Description

Technical Field

[0001] This utility model relates to the field of quenching equipment technology, specifically a high-frequency quenching device for machining the cutting edge of a clamp body. Background Technology

[0002] Pliers (such as pliers and needle-nose pliers) are commonly used tools for machining, assembly, and maintenance. The hardness and wear resistance of their cutting edges directly determine their service life. High-frequency quenching is a key process to improve the performance of the cutting edges.

[0003] Currently, high-frequency quenching devices for clamp body cutting edges have the following limitations: traditional quenching devices use fixed induction coils, and the clamp body cutting edges are mostly arc-shaped or beveled structures, making it difficult to maintain a consistent gap between the coil and the cutting edge. This results in local heating temperature deviations exceeding 50°C, which can easily lead to "overheating" (cutting edge cracking) or "underheating" (insufficient hardness). When manually placing the clamp body, the relative position of the cutting edge and the coil is prone to shift, especially for clamp bodies produced in batches, where positioning errors can cause fluctuations in quenching quality. In view of this, a high-frequency quenching device for clamp body cutting edge machining is proposed. Utility Model Content

[0012] This utility model provides a high-frequency quenching device for machining the cutting edge of a clamp body.

The protective component 53 is disposed on the output end of the electric telescopic rod 52. The positioning block 54 is connected to the protective component 53. An abutment block 533 is fixedly connected to the side of the first plate 531 away from the electric telescopic rod 52. The first plate 531 is penetrated by a T-rod 534 and is slidably connected to the T-rod 534. A second plate 535 is fixedly connected to the end of the T-rod 534 away from the first plate 531.

[0027] In use, first place the clamp body on the fixed plate 4, then start the electric telescopic rod 52. The electric telescopic rod 52 extends and pushes the first plate 531 to move. Through the T rod 534, it drives the second plate 535 and the positioning block 54 to push the clamp body. When the clamp body abuts against the positioning part 3, the first plate 531 continues to move and compresses the return spring. The T rod 534 slides relative to the first plate 531 until the abutting block 533 triggers the abutting switch 536. The electric telescopic rod 52 stops moving, realizing flexible pushing. At the same time, the stepper motor 81 is started. The stepper motor 81 drives the rotating wheel 82 to rotate.
