Description

Technical Field

[0001] The present invention relates to the technical field of cutting devices, and particularly to a cutting device for metal product processing. Background Art

[0002] In the field of metal product processing, the cutting process is a common processing link, and its cutting accuracy and stability directly affect the final quality of metal products. At present, there are many deficiencies in the existing metal product cutting devices in fixing metal products.

[0003] When the existing cutting devices fix metal products, they usually only constrain from a single direction or a single dimension. The traditional method is to only clamp and fix from the outside of the metal product. During the cutting process, when the cutting force acts on the metal product, the metal product is likely to displace under the action of the cutting force. Because the single clamping and fixing cannot provide sufficient binding force to resist the actions in all directions generated by the cutting force, the cutting position deviates, greatly reducing the cutting accuracy, making the dimensional accuracy of the processed metal products not meet the requirements, increasing the scrap rate, and raising the production cost. Therefore, a cutting device for metal product processing is proposed. Summary of the Invention

A cutting groove corresponding to the cutting blade is formed at the top of the cutting table.

[0023] Compared with the prior art, the present invention adopts the above technical solutions and has the following technical effects:

[0024] 1. Through the rotating roller in the pressing assembly being pushed by the electric cylinder and pressing on the metal product to press and position it, a reliable binding force can be provided, effectively preventing the metal product from shifting under the action of the cutting force, ensuring that the cutting position is accurate, greatly improving the cutting precision. The clamping assembly clamps and fixes the metal product from the outside, and the pressing assembly applies a downward pressure on the metal product from above, forming an all-round constraint in three-dimensional space, so that no matter which direction of the cutting force the metal product is subjected to during the cutting process, it is difficult to move or shake, greatly enhancing the stability of the fixation.

[0025] 2. By using the first motor to drive the first rotating shaft to rotate, and there are two threaded segments with opposite thread directions on the outer side of the first rotating shaft, the two vertical plates threadedly connected to the outer sides of the threaded segments can approach or move away from each other along the first sliding rod in the second sliding groove, which can quickly and smoothly realize the synchronous clamping of both sides of the metal product, improving the stability and accuracy of the clamping, ensuring that the metal product is evenly stressed during the cutting process, and preventing it from tilting or shaking due to uneven stress on one side.

[0026] 3. By the second motor in the adjustment assembly driving the trapezoidal lead screw to rotate, the limiting plate drives the fixed frame and the cutting blade to move horizontally, realizing the preliminary adjustment of the cutting position of the cutting blade, aligning with the part to be cut of the metal product. The electric cylinder pushes the cross plate to drive the cutting blade and related components to move downward for cutting. The sliding column slides in the fourth sliding groove, ensuring the smoothness of the cross plate during the descending process, so that the cutting blade can stably contact the metal product for cutting.

[0027] 4. Through the connecting frame on one side of the protective box driving the transparent protective cover to descend synchronously with the cutting blade, just covering the outside of the cutting table when the cutting blade contacts the metal product, effectively preventing the flying debris from scattering everywhere during cutting, avoiding the debris from harming the operator, and reducing the damage of the debris to the equipment and other components.

[0028] V. When replacing the rotating roller, simply rotate the handwheel. The handwheel drives the second rotating shaft to rotate. By using the threaded connection relationship between the connecting shaft and the insertion groove on the inner wall of the limiting frame, the connecting shaft is disengaged from the insertion groove, and then the connecting shaft and the second rotating shaft can be removed from the inside of the rotating roller, completing the disassembly of the old rotating roller. When installing a new rotating roller, just operate in the reverse direction to thread-connect the connecting shaft with the insertion groove. The entire replacement process does not require complex tools and cumbersome steps, is simple and convenient to operate, greatly shortens the equipment downtime, and improves the production efficiency.

[0042] Embodiment

[0043] Please refer to Figures 1-9, the present invention provides a technical solution: a cutting device for metal product processing, including a cutting table 1. Four corners of the top of the cutting table 1 are fixed with support frames 8. A cutting blade 6 for cutting and processing metal products is provided on the lower side of the support frames 8; a protection component 2 is provided outside the cutting table 1, and the protection component 2 is used to block the flying debris during cutting; on one side of the protection component 2, an adjustment component 5 for adjusting the cutting position of the cutting blade 6 is provided, and on one side of the adjustment component 5, a pressing component 7 for pressing and positioning is provided; under the action of the adjustment component 5, the protection component 2 moves with the movement of the cutting blade 6. The transparent protective cover 21 shields the outside of the cutting table 1 to prevent debris from splashing during cutting. At the same time, the operator can observe the cutting situation through the transparent protective cover 21. On one side of the cutting table 1, a clamping component 3 for clamping and fixing metal products is provided;

[0044] The adjustment component 5 includes a second motor 51 and a fixing frame 510. A fourth chute 59 is opened on one side of the bottom of the fixing frame 510. A sliding column 57 is slidably connected inside the fourth chute 59. The bottom of the sliding column 57 is fixed with a cross plate 511. The bottom of the cross plate 511 is bolted with a protective box 512. A third motor 9 is fixed on the inner wall of the protective box 512; the output shaft end of the second motor 51 is fixed with a trapezoidal lead screw 54. A protective frame is fixed on the top of the support frame 8 outside the trapezoidal lead screw 54. A limiting plate 53 is threadedly connected to the outside of the trapezoidal lead screw 54. An electric cylinder 58 is fixed on the inner wall of the fixing frame 510. The trapezoidal lead screw 54 is made of alloy steel and its surface is chrome-plated to improve its wear resistance and corrosion resistance. The electric cylinder 58 drives the cross plate 511 and the cutting blade 6 to move up and down through a push rod. The cutting reaction force generated during this process is borne by the sliding column 57 and the fourth chute 59 and will not be directly transmitted to the trapezoidal lead screw 54.

[0045] The output shaft end of the third motor 9 is fixed at one end of the axis of the cutting blade 6. Heat dissipation holes are opened on the outside of the protective box 512. The push rod end of the electric cylinder 58 is fixed on the top of the cross plate 511; when the push rod end of the electric cylinder 58 extends, the cutting blade 6 moves downward to cut the metal product. Two connecting plates 55 are fixed on the top of the support frame 8. A second sliding rod 52 that is movably inserted into one side of the limiting plate 53 is fixed between the two connecting plates 55. A third chute 56 that is slidably connected to the outside of the limiting plate 53 is opened on one side of the support frame 8.

[0046] The outside of the trapezoidal lead screw 54 is rotatably connected to one side of the connecting plate 55 through a bearing. One side of the second motor 51 is fixed on the top side of the support frame 8. The top of the fixing frame 510 is fixed to the bottom of the limiting plate 53. The protection component 2 includes a transparent protective cover 21, such as Figure 4 The transparent protective cover 21 is sleeved outside the cutting table 1 without interference. A bracket 23 is fixed on the inner wall of the transparent protective cover 21. The shape of the bracket 23 is a square frame, and a limiting block 24 is fixed on one side of the bracket 23.

[0047] A connecting frame 22 is fixed to one side of the protective box 512. A limiting groove 25 is formed on one side of the connecting frame 22, and the inner wall of the limiting groove 25 is connected to a limiting block 24 by bolts. When the electric cylinder 58 pushes the transparent protective cover 21 downward to block the outside of the cutting table 1, the transparent protective cover 21 blocks the flying debris during cutting. The transparent material of the transparent protective cover 21 enables the operator to clearly observe the cutting situation during the cutting process, promptly discover cutting abnormalities and make corresponding adjustments, ensuring safety protection while not affecting the operator's monitoring and operation of the cutting process.

[0048] The clamping assembly 3 includes two first motors 31. A first rotating shaft 39 is fixed to the output shaft end of the first motor 31. Two thread segments 36 with opposite thread directions are provided on the outer side of the first rotating shaft 39. A vertical plate 38 is threadedly connected to the outer side of the thread segment 36. A fixing plate 35 is fixed to one side of the vertical plate 38. Two second chutes 310 are formed inside the cutting table 1. When the first motor 31 and the first rotating shaft 39 of the clamping assembly 3 rotate, the vertical plates 38 on the thread segments 36 slide along the first sliding rod 37, the first chute 34, and the second chute 310, so that the push plates 32 approach each other, and the rubber plates 33 contact the metal product, realizing clamping and fixing to prevent the metal product from moving during cutting.

[0049] The inner wall of the second chute 310 is provided with a first chute 34 that is slidably connected to the outside of the fixing plate 35. A push plate 32 is fixed to one side of the fixing plate 35. A rubber plate 33 is bonded to one side of the push plate 32. A first sliding rod 37 that movably penetrates one side of the vertical plate 38 is fixed to the inner wall of the second chute 310. The rubber plate 33 contacts the metal product. The rubber plate 33 has good elasticity and buffering performance and can play a buffering role during the clamping process, avoiding damage such as indentations and scratches on the surface of the metal product caused by excessive clamping and protecting the appearance quality of the metal product. The reaction forces of the metal product on the two side push plates 32 are transmitted to the thread segments 36 through the vertical plate 38. Due to the opposite thread directions, the loads on both sides form a balanced force system on the first rotating shaft 39, effectively offsetting the radial bending moment and avoiding bending deformation caused by unilateral force.

[0050] When the vertical plates 38 approach each other, the push plates 32 clamp and fix the outside of the metal product. After placing the position of the metal product to be cut on the top of the cutting groove 4, the metal product is clamped and fixed by the clamping assembly 3, which can accurately determine the cutting part, provide a stable and accurate basis for subsequent cutting operations, effectively avoid the offset of the metal product during cutting, and ensure the cutting accuracy.

[0051] The pressing assembly 7 includes two limit frames 72. A second rotating shaft 75 is inserted into one side of the limit frame 72. A handwheel 71 and a connecting shaft 76 are respectively fixed at both ends of the second rotating shaft 75. An insertion groove 77 is formed in the inner wall of the limit frame 72. The inner side of the insertion groove 77 is threadedly connected to the outer side of the connecting shaft 76. A rubber block 78 is bonded to the inner wall of the insertion groove 77. The rubber block 78 generates a radial pressure through its own elastic deformation, making the thread pair between the connecting shaft 76 and the insertion groove 77 contact more tightly, increasing the frictional torque between the threads. The friction force can effectively resist the loosening tendency caused by vibration or impact during the operation of the equipment.

[0052] A rotating roller 73 is rotatably connected to the outer side of the second rotating shaft 75. One side of the limit frame 72 is fixed to the outer side of the protective box 512. The two limit frames 72 are vertically distributed with the connecting frame 22. One side of the first motor 31 is fixed to one side of the cutting table 1. A cutting groove 4 corresponding to the cutting blade 6 is formed at the top of the cutting table 1. When the second motor 51 in the adjusting assembly 5 is started, it drives the trapezoidal lead screw 54 to rotate, so that the limit plate 53 slides along the second slide bar 52 and the third chute 56 to determine the horizontal cutting position of the cutting blade 6. The push rod end of the electric cylinder 58 extends, pushing the cross plate 511 and the protective box 512 to move downward, and at the same time driving the cutting blade 6 to move downward. The third motor 9 is started to drive the cutting blade 6 to rotate, realizing the cutting of the metal product.

[0053] Working principle: When cutting a metal product, place the position of the metal product to be cut on the top of the cutting groove 4. First, clamp and fix the metal product through the clamping assembly 3. Start the two first motors 31. The first motors 31 drive the first rotating shafts 39 to rotate. Since there are two thread segments 36 with opposite thread directions on the outer side of the first rotating shafts 39, when the first rotating shafts 39 rotate, the two vertical plates 38 threadedly connected to the outer sides of the thread segments 36 will move closer to or away from each other along the first slide bars 37 in the second chutes 310. The vertical plates 38 drive the fixing plates 35 to move, and the fixing plates 35 drive the push plates 32 to move. The rubber plates 33 on the push plates 32 contact the metal product, thereby clamping and fixing the outer side of the metal product. The rubber plates 33 play a role in increasing friction and buffering, preventing damage to the metal product due to excessive clamping.

[0054] When cutting is required, start the second motor 51 in the adjusting assembly 5. The output shaft of the second motor 51 drives the trapezoidal lead screw 54 to rotate. The limit plate 53 threadedly connected to the outer side of the trapezoidal lead screw 54 moves along the direction of the second slide bar 52 and the third chute 56 under the action of screw drive, thereby driving components such as the fixing frame 510 and the cutting blade 6 below to move horizontally, realizing the preliminary adjustment of the cutting position of the cutting blade 6 to align it with the part of the metal product to be cut.

[0055] After the cutting position is determined, the electric cylinder 58 is started, and the push rod end of the electric cylinder 58 extends, pushing the cross plate 511 downward. The sliding column 57 slides in the fourth chute 59 to ensure the stable descent of the cross plate 511. The cross plate 511 drives the protective box 512 and the third motor 9 and the cutting blade 6 fixed in the protective box 512 to move downward together. At the same time, the connecting frame 22 on one side of the protective box 512 drives the transparent protective cover 21 downward. When the cutting blade 6 touches the metal product and cuts it, the transparent protective cover 21 just blocks the outside of the cutting table 1 to prevent the flying debris from scattering everywhere during cutting. The output shaft end of the third motor 9 is fixed at the axis of the cutting blade 6. The third motor 9 is started to drive the cutting blade 6 to rotate at a high speed to cut and process the metal product. The transparent protective cover 21 can effectively block the flying debris during cutting to prevent the debris from hurting people. At the same time, the transparent material of the transparent protective cover 21 is convenient for the operator to observe the cutting situation.

[0056] To prevent the metal product from moving or shaking under the action of the cutting force, when the push rod end of the electric cylinder 58 extends, it drives the protective box 512 and the pressing assembly 7 to move downward synchronously. The rotating roller 73 first touches the surface of the metal product, and then the cutting blade 6 completes the cutting action to further press and position the metal product, ensuring that the metal product will not move during the cutting process and guaranteeing the cutting accuracy.

[0057] When the rotating roller 73 needs to be replaced, only need to rotate the hand wheel 71. The hand wheel 71 drives the second rotating shaft 75 to rotate. One end of the connecting shaft 76 of the second rotating shaft 75 rotates in the insertion groove 77 on the inner wall of the limiting frame 72. Since the inner side of the insertion groove 77 is threadedly connected to the connecting shaft 76, the connecting shaft 76 will leave the inner side of the insertion groove 77. Then, the connecting shaft 76 and the second rotating shaft 75 are taken out from the inside of the rotating roller 73. At this time, the rotating roller 73 can be removed. The rubber block 78 abuts against one side of the connecting shaft 76 to prevent the second rotating shaft 75 from loosening, so that the metal product is more stably pressed, ensuring the cutting accuracy and quality.

[0058] Take a new rotating roller 73, insert the connecting shaft 76 and the second rotating shaft 75 into the inside of the rotating roller 73, and make the connecting shaft 76 threadedly connected to the insertion groove 77, then the installation of the rotating roller 73 can be completed.

[0059] In summary, by using the first motor 31 to drive the first rotating shaft 39 to rotate, and there are two thread segments 36 with opposite thread directions on the outside of the first rotating shaft 39, the two vertical plates 38 threadedly connected to the outside of the thread segments 36 can approach or move away from each other along the first slide rod 37 in the second chute 310, which can quickly and stably realize the synchronous clamping of both sides of the metal product, improving the clamping stability and accuracy, ensuring that the metal product is evenly stressed during the cutting process and will not tilt or shake due to uneven unilateral stress.

[0060] By adjusting the rotation of the trapezoidal lead screw 54 driven by the second motor 51 in the adjustment component 5, the limit plate 53 drives the fixed frame 510 and the cutting blade 6 to move horizontally, realizing the preliminary adjustment of the cutting position of the cutting blade 6, aligning the part to be cut of the metal product. The electric cylinder 58 pushes the cross plate 511 to drive the cutting blade 6 and related components to move downward for cutting. The sliding column 57 slides in the fourth sliding groove 59, ensuring the smoothness of the downward movement of the cross plate 511, so that the cutting blade 6 can stably contact the metal product for cutting.

[0061] The connecting frame 22 on one side of the protective box 512 drives the transparent protective cover 21 to descend synchronously with the cutting blade 6. When the cutting blade 6 contacts the metal product, it just blocks the outside of the cutting table 1, effectively preventing the flying debris from scattering everywhere during cutting, avoiding the debris from causing harm to the operator, and reducing the damage of the debris to the equipment and other components.

[0062] Through the rotating roller 73 in the pressing component 7 being pushed by the electric cylinder 58 and pressing on the metal product for pressing and positioning, it can provide a reliable binding force, effectively preventing the metal product from displacing under the action of the cutting force, ensuring the cutting position is accurate, greatly improving the cutting accuracy. The clamping component 3 clamps and fixes the metal product from the outside, and the pressing component 7 applies a downward pressure on the metal product from above, forming an all-round constraint in the three-dimensional space, so that no matter which direction the cutting force acts on the metal product during cutting, it is difficult to move or shake, greatly enhancing the stability of the fixation.

[0063] When replacing the rotating roller 73, only need to rotate the hand wheel 71. The hand wheel 71 drives the second rotating shaft 75 to rotate. Utilizing the threaded connection relationship between the connecting shaft 76 and the insertion groove 77 on the inner wall of the limit frame 72, the connecting shaft 76 can be separated from the insertion groove 77, and then the connecting shaft 76 and the second rotating shaft 75 can be taken out from the inside of the rotating roller 73 to complete the disassembly of the old rotating roller 73; when installing a new rotating roller 73, just operate in the reverse direction to thread the connecting shaft 76 with the insertion groove 77. The whole replacement process does not require complex tools and cumbersome steps, is simple and convenient to operate, greatly shortens the equipment downtime, and improves the production efficiency.
