Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of sheet metal cutting and processing, and specifically to a CNC sheet metal cutting device. Background Technology

[0002] In modern manufacturing, sheet metal cutting is a fundamental process in industries such as metal processing, furniture manufacturing, and building decoration, directly affecting the accuracy of subsequent processing and product quality. As industrial production demands higher efficiency and precision, CNC cutting equipment, with its high degree of automation and stable cutting accuracy, has gradually replaced traditional manual cutting, becoming the mainstream equipment.

[0003] However, existing CNC cutting equipment has significant limitations when processing specific sheet materials, with the inability to cut from both sides simultaneously being a prominent issue. Traditional equipment often employs a single cutting head design. When processing sheet materials requiring symmetrical cutting from both sides, one side must be cut first, followed by manual flipping of the sheet material or adjustment of the cutting head position before processing the other side. This step-by-step operation not only increases the complexity of the process but is also prone to errors due to secondary positioning, resulting in inconsistent cutting dimensions on both sides and affecting product assembly accuracy.

[0004] For thick or rigid sheets, manual flipping is difficult and poses safety hazards, further reducing production efficiency. Meanwhile, step-by-step cutting extends the processing cycle of a single sheet, making it difficult to meet the demands of mass production and hindering capacity expansion. Therefore, developing a CNC device capable of simultaneous cutting from both sides has become a key direction for solving these problems and optimizing the production process. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a CNC cutting device for sheet metal, which solves the technical problem that the prior art can only perform single cutting and cannot simultaneously cut both sides of the sheet metal.

The drive rollers are all driven to rotate by electricity, and the drive rollers are respectively located above the rectangular opening and the elongated opening.

[0015] As a further technical solution, the cutting assembly includes a pair of cylinders, which are vertically installed at both ends of the top of the gantry frame.

[0016] As a further technical solution, a telescopic cover is connected between the outer frame and the outer groove, and a protective cover is provided at the bottom of the outer frame.

[0017] As a further technical solution, a stabilizing pressure roller is rotatably connected to the surface of the equipment frame, and the stabilizing pressure roller is close to a pair of cutting saw blades.

[0032] like Figures 1-3 As shown, it illustrates a CNC cutting device for sheet metal according to an embodiment of the present disclosure, comprising:

[0033] The equipment frame 1 and a pair of outer grooves 2 are provided on both sides of the equipment frame 1;

[0034] A conveying and propulsion assembly 5 is mounted on the equipment frame 1;

[0035] Side cutting assembly 4, which is disposed in the equipment frame 1 and the outer groove 2;

[0036] A gantry frame 3 and a cutting assembly 6 are provided, wherein the gantry frame 3 is fixed on the equipment frame 1, and the cutting assembly 6 is disposed on the equipment frame 1 and the gantry frame 3;

[0037] The side cutting assembly 4 includes a pair of outer frames 4-1, each of which is disposed in the outer groove 2. A pair of connecting rods 4-2 are provided on the side end face of each outer frame 4-1. One end of each connecting rod 4-2 is movably fitted into the outer groove 2. A cutting motor 4-3 is installed at the bottom of each outer frame 4-1. A cutting saw blade 4-4 is provided at the output end of the cutting motor 4-3. The cutting saw blade 4-4 is located in the outer frame 4-1. A base frame 4-5 is provided at the bottom of the equipment frame 1. A pair of screws 4-6 are rotatably connected in the base frame 4-5. The screws 4-6 are connected by transmission. A transmission gear 4-7 is provided at the transmission connection between the screws 4-6. A drive gear 4-8 is provided on one side of the base frame 4-5 and rotates by electric power. The drive gear 4-8 meshes with the transmission gear 4-7.

[0038] In some examples, to achieve synchronous cutting of both sides of the board, a side cutting assembly 4 is designed. This assembly includes outer grooves 2 on both sides of the equipment frame 1, which are opened on both sides of the board's movement direction. The threaded block at the bottom of the outer frame 4-1 is threadedly engaged with the screw 4-6 inside the base frame 4-5. The connecting rod 4-2 on the side end face of the outer frame 4-1 extends horizontally and is movably fitted into the sliding sleeve inside the outer groove 2, allowing it to slide along the length of the outer groove 2 to ensure smooth movement of the outer frame 4-1. The cutting motor 4-3 at the bottom of the outer frame 4-1 is fixed with bolts, and the cutting saw blade 4-4 at the output end is connected by a coupling. The edge of the saw blade protrudes from the inside of the outer frame 4-1 and can contact the side of the board. The screw 4-6 inside the base frame 4-5 is connected in parallel rotation via bearings, and the transmission gears 4-7 at one end of the rod mesh with each other to achieve synchronous counter-rotation of the two screws 4-6. The drive gear 4-8 on one side of the base frame 4-5 is driven by a motor and meshes with the transmission gear 4-7 therein to form a power transmission.

[0039] During operation, the motor drives the drive gear 4-8 to rotate, which in turn drives the two screws 4-6 to rotate synchronously via the transmission gear 4-7. The outer frame 4-1, under threaded engagement, moves along the outer groove 2 in opposite directions to adjust its distance from the side of the sheet material. The cutting motor 4-3 starts, driving the cutting saw blade 4-4 to rotate at high speed. During sheet material transport, both saw blades simultaneously contact the side of the sheet material, achieving synchronous cutting. The connection rod 4-2, in conjunction with the sliding sleeve, restricts the rotational freedom of the outer frame 4-1, ensuring stable cutting direction of the saw blade. The synchronous transmission of the screws 4-6 ensures that the moving distance of the outer frames 4-1 on both sides is consistent, resulting in the same cutting width on both sides of the sheet material. The cutting saw blade 4-4 is located within the outer frame 4-1, reducing the area of ​​flying cutting debris. This assembly, through the combination of synchronous transmission and stable support, achieves synchronous and precise cutting of both sides of the sheet material, improving processing efficiency and dimensional consistency.

[0040] like Figures 1-3As shown in the figure, the conveying and propulsion assembly 5 in this embodiment includes a rectangular opening 5-1 and a long opening 5-2. Both the rectangular opening 5-1 and the long opening 5-2 are opened on the surface of the equipment frame 1. The rectangular opening 5-1 and the long opening 5-2 are located on both sides of the outer groove 2. Several support rollers 5-3 are rotatably connected inside the rectangular opening 5-1 and the long opening 5-2. The upper end surface of the support rollers 5-3 is slightly higher than the surface of the equipment frame 1. A pair of drive rollers 5-4 are rotatably connected to the surface of the equipment frame 1. The drive rollers 5-4 are driven to rotate by electricity. The drive rollers 5-4 are respectively located above the rectangular opening 5-1 and the long opening 5-2.

[0041] In some examples, to achieve stable conveying and precise positioning of the sheet material, a conveying and propulsion assembly 5 is designed. This assembly includes rectangular openings 5-1 and elongated openings 5-2 on the surface of the equipment frame 1, located on both sides of the outer groove 2. Internal support rollers 5-3 are horizontally rotatable and evenly distributed along the conveying direction via bearings. The upper surface of the rollers is higher than the surface of the equipment frame 1, forming a support plane for the sheet material and reducing friction between the sheet material and the equipment frame 1. Drive rollers 5-4 on the surface of the equipment frame 1 are rotatably connected via bearings, located above the rectangular openings 5-1 and elongated openings 5-2, and driven by an independent motor. The surface of the rollers is covered with a rubber anti-slip layer, corresponding vertically to the support rollers 5-3 to form a clamping structure.

[0042] During operation, the sheet material is placed on support roller 5-3, which rotates to support the sheet material and reduce conveying resistance. Drive roller 5-4 rotates under the drive of a motor, its rubber anti-slip layer contacting the upper surface of the sheet material. Friction propels the sheet material forward, while the weight of drive roller 5-4 itself or the pressure applied by an adjustable pressure device ensures the sheet material adheres tightly to support roller 5-3, preventing slippage or deviation during conveying. The raised design of support roller 5-3 prevents direct contact between the sheet material and the surface of the equipment frame 1, reducing the risk of scratches. The upper and lower cooperation of drive roller 5-4 and support roller 5-3 forms multi-point clamping, ensuring the sheet material maintains horizontal and linear movement during conveying, providing a stable feed reference for edge cutting and slitting. This assembly, through the combination of rolling support and pressure drive, achieves stable conveying and precise positioning of the sheet material, ensuring the accuracy of subsequent cutting processes.

[0043] like Figures 1-3 As shown in the figure, the cutting assembly 6 in this embodiment includes a pair of cylinders 6-1, which are vertically installed at both ends of the top of the gantry frame 3. The output end of the cylinder 6-1 is connected to a cutting blade holder 6-2. A pressure strip 6-3 is provided between the gantry frames 3. A clamping hole 6-4 is provided on the upper surface of the pressure strip 6-3, and the cutting blade holder 6-2 is located in the clamping hole 6-4.

[0044] In some examples, a cutting assembly 6 is designed to achieve stable cutting of the sheet metal. This assembly includes cylinders 6-1 at both ends of the top of the gantry frame 3, which are vertically fixed by flanges. The output end is welded to the top center of the cutting blade holder 6-2. The cutting blade at the bottom of the blade holder is fixed by bolts, with the blade pointing vertically downwards. The pressure strip 6-3 on the inner side of the gantry frame 3 is horizontally fixed by a bracket and is located below the cutting blade holder 6-2. The clamping hole 6-4 on the upper surface corresponds to the position of the cutting blade holder 6-2, and the hole diameter is slightly larger than the width of the blade holder. The blade holder can move vertically along the clamping hole 6-4.

[0045] During operation, the sheet metal is conveyed to the cutting position. Cylinder 6-1 drives the cutting blade holder 6-2 to move downwards. The pressure bar 6-3 first contacts the upper surface of the sheet metal, pressing it firmly against the surface of the equipment frame 1. The blade holder continues to move downwards along the clamping hole 6-4, where the cutting blade contacts the sheet metal and applies vertical pressure, cutting the sheet metal. After cutting, cylinder 6-1 retracts, causing the blade holder to rise, facilitating subsequent sheet metal conveying. The clamping hole 6-4 guides the blade holder, ensuring a vertical cutting direction and preventing blade deviation that could lead to a skewed cut. The pressure bar 6-3 prevents the sheet metal from warping or moving during cutting due to force, ensuring a clean cut. Cylinder 6-1 provides a stable vertical driving force, ensuring the blade can cut the sheet metal quickly and neatly. This assembly combines pressure fixing with vertical cutting to achieve stable sheet metal cutting, improving cut quality and efficiency.

[0046] For example, such as Figure 1 As shown, a telescopic cover 7 is connected between the outer frame 4-1 and the outer groove 2, and a protective cover 8 is provided at the bottom of the outer frame 4-1.

[0047] In some examples, the telescopic cover 7 between the outer frame 4-1 and the outer slot 2 can move and extend with the outer frame 4-1, blocking the opening of the outer slot 2 and preventing cutting debris from entering the interior of the outer slot 2. The protective cover 8 at the bottom of the outer frame 4-1 covers the area below the cutting saw blade 4-4, further preventing debris from flying and protecting the operator's safety. Together, these features reduce the contamination and damage of equipment components by debris, while also making the working environment cleaner.

[0048] For example, such as Figure 1 As shown, a stabilizing pressure roller 9 is rotatably connected to the surface of the equipment frame 1, and the stabilizing pressure roller 9 is close to a pair of cutting saw blades 4-4.

[0049] In some examples, the stabilizing pressure roller 9 is positioned close to the cutting saw blade 4-4 to press the sheet metal down from above during cutting. It works in conjunction with the support roller 5-3 to prevent vibration or shifting of the sheet metal during cutting, ensuring a smooth cut edge. The rotating design of the stabilizing pressure roller 9 does not affect the sheet metal feeding process, improving stability and accuracy during cutting.

[0050] For example, such as Figure 2As shown, both the drive gear 4-8 and the transmission gear 4-7 are bevel gears, and the threads of the pair of screws 4-6 are opposite.

[0051] In some examples, the drive gear 4-8 and transmission gear 4-7 are bevel gears, which can change the transmission direction, converting the horizontal rotation of the drive gear 4-8 into the vertical rotation of the screw 4-6. The screws 4-6 have opposite thread directions, causing the outer frames 4-1 on both sides to move synchronously in opposite directions when the screws 4-6 rotate, ensuring that the cutting width on both sides of the sheet metal is consistent and improving the accuracy of synchronous adjustment.

[0052] In actual use: The sheet metal is placed on the support roller 5-3, and the drive roller 5-4 rotates to transport the sheet metal forward. The stabilizing pressure roller 9 provides auxiliary fixation from above. Based on the sheet metal width, the drive gear 4-8 drives the screw 4-6 to rotate via the transmission gear 4-7. The outer frame 4-1 moves along the outer groove 2 to adjust the position of the cutting saw blade 4-4. The cutting motor 4-3 drives the saw blade to rotate, simultaneously cutting both sides of the sheet metal. The cut sheet metal continues to be transported to the gantry frame 3. The cylinder 6-1 pushes the cutting blade holder 6-2 down, the pressure bar 6-3 first presses the sheet metal, and the cutting blade cuts the sheet metal along the clamping hole 6-4. The telescopic cover 7 and the protective cover 8 block debris. The entire process achieves double-sided cutting and continuous cutting operation without the need for manual flipping or adjustment.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
