Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a metal cutting device that facilitates the removal of debris. Background Technology

[0002] Cutting is one of the commonly used metal processing methods. Rod-shaped metals are generally cut by turning. During cutting, the rod-shaped metal is connected to the rotating shaft by a fixture. The distance between the cutting head and the rotating shaft is controlled to cut the rod-shaped metal, thereby breaking the rod-shaped metal at the cutting point.

[0003] A search revealed a Chinese patent with authorization announcement number CN217914303U, which discloses a metal cutting machine, including a machine base. The machine base is provided with a first baffle for preventing sparks and debris from flying out of the machine base. A mounting seat is provided on the first baffle, and a cutting blade for cutting metal workpieces is rotatably provided on the side wall of the mounting seat. The machine base is provided with a cutting groove for the cutting blade to pass through in order to cut the metal workpiece.

[0004] Based on the above search results and existing technologies, the following findings were made:

[0005] In the process of cutting metal with existing equipment, the blade will cut thin metal chips from the metal surface. After the cutting operation is completed, the metal chips will fall onto the worktable surface under their own gravity, which is not convenient to clean. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes a metal cutting device that facilitates the cleaning of debris. The device involves moving an L-shaped block backward to move a first clamp, placing a rod-shaped metal piece between clamps one and two. A motor is then started to rotate the rod-shaped metal, which in turn moves a U-shaped frame to move a hydraulic telescopic rod, adjusting the cutting position. The hydraulic telescopic rod then moves downward, causing a cutter on the mounting plate to cut the rod-shaped metal. Baffles one and two shield the debris generated during cutting, preventing it from splashing outwards. Simultaneously, the mounting plate moves downward, causing a rack one on the elongated block to move downward, rotating a gear on the rotating shaft counterclockwise, and causing rack two to move upward. This causes a relative movement of the cleaning plate on the traction rope, positioning the cleaning plate within the shielding frame. After cutting is complete, the hydraulic telescopic rod retracts, and the cleaning plate returns to its original position via a circular block and a telescopic spring, cleaning the debris from the tabletop.

[0007] The technical solution to achieve the purpose of this utility model is: a metal cutting device that facilitates the cleaning of debris, including a tabletop, a U-shaped frame slidably connected to the top of the tabletop, a hydraulic telescopic rod installed on the top of the U-shaped frame, an installation plate fixedly connected to the output end of the hydraulic telescopic rod, and a cutter installed at the bottom of the installation plate; and also includes:

[0008] A cleaning mechanism, located on a desktop;

[0009] The cleaning mechanism includes a moving unit and a cleaning unit. The moving unit includes elongated blocks fixedly connected to both sides of the mounting plate. A rack is fixedly connected to the bottom of each of the two elongated blocks. Rotating shafts are rotatably connected to both inner walls of the U-shaped frame. Gears are keyed to both rotating shafts. A rack is slidably connected to both inner walls of the U-shaped frame. The gears mesh with racks one and two, respectively.

[0010] In some embodiments, the cleaning unit includes four movable holes formed on a U-shaped frame, each of which is slidably connected to a sliding rod. Each of the four sliding rods has a limit block fixedly connected to one end that is far apart from each other. Each pair of sliding rods has a cleaning plate fixedly connected to one end. Each of the two cleaning plates and two racks are equipped with a traction rope.

[0011] In some embodiments, U-shaped rollers are installed on both inner walls of the U-shaped frame, and traction ropes are rotatably connected to both U-shaped rollers.

[0012] In some embodiments, a circular block is fixedly connected to the outer circumferential wall of each of the four sliding rods, and a telescopic spring is sleeved on each of the four sliding rods. The two ends of the telescopic spring are fixedly connected to the circular block and the U-shaped frame, respectively.

[0013] In some embodiments, a sliding groove is provided on the top of the desktop, an L-shaped block is slidably connected in the sliding groove, a second telescopic spring is fixedly connected to the L-shaped block and one inner wall of the desktop, a first baffle is fixedly connected to one side of the L-shaped block, a first clamp is rotatably connected to one side of the first baffle, a motor is fixedly connected to the top of the desktop, the output end of the motor is fixedly connected to the second clamp through a coupling, and a second baffle is fixedly connected to one side of the U-shaped frame.

[0014] In some embodiments, a shielding frame is fixedly connected to each side of the U-shaped frame that is close to the other.

[0015] In some embodiments, the desktop has an elongated hole, and a collection box is installed at the bottom of the desktop, with the elongated hole located below the collection box.

[0016] Compared with existing technologies, the significant advantages of this invention are:

[0017] This invention uses an L-shaped block to move backward, causing the first clamp to move and placing a rod-shaped metal between the first and second clamps. A motor is then started to rotate the rod-shaped metal, and a U-shaped frame moves to move the hydraulic telescopic rod, adjusting the cutting position. The hydraulic telescopic rod then moves downward, causing the cutter on the mounting plate to cut the rod-shaped metal. Baffles one and two shield the debris generated during cutting, preventing it from splashing outwards. As the mounting plate moves downward, it also moves the rack one on the elongated block downward, causing the gear on the rotating shaft to rotate counterclockwise, which in turn moves the rack two upward, causing the cleaning plate on the traction rope to move relative to it, placing the cleaning plate within the shielding frame. After cutting is complete, the hydraulic telescopic rod retracts, and the cleaning plate returns to its original position via the circular block and the telescopic spring, cleaning the debris from the tabletop and causing it to fall into the collection box. This facilitates convenient and unified cleaning of debris from the tabletop.

[0018] This invention solves the problem that in existing equipment, during the metal cutting process, the blade will cut thin metal fragments from the metal surface, and after the cutting operation is completed, the metal fragments will fall onto the worktable surface under their own gravity, which is inconvenient to clean.
