Description

Technical Field

[0001] The invention relates to the technical field of zinc pot roller milling, in particular to zinc pot roller surface groove machining equipment. Background Art

[0002] The zinc pot roller is a key component in the continuous hot-dip galvanizing production line. The sinking roller is immersed in high-temperature zinc liquid for a long time and is responsible for guiding the strip to turn and controlling the thickness of the zinc layer. Due to the relative motion between the strip and the sinking roller, and the zinc liquid has a certain fluidity and viscosity, in order to ensure that the strip can maintain a stable friction between the strip and the sinking roller, prevent the strip from slipping on the roller surface, and effectively remove excess zinc liquid and harmful zinc slag at the angle between the strip and the roller surface, it is usually necessary to process spiral grooves of specific shape and size on the roller surface.

[0003] At present, the grooves of the sinking roller are mainly processed by CNC milling machines. Under the control of the CNC program, the forming tools of the milling cutter group are used to perform precise milling on the surface of the sinking roller rotating at a low speed. The milling cutter group is fed axially along the surface of the sinking roller to implement the milling process of the grooves on the surface of the sinking roller. Due to the deep and narrow structure of the groove, it cannot be milled in one time and needs to be completed step by step through multiple layered milling. During the processing, coolant is continuously sprayed to reduce the cutting temperature and wash away the debris.

[0004] The following problems exist in the existing milling process of the sinking roller surface: in the layered milling of the sinking roller, the debris generated in the previous process is easy to remain on the side walls and bottom of the groove. The debris is driven by the coolant flowing downward along the surface of the sinking roller under the action of gravity. The cleaning power of the coolant may be insufficient, affecting the cleaning effect of the debris in the groove on the surface of the sinking roller. Especially when the groove is deep and narrow, there may be a cleaning dead zone in the groove on the surface of the sinking roller, resulting in the coolant being unable to completely clean the debris in the groove on the surface of the sinking roller, and then a large amount of debris still remains in the groove on the surface of the sinking roller. In subsequent milling, the debris causes the groove surface to be scratched by the debris, affecting the processing quality of the groove. Summary of the Invention

[0030] The embodiments described below are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product instructions shall be followed.

[0031] See Figure 1 A zinc pot roller surface groove machining device includes a milling machine 1, the milling machine 1 includes a milling cutter group 11, a flushing unit 2 is installed on the milling cutter group 11, and a cleaning unit 3 is installed on the flushing unit 2. The flushing unit 2 and the cleaning unit 3 are both located on the right side of the milling processing position of the milling cutter group 11.

[0032] It should be noted that the milling machine 1 adopts the existing technology, which also includes a machine base 12, a clamping group 13, a spindle group 14 and a cooling group (not shown in the figure). The clamping group 13 is arranged on the left side of the upper end of the machine base 12, and adopts a three-jaw chuck to center and clamp the mounting shaft at the left end of the sinking roller. The spindle group 14 is arranged on the right side of the upper end of the machine base 12, and is used to fix the mounting shaft at the right end of the sinking roller to cooperate with the clamping group 13 to clamp and fix the sinking roller, and the spindle group 14 can also drive the sinking roller to rotate at a low speed. The milling cutter group 11 is arranged on the upper end of the machine base 12 and is located at the clamping group 13. Between the spindle group 14, by replacing the tool of the milling cutter group 11 and controlling the axial feed of the milling cutter group 11 along the surface of the sinking roller, the milling cutter group 11 mills a groove of a specific shape on the surface of the sinking roller rotating at a low speed. The cooling group is set at the corresponding position of the milling cutter group 11. When the milling cutter group 11 mills the surface of the sinking roller, the cooling group sprays the coolant to the corresponding milling processing area of ​​the sinking roller surface through the coolant nozzle, thereby reducing the milling temperature and allowing the coolant to flow downward along the surface of the sinking roller under the action of gravity, so as to preliminarily clean the debris on the surface of the sinking roller.

[0033] The present invention is used for milling grooves on the surface of the sinking roller, and the flushing unit 2 of the present invention can collect coolant and flush the surface of the sinking roller after milling, and the flushing force of the coolant increases the cleaning force of the debris in the grooves on the surface of the sinking roller, thereby ensuring the cleaning effect of the coolant on the debris in the grooves on the surface of the sinking roller. At the same time, the cleaning unit 3 of the present invention adopts a combination of bristle cleaning and airflow cleaning to implement deep cleaning of the debris in the grooves on the surface of the sinking roller, thereby improving the cleaning effect of the debris in the deeper and narrower grooves, reducing the debris residue in the grooves, and reducing the probability of the debris scratching the groove surface again, thereby ensuring the processing quality of the grooves on the surface of the sinking roller.

[0034] Specifically, first, the sinking roller is clamped and fixed by the clamping group 13 and the spindle group 14, and the spindle group 14 is controlled to drive the sinking roller to rotate at a low speed, and then the milling cutter group 11 is controlled to feed axially along the surface of the sinking roller from right to left, and the surface of the sinking roller is milled. At the same time, the cooling group is synchronously controlled to continuously spray coolant, and the milling cutter group 11 drives the flushing unit 2 and the cleaning unit 3 to move from right to left. When the coolant flows from top to bottom along the surface of the sinking roller, the flushing unit 2 can collect the coolant and flush the grooves on the surface of the sinking roller, and at the same time, the cleaning unit 3 is started to use The grooves on the surface of the sinking roller are cleaned by combining bristle cleaning and air flow cleaning, thereby achieving deep cleaning of the grooves. When the milling cutter group 11 moves to the left limit position and completes one milling process on the surface of the sinking roller, the milling cutter group 11 is reset, and the milling cutter group 11 is controlled again to feed axially from right to left along the surface of the sinking roller to implement multi-layer milling of the grooves on the surface of the sinking roller. When the milling process of the sinking roller is completed, the clamping group 13 and the spindle group 14 are controlled to loosen the sinking roller, and the sinking roller is taken out to achieve milling of the grooves on the surface of the sinking roller.

[0035] See Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The flushing unit 2 includes a mounting plate 21 arranged on the milling cutter group 11, and a reciprocating plate 23 is installed on the upper end of the mounting plate 21 for sliding left and right through a reciprocating member 22. A collecting bucket 25 is rotatably installed on the rear side of the upper end of the reciprocating plate 23 through a mounting frame 24, and the mounting frame 24 is located on the rear side of the collecting bucket 25. A flushing group 26 is installed on the reciprocating member 22 and on the front side below the collecting bucket 25; the upper end of the collecting bucket 25 is set to rubber material.

[0036] It should be noted that the reciprocating member 22 includes a threaded rod and a drive motor. The threaded rod is connected to the reciprocating plate 23 by threaded fitting, and the threaded rod is rotatably connected to the mounting plate 21. The right end of the threaded rod is fixedly connected to the output shaft of the drive motor, and the drive motor is fixedly installed at the right end of the mounting plate 21. By controlling the drive motor to drive the threaded rod to rotate back and forth, the threaded rod drives the reciprocating plate 23 to move back and forth left and right.

[0037] The flushing unit 2 is mainly used to collect the coolant and flush the grooves on the surface of the sinking roller. Specifically, the milling cutter group 11 drives the collecting bucket 25 to move synchronously from right to left along the axial direction of the sinking roller through the mounting plate 21. At the same time, the reciprocating member 22 is started to drive the collecting bucket 25 to move from right to left along the axial direction of the sinking roller through the reciprocating plate 23. When the coolant flows from top to bottom along the surface of the sinking roller and moves out of the surface of the sinking roller, the collecting bucket 25 can collect the coolant. When the reciprocating plate 23 moves to the left extreme position, the flushing group 26 impacts the collecting bucket upward. The lower side of the front end of the bucket 25 makes the collecting bucket 25 rotate upward quickly based on the rotating connection between it and the mounting frame 24, so that the collecting bucket 25 drives the coolant inside it to splash onto the surface groove of the sinking roller with a certain force, so that the coolant flushes the surface groove of the sinking roller and increases the cleaning force of the coolant on the surface groove of the sinking roller, thereby ensuring the cleaning effect of the debris in the surface groove of the sinking roller, and the upper end of the collecting bucket 25 is set to rubber material, so that the collecting bucket 25 will not rigidly hit the sinking roller and affect the milling processing of the surface groove of the sinking roller.

[0038] It should be noted that although the flushing coolant also contains debris, the rapid flushing force can greatly reduce the amount of debris in the groove of the sinking roller, and only a small amount of debris remains on the groove surface.

[0039] See Figure 2 and Figure 5 The flushing group 26 includes a mounting seat 261 fixedly mounted on the front side of the upper end of the reciprocating plate 23. A flushing top plate 263 is mounted on the upper end of the mounting seat 261 for sliding up and down through a plurality of top extension springs 262. When the flushing top plate 263 is in the lower limit (initial) position, its upper end is in contact with the lower side of the collecting bucket 25; the upper end of the flushing top plate 263 is set to be arc-shaped.

[0040] See Figure 2 、 Figure 3 and Figure 4 A lower pressure rod 264 is fixedly installed on the middle part of the front end of the flushing top plate 263, and the lower pressure rod 264 is located above the mounting seat 261. A lower pressure plate 212 is fixedly installed on the front side of the upper end of the mounting plate 21 through multiple L-shaped connecting rods 211, and the left end of the lower pressure plate 212 is arranged to tilt upward.

[0041] See Figure 3 、 Figure 4 and Figure 5, a plurality of elastic locking rods 265 evenly arranged left and right are installed on the upper side of the front end of the mounting seat 261 for sliding forward and backward, a round rod 266 is fixedly installed on the front end of the elastic locking rod 265, and the front ends of the plurality of round rods 266 slide forward and backward through the mounting seat 261 and are jointly fixed with an unlocking plate 267, and a matching rod 268 is fixedly installed on the middle part of the lower end of the unlocking plate 267. A plurality of locking holes corresponding to the elastic locking rods 265 are opened at the front end of the flushing top plate 263. When the flushing top plate 263 is in the lower limit position, the elastic locking rods 265 are inserted into the corresponding locking holes to lock the flushing top plate 263.

[0042] See Figure 3 An L-shaped mating plate 213 is fixedly installed on the front side of the upper end of the mounting plate 21, and the right side of the front end of the transverse section of the mating plate 213 is set as a slope. When the mating rod 268 moves to the left limit position, the slope of the mating plate 213 and the mating rod 268 cooperate to drive the unlocking plate 267 to move forward. When the flushing top plate 263 is ejected, the lower pressure rod 264 does not contact the lower pressure plate 212. Therefore, when the flushing top plate 263 is quickly and instantaneously ejected, the lower pressure rod 264 will not collide and interfere with the lower pressure plate 212.

[0043] See Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the flushing group 26 is used to drive the collecting bucket 25 to flip quickly so that the coolant collected by it flushes the grooves on the roller surface; specifically, initially, the reciprocating plate 23 is in the right limit position, the flushing top plate 263 is in the lower limit position, and the extension spring 262 is in a compressed state. At this time, the elastic locking rod 265 is inserted into the corresponding locking hole, so that the flushing top plate 263 is in a locked state. When the reciprocating plate 23 moves to the left, the reciprocating plate 23 drives the mounting seat 261 to move to the left. When the mounting seat 261 drives the matching rod 268 to move to the left to the inclined surface of the transverse section of the matching plate 213 and continues to move to the left, the inclined surface of the transverse section of the matching plate 213 pushes the matching rod 268 Moving forward, the cooperating rod 268 drives the elastic locking rod 265 to move forward out of the corresponding locking hole through the unlocking plate 267 and the round rod 266, thereby releasing the lock on the flushing top plate 263. At the same time, the elastic locking rod 265 is compressed and its rear end is always pressed against the front end of the flushing top plate 263. Under the elastic action of the extension spring 262, the flushing top plate 263 moves upward rapidly and impacts the front side of the lower end of the collecting bucket 25, causing the collecting bucket 25 to rotate upward rapidly based on the rotating connection between it and the mounting frame 24, so that the collecting bucket 25 drives the coolant inside it to be splashed onto the surface groove of the sinking roller with a certain force, so that the coolant flushes the surface groove of the sinking roller.

[0044] When the reciprocating plate 23 moves to the right from the left limit position, the reciprocating plate 23 drives the flushing top plate 263 to move to the right through the mounting seat 261. When the flushing top plate 263 drives the lower pressure rod 264 to move to contact the lower side of the lower pressure plate 212 and continues to move to the right, the inclined structure of the lower pressure plate 212 pushes the lower pressure rod 264 to move downward, so that the lower pressure rod 264 drives the flushing top plate 263 to move downward and compress the extension spring 262. At the same time, the lower side of the collecting bucket 25 always rests against the upper end of the flushing top plate 263 under the action of gravity. When the flushing top plate 263 moves to the lower limit position, the locking hole of the flushing top plate 263 moves to the corresponding The elastic locking rod 265 is in the corresponding position, and the elastic locking rod 265 is inserted into the corresponding locking hole again under its elastic action to lock the flushing top plate 263. When the reciprocating plate 23 moves to the left limit position again, the flushing top plate 263 can impact the front side of the lower end of the collecting bucket 25 upward again, so that the collecting bucket 25 can continue to collect the coolant and flush the grooves on the surface of the sinking roller; after the flushing top plate 263 is quickly and instantaneously ejected, the upper end height of the lower pressure rod 264 is slightly lower than the highest point of the left end of the inclined arrangement of the lower pressure plate 212, ensuring that the lower pressure rod 264 can contact the lower side surface of the lower pressure rod 264 during the locking operation.

[0045] It should be specially noted that the flushing unit 2 designed in the present invention has a rapid reciprocating flipping and flushing function. Compared with the traditional flipping mechanism (such as the existing motor directly flipping forward and reverse or other reciprocating flipping mechanisms), its main function is to use the instantaneous impact force of the extension spring 262 in a compressed state to quickly eject the collection bucket 25, so that the collection bucket 25 can drive the coolant collected therein and the coolant that continues to flow downward to quickly flush the grooves on the surface of the sinking roller, and this flushing is carried out in a reciprocating cycle. The instantaneous rapid flushing effect achieved by the present invention is unattainable by all existing technologies. At the same time, this is also the technical purpose of our design of the cyclic unlocking and locking structure.

[0046] See Figure 1 、 Figure 2 、 Figure 7 and Figure 8 The cleaning unit 3 includes an arc-shaped plate 31 fixedly mounted on the rear end of the mounting frame 24, an active group 32 is mounted on the arc surface of the arc-shaped plate 31, and an air collecting cylinder 33 which reciprocates along an arc trajectory is mounted on the active group 32, a compression group 34 is connected between the air collecting cylinder 33 and the active group 32, and a hard brush 333 is provided on the end of the air collecting cylinder 33 away from the arc-shaped plate 31, and a plurality of air outlet holes 334 are opened, and a lifting group 35 is mounted on the arc-shaped plate 31; the active group 32 includes an arc-shaped electric slider assembly 321 fixedly mounted on the arc surface of the arc-shaped plate 31 by a plurality of fixing blocks, an arc-shaped connecting plate 322 is fixedly mounted on the arc-shaped electric slider assembly 321, and the air collecting cylinder 33 is radially slidably connected to the arc surface of the connecting plate 322 by a plurality of guide rods 331 evenly arranged in the circumference; refer to FIG. Figure 6 A reinforcing plate is connected between the arc-shaped plate 31 and the mounting frame 24 to increase the structural stability thereof.

[0047] The cleaning unit 3 uses a combination of bristle cleaning and air flow cleaning to implement deep cleaning of the debris in the grooves on the surface of the sinking roller; specifically, when the milling cutter group 11 drives the mounting plate 21 to move from right to left along the axial direction of the sinking roller, the mounting plate 21 eventually drives the air collecting cylinder 33 to move from right to left along the axial direction of the sinking roller through the reciprocating plate 23. When the air collecting cylinder 33 moves to the corresponding position of the sinking roller axis, the hard bristles 333 are in contact with the surface of the sinking roller. When the reciprocating plate 23 moves back and forth left and right, the reciprocating plate 23 eventually drives the air collecting cylinder 33 to move back and forth left and right through the mounting frame 24. The arc-shaped electric slider assembly 321 is started to drive the air collecting cylinder 33 to move back and forth along the arc trajectory through the connecting plate 322 and the guide rod 331, so that the air collecting cylinder 33 drives the hard bristles 333 to move back and forth left and right and reciprocate along the arc trajectory, so that the hard bristles 333 clean the grooves on the surface of the sinking roller.

[0048] When the air collecting cylinder 33 moves downward along the arc trajectory, the lifting group 35 drives the air collecting cylinder 33 to move radially away from the connecting plate 322 under the action of the guide rod 331, so that the air collecting cylinder 33 is close to the sinking roller, increasing the contact pressure between the hard bristles 333 and the grooves on the surface of the sinking roller, thereby increasing the cleaning force on the grooves on the surface of the sinking roller, and making the hard bristles 333 deeply clean the grooves on the surface of the sinking roller. When the air collecting cylinder 33 moves downward along the arc trajectory to the lower limit position, the compression group 34 sprays the air in the air collecting cylinder 33 to the grooves on the surface of the roller through the air outlet 334, and implements airflow cleaning of the debris in the grooves on the surface of the sinking roller, thereby realizing deep cleaning of the debris in the grooves on the surface of the sinking roller by combining bristle cleaning and airflow cleaning, improving the cleaning effect of debris in deeper and narrower grooves, thereby reducing the residual debris in the grooves, and determining the processing quality of the grooves on the surface of the sinking roller.

[0049] See Figure 2 、 Figure 6 and Figure 8 A lifting rod 332 is fixedly installed on the front side of the gas collecting cylinder 33. The lifting group 35 includes an L-shaped plate 351 fixedly installed on the right side of the arc surface of the arc-shaped plate 31. An arc-shaped fixing plate 352 is fixedly installed on the left end of the transverse section of the L-shaped plate 351. A lifting plate 353 is fixedly installed on the front side of the arc surface of the fixing plate 352. The upper end of the lifting plate 353 is provided with an inclined surface that cooperates with the lifting rod 332; the front end of the lifting plate 353 and the arc plate 31 are both set as inclined surfaces, and the inclined surfaces of the lifting plate 353 and the arc plate 31 are used to drive the lifting rod 332 to move downward along the axial direction of the gas collecting cylinder 33.

[0050] See Figure 7The compression group 34 includes a compression plate 341 that is slidably installed in the air collecting cylinder 33 along the axial direction of the air collecting cylinder 33. The compression plate 341 is connected to the air collecting cylinder 33 through a connecting spring 342. A fixing rod 343 is fixedly installed on one end of the compression plate 341 close to the connecting plate 322. The end of the fixing rod 343 close to the connecting plate 322 slides through the air collecting cylinder 33 and is fixedly connected to the connecting plate 322.

[0051] See Figure 2 、 Figure 6 、 Figure 7 and Figure 8 The lifting group 35 is used to increase the cleaning force of the hard bristles 333 on the grooves on the surface of the sinking roller; specifically, when the arc-shaped electric slider assembly 321 drives the air collecting cylinder 33 to move downward along the arc trajectory, the air collecting cylinder 33 drives the lifting rod 332 to move downward along the arc trajectory, and when the lifting rod 332 moves to contact the upper end inclined surface of the lifting plate 353 and continues to move, the lifting rod 332 drives the air collecting cylinder 33 to move radially away from the connecting plate 322 under the push of the inclined surface of the lifting plate 353, and compresses the connecting spring 342, so that the air collecting cylinder 33 is close to the sinking roller, increasing the contact pressure between the hard bristles 333 and the grooves on the surface of the sinking roller, thereby increasing the cleaning force on the grooves on the surface of the sinking roller.

[0052] When the arc-shaped electric slider assembly 321 drives the air collecting cylinder 33 to move to the lower limit position along the arc trajectory, the lifting rod 332 and the lifting plate 353 are separated, and under the elastic action of the connecting spring 342, the air collecting cylinder 33 moves rapidly radially toward the connecting plate 322, so that the compression plate 341 compresses the air between it and the air collecting cylinder 33, and the air is ejected into the groove on the surface of the roller through the air outlet 334, thereby implementing airflow cleaning of the debris in the groove on the surface of the sunken roller, wherein the airflow cleaning mainly plays an auxiliary cleaning role, and the main cleaning of the debris in the groove is still the cleaning of the hard bristles 333.

[0053] When the arc-shaped electric slider assembly 321 drives the gas collecting cylinder 33 to move upward along the arc-shaped trajectory, the gas collecting cylinder 33 drives the lifting rod 332 to move upward along the arc-shaped trajectory. When the lifting rod 332 moves to contact the left end inclined surface of the lifting plate 353 and continues to move, the lifting rod 332 is pushed by the front end inclined surface of the lifting plate 353 and moves to the front end inclined surface of the arc plate 31, and continues to move to the lower arc surface of the arc plate 31 under the push of the front end inclined surface of the arc plate 31. Then the lifting rod 332 continues to move along the lower arc surface of the arc plate 31. When the gas collecting cylinder 33 moves upward along the arc-shaped trajectory to the initial position, the lifting rod 332 and the arc plate 31 separate and move to the initial position, so that the gas collecting cylinder 33 can continue to move back and forth along the arc-shaped trajectory.

[0054] The present invention flushes the grooves on the surface of the sinking roller through the flushing unit 2, so that most of the debris in the grooves is flushed, and only a small amount of residual debris remains in the grooves; on the basis of the flushing of the flushing unit 2, the debris in the grooves is further cleaned with the help of the hard bristles 333 of the air collecting cylinder 33 on the cleaning unit 3 and the air flow cleaning, which greatly reduces the probability of the debris scratching the groove surface again, thereby ensuring the processing quality of the grooves on the surface of the sinking roller and achieving the technical purpose.
