Description

Technical Field

[0001] The present invention belongs to the technical field of turning, and specifically relates to a turning device for processing furnace rolls and its processing technology. Background Art

[0002] In industries such as metallurgy and chemical engineering, slender furnace rolls are widely used as key components, and their processing accuracy directly affects the subsequent production quality. However, due to the slender structural characteristics of the furnace rolls themselves, they are extremely prone to bending deformation under the action of turning force during the turning process, resulting in a decrease in processing accuracy and an increase in the rejection rate.

[0003] Currently, the existing turning devices for processing furnace rolls have obvious deficiencies when dealing with the processing of slender furnace rolls. To solve the problems of supporting and fixing the furnace rolls, the existing devices usually have two independent components. One is used to lift the furnace roll to achieve docking with the fixture, and the other is used to squeeze the furnace roll during the processing to prevent deformation. Although this dual-component design solves some problems to a certain extent, it brings the drawback of complex structure. Too many components not only increase the manufacturing cost of the equipment, but also greatly increase the maintenance difficulty of the equipment. At the same time, the complex structure also reduces the reliability of the equipment operation and is difficult to meet the production requirements of high efficiency and high precision.

[0015] A processing technology of a furnace roll machining and turning device is as follows: Step 1: Loading and positioning of the furnace roll.

Finally, take out the furnace roll, and the equipment resets to prepare for the next processing.

[0016] The present invention has the following beneficial effects compared with the prior art: The pallet of the present invention realizes dual functions. During loading, the pallet enables the operator to easily complete the preliminary positioning without precisely aligning with the fixture, and can also ensure the precise docking of the furnace roll with the fixture when the furnace roll rises with the pallet. During processing, the turntable drives the guide block to push the push plate, and the pallet is driven by mechanical force to squeeze the side wall of the furnace roll with the inner arc wall, forming a dual fixation with the fixture. This design can evenly disperse the turning force and prevent the slender furnace roll from deforming due to single-point stress. The entire structure is only driven by a single drive source to rotate the turntable, and uses mechanical components such as the top block ramp and the guide block to link, without additional power and complex electronic control systems, which not only simplifies the equipment structure, reduces costs, but also reduces the maintenance requirements, enabling the equipment to have stronger reliability and environmental adaptability while ensuring the processing accuracy.

The pushing plate 44 corresponds to a guide block 441 installed on the side wall of the turntable 3, and the installation position of the guide block 441 corresponds to the position of the top block 31. The guide block 441 is used to push the support plate 23 to press against the side wall of the furnace roll to prevent deformation during processing. The design of the slope 311 lifting the push rod 21 can realize the automatic lifting and docking of the furnace roll with the fixture, reducing manual operation; the guide block 441 pushing the support plate 23 to press against the furnace roll can effectively prevent the furnace roll from deforming due to force during processing, ensuring processing accuracy.

[0023] As Figures 1 to 10As shown, in the specific implementation, a base 11 is installed at the bottom of the lathe body 1. The cross-sectional area of the base 11 is larger than that of the bottom of the lathe body 1. A number of pairs of positioning holes 112 for installing bolts are provided on the base 11. A reinforcing rib 111 is installed between the base 11 and the lathe body 1, and the reinforcing rib 111 is triangular. The base 11 increases the contact area between the device and the ground, improving the stability of the device; the positioning holes 112 facilitate the installation and fixation of the device; the triangular reinforcing rib 111 enhances the connection strength between the base 11 and the lathe body 1, making the device more stable during the processing.

[0024] As Figures 1 to 10 shown, further, a partition 121 is installed on the collection bin 12. The partition 121 is used to divide the chamber of the collection bin 12, and the top rod 21 is movably inserted into the partition 121. The partition 121 is in an inclined state, and the inclined partition 121 is used to guide the turning coolant to flow to the return pipe. The partition 121 divides the chamber of the collection bin 12, enabling the orderly arrangement of each component in the collection bin; the inclined partition 121 can guide the turning coolant to flow smoothly to the return pipe, facilitating the recycling and reuse of the coolant, and at the same time keeping the processing environment clean.

[0025] Example 2: Different from the above example in this example: As Figures 1 to 10 shown, a synchronous shaft 321 is installed at the rotation center of the turntable 3. A driving motor 32 is installed at the bottom of the collection bin 12. The output end of the driving motor 32 is connected to the synchronous shaft 321. A guide wheel 211 is installed at the bottom of the top rod 21, and the guide wheel 211 is used to rollingly connect with the top block 31. The driving motor 32 drives the turntable 3 to rotate through the synchronous shaft 321, providing power for the lifting of the furnace roll and the movement of the pallet 23 to achieve automated operation; the rolling connection between the guide wheel 211 and the top block 31 can reduce the friction between the top rod 21 and the top block 31, making the movement of the top rod 21 smoother and extending the service life of the components.

[0026] As Figures 1 to 10As shown, in the specific implementation, a bending frame 22 is installed on the synchronization plate 2. A limit seat 421 is installed on the side wall of the bending frame 22, and the limit seat 421 is movably inserted into the connecting plate 42. The end of the bending frame 22 is connected to the bottom of the positioning seat 221. The inner side wall of the positioning seat 221 is arc-shaped, and a limit guide rail 222 is installed on the positioning seat 221. A limit chute 223 is opened at the bottom of the support plate 23. Both the limit chute 223 and the limit guide rail 222 are arc-shaped, and the limit guide rail 222 slides in the limit chute 223. A number of pairs of balls 231 are installed on the support plate 23. The connection between the bending frame 22 and the positioning seat 221 enhances the structural stability between the synchronization plate 2 and the positioning seat 221; the arc-shaped inner side wall of the positioning seat 221 is adapted to the outer contour of the furnace roller, which can better support the furnace roller; the cooperation between the limit guide rail 222 and the limit chute 223 makes the sliding trajectory of the support plate 23 more accurate, ensuring that the furnace roller accurately moves to the fixture; the balls 231 reduce the friction between the furnace roller and the support plate 23, facilitating the placement and movement of the furnace roller, and at the same time reducing the wear on the surface of the furnace roller.

[0027] As Figures 1 to 10 shown, further, a fixing plate 232 is installed on the side wall of the support plate 23. A guide rod 233 is installed on the fixing plate 232, and the guide rod 233 is arc-shaped. The guide rod 233 is movably inserted into the positioning seat 221. A tension spring 234 is sleeved on the guide rod 233. One end of the tension spring 234 is clamped on the side wall of the fixing plate 232, and the other end is clamped on the side wall of the positioning seat 221. The guide rod 233 is arc-shaped and matches the sliding trajectory of the support plate 23, guiding the movement of the support plate 23; the tension spring 234 can automatically reset the support plate 23 after it moves, facilitating the placement of the furnace roller during the next processing and improving the processing efficiency.

[0028] As Figures 1 to 10 shown, further, an insertion plate 24 is vertically penetrated through the partition plate 121. The top of the insertion plate 24 is connected to the side wall of the synchronization plate 2, and a sliding plate 241 is installed at the bottom of the insertion plate 24. A positioning rod 242 is movably penetrated through the sliding plate 241. The bottom of the positioning rod 242 is installed at the bottom of the collection bin 12, and the top of the positioning rod 242 is installed at the bottom of the partition plate 121. A positioning spring 243 is sleeved on the positioning rod 242. One end of the positioning spring 243 is clamped on the sliding plate 241, and the other end is clamped on the inner wall of the partition plate 121. The insertion plate 24 moves with the synchronization plate 2, preventing the coolant from leaking from the gap between the synchronization plate 2 and the partition plate 121; the cooperation between the sliding plate 241 and the positioning rod 242 makes the movement of the insertion plate 24 more stable.

[0029] Example 3: Different from the above example in this example: As Figures 1 to 10As shown, a positioning sleeve 4 is installed at the end of the connecting plate 42. A slider 412 is slidably arranged inside the positioning sleeve 4, and a pulling plate 41 is installed on the slider 412. The pulling plate 41 is movably inserted into the positioning sleeve 4, and the end of the pulling plate 41 is rotatably connected to a positioning post 411 installed on the side wall of the support plate 23. A sliding rod 413 is vertically and penetratingly installed inside the positioning sleeve 4, and the sliding rod 413 movably penetrates through the slider 412 and the pulling plate 41. A guiding spring 414 is sleeved on the sliding rod 413. One end of the guiding spring 414 is clamped on the side wall of the positioning sleeve 4, and the other end of the guiding spring 414 is clamped on the bottom of the slider 412. The linkage structure composed of the positioning sleeve 4, the slider 412, the pulling plate 41, the sliding rod 413, etc. can transmit the thrust of the push plate 44 to the support plate 23, causing the support plate 23 to rotate and press against the side wall of the furnace roll.

[0030] As Figures 1 to 10 shown, in the specific implementation manner, a notch 432 with a length greater than the outer diameter of the telescopic rod 43 is opened on the partition plate 121, and the telescopic rod 43 slides in the notch 432. A sealing plate 431 is installed on the telescopic rod 43, and the sealing plate 431 slides on both sides of the partition plate 121, and the sealing plate 431 is used to block the notch 432. A protrusion 442 is installed on the push plate 44, and the protrusion 442 fits with the guiding block 441. The notch 432 provides space for the sliding of the telescopic rod 43; the sealing plate 431 blocks the notch 432, which can prevent the coolant from leaking from the notch, ensuring the cleanliness of the processing environment and the recycling of the coolant; the protrusion 442 fits with the guiding block 441, which can make the push plate 44 be better pushed by the guiding block 441, ensuring the accuracy of the action of the support plate 23 pressing the furnace roll.

[0031] The present invention also discloses a processing technology for a turning device for processing furnace rolls, and the steps are as follows: Step 1: Loading and positioning of the furnace roll. Place the slender furnace roll on the support plate 23. The balls 231 of the support plate 23 can reduce friction, and it can be initially placed without precisely aligning with the fixture. Step 2: Lifting and docking the furnace roll with the fixture. Start the driving motor 32 to drive the turntable 3 to rotate. The top block 31 on the turntable 3 jacks up the ejector rod 21 through the slope 311, so that the synchronous plate 2 drives the support plate 23 to rise along an arc trajectory, send the furnace roll to the fixture of the lathe body 1, and push the furnace roll into the fixture and initially fix it. Step 3: Double fixation and turning preparation. The turntable 3 continues to rotate. The guiding block 441 pushes the push plate 44, drives the connecting plate 42 through the telescopic rod 43, and makes the positioning sleeve 4 and the pulling plate 41 pull the support plate 23 to press the furnace roll, and fix the furnace roll together with the fixture. Step 4: Turning processing and support. After the lathe is started, the main shaft drives the furnace roll to rotate, the turning tool performs turning, the inner side wall of the support plate 23 fits with the furnace roll to disperse the turning force, the balls 231 maintain low friction to make the furnace roll rotate smoothly, and the sealing plate 431 will block the notch 432 of the partition plate 121 to prevent the coolant from leaking out. Step Five: Reset and Cleaning. After processing, the drive motor 32 rotates in reverse, the ejector rod 21 descends to drive the pallet 23 back to the bottom. The pallet 23 resets under the action of the tension spring 234. Finally, the furnace roll is taken out, and the equipment resets to prepare for the next processing.

[0032] The implementation principle of a turning device for processing furnace rolls of the present invention is as follows: First, the operator steadily places the slender furnace roll on the pallet 23. A number of pairs of ball bearings 231 on the pallet 23 can reduce the friction when the furnace roll is placed, facilitating accurate positioning. Subsequently, the drive motor 32 is started, and its output end is connected to the synchronizing shaft 321, thereby driving the synchronizing shaft 321 to rotate. The rotation of the synchronizing shaft 321 further causes the turntable 3 to rotate at the bottom of the collection bin 12. The top block 31 installed on the turntable 3 rotates together with the turntable 3, and the top block 31 is provided with a slope 311. When the top block 31 rotates to contact the guide wheel 211 at the bottom of the ejector rod 21, due to the action of the slope 311, the ejector rod 21 will be jacked up. The ejector rod 21 is connected to the bottom of the synchronizing plate 2, so the upward movement of the ejector rod 21 will drive the synchronizing plate 2 to move vertically upward inside the collection bin 12. Positioning seats 221 are installed on both sides of the synchronizing plate 2, and the pallet 23 is slidably installed on the positioning seats 221. The pallet 23 is used to support the furnace roll. When the synchronizing plate 2 moves upward, the pallet 23 moves upward accordingly, thereby moving the furnace roll to the fixture position of the lathe body 1. A limiting chute 223 is provided at the bottom of the pallet 23, and a limiting guide rail 222 is installed on the positioning seat 221, and both are arc-shaped. Such a design enables the pallet 23 to move along an arc trajectory during the sliding process, ensuring that the furnace roll accurately moves to the fixture. At the same time, a number of pairs of ball bearings 231 installed on the pallet 23 can reduce the friction between the furnace roll and the pallet 23, facilitating the movement and positioning of the furnace roll. Push the furnace roll to slide horizontally, insert the furnace roll into the fixture of the lathe body, and then lock and fix the furnace roll through the locking mechanism of the fixture to ensure that the furnace roll remains stable during processing and does not displace or shake. As the turntable 3 continues to rotate, finally, the guide block 441 will contact the push plate 44 and generate a thrust. The push plate 44 and the connecting plate 42 form a linkage structure through the telescopic rod 43. When the push plate 44 is pushed by the guide block 441, the telescopic rod 43 will slide in the notch 432, and at the same time drive the connecting plate 42 to move towards the furnace roll. The end of the connecting plate 42 drives the pallet 23 to have a sliding force through the positioning sleeve 4 and the pull plate 41, and then drives the constrained pallet 23 to slide along the limiting guide rail 222. At this time, the inner side wall of the pallet 23 will tightly squeeze the side wall of the furnace roll, effectively preventing the furnace roll from deforming or displacing due to force during turning processing.

[0033] Among them, the above-mentioned pallet 23 can not only support the furnace roll, enabling the operator to simply place the furnace roll directly on the pallet to complete the preliminary positioning without precisely aligning with the fixture; at the same time, during the machining process, the extrusion of the inner side wall of the rotating pallet 23 on the side wall of the furnace roll enhances the rigidity of the furnace roll and effectively resists the deformation caused by the turning force.

[0034] After the above operations are completed, the operator starts the lathe body 1, and the lathe spindle drives the furnace roll to rotate, and the turning tool performs turning machining on the surface of the furnace roll. At this time, the pallet 23 continuously maintains radial support for the furnace roll, and the arc surface of its inner side wall fits with the furnace roll, dispersing the turning force to the positioning seat 221 and the synchronous plate 2 to avoid deformation due to single-point stress. The inclined partition 121 in the collection bin 12 guides the turning coolant to flow along the slope towards the return pipe. When the plug board 24 on the partition 121 moves with the synchronous plate 2, the sliding plate 241 slides on the positioning rod 242, and the positioning spring 243 buffers the vibration to ensure the stability of the coolant diversion path. After the machining is completed, the drive motor 32 rotates in reverse, the turntable 3 drives the top block 31 to reset, the ejector rod 21 descends along the slope 311 under the action of gravity, and the synchronous plate 2 drives the pallet 23 to fall back.
