Description

Technical Field

[0001] This utility model belongs to the field of smoke collection and exhaust technology, and in particular relates to a smoke exhaust hood for use in a roll forging machine. Background Technology

[0002] Currently, the commonly known exhaust hood for roll forging machines is installed on top of the crossbeam above the forging rolls. The hood is welded from steel plates and structural steel, and is connected to an exhaust duct equipped with a manual valve. When the roll forging machine is operating, the manual valve on the exhaust duct must be opened. When a release agent is sprayed onto the roll forging die, the resulting smoke rises and accumulates in the exhaust hood, then is discharged through the exhaust duct. When the roll forging machine is not operating, the manual valve on the exhaust duct can be closed.

[0003] However, the fume hood installed above the forging rolls obstructs the wire ropes used for hoisting the molds, increasing the difficulty of mold assembly and disassembly. Because the fume hood is installed above the equipment and far from the ground, operators need to climb onto the equipment to operate the valves on the exhaust pipes. This increases the difficulty of opening and closing the valves, poses safety hazards, and wastes energy. Utility Model Content

[0004] In order to overcome the problems of existing exhaust hoods for roll forging machines obstructing mold assembly and disassembly and the exhaust pipe valves being inconvenient to operate, this utility model provides an exhaust hood for roll forging machines. This exhaust hood can not only effectively discharge the smoke generated by spraying release agent, but also does not obstruct mold assembly and disassembly, and does not require manual operation of the exhaust pipe valves.

[0005] This utility model is implemented as follows: a fume hood for a roll forging machine includes a fume hood body, an exhaust hole at the top of the fume hood body, and an exhaust pipe connected to the exhaust hole; the fume hood body has a notch for the steel wire rope to move during mold hoisting, and a movable plate is provided at the notch; the movable plate is rotatably connected to the fume hood body via a hinge, so that the movable plate can rotate to above the fume hood body or to cover the notch on the fume hood body; an electrically controlled valve is installed on the exhaust pipe, and the electrically controlled valve is linked to the roll forging machine.

[0006] In the above technical solution, preferably, the fume hood is installed above the forging rolls of the roll forging machine via a support assembly.

[0007] In the above technical solution, a further preferred embodiment is that the support assembly includes multiple support columns and at least one support beam, the support columns are welded to the top of the crossbeam above the forging roll of the roll forging machine, the support beam is welded to the support columns, and the exhaust hood is welded to the support beam.

[0008] In the above technical solution, it is further preferred that both the support column and the support beam are made of structural steel.

[0009] In the above technical solution, preferably, the smoke hood body is welded from a bent plate and a top plate, and the exhaust hole is located on the top plate.

[0010] The advantages and positive effects of this utility model are: 1. The exhaust hood of this utility model, applied to a roll forging machine, has a notch on one side of the hood body for the movement of the wire rope during mold hoisting, and a rotatable connecting plate is installed at the notch. This ensures the exhaust effect of the hood when the roll forging machine is working, while avoiding obstruction of mold assembly and disassembly when the roll forging machine is not working, thus improving work efficiency. The electrically controlled valve on the exhaust pipe can be opened and closed with the equipment without manual operation, avoiding the safety hazards of operators working at heights, and effectively preventing the exhaust pipe valve from being forgotten to be closed when the equipment is stopped, thus saving energy.

[0011] 2. This utility model relates to a fume hood for a roll forging machine. When the roll forging machine is started, the electrically controlled valve on the exhaust pipe automatically opens, allowing the fume hood to discharge the smoke generated during production. When the roll forging machine is shut down, the electrically controlled valve automatically closes. When it is necessary to disassemble or assemble the mold, the movable plate on the fume hood can be opened to facilitate the entry of the wire rope for hoisting the mold, thus avoiding obstruction of mold hoisting.

[0018] Please see Figures 1-5 This utility model provides a fume hood for a roll forging machine, comprising a fume hood body, an exhaust hole at the top of the fume hood body, and an exhaust pipe 9 connected to the exhaust hole; the fume hood body has a notch for the steel wire rope to move during mold hoisting, and a movable plate 7 is provided at the notch, the movable plate 7 being rotatably connected to the fume hood body via a hinge 8, so that the movable plate 7 can be rotated to be above the fume hood body or to be rotated to cover the notch on the fume hood body; an electrically controlled valve 10 is installed on the exhaust pipe 9, and the electrically controlled valve 10 is linked to the roll forging machine.

[0019] This utility model features a notch in the main body of the fume hood, at which a movable plate 7 is installed. The movable plate 7 is formed by bending a steel plate and is connected to the main body of the fume hood via a hinge 8. The movable plate 7 can cover the notch in the main body of the fume hood. When needed, the movable plate 7 can be opened to avoid the movement space of the hoisting wire rope of the mold. An electric control valve 10 is installed on the exhaust pipe 9. The electric control valve 10 is linked to the rolling forging machine. When the rolling forging machine is started, the electric control valve 10 automatically opens and when the rolling forging machine is shut down, the electric valve automatically closes.

[0020] In a preferred embodiment, the fume hood is mounted above the forging rolls of the roll forging machine via a support assembly, which significantly improves the convenience of equipment maintenance.

[0021] In a preferred embodiment, the support assembly includes multiple support columns 3 and at least one support beam 4. The support columns 3 are welded to the top of the crossbeam 2 above the forging roll 1 of the rolling mill, and the support beam 4 is welded to the support columns 3. The fume hood is welded to the support beam 4. This embodiment provides two support columns 3 and one support beam 4, which form a stable support frame, enhancing the load-bearing capacity of the fume hood and facilitating disassembly and maintenance.

[0022] In a preferred embodiment, both the support column 3 and the support beam 4 are made of structural steel. Structural steel (such as I-beams, channel steel, square steel, etc.) is easy to process, has a long service life, low maintenance costs, and high tensile and compressive strength, enabling the support column 3 and support beam 4 to withstand large loads, including the weight of the fume hood, the vibration and impact forces generated during forging, and the force exerted by the airflow on the fume hood during exhaust.

[0023] In a preferred embodiment, the fume hood body is welded from a bent plate 5 and a top plate 6, with the exhaust vent located on the top plate 6. The processing of the bent plate 5 and the top plate 6 is simple and easy to control. After entering the fume hood, the flue gas can be directly discharged upward along the guide of the top plate 6, allowing the flue gas to smoothly enter the exhaust pipe 9.

[0024] The specific installation process of this utility model is as follows: An exhaust vent is made in the center of the top plate 6. The bent plate 5 and the top plate 6 are welded together to form the smoke exhaust hood body. A notch is left on one side of the smoke exhaust hood body. The movable plate 7 is connected to the smoke exhaust hood body through the hinge 8 so that it can cover the notch on the smoke exhaust hood body.

[0025] Two support columns 3 are welded to the top of the crossbeam 2 above the forging roll 1 of the roll forging machine. The support beam 4 is welded between the two support columns 3. The fume hood body with the movable plate 7 is welded to the support beam 4, and the movable plate 7 is positioned on the mold loading side (that is, the direction of the equipment pulling robot). The exhaust pipe 9 is connected to the exhaust hole on the top plate 6 of the fume hood and welded to the top plate 6. The electric control valve 10 is installed on the exhaust pipe 9. The electric control valve 10 is linked with the roll forging machine. When the roll forging machine is started, the electric control valve 10 automatically opens and when the roll forging machine is shut down, the electric control valve 10 automatically closes.

[0026] When the equipment is running, the fumes generated by spraying the release agent will drift upwards and gather in the exhaust hood above, and be discharged through the exhaust pipe 9. When it is necessary to disassemble or assemble the mold, the movable plate 7 on the exhaust hood can be folded up and opened to facilitate the entry of the wire rope for hoisting the mold and avoid obstructing the mold hoisting. After the mold is installed, the movable plate 7 is closed.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
