Abstract
Description
Technical Field
[0001] This disclosure relates to the field of manufacturing tracked components for engineering machinery, and in particular to a quenching device and quenching method for tracked chassis components. Background Technology
[0002] Ultra-heavy tracked chassis have a large overall weight (generally over 300 tons for the main unit), high safety requirements, and complex structures for the track shoes, idlers, and drive wheels. They are typically cast, while the track rollers and carrier rollers are forged. To meet the operating conditions of the main unit, the product requires high strength and impact resistance, as well as high surface hardness and wear resistance.
[0003] Ultra-large tonnage track and wheel products have large dimensions. The largest single component of the track or wheel product weighs more than 6 tons. The requirements for quenching areas and hardened layer depth vary for different products. For example, the track tread, teeth and pin holes, the track roller tread (or outer circle), the outer circle and inner side of the idler wheel, the tooth root, tooth surface (pulled tooth) and outer circle of the drive wheel all require induction hardening. The hardened layer depth is generally required to be more than 20mm. To complete the quenching heat treatment of the above parts, different inductor structures, quenching methods and electric heating parameters are required.
[0004] In the prior art known to the inventor, the industry generally uses two to three induction hardening equipment, and completes the hardening treatment of each position of the track and wheel by frequently changing the inductor and using different positioning fixtures. This results in large equipment investment, low heat treatment production efficiency, poor heat treatment process stability, and great difficulty in lifting and turning the workpiece.

[0036] Select the appropriate quenching method and the appropriate inductor based on the object being quenched.
[0037] The object to be quenched is loaded, and the limiting mechanism limits the object to be quenched.
[0038] The orientation of the quenching object is adjusted by a rotating mechanism and / or a flipping mechanism, so that different inductors heat different parts of the quenching object.
[0039] After the quenching process is completed, the rotating mechanism and / or flipping mechanism are used to adjust the quenched object to a horizontal state.
[0040] The limiting mechanism is released from its position on the quenched object, allowing the material to be unloaded.
[0041] In some embodiments, the tracked chassis component quenching device further includes a translation mechanism configured to drive a limiting mechanism to move along a first direction between the loading / unloading station and the quenching station; wherein...
[0042] After the limiting mechanism limits the quenching object, the quenching method further includes: driving the limiting mechanism to translate along a third direction to the quenching station using a translation mechanism; and / or

[0060] After the first outer circle sensor reaches the heating termination position, the first outer circle sensor stops heating, and the first outer circle sensor and the water sprayer move upward quickly by a preset distance. The water sprayer sprays for a preset time and then ends the quenching of the lower half of the wheel body.

[0103] First, this disclosure provides a quenching device for tracked chassis components, hereinafter referred to as "quenching device". In some illustrative embodiments, such as... Figures 1 to 13 As shown, the track undercarriage component quenching device is used to quench the object to be quenched, which includes the track plate 101 and the wheel body. The quenching device includes:
[0104] The frame includes two columns 1 extending along a first direction z;
[0105] The fixed base 2 is movably mounted on the column 1 along the first direction z. The fixed base 2 includes a plurality of cross slides 21.
[0106] Multiple sensors 4 are movably disposed on the cross slide 21 along the second direction y and the third direction x, and are arranged in a one-to-one correspondence with the multiple cross slides 21. The sensors 4 are configured to heat the quenched object. The second direction y is perpendicular to the first direction z, and the third direction x is perpendicular to the first direction z and the second direction y.
[0107] The limiting mechanism 6 is located on the side of the sensor 4 away from the cross slide table 21 along the first direction z. It includes a clamping device 61, a spindle mounting seat 62 and a spindle. The clamping device 61 is used to limit the track plate 101. The spindle mounting seat 62 is used to install the spindle. The outer diameter of the spindle matches the inner diameter of the wheel body to limit the wheel body.
[0108] Rotating mechanism 7, located at the bottom of limiting mechanism 6, is configured to drive limiting mechanism 6 to rotate around a preset center line, the preset center line extending along a first direction z; and
[0109] The flipping mechanism 8 is located on both sides of the limiting mechanism 6 along the second direction y, and is configured to drive the limiting mechanism 6 to rotate around the flipping axis, which extends along the second direction y.
[0110] Specifically, the frame can be a double-column gantry structure. Specifically, multiple sensors 4 can be arranged side by side on the cross slide 21 of the fixed base 2. The sensors 4 can move with the cross slide 21 in two directions: front-back (third direction x) and left-right (second direction y). The fixed base 2 as a whole can move up and down (first direction z) with the gantry columns. Through the above design, multiple sensors 4 can be independently servo-moved in three-dimensional directions.
[0111] Specifically, based on the principle of electromagnetic induction, when alternating current is applied to inductor 4, induced eddy currents are generated on the surface of the object being quenched, thereby achieving heating. Specifically, inductor 4 can control parameters such as heating power output, heating time, and heating speed. Optionally, inductor 4 can be made of pure copper.
[0112] Specifically, the rotating mechanism 7 can drive the limiting mechanism 6 to rotate at a uniform speed and / or index around a preset center line to adapt to the quenching requirements of different quenching objects. Optionally, the rotating mechanism 7 can be a rotary servo motor. Specifically, the flipping mechanism 8 can drive the limiting mechanism 6 to rotate around a flipping axis to achieve functions such as flipping to horizontal, vertical, or a certain tilt angle. Specifically, the flipping mechanism 8 may include a flipping shaft; optionally, the rotating mechanism 7 and the flipping mechanism 8 can be integrated into a design. Specifically, the wheel body has a rotating structure and can be horizontally limited on the mandrel of the limiting mechanism. The diameter of the mandrel is designed separately according to the inner hole size of the wheel body. Specifically, the mandrel of the limiting mechanism can achieve rapid positioning of the wheel body. Specifically, to improve the uniformity of heating temperature, the wheel body needs to rotate during the heat treatment process.
[0113] Specifically, multiple sensors 4, in conjunction with the rotating mechanism 7 and the flipping mechanism 8, enable rapid switching between induction hardening of different heat treatment zones without the need to replace the sensors. Optionally, the wheel body can be a support wheel 102, a guide wheel 103, or a drive wheel 104, etc. Correspondingly, the mandrel can include a support wheel mandrel, a guide wheel mandrel, or a drive wheel mandrel, etc. The support wheel mandrel, guide wheel mandrel, and drive wheel mandrel can be selectively mounted on the mandrel mounting base 62, and the outer diameter of the support wheel mandrel, guide wheel mandrel, and drive wheel mandrel matches the inner diameter of the support wheel 102, guide wheel 103, and drive wheel 104, respectively.
[0114] Specifically, the track undercarriage component quenching device can quench multiple quenching positions of the object sequentially or simultaneously. Optionally, the quenching positions can be the pull teeth (A1; A2) of the track plate 101, the tread surfaces (A3-A6) of the track plate 101, the inner holes (A7-A12) of the track plate 101, the outer circle of the track roller 102, the outer circle and inner side surface of the guide wheel 103, the pull teeth and outer circle of the drive wheel 104, etc. Specifically, the first tread surface A3 and the third tread surface A5 of the track plate 101, because they are close to the pull teeth, can also be referred to as the inner side surface of the pull teeth.
[0115] The limiting mechanism of the quenching device in this embodiment can quickly limit the track plate and the wheel body. Only one device is needed to complete the quenching of each position of the track plate and the wheel body. Moreover, through rotation, flipping and other actions, it can complete the induction quenching of different heat treatment areas in one go, which can improve the quenching quality and quenching efficiency.
[0116] The track chassis component quenching device of this embodiment, through the cooperation of multiple sensors with a rotating mechanism and a flipping mechanism, can be compatible with quenching treatment of track plates and wheels. It does not require frequent replacement of sensors or the use of different positioning fixtures. The equipment has low investment cost and small space occupation. The workpiece rotation and flipping operation is easy, which can improve quenching safety, heat treatment production efficiency and heat treatment process stability, and improve the quenching quality of the quenched object.
[0117] In some embodiments, such as Figure 1 and Figure 2 As shown, the tracked chassis component quenching device also includes:
[0118] The translation mechanism 9 is located on both sides of the flipping mechanism 8 along the second direction y, and is configured to drive the limiting mechanism 6 to move between the loading / unloading station and the quenching station along the first direction z.
[0119] Specifically, the translation mechanism 9 may include a moving guide rail and a servo motor for driving the limiting mechanism 6 to move the quenching object laterally. Optionally, the translation mechanism 9 may also drive the limiting mechanism 6 to move in other directions within the vertical or horizontal plane. Optionally, the translation mechanism 9 may also be located at the bottom of the rotating mechanism 7 or in other spaces of the quenching device capable of driving the limiting mechanism 6 to translate. Specifically, the quenching station corresponds to the movement area of the multiple sensors 4, while the loading and unloading station is located outside the movement area of the multiple sensors 4.
[0120] The quenching device in this embodiment, by setting a translation mechanism, can drive the quenching object to move between the loading / unloading station and the quenching station, which can facilitate loading / unloading operations and meet the heat treatment requirements of products of different heights.
[0121] In some embodiments, such as Figures 1 to 3 As shown, the clamping device 61 includes a first plate 611 extending along a second direction y and a second plate 612 extending along a third direction x. The first plate 611 has clamping members 613 movable along the second direction y on both sides located at the center. The second plate 612 has clamping members 613 movable along the third direction x on both sides located at the center. The clamping members 613 are configured to clamp the track plate by moving toward the center of the clamping device 61.
[0122] Specifically, the clamping device 61 is a cross-shaped bidirectional automatic centering clamping device. Optionally, the clamping component 613 can be driven by an asynchronous geared servo motor and a trapezoidal screw drive. Specifically, the clamping device 61 can realize automatic alignment and clamping fixation of the track plate 101 before heat treatment. Specifically, after the track plate 101 is loaded, the alignment and clamping function of the clamping device 61 can ensure that the gap between each track plate 101 and the sensor 4 is consistent during induction heating.
[0123] The quenching device in this embodiment aligns and clamps the track plates using a clamping device. This ensures that each track plate has the same gap with the sensor during induction heating, and also ensures the stability and safety of the track plates during rotational motion, which is beneficial for improving quenching quality and efficiency.
[0124] In some embodiments, such as Figures 1 to 3 As shown, the mandrel mounting base 62 is located at the center of the clamping device 61, and the center of the clamping device 61 is located on a preset center line.
[0125] This embodiment sets the centers of the mandrel mounting base and the clamping device on a preset center line, which makes the position of the quenching object stable and controllable during the rotation driven by the rotating mechanism. This helps to control the heating gap and improve the quenching quality and quenching safety.
[0126] In some embodiments, as shown in Figures 6 to 7 Figure 13 As shown, the wheel body includes at least one of a support wheel 102, a guide wheel 103, or a drive wheel 104, and the spindle includes at least one of a support wheel spindle, a guide wheel spindle, or a drive wheel spindle.
[0127] Specifically, the support roller spindle, guide roller spindle, and drive roller spindle can be selectively mounted on the spindle mounting base 62 according to processing needs. The outer diameters of the support roller spindle, guide roller spindle, and drive roller spindle are matched with the inner diameters of the support roller 102, guide roller 103, and drive roller 104, respectively, to achieve rapid positioning of the wheel body.
[0128] The quenching device in this embodiment can quickly and accurately position different wheels by switching mandrels, which helps to maintain a stable heating gap during the movement of the limiting mechanism and improves quenching quality and efficiency.
[0129] In some embodiments, a plurality of sensors 4 are detachably mounted on a plurality of cross slides 21.
[0130] Specifically, by setting multiple sensors 4 detachably mounted on the cross slide 21, the quenching device can perform quenching heat treatment on various quenching objects, while simultaneously optimizing the number of sensors and reducing costs by switching the corresponding sensors. For example, if a batch of quenching objects consists of track plates 101 and support rollers, three types of sensors can be set for heating three types of track plate quenching positions (tooth extraction, tread surface, and inner hole). After the track plates are quenched, one of the sensors can be replaced with the first outer circle sensor to continue induction heating of the support rollers. In this case, the need for four or more types of sensors can be avoided.
[0131] The quenching apparatus of this embodiment is detachably mounted on the cross slide by the sensor, which can optimize the number of sensors and reduce the production cost of the quenching apparatus while maintaining stable performance.
[0132] In some embodiments, such as Figures 1 to 13 As shown, the multiple sensors 4 include:
[0133] The first tooth extraction sensor 41, the tread surface sensor 42, and the inner hole sensor 43 are used to heat the tooth extraction, tread surface, and inner hole of the track plate 101, respectively; and / or
[0134] The first outer circle sensor 44 is used to heat the outer circle of the support roller 102; and / or
[0135] The second outer circle sensor 45 is used to heat the outer circle of the guide wheel 103; and / or
[0136] The second tooth extraction sensor 46 and the third outer circle sensor 47 are used to heat the tooth extraction and outer circle of the drive wheel 104, respectively.
[0137] Specifically, the quenching of the tread surface of the track plate 101 can be completed by two scanning heating and cooling by the tread surface sensor 42, and the quenching of the inner hole of the track plate 101 can also be completed by a scanning quenching process. More specifically, before heat treatment of the track plate 101, a first tooth extraction sensor 41, a tread surface sensor 42, an inner hole sensor 43, and a water sprayer 5 can be installed. The sensors 4 and the water sprayer 5 can be arranged adjacent to each other, and the sensors and water sprayers can be automatically switched according to different heat treatment positions during the quenching heat treatment process.
[0138] Specifically, the outer diameter inductor can be fixed to one side of the wheel body, and the wheel body can be rotated by the rotating mechanism 7 to achieve uniform heating of the outer diameter and inner surface of the wheel body. Optionally, multiple inductors 4 can be detached, which can reduce the production cost of the quenching device.
[0139] The quenching device in this embodiment uses different corresponding inductors to perform induction heating on the track plates and wheels, which is compatible with the quenching treatment of track plates and wheels. It can complete induction quenching of different heat treatment areas without changing the inductors or with only a few inductors, thereby improving quenching efficiency and quenching quality.
[0140] In some embodiments, such as Figures 8 to 13 As shown, the first outer circle sensor 44 is adapted to the outer circle of the support roller 102 and is spaced at a first preset distance from the outer circle of the support roller 102; and / or the second outer circle sensor 45 covers the outer circle and inner side surface of the guide roller 103 and is spaced at a second preset distance from the outer circle and inner side surface of the guide roller 103; and / or the third outer circle sensor 47 covers the outer circle of the drive wheel 104 and is spaced at a third preset distance from the outer circle of the drive wheel 104.
[0141] Specifically, the first preset distance, the second preset distance, and the third preset distance constitute the induction heating gap. Optionally, the first preset distance can be 3mm, and / or the second preset distance can be 2.5mm, and / or the third preset distance can be 3mm.
[0142] The quenching device in this embodiment can improve quenching efficiency and quenching quality by setting different outer circle inductors to adapt to the quenching positions of different wheels.
[0143] In some embodiments, such as Figures 1 to 13 As shown, the tracked chassis component quenching device also includes:
[0144] Multiple transformers 3 are movably connected to the cross slides 21 along the second direction y and the third direction x and extend downwards, and are arranged one-to-one with the multiple cross slides 21. The multiple transformers are used to install sensors 4 one-to-one.
[0145] Multiple water sprayers 5 are installed one-to-one with the transformer 3.
[0146] Specifically, transformer 3 can be connected to an alternating power supply. For example, the quenching device can be configured with an IGBT 400kW / 1~6kHz power supply and three independent load transformers. The three transformers 3 are installed side by side on the three cross slides 21 of the fixed base 2. The transformers 3 can be individually adjusted in terms of turns ratio and capacitance according to different frequency requirements. By switching the switch, the output of different power, frequency and other electrical parameters can be quickly switched. The inductor 4 can be replaced and the induction quenching of different heat treatment areas can be quickly switched at one time.
[0147] Specifically, the transformer 3, together with the gantry column 1 and the cross slide 21 at the bottom of the transformer, enables the three-dimensional movement of the inductor 4 and the water sprayer 5. Specifically, the water sprayer 5 and the inductor 4 are independently configured. The inductor 4 controls parameters such as heating power output, heating time, and heating speed, while the water sprayer 5 controls parameters such as water flow rate, water spray time, water spray position, and cooling time. More specifically, because the quenched object needs to be cooled immediately after the inductor 4 finishes heating, the inductor 4 and the water sprayer 5 are positioned adjacent to or near each other.
[0148] The quenching apparatus of this embodiment improves quenching efficiency and quenching quality by adjusting the power and frequency of inductor heating through a transformer and by adjusting the parameters of the cooling process through a water sprayer.
[0149] In some embodiments, such as Figure 8 and Figure 12 As shown, in the rotation direction of the guide wheel 103, the water sprayer 5 and the second outer circle sensor 45 provided on the upper wheel body 131 of the guide wheel are located behind the water sprayer 5 and the second outer circle sensor 45 provided on the lower wheel body 132 of the guide wheel; and / or in the rotation direction of the drive wheel 104, the water sprayer 5 and the third outer circle sensor 47 provided on the upper wheel body 141 of the drive wheel are located behind the water sprayer 5 and the third outer circle sensor 47 provided on the lower wheel body 142 of the drive wheel.
[0150] Specifically, during heat treatment of the guide wheel 103 and / or drive wheel 104, the inductor and water sprayer 5 remain stationary, while the wheel rotates at a constant speed in the direction of the arrow shown in the figure. Specifically, due to the rotation of the wheel, the water sprayer of the upper wheel is positioned behind the inductor and water sprayer of the lower wheel in the direction of rotation. This allows the cooling water from the upper wheel's water sprayer to flow diagonally downwards, bypassing the inductor and water sprayer of the lower wheel, i.e., the cooling water from the upper wheel flows to the lower left in the attached figure, thereby preventing the cooling water from the upper wheel from interfering with the quenching heat treatment of the lower wheel.
[0151] Specifically, the outer diameter inductor simultaneously induction heats the quenching portions of the upper and lower wheel bodies. More specifically, a single scan by the second outer diameter inductor 45 and the water sprayer 5 can simultaneously complete the quenching of the outer diameter and inner surface of the upper wheel body 131 and the lower wheel body 132 of the guide wheel; a single scan by the third outer diameter inductor 47 and the water sprayer 5 can simultaneously complete the quenching of the outer diameter of the upper wheel body 141 and the lower wheel body 142 of the drive wheel. Optionally, the inductor located on the upper wheel body is offset from the inductor located on the lower wheel body by 30-40 mm.
[0152] The arrangement of the water sprayer and sensor in this embodiment can prevent the cooling water of the water sprayer on the upper wheel body from affecting the water sprayer and sensor on the lower wheel body, thereby improving the quenching quality.
[0153] In some embodiments, there are three sensors 4, namely a first tooth extraction sensor 41, a tread sensor 42, and an inner hole sensor 43.
[0154] Specifically, setting three sensors 4 can fully meet the induction heating requirements of each quenching position of the track plate 101, thereby achieving the heating of different quenching positions of the track plate 101 in one go without replacing the sensors 4; when the wheel body needs to be quenched, the corresponding sensors 4 can be replaced as needed, thereby reducing the production cost of the quenching device.
[0155] The quenching device of this embodiment can perform induction heating on different parts of the track plate through the first tooth extraction sensor, the tread surface sensor and the inner hole sensor. It does not require frequent replacement of sensors, has low equipment investment cost and occupies little space, and can improve the heat treatment production efficiency and heat treatment process stability, and improve the quenching quality of the quenched object.
[0156] Secondly, this disclosure also provides a quenching method for the track chassis component quenching device based on the above embodiments, including:
[0157] Select the corresponding quenching method according to the object to be quenched, and select the corresponding sensor 4 according to the object to be quenched;
[0158] The object to be quenched is loaded, and the limiting mechanism 6 limits the object to be quenched.
[0159] The orientation of the quenching object is adjusted by the rotating mechanism 7 and / or the flipping mechanism 8, so that different inductors 4 heat different parts of the quenching object.
[0160] After the quenching process is completed, the rotating mechanism 7 and / or the flipping mechanism 8 are used to adjust the quenched object to a horizontal state.
[0161] Release the limiting mechanism 6 from the quenching object and unload the material.
[0162] Specifically, the process of selecting and installing the corresponding inductor 4 may also include installing a water sprayer 5 and adjusting the turns ratio and capacitor quantity of the transformer 3 according to the quenching process requirements of the object to be quenched. Optionally, after heating different parts of the object to be quenched, water spraying through the water sprayer 5 may be used for cooling. Optionally, during the quenching process of the wheel body, the rotating mechanism 7 can drive the wheel body to rotate at a uniform speed, which can improve the uniformity of heating temperature and the quenching quality.
[0163] The quenching method of this embodiment limits the quenching object by using a limiting mechanism, and completes induction quenching of different heat treatment areas in one go by rotating, flipping and other actions. It does not require frequent replacement of inductors and use of different positioning fixtures, which can improve quenching quality and quenching efficiency. At the same time, it can improve heat treatment production efficiency and heat treatment process stability, and improve the quenching quality of the quenching object.
[0164] In some embodiments, the tracked chassis component quenching device further includes a translation mechanism 9, configured to drive the limiting mechanism 6 to move along a first direction z between the loading / unloading station and the quenching station; wherein, after the limiting mechanism 6 limits the quenching object, the quenching method further includes: driving the limiting mechanism 6 to translate along the first direction z to the quenching station by the translation mechanism 9; and / or after the quenching object is reset to a horizontal state, the quenching method further includes: driving the limiting mechanism 6 to translate along the first direction z to the loading / unloading station by the translation mechanism 9.
[0165] Optionally, the translation mechanism 9 can also drive the limiting mechanism 6 to move in other directions within the vertical or horizontal plane. Specifically, the quenching station corresponds to the movement area of the multiple sensors 4, while the loading and unloading station is located outside the movement area of the multiple sensors 4.
[0166] The quenching method in this embodiment drives the limiting mechanism to translate, which can drive the quenching object to move between the loading / unloading station and the quenching station. This facilitates loading / unloading operations and can meet the heat treatment requirements of products of different heights.
[0167] In some embodiments, such as Figures 4A to 5D As shown, the object to be quenched includes track plate 101, and the quenching method includes:
[0168] Place the track plate 101 horizontally with the teeth facing upwards into the clamping device 61, and limit the track plate 101 by the clamping device 61.
[0169] The first tooth extraction sensor 41 is used to quench the first side A1 and the second side A2 of the tooth extraction that are opposite each other along the second direction y.
[0170] The limiting mechanism 6 is rotated 90° around the preset center line by the rotating mechanism 7, so that the tread sensor 42 quenches the first tread A3 and the second tread A4 of the track plate 101.
[0171] The limiting mechanism 6 is rotated 180° around the preset center line by the rotating mechanism 7, so that the tread sensor 42 can quench the third tread A5 and the fourth tread A6 of the track plate 101.
[0172] The limiting mechanism 6 is rotated 90° around the flipping axis by the flipping mechanism 8, and the limiting mechanism 6 is rotated 90° around the preset center line by the rotating mechanism 7, so that the inner hole sensor 43 can quench the first pin hole A7, the second pin hole A8 and the third pin hole A9 of the track plate 101.
[0173] The limiting mechanism 6 is rotated 180° around the preset center line by the rotating mechanism 7, so that the inner hole sensor 43 can quench the fourth pin hole A10, the fifth pin hole A11 and the sixth pin hole A12 of the track plate 101.
[0174] Specifically, before placing the track plate 101 horizontally with the teeth facing upwards into the clamping device 61, the quenching method may also include: sequentially installing the first tooth extraction sensor 41, the tread surface sensor 42, and the inner hole sensor 43 on the transformer 3; installing water sprayers 5 on the transformer 3 one-to-one; and adjusting the turns ratio and the number of capacitors of the transformer 3 according to the quenching process requirements of the track plate 101.
[0175] Specifically, the use of an inductor for quenching is for convenience only; the actual process involves heating the inductor followed by cooling to complete the quenching. Specifically, after the quenching process is completed, the quenching method may further include: adjusting the track plate 101 to a horizontal state using the rotating mechanism 7 and the flipping mechanism 8, releasing the clamping device 61 from its limiting position on the track plate 101, and unloading the track plate.
[0176] The quenching method of this embodiment employs an induction heating process that combines a first tooth extraction sensor, a tread surface sensor, and an inner hole sensor with a rotating mechanism and a flipping mechanism. This process enables induction heating of different parts of the track plate without the need for frequent sensor replacements. The equipment has low investment costs and occupies little space, thereby improving heat treatment production efficiency and process stability, and enhancing the quenching quality of the track plate.
[0177] In some embodiments, the quenching method further includes setting reasonable quenching parameters according to the quenching requirements of different parts of the track plate. For example, the heating power of the first tooth extraction sensor 41 is 150 kW, the heating frequency is 2-3 kHz, the heating gap is 4 mm, the corresponding quenching fluid flow rate of the water sprayer 5 is 260 L / min, and the quenching fluid concentration is 10%-14%; and / or
[0178] The heating power of the tread sensor 42 is 180 kW, the heating frequency is 2–3 kHz, the heating gap is 3 mm, and the scanning heating speed is 90 mm / min. The corresponding quenching fluid flow rate of the water sprayer 5 is 400 L / min, and the quenching fluid concentration is 10%–14%; and / or
[0179] The heating power of the inner hole sensor 43 is 150kw, the heating frequency is 2-3kHz, the heating gap is 2.5mm, the scanning heating speed is 130mm / min, and the corresponding quenching fluid flow rate of the water sprayer 5 is 80L / min, and the quenching fluid concentration is 10%-14%.
[0180] This embodiment sets quenching parameters according to different quenching zones of the track plate, taking into account factors such as sensor type, track plate structure, equipment investment, production efficiency, process stability, and economy, which can improve the quenching quality and quenching efficiency of the track plate.
[0181] In some embodiments, as shown in FIG6, the quenching object includes a wheel body, the wheel body being a support wheel 102, and the quenching method includes:
[0182] A support roller spindle is installed in the spindle mounting seat 62, so that the support roller 102 is horizontally installed on the support roller spindle to limit the position of the support roller 102;
[0183] Move the first outer circle sensor 44 to the starting position of the lower half of the wheel body, and rotate the limiting mechanism 6 around the preset center line through the rotating mechanism 7. Use two preheating and scanning quenching processes to quench the two halves of the support wheel 102 respectively.
[0184] After the quenching process is completed, the support roller mandrel is released from its position on the support roller 102 and the roller is unloaded.
[0185] Specifically, by performing two preheating and scanning quenching processes on the two halves of the support roller, a hardened layer of more than 20 mm and a qualified metallographic structure of martensite grade 3-7 can be obtained. Specifically, the reciprocating preheating method can increase the depth of the hardened layer on the wheel body. Scanning quenching is performed on the two halves of the support roller 102, and the heat treatment method is highly versatile, meeting the induction quenching requirements for all wheels of similar shapes.
[0186] Specifically, the rotating mechanism 7 can make the limiting mechanism 6 rotate at a constant speed around a preset center line to further improve the uniformity of the heating temperature. Specifically, before limiting the support roller 102 by installing the support roller mandrel, the quenching method may also include: installing a first outer circle inductor 44 and a water sprayer 5 on the transformer 3, and adjusting the turns ratio and the number of capacitors of the transformer 3 according to the quenching process requirements of the support roller 102.
[0187] In some embodiments, such as Figure 6A and Figure 6B As shown, the two preheating processes include:
[0188] Move the first outer circle sensor 44 to the heating start position of the lower half of the wheel body and turn on the heating, while the water sprayer 5 is in the off state;
[0189] The first outer circle sensor 44 is moved upward at a set speed to the heating termination position of the lower half of the wheel body, and then moved downward at a set speed to the heating start position, so that the water sprayer 5 remains in the closed state.
[0190] Specifically, the first outer circle sensor 44 moves at a set speed to heat and move uniformly, so as to improve the uniformity of heating temperature.
[0191] In some embodiments, such as Figure 6C and Figure 6D As shown, the scanning quenching process includes:
[0192] Turn on the water sprayer 5, and let the first outer circle sensor 44 continue heating from the heating start position to the heating end position at the set speed;
[0193] After the first outer circle sensor 44 reaches the heating termination position, the first outer circle sensor 44 stops heating, and the first outer circle sensor 44 and the water sprayer 5 move upward quickly by a preset distance. The water sprayer 5 stops quenching the lower half of the wheel body after a preset delay in spraying.
[0194] The first outer circle sensor 44 and the water sprayer 5 are moved to the heating start position of the upper half of the wheel body, so that the quenching process of the lower half of the wheel body is completed to quench the upper half of the wheel body.
[0195] Specifically, the first outer circular sensor 44 can operate at a set speed from the heating start position to the heating end position. Specifically, the preset distance can be 30mm and the preset time can be 3min.
[0196] In some embodiments, the quenching method further includes setting reasonable quenching parameters according to the quenching requirements of the support roller 102. For example, the heating power of the first outer circle inductor 44 is 180 kW, the heating frequency is 2 to 3 kHz, the preheating scanning speed is 120 mm / min, the scanning heating speed is 100 mm / min, the heating gap is 3 mm, and the corresponding quenching liquid flow rate of the water sprayer 5 is 350 L / min, and the quenching liquid concentration is 10% to 14%.
[0197] This implementation method, based on the quenching parameters set in the quenching zone of the support roller, comprehensively considers various factors such as inductor type, support roller structure, equipment investment, production efficiency, process stability, and economy, and can improve the quenching quality and quenching efficiency of the support roller.
[0198] In some embodiments, the object to be quenched includes a wheel body, wherein the wheel body is a guide wheel 103, and the quenching method includes:
[0199] A guide wheel spindle is installed in the spindle mounting seat 62, so that the guide wheel 103 is horizontally installed on the guide wheel spindle to limit the guide wheel 103;
[0200] The limiting mechanism 6 is rotated at a constant speed around the preset center line by the rotating mechanism 7, so that the second outer circle sensor 45 can complete the quenching of the outer circle and the inner side at the same time by scanning and heating once.
[0201] Specifically, before limiting the guide wheel 103 by installing the guide wheel mandrel, the quenching method further includes: installing a second outer diameter sensor 45 and a water sprayer 5 on the transformer 3. The second outer diameter sensor 45 has a contour-following staggered structure. The turns ratio and capacitance of the transformer 3 are adjusted according to the quenching process requirements of the guide wheel 103. Specifically, after the quenching process is completed, the quenching method may also include: releasing the guide wheel mandrel from limiting the guide wheel 103 and unloading it.
[0202] In some embodiments, the quenching method further includes setting reasonable quenching parameters according to the quenching requirements of the guide wheel 103. For example, the heating power of the second outer circle inductor 45 is 120 kW, the heating frequency is 2 to 3 kHz, the scanning heating speed is 90 mm / min, the heating gap is 2.5 mm, the corresponding quenching liquid flow rate of the water sprayer 5 is 260 L / min, and the quenching liquid concentration is 10% to 14%.
[0203] This implementation, based on the quenching parameters set in the quenching zone of the guide wheel, comprehensively considers factors such as inductor type, guide wheel structure, equipment investment, production efficiency, process stability, and economy, and can improve the quenching quality and efficiency of the guide wheel.
[0204] In some embodiments, the object to be quenched includes a wheel body, wherein the wheel body is a drive wheel 104, and the quenching method includes:
[0205] A drive wheel spindle is installed in the spindle mounting seat 62, so that the drive wheel 104 is horizontally installed on the drive wheel spindle to limit the drive wheel 104;
[0206] The limiting mechanism 6 is rotated by the rotating mechanism 7, so that the second tooth extraction sensor 46 sequentially quenches the two sides of all the extraction teeth of the drive wheel 104 that are parallel to the axis of the drive wheel 104.
[0207] After all tooth surfaces have been quenched, the limiting mechanism 6 is rotated at a constant speed around the preset center line by the rotating mechanism 7, so that the third outer circle sensor 47 scans and heats to complete the quenching of the outer circle.
[0208] Specifically, before limiting the drive wheel 104 by installing the drive wheel mandrel, the quenching method may further include: sequentially installing a second tooth-pulling sensor 46 and a third outer diameter sensor 47 on the transformer 3; installing water sprayers 5 on the transformer 3 in a one-to-one correspondence; the third outer diameter sensor 47 having a contour-following staggered structure; and adjusting the turns ratio and capacitor quantity of the transformer 3 according to the quenching process requirements of the drive wheel 104. Specifically, after the quenching process is completed, the quenching method may further include: releasing the drive wheel mandrel from limiting the drive wheel 104 and unloading it.
[0209] Specifically, the second tooth extraction sensor 46 and the first tooth extraction sensor 41 are of different sizes. Specifically, the second tooth extraction sensor 46 advances to wrap around the two sides of the tooth extraction of the drive wheel 104 for heating. After heating is completed, the sensor retracts for spray quenching. Subsequently, the rotating mechanism 7 rotates in increments according to the number of teeth of the drive wheel 104 to continue induction quenching of other tooth surfaces.
[0210] In some embodiments, the quenching method further includes setting reasonable quenching parameters according to the quenching requirements of the drive wheel 104. For example, the heating power of the second tooth extraction sensor 46 is 160 kW, the heating frequency is 2-3 kHz, the heating time is 220 s, the heating gap is 3 mm, the corresponding quenching fluid flow rate of the water sprayer 5 is 240 L / min, and the quenching fluid concentration is 10%-14%; and / or the heating power of the third outer circle sensor 47 is 150 kW, the heating gap is 2.5 mm, the scanning heating speed is 100 mm / min, the corresponding quenching fluid flow rate of the water sprayer 5 is 240 L / min, and the quenching fluid concentration is 10%-14%.
[0211] This implementation, based on the quenching parameters set for the quenching zone of the drive wheel, comprehensively considers factors such as inductor type, drive wheel structure, equipment investment, production efficiency, process stability, and economy, and can improve the quenching quality and efficiency of the drive wheel.
