Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of magnesium alloy rod processing equipment, in particular to a magnesium alloy rod peeling processing device. BACKGROUND

[0002] Magnesium alloy is widely used in vehicle manufacturing due to its high strength, corrosion resistance and other excellent properties. The magnesium alloy is initially processed into a cylindrical rod body, which is large in volume and heavy in weight, and an oxide layer is formed on the surface. The magnesium alloy rod needs to be cut and peeled before entering the subsequent processing flow. The current peeling process is to use a horizontal lathe to peel off the rod with a pin, first mark the center of the magnesium alloy rod on both sides, then fix the tail end of the magnesium alloy rod in the three-pronged claw disc, and the other end of the center is pushed by a pin. The magnesium alloy rod is rotated by a motor, and the tool on the tool holder peels off the magnesium alloy rod. This peeling method needs to exchange the head and tail twice, which is low in efficiency.

[0003] To improve the problem of needing to exchange the head and tail twice, a magnesium alloy rod peeling device is disclosed in Chinese Patent No. CN213701773U, which includes a lathe provided with a chuck. It also includes an auxiliary disc, which includes a disc body, a clamping part, a centering part, and a fixing part. The clamping part is installed and fixed on the back of the disc body and is in a cylindrical shape, which is clamped by the chuck. The centering part is a protrusion installed and fixed on the front of the disc body and is on the same horizontal line as the center of the cross section of the clamping part. The fixing part is a protrusion installed and fixed on the front of the disc body and is consistent in height with the centering part. The magnesium alloy rod is rotated by the auxiliary disc, and the fixing force is increased, so that the peeling of the magnesium alloy rod can be completed in one positioning, reducing the work intensity and effectively improving the work efficiency. For example, Chinese Patent No. CN221363017U discloses a magnesium rod peeling machine, which includes a lathe provided with a feeding and positioning device on one side for positioning and feeding the magnesium rod. The lathe is also provided with a hydraulic device at one end for tightly pressing the magnesium rod to fix it on the lathe. The feeding and positioning device includes a support, and a feeding cylinder is installed below the support. The stroke of the feeding cylinder can be adjusted according to the positioning center position of the lathe. A bracket is installed at the end of the feeding cylinder rod, which is in an L shape and can position the magnesium rod. Under the pushing of the feeding cylinder, the bracket can lift the magnesium rod to the positioning center of the lathe. The magnesium rod is positioned and fed by the feeding and positioning device provided on one side of the lathe, and then fixed by the hydraulic device for processing, which eliminates the step of manually drilling a center hole and does not require manual fixing of the magnesium rod, thereby improving production efficiency, reducing labor intensity of workers, and avoiding safety accidents. However, the above existing technologies still have the following technical problems: Although the magnesium rod peeling machine disclosed in the above patent can complete peeling once the magnesium alloy rod is positioned and can be loaded by the L-shaped supporting plate, the supporting plate needs to be recycled in the actual peeling process, the magnesium alloy rod may not be tightly clamped by the auxiliary disc and the chuck, and the magnesium alloy rod is prone to relative movement with the auxiliary disc due to stress (gravity, pressure during cutting by the cutter) in the processing process, so that the center of the clamping and positioning reference of the magnesium alloy rod deviates, which increases the peeling processing size error and reduces the processing quality. SUMMARY

[0004] The magnesium alloy rod peeling processing device can solve the problem that the clamping and positioning reference of the magnesium alloy rod deviates due to gravity and pressure of the cutter in the processing of the magnesium alloy rod by the prior art processing equipment, thereby increasing the size error after peeling.

[0005] The magnesium alloy rod peeling processing device comprises a horizontal lathe (1), the horizontal lathe (1) is provided with an auxiliary disc (11) and a thimble (12), further comprises at least two support assemblies arranged on the workbench of the horizontal lathe and located on the same straight line, each support assembly is arranged between the auxiliary disc (11) and the thimble (12). The support assembly comprises a support frame (2), an arc-shaped support plate (3) and at least three steel balls (4), the lower end of the support frame (2) is fixedly connected to the workbench of the horizontal lathe (1), the arc-shaped support plate (3) is arc-shaped and has an open structure at the upper part, the middle end of the arc-shaped support plate (3) is connected to the upper end of the corresponding support frame (2), and the steel balls (4) are uniformly distributed on the inner side of the corresponding arc-shaped support plate (3) and are rotatably connected to the corresponding arc-shaped support plate (3).

[0006] Advantages: 1. Overcome the problem of axial deviation in the clamping and processing of the magnesium alloy rod, improve the size processing precision: the existing equipment only relies on two-point clamping of the auxiliary disc and the thimble, which causes the magnesium alloy rod to easily deviate radially due to its own gravity and cutting pressure during processing, thereby reducing the size precision of the magnesium alloy rod after peeling processing, and the device adds at least two support assemblies arranged on the same straight line below the magnesium alloy rod, which can support the magnesium alloy rod during processing, directly offset the deviation trend caused by gravity and cutting force, avoid the deviation of the reference axis of the magnesium alloy rod body during clamping and positioning from the central axis of the auxiliary disc and the thimble used for clamping the magnesium alloy rod, so that the magnesium alloy rod always rotates stably along the fixed axis, thereby ensuring the peeling processing size precision of the magnesium alloy rod and improving the processing quality.

[0007] 2. The use of rotatable steel balls to reduce friction interference and ensure the stability of magnesium alloy rod rotation processing: The rotatable steel balls evenly distributed on the inner side of the arc support plate can support the magnesium alloy rod and form rolling friction with the steel balls, thereby maximizing the reduction of friction resistance of the magnesium alloy rod during processing rotation, improving the stability of the magnesium alloy rod rotation, and preventing the support assembly from interfering with the rotation of the magnesium alloy rod during processing, further ensuring the dimensional stability of the processing process and improving the pass rate.

[0008] Further, the arc-shaped support plate (3) comprises a first support arc plate (31) and two second support arc plates (32), the first support arc plate (31) and the two second support arc plates (32) are located on the same circumference, and one end of the two second support arc plates (32) is respectively slidably connected to the two ends of the first support arc plate (31), the steel balls (4) are evenly distributed on the first support arc plate (31) and the two second support arc plates (32), and the upper end of the support frame (2) is connected to the outer side of the middle end of the corresponding first support arc plate (31).

[0009] Beneficial effects: The beneficial effects of the arc-shaped support plate design are that the first support arc plate and the two slidable second support arc plates can be flexibly adjusted to adapt to magnesium alloy rods of different diameters, improving the versatility of the device; meanwhile, the steel balls are evenly distributed on the three, and after adjustment, they can still closely fit the surface of the magnesium alloy rod body and realize stable support, thereby ensuring the dimensional accuracy of the magnesium alloy rod processing.

[0010] Further, the inner side of the first support arc plate (31) is provided with an arc-shaped sliding groove (311), and the side surface of the first support arc plate (31) is provided with a plurality of insertion holes (312) transversely penetrating the arc-shaped sliding groove (311), each insertion hole (312) is evenly spaced along the arc direction of the first support arc plate (31), the center axis of the arc-shaped sliding groove (311) and the center axis of the circumference formed by each insertion hole (312) are coaxial, and one end of each of the two second support arc plates (32) near the middle of the first support arc plate (31) is provided with a central hole (321) that can communicate with the insertion hole (312); the two side surfaces of the two second support arc plates (32) are also fixed with a central shaft (33), the central shaft (33) is respectively threadedly connected in the two central holes (321), and one end of the central shaft (33) away from the central hole (321) can be inserted into the insertion hole (312).

[0011] Beneficial effect: The second support arc plate is guided to stably slide along the first support arc plate through the arc-shaped sliding groove, ensures that the two are always in the same circumference during adjustment to guarantee the support fit, can realize accurate positioning through the center shaft and the insertion hole, ensures that the splicing position of the second support arc plate after adjustment is stable and reliable, can be flexibly selected according to the diameter of the magnesium alloy rod, realizes accurate adjustment of the span of the arc-shaped support plate, and ensures that uniform and stable support can be obtained during processing of rods with different diameters.

[0012] Further, a plurality of positioning holes (322) are formed on the outer periphery of the center hole (321) of the second support arc plate (32), the positioning holes (322) are distributed in a circle around the corresponding center hole (321) as the center axis, and the radius of the circle formed by each positioning hole (322) is equal to the distance between the two adjacent insertion holes (312); the first support arc plate (31) is further provided with a positioning shaft (34), which is screwed into the positioning hole (322) on the side surface of the second support arc plate (32) after passing through the insertion hole (312).

[0013] Beneficial effect: On the basis of the preliminary positioning of the center shaft, the positioning lock effect is formed by the cooperation of the positioning shaft and the positioning hole, which limits the radial movement and circumferential rotation of the second support arc plate after adjustment, and ensures the stability of the overall structure after splicing of the arc-shaped support plate; and because the distance between the positioning hole and the insertion hole is matched, accurate positioning and locking can be quickly realized after the second support arc plate is adjusted to the position matching the diameter of the magnesium alloy rod, improving the flexibility and reliability of the adjustment. Further, the arc-shaped support plate (3) further comprises an ear plate (35), an ear shaft (36) and an ear rod (37), the ear plates (35) are distributed at both ends of the first support arc plate (31), the ear shaft (36) is rotatably connected between the corresponding ear plates (35), and the ear rod (37) is screwed into the ear shaft (36).

[0014] Beneficial effect: The ear rod can form additional fixing force after abutting against the second support arc plate, enhancing the stability of the second support arc plate, avoiding vibration of the second support arc plate caused by cutting force during processing, and always ensuring stable constraint of the support structure on the magnesium alloy rod, thereby improving the size accuracy of peeling processing.

[0015] Further, a plurality of ear grooves (323) are formed on the outer periphery side of the second support arc plate (32), and the ends of the ear rods (37) abut against the ear grooves (323) respectively.

[0016] Beneficial effects: The end of the ear rod is prone to slipping when it directly abuts against the outer wall of the arc plate, but the ear groove can form a stable limit on the end of the ear rod, enhancing the support stability of the second support arc plate.

[0017] Furthermore, the support frame (2) includes a base (21) fixedly connected to the horizontal lathe (1) at its lower end, a linear drive (22) fixedly connected to the upper end of the base (21), a top seat (23) fixedly connected to the linear drive (22) at its lower end, and multiple limiting plates (24) whose lower ends are all fixedly connected to the base (21). The upper end of the top seat (23) is connected to the corresponding arc-shaped support plate (3).

[0018] Beneficial effects: The height of the arc-shaped support plate can be flexibly adjusted by the linear drive component, thereby adapting to the support requirements of magnesium alloy rods of different diameters and ensuring that the steel balls on the arc-shaped support plate are in close contact with the outer wall of the rod. On the other hand, multiple limiting plates can guide and limit the lifting process of the top seat, preventing deviation when the linear drive component drives the top seat to lift, and ensuring that the arc-shaped support plate is always stably adjusted in the vertical direction.

[0019] Furthermore, the top seat (23) includes an intermediate plate (231) whose lower end is fixedly connected to the linear drive member (22), four upright plates (232) whose lower ends are fixedly connected to the upper end of the intermediate plate (231), two support members (233), and four clamping plates (234) fixedly connected to each of the upright plates (232). The two ends of the two support members (233) are respectively connected between the two upright plates (232), and the bottom middle of the first support arc plate (31) simultaneously abuts against the two support members (233). The four clamping plates (234) are respectively clamped on both sides of the first support arc plate (31).

[0020] Beneficial effects: The support component provides stable support for the first support arc plate, and together with the clamping plate, it forms clamping and limiting from both sides, ensuring that the arc support plate is firmly connected to the top seat and avoiding displacement caused by vibration during processing; thus improving positioning stability.

[0021] Furthermore, both sides of the first supporting arc plate (31) are provided with arc-shaped clamping grooves (313); the top seat (23) also includes four clamping members (235) with one end connected to the upper end of each clamping plate (234), and the other end of each clamping member (235) extends into and slides into the corresponding arc-shaped clamping groove (313).

[0022] Beneficial effects: The sliding fit between the clamping component and the arc-shaped clamping groove allows the arc-shaped clamping groove to guide and constrain the clamping component, which helps to keep the first supporting arc plate in a sliding state during processing. This allows the first supporting arc plate to adaptively slide and adjust its position when the magnesium alloy rod rotates at high speed, preventing stress concentration caused by the direct rigid connection between the first supporting arc plate and the top seat, preventing deformation of the support frame, and improving the service life of the entire support frame. At the same time, since the direct rigid connection between the first supporting arc plate and the top seat is extremely easy to cause rigid compression or scratches on the surface of the steel ball and the rod due to vibration during processing, the first supporting arc plate in this solution can adaptively slide and adjust its position under force to avoid hard impact between the magnesium alloy rod and the surface of the steel ball, avoid indentations or scratches on the surface of the magnesium alloy rod, and ensure the surface quality of the rod after processing.

[0023] Furthermore, multiple rotating seats (5) are fixedly connected to the inner side of the arc-shaped support plate (3), and each of the steel balls (4) is rotatably connected to each of the rotating seats (5).

[0024] Beneficial effects: The rotating seat forms a partition between the supported magnesium alloy rod and the arc-shaped support plate, preventing collisions between them and ensuring that only rolling friction occurs between the steel ball and the magnesium alloy rod. This provides stable support for the magnesium alloy rod while allowing it to rotate smoothly. It also facilitates the individual disassembly and replacement of worn steel balls and the rotating seat, eliminating the need to replace the entire arc-shaped support plate; reducing maintenance costs and improving maintenance convenience.

[0032] Example 1 like Figures 1 to 6 As shown, the magnesium alloy rod peeling processing device includes a horizontal lathe 1, which is equipped with an auxiliary plate 11 and an ejector pin 12. It also includes at least two support assemblies spaced apart on the worktable of the horizontal lathe and aligned in a straight line. Each support assembly is arranged between the auxiliary plate 11 and the ejector pin 12 to provide support for the magnesium alloy rod. Figure 1 As shown, the auxiliary disk 11 and the ejector pin 12 are components of the horizontal lathe 1, used to clamp the magnesium alloy rod from both ends. The structure of the auxiliary disk 11 and the ejector pin 12 is prior art and will not be described in detail here.

[0033] like Figure 2 and Figure 3 As shown, each support assembly includes a support frame 2, an arc-shaped support plate 3, and at least three steel balls 4. The lower end of the support frame 2 is connected to the worktable of the horizontal lathe 1. The arc-shaped support plate 3 is arc-shaped with an open structure at the top. The included angle of the arc-shaped structure formed by the arc-shaped support plate 3 does not exceed 120° to ensure that the magnesium alloy rod can be smoothly placed into the arc-shaped support plate 3. The middle end of the arc-shaped support plate 3 is slidably connected to the upper end of the corresponding support frame 2. Each steel ball 4 is evenly distributed on the inner side of the arc of the corresponding arc-shaped support plate 3 and is rotatably connected to the corresponding arc-shaped support plate 3. The number of steel balls 4 can be three, four, five, or six, etc. By setting at least three steel balls 4, at least three points of support can be formed for the magnesium alloy rod to ensure the stability of the support for the magnesium alloy rod. At the same time, during the installation process, the rotation of the steel balls 4 facilitates the rotation of the magnesium alloy rod and also facilitates the axial adjustment of the position of the magnesium alloy rod. There are no fewer than three support assemblies to ensure that when a section of the magnesium alloy rod is peeled at a certain point in time, and the corresponding steel ball 4 is removed from the support of the magnesium alloy rod, the other support assemblies can still provide at least two effective supports for the magnesium alloy rod, so as to ensure the stability of the magnesium alloy rod during the peeling process.

[0034] like Figures 3 to 5As shown, each arc-shaped support plate 3 includes a first supporting arc plate 31 and two second supporting arc plates 32. The first supporting arc plate 31 and the two second supporting arc plates 32 are located on the same circumference. An arc-shaped groove 311 is formed on the inner side of the first supporting arc plate 31. One end of each of the two second supporting arc plates 32 is slidably connected to the arc-shaped groove 311. Each steel ball 4 is evenly distributed above the first supporting arc plate 31 and the two second supporting arc plates 32. Figure 2 and Figure 3 Multiple rotating seats 5 are fixedly connected to the inner side of the arc-shaped support plate 3, and each steel ball 4 is rotatably connected within each rotating seat 5. In this embodiment, three rotating seats 5 are provided. One rotating seat 5 is fixedly connected to the inner side of the middle end of the first support arc plate 31. The steel ball 4 located on the inner side of the middle end can ensure effective support for the magnesium alloy rod. The other two rotating seats 5 are respectively fixedly connected to the inner side of the other end of the two second support arc plates 32, and the magnesium alloy rod can be laterally limited and clamped by the other two steel balls 4.

[0035] like Figure 4 As shown, the first supporting arc plate 31 has multiple transverse through arc-shaped grooves 311 with insertion holes 312 on its side. Each insertion hole 312 is evenly spaced along the arc direction of the first supporting arc plate 31. The central axis of the arc-shaped grooves 311 and the central axis of the circumference formed by each insertion hole 312 are coaxial. Each of the two second supporting arc plates 32 has a central hole 321 that can communicate with the insertion hole 312 at one end near the middle of the first supporting arc plate 31. A central shaft 33 is also fixed on both sides of the two second supporting arc plates 32. The central shaft 33 is threaded into the two central holes 321 respectively. The end of the central shaft 33 away from the central hole 321 can be inserted into the insertion hole 312. When it is necessary to adjust the size of the arc support plate 3 according to the size of the magnesium alloy rod to be placed, each central shaft 33 can be removed, so that the second support arc plate 32 slides relative to the first support arc plate 31 along the arc groove 311. Then, the central shaft 33 is inserted into the connected insertion hole 312 and the central hole 321, and threaded to the central hole 321 to achieve size adjustment and ensure that the magnesium alloy rod can be accurately placed into the arc support plate 3.

[0036] like Figure 5 As shown, arc-shaped clamping grooves 313 are provided on both sides of the first support arc plate 31, and the arc-shaped clamping grooves 313 are coaxial with the first support arc plate 31.

[0037] like Figure 5As shown, the second support arc plate 32 is provided with multiple positioning holes 322 on the outer periphery of the central hole 321. The positioning holes 322 are circumferentially spaced with the corresponding central hole 321 as the central axis, and the radius of the circumference formed by each positioning hole 322 is equal to the distance between two adjacent insertion holes 312. The first support arc plate 31 is also provided with a positioning shaft 34, which passes through the insertion hole 312 and is threaded into the positioning hole 322 on the side of the second support arc plate 32. The outer periphery of the two second support arc plates 32 near the central hole 321 is set as an arc surface structure, and the arc surface structure is with the corresponding central hole 321 as the central axis to ensure that the second support arc plate 32 rotates smoothly relative to the first support arc plate 31 with the central axis 33 as the central axis. When adjusting the size of the arc-shaped support plate 3 by sliding the second support arc plate 32 relative to the first support arc plate 31, the relative distance between the other ends of the two second support arc plates 32 can be adjusted by rotating the second support arc plate 32 relative to the first support arc plate 31 about the central axis 33. Then, the positioning shaft 34 is inserted into the connected insertion hole 312 and positioning hole 322 and threaded into the positioning hole 322 to maintain the relative distance between the other ends of the two second support arc plates 32, thereby supporting magnesium alloy rods of different diameters.

[0038] like Figure 5 As shown, each arc-shaped support plate 3 also includes four ear plates 35, two trunnions 36, and two ear rods 37. The four ear plates 35 are distributed in pairs at both ends of the first support arc plate 31. The two trunnions 36 are respectively distributed at both ends of the first support arc plate 31, and the two ends of the two trunnions 36 are rotatably connected to the corresponding two ear plates 35. The two ear rods 37 pass through and are threadedly connected to the two trunnions 36. The ends of the two ear rods 37 abut against the outer circumference of the two second support arc plates 32. The outer circumference of the two second support arc plates 32 is provided with multiple ear grooves 323. The ends of the two ear rods 37 abut against the ear grooves 323 of the two second support arc plates 32. The ear grooves 323 limit the abutment of the ear rods 37, ensuring that the ear rods 37 form a stable support for the second support arc plates 32.

[0039] After adjusting the relative distance between the other ends of the two second support arc plates 32 by rotating the second support arc plate 32 relative to the first support arc plate 31 with the central axis 33 as the central axis, the ear rod 37 can be rotated to press against the outer side of the corresponding second support arc plate 32, so that the ear rod 37 can simultaneously support the corresponding second support arc plate 32, thereby improving the support stability of the second support arc plate 32 on the magnesium alloy rod.

[0040] like Figure 2 , Figure 3 as well as Figure 6The support frame 2 includes a base 21 fixedly connected to the lower end of the horizontal lathe 1, a linear drive component 22 fixedly connected to the upper end of the base 21, a top seat 23 fixedly connected to the lower end of the linear drive component 22, and multiple limiting plates 24, each fixedly connected to the lower end of the base 21. The upper end of the top seat 23 is connected to a corresponding arc-shaped support plate 3. The linear drive component 22 can be a ball screw drive mechanism, synchronous belt drive, electric push rod, electric cylinder, cam mechanism, cylinder mechanism, or linear motor driven linear drive mechanism, etc. The drive end of the linear drive component 22 can be connected to the center position of the top seat 23. In this embodiment, the linear drive component 22 is shown as a cylinder. As a technically known method to those skilled in the art, the linear drive component 22 can be communicatively connected to the PLC controller of the horizontal machine tool 1 to control the start and stop of the linear drive component 22. As is known to those skilled in the art, a plurality of stepped grooves for fixing fixtures are provided through the worktable of the horizontal lathe 1. In this embodiment, a slider 211 is fixedly connected to the lower side of the base 21. The slider is adapted to and slidably connected to the stepped groove so as to change the distance between two adjacent support assemblies by sliding, thereby supporting magnesium alloy rods of different lengths. Of course, after sliding, the base 21 can be fixed by tightening the screws threaded to the worktable of the horizontal lathe 1. This fixing method is a conventional method of existing lathes and will not be described in detail here.

[0041] The top seat 23 includes an intermediate plate 231 whose bottom end is fixedly connected to the linear drive component 22, four upright plates 232 whose lower ends are all fixedly connected to the upper ends of the intermediate plate 231, two support members 233, and four clamping plates 234 whose lower ends are respectively fixedly connected to the upper ends of each upright plate 232. The two ends of the two support members 233 are respectively fixedly connected between the two upright plates 232, and the bottom middle of the first support arc plate 31 simultaneously abuts against the two support members 233. The four clamping plates 234 are respectively clamped on both axial sides of the arc-shaped support plate 3. In this embodiment, the support member 233 is preferably a round shaft, and its end is rotatably connected between the corresponding upright plates 232. During the installation of the magnesium alloy rod, the arc-shaped support plate 3 supports the magnesium alloy rod through the steel ball 4. The force on the arc-shaped support plate 3 can cause the support member 233 to rotate adaptively, adjusting the angle of the arc-shaped support plate 3 indirectly supporting the magnesium alloy rod.

[0042] like Figure 6As shown, the top seat 23 also includes four clamping members 235, one end of which is connected to the upper end of each clamping plate 234. The other end of each clamping member 235 extends into and is slidably connected to the corresponding arc-shaped clamping groove 313. By having the other end of each clamping member 235 extend into and be slidably connected to the corresponding arc-shaped clamping groove 313, the arc-shaped support plate 3 is further limited, ensuring that the arc-shaped support plate 3 indirectly provides stable support for the magnesium alloy rod. In this embodiment, the clamping member 235 is preferably a round shaft, and its end is rotatably connected to the corresponding clamping plate 234, so that when the first support arc plate 31 moves and adjusts its position, the clamping member 235 can reduce friction by rotating.

[0043] It should be noted that under the influence of gravity of the magnesium alloy rod and the clamping action of the magnesium alloy rod, the arc-shaped support plate 3 will not rotate arbitrarily relative to the top seat 23 during the peeling process, thus ensuring that the magnesium alloy rod is stably supported.

[0044] The method of using this device is as follows: During processing, the magnesium alloy rods can be installed and removed by hoisting. The specific structure and working method of the horizontal lathe 1 are well known to those skilled in the art, and therefore will not be described in detail here. When placing the magnesium alloy rod, it is placed on each support assembly. Each arc-shaped support plate 3 forms a stable support for the magnesium alloy rod through point contact with the corresponding steel balls 4. Then, the auxiliary plate 11 and the ejector pin 12 are respectively placed on both ends of the magnesium alloy rod. During processing, the clamped magnesium alloy rod rotates and is cut off by the tool mounted on the horizontal lathe 1. At the same time, the corresponding top seat 23 can be driven to move vertically through each linear drive component 22, so that the height of the corresponding arc-shaped support plate 3 is increased. This ensures that after the outer diameter of the magnesium alloy rod is cut and becomes smaller, the steel balls 4 can quickly contact the outer periphery of the magnesium alloy rod to form a continuous and effective support for the magnesium alloy rod. This ensures that the magnesium alloy rod, the auxiliary plate 11 and the ejector pin 12 are on the same straight line, thereby preventing the magnesium alloy rod under force from shifting its axis. This solves the problem that in the existing processing equipment, when clamping and processing magnesium alloy rods, the clamping positioning reference of the magnesium alloy rod is easily shifted due to gravity and the pressure of the tool, resulting in an increase in the dimensional error after peeling.

[0045] Example 2 The difference between this embodiment and Embodiment 1 is that one end of the clamping member 235 is fixedly connected to the corresponding clamping plate 234, and the support member 233 is a plate-shaped structure with an upper side having a bottom arc-shaped curved surface adapted to the first support arc plate 31, and its end is fixedly connected between the corresponding upright plates 232, so as to achieve stable support for the arc-shaped support plate 3 by contacting the bottom arc surface of the first support arc plate 31 through the two arc surfaces.

[0046] The above are merely embodiments of the present invention, and the invention is not limited to the fields covered by these embodiments.
