Description

Technical Field

[0001] The utility model relates to the technical field of quenching, in particular to an induction heating device for quenching a knife shaft. Background Art

[0002] Quenching equipment refers to equipment for solution treatment of materials or heat treatment processes with a rapid cooling process. It is mainly divided into medium frequency quenching furnace, high frequency quenching furnace, industrial frequency quenching furnace, CNC quenching machine tools, and integrated quenching machine tools. The quenching equipment itself is mainly composed of three parts: quenching machine tools, medium and high frequency power supplies, and cooling devices. It allows the supercooled austenite to transform into martensite or bainite, so as to greatly improve the strength, hardness, wear resistance, fatigue strength and toughness of the steel, thereby meeting the different use requirements of various mechanical parts and tools.

[0003] The existing induction heating for quenching the knife shaft generally clamps the knife shaft by manually holding a clamping piece, and then places it on the heating ring of the heater for heating. After the heating is completed, the knife shaft is continued to be clamped and quickly placed in a pool of water for cooling. However, manual clamping of the knife shaft for a long time causes severe pain in the hands, consumes high labor costs, and the production efficiency of the knife shaft is also very low; according to the induction heating device for quenching the knife shaft disclosed in the authorization announcement number CN 215328223 U, when in use, the semicircular rod is first slid to the bottom end of the rotating plate, at which time the semicircular rod will support the rotating rod, at this time the knife shaft is placed on the rotating plate, and the machine is started to heat the heating ring. When the heating is completed, the pedal is stepped down, and the pedal will drive the rope at its top to move. At this time, the rope will pull the semicircular rod through the cylinder to move in the direction away from the rotating plate. At this time, the rotating plate will no longer be supported by the semicircular rod, and the rotating plate will be rotated downward by the gravity of the knife shaft above it. At this time, the knife shaft will fall into the pool and be heated by the pool The water in the water pool is used for cooling to achieve the quenching effect. However, the existing induction heating device for quenching the knife shaft requires manual continuous stepping on the foot pedal to operate. The manual operation next to the heating ring is prone to accidentally touching the knife heating ring due to fatigue or other reasons, resulting in burns, which poses a great safety hazard. Moreover, the existing knife shaft quenching device is relatively inefficient in quenching the knife shaft. All the quenched knives are placed in the water pool and need to be fished out by manual operation of a complex structure, which consumes a lot of labor costs. Therefore, we propose an induction heating device for quenching the knife shaft. Utility Model Content

A heating tube 5 is arranged outside the heater 2, and the bottom end of the feeding mechanism 4 is located inside the water pool 3, so that the heated knife shaft can be placed in the water pool 3 for cooling. During the transportation process, the cooled knife shaft can be transported to the end away from the heater 2, which is convenient for the operator to take it, so that the operator can stand at the end away from the heating tube 5, avoiding the risk of scalding the operator.

[0018] It should be noted that when the utility model is used, the operator stands at one end of the water pool 3 away from the heater 2, and clamps the knife shaft to be quenched in the knife shaft clamping groove of multiple placement plates 12. The device is provided with a controller for control, which controls the rotating motor 15 to work, so that the rotating shaft 6 rotates. The rotation of the rotating shaft 6 drives the two first sprocket wheels 7 thereon to rotate. Through the transmission connection of the two first sprocket wheels 7 and the two second sprocket wheels 9, the two chains 10 on both sides of the water pool 3 move counterclockwise, so that the placement plates 12 are transported to the heating tube 5 one by one, and the knife shaft on the placement plate 12 is heated by the operation of the heater 2. After the heating is completed, the controller controls the rotating motor 15 to continue working, so that the heated knife shaft is transported to the water pool 3 for cooling, and the knife shaft on the other placement plate 12 to be heated is transported to the heating tube 5 for heating, and the process is carried out in sequence to realize the automatic quenching process of the knife shaft. The cooled knife shaft is transported to the operator, and the quenched knife shaft can be removed by the bracket.

[0019] The feeding mechanism 4 includes a rotating shaft 6, a first sprocket 7, a fixed plate 8, a second sprocket 9, a chain 10, and a conveying plate 11. The rotating shaft 6 is rotatably connected to the two ends of the inner part of the water pool 3, and the first sprocket 7 is fixedly connected to the outer sides of the rotating shaft 6 at both ends in the water pool 3. The fixed plates 8 are symmetrically fixedly connected to the two ends of the top of the water pool 3, and the second sprocket 9 is rotatably connected to the top of the fixed plate 8. Chains 10 are arranged on the outer sides of the first sprocket 7 and the second sprocket 9 at both ends of the water pool 3.

The conveying plates 11 are equidistantly connected between the two chains 10. The setting of the rotating motor 5 is convenient for driving the rotating shaft 6 to rotate. The rotation of the rotating shaft 6 can drive the rotation of the first sprocket 7 at both ends thereof. The first sprocket 7 at one end of the two rotating shafts 6 and the second sprocket 9 on the two fixed plates 8 are connected by the chain 10, so as to realize the conveying of the conveying plate 11.

[0020] It should be noted that by controlling the rotating motor 15 to work, the rotating shaft 6 is rotated, and the rotation of the rotating shaft 6 drives the two first sprockets 7 thereon to rotate. Through the transmission connection between the two first sprockets 7 and the two second sprockets 9, the two chains 10 on both sides of the pool 3 move counterclockwise, so that the placement plates 12 are transported one by one to the heating tube 5.

At this time, the fixing holes on the placement plate 12 correspond to the fastening bolts 14 on the mounting plate 13. The placement plate 12 can be fixedly connected to the top of the conveying plate 11 through the fastening bolts 14. After quenching, there may be a lot of slag on the surface of the placement plate 12. At this time, the fastening bolts 14 can be loosened and the placement plate 12 can be removed for cleaning.
