Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of metal processing, and particularly relates to a protection structure during the rolling process of a plate rolling machine. Background Art
[0002] A plate rolling machine is a device that uses working rolls to bend and form sheet materials. It can form parts with different shapes such as cylindrical parts and conical parts. It is a very important processing device. The working principle of the plate rolling machine is that through the action of external forces such as hydraulic pressure and mechanical force, the working rolls move, so that the sheet material is bent or rolled into shape. According to the rotational movement and position change of working rolls with different shapes, parts such as elliptical parts, arc-shaped parts, and cylindrical parts can be processed.
[0003] Most of the current plate rolling machines only install a limiting device on the feeding side to limit and fix the left and right sides of the workpiece, so as to limit the displacement deformation of the workpiece. Although this method solves the processing displacement deformation of the workpiece caused by the torque force, for a longer workpiece, the unprocessed part will generate a downward gravity due to its own weight. This gravity will form an additional pressure on the processed or being processed part during the processing, resulting in unstable factors during the processing of the sheet material. When not effectively supported, it may act like a lever to generate a prying effect during the processing, causing the processed part to shift or vibrate, thus affecting the processing accuracy of the plate rolling machine and resulting in damages such as scratches, indentations, or even cracks on the surface of the sheet material.
[0004] Therefore, in view of the above current situation, there is an urgent need to develop a protection structure during the rolling process of a plate rolling machine to overcome the deficiencies in current practical applications. Summary of the Invention

Detailed implementation manners
[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be 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 used to limit the present invention.
[0028] The following describes the specific implementation of the present invention in detail in conjunction with specific embodiments.
[0029] As Figures 1-9As shown in the figure, an embodiment of the present invention provides a protective structure for the rolling process of a plate rolling machine, including a chassis 1, a first support plate 2, and a receiving plate 3. The first support plate 2 is fixedly arranged inside the chassis 1. One side of the upper end of the chassis 1 is rotatably connected to the receiving plate 3. A lifting assembly 5 is cooperatively arranged between the chassis 1 and the receiving plate 3. The lifting assembly 5 is used to push the receiving plate 3 against the plate. The lower end of the receiving plate 3 is rotatably connected to a third rotating plate 9. The lower end of the third rotating plate 9 is rotatably connected to a first fixed plate 10. A placement groove 11 is formed on the first support plate 2. An anti-vibration assembly 12 is cooperatively connected inside the placement groove 11. The outer wall of the anti-vibration assembly 12 is fixedly connected to the first fixed plate 10. The anti-vibration assembly 12 restricts the vibration of the receiving plate 3 by cooperating with the third rotating plate 9 and the first fixed plate 10, thereby restricting the vibration of the plate. A fourth support plate 13 is fixedly connected to the first support plate 2. An angle adjustment assembly 14 is rotatably connected to the fourth support plate 13. The angle adjustment assembly 14 is cooperatively connected to the anti-vibration assembly 12. The angle adjustment assembly 14 is used to control the rotation angle range of the anti-vibration assembly 12. The lower end of the first support plate 2 is fixedly connected to a third support plate 6 through a plurality of evenly distributed connecting columns 7. A linkage assembly 8 is cooperatively arranged on the third support plate 6. Two symmetrical clamping assemblies 4 are fixedly arranged on the linkage assembly 8. The linkage assembly 8 is used to control the relative movement of the two clamping assemblies 4. The two clamping assemblies 4 restrict the displacement of the plate by cooperating with each other.
[0030] It can be understood that the protective structure is placed on the feeding side of the plate rolling machine. The receiving plate 3 is used to place the plate. The rotation angle of the receiving plate 3 is less than 90 degrees through the angle adjustment assembly 14.
[0031] In the embodiment of the present invention, the lifting assembly 5 is used to push the receiving plate 3 against the plate. The vibration of the plate is restricted by the cooperation of the anti-vibration assembly 12, the third rotating plate 9, and the first fixed plate 10. The rotation angle range of the anti-vibration assembly 12 is adjusted through the angle adjustment assembly 14, so as to control the rotation angle range of the receiving plate 3, and then more effectively match plates of different materials or thicknesses, prevent the receiving plate 3 from rotating excessively. The relative movement of the two clamping assemblies 4 is controlled through the linkage assembly 8. The displacement of the plate is restricted by the cooperation of the two clamping assemblies 4. It has the effects of adapting to plates of different materials or thicknesses, preventing the receiving plate 3 from rotating excessively, and effectively preventing the plate from vibrating.
[0032] Such as Figure 2 and Figure 3As shown, the lifting assembly 5 includes a first base 51, a first rotating plate 52, a connecting seat 53, a first rotating shaft 54, a first baffle 55 and a second spring 56; two symmetrically distributed connecting seats 53 are connected to the first rotating shaft 54 in a mating manner, both ends of the first rotating shaft 54 are fixedly connected with first baffles 55, second springs 56 are fixedly arranged between the first baffles 55 and the corresponding connecting seats 53, and the second springs 56 are sleeved on the outer wall of the first rotating shaft 54; the first bases 51 are rotatably connected to both the receiving plate 3 and the first support plate 2, and symmetrically distributed first rotating plates 52 are rotatably connected to the first bases 51, and the other ends of the first rotating plates 52 are rotatably connected to the corresponding connecting seats 53.
[0033] During specific application, the two second springs 56 push the two connecting seats 53 to move relatively, and then the connecting seats 53 drive the first rotating plates 52 to rotate relative to the first bases 51 respectively, so as to adjust the distance between the first rotating shaft 54 and the first base 51, and further drive the receiving plate 3 to rotate and lift.
[0034] As Figures 3-7 shown, the anti-shake assembly 12 includes an annular gear 121, an H-shaped inner ring 122, an inner ring gear 123, a second chute 124, a second slider 125, a third spring 126 and a sector-shaped convex head 127; the H-shaped inner ring 122 is fixedly connected to the inner wall of the placement groove 11, the annular gear 121 is rotatably sleeved on the outer wall of the H-shaped inner ring 122, the inner wall of the annular gear 121 is provided with an inner ring gear 123, and the outer wall of the annular gear 121 is fixedly connected to the first fixed plate 10; a second chute 124 is formed in the H-shaped inner ring 122, the second slider 125 is slidably connected to the inner wall of the second chute 124, a third spring 126 is fixedly arranged between the second slider 125 and the bottom end of the inner wall of the second chute 124, the upper end of the second slider 125 is fixedly connected with a sector-shaped convex head 127, and when the receiving plate 3 shakes and descends due to the plate during the ascending process, the sector-shaped convex head 127 engages with the inner ring gear 123.
[0035] Furthermore, a third chute 128 is also formed in the H-shaped inner ring 122, and the third chute 128 communicates with the second chute 124. A fixed cylinder 129 is fixedly connected to the side wall of the second slider 125, a sliding shaft 1210 is slidably connected to the inner wall of the fixed cylinder 129, and a fourth spring 1211 is fixedly arranged between the sliding shaft 1210 and the bottom end of the inner wall of the fixed cylinder 129; a fixed rail plate 1212 is fixedly connected to the side wall of the annular gear 121, a fourth chute 1213 is formed in the fixed rail plate 1212, and one end of the sliding shaft 1210 is slidably connected to the fourth chute 1213.
[0036] Furthermore, the bottom end of the fourth chute 1213 is composed of two angled corners connected end to end.
[0037] It can be understood that the sliding shaft 1210 can only move relative to the fourth sliding groove 1213 in one direction; since the sector-shaped convex head 127 is sector-shaped, the inner ring gear 123 can slide on the curved surface of the sector-shaped convex head 127, but cannot push the flat surface of the sector-shaped convex head 127 to move in the reverse direction; when the sliding shaft 1210, the fixed cylinder 129 and the second slider 125 cooperate to drive the sector-shaped convex head 127 to disengage from the inner ring gear 123, the receiving plate 3 continues to rotate by a certain angle, effectively preventing the large rigid impact that may occur when the plate disengages from the receiving plate 3 from damaging the protective plate or causing safety hazards.
[0038] In specific applications, when the receiving plate 3 rotates and rises, the receiving plate 3 drives the first fixed plate 10 to rotate counterclockwise through the third rotating plate 9, and then the first fixed plate 10 drives the annular gear 121 to rotate. The third spring 126 synchronously pushes the second slider 125 to rise, and then the second slider 125 pushes the sector-shaped convex head 127 to engage with the inner ring gear 123. After that, the inner ring gear 123 pushes the curved surface of the sector-shaped convex head 127 and the second slider 125 to descend, and then the second slider 125 compresses the third spring 126. During this process, when the receiving plate 3 rotates and descends due to the vibration of the plate, the annular gear 121 rotates in the reverse direction, and then the inner ring gear 123 pushes the sector-shaped convex head 127 in the reverse direction. However, since the inner ring gear 123 is stuck to the flat part of the sector-shaped convex head 127 and cannot move, the annular gear 121 controls the third rotating plate 9 and the first fixed plate 10 to be stationary. After that, the third rotating plate 9 controls the receiving plate 3 to be stationary, and then the receiving plate 3 controls the plate to prevent vibration. At this time, the sliding shaft 1210 slides in the upper half of the fourth sliding groove 1213; when the plate disengages from the receiving plate 3, the sliding shaft 1210 enters the lower half of the fourth sliding groove 1213. The sliding shaft 1210 drives the second slider 125 to move downward through the fixed cylinder 129. After that, the second slider 125 drives the sector-shaped convex head 127 to move downward and disengage from the inner ring gear 123. Then, a new plate is placed on the receiving plate 3 again, and the receiving plate 3 rotates and descends under the pressure of the plate.
[0039] Such as Figure 3 , Figure 4 , Figure 5 and Figure 8As shown, the angle adjustment assembly 14 includes a fourth rotating plate 141, a turntable 142, a second sector gear 143, a fifth sliding groove 144, a third slider 145, a fixed shaft 146, a second rotating shaft 147, a third rotating shaft 148, and an electric telescopic rod 149; a turntable 142 is rotatably connected to the placement groove 11, the outer wall of the turntable 142 is fixedly connected with a second sector gear 143, a fifth sliding groove 144 is formed in the turntable 142, a fixed shaft 146 is fixedly connected to the inner wall of the fifth sliding groove 144, a third slider 145 is slidably sleeved on the outer wall of the fixed shaft 146, one end of the third slider 145 is rotatably connected to a fourth rotating plate 141, and the other end of the fourth rotating plate 141 is rotatably connected to the lower end of the receiving plate 3; the side wall of the third slider 145 is rotatably connected to a third rotating shaft 148, the other end of the third rotating shaft 148 is rotatably connected to a second rotating shaft 147, and the other end of the second rotating shaft 147 is rotatably connected to the inner wall of the fifth sliding groove 144; an electric telescopic rod 149 is also rotatably connected to the inner wall of the fifth sliding groove 144, and the other end of the electric telescopic rod 149 is rotatably connected to the second rotating shaft 147.
[0040] During specific application, when the receiving plate 3 rotates and rises, the receiving plate 3 drives the fourth rotating plate 141 to move, then the fourth rotating plate 141 drives the turntable 142 to rotate through the third slider 145, and then the turntable 142 drives the second sector gear 143 to rotate until the second sector gear 143 engages with the outer wall of the annular gear 121 to restrict the movement of the annular gear 121. In addition, control the electric telescopic rod 149 to extend or contract, then the electric telescopic rod 149 drives the second rotating shaft 147 to rotate, and then the second rotating shaft 147 drives the third slider 145 to slide along the fixed shaft 146 through the third rotating shaft 148, so as to adjust the rotation angle range of the turntable 142 corresponding to the rotation angle range of the receiving plate 3, and further adjust the rotation angle range of the annular gear 121, which can effectively prevent the lifting assembly 5 from driving the receiving plate 3 to perform excessive useless rotation, thus wasting time.
[0041] As Figure 1 、 Figure 3 and Figure 9 shown, the linkage assembly 8 includes a first rack 81, a second rack 82, a first sector gear 83, a second rotating plate 84, a first sliding plate 85, and a rectangular fixed plate 86; a first rack 81 is slidably connected to the third support plate 6, and the first rack 81 is meshed with the annular gear 121, and symmetrically distributed second racks 82 are fixedly connected to both sides of the first rack 81; a plurality of uniformly distributed first sector gears 83 are rotatably connected to the third support plate 6, and the first sector gears 83 are meshed with the second racks 82; a plurality of uniformly distributed rectangular fixed plates 86 are fixedly connected to the lower end surface of the first support plate 2, the inner walls of the rectangular fixed plates 86 are all slidably connected with a first sliding plate 85, one end of the first sliding plate 85 is rotatably connected to a second rotating plate 84, and the other end of the second rotating plate 84 is rotatably connected to the upper end surface of the first sector gear 83.
[0042] In specific applications, when the receiving plate 3 initially rotates and rises, the annular gear teeth 121 drive the first rack 81 to move. The first rack 81 drives the first sector gear 83 to rotate clockwise through the second rack 82. Then, the first sector gear 83 drives the first slide plate 85 to slide inward along the inner wall of the circular fixed plate 86 through the second rotating plate 84 until the last tooth of the first sector gear 83 disengages from the second rack 82. After that, the first slide plate 85 remains stationary. When the receiving plate 3 rotates and descends, the annular gear teeth 121 drive the first slide plate 85 to slide outward along the inner wall of the circular fixed plate 86 through the first rack 81, the first sector gear 83, and the second rotating plate 84.
[0043] As Figure 1 and Figure 2 shown, the clamping assembly 4 includes a second support plate 41, a first chute 42, a first slider 43, a sector plate 44, a circular arc plate 45, an arc-shaped slide plate 46, a clamping plate 47, and a first spring 48. Second support plates 41 are fixedly connected to both sides of the first slide plates 85 on both sides of the third support plate 6. The second support plate 41 is provided with a first chute 42. A sector plate 44 is also rotatably connected to the second support plate 41. One end of the sector plate 44 is fixedly connected to a first slider 43, and the first slider 43 is slidably connected to the inner wall of the first chute 42. The other end of the sector plate 44 is fixedly connected to a circular arc plate 45. The inner wall of the circular arc plate 45 is slidably connected to an arc-shaped slide plate 46. One end of the arc-shaped slide plate 46 is fixedly connected to a clamping plate 47. A plurality of uniformly distributed first springs 48 are fixedly arranged between the sector plate 44 and the clamping plate 47.
[0044] It can be understood that the sector plate 44 is collinear with the rotation axis of the receiving plate 3.
[0045] In specific applications, when the first slide plate 85 slides inward along the inner wall of the circular fixed plate 86, the first slide plate 85 drives the sector plate 44 to move inward through the second support plate 41. Then, the sector plate 44 drives the circular arc plate 45 to move inward. After that, the circular arc plate 45 drives the clamping plate 47 to move inward to squeeze the plate material, so that the plate material is located in the middle and does not deviate. The receiving plate 3 synchronously drives the sector plate 44 to rotate through the circular arc plate 45. Then, the sector plate 44 drives the first slider 43 to slide in the first chute 42. When the first slide plate 85 slides outward along the inner wall of the circular fixed plate 86, the first slide plate 85 drives the sector plate 44 to move outward through the second support plate 41. Then, the sector plate 44 drives the circular arc plate 45 to move outward. The receiving plate 3 synchronously drives the sector plate 44 to rotate through the circular arc plate 45. Then, the sector plate 44 drives the first slider 43 to slide back to its original position in the first chute 42.
[0046] The working principle of the present invention is as follows: Two second springs 56 push two connecting seats 53 to approach each other. Then, the connecting seats 53 drive the first rotating plates 52 to rotate relative to the first base 51 respectively, so as to increase the distance between the first rotating shaft 54 and the first base 51, and further drive the receiving plate 3 to rotate and rise. The receiving plate 3 synchronously drives the first fixed plate 10 to rotate counterclockwise through the third rotating plate 9. Then, the first fixed plate 10 drives the annular gear 121 to rotate. The third spring 126 synchronously pushes the second slider 125 to rise. Then, the second slider 125 pushes the sector-shaped convex head 127 to engage into the inner ring gear 123. After that, the inner ring gear 123 pushes the curved surface of the sector-shaped convex head 127 and the second slider 125 to descend. Then, the second slider 125 compresses the third spring 126. During this process, when the receiving plate 3 rotates and descends due to the vibration of the plate, the annular gear 121 rotates in the reverse direction. Then, the inner ring gear 123 pushes the sector-shaped convex head 127 in the reverse direction. However, since the inner ring gear 123 is engaged with the flat part of the sector-shaped convex head 127 and cannot move, the annular gear 121 controls the third rotating plate 9 and the first fixed plate 10 to be stationary. After that, the third rotating plate 9 controls the receiving plate 3 to be stationary. Then, the receiving plate 3 controls the plate to descend without vibration, so as to prevent the plate from vibrating. At this time, the sliding shaft 1210 slides in the upper half of the fourth sliding groove 1213. During this process, the annular gear 121 drives the first rack 81 to move. The first rack 81 drives the first sector gear 83 to rotate clockwise through the second rack 82. Then, the first sector gear 83 drives the first sliding plate 85 to slide inward along the inner wall of the loop-shaped fixed plate 86 through the second rotating plate 84. The first sliding plate 85 drives the sector plate 44 to move inward through the second support plate 41. Then, the sector plate 44 drives the loop-shaped arc plate 45 to move inward. After that, the loop-shaped arc plate 45 drives the clamping plate 47 to move inward to squeeze the plate, so that the plate is located in the middle and does not deviate until the last tooth of the first sector gear 83 disengages from the second rack 82. After that, the first sliding plate 85 is in a stationary state. The receiving plate 3 synchronously drives the sector plate 44 to rotate through the loop-shaped arc plate 45. Then, the sector plate 44 drives the first slider 43 to slide in the first sliding groove 42. When the plate detaches from the receiving plate 3, the sliding shaft 1210 enters the lower half of the fourth sliding groove 1213. The sliding shaft 1210 drives the second slider 125 to move downward through the fixed cylinder 129. After that, the second slider 125 drives the sector-shaped convex head 127 to move downward to disengage from the inner ring gear 123. Then, a new plate is placed on the receiving plate 3 again. The receiving plate 3 rotates and descends under the pressure of the plate. The annular gear 121 drives the first sliding plate 85 to slide outward along the inner wall of the loop-shaped fixed plate 86 through the first rack 81, the first sector gear 83 and the second rotating plate 84.In addition, when the receiving plate 3 rotates and rises, the receiving plate 3 drives the fourth rotating plate 141 to move. Then, the fourth rotating plate 141 drives the rotating disk 142 to rotate through the third slider 145. Subsequently, the rotating disk 142 drives the second sector gear 143 to rotate until the second sector gear 143 engages with the outer wall of the annular gear 121 to restrict the movement of the annular gear 121. Control the electric telescopic rod 149 to extend or contract. Then, the electric telescopic rod 149 drives the second rotating shaft 147 to rotate. After that, the second rotating shaft 147 drives the third slider 145 to slide along the fixed shaft 146 through the third rotating shaft 148, so as to adjust the rotation angle range of the rotating disk 142 corresponding to the rotation angle range of the receiving plate 3, and further adjust the rotation angle range of the annular gear 121, which can effectively prevent the lifting component 5 from driving the receiving plate 3 to perform excessive useless rotation, thereby wasting time.
[0047] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
