Description

Technical Field

[0001] The utility model belongs to the technical field of wire quenching and tempering, and specifically relates to a quenching and tempering spraying device for spring wire processing. Background Technique

[0002] Spring wire is a metallic material with excellent elasticity and toughness. It is usually made of high-carbon steel or alloy steel and has unique properties after a series of fine processing techniques; the surface of the spring wire is smooth and uniform, with precise diameter, and can withstand repeated stretching and compression; its strength and durability make it indispensable in many fields and it is an important part to ensure the normal operation of machinery. Therefore, quenching and tempering is an essential step in the processing of spring wire, and generally a quenching and tempering spraying device is used to perform the quenching and tempering spraying operation on the wire.

[0003] The quenching and tempering spraying device usually consists of a liquid storage tank, a spraying pipeline, a spray head, a pump, a control system, etc.; its principle is to pump the coolant from the liquid storage tank through the pump, transport it to the spray head through the spraying pipeline, and the spray head evenly sprays the coolant on the surface of the workpiece to be quenched and tempered; the structural design of the whole device ensures the sufficient supply and uniform distribution of the coolant to achieve the ideal quenching and tempering effect and improve the properties such as hardness and toughness of the workpiece.

[0004] When the existing quenching and tempering spraying device performs the quenching and tempering spraying operation on spring wire, it is prone to uneven quenching, resulting in large local property differences in the wire. Thus, there will be problems such as insufficient hardness in some parts, while some other parts may be too hard and brittle; and there will be inconsistency in the cooling effect during the spraying process. If the temperature of the coolant rises and the overall cooling capacity decreases, it may lead to unqualified quenching. Therefore, a quenching and tempering spraying device for spring wire processing is proposed to solve the above problems. Content of the Utility Model

[0005] In order to make up for the deficiencies of the existing technology and address the problems existing in the existing equipment, the utility model proposes a quenching and tempering spraying device for spring wire processing.

[0006] The technical solution adopted by the utility model to solve its technical problems is a quenching and tempering spraying device for spring wire processing, including a fuselage. Inside the fuselage, heaters are provided on both sides. The output end of the heater is connected to a lifting rod, and the other end of the lifting rod is provided with a heating plate. One side of the heating plate is fixedly connected to a limiting ring, and a fixing structure is arranged inside the limiting ring. The fixing structure includes a support plate. One side of the fuselage is fixedly connected to a first fixing pin, and a three-way plate is installed outside the first fixing pin. Inside one corner of the three-way plate, a second fixing pin is connected. A first connecting ear is connected outside the second fixing pin, and the other end of the first connecting ear is welded to a guiding plate. A limiting groove is arranged outside the central position of the guiding plate, and one side of the limiting groove is welded to the support plate. At the end of the guiding plate far from the first connecting ear, there are balls. The heating plate is heated by using a heater with the model hj-009, thereby heating the spring wire.

[0007] Preferably, a third fixing pin is arranged inside the other corner of the three-way plate, and a second connecting ear is connected outside the third fixing pin. On the other side of the support plate, there is a support rod. On the side of the support rod close to the support plate, there is a first driving roller, and the first driving roller passes through the support plate and is located on the other side of the support plate. On one side of the first driving roller, there is a guide rail, and a gear roller is meshed inside the guide rail. One side of the gear roller is connected to a connecting block, and the top of the connecting block is connected to a second driving roller. The position of the second driving roller is at the top of the second connecting ear. The device is fixed by pushing the balls through the limiting ring and clamping the fixing structure with the balls. At the same time, the wire is uniformly heated by driving the structure to rotate through a motor.

[0008] Preferably, a fixing rod is arranged outside the motor, and both sides of the fixing rod are welded to the outer wall of the fuselage. The bottom of the water storage tank is communicated with a water inlet, the water inlet is communicated with a condensation spray head, and there is a water outlet on the other side of the condensation spray head. The other end of the water outlet is communicated with the water storage tank. A water pump is arranged inside the water storage tank. A motor is arranged on one side of the center of the support rod, and the output end of the motor is connected to a driving shaft, and the driving shaft is fixedly connected to the support rod. A limiting disc is welded to the port of the driving shaft. The temperature of the sprayed cooling liquid is reduced by adding a condensation device on the top of the spray head.

[0009] The advantages of the utility model are as follows:

[0010] This utility model clamps steel wires of different calibers through the design of adding guide rails and gear rollers inside a fixed structure, and fixes the positions of the steel wires through the fixed structure to ensure that the spring steel wires are in the correct positions and postures during clamping, avoiding mutual occlusion or uneven contact. By using a suitable fixture, good heat conduction is achieved between the steel wire and the fixture, reducing local temperature differences. Moreover, through the design of adding a condensation nozzle inside the device, the coolant in the water storage tank can be cooled and then sprayed, thereby accelerating the cooling speed of the steel wire, avoiding the problem that the quenching may not meet the standard due to the increase in the coolant temperature and the decline in the overall cooling capacity.

One side of the limiting groove 17 is welded to the support plate 12. At the end of the guiding plate 18 away from the first connecting ear 19, there are balls 8. Inside another corner of the three-way plate 14, there is a third fixing pin 22. Outside the third fixing pin 22, a second connecting ear 23 is connected. On the other side of the support plate 12, there is a support rod 15. On the side of the support rod 15 close to the support plate 12, there is a first driving roller 20. The first driving roller 20 passes through the support plate 12 and is located on the other side of the support plate 12. On one side of the first driving roller 20, there is a guide rail 26. Inside the guide rail 26, a gear roller 24 is meshed. On one side of the gear roller 24, there is a connecting block 25. At the top of the connecting block 25, a second driving roller 21 is connected. The position of the second driving roller 21 is at the top of the second connecting ear 23. When fixing and quenching and tempering the wire, first, the operator inserts the wire along the gap between the first driving roller 20 and the second driving roller 21, and then pushes the second driving roller 21. At this time, the gear roller 24 will move inside the guide rail 26, and at the same time drive the second driving roller 21 to move. At the same time, under the action of the connecting block 25, its position is fixed. Then, the operator starts the heater 5. At this time, the lifting rod 3 at the top of the heater 5 starts to rise, and the heating plate 6 is retracted. At this time, the limiting ring 7 on one side of the heating plate 6 starts to retract. At this time, the limiting ring 7 pushes the ball 8 to move, thereby driving the fixing structure to retract. At this time, under the push of the ball 8, the guiding plate 18 starts to rise along the track of the limiting groove 17. Then, under the action of the first connecting ear 19, one side of the three-way plate 14 tilts with the first fixing pin 13 as the center. At the same time, the second connecting ear 23 on the other side of the three-way plate 14 is tightly attached to the wire under the push of the third fixing pin 22, thus completing the fixing operation of the wire.

When quenching and tempering the steel wire, at this time, the operator starts the motor 9, at this time, the motor 9 drives the drive shaft 10 to rotate, and thus the four groups of fixing structures on both sides of the support rod 15 rotate. At this time, the ball 8 rotates along the central positions of the limit disk 11 and the limit ring 7. At the same time, the steel wire is heated by the heating plate 6. After the upper heating is completed, at this time, the cooling liquid inside the water storage tank 2 enters the condensation spray head 28 along the water inlet 27, and then the condensation spray head 28 sprays the steel wire. The remaining water will return to the inside of the water storage tank 2 along the water outlet 29 under the action of the water pump inside the water storage tank 2 to cool the condensation liquid inside the water storage tank 2.

[0021] Working principle: When fixing and quenching and tempering the steel wire, at this time, the operator first inserts the steel wire along the gap between the first driving roller 20 and the second driving roller 21, and then pushes the second driving roller 21. At this time, the gear roller 24 moves inside the guide rail 26, and at the same time drives the second driving roller 21 to move. At the same time, its position is fixed under the action of the connecting block 25. After that, the operator starts the heater 5. At this time, the lifting rod 3 at the top of the heater 5 starts to rise, and the heating plate 6 is retracted. At this time, the limit ring 7 on one side of the heating plate 6 starts to retract. At this time, the limit ring 7 pushes the ball 8 to move, thereby driving the fixing structure to retract. At this time, under the push of the ball 8, the guiding plate 18 starts to rise along the track of the limit groove 17. Then, under the action of the first connecting ear 19, one side of the three-way plate 14 tilts with the first fixing pin 13 as the center. At the same time, the second connecting ear 23 on the other side of the three-way plate 14 is closely attached to the steel wire under the push of the third fixing pin 22, thereby completing the fixing operation of the steel wire; when quenching and tempering the steel wire, at this time, the operator starts the motor 9, at this time, the motor 9 drives the drive shaft 10 to rotate, and thus the four groups of fixing structures on both sides of the support rod 15 rotate. At this time, the ball 8 rotates along the central positions of the limit disk 11 and the limit ring 7. At the same time, the steel wire is heated by the heating plate 6. After the upper heating is completed, at this time, the cooling liquid inside the water storage tank 2 enters the condensation spray head 28 along the water inlet 27, and then the condensation spray head 28 sprays the steel wire.
