Description

Technical Field

[0001] The present invention belongs to the technical field of metal heat treatment, and in particular relates to heat treatment equipment and a process for producing and processing metal materials. Background Art

[0002] Metal heat treatment is a process that alters the internal structure of metals by heating and cooling them, thereby improving their mechanical, physical, and chemical properties. Common heat treatment methods include quenching, normalizing, and tempering, which can be performed individually or in combination. Quenching is the process of heating a metal to an appropriate temperature and then rapidly cooling it to increase its hardness and strength. Tempering is the process of heating the metal to a temperature below its critical point after quenching, holding it at that temperature, and then cooling it to reduce the internal stresses generated by quenching, lowering its hardness, and improving its toughness. Heat treatment is widely used in the processing and production of various metal parts.

[0003] In the prior art, when heat treating slender shaft parts, thermal induction heating combined with synchronous water spraying is usually used for rapid quenching. While ensuring uniform and stable quenching quality, it can also ensure processing efficiency to a certain extent. However, the existing heat treatment equipment for slender shaft parts can usually only quench one or two slender shaft parts at the same time, which wastes manpower and time and leads to low production efficiency. After the shaft parts are quenched, workers need to manually unload the materials and then transfer, place or clamp them to the tempering equipment for tempering process. This process also wastes time and cannot achieve continuous and efficient heat treatment production. In addition, during the transfer and re-clamping process, if tempering is not performed in time, the probability of the shaft parts being deformed by stress will increase, affecting production quality.

[0004] A Chinese patent with authorization announcement number CN220746024U discloses a slender shaft quenching device, comprising a base, a fixed cylinder fixedly mounted on the upper surface of the base, a lower top rotatably mounted on the upper surface of the base, the lower top being arranged inside the fixed cylinder, a rotating cylinder rotatably mounted on the top wall of the fixed cylinder, and an upper top slidably mounted on the inner wall of the rotating cylinder. An operator manually pulls up a pull-out column, causing the pull-out column to drive the upper top to move upward along a limiting slide. The operator positions the slender shaft between the upper top and the lower top through two top holes, and uses a tension spring to hold the slender shaft in place with the upper top. The slender shaft is fixed by this device to prevent the fixture from blocking the surface of the slender shaft. The outer surface of the slender shaft can be subjected to temperature quenching treatment with only one clamping operation, making it convenient for workers to operate and clamp to improve production efficiency.

[0005] However, the above patent still has the following shortcomings:

[0006] 1. According to the description of the above patent, although the above patent simplifies the process of clamping slender shafts, facilitates workers' operation and improves production efficiency, it still requires clamping, heat treatment and blanking operations to be performed in sequence. It is impossible to perform clamping work while performing heat treatment. Continuous production is impossible, which wastes a lot of time and reduces production efficiency.

[0007] 2. When clamping a slender shaft, the above patent still requires workers to pass the shaft through the induction coil before clamping it. When clamping a long shaft with a high center of gravity, it is difficult to control and inconvenient to operate, which is not conducive to workers to clamp quickly and affects production efficiency.

[0008] 3. The above patent can only quench the shaft, and the shaft parts need to be tempered as soon as possible after quenching to remove the internal stress of the shaft and avoid bending and deformation of the shaft. However, after quenching, the above patent is still like the traditional heat treatment process, which requires unloading and then transferring before the shaft can be tempered. Delaying time can easily cause deformation of the shaft. Summary of the Invention

DETAILED DESCRIPTION

[0036] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0037] Example 1:

[0038] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 and Figure 8 As shown, a heat treatment equipment for the production and processing of metal materials includes a base 10, an outer cover 11 with an opening is fixedly connected to the base 10, a turntable 12 is rotatably connected in the outer cover 11, a plurality of shaft grooves 13 are evenly distributed on the outside of the turntable 12, the opening of the outer cover 11 only allows one shaft groove 13 to be exposed to the outside, and a shaft 14 can be placed in each shaft groove 13, a main shaft 31 rotatably connected to the base 10 is fixedly connected at the center of the turntable 12, the main shaft 31 passes through the bottom end of the base 10 and is fixedly connected to a first synchronous wheel 32, a second motor 35 is fixedly connected to the base 10 at one side of the outer cover 11, a power output end of the second motor 35 passes through the base 10 and is transmission-connected to the second synchronous wheel 33, and a synchronous belt 34 is transmission-connected between the first synchronous wheel 32 and the second synchronous wheel 33.

[0039] By setting up a rotatable turntable 12, each shaft 14 is automatically driven to transfer, so that the shaft 14 is subjected to quenching, tempering and cooling processes in sequence, thereby achieving efficient and continuous processing without the need for repeated loading and unloading and transferring of the shaft 14 between each process, thereby improving the continuity between processes and effectively avoiding the internal stress of the shaft 14 causing the shaft 14 to bend and deform due to the failure to temper the shaft 14 in time after quenching, thereby improving production efficiency and processing quality.

[0040] like Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, the upper end of the turntable 12 is fixedly connected to a wheel seat 36 at the corresponding position of each shaft groove 13, and an end cap 37 is rotatably connected to each wheel seat 36. Each end cap 37 covers the top of the corresponding shaft 14. The bottom end of each shaft groove 13 is fixedly connected to a threaded seat 43, and a threaded rod 44 is threadedly connected to each threaded seat 43. A thimble 46 is rotatably connected to the top of each threaded rod 44, and each thimble 46 can be pushed against the bottom end of the corresponding shaft 14. A handwheel 45 is fixedly connected to the outer side of the top of each threaded rod 44.

[0041] By providing the end cap 37 and the ejector pin 46 , the shaft 14 can be stably fixed. When in use, the ejector pin 46 can be raised or lowered by rotating the hand wheel 45 , thereby conveniently completing loading and unloading.

[0042] like Figure 5 and Figure 6 As shown, each end cap 37 extends out of the top of the wheel seat 36 and is fixedly connected to a driven wheel 38. The top of the turntable 12 is located at a position corresponding to each driven wheel 38 and is rotatably connected to a driving wheel 40. A transmission belt 39 is connected between each driven wheel 38 and the corresponding driving wheel 40. A third motor 42 is fixedly connected to the center of the top of the outer cover 11. The power output end of the third motor 42 passes through the outer cover 11 and is transmission-connected to a driving gear 41. The driving gear 41 is meshed and transmission-connected with each driving wheel 40.

[0043] During the heat treatment process, the third motor 42 drives each end cap 37 to rotate, thereby driving each shaft 14 to rotate at a uniform speed, so that the shaft 14 can be evenly heated during the heat treatment process, thereby ensuring that all parts of the shaft 14 are evenly heat treated and the processing quality is guaranteed.

[0044] like Figure 4 、 Figure 6 and Figure 7As shown, a first slider 15 is slidably connected in each shaft groove 13, and a first coil 17 surrounding the outside of the shaft 14 is fixedly connected to each first slider 15. A screw cover 28 is fixedly connected to the outside of the outer cover 11 at one side of the opening of the outer cover 11, and a second slider 16 is slidably connected in the screw cover 28. The second slider 16 is fixedly connected to the second coil 18 surrounding the outside of the shaft 14. The first coil 17 and the second coil 18 can be assembled into a complete spiral coil, and a sleeve 19 covering and fixing the first coil 17 and the second coil 18 is fixedly connected to the second slider 16 and each first slider 15. The sleeve 19 is made of high-temperature resistant material.

[0045] By providing a first coil 17 and a second coil 18 that can be assembled with each other, which are directly opened when located at the opening of the outer cover 11, compared with the traditional loading process, there is no need to pass the slender shaft 14 through the induction coil, which facilitates operation and improves loading efficiency. After the subsequent rotation of the turntable 12, the first coil 17 and the second coil 18 are docked to form a complete induction coil surrounding the outside of the shaft 14, thereby realizing the quenching process of the shaft 14 by induction heating.

[0046] like Figure 1 、 Figure 3 、 Figure 4 and Figure 6 As shown, a screw 27 is rotatably connected in the screw cover 28, and a first motor 29 is fixedly connected to the top of the screw cover 28. The power output end of the first motor 29 is transmission-connected to the top of the screw 27. A screw slider 26 is threadedly connected to the screw 27, and the screw slider 26 is fixedly connected to the second slider 16. A connecting pin 20 is provided on the side of each first slider 15 close to the second slider 16, and a slide groove 21 is provided on the side of the second slider 16 close to the first slider 15 at the corresponding position of each connecting pin 20. The connecting pin 20 and the slide groove 21 can be plugged in. A card slot 22 is provided on each connecting pin 20, and a retaining spring 23 is fixedly connected in each slide groove 21.

[0047] By setting the connecting pin 20 and the slide groove 21, the first slider 15 and the second slider 16 can be assembled with each other, and then cooperate with the threaded connection between the screw slider 26 and the screw 27 to drive the second slider 16 to drive the first slider 15 to rise or fall, so that the entire shaft 14 can be fully quenched. By setting the card slot 22 and the retaining spring 23, it can be ensured that the first coil 17 and the second coil 18 can be accurately docked, and in the process of the second slider 16 driving the first slider 15 to rise, the stability of the docking and assembly of the first coil 17 and the second coil 18 is guaranteed, thereby ensuring the stable effect of inductive heating of the shaft 14.

[0048] like Figure 1 、 Figure 3 、 Figure 4 and Figure 6As shown, a nozzle seat 24 is fixedly connected to the second slider 16 below the screw slider 26, and a nozzle 25 is fixedly connected to the bottom of the nozzle seat 24. The nozzle 25 points to the shaft 14, and a through drainage hole 30 is opened at the bottom of the screw cover 28. The water pipe connected to the nozzle 25 and the cable connected to the second coil 18 pass through the drainage hole 30.

[0049] By setting up the nozzle 25, after the shaft 14 is induction heated, water can be sprayed synchronously to quench the shaft 14. In conjunction with the rotation of the shaft 14, it can ensure that the shaft 14 is in uniform contact with the water flow, thereby ensuring the quenching effect, and the excess water is discharged outside the equipment through the drainage hole 30.

[0050] like Figure 1 、 Figure 2 、 Figure 3 and Figure 8 As shown, a tempering chamber shell 47 communicating with the interior of the outer cover 11 is fixedly connected to the outer side of the outer cover 11 on one side of the screw cover 28, and a plurality of heating rods 48 surrounding the outer side of the turntable 12 are evenly distributed and fixedly connected in the tempering chamber shell 47. A heater 49 communicating with each heating rod 48 is provided at one end of the tempering chamber shell 47, and a plurality of through exhaust holes 50 are evenly distributed in the circumferential direction on the top of the tempering chamber shell 47. A plurality of through heat dissipation holes 51 are evenly distributed on the surface of the outer cover 11 on the side away from the screw cover 28.

[0051] By providing the tempering chamber shell 47 and the heating rod 48, the residual moisture on the surface of the shaft 14 after quenching can be dried, and the shaft 14 can be tempered at the same time. There is no interval between quenching and tempering, so that the shaft 14 can be tempered in time to remove stress and improve the processing quality. By providing the heat dissipation holes 51, the shaft 14 can be cooled and dissipated after tempering, so as to avoid overheating of the shaft 14 and scalding the operator during subsequent unloading.

[0052] In this embodiment, initially, the operator connects the device to the power supply and control system, and then the heater 49 is started to generate heat for the heating rod 48 to preheat the interior of the tempering chamber shell 47. The temperature inside the tempering chamber shell 47 can be adjusted to a suitable range by the heater 49.

[0053] At this time, a shaft groove 13 is exposed at the opening of the outer cover 11. The operator holds the shaft 14 to be processed, inserts the upper end of the shaft 14 into the end cap 37, aligns the lower end of the shaft 14 with the ejector pin 46, and turns the handwheel 45 to lift the ejector pin 46 until the ejector pin 46 is stably pressed against the bottom end of the shaft 14, thereby supporting the shaft 14. Since the first coil 17 is completely open at this time, there is no need to pass the slender shaft 14 through the induction coil, which makes the operation convenient and quick, thereby improving production efficiency.

[0054] Subsequently, under the control of the control system, the second motor 35 starts and drives the turntable 12 to move the shaft 14 through the transmission connection of the first synchronous wheel 32 and the second synchronous wheel 33. The shaft 14 is transferred to the screw cover 28 to wait for quenching, and the subsequent empty shaft groove 13 is exposed at the opening of the outer cover 11, and the operator performs the loading operation again.

[0055] During the process of the turntable 12 rotating to transfer the shaft 14 to the corresponding position of the screw cover 28, the first slider 15 and the second slider 16 are at the same height, and the connecting pin 20 slides stably into the corresponding slide groove 21, so that the first slider 15 and the second slider 16 are spliced ​​with each other, and the retaining spring 23 is engaged into the corresponding retaining groove 22, so that the first coil 17 and the second coil 18 are stably and accurately docked, forming a complete induction coil surrounding the outside of the shaft 14. Subsequently, the control system supplies power to the second coil 18 to form an induced current, thereby induction heating the shaft 14.

[0056] At the same time, the control system starts the first motor 29, and drives the second slider 16 to lift the first slider 15 upward through the threaded connection between the screw slider 26 and the screw 27, thereby performing comprehensive induction heating on the slender shaft 14 as a whole. At the same time, water is sprayed out from the nozzle 25. After the coil formed by the first coil 17 and the second coil 18 heats the shaft 14, the shaft 14 is promptly brought into contact with the water flow for quenching, and excess water is discharged from the drain hole 30. After the second slider 16 and the first slider 15 move to the top, heating and water spraying are no longer performed, and the screw 27 rotates in the opposite direction to cause the second slider 16 to lower and reset with the first slider 15, completing the quenching process.

[0057] Subsequently, the turntable 12 rotates the first slider 15 and the second slider 16 again to disengage, so that the quenched shaft 14 enters the range of the tempering chamber shell 47. At the same time, the new shaft 14 enters the corresponding position of the screw cover 28, and the other first slider 15 is spliced ​​with the second slider 16 to perform the quenching process. The shaft 14 entering the range of the tempering chamber shell 47 is subjected to the high temperature in the tempering chamber shell 47. The residual moisture on the surface of the shaft 14 evaporates, and the water vapor is discharged from the exhaust hole 50. The shaft 14 is in a uniform and stable temperature environment in the tempering chamber shell 47, and the tempering process is performed to remove stress to avoid bending and deformation of the shaft 14. After quenching, it directly enters the tempering process, which is timely and fast, eliminating the time for repeated clamping and transfer, improving production efficiency, and reducing the probability of bending caused by the shaft 14 not being tempered in time during the transfer process.

[0058] The range of the tempering chamber shell 47 covers multiple shaft components 14, so during the subsequent multiple quenching processes, multiple shaft components 14 can be fully tempered, while ensuring that the shaft components 14 are tempered sufficiently in the tempering chamber shell 47 to ensure the heat treatment effect.

[0059] When the shaft 14 moves out of the range of the tempering chamber shell 47 with the rotation of the turntable 12, the shaft 14 is at the position corresponding to the heat dissipation hole 51, and is in the process of quenching and tempering other shafts 14. The outside air of the equipment contacts the shaft 14 through the heat dissipation hole 51, so that the shaft 14 is cooled and dissipated. Finally, the shaft 14 continues to move again with the turntable 12 and returns to the opening of the outer cover 11. The operator turns the handwheel 45 to lower the ejector pin 46, removes the cooled shaft 14, and then loads a new shaft 14, realizing continuous and complete assembly line heat treatment processing and greatly improving production efficiency.

[0060] During the above process, the third motor 42 drives the driving gear 41 to rotate, and then through the transmission of the driven wheel 38 and the driving wheel 40, the driving end cap 37 drives the shaft 14 to rotate, ensuring that the shaft 14 can be evenly heated and dissipated during the quenching, tempering and cooling processes, thereby ensuring the uniformity of the shaft 14 after processing and ensuring the processing quality. During each loading and unloading process and the rotation of the turntable 12, the third motor 42 is turned off to prevent the shaft 14 from rotating, which facilitates loading and unloading and process switching.

[0061] Example 2:

[0062] A heat treatment process for the production and processing of metal materials, the process flow is as follows:

[0063] S1: Loading process, the operator directly installs the shaft 14 to be processed between the end cap 37 and the ejector pin 46, and then the turntable 12 rotates to drive the shaft 14 into the subsequent heat treatment process, and the processes are directly continuous;

[0064] S2: Quenching process: The shaft 14 is driven by the turntable 12 to the position corresponding to the second slider 16. The first coil 17 and the second coil 18 are combined to generate an induced current to heat the shaft 14. The nozzle 25 sprays water to quench the shaft 14 and lifts the first slider 15 and the second slider 16. The entire shaft 14 is quenched and reset after completion.

[0065] S3: Drying process: After quenching, the shaft 14 is again transferred to the tempering chamber shell 47 under the drive of the turntable 12. The heating rod 48 generates heat to evaporate the residual moisture on the surface of the shaft 14, and the moisture is discharged from the exhaust hole 50;

[0066] S4: Tempering process, the shaft 14 is always in a suitable and stable temperature environment within the entire coverage of the tempering chamber shell 47, so that the stress in the shaft 14 after quenching is eliminated, achieving the effect of the tempering process;

[0067] S5: Cooling process. After the tempering process, the shaft 14 is again transferred by the turntable 12 to the position corresponding to the heat dissipation hole 51 for static heat dissipation;

[0068] S6: Unloading process, the shaft 14 after heat dissipation is finally transferred back to the opening of the outer cover 11, the operator turns the hand wheel 45 to loosen the clamping of the shaft 14, and finally removes the heat-treated shaft 14, and then the loading process can be continued.
