Description

Technical Field

[0001] The invention relates to the technical field of metal cutting, and in particular to a metal cutting device for machining mechanical equipment. Background Art

[0002] Metal cutting, as a key material removal and forming method in metal forming process, still occupies a core position in the current mechanical manufacturing field. This process involves the interaction between the workpiece and the tool. The tool accurately removes excess metal from the workpiece to be processed to ensure that the workpiece meets the design requirements of geometric accuracy, dimensional accuracy and surface quality while meeting productivity and cost control. The realization of this process depends on the relative movement between the workpiece and the tool, that is, the cutting movement, which is usually provided by metal cutting machine tools.

[0003] For example, in the prior art, there is a metal sheet cutting device for mechanical processing with publication number CN119036086A. The cutting device clamps the metal sheet by moving the first stop block, and combines the inclined rod and the transmission block to link the second stop block and the third stop block to move synchronously, and cooperates with the transmission frame. Although it can achieve multi-sided clamping of the metal sheet to enhance the cutting stability and ensure the flatness of the incision, the first stop block links the second stop block and the third stop block to move synchronously, which can only achieve multi-sided stable clamping effect for metal sheets of fixed sizes. When clamping metal sheets with different thickness-to-width ratios, it is difficult to ensure that the three groups of stops can adaptively adjust the stable clamping of each side of the metal sheet, thereby affecting the stable cutting processing of metal sheets of different sizes.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Embodiment 1: Please refer to Figures 1 - 7 As shown, in view of the problem that when clamping metal plates with different thickness-width ratios in the prior art, it is difficult to ensure that the three sets of abutting blocks perform adaptive adjustment and stable clamping on each surface of the metal plate, thereby affecting the stable cutting process of metal plates of different sizes, the following solutions can be adopted to solve the problem:

[0038] In this embodiment, a metal cutting device for mechanical equipment processing includes a feeding table 1, which is used for conveying metal plates. Inside the feeding table 1, there is a fixed connection with a first supporting plate, and two sets of first rollers rotatably connected on both sides of the first supporting plate. A feeding conveyor belt that slides with the first supporting plate is drivingly connected between the first rollers. The first supporting plate is used to enhance the horizontal supporting effect of the feeding conveyor belt on the metal plates, and a fixed frame 11 fixedly connected to the feeding table 1. An adaptive multi-directional clamping unit 2 is arranged on the fixed frame 11;

[0039] On one side of the feeding table 1, there are a fixed table 12 and a movable table 13. The set fixed table 12 and movable table 13 are used for supporting and processing the cut metal plates. And clamping processing units 3 are arranged on both the fixed table 12 and the movable table 13, which are used for diversified post-processing of the cutting surfaces on both sides of the cut metal plates to improve the quality of the cut metal plates. A pushing unit 4 is arranged on the fixed table 12, which is used to load the cut metal plates onto the clamping processing unit 3;

[0040] The adaptive multi-directional clamping unit 2 includes a pressure seat 21, and an L-shaped toothed plate 22 that slides relative to each other inside the pressure seat 21. Trapezoidal grooves are formed on the toothed side wall of the L-shaped toothed plate 22, and a trapezoidal block is fixedly installed on the L-shaped toothed plate 22 to enhance the stable sliding effect of the L-shaped toothed plate 22 in the pressure seat 21. A clamping plate 23 is slidably connected to the L-shaped toothed plate 22. Through the sliding connection between the L-shaped toothed plate 22 and the clamping plate 23, when the pressure seat 21 descends to squeeze the metal plate, it can achieve the effect of multi-faceted stable clamping of metal plates with different thickness-width ratios;

[0041] A tension spring 24 is fixedly connected between the top of the L-shaped toothed plate 22 and the clamping plate 23. The setting of the tension spring 24 is used for the clamping plate 23 to assist in relative downward movement and resetting when the pressure seat 21 rises. The clamping processing unit 3 includes a lower conveying table 31 fixedly connected to the fixed table 12 and the movable table 13. Inside the lower conveying table 31, there is a fixed connection with a second supporting plate, and two sets of second rollers rotatably connected on both sides of the second supporting plate. A lower discharge conveyor belt that slides with the second supporting plate is drivingly connected between the second rollers. The second supporting plate is used to enhance the horizontal supporting effect of the lower discharge conveyor belt on the metal plates;

[0042] And a U-shaped bracket 32 is fixedly connected to the lower conveying table 31. Two motors are installed on the U-shaped bracket 32, and a wire brush disc 33 and a grinding disc 34 are respectively arranged on the output shafts of the two motors. Through the independent driving of the two motors, the wire brush disc 33 first removes the cutting burrs on the cutting surface of the metal plate, and then the grinding disc 34 performs fine grinding on the saw marks on the cutting surface. This continuous operation process not only improves the processing efficiency but also significantly improves the quality of the cutting surface, making the final product more in line with the usage requirements.

[0043] Above the blank holder 21, there is a push plate 25, and an electric push rod 26 is installed between the push plate 25 and the fixed frame 11. A plurality of guide rods, which are fixedly connected to the top of the push plate 25 and are distributed in a rectangle and slide with the fixed frame 11, are provided to increase the stability of the push plate 25 during the lifting process. A limit guide plate 27, which slides with the blank holder 21, is welded to the bottom of the push plate 25 for a stable sliding effect between the push plate 25 and the blank holder 21;

[0044] And a blank holding spring 28 is installed between the push plate 25 and the blank holder 21. After the blank holder 21 contacts the metal sheet, when the push plate 25 moves downward, the blank holder 21 is caused to generate a certain clamping force on the metal sheet in cooperation with the feeding table 1, and interference with the movement of the push plate 25 is avoided.

[0045] The L-shaped tooth plate 22 is slidably connected to the blank holder 21, and a rotating rod 29 is rotatably connected to the inside of the blank holder 21. A gear 210, which is fixedly connected to the rotating rod 29 and meshes with the L-shaped tooth plate 22, is provided. The rotating rod 29 drives the gear 210 to rotate, and the gear 210 drives two groups of clamping plates 23 to move relative to each other through the two groups of L-shaped tooth plates 22 meshing therewith to clamp and fix the metal sheet. A plurality of auxiliary balls are rotatably embedded at the bottom of the clamping plate 23 for assisting the relative clamping movement of the clamping plate 23 on the feeding table 1.

[0046] Guide pins 211 are symmetrically and fixedly connected to both sides of the rotating rod 29. A sleeve 212, which slides with the rotating rod 29, is fixedly connected to the bottom of the push plate 25. A spiral guide groove 213, which is matched with the guide pin 211, is formed on the inner wall of the sleeve 212. The electric push rod 26 drives the push plate 25 to move downward, and the push plate 25, combined with the blank holding spring 28, causes the blank holder 21 to move downward and elastically press against the top of the metal sheet;

[0047] As the push plate 25 continues to move downward to compress the blank holding spring 28, the sleeve 212 moves downward relative to the rotating rod 29, and with the guidance of the spiral guide groove 213 on the guide pin 211, the rotating rod 29 is caused to drive the gear 210 to rotate. The gear 210 drives the two groups of L-shaped tooth plates 22 meshing on both sides to carry the clamping plates 23 to move relative to each other to position and center the elastically pressed metal sheet.

[0048] An electric slide 14 is fixedly installed at the bottom of one side of the feeding table 1, and a fixed seat 15 is installed on the slide of the electric slide 14. A reciprocating cutting saw 16 is fixedly installed on the fixed seat 15. The electric slide 14 drives the fixed seat 15 to carry the reciprocating cutting saw 16 to move, and the reciprocating cutting saw 16 performs cutting treatment on the metal sheet clamped in multiple directions and stably;

[0049] An auxiliary pressing plate 214 that cooperates with the fixed table 12 is fixedly connected to the blank holder 21. The auxiliary pressing plate 214 is synchronously carried by the blank holder 21 to move, and combined with the movable table 13, the metal plate on the other side of the reciprocating cutting saw 16 is subjected to extrusion fixation treatment, which can further avoid the problem that the shaking of the cut metal plate affects the flatness of the cut surface.

[0050] A slide bar that slides with the movable table 13 is fixedly connected to the fixed table 12, which is used to increase the installation effect of the movable table 13 on the fixed table 12. A screw rod 17 that is threadedly connected to the movable table 13 is rotatably connected to the fixed table 12. The free end of the screw rod 17 is fixedly connected with a torsion wheel. By adjusting the distance between the movable table 13 and the fixed table 12, the positioning cutting of metal plates with different cutting lengths can be realized, as well as the diversified processing of both sides after different cutting lengths. A positioning plate 18 is fixedly connected to the top of the movable table 13;

[0051] When the clamping plates 23 move relative to each other to position and center the elastically squeezed metal plate, combined with the rotation of the feeding conveyor belt, it promotes the end of the metal plate to fully abut against the positioning plate 18, ensuring the cutting accuracy. Then, through the further downward movement of the pushing plate 25, the two groups of clamping plates 23 rigidly clamp and fix the metal plate;

[0052] By rotating the torsion wheel to drive the screw rod 17 to rotate, combined with the slide bar to adjust the distance between the fixed table 12 and the movable table 13, and then adjust the position of the positioning plate 18, the precise cutting of metal plates with different lengths can be realized, and the distance between the two groups of clamping processing units 3 can be synchronously adjusted to realize the post-processing of the cutting surfaces at both ends of metal plates with different lengths;

[0053] While the metal plate is stably clamped in multiple directions, the auxiliary pressing plate 214 is synchronously elastically pressed on the metal plate. Combined with the limitation of the end of the metal plate by the positioning plate 18 on the top of the movable table 13, an all-round fixation is formed, effectively avoiding the shaking of the metal plate during the cutting process, ensuring the flatness of the cut surface, and improving the cutting quality.

[0054] Embodiment Two: Please refer to Figures 8 - 10 As shown, for the problem of the linked feeding of the cut metal plate and the precise and diversified post-processing of the cutting surface, the following solution can be adopted:

[0055] In this embodiment, an upper conveyor table 35 is arranged above the lower conveyor table 31. A third support plate is fixedly connected to the inside of the upper conveyor table 35, and three third rollers that are rotatably connected to both sides and above the third support plate. An upper discharge conveyor belt that slides with the third support plate is drivingly connected between the third rollers. The third support plate is used to increase the horizontal extrusion effect of the upper discharge conveyor belt on the metal plate. The arrangement of the three third rollers causes the upper discharge conveyor belt to be in a triangular structure, which is used to assist in increasing the convenience of the metal plate entering between the upper discharge conveyor belt and the lower discharge conveyor belt;

[0056] A multi-stage sleeve rod is installed between the upper conveying platform 35 and the U-shaped bracket 32 ​​to increase the stability of the upper conveying platform 35 when it is lifted and lowered, and an auxiliary spring 36 is located outside the multi-stage sleeve rod. The design of the upper conveying platform 35 and the lower conveying platform 31 combined with the auxiliary spring 36 ensures the stability of the cut metal plates of different sizes during the conveying process, which provides a good foundation for the subsequent deburring of the wire brush disc 33 and the grinding of the grinding disc 34.

[0057] The upper discharging conveyor belt and the lower discharging conveyor belt on the upper conveying platform 35 and the lower conveying platform 31 rotate in opposite directions at the same speed, and combined with the auxiliary spring 36, the upper discharging conveyor belt and the lower discharging conveyor belt clamp the metal sheet, so that the metal sheet is stably conveyed, and the wire brush disc 33 and the grinding disc 34 are driven to rotate by the corresponding motor. The cutting burrs on the cutting surface of the metal sheet are first removed by the wire brush disc 33, and then the saw marks on the cutting surface are polished by the grinding disc 34.

[0058] The pusher unit 4 includes a push rod 41 slidably connected to the bottom of the fixed platform 12, and the push rod 41 is connected to a push plate 43 that slides with the top of the fixed platform 12 through an L-shaped rod 42. A return spring 44 is fixedly connected between the L-shaped rod 42 and the fixed platform 12. The push rod 41 carries the L-shaped rod 42 to move the push plate 43, and compresses the return spring 44 to push the cut and split metal sheet to between the two sets of upper conveying platforms 35 and the lower conveying platform 31.

[0059] A support rod that slides with the fixed platform 12 is fixedly connected to the L-shaped rod 42 and inside the reset spring 44 to prevent the reset spring 44 from being compressed and bent, thereby reducing its service life. The end of the support rod is connected to a limiting block to further prevent the reciprocating saw 16 from moving during cutting, which would cause the rotating belt 46 to rotate.

[0060] The bottom of the fixed platform 12 is fixedly connected with a mounting seat 45, and the bottom of the mounting seat 45 is rotatably mounted with four groups of rotating wheels distributed in a right-angled trapezoid. The four groups of rotating wheels distributed in a right-angled trapezoid make the rotating belt 46 present a shape similar to a right-angled trapezoid after installation, and the rotating wheels are connected by the rotating belt 46. A connecting block 47 is connected between the rotating belt 46 and the pushing rod 41, and a linkage plate 48 is installed on the rotating belt 46 through a spring hinge.

[0061] During the process of the fixed seat 15 carrying the reciprocating saw 16 for moving cutting and contacting the linkage plate 48, and cooperating with the spring hinge, the linkage plate 48 is prompted to flip and separate from the fixed seat 15 and then reset. When the reciprocating saw 16 finishes cutting the metal sheet, the fixed seat 15 moves to the other side of the linkage plate 48. When the fixed seat 15 prompts the reciprocating saw 16 to perform a horizontal reverse reset movement, the fixed seat 15 contacts the linkage plate 48, and the flipping of the linkage plate 48 is restricted by the contact between one side of the linkage plate 48 and the rotating belt 46, thereby driving the rotating belt 46 to rotate. The rotating belt 46 combines with the connecting block 47 to drive the push rod 41 to carry the L-shaped rod 42 to prompt the push plate 43 to move;

[0062] Until the linkage plate 48 follows the rotating belt 46 and moves to the oblique side of the right trapezoid, the distance between the linkage plate 48 and the fixed seat 15 increases and they separate. Under the compressive elastic force of the return spring 44, the rotating belt 46 rotates in the reverse direction to reset, driving the push plate 43 to reset, so as to perform a feeding process for cutting the metal sheet;

[0063] The rotating belt 46 is in sliding contact with the mounting seat 45, which is used to ensure the contact effect during the movement of the fixed seat 15 carrying the linkage plate 48. The linkage plate 48 and the rotating belt 46 are arranged perpendicular to each other in an L shape. The spring hinge is installed at the right-angle position on one side of the linkage plate 48 and the rotating belt 46, so as to avoid the problem of the linkage plate 48 flipping during the reset movement of the reciprocating saw 16;

[0064] During the reset process of the electric sliding table 14 driving the reciprocating saw 16 to complete cutting, through the interaction with the linkage plate 48, the pushing unit 4 is automatically triggered to push the cut metal sheet into the space between the upper conveyor table 35 and the lower conveyor table 31, simplifying the operation process and improving the work efficiency.

[0065] Embodiment Three: Please refer to Figures 1 - 10 As shown, the present invention also proposes a cutting method for a metal cutting device in mechanical equipment processing, including the following steps:

[0066] Step One: The metal sheet is conveyed by the rotation of the feeding conveyor belt on the feeding table 1 until one end of the metal sheet abuts against the positioning plate 18 on the movable table 13. The electric push rod 26 drives the push plate 25 to move downward. The push plate 25 combines with the pressure spring 28 to prompt the pressure seat 21 to move downward and elastically squeeze against the top of the metal sheet, and the auxiliary pressure plate 214 above the fixed table 12 is synchronously elastically squeezed against the metal sheet;

[0067] Step 2: The pushing plate 25 continues to descend to compress the pressure spring 28. The sleeve 212 moves downward relative to the rotating rod 29. With the guidance of the spiral guiding groove 213 on the guiding pin 211, the rotating rod 29 drives the gear 210 to rotate. The gear 210 drives the L-shaped toothed plates 22 engaged on both sides to drive the clamping plates 23 to move relative to each other. Combining with the auxiliary balls rolling and embedded at the bottom of the clamping plates 23, the elastically extruded metal plate is positioned in the center. And combining with the rotation of the feeding conveyor belt, the end of the metal plate is fully flush with the positioning plate 18, ensuring the cutting accuracy. Then, through the further descending movement of the pushing plate 25, the two clamping plates 23 rigidly clamp and fix the metal plate;

[0068] Step 3: Rotate the screw 17 and adjust the distance between the fixed table 12 and the movable table 13 through the sliding rod, and then adjust the position of the positioning plate 18 to perform precise cutting of metal plates of different lengths. And synchronously adjust the distance between the two clamping processing units 3 to realize the post-processing of the cutting surfaces at both ends of metal plates of different lengths;

[0069] Step 4: The electric sliding table 14 drives the fixed seat 15 to carry the reciprocating cutting saw 16 to move. The reciprocating cutting saw 16 performs cutting processing on the metal plate stably clamped in multiple directions. And during the movement of the fixed seat 15, it contacts the linkage plate 48. Through the cooperation of the spring hinge, the linkage plate 48 flips and separates from the fixed seat 15 and then resets. After the reciprocating cutting saw 16 finishes cutting the metal plate, the fixed seat 15 moves to the other side of the linkage plate 48;

[0070] Step 5: When the electric sliding table 14 combines with the fixed seat 15 to make the reciprocating cutting saw 16 move horizontally and reverse to reset, the fixed seat 15 contacts the linkage plate 48. By restricting the flipping of the linkage plate 48 through the contact between one side of the linkage plate 48 and the rotating belt 46, the rotating belt 46 is driven to rotate. The rotating belt 46 combines with the connecting block 47 to drive the push rod 41 to carry the L-shaped rod 42 to move the pushing plate 43, and at the same time compress the reset spring 44, and push the cut and divided metal plate between the two upper conveying tables 35 and the lower conveying table 31. Until the linkage plate 48 moves to the oblique side of the right-angled trapezoid following the rotating belt 46, the linkage plate 48 is separated from the fixed seat 15. Under the compression elastic force of the reset spring 44, the rotating belt 46 reversely resets and rotates, driving the pushing plate 43 to reset;

[0071] Step 6: The upper discharge conveyor belt and the lower discharge conveyor belt on the upper conveying table 35 and the lower conveying table 31 rotate in the same speed and opposite directions, and combine with the auxiliary spring 36 to clamp the metal plate by the upper discharge conveyor belt and the lower discharge conveyor belt, so that the metal plate is stably conveyed. The two motors on the U-shaped bracket 32 drive the corresponding wire brush disks 33 and grinding disks 34 to rotate. First, the wire brush disk 33 removes the cutting burrs on the cutting surface of the metal plate, and then the grinding disk 34 grinds the cutting surface.

[0072] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
