Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal processing, and particularly relates to an intelligent control metal calendered steel strip slitting machine. BACKGROUND

[0002] The steel strip usually needs to be continuously rolled by a five-stand cold continuous rolling mill to form a calendered steel strip, and then the calendered steel strip is cut into steel strips of different widths by a circular cutter on a slitting machine. In the prior art, there is a circular cutter made of an alloy material, which has a shape of a circular ring, a large material hardness and a sharp edge, and can reduce the generation of burrs when cutting the steel strip, and is thus commonly used for slitting processing of the calendered steel strip. However, in the cutting process, only one side of the cutting edge of the circular cutter continuously cuts the steel strip, which easily causes uneven wear of the two side edges of the circular cutter, so that the circumferential ring surface of the cutter cannot be closely attached to the surface of the steel strip, and burrs are generated at the cutting edge, thereby reducing the cutting quality of the steel strip.

[0003] In summary, the present application provides an intelligent control metal calendered steel strip slitting machine to improve the above-mentioned technical problems. SUMMARY

Detailed Implementation

[0031] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0032] Example 1: As Figures 1-11 As shown, an intelligent control metal rolling strip slitting machine includes a base frame 1;

Each cutter shaft 3 is fixedly connected to an external power unit, which drives the cutter shaft 3 to rotate. Each cutter shaft 3 is equipped with five eccentric self-locking bottom round cutters 3001. The eccentric self-locking bottom round cutters 3001 can slide on the cutter shaft 3. Each eccentric self-locking bottom round cutter 3001 has an eccentric groove inside, and a round key 3002 is slidably connected to each eccentric groove. Each cutter shaft 3 has a through-hole keyway 3004. Each round key 3002 slides within its corresponding keyway 3004. Rotating the eccentric self-locking bottom circular cutter 3001 causes the circular key 3002 to slide within the eccentric groove, thereby pressing the keyway 3002 against the keyway 3004 and locking the eccentric self-locking bottom circular cutter 3001. A limiting block 3003 is provided on the left side of each eccentric self-locking bottom circular cutter 3001. The steel strip 5 passes between the upper and lower eccentric self-locking bottom circular cutters 3001. A drive assembly is mounted on the base frame 1.

[0034] The drive assembly includes a first drive component 201, a connecting frame 202, a rotating frame 203, a motor 204, a second drive component 205, and a third drive component 206. Four rectangularly arranged guide rails are fixedly connected to the base frame 1. Each guide rail has a first drive component 201 slidably connected to it; the first drive component 201 is an electric slider. A connecting frame 202 is mounted on each of the two front first drive components 201 and the two rear first drive components 201.

[0035] In the clamping plate assembly connected to the rotating frame 203 located on the upper front side, a partition plate 4002 is provided on the right roller 4001; the diameter of the partition plate 4002 is larger than the diameter of the roller 4001.

[0036] To extend the service life of the 4002 separator, the 4002 separator is made of high-speed steel with good wear resistance and high hardness.

[0037] It also includes a linkage rod 301; a linkage rod 301 is fixed at the center of the left roller 4001 in each clamping plate assembly, and the linkage rod 301 passes through the right roller 4001; a groove 30101 is provided on each linkage rod 301; a protrusion corresponding to the shape of the groove 30101 is provided at the center of the right roller 4001 in each clamping plate assembly.

[0038] It also includes a sponge sleeve 302, a rotary joint 303, and a connecting pipe 304; each linkage rod 301 is wrapped with a sponge sleeve 302; each linkage rod 301 is hollow and has several liquid outlet holes 30102; the linkage rod 301 passes through the adjacent clamping plate 4; in the clamping plate group connected to the rotating frame 203 located on the upper front side, each clamping plate group has a rotary joint 303 fixedly connected to the clamping plate 4 on the left side; each rotary joint 303 is rotatably connected to the adjacent linkage rod 301, and the interior of the rotary joint 303 communicates with the interior cavity of the adjacent linkage rod 301; each rotary joint 303 is connected to a connecting pipe 304; the connecting pipe 304 is connected to an external oil supply device.

[0039] The opposing surfaces of the two rollers 4001 in the same clamping plate assembly are covered with an oil-absorbing layer made of polyurethane foam.

[0040] The connecting pipe 304 is a corrugated flexible hose.

[0041] The 302 sponge sleeve is made of high-hardness polyurethane foam material to improve its compressive strength.

[0042] The following is a detailed description of the slitting process of rolled steel strip 5:

[0043] In the initial state, the steel strip 5 passes between the upper and lower eccentric self-locking bottom round cutters 3001 and 3001. The telescopic ends of the third drive components 206 in all clamping plate assemblies are in an extended state, so that all rollers 4001 are disengaged from the adjacent eccentric self-locking bottom round cutters 3001, without affecting the normal operation of the eccentric self-locking bottom round cutters 3001. The eccentric self-locking bottom round cutters 3001 are in a locked state, and the eccentric groove in the eccentric self-locking bottom round cutter 3001 presses against the round key 3002, so that the round key 3002 is locked in the keyway 3004, preventing the eccentric self-locking bottom round cutter 3001 from being displaced in the axial and circumferential directions along the cutter shaft 3.

[0044] Then the slitting process of steel strip 5 begins. The external power unit drives the cutter shaft 3 to rotate. Using a left-to-right view as a reference, the upper cutter shaft 3 and the eccentric self-locking bottom circular cutter 3001 rotate counterclockwise, while the lower cutter shaft 3 and the eccentric self-locking bottom circular cutter 3001 rotate clockwise. The two corresponding eccentric self-locking bottom circular cutters 3001 are staggered relative to each other. Figure 2 Taking the corresponding positions of the upper and lower eccentric self-locking bottom circular cutter 3001 as an example, the left edge of the upper eccentric self-locking bottom circular cutter 3001 and the right edge of the lower eccentric self-locking bottom circular cutter 3001 jointly apply shearing force to the steel strip 5, thereby separating the steel strip 5 into six smaller steel strips 5. However, if the eccentric self-locking bottom circular cutter 3001 cuts the steel strip 5 with one edge for a long time, the wear on the left and right edges of the eccentric self-locking bottom circular cutter 3001 will be inconsistent, resulting in the circumferential ring surface of the eccentric self-locking bottom circular cutter 3001 not being able to fit tightly with the surface of the steel strip 5, causing burrs to be generated at the shearing edge and reducing the quality of cutting the steel strip 5.

[0045] Therefore, after the eccentric self-locking bottom circular cutter 3001 has been cutting the steel strip 5 for a period of time (automatically timed by the device's control system), the cutter shaft 3 is first controlled to stop rotating. Simultaneously, the electric push rod on the support frame 2 is controlled to move the adjusting plate 2001 away from the steel strip 5, causing the upper and lower eccentric self-locking bottom circular cutters 3001 to disengage from the steel strip 5. At this time, the eccentric self-locking bottom circular cutter 3001 is still within the clamping range of the two rollers 4001 in the adjacent clamping plate group. Then, the motor 204 is controlled to drive the rotating frame 203 and its connecting parts to rotate, causing the clamping plate 4 to rotate closer to the eccentric self-locking bottom circular cutter 3001, thus bringing the blocking block 4003 closer to the center of the eccentric self-locking bottom circular cutter 3001. Then, the telescopic end of the third driving component 206 is controlled to retract, causing the two rollers 4001 to engage with the adjacent eccentric self-locking bottom circular cutter 3001. 1. Fitting: Taking the upper cutter shaft 3 as an example, first, control the upper cutter shaft 3 to drive the eccentric self-locking bottom circular cutter 3001, circular key 3002, and limiting block 3003 to continue rotating counterclockwise. This causes the limiting block 3003 to rotate counterclockwise until it contacts the blocking block 4003. At this point, the upper cutter shaft 3 continues to rotate, and the limiting block 3003 is blocked by the blocking block 4003 and cannot move, thus preventing the eccentric self-locking bottom circular cutter 3001 from continuing to rotate. Therefore, the eccentric self-locking bottom circular cutter 3001 rotates clockwise relative to the cutter shaft 3, and the eccentric groove rotates relative to the keyway 3004. This releases the pressure of the eccentric groove on the circular key 3002, allowing the circular key 3002 to slide within the keyway 3004, facilitating the movement of the eccentric self-locking bottom circular cutter 3001 in the left-right direction of the cutter shaft 3. The unlocked state of the eccentric self-locking bottom circular cutter 3001 is as follows: Figure 10 As shown, the second driving component 205 is then controlled to move the upper clamping plate assembly and the eccentric self-locking bottom circular cutter 3001 to the left, so that the right edge of the upper eccentric self-locking bottom circular cutter 3001 aligns with the cutting edge of the steel strip 5. The lower clamping plate assembly and the eccentric self-locking bottom circular cutter 3001 are then controlled to move to the right, so that the left edge of the lower eccentric self-locking bottom circular cutter 3001 aligns with the cutting edge of the steel strip 5. Then, the cutter shaft 3 is controlled to rotate clockwise, thereby causing the limiting block 3003 to rotate clockwise until it contacts the blocking block 4003 again. This causes the eccentric self-locking bottom circular cutter 3001 to rotate counterclockwise relative to the cutter shaft 3, causing the eccentric groove to press against the key 3002, thus locking the key 3002 onto the keyway 3004. This fixes the eccentric self-locking bottom circular cutter 3001 onto the cutter shaft 3. The locked state of the eccentric self-locking bottom circular cutter 3001 is as follows: Figure 11As shown, the adjustment of the position of the eccentric self-locking bottom circular cutter 3001 on the upper cutter shaft 3 is now complete. Similarly, the position of the eccentric self-locking bottom circular cutter 3001 on the lower cutter shaft 3 can be adjusted according to the above steps. After the upper and lower eccentric self-locking bottom circular cutters 3001 are adjusted, the control adjustment plate 2001 is moved closer to the steel strip 5 so that the eccentric self-locking bottom circular cutter 3001 is re-fitted with the steel strip 5. Then, the cutter shaft 3 is controlled to continue rotating. In this way, by exchanging the positions of the two corresponding eccentric self-locking bottom circular cutters 3001, the edges of the eccentric self-locking bottom circular cutters 3001 alternately cut the steel strip 5, thereby ensuring uniform circumferential wear of the eccentric self-locking bottom circular cutter 3001, improving the quality of the eccentric self-locking bottom circular cutter 3001 cutting the steel strip 5, extending the service life of the eccentric self-locking bottom circular cutter 3001, and reducing the maintenance cost of the eccentric self-locking bottom circular cutter 3001.

[0046] Based on this, considering that after the steel strip 5 is cut by the eccentric self-locking bottom circular cutter 3001, due to the shearing force applied to the cutting edge of the eccentric self-locking bottom circular cutter 3001, the cutting edge of the steel strip 5 may be bent and deformed, which is not conducive to the subsequent winding of the steel strip 5, therefore, during the cutting process of the steel strip 5, the first driving member 201 is controlled to drive the connecting frame 202 and its connecting parts to move away from the cutter shaft 3, so that the roller 4001 disengages from the adjacent eccentric self-locking bottom circular cutter 3001. Then, the third driving member 206 is controlled to drive the corresponding clamping plate 4 to move left and right, so that the upper and lower rollers 4 001 is aligned with the cutting edge of the adjacent steel strip 5. At this time, the connecting rod 301 and the sponge sleeve 302 both pass through the adjacent rollers 4001, and the isolation plate 4002 is directly opposite the gap between the two adjacent steel strips 5. Then, with left-to-right view as the reference, the motor 204 drives the upper front rotating frame 203 and rollers 4001 to rotate clockwise until the upper rollers 4001 press against the upper surface of the steel strip 5. The motor 204 then drives the lower front rotating frame 203 and rollers 4001 to rotate clockwise until the lower rollers 4001 press against the lower surface of the steel strip 5. The state is as follows. Figure 7As shown, the isolation plate 4002 is located between two adjacent steel strips 5. After the steel strip 5 is cut, it passes between the upper and lower rollers 4001. The rollers 4001 rotate synchronously. In this way, the upper and lower corresponding rollers 4001 flatten the cut edge of the steel strip 5, correct the raised part of the edge of the steel strip 5, and ensure the subsequent winding quality of the steel strip 5. In addition, the isolation plate 4002 isolates the two adjacent steel strips 5 to prevent the edge position of the two adjacent steel strips 5 from overlapping due to shaking, which would affect the effect of the rollers 4001 in correcting the edge of the steel strip 5. At the same time, the isolation plate 4002 is made of high-speed steel with good wear resistance and high hardness, which can ensure that the isolation plate 4002 will not deform after long-term contact with the steel strip 5. At this time, the roller 4001 located on the rear side is still in the initial state, disengaged from the adjacent eccentric self-locking bottom round knife 3001 so that the eccentric self-locking bottom round knife 3001 can rotate normally.

[0047] By nesting the groove 30101 on the connecting rod 301 with the protrusion on the adjacent roller 4001, the two rollers 4001 on the same clamping plate assembly can be ensured to rotate synchronously, thus improving the stability of the rollers 4001 during rotation. In addition, lubricating oil is usually applied to the eccentric self-locking bottom circular cutter 3001 before cutting, so that an oil film is formed on the surface of the eccentric self-locking bottom circular cutter 3001, thereby reducing the friction and wear of the eccentric self-locking bottom circular cutter 3001 when cutting the steel strip 5. However, as the eccentric self-locking bottom circular cutter 3001 continues to cut the steel strip 5, the oil film on the surface of the eccentric self-locking bottom circular cutter 3001 will gradually disappear, its lubrication effect will decrease, and the eccentric self-locking bottom circular cutter 3001 will become less effective. The wear of the circular cutter 3001 intensifies, reducing the flatness of the cut steel strip 5. Therefore, before the positions of the two eccentric self-locking bottom circular cutters 3001 are interchanged, the two rollers 4001 are in contact with the adjacent eccentric self-locking bottom circular cutter 3001, but the rollers 4001 have not yet applied lateral pressure to the eccentric self-locking bottom circular cutter 3001, and the connecting rod 301 is in contact with the adjacent eccentric self-locking bottom circular cutter 3001. Then, the external oil supply device is controlled to supply lubricating oil to the connecting pipe 304, so that the lubricating oil enters the inner cavity of the connecting rod 301 through the rotary joint 303 and seeps out from the liquid outlet 30102 into the sponge sleeve 302, allowing the sponge sleeve 302 to absorb the lubricant. At this point, the eccentric self-locking bottom circular cutter 3001 can be controlled to rotate, causing relative rotation between the eccentric self-locking bottom circular cutter 3001, the sponge sleeve 302, and the connecting rod 301. This allows the lubricating oil on the sponge sleeve 302 to be applied to the surface of the eccentric self-locking bottom circular cutter 3001, replenishing the oil film lost on the surface of the eccentric self-locking bottom circular cutter 3001, reducing cutting wear, and improving cutting quality. Note that by adjusting the rotation angle of the clamping plate 4 via the motor 204, it can be ensured that the limiting block 3003 of the eccentric self-locking bottom circular cutter 3001 will not contact the adjacent blocking block 4003 when rotating. Simultaneously, the roller 4... The surface of 001 is covered with an oil-absorbing layer to absorb the lubricating oil overflowing from the corners of the eccentric self-locking bottom circular knife 3001, and lubricating oil is applied to the left and right edges of the eccentric self-locking bottom circular knife 3001 to ensure that the connection between the eccentric self-locking bottom circular knife 3001 and the steel belt 5 is covered with lubricating oil. It should be noted that the rotary joint 303 can ensure that the sponge sleeve 302 can maintain communication with the connecting pipe 304 in real time when rotating. Furthermore, when the roller 4001 moves left and right, the corrugated hose of the connecting pipe 304 can ensure that the connecting pipe 304 can move synchronously with the roller 4001 and its connecting parts to meet the needs of conveying lubricating oil.

[0048] Based on this, after the eccentric self-locking bottom circular cutter 3001 completes cutting, it usually needs to be removed from the cutter shaft 3 and placed in a special storage area by the operator. During this process, the oil film covering the surface of the eccentric self-locking bottom circular cutter 3001 is easily wiped off by the operator's hands, which means that the oil film cannot completely protect the cutting edge of the eccentric self-locking bottom circular cutter 3001. As a result, the eccentric self-locking bottom circular cutter 3001 exposed to the air will rust, reducing the service life of the eccentric self-locking bottom circular cutter 3001. At the same time, the sharp cutting edge of the eccentric self-locking bottom circular cutter 3001 can easily cut the operator's hands, affecting the operator's safety.

[0049] To avoid the aforementioned problems, after the eccentric self-locking bottom circular cutter 3001 completes cutting, it can be unlocked according to the above steps to allow it to move left and right. The left support frame 2 is then continuously moved to the left via the electric slide rail, disengaging it from the cutter shaft 3. Here, we will describe the process in detail using the upper eccentric self-locking bottom circular cutter 3001 and its corresponding clamping plate 4 as an example. The third drive unit 206 is controlled to move the front clamping plate 4 left and right, aligning the two clamping plates 4 on the same clamping plate group with the left and right sides of the adjacent eccentric self-locking bottom circular cutter 3001. Then, the motor 204 is controlled to rotate the two upper rotating frames 203, causing the corresponding connecting rod 301 to engage with the adjacent eccentric self-locking bottom circular cutter 3001. Note that... Figure 9As shown, at this time, the connecting rod 301 is in contact with the lower half of the eccentric self-locking bottom circular knife 3001. Taking the view from left to right as a reference, the clamping plates 4 corresponding to the same eccentric self-locking bottom circular knife 3001 are arranged in a V-shape symmetrically in the front-back direction. Therefore, when the rotating frame 203 rotates, it is necessary to first drive the rotating frame 203 away from the eccentric self-locking bottom circular knife 3001 through the first driving member 201. When the connecting rod 301 rotates to a position lower than the center of the eccentric self-locking bottom circular knife 3001, the first driving member 201 then drives the rotating frame 203 closer to the eccentric self-locking bottom circular knife 3001. The self-locking bottom circular cutter 3001 ensures that the connecting rod 301 can rotate smoothly to contact the lower half of the eccentric self-locking bottom circular cutter 3001. Then, the third driving member 206 is controlled to make the roller 4001 clamp the corresponding eccentric self-locking bottom circular cutter 3001. Then, the second driving member 205 is controlled to drive the corresponding roller 4001 and the eccentric self-locking bottom circular cutter 3001 to move to the left, so that the eccentric self-locking bottom circular cutter 3001 slides to the left on the cutter shaft 3 until the cutter shaft 3 separates from the eccentric self-locking bottom circular cutter 3001. At this time, the eccentric self-locking bottom circular cutter 300... The two connecting rods 301 on the lower half support the eccentric self-locking bottom circular cutter 3001. At this time, the operator can hold the edge of the hollow part of the eccentric self-locking bottom circular cutter 3001 by hand to remove it from the connecting rods 301 and transfer it to the storage area. Compared with the conventional method of handling the eccentric self-locking bottom circular cutter 3001, this avoids the operator touching the sharp cutting edge of the eccentric self-locking bottom circular cutter 3001 with their hands, thus preventing damage to the oil film on its surface and improving the preservation of the eccentric self-locking bottom circular cutter 3001. This design provides protection and prevents the eccentric self-locking bottom circular knife 3001 from cutting the workers' hands, thus improving the safety of workers handling the eccentric self-locking bottom circular knife 3001. It should be noted that the sponge sleeve 302 is made of polyurethane foam material with good support performance and high hardness, thereby ensuring that the sponge sleeve 302 will not deform when the linkage rod 301 supports the eccentric self-locking bottom circular knife 3001, thereby improving the service life of the sponge sleeve 302. Similarly, the eccentric self-locking bottom circular knife 3001 located on the lower side is also disassembled and stored in accordance with the above steps.

[0050] In summary, by using the roller 4001 for clamping, the position of the eccentric self-locking bottom circular cutter 3001 can be adjusted during the cutting process, allowing the cutting edges of the eccentric self-locking bottom circular cutter 3001 to alternately cut the steel strip 5. This ensures uniform circumferential wear of the eccentric self-locking bottom circular cutter 3001, improving the quality of the steel strip 5 cut. Furthermore, while adjusting the position, lubricating oil is applied to the eccentric self-locking bottom circular cutter 3001 via the connecting rod 301, reducing wear caused by cutting and extending its service life. The rollers 4001 and the isolation plate 4002 work together to correct the raised edges of the steel strip 5, ensuring the quality of subsequent winding of the steel strip 5. Finally, the rollers 4001 and the linkage rod 301 work together to support the eccentric self-locking bottom circular knife 3001, preventing workers from directly contacting the cutting edge of the eccentric self-locking bottom circular knife 3001 and avoiding damage to the oil film on its surface, thus improving the protection effect of the eccentric self-locking bottom circular knife 3001. At the same time, it can prevent the eccentric self-locking bottom circular knife 3001 from cutting the workers' hands, improving the safety of workers handling the eccentric self-locking bottom circular knife 3001.

[0051] Example 2: Based on Example 1, as follows Figures 1-3 As shown, it also includes a nozzle 305; a nozzle 305 is fixedly connected to the second drive member 205 located on the rear side; each nozzle 305 is connected to an external air pump through a pipe; each nozzle 305 is aligned with the adjacent eccentric self-locking bottom circular knife 3001.

[0052] Considering that the eccentric self-locking bottom circular cutter 3001 will continuously generate heat on its surface when cutting steel strip 5, in order to avoid the wear resistance of the eccentric self-locking bottom circular cutter 3001 decreasing due to the temperature rise, an external air pump can be controlled to supply air into the nozzle 305, so that the airflow blows through the nozzle 305 to the adjacent eccentric self-locking bottom circular cutter 3001, thereby achieving the cooling of the eccentric self-locking bottom circular cutter 3001.

[0053] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of the invention. Therefore, the scope of the invention should be limited only by the appended claims.
