Description

Technical Field

[0001] This invention belongs to the technical field of metal material heat treatment machinery and equipment, specifically a quenching equipment that can perform water mist and air cooling from multiple directions. Background Technology

[0002] In material heat treatment testing, because materials are frequently used under various operating conditions, different heat treatment methods are often required to modify their properties. Immersion quenching (after austenitization, the sample or workpiece is directly immersed in a liquid medium) and normalizing are relatively easy to implement and operate. However, for situations requiring a cooling rate between normalizing and immersion quenching, air-cooled atomized quenching is typically employed. This involves using air-cooled water mist to cool the sample or workpiece, thereby obtaining the desired microstructure and properties.

[0003] For example, patent number CN202310573941.3 describes an air-cooled quenching device for aluminum profiles. The air-cooled quenching device includes a pair of air-cooled quenching mechanisms. Each air-cooled quenching mechanism includes a horizontal drive assembly and an air-cooled quenching assembly. The horizontal drive assembly is used to drive the air-cooled quenching assembly to move horizontally. The air-cooled quenching assembly includes several air guide pipes evenly distributed along the horizontal direction. Several evenly distributed radially arranged air nozzles are formed on the inner end of the air guide pipes. When a pair of air-cooled quenching assemblies abut against each other, all the air guide pipes are combined into a pair of coaxial, same-diameter, and same-pitch cylindrical spiral tubes, with one cylindrical spiral tube located in the gap between the other cylindrical spiral tube. The axial direction of the cylindrical spiral tube is parallel to the length direction of the aluminum profile. The air nozzles are evenly distributed along the same cylindrical spiral tube. One end of the cylindrical spiral tube is sealed, and the other end is connected to an external blower.

[0004] Two defects were discovered during actual use:

[0005] 1. This device can only cool the surface of the metal tubular part with air-cooled spray. Its nozzles are all set to be radially perpendicular to the metal part. However, it cannot effectively cool the two ends of the metal part. There is no related cooling device set on both sides. According to the above patent, setting the cooling device on both sides will interfere with the movement of the metal part. Therefore, the above patent results in the metal part not being able to be cooled in a comprehensive manner.

[0006] Second, the cooling device of the above-mentioned patent is arranged in a ring. Therefore, when cooling metal parts, the metal parts can only be suspended in the air for cooling. It is not convenient to use for cooling shorter metal parts, and other cooling equipment is required. This leads to the need for factories to set up multiple sets of quenching equipment, resulting in increased costs, narrow applicability, and low work efficiency. Summary of the Invention

[0007] To address the problems mentioned in the background art, the present invention provides a quenching device capable of multi-directional water mist air cooling. It has the advantages of being able to perform all-round quenching and cooling of metal parts without adding other air cooling spray devices by setting a preset air cooling spray tilt angle, and being able to perform quenching and cooling of metal parts of different sizes, thereby reducing the cost of use and improving work efficiency.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a quenching device capable of multi-directional water mist cooling, including arc-shaped supports fixed on both sides of the bottom of the inner cavity of a wastewater collection tank;

[0009] The cooling mechanism includes hollow support rollers that are rotatably arranged at equal intervals between two arc-shaped supports along the arc direction of the arc-shaped supports, forming an arc shape. The hollow support rollers are divided into left and right ends at their centerline. The upper end of the first oblique hole that is equally divided around the left end is inclined towards the right end, and the upper end of the second oblique hole that is equally divided around the right end is inclined towards the left end, so that the extension lines of the first oblique hole and the second oblique hole intersect. Atomizing heads for spraying are fixed on the inner walls of the first oblique hole and the second oblique hole. The connecting end of the atomizing head is located in the inner cavity of the hollow support roller. Several hollow support rollers need to protrude from the upper end face of the two arc-shaped supports. Metal parts to be quenched are placed on the upper end of several hollow support rollers.

[0010] The left end of the hollow support roller is provided with a second air rotating slip ring for supplying cold water to the atomizing head, and the right end of the hollow support roller is provided with a first air rotating slip ring for supplying cold air to the atomizing head.

[0011] The bottom of the wastewater collection tank is fixed with a support mechanism to support the cooling mechanism. The wastewater collection tank is fixed with a first driving mechanism to drive the metal part to rotate on the axial side of the metal part. The output end of the first driving mechanism is fixed with a rotating clamping mechanism to hold the metal part.

[0012] In the above technical solution, preferably, the cooling mechanism further includes a transmission shaft fixed at both ends of the hollow support roller and movably passing through the arc-shaped bracket. The transmission shaft is configured to have a cavity, and the two transmission shafts are respectively fixedly connected to the rotating ends of their respective second air-rotating slip ring and first air-rotating slip ring.

[0013] In the above technical solution, preferably, each of the arc-shaped brackets has through holes on its side corresponding to the number of cooling mechanisms, and each through hole is fitted with a bearing with an interference fit. Each of the transmission shafts passes through the middle of the fixed bearing and extends to the outside.

[0014] In the above technical solution, preferably, the outer sides of both arc-shaped supports are fixed with mounting brackets for fixing the second air rotating slip ring and the fixed end of the first air rotating slip ring, and the lower middle part of the two arc-shaped supports is fixed to the bottom of the inner cavity of the wastewater collection tank through a support frame. The size of the wastewater collection tank is larger than the width of the arc-shaped supports and the axial distance of the cooling mechanism.

[0015] In the above technical solution, preferably, each of the atomizing heads is provided with a water inlet and an air inlet, the water inlets of the atomizing heads are connected in parallel and fixedly connected to the output pipe of the first air rotating slip ring, and the air inlets of the atomizing heads are connected in parallel and fixedly connected to the output pipe of the second air rotating slip ring.

[0016] In the above technical solution, preferably, the support mechanism includes a support plate fixed to the bottom of the wastewater collection tank, the top of the support plate is located between the two atomizing heads, and a 2mm gap is left between the top of the support plate and the edges of the first and second inclined holes.

[0017] In the above technical solution, preferably, the upper end of the support plate is provided with arc-shaped grooves on both sides with an arc greater than that of the hollow support roller, and a movable groove is provided in the middle of the two arc-shaped grooves. Guide rollers are rotatably provided on both sides of the inner wall of the movable groove through a rotating shaft, and the surface of the guide rollers abuts against the surface of the hollow support roller.

[0018] In the above technical solution, preferably, a chiller for cooling liquid is provided on one side of the wastewater collection tank, and a water pumping mechanism is fixed on one side of the chiller. The cooling end of the chiller cools the water in the water storage tank of the water pumping mechanism.

[0019] In the above technical solution, preferably, a chiller is fixedly installed on the other side of the wastewater collection tank at the position corresponding to the chiller. The air supply end of the chiller and the water supply end of the water pumping mechanism are respectively connected and fixed to the input ends of the two water distributors. The output ends of the two water distributors are respectively fixed and connected to the water inlet end and the air inlet end of the atomizing head.

[0020] In the above technical solution, preferably, the arc-shaped support is a 180-degree arc, wherein two of the cooling mechanisms are located at the two ends of the arc-shaped support, and the remaining cooling mechanisms are equally distributed.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] This invention places a long metal part in an arc-shaped bracket via a transport device, bringing it into contact with a hollow support roller. The hollow support roller supports the metal part, and the jaws of the rotating clamp mechanism open to clamp the metal part. Then, the first drive mechanism drives the rotating clamp mechanism to rotate, thereby causing the metal part to rotate on the upper end of the hollow support roller. Simultaneously, the hollow support roller rotates, and the refrigeration unit, air cooler, and water pumping mechanism work together. The water outlet pipes of the water distributor deliver cooling water to the water inlet of each atomizing head. At the same time, the air cooled by the air cooler is delivered to the water distributor through the air outlet pipe. The air outlet pipes of the water distributor deliver high-pressure air to the air inlet of each atomizing head. The atomizing head mixes the high-pressure air with the cooling water and sprays it out to achieve a mist. The tilted atomizing head sprays the cooling air and atomized water onto the surface of the metal part to achieve quenching.

[0023] This invention addresses the issue that if the length of the metal part is longer than the length of the hollow support roller, a linear drive mechanism is needed to move the metal part back and forth laterally on the surface of the hollow support roller, so that one end of the metal part can be within the spray range of the atomizing head, thereby enabling the two ends to be quenched alternately.

[0024] This invention utilizes a motor to drive a gear that rotates an external gear ring when the metal part to be quenched is short. This gear ring, in turn, drives a hollow support roller directly connected to the drive gear to rotate. The external gear ring of the hollow support roller then drives a transition gear to rotate, which in turn drives other hollow support rollers to rotate, thereby rotating the metal part. This, in conjunction with the quenching equipment, achieves the quenching effect.

[0025] In summary, this invention can perform quenching and cooling of metal parts in all directions, and can also perform quenching and cooling of metal parts of different sizes, thereby reducing usage costs and improving work efficiency. Attached Figure Description

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0043] Example 1

[0044] like Figures 1 to 9As shown, the present invention provides a quenching device capable of multi-directional water mist cooling, including arc-shaped supports 6 fixed to both sides of the bottom of the inner cavity of the wastewater collection tank 1 by anti-rust bolts. The distance between the two arc-shaped supports 6 can be set to 5m, 7m or 10m, etc., but is not limited to, and is set according to the length of commonly used columnar workpieces. Similarly, the curvature of the arc-shaped supports 6 is also set according to specific circumstances. The metal part 11 can be accommodated in the arc-shaped supports 6. The arc-shaped supports 6 are preferably 180-degree arcs with the largest opening distance, which can quench columnar metal parts 11 with a larger diameter. The two cooling mechanisms 8 are located at the two ends of the arc-shaped supports 6. The distance between the two ends and the surface of the metal part 11 is relatively far from other parts, which can achieve a wider range of cooling. The remaining cooling mechanisms 8 are equally distributed, so that the cooling mechanisms 8 are evenly arranged on the surface of the metal part 11, thereby achieving a full surface coverage effect.

[0045] The cooling mechanism 8 includes hollow support rollers 81, rotatably arranged at equal intervals between two arc-shaped supports 6 along the arc direction of the arc-shaped support 6, forming an arc shape. The hollow support rollers 81 are divided into left and right ends at their centerline. The upper end of the left end, which is equally spaced around a first oblique hole 84, slopes towards the right end. The upper end of the right end, which is equally spaced around a second oblique hole 86, slopes towards the left end. This slope angle can be set to 20-60 degrees with the horizontal line as the baseline (e.g., ...). Figure 6 As shown), the extension lines of the first oblique hole 84 and the second oblique hole 86 intersect, thereby tilting the atomizing heads 85 inside the first oblique hole 84 and the second oblique hole 86. Preferably, there is an angle of 22.5 to 56.3 degrees between the atomizing head 85 and the metal part 11; more preferably, the angle between the atomizing head 85 and the metal part 11 is 35 to 46.5 degrees. The multiple atomizing heads 85 arranged at both ends of the hollow support roller 81 spray at the same angle and are spaced apart from each other. This distance is set according to the actual situation and can be 0.5 cm, 1 cm, etc. The sprayed water mist has a certain dispersion surface, so the multiple sprayed water mists can be linearly arrayed and superimposed on both ends of the metal part 11 to achieve the end face coverage effect. The edges of the spray ranges of the two atomizing heads 85 overlap, and the multiple atomizing heads 85 spray at the same angle have a certain dispersion surface. The atomizing heads 85 are arranged in sequence to achieve full coverage of the surface of the metal part 11. The atomizing heads 85 that are not blocked by the surface of the metal part 11 will spray low-temperature liquid onto both ends of the metal part 11, thereby achieving quenching. The angle of the atomizing heads 85 can affect the quenching effect and coverage effect on both ends of the metal part 11. The spraying pressure of the atomizing heads 85 can also be adjusted according to the diameter of the metal part 11, thereby changing the spraying distance. For metal parts 11 with smaller diameters, the spraying pressure of the atomizing heads 85 is reduced to ensure that the water mist can fully cover the end face of the metal part 11. Conversely, for metal parts 11 with larger diameters, the spraying pressure of the atomizing heads 85 is increased to make it spray farther. At the same time, the liquid adheres to the end face of the metal part 11 and flows downward under the action of gravity, which can also improve the quenching effect.

[0046] The head of the atomizing head 85 needs to be 2mm lower than the upper opening of the first inclined hole 84 and the second inclined hole 86. This is to prevent the metal part 11 from being damaged by force when it rolls on the surface of the hollow support roller 81. When the atomizing head 85 is installed in the inner cavity of the first inclined hole 84 and the second inclined hole 86, a 2mm gap can also be reserved to prevent the thermal expansion and contraction of the hollow support roller 81 from squeezing the atomizing head 85. All of the above settings are to increase the service life of the atomizing head 85.

[0047] The connecting end of the atomizing head 85 is located in the inner cavity of the hollow support roller 81, and is installed on the inner wall of the hollow support roller 81 with screws, or multiple atomizing heads 85 are uniformly installed on the bracket installed in the inner cavity of the hollow support roller 81, thus facilitating installation. Each atomizing head 85 is equipped with a water inlet and an air inlet. The water inlets of the multiple atomizing heads 85 are connected in parallel and fixed to the output pipe of the first air rotating slip ring 7 with clamps. The air inlets of the multiple atomizing heads 85 are connected in parallel and fixed to the output pipe of the second air rotating slip ring 10 with clamps, thereby enabling the delivery of cold air and cold water to the atomizing head 85, and spraying out low-temperature liquid accompanied by low-temperature air. When connected in parallel, a T-connector is required to connect the multiple atomizing heads 85 to each other. It should be noted that this atomizing head 85 adopts the principle of siphon, that is, the high-pressure gas flow at high speed will drive the liquid to be sprayed out from the hole. This spraying method achieves both air cooling and liquid cooling. The combination of the two achieves a better quenching effect.

[0048] To facilitate the installation of the atomizing head 85, the hollow support roller 81 can be set into two semicircles. After the atomizing head 85 is installed, it is spliced ​​together. It should be noted that the surface splicing seam should not be too large. Therefore, a high splicing accuracy is required, preferably 1-2mm.

[0049] Several hollow support rollers 81 need to protrude from the upper end face of the two arc-shaped brackets 6. The height of the protrusion is not limited, and is mainly set according to the diameter and width of the first air rotary slip ring 7 and the second air rotary slip ring 10. That is to say, the highest point of the first air rotary slip ring 7 and the second air rotary slip ring 10 needs to be lower than the highest point of the hollow support rollers 81, so that when there are metal parts 11 on the surface of the hollow support rollers 81, they will not interfere with the housing or pipe of the first air rotary slip ring 7 and the second air rotary slip ring 10.

[0050] Several hollow support rollers 81 have metal parts 11 to be quenched placed on their upper ends. Metal parts 11 that are too long or too short can be placed on the hollow support rollers 81. In order to quench the metal parts 11 from all directions, the metal parts 11 can be pushed to slide on the surface of the hollow support rollers 81 by a pushing mechanism, so that the atomizing head 85 on the surface of the hollow support rollers 81 can spray quenching liquid on both ends of the metal parts 11, thereby quenching the metal parts 11 as a whole.

[0051] It also includes a drive shaft 82 welded to both ends of the hollow support roller 81 and movably passing through the arc-shaped bracket 6. The drive shaft 82 can also be set into two semicircles along with the hollow support roller 81. The drive shaft 82 is provided with a cavity, through which the transmission pipe can pass and also serves to protect the pipe. The two drive shafts 82 are respectively fixed to the rotating ends of their respective second air rotary slip ring 10 and first air rotary slip ring 7 by flanges and bolts, so that the gas and liquid transmission pipes are directly connected to the pipes at the rotating ends of the second air rotary slip ring 10 and the first air rotary slip ring 7 through the inner cavity of the drive shaft 82.

[0052] The left end of the hollow support roller 81 is fixed with a second air rotating slip ring 10 for supplying cold water to the atomizing head 85 by screws, and the right end of the hollow support roller 81 is fixed with a first air rotating slip ring 7 for supplying cold air to the atomizing head 85 by screws. The arrangement of the two first air rotating slip rings 7 and the second air rotating slip ring 10 allows the hollow support roller 81 to spray gas and liquid while rotating, so that the hollow support roller 81 can rotate normally.

[0053] The support mechanism 9 includes a support plate 91 fixed to the bottom of the wastewater collection tank 1 by anti-rust bolts. The top of the support plate 91 is located between two atomizing heads 85 on the surface of the hollow support roller 81, and a 2mm gap is left between it and the edges of the first inclined hole 84 and the second inclined hole 86. For example, (the first inclined hole 84 and the second inclined hole 86 are collectively referred to as inclined holes). If the distance between the two inclined holes is set to 40mm, then the 2mm reserved between the support plate 91 and the first inclined hole 84 and the second inclined hole 86 is removed. That is to say, the width of the support plate 91 should be set to 36mm.

[0054] The upper end of the support plate 91 has arc-shaped grooves 94 on both sides, with an arc greater than that of the hollow support roller 81. The center of the arc-shaped grooves 94 coincides with the axis of the hollow support roller 81, and the radius of the arc-shaped grooves 94 is greater than the radius of the outer ring of the hollow support roller 81. Therefore, the hollow support roller 81 can be placed in the arc-shaped grooves 94. A movable groove 92 is provided in the middle of the two arc-shaped grooves 94. Guide rollers 93 are rotatably arranged on both sides of the inner wall of the movable groove 92 through a rotating shaft. Several guide rollers 93 are arranged along the arc of the arc-shaped grooves 94 to form an arc and closely adhere to the surface of the hollow support roller 81 to achieve the support effect.

[0055] Wastewater collection tank 1 is fixedly provided with a first driving mechanism 2 on one side of the axial direction of metal part 11 to drive the metal part 11 to rotate. The lower end of the first driving mechanism 2 can be provided with a linear driving mechanism, which can drive the first driving mechanism 2 to move laterally in a linear manner, thereby driving the metal part 11 to move, so that the quenching is more comprehensive (not shown in the figure). The output end of the first driving mechanism 2 is fixedly provided with a rotating clamping mechanism 3 for clamping the metal part 11. The jaws of the rotating clamping mechanism 3 have the ability to expand and shrink, so that they can clamp both hollow tubes and solid tubes.

[0056] like Figure 4 As shown, each side of the arc-shaped bracket 6 has through holes 62 corresponding to the number of cooling mechanisms 8. The through holes 62 of the two arc-shaped brackets 6 are opposite each other. The through holes 62 are interference-fitted with the outer ring of the bearing 83. Each drive shaft 82 passes through the middle of the fixed bearing 83 and extends to the outside.

[0057] like Figure 3 , 4 As shown, the outer sides of the two arc-shaped brackets 6 are fixed with screws to mounting brackets 63 for fixing the second air rotating slip ring 10 and the fixed end of the first air rotating slip ring 7. The mounting brackets 63 are L-shaped. The lower middle part of the two arc-shaped brackets 6 is integrally formed with the support frame 61. The support frame 61 is fixed to the bottom of the inner cavity of the wastewater collection tank 1 with anti-rust bolts. The size of the wastewater collection tank 1 is larger than the width of the arc-shaped brackets 6 and the axial distance of the cooling mechanism 8. Side plates are provided on both sides of the wastewater collection tank 1. The side plates are rectangular and their height is 1m higher than the upper end of the arc-shaped brackets 6 to achieve the effect of wrapping.

[0058] like Figure 1 , 2 As shown, a chiller 4 for cooling liquid is fixed on the ground on one side of the wastewater collection tank 1. The chiller 4 is equipped with a cooling end. A water pumping mechanism 13 is fixed on one side of the chiller 4. The water pumping mechanism 13 includes a water pump, water pipes, and a water storage tank. The connection between the chiller 4 and the water pumping mechanism 13 is a conventional connection, which will not be described in detail. The cooling end of the chiller 4 cools the water in the water storage tank of the water pumping mechanism 13. A cooler 5 is fixed on the other side of the wastewater collection tank 1 at the corresponding position of the chiller 4. The cooler 5 can cool the air. The air supply end of the cooler 5 and the water supply end of the water pumping mechanism 13 are respectively fixed to the input ends of two water distributors 12 by clamps. The output ends of the two water distributors 12 are respectively fixed to the water inlet end and the air inlet end of the atomizing head 85 by clamps.

[0059] Example 2

[0060] The difference from Embodiment 1 is that the cooling mechanism 8 can be driven to rotate by the second drive mechanism 16 on one side of the arc-shaped bracket 6, which can drive the metal part 11 to rotate actively, and is used for quenching shorter metal parts 11.

[0061] like Figure 9 As shown, an external gear ring 14 is fixed around the hollow support roller 81 near the side of the arc-shaped bracket 6. The second drive mechanism 16 includes a mounting base 162 screwed onto the surface of the arc-shaped bracket 6. A motor 163 is fixed to the upper end of the mounting base 162 by screws. The output shaft of the motor 163 is keyed with a drive gear 161 that meshes with the external gear ring 14. Its installation position is as shown. Figure 9As shown, a transition gear 15 meshes between every two external gear rings 14. The middle part of the transition gear 15 is movably inserted into the surface of the arc-shaped bracket 6 through a rotating shaft 83 and a bearing, thereby achieving fixation and transmission.

[0062] Using the above solution: the surface of the motor 163 needs to be equipped with a heat insulation cover and a heat dissipation device to help the motor 163 cool down. The drive gear 161, transition gear 15 and outer gear ring 14 are all made of high-temperature resistant tungsten metal. The transition gear 15 needs to be set according to the needs. That is to say, the size of the transition gear 15 is different. The surface of the arc bracket 6 is provided with multiple insertion holes. Different transition gears 15 are inserted as needed to change the rotation direction of the hollow support roller 81.

[0063] The components of this invention, including the first drive mechanism 2, the rotating clamp mechanism 3, the refrigeration unit 4, the air conditioner 5, the first air rotating slip ring 7, the second air rotating slip ring 10, the bearing 83, the water distributor 12, the pumping mechanism 13, and the motor 163, are existing technologies, and their structural principles will not be elaborated further. The first air rotating slip ring 7 and the second air rotating slip ring 10 are set to the MK81 series from Mervelon, capable of 8 inlets and 8 outlets or higher. The bearing 83 includes an outer ring, an inner ring, and ball bearings. The water distributor 12 can be configured with one inlet and 8 outlets, or 9 outlets, depending on the specific situation. It should be noted that to ensure normal pressure, the inlet flow rate of the water distributor 12 must be greater than the sum of its outlet flow rates. Except for the connecting pipes, all mechanisms used in this invention are made of high-temperature resistant metal materials, which can be selected based on manufacturing costs. This invention also includes switches, external power grids, microcomputers, and controllers, which are not considered core technologies and will not be detailed further.

[0064] If the exhaust pressure of the air conditioner 5 is insufficient, an external air pump can be connected to pump high-pressure gas into the atomizing head 85 through the air pump. The atomizing head 85 is preferably an atomizing siphon nozzle.

[0065] Working principle and usage process of this invention:

[0066] This invention consists of two steps: Step 1, quenching is performed on metal parts 11 of moderate or relatively long length; Step 2, quenching is performed on shorter metal parts 11, as detailed below:

[0067] Step 1: Place a metal part 11, slightly smaller than the length of the hollow support roller 81, into the arc-shaped bracket 6 via a transport device so that it contacts the hollow support roller 81 and is supported by the hollow support roller 81. After placement, the linear drive mechanism drives the first drive mechanism 2 to move. At the same time, the jaws of the rotating clamp mechanism 3 open, so that the metal part 11 is located in the jaws. Then, the jaws clamp the metal part 11. Subsequently, the first drive mechanism 2 drives the rotating clamp mechanism 3 to rotate, thereby causing the metal part 11 to rotate on the upper end of the hollow support roller 81, and at the same time, causing the hollow support roller 81 to rotate.

[0068] When the switch is turned on, the power grid supplies power to the electrical equipment of this device via wires. The chiller 4, air cooler 5, and water pump mechanism 13 operate simultaneously. The chiller 4 cools the cooling water inside the water storage tank of the water pump mechanism 13. Then, the water pump of the water pump mechanism 13 transports the water through pipes to the water distributor 12. Each outlet pipe of the water distributor 12 delivers the cooling water to the inlet of each atomizing head 85. Simultaneously, the air cooled by the air cooler 5 is delivered to the water distributor 12 through the air outlet pipe. Each outlet pipe of the water distributor 12 delivers high-pressure air to the inlet of each atomizing head 85. The atomizing head 85 then delivers the high-pressure air... Compressed air and cooling water are mixed and sprayed out to form a mist. The atomizing head 85 sprays the cold air and atomized water onto the surface of the metal part 11. The spray angle of the atomizing head 85 can be set to 30 degrees to ensure both cooling range and atomization amount. Multiple atomizing heads 85 spray surfaces are connected to cover the surface of the metal part 11. The metal part 11 will contact the hollow support roller 81 at the lower end of the arc-shaped bracket 6. Therefore, the cold air and water will be concentrated at a small point. To reduce uneven cooling, the rotation speed of the metal part 11 should be set between 180-300 r / min, or it can be set according to the surface area of ​​the metal part 11.

[0069] If the length of the metal part 11 is less than the length of the hollow support roller 81, the atomizing head 85 is set with an inclined angle. Therefore, the atomizing heads 85 on both sides of the metal part 11 will spray air-cooled spray on both ends of the metal part 11, thereby achieving the quenching effect. In order to better change the spray range of the atomizing head 85, the atomizing head 85 with a variable spray range is used, which can better cover both ends of the metal part 11 and improve the quenching effect.

[0070] If the length of the metal part 11 is longer than the length of the hollow support roller 81, then a linear drive mechanism is needed to drive the metal part 11 to move back and forth laterally on the surface of the hollow support roller 81 so that one end of the metal part 11 can be located within the spray range of the atomizing head 85, thereby enabling the two ends to be quenched alternately.

[0071] Step 2: When the metal part 11 to be quenched is too short to be rotated using the rotating clamp mechanism 3, simply place the metal part 11 in the arc-shaped bracket 6. The quenching process follows the steps in "Step 1". The motor 163 is powered on, and the output shaft of the motor 163 drives the drive gear 161 to rotate, which in turn drives the outer gear ring 14 to rotate, which in turn drives the hollow support roller 81 directly connected to the drive gear 161 to rotate. The outer gear ring 14 of the hollow support roller 81 drives the transition gear 15 to rotate, which in turn drives the other hollow support rollers 81 to rotate, which in turn drives the metal part 11 to rotate. It should be noted that the number of hollow support rollers 81 in contact with the metal part 11 will vary depending on the diameter of the metal part 11, such as 2 or 3. Therefore, before quenching, it is necessary to splice and combine the transition gears 15 of different sizes and insert them into the insertion holes of the arc-shaped bracket 6 so that the hollow support rollers 81 in contact with the metal part 11 rotate in the same direction, thereby driving the metal part 11 to rotate smoothly and achieve the quenching effect.

[0072] In summary, the present invention can perform quenching and cooling of metal parts 11 in all directions, and can also perform quenching and cooling of metal parts 11 of different sizes, thereby reducing the cost of use and improving work efficiency.
