the magnesium ingot 3, so that the operator can replace the magnesium ingot 3.

[0044] Reference Figure 5 and Figure 6The lower bottom surface of the support block 42 is fixedly connected to a transmission rod 43, which is hinged to the support ring 4 through a rotating pin 431. The transmission rod 43 is provided with a waist-shaped groove 432, and the limiting rod 53 is slidably set in the waist-shaped groove 432. When the pressing piece 52 moves toward the outside of the slide 51 to loosen the magnesium ingot 3, the pressing piece 52 drives the limiting rod 53 to move radially toward the outside of the support ring 4. While sliding in the waist-shaped groove 432, the limiting rod 53 drives the transmission rod 43 to rotate clockwise around the rotating pin 431. The support block 42 rotates synchronously with the limiting rod 53 away from the side wall of the magnesium ingot 3, increasing the gap between the guide block 41 and the support block 42 to facilitate the operator to remove and install the magnesium ingot 3.

[0045] Reference Figure 6 The support block 42 is threadedly connected to an adjusting bolt 44. The end of the adjusting bolt 44, which is closest to the guide block 41, is threadedly connected to a pressure block 45. The magnesium ingot 3 is positioned between the guide block 41 and the pressure block 45. The operator rotates the adjusting bolt 44 to move the pressure block 45, thereby adjusting the gap between the pressure block 45 and the guide block 41 to accommodate magnesium ingots 3 of varying widths. A self-locking wire thread insert can be installed in the threaded hole in the support block 42 where the adjusting bolt 44 is connected, to reduce the possibility of the adjusting bolt 44 rotating due to vibration.

[0046] Reference Figure 7 A stopper 55 is fixedly connected to the upper surface of the binder ring 5, capable of abutting the outer side surface of the magnesium ingot 3. The stopper 55 is arranged at one end of the binder 52 along the circumference of the binder ring 5. During the process of the unlocking ring 13 disengaging from the stopper ring 12 and the transition of the stopper rod 53 from the unlocking ring 13 to the stopper ring 12, the magnesium ingot 3 rotates and tilts with the binder ring 5, and the stopper 55 supports the magnesium ingot 3, improving the reliability of the magnesium ingot 3 not moving relative to the stopper 55 during this period.

[0047] Reference Figure 7 A plurality of support rollers 46 are rotatably connected to the opposing inner sides of the binder block 45 and the guide block 41. The support rollers 46 are arranged in an array along the axial direction of the binder block 45 and the guide block 41, and each support roller 46 is arranged perpendicular to the support shaft 11. When the binder ring 5 drives the magnesium ingot 3 toward the cutting blade 2 for feeding via the binder 52, the magnesium ingot 3 abuts against the support rollers 46, converting the sliding friction between the binder block 45 and the magnesium ingot 3, and between the guide block 41 and the magnesium ingot 3, into rotational friction, thereby improving the smoothness of the feeding of the magnesium ingot 3 and reducing the wear of the magnesium ingot 3.

[0048] Reference Figure 7The outer side surface of the limiting rod 53 is slidably sleeved with a material stop block 7, which can support the magnesium ingot 3 after cutting. A reset spring 71 is fixedly connected between the pressure ring 5 and the material stop block 7. The outer side surface of the pressure ring 5 is provided with a receiving groove 57, and the material stop block 7 can move into the receiving groove 57. When the magnesium ingot 3 is cut, the pressure ring 5 moves to abut against the support ring 4. The remaining material of the magnesium ingot 3 is flush with the side of the support ring 4 away from the pressure ring 5 and cannot be cut further. At this time, the material stop block 7 is located in the receiving groove 57, and the reset spring 71 is compressed. When the driving mechanism 6 drives the pressure ring 5 away from the support ring 4 to reset, the reset spring 71 pushes the abutment block 7 out of the accommodating groove 57, and then the pressure piece 52 moves upward to loosen the magnesium ingot 3. The pressure piece 52 drives the abutment block 7 to move upward through the limiting rod 53, so that the abutment block 7 abuts against the lower bottom surface of the cut remaining magnesium ingot 3, preventing the pressure piece 52 from loosening the magnesium ingot 3 and the magnesium ingot 3 from directly detaching from the pressure ring 5 and falling to the bottom of the support shell 1, which is conducive to the operator to replace the magnesium ingot 3 in an orderly manner.

[0049] Reference Figure 1 The upper sidewall of the support housing 1 is hingedly connected to an end cap 16, and a second linear actuator 17 is hingedly connected between the end cap 16 and the support housing 1. When the output shaft of the second linear actuator 17 contracts and drives the end cap 16 to rotate, the support housing 1 is closed, reducing the amount of magnesium chips splashed outside the support housing 1.

[0050] Reference Figure 1 and Figure 3 The drive mechanism 6 includes a rotation source 1 61, a rotating ring 62, and a linear actuator 2 17. The rotation source 1 61 is fixedly connected to the outer side of the support housing 1, and the output shaft of the rotation source 1 61 is fixedly connected to the support shaft 11. The outer side of the pressure ring 5 away from the support ring 4 is rotatably connected to the rotating ring 62. The outer side of the support housing 1 is fixedly connected to the linear actuator 3 63, and the output shaft of the linear actuator 3 63 is fixedly connected to the rotating ring 62. The linear actuator 3 63 pushes the rotating ring 62 toward the support ring 4, and the pressure ring 5 drives the magnesium ingot 3 toward the support ring 4 synchronously with the rotating ring 62.

[0051] The implementation principle of a quick fixing device for a magnesium ingot cutting machine according to an embodiment of the present invention is as follows: during the processing of the magnesium ingot 3, the output shaft of the linear actuator 15 extends to push the unlocking ring 13 into contact with the limiting ring 12. The limiting ring 12 restricts the movement of the pressure plate 522 to the outside of the slide groove 51 through the limiting rod 53 and the sliding block 521, so that the pressure plate 522 presses and fixes the magnesium ingot 3 to the pressure ring 5. The driving mechanism 6 drives the support ring 4 and the pressure ring 5 to rotate around the support shaft 11. The magnesium ingot 3 rotates synchronously with the pressure ring 5 and contacts the cutting blade 2. At the same time, the driving mechanism 6 pushes the pressure ring 5 to move closer to the support ring 4. The pressure ring 5 pushes the magnesium ingot 3 along the axial direction of the support shaft 11 to move closer to the cutting blade 2 for feeding through the pressure plate 522.

[0052] After the magnesium ingot 3 is cut, the drive mechanism 6 drives the binder ring 5 to move away from the support ring 4 to reset. The binder ring 5 pulls the remaining uncut magnesium ingot 3 off the support ring 4 via the binder plate 522. The output shaft of the linear actuator 15 rotates the unlocking ring 13. When the limit rod 53 rotates with the limit ring 12 to an opening, the limit rod 53 is no longer restricted by the limit ring 12. The compressed support spring 54 pushes the binder 52 radially toward the outside of the chute 51, causing the binder 52 to release the magnesium ingot 3. At the same time, the binder 52 drives the limit rod 53 to slide within the waist-shaped groove 432 and simultaneously drives the transmission rod 43 to rotate about the rotating pin 431. The support block 42 rotates synchronously with the limit rod 53 away from the side wall of the magnesium ingot 3, increasing the gap between the guide block 41 and the support block 42. The binder 52 moves synchronously with the limit rod 53 and drives the abutment block 7 upward, causing it to abut the lower surface of the remaining cut magnesium ingot 3. The operator removes the remaining magnesium ingot 3 from the binder ring 5 and places the new magnesium ingot 3 to be cut on the binder ring 5 and the support ring 4. The binder ring 5 continues to drive the limiting rod 53 to rotate, and the limiting rod 53 rotates along the inner side of the unlocking ring 13 to the limiting ring 12. The limiting ring 12 pushes the limiting rod 53 to move inside the limiting ring 12. The binder 52 moves synchronously with the limiting rod 53 to press the magnesium ingot 3 tightly and fix it to the binder ring 5.

[0053] In addition, it should be noted that in the description of the present invention, the terms "install", "connect" and "connect" should be understood in a broad sense.
