Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of slitting machine unit, in particular to a stainless steel plate single knife seat longitudinal shear slitting machine unit. BACKGROUND

[0002] The stainless steel plate single knife seat longitudinal shear slitting machine unit is a special automatic equipment for longitudinal shear slitting of stainless steel plate, and mainly functions to shear wide stainless steel coil plate into multiple narrow standard steel strips along the length direction, and is widely applied to stainless steel processing, automobile manufacturing, household appliance production and building material industry. Wide stainless steel coil plate is expanded by an uncoiler, is corrected in position by a guide device, and is stably sent into a single knife seat shearing unit. The stainless steel plate single knife seat longitudinal shear slitting machine unit is a special equipment for longitudinal slitting of stainless steel plate, and the core is to realize shearing of wide plate into narrow strip through a single knife seat and a disc cutter. The stainless steel plate single knife seat longitudinal shear slitting machine unit has the characteristics of simple structure, controllable precision and adaptability to multiple specifications, and is a key equipment for realizing material standardization in the stainless steel deep processing link.

[0003] The existing stainless steel plate single knife seat longitudinal shear slitting machine unit is mainly used for cutting stainless steel plate. In the process of cutting thick plate, the thick plate is mostly stainless steel plate with a thickness not less than 5mm, and the rigidity of the thick plate is much higher than that of the thin plate. When a single knife seat is used for cutting, the shearing force of the cutter on the plate will cause instantaneous plastic deformation of the contact area. However, the overall plate is difficult to buffer the force due to the excessive rigidity, the reaction force will be transmitted to the knife seat through the cutter, causing high-frequency vibration of the knife seat in the vertical direction, and then causing the cutter to vibrate up and down. When the cutter vibrates up and down, the contact point of the cutter and the plate will produce periodic deviation of 0.1-0.5mm in the vertical direction and the horizontal direction, resulting in that the cutting edge cannot be stably sheared along the preset trajectory. However, most of the existing stainless steel plate single knife seat longitudinal shear slitting machine units have anti-vibration processing function, so as to meet the precision machining requirement.

[0036] In this embodiment, when the stainless steel plate is moved out from between the outer surfaces of the two blade shafts 302, one end of the stainless steel plate is wound on the surface of the winding device 6, wherein, as shown in Figure 1As shown, the winding device 6 is composed of a winding machine and a driving device, which can realize winding of the slit stainless steel plate. At this time, the outer surface of the stainless steel plate is just arranged at the top of the protection assembly 5, that is, the servo motor 502 is started to drive the driving pipe 503 to rotate, and then drive the driving gear 504 to rotate, so as to drive the driven gear 505 to rotate, and then make the positioning sleeve 506 rotate, so as to drive the plurality of supporting members 511 to rotate. When one group of parallel supporting members 511 rotates to the outside of the limiting sleeve 514, the spring 512 corresponding to the group of supporting members 511 is no longer extruded by the limiting sleeve 514, so that the group of supporting members 511 is elongated under the elastic action of the spring 512, and then drives the group of supporting members 511 to move upward, until the sealing rubber ring 513 arranged on the outer surface of the group of supporting members 511 is tightly attached to the bottom of the stainless steel plate. At the same time, when the group of supporting members 511 rotates to the top, the group of hollow pipes 510 is just fixedly communicated between the plurality of butt joints 509. The outer surface of the hollow pipe 510 is provided with a sealing ring, which is used to improve the sealing strength between the hollow pipe 510 and the butt joint 509. At this time, the negative pressure pump 508 can be started to extract gas from the inside of the vacuum pipe 507, and then extract gas from the sealing space between the group of supporting members 511 arranged at the uppermost position and the stainless steel plate, so that the inside is in a negative pressure state, thereby further enhancing the connection strength of the sealing rubber ring 513 arranged on the surface of the supporting member 511 and the stainless steel plate, and effectively preventing the stainless steel plate from being unable to meet the precision machining requirements of the stainless steel plate due to the vibration of the cutter shaft 302 after slitting. Then the driving motor 306 can be started to drive the two upper gears 304 to rotate, and then drive the two lower gears 305 to rotate, so that the two cutter shafts 302 rotate in opposite directions, thereby cutting the stainless steel plate. In the cutting process, the stainless steel plate is effectively fixed before and after cutting, the vibration energy generated by the vibration of the cutter shaft 302 is hindered when transmitted to the plate, and it is difficult to form a resonance amplification effect on the plate, thereby reducing the vibration amplitude transmitted to the plate, reducing the influence of vibration on cutting precision, thereby ensuring the cutting accuracy, and solving the problem that the cutter shakes up and down to reduce the machining precision when cutting the thick plate in the prior art.

[0037] As Figure 1 and Figures 6-10As shown, a stainless steel plate single knife seat longitudinal cutting slitting machine set, including a compression plate 1, the top of the compression plate 1 is provided with a flattening device 2 near one side edge for flattening the stainless steel plate, the top of the compression plate 1 is provided with a slitting assembly 3 near the center for slitting the stainless steel plate, the top of the compression plate 1 is provided with a positioning assembly 4 for preventing the stainless steel plate from vibrating before slitting, the top of the compression plate 1 is provided with a protection assembly 5 near the other side edge for preventing the stainless steel plate from vibrating, the protection assembly 5 includes a vacuum pipe 507, a plurality of docking interfaces 509 for communicating with external devices are uniformly arranged on the top of the vacuum pipe 507, a positioning sleeve 506 is rotatably arranged on the outer surface of the vacuum pipe 507, a plurality of springs 512 are arranged on the inner wall of the positioning sleeve 506, one end of each of the plurality of springs 512 is provided with a support 511 for supporting the stainless steel plate, a sealing rubber ring 513 for adsorbing the stainless steel plate is coupled and connected to the outer surface of each of the plurality of supports 511, and a limiting sleeve 514 is arranged between the outer surfaces of the plurality of supports 511.

[0038] In this embodiment, when the cut stainless steel plate is positioned by the uppermost support 511, in order to facilitate the subsequent winding of the winding device 6, the servo motor 502 is started again to rotate the positioning sleeve 506, so that the uppermost set of hollow pipes 510 is separated from the corresponding docking interfaces 509, so that the inside of the set of supports 511 is filled with gas, and the uppermost set of sealing rubber rings 513 is separated from the outer surface of the stainless steel plate. When the set of supports 511 rotates to a position corresponding to the extrusion rod 515, another set of supports 511 is rotated to the top of the vacuum pipe 507, and the set of hollow pipes 510 is fixedly communicated between the plurality of docking interfaces 509. At the same time, the multi-stage electric telescopic rod 518 is started to extend, driving the connecting frame 516 to move forward, and then the connecting frame 516 extrudes the set of supports 511 corresponding to it, driving the springs 512 corresponding to the set of supports 511 to shorten, until the extrusion rod 515 and the limiting sleeve 514 form a complete arc, that is, the set of supports 511 is reset. Through the resetting of the supports 511, the continuity of the positioning of the stainless steel plate is realized, and the cutting accuracy of the stainless steel plate is further ensured.

[0039] The method for using the device and the working principle: when the single-blade longitudinal cutting and slitting machine group is needed to cut and slit the stainless steel plate, first, the stainless steel plate is sleeved on the flattening device 2, and the stainless steel plate is flattened through the flattening device 2, then the electric push rod 402 is started to be elongated or shortened, driving the two extrusion pieces 403 to move towards the fixed frame 404, when the two positioning rods 405 are pushed by the two extrusion pieces 403 to make the distance between them larger, the four corresponding elastic pieces 407 are all shortened under extrusion, then the stainless steel plate is inserted between the outer surfaces of the two positioning rods 405, then the electric push rod 402 is started again to be shortened, driving the two extrusion pieces 403 to move back, and then the two positioning rods 405 move towards each other under the elastic action of the elastic pieces 407, so as to clamp the stainless steel plate, then the two pressure sensors 406 are started respectively through the external control device, the extrusion of the two positioning rods 405 on the stainless steel plate is detected through the pressure sensors 406, when the two pressure sensors 406 detect that the extrusion of the two positioning rods 405 on the stainless steel plate reaches the required value, the electric push rod 402 can be closed, and one end of the stainless steel plate is inserted between the outer surfaces of the two corresponding knife shafts 302, that is, the positioning of the stainless steel plate before being cut is completed, then the driving motor 306 is started to drive the two upper gears 304 to rotate, and then the two lower gears 305 are rotated, so that the two knife shafts 302 rotate in opposite directions, and then the stainless steel plate is cut, when the stainless steel plate is removed from between the outer surfaces of the two knife shafts 302, one end of the stainless steel plate is wound on the surface of the winding device 6, at this time, the outer surface of the stainless steel plate is arranged at the top of the protection assembly 5, the servo motor 502 is started to drive the driving pipe 503 to rotate, and then the driving gear 504 is rotated, so that the driven gear 505 is rotated, and then the positioning sleeve 506 is rotated, so as to drive the plurality of supporting pieces 511 to rotate, when one of the parallel supporting pieces 511 rotates to the outside of the limiting sleeve 514, the spring 512 corresponding to the supporting piece 511 is no longer extruded by the limiting sleeve 514, so that the supporting piece 511 is elongated under the elastic action of the spring 512, and then the supporting piece 511 moves upwards, until the sealing rubber ring 513 arranged on the outer surface of the supporting piece 511 tightly contacts the bottom of the stainless steel plate, and at the same time, when the supporting piece 511 rotates to the top, the hollow pipe 510 is in communication with the plurality of butt joints 509, at this time, the negative pressure pump 508 is started to extract gas from the inside of the vacuum pipe 507, and then the gas in the sealed space between the uppermost supporting piece 511 and the stainless steel plate is extracted, so that the inside is in a negative pressure state, then the driving motor 306 is started to drive the two upper gears 304 to rotate, and then the two lower gears 305 are rotated, so that the two knife shafts 302 rotate in opposite directions, so as to slit the stainless steel plate.During the cutting process, the stainless steel plate is effectively fixed both before and after cutting. When the vibration energy generated by the vibration of the cutter shaft 302 is transmitted to the plate, the transmission is hindered due to the plate's firm fixation, making it difficult to form a resonance amplification effect on the plate. This reduces the amplitude of the vibration transmitted to the plate. After the cut stainless steel plate is positioned by the uppermost support member 511, the servo motor 502 can be restarted to facilitate the subsequent winding of the winding device 6. This drives the positioning sleeve 506 to rotate, causing the uppermost set of hollow tubes 510 to separate from the corresponding interface 509. This allows gas to fill the support member 511, thereby allowing the uppermost hollow tube 510 to rotate. One set of sealing rubber rings 513 at the top separates from the outer surface of the stainless steel plate. When this set of support members 511 rotates to the position corresponding to the extrusion rod 515, another set of support members 511 rotates to the top of the vacuum tube 507, and this set of hollow tubes 510 is fixedly connected to multiple mating interfaces 509. At the same time, the multi-stage electric telescopic rod 518 is activated, extending it and driving the connecting frame 516 forward. This causes the connecting frame 516 to extrude the corresponding set of support members 511, causing the spring 512 corresponding to that set of support members 511 to shorten, until the extrusion rod 515 and the limiting sleeve 514 form a complete arc, thus completing the reset of the set of support members 511.

The appropriate models are selected according to actual use. Therefore, the control methods and wiring arrangements of the drive motor 306, electric actuator 402, pressure sensor 406, servo motor 502, negative pressure pump 508, multi-stage electric telescopic rod 518, and winding device 6 will not be explained in detail.
