The technique is mainly characterized in that the inner side of a centrifugal blade 2 is provided with an airflow partition board 3; the airflow partition board 3 is communicated with the inner side of an air-in jacket 4. The inner wall of a furnace door 12 is provided with a movable door screen 10; the back wall of an inner chamber 8 and chamber body are provided with air holes. The movable door screen is installed on a piston rod of a cylinder 11, and the cylinder 11 is installed on center position of the outer side of the furnace door 12. The utility model provides a vacuum quenching and heat treating equipment which is suitable for materials with low melting point; the vacuum high pressure gas-quench furnace has high airflow capacity, high quenching ability, fast cooling speed and uniform quenching temperature.
Description
One technical field
The utility model belongs to the vacuum heat treatment technology field, is a kind of metallic substance vacuum heat treatment equipment.
Two background technologies
Vacuum high pressure gas quenching is a kind of Technology to the metal parts material surface hardened, it hardens evenly, be out of shape little, do not destroy piece surface smooth finish, the surface working operation after having reduced to quench has improved production efficiency, has reduced cost.Present vacuum hardening equipment is suitable for handling the high-melting point metal part, as notification number is the Chinese patent of CN21668u, discloses a kind of double room negative pressure high flow-rate vacuum air-quenching furnace, is fit to handle rapid steel, the workpiece that stainless steel, elastic element etc. require anaerobic to handle.Also be not fit to handle the vacuum high pressure gas quenching equipment of low melting point metal material at present.
Three technology contents
The purpose of this utility model provides a kind of vacuum hardening Equipment for Heating Processing that low melting material uses that is suitable for, high pressure, and the high gas flow amount, the hardening capacity height, speed of cooling is fast, and quenching temperature is even.
The utility model is achieved in that a side of body of heater is equipped with strong cold blast engine 1, and centrifugation blade 2 is installed in the body of heater of blower fan inboard, and the body of heater opposite side is provided with fire door 12, and fire door 12 and body of heater are by gear ring 9 lockings; Air intake cover 7 is installed in double-deck water cooled furnace wall 6, in the air intake cover 7 flue 8 is installed, the major technique feature is: the inboard of centrifugation blade 2 is provided with air-flow division board 3, and air-flow division board 3 is communicated with by blast pipe 4 with air intake cover 7 inboards; Fire door 12 inwalls are provided with dodge gate screen 10;
Dodge gate screen 10 is installed on the piston rod of cylinder 11, and cylinder 11 is installed in the central position in fire door 12 outsides.
The utility model high-pressure gas quenching furnace is owing to adopt distinctive pressure cold wind loop structure, the cold gas physical efficiency is circulated apace and cools off, thereby make the workpiece quench cooling rate fast, and hardening capacity is good; Simultaneously, the cold gas physical efficiency sprays to workpiece equably from all directions, makes the workpiece quenching temperature even, reduces distortion, and the vacuum hardening thermal treatment of warm fusing point material is for example aluminium base in being particularly suitable for, copper-based material etc.
