Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of magnesium ingot processing, and particularly relates to an automatic feeding magnesium ingot cutting equipment. BACKGROUND

[0002] Magnesium alloy is widely used in high-end manufacturing industry due to its excellent characteristics of light weight and high strength. A key link in the industry chain is to cut a large long magnesium ingot into a specific specification blank by an automatic cutting equipment for subsequent processing. The existing automatic cutting equipment usually adopts a guide groove type feeding mechanism to carry and guide the magnesium ingot, a pushing device (such as a hydraulic cylinder) at the rear pushes the magnesium ingot to a cutting station, a pressing mechanism clamps and positions the magnesium ingot, and finally a cutting tool (such as a circular saw blade) performs transverse cutting. The cycle operation mode of "pushing-pressing-cutting" is the mainstream process at present.

[0003] However, in long-term practice, the above general scheme has inherent technical defects that are difficult to avoid when dealing with magnesium, which mainly manifests in that:

[0004] A large amount of fine powder (magnesium powder) with strong dispersibility is generated when the magnesium ingot is cut at high speed. These magnesium powders are extremely easy to scatter and invade between the lower surface of the magnesium ingot to be cut and the supporting surface of the feeding guide groove. Under the action of strong feeding thrust, these hard powders carried like abrasives not only cause serious scratches on the relatively soft surface of the magnesium ingot, affecting the appearance and quality of the product, but also sharply increase the frictional resistance of the feeding system, causing "jamming" phenomenon, and even leading to equipment downtime.

[0005] A large amount of high-temperature plastic cutting chips are also generated during the cutting process, which will fall and accumulate in the feeding guide groove. When the subsequent magnesium ingot advances under the thrust, strong extrusion and rolling of the cutting chips which have not cooled and are soft in texture will occur, and the cutting chips are extremely easy to be compacted and bonded on the surface of the guide groove. Irregular hard accumulations are formed after a long period of accumulation, which seriously destroys the core flatness of the guide groove as a positioning reference surface. When the magnesium ingot is clamped, the posture is inclined, which eventually leads to a series of precision problems such as the cutting section being not perpendicular to the ingot axis and the cutting piece being irregular in shape, greatly reducing the product qualification rate. SUMMARY

[0006] In view of the above situation, the application provides an automatic feeding magnesium ingot cutting equipment, which realizes the conveying of the magnesium ingot in a "clamping-advancing-cutting" step-by-step mode by setting a set of feeding and clamping systems and fixed clamping systems which can act in coordination. Before the clamping part contacts the surface of the magnesium ingot, high-pressure gas will instantaneously blow and clean the pre-clamping area, so as to completely avoid the contact surface scratching and feeding jamming phenomenon, and ensure the long-term cleanliness and flatness of the contact part.

[0007] The technical scheme adopted by the present application is as follows: the present application provides an automatic feeding magnesium ingot cutting equipment, which comprises two oppositely arranged mounting vertical plates, a telescopic cutting tool arranged at the downstream end of the mounting vertical plate, and a magnesium ingot passing through the mounting vertical plate, further comprises a plurality of alternating pressing feeding mechanisms, a plurality of alternating pressing fixing mechanisms, a driving assembly and a blowing assembly.

[0010] Further, the driving assembly is drivingly connected with the alternating pressing feeding mechanism and the alternating pressing fixing mechanism on both sides of the magnesium ingot up and down, for driving the first clamping plate and the second clamping plate to alternately clamp and release the magnesium ingot.

[0011] Further, the blowing assembly is arranged on the alternating pressing feeding mechanism and the alternating pressing fixing mechanism, for blowing the contact area before the first clamping plate and the second clamping plate clamp the magnesium ingot.

[0012] Further, the alternating pressing feeding mechanism further comprises a roller, a groove seat fixed on the mounting vertical plate, a triangular sliding groove opened on the surface of the groove seat, and a horizontal sliding rail fixed on the groove seat and close to one side of the magnesium ingot, a rotating shaft is vertically arranged in the center of the groove seat, one end of the rotating shaft is fixedly connected with a swing rod, a sliding channel is opened on the swing rod, the roller passes through the sliding channel and is vertically slidingly matched in the triangular sliding groove, a sliding block is slidingly engaged on the horizontal sliding rail, a first lifting rod is vertically slidingly arranged through the sliding block, one end of the first lifting rod away from the magnesium ingot is rotatably connected with the roller, the first clamping plate is horizontally arranged at one end of the first lifting rod close to the magnesium ingot, and the horizontal edge of the triangular sliding groove close to the magnesium ingot is parallel to the length direction of the magnesium ingot.

[0013] Further, the alternating pressing fixing mechanism further comprises a second lifting rod and an L-shaped rod fixed on the mounting vertical plate, a cylindrical cam is rotatably arranged between the L-shaped rods, a horizontal groove and symmetrically arranged inclined grooves communicated with both ends of the horizontal groove are opened on the outer circumferential wall of the cylindrical cam, the horizontal groove is closer to the magnesium ingot than the inclined grooves, the second lifting rod vertically passes through the L-shaped rods, a roller is arranged on the second lifting rod, the roller is slidingly matched in the horizontal groove and the inclined grooves, and the second clamping plate is horizontally arranged at one end of the second lifting rod close to the magnesium ingot.

[0014] Further, the driving assembly comprises a motor arranged on the mounting vertical plate, a second sprocket coaxially arranged on the output end of the motor, and a first sprocket arranged on the rotating shaft and the L-shaped rod.

[0015] Further, a vertical bevel gear is coaxially arranged on one side of the first sprocket on the L-shaped rod, and a horizontal bevel gear is coaxially arranged on the cylindrical cam.

[0016] Further, the blowing assembly comprises a first air inlet hose, a second air inlet hose, a first air inlet hole, a second air inlet hole and an air outlet hole, the first air inlet hose is connected to the sliding block, the second air inlet hose is connected to the L-shaped rod, the first air inlet hole and the second air inlet hole are arranged on the first lifting rod and the second lifting rod respectively, and the air outlet holes are arranged on the surfaces of the first clamping plate and the second clamping plate.

[0017] Further, the upstream of the mounting vertical plate is provided with a roller conveyor, the roller conveyor comprises a plurality of rollers connected and synchronously driven, and two groups of limiting rods are arranged in a circumferential array in the middle of the rollers.

[0018] Further, in the advancing path of the magnesium ingot, the most upstream of the path is the alternate pressing and feeding mechanism, and the most downstream of the path is the alternate pressing and fixing mechanism; one side of the corresponding second clamping plate at the highest position in the alternate pressing and fixing mechanism at the most downstream and below the magnesium ingot is provided with a falling rod; and the falling rod is vertically fixed on the mounting vertical plate.

[0019] Further, a plurality of guide wheels are arranged on the inner walls of the two mounting vertical plates, and the guide wheels are used for limiting the magnesium ingot on the horizontal two sides.

[0020] Further, when the roller shaft retreats and just enters the horizontal edge of the triangular sliding groove, the roller synchronously leaves the horizontal groove and enters the inclined groove; when the roller shaft advances along the horizontal edge of the triangular sliding groove to the end and is about to leave, the roller synchronously leaves the inclined groove and enters the horizontal groove, and the telescopic cutter can realize one-time cutting within the time period from when the roller just leaves the horizontal groove.

[0021] The beneficial effects achieved by the above structure are as follows:

[0022] (1) The present application adopts a unique "clamping-advancing-cutting" working mode, sets multiple alternating pressing feeding mechanisms and alternating pressing fixing mechanisms, uses the first clamping plate and the second clamping plate to segmentally and alternately clamp and transport magnesium ingots, replaces the continuous sliding support of the traditional guide rail groove on the bottom surface of the magnesium ingot, and greatly reduces the relative sliding and contact area between the magnesium ingot and the bearing part through the intermittent contact of a small area, thereby significantly reducing the risk of scratches on the surface of the magnesium ingot caused by the magnesium powder, and ensuring the appearance quality of the product.

[0023] (2) The present application creatively sets a blowing assembly, which can spray high-pressure gas to the pre-clamping area and the clamping plate working surface before the first clamping plate and the second clamping plate contact and clamp the surface of the magnesium ingot, and the instantaneous blowing process can effectively remove the magnesium powder and fine chips attached to the surface of the magnesium ingot and the surface of the clamping plate, completely avoids the scratches on the magnesium ingot caused by these hard particles under the action of clamping force, eliminates the accumulation, compaction and formation of irregular hard accumulations of chips on the surface of the clamping part, ensures the long-term cleanliness and flatness of the first clamping plate and the second clamping plate as the clamping and positioning reference surface, and avoids the attitude tilt of the magnesium ingot when clamped due to the uneven reference surface.

[0024] (3) The alternating pressing feeding mechanism of the present application can drive the first clamping plate to drive the magnesium ingot to realize accurate and small-step stable advancement through the precise cooperation of the internal rolling shaft in the triangular sliding groove, and after advancing a small fixed distance each time, the second clamping plate of the alternating pressing fixing mechanism can be reliably fixed, and then the telescopic cutting tool is used for cutting. This precise step control and stable cutting front positioning ensure the consistency and cutting accuracy of the cutting length, and greatly improve the product qualification rate.

[0025] (4) The present application also optimizes the design for the processing of the last section of the magnesium ingot. A drop-off rod is arranged on the side of the second clamping plate in the alternating pressing fixing mechanism located at the most downstream and below the magnesium ingot. When only the last section of the magnesium ingot remains and the upstream cannot be clamped by the alternating pressing feeding mechanism, the drop-off rod can assist the last section of the magnesium ingot to tilt and smoothly drop off to the collection area when the second clamping plate downstream is loosened, effectively avoiding the stagnation or jamming of the last section of the material in the equipment.

[0026] (5) Through the initial introduction of the roller conveyor, the automatic collaborative work of the alternating pressing feeding mechanism and the alternating pressing fixing mechanism, the efficient blowing and cleaning, and the reliable last section magnesium ingot processing mechanism, the present application can realize that the subsequent magnesium ingot to be cut continuously enters the processing area after the previous magnesium ingot, and the entire cutting process does not need to be frequently stopped for material replacement or cleaning, realizing true continuous automatic operation and significantly improving the production efficiency.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0040] In the description of the application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings based on the orientation or positional relationship shown in the drawings, and are only intended to facilitate the description of the application and simplify the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the application.

[0041] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 The application proposes an automatic feeding magnesium ingot cutting device, which comprises two oppositely arranged mounting vertical plates 1, a channel for the magnesium ingot 3 to pass through is formed between the mounting vertical plates 1, a retractable cutting tool 4 is arranged at the downstream end of the mounting vertical plate 1, which is used for cutting the magnesium ingot 3, and the key components of the device further comprise a plurality of alternating pressing feeding mechanisms 5, a plurality of alternating pressing fixing mechanisms 6, a driving assembly 7 and a blowing assembly 8.

[0042] The mounting vertical plates 1 are vertically arranged opposite to each other, and a plurality of guide wheels 9 can be arranged on the inner walls of the mounting vertical plates 1. These guide wheels 9 are used to limit the magnesium ingot 3 passing between the mounting vertical plates 1 on the horizontal two sides, so as to ensure the lateral stability of the magnesium ingot 3 in the conveying process. At the upstream of the mounting vertical plate 1, a roller conveyor 2 is arranged, which comprises a plurality of rollers 21. The rollers 21 are synchronously driven through a linkage (such as a chain drive or a gear). A plurality of limiting rods 22 in a circumferential array are arranged at the middle part of each roller 21. Such a design enables the long strip-shaped magnesium ingot 3 to be effectively constrained in a predetermined track when conveying on the roller conveyor 2, and can only be conveyed strictly along the track, thereby laying a foundation for subsequent accurate clamping and feeding.

[0043] The core of the present application is the cooperation of the alternate pressing feeding mechanism 5 and the alternate pressing fixing mechanism 6, which are staggered on the installation vertical plate 1 through the bracket 12 on one side along the advancing direction of the magnesium ingot 3, and in order to stably and balancedly clamp and transport the magnesium ingot 3, the mechanisms are symmetrically arranged along the up and down of the magnesium ingot 3, that is, the upper set of staggered alternate pressing feeding mechanism 5 and alternate pressing fixing mechanism 6 are directly symmetrically arranged to the lower along the center horizontal plane of the magnesium ingot 3, in the advancing path of the magnesium ingot 3, the mechanism located at the most upstream of the path is arranged as the alternate pressing feeding mechanism 5, and the mechanism located at the most downstream of the path (that is, close to the position of the retractable cutting tool 4) is arranged as the alternate pressing fixing mechanism 6, which is beneficial to realize the stable cycle of “clamping-advancing-cutting”.

[0044] Each of the alternate pressing feeding mechanisms 5 is used for clamping and horizontally conveying the magnesium ingot 3, and the specific structure thereof comprises a groove base 51 fixed on the installation vertical plate 1, a specific triangular slide groove 52 is arranged on the surface of the groove base 51, the triangular slide groove 52 is parallel to the length direction (i.e. the feeding direction) of the magnesium ingot 3 near one horizontal side of the magnesium ingot 3, a rotating shaft 54 is vertically arranged in the center of the groove base 51, one end of the rotating shaft 54 is fixedly connected with a swing rod 541, the swing rod 541 swings close to the surface of the groove base 51, a slide groove 542 is arranged on the swing rod 541, a roller 55 passes through the slide groove 542 on the swing rod 541, and the roller 55 can be vertically slidably matched in the triangular slide groove 52, a horizontal slide rail 53 is fixedly arranged on one side of the groove base 51 close to the magnesium ingot 3, a sliding block 56 is clamped and slidably arranged on the horizontal slide rail 53, a first lifting rod 57 is vertically (i.e. perpendicular to the feeding direction of the magnesium ingot 3) slidably arranged on the sliding block 56, one end of the first lifting rod 57 away from the magnesium ingot 3 is rotationally connected with the roller 55, and a first clamping plate 58 is horizontally arranged at one end of the first lifting rod 57 close to the magnesium ingot 3, when the rotating shaft 54 is driven to rotate by the driving assembly 7, the swing rod 541 swings, the roller 55 is driven to move in the triangular slide groove 52 through the slide groove 542, when the roller 55 moves along the horizontal side (i.e. the side close to the magnesium ingot 3) of the triangular slide groove 52, the first lifting rod 57 is driven to horizontally move under the limitation of the sliding block 56 on the horizontal slide rail 53, so that the horizontal movement of the first clamping plate 58 is realized, meanwhile, when the roller 55 moves in a specific position (for example, the oblique side) in the triangular slide groove 52, the first clamping plate 58 is driven to move up and down relative to the magnesium ingot 3 through the connection relationship of the first lifting rod 57, so that the magnesium ingot 3 is clamped or released, specifically, when the roller 55 moves to the horizontal side of the triangular slide groove 52 close to the magnesium ingot 3, the first clamping plate 58 is lowered (or raised, depending on the position in the upper and lower symmetrical arrangement) by the first lifting rod 57 to clamp the magnesium ingot 3, then the first clamping plate 58 and the magnesium ingot 3 are driven to move forward together by the movement of the roller 55 along the horizontal side, when the roller 55 leaves the horizontal side and enters the oblique side of the triangular slide groove 52, the first clamping plate 58 is raised (or lowered) to release the magnesium ingot 3 and retreat.

[0045] Each of the alternate pressing and fixing mechanisms 6 is used to clamp and fix the magnesium ingot 3 during the cutting process, and the specific structure thereof comprises: a U-shaped rod 61 fixed on the mounting vertical plate 1, a cylindrical cam 62 rotatably arranged between the U-shaped rods 61, a specific cam groove being formed on the outer circumferential wall of the cylindrical cam 62, the specific cam groove comprising a horizontal groove 64 and two symmetrical inclined grooves 63 communicating with both ends of the horizontal groove 64, the horizontal groove 64 being closer to the magnesium ingot 3 than the inclined grooves 63, a second lifting rod 65 vertically penetrating through the U-shaped rods 61, a roller 66 being arranged on the second lifting rod 65 and slidingly fitted in the horizontal groove 64 and the inclined grooves 63 of the cylindrical cam 62, and a second clamping plate 67 being horizontally arranged at one end of the second lifting rod 65 close to the magnesium ingot 3. When the driving assembly 7 drives the cylindrical cam 62 to rotate, the roller 66 slides in the horizontal groove 64 and the inclined grooves 63, thereby driving the second lifting rod 65 to produce lifting movement. When the roller 66 enters the horizontal groove 64 close to the magnesium ingot 3, the second lifting rod 65 causes the second clamping plate 67 to lower (or rise) to clamp the magnesium ingot 3. When the roller 66 moves on the symmetrical inclined grooves 63, the second clamping plate 67 always keeps separated from the magnesium ingot 3.

[0046] The driving assembly 7 is used to drive the first clamping plate 58 of the alternate pressing and feeding mechanism 5 and the second clamping plate 67 of the alternate pressing and fixing mechanism 6 to realize the actions of alternate clamping, loosening and feeding the magnesium ingot 3. The driving assembly 7 comprises a motor 11 (usually one above and one below and rotating synchronously) arranged on the mounting vertical plate 1, a second sprocket 75 coaxially arranged on the output end of the motor 11, a first sprocket 71 arranged on the rotating shaft 54 of the alternate pressing and feeding mechanism 5 and the U-shaped rod 61 of the alternate pressing and fixing mechanism 6, and the second sprocket 75 being in transmission connection with all the first sprockets 71 in the corresponding area through a chain 74, thereby realizing synchronous driving. Since the rotating axis of the rotating shaft 54 of the alternate pressing and feeding mechanism 5 (usually perpendicular to the mounting vertical plate 1) and the rotating axis of the cylindrical cam 62 of the alternate pressing and fixing mechanism 6 (usually parallel to the mounting vertical plate 1 and perpendicular to the feeding direction of the magnesium ingot 3) are perpendicular to each other, it is necessary to convert the motion direction. Specifically, a vertical bevel gear 72 is fixed coaxially on one side of the first sprocket 71 on the U-shaped rod 61, and a horizontal bevel gear 73 is fixed coaxially on the cylindrical cam 62, the vertical bevel gear 72 and the horizontal bevel gear 73 are in meshing with each other, thereby converting the rotation transmitted by the chain 74 into the rotation of the cylindrical cam 62.

[0047] By reasonably designing the shape, size and position of the triangular chute 52, the angle, size and position of the horizontal groove 64 and the inclined groove 63 on the cylindrical cam 62, and cooperating with the synchronous driving of the driving assembly 7, the following precise cooperative actions can be realized: when the roller 55 of the alternate pressing feeding mechanism 5 is retracted and just enters the horizontal edge of the triangular chute 52 (i.e., the first clamping plate 58 just clamps the magnesium ingot 3 to prepare for feeding), the roller 66 of the alternate pressing fixing mechanism 6 is synchronized to leave the horizontal groove 64 and enter the inclined groove 63 (i.e., the second clamping plate 67 just releases the magnesium ingot 3), then the roller 55 advances along the horizontal edge of the triangular chute 52 to drive the first clamping plate 58 and the magnesium ingot 3 to advance by a predetermined step, when the roller 55 advances to the end of the horizontal edge of the triangular chute 52 and is about to leave the horizontal edge (i.e., the first clamping plate 58 is about to release the magnesium ingot 3), the roller 66 of the alternate pressing fixing mechanism 6 is synchronized to move from the far state to the close state in the symmetrical inclined groove 63 and accurately enter the horizontal groove 64 (i.e., the second clamping plate 67 just clamps and fixes the magnesium ingot 3), during the time period from the moment when the second clamping plate 67 clamps the magnesium ingot 3 to the moment when the roller 66 is about to leave the horizontal groove 64 (i.e., the second clamping plate 67 is about to release the magnesium ingot 3), the magnesium ingot 3 is firmly fixed, and the telescopic cutter 4 performs a cutting action to cut off the magnesium ingot 3 extending out of the front end.

[0048] In order to solve the problem of magnesium powder and cutting chip pollution, the present application is provided with a blowing assembly 8, which is arranged on the alternate pressing feeding mechanism 5 and the alternate pressing fixing mechanism 6, and is used to blow and clean the surface area of the magnesium ingot 3 and the working surface of the corresponding clamping plate before the first clamping plate 58 and the second clamping plate 67 clamp the magnesium ingot 3.

[0049] The blowing assembly 8 includes a first air inlet hose 81, a second air inlet hose 82, a first air inlet hole 84 opened on the first lifting rod 57, a second air inlet hole 83 opened on the second lifting rod 65, and a plurality of air outlet holes 85 densely opened on the surface of the first clamping plate 58 and the second clamping plate 67 in a hollow structure, the first air inlet hose 81 is connected through the sliding block 56, the corresponding part of the first lifting rod 57 is hollow, and the first air inlet hole 84 is opened on the surface of the rod body at a specific position, when the first clamping plate 58 is about to clamp the magnesium ingot 3, the first air inlet hose 81 is connected through the first air inlet hole 84 on the first lifting rod 57 by passing through the sliding block 56, high-pressure gas enters the hollow first lifting rod 57, and then enters the hollow first clamping plate 58, and is sprayed out at high speed through the air outlet holes 85 on the surface to blow and clean the pre-clamping area, the first air inlet hose 81 has a certain flexibility and can adapt to the small range of horizontal movement of the sliding block 56.

[0050] Similarly, the second air inlet hose 82 is connected through the U-shaped rod 61, and the corresponding part of the second lifting rod 65 is also a hollow structure, and a second air inlet hole 83 is formed in a specific position on the surface of the rod body. When the second clamping plate 67 is about to clamp the magnesium ingot 3, the second air inlet hose 82 can pass through the U-shaped rod 61 and be aligned and communicated with the second air inlet hole 83 on the second lifting rod 65. The high-pressure gas enters the hollow second lifting rod 65 and then enters the hollow second clamping plate 67, and is sprayed out through the air outlet hole 85 on the surface of the second clamping plate 67, thereby completing the blowing. This instantaneous blowing mechanism can effectively blow away the magnesium powder and cutting chips on the surface of the magnesium ingot 3 and the corresponding clamping plate working surface, thereby ensuring the cleanliness of the clamping contact surface.

[0051] In order to process the magnesium ingot 3 cut to the last section, the corresponding second clamping plate 67 in the alternate pressing and fixing mechanism 6 located at the most downstream and below the magnesium ingot 3 is provided with a drop rod 13 on one side (usually the rear side in the feeding direction) when it is in the highest clamping position. The drop rod 13 is vertically fixed to the mounting vertical plate 1. When the magnesium ingot 3 is left with the last section, its length is not enough to be clamped again by the upstream returned alternate pressing and feeding mechanism 5. After the magnesium ingot 3 of the last section is clamped by the second clamping plate 67 at the most downstream and cutting is completed, the second clamping plate 67 is released according to the program. At this time, since there is no clamping force upstream of the second clamping plate 67, the magnesium ingot 3 of the last section will move downward together with the second clamping plate 67 below under the action of gravity. During the descending process, one end of the magnesium ingot 3 of the last section will collide with the fixed drop rod 13. The blocking action of the drop rod 13 will make the magnesium ingot 3 of the last section tilt, so as to smoothly slide off the second clamping plate 67 and drop into the pre-set collection position. In this way, the effective processing of the last section of the material can be ensured, and the obstacle for the subsequent new magnesium ingot 3 to be cut is cleared, thereby realizing continuous cutting.

[0052] In combination with the above structure, the complete working process of the present application is as follows:

[0053] (1) The magnesium ingot 3 is first conveyed by the roller conveyor 2, and its front end enters between the mounting vertical plates 1 under the guidance of the limiting rods 22 and reaches between a pair of (one above and one below) alternate pressing and feeding mechanisms 5 at the most upstream;

[0054] (2) The driving assembly 7 is started, and the motor 11 drives all the first sprockets 71 to rotate synchronously through the second sprocket 75 and the chain 74;

[0055] (3) For the alternate pressing and feeding mechanism 5, the rotation of the rotating shaft 54 drives the swing rod 541 to swing, and the roller shaft 55 moves in the triangular sliding groove 52. When the roller shaft 55 is returned and just enters the horizontal edge of the triangular sliding groove 52, the first lifting rod 57 drives the first clamping plate 58 (symmetrical above and below) to clamp the magnesium ingot 3. At the moment before, the first air inlet hose 81 of the blowing assembly 8 is communicated with the first air inlet hole 84, and the high-pressure gas blows the contact area through the air outlet hole 85 on the first clamping plate 58;

[0056] (4) At the same time, the rollers 66 on the cylindrical cam 62 of the alternate pressing and fixing mechanism 6 synchronously leave the horizontal slot 64 and enter the inclined slot 63, so that the second lifting rod 65 drives the second clamping plate 67 (symmetrical up and down) to loosen the magnesium ingot 3;

[0057] (5) Subsequently, the roller 55 moves forward along the horizontal edge of the triangular slide groove 52, and through the sliding block 56 and the first lifting rod 57, the first clamping plate 58 and the magnesium ingot 3 clamped thereby are fed forward by a predetermined step. Since multiple sets of alternate pressing and feeding mechanisms 5 work together, the magnesium ingot 3 can keep the vertical height position unchanged and the horizontal posture stable during the conveying process;

[0058] (6) When the roller 55 is about to leave the horizontal edge of the triangular slide groove 52 (the first clamping plate 58 is about to loosen the magnesium ingot 3), the rollers 66 on the cylindrical cam 62 synchronously move from the inclined slot 63 and enter the horizontal slot 64, so that the second lifting rod 65 drives the second clamping plate 67 to clamp and fix the magnesium ingot 3. At the moment before, the second air inlet hose 82 of the blowing assembly 8 is in communication with the second air inlet hole 83, and the high-pressure gas blows the contact area through the air outlet hole 85 on the second clamping plate 67;

[0059] (7) After the magnesium ingot 3 is firmly fixed by the second clamping plate 67 of the alternate pressing and fixing mechanism 6, the first clamping plate 58 loosens the magnesium ingot 3 and starts to retreat, preparing for the next clamping and feeding cycle. During the time when the magnesium ingot 3 is fixed, the retractable cutter 4 extends and cuts the part of the magnesium ingot 3 that extends out of the front end;
