Description

Technical Field

[0001] The invention relates to the field of fixture equipment, in particular to a fixture for processing magnesium ingots. Background Art

[0002] Magnesium ingots are usually cast. Due to the requirement for smooth demoulding, the cross-section of the magnesium ingot casting mold is usually an isosceles trapezoidal structure, which makes the magnesium ingot also an isosceles trapezoidal structure. Fixed-length cutting is a common process in magnesium ingot processing. In order to ensure the cutting quality, it is necessary to use tooling fixtures to fix multiple magnesium ingots in batches. The stability of the fixation directly affects the vibration control, incision flatness and dimensional accuracy during the cutting process. If the fixation is not firm, the magnesium ingot may be displaced or shaken during cutting, resulting in tilted cutting surface, inconsistent length or burrs, which seriously affects product quality and production efficiency.

[0003] The tooling fixture in the prior art usually includes a base, a lower pressure plate and a side pressure plate. When in use, the magnesium ingots are arranged in an upright and reverse manner and tightly arranged on the base. The side pressure plates apply pressure from one or both sides to squeeze the magnesium ingots close to each other and fix them. Then the lower pressure plate descends and presses on the upper side of the magnesium ingot, thereby limiting the position of the magnesium ingot. This arrangement ensures that the magnesium ingot will not move in the horizontal direction through mechanical clamping, and cooperates with the pushing mechanism to achieve fixed-length cutting of the magnesium ingot.

[0004] However, the existing tooling fixtures still have obvious shortcomings. First, the closely arranged magnesium ingots will lead to poor heat dissipation during cutting, making the magnesium ingots prone to high temperatures during the cutting process, and at the same time causing the generated magnesium chips to easily accumulate, increasing the risk of combustion and explosion. Second, the lower pressure plate and side pressure plates usually require multiple drive structures to be independently controlled, which increases the operation steps and complexity and reduces processing efficiency.

[0005] In addition, the existing design lacks effective limiting of the end of the magnesium ingot and only relies on the fixed-length pushing of the pushing mechanism to control the cutting position. Due to pushing errors or blockage of the movement of the magnesium ingot, the cutting length is often inconsistent, which seriously affects the accuracy and product quality. Summary of the Invention

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: a tooling fixture for processing magnesium ingots, including a base plate, on which a left bracket and a right bracket arranged on the left and right and both having a U-shaped structure are fixedly installed, the left bracket is provided with a clamping mechanism for quickly fixing the magnesium ingot, and the right bracket is provided with a blocking mechanism for limiting and aligning the end of the magnesium ingot.

[0007] The clamping mechanism includes a pressing plate that slides up and down between two vertical sections of the left bracket. The pressing plate is provided with a plurality of clamping components, and the clamping components include two clamping plates for abutting against the front and rear sides of the magnesium ingot.

[0008] When the pressing plate is pressed against the upper side of the magnesium ingot, the clamping assembly automatically drives the clamping plate to adaptively fit and clamp on the front and rear sides of the magnesium ingot.

[0009] The blocking mechanism includes an active plate that slides up and down between the two vertical sections of the right bracket. The active plate is provided with a plurality of blocking plates arranged at equal intervals along the front-to-back direction through a linkage component, and the lower part of the blocking plate is an L-shaped structure.

[0010] The vertical section of the L-shaped structure of the blocking plate moves to the right side of the magnesium ingot. When the magnesium ingot moves until its right end abuts against the vertical section of the L-shaped structure of the blocking plate, the right ends of the several magnesium ingots are aligned.

[0011] A number of limit plates and separation blocks are fixedly installed at equal intervals along the front-to-back direction on the left side of the base plate. The limit plates correspond to the separation blocks one by one, and the separation blocks are located on the left side of the limit plates. The limit plates are arranged obliquely.

[0012] Preferably, the plurality of clamping assemblies are divided into two groups, the number of clamping assemblies in the two groups is equal, each group is composed of a plurality of clamping assemblies arranged at equal intervals along the front-to-back direction, and the left and right groups of clamping assemblies are staggered in the front-to-back direction.

[0013] Preferably, the clamping assembly also includes a sliding block that slides up and down on the pressure plate, and two T-shaped plates that are symmetrically arranged front to back and slide back and forth on the lower side of the pressure plate. The two T-shaped plates are hinged to the clamping plates at the corresponding positions on one side close to each other.

[0014] Preferably, the front and rear sides of the sliding block are hinged with linkage plates, the linkage plates are hinged to the horizontal sections of the T-shaped plates at corresponding positions, the internal threads of the sliding block are connected with screws, and a tension spring is provided between the sliding block and the pressure plate.

[0015] Preferably, a rocker is fixedly mounted on the upper end of the screw, and the rocker located in the same group of clamping components is connected to a synchronous plate for common rotation away from the end of the screw.

[0016] Preferably, a side of the clamping plate close to the corresponding sliding block is provided with a plurality of transversely arranged grooves at equal intervals along the width direction of the clamping plate.

[0017] Preferably, the linkage assembly includes a push plate that is evenly spaced along the front-to-back direction and slides in the vertical direction on the active plate. The lower part of the push plate is an inclined structure. The blocking plate is slidably connected to the inclined surface of the lower part of the push plate. A coil spring is provided between the active plate and the push plate.

[0018] Preferably, a fixing plate is fixedly installed between the two vertical sections of the right bracket, and positioning plates are fixedly installed at equal intervals along the front-to-back direction on the right side of the fixing plate, and the positioning plates correspond to the blocking plates one by one.

[0019] Preferably, the right side of the lower end of the blocking plate is hinged with a push plate through a hinge plate, a torsion spring is provided between the hinge plate and the blocking plate, and a conveying roller is rotatably provided on the base plate corresponding to the position of the push plate.

[0020] The beneficial effects of the present invention are: 1. The present invention adopts a linkage design of the pressure plate and the clamping assembly, so that when the pressure plate presses down to squeeze the upper side of the magnesium ingot, it can automatically drive the clamping plate to shrink inward synchronously to fit and clamp the front and rear sides of the magnesium ingot. This design achieves upper pressing and side clamping synchronously through a single downward pressing action, significantly reducing the number of independent driving structures and greatly simplifying the operating process. At the same time, the independent clamping assembly independently fixes the magnesium ingot blocks to form an effective heat dissipation gap, avoiding high temperature accumulation and magnesium chips accumulation during cutting, and significantly reducing the risk of combustion and explosion.

[0021] 2. The present invention uses a blocking plate in the blocking mechanism to limit the end of the magnesium ingot. The active plate pushes the vertical section of the L-shaped structure of the blocking plate to the right side of the magnesium ingot. When the pushing mechanism pushes the right end of the magnesium ingot against the vertical section of the blocking plate, it forces the right ends of all magnesium ingots to be precisely aligned with the same vertical plane. The physical hard limit mechanism eliminates the pushing positioning error and ensures the high consistency of the cutting length.

[0022] 3. The present invention flexibly controls the horizontal sliding stroke of the T-shaped plate by turning the screw, thereby realizing adaptive clamping of magnesium ingots of different thicknesses. At the same time, the inclined limit plate and the separator block form a guide channel, guiding the magnesium ingot to quickly slide into the work station along a preset path, significantly simplifying the magnesium ingot loading steps and improving cutting efficiency.

[0023] 4. The present invention adopts the inclined sliding cooperation of the blocking plate and the pushing plate, so that when cutting, the blocking plate has a tendency to push the magnesium ingot to the right, so that after the cutting is completed, the blocking plate immediately pushes the magnesium ingot block to move to the right along the conveyor roller to avoid it, actively avoiding the magnesium ingot block from contacting the saw blade, effectively protecting the cutting tool, avoiding the high-temperature block from sticking to the saw blade and causing sparks, and further enhancing safety protection in conjunction with the heat dissipation gap.

[0033] The following embodiments of the present invention are described in detail. The embodiments described below are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, the techniques or conditions described in the literature in the art or in the product specifications shall be followed.

[0034] See Figure 1 、 Figure 4 and Figure 6 A tooling fixture for processing magnesium ingots includes a base plate 1, on which a left bracket 2 and a right bracket 3 arranged on the left and right and both having a U-shaped structure are fixedly installed. The left bracket 2 is provided with a clamping mechanism 4 for quickly fixing the magnesium ingot, and the right bracket 3 is provided with a blocking mechanism 5 for limiting and aligning the end of the magnesium ingot.

[0035] When it is necessary to cut the magnesium ingot to a fixed length, the magnesium ingot is first separated and placed on the base plate 1, and then the magnesium ingot is pushed to the right by the existing pushing mechanism, so that the magnesium ingot is aligned and extended into the corresponding position of the clamping mechanism 4, and the right end of the magnesium ingot is against the blocking mechanism 5, so that by aligning the right end faces of several magnesium ingots, the part of each magnesium ingot located on the right side of the saw blade is of equal length, and then each magnesium ingot is independently and quickly clamped and fixed by the clamping mechanism 4.

[0036] Then, by moving the saw blade forward, the magnesium ingots are cut to a fixed length one by one from back to front. Whenever a magnesium ingot is cut, the blocking mechanism 5 can automatically push the cut block of the magnesium ingot to the right to prevent the magnesium ingot block from contacting the saw blade, effectively protecting the cutting tool and avoiding high-temperature blocks sticking to the saw blade to cause sparks.

[0037] See Figure 1 A plurality of limit plates 43 and partition blocks 431 are fixedly installed at equal intervals along the front-to-back direction on the left side of the base plate 1. The limit plates 43 correspond to the partition blocks 431 one by one, and the partition blocks 431 are located on the left side of the limit plates 43. The limit plates 43 are arranged obliquely.

[0038] It should be noted that the inclination directions of two adjacent limiting plates 43 are opposite, so that the limiting plates 43 can adapt to the front and rear side surfaces of the magnesium ingot placed one upright and the other upside down.

[0039] When the magnesium ingot needs to be cut to a fixed length, the operator places the magnesium ingot on the upper part of the base plate 1, and makes each magnesium ingot located between two adjacent partition blocks 431, and then pushes the magnesium ingot to the right through the existing pushing structure, so that the magnesium ingot moves to between two adjacent limit plates 43, so that the limit plates 43 and the partition blocks 431 jointly guide the magnesium ingot.

[0040] It should be noted that the height of the partition block 431 is relatively low, so that when the operator places the magnesium ingot between two adjacent partition blocks 431, the magnesium ingot is located on the upper part of the partition block 431. By flexibly moving the magnesium ingot back and forth, the magnesium ingot falls between the two adjacent partition blocks 431, thereby facilitating the initial placement of the magnesium ingot. The height of the limit plate 43 is relatively high, so that when the magnesium ingot is inserted between the two adjacent limit plates 43, it cannot move a large distance back and forth, thereby ensuring the guiding accuracy of the magnesium ingot.

[0041] It should be noted that the partition block 431 is mainly used to provide preliminary guidance and limiting effects on the magnesium ingot to prevent the magnesium ingot from moving a large distance in the front and rear directions. This degree of guiding and limiting effect can be achieved without making the magnesium ingot and the partition block 431 completely fit together. Therefore, even if there is a certain deviation between the sizes of multiple magnesium ingots, the millimeter-level dimensional deviation in the existing casting technology will not affect the guiding and limiting effect of the partition block 431. Similarly, the dimensional deviation of the magnesium ingot will not affect the limiting effect of the limiting plate 43 used to limit the magnesium ingot in the front and rear directions.

[0042] See Figure 1 、 Figure 3 、 Figure 6 and Figure 7The blocking mechanism 5 includes an active plate 51 that slides up and down between the two vertical sections of the right bracket 3. A plurality of blocking plates 53 are arranged at equal intervals along the front-to-back direction on the active plate 51 through a linkage assembly 52. ​​The lower part of the blocking plate 53 is an L-shaped structure. The vertical section of the L-shaped structure of the blocking plate 53 moves to the right side of the magnesium ingot. When the magnesium ingot moves to the point where its right end abuts against the vertical section of the L-shaped structure of the blocking plate 53, the right ends of the plurality of magnesium ingots are aligned.

[0043] See Figure 6 and Figure 7 The linkage assembly 52 includes a push plate 521 that is evenly spaced along the front-to-back direction and slides in the vertical direction on the active plate 51. The lower part of the push plate 521 is an inclined structure. The blocking plate 53 is slidably connected to the inclined surface of the lower part of the push plate 521. A coil spring is provided between the active plate 51 and the push plate 521.

[0044] Continue reading Figure 6 and Figure 7 A fixing plate 54 is fixedly installed between the two vertical sections of the right bracket 3, and positioning plates 541 are fixedly installed at equal intervals along the front-to-back direction on the right side of the fixing plate 54, and the positioning plates 541 correspond to the blocking plates 53 one by one.

[0045] It should be noted that in this embodiment, an electric cylinder No. 1 is fixedly installed on the upper side of the horizontal section of the right bracket 3, the telescopic section of the electric cylinder No. 1 is fixedly connected to the active plate 51, and a wedge-shaped groove is provided on the upper part of the blocking plate 53, and the inclined surface of the wedge-shaped groove is slidably connected with the inclined surface of the lower part of the push plate 521.

[0046] In the initial state, electric cylinder No. 1 drives active plate 51 to a position close to the horizontal section of right bracket 3, and the coil spring pushes the pushing plate 521 downward by its own elastic force. The blocking plate 53 slides downward along the inclined surface of the lower part of the pushing plate 521 under the action of its own gravity, so that the right vertical surface of the wedge-shaped groove of the blocking plate 53 abuts against the pushing plate 521, and at the same time, the left part of the upper side surface of the blocking plate 53 abuts against the lower side surface of the fixed plate 54, and the left vertical surface of the wedge-shaped groove of the blocking plate 53 fits against the left side surface of the positioning plate 541 at the corresponding position.

[0047] When the pushing mechanism starts to push the magnesium ingot to the right, the telescopic section of the No. 1 electric cylinder extends to drive the active plate 51 to move downward, and the active plate 51 pushes the pushing plate 521 downward through the coil spring, and the pushing plate 521 drives the blocking plate 53 to move downward synchronously until the vertical section of the L-shaped structure at the bottom of the blocking plate 53 is located to the right of the end of the magnesium ingot, and at this time, the vertical surface on the left side of the wedge-shaped groove of the blocking plate 53 is still in contact with the left side surface of the positioning plate 541 at the corresponding position.

[0048] See Figure 1 、 Figure 3 、 Figure 4 and Figure 5The clamping mechanism 4 includes a pressure plate 41 that slides up and down between the two vertical sections of the left bracket 2. A number of clamping components 42 are provided on the pressure plate 41. The clamping components 42 include two clamping plates 421 for resting on the front and rear side surfaces of the magnesium ingot. When the pressure plate 41 is squeezed on the upper side of the magnesium ingot, the clamping components 42 automatically drive the clamping plates 421 to adaptively fit and clamp on the front and rear side surfaces of the magnesium ingot.

[0049] In the initial state, the clamping plates 421 are in a vertical state due to their own weight, and the two clamping plates 421 in the same clamping assembly 42 are in positions away from each other.

[0050] Subsequently, the pushing mechanism pushes the magnesium ingots to move along the guide of the limit plate 43 to the lower part of the pressure plate 41, so that each magnesium ingot is located between the two clamping plates 421 in a clamping assembly 42 at the corresponding position, and then continues to move the magnesium ingots so that the right end face of the magnesium ingot rests on the vertical section of the L-shaped structure at the lower part of the blocking plate 53. At this time, since the blocking plate 53 is blocked by the positioning plate 541, the right end face of the magnesium ingot cannot push the blocking plate 53 to the right, and then the pushing mechanism pushes the right ends of all magnesium ingots to accurately align with the same vertical plane, and eliminates the pushing positioning error through the physical hard limit mechanism to ensure the high consistency of the cutting length.

[0051] See Figure 1 and Figure 4 In order to ensure that the magnesium ingots arranged in an upright and reversed manner can be clamped, while avoiding the distance between two adjacent magnesium ingots being too large to affect the cutting efficiency, this embodiment adopts the following design: a plurality of clamping components 42 are divided into two groups on the left and right, and the number of the two groups of clamping components 42 is equal. Each group is composed of a plurality of clamping components 42 arranged at equal intervals along the front-to-back direction, and the left and right groups of clamping components 42 are staggered in the front-to-back direction.

[0052] Two groups of staggered clamping assemblies 42 are used to independently clamp the upright and inverted magnesium ingots. While independently clamping the magnesium ingots, space is left for arranging the clamping assemblies 42 to avoid an excessive distance between the two magnesium ingots.

[0053] See Figure 4 and Figure 5 The clamping assembly 42 also includes a sliding block 422 that slides up and down on the pressure plate 41, and two T-shaped plates 423 that are symmetrically arranged front to back and slide back and forth on the lower side of the pressure plate 41. The two T-shaped plates 423 are close to each other and hinged to the clamping plate 421 at the corresponding position.

[0054] Continue reading Figure 4 and Figure 5The front and rear sides of the sliding block 422 are hinged with linkage plates 424, the linkage plates 424 are hinged with the horizontal sections of the T-shaped plates 423 at the corresponding positions, the internal threads of the sliding block 422 are connected with screw rods 425, and a tension spring is provided between the sliding block 422 and the pressure plate 41.

[0055] In the initial state, the tension spring pulls the sliding block 422 downward by its own elastic force, so that the sliding block 422 pushes the two T-shaped plates 423 at the corresponding positions outward through the two linkage plates 424 thereon, and the T-shaped plates 423 drive the clamping plates 421 thereon to move synchronously, so that the two clamping plates 421 located at the same sliding block 422 in the initial state move away from each other.

[0056] It should be noted that since the hinge between the clamping plate 421 and the T-shaped plate 423 is located in the upper middle part of the clamping plate 421, the clamping plate 421 relies on gravity to maintain a vertical state in the absence of external force. In this embodiment, a No. 2 electric cylinder is fixedly installed on the upper side of the horizontal section of the left bracket 2, and the telescopic section of the No. 2 electric cylinder is fixedly connected to the pressure plate 41.

[0057] Before starting to cut the magnesium ingot, the operator rotates the screw 425 in advance to adjust the distance between the lower end face of the screw 425 and the sliding block 422. When the right end face of the magnesium ingot is pressed against the blocking plate 53, the telescopic section of the No. 2 electric cylinder is extended to drive the pressure plate 41 to move downward, so that the pressure plate 41 drives the lower end face of the adjusting screw 425 to press against the upper side of the magnesium ingot through the sliding block 422.

[0058] Then the pressure plate 41 continues to move downward, and the adjusting screw 425 is blocked by the magnesium ingot and remains in position, so that the height position of the sliding block 422 driven by the adjusting screw 425 remains unchanged, thereby causing the pressure plate 41 to move downward relative to the sliding block 422. At the same time, the pressure plate 41 drives the clamping plate 421 to move downward synchronously through the T-shaped plate 423, which makes the two clamping plates 421 at the same sliding block 422 approach each other under the pull of the linkage plate 424.

[0059] When the pressure plate 41 rests against the upper side of the magnesium ingot, the two clamping plates 421 at the same sliding block 422 rest against and clamp the front and rear sides of the magnesium ingot, and the reaction force of the side of the magnesium ingot against the clamping plates 421 pushes the clamping plates 421 to adaptively rotate and fit on the front and rear sides of the magnesium ingot, thereby conveniently completing the horizontal and vertical limitation of the magnesium ingot.

[0060] Continue reading Figure 4 and Figure 5 In order to quickly rotate the screw 425, the following design is made in this embodiment: a rocker 426 is fixedly installed on the upper end of the screw 425, and the rocker 426 located in the same group of clamping components 42 is connected to a synchronous plate 427 away from the end of the screw 425 for common rotation.

[0061] When the operator rotates a screw 425, the screw 425 drives the rocker 426 on it to rotate synchronously, and the rocker 426 rotates synchronously with the other synchronous plates 427 connected to this synchronous plate 427 through the connection of the synchronous plate 427, so that the screws 425 in the same group of clamping components 42 can rotate synchronously, simplifying the preliminary adjustment steps.

[0062] It should be noted that, since the distances moved by the clamping plate 421 are different when it rests against the sides of the magnesium ingots placed forward and backward, the angles at which the screws 425 in the two sets of clamping assemblies 42 need to be rotated are different, and thus the screws 425 in the two sets of clamping assemblies 42 need to be adjusted separately.

[0063] After the clamping plate 421 is clamped on the front and rear sides of the magnesium ingot, the telescopic section of the No. 1 electric cylinder is extended again to drive the active plate 51 to move downward, so that the horizontal section of the L-shaped structure at the lower part of the blocking plate 53 rests on the upper side of the magnesium ingot and compresses the coil spring. At this time, the positioning plate 541 no longer blocks the wedge-shaped groove of the blocking plate 53, so that the coil spring has a tendency to push the push plate 521 downward through its own elastic force, thereby making the push plate 521 have a tendency to push the magnesium ingot to the right through the blocking plate 53.

[0064] See Figure 5 A side of the clamping plate 421 close to the corresponding sliding block 422 is provided with a plurality of transversely arranged grooves at equal intervals along the width direction of the clamping plate 421 .

[0065] When the blocking plate 53 compresses the coil spring, the saw blade moves from back to front, so that the saw blade cuts the magnesium ingots one by one from back to front. The separated magnesium ingots can improve the heat dissipation efficiency, prevent excessive heat generated during cutting, and prevent magnesium chips from accumulating and causing the risk of explosion. The grooves on the clamping plate 421 can increase the ventilation area of ​​the clamped position of the magnesium ingot, thereby further reducing the temperature of the magnesium ingot during cutting.

[0066] When the magnesium ingot is cut, the coil spring at the corresponding position pushes the push plate 521 downward by its own elastic force, so that the push plate 521 pushes the cut part of the magnesium ingot to the right through the blocking plate 53, thereby actively eliminating the contact between the magnesium ingot block and the saw blade, effectively protecting the cutting tool, avoiding high-temperature blocks sticking to the saw blade and causing sparks, and further enhancing safety protection in conjunction with the heat dissipation gap.

[0067] See Figure 6 The lower right side of the blocking plate 53 is hinged to a push plate 532 through a hinge plate 531. A torsion spring is arranged between the hinge plate 531 and the blocking plate 53. The torsion spring is not shown in the figure. A conveying roller 533 is rotatably arranged on the base plate 1 corresponding to the position of the push plate 532.

[0068] In the absence of external force, the torsion spring drives the hinge plate 531 to tilt due to its own elastic force, so that the hinge plate 531 tilts gradually from bottom to top and toward the left, and the push plate 532 remains straight under the action of gravity.

[0069] When all the magnesium ingots are cut, the blocking plate 53, the pressure plate 41 and the clamping plate 421 are reset to their initial positions, and then the magnesium ingot is moved to the right again by the pushing mechanism. The magnesium ingot to be cut pushes the cut magnesium ingot block to the right to the conveying roller 533, and then the blocking plate 53 is moved downward again, so that the blocking plate 53 drives the pushing plate 532 to rest on the cut magnesium ingot block through the hinge plate 531.

[0070] Continue to move the blocking plate 53 downward, and the blocking plate 53 moves the push plate 532 to the right through the hinge plate 531. The push plate 532 drives the magnesium ingot block to smoothly move away from the magnesium ingot to be cut along the conveying roller 533, so that the vertical section of the L-shaped structure of the blocking plate 53 can move downward to the right part of the magnesium ingot to be cut, thereby blocking and positioning the right end of the cut magnesium ingot again.

[0071] It should be noted that in order to avoid the impact of dimensional deviation during casting on the clamping effect, a removable rubber pad can be installed on the lower end surface of the pressure plate 41 and the side where the clamping plate 421 contacts the magnesium ingot to compensate for the dimensional deviation of different magnesium ingots and assist in the stable cutting operation.

[0072] See Figures 1 to 7 When cutting the magnesium ingot, the present invention also includes the following steps: In the first step, the operator places the magnesium ingot on the upper part of the base plate 1, and each magnesium ingot is located between two adjacent partition blocks 431, and then pushes the magnesium ingot to the right through the existing pushing structure, so that the magnesium ingot moves to between two adjacent limit plates 43, so that the limit plates 43 and the partition blocks 431 jointly guide the magnesium ingot.

[0073] In the second step, the telescopic section of the No. 1 electric cylinder is extended to drive the active plate 51 to move downward until the vertical section of the L-shaped structure at the bottom of the blocking plate 53 is located to the right of the end of the magnesium ingot. The pushing mechanism pushes the magnesium ingot against the blocking plate 53, so that the right ends of all magnesium ingots are precisely aligned with the same vertical plane, and the pushing positioning error is eliminated through the physical hard limit mechanism.

[0074] In the third step, the telescopic section of the No. 2 electric cylinder is extended to drive the pressure plate 41 to move downward, and then the magnesium ingot blocks the adjusting screw 425, so that the sliding block 422 drives the corresponding two clamping plates 421 to move closer to each other until the pressure plate 41 rests on the upper side of the magnesium ingot, and the two clamping plates 421 are synchronously rested and clamped on the front and rear sides of the magnesium ingot.

[0075] In the fourth step, the telescopic section of the No. 1 electric cylinder is extended to drive the active plate 51 to move downward, so that the horizontal section of the L-shaped structure at the bottom of the blocking plate 53 rests on the upper side of the magnesium ingot and compresses the coil spring, so that the push plate 521 has a tendency to push the magnesium ingot to the right through the blocking plate 53.

[0076] The fifth step is to move the saw blade from back to front to cut the magnesium ingots one by one. When the magnesium ingot is cut, the blocking plate 53 pushes the cut part of the magnesium ingot to the right, thereby actively eliminating the contact between the magnesium ingot block and the saw blade, effectively protecting the cutting tool, avoiding high-temperature blocks sticking to the saw blade and causing sparks, and further strengthening safety protection in conjunction with the heat dissipation gap.

[0077] In the sixth step, after all the magnesium ingots are cut, reset the blocking plate 53, the pressure plate 41 and the clamping plate 421 to their initial positions, then move the magnesium ingot to the right again through the pushing mechanism, and then move the blocking plate 53 downward again, so that the pushing plate 532 drives the magnesium ingot block away from the magnesium ingot to be cut.

[0078] In the seventh step, steps 2 to 6 are repeated to continuously cut the magnesium ingot to a fixed length.

[0079] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, which are still covered by the scope of protection of the present invention.
