Specifically, a plurality of support plates arranged at intervals along the vertical direction are symmetrically arranged on both sides of the vertical plate. At the same time, the support grooves on the support plates can make the ball screw evenly heated during the tempering process, allowing heat to circulate, avoiding local overheating or overcooling of the ball screw, thereby ensuring the uniformity of the tempering treatment, improving the quality stability of the ball screw, and stably improving the metallographic structure of the ball screw. Moreover, the support grooves can adapt to ball screws of different specifications and sizes to replace the traditional fixture form.

[0018] The working principle of the trolley type tempering furnace: Cleaning and inspection: Before tempering, it is necessary to ensure that the surface of the ball screw is clean, free of oil, rust and other impurities. It can be cleaned with a detergent and wiped dry with a clean cloth, because impurities may affect the tempering effect or produce adverse reactions at high temperatures. At the same time, carefully check whether the ball screw has any damage or deformation. If so, it needs to be repaired or replaced first.

[0019] Furnace loading: Install the vertical plate and support plate according to the size and shape of the ball screw. To ensure that the ball screw is stably placed in the furnace, the tooling material also needs to have good heat resistance and thermal conductivity to avoid deformation or damage during the tempering process. Place the ball screw in the support groove of the support plate, drive the trolley to move into the tempering chamber, and close the furnace door. According to the tempering process control: accurately control the tempering temperature, generally between 700℃-900℃. Too high temperature may cause problems such as excessive softening of the material and coarse grains, affecting the mechanical properties of the ball screw; too low temperature may result in insufficient tempering and fail to achieve the desired effect.

[0020] The accurate control time should be determined according to the size, material and temperature of the ball screw. Normally, every 10mm thickness needs to be kept warm for about 1h. This is only for reference. In actual operation, it needs to be precisely adjusted through experiments or based on experience.

[0021] Out of the oven: Careful operation is required to avoid deformation of the ball screw due to rapid temperature changes or external forces, and timely cooling is required. Natural cooling or water cooling can be selected according to specific requirements, but attention should be paid to the control of cooling speed. For example, when water cooling is used, the water temperature should not be too low and the water flow rate should not be too fast to prevent excessive temperature difference stress. Finally, some steps such as atmosphere control, impurity cleaning, process monitoring and quality inspection can be carried out to ensure the final product performance.

[0030] In this embodiment, Figure 1-3As shown, the core structure of the trolley 2 type tempering furnace is that it replaces the tooling on the traditional trolley 2 and is composed of a vertical plate 3 and a support plate 4 to ensure that the ball screw is stably placed in the furnace. Specifically, a number of support plates 4 arranged at intervals along the vertical direction are symmetrically arranged on both sides of the vertical plate 3. At the same time, the support grooves 401 on the support plates 4 can make the ball screw evenly heated during the tempering process, allowing heat to circulate, thereby avoiding local overheating or overcooling of the ball screw, thereby ensuring the uniformity of the tempering treatment, improving the quality stability of the ball screw, and stably improving the metallographic structure of the ball screw. Moreover, the support grooves 401 can adapt to ball screws of different specifications and sizes, replacing the traditional fixture form.

During the tempering process, due to the flow of hot air in the furnace, the hot air can also flow in the C shape formed between the vertical plate 3 and the support plate 4, so that it is in full contact with the ball screw, thereby solving the problem of uneven heating.

[0032] The working principle of the trolley 2-type tempering furnace: Cleaning and inspection: Before tempering, it is necessary to ensure that the surface of the ball screw is clean, free of oil, rust and other impurities. It can be cleaned with a detergent and wiped dry with a clean cloth, because impurities may affect the tempering effect or produce adverse reactions at high temperatures. At the same time, carefully check whether the ball screw has any damage or deformation. If so, it needs to be repaired or replaced first.

[0033] Furnace loading: Install the vertical plate 3 and the support plate 4 according to the size and shape of the ball screw. To ensure that the ball screw is stably placed in the furnace, the tooling material also needs to have good heat resistance and thermal conductivity to avoid deformation or damage during the tempering process. Place the ball screw in the support groove 401 of the support plate 4, drive the trolley 2 to move into the tempering chamber 101, and close the furnace door. According to the tempering process control: accurately control the tempering temperature, generally between 700℃-900℃. Too high temperature may cause problems such as excessive softening of the material and coarse grains, affecting the mechanical properties of the ball screw; too low temperature may result in insufficient tempering and fail to achieve the desired effect.

[0034] The accurate control time should be determined according to the size, material and temperature of the ball screw. Normally, every 10mm thickness needs to be kept warm for about 1h. This is only for reference. In actual operation, it needs to be precisely adjusted through experiments or based on experience.

[0035] Out of the oven: Careful operation is required to avoid deformation of the ball screw due to rapid temperature changes or external forces, and timely cooling is required. Natural cooling or water cooling can be selected according to specific requirements, but attention should be paid to the control of cooling speed. For example, when water cooling is used, the water temperature should not be too low and the water flow rate should not be too fast to prevent excessive temperature difference stress. Finally, some steps such as atmosphere control, impurity cleaning, process monitoring and quality inspection can be carried out to ensure the final product performance.

[0036] Furthermore, the vertical plate 3 is arranged in the vertical direction, and a plurality of support plates 4 are arranged at intervals in the vertical direction, and the support plates 4 are swingably arranged on the vertical plate 3 , and the support plates 4 are used to drive the support slots 401 to tilt downward after swinging.

[0037] In this embodiment, Figure 1-3 As shown, the core structure of the trolley 2 type tempering furnace is that it replaces the tooling on the traditional trolley 2 and is composed of a vertical plate 3 and a support plate 4 to ensure that the ball screw is stably placed in the furnace. Specifically, a number of support plates 4 arranged at intervals along the vertical direction are symmetrically arranged on both sides of the vertical plate 3. At the same time, the support grooves 401 on the support plates 4 can make the ball screw evenly heated during the tempering process, allowing heat to circulate and avoiding local overheating or overcooling of the ball screw, thereby ensuring the uniformity of the tempering treatment, improving the quality stability of the ball screw, and stably improving the metallographic structure of the ball screw. Moreover, the support grooves 401 can adapt to ball screws of different specifications and sizes, replacing the traditional fixture form, and only being placed in the groove, or by increasing or reducing the number of vertical plates 3 and support plates 4, it can adapt to the tempering treatment requirements of ball screws of different lengths, and has strong adaptability.

[0038] At the same time, the structure can store a large number of ball screws on both sides of the vertical plate 3 on the trolley 2 and transport them to the furnace body 1, which is more suitable for mass production scenarios and will not affect the overall structural stability and will not collapse, greatly improving space utilization. During the tempering process, due to the flow of hot air in the furnace, the hot air can also flow in the C shape formed between the vertical plate 3 and the support plate 4, so that it is in full contact with the ball screw, thereby solving the problem of uneven heating.

[0039] The working principle of the trolley 2-type tempering furnace: Cleaning and inspection: Before tempering, it is necessary to ensure that the surface of the ball screw is clean, free of oil, rust and other impurities. It can be cleaned with a detergent and wiped dry with a clean cloth, because impurities may affect the tempering effect or produce adverse reactions at high temperatures. At the same time, carefully check whether the ball screw has any damage or deformation. If so, it needs to be repaired or replaced first.

[0040] Furnace loading: Install the vertical plate 3 and the support plate 4 according to the size and shape of the ball screw. To ensure that the ball screw is stably placed in the furnace, the tooling material also needs to have good heat resistance and thermal conductivity to avoid deformation or damage during the tempering process. Place the ball screw in the support groove 401 of the support plate 4, drive the trolley 2 to move into the tempering chamber 101, and close the furnace door. According to the tempering process control: accurately control the tempering temperature, generally between 700℃-900℃. Too high temperature may cause problems such as excessive softening of the material and coarse grains, affecting the mechanical properties of the ball screw; too low temperature may result in insufficient tempering and fail to achieve the desired effect.

[0041] The accurate control time should be determined according to the size, material and temperature of the ball screw. Normally, every 10mm thickness needs to be kept warm for about 1h. This is only for reference. In actual operation, it needs to be precisely adjusted through experiments or based on experience.

[0042] Out of the oven: Careful operation is required to avoid deformation of the ball screw due to rapid temperature changes or external forces, and timely cooling is required. Natural cooling or water cooling can be selected according to specific requirements, but attention should be paid to the control of cooling speed. For example, when water cooling is used, the water temperature should not be too low and the water flow rate should not be too fast to prevent excessive temperature difference stress. Finally, some steps such as atmosphere control, impurity cleaning, process monitoring and quality inspection can be carried out to ensure the final product performance.

[0043] Furthermore, the cross section of the support plate 4 is concave-shaped, and both sides of the support plate 4 have support grooves 401 , and the support grooves 401 are arc-shaped. There are multiple support grooves 401 , and the multiple support grooves 401 are arranged at intervals along the length direction of the support plate 4 .

[0044] In this embodiment, Figure 1-4 As shown, in order to better support the ball screw and avoid collision between the support plate 4 and the ball screw, the support plate 4 is designed to be concave in shape, which can avoid some components on the ball screw and provide stable support at both ends. Therefore, both sides of the support plate 4 have support grooves 401, and several support grooves 401 are arranged along the length of the support plate 4, so that a large number of ball screws can be stored on a group of support plates 4 without being affected by each other.

[0045] Furthermore, the vertical plate 3 has a hollow cavity 301, and the support plate 4 also has a rotating shaft portion 402, which passes through the hollow cavity 301, and also includes: an adjustment plate 5, which is movably set in the hollow cavity 301, and the adjustment plate 5 has a rack 501, and the rotating shaft portion 402 has teeth 403, and the rack 501 is meshed with the teeth 403. After the adjustment plate 5 is subjected to the external force of the swing of the support plate 4, it moves in the hollow cavity 301.

[0046] Furthermore, the moving direction of the adjustment plate 5 is set along the vertical direction, and the top of the hollow cavity 301 has an opening 302, and also includes: a locking cover 6, the locking cover 6 is set at the opening 302, the length of the adjustment plate 5 is equal to the length of the hollow cavity 301, and the locking cover 6 is used to limit the movement of the adjustment plate 5.

[0047] In this embodiment, Figure 1-6 As shown, the support plate 4 is swingably set on the vertical plate 3 through the rotating shaft portion 402 at its end, and a hollow cavity 301 is opened in the vertical plate 3. This is to synchronously adjust the swing of each group of support plates 4 through the adjustment plate 5 moving in the hollow cavity 301. Therefore, the two need to have a connected portion in the hollow cavity 301. The rotating shaft portion 402 penetrates the hollow cavity 301, and then the rack 501 of the adjustment plate 5 can be engaged with the teeth 403 of the rotating shaft portion 402 located in the hollow cavity 301, so that the adjustment plate 5 can move in the hollow cavity 301 after being subjected to the external force of the swing of the support plate 4.

[0048] In the specific use process, it is also necessary to cooperate with the locking cover 6 to limit the movement of the adjustment plate 5 to ensure that each support plate 4 will not shake at will. Therefore, the length of the adjustment plate 5 is equal to the length of the hollow cavity 301, and the top of the hollow cavity 301 has an opening 302. The locking cover 6 is locked at the opening 302 by bolts to achieve the above purpose; when loading the furnace, the locking cover 6 is not installed, and each support plate 4 is in a downward tilted state. At this time, the adjustment plate 5 is under the action of each support plate 4 and the ball screw being equipped, through the rack 501 and the gear The meshing of teeth 403 keeps the adjustment plate 5 in a state where one end thereof moves out of the opening 302. After the equipment is completed, the locking cover 6 is installed to allow the adjustment plate 5 to extend as a whole into and fill the hollow cavity 301, thereby causing each support plate 4 to swing upward until it is perpendicular to the vertical plate 3, stably supporting the ball screw, and then entering the furnace for tempering. After being taken out of the furnace, the process is opposite to the above process. After the product gradually reaches room temperature, the locking cover 6 is slowly removed, and the adjustment plate 5 is slowly tilted downward under the action of each support plate 4 and the ball screw, making it easy for workers to take it away and complete the furnace operation.

[0049] Furthermore, a plurality of vertical plates 3 are arranged at intervals along the moving direction of the trolley 2 , and a plurality of locking covers 6 are provided, and the plurality of locking covers 6 are detachably connected.

[0050] In this embodiment, Figure 1-6As shown, in order to adapt to mass production occasions, several vertical plates 3 are arranged at intervals on the trolley 2, which means that several locking covers 6 must be installed at the same time. This will affect the overall progress and make the operation cumbersome. Therefore, several locking covers 6 are designed to be detachably connected through structures such as through rods. By removing the bolts at both ends of the corresponding several locking covers 6, the overall disassembly can be completed to facilitate subsequent steps.

[0051] Furthermore, the trolley 2 has a plurality of limit strip grooves 201 and slide grooves 202, the slide grooves 202 penetrate the plurality of limit strip grooves 201, the bottom of the vertical plate 3 is slidably set in the slide grooves 202, and also includes: two limit blocks 7, the two limit blocks 7 are both movably set at the bottom of the vertical plate 3, and the two limit blocks 7 are symmetrically set, and the limit blocks 7 extend into or cancel the extension into the limit strip groove 201 after movement, so as to fix the position of the vertical plate 3.

[0052] Furthermore, the length direction of the slide groove 202 is parallel to the moving direction of the trolley 2, and a plurality of limit strip grooves 201 are arranged at intervals along the length direction of the trolley 2, and the length direction of the limit strip grooves 201 is perpendicular to the length direction of the slide groove 202. The bottom of the adjustment plate 5 also has a through hole 303, and the through hole 303 is connected to the hollow cavity 301. The two limit blocks 7 are both movably set in the through hole 303 and are respectively located on both sides of the adjustment plate 5. After the adjustment plate 5 moves, it is used to squeeze the two limit blocks 7 to move.

[0053] Furthermore, the trolley 2 also has a hollow area 203 , and a plurality of limiting strip grooves 201 and slide grooves 202 are all connected to the hollow area 203 . The bottom of the vertical plate 3 also has a bottom plate 304 , and the bottom plate 304 is located in the hollow area 203 .

[0054] In this embodiment, Figure 3-9 As shown, since several vertical plates 3 are arranged at intervals, it means that the installation position needs to be set in advance. In order to make this process simple, easy to operate and without any danger, several limiting strip grooves 201 and slide grooves 202 that penetrate the several limiting strip grooves 201 are opened on the trolley 2. The bottom of the vertical plate 3 is slidably set in the slide groove 202. After sliding to the appropriate position, the limiting blocks 7 on both sides of the bottom of the vertical plate 3 are controlled to move so that they enter the same limiting strip groove 201 in opposite directions, similar to a cross limiting shape, to fix the position of the overall vertical plate 3.

[0055] Specifically, the direction of the slide groove 202 and the limiting strip groove 201 is set to ensure that the position of the subsequent fixed vertical plate 3 is more stable, the cross shape is used, and the entire area of ​​the trolley 2 is fully utilized. In order to prevent the bottom plate 304 at the bottom of the vertical plate 3 from sliding in the hollow area 203 of the trolley 2, the limiting blocks 7 on both sides are blocked, and then a through hole 303 is opened at the bottom of the vertical plate 3. Both sets of limiting blocks 7 are moved and set in the through hole 303 by elastic members. The elastic member provides a force for the limiting blocks 7 to extend into the through hole 303, so that the vertical plate 3 as a whole can slide smoothly in the slide groove 202 when the limiting blocks 7 are not ejected. Only when the position is determined, can the locking cover 6 be installed and the adjusting plate 5 be fully extended into the hollow cavity 301. The two limit blocks 7 are squeezed out of the through holes 303 by the adjusting plate 5 and extend into the limit strip groove 201 to form a cross fixation, thereby completing the locking of the position of the entire vertical plate 3. The bottom plate 304 can also play a role in stabilizing the support of the vertical plate 3 as a whole. At the same time, all the support plates 4 also swing upward, and all the ball screws are stably supported, which is convenient for subsequent furnace loading and tempering operations. Therefore, the hollow area 203 of the trolley 2 also needs to be connected with several limit strip grooves 201 and slide grooves 202 to prevent the vertical plate 3 from being blocked.

Preparation: Clean and check the ball screw for damage or deformation; S2, furnace loading: the ball screw is placed in the support groove 401, the locking cover 6 is installed, the trolley 2 is slowly pushed into the furnace body 1, and the furnace door is closed; S3, annealing and furnace removal: After annealing is completed, wait until the temperature in the furnace is close to room temperature, open the furnace door, slowly push out the trolley 2, remove the ball screw, and clean up the debris and dust in the trolley 2 and the furnace.
