Description

Technical Field

[0001] The utility model relates to the technical field of ship processing, in particular to a plate rolling device for processing ship steel structures. Background Art

[0002] In the field of shipbuilding steel structure processing, traditional plate rolling devices often face technical challenges when dealing with complex and changing processing requirements. These challenges mainly focus on adaptability to workpieces of varying thicknesses and flexibility in contact and squeeze roller positioning.

[0003] Traditional plate rolling devices are often designed to process workpieces within a specific thickness range or diameter. The position of the contact extrusion roller is often fixed, making it difficult to adjust according to the specific requirements of the workpiece. This design is particularly inconvenient when processing diverse, non-standardized ship steel structure components. When workpieces of varying thicknesses need to be processed, the non-adjustable position of the contact extrusion roller may result in unsatisfactory processing results, such as uneven plate deformation and reduced surface quality. At the same time, when rolling plates of varying diameters is required, traditional fixed-position extrusion rollers are even more difficult to meet the requirements, limiting processing flexibility and precision.

DETAILED DESCRIPTION

[0029] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] See also Figure 1 and Figure 8 As shown, a plate rolling device for processing ship steel structures includes a casing 1, a first squeezing roller 2 arranged on the casing 1 for squeezing a workpiece, a first hydraulic cylinder 3 installed on the casing 1 for driving the squeezing roller to descend in the vertical direction, and a pair of contact and clamping rollers 4 arranged on the casing 1 and located below the first squeezing roller 2, and a driving limiting mechanism 5 for driving the contact and clamping rollers 4 to move relatively away from or closer to each other in a horizontal straight line direction. The driving limiting mechanism 5 includes a sliding plate 51, a limiting rod 52 and a connecting rod supporting mechanism 6 for driving the sliding plate 51 to slide in the vertical direction. The plate rolling device for processing ship steel structures also includes a loading and cleaning mechanism 7 arranged on the casing 1 for loading and unloading the workpiece. The limiting rod 52 is clearance-matched with the sliding plate 51, and the limiting rod 52 is used to limit the sliding plate 51 from stably rising or falling in the vertical direction.

[0031] When it is necessary to extrude and roll the workpiece, the workpiece is first placed on the loading and cleaning mechanism 7, and then the workpiece can be moved between the first squeezing roller 2 and a pair of contact and clamping rollers 4 through the loading and cleaning mechanism 7. At this time, the first hydraulic cylinder 3 is started, driving the first squeezing roller 2 to descend in the vertical direction until the first squeezing roller 2 contacts the workpiece and presses the workpiece against the contact and clamping roller 4. Then the first squeezing roller 2 rotates. When it is necessary to roll the workpiece into different diameters, the sliding plate 51 is driven by the connecting rod supporting mechanism 6 to rise or fall vertically along the limiting rod 52. At this time, the pair of contact and clamping rollers 4 move away from each other, and the gap between the first squeezing roller 2 and the contact and clamping roller 4 is changed. At this time, workpieces of different thicknesses can be processed into cylinders of different diameters, thereby improving the applicability of the device.

[0032] See also Figure 3 and Figure 5 As shown, the drive limiting mechanism 5 also includes a supporting plate 53, a horizontal straight groove 54 and a guide inclined groove 55; the supporting plate 53 is arranged on the sliding plate 51, and the supporting plate 53 is a frame-shaped slotted shape, and the opening of the supporting plate 53 faces one side of the housing 1; the horizontal straight groove 54 is opened on the supporting plate 53, and the contact and clamping roller 4 is located in the horizontal straight groove 54 and slides in the horizontal straight direction; the guide inclined groove 55 is opened on the housing 1, and the opening of the guide inclined groove 55 faces the side close to the sliding plate 51, and the guide inclined groove 55 is used to limit the sliding of the contact and clamping roller 4.

[0033] When the sliding plate 51 rises in the vertical direction, the sliding plate 51 can slide stably along the limiting rod 52 during this process, and at this time the contact and clamping roller 4 can move relatively away from each other along the horizontal straight groove 54 matched with the groove and the guide inclined groove 55 opened on the casing 1, so as to adjust the position of a pair of contact and clamping rollers 4, which can adapt to workpieces of different thicknesses and different diameters.

[0034] See also Figure 3 and Figure 5 As shown, the connecting rod supporting mechanism 6 includes a first rotary driver 61, a bidirectional threaded rod 62, a sliding block 63 and a connecting rod 64; the first rotary driver 61 is arranged on the housing 1 and is located below the first extrusion roller 2; the input end of the bidirectional threaded rod 62 is arranged at the output end of the first rotary driver 61 through a coupling; the sliding block 63 is arranged on the bidirectional threaded rod 62 in a horizontal linear sliding direction and has a pair; the connecting rod 64 is rotatably arranged on the sliding plate 51 and the sliding block 63 respectively.

[0035] When the sliding plate 51 needs to be raised or lowered in the vertical direction, the first rotary driver 61 is started first, which can drive the bidirectional threaded rod 62 to rotate. When the bidirectional threaded rod 62 rotates, it can drive a pair of sliding blocks 63 threadedly connected thereto to move relatively away from each other. During the sliding process of the sliding block 63, the connecting rod 64 can be driven to lift the rotating sliding plate 51, thereby achieving the vertical sliding of the sliding plate 51 and realizing the lifting function of the sliding plate 51.

[0036] See also Figure 5 and Figure 6 As shown, the connecting rod supporting mechanism 6 also includes a protective frame 65 and a through slot 66; the protective frame 65 is arranged on the housing 1 and is located above the first rotary driver 61; the through slot 66 is opened on the protective frame 65 and has a pair of through slots 66, which are clearance-matched with the connecting rod 64, and the through slot 66 is used for the connecting rod 64 to move.

[0037] When the connecting rod 64 swings at an inclined angle and causes the sliding plate 51 to rise, the connecting rod 64 can swing stably along the groove 66 opened on the protective frame 65, thereby improving the swinging stability of the connecting rod 64 and avoiding the connecting rod 64 from being offset when lifting and sliding the sliding plate 51.

[0038] See also Figure 6 and Figure 7 As shown, the feeding and cleaning mechanism 7 includes a feeding frame 71, an auxiliary electric roller 72, a cleaning frame 73 and a cleaning plate 74; the feeding frame 71 is rotatably set on the casing 1 and has a pair; the auxiliary electric roller 72 is set on the feeding frame 71 and has a plurality of auxiliary electric rollers, and the auxiliary electric roller 72 is used to stably feed the workpiece between the first squeezing roller 2 and the contact and pressing roller 4; the cleaning frame 73 is set on the feeding frame 71 and is located above the auxiliary electric roller 72; the cleaning plate 74 is vertically slidably set on the cleaning frame 73 and is located above the auxiliary electric roller 72.

[0039] When it is necessary to clean the dust and impurities on the outside of the workpiece on the loading rack 71, the workpiece is first placed on several auxiliary electric rollers 72, and then the auxiliary electric rollers 72 drive the workpiece to slide in the horizontal straight direction. During this process, the transported workpiece can contact the cleaning plate 74. The cleaning plate 74 is made of flexible material. The cleaning plate 74 can clean the dust or impurities attached to the outer wall of the workpiece to avoid dust and impurities on the workpiece during the later processing process, which may affect the rolling effect of the workpiece.

[0040] See also Figure 6 and Figure 7As shown, the feeding and cleaning mechanism 7 also includes a second rotary driver 75, a rotary rod 76, a connecting block 77 and a vertical rod 78; the second rotary driver 75 is arranged on the cleaning frame 73; the input end of the rotary rod 76 is installed on the output end of the second rotary driver 75 through a coupling; the connecting block 77 is arranged on the cleaning plate 74, and the connecting block 77 is threadedly connected to the rotary rod 76; the vertical rod 78 is arranged on the cleaning frame 73, and the vertical rod 78 is gap-fitted with the cleaning block, and the vertical rod 78 is used to limit the vertical rise or fall of the cleaning block, and a laser thickness sensor 711 for detecting the thickness of the workpiece is provided on the casing 1, and the sensor sends the detected signal to the controller 11. The housing 1 is also provided with a controller 11 connected to the laser thickness measuring sensor 711. The controller 11 receives the signal sent by the laser thickness measuring sensor 711 and controls the start and stop of the second rotation driver 75 according to the signal content. The housing 1 is also provided with a position feedback sensor 712 for detecting the accurate contact between the cleaning plate 74 and the workpiece. The position feedback sensor 712 is connected to the controller 11. The position feedback sensor 712 is used to transmit the signal of the contact state and non-contact state of the cleaning plate 74 and the workpiece to the controller 11.

[0041] When it is necessary to clean the workpiece on the auxiliary electric roller 72, the laser thickness sensor 711 first detects the thickness of the workpiece, and then sends a signal to the controller 11. After receiving the signal, the controller 11 can control the second rotary driver 75 to rotate. When the second rotary driver 75 is started, it drives the rotating rod 76 to vertically rise or fall the threaded connecting block 77 until the connecting block 77 drives the cleaning plate 74 to contact the surface of the workpiece. The position feedback sensor 712 sends a signal to the controller 11, and the controller 11 can stop starting the second rotary driver 75, thereby realizing automatic adaptive adjustment and cleaning of workpieces of different thicknesses, so as to fine-tune the position of the cleaning plate 74 to ensure the best cleaning effect.
