Description

Technical Field

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

[0002] In fields such as machinery manufacturing, auto parts, and hardware processing, metal sheet cutting is an indispensable step, and its processing precision and efficiency directly affect the quality of subsequent products and production schedules. With the development of the industry, various cutting devices have emerged, providing diverse solutions for metal sheet processing.

[0003] Currently, most metal sheet cutting equipment on the market is large-scale. While this type of equipment can meet the processing needs of large and thick metal sheets, it presents significant inconveniences when dealing with smaller metal sheets. Large equipment has a wide operating platform and a complex positioning system. For smaller metal sheets, it often requires cumbersome fixing procedures, and slight oversights can lead to positioning deviations, affecting cutting accuracy. Furthermore, the startup and debugging process for large equipment is lengthy. For processing small batches of small-sized metal sheets, this results in excessive idle time, leading to low production efficiency and increased unit processing costs.

[0004] Furthermore, large equipment occupies a significant area and lacks mobility, making it difficult to deploy flexibly in small processing workshops or environments with limited space, further restricting its applicability to processing small metal sheets. Therefore, developing a dedicated cutting device suitable for processing smaller metal sheets has become an urgent need to solve the current processing inconvenience problem. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a cutting device for metal plate processing, which solves the technical problem that although such equipment in the prior art can meet the processing needs of large-size and thick metal plates, it has obvious inconvenience when dealing with smaller metal plates.

[0006] According to one aspect, at least one embodiment of the present disclosure provides a cutting apparatus for metal sheet processing, comprising:

[0007] The housing and a pair of feed frames are both located outside the housing;

[0008] A supporting feeding assembly is disposed between the feeding outer frame and the outer shell;

[0009] A cutting assembly disposed within the housing;

[0010] The cutting assembly includes an inlet, which is located on both sides of the housing. A horizontal opening is provided on the side surface of the housing. A movable frame is provided at the bottom of the housing. The movable frame is connected to the bottom of the housing via a linear drive. A cutting motor is mounted on the movable frame, and a drive gear is provided at the output end of the cutting motor.

[0011] As a further technical solution, the movable frame is located in the horizontal opening, and a pair of telescopic cylinders are provided on the top of the outer shell. The output end of the telescopic cylinder is located inside the outer shell, and a clamping frame is provided at the output end of the telescopic cylinder.

[0012] As a further technical solution, an exhaust port and an air inlet are respectively opened on both sides of the outer shell, the bottom of the outer shell is an inclined structural surface, the clamping frame is located above the saw blade part of the cutting motor, and the cross-section of the clamping frame is U-shaped.

[0013] As a further technical solution, the supporting feeding assembly includes a pair of fixed frames, each fixed to both ends of the outer shell surface, with an adjusting screw rotatably connected between the fixed frames and a guide rod fixedly connected between the fixed frames.

[0014] As a further technical solution, a pair of the feeding outer frames are respectively slidably connected to both ends of the guide rod. The feeding outer frame is connected to the adjusting screw through a threaded connection.

[0031] like Figures 1-3 As shown, a cutting apparatus for metal sheet processing according to an embodiment of the present disclosure is illustrated, comprising:

[0032] The outer casing 1 and a pair of feeding frames 2 are both disposed outside the outer casing 1;

[0033] A supporting feeding assembly 4 is provided, which is disposed between the feeding outer frame 2 and the outer shell 1;

[0034] Cutting component 3, wherein the cutting component 3 is disposed in the housing 1;

[0035] The cutting assembly 3 includes an inlet 3-1, which is located on both sides of the outer casing 1. A horizontal opening 3-2 is provided on the side surface of the outer casing 1. A movable frame 3-3 is provided at the bottom of the outer casing 1. The movable frame 3-3 is connected to the bottom of the outer casing 1 by a linear drive. A cutting motor 3-4 is mounted on the movable frame 3-3. A drive gear 3-5 is provided at the output end of the cutting motor 3-4. The movable frame 3-3 is located in the horizontal opening 3-2. A pair of telescopic cylinders 3-6 are provided at the top of the outer casing 1. The output end of the telescopic cylinders 3-6 is located inside the outer casing 1. A clamping frame 3-7 is provided at the output end of the telescopic cylinders 3-6. An outlet 3-8 and an air inlet 3-9 are respectively provided on the two side surfaces of the outer casing 1. The bottom of the outer casing 1 is an inclined structural surface. The clamping frame 3-7 is located above the saw blade part of the cutting motor 3-4. The cross-section of the clamping frame 3-7 is U-shaped.

[0036] In some examples, a cutting assembly 3 is designed to achieve protective cutting and waste collection. This assembly includes symmetrically distributed inlets 3-1 on both sides of the outer casing 1, providing channels for the metal plate to enter and exit. A horizontal opening 3-2 on the side surface is opened horizontally and adapted to a movable frame 3-3 at the bottom. The movable frame 3-3 is slidably connected to the bottom of the outer casing 1 via a slide rail and is driven by a linear drive device (such as a servo motor), allowing it to move horizontally along the horizontal opening 3-2. A cutting motor 3-4 on the frame is fixed with bolts, and the drive gear 3-5 at the output end meshes with the gear at the shaft end of the saw blade portion of the cutting motor 3-4, driving the saw blade to rotate. A telescopic cylinder 3-6 on the top of the outer casing 1 is vertically installed, and the cylinder body is fixed by a flange. A clamping frame 3-7 at the output end is located directly above the saw blade portion of the cutting motor 3-4, with a U-shaped cross-section and its inner side fitting against the edge of the metal plate. Exhaust ports 3-8 and air inlets 3-9 on both sides of the outer casing 1 are located on either side of the saw blade portion of the cutting motor 3-4, and the inclined structure at the bottom is inclined towards the exhaust port 3-8.

[0037] During operation, the metal plate enters the outer casing 1 through the inlet 3-1. The telescopic cylinder 3-6 drives the clamping frame 3-7 to descend. The U-shaped structure wraps around and clamps the edge of the metal plate, preventing it from shaking during cutting. The cutting motor 3-4 starts, driving the saw blade part of the cutting motor 3-4 to rotate. The linear drive device moves the moving frame 3-3 along the cross opening 3-2, and the saw blade cuts the metal plate. During the cutting process, the outer casing 1 forms a closed space, preventing debris from splashing. Airflow enters through the air inlet 3-9, blowing the debris towards the bottom inclined surface. The debris slides along the inclined surface to the outlet 3-8 and is discharged, achieving waste collection. The cross opening 3-2 provides a moving path for the moving frame 3-3, the linear drive device ensures a straight cutting path, and the U-shaped clamping frame 3-7 enhances the fixing effect on the metal plate, preventing the edges from lifting. This component combines closed cutting with directional airflow to achieve safe cutting and centralized waste collection, improving operational safety and cleanliness.

[0038] like Figures 1-3 As shown in the figure, the supporting feeding assembly 4 in this embodiment includes a pair of fixed frames 4-1, each fixed at both ends of the surface of the outer shell 1. An adjusting screw 4-2 is rotatably connected between the fixed frames 4-1, and a guide rod 4-3 is fixedly connected between the fixed frames 4-1. A pair of feeding outer frames 2 are slidably fitted to both ends of the guide rod 4-3. The feeding outer frames 2 are connected to the adjusting screw 4-2 by a threaded connection. Each feeding outer frame 2 has a support column 4-4 at its bottom, and a pulley 4-5 is provided at the lower end of the support column 4-4.

[0039] In some examples, a supporting feeding assembly 4 is designed to achieve the adaptive feeding of metal plates. This assembly includes symmetrically distributed fixing frames 4-1 at both ends of the surface of the outer shell 1, which are fixed by welding. The two ends of the adjusting screw 4-2 are rotatably connected between the fixing frames 4-1 through bearings. The surface of the screw body is provided with bidirectional threads. The guide rod 4-3 is parallel to the adjusting screw 4-2 and is fixed to the fixing frames 4-1 at both ends by welding. The feeding outer frame 2 is slidably fitted onto the two ends of the guide rod 4-3 through a sliding sleeve. The bottom of the outer frame 2 is engaged with the adjusting screw 4-2 with threads of different directions to form a counter-moving structure. The support column 4-4 at the bottom of the feeding outer frame 2 is vertically welded, and the pulley 4-5 at the lower end is fixed by a bracket and can roll along the ground.

[0040] During operation, the adjusting screw 4-2 is rotated according to the width of the metal plate. Under the action of the bidirectional thread, the two feeding frames 2 move in opposite directions along the guide rod 4-3, adjusting the spacing to match the width of the metal plate. The metal plate is placed on the feeding frame 2 and conveyed into the outer shell 1 with the support of the feeding frame 2. The pulley 4-5 reduces friction during the movement of the feeding frame 2, facilitating position adjustment. The guide rod 4-3 ensures smooth movement of the feeding frame 2, preventing deviation. The bidirectional thread allows the two feeding frames 2 to move synchronously in opposite directions, ensuring that the metal plate is always conveyed in the center. The support column 4-4 raises the height of the feeding frame 2, keeping it level with the inlet 3-1 of the outer shell 1, ensuring smooth conveying. The pulley 4-5 allows the feeding frame 2 to move slightly with the conveying of the metal plate, reducing the pulling on the metal plate and maintaining stability during cutting. This component, through the combination of width adjustment and rolling support, achieves stable conveying of metal plates of different widths, providing a precise feed reference for cutting.

[0041] For example, such as Figure 1 As shown, the feed frame 2 has an L-shaped cross-section, and the adjusting screw 4-2 has a double-segment thread structure with opposite thread directions at both ends.

[0042] In some examples, the feed frame 2 has an L-shaped cross-section, supporting the metal plate from the bottom and sides. The bottom supports the plate to prevent it from falling, while the sides limit its movement to avoid deviation. The adjusting screw 4-2 has a double-stage reverse thread, which drives the two outer frames to move synchronously in opposite directions when rotated, ensuring symmetrical spacing adjustment and keeping the plate always centered during feeding. This adapts to plates of different widths, improves feeding stability, and lays the foundation for cutting accuracy.

[0043] For example, such as Figure 2 As shown, one end of the adjusting screw 4-2 is provided with a crank handle 5.

[0044] In some examples, the crank handle 5 at one end of the adjusting screw 4-2 facilitates manual adjustment. Turning the handle rotates the screw, requiring no additional tools and making operation simple and labor-saving. The handle allows for precise control of the outer frame's movement distance, quickly adapting to the width of the metal sheet. This is especially suitable for processing small batches of multi-specification sheet materials, improving adjustment efficiency, ensuring the accurate positioning of the feeding outer frame 2, and guaranteeing cutting quality.

[0045] For example, such as Figure 3 As shown, ramps 6 are provided at both ends of the bottom of the outer shell 1.

[0046] In some examples, the ramp 6 at the bottom inside the housing 1 guides cutting debris to gather towards the central inclined surface. The ramps 6 at both ends connect with the bottom inclined surface to prevent debris from accumulating in corners. Combined with the airflow from the air inlets 3-9, this allows the debris to slide more smoothly towards the outlets 3-8, improving waste collection efficiency, reducing cleaning dead corners inside the housing 1, maintaining a clean cutting environment, and reducing equipment maintenance frequency.

[0047] In practical use: Based on the width of the metal sheet, turn the rocker handle 5 to adjust the screw 4-2, causing the feeding frame 2 to move in opposite directions along the guide rod 4-3. The pulley 4-5 assists in adjusting to the appropriate width. The metal sheet is placed on the L-shaped feeding frame 2 and pushed to the inlet 3-1 of the outer casing 1. The telescopic cylinder 3-6 drives the U-shaped clamping frame 3-7 to descend, fitting snugly against the edge of the metal sheet. The cutting motor 3-4 starts, driving the saw blade to rotate via the drive gear 3-5. The moving frame 3-3 moves horizontally along the cross opening 3-2 to complete the cutting. Airflow is blown in through the air inlet 3-9, guiding the debris through the bottom inclined surface and the ramp 6 to the outlet 3-8. After cutting, the clamping frame 3-7 rises, and the metal sheet is sent out from the other inlet 3-1. This process is suitable for processing small sheet metal, offering convenient and efficient operation.
