Description

TECHNICAL FIELD

[0001] The application relates to the field of steel plate processing equipment, in particular to a high-quality steel plate slitting equipment and a use method. BACKGROUND

[0002] In the steel plate slitting production line, a steel plate roll is installed on a steel plate unwinding device, and the steel plate on the steel plate roll is unwound through the steel plate unwinding device. The unwound steel plate enters a flattening machine for flattening, and the flattened steel plate enters a cross-cutting machine for cross-cutting and forming a plurality of cross-cutting steel plates. The cross-cutting steel plates after cross-cutting are conveyed to a material receiving part through a conveying part to realize stacking and collection.

[0003] At present, in the stacking process, the newly cross-cut steel plate directly falls naturally onto the steel plate stack, and then the newly cross-cut steel plate is pushed by artificial or a first hydraulic cylinder to make the steel plate stack neatly stacked.

[0004] However, in the process of falling downward of the newly cross-cut steel plate, the steel plate will produce a certain angle of deflection, so as to fail to maintain a horizontal falling state, and will collide with the lower steel plate with a small contact area. On the one hand, it will cause the steel plate to bend and deform, and on the other hand, it will also produce scratches or depressions on the collided steel plate, which will irreversibly affect the appearance of the steel plate. Moreover, there may be oxidation scale, waste or dust and other sundries on the top of the steel plate stack. After the newly cross-cut steel plate covers on the top, the sundries will always remain between the two steel plates, which will also produce defects on the steel plate, thereby reducing the quality of the steel plate. SUMMARY

[0005] In order to improve the problem that the steel plates will collide hard with each other in the process of stacking the steel plates, causing the steel plates to bend and deform and reducing the quality of the steel plates, the application provides a high-quality steel plate slitting equipment and a use method.

[0006] In a first aspect, the application provides a high-quality steel plate slitting equipment,

[0007] The following technical scheme is adopted:

[0008] A high-quality steel plate slitting equipment, which comprises an unwinding mechanism, a flattening mechanism, a plate shearing mechanism and a stacking mechanism. After the steel roll is unwound, flattened and cross-cut, the steel plate is formed and stacked in the stacking mechanism. The stacking mechanism comprises a stacking table and a movable grabbing unit arranged on one side of the stacking table. The movable grabbing unit grabs and places the steel plate on the stacking table.

[0009] The movable grabbing unit comprises an inverted L-shaped support, a grabbing plate and a first hydraulic cylinder, the grabbing plate is connected with the support, the bottom of the grabbing plate is provided with a plurality of suction cups for sucking the steel plate, the first hydraulic cylinder is connected with the vertical end of the support and drives the support to move up and down, and the first hydraulic cylinder is arranged on the moving platform and slides on the moving platform.

[0010] By adopting the above technical scheme, after a steel plate is generated by once transverse cutting of the steel coil, the first hydraulic cylinder moves on the moving platform, and the support and the grabbing plate are moved above the steel plate, then the push rod of the first hydraulic cylinder is retracted inward, so that the grabbing plate moves downward and approaches the steel plate, when the suction cups below the grabbing plate are attached to the steel plate, the first hydraulic cylinder is elongated outward again, so that the grabbing plate and the steel plate are lifted to a higher position, the first hydraulic cylinder moves reversely on the moving platform, so that the steel plate is dragged to above the stacking table, then the first hydraulic cylinder is retracted inward and the suction cups are released, so that the steel plate approaches or is attached to the top of the stacking table, and the grabbing action of the movable grabbing unit on the steel plate is ended, so that the steel plate is in a horizontal state during movement and lowering, and cannot collide with the top of the stacking table or the steel plate placed on the stacking table, that is, the collision between the four corners or one side of the steel plate being lowered and the stacking table or the steel plate on the stacking table can be prevented, so that the steel plate cannot be deformed or defective during stacking, and the finished product quality of the steel plate is ensured to be high.

[0011] Optionally, the top of the moving platform is provided with a sliding groove extending along the sliding direction of the steel plate, a lead screw driven by a motor is arranged in the sliding groove, a sliding seat is fitted on the lead screw, and a connecting plate for connecting the first hydraulic cylinder and the sliding seat is arranged on the top of the moving platform.

[0012] By adopting the above technical scheme, the motor drives the lead screw to rotate, the sliding seat is arranged in the sliding groove, the connecting plate is arranged outside the sliding groove and connected with the sliding seat, so that the connecting plate forms a limiting action on the sliding seat, and the sliding seat is fitted with the lead screw, so that the horizontal displacement of the sliding seat can be realized by rotation of the lead screw, and the first hydraulic cylinder is arranged on the connecting plate, so that the driving action on the first hydraulic cylinder and the grabbing plate can be realized by movement of the sliding seat, and the movable grabbing unit can reliably grab and place the steel plate on the stacking table.

[0013] Optionally, one end of the sliding groove is close to the end of the shearing mechanism, and the other end is close to the end of the stacking mechanism; the sliding seat is connected with the lead screw through threads, the outer wall of the sliding seat is attached to the inner wall of the sliding groove, and the outer diameter of the connecting plate is greater than the width of the sliding groove.

[0014] By adopting the above technical scheme, the shapes and sizes of the connecting plate and the sliding seat are limited, so that the movable grabbing unit can be driven by rotation of the lead screw driven by the motor.

[0015] Optionally, one side of the material grabbing plate is hinged to the vertical end of the support, the other side of the material grabbing plate is provided with a movable seat, a cylinder is arranged on the horizontal end of the support, the cylinder is away from the vertical end of the support, and the push rod of the cylinder is connected with the movable seat.

[0016] By adopting the above technical scheme, the cylinder is connected with the movable seat on the material grabbing plate, so that the driving action of the cylinder on the movable seat can be converted into the rotation of the material grabbing plate, that is, the other side of the material grabbing plate is pushed by the cylinder to rotate around one side of the material grabbing plate, so as to realize the inclination of the material grabbing plate. After the first hydraulic cylinder is retracted inward, one side of the steel plate on the material grabbing plate will first contact the top of the stacking table. In this posture, the suction of the suction plate to the steel plate is released, and the steel plate will gradually tilt from one side. Since one side of the steel plate is closely attached to the top of the stacking table, the distance between any two points in any area parallel to one side of the steel plate and the top of the stacking table is the same during the rotation and pressing of the steel plate. Therefore, it can be ensured that the steel plate will not deviate during the rotation and pressing of the steel plate. Since the pressing speed of the steel plate is high, the air between the steel plate and the stacking table cannot be quickly discharged, so a lifting force is formed on the steel plate, ensuring that the rotation and pressing of the steel plate are more stable. Moreover, since the steel plate rotates and presses around one side of the steel plate, the air discharge has a certain directionality. Therefore, the air can more effectively carry out the debris between the steel plate and the stacking table during the discharge process, preventing small debris from causing indentations or scratches on the surface of the steel plate after the steel plate contacts the stacking table, and further ensuring the finished product quality of the steel plate.

[0017] Optionally, the height of one side of the material grabbing plate is not higher than the height of the other side of the material grabbing plate.

[0018] By adopting the above technical scheme, one side of the steel plate close to the first hydraulic cylinder will first contact the stacking table. After the steel plate rotates and presses and interacts with the air, the steel plate will deviate in a horizontal direction, and the deviation direction is away from the first hydraulic cylinder, thereby effectively preventing the steel plate from colliding with the first hydraulic cylinder and causing damage to the first hydraulic cylinder or deformation of the steel plate.

[0019] Optionally, one side of the outer wall of the stacking table faces the chute, and the remaining three sides of the outer wall of the stacking table are each provided with at least one accommodating groove, and the accommodating groove is provided with a second hydraulic cylinder, a spring and a positive L-shaped limiting plate.

[0020] The horizontal end of the limiting plate is inserted into the accommodating groove and connected with the spring, the vertical end of the limiting plate is located outside the accommodating groove and extends above the stacking table, and the second hydraulic cylinder drives the horizontal end of the limiting plate to move outward of the accommodating groove.

[0021] By adopting the technical scheme, after the steel plate is offset under rotation and pressing, the steel plate will hit the vertical end of the limiting plate, and the buffer effect is realized through the movement of the limiting plate as a whole and the stretching of the spring to store energy, and then the spring rebounds to realize the resetting of the offset steel plate and neatly stack the steel plate on the stacking table; further, in order to reduce the impact strength between the steel plate and the limiting plate, the horizontal end of the limiting plate can be pushed to the outside of the accommodating groove by the second hydraulic cylinder before the suction cup releases the steel plate, so that the vertical end of the limiting plate is away from the stacking table and the spring is in a pre-tensioning state, so that after the steel plate is offset under rotation and pressing, the steel plate can slide a distance without interference, and then stop or stop after contacting the limiting plate, effectively reducing the relative speed of the steel plate and the limiting plate when they contact each other, and after the steel plate slides a distance and then contacts the limiting plate, the limiting plate can still realize the buffer through its displacement and the stretching of the spring.

[0022] Optionally, the push rod of the second hydraulic cylinder and the horizontal end of the limiting plate are connected through a pull rope, and the pull rope is used to pull the horizontal end of the limiting plate.

[0023] By adopting the technical scheme, the push rod of the second hydraulic cylinder and the horizontal end of the limiting plate are not connected, so that after the second hydraulic cylinder pushes the limiting plate away from the stacking table and the steel plate slides and impacts the limiting plate, the limiting plate can continue to slide and will not pull the push rod of the second hydraulic cylinder, preventing the limiting plate from having too much acceleration after the steel plate and the limiting plate impact each other, causing damage to the second hydraulic cylinder; further, through the setting of the pull rope, on the one hand, the displacement of the limiting plate can be limited to prevent the limiting plate from being displaced too much and coming out of the accommodating groove or causing the spring to exceed the elastic limit and be damaged, and on the other hand, the push rod of the second hydraulic cylinder can be retracted inward to form a pulling action on the pull rope and the horizontal end of the limiting plate, preventing the spring from being unable to realize the complete resetting of the steel plate, that is, through the connecting action of the pull rope, the soft connection between the second hydraulic cylinder and the limiting plate can be realized, ensuring that the movement of the limiting plate out of the accommodating groove will not damage the second hydraulic cylinder, and the pulling action of the second hydraulic cylinder on the limiting plate is reliable.

[0024] Optionally, the top of the stacking table is further provided with a pair of grooves, and the steel plates on the stacking table are packaged or lifted through the grooves.

[0025] By adopting the technical scheme, after the stacking of the steel plates is completed, the steel plates can be packaged and limited by inserting a packaging material such as a steel belt or a steel cable into the lowermost steel plate through the grooves, and the steel plates on the stacking table can be transferred by a travelling crane or a forklift.

[0026] Optionally, a conveying mechanism for conveying the steel plates is further arranged between the plate shearing mechanism and the stacking mechanism, and the movable grabbing unit grabs the steel plates on the conveying mechanism to the stacking table.

[0027] By adopting the technical scheme, the steel plate formed after the cross-cutting can be conveyed on the conveying mechanism by the plate shearing mechanism, thereby reducing the stroke of the movable gripping unit, and the conveying mechanism can also serve as a storage function, so that the connection between the plate shearing mechanism and the stacking mechanism is more coherent.

[0028] In a second aspect, the application provides a use method of the fine steel plate slitting equipment, which adopts the technical scheme as follows.

[0029] A use method of a fine steel plate slitting equipment, comprising the following steps: S1, placing a steel coil into an uncoiling mechanism, and then sequentially passing through a leveling mechanism and a plate shearing mechanism to form a steel plate meeting the size requirements;

[0030] S2, the motor is driven in the forward direction to drive the movable gripping unit to the outside of the conveying mechanism, and the cylinder is actuated to adjust the gripping plate to a horizontal state;

[0031] S3, the first hydraulic cylinder is lowered to make the suction cup adhere to the steel plate, the suction cup is suctioned, the steel plate is adsorbed by the suction cup, and the first hydraulic cylinder is lifted to make the steel plate separate from the conveying mechanism;

[0032] S4, the motor is driven in the reverse direction to drive the movable gripping unit to the outside of the stacking table, and the cylinder is actuated to make the steel plate form an angle of 5°-10° with the horizontal plane and the side of the steel plate close to the first hydraulic cylinder contact the top of the stacking table;

[0033] S5, the suction cup is inflated, the steel plate separates from the suction cup, the other side of the steel plate rotates along one side of the steel plate and falls to adhere to the top of the stacking table, and the action is completed.

[0034] By adopting the technical scheme, the slitting process from the steel coil to the steel plate is smoother, and the movable gripping unit is provided to ensure that the steel plates can be reliably stacked together after slitting, and the stacking process can prevent the steel plates from being bent or deformed due to collision, and can also prevent impurities between the steel plates and the stacking table or between the steel plates from causing defects such as depressions or scratches on the surface of the steel plates, thereby improving the finished product quality of the steel plates.

[0035] In summary, the application has the following beneficial effects:

[0036] 1. By horizontal gripping and vertical lowering of the movable gripping unit, the steel plate is in a horizontal state during movement and lowering, which can prevent the four corners or one side of the steel plate being lowered from colliding with the stacking table or the steel plates on the stacking table, so that the steel plate will not produce large deformation or defects during stacking.

[0037] 2. The horizontal grabbing is carried out by the movable grabbing unit, and the inclination angle of the grabbing plate is adjusted by the cylinder, so that the steel plate is formed to rotate and press down, and the air between the steel plate and the stacking table is removed in a certain direction in the process of rotating and pressing down, so that the sundries between the steel plate and the stacking table can be more effectively taken out, and the sundries with small volume can be prevented from causing concave or scratch on the surface of the steel plate after the steel plate contacts with the stacking table.

[0038] 3. The impact between the steel plate and the limiting plate drives the limiting plate to move as a whole and the spring to stretch and store energy to realize the buffering effect, and then the spring rebounds, that is, the second hydraulic cylinder is pulled to realize the reset of the offset steel plate and neatly stack on the stacking table.

DETAILED DESCRIPTION

[0047] The present application will be further described in detail below in combination with the accompanying drawings. Figures 1-7 ​

[0048] Figure 1 is a schematic perspective view of the present application, Figure 2 is a schematic perspective view of the stacking mechanism in the present application. Referring to Figure 1 The fine steel plate slitting equipment comprises an uncoiling mechanism 1, a leveling mechanism 2, a plate shearing mechanism 3, a conveying mechanism and a stacking mechanism 4, the steel coil is formed into a steel plate 5 after uncoiling, leveling and transverse cutting, the steel plate 5 is stacked in the stacking mechanism 4, the stacking mechanism 4 comprises a stacking table 41 and a movable grabbing unit 42 arranged on one side of the stacking table 41, the movable grabbing unit 42 grabs the steel plate 5 waiting to be stacked on the conveying mechanism and places it on the stacking table 41; the movable grabbing unit 42 comprises an inverted L-shaped support 421, a grabbing plate 422, a first hydraulic cylinder 423 and a suction cup 424, the first hydraulic cylinder 423 is connected with the vertical end of the support 421 and drives the support 421 to move up and down, the first hydraulic cylinder 423 is arranged on a moving platform 425, referring to Figure 2 The top of the moving platform 425 is provided with a sliding groove 4251 extending along the sliding direction of the steel plate 5, the sliding groove 4251 is provided with a lead screw 4253 driven by a motor 4252, the lead screw 4253 is threadedly connected with a sliding seat 4254, the outer wall of the sliding seat 4254 is attached to the inner wall of the sliding groove 4251, and the top of the moving platform 425 is provided with a connecting plate 4255 for connecting the first hydraulic cylinder 423 and the sliding seat 4254.

[0049] The driving of the lead screw 4253 by the motor 4252 and the restriction of the sliding seat 4254 by the sliding groove 4251 and the limiting plate 414 enable the sliding seat 4254 to drive the movable grabbing unit to displace along the extension direction of the sliding groove 4251, that is, reciprocate between the conveying mechanism and the stacking mechanism 4, so that the steel plate 5 is adsorbed and placed on the stacking table 41 by the suction cup 424 below the grabbing plate 422, since the grabbing plate 422 is connected with the support 421 and the support 421 is connected with the first hydraulic cylinder 423, the height adjustment of the steel plate 5 can be realized by the up-and-down telescoping of the first hydraulic cylinder 423 under the premise of maintaining the horizontal posture of the steel plate 5, which can prevent the collision between the surrounding corners or one side edge of the steel plate 5 being placed and the stacking table 41 or the steel plate 5 on the stacking table 41, so that the steel plate 5 will not be deformed or defective in the stacking process, thereby avoiding the reduction of the finished product quality of the steel plate 5 in the stacking process.

[0050] Figure 3 is a schematic front view of the stacking mechanism in the present application, Figure 4 is Figure 3 is a reference diagram of the action state of Figure 3 and Figure 4In order to realize automatic blowing of the fine sundries between the steel plate 5 and the stacking table 41 or the steel plate 5 and the steel plate 5, one side of the grabbing plate 422 is hinged to the vertical end of the support 421, and a movable seat 4220 is arranged at the top of the other side of the grabbing plate 422, the movable seat 4220 is displaced by the air cylinder 4210, and then the other side of the grabbing plate 422 rotates around one side of the grabbing plate 422 to form an included angle of 5-10°. In this way, after one side of the grabbing plate 422 contacts the stacking table 41, the suction cup 424 releases the suction of the steel plate 5, so that the steel plate 5 rotates and presses down around one side of the steel plate 5. Since the distance between the steel plate 5 and the stacking table 41 gradually decreases, the air between the steel plate 5 and the stacking table 41 flows rapidly from one side of the steel plate 5 to the other side of the steel plate 5, and in the process of air flow, the sundries between the steel plate 5 and the stacking table 41 are automatically taken out, without manual cleaning, and the appearance defects caused by the collision between the steel plate 5 and the sundries after falling can be effectively prevented.

[0051] Figure 5 is a schematic top view of the stacking table. Referring to Figure 5 By arranging the limiting plates 414 on three sides of the outer wall of the stacking table 41, the limiting effect of the steel plate 5 can be realized, and the large displacement of the steel plate 5 after rotating and pressing down can be prevented.

[0052] Figure 6 is a schematic sectional view taken along the section line A-A in Figure 5 Figure 7 is a motion state reference view of Figure 6 . Referring to Figure 6 and Figure 7 ​Further, in order to reduce the impact of the steel plate 5 on the limiting plate 414, and to enable the limiting plate 414 to reset the steel plate 5 after the steel plate 5 is misaligned, the limiting plate 414 is arranged in a right L shape, and a containing groove 411 for placing the limiting plate 414 is arranged on the outer wall of the stack 41. The containing groove 411 is also provided with a second hydraulic cylinder 412 and a spring 413. One end of the spring 413 is fixedly connected with the containing groove 411, and the other end of the spring 413 is fixedly connected with the horizontal end of the limiting plate 414. The push rod of the second hydraulic cylinder 412 is connected with the horizontal end of the limiting plate 414 through a pull rope 415. In this way, the horizontal end of the limiting plate 414 is pushed by the second hydraulic cylinder 412, so that the limiting plate 414 as a whole moves away from the stack 41. At this time, the spring 413 is in a semi-stretched state, and the pull rope 415 is in a relaxed state. Thus, the action space of the steel plate 5 after rotating and pressing is provided, so that the impact between the steel plate 5 and the limiting plate 414 is reduced or avoided. If the steel plate 5 still impacts the limiting plate 414 after displacement, the spring 413 can be further stretched, and the pull rope 415 is gradually tensioned, thereby playing a buffering role on the steel plate 5 and a limiting role on the limiting plate 414. After the displacement of the steel plate 5 is completed, on the one hand, the spring 413 can be used to reset the limiting plate 414 and the steel plate 5, and on the other hand, the second hydraulic cylinder 412 can be used to pull the pull rope 415 to promote the reset of the limiting plate 414 and the steel plate 5. At the same time, since the second hydraulic cylinder 412 and the limiting plate 414 are connected in a soft connection mode, after the steel plate 5 is displaced by a distance and impacts the limiting plate 414, the limiting plate 414 only drives the spring 413 to continue to stretch and the pull rope 415 to be tensioned, so that the impact of the steel plate 5 on the limiting plate 414 can be avoided, thereby effectively protecting the push rod of the second hydraulic cylinder 412.

[0053] Referring to Figure 5 By arranging a pair of grooves 416 on the top of the stack 41, the steel plate 5 on the stack 41 can be packaged or lifted through the grooves 416. In this way, the steel plate 5 on the stack 41 can be wrapped as a whole, thereby facilitating storage and transportation.

[0054] The use method of the high-quality steel plate slitting equipment is as follows: including the following steps: S1, the steel coil is placed in the unwinding mechanism 1, and then sequentially passes through the leveling mechanism 2 and the plate shearing mechanism 3 to form a steel plate 5 meeting the size requirements;

[0055] S2, the motor 4252 is positively driven to drive the movable grabbing unit 42 to the outside of the conveying mechanism 6, and the cylinder 4210 is driven to adjust the grabbing plate 422 to a horizontal state;

[0056] S3, the first hydraulic cylinder 423 is pressed down, so that the suction cup 424 is attached to the steel plate 5, the suction cup 424 is pumped, the steel plate 5 is adsorbed by the suction cup 424, the first hydraulic cylinder 423 is lifted up, so that the steel plate 5 is separated from the conveying mechanism 6;

[0057] S4, the motor 4252 is reversely operated to drive the movable gripping unit 42 to the outside of the stacking table 41, the cylinder 4210 is operated to make the steel plate 5 form an angle of 5°-10° with the horizontal plane, and the steel plate 5 is in contact with the top of the stacking table 41 on the side close to the first hydraulic cylinder 423;

[0058] S5, the suction cup 424 is inflated, the steel plate 5 is separated from the suction cup 424, the other side of the steel plate 5 is turned down along one side of the steel plate 5 and attached to the top of the stacking table 41, and the operation is completed.

[0059] Through the above steps, the steel plate 5 can be slitting and stacking after slitting, and the stacking process can prevent the steel plate 5 from being bent and deformed due to collision, and can also prevent the steel plate 5 and the stacking table 41 or the steel plate 5 and the steel plate 5 from producing defects such as indentation or scratch on the surface of the steel plate 5, thereby improving the finished product quality of the steel plate 5.

[0060] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
