Description

Technical Field

[0001] This utility model relates to the field of cutting protection technology, specifically a cutting device with a protective structure. Background Technology

[0002] In the process of parts processing, cutting equipment is an indispensable tool used to precisely cut workpieces.

[0003] The existing cutting setup mainly consists of a worktable, a lifting mechanism, and a cutting assembly. When cutting a workpiece, the workpiece is first placed on the worktable. Then, the pneumatic cylinder is activated, which drives the lifting block to move down. The lifting block drives the cutting blade to move down until the cutting blade contacts the surface of the workpiece. Then, the motor is activated, which causes the cutting blade to rotate. Through the high-speed rotation of the cutting blade, the workpiece can be cut.

[0004] Existing cutting equipment, due to the exposed cutting blade without a protective structure, poses a risk of injury to operators or other personnel who may accidentally touch the blade after cutting, especially when the equipment is idle. Furthermore, the exposed blade is susceptible to impact from external objects, leading to blade damage, and may also be affected by environmental factors such as dust and moisture, causing the blade to rust or corrode. Therefore, a cutting equipment with a protective structure is proposed to address these issues. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background, this utility model proposes a cutting device with a protective structure.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A cutting device with a protective structure, comprising a base, a fixed plate fixedly connected to the base, a groove formed on the fixed plate, a T-shaped slider slidably mounted within the groove, an L-shaped plate fixedly connected to one side wall of the T-shaped slider, and a protective mechanism provided on the L-shaped plate. The protective mechanism includes a fixed block, a fixed block fixedly connected to the L-shaped plate, first fixed seats mounted on both side walls of the fixed block, arc-shaped plates hinged within each of the two first fixed seats, protective plates fixedly connected to both side walls of each arc-shaped plate, a fixed column mounted on the top side of the fixed block, a sliding sleeve slidably mounted on the fixed column, second fixed seats fixedly connected to both side walls of the sliding sleeve, swing plates hinged within each of the two second fixed seats, and a third fixed seat hinged to the other end of each of the two swing plates, with the third fixed seat fixed to the outer side wall of the arc-shaped plate. When cutting parts... During cutting, the sliding sleeve moves upward along the fixed column, causing the swing plate to tilt upward as well. This increases the angle between the two swing plates, and the swing plate moves one end of the two arc-shaped plates and the protective plate away until the cutting blade is exposed. The sliding sleeve is then fixed in place by the locking bolts. This design ensures that the cutting blade can smoothly contact and cut the workpiece during cutting, while avoiding interference from the protective structure. After cutting is completed, when the equipment is idle, the sliding sleeve moves downward, causing the swing plate to tilt downward as well. This reduces the angle between the two swing plates, and the swing plate moves one end of the two arc-shaped plates and the protective plate closer together until the cutting blade is surrounded. The sliding sleeve is then fixed in place by the locking bolts. The combination of the arc-shaped plates and the protective plate provides all-around protection for the cutting blade, effectively preventing it from being impacted or damaged by external objects when idle, thus improving the safety of the equipment.

[0007] Preferably, the sliding sleeve has a screw hole, and a locking bolt is rotatably fitted in the screw hole. The end of the locking bolt abuts against the outer surface of the fixing column. When using the device, by setting the locking bolt, the sliding sleeve can be locked and fixed when the sliding sleeve is adjusted to the required position.

[0008] Preferably, a motor is installed on one side wall of the T-shaped slider, the output end of the motor is connected to a rotating shaft, a cutting blade is fitted onto the end of the rotating shaft, a pneumatic cylinder is installed on the top of the fixed plate, a pneumatic rod is fitted to the working end of the pneumatic cylinder, and the bottom end of the pneumatic rod is fixed to the T-shaped slider. A control panel is installed on the side wall of the fixed plate, and the control panel is used to control the start and stop of the motor and the pneumatic cylinder. During cutting, the pneumatic cylinder is started, causing the T-shaped slider to move the cutting blade downward. When the cutting blade moves down to contact the surface of the workpiece, the motor is started, causing the cutting blade to rotate, thereby enabling the workpiece to be cut.

[0009] Preferably, the base has a cutting groove, which is located directly below the cutting blade. When using the device, the cutting groove ensures that the cutting blade can be accurately positioned on the workpiece during cutting, avoiding cutting errors caused by blade offset.

[0010] The advantages of this utility model are:

[0011] 1. When cutting parts, the sliding sleeve moves upward along the fixed column, which in turn causes the swing plate to tilt and move upward, increasing the angle between the two swing plates. The swing plate drives one end of the two arc plates and the protective plate to gradually move away until the cutting blade is exposed. The sliding sleeve is fixed in the current position by the locking bolt. This design ensures that the cutting blade can smoothly contact and cut the workpiece during the cutting process, while avoiding interference from the protective structure to the cutting operation.

[0012] 2. After the cutting operation is completed, when the equipment is idle, the sliding sleeve moves down, which in turn causes the swing plate to tilt and move down as well. This reduces the angle between the two swing plates, and the swing plate drives one end of the two arc plates and the protective plate to gradually approach each other until they surround the cutting blade. The sliding sleeve is then fixed in its current position by locking bolts. Through the cooperation of the arc plates and the protective plate, the cutting blade can be protected in all directions, effectively preventing the cutting blade 7 from being impacted or damaged by external objects when idle, thus improving the safety of the equipment.

[0021] Please see Figure 1-5As shown, a cutting device with a protective structure includes a base 1, a fixing plate 2 fixedly connected to the base 1, a groove 3 formed on the fixing plate 2, a T-shaped slider 4 slidably mounted in the groove 3, an L-shaped plate 8 fixedly connected to one side wall of the T-shaped slider 4, and a protective mechanism provided on the L-shaped plate 8. The protective mechanism includes a fixing block 9, a fixing block 9 fixedly connected to the L-shaped plate 8, and first fixing seats 10 installed on both side walls of the fixing block 9. Arc-shaped plates 11 are hinged to both first fixing seats 10, and protective mechanisms are fixedly connected to both side walls of each arc-shaped plate 11. A fixing post 13 is installed on the top side of the plate 12 and the fixing block 9. A sliding sleeve 14 is slidably mounted on the fixing post 13. A second fixing seat 15 is fixedly connected to both side walls of the sliding sleeve 14. A swing plate 16 is hinged to each of the two second fixing seats 15. A third fixing seat 17 is hinged to the other end of each of the two swing plates 16. The third fixing seat 17 is fixed to the outer side wall of the arc plate 11. A screw hole is opened on the sliding sleeve 14. A locking bolt 18 is rotatably mounted in the screw hole, and the end of the locking bolt 18 abuts against the outer surface of the fixing post 13. During operation, when When cutting the parts, the sliding sleeve 14 moves upward along the fixed post 13, causing the swing plate 16 to also tilt and move upward, increasing the angle between the two swing plates 16. The swing plate 16 drives one end of the two arc-shaped plates 11 and the protective plate 12 to gradually move away until the cutting blade 7 is exposed. The sliding sleeve 14 is then fixed in its current position by the locking bolt 18. This design ensures that the cutting blade 7 can smoothly contact and cut the workpiece during the cutting process, while avoiding interference from the protective structure to the cutting operation. After the cutting operation is completed... When the equipment is idle, the sliding sleeve 14 moves down, which in turn causes the swing plate 16 to tilt and move down as well, making the included angle between the two swing plates 16 smaller. The swing plate 16 drives one end of the two arc plates 11 and the protective plate 12 to gradually approach each other until they surround the cutting blade 7. The sliding sleeve 14 is fixed in the current position by the action of the locking bolt 18. Through the cooperation of the arc plates 11 and the protective plate 12, the cutting blade 7 can be protected in all directions, effectively preventing the cutting blade 7 from being impacted or damaged by external objects when idle, thus improving the safety of the equipment.

[0022] Please see Figure 1-2 As shown, a motor 5 is installed on one side wall of the T-shaped slider 4. The output end of the motor 5 is connected to a rotating shaft 6. A cutting blade 7 is fitted onto the end of the rotating shaft 6. A pneumatic cylinder 19 is installed on the top of the fixed plate 2. A pneumatic rod is fitted to the working end of the pneumatic cylinder 19. The bottom end of the pneumatic rod is fixed to the T-shaped slider 4. A control panel 20 is installed on the side wall of the fixed plate 2. The control panel 20 is used to control the start and stop of the motor 5 and the pneumatic cylinder 19. During operation, when cutting, the pneumatic cylinder 19 is started, causing the pneumatic rod to push the T-shaped slider 4 downward. The T-shaped slider 4 drives the cutting blade 7 downward. When the cutting blade 7 moves down to contact the surface of the workpiece, the motor 5 is started, causing the cutting blade 7 to rotate, thereby enabling the workpiece to be cut.

[0023] The base 1 has a cutting groove 21, which is located directly below the cutting blade 7. When the device is in operation, the cutting groove 21 ensures that the cutting blade 7 can be accurately positioned on the workpiece during cutting, thus avoiding cutting errors caused by the offset of the cutting blade 7.

[0024] Working Principle: Existing cutting equipment exposes the cutting blade 7 without a protective structure. After cutting, especially when the equipment is idle, operators or other personnel are easily injured by accidental contact with the blade. Furthermore, the exposed blade 7 is susceptible to impact from external objects, leading to blade damage, and may also be affected by environmental factors such as dust and moisture, causing rust or corrosion. Therefore, this invention proposes a cutting device with a protective structure to address these issues. When cutting parts, the sliding sleeve 14 moves upward along the fixed column 13, causing the swing plate 16 to tilt upward as well, increasing the angle between the two swing plates 16. The swing plate 16 drives one end of the two arc-shaped plates 11 and the protective plate 12 to gradually move away until the cutting blade 7 is exposed. The locking bolt 18 then fixes the sliding sleeve 14 in its current position. This design ensures that the cutting blade 7 can be protected during the cutting process. The system smoothly contacts and cuts the workpiece while avoiding interference from the protective structure during the cutting operation. During cutting, the pneumatic cylinder 19 is activated, causing the pneumatic rod to push the T-shaped slider 4 downward. The T-shaped slider 4 drives the cutting blade 7 downward. When the cutting blade 7 reaches contact with the workpiece surface, the motor 5 is activated, causing the cutting blade 7 to rotate, thus enabling the cutting of the workpiece. After the cutting operation is completed, when the equipment is idle, the sliding sleeve 14 is moved downward, causing the swing plate 16 to tilt and move downward as well, reducing the angle between the two swing plates 16. The swing plate 16 drives one end of the two arc plates 11 and the protective plate 12 to gradually approach each other until they surround the cutting blade 7. The sliding sleeve 14 is fixed in its current position by the locking bolt 18. Through the cooperation of the arc plates 11 and the protective plate 12, the cutting blade 7 can be protected in all directions, effectively preventing the cutting blade 7 from being impacted or damaged by external objects when idle, thus improving the safety of the equipment.
