The invention discloses a cutting device and method for automobile air conditioner plastic part machining, and relates to the technical field of plastic part cutting machining. According to the cutting device and method for machining the plastic parts of the automobile air conditioners, the cutting device comprises a shell and a cutting tool bit which is arranged in the shell and used for cutting the plastic parts of the automobile air conditioners, and an electric push rod is fixed in the shell; a cutting assembly used for cutting the automobile air conditioner plastic part and a maintaining assembly used for keeping the flatness of a cutting tool bit are arranged in the shell, the cutting assembly comprises a supporting column, and one end of the supporting column is detachably connected with the cutting tool bit and used for providing supporting force for the cutting tool bit; the surface quality and the size precision of the automobile air conditioner plastic parts are prevented from being affected, the interval duration of cutting machining of each cutting tool bit is prolonged, the cooling time of the cutting tool bits is prolonged, and therefore the product quality of the automobile air conditioner plastic parts obtained after cutting machining is improved.

This utility model relates to the field of quenching technology for high-elasticity spring production, specifically a rapid quenching device for stainless steel bars used in high-elasticity spring production. The device includes a base column and a worktable. An induction control box is fixedly connected to the upper surface of the worktable. Three induction copper tubes, all arc-shaped, are provided on one side of the control box. A clamping device is provided on the upper surface of the worktable, comprising a sliding groove. The groove is formed on the upper surface of the worktable, and a first screw is rotatably connected to the inner wall of the groove. A slider is slidably connected to the inner wall of the groove, and the slider is threadedly connected to the first screw. This utility model solves the problem that existing quenching equipment requires manual clamping of the bars using special tools, which easily leads to burns to operators during quenching and significantly increases labor costs due to prolonged clamping.
