Description

Technical Field

[0001] This invention relates to the field of metal sheet cutting technology, specifically a safe cutting device for metal sheet processing. Background Technology

[0002] Patent application CN220112432U includes a support column and a drive motor. The support column has a positioning through hole, and a protective frame is installed at its top. The protective frame has an adjustment groove on its edge. Support side plates are provided on the outer surface of the top of the support column, and support rods are installed between the side plates. The support rods pass through a connecting block, which is installed on the center surface of the drive motor. The output end of the drive motor passes through the adjustment groove, and a cutting blade is fixedly installed at the output end. This metal plate cutting device can protect the cutting blades by using the protective frame, preventing them from being exposed and improving safety during the cutting process. Simultaneously, the cutting blades can slide inside the protective frame, allowing for sliding and shifting cutting of the cover plate, facilitating the cutting of larger cover plates.

[0003] In the aforementioned patents, some of the existing equipment uses handheld cutting devices or simple fixed cutting machines when cutting metal sheets. During the cutting process, the sheet metal is prone to vibration, jumping, or even warping due to uneven force and insecure fixing. This not only seriously affects the cutting accuracy and cut quality but also poses a serious threat to the personal safety of the operators. The saw blade may lift the sheet metal during high-speed rotation, causing equipment damage or personal injury. When it is necessary to adjust the position of the cutting line or cut sheets of different widths, tedious manual adjustment and repositioning are often required. Summary of the Invention

[0016] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0017] (1) A cutting mechanism, a placement mechanism, an adjustment mechanism and a fixing mechanism are set above the fixed table. Through the pressing component and the pushing component, dynamic pressing and stable feeding of metal plates are realized during the cutting process. During the cutting process, when the metal plate is pushed by the push rod to the rotating circular saw cutting device, it will pass through the rotating wheel of the fixing mechanism and the squeezing wheel of the cutting mechanism. These two components constitute a progressive and flexible pressing system. The metal plate first lifts the rotating wheel. Under the damping action of the second spring, the rotating wheel applies a downward pressure to the plate, realizing the initial positioning and vibration suppression. Then, the plate enters the core cutting area, and its surface will push up the squeezing wheel under the sliding shell. At this time, the first spring is compressed, and the generated elastic force is finally transmitted to the squeezing wheel through the sliding shell and the fixing block, so that it is pressed tightly against the surface of the plate. This "floating" pressing method can adapt to plates of different thicknesses, ensuring that uniform and sufficient positive pressure can be obtained regardless of the slight unevenness or thickness tolerance of the plate. This effectively eliminates the risk of the board jumping, warping, or even being lifted by the saw blade during cutting, fundamentally ensuring the safety of the operator. The pressure roller applies pressure in front of the circular saw cutting equipment, which is equivalent to establishing a stable support point and damping point at the entry of the cutting point. It works together with the push rod behind to "clamp" the board in a stable mechanical state for feeding. This makes the movement trajectory of the board strictly constrained when it passes through the saw blade, effectively resisting the lateral force brought by the rotation of the saw blade, thereby improving the cutting quality.

[0018] (2) Through the cutting mechanism, placement mechanism and adjustment mechanism, it can quickly adapt to different cutting tasks and plate specifications, improving the versatility and working efficiency of the equipment. When it is necessary to adjust the position of the cutting line, it is only necessary to start the drive device on the first fixed long plate and the side of the connecting shell to drive the cutting head and the sliding long plate to move synchronously. The motor drives the threaded rod to rotate, and through the cooperation with the second threaded groove on the fixed slider, it drives the entire sliding frame and the circular saw cutting equipment installed under it to move laterally. At the same time, the drive device on the side of the connecting shell drives the sliding long plate to move laterally in complete synchronization through the cooperation of the threaded rod with the third threaded groove on the connecting block. This design ensures that the "blade groove" on the sliding long plate is always accurately aligned with the saw blade of the circular saw cutting equipment. No matter where the cutting head moves, the saw blade can pass smoothly through the groove without interfering with the platform. This avoids the trouble of manually and repeatedly setting the blade. The system eliminates the risk of damaging the saw blade or platform due to inaccurate tool setting. The adjustment process is completed with a single click, making it efficient and reliable. Furthermore, the adjustment mechanism provides another layer of flexibility for processing narrow plates. By rotating the handle, the screw drives the second fixed long plate and support plate to retract inward, forming an adjustable-width support platform. This allows the device to handle not only large-sized plates but also to stably support and transport narrow pieces, preventing them from falling or getting stuck during the pushing process due to insufficient support. The push rod is connected to the sliding long rod via a T-shaped slider and the sliding long groove on the sliding long plate, allowing it to adapt to the movement of the sliding long plate and change position, always maintaining an effective position for pushing the plate. This greatly reduces production preparation time and enables rapid switching between different cutting tasks. It is suitable for standardized mass production as well as flexibly responding to the personalized processing needs of multiple varieties and small batches. Attached Figure Description

[0043] A rotating handle 541 is fixedly connected to one end of the screw 54 away from the cutting mechanism 2, and a rotating block 542 is fixedly connected to the other end of the screw 54. The rotating block 542 is rotatably connected to one side of the supporting main rod 12.

[0044] The working principle of this invention is as follows: When cutting a metal plate, the metal plate is placed above the placement frame 41, with one side of the metal plate abutting against the push rod 146. During cutting, the circular saw cutting device 244 operates, and the drive motor on the drive device 3 on one side of the fixed table 1 drives the threaded rod to rotate. The threaded rod drives the sliding long rod 141 to move in the mounting groove 13 through the first threaded groove 143. The sliding long rod 141 drives the push rod 146 to push the metal plate through the T-shaped slider 148. The push rod 146 pushes the metal plate toward the circular saw cutting device 244. When the metal plate comes into contact with the circular saw on the circular saw cutting device 244, it is cut by the circular saw.

[0045] During the process of the push rod 146 pushing the metal plate towards the circular saw cutting device 244, the metal plate passes under the fixed component 62. When the metal plate passes under the rotating wheel 621, the metal plate squeezes the rotating wheel 621 and moves it upward. The rotating wheel 621 drives the sliding block 623 to slide in the connecting groove 612 through the connecting rod 622. The rotating wheel 621 squeezes and fixes the metal plate. When the metal plate is pushed by the push rod 146, the metal plate drives the rotating wheel 621 to rotate. When the metal plate passes under the extrusion wheel 259, the metal plate contacts the bottom of the extrusion wheel 259, pushing the extrusion wheel 259 to drive the fixed block 257 and the sliding shell 254 to move upward. The sliding shell 254 moves upward, and the bottom of the sliding cavity 256 squeezes the first spring 253 under the fixed plate 251. The metal plate passes under the extrusion wheel 259 and drives the extrusion wheel 259 to rotate. The extrusion wheel 259 presses the metal plate on the sliding long plate 45, increasing the stability of the metal plate during cutting.

[0046] When the cutting position needs to be adjusted, the drive motor on the drive device 3 on one side of the first fixed long plate 21 works. The drive motor drives the fixed slider 242 and the sliding frame 241 to move on the first fixed long plate 21 through the threaded rod and the second threaded groove 243. The sliding frame 241 drives the circular saw cutting device 244 to move. At this time, the drive motor on the drive device 3 on the side of the connecting shell 43 drives the connecting block 46 to move inside the connecting shell 43 through the threaded rod and the third threaded groove 461. The connecting block 46 drives the sliding long plate 45 to move through the sliding connecting block 451, so that the through groove on the sliding long plate 45 is always aligned with the circular saw on the circular saw cutting device 244. When the connecting assembly 24 moves, the fixed plate 251, the sliding shell 254, the fixed block 257 and the extrusion wheel 259 move with the connecting assembly 24 through the installation horizontal plate 245, so that the extrusion wheel 259 is always above the sliding long plate 45.

[0047] When cutting a narrower metal plate, rotate the handle 541. Rotating the handle 541 drives the screw 54 to rotate. The screw 54 drives the second fixed long plate 51 to move towards the placement frame 41 through the fourth threaded groove 511. The second fixed long plate 51 drives the round rod 52 to move. The round rod 52 drives the support plate 53 to move. At this time, the distance between the two support plates 53 becomes smaller. The metal plate is placed on the two support plates 53 on both sides. The push rod 146 pushes the metal plate to move under the extrusion wheel 259. Then it passes under the circular saw cutting device 244. The circular saw cutting device 244 cuts the metal plate. When the sliding long plate 45 moves, the sliding long grooves on both sides of the sliding long plate 45 cooperate with the connecting slider 147 to drive the push rod to move above the sliding long rod 141. The push rod 146 drives the T-shaped slider 148 to slide in the limiting slide groove 142. The push rod 146 changes position as the sliding long plate 45 moves.
