Problems solved by technology

At present, in order to ensure the surface hardness and the uniformity of the hardened layer, copying coils or cylindrical inductors are usually used to perform induction quenching heating on individual parts. Low and there will be deviations in surface hardness and hardened layer between one or several groups of parts
The quality of the product is closely related to the operating level of the employees, and it is impossible to achieve continuous large-scale production in batches

Abstract

The invention discloses a high-frequency quenching inductor. The high-frequency quenching inductor comprises a cooling liquid inlet pipeline, a cooling liquid outlet pipeline, a first graphite block, a second graphite block and at least one hollow coil. The first graphite block is provided with at least one boss, and the second graphite block is provided with at least one matched boss. The bosses and the matched bosses are in one-to-one correspondence and are arranged symmetrically. The starting ends of the hollow coils are communicated with the cooling liquid inlet pipeline, extend to the matched bosses after winding around the bosses by one circle and are communicated with the cooling liquid outlet pipeline after winding around the matched bosses by one circle. Portions, respectively winding around the bosses and the matched bosses, of the hollow coils are U-shaped. The high-frequency quenching inductor has the advantages that uniformity in induction quenching of components and uniformity in product quality are guaranteed, continuous mass production of heat treatment of small shaft type or spring components is achieved, and production efficiency is improved remarkably.

Description

technical field [0001] The invention relates to a high-frequency quenching inductor, which belongs to the technical field of mechanical equipment. Background technique [0002] At present, in order to meet the surface wear resistance of various small shaft parts and the high stress requirements of spring parts, belt furnace quenching + salt bath tempering can also be used to form a martensitic layer. The method of type furnace + salt bath tempering consumes a lot of energy, and requires special equipment to control the atmosphere in the furnace and isolate the outside air from entering the furnace. Once the air isolation device in the furnace fails, it is often necessary to scrap all the equipment in the furnace. parts to prevent decarburized off-spec parts from flowing to customers. In addition, every time a belt furnace is used to process parts, it is necessary to place 3 to 5 pieces of samples in advance. After the samples pass the test, they can be put into batches of p...
