Description

Technical Field

[0001] The present invention relates to the technical field of high-frequency quenching, and particularly to a surface treatment device for metal parts of a coupling. Background Art

[0002] The main purpose of high-frequency quenching of the coupling is to improve its surface hardness and wear resistance while maintaining the toughness of the internal structure. High-frequency quenching generates eddy currents through electromagnetic induction, rapidly heating the surface of the coupling to the quenching temperature, and then forming a high-hardness martensite structure through rapid cooling, thereby enhancing its anti-wear ability and service life.

[0003] Long-term baking of the high-frequency coil by high-temperature workpieces will cause the coil to overheat, thereby affecting its performance and life. The working principle of high-frequency induction heating is to generate an alternating magnetic field in the induction coil through a high-frequency current, generate eddy currents inside the workpiece, and thus generate heat. When a high-temperature workpiece bakes the high-frequency coil for a long time, poor heat dissipation will cause the coil to overheat, damage its insulating material, increase the resistance, and even cause a short circuit; as the coil temperature continues to rise, the insulating material of the coil ages and becomes brittle, and then loses its insulating performance.

[0004] The high-frequency coil and the workpiece to be heated are often very close to achieve sufficient heating effect. However, the baking of the high-frequency coil by high-temperature workpieces will also bring problems. If the high-frequency coil can be effectively cooled, the problems caused by high-temperature baking can be avoided. For this reason, the present invention provides a surface treatment device for metal parts of a coupling. Summary of the Invention

A partial section of the long shaft 30 is movably sleeved in a through hole opened on the integrated frame 12. The end of the long shaft 30 is engaged and transmitted with a row of teeth set on the Z-shaped plate 26 by setting an axis gear.

[0074] The wheel control device 7 includes a pressure shaft 37 with one end movably sleeved in a column hole opened on the equipment plate 9, a spring 36 fixedly sleeved on the other end of the pressure shaft 37, a round box shell 38 fixedly sleeved on the outside of the spring 36, a clamp 35 for clamping the round box shell 38, a plurality of unit folding plates 33 arranged in an arc shape on one side of the round box shell 38, and an arc plate frame 34 supporting the unit folding plates 33, one end of which is fixed on the equipment plate 9.

[0075] The round box shell 38 includes a cylinder body, a plurality of bumps evenly arranged in a ring on the outer side of the cylinder body, and a ring plate arranged at one end of the cylinder body. The pressure shaft 37 is movably sleeved in the middle of the ring plate of the round box shell 38. The unit folding plate 33 slides through the plate hole opened on the arc plate frame 34. One end of the unit folding plate 33 pushed by the bump of the round box shell 38, and the other end of the unit folding plate 33 is meshed and driven with the long shaft gear arranged at the end of the long shaft group 6 by arranging a row of teeth.

[0076] The fixture 35 includes a tail frame 40 fixed on the arc plate frame 34, an intermediate control plate 39 sliding through the plate hole opened on the tail frame 40, and an L-shaped elastic piece 41 fixed at one end on the tail frame 40. A plurality of V-shaped grooves are evenly arranged in a ring on the inner side wall of the cylinder body of the round box shell 38. One end of the intermediate control plate 39 is clamped into the V-shaped groove of the round box shell 38 by arranging a tip, and the other end of the intermediate control plate 39 contacts the other end of the L-shaped elastic piece 41.

[0077] The pressurization assembly 8 includes a disk gear 42 fixed at the end of the pressure shaft 37, a worm 43 meshed and driven on one side of the disk gear 42, and a neck shaft 44 vertically driven with the worm 43. The equipment plate 9 supports the worm 43 and the neck shaft 44 by arranging a concave frame. One end of the neck shaft 44 is meshed and driven with the external gear ring arranged on the flat towing shaft 2 by arranging a gear, and the other end of the neck shaft 44 is variably driven with the bevel gear fixed on the worm 43 by arranging a bevel gear. The worm 43 and the neck shaft 44 are respectively movably sleeved in two through holes opened on the concave frame.

[0078] A flat towing shaft 2 is externally connected to a driving mechanism in the prior art. The flat towing shaft 2 rotates to drive the coupling 1 to slowly rotate. The outer side wall of the coupling 1 successively passes through the heating areas of a plurality of high-frequency coils 10 arranged in an arc. In order to avoid the high-temperature coupling 1 continuously baking the high-frequency coils 10, each high-frequency coil 10 takes turns to move away from the high-temperature coupling 1, and the high-frequency coil 10 is automatically powered off after moving away.

[0079] The drive principle of the high-frequency coil 10 taking turns to move away from the coupling 1: The flat-dragging shaft 2 drives the neck shaft 44, and then drives the disk gear 42 through the worm 43. The disk gear 42 drives the feeding press shaft 37 to rotate slowly. The rotation of the feeding press shaft 37 causes the spring 36 to store energy. When the stored energy is sufficient, it will break the clamping pressure between the intermediate control plate 39 and the round box shell 38. Then the round box shell 38 rotates quickly. Subsequently, the next V-shaped groove on the intermediate control plate 39 and the round box shell 38 is clamped. In this way, the round box shell 38 rotates intermittently. Each time the round box shell 38 stops, it will last for a period of time. At the same time, a convex block on the round box shell 38 will push the unit folding plate 33, and then the unit folding plate 33 moves to drive the long shaft 30 to rotate. Subsequently, it rotates through the range-increasing gear 31 to drive the straight rack 13 to move. Then the power-on switch 11 drives the high-frequency coil 10 to move away from the coupling 1. After the high-frequency coil 10 moves away from the coupling 1, the power connection between the power-on switch 11 and the circuit on the integrated frame 12 is disconnected. Since the convex blocks on the round box shell 38 at the source push the unit folding plate 33 in turn, multiple high-frequency coils 10 arranged in an arc take turns to move away from the coupling 1.

[0080] When a single high-frequency coil 10 moves away from the coupling 1, the remaining stationary high-frequency coils 10 continue to heat the outer wall of the coupling 1. The locally heated outer wall of the coupling 1 after heating rotates to the nozzle 4, and the nozzle 4 sprays warm water to cool the coupling 1. Refer to Figure 7 , the hard water pipe 17 at the right end is externally connected to the water supply mechanism. The water flow will be heated by a row of water heaters 5 before flowing into the nozzle 4. After heating, it is injected into the nozzle 4. Specifically, the water flow diffuses from one hard water pipe 17 into multiple heating fins 14, and then converges in another hard water pipe 17 and continues to be transported to the hard water pipe 17 of the next water heater 5. The front of the energized high-frequency coil 10 heats the coupling 1, while the back heats the water flow flowing through the heating fins 14.

[0081] During the process of the high-frequency coil 10 moving away from the coupling 1, the high-frequency coil 10 gradually approaches the heating fins 14. Multiple heating fins 14 in a group of heating fins 14 move closer together. Then the approaching heating fins 14 are inserted between the two parallel segments on the high-frequency coil 10, and the high-frequency coil 10 successfully moves away from the coupling 1. The principle of multiple heating fins 14 in a group of heating fins 14 moving closer together: The long shaft group 6 rotates to drive the Z-shaped plate 26. The Z-shaped plate 26 drives the L-shaped adjusting plate 28 to move synchronously through the S-shaped elastic piece 27. Then the rotation of the bidirectional shaft gear 21 causes the inverted L-shaped plate 20 and the positive L-shaped plate 19 to approach. The left-position frame 24 and the right-position frame 25 both move synchronously, but in opposite directions. Refer to Figure 6 , there are three groups of heating fins 14. Each group of heating fins 14 contains three heating fins 14. The middle heating fin 14 in each group of heating fins 14 does not move, and the heating fins 14 on both sides approach the middle heating fin 14.

[0082] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
