Description

Technical Field

[0001] The invention relates to the field of high frequency quenching, and more specifically to a high frequency quenching device for sprocket processing. Background Art

[0002] High-frequency quenching is to use the skin effect and proximity effect generated when high-frequency current (usually refers to the current with a frequency in the range of thousands to millions of hertz) passes through the workpiece to quickly heat the surface of the workpiece to the quenching temperature, and then quickly cool it to achieve the purpose of improving the surface hardness and wear resistance of the workpiece. The equipment used is usually an induction heating equipment, that is, the workpiece is inductively heated. The workpiece is placed in an inductor, which is generally a hollow copper tube that inputs medium-frequency or high-frequency alternating current;

[0003] When high-frequency quenching the sprocket, first place the sprocket on the workbench and fix it with a clamp. Then, place the sprocket in the high-frequency induction coil. Through the induction of the high-frequency electromagnetic field, the surface of the sprocket is quickly heated to the quenching temperature. Finally, use cold water or other quenching media for quenching to allow the surface of the sprocket to cool rapidly to achieve the quenching effect.

[0004] In the prior art, due to small-scale production or small workpiece size, operators usually manually place the metal workpiece in the appropriate position of the high-frequency induction heating equipment. However, the temperature around the metal copper tube is low when it is used for the first time. As the metal workpiece is continuously processed, a large amount of heat will be generated around the metal copper tube. After repeated operations, the operator will relax due to increased fatigue, and there is a possibility of being burned by the high temperature around the metal copper tube. Summary of the invention

Since the storage seat drives the turntable to rotate ninety degrees on one side during the reciprocating up and down movement, only one batch of materials can be discharged at a time, so that different batches of materials maintain continuity during high-frequency quenching, thereby once again ensuring the high-frequency quenching efficiency of the materials.

[0021] (3) The present invention supports the material by means of the limit strip, and separates from the material after the material approaches the high-frequency quenching machine body. Since the limbs of the worker can still be away from the metal copper ring in the high-frequency quenching machine body during the material removal process, and the storage seat can complete the material transportation and removal during the up and down movement, the high-frequency quenching efficiency of the material is further improved.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 8 A high-frequency quenching device for sprocket processing includes a high-frequency quenching machine body 1 and a control box 101 fixedly installed on the back of the high-frequency quenching machine body 1. The control box 101 is in an inverted "L" shape. A servo motor 2 is fixedly installed on the upper side of the control box 101. A rotating rod 3 is fixedly connected to the output end of the servo motor 2. A screw rod 31 is fixedly connected to the bottom end of the rotating rod 3. A screw nut 4 is threadedly connected to the outer side of the screw rod 31. A feeding component 5 is provided inside and outside the control box 101.

[0034] The feeding component 5 includes a fixed sleeve 51 which is sleeved on the outside of the screw nut 4. A storage seat 52 is sleeved on the outside of the fixed sleeve 51. A slider 53 is fixedly connected to the back of the storage seat 52. A slide groove 54 is provided on the front of the vertical part of the control box 101. The slider 53 is slidably connected in the slide groove 54. After the upper side of the storage seat 52 moves upward, it contacts the lower side of the horizontal part of the control box 101. After the lower side of the storage seat 52 moves downward, it contacts the upper side of the high-frequency quenching machine body 1.

[0035] A material transfer assembly 55 is disposed inside the control box 101 .

[0036] The inside and outside of the control box 101 and the inside of the storage seat 52 are provided with a discharge assembly 56 .

[0037] By adopting the above technical solution, first, after the servo motor 2 is started, it will drive the rotating rod 3 to rotate, and after the rotating rod 3 rotates, it will drive the screw 31 passing through the turntable 554 to rotate. As the screw 31 rotates, the screw nut 4 on its outside will follow the trajectory of the external thread on the outside of the screw 31 and start to move up and down. During the movement of the screw nut 4, the fixed sleeve 51 on the outside of the screw nut 4 will move with the screw nut 4, and the storage seat 52 sleeved on the outside of the fixed sleeve 51 will move synchronously with the fixed sleeve 51. When the upper side of the storage seat 52 contacts the lower side of the horizontal part of the control box 101, the material transfer component 55 will cooperate with the discharge component 56 to transport the material to the inside of the storage seat 52. After the storage seat 52 carries the material and moves downward, it enters the high The high-frequency quenching machine body 1 is inside, and then the high-frequency induction heating equipment inside the high-frequency quenching machine body 1 is started through the control box 101 to drive the material to rotate and heat it at the same time. Then the high-frequency quenching machine body 1 will spray out the quenching medium for cooling, and the quenched material will be lifted and re-enter the storage seat 52 for collection. At the same time, the storage seat 52 will gradually move upward by driving the screw nut 4 through the screw rod 31. Since the material is transported away from the metal copper tube used for heating during high-frequency quenching, the large amount of heat around the metal copper tube can be avoided to cause burns to the operator after the operator is fatigued due to repeated operations. At the same time, the continuous transportation of the material will also improve the high-frequency quenching efficiency of the material.

[0038] like Figures 4 to 7 As shown, the upper part of the fixed sleeve 51 is composed of two identical vertical bars arranged in parallel, and the material transfer component 55 includes a first moving groove 551 opened on the outer side of the fixed sleeve 51, and the number of the first moving grooves 551 is two.

[0039] The first pressure springs 552 are fixedly connected to the adjacent sides of the two first moving grooves 551, and the ends of the two first pressure springs 552 that are away from each other are fixedly connected to the extrusion columns 553. The two extrusion columns 553 are respectively slidably connected in the two first moving grooves 551. The horizontal part of the high-frequency quenching machine body 1 is rotatably connected to a turntable 554. The turntable 554 is provided with guide grooves 555, and the number of the guide grooves 555 is two. After the fixed sleeve 51 moves upward, it is inserted into the turntable 554. After the fixed sleeve 51 is inserted into the turntable 554, the two extrusion columns 553 are respectively slidably connected in the two guide grooves 555. The two guide grooves 555 are staggered with each other. The sides of the two extrusion columns 553 that are away from each other are provided with inclined surfaces. After the two extrusion columns 553 enter the two guide grooves 555 respectively, the turntable 554 starts to rotate.

[0040] The discharge assembly 56 includes a first through hole 561 opened on the upper side of the turntable 554, and the number of the first through holes 561 is multiple. The first through hole 561 passes through the turntable 554. A notch 562 is opened on the front of the horizontal part of the control box 101. The turntable 554 is above the notch 562. After the turntable 554 rotates, the multiple first through holes 561 correspond to the notch 562. The notch 562 is above the storage seat 52. The storage seat 52 is internally slidably connected to a limit strip 563, and the number of the limit strips 563 is two.

[0041] By adopting the above technical solution, first, when the fixing sleeve 51 enters the rotating disk 554, the first pressure spring 552 in the first moving groove 551 continuously pushes the squeezing column 553, so that the squeezing column 553 is always exposed to the outside, and the inclined surface faces downward. As the two squeezing columns 553 continue to move upward, because the fixing sleeve 51 itself cannot rotate, but the rotating disk 554 can rotate, the squeezing column 553 applies an upward force in the guide groove 555, and the rotating disk 554 will start to rotate. When the storage seat 52 contacts downward, the rotating disk 554 rotates ninety degrees, and at this time, the first through hole 561 above the rotating disk 554 will drive the material to rotate. As the first through hole 561 carrying the material rotates to just above the notch 562, the material will pass through the first through hole 561. The hole 561 enters the notch 562 and finally enters the storage seat 52, and the two limit bars 563 inside the storage seat 52 will limit the material so that the material stays inside the storage seat 52. After the storage seat 52 collects the material, the storage seat 52 starts to move downward. At this time, the inclined surfaces of the two extrusion columns 553 will squeeze the inner wall of the guide groove 555 and retract into the first moving groove 551, so that the turntable 554 cannot continue to rotate. Repeat the above steps, and the material inside the turntable 554 will be transported intermittently. Since the storage seat 52 drives the turntable 554 to rotate ninety degrees on one side during the reciprocating up and down movement, only one batch of materials can be discharged at a time, so that different batches of materials maintain continuity during high-frequency quenching, which once again ensures the high-frequency quenching efficiency of the material.

[0042] like Figure 6 As shown, a limiting assembly 57 is provided inside the high-frequency quenching machine body 1 and inside the receiving seat 52. The limiting assembly 57 includes a second movable groove 571 opened inside the receiving seat 52, and the number of the second movable grooves 571 is two.

[0043] The two second movable grooves 571 are located on the left and right sides of the storage seat 52. The two second movable grooves 571 are slidably connected to the inside of the two second movable grooves 571 with connecting plates 572. The connecting plates 572 are "L" shaped. The upper side of the storage seat 52 is provided with a hollow cavity 575, and the hollow cavity 575 runs through the storage seat 52. The two second movable grooves 571 are provided with an embedding groove 573 on one side of the opposite surface inside. The two embedding grooves 573 are fixedly connected to the tension spring 574 on one side of the opposite surface inside. The two tension springs 574 are fixedly connected to the two tension springs 574. The ends of the two connecting plates 574 that are away from each other are respectively fixedly connected to the opposite surfaces of the two connecting plates 572. The opposite surfaces of the two connecting plates 572 are provided with inclined surfaces. A pushing block 576 is fixedly connected to the interior of the high-frequency quenching machine body 1. After the storage seat 52 moves downward, the pushing block 576 is inserted into the hollow cavity 575. After the pushing block 576 enters the hollow cavity 575, it is squeezed and contacted with the inclined surfaces of the two connecting plates 572. After the two connecting plates 572 are pushed by the pushing block 576, the two limit strips 563 are driven away.

[0044] By adopting the above technical solution, first, in the process of the storage seat 52 driving the material to move downward, the tension spring 574 embedded in the groove 573 always pulls the connecting plate 572, and the connecting plate 572 is fixed to the limit bar 563, so that the two limit bars 563 can support the material. As the storage seat 52 continues to move downward, when the pushing block 576 inside the high-frequency quenching machine body 1 enters the hollow cavity 575 of the storage seat 52, the pushing block 576 will simultaneously push the inclined surfaces of the two connecting plates 572, so that the two connecting plates 572 gradually move away from each other, and while the connecting plate 572 moves, the limit bar 563 will move with the connecting plate 572, and the material will directly enter the high-frequency quenching machine body 1 after losing the restriction from the two limit bars 563. After the high-frequency quenching of the material by the high-frequency quenching machine body 1 is completed , the structure of the high-frequency quenching machine body 1 will drive the material to move upward and gradually pass through the storage seat 52. At this time, the screw rod 31 rotating in the opposite direction will drive the storage seat 52 to move upward through the screw rod nut 4 and the fixed sleeve 51. As the two connecting plates 572 lose the extrusion from the pushing block 576, the tension spring 574 embedded in the groove 573 will drive the connecting plate 572, so that the two connecting plates 572 quickly approach each other. At this time, the two limit bars 563 will also be reset and support the material again. During the rising process of the storage seat 52, the material can be taken out from the inside of the storage seat 52. Since the limbs of the staff can still be away from the metal copper ring in the high-frequency quenching machine body 1 during the process of taking out the material, and the storage seat 52 can complete the material transportation and removal during the process of moving up and down, the high-frequency quenching efficiency of the material is further improved.

[0045] like Figures 2 to 5 and Figure 8As shown, a guide assembly 58 is provided inside the horizontal portion of the control box 101 , and the guide assembly 58 includes a fixed plate 581 fixedly connected to the upper side of the rotating plate 554 , and the fixed plate 581 is sleeved on the outer side of the rotating rod 3 .

[0046] A second through hole 582 is provided on the upper side of the fixed plate 581, and the number of the second through holes 582 is multiple, the second through holes 582 penetrate the fixed plate 581, the interiors of the multiple second through holes 582 are slidably connected with guide columns 583, the upper sides of the multiple guide columns 583 are fixedly connected with positioning seats 584, the upper sides of the multiple positioning seats 584 are hinged with rollers 585, the lower sides of the multiple positioning seats 584 are fixedly connected with second pressure springs 586, and the number of the second pressure springs 586 is two, the bottom ends of the multiple second pressure springs 586 are fixedly connected to the upper side of the fixed plate 581, and the inner upper side of the horizontal part of the control box 101 is fixedly connected with a protrusion 587, and the protrusion 587 is located above and to the left of the notch 562.

[0047] By adopting the above technical solution, first, when the turntable 554 transports the material through the first through hole 561, the fixed plate 581 on the upper side of the turntable 554 will rotate with it. At the same time, movable guide columns 583 are arranged in the multiple second through holes 582 on the surface of the fixed plate 581, and the positioning seat 584 above the guide column 583 is supported above the fixed plate by the second pressure spring 586. After the turntable 554 rotates, the fixed plate 581 and the structure inside the second through hole 582 will also move together. When the first through hole 561 is about to dock with the notch 562, the roller 585 above the positioning seat 584 will first contact the protrusion 587. As the turntable 554 continues to rotate, the positioning seat 584 will drive the guide column 583 to move downward, and make After the guide column 583 is inserted into the material, and the first through hole 561 is connected with the notch 562, the material will gradually slide downward from the outside of the guide column 583 and finally be discharged through the notch 562. After the roller 585 is separated from the protrusion 587, the second pressure spring 586 under the positioning seat 584 will quickly reset the positioning seat 584 and the guide column 583. The above steps are repeated. During subsequent material transportation, the guide column 583 is downward and inserted into the material. Since the friction between the guide column 583 and the guide column 583 will increase during the material separation process, the material descent speed is reduced, which effectively reduces the impact force during the material descent process to avoid damage to the material surface. At the same time, the guide column 583 can also ensure the stable fall of the material to prevent the material from escaping from the notch 562.

[0048] like Figures 2 to 5 As shown, a cleaning component 6 is provided inside and on the upper side of the horizontal portion of the control box 101 , and the cleaning component 6 includes a scraper 61 fixedly connected to the lower side of the turntable 554 .

[0049] A plurality of cleaning brushes 62 are fixedly connected to the lower inner side of the horizontal portion of the control box 101. After the scraper 61 rotates, it is squeezed and contacted with the upper sides of the plurality of cleaning brushes 62. The plurality of cleaning brushes 62 are respectively arranged below the plurality of first through holes 561. No cleaning brush 62 is arranged below the first through hole 561 above the notch 562. A fan 63 is fixedly installed on the upper inner side of the horizontal portion of the control box 101, and the fan 63 extends to the inner side of the horizontal portion of the control box 101.

[0050] By adopting the above technical solution, first, during the rotation of the turntable 554, the fan 63 above the control box 101 will continue to blow toward the inside of the control box 101, and at the same time, the scraper 61 below the turntable 554 contacts the lower side of the inside of the control box 101 and the cleaning brush 62 above it, and the material in the first through hole 561 will always be above the cleaning brush 62. After the turntable 554 drives the material to rotate, the cleaning brush 62 will clean the lower side of the material, and the airflow generated by the fan 63 will blow toward the surface of the material except the lower side. Since the airflow generated by the fan 63 always blows toward the material, the dust remaining on the surface of the material can be processed, and the lower side of the material will be cleaned by the cleaning brush 62. After the turntable 554 rotates, the scraper 61 will scrape off the dust on the airflow entering and exiting the control box 101 and on the surface of the cleaning brush 62 to avoid the dust from affecting the subsequent high-frequency quenching of the material.

[0051] Working principle: First, the servo motor 2 drives the screw 31 passing through the turntable 554 to rotate through the rotating rod 3. As the screw 31 rotates, the screw nut 4 on the outside thereof will begin to drive the fixing sleeve 51 on the outside thereof to move together, and the storage seat 52 sleeved on the outside of the fixing sleeve 51 will also move synchronously with the fixing sleeve 51. When the upper side of the storage seat 52 contacts the lower side of the horizontal part of the control box 101, the fixing sleeve 51 first enters the inside of the turntable 554. Because the first pressure spring 552 in the first moving groove 551 continuously pushes the extrusion column 553, the extrusion column 553 is always exposed. The outer side of the rotating disk 554 is inclined downward, and as the two extrusion columns 553 continue to move upward, because the fixing sleeve 51 itself cannot rotate, but the rotating disk 554 can rotate, the extrusion columns 553 exert an upward force inside the guide groove 555, and the rotating disk 554 will start to rotate. When the storage seat 52 contacts downward, the rotating disk 554 rotates ninety degrees, and at this time, the first through hole 561 above the rotating disk 554 will drive the material to rotate. As the first through hole 561 carrying the material rotates to the top of the notch 562, the fixed disk 581 on the upper side of the rotating disk 554 will rotate with it, and the fixed disk 581 on the upper side of the rotating disk 554 will rotate with it, and the fixed disk 581 on the upper side of the rotating disk 554 will rotate with it. A plurality of second through holes 582 on the surface of the disk 581 are each provided with a movable guide column 583, and the positioning seat 584 above the guide column 583 is supported above the fixed plate by the second pressure spring 586. After the turntable 554 rotates, the fixed disk 581 and the structure inside the second through hole 582 will also move together. When the first through hole 561 is about to dock with the notch 562, the roller 585 above the positioning seat 584 will first contact the protrusion 587. As the turntable 554 continues to rotate, the positioning seat 584 will drive the guide column 583 to move downward, and make The guide post 583 is inserted into the material, and after the first through hole 561 is connected with the notch 562, the material will gradually slide downward from the outside of the guide post 583 and finally be discharged through the notch 562. After the roller 585 is separated from the protrusion 587, the second pressure spring 586 under the positioning seat 584 will quickly reset the positioning seat 584 and the guide post 583, and the material will enter the notch 562 through the first through hole 561 and finally enter the storage seat 52. The two limiting bars 563 inside the storage seat 52 will limit the material so that the material stays inside the storage seat 52.

[0052] After the storage seat 52 collects the material, the storage seat 52 starts to move downward. At this time, the inclined surfaces of the two squeezing columns 553 squeeze the inner wall of the guide groove 555 and retract into the first moving groove 551, so that the turntable 554 cannot continue to rotate. Because the tension spring 574 embedded in the groove 573 always pulls the connecting plate 572, and the connecting plate 572 is fixed to the limit bar 563, so that the two limit bars 563 can support the material. As the storage seat 52 continues to move downward, when the pushing block 576 inside the high-frequency quenching machine body 1 enters the hollow cavity 575 of the storage seat 52, the material is pushed into the storage seat 52. After the material is moved inside, the push block 576 will simultaneously push the inclined surfaces of the two connecting plates 572, so that the two connecting plates 572 gradually move away from each other. When the connecting plates 572 move, the limit bars 563 will move with the connecting plates 572. After losing the restriction from the two limit bars 563, the material will directly enter the high-frequency quenching machine body 1. Then, the high-frequency induction heating device inside the high-frequency quenching machine body 1 is started through the control box 101 to drive the material to rotate and heat it at the same time. Then, the high-frequency quenching machine body 1 will spray out the quenching medium for cooling, and the quenched material will be lifted up and heated at the high-frequency quenching machine body 1. After the quenching machine body 1 completes the high-frequency quenching of the material, the structure of the high-frequency quenching machine body 1 will drive the material to move upward and gradually pass through the storage seat 52. At this time, the screw rod 31 rotating in the opposite direction will drive the storage seat 52 to move upward through the screw rod nut 4 and the fixing sleeve 51. As the two connecting plates 572 lose the extrusion from the pushing block 576, the tension spring 574 embedded in the groove 573 will drive the connecting plate 572, so that the two connecting plates 572 quickly approach each other. At this time, the two limit bars 563 will also be reset, and the material will be supported again, and re-enter the storage seat 52 for collection. At the same time, the storage seat 52 will gradually move upwards by driving the screw nut 4 through the screw 31. At the same time, when the turntable 554 is rotating, the fan 63 above the control box 101 will continue to blow into the control box 101. The scraper 61 below the turntable 554 contacts the lower side of the control box 101 and the cleaning brush 62 above it, and the material in the first through hole 561 will always be above the cleaning brush 62. After the turntable 554 drives the material to rotate, the cleaning brush 62 will clean the lower side of the material, and the airflow generated by the fan 63 will blow to the surface of the material except the lower side.
