Description

Technical Field

[0001] This invention belongs to the field of shearing machine tool technology, and specifically relates to a shearing machine tool for processing metal billets. Background Technology

[0002] Metal shearing machine tools are metal processing equipment that integrates mechanical transmission, intelligent control and modular design. Their core function is to achieve efficient, precise and fixed-length cutting of metal raw materials (such as plates, bars, tubes and profiles) of different specifications and materials by dynamically adjusting shearing parameters (such as shearing gap, cutting speed, shearing angle, etc.), while meeting the strict requirements of the metal processing industry for production efficiency, product standardization and operational safety.

[0003] Currently, the conventional processing flow of mainstream automated metal shearing machine tools on the market is as follows: the operator sets the shearing length and cutting speed through the touch screen, places the stack or single piece of metal blanks at the feeding station of the equipment, the equipment automatically pushes the blanks to the shearing area, the clamps on both sides automatically clamp the blanks to prevent deviation, the blade assembly reciprocates according to the set frequency to complete the cutting action, and the sheared finished workpieces naturally slide down to the collection box or conveyor belt below. The operator stops the machine regularly to clean the blade edges and the metal debris and burrs accumulated in the feeding channel.

[0004] However, in actual production, it has been found that existing metal shearing machine tools have significant problems with material feeding during continuous processing. During shearing, the cutting edge of the tool violently crushes and breaks the metal material, generating a large number of fine metal chips, burrs, and tiny adhering substances. These chips easily adhere tightly to the cutting edge of the tool, the working surface of the adjusting plate, and the surface of the feeding slide due to static electricity or compression. As the processing time increases, the adhesion layer gradually thickens, not only causing changes in the actual spacing of the adjusting plate and affecting the cutting length accuracy of subsequent workpieces, but more seriously, the adhering substances can block the feeding channel, preventing the cut workpieces from sliding smoothly under their own weight, resulting in jamming, accumulation, or even stacking. This forces operators to frequently stop the machine for cleaning, significantly reducing the continuous operation efficiency of the production line and increasing manual intervention costs and safety risks.

[0016] The beneficial effects of this invention are as follows: 1. The shearing machine tool for processing metal billets according to the present invention, through the clamping assembly, when the cutter descends to slice, the two clamping plates move closer to each other, tightly clamping the metal from both sides and accurately positioning the metal at the center position on the shearing table surface, avoiding positional displacement of the metal due to the force of the cutter during slicing. When the cutter rises to reset, the two clamping plates move away from each other, releasing the clamping force on the remaining metal.

[0017] 2. The shearing machine tool for processing metal billets according to the present invention has a clamping assembly that is applicable to different sizes of metals. Metals of any size can be precisely and stably clamped by the flexible movement of the clamping plate driven by magnetic force. It can also avoid damage to the surface or internal structure of the metal due to excessive clamping force or excessive impact force. Compared with the large impact force that may be generated by some rigid mechanical transmissions, this clamping method has less impact on the metal and will not damage the surface or internal structure of the metal due to excessive clamping force or excessive impact force, thus ensuring the integrity and appearance quality of the metal.

[0018] 3. The shearing machine tool for processing metal billets according to the present invention, through the desorption component, when the cutter completes a slicing and rises to reset, it drives the desorption component to move. The desorption component can simultaneously clean the cutter and the side of the adjusting plate that may be attached to the metal. The distance between the adjusting plate and the shearing table determines the thickness of the metal slice. If there are metal sheets attached to the side of the adjusting plate, it will change the actual slicing distance. Metal sheets attached to the side of the cutter may also affect the cutting effect and the uniformity of the thickness of subsequent slices. By cleaning the attached metal sheets, the desorption component prevents them from having an adverse effect on the actual slicing distance and the uniformity of the thickness of subsequent slices, so that the thickness of each slice of metal is uniform and consistent, thus improving the stability and reliability of the entire adjustable slicing device.

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 10 As shown, the present invention provides a technical solution: a shearing machine tool for processing metal billets, including a base table 1, a shearing table 2 fixedly connected above the base table 1, electronic telescopic rods 5 symmetrically fixedly connected to one side of the shearing table 2, an adjusting plate 6 fixedly connected between one end of the electronic telescopic rods 5, scale plates 7 fixedly connected to both sides of the shearing table 2, a cutting tool 4 arranged above the shearing table 2, a lifting plate 3 fixedly connected above the cutting tool 4, a drive assembly for continuously lifting and lowering the lifting plate 3 arranged on the side of the lifting plate 3, a pushing assembly for feeding metal arranged on the surface of the shearing table 2, a clamping assembly arranged above the shearing table 2, the clamping assembly including two clamping plates 8 that can open and close relative to each other, and a desorption assembly arranged on one side of the cutting tool 4, the desorption assembly being able to simultaneously clean metal sheets that may be adhered to the cutting tool 4 and the side of the adjusting plate 6.

[0024] During operation: First, adjust the position of the adjusting plate 6 according to the required slicing thickness of the metal to be sliced. The distance between the adjusting plate 6 and the shearing table 2 is the slicing thickness. The position of the adjusting plate 6 can be flexibly adjusted by the electronic telescopic rod 5, and the specific value of the slicing thickness can be clearly read by the scale plate 7. After adjusting the position of the adjusting plate 6, first pull the pusher assembly to make room for the metal on the surface of the shearing table 2. Then place the metal to be sliced ​​on the shearing table 2, and the metal is located between the two clamping plates 8. Then release the pusher assembly. At this time, under the pushing force of the pusher assembly, one end of the metal is tightly pressed against one side of the adjusting plate 6, preparing for the subsequent slicing operation. Next, the drive assembly lowers the cutter 4 via the lifting plate 3 to slice the metal. Just as the cutter 4 begins its descent and before it contacts the metal, the clamping assembly is triggered. This clamping assembly moves the two clamping plates 8 closer together, clamping both sides of the metal and positioning it at the center of the shearing table 2 surface, ensuring cutting accuracy and preventing metal displacement during slicing. After the first slice, the drive assembly raises the cutter 4 to reset. This process moves the de-adhesion assembly, cleaning any metal pieces that may adhere to the sides of the cutter 4 and the adjusting plate 6, preventing them from affecting the actual slicing spacing and the uniformity of subsequent slice thickness. Once the cutter 4 returns to its initial position, the force on the clamping assembly is released, and the two clamping plates 8 move away from each other back to their original positions, no longer clamping the metal. The remaining metal is automatically pushed forward by the pushing assembly, with one end again pressing against the side of the adjusting plate 6 for the second round of slicing. This cycle continues until the metal slicing is complete. Through the above embodiments, when the blade 4 descends to slice, the two clamping plates 8 move closer to each other via the clamping assembly, tightly clamping the metal from both sides and precisely positioning the metal at the center of the shearing table 2 surface. This prevents the metal from shifting position due to the force of the blade 4 during slicing. When the blade 4 rises to reset, the two clamping plates 8 move away from each other, releasing the clamping force on the remaining metal. Combined with the pushing assembly, the remaining metal can automatically advance forward to continue replenishing the cutting position, preparing for the next round of slicing, thus improving production efficiency and enabling a continuous slicing process. Through the desorption assembly, when the blade 4 completes one cut... When the blade rises and resets, it drives the desorption component to move. The desorption component can simultaneously clean the metal sheets that may be stuck to the sides of the blade 4 and the adjusting plate 6. The distance between the adjusting plate 6 and the shearing table 2 determines the thickness of the metal slices. If there are metal sheets stuck to the sides of the adjusting plate 6, it will change the actual slicing distance. Metal sheets stuck to the sides of the blade 4 may also affect the cutting effect and the uniformity of the thickness of subsequent slices. By cleaning the stuck metal sheets, the desorption component prevents them from having an adverse effect on the actual slicing distance and the uniformity of the thickness of subsequent slices, so that the thickness of each slice of metal is uniform and consistent, thus improving the stability and reliability of the entire adjustable slicing device.

[0025] like Figure 4 As shown, the drive assembly includes a dual-axis motor 14, which is fixedly mounted on the top of the base platform 1. Both output shafts of the dual-axis motor 14 are fixedly connected to sector gears 15. Side plates 12 are fixedly connected to both sides of the lifting plate 3. A rack plate 13 is fixedly connected to one side of each side plate 12. The teeth of the sector gears 15 can mesh with the teeth of the rack plate 13. Springs 16 are fixedly connected between the bottom of the side plates 12 and the top of the base platform 1.

[0026] During operation: When the dual-axis motor 14 is started, its two output shafts begin to rotate synchronously, and the sector gear 15 rotates accordingly. During the rotation of the sector gear 15, when its toothed part contacts and meshes with the rack plate 13, it pushes the rack plate 13 to move downward. The rack plate 13, through the side plate 12, drives the lifting plate 3 and the cutter 4 to descend together for slicing. At the same time, the downward movement of the side plate 12 compresses the second spring 16, causing it to undergo elastic deformation and store elastic potential energy. As the dual-axis motor 14 continues to rotate, when the sector gear 15 rotates... When the toothless part is opposite the rack plate 13, the sector gear 15 loses its meshing with the rack plate 13. At this time, the compressed spring 16 will release its elastic potential energy to return to its original state, generating an upward elastic force on the side plate 12, pushing the side plate 12 to move upward, and then driving the lifting plate 3 and the cutter 4 to move upward and reset. When the sector gear 15 rotates to the toothed part and meshes with the rack plate 13 again, the above process of driving the cutter 4 to descend and slice will be repeated. This cycle is repeated to realize the continuous lifting and lowering movement of the cutter 4 to complete the continuous slicing of metal.

[0027] like Figures 2 to 3 As shown, the pushing assembly includes a pushing plate 9, which is slidably connected to the surface of the shearing table 2. The two sides of the pushing plate 9 slide with the inner groove of the clamping plate 8 respectively. A pull rod 10 is fixedly connected to one side of the pushing plate 9. The pull rod 10 is inserted into the inner wall of the shearing table 2. A spring 11 is provided on the outside of the pull rod 10. The spring 11 is fixedly connected between the shearing table 2 and the side of the pushing plate 9.

[0028] During operation: In the initial state, the pusher plate 9 is pressed tightly against the deepest part of the inner groove of the clamping plate 8 under the elastic force of the spring 11. When metal needs to be placed on the surface of the shearing table 2, the operator needs to hold the pull rod 10 and pull it outward. Under the action of external force, the pusher plate 9 overcomes the elastic force of the spring 11 and slides smoothly away from the adjusting plate 6 along the surface of the shearing table 2. At the same time, both sides of the pusher plate 9 slide synchronously in the inner groove of the clamping plate 8. As the pusher plate 9 moves, the space originally occupied by the pusher plate 9 on the surface of the shearing table 2 is gradually freed up, forming an area for placing metal. After the metal is placed, the pull rod 10 is released. Under the restoring elastic force of the spring 11, the spring 11 will push the pusher plate 9 to slide along the surface of the shearing table 2 towards the adjusting plate 6. During the movement, the pusher plate 9 will gradually contact the metal and eventually push one end of the metal tightly against one side of the adjusting plate 6, so that the metal is in a suitable cutting starting position.

[0029] like Figures 5 to 6 As shown, the clamping assembly also includes two magnet strips 17, and the two clamping plates 8 are slidably connected to the inner groove of the shearing table 2. The two magnet strips 17 are respectively fixedly connected to one side of the bottom of the two clamping plates 8. A magnet block 18 is fixedly connected to one side of the side plate 12. The two magnet blocks 18 are respectively located on one side of the two magnet strips 17 and the adjacent surface magnetism is the same pole.

[0030] During operation: In the initial state, the magnet block 18 is located above and to the side of the magnet strip 17, with no interaction between them and not within the influence range of each other's magnetic forces. The two clamping plates 8 are in a relatively loose state. When the side plate 12 begins to descend for slicing, it will drive the magnet block 18 to descend synchronously. When the magnet block 18 descends and enters the magnetic influence range of the magnet strip 17, since the adjacent surfaces of the magnet block 18 and the magnet strip 17 have the same polarity, according to the principle of like poles repulsion, the magnet block 18 will generate a repulsive force on the magnet strip 17, causing the magnet strip 17 to move away from the magnet block 18 under the action of the repulsive force. The movement of the magnet strip 17 will drive the two clamping plates 8 to move closer to each other along the inner groove of the shearing table 2, thereby clamping the metal tightly from both sides. This clamping method is applicable to metals of different sizes. Metals of any size can be precisely and stably clamped by the flexible movement of the clamping plate 8 driven by magnetic force. It can also avoid damage to the surface or internal structure of the metal due to excessive clamping force or impact. Compared with the large impact force that may be generated by some rigid mechanical transmissions, this clamping method has less impact on the metal and will not damage the surface or internal structure of the metal due to excessive clamping force or impact, thus ensuring the integrity and appearance quality of the metal.

[0031] like Figures 5 to 6 As shown, springs 19 are fixedly connected to the side of the magnet strip 17 away from the magnet block 18, and the ends of the springs 19 away from the magnet strip 17 are fixedly connected to the side of the shearing table 2.

[0032] During operation: When the side plate 12 drives the cutter 4 to descend for slicing, the magnet block 18 enters the magnetic field of the magnet strip 17. Because the adjacent surfaces of the two repel each other, the magnet strip 17 is repelled and moves, which in turn squeezes the spring 3 19 fixed on the side away from the magnet block 18, causing the spring 3 19 to deform and store elastic potential energy. When the side plate 12 drives the cutter 4 to rise and reset, the magnet block 18 rises synchronously, but is still within the magnetic field of the magnet strip 17. At this time, the two clamping plates 8 continue to clamp the remaining metal to ensure that the position of the remaining metal is stable. During the rise of the cutter 4, the desorption component is triggered first. After the metal pieces that may be stuck to the adjusting plate 6 and the side of the cutter 4 are completely cleaned, the side plate 12 continues to rise until it returns to its original position. At this time, the magnet block 18 completely leaves the magnetic field of the magnet strip 17, and the spring 3 19 releases the stored elastic potential energy, pushing the magnet strip 17 and the clamping plate 8 to reset, releasing the clamping force on the remaining metal, creating conditions for the pushing component to push the remaining metal forward, so that the entire workflow can be smoothly connected and advanced.

[0033] like Figures 7 to 10 As shown, the desorption assembly includes a support member 20, which is fixedly connected to the top of the base platform 1. A fixed plate 21 is fixedly connected to the outer wall of the shaft of the support member 20. A rotating shaft 22 is rotatably connected to the inner wall of one end of the fixed plate 21. A reverse scraper 23 is fixedly connected to the outer wall of the rotating shaft 22. One end of the reverse scraper 23 is a pointed end. Rotation components that drive the rotating shaft 22 to rotate are provided on both sides of the rotating shaft 22.

[0034] During operation: When the side plate 12 rises and resets, it drives the self-rotating component to move. The self-rotating component causes the rotating shaft 22 to rotate. While the rotating shaft 22 is rotating, it drives one end of the anti-scraper 23 to rotate around the rotating shaft 22. While the anti-scraper 23 is rotating, the cutter 4 is moving upward. When the anti-scraper 23 rotates to the appropriate position, its tip will gradually contact the side of the metal sheet attached to the cutter 4 and peel the metal sheet off the cutter 4. When the cutter 4 just completes its upward movement, the metal sheet attached to the cutter 4 has been successfully detached and can fall out from the gap between the shearing table 2 and the adjusting plate 6.

[0035] like Figures 8 to 9 As shown, the desorption assembly also includes an arc-shaped push rod 24, which is fixedly connected to the bottom side of the anti-scraper 23. The end of the arc-shaped push rod 24 away from the anti-scraper 23 is a ball, and the lower scraper 25 is slidably connected to the inner wall of the center of the adjusting plate 6.

[0036] During operation: When the back scraper 23 rotates to clean the metal sheets adhering to the side of the cutter 4, it simultaneously drives the arc-shaped push rod 24 to move. The ball at one end of the arc-shaped push rod 24 then applies downward pressure to the top of the lower scraper 25, forcing the lower scraper 25 to move downward along the inner wall of the center position of the adjusting plate 6. During the downward movement, one end of the lower scraper 25 can scrape off any metal sheets that may be adhering to the side of the adjusting plate 6. Since the metal is positioned on the shearing table 2 by the clamping assembly during slicing... If a metal sheet adheres to one side of the adjusting plate 6, it will also be located at the center of the adjusting plate 6. Therefore, during the downward movement of the lower scraper 25, one end of it can accurately apply the thrust to the metal sheet that may be adhered to the side of the adjusting plate 6, thereby scraping the metal sheet off. In addition, the adjusting plate 6 has a lateral adjustment function, but the ball end of the arc-shaped push rod 24 can always maintain contact with the top of the lower scraper 25, ensuring that the desorption component can still perform its cleaning function normally when the position of the adjusting plate 6 changes.

[0037] like Figure 7 and Figure 10 As shown, the self-rotating component includes two trapezoidal blocks 32, which are fixedly connected to both ends of the rotating shaft 22. A connecting frame 27 is fixedly connected to the other side of the side plate 12. A fixed inner groove seat 28 is fixedly connected to the top of the connecting frame 27. An inner slider 29 is slidably connected to the inner wall of the fixed inner groove seat 28. A trapezoidal block 30 is fixedly connected to one side of the inner slider 29. A spring 31 is fixedly connected between one side of the trapezoidal block 30 and the side of the fixed inner groove seat 28. A limiting rod 33 is fixedly connected to the surface of the fixed plate 21. One end of the limiting rod 33 can abut against one side of the anti-scraper 23.

[0038] During operation: When the side plate 12 descends to perform the slicing task, it simultaneously drives the connecting frame 27 downward, causing the fixed inner groove seat 28 and trapezoidal block 30 to descend together. During the descent of trapezoidal block 30, its bottom inclined surface gradually contacts the top inclined surface of trapezoidal block 32. At this time, because the rotating shaft 22 and the anti-scraping plate 23 are restricted from rotating by the rotation limit rod 33, the trapezoidal block 32 will not rotate when its inclined surface is subjected to the downward pressure of the inclined surface of trapezoidal block 30. In order to pass smoothly through the position of trapezoidal block 32, trapezoidal block 30 will move laterally under the push of the interaction force of the inclined surfaces, and the inner slider 29 will slide along the inner wall of the fixed inner groove seat 28. During this process, the spring 31 is compressed and deformed. When the trapezoidal block 30 descends below the trapezoidal block 32, the trapezoidal block 30 loses the compressive force of the trapezoidal block 32 and moves in the opposite direction under the elastic force of the spring 31, returning to its initial state. After the slicing is completed, the side plate 12 begins to rise and reset. During the rising process, the top plane of the trapezoidal block 30 will contact the bottom plane of the trapezoidal block 32, and the top plane of the trapezoidal block 30 will exert an upward force on the bottom plane of the trapezoidal block 32. Under the action of this force, the trapezoidal block 32 will drive the rotating shaft 22 to rotate around its own axis, thereby causing the anti-scraping plate 23 to rotate, and simultaneously desorbing and cleaning the sides of the cutter 4 and the adjusting plate 6.

[0039] like Figures 8 to 9 As shown, a torsion spring 34 is fixedly connected between the back scraper 23 and the fixed plate 21, and a spring 26 is fixedly connected between the bottom of the lower scraper 25 and the top of the adjusting plate 6.

[0040] During operation: When the reverse scraper 23 rotates, it stretches the torsion spring 34, and when the lower scraper 25 moves down, it squeezes the fourth spring 26. When the trapezoidal block 30 moves up and causes the second trapezoidal block 32 to rotate, after the first trapezoidal block 30 moves up to its initial position, it will disengage from the second trapezoidal block 32. At this time, the reverse scraper 23 and the lower scraper 25 will return to their original state under the elastic force of the corresponding torsion spring 34 and the fourth spring 26, preparing for the subsequent desorption and cleaning of the slices.

[0041] like Figure 1 and Figure 4 As shown, a feeding platform 35 is fixedly installed on the top of the base platform 1. The feeding platform 35 is in an inclined state and is located below the shearing table 2 and the adjusting plate 6. A collection box 36 is provided on one side of the feeding platform 35 and is placed directly above the base platform 1.

[0042] During operation: After slicing and desorption, the metal sheets will fall onto the inclined surface of the unloading platform 35 and flow through the inclined surface into the collection box 36 for collection.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.
