Abstract
Description
Technical Field
[0001] The invention relates to multifunctional cold rolling equipment. Background Art
[0002] Hot-rolled steel coils are used as raw materials, and after pickling to remove the oxide scale, cold rolling is carried out. The finished product is hard-rolled coils. Due to the cold work hardening caused by continuous cold deformation, the strength and hardness of the hard-rolled coils increase, and the toughness and plasticity index decrease. Therefore, the stamping performance will deteriorate and it can only be used for parts with simple deformation. Hard-rolled coils can be used as raw materials for hot-dip galvanizing plants, because hot-dip galvanizing units are equipped with annealing lines. Cold-rolled plates need to be rolled using cold rolling rollers. When the elastic flattening value of the rollers needs to be reduced, the diameter of the rollers must be reduced. When the diameter of the rollers is reduced, the roller stiffness is insufficient, resulting in a decrease in cold rolling accuracy. Summary of the invention
[0003] Based on this, it is necessary to provide a multifunctional cold rolling equipment with high cold rolling precision and high roll stiffness.
[0004] A multifunctional cold rolling equipment includes an installation component, a first rolling roller component and a second rolling roller component, the installation component includes a base plate and a support frame, the support frame is installed at one end of the base plate, the first rolling roller component is arranged on the base plate and adjacent to the support frame, the second rolling roller component is arranged above the first rolling roller component, the first rolling roller component includes a first rolling roller and two second rolling rollers abutting above the first rolling roller, the second rolling roller component includes a third rolling roller and two fourth rolling rollers supported below the third rolling roller, a cold rolling gap is formed between the first rolling roller and the third rolling roller, the diameter of the second rolling roller is larger than the diameter of the first rolling roller, and the diameter of the fourth rolling roller is larger than the diameter of the third rolling roller.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0021] The present invention relates to a multifunctional cold rolling equipment. For example, the multifunctional cold rolling equipment includes a mounting assembly, a first rolling roller assembly and a second rolling roller assembly, the mounting assembly includes a base plate and a support frame, and the support frame is mounted on one end of the base plate. For example, the first rolling roller assembly is arranged on the base plate and adjacent to the support frame, the second rolling roller assembly is arranged above the first rolling roller assembly, and the first rolling roller assembly includes a first rolling roller and two second rolling rollers abutting against the first rolling roller. For example, the second rolling roller assembly includes a third rolling roller and two fourth rolling rollers supported below the third rolling roller, and a cold rolling gap is formed between the first rolling roller and the third rolling roller. For example, the diameter of the second rolling roller is larger than the diameter of the first rolling roller, and the diameter of the fourth rolling roller is larger than the diameter of the third rolling roller.
[0022] See also Figures 1 to 3 A multifunctional cold rolling equipment comprises an installation component 10, a first rolling roller component 20 and a second rolling roller component 30, wherein the installation component 10 comprises a base plate 11 and a support frame 13, wherein the support frame 13 is installed at one end of the base plate 11, the first rolling roller component 20 is arranged on the base plate 11 and adjacent to the support frame 13, the second rolling roller component 30 is arranged above the first rolling roller component 20, the first rolling roller component 20 comprises a first rolling roller 21 and two second rolling rollers 22 abutting against the first rolling roller 21, the second rolling roller component 30 comprises a third rolling roller 31 and two fourth rolling rollers 32 supported below the third rolling roller 31, a cold rolling gap 215 is formed between the first rolling roller 21 and the third rolling roller 31, the diameter of the second rolling roller 22 is larger than the diameter of the first rolling roller 21, and the diameter of the fourth rolling roller 32 is larger than the diameter of the third rolling roller 31.
[0023] When the multifunctional cold rolling equipment is in use, the plate body 80 is conveyed to the cold rolling gap 215 for cold rolling. Since the diameters of the first rolling roller 21 and the third rolling roller 31 are relatively small, the plate body 80 can be cold rolled to a smaller thickness. The two second rolling rollers 22 with larger diameters press against the first rolling roller 21, and the two fourth rolling rollers 32 with larger diameters press against the third rolling roller 31. Therefore, the stiffness of the first rolling roller 21 and the third rolling roller 31 can be relatively improved, thereby improving the cold rolling accuracy.
[0024] For example, in order to facilitate supporting the plate body 80 output by cold rolling, the installation assembly 10 further includes a support platform 14, the support platform 14 is installed on the bottom plate 11, and the top surface of the support platform 14 is flush with the top of the third roller 31. The support frame 13 includes two support plates 131 and an extension plate 133, the two support plates 131 are respectively vertically protruded on the opposite sides of the bottom plate 11, and the extension plate 133 is arranged on the top of the two support plates 131. The support platform 14 is located between the two support plates 131, and the distance between the extension plate 133 and the bottom plate 11 is greater than the height of the support platform 14. The extension direction of the extension plate 133 is parallel to the length direction of the bottom plate 11, and the opposite sides of the extension plate 133 are respectively vertically connected to the two support plates 131. By arranging the support platform 14 between the two support plates 131, it is convenient to use the support platform 14 to support one end of the plate body 80 output by cold rolling, thereby improving the output stability of the plate body 80.
[0025] For example, in order to facilitate more stable support of the plate body 80, the diameter of the first roller 21 is equal to the diameter of the third roller 31. The diameter of the second roller 22 is equal to the diameter of the fourth roller 32. The circumferences of the two second rollers 22 are tangent to the circumference of the first roller 21, and the circumferences of the two second rollers 22 are tangent. The circumferences of the two fourth rollers 32 are tangent to the circumference of the third roller 31, and the circumferences of the two fourth rollers 32 are tangent. A lubricating oil tank 135 is installed on the extension plate 133, and a dripping oil pipe is provided at the bottom of the lubricating oil tank 135. The dripping oil pipe extends toward the bottom plate 11, and the extension axis of the dripping oil pipe is located between the two second rollers 22. By utilizing the tangent of the two second rollers 22 to the first roller 21 and the tangent of the two fourth rollers 32 to the third roller 31, the positioning stability of the first roller 21 and the third roller 31 is improved. The provision of the oil dripping pipe facilitates the use of lubricating oil to lubricate the first roller assembly 20. It is understood that the lubricating oil can also be dripped from the first roller 21 to the third roller 31 to implement lubrication of the second roller assembly 30. It is understood that the first roller assembly 20 and the second roller assembly 30 can be supported by a pivoting frame, and the pivoting frame can rotatably support the first roller 21, the second roller 22, the third roller 31 and the fourth roller 32. Specifically, the pivoting frame is not shown in the drawings.
[0026] For example, it is particularly important that, in order to facilitate the realization of more functions, for example, in order to realize the cutting function, the mounting assembly 10 further includes a mounting plate 16, the mounting plate 16 is protruding from one side of the bottom of the support platform 14, and the mounting plate 16 extends in a direction away from the bottom plate 11. The multifunctional cold rolling equipment further includes a cutting assembly 40, the cutting assembly 40 includes a fixing frame 41, a driving motor 42 and a cutting wheel 43. The fixing frame 41 includes two connecting plates 411 and a transverse plate 415, the two connecting plates 411 are respectively vertically mounted on opposite sides of the mounting plate 16, and opposite ends of the transverse plate 415 are respectively connected to the top ends of the two connecting plates 411. The distance between the two connecting plates 411 is smaller than the width of the plate body 80. The two connecting plates 411 are respectively provided with reinforcing strips 412 on the sides facing each other. The two connecting plates 411 are provided with guide grooves 416 on the sides facing each other. The width of the guide grooves 416 is equal to the thickness of the plate body 80. The two guide grooves 416 are used to penetrate the opposite sides of the plate body 80 to receive the plate body 80 outputted by cold rolling and to limit the plate body 80 to prevent the plate body 80 from arching when subjected to force. The driving motor 42 is installed at the end of the transverse plate 415. The cutting wheel 43 is rotatably installed at the middle of the transverse plate 415 and connected to the driving motor 42. The rotation axis of the cutting wheel 43 is parallel to the length direction of the transverse plate 415. The driving motor 42 is used to drive the cutting rotation, thereby driving the cutting wheel 43 to cut the middle of the plate body 80, so as to cut the plate body 80 into two half plates from the center line.
[0027] For example, in order to facilitate the plate body 80 to be led out, the multifunctional cold rolling equipment further includes a guide assembly 50, the guide assembly 50 includes a flip plate 51 and an adjusting stud 52, one end of the flip plate 51 is rotatably connected to the end of the mounting plate 16 away from the bottom plate 11, the other end of the flip plate 51 is provided with a narrow slot 511, and the end of the flip plate 51 is overlapped and supported on the end of the extension plate 133. The flip plate 51 is arranged obliquely relative to the mounting plate 16. A lead-out groove 512 is provided in the middle of the flip plate 51, and the lead-out groove 512 is aligned with the cold rolling gap 215, and is used for the plate body 80 to pass through and lead out the plate body 80. The distance between the upper and lower edges of the lead-out groove 512 is greater than the thickness of the plate body 80, and the narrow slot 511 passes through the end of the flip plate 51 and extends toward the lead-out groove 512. The cutting wheel 43 partially protrudes into the narrow slot 511. The adjusting stud 52 is obliquely protruded at the end of the extension plate 133 and penetrates the narrow slot 511. The extending direction of the adjusting stud 52 is perpendicular to the length direction of the flip plate 51. The adjusting stud 52 is screwed with a first nut 521 and a second nut 522. The first nut 521 and the second nut 522 are respectively located on the top surface and the bottom surface of the flip plate 51. By setting the flip plate 51, the flying chips generated by the cutting wheel 43 can be blocked, and by setting the lead-out groove 512, the cut plate 80 can be supported and led out. When the plate 80 does not need to be led out from the rear end, the first nut 521 and the second nut 522 are rotated to drive the flip plate 51 to rotate to raise the position of the lead-out groove 512, so that the lead-out groove 512 is misaligned with the cold rolling gap 215, and then the plate 80 is blocked to prevent the plate 80 from being output from the rear end. In summary, by providing the flip plate 51, it is convenient to control the flip plate 51 to lead out or not lead out the plate body 80. The flip plate 51 can also block flying chips generated during cutting.
[0028] For example, in order to stack the two cut half-plate bodies in sequence from the bottom of the mounting plate 16, a material guide groove 165 is provided through the end region where the mounting plate 16 is connected to the flip plate 51. The material guide groove 165 extends toward the support frame 13. The material guide groove 165 is a rectangular groove. The width of the material guide groove 165 is 0.5-0.7 times the width of the plate body 80. A first wedge-shaped protrusion 166 and a second wedge-shaped protrusion 168 are provided on the surface of the flip plate 51 facing the mounting plate 16. The first wedge-shaped protrusion 166 and the second wedge-shaped protrusion 168 are respectively adjacent to the opposite side edges of the flip plate 51 and are both located at one end of the flip plate 51 adjacent to the material guide groove 165. The thickness of the first wedge-shaped protrusion 166 and the thickness of the second wedge-shaped protrusion 168 both gradually decrease in the direction toward the lead-out groove 512, the maximum thickness of the first wedge-shaped protrusion 166 is greater than the maximum thickness of the second wedge-shaped protrusion 168, the thickness change rate of the first wedge-shaped protrusion 166 is greater than the thickness change rate of the second wedge-shaped protrusion 168, and the first wedge-shaped protrusion 166 and the second wedge-shaped protrusion 168 are smoothly connected. One end of the first wedge-shaped protrusion 166 is protruded in the guide groove 165, and one end of the second wedge-shaped protrusion 168 is protruded at the edge of the guide groove 165 away from the support frame 13. The guide assembly 50 also includes two inclined plates 54, which are respectively arranged on opposite sides of the guide groove 165, and the distance between the two inclined plates 54 gradually increases in the direction of height upward. The top edges of the two inclined plates 54 are respectively flush with the two reinforcement strips 412, and the tops of the inclined plates 54 are fixedly connected to the corresponding reinforcement strips 412.
[0029] When the two cut half plates need to be stacked and led out from the guide groove 165, the first nut 521 and the second nut 522 are rotated to adjust the tilt angle of the flip plate 51, so that the lead-out groove 512 is located above the plate 80 to block the plate 80, so that the plate 80 can only bend and move downward along the flip plate when subjected to force. Thereafter, the cut plate 80 forms two half plates, the ends of which are both against the flip plate 51. Under the thrust of cold rolling, the two half plates are respectively bent and moved downward under the guidance of the first wedge-shaped protrusion 166 and the second wedge-shaped protrusion 168, so that the half plate on the first wedge-shaped protrusion 166 has a larger curvature and is arranged in the middle of the guide groove 165, and the half plate on the second wedge-shaped protrusion 168 has a smaller curvature and is arranged at the edge of the guide groove 165. During the movement of the two half-plates, the surfaces of the two inclined plates 54 press against the sides of the two half-plates that are away from each other, and the half-plates on the first wedge-shaped protrusion 166 and the half-plates on the second wedge-shaped protrusion 168 are deflected and moved toward the middle of the guide groove 165, and finally the two half-plates are stacked on each other and bent downwardly from the guide groove 165. The first wedge-shaped protrusion 166 and the second wedge-shaped protrusion 168 are provided so that the two half-plates are arranged in a sequential order, and the provision of the two inclined plates 54 enables the two half-plates to be pushed against each other and then stacked on each other to align with the guide groove 165, and finally output from the guide groove 165.
