Description

Technical Field

[0001] The invention relates to the technical field of shaft body processing, in particular to an intermediate full-shaft normalizing device and a process thereof for producing a motor shaft. Background Art

[0002] The intermediate full shaft normalizing device is a device used to normalize the intermediate full shaft. Normalizing is a heat treatment process that heats the metal material to an appropriate temperature above the critical temperature, keeps it warm for a certain period of time, and then cools it in the air. For the intermediate full shaft, the purpose of normalizing is usually to improve its organizational structure and refine the grains, thereby improving the mechanical properties of the shaft, such as strength and toughness.

[0003] The device mainly realizes the normalizing process through the heating system, temperature control system and cooling system. The heating system is responsible for heating the entire shaft to the specified normalizing temperature range, the temperature control system ensures the accuracy and stability of the heating temperature, and the cooling system ensures that the shaft is cooled at an appropriate speed in the air. During use, a conveying device is required for transportation. During the use of the conveying device, the conveying structure will be affected by high temperature. The high temperature environment will have an adverse effect on the various components of the motor of the conveying structure. The winding inside the motor of the conveying structure is usually made of metal wires such as copper or aluminum. These metals will expand thermally at high temperatures. If the motor of the conveying structure is in a high temperature area for a long time, the repeated thermal expansion and contraction of the winding may cause damage to the insulation layer. Once the insulation layer is damaged, it is easy to cause a short circuit failure, thereby shortening the service life of the motor of the conveying structure. Summary of the invention

[0015] S2. When the entire intermediate shaft reaches the normalizing temperature, a certain heating time is set according to the size and material of the entire intermediate shaft, and the entire intermediate shaft is continuously heated to the specified temperature;

[0016] S3. After the heating time is reached, the adjustable guide plate moves the entire intermediate shaft out of the heating furnace and enters the insulation part of the normalizing operation chamber for cooling.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The piston rod of the first electric push rod drives the end of the adjustable guide plate away from the rotating shaft to move upward, and the end of the adjustable guide plate away from the rotating shaft is supported and tilted by the first electric push rod, thereby driving the motor shaft to move from the higher end to the lower end on the adjustable guide plate. After normalizing is completed, the end of the next adjustable guide plate away from the rotating shaft moves downward, and the end of the adjustable guide plate at the initial position away from the rotating shaft moves upward, and the motor shaft continues to move to the next adjustable guide plate. The lifting and lowering of the outer end of the adjustable guide plate drives the motor shaft to move. The part of the driving motor shaft to move is relatively far away from the heating part, and it will not be affected by the heating part. The high temperature environment will have an adverse effect on the various components of the motor of the conveying structure. Since it is away from high temperature, the failure probability of the motor of the conveying structure can be reduced, and the maintenance cost of the motor of the conveying structure is correspondingly reduced. In a high temperature environment, the electrical components and mechanical components of the motor of the conveying structure are more prone to failure, and need to be frequently inspected, repaired and replaced. In the continuous heat treatment and processing production line of the shaft body, the rotating guide rail can quickly transfer the shaft body according to the preset program.

[0019] 2. When the temperature of the normalizing part in the normalizing operation chamber is high, the hot air channel valve can be opened, and the higher temperature airflow can be pumped into the normalizing operation chamber corresponding to the insulation part in the normalizing operation chamber through the air pump. The insulation board can also be opened to ensure that the airflow is from the normalizing side to the insulation side in the normalizing operation chamber. During the normalizing process, the normalizing chamber needs to heat the workpiece to a higher temperature, which usually consumes a lot of energy to generate and maintain this high temperature environment. When the high temperature air in the normalizing chamber is moved to the insulation chamber, the air with heat can be reused. The main purpose of the insulation chamber is to keep the workpiece within a certain temperature range. Using the waste heat of the normalizing chamber can reduce the energy required to heat the insulation chamber alone. BRIEF DESCRIPTION OF THE DRAWINGS

The shaped fixed seat 3 is rotatably connected with a rotating shaft 4, and an adjustable guide plate 5 is fixedly sleeved on each rotating shaft 4, that is, the adjustable guide plates 5 are in two groups, and the two groups of adjustable guide plates 5 are symmetrically designed front and back, and the adjustable guide plates 5 are transversely arranged in the normalizing operation chamber 1, and the adjustable guide plates 5 are arranged at the center of the normalizing operation chamber 1, giving the adjustable guide plates 5 sufficient upward swinging space, and the bottom of the adjustable guide plates 5 away from the rotating shaft 4 is fixedly installed with an assembly base plate 6, and the bottom center of the assembly base plate 6 is fixedly installed with an upper fixed seat 7, and the bottom of the inner wall of the normalizing operation chamber 1 is fixedly installed with an upper fixed seat 7. A lower fixed card seat 8 is arranged at the position corresponding to the upper fixed card seat 7, and a first electric push rod 9 is arranged between the upper fixed card seat 7 and the lower fixed card seat 8 for connection. The bottom of the first electric push rod 9 and the top of the piston rod are fixedly installed with a rotating card head 10, and the two rotating card heads 10 are respectively rotatably connected with the upper fixed card seat 7 and the lower fixed card seat 8. The rotating card head 10 is pushed upward by the piston rod of the first electric push rod 9, and the upward movement of the rotating card head 10 drives the adjustable guide plate 5 to rotate around the annular fixed seat 3, and at the same time, the rotating card head 10 is rotated on the upper The rotation in the fixed holder 7 and the rotation of the rotating holder 10 in the lower fixed holder 8 are used to adapt to the extension and retraction of the piston rod of the first electric push rod 9. An arc guide rail 11 is fixedly installed at the bottom of the assembly base plate 6. U-shaped buckles 12 are provided on both sides of the inner wall of the normalizing operation chamber 1. The arc guide rail 11 is located in the U-shaped buckle 12, and the arc guide rail 11 is slidably connected to the U-shaped buckle 12. The U-shaped buckle 12 moves on the arc guide rail 11 to limit the movement trajectory of the assembly base plate 6, thereby ensuring the stability and smoothness of the movement of the U-shaped buckle 12 on the arc guide rail 11.

[0037] The arc guide rail 11 is arranged with the central axis corresponding to the rotating shaft 4 as the center, and limits the rotation of the adjustable guide plate 5, so as to ensure the rotation effect of the adjustable guide plate 5.

[0038] A second electric push rod 13 is fixedly installed on both sides of the top of the adjustable guide plate 5, and a swinging pressure rod 14 is rotatably connected to the top of the piston rod of the second electric push rod 13. A rectangular sleeve 15 is fixedly installed on the side of the swinging pressure rod 14 close to the inside. A telescopic pressure head 16 is movably inserted in the rectangular sleeve 15, and one end of the telescopic pressure head 16 away from the rectangular sleeve 15 is rotatably connected to a rotating pressure wheel 17. A buffer spring 18 is fixedly installed on one end of the telescopic pressure head 16 located in the rectangular sleeve 15, and the buffer spring 18 is fixedly installed in the rectangular sleeve 15. The buffer spring 18 supports the telescopic pressure head 16 and the rotating pressure wheel 17 to ensure the pressure effect of the rotating pressure wheel 17 and the buffer spring 18 on the outer wall of the motor shaft. The motor shaft is fixed by the rolling connection between the rotating pressure wheel 17 and the motor shaft, and the fixing effect of the motor shaft is ensured by the support of the bottom of the adjustable guide plate 5 and multiple rotating pressure wheels 17.

[0039] An inclined support bar 19 is fixedly installed on the top of the piston rod of the second electric push rod 13. The top of the inclined support bar 19 is inclined inward. The inclined support bar 19 restricts the swinging pressure rod 14 and limits the rotation angle of the swinging pressure rod 14 to ensure that the swinging pressure rod 14 does not rotate outward.

[0040] A transverse assembly bottom strip 20 is fixedly installed on one side of the bottom of the adjustable guide plate 5 near the unloading end, a third electric push rod 21 is fixedly installed on the bottom of the transverse assembly bottom strip 20, a U-shaped baffle 22 is fixedly installed on the top of the piston rod of the third electric push rod 21, and a lifting slot 501 corresponding to the shape of the U-shaped baffle 22 is opened on the adjustable guide plate 5. The U-shaped baffle 22 is pushed up and down by the piston rod of the third electric push rod 21. The U-shaped baffle 22 applies pressure to the end of the motor shaft to fix the motor shaft. At the same time, one side of the U-shaped baffle 22 is a hollow device to reduce the weight of the U-shaped baffle 22.

[0041] A driving motor 23 is fixedly installed at the bottom of the adjustable guide plate 5, and a driving gear 24 is fixedly installed on the output shaft of the driving motor 23. The driving gear 24 is fixed by a gear assembly frame 25 set at the bottom of the adjustable guide plate 5. A rotating card slot 502 is opened on the adjustable guide plate 5, and a driving roller 26 is rotatably connected in the rotating card slot 502. A driven gear 27 meshing with the driving gear 24 is fixedly installed at the center position of the driving roller 26. The driving motor 23 drives the driving gear 24 to rotate in the gear assembly frame 25. The driven gear 27 meshing with the driven gear 27 is driven to rotate, thereby driving the transmission roller 26 to rotate, and the transmission roller 26 drives the motor shaft to rotate, so as to realize the normalization of the motor shaft in all directions. The normalization of the motor shaft in the rotating state can make the shaft heat more evenly in the circumferential direction and axial direction. When the motor shaft is normalized at rest, the heating source may cause the local temperature of the shaft surface to be too high or too low. The uniform heating is conducive to more effective grain refinement of the motor shaft during the normalizing process. An important purpose of normalizing is to refine the grain by controlling the heating and cooling process, thereby improving the mechanical properties of the material. When the motor shaft rotates and is heated evenly, the organizational transformation of the entire shaft body is more synchronized.

[0042] A gantry 28 is fixedly installed on the top of the normalizing operation chamber 1, and a fourth push rod 29 is fixedly installed on the top of the gantry 28. A heat insulation board 30 is fixedly installed on the end of the piston rod of the fourth push rod 29. The heat insulation board 30 is movably inserted in the normalizing operation chamber 1, and the heat insulation board 30 is driven to rise and fall by the piston rod of the fourth push rod 29, so that the motor shaft can move on the two adjustable guide plates 5, one adjustable guide plate 5 corresponds to heating, and the other adjustable guide plate 5 corresponds to insulation. The normalizing operation chamber is separated by heat-blocking plates to divide different temperature zones. During the normalizing process, the temperature of the area close to the heating source is higher, while the temperature of the area far away from the heating source is relatively low. The heat insulation board 30 can be adjusted to rise and fall, and the position of the heat insulation board 30 can be flexibly adjusted according to the size of the workpiece in the normalizing operation chamber. For normalizing treatment of large workpieces, the heat insulation board 30 is raised to connect the operation chamber, which can provide sufficient space for the workpiece to pass smoothly and avoid the heat insulation board 30 causing obstruction to the entry or movement of the workpiece. The adjustable heat insulation board 30 is convenient for the inspection and maintenance of the internal equipment of the normalizing operation chamber. When it is necessary to inspect or repair the heating elements, conveying devices or temperature sensors in the operation chamber, the heat insulation board 30 is raised to provide a wider operating space, which is convenient for maintenance personnel to enter and operate.

[0043] A hot air conduit 31 is fixedly installed on one side of the normalizing operation chamber 1, and a hot air channel valve 32 is arranged on the hot air conduit 31. The ports of the hot air conduit 31 are located on both sides of the heat insulation board 30. The hot air channel valve 32 controls the flow of air in the hot air conduit 31. The opening and closing of the hot air channel valve 32 controls the air flow from one side of the heat insulation board 30 to the other side, so as to realize energy recycling. The use of high-temperature air in the normalizing chamber in the insulation chamber helps to better control the insulation temperature. The temperature of the high-temperature air in the normalizing chamber is relatively stable and has been verified by the normalizing process. Introducing it into the insulation chamber can provide a more ideal initial temperature environment for the insulation chamber. In this way, during the insulation process, the temperature fluctuation will be smaller, which is conducive to ensuring the heat treatment quality of the product. The effective use of heat can shorten the time for the insulation chamber to reach the predetermined insulation temperature. Under normal circumstances, the insulation chamber needs a certain amount of time to heat up. The use of high-temperature air in the normalizing chamber can speed up this process. From the perspective of energy consumption of the entire heat treatment system, this heat transfer makes the energy more reasonably allocated between different processing links.

[0044] An intermediate sealing plate 33 is provided between the proximal ends of the two adjustable guide plates 5 for connection, so as to ensure smooth movement of the motor shaft on the two adjustable guide plates 5 .

[0045] A normalizing process for the intermediate shaft of a motor shaft production, S1, placing the intermediate shaft on an adjustable guide plate 5, slowly sending the intermediate shaft to a heating part, the temperature control system starts to work, and according to the preset heating speed and normalizing temperature, the heating power of the normalizing operation chamber 1 is adjusted to gradually heat up the intermediate shaft;

[0046] S2. When the entire intermediate shaft reaches the normalizing temperature, a certain heating time is set according to the size and material of the entire intermediate shaft, and the entire intermediate shaft is continuously heated to the specified temperature;

[0047] S3. After the heating time is reached, the adjustable guide plate 5 moves the entire intermediate shaft out of the heating furnace and enters the insulation part of the normalizing operation chamber 1 for cooling. During the insulation process, the insulation system ensures that the entire intermediate shaft is evenly cooled at a suitable speed until the temperature of the entire intermediate shaft drops to a suitable range, completing the normalizing treatment.

[0048] Working principle:

[0049] The first step: open the thermal insulation door 2, place the motor shaft on the adjustable guide plate 5, the swing pressure rod 14 adapts to the size of the motor shaft by swinging, the rotating pressure wheel 17 and the buffer spring 18 form a structure in contact with the motor shaft, and when the pressure is too large, the telescopic pressure head 16 can be retracted into the rectangular sleeve 15, and the U-shaped baffle 22 is driven to move upward by the piston rod of the third electric push rod 21 to ensure that the U-shaped baffle 22 protrudes to limit the movement of the motor shaft. After the U-shaped baffle 22 protrudes, the adjustable guide plate 5 is driven by the piston rod of the first electric push rod 9 to move upward at one end away from the rotating shaft 4, and the end of the adjustable guide plate 5 away from the rotating shaft 4 is supported and tilted up by the first electric push rod 9, thereby driving the motor shaft to move from a higher end to a lower end on the adjustable guide plate 5. After the motor shaft moves to the specified position on the upper surface of the adjustable guide plate 5, it is stopped by the U-shaped baffle 22, and the adjustable guide plate 5 rotates in the opposite direction to reset, and the motor shaft is heated by the heating equipment in the normalizing operation chamber 1. During the heating of the motor shaft, the driving motor 23 is driven to drive the driving gear 24 to rotate on the gear assembly frame 25. When the driving gear 24 rotates, the driven gear 27 is also driven to rotate, thereby driving the transmission roller 26 to rotate in the rotating slot 502, thereby driving the motor shaft in contact with the transmission roller 26 to rotate. During the rotation of the motor shaft, it contacts the rotating pressure wheel 17, and the rotation stability of the motor shaft is ensured through the contact between the rotating pressure wheel 17 and the motor shaft. After normalizing is completed, the U-shaped baffle 22 on the first adjustable guide plate 5 retracts, and the U-shaped baffle 22 on the next adjustable guide plate 5 extends out. The end of the first adjustable guide plate 5 away from the rotating shaft 4 moves upward, and the motor shaft continues to move to the next adjustable guide plate 5. The end of the next adjustable guide plate 5 away from the rotating shaft 4 moves downward and is limited by the U-shaped baffle 22 on the next adjustable guide plate 5. The motor shaft is located on the next adjustable guide plate 5 for insulation operation.

[0050] Step 2: During the closing process of the insulation door 2, it is necessary to ensure the stability of the temperature in the normalizing operation chamber 1 corresponding to the normalizing part of the adjustable guide plate 5. After the temperature in the normalizing operation chamber 1 is relatively high, the hot air channel valve 32 can be opened, and the higher temperature airflow can be pumped into the normalizing operation chamber 1 corresponding to the insulation part in the normalizing operation chamber 1 through the air pump to ensure the insulation process. The insulation plate 30 can also be opened to ensure that the airflow is from the normalizing side to the insulation side in the normalizing operation chamber 1.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
