Technical Field

[0001] The invention relates to the technical field of quenching heat treatment equipment, and in particular to a steel ball quenching heat treatment equipment for steel ball production. Background Art

[0002] As an important mechanical part, steel balls are widely used in bearings, transmission systems and other fields. Their performance directly affects the service life and reliability of equipment. Quenching heat treatment is a key process to improve the hardness and wear resistance of steel balls.

[0003] Traditional steel ball quenching equipment generally includes ordinary box furnaces, pit furnaces, and trolley furnaces. For example, when steel balls are heated in a box furnace, most of the steel balls are heated in a piled state in the box furnace. Due to the contact between the steel balls, the surface of the steel balls is heated unevenly, which affects the hardness and wear resistance of the steel balls. Summary of the invention

[0004] The present application proposes a steel ball quenching heat treatment equipment for steel ball production, which isolates the steel balls for heating and can realize automatic loading and automatic isolation. During the heating process, the steel balls can roll and flip, so that the surface is heated more evenly, thereby improving the hardness and wear resistance of the steel balls after quenching.

[0005] To this end, the technical solution adopted in this application is as follows: a steel ball quenching heat treatment equipment for steel ball production, comprising a heat treatment box, one side of the heat treatment box is provided with a loading preheating mechanism, the upper inner side of the heat treatment box is provided with an upper heating mechanism, the middle part of the heat treatment box is provided with a heating isolation mechanism, a swinging separate bearing mechanism is provided between the upper heating mechanism and the heating isolation mechanism, and also includes a driving mechanism for driving the loading preheating mechanism, the driving mechanism is connected to the swinging separate bearing mechanism through a linkage mechanism, and a discharge door is provided on the side of the heat treatment box away from the loading preheating mechanism.

[0006] By adopting the above technical scheme: supporting legs are provided at the bottom of the heat treatment box, and the steel balls are heated in the heat treatment box. The loading and preheating mechanism on one side of the heat treatment box can realize temporary storage and loading of the steel balls and preheat the steel balls. The upper heating mechanism is used to increase and maintain the temperature inside the heat treatment box. The heating isolation mechanism can isolate the steel balls in rows. At the same time, the pre-swinging separation bearing mechanism cooperates to isolate multiple steel balls without contact between the steel balls. At the same time, a single steel ball can be rolled and heated, so that the surface of each steel ball is heated more evenly, and the hardness and wear resistance of the steel ball after quenching are improved. The driving mechanism and the linkage mechanism can be linked to drive the swinging separation bearing mechanism and the loading and preheating mechanism to act synchronously. The loading is performed first and then the swing is performed to make the steel ball roll, so that its surface is heated more evenly.

[0007] Optionally, the feeding preheating mechanism comprises a preheating box arranged on one side of the heat treatment box, the preheating box is provided with a feeding inclined plate, and the lower part of the feeding inclined plate is connected to the driving mechanism.

[0008] By adopting the above technical solution: the preheating box is used for temporarily storing and preheating steel balls. Driven by the driving mechanism, the loading ramp can drive the steel balls thereon to move upward. Because the loading ramp is tilted downward at one end close to the heat treatment box, when reaching the swinging separation bearing mechanism, the steel balls can roll to the swinging separation bearing mechanism by relying on their own gravity to realize loading.

[0009] Optionally, the upper heating mechanism includes a fixing plate connected to the top of the heat treatment box, and a plurality of electric heating tubes are provided on the fixing plate.

[0010] By adopting the above technical solution: fixing multiple electric heating tubes on a fixed plate, the temperature inside the heat treatment box can be increased. The temperature of the electric heating tubes can be controlled by a control system, etc., thereby facilitating the control of the heating temperature inside the heat treatment box.

[0011] Optionally, the heating isolation mechanism includes a mounting plate arranged inside the heat treatment box, and a plurality of rows of heating isolation blocks are provided on the mounting plate, a first gap is provided between two adjacent rows of heating isolation blocks, and a second gap is provided between two adjacent heating isolation blocks in each row.

[0012] By adopting the above technical solution: the rows of heating isolation blocks can further heat the inside of the heat treatment box. When heat treating the steel balls, they intermittently contact the steel balls, so that the surface of the steel balls is heated more evenly, wherein the first gap is larger than the diameter of the steel balls, and the steel balls roll between two adjacent rows of heating isolation blocks.

[0013] Optionally, the swinging separation type bearing mechanism includes a supporting square rod slidably arranged on both sides of the mounting plate, a hinged frame is provided at the upper end of the supporting square rod, a bearing plate is rotatably connected to the hinged frame via a hinge axis, a hollow portion is provided in the middle of the bearing plate, a plurality of bearing bars are evenly distributed in parallel in the hollow portion, the diameter of the bearing bar is smaller than the width of the second gap, and the lower part of the supporting square rod is in contact with and connected to the linkage mechanism.

[0014] By adopting the above technical scheme: the supporting square rod can be reciprocated up and down relative to the mounting plate under the drive of the linkage mechanism, so that the bearing plate can be reciprocated up and down relative to the mounting plate. Specifically, when loading, under the drive of the driving mechanism, the linkage mechanism first drives the bearing plate to move upward, so that it is separated from the heating isolation block on the mounting plate, and then no longer moves. Then the driving mechanism continues to push the loading inclined plate upward to lift the steel ball and roll it onto the bearing plate. Specifically, the steel balls are between two adjacent bearing bars and arranged in rows. When the linkage mechanism returns, the bearing plate also returns downward, and the bearing bars gradually enter the second gap. The heating isolation block separates the rows of steel balls separately, and each steel ball is equivalent to being in the isolation space formed between the two bearing bars and the two heating isolation blocks. Multiple steel balls do not contact each other, so that the surface is heated more evenly. At the same time, the subsequent linkage mechanism can also drive the two sides of the bearing plate to intermittently flip up and down, so that the steel balls can roll in the above-mentioned isolation space, further improving its heating uniformity.

[0015] Optionally, the driving mechanism includes a telescopic power member arranged on the heat treatment box and located at the lower part of the preheating box, the upper end of the output shaft of the telescopic power member is connected to the loading inclined plate, and the linkage mechanism includes a moving component arranged on the lower side of the mounting plate for driving the supporting plate to move up and down, and a swinging component for driving the supporting plate to swing.

[0016] By adopting the above technical solution: the telescopic power part can adopt an electric cylinder, an oil cylinder or a pneumatic cylinder, etc., which is convenient for controlling its telescopic amount, and can drive the loading inclined plate to move upward to load the steel balls. The moving component can drive the supporting plate to move up and down under the drive mechanism, and the swinging component can drive the two sides of the supporting plate to swing up and down, so that the steel balls can roll.

[0017] Optionally, a limiting telescopic square rod is slidably provided through the middle part of the lower side wall of the heat treatment box body, and a bearing seat is provided on the limiting telescopic square rod. The moving assembly includes a moving body rotatably connected to the bearing seat, a push plate is provided on the output shaft, and the lower end of the limiting telescopic square rod is on the push plate. A first supporting slider and a second supporting slider are provided on both sides of the moving body for top-connecting the supporting square rod, and the tops of the first supporting slider and the second supporting slider are provided with inclined portions with opposite inclination directions.

[0018] By adopting the above technical solution: the limiting telescopic square rod has elasticity and telescopic range, a square hole is provided on the lower side wall of the heat treatment box, and the limiting telescopic square rod is inserted into the square hole to prevent shaft rotation, and the bearing seat is used to rotate and install the moving body. When the output shaft moves upward, the limiting telescopic square rod can be pushed upward by the push plate, thereby driving the moving body to move up and down. At this time, the first supporting slider and the second supporting slider can push the supporting square rod to move upward, thereby driving the bearing plate to separate from the heating isolation block, which is convenient for loading steel balls in rows.

[0019] Optionally, a limiting block for limiting the bearing seat is provided in the middle of the mounting plate, and the slope of the inclined portion on the first supporting sliding block is greater than the slope of the inclined portion of the second supporting sliding block.

[0020] By adopting the above technical solution: when the bearing seat contacts the limit block, the bearing no longer moves upward, that is, the movable body no longer moves upward, and since the limit telescopic square rod has a telescopic amount, the output shaft can continue to move upward, and the movable body can be rotated by the swing assembly, and with the help of the first supporting slider and the inclined portion of the second supporting slider, the supporting plate on one side of the loading and preheating mechanism can be moved upward, and the supporting plate at the other end of the discharge door can be moved downward, so that the supporting plate has an inclined angle of movement, and at this time the driving mechanism drives the loading inclined plate to move to the high end of the supporting plate, and the steel ball can roll onto the supporting bar of the supporting plate to complete the loading, wherein the slope of the inclined portion on the first supporting slider is greater than the slope of the inclined portion of the second supporting slider, which can complete the swing of the supporting plate under a smaller rotation amount of the movable body.

[0021] Optionally, the swing assembly includes a swing groove arranged on the side of the first supporting slider and a shift rod arranged on the output shaft, the end of the shift rod is located in the swing groove, and the swing groove includes a connected entry guide portion, an inclined groove portion and a vertical groove portion.

[0022] By adopting the above technical solution: the entry guide portion makes it easier for the lever to enter the swing groove, the inclined groove portion serves as a driving groove, and the lever can only move up and down. When it slides in the inclined groove portion, it forces the moving body to rotate, thereby realizing the swing of the above-mentioned supporting plate, and the vertical groove portion can serve as a buffer portion. When the lever moves to the vertical groove portion, the moving body can no longer rotate, and a certain movement buffer can be formed to avoid jamming.

[0023] Optionally, the vertical length of the first supporting slide block is greater than the vertical length of the second supporting slide block, and an embedding groove for accommodating the lower portion of the first supporting slide block is provided inside the heat treatment box.

[0024] By adopting the above technical solution, it is convenient to set the length of the swing groove, the inclination angle of the inclined groove part, etc.

[0025] The working principle and beneficial effects of this application are: 1. In the present application, a support leg is provided at the bottom of the heat treatment box, and the steel ball is heated in the heat treatment box. The feeding preheating mechanism on one side of the heat treatment box can realize temporary storage and feeding of the steel ball, and can preheat the steel ball. The upper heating mechanism is used to increase and maintain the temperature inside the heat treatment box. The heating isolation mechanism can isolate the steel balls in rows, and the pre-swinging separation bearing mechanism cooperates to isolate multiple steel balls without contact between the steel balls. At the same time, a single steel ball can be rolled and heated, so that the surface of each steel ball is heated more evenly, and the hardness and wear resistance of the steel ball after quenching are improved. The driving mechanism and the linkage mechanism can be linked to drive the swinging separation bearing mechanism and the feeding preheating mechanism to act synchronously, first load the material and then swing to make the steel ball roll, so that the surface is heated more evenly; 2. In the present application, the supporting square rod can be reciprocated up and down relative to the mounting plate under the drive of the linkage mechanism, so that the bearing plate can be reciprocated up and down relative to the mounting plate. Specifically, when loading, under the drive of the driving mechanism, the bearing plate is first driven upward by the linkage mechanism to separate the heating isolation block on the mounting plate, and then no longer moves. Then the driving mechanism continues to push the loading inclined plate upward to lift the steel ball and roll it onto the bearing plate. Specifically, the steel balls are between two adjacent bearing bars and arranged in rows. When the linkage mechanism returns, the bearing plate also returns downward, and the bearing bar gradually enters the second gap. The heating isolation block separates the rows of steel balls separately, and each steel ball is equivalent to being in the isolation space formed between the two bearing bars and the two heating isolation blocks. Multiple steel balls do not contact each other, so that the surface is heated more evenly. At the same time, the subsequent linkage mechanism can also drive the two sides of the bearing plate to intermittently flip up and down, so that the steel balls can roll in the above-mentioned isolation space, further improving the uniformity of heating. 3. In the present application, when the bearing seat contacts the limit block, the bearing no longer moves upward, that is, the movable body no longer moves upward. Since the limit telescopic square rod has a telescopic amount, the output shaft can continue to move upward. The movable body can be rotated by the swing assembly. With the help of the first supporting slider and the inclined portion of the second supporting slider, the bearing plate on one side of the loading preheating mechanism can be moved upward, and the bearing plate at the other end of the discharge door can be moved downward, so that the bearing plate has an inclined angle of movement. At this time, the driving mechanism drives the loading inclined plate to move to the high end of the bearing plate, and the steel ball can roll onto the bearing bar of the bearing plate to complete the loading. The slope of the inclined portion on the first supporting slider is greater than the slope of the inclined portion of the second supporting slider, which can enable the bearing plate to swing under a smaller rotation amount of the moving body, thereby facilitating loading.

DETAILED DESCRIPTION

[0029] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figure 1-Figure 7As shown, this embodiment provides a steel ball quenching heat treatment equipment for steel ball production, including a heat treatment box 100, which is mainly used to heat treat the steel balls loaded into the inside thereof, and a loading preheating mechanism 200 is provided on one side of the heat treatment box 100 for preheating and loading the steel balls, and an upper heating mechanism 300 is provided on the upper side of the heat treatment box 100, and a heating isolation mechanism 400 is provided in the middle of the heat treatment box 100, and the upper heating mechanism 300 and the heating isolation mechanism 400 are connected to each other. A swinging separate carrying mechanism 500 is provided in between, and also includes a driving mechanism 600 for driving the loading preheating mechanism 200 to move. The driving mechanism 600 is connected to the swinging separate carrying mechanism 500 through a linkage mechanism 700. A discharge door 800 is provided on the side of the heat treatment box 100 away from the loading preheating mechanism 200. A supporting leg 130 is provided at the bottom of the heat treatment box 100. The driving mechanism 600 is installed on the crossbeam between the two supporting legs 130 on one side of the loading preheating mechanism 200.

[0031] The basic principle of this embodiment is as follows: a support leg 130 is provided at the bottom of the heat treatment box 100, and the steel balls are heated in the heat treatment box 100. The loading and preheating mechanism on one side of the heat treatment box 100 can realize the temporary storage and loading of the steel balls, and can preheat the steel balls. The upper heating mechanism 300 is used to increase and maintain the temperature inside the heat treatment box 100. The heating isolation mechanism 400 can isolate the steel balls in rows. At the same time, the pre-swinging separation bearing mechanism 500 cooperates to isolate multiple steel balls without contact between the steel balls. At the same time, a single steel ball can be rolled and heated, so that the surface of each steel ball is heated more evenly, and the hardness and wear resistance of the steel ball after quenching are improved. The driving mechanism 600 and the linkage mechanism 700 can be linked to drive the swinging separation bearing mechanism 500 and the loading and preheating mechanism 200 to act synchronously, first loading and then swinging to make the steel balls roll, so that the surface is heated more evenly.

[0032] like Figure 1 As shown, the loading and preheating mechanism 200 in this embodiment includes a preheating box 210 arranged on one side of the heat treatment box 100, and a loading inclined plate 220 is provided in the preheating box 210. The lower part of the loading inclined plate 220 is connected to the driving mechanism 600. The preheating box 210 is used for temporarily storing and preheating steel balls. Driven by the driving mechanism 600, the loading inclined plate 220 can drive the steel balls thereon to move upward. Because the end of the loading inclined plate 220 close to the heat treatment box 100 is inclined downward, when reaching the swinging separation supporting mechanism 500, the steel balls can roll to the swinging separation supporting mechanism 500 by relying on their own gravity to realize loading.

[0033] like Figure 1As shown, the upper heating mechanism 300 in this embodiment includes a fixed plate 310 connected to the top of the heat treatment box 100, and a plurality of electric heating tubes 320 are provided on the fixed plate 310. By fixing the plurality of electric heating tubes 320 on the fixed plate 310, the temperature inside the heat treatment box 100 can be increased. The temperature of the electric heating tubes 320 can be controlled by a control system, etc., thereby facilitating the control of the heating temperature inside the heat treatment box 100.

[0034] like Figure 2 and Figure 3 As shown, the heating isolation mechanism 400 in this embodiment includes a mounting plate 410 arranged inside the heat treatment box 100, and a plurality of rows of heating isolation blocks 420 are provided on the mounting plate 410, a first gap 430 is provided between two adjacent rows of heating isolation blocks 420, and a second gap 440 is provided between two adjacent heating isolation blocks 420 in each row, and the rows of heating isolation blocks 420 can further heat the inside of the heat treatment box 100, and when heat treating the steel balls, they intermittently contact the steel balls, so that the surface of the steel balls is heated more evenly, wherein the first gap 430 is larger than the diameter of the steel balls, and the steel balls roll between the two adjacent rows of heating isolation blocks 420.

[0035] The swing-separate bearing mechanism 500 in this embodiment includes a supporting square rod 510 slidably inserted on both sides of the mounting plate 410, and an articulated frame 520 is provided at the upper end of the supporting square rod 510. A bearing plate 540 is rotatably connected to the articulated frame 520 through a hinge shaft 530. A hollow portion is provided in the middle of the bearing plate 540, and a plurality of bearing bars 550 are evenly distributed in parallel at the hollow portion. The diameter of the bearing bar 550 is smaller than the width of the second gap 440, and the lower part of the supporting square rod 510 is in contact with and connected to the linkage mechanism 700.

[0036] The more specific action principle is as follows: the supporting square rod 510 can be reciprocated up and down relative to the mounting plate 410 under the drive of the linkage mechanism 700, so that the bearing plate 540 can be reciprocated up and down relative to the mounting plate 410. Specifically, when loading, the driving mechanism 600 drives the bearing plate 540 to move upward through the linkage mechanism 700, so that it is separated from the heating isolation block 420 on the mounting plate 410, and then it does not move. Then the driving mechanism 600 continues to push the loading inclined plate 220 upward to lift the steel ball and roll it onto the bearing plate 540. Specifically, the steel ball is located between two adjacent bearing bars. 550, and are arranged in rows. When the linkage mechanism 700 returns, the supporting plate 540 also returns downward, and the supporting bar 550 gradually enters the second gap 440. The heating isolation block 420 separates the rows of steel balls individually. Each steel ball is equivalent to being in the isolation space formed between the two supporting bars 550 and the two heating isolation blocks 420. The multiple steel balls do not contact each other, so that their surfaces are heated more evenly. At the same time, the subsequent linkage mechanism 700 can also drive the two sides of the supporting plate 540 to intermittently flip up and down, so that the steel balls can roll in the above-mentioned isolation space, further improving the heating uniformity.

[0037] like Figure 1 , Figure 4-Figure 6 As shown, the driving mechanism 600 in this embodiment includes a telescopic power member arranged on the heat treatment box 100 and at the lower part of the preheating box 210, the upper end of the output shaft of the telescopic power member is connected to the loading inclined plate 220, and the linkage mechanism 700 includes a moving component arranged on the lower side of the mounting plate 410 for driving the supporting plate 540 to move up and down, and a swinging component for driving the supporting plate 540 to swing. The telescopic power member can adopt an electric cylinder, an oil cylinder or an air cylinder, etc., which is convenient for controlling its telescopic amount, and can drive the loading inclined plate 220 to move upward to load the steel balls. The moving component can drive the supporting plate 540 to move up and down under the drive of the driving mechanism 600, and the swinging component can drive the two sides of the supporting plate 540 to swing up and down, so that the steel balls can roll.

[0038] In this embodiment, a limiting telescopic square rod 110 is slidably penetrated in the middle of the lower side wall of the heat treatment box 100, and a bearing seat 710 is arranged on the limiting telescopic square rod 110. The moving assembly includes a moving body 720 rotatably connected to the bearing seat 710, and a push plate 760 is arranged on the output shaft. The lower end of the limiting telescopic square rod 110 is located on the push plate 760, and a first supporting slider 730 and a second supporting slider 740 for top-connecting the supporting square rod 510 are arranged on both sides of the moving body 720. The tops of the first supporting slider 730 and the second supporting slider 740 are provided with inclined portions 750 with opposite inclined directions. The telescopic square rod 110 has elasticity and telescopic capacity. A square hole is provided on the lower side wall of the heat treatment box 100. The telescopic square rod 110 is passed through the square hole to prevent shaft rotation. The bearing seat 710 is used to rotate and install the movable body 720. When the output shaft moves upward, the telescopic square rod 110 can be pushed upward by the push plate 760, thereby driving the movable body 720 to move up and down. At this time, the first supporting slider 730 and the second supporting slider 740 can push the supporting square rod 510 to move upward, thereby driving the bearing plate 540 to separate from the heating isolation block 420, which is convenient for loading steel balls in rows.

[0039] A limiting block 411 for limiting the bearing seat 710 is provided in the middle of the mounting plate 410. The slope of the inclined portion 750 on the first supporting slider 730 is greater than the slope of the inclined portion 750 of the second supporting slider 740. When the bearing seat 710 contacts the limiting block 411, the bearing no longer moves upward, that is, the moving body 720 no longer moves upward. Since the limiting telescopic square rod 110 has a telescopic amount, the output shaft can continue to move upward. The moving body 720 can be rotated by the swing assembly. Figure 5 In the rotation direction shown, the first supporting slider 730 and the second supporting slider 740 rotate counterclockwise, and with the help of the inclined portion 750 of the first supporting slider 730 and the second supporting slider 740, the supporting plate 540 on one side of the loading preheating mechanism 200 can be moved upward, and the supporting plate 540 at the other end of the discharge door 800 can be moved downward, so that the supporting plate 540 has a moving tilt angle. At this time, the driving mechanism 600 drives the loading inclined plate 220 to move to the high end of the supporting plate 540, and the steel ball can roll onto the supporting bar 550 of the supporting plate 540 to complete the loading, wherein the slope of the inclined portion 750 on the first supporting slider 730 is greater than the slope of the inclined portion 750 of the second supporting slider 740, so that the swing of the supporting plate 540 can be completed under a smaller rotation amount of the moving body 720.

[0040] The swing assembly includes a swing groove 770 arranged on the side of the first supporting slider 730 and a lever 780 arranged on the output shaft, the end of the lever 780 is in the swing groove 770, and the swing groove 770 includes a connected entry guide portion 771, an inclined groove portion 772 and a vertical groove portion 773. The entry guide portion 771 facilitates the lever 780 to enter the swing groove 770, and the inclined groove portion 772 is used as a driving groove, so that the lever 780 can only move up and down. When it slides in the inclined groove portion 772, it forces the moving body 720 to rotate, thereby realizing the swing of the above-mentioned bearing plate 540, and the vertical groove portion 773 can be used as a buffer portion. When the lever 780 moves to the vertical groove portion 773, the moving body 720 can no longer rotate, and a certain amount of movement buffer can be formed to avoid jamming.

[0041] like Figure 5-Figure 7 As shown, the vertical length of the first support slider 730 is greater than the vertical length of the second support slider 740, and the heat treatment box 100 is provided with an embedding groove 120 for accommodating the lower part of the first support slider 730, so that it is convenient to set the length of the swing groove 770, the inclination angle of the inclined groove part 772, etc. When the moving body 720 moves down to the lowest end, the lever 780 is still inside the inclined groove part 772, and the telescopic power part moves up and down in a small range, which can drive the moving body 720 to swing, so that the bearing plate 540 can swing up and down, and the steel ball can roll, further improving its heat treatment effect.

[0042] After the heat treatment of the steel balls is completed, the support plate 540 is lifted again, and one end of the support plate 540 close to the loading preheating mechanism 200 is higher than the other end, and the material discharge door 800 is opened, so that the steel balls can roll out of the heat treatment box 100.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
