Description

Technical Field

[0001] The utility model relates to the technical field of spring processing, in particular to a quenching device for spring processing. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under external force and return to their original shape after the external force is removed. They are generally made of spring steel. There are many types of springs. According to their shapes, they mainly include helical springs, scroll springs, leaf springs, special-shaped springs, etc. In the process of making springs, in order to make the surface of the spring have strong hardness, wear resistance and fatigue strength, while the core still has high toughness, it is necessary to use quenching equipment to treat the surface of the spring.

[0003] With respect to the above-mentioned related technologies, the inventors found that when quenching a spring with a larger shape, the heated spring is usually lifted by a hook, and then the hook is connected to the lifting frame, and the lifting frame is operated to move downward so that the spring is immersed in cold oil for rapid cooling, thereby enhancing the hardness, wear resistance and fatigue strength of the spring surface. However, the spring is immersed in the cold oil and is in a stationary state. After the cold oil in the area near the spring absorbs a large amount of heat, the temperature rises sharply, causing the cooling rate of the spring to drop rapidly, thereby reducing the quenching effect. Utility Model Content

[0004] The utility model mainly solves the technical problem of providing a quenching device for spring processing, which enables the spring to perform circular rotation and relatively linear movement in the cold oil of an oil container, quickly dissipates the heat in the spring into the cold oil, and improves the quenching effect.

[0006] It also includes a longitudinal driving mechanism for driving the oil container body to move linearly back and forth.

[0007] By adopting the above technical solution, when in use, an appropriate amount of cold oil is injected into the oil container, the hook is connected to the heated spring, the hook is inserted into the hanging assembly and is in a hanging state, the telescopic rod assembly is operated to make the spring move downward and then immersed in the cold oil, the heat in the spring is quickly dissipated to the cold oil, and the purpose of cooling is achieved. At this time, the rotating assembly is operated to drive the spring to rotate in a circle, and at the same time, the longitudinal drive mechanism is operated to drive the oil container to move linearly back and forth, so that the spring dissipates heat during the process of rotating and moving relatively linearly in the cold oil, that is, the spring is always in contact with the cold oil with a lower temperature, thereby quickly dissipating heat and improving the effect of spring quenching.

[0008] In a preferred example, the utility model can be further configured as follows: the telescopic rod assembly includes a vertical electric push rod and four guide rods arranged on the outside of the vertical electric push rod, the rectangular array of guide rods is installed on a U-shaped frame, and the vertical electric push rod is installed on the U-shaped frame.

[0009] By adopting the above technical solution, the telescopic rod of the vertical electric push rod extends and retracts, thereby driving the spring to move into or out of the cold oil in the oil tank, without requiring excessive intervention from workers, thereby reducing the labor intensity of workers.

[0010] In a preferred example, the utility model can be further configured as follows: the rotating component includes a slewing support, a mounting plate and a driving gear, the driving gear is meshingly connected to the slewing support, the mounting plate is fixedly connected to the circular plate, a servo motor is connected to the mounting plate, and the output shaft of the servo motor is sleeve-connected with the driving gear.

[0011] By adopting the above technical solution, the servo motor drives the driving gear to rotate, the driving gear drives the slewing support to rotate, the slewing support drives the hanging assembly to rotate, and the hanging assembly drives the spring to rotate in the cold oil, thereby improving the cooling efficiency and enhancing the quenching effect.

[0012] In a preferred example, the utility model can be further configured as follows: the hanging assembly includes an annular plate, and the outer circular annular array of the annular plate is provided with a plurality of hanging holes.

[0013] By adopting the above technical solution, since a plurality of hanging holes are provided on the annular plate, a plurality of springs can be hung at the same time for quenching, thereby improving the working efficiency of quenching.

[0014] In a preferred example, the utility model can be further configured as follows: the longitudinal driving mechanism includes a base plate and a longitudinal electric push rod connected to the upper plane thereof, guide rails are respectively connected to the two sides of the longitudinal electric push rod, the base plate is connected to the oil tank body through the guide rails, the protruding end of the longitudinal electric push rod is connected to a movable plate, and the movable plate is connected to the bottom plane of the oil tank body.

[0015] By adopting the above technical solution, the telescopic rod of the longitudinal electric push rod extends and retracts, thereby driving the oil tank to move linearly, that is, the spring moves in the cold oil, which increases the temperature reduction speed in the spring and enhances the quenching effect.

[0016] In a preferred example, the utility model can be further configured as follows: a rectangular clearance hole is provided on the U-shaped frame, and the rectangular clearance hole is located directly above the servo motor.

[0017] By adopting the above technical solution and setting the rectangular clearance hole, the servo motor can move into the rectangular clearance hole, thereby preventing the rotating component from interfering with the U-shaped frame during the rising process.

[0018] In summary, the present invention includes at least one of the following beneficial technical effects:

[0019] The rotating assembly drives the spring connected to the hanging assembly to rotate, and the longitudinal driving mechanism drives the oil tank to move, so that the cold oil in the oil tank moves relative to the spring, so that the heat on the spring is quickly dissipated into the cold oil, thereby enhancing the quenching effect of the spring.
