Description

Technical Field

[0001] The invention belongs to the technical field of metal heat treatment, and specifically relates to heat treatment equipment and a process for metal material production and processing. Background Art

[0002] Metal heat treatment is a process that changes 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 alone or in combination. Quenching is the process of heating a metal to an appropriate temperature and then rapidly cooling it to increase hardness and strength. Tempering is the process of heating the metal to a temperature below the critical point after quenching, keeping it warm and then cooling it to reduce the internal stress generated by quenching, reduce hardness and improve 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 due to stress will increase, affecting the production quality.

[0004] The Chinese patent with the authorization announcement number CN220746024U discloses a slender shaft quenching device, including a base, a fixed cylinder is fixedly installed on the upper surface of the base, a lower top is rotatably installed on the upper surface of the base, the lower top is arranged inside the fixed cylinder, a rotating cylinder is rotatably installed on the top wall of the fixed cylinder, and an upper top is slidably installed on the inner wall of the rotating cylinder. The operator manually pulls the pulling column upward, so that the pulling column drives the upper top to move upward along the limiting slide groove, and the operator positions the slender shaft between the upper top and the lower top through two top holes, and the upper top is used to support the slender shaft through the tension spring. 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, which is convenient for workers to operate and clamp to improve production efficiency.

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

[0006] 1. According to the description of the above patent, although the above patent simplifies the process of clamping slender shaft parts, facilitates workers' operation and improves production efficiency, it still requires clamping, heat treatment and unloading operations in sequence. It is impossible to perform clamping work while performing heat treatment. If continuous production is not possible, a lot of time will be wasted, resulting in reduced production efficiency.

[0007] 2. When clamping a slender shaft, the above patent still requires workers to first pass the shaft through the induction coil and then clamp 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 perform quenching treatment on shaft parts, and shaft parts need to be tempered as soon as possible after quenching to remove the internal stress of the shaft parts and avoid bending and deformation of the shaft parts. However, after quenching, the above patent still needs to unload and transfer the shaft parts for tempering like the traditional heat treatment process, which delays time and easily causes deformation of the shaft parts.

[0037] Embodiment 1:

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 8 As shown, a heat treatment equipment for metal material production and processing 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 outer side 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 a second synchronous wheel 33, a synchronous belt 34 is transmission-connected between the first synchronous wheel 32 and the second synchronous wheel 33,

[0039] By providing a rotatable turntable 12, each shaft component 14 is automatically driven to transfer, so that the shaft component 14 is subjected to quenching, tempering and cooling processes in sequence, and efficient continuous processing is achieved without the need for repeated loading and unloading and transfer of the shaft component 14 between each process, thereby improving the continuity between processes and effectively avoiding the shaft component 14 from being bent and deformed due to internal stress in the shaft component 14 caused by failure to temper the shaft component 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 in 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 in each threaded seat 43. A top end of each threaded rod 44 is rotatably connected to a pin 46, and each pin 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 member 14 can be stably fixed. When in use, the ejector pin 46 can be raised or lowered by rotating the hand wheel 45, so that loading and unloading can be completed conveniently.

[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 corresponding position of each driven wheel 38 and is rotatably connected to a driving wheel 40. A transmission belt 39 is transmission-connected between each driven wheel 38 and the corresponding driving wheel 40. A third motor 42 is fixedly connected at the top center 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 member 14 to rotate at a uniform speed, so that the shaft member 14 can be evenly heated during the heat treatment process, thereby ensuring that each part of the shaft member 14 is 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. A second coil 18 surrounding the outside of the shaft 14 is fixedly connected to the second slider 16. 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, and 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, they are directly opened when located at the opening of the outer cover 11. Compared with the traditional feeding process, there is no need to pass the slender shaft 14 through the induction coil, which facilitates operation and improves feeding efficiency. After the subsequent rotation of the turntable 12, the first coil 17 and the second coil 18 are connected 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 lead screw 27 is rotatably connected inside the lead screw cover 28, a first motor 29 is fixedly connected to the top of the lead screw cover 28, a power output end of the first motor 29 is transmission-connected to the top of the lead screw 27, a lead screw slider 26 is threadedly connected to the lead screw 27, the lead 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, 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, each connecting pin 20 is provided with a card slot 22, 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 shaft member 14 can be fully quenched as a whole, and by setting the groove 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 member 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, 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, and a water pipe connected to the nozzle 25 and a cable connected to the second coil 18 pass through the drainage hole 30.

[0049] By setting the nozzle 25, after the shaft 14 is induction heated, water can be sprayed synchronously to quench the shaft 14. In combination with the rotation of the shaft 14, the shaft 14 can be evenly contacted with the water flow to ensure the quenching effect, and the excess water can be 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 at one side of the screw cover 28, 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, a plurality of through exhaust holes 50 are evenly distributed in a circumferential direction on the top of the tempering chamber shell 47, and a plurality of through heat dissipation holes 51 are evenly distributed on the surface of the outer cover 11 at 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. The quenching and tempering are continuous without interval, 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 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 a power source and a control system, and then the heater 49 is started to cause the heating rod 48 to generate heat 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 hand wheel 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 is started and connected through the transmission of the first synchronous wheel 32 and the second synchronous wheel 33, driving the turntable 12 to drive the shaft 14 to move, and the shaft 14 is transferred to the screw cover 28 to wait for quenching, and the subsequently empty shaft groove 13 is exposed at the opening of the outer cover 11, and the operator performs the loading operation again.

[0055] When the turntable 12 rotates 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 stably slides into the corresponding slide groove 21, so that the first slider 15 and the second slider 16 are assembled with each other, and the retaining spring 23 is engaged with the corresponding retaining groove 22, so that the first coil 17 and the second coil 18 are stably and accurately connected to form 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 to induction heat 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, so as to perform 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 bring the first slider 15 down and reset, completing the quenching process.

[0057] Subsequently, the turntable 12 rotates again to disengage the first slider 15 and the second slider 16, 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 assembled 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, and 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, saving the time of 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, the multiple shaft components 14 can be fully tempered, and at the same time, the tempering time of the shaft components 14 in the tempering chamber shell 47 is sufficient 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 hand wheel 45 to lower the ejector pin 46, removes the cooled shaft 14, and then loads a new shaft 14, thereby 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, thereby facilitating loading and unloading and switching of processes.

[0061] Embodiment 2:

[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 corresponding position of the second slider 16, the first coil 17 and the second coil 18 are combined to form an induction current to heat the shaft 14, the nozzle 25 sprays water to quench the shaft 14, and the first slider 15 and the second slider 16 are lifted, the shaft 14 is quenched as a whole, and reset after completion;

[0065] S3: Drying process: after quenching, the shaft 14 is again transferred to the tempering chamber shell 47 driven by the turntable 12, and the heating rod 48 generates heat to evaporate the residual water on the surface of the shaft 14, and the water vapor 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 coverage of the entire tempering chamber shell 47, so that the stress in the shaft 14 after quenching is eliminated, and the tempering process effect is achieved;

[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, and the operator turns the hand wheel 45 to loosen the clamping of the shaft 14, and finally removes the shaft 14 after heat treatment, and then the loading process can be continued.
