[0002] Tungsten steel possesses excellent properties such as high hardness and high temperature resistance. Molds made of tungsten steel are resistant to stamping and have a long service life, and are mainly used in machining, stamping die manufacturing, precision instruments, and national defense industries. However, existing deburring devices for tungsten steel molds have shortcomings. The pressure between the workpiece and the wire wheel is unstable and difficult to adjust, making it impossible to remove burrs evenly. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a deburring device for tungsten steel mold processing.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a deburring device for tungsten steel mold processing, comprising several side plates, a top plate, a worktable, a motor, a wire wheel, and a chuck. The top of the side plates is vertically connected to the edge of the top plate, the worktable is horizontally connected to the middle of the side plates, the motor is connected to the center of the top plate, and the output shaft of the motor is connected to the wire wheel through the chuck.

[0005] The deburring device for tungsten carbide mold processing also includes a cylinder, several guide rods, several linear bearings, a lifting plate, a vise, a pressure regulating valve, an air pipe, and a workpiece. The center of the worktable has a through hole. The fixed end of the cylinder is connected to the lower surface of the worktable, and the movable end of the cylinder passes through the through hole and is connected to the lifting plate. A vise is connected to the lifting plate, and the workpiece is clamped in the vise. The guide rods are connected to the lower surface of the lifting plate and slide through the worktable via linear bearings. The linear bearings are fixedly connected to the worktable. The air inlet of the cylinder is connected to the air pipe via the pressure regulating valve.

[0006] The present invention is further configured such that: an output pipe is inserted into the top plate, one end of the output pipe is connected to a nozzle, the other end is connected to a storage tank, and a pump is connected in series in the middle of the output pipe; the nozzle is positioned facing the wire wheel.

[0007] A further feature of this invention is that a filter cover is connected to one end of the output pipe that extends into the storage tank.

[0008] The present invention is further configured such that: a liquid collection tank is provided on the edge of the workbench, and a conduit is connected to the bottom of the liquid collection tank. The conduit is vertically arranged and its lower end is inserted into the storage tank.

[0009] The present invention is further configured such that the lifting plate and the vise are fixedly connected by a bolt and nut assembly.

[0010] The present invention is further configured such that: a threaded hole is provided on the top plate, a limit rod is screwed into the threaded hole, a hand ring is connected to the top end of the limit rod, and the bottom end abuts against the vise after it has been raised.

[0011] Compared with existing technologies, the advantages of this utility model are as follows: The movable end of the cylinder is connected to the lifting plate through a through hole. A vise is connected to the lifting plate, and the workpiece is clamped in the vise. The movable end of the cylinder pushes the lifting plate, vise, and workpiece upward until they contact the wire wheel. The wire wheel rubs against the workpiece to remove burrs. Because the guide rod is connected to the lower surface of the lifting plate and slides through the worktable via a linear bearing, the lifting plate, vise, and workpiece cannot rotate. The cylinder inlet is connected to the air pipe through a pressure regulating valve. The pressure regulating valve adjusts the air pressure inside the cylinder to maintain an appropriate upward thrust from the movable end of the cylinder. When the wire wheel slightly pushes the workpiece downward, the gas inside the cylinder can be compressed, maintaining a constant pressure between the workpiece and the wire wheel.

[0015] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0016] See appendix Figure 1-2As shown, a deburring device for tungsten carbide mold processing in this embodiment includes several side plates 1, a top plate 2, a worktable 3, a motor 11, a wire wheel 12, a chuck 13, a cylinder 4, several guide rods 5, several linear bearings 6, a lifting plate 7, a vise 8, a bolt and nut assembly 9, a pressure regulating valve 16, an air pipe 17, and a workpiece 10. The top of the side plate 1 is perpendicularly connected to the edge of the top plate 2. The worktable 3 is horizontally connected to the middle of the side plate 1. The motor 11 is connected to the center of the top plate 2. The output shaft of the motor 11 passes through the chuck 13. The cylinder 4 is connected to the wire wheel 12; the center of the workbench 3 is provided with a through hole 25, the fixed end of the cylinder 4 is connected to the lower surface of the workbench 3, the movable end of the cylinder 4 passes through the through hole 25 and is connected to the lifting plate 7, the lifting plate 7 is connected to the vise 8, the lifting plate 7 and the vise 8 are fixedly connected by bolt and nut assembly 9, and the vise 8 clamps the workpiece 10; the guide rod 5 is connected to the lower surface of the lifting plate 7, and is fixedly connected to the workbench 3 by sliding through the linear bearing 6 36; the air inlet of the cylinder 4 is connected to the air pipe 17 through the pressure regulating valve 16.

[0017] The movable end of cylinder 4 is connected to lifting plate 7 through through hole 25. A vise 8 is connected to lifting plate 7, clamping workpiece 10. The movable end of cylinder 4 pushes lifting plate 7, vise 8, and workpiece 10 upwards until they contact wire wheel 12. Wire wheel 12 rubs against workpiece 10, removing burrs. Since guide rod 5 is connected to the lower surface of lifting plate 7 and slides through worktable 3 via linear bearing 6, lifting plate 7, vise 8, and workpiece 10 cannot rotate. The air inlet of cylinder 4 is connected to air pipe 17 via pressure regulating valve 16. The pressure regulating valve 16 adjusts the internal air pressure of cylinder 4 to maintain an appropriate upward thrust of the movable end of cylinder 4. When wire wheel 12 slightly pushes workpiece 10 downwards, the gas inside cylinder 4 can be compressed, maintaining a constant pressure between workpiece 10 and wire wheel 12. Preferably, pressure regulating valve 16 is an adjustable pressure reducing valve or throttle valve.

[0018] To reduce the temperature of the wire wheel 12 and the workpiece 10, this invention is further configured as follows: an output pipe 23 is inserted into the top plate 2, one end of the output pipe 23 is connected to a nozzle 24, and the other end is connected to a storage tank 20. A pump 22 is connected in series in the output pipe 23; the nozzle 24 is positioned facing the wire wheel 12. A filter cover 21 is connected to one end of the output pipe 23 that extends into the storage tank 20. The storage tank 20 contains cutting fluid, which is sprayed sequentially through the filter cover 21, pump 22, output pipe 23, and nozzle 24 onto the rotating wire wheel 12, thereby reducing the temperature of the wire wheel 12 and the workpiece 10, and washing away the burrs that have been removed from the surface of the workpiece 10.

[0019] To recover cutting fluid and burr debris, this invention further includes a collection tank 18 at the edge of the workbench 3. A conduit 19 is connected to the bottom of the collection tank 18, and the conduit 19 is vertically positioned with its lower end inserted into the storage tank 20. Cutting fluid and burr debris enter the storage tank 20 through the collection tank 18 and the conduit 19. The cutting fluid is then pumped by the pump 22 for reuse. Burr debris is deposited in the storage tank 20.

[0020] To limit the maximum upward movement of the workpiece 10, this invention further includes a threaded hole 26 on the top plate 2, into which a limiting rod 15 is screwed. A hand ring 14 is connected to the top of the limiting rod 15, and its bottom abuts against the vise 8 after it has risen. By rotating the hand ring 14, the limiting rod 15 rotates within the threaded hole 26, changing the position of its bottom. The limiting rod 15 abuts against the vise 8, preventing the vise 8 from rising further and limiting the maximum upward movement of the workpiece 10.

[0021] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
