Description

Technical Field

[0001] The invention belongs to the technical field of stainless steel strip production, and in particular relates to a curved surface smoothing device for stainless steel strips. Background Art

[0002] Stainless steel strip is a metal strip with excellent corrosion resistance and strength, usually made of stainless steel alloy. It is often used to manufacture various industrial products and consumer goods, and is widely used due to its corrosion resistance, high temperature resistance and good mechanical properties. Stainless steel strip usually has different thicknesses and widths, and can be used in food processing, chemical industry, architectural decoration and automobile manufacturing. Its main components include chromium and nickel, among which chromium provides stainless steel with corrosion resistance, while nickel enhances its strength and toughness.

[0003] The stainless steel strip itself is made of stainless steel alloy, and its flatness needs to be adjusted during the production process. The existing stainless steel strip curved surface flattening device needs to repeatedly bend during the flattening process to make the curvature of the stainless steel strip as uniform as possible. During the processing, stainless steel strips of different thicknesses are subjected to the same extrusion force, resulting in different flatness of stainless steel strips of different thicknesses, thereby reducing the flattening effect of the stainless steel strip. In addition, since the stainless steel strip itself is relatively hard, the curvature of the processed stainless steel strip cannot be uniform, thereby greatly reducing the working performance of the stainless steel strip curved surface flattening device. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a curved surface smoothing device for a stainless steel strip.

[0005] The technical solution adopted to solve the above technical problems is: a curved surface flattening device for stainless steel strips, comprising a main body, a conveying groove is opened on the top of the main body, and a plurality of conveying rollers are rotatably connected inside the conveying groove; The outer wall of the conveying trough is rotatably fixedly connected to a processing cabinet, and both sides of the processing cabinet are provided with inlet and outlet ports; A driving mechanism is installed inside the processing cabinet, a connecting rod mechanism is installed inside the conveying trough, and a transmission mechanism is installed inside the conveying trough.

[0006] Further, the driving mechanism includes a first motor fixedly connected to the inside of the processing cabinet, the output end of the first motor is fixedly connected to the first driving shaft, the outer wall of the first driving shaft is fixedly connected to two first gears, the outer walls of the two first gears are meshed with two racks, one end of the plurality of racks is fixedly connected to a support column, the other end of the plurality of support columns is fixedly connected to a first support rod, a plurality of first support rods are provided with a first limiting groove inside, a plurality of first limiting grooves are slidably connected to a second support rod, a plurality of second support rods are fixedly connected to the front and rear ends of the outer walls of the front and rear ends, a plurality of first sliding grooves are provided at the front and rear ends of the transmission groove, and the interiors of the plurality of second support rods are rotatably connected to extrusion rollers, wherein the outer walls of the plurality of extrusion rollers are rotatably connected to the third support rod, the first driving shaft runs through the interior of the transmission groove, the two first gears are respectively located at the front and rear ends of the transmission groove, the height of the first limiting groove is higher than the second support rod, the tops of the plurality of first support rods are fixedly connected to a plurality of second support rods, and the interiors of the plurality of first sliding grooves are slidably connected to the corresponding extrusion rollers.

[0007] Through the above technical solution, when in use, when the stainless steel strip is conveyed to the processing cabinet through multiple conveyor rollers, the driving mechanism is used to unfold the entire device, so that it is convenient to extrude stainless steel strips of different thicknesses when they enter, thereby expanding the applicability of the entire curved surface smoothing device. At the same time, when the two ends are opened, they can be extruded forward and backward. Through preliminary extrusion and flattening, the surface of the stainless steel strip can be made smooth. The final extrusion and flattening can further correct and calibrate the flatness of the material, ensuring that the final product has higher flatness and consistency. Specifically, when the stainless steel strip is assisted by multiple conveyor rollers to be transported to a place close to the inlet and outlet, the first motor inside the processing cabinet is started at this time to drive the two first gears on the outer wall of the first drive shaft to rotate, and then the other end of the multiple racks The support column will push the multiple extrusion rollers on the second support rod to move to both sides along the first sliding groove and the second limiting groove respectively. Since one end of the second limiting groove is inclined, the two adjacent extrusion rollers are brought closer as they expand outward, thereby reducing the distance between them. Under the obstruction of the block, the second support rod at the bottom will rise along the first limiting groove along the inclination of the second limiting groove, thereby not hindering the movement of the entire device. In addition, as the support column moves to both sides, the third support rod is then driven to move, so that the stainless steel strip can easily enter smoothly before the leveling operation is performed, and can be selected for extrusion according to stainless steel strips of different thicknesses, and a certain pressure can be selected to ensure that the final product meets strict dimensional tolerance requirements and reduces processing errors.

[0008] Furthermore, the connecting rod mechanism includes a rotating shaft rotatably connected to the other end of a plurality of second support rods, the other ends of the outer walls of the plurality of rotating shafts are rotatably connected to two first connecting rods, two first rectangular grooves are opened at the front and rear ends of the transmission groove, and the plurality of first rectangular grooves are slidably connected with connecting shafts, wherein the outer walls of the plurality of connecting shafts are rotatably connected to second connecting rods, wherein the intersection of the two second connecting rods is rotatably connected to a first staggered roller, two second rectangular grooves are opened at the front and rear ends of the transmission groove, wherein the other ends of the plurality of second connecting rods are rotatably connected to second staggered rollers, and the front and rear ends of the transmission groove are opened with a plurality of second limiting grooves, the second connecting rod is retractable, and the interiors of the plurality of second rectangular grooves are respectively slidably connected to the corresponding first staggered rollers, and the plurality of second limiting grooves are respectively slidably connected to the corresponding second staggered rollers, and the length of the second limiting grooves is increasing.

[0009] Through the above technical solution, after the stainless steel strip enters the device, the connecting rod mechanism can be used to select its thickness, ensuring that stainless steel strips of different thicknesses can be subjected to a certain pressure selection before the curved surface is flattened, and the stainless steel strip can be bent repeatedly. After multiple plastic deformation processes, the organizational structure of the stainless steel strip will become more uniform, which may improve its mechanical properties, such as strength and hardness. This treatment can make the stainless steel strip more stable and durable in subsequent use, and make the surface curvature of the stainless steel strip uniform, achieving perfect leveling accuracy. Specifically, when a thinner stainless steel strip enters, as the support column moves, it will drive multiple connecting shafts to slide along the corresponding first rectangular grooves. At the same time, under the cross-connection of multiple second connecting rods, multiple second connecting rods are connected. An offset roller can slide on the corresponding second rectangular groove, and the second connecting rod is retractable, and then the second offset roller at the bottom will slide on different second limit grooves. The length of the second limit groove in the outermost circle is relatively long. Because under pulling, the outermost first offset roller and the second offset roller will move a longer distance under the cross-connection of multiple second connecting rods than the inner circle, which makes it easy to unfold the entire device. The first offset roller and the second offset roller are in the shape of a regular triangle, which is convenient for the stainless steel belt to enter from the middle. The thinner the thickness of the stainless steel belt, the greater the distance it needs to be pulled apart, so that its surface changes less and the curvature is smaller, which is more conducive to surface smoothing processing, thereby effectively removing surface defects such as corrugations, dents or scratches. The final leveling step helps to ensure that the material surface is smooth and flawless, thereby improving the appearance quality of the product.

[0010] Furthermore, the transmission mechanism includes a second motor fixed at the front end of the conveying groove, the output end of the second motor is fixedly connected to the second driving shaft, the outer wall of the second driving shaft is fixedly connected to two first synchronous wheels, the two first synchronous wheels, the outer walls of the two first synchronous wheels are rotatably connected to a synchronous belt, the inner walls of the two synchronous belts are rotatably connected to multiple second synchronous wheels, one end of the multiple connecting shafts is fixedly connected to the second gear, one end of the multiple first staggered rollers is fixedly connected to the third gear, the two first synchronous wheels are staggered, the multiple second gears are respectively meshed with the corresponding third gear, and the outer walls of the multiple connecting shafts are fixedly connected to the second synchronous wheels.

[0011] Through the above technical scheme, when the stainless steel belt is adjusted, the transmission mechanism is used for transmission, which is convenient for the smooth extrusion operation of the stainless steel belt and makes the surface of the stainless steel belt smoother. Specifically, when the device spreads to both sides, the two synchronous belts will become loose. Since the first connecting rod is longer than the second connecting rod, its inclination angle is smaller when moving under pulling, so that the synchronous belt can be supported. At the same time, under the change of the second connecting rod, the distance between its top rods remains unchanged, so that the second gear can be kept in mesh with the corresponding third gear respectively. In this state, the second motor at the front end of the conveying groove is started to drive the two first synchronous wheels on the outer wall of the second drive shaft to rotate, and then the two synchronous belts will drive the first staggered roller and the second staggered roller connected to the second synchronous wheel and the third gear to rotate, and multiple extrusion rollers also rotate at the same time, so as to extrude and flatten the stainless steel belt.

[0012] The beneficial effects of the present invention are as follows: (1) The present invention can adjust the stainless steel strip according to the specifications of the stainless steel strip during the curved surface flattening process by designing a driving mechanism, a connecting rod mechanism and a transmission mechanism. At the same time, the flattening adjustment is performed twice before the stainless steel strip enters the device and after the processing, so that the curved surface of the stainless steel strip can be adjusted more completely. In addition, the curvature of stainless steel strips of different thicknesses can be changed according to their different curvatures during flattening adjustment, which greatly improves the working performance of the curved surface flattening device. (2) The present invention can squeeze the stainless steel strip when it enters the device, then bend it repeatedly, and finally squeeze it again to keep it flat. The initial squeezing and flattening can remove the stainless steel strip produced during the production process. The subsequent repeated bending process helps to further homogenize the internal stress distribution of the material, and the final extrusion and flattening helps to eliminate any residual stress caused by bending, thereby improving the stability and strength of the material. At the same time, repeated bending can keep the curvature of the surface of the stainless steel strip uniform, making the surface flattening operation before shipment more effective; (3) The present invention designs a transmission mechanism. After stainless steel strips of different thicknesses enter the surface flattening device, the transmission mechanism can be adjusted as the changes occur, so that stainless steel strips of different thicknesses can smoothly enter the device for surface flattening processing. The device can automatically adjust the extrusion pressure according to the thickness of the stainless steel strip to ensure that each section of the stainless steel strip is processed evenly, thereby improving the consistency and quality of the final product.

DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

The support rod 608 is fixedly connected, and the interiors of the plurality of first sliding grooves 610 are slidably connected with the corresponding extrusion rollers 611. When in use, when the stainless steel strip is conveyed to the processing cabinet 4 by the plurality of conveyor rollers 3, the driving mechanism 6 is used to unfold the entire device, so that it is convenient to extrude stainless steel strips of different thicknesses when they enter, thereby expanding the applicability of the entire curved surface smoothing device. At the same time, when the two ends are opened, they can be extruded forward and backward. Through preliminary extrusion and smoothing, the surface of the stainless steel strip can be smoothed. The final extrusion and smoothing can further correct and calibrate the flatness of the material, ensuring that the final product has higher flatness and consistency. Specifically, when the stainless steel strip is assisted by the plurality of conveyor rollers 3 to be transported to a place close to the inlet and outlet 5, the first conveyor rollers 3 in the processing cabinet 4 are started at this time. A motor 601 drives the two first gears 603 on the outer wall of the first driving shaft 602 to rotate, and then the support column 605 at the other end of the multiple racks 604 will push the multiple squeezing rollers 611 on the second support rod 608 to move along the first sliding groove 610 and the second limiting groove 709 to both sides respectively. Since one end of the second limiting groove 709 is inclined, the two adjacent squeezing rollers 611 are brought closer as they are stretched out, thereby reducing the distance between them. Under the obstruction of the stopper 609, the second support rod 608 at the bottom will rise along the first limiting groove 607 along the inclination of the second limiting groove 709, thereby not hindering the movement of the entire device. In addition, as the support column 605 moves to both sides, it then drives the third support rod 612 to move.This allows the stainless steel strip to enter smoothly before the flattening operation, and can be extruded according to the different thicknesses of stainless steel strips, with a certain pressure selection, to ensure that the final product meets the strict dimensional tolerance requirements and reduce processing errors.

[0017] like Figure 9-10As shown, a connecting rod mechanism 7 is installed inside the conveying trough 2, and the connecting rod mechanism 7 includes a rotating shaft 701 rotatably connected to the other end of the plurality of second support rods 608, and the other ends of the outer walls of the plurality of rotating shafts 701 are rotatably connected to two first connecting rods 702, and the front and rear ends of the conveying trough 2 are provided with two first rectangular grooves 703, and the plurality of first rectangular grooves 703 are slidably connected with connecting shafts 704, wherein the outer walls of the plurality of connecting shafts 704 are rotatably connected to second connecting rods 705, wherein the intersection of the two second connecting rods 705 is rotatably connected to a first offset roller 706, and the front and rear ends of the conveying trough 2 are provided with two second rectangular grooves 707, wherein the other ends of the plurality of second connecting rods 705 are rotatably connected to second The dislocation roller 708 and the front and rear ends of the conveying groove 2 are provided with a plurality of second limiting grooves 709, the second connecting rod 705 is retractable, the interiors of the plurality of second rectangular grooves 707 are respectively slidably connected with the corresponding first dislocation rollers 706, and the plurality of second limiting grooves 709 are respectively slidably connected with the corresponding second dislocation rollers 708, and the length of the second limiting grooves 709 is increasing. After the stainless steel strip enters the device, the connecting rod mechanism 7 can be used to select its thickness, so as to ensure that stainless steel strips of different thicknesses can be subjected to a certain pressure selection before the curved surface is smoothed, and at the same time, the stainless steel strip can be bent repeatedly. After multiple plastic deformation processes, the organizational structure of the stainless steel strip will become more uniform. The treatment can make the stainless steel strip more stable and durable in subsequent use, and make the surface curvature of the stainless steel strip uniform, so as to achieve perfect leveling accuracy. Specifically, when the thinner stainless steel strip enters, the support column 605 moves, which drives the multiple connecting shafts 704 to slide along the corresponding first rectangular grooves 703. At the same time, under the cross connection of the multiple second connecting rods 705, the multiple first offset rollers 706 can slide on the corresponding second rectangular grooves 707, and the second connecting rod 705 is retractable. Then the second offset rollers 708 at the bottom will slide in different second limiting grooves 707. 9 slides on the outermost circle, the length of the second limiting groove 709 is relatively long, and under pulling, the outermost first offset roller 706 and the second offset roller 708 move a longer distance than the inner circle under the cross connection of multiple second connecting rods 705, so that it is convenient to unfold the entire device, and the first offset roller 706 and the second offset roller 708 are in the shape of a regular triangle, which is convenient for the stainless steel belt to enter from the middle. The smaller the thickness of the stainless steel belt, the greater the distance it needs to be pulled apart, so that the change of its surface is small, the curvature is small, and it is more conducive to surface smoothing processing, thereby effectively removing surface defects such as ripples, dents or scratches. The final smoothing step helps to ensure that the surface of the material is smooth and flawless, thereby improving the appearance quality of the product.

[0018] like Figure 5-Figure 7As shown, a transmission mechanism 8 is installed inside the conveying trough 2, and the transmission mechanism 8 includes a second motor 801 fixed to the front end of the conveying trough 2, and the output end of the second motor 801 is fixedly connected to the second driving shaft 802, and the outer wall of the second driving shaft 802 is fixedly connected to two first synchronous wheels 803, the two first synchronous wheels 803, the outer walls of the two first synchronous wheels 803 are rotatably connected to a synchronous belt 804, and the inner walls of the two synchronous belts 804 are rotatably connected to multiple second synchronous wheels 805, and one end of the multiple connecting shafts 704 is fixedly connected to a second gear 806, and one end of the multiple first offset rollers 706 is fixedly connected to a third gear 807, the two first synchronous wheels 803 are offset, and the multiple second gears 806 are respectively meshed with the corresponding third gear 807, and the outer walls of the multiple connecting shafts 704 are fixedly connected to the second synchronous wheels 805. When the stainless steel belt enters and the adjustment is completed, the transmission mechanism 8 is used for transmission, which is convenient for The smooth extrusion operation of the stainless steel belt makes the surface of the stainless steel belt smoother. Specifically, when the device spreads to both sides, the two synchronous belts 804 will become loose. Since the first connecting rod 702 is longer than the second connecting rod 705, its inclination angle is smaller when moving under pulling, so that the synchronous belt 804 can be supported. At the same time, under the change of the second connecting rod 705, the distance between its top rods remains unchanged, so that the second gear 806 can be kept meshed with the corresponding third gear 807 respectively. In this state, the second motor 801 at the front end of the conveying trough 2 is started to drive the two first synchronous wheels 803 on the outer wall of the second drive shaft 802 to rotate, and then the two synchronous belts 804 will drive the first staggered roller 706 and the second staggered roller 708 connected to the second synchronous wheel 805 and the third gear 807 to rotate, and at the same time, multiple extrusion rollers 611 also rotate, thereby performing an extrusion and smoothing operation on the stainless steel belt.

[0019] The working principle of this embodiment is as follows. Specifically, when the stainless steel belt is assisted by a plurality of conveyor rollers 3 to be transported to a position close to the inlet and outlet 5, the first motor 601 inside the processing cabinet 4 is started to drive the two first gears 603 on the outer wall of the first drive shaft 602 to rotate, and then the support column 605 at the other end of the plurality of racks 604 will push the plurality of squeezing rollers 611 on the second support rod 608 to move to both sides along the first sliding groove 610 and the second limiting groove 709, so that the two adjacent squeezing rollers 611 are close to each other as they are stretched outward. Under the obstruction of the stopper 609, the second support rod 608 at the bottom will rise along the first limiting groove 607 along the inclination of the second limiting groove 709. As the support column 605 moves to both sides, it will drive the plurality of connecting shafts 704 to move along the corresponding first rectangular grooves. 703, and at the same time, under the cross connection of multiple second connecting rods 705, multiple first offset rollers 706 can slide on the corresponding second rectangular grooves 707, and then the second offset rollers 708 located at the bottom will slide on different second limit grooves 709, and under the pulling, the stainless steel belt enters from between the first offset rollers 706 and the second offset rollers 708 for extrusion. In this state, the second motor 801 at the front end of the conveying groove 2 is started to drive the two first synchronous wheels 803 on the outer wall of the second driving shaft 802 to rotate, and then the two synchronous belts 804 will drive the first offset rollers 706 and the second offset rollers 708 connected to the second synchronous wheels 805 and the third gear 807 to rotate, and at the same time, multiple extrusion rollers 611 also rotate, so that the curved surface smoothing processing of the stainless steel belt is completed.
