Description

Technical Field

[0001] The present application relates to the technical field of quenching, and in particular to a high-frequency quenching mechanism for a tool. Background Art

[0002] Quenching is a heat treatment process that heats steel to above the critical temperature, keeps it warm for a certain period of time, and then cools it at a rate greater than the critical cooling rate to obtain an unbalanced structure dominated by martensite (or bainite or single-phase austenite as required). Quenching is the most widely used process in steel heat treatment. Through quenching, the rigidity, hardness, wear resistance, fatigue strength and toughness of the tool can be greatly improved to meet various different usage requirements.

[0003] The existing patent (publication number: CN218372394U) discloses a tool ultra-high frequency quenching mechanism, including a support frame, a storage box is provided in the support frame, legs are provided at the four vertices on the lower side of the storage box, a power supply host is placed in the storage box, and a shock-proof block is provided at the lower end of the leg; a quenching mechanism, the quenching mechanism is arranged at the upper end of the support frame, and the quenching mechanism includes an emergency stop switch, a push button switch is provided on the rear side of the emergency stop switch, a clamping test structure is provided on the rear side of the push button switch, and a C-type table is provided on the right side of the button switch, the upper end of the C-type table is rotatably connected to a rotating wheel, a quenching positioning fixture is provided every 90 degrees on the front side of the rotating wheel, and a servo motor is connected to the rear side of the rotating wheel, a quenching machine is provided on the right side of the rotating wheel, and a display screen is provided on the rear side of the quenching machine. The entire device has high tool clamping efficiency, uniform quenching, high quenching efficiency and high safety factor.

[0004] However, during the use of the above-mentioned quenching mechanism, for some longer cutting tools, the quenching positioning fixture can only fix one end of the cutting tool, and the other end and the middle end of the cutting tool are in a suspended state. Although the first clamp is provided with an arc-shaped groove, the contact surface of the cutting tool of the second clamp is a vertical plane, resulting in limited contact area with the cutting tool and unstable fixation. The cutting tool is easy to fall during the rotation of the rotating wheel, affecting the normal quenching. At the same time, the quenching chassis can only move on the slide rail seat toward or away from the cutting tool. For some longer cutting tools, it cannot move horizontally on the surface of the cutting tool, and its cutting edge cannot be evenly heated. Utility Model Content
