[0032] Reference Figure 1-Figure 8A tube and shell pressure vessel plate rolling machine comprises a symmetrically arranged frame 1, a driving roller 2 is arranged between two frames 1, a limit roller 3 is arranged above the driving roller 2, and an adjustable adjustment component 4 is arranged on one side of the driving roller 2 and the limit roller 3 on the two frames 1, which is used to adjust the bending angle of the tube plate; a jet component 5 is arranged on one side of one of the frames 1, and the jet component 5 is driven to reciprocate when the driving roller 2 rotates, and is used to blow air on the surface of the workpiece when the adjustment component 4 is bent; a lubrication component 6 is arranged on the jet component 5, one end of which is connected to the adjustment component 4, and is used to automatically convey lubrication to the adjustment component 4. The transmission roller 2 includes a reduction motor 21 fixed at one end of the transmission roller 2, and the reduction motor 21 is installed on a side surface of another frame 1. A main rotating gear 22 is fixed to the other end of the transmission roller 2, and a sub-rotating gear 23 is meshed on the surface of the main rotating gear 22. The sub-rotating gear 23 is installed at one end of the limiting roller 3. The limiting roller 3 includes a second slider 31 fixed at both ends of the limiting roller 3, and the second slider 31 is slidably connected in the second slide groove 32. The second slide groove 32 is opened on the surface of the frame 1, and the top of the second slider 31 is rotatably connected to a screw 33 through a bearing, and the screw 33 is threadedly connected to the frame 1.

[0033] In this embodiment, when in use, the workpiece is placed in advance in the gap between the driving roller 2 and the limiting roller 3, and the distance between the limiting roller 3 and the driving roller 2 is adjusted according to the thickness of the plate. The driving roller 2 is driven by the power source to rotate, and the plate to be processed can be transported and passed through the limiting of the adjusting component 4 to achieve the bending and deformation processing of the plate, so as to obtain the required bent plate workpiece. However, in the prior art, some plate rolling machine equipment requires manual adjustment to control the bending angle of the plate when processing the plate, which is cumbersome to operate and use, and has low efficiency. In addition, under frequent maintenance, the processing accuracy is poor, which affects the output quality of the workpiece. Therefore, in the invention, the adjusting component 4 is set to automatically adjust the height of the adjusting roller 44 according to the state of the plate and the required process, thereby achieving the desired bending deformation of the plate. The control of the material bending processing angle is more convenient and quick to operate, the error caused by manual adjustment is reduced, and the accuracy of the device operation is improved. During the operation of the device, the transmission roller 2 rotates to drive the set jet component 5 to run synchronously, so that the jet component 5 generates a cooling airflow, which is then automatically transported to the adjusting roller 44 at the adjusting component 4, and the bending part of the workpiece is blown to cool and cool down, thereby accelerating the shaping of the workpiece, improving the stability of the state of the workpiece after bending processing, and ensuring the product quality. At the same time, with the setting of the lubrication component 6, the required lubricating oil is automatically transported to the adjusting component 4, and the surface of the adjusting roller 44 is evenly coated, thereby reducing the wear on the adjusting component 4, extending the service life of the adjusting component 4, avoiding frequent maintenance, resulting in poor adjustment accuracy of the adjusting component 4, and saving maintenance costs.

[0034] In a preferred embodiment, referring to Figure 3 and Figure 4 The adjusting assembly 4 includes a driving part 41 fixed on the frame 1, the output end of the driving part 41 is connected to a first slider 42, the first slider 42 is slidably connected in a first slide groove 43, the first slide groove 43 is provided on the surface of the frame 1, an adjusting roller 44 is installed on the first slider 42 through a bearing, a cavity 45 is provided inside the adjusting roller 44, an oil delivery hole 46 is provided on the inner wall of the adjusting roller 44, and symmetrically distributed arc pieces 47 are installed on the inner wall of the oil delivery hole 46, and a protective net 48 is provided on the outer wall of the adjusting roller 44 at one end of the oil delivery hole 46.

[0035] In this solution, the driving part 41 adopts an electric push rod instead of a driving operation. When the height of the adjusting roller 44 needs to be adjusted, the driving part 41 is started to drive the first slider 42 to move, thereby driving the adjusting roller 44 to run synchronously. When the position of the adjusting roller 44 is adjusted, the plate after the transmission roller 2 and the limiting roller 3 pass through is limited to different degrees according to the position of the adjusting roller 44, and then raised and bent, thereby achieving different degrees of bending processing of the plate. The first slider 42 slides inside the first slide groove 43, which can move and limit the adjusting roller 44, thereby improving the structure. In order to improve the stability of the workpiece, this solution is adopted to replace manual operation, which is more convenient and quick, and saves the time of manual shutdown operation and adjustment, so that the device is more efficient when processing workpieces. The setting of the cavity 45 facilitates the subsequent delivery of lubricating oil in the lubricating component 6, and then discharges it through the oil delivery hole 46. An arc-shaped sheet 47 is provided inside the oil delivery hole 46 to make the lubricating oil flow out slowly and reduce the amount of lubricating oil discharged. The setting of the protective net 48 prevents debris and foreign matter on the workpiece from entering the interior of the oil delivery hole 46, plays an isolation and protection effect, and keeps the lubricating oil discharged smoothly.

[0036] In a preferred embodiment, referring to Figure 5 and Figure 7The jet assembly 5 includes a synchronous belt 51 located on one side of the adjusting roller 44, the synchronous belt 51 is sleeved on the surface of the driving roller 2, the end of the synchronous belt 51 is drivingly connected with a rotating shaft 52, one end of the rotating shaft 52 is rotatably connected to the frame 1 through a bearing, a cam 53 is fixed on the surface of the rotating shaft 52, one end of the cam 53 is fitted with a reciprocating member, the reciprocating member includes a limit plate 54 fitted on the end of the cam 53, a lifting rod 55 is fixed to the bottom of the limit plate 54, a piston 56 is fixed to the end of the lifting rod 55, the piston 56 is slidably connected in a connecting cylinder 57, and the connecting cylinder 57 is installed in one of the frames 1, an extrusion spring 58 is fixed between the limit plate 54 and the connecting tube 57, the extrusion spring 58 is sleeved on the surface of the lifting rod 55, an air inlet pipe 59 is arranged on one side of the top of the connecting tube 57, and an air delivery pipe 591 is arranged on the other side of the air inlet pipe 59 at the top of the connecting tube 57, and one end of the air delivery pipe 591 is connected to a blowing member, and the blowing member includes an air jet pipe 592 fixed to one end of the air delivery pipe 591, and the surface of the air jet pipe 592 is installed with air jet heads distributed at equal intervals, and the end of the air jet pipe 592 is installed with a fixing block 593, and the fixing block 593 is installed on the first sliding block 42.

[0037] By adopting the above scheme, when one end of the transmission roller 2 is driven to rotate by the reduction motor 21, the rotating shaft 52 is driven to rotate synchronously by the synchronous belt 51. The rotation of the rotating shaft 52 causes the piston 56 to slide up and down inside the connecting tube 57. Since the piston 56 divides the connecting tube 57 into two chambers, one of which is a rod chamber. With the reciprocating motion of the piston 56, the external airflow is sucked into the rod chamber through the air inlet pipe 59, and then transported to the injection pipe 592 through the air delivery pipe 591, and ejected through the nozzle on the surface of the injection pipe 592. With the ejection of the cooling airflow, the surface of the workpiece after bending at the adjusting component 4 can be blown to cool and reduce the temperature. This can accelerate the stable state of the workpiece after bending, avoid the situation that some thinner plates are heated after bending due to being too long and deformed, and the state after bending is unstable and the angle after bending changes, thereby further improving the accuracy of the processing operation of the device. When blowing, the adjusting roller 44 can also be blown and cleaned to avoid foreign matter accumulating on the surface of the adjusting roller 44, eliminating the trouble of manual cleaning and maintenance.

[0038] It should be noted that a one-way valve is provided at the connection between the air inlet pipe 59 , the air delivery pipe 591 and the connecting tube 57 .

[0040] By adopting the above scheme, when the piston 56 reciprocates up and down, the rodless cavity part in the connecting cylinder 57 draws lubricating oil from the oil storage tank 62 through the adsorption force generated by the rising of the piston 56, and then transports it to the inside of the adjusting roller 44 through the oil pipe 64, wherein a one-way valve is provided at the connection between the connecting pipe 61 and the oil pipe 64 and the connecting cylinder 57, so as to maintain the smooth operation of the structure, so that the device can automatically draw lubricating oil to evenly coat the adjusting roller 44 during operation, reduce the wear of the adjusting roller 44 caused by long-term use, and at the same time, further improve the accuracy of the bending adjustment of the adjusting component 4, and extend the service life of the adjusting roller 44, avoid the installation error caused by frequent replacement of the adjusting roller 44, and cause inaccurate adjustment values.
