Problems solved by technology
The chute is a contour composed of multiple arcs and straight lines, and the deformation trends of the high-frequency quenching area, transition area and non-quenching area of the chute are different. It is difficult to control the range required by the drawing by using conventional high-frequency quenching methods
In addition, the opening of the chute is relatively small, and the small-diameter copper pipe coil enters the slot for heating, and the heating efficiency is slow, so it is difficult to meet the hardness and width requirements of quenching.

The invention discloses a quenching device for precisely punched parts. The quenching device comprises a stationary fixture for fixing the precisely punched parts to reduce the deformation of the precisely punched parts, a high-frequency heating sensor for performing local heating on the precisely punched parts and a water spraying device for spraying water onto the quenched regions of the precisely punched parts for cooling, wherein the stationary fixture comprises a substrate, a supporting plate and a control panel both fixed on the substrate, a positioning nail located on the substrate and used for positioning the precisely punched parts, and a supporting nail located on the substrate and used for supporting the precisely punched parts above the substrate; the control panel is supported above the substrate by use of the supporting plate; the distance between the bottom end face of the control panel and the substrate is equal to the distance between the bottom end face of each precisely punched part and the substrate; and the positioning portion of the control panel is matched with the sliding groove of each precisely punched part so that the precisely punched part can be fixed on the substrate. The quenching device is capable of guaranteeing the dimensional accuracy of the quenched precisely punched parts.
Description
technical field [0001] The invention relates to the technical field of heat treatment, in particular to a quenching device and a quenching method for fine blanking parts. Background technique [0002] The fine-blanking parts with chute applied to electrical appliances, because the chute part and the matching shaft move in a certain trajectory, therefore, the parts on both sides of the chute require high-frequency quenching, and the dimensional tolerances are strict. The chute is a contour composed of multiple arcs and straight lines, and the deformation trends of the high-frequency quenching area, transition area and non-quenching area of the chute are different. It is difficult to control the range required by the drawing by conventional high-frequency quenching methods. In addition, the opening of the chute is relatively small, and the small-diameter copper tube coil enters the opening for heating, and the heating efficiency is slow, so it is difficult to meet the hardne...
