Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of fastener manufacturing technology, and more specifically, to a quenching apparatus for fastener manufacturing. Background Technology
[0002] Quenching is a metal heat treatment process that involves rapidly immersing a workpiece heated to above a critical temperature into a cooling medium such as water, oil, or air to cool it quickly. This alters the internal structure of the material, significantly improving its hardness, strength, and wear resistance. This process utilizes the non-diffusional phase transformation principle of austenite to martensite, achieving high hardness while sacrificing some toughness. Quenching is often followed by tempering to adjust residual stress and balance mechanical properties. Its applications cover key components such as cutting tools, molds, and gears, and it is a core means of improving the mechanical properties of steel materials.
[0003] In the existing technology, operators often use corresponding quenching devices to quench fasteners during the production process. Although the existing quenching devices have basic quenching functions, their simple structure means that the fasteners are relatively fixed in position after being placed in the quenching box, and the temperature of the cooling medium around the fasteners gradually rises and eventually boils, thus reducing the quality of subsequent quenching operations. Therefore, improvements are needed. Utility Model Content
[0004] To overcome the above-mentioned defects, embodiments of this disclosure provide a quenching apparatus for fastener production, which solves the technical problem of low quenching efficiency in the prior art.
[0005] According to one aspect, at least one embodiment of this disclosure provides a quenching apparatus for fastener production, including a base plate, a quenching box fixedly connected to the top of the base plate, a support base fixedly connected to the top of the base plate, a motor fixedly installed inside the support base, a rotating shaft fixedly connected inside the motor, a rotating rod fixedly sleeved at the other end of the output shaft of the rotating shaft, a sleeve rod movably connected to the outer surface of the rotating rod, a vertical rod fixedly connected to the top of the sleeve rod, the top of the vertical rod penetrating through the quenching box and extending into the interior of the quenching box and fixedly connected to a moving plate, the outer surface of the moving plate movably connected to the inner surface of the quenching box.
[0006] As a preferred technical solution of this disclosure, a sealing ring is fixedly installed at the bottom of the quenching box, and the inside of the sealing ring is movably sleeved with the outer surface of the vertical rod.
[0007] As a preferred technical solution of this disclosure, the quenching box has sliding grooves on both the left and right sides of the inner cavity, and the moving plate has sliding blocks fixedly connected to both the left and right sides, with the outer surface of the sliding blocks being movably connected to the inside of the sliding grooves.
[0008] As a preferred technical solution of this disclosure, a first connecting pipe is fixedly sleeved on the lower left corner of the back of the quenching box, and a third connecting pipe is fixedly sleeved on the upper right corner of the back of the quenching box. A liquid pump is fixedly connected to the top end of the first connecting pipe.
[0009] As a preferred embodiment of this disclosure, a second connecting pipe is fixedly connected to the back of the liquid pump, and a cooling pipe is fixedly connected to the other end of the second connecting pipe.
[0010] As a preferred technical solution of this disclosure, a cooling box is fixedly connected to the back of the quenching box, a cooling pipe is fixedly sleeved inside the left side of the cooling box, and the other end of the cooling pipe passes through the cooling box and extends to the outside of the cooling box and is fixedly connected to the other end of the third connecting pipe.
[0011] As a preferred technical solution of this disclosure, a water injection pipe is fixedly sleeved on the lower left corner of the front of the cooling box, and the other end of the water injection pipe passes through the cooling box and extends into the interior of the cooling box.
[0012] As a preferred technical solution of this disclosure, a water outlet pipe is fixedly sleeved on the upper right corner of the front of the cooling box, and the other end of the water outlet pipe passes through the cooling box and extends into the interior of the cooling box.
[0013] As a preferred embodiment of this disclosure, the number of sliding blocks is two, the two sliding blocks are of the same size, and the outer surfaces of the two sliding blocks are smooth.
[0014] As a preferred embodiment of this disclosure, the top of the motion plate is provided with six rectangular holes, which are symmetrical about the center of the motion plate.
[0015] The beneficial effects of the embodiments disclosed herein are as follows:
[0016] 1. This disclosure incorporates a rotating shaft, a rotating rod, a sleeve rod, a vertical rod, and a moving plate. When the motor starts running, the rotating shaft drives the rotating rod to rotate, causing the rotating rod to press and push the sleeve rod. Under the limiting action of the quenching box, the sleeve rod drives the vertical rod and the moving plate to move vertically upwards. This causes the fasteners on the top of the moving plate to move together in the cooling medium inside the quenching box, thus making full use of the cooling medium in the quenching box and preventing the fasteners from staying in the same position, which would cause the temperature of the surrounding cooling medium to rise and affect subsequent quenching operations.
[0017] 2. This disclosure includes a cooling pipe, a third connecting pipe, a cooling box, a water injection pipe, and a water outlet pipe. First, cooling water is injected into the cooling box through the water injection pipe. Then, the liquid pump is started, causing it to draw the heated cooling medium from inside the quenching box through the first connecting pipe and sequentially pass it into the cooling pipe through the second connecting pipe. At this time, the cooling water in the cooling box exchanges heat with the cooling medium in the cooling pipe, achieving a cooling effect on the cooling medium in the cooling pipe. Finally, the water is discharged back into the quenching box through the third connecting pipe, realizing the circulating cooling function of the cooling medium in the quenching box and improving the quenching effect of the device.

[0025] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.
[0026] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."
[0027] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

Therefore, they should not be construed as limitations on this disclosure.
[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0031] like Figures 1-5As shown, a quenching device for fastener production according to an embodiment of the present disclosure is illustrated, including a base plate 1, a quenching box 2 fixedly connected to the top of the base plate 1, a support base 3 fixedly connected to the top of the base plate 1, a motor 4 fixedly installed inside the support base 3, a rotating shaft 5 fixedly connected inside the motor 4, a rotating rod 6 fixedly sleeved at the other end of the output shaft of the rotating shaft 5, a sleeve rod 7 movably connected to the outer surface of the rotating rod 6, a vertical rod 8 fixedly connected to the top of the sleeve rod 7, the top of the vertical rod 8 penetrating through the quenching box 2 and extending into the interior of the quenching box 2 and fixedly connected to a moving plate 9, the outer surface of the moving plate 9 movably connected to the inner surface of the quenching box 2.
[0032] When the motor 4 starts running, it will cause the rotating shaft 5 to drive the rotating rod 6 to rotate, and the rotating rod 6 will squeeze and push the sleeve rod 7. At this time, under the limiting action of the quenching box 2, the sleeve rod 7 will drive the vertical rod 8 and the moving plate 9 to move vertically upward, thereby driving the fasteners on the top of the moving plate 9 to move together in the cooling medium inside the quenching box 2.
[0033] In some examples, a sealing ring 12 is fixedly installed at the bottom of the quenching box 2, and the inside of the sealing ring 12 is movably sleeved with the outer surface of the vertical rod 8.
[0034] Due to the design of the sealing ring 12, leakage of the cooling medium in the quenching box 2 along the outer surface of the vertical rod 8 can be prevented.
[0035] In some examples, the quenching box 2 has sliding grooves 11 on both the left and right sides of the inner cavity, and sliding blocks 10 are fixedly connected to both the left and right sides of the moving plate 9. The outer surface of the sliding block 10 is movably connected to the inside of the sliding groove 11.
[0036] Due to the limiting effect of the slide groove 11, the moving plate 9 will drive the sliding block 10 to move vertically upward.
[0037] In some examples, a first connecting pipe 13 is fixedly sleeved on the lower left corner of the back of the quenching box 2, and a third connecting pipe 17 is fixedly sleeved on the upper right corner of the back of the quenching box 2. A liquid pump 14 is fixedly connected to the top of the first connecting pipe 13.
[0038] When the liquid pump 14 starts running, it will draw the cooling medium inside the quenching box 2 through the first connecting pipe 13.
[0039] In some examples, a second connecting pipe 15 is fixedly connected to the back of the liquid pump 14, and a cooling pipe 16 is fixedly connected to the other end of the second connecting pipe 15.
[0040] The cooling medium drawn by the liquid pump 14 will pass through the second connecting pipe 15 and the cooling pipe 16 in sequence, and finally be discharged back into the interior of the quenching box 2.
[0041] In some examples, a cooling box 18 is fixedly connected to the back of the quenching box 2, and a cooling pipe 16 is fixedly sleeved inside the left side of the cooling box 18. The other end of the cooling pipe 16 passes through the cooling box 18 and extends to the outside of the cooling box 18 and is fixedly connected to the other end of the third connecting pipe 17.
[0042] The cooling medium inside the cooling pipe 16 will exchange heat with the cooling water in the cooling box 18, thereby achieving the function of cooling the cooling medium in the quenching box 2.
[0043] In some examples, a water injection pipe 20 is fixedly fitted to the lower left corner of the front of the cooling box 18, and the other end of the water injection pipe 20 passes through the cooling box 18 and extends into the interior of the cooling box 18.
[0044] When cooling water is added into the interior of the cooling tank 18 through the water injection pipe 20, the cooling water will fill the inner cavity of the cooling tank 18, thereby maximizing the contact area with the cooling pipe 16.
[0045] In some examples, a water outlet pipe 21 is fixedly fitted to the upper right corner of the front of the cooling box 18, and the other end of the water outlet pipe 21 passes through the cooling box 18 and extends into the interior of the cooling box 18.
[0046] When a large amount of cooling water is injected and the liquid level exceeds the outlet pipe 21, the excess cooling water will flow out of the cooling tank 18 through the outlet pipe 21 to ensure that the cooling water inside the cooling tank 18 is always in a flowing state, thereby improving the cooling effect of the cooling tank 18.
[0047] In some examples, there are two sliders 10, both of which are the same size and have smooth outer surfaces.
[0048] This design makes the movement of the sliding block 10 inside the slide groove 11 smoother, while reducing the friction between the sliding block 10 and the slide groove 11 and improving the service life of the sliding block 10.
[0049] In some examples, the top of the motion plate 9 is provided with six rectangular holes 19 evenly spaced, and the six rectangular holes 19 are symmetrical about the center of the motion plate 9.
[0050] The design of the rectangular hole 19 allows the cooling medium located at the top of the moving plate 9 to flow into the bottom of the moving plate 9 through the rectangular hole 19 during the upward movement of the moving plate 9, thereby hindering the movement of the moving plate 9.
[0051] The working principle and usage process of this disclosure are as follows:
[0052] After the fasteners are placed inside the quenching chamber 2 for quenching, the motor 4 is started, which causes the rotating shaft 5 to drive the rotating rod 6 to rotate. The rotating rod 6 then presses and pushes the sleeve rod 7. Under the limiting action of the quenching chamber 2, the sleeve rod 7 drives the vertical rod 8 and the moving plate 9 to move vertically upward. This causes the fasteners on the top of the moving plate 9 to move together in the cooling medium inside the quenching chamber 2, thus making full use of the cooling medium in the quenching chamber 2 and preventing the fasteners from staying in the same position, which would cause the temperature of the surrounding cooling medium to rise and affect subsequent quenching operations.
[0053] When the cooling medium inside the quenching box 2 has undergone multiple quenching operations and its temperature is too high to be cooled down, cooling water is first injected into the cooling box 18 through the water injection pipe 20. Then, the liquid pump 14 is started, which draws the heated cooling medium inside the quenching box 2 through the first connecting pipe 13 and sequentially introduces it into the cooling pipe 16 through the second connecting pipe 15. At this time, the cooling water in the cooling box 18 will exchange heat with the cooling medium in the cooling pipe 16, thereby achieving the cooling effect of the cooling medium in the cooling pipe 16. Finally, it is discharged back into the quenching box 2 through the third connecting pipe 17, realizing the circulating cooling function of the cooling medium in the quenching box 2 and improving the quenching effect of the device.
[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications or substitutions should be covered within the scope of the claims of this disclosure.
