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 ingot is a block metal material made of pure magnesium or magnesium alloy. It has the characteristics of light weight, corrosion resistance and high specific strength. It is a new type of industrial metal developed in the 20th century. The main component of magnesium ingot is magnesium (Mg). Magnesium ingot is formed by smelting magnesium ore and casting. It is widely used in the field of modern industrial manufacturing. Before processing magnesium ingot into magnesium powder, it is necessary to chip the magnesium ingot. Magnesium ingot chipping is the process of converting magnesium alloy ingot into debris 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 on a fixing device before cutting. For example, the patent document entitled "Clamping device for metal cutting with flipping structure" with the authorization announcement number CN220278475U, when in use, the controller and the motor are powered by an external power supply. When the metal to be cut needs to be clamped and flipped, the moving plate is pulled so that the two ends of the metal are respectively 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, and 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 is required to turn the knob forward so that the clamping column presses the metal block. When replacing the metal block, the operator is required 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 rotating 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 steps in fixing the metal block.

[0006] To solve the above technical problems, the present invention provides a quick fixing device for a magnesium ingot cutting machine, which includes a support housing; a support shaft is rotatably connected inside the support housing, 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 arranged on the support ring; a limiting ring is fixedly connected to the inner side surface of the support housing close to the pressure ring, an unlocking ring is hinged to the limiting ring, and a linear driver I is hinged to the inner side surface of the support housing through a connecting frame, and the output shaft of the linear driver I is hinged to the unlocking ring; a chute is radially formed in the pressure ring, and a pressure member for fixing the magnesium ingot to the pressure ring is slidably arranged in the chute, a limiting rod located inside the limiting ring is arranged on the pressure member, and a support spring capable of pushing the pressure member to move outwards of the chute is connected to the inner bottom surface of the chute; a driving mechanism is arranged on the support housing, and the driving mechanism is used to drive the support ring and the pressure ring to rotate self, 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 rotate at a low speed. The pressure ring continues to drive the limiting rod to rotate, and the limiting rod rotates along the inner side surface of the unlocking ring to the limiting ring, and the limiting ring pushes the limiting rod to move into the inside of the limiting ring, and the pressure member moves synchronously with the limiting rod to press and fix the magnesium ingot to the pressure ring. The cooperation of the unlocking ring and the support spring is used to realize the automatic release of the pressure member from the magnesium ingot, and when the pressure ring rotates one week around the support shaft, the pressure member is released one by one and the magnesium ingot is tightened again to realize the blanking of the remaining magnesium ingot for cutting and the feeding of the unprocessed magnesium ingot. This process simplifies the operation of the operator's feeding, realizes the function of quickly fixing the magnesium ingot of the magnesium ingot cutting machine, and is beneficial to the efficient cutting and processing of the magnesium ingot.

[0008] Optionally, the pressure member includes a sliding block and a pressure plate which are hinged to each other, the pressure plate is L-shaped and is used to press and fix the magnesium ingot to the pressure ring, the sliding block is sleeved outside the limiting rod in a sliding connection manner, a tension spring is connected between the pressure plate and the pressure ring, and a guide roller is rotatably connected in the chute, and the guide roller is arranged between the inner side surface of the chute and the pressure plate.

[0009] By adopting the above technical solution, when the limiting rod rotates to the notch of the limiting ring, the support spring pushes the sliding block to move outwards of the chute, the pressure plate moves out of the chute synchronously with the sliding block, the guide roller abuts against 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 pressure part protruding from the upper end of the L-shaped pressure plate rotates away from the magnesium ingot, so as to facilitate the operator to 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 with a transmission rod, the transmission rod is hinged to the support ring through a rotating pin I, a waist-shaped groove is formed in the transmission rod, and the limiting rod is slidably arranged in the waist-shaped groove.

[0011] By adopting the above technical solution, when the pressing member moves outward to the outside of the sliding groove to release the magnesium ingot, the pressing member drives the limiting rod to move radially outward along the support ring. While the limiting rod slides in the kidney-shaped groove, it drives the transmission rod to rotate around the first rotating pin. The guiding block rotates synchronously with the limiting rod away from the side wall of the magnesium ingot, increasing the gap between the guiding block and the supporting block, so as to facilitate the operator to remove and install the magnesium ingot.

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

[0013] Optionally, a limiting block capable of abutting against the outer side surface of the magnesium ingot is fixedly connected to the upper surface of the pressing ring, and the limiting block is arranged at one end of the pressing member along the circumferential direction of the pressing ring.

[0014] Optionally, a supporting roller is rotatably connected to the relative inner side surfaces of the pressing block and the guiding block, and the supporting roller is arranged perpendicular to the supporting shaft.

[0015] By adopting the above technical solution, the magnesium ingot abuts against the supporting roller, converting the sliding friction between the pressing block and the magnesium ingot and between the guiding block and the magnesium ingot into rotational friction, improving the smoothness of the magnesium ingot feeding and reducing the wear of the magnesium ingot.

[0016] Optionally, a material abutting block is slidably sleeved on the outer side surface of the limiting rod, the material abutting block can support the magnesium ingot after cutting, and a return spring is fixedly connected between the pressing ring and the material abutting block.

[0017] By adopting the above technical solution, the material abutting block abuts against the lower bottom surface of the remaining cut magnesium ingot, preventing the magnesium ingot from directly falling off the pressing ring to the bottom of the supporting housing after the pressing member releases the magnesium ingot, which is beneficial for the operator to replace the magnesium ingot in an orderly manner.

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

[0019] Optionally, an end cover is hinged to the upper end side wall of the supporting housing, and a second linear driver is hinged between the end cover and the supporting housing.

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

[0021] In summary, compared with the prior art, the present invention includes at least one of the following beneficial technical effects: 1. The cooperation between the unlocking ring and the supporting spring is used to realize the automatic loosening of the blank holder for the magnesium ingot, and when the blank holder rotates one week around the supporting shaft, the blank holder loosens multiple magnesium ingots one by one and tightens the magnesium ingots again, so as to realize the blanking of the remaining magnesium ingots after cutting and the loading of the unprocessed magnesium ingots. This process simplifies the operation of the operator, realizes the function of quickly fixing the magnesium ingot by the magnesium ingot cutting machine, and is beneficial to the efficient cutting processing of the magnesium ingot.

[0022] 2. When the blank holder moves outward to the outside of the chute to loosen the magnesium ingot, the blank holder drives the limiting rod to move radially outward towards the outside of the supporting ring. While the limiting rod slides in the waist-shaped groove, it drives the transmission rod to rotate around the first rotating pin, and the guiding block rotates synchronously with the limiting rod away from the side wall of the magnesium ingot, increasing the gap between the guiding block and the supporting block, so as to facilitate the operator to remove and install the magnesium ingot.

Detailed implementation manners

[0025] For the purpose, technical solutions and advantages of the embodiments of the present invention to be clearer, the following will combine the Figures 1-9 of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention.

[0026] This embodiment provides a quick fixing device for a magnesium ingot cutting machine. Refer to Figure 1 A quick fixing device for a magnesium ingot cutting machine includes a support housing 1, a support ring 4 for supporting the magnesium ingot 3, a pressure ring 5, and a pressure member 52 for fastening the magnesium ingot 3. The lower bottom surface of the support housing 1 is fixedly connected with a bracket 18. The bracket 18 stands on the horizontal plane. The lower side wall of the support housing 1 is conical, and a discharge hole is provided on the lower bottom surface of the support housing 1.

[0027] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 8 and Figure 9, a support shaft 11 is rotatably connected inside the support housing 1. The support ring 4 and the pressure ring 5 are both sleeved on the support shaft 11. The support ring 4 and the pressure ring 5 are both 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 means of spline fit (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 to drive the pressure ring 5 to rotate). The support ring 4 is provided with guide blocks 41 and support blocks 42. There are multiple guide blocks 41 and support blocks 42, which are arranged in a circumferential array along the support ring 4. The guide blocks 41 and the support blocks 42 are arranged in one-to-one correspondence, and the magnesium ingot 3 is placed between the guide blocks 41 and the support blocks 42. The guide block 41 is detachably connected to the support ring 4 by means of bolt fixation. When the magnesium ingot 3 moves axially along the support shaft 11 for material feeding, the guide blocks 41 and the support blocks 42 are used to guide the movement of the magnesium ingot 3. A limiting ring 12 is fixedly connected to the inner side surface of the support housing 1 close to the pressure ring 5. An opening is provided at the upper end of the limiting ring 12, and an unlocking ring 13 is hinged at the opening of the limiting ring 12. A connecting frame 14 is fixedly connected to the inner side surface of the support housing 1. The connecting frame 14 is hinged with a linear actuator 15, and the output shaft of the linear actuator 15 is hinged with the unlocking ring 13.

[0028] Refer to Figure 1 and Figure 4 , the pressure ring 5 is provided with a plurality of sliding grooves 51. The sliding grooves 51 are arranged in a circumferential array along the pressure ring 5 corresponding to the guide blocks 41, and each sliding groove 51 is opened along the radial direction of the pressure ring 5. A pressing member 52 for pressing and fixing the magnesium ingot 3 to the pressure ring 5 is slidably arranged in each sliding groove 51. A limiting rod 53 located inside the limiting ring 12 is provided on the pressing member 52, and a bushing 531 is rotatably sleeved outside the limiting rod 53. The bushing 531 can replace the limiting rod 53 to abut against the inner side surface of the limiting ring 12, thereby reducing the friction coefficient between the limiting rod 53 and the limiting ring 12. A support spring 54 is connected between the inner bottom surface of the sliding groove 51 and the pressing member 52. The support spring 54 can push the pressing member 52 to move towards the outside of the sliding groove 51. The support housing 1 is provided with a driving mechanism 6. The driving mechanism 6 is used to drive the support ring 4 and the pressure ring 5 to rotate self - rotatably and can push the pressure ring 5 to move closer to the support ring 4. A cutting tool 2 is rotatably connected to the inner side surface of the support housing 1.

[0029] 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 member 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 actuator 15 extends to push the unlocking ring 13 to rotate and abut against the limit ring 12, so that the unlocking ring 13 and the limit ring 12 form a complete circular ring. The limit rod 53 is located inside the limit ring 12 and rotates synchronously with the pressure ring 5. At this time, the limit ring 12 restricts the limit rod 53 from moving radially outward of the limit ring 12, that is, the limit ring 12 restricts the pressure member 52 from moving outward of the chute 51 through the limit rod 53, so that the pressure member 52 presses and fixes the magnesium ingot 3 to the pressure ring 5. At this time, the support spring 54 is in a compressed state. The drive 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 tool 2. At the same time, the drive mechanism 6 pushes the pressure ring 5 to move closer to the support ring 4, and the pressure ring 5 pushes the magnesium ingot 3 to move axially along the support shaft 11 closer to the cutting tool 2 through the pressure member 52 for feeding, so as to realize the cutting of the magnesium ingot 3.

[0030] After the cutting of the magnesium ingot 3 is completed, the drive mechanism 6 drives the pressure ring 5 to move away from the support ring 4 for resetting. The pressure ring 5 pulls the remaining uncut magnesium ingot 3 away from the support ring 4 through the pressure member 52. The output shaft of the linear actuator 15 pulls the unlocking ring 13 to rotate counterclockwise (refer to Figure 3 ), so that the opening at the upper end of the limit ring 12 is opened. The drive mechanism 6 drives the pressure ring 5 to rotate self. When the limit rod 53 rotates with the limit ring 12 to the opening, the limit rod 53 lacks the restriction of the limit ring 12, and the compressed support spring 54 pushes the pressure member 52 to move radially outward of the pressure ring 5 toward the chute 51, so that the pressure member 52 loosens the magnesium ingot 3, and the limit rod 53 moves outward of the limit ring 12 synchronously with the pressure member 52 and abuts against the inner side surface of the unlocking ring 13. The operator removes the remaining magnesium ingot 3 on the pressure ring 5 and places a new magnesium ingot 3 to be cut on the pressure ring 5 and the support ring 4.

[0031] After the replacement of the magnesium ingot 3, the drive mechanism 6 drives the pressure ring 5 to run at a low speed. The pressure ring 5 continues to drive the limit rod 53 to rotate. The limit rod 53 rotates along the inner side surface of the unlocking ring 13 to the limit ring 12, and the limit ring 12 pushes the limit rod 53 to move inward of the limit ring 12. The pressure member 52 moves synchronously with the limit rod 53 to press and fix the magnesium ingot 3 to the pressure ring 5. Among them, by setting the length of the unlocking ring 13, the angle of rotation of the magnesium ingot 3 driven by the pressure ring 5 when the limit rod 53 transitions from the unlocking ring 13 to the limit ring 12 can be determined. During this process, the angle of rotation of the magnesium ingot 3 is controlled to keep the magnesium ingot 3 in frictional self-locking with the pressure ring 5, preventing the magnesium ingot 3 from sliding relative to the pressure ring 5 before being completely fastened by the pressure member 52.

[0032] Thus, the cooperation between the unlocking ring 13 and the supporting spring 54 is utilized to realize the automatic release of the pressing member 52 from the magnesium ingot 3, and when the pressing ring 5 rotates one week around the supporting shaft 11, the pressing member 52 releases and re-fastens the magnesium ingot 3 one by one, so as to realize the blanking of the remaining magnesium ingot 3 after cutting and the loading of the unprocessed magnesium ingot 3. This process simplifies the operation of the operator in feeding materials, realizes the function of quickly fixing the magnesium ingot 3 by the magnesium ingot cutting machine, and is beneficial to the efficient cutting process of the magnesium ingot 3.

[0033] Refer to Figure 1 , the cutting tool 2 is arranged on the side of the supporting ring 4 away from the pressing ring 5, and the cutting tool 2 is rotatably connected to the inner side surface of the supporting housing 1. A second rotating source 8 is fixedly connected to the outer side surface of the supporting housing 1. The output shaft of the second rotating source 8 is fixedly connected with a driving wheel 81. A transmission wheel 82 is rotatably connected to the outer side surface of the supporting housing 1. The transmission wheel 82 is coaxially and fixedly connected with the cutting tool 2. A conveyor belt 83 is sleeved on the outer side surfaces of the driving wheel 81 and the transmission wheel 82. The second rotating source 8 drives the cutting tool 2 to rotate self to cut the magnesium ingot 3 through the driving wheel 81, the conveyor belt 83 and the transmission wheel 82 in sequence.

[0034] Refer to Figure 4 , Figure 8 and Figure 9 , the pressing member 52 includes a sliding block 521 and a pressing plate 522. The upper end of the sliding block 521 is hinged to the lower end of the pressing plate 522 through a second rotating pin 524. The pressing plate 522 is L-shaped and is used to press and fix the magnesium ingot 3 on the pressing ring 5. The sliding block 521 is sleeved outside the limiting rod 53 in a sliding connection manner. A tension spring 523 is connected between the pressing plate 522 and the pressing ring 5. A guiding roller 56 is rotatably connected in the chute 51. The guiding roller 56 is arranged between the inner side surface of the chute 51 and the pressing 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 out of the chute 51. The pressing plate 522 moves out of the chute 51 synchronously with the sliding block 521. The guiding roller 56 abuts against 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 second rotating pin 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 as to facilitate the operator to replace the magnesium ingot 3.

[0035] Refer to Figure 5 and Figure 6, a transmission rod 43 is fixedly connected to the lower bottom surface of the support block 42. The transmission rod 43 is hinged to the support ring 4 through a first rotating pin 431. The transmission rod 43 is provided with an oval slot 432, and a limiting rod 53 is slidably arranged in the oval slot 432. When the pressing member 52 moves out of the chute 51 to release the magnesium ingot 3, the pressing member 52 drives the limiting rod 53 to move radially outward of the support ring 4. While the limiting rod 53 slides in the oval slot 432, it drives the transmission rod 43 to rotate clockwise around the first 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 guiding block 41 and the support block 42, so as to facilitate the operator to remove and install the magnesium ingot 3.

[0036] Refer to Figure 6 , an adjusting bolt 44 is threadedly connected to the support block 42. One end of the adjusting bolt 44 close to the guiding block 41 is threadedly connected with a pressing block 45. The magnesium ingot 3 is located between the guiding block 41 and the pressing block 45. The operator rotates the adjusting bolt 44 to drive the pressing block 45 to move, so as to adjust the gap between the pressing block 45 and the guiding block 41 to adapt to magnesium ingots 3 of different width specifications. A self-locking wire thread insert can be arranged in the threaded hole of the support block 42 connected with the adjusting bolt 44 to reduce the probability of the adjusting bolt 44 rotating due to vibration.

[0037] Refer to Figure 7 , a limiting block 55 capable of abutting against the outer side surface of the magnesium ingot 3 is fixedly connected to the upper surface of the pressing ring 5. The limiting block 55 is arranged at one end of the pressing member 52 along the circumferential direction of the pressing ring 5. During the process that the unlocking ring 13 disengages from the limiting ring 12 and the limiting rod 53 transitions from the unlocking ring 13 to the limiting ring 12, the magnesium ingot 3 rotates and tilts with the pressing ring 5, and the limiting block 55 supports the magnesium ingot 3, improving the reliability that the magnesium ingot 3 does not move relative to the limiting block 55 at this time.

[0038] Refer to Figure 7 , a plurality of support rollers 46 are rotatably connected to the relative inner side surfaces of the pressing block 45 and the guiding block 41. The support rollers 46 are axially arranged in an array along the pressing block 45 and the guiding block 41, and each support roller 46 is perpendicular to the support shaft 11. When the pressing ring 5 drives the magnesium ingot 3 to approach the cutting tool 2 for feeding through the pressing member 52, the magnesium ingot 3 abuts against the support rollers 46, converting the sliding friction between the pressing block 45 and the magnesium ingot 3 and between the guiding block 41 and the magnesium ingot 3 into rotational friction, improving the feeding smoothness of the magnesium ingot 3 and reducing the wear of the magnesium ingot 3.

[0039] Refer to Figure 7, a material pressing block 7 is slidably sleeved on the outer side of the limiting rod 53. The material pressing block 7 can support the cut magnesium ingot 3. A return spring 71 is fixedly connected between the material pressing ring 5 and the material pressing block 7. A receiving groove 57 is formed on the outer side of the material pressing ring 5, and the material pressing block 7 can move into the receiving groove 57. When the magnesium ingot 3 is cut, the material pressing ring 5 moves to abut against the supporting ring 4. The remaining material of the magnesium ingot 3 is flush with the side of the supporting ring 4 away from the material pressing ring 5 and cannot be cut continuously. At this time, the material pressing block 7 is located in the receiving groove 57, and the return spring 71 is compressed. When the driving mechanism 6 drives the material pressing ring 5 to reset away from the supporting ring 4, the return spring 71 pushes the material pressing block 7 out of the receiving groove 57. Then the material pressing member 52 moves upward to release the magnesium ingot 3, and the material pressing member 52 drives the material pressing block 7 to move upward through the limiting rod 53, so that the material pressing block 7 abuts against the lower bottom surface of the remaining cut magnesium ingot 3, preventing the magnesium ingot 3 from directly falling off the material pressing ring 5 to the bottom of the supporting housing 1 after the material pressing member 52 releases the magnesium ingot 3, which is beneficial for the operator to replace the magnesium ingot 3 in an orderly manner.

[0040] Refer to Figure 1 , an end cover 16 is hinged to the upper end side wall of the supporting housing 1, and a linear driver II 17 is hinged between the end cover 16 and the supporting housing 1. When the output shaft of the linear driver II 17 contracts to drive the end cover 16 to rotate, the supporting housing 1 can be closed, reducing the amount of magnesium chips splashed outside the supporting housing 1 during cutting.

[0041] Refer to Figure 1 and Figure 3 , the driving mechanism 6 includes a rotation source I 61, a rotation ring 62 and a linear driver II 17. The rotation source I 61 is fixedly connected to the outer side of the supporting housing 1, and the output shaft of the rotation source I 61 is fixedly connected to the supporting shaft 11. The rotation ring 62 is rotatably connected to the outer side of the material pressing ring 5 away from the supporting ring 4. A linear driver III 63 is fixedly connected to the outer side of the supporting housing 1, and the output shaft of the linear driver III 63 is fixedly connected to the rotation ring 62. The linear driver III 63 pushes the rotation ring 62 to move close to the supporting ring 4, and the material pressing ring 5 drives the magnesium ingot 3 to move close to the supporting ring 4 synchronously with the rotation ring 62.

[0042] 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 driver I 15 extends to push the unlocking ring 13 to abut against the limiting ring 12. The limiting ring 12 restricts the movement of the material pressing plate 522 to the outside of the sliding groove 51 through the limiting rod 53 and the sliding block 521, so that the material pressing plate 522 presses and fixes the magnesium ingot 3 to the material pressing ring 5. The driving mechanism 6 drives the supporting ring 4 and the material pressing ring 5 to rotate around the supporting shaft 11. The magnesium ingot 3 rotates synchronously with the material pressing ring 5 and abuts against the cutting tool 2. At the same time, the driving mechanism 6 pushes the material pressing ring 5 to move close to the supporting ring 4, and the material pressing ring 5 pushes the magnesium ingot 3 to move close to the cutting tool 2 along the axial direction of the supporting shaft 11 through the material pressing plate 522 for feeding.

[0043] After the machining of the magnesium ingot 3 is completed, the driving mechanism 6 drives the pressure ring 5 to move away from the support ring 4 for resetting. The pressure ring 5 pulls the remaining uncut magnesium ingot 3 away from the support ring 4 through the pressure plate 522. The output shaft of the linear driver 15 pulls the unlocking ring 13 to rotate. When the limiting rod 53 rotates with the limiting ring 12 to the opening, the limiting rod 53 lacks the restriction of the limiting ring 12, and the compressed support spring 54 pushes the pressing member 52 to move radially outward of the pressure ring 5 along the chute 51, so that the pressing member 52 is disengaged from the magnesium ingot 3. At the same time, while the pressing member 52 drives the limiting rod 53 to slide in the kidney-shaped groove 432, it drives the transmission rod 43 to rotate around the first 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 guiding block 41 and the support block 42. The pressing member 52 moves synchronously with the limiting rod 53 and drives the abutting block 7 to move upward, so that the abutting block 7 abuts against the lower bottom surface of the remaining cut magnesium ingot 3. The operator removes the remaining magnesium ingot 3 on the pressure ring 5 and places the new magnesium ingot 3 to be machined on the pressure ring 5 and the support ring 4. The pressure ring 5 continues to drive the limiting rod 53 to rotate. The limiting rod 53 rotates along the inner side surface of the unlocking ring 13 to the limiting ring 12, and the limiting ring 12 pushes the limiting rod 53 to move inward of the limiting ring 12. The pressing member 52 moves synchronously with the limiting rod 53 to press and fix the magnesium ingot 3 on the pressure ring 5.
