Description

Technical Field

[0001] The invention relates to a flattening and cutting device, in particular to a flattening and cutting device for hot-rolled coils applied in the technical field of metal processing. Background Art

[0002] Hot rolled coil refers to a thin sheet metal product made by pressing and deforming metal billets through a rolling mill at high temperature. Due to its excellent mechanical properties, processing performance and stability, it is widely used in automobile manufacturing, aerospace, shipbuilding, construction, machinery, pressure vessels and other fields.

[0003] In the application of hot-rolled coils, it is often necessary to cut the coiled hot-rolled coils into straight steel plates of a certain length. When cutting, the hot-rolled coils need to be unrolled and leveled by a leveling machine first, and the leveled plates are transported to a shearing machine, and then the leveled plates are cut into steel plates of the target length by the shearing machine, and finally the cut steel plates are transported away by a conveying mechanism.

[0004] The travel length of the coil is one of the main factors affecting the cutting accuracy. Between two cuts, the travel length of the plate should be strictly equal to the preset cutting length. However, in actual operation, the travel length of the plate is prone to deviation due to conveying speed fluctuations, transmission component wear, instrument failure, etc. This deviation will cause the length of the cut steel plate to be inconsistent with the preset length, which will lead to material waste, unqualified products and other adverse consequences. Therefore, we propose a flat cutting device for hot-rolled coils. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is: when cutting hot-rolled coils, how to avoid the deviation of the travel length of the plate resulting in the length of the cut steel plate being inconsistent with the preset length.

[0006] In order to solve the above problems, the present invention provides a hot-rolled coil flat cutting device, comprising a flattening machine provided with a flattening control center, a shearing machine provided with a cutting control center, a conveying mechanism provided with a conveying control center, and a traveling inspection mechanism, the traveling inspection mechanism comprising a verification support box, the verification support box is provided with an interval test run assembly, the interval test run assembly comprises an interval test run rod penetratingly arranged on the outer wall of the verification support box, the interval test run rod is slidably connected to the outer wall of the verification support box, both sides of the interval test run rod are fixedly connected with a driving elastic rope, the other end of the driving elastic rope is fixedly connected to the inner wall of the verification support box and the driving elastic rope is in a stretched state, the interval test run rod is sleeved with a positioning ring fixedly connected to the same, the positioning ring is against the inner wall of the verification support box under the action of the driving elastic rope, the interval test run assembly also comprises a distance sensor fixedly installed in the verification support box, and the interval test run rod is located directly in front of the distance sensor;

[0007] The travel verification mechanism also includes a verification and alarm intelligent controller, which is provided with a data input module and a verification and alarm module. The data input module and the distance sensor are both connected to the verification and alarm module signal. An alarm is fixedly installed on the top of the verification and alarm intelligent controller, and the verification and alarm module is connected to the alarm signal.

[0008] In the above-mentioned hot-rolled coil flat cutting device, the travel verification mechanism can verify the travel length of the plate before cutting. The plate will be cut only after the verification is passed, thereby ensuring that the cut steel plate strictly meets the requirements.

[0009] As a further improvement of the present application, the Kaiping control center is signal-connected to the verification intelligent warning module, the verification intelligent warning module is signal-connected to the cutting control center, the cutting control center is signal-connected to the Kaiping control center and the conveying control center, the shearing machine is located between the Kaiping machine and the conveying mechanism, the travel verification mechanism is located on the side of the conveying mechanism away from the shearing machine, the in-progress test rod is arranged on the outer wall of the verification support box close to the conveying mechanism, and the distance sensor is arranged on the inner wall of the verification support box away from the conveying mechanism.

[0010] As a further improvement of the present application, the method of using the traveling verification mechanism is as follows: the cutting length and tolerance are set according to the requirements, and the distance between the verification support box and the shearing machine is adjusted according to the cutting length. The cutting length is set to L1, and the horizontal distance between the intermediate test rod and the cutting tool on the shearing machine after adjustment is set to L2. The distance between the intermediate test rod and the distance sensor in the initial state is set to L3. After the adjustment is completed, L2 needs to be less than L1, and L3 needs to be greater than (L1-L2). L1, L2, L3 and the tolerance are input into the verification intelligent warning module through the data input module, and the leveling machine moves to the shearing machine according to the cutting length. After the shearing machine conveys the corresponding length of the plate, the actual distance between the test rod and the distance sensor at this time is set to be L4. If the difference between (L3-L4) and (L1-L2) is not greater than the tolerance, it means that there is no deviation in the travel length of the plate. The verification intelligent alarm module will send a signal to the cutting control center to enable the cutting control center to control the shearing machine to cut the plate. If the difference between (L3-L4) and (L1-L2) is greater than the tolerance, it means that there is a deviation in the travel length of the plate. The shearing machine will not cut the plate, and the verification intelligent alarm module will activate the alarm, causing the alarm to sound.

[0011] As a further improvement of the present application, the traveling verification mechanism also includes a support adjustment mechanism, which includes an adjustment support box and a plurality of support frames for supporting the adjustment support box.

[0012] As a further improvement of the present application, the lifting cylinder is located above the verification support box and the output end of the lifting cylinder is fixedly connected to the verification support box. A lifting adjustment module is also provided in the verification alarm intelligent controller. The lifting adjustment module is connected to the lifting cylinder signal. The support adjustment mechanism can not only support the verification support box, but also drive the verification support box to move and adjust.

[0013] As a further improvement of the present application, there are two interval test components, and the two interval test components are symmetrically arranged. A tilt detection intelligent alarm module is also provided in the alarm verification intelligent controller. The distance sensor is signal-connected with the tilt detection intelligent alarm module, and the tilt detection intelligent alarm module is signal-connected with the alarm, the verification intelligent alarm module, and the Kaiping control center, so that the traveling verification mechanism also has the function of detecting whether the plate is tilted.

[0014] As another improvement of the present application, a self-inspection protection component is provided on one side of each interval test running component, and the self-inspection protection component includes a support tube and a distance rod fixedly installed in the calibration support box, a repulsion electromagnet is fixedly installed in the support tube, a push-inspection slide bar is penetrated through the outer wall of the support tube near one end of the distance rod, the push-inspection slide bar is slidably connected to the outer wall of the support tube, and a repulsion magnet is fixedly connected to the end of the push-inspection slide bar near the repulsion electromagnet, the support tube and the interval test running rod are located on the same side, the distance rod and the distance sensor are located on the same side, and both sides of the push-inspection slide bar are fixedly connected with a tensioning elastic rope, and the other end of the tensioning elastic rope is fixedly connected to the inner wall of the support tube.

[0015] As another improvement supplement to the present application, the self-inspection guarantee component also includes a push rod plate, which is fixedly connected to the interval test rod, and the end of the push-inspection slide rod away from the repulsion electromagnet is against the push rod plate. A self-inspection control module is also provided in the alarm intelligent controller, and a self-inspection button and a feedback light are provided on the alarm intelligent controller. The distance sensor, data input module, and self-inspection button are all connected to the self-inspection control module signal, and the self-inspection control module is connected to the feedback light signal. The distance between the push rod plate and the distance rod is smaller than the distance between the distance sensor and the interval test rod, so that the travel verification mechanism also has a self-inspection function.

[0016] As another improved supplement of the present application, the support tube is made of magnetic isolation material to prevent the repelling electromagnet from affecting the distance sensor.

[0017] In summary, the present application sets up a travel verification mechanism, so that the travel verification mechanism can verify the travel length of the plate before cutting, and the plate will be cut only after the verification is passed, thereby ensuring that the cut steel plate strictly meets the requirements, thereby improving the cutting accuracy, and effectively avoiding adverse consequences such as material waste and unqualified products due to deviations in the travel length of the plate; through the setting of the support adjustment mechanism, the support adjustment mechanism can not only support the verification support box, but also drive the verification support box to move and adjust, in addition, the support adjustment mechanism can also drive the verification support box to lift and lower, so that the conveying mechanism can smoothly transport the steel plate, thereby improving the practicality of the travel verification mechanism; through the connection of two intermediate test travel components and the inclination detection intelligent warning module, etc. The combined arrangement enables the traveling verification mechanism to also have the function of detecting whether the plate is tilted, and when the plate is tilted during travel, it will not only prevent the shearing machine from cutting the plate, but also remind the relevant technical personnel through the alarm, thereby avoiding the adverse consequences of material waste, product failure, etc. caused by cutting the plate when the plate is tilted, greatly improving the functionality of the traveling verification mechanism and further improving the cutting accuracy; through the arrangement of the self-checking guarantee component, the traveling verification mechanism also has a self-checking function, which can automatically detect and verify whether there is a fault in the distance sensor, avoiding the influence of the verification function of the traveling verification mechanism due to the fault of the distance sensor, thereby ensuring the accuracy of the verification function of the traveling verification mechanism, and greatly improving the reliability of the traveling verification mechanism.

[0028] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0029] The first implementation method:

[0030] Figure 1-5A hot rolled coil flat cutting device is shown, comprising a flattening machine provided with a flattening control center, a shearing machine provided with a cutting control center, a conveying mechanism provided with a conveying control center, and a traveling inspection mechanism. The flattening machine is used to unroll, flatten, and convey the hot rolled coil, the shearing machine is used to cut the flattened plate, and the conveying mechanism is used to convey the cut steel plate. The flattening machine, the shearing machine, and the conveying mechanism are all prior art, and their specific structures are not described in detail here. The traveling inspection mechanism includes a verification support box 101, and the verification support box The test run assembly is provided on the test support box 101, and the test run assembly includes a test run rod 201 which is arranged on the outer wall of the test support box 101, and the test run rod 201 is slidably connected to the outer wall of the test support box 101, and both sides of the test run rod 201 are fixedly connected with a driving elastic rope 202, and the other end of the driving elastic rope 202 is fixedly connected to the inner wall of the test support box 101 and the driving elastic rope 202 is in a stretched state, and the test run rod 201 is provided with a positioning ring 203 fixedly connected thereto, and the positioning ring 203 is in a driving state. The elastic rope 202 is pressed against the inner wall of the verification support box 101. The test run assembly also includes a distance sensor 204 fixedly installed in the verification support box 101. The test run stick 201 is located directly in front of the distance sensor 204. The travel verification mechanism also includes a verification alarm intelligent controller 003. The verification alarm intelligent controller 003 is provided with a data input module and a verification intelligent alarm module. The data input module and the distance sensor 204 are all connected to the verification intelligent alarm module signal. An alarm 301 is fixedly installed on the top of the verification alarm intelligent controller 003. The intelligent warning module is connected to the alarm 301 by signal, the Kaiping control center is connected to the verification intelligent warning module by signal, the verification intelligent warning module is connected to the cutting control center by signal, the cutting control center is connected to the Kaiping control center and the conveying control center by signal, the shearing machine is located between the Kaiping machine and the conveying mechanism, the traveling verification mechanism is located on the side of the conveying mechanism away from the shearing machine, the in-progress test rod 201 is arranged on the outer wall of the verification support box 101 close to the conveying mechanism, and the distance sensor 204 is arranged on the inner wall of the verification support box 101 away from the conveying mechanism.

[0031] Set the cutting length (i.e. the required length of the steel plate) and the tolerance (a certain error is usually allowed for cutting), adjust the distance between the calibration support box 101 and the shearing machine according to the cutting length, set the cutting length as L1, the horizontal distance between the intermediate test rod 201 and the cutting tool on the shearing machine after adjustment as L2, and the distance between the intermediate test rod 201 and the distance sensor 204 in the initial state as L3. After the adjustment is completed, L2 must be less than L1, and L3 must be greater than (L1-L2). Input L1, L2, L3 and the tolerance to the calibration intelligent warning module through the data input module. When cutting the hot-rolled coil, hoist the hot-rolled coil onto the leveling machine, start the leveling machine to unroll and level the hot-rolled coil, and make the leveling machine The uncoiling and leveling processed plates are fed to the shearing machine, so that the plates pass under the cutting tool on the shearing machine. In the prior art, after the uncoiling machine feeds the plates of corresponding length to the shearing machine according to the cutting length, the uncoiling machine will temporarily stop the uncoiling, leveling and conveying work, and the uncoiling control center will directly send a signal to the cutting control center, so that the cutting control center controls the shearing machine to cut the plates, and then the cut steel plates are transported away by the conveying mechanism (usually transported to the stacker, so that the stacker stacks the steel plates), and then the uncoiling control center will control the uncoiling machine to continue to uncoil, level and convey the hot-rolled coils. However, in the present application, when the uncoiling machine feeds the plates to the shearing machine, the plates move to abut against the spacing test rod 201, which will push the spacing test rod 201. The distance sensor 204 can monitor the distance between the distance sensor 204 and the test rod 201, and the distance data monitored by the distance sensor 204 will be transmitted to the verification intelligent warning module in real time. When the unwinding, leveling and conveying work of the Kaiping machine is temporarily stopped, the Kaiping control center will send a signal to the verification intelligent warning module, causing the verification intelligent warning module to verify the travel length of the plate. Suppose the actual distance between the test rod 201 and the distance sensor 204 at this time is L4 (L4 can be measured by the distance sensor 204). After receiving the signal, the verification intelligent warning module will analyze and calculate according to L1, L2, L3 and L4. If the difference between (L3-L4) and (L1-L2) If the difference between (L3-L4) and (L1-L2) is greater than the tolerance, it means that there is no deviation in the travel length of the plate. At this time, the verification intelligent alarm module will send a signal to the cutting control center to control the shearing machine to cut the plate. After the cutting is completed, the cutting control center will send a signal to the Kaiping control center to control the Kaiping machine to continue to unwind, level and convey the plate. At the same time, the cutting control center will also send a signal to the conveying control center to control the conveying mechanism to transport the cut steel plate. On the contrary, if the difference between (L3-L4) and (L1-L2) is greater than the tolerance, it means that there is a deviation in the travel length of the plate. At this time, the verification intelligent alarm module will activate the alarm 301 to make the alarm 301 sound to remind the relevant technical personnel.It prompts relevant technical personnel to come and carry out corresponding processing. Therefore, through the setting of the travel verification mechanism, the travel verification mechanism can verify the travel length of the plate before cutting. The plate will be cut only after the verification is passed, so as to ensure that the cut steel plate strictly meets the requirements, thereby improving the cutting accuracy, and effectively avoiding the adverse consequences such as material waste and unqualified products due to the deviation of the travel length of the plate. In addition, when the travel verification mechanism verifies the travel length of the plate, it does not directly measure the movement of the plate, but indirectly measures the movement of the plate by measuring the movement of the test rod 201, thereby achieving the purpose of verifying the travel length of the plate. Because the plate is usually thin, if the movement of the plate is directly measured, errors are prone to occur. Therefore, the travel verification mechanism has high accuracy and reliability.

[0032] See also Figure 1-2 and Figure 4The travel verification mechanism also includes a support adjustment mechanism, which includes an adjustment support box 401 and a plurality of support frames 402 for supporting the adjustment support box 401. A translation cylinder 403 is fixedly installed in the adjustment support box 401, and a linkage plate 404 is fixedly connected to the output end of the translation cylinder 403. A linkage slide groove 405 matching the linkage plate 404 is provided on the outer wall of the bottom end of the adjustment support box 401. The linkage plate 404 penetrates the linkage slide groove 405 and is slidably connected thereto. The bottom end of the linkage plate 404 is fixed The lifting cylinder 406 is fixedly connected, and the lifting cylinder 406 is located above the verification support box 101. The output end of the lifting cylinder 406 is fixedly connected to the verification support box 101. The verification alarm intelligent controller 003 is also provided with a lifting adjustment module, and the lifting adjustment module is connected to the lifting cylinder 406 signal. When adjusting the distance between the verification support box 101 and the shearing machine, the verification support box 101 can be driven to move horizontally by controlling the translation cylinder 403, so that the verification support box 101 is easy to move and adjust, and the plate When the travel length of the plate is checked, if there is no deviation in the travel length of the plate, the verification intelligent warning module sends a signal to the cutting control center and also sends a signal to the lifting and adjusting module. After receiving the signal, the lifting and adjusting module will control the lifting cylinder 406 to drive the verification support box 101 to move upward, causing the intermediate test rod 201 to separate from the plate, until the bottom end of the verification support box 101 is higher than the top end of the plate, so that the conveying mechanism can smoothly transport the cut steel plate, and the speed at which the conveying mechanism conveys the steel plate is greater than the speed at which the leveling machine conveys the plate. After the conveying mechanism transports the steel plate away, the lifting and adjusting module will control the lifting cylinder 406 to drive the verification support box 101 to move downward and reset. Therefore, through the setting of the support adjustment mechanism, the support adjustment mechanism can not only support the verification support box 101, but also drive the verification support box 101 to move and adjust. In addition, the support adjustment mechanism can also drive the verification support box 101 to lift and adjust, so that the conveying mechanism can smoothly transport the steel plate, thereby improving the practicality of the travel verification mechanism. In addition, when the plate pushes the test rod 201, the driving elastic rope 202 will be further stretched. After the test rod 201 is separated from the plate, the driving elastic rope 202 will rebound to a certain extent. In addition, since the driving elastic rope 202 is also in a stretched state in the initial state (when the plate is not pushed by the plate), combined with the positioning function of the positioning ring 203, after the test rod 201 is separated from the plate, the distance between the test rod 201 and the distance sensor 204 can automatically return to the initial state, thereby ensuring the accuracy and reliability of the travel verification mechanism.

[0033] See also Figure 3-4There are two interval test components, and the two interval test components are symmetrically arranged. The inspection and alarm intelligent controller 003 is also provided with an inclination detection intelligent alarm module. The distance sensor 204 is connected to the inclination detection intelligent alarm module by signal. The inclination detection intelligent alarm module is connected to the alarm 301, the verification intelligent alarm module, and the Kaiping control center by signal. The distance data monitored by the distance sensor 204 will also be transmitted to the inclination detection intelligent alarm module in real time. When the Kaiping machine conveys the plate to the shearing machine, after the plate moves to the traveling verification mechanism, it will simultaneously push the two interval test rods 201 in the two interval test components. Under normal circumstances In this case, the movement of the two test rods 201 should be synchronized, and the distance data monitored by the two distance sensors 204 should also be consistent. The tilt detection intelligent warning module will analyze and compare the distance data monitored by the two distance sensors 204. If the plate tilts during the movement, the edge of the plate in contact with the two test rods 201 will also be tilted, which will cause the movement of the two test rods 201 to be asynchronous, and further cause the distance data monitored by the two distance sensors 204 to be inconsistent, so that the tilt detection intelligent warning module can analyze and compare the distance data monitored by the two distance sensors 204. The distance data monitored by the two distance sensors 204 are used to determine whether the plate is tilted. When the tilt detection intelligent warning module finds that the distance data monitored by the two distance sensors 204 are inconsistent, the tilt detection intelligent warning module will start the alarm 301, so that the alarm 301 sends an alarm to remind the relevant technical personnel, prompting the relevant technical personnel to take corresponding measures in time. At the same time, the tilt detection intelligent warning module will also send signals to the Kaiping control center and the verification intelligent warning module, causing the Kaiping control center to control the Kaiping machine to stop conveying the plate, and prevent the verification intelligent warning module from sending signals to the cutting control center, thereby preventing the shearing machine from cutting the plate. Therefore, through the joint setting of the two intermediate test components and the tilt detection intelligent warning module, the travel verification mechanism also has the function of detecting whether the plate is tilted, and when the plate is tilted during travel, not only will the shearing machine be prevented from cutting the plate, but the alarm 301 will also be used to remind the relevant technical personnel, thereby avoiding the adverse consequences such as material waste and unqualified products caused by cutting the plate when the plate is tilted, greatly improving the functionality of the travel verification mechanism, and further improving the cutting accuracy. In addition, the alarm 301 can emit at least two different alarm sounds. When the verification intelligent alarm module and the tilt detection intelligent alarm module activate the alarm 301, the alarm 301 will emit different alarm sounds, making it easy for relevant technical personnel to distinguish them.

[0034] The second implementation method:

[0035] Figure 6-8A hot rolled coil cutting device is shown. Different from the first embodiment, a self-checking and guaranteeing component is arranged on one side of each test run component. The self-checking and guaranteeing component comprises a support tube 501 and a distance rod 506 fixedly installed in a calibration support box 101. A repelling electromagnet 502 is fixedly installed in the support tube 501. A push-checking slide bar 503 is penetrated through the outer wall of the support tube 501 near one end of the distance rod 506. The push-checking slide bar 503 is slidably connected to the outer wall of the support tube 501. A repelling magnet 504 is fixedly connected to one end of the push-checking slide bar 503 near the repelling electromagnet 502. The support tube 501 and the test run bar 201 are located on the same side. The distance rod 506 and the distance sensor 204 are located on the same side. Both sides of the push-checking slide bar 503 are fixedly connected with a tensioning elastic rope 50 7. The other end of the restoring elastic rope 507 is fixedly connected to the inner wall of the support tube 501. The self-inspection guarantee component also includes a push rod plate 505. The push rod plate 505 is fixedly connected to the interval test rod 201. The end of the push-inspection slide rod 503 away from the repelling electromagnet 502 is against the push rod plate 505. A self-inspection control module is also provided in the alarm intelligent controller 003. A self-inspection button and a feedback light are provided on the alarm intelligent controller 003. The distance sensor 204, the data input module and the self-inspection button are all connected with the self-inspection control module signal. The self-inspection control module is connected with the feedback light signal. The distance between the push rod plate 505 and the distance rod 506 is smaller than the distance between the distance sensor 204 and the interval test rod 201. The support tube 501 is made of magnetic isolation material to prevent the repelling electromagnet 502 from affecting the distance sensor 204.

[0036] Assume that the distance between the push rod plate 505 and the distance rod 506 in the initial state is L5, and L5 and L3 are input to the self-checking control module through the data input module. Before the hot rolled coil is flattened and cut, a self-checking instruction is issued to the self-checking control module through the self-checking button. After receiving the instruction, the self-checking control module will control the repulsion electromagnet 502 to be energized, so that the repulsion electromagnet 502 applies a magnetic repulsion force to the repulsion magnet 504. Under the action of the magnetic repulsion force, the push-checking slide bar 503 will push the push rod plate 505 to move in the direction close to the distance rod 506. The push rod plate 505 moves until it contacts the distance rod 506, and causes the elastic rope 507 to be stretched. At the same time, the movement of the push rod plate 505 drives the interval test rod 201 to move together, so that the interval test rod 201 moves a certain distance toward the direction close to the distance sensor 204, and the distance moved by the interval test rod 201 is equal to L5. The distance data monitored by the distance sensor 204 is also transmitted to the self-checking control module. If the distance data monitored by the distance sensor 204 is L6 at this time, the self-checking control module can According to L3, L5, and L6, if L6=L3-L5, it means that the distance sensor 204 functions normally. At this time, the self-check control module will light up the feedback light, so that the feedback light emits a green light, indicating that the self-check has passed. On the contrary, if L6≠L3-L5, it means that the distance sensor 204 may have a fault and its detection accuracy has problems. At this time, the self-check control module will light up the feedback light, so that the feedback light emits a red light, indicating that the self-check has not passed. After the self-check is completed, the self-check control module will control the repelling electromagnet 502 to turn off. The push-check slide bar 503 is automatically reset under the action of the pull-back elastic rope 507, and the interval test travel rod 201 is automatically reset under the action of the drive elastic rope 202. Therefore, through the setting of the self-checking guarantee component, the travel verification mechanism also has a self-checking function, which can automatically detect and verify whether the distance sensor 204 is faulty, and avoid affecting the verification function of the travel verification mechanism due to the fault of the distance sensor 204, thereby ensuring the accuracy of the verification function of the travel verification mechanism and greatly improving the reliability of the travel verification mechanism. In addition, it should be noted that when adjusting the distance between the verification support box 101 and the shearing machine according to the cutting length, it is necessary to ensure that L5 is greater than (L1-L2).

[0037] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
