Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of protective hoods, in particular to a fume hood for hardware processing. Background Art
[0002] The existing processing steps for standard hardware parts such as bolts and screws generally involve cutting steel bars and then directly punching the overall shape through a stamping machine. Due to the preheating process before stamping and the metal deformation during stamping, the temperature of the finished workpiece will be extremely high. When the newly processed workpiece enters the discharge hopper, the oil stains attached to the workpiece surface will evaporate into a large amount of oil smoke, polluting the surrounding air and affecting the processing environment.
[0003] In the existing processing procedures, a negative pressure hood and a negative pressure pipe are set on the outside of the discharge hopper to extract the oil smoke. In this process, the workpiece will be cooled by the flowing air, and the oil smoke will be greatly reduced. Then it can be transferred for the next processing. However, sometimes the workpiece processing volume is too large, and the discharge hopper is piled up too much and cannot be cooled in time. When temporary material separation is required, the outflowing workpiece will still emit a large amount of oil smoke, and the oil smoke cannot be sucked out by the negative pressure hood because it has left the shroud range. When the workpiece is separated and flows out, it may also cause splashing due to collision, scalding the surrounding staff. Therefore, a fume extraction hood that can protect and block during material separation is needed. Utility Model Content
