Description

Technical Field

[0001] The invention belongs to the technical field of plate rolling machines, and in particular relates to a four-roller CNC plate rolling machine. Background Art

[0002] Plate rolling machines are versatile devices used to bend metal sheets into cylindrical, curved, or other shaped workpieces. Based on the three-point circular motion principle, they utilize the relative position and rotation of the work rollers to plastically deform and bend the sheet, thus achieving the desired result. Plate rolling machines are widely used in various industries, including boilers, shipbuilding, petroleum, chemical engineering, hydraulic engineering, metal structures, and other machinery manufacturing. A four-roller CNC plate rolling machine is a variant of this type of machine. It consists of four rollers—two upper and two lower—designed to provide greater stability and precision.

[0003] Traditional four-roller plate rolling machines are primarily designed to maximize sheet rolling accuracy and mechanical performance, with less consideration given to the cleanliness of the feed sheet surface. During the rolling process, impurities such as scale, rust, and dirt from the sheet surface easily adhere to the feed plate. First, these impurities are difficult to remove, creating additional friction between the sheet and the rollers, leading to uneven sheet deformation and even scratches. Second, adherence increases roller wear, shortening the equipment's lifespan. This wear reduces roller precision and surface quality, further impacting subsequent rolling operations. Summary of the Invention

[0004] The purpose of the present invention is to provide a four-roller CNC plate rolling machine for existing devices to solve the problems raised in the above background technology.

The rear end of the first connecting piece is fixedly connected to the scraper;

[0009] The first bevel gear is meshed and connected to a second bevel gear below. A second gear is adhesively bonded to the lower side of the second bevel gear. A plurality of the second gears are also meshed and driven on both sides of the second gear. A cleaning brush is adhesively bonded to the lower side of each second gear. A seventh central shaft is commonly passed through the center of each group of the second bevel gear and the second gear. A second connecting piece is fixedly connected to the upper end of the seventh central shaft. The rear end of the second connecting piece is fixedly connected to the scraper. A connecting piece is commonly passed through the center of each group of the second gear and the cleaning brush. The connecting piece is formed by fixedly connecting a central shaft below and a connecting plate above. The other end of the upper connecting plate is fixedly connected to the scraper.

[0010] The present invention further illustrates that a to-be-rolled sheet is placed above the transmission component and the dust removal component.

[0011] The present invention further describes that the transmission component includes a first central shaft passing through the two side plates, a first shaft roller is sleeved on the first central shaft between the two side plates, a second central shaft is also passed through the two side plates behind the first central shaft, a second shaft roller is sleeved on the second central shaft between the two side plates, one end of the first central shaft passes through one of the side plates and is connected to a coupling, the other end of the coupling is connected to an electric motor, the motor is fixedly mounted in a motor frame, and the motor frame is fixedly mounted on the side plates.

[0012] The present invention further describes that the dust removal assembly includes a third central shaft passed through the two side panels, a first transmission roller is sleeved on the third central shaft, a hard wear-resistant brush is glued to the outer side of the first transmission roller, and a fourth central shaft is passed through the two side panels behind the third central shaft, a second transmission roller is sleeved on the fourth central shaft, a soft adsorption brush is glued to the outer side of the second transmission roller, and the third central shaft and the fourth central shaft are both located between the first central shaft and the second central shaft.

[0013] The present invention further describes that the shock zone includes four seismic belt parts, namely the first seismic belt, the second seismic belt, the third seismic belt and the fourth seismic belt. The four seismic belt parts are evenly distributed from top to bottom, and the fluctuation decreases successively.

[0014] The present invention further describes that a front support plate is fixedly installed in front of the side plate.

[0015] The present invention further describes that a four-roller mechanism is further provided on the support behind the scraper, one end of the four-roller mechanism is connected to a driving mechanism, and the other end of the four-roller mechanism is connected to an adjusting mechanism.

[0016] The present invention further illustrates the method for cleaning a plate by a four-roll CNC plate rolling machine, characterized in that: the plate to be rolled is placed on the transmission component and the dust removal component, the transmission component transmits the plate to be rolled backward, the plate to be rolled passes through the limit plate backward, when there is dirt on the plate to be rolled, the dirt will press against the front side of the ramp slide and push the ramp slide backward, and at the same time, the first spring is stretched, and the ramp slide contacts the roller during the backward movement, the roller rolls with the fifth central axis as the axis to adapt to the relative displacement between the roller and the ramp slide, the roller rolls onto the vibration zone, and due to the connection effect of the fifth central axis, the vibration block moves upward with the fifth central axis, and the second spring is shortened;

[0017] Meanwhile, the vibration block drives the connecting rod to move upward. Since the roller rolls onto the oscillation area, while the connecting rod moves upward, it continuously jitters up and down. The elastic connecting rod drives the limiting block to jitter. At the same time, due to the connection of the elastic strip, all the limiting blocks jitter, causing the knocking rod to drive the knocking hammer to repeatedly knock the sheet to be coiled up and down, knocking off the dirt on the sheet to be coiled. When the dirt is more firmly attached, the slope slider is pushed further backward. The more violently the roller bumps on the oscillation area, the more violently the limiting block jitters, so that the knocking rod drives the knocking hammer to exert a greater knocking force on the sheet to be coiled, accelerating the cleaning effect of the dirt on the sheet to be coiled. At the same time, the dust removal component cleans the dirt on the back side of the sheet to be coiled.

[0018] Compared with the prior art, the beneficial effects achieved by the present invention are: In the present invention,

[0019] (1) By arranging to place the sheet to be coiled on the transmission component and the dust removal component, the transmission component transports the sheet to be coiled backward. The dirt on the sheet to be coiled will abut against the front side of the slope slider and push the slope slider backward. During the backward movement of the slope slider, it contacts the roller. The roller rotates with the fifth central axis as the center. The roller rolls onto the oscillation area, and the vibration block moves upward with the fifth central axis. The vibration block drives the connecting rod to move upward. Since the roller rolls onto the oscillation area, while the connecting rod moves upward, it continuously jitters up and down. The elastic connecting rod drives the limiting block to jitter. At the same time, due to the connection of the elastic strip, all the limiting blocks jitter, causing the knocking rod to drive the knocking hammer to repeatedly knock the sheet to be coiled up and down to knock off the dirt and clean the dirt on the sheet.

[0020] (2) By arranging that while the limiting block jitters up and down, it drives the rack to repeatedly move up and down. The rack repeatedly moves up and down to engage the first gear to rotate forward and backward repeatedly. The first gear drives the first bevel gear to rotate forward and backward repeatedly with the sixth central axis as the center. While the first bevel gear rotates, it engages the second bevel gear to rotate. While the second bevel gear rotates, it drives the second gear and the cleaning brush to rotate with the seventh central axis as the center. At the same time, the first rotating second gear drives the other second gears to drive the cleaning brushes below to rotate through meshing transmission. The rotation of the cleaning brush can brush the surface of the sheet, which is used for the auxiliary cleaning of the dirt on the sheet.

[0021] (3) By providing the dust removal assembly, during the backward transmission of the sheet to be wound, it successively contacts and drives with the hard wear-resistant brush and the soft adsorption brush, causing the first transmission roller to drive the hard wear-resistant brush to rotate around the third central axis, and the second transmission roller to drive the soft adsorption brush to rotate around the fourth central axis, so as to clean the dirt on the back side of the sheet to be wound.

[0031] The technical solution of the present invention will be further described in detail below in conjunction with the preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Refer to Figures 1 to 7 , the embodiment of the present invention provides a four-roller numerical control plate rolling machine, as shown in Figure 1 and Figure 3 shown, the four-roller numerical control plate rolling machine includes a support 6, a transmission mechanism 1 is fixedly installed on the support 6, the transmission mechanism 1 includes two opposite side plates 11, and a transmission component 12 and a dust removal component 13 are installed between the two side plates 11. A limiting plate 14 is jointly installed on the two side plates 11, one side of the limiting plate 14 is fixedly connected with a first spring 15, it is set that the limiting plate 14 is in front of the first spring 15, the other end of the first spring 15 is fixedly connected with a slope slider 16, an oscillation area 17 is arranged on the slope of the slope slider 16, and oscillation components 18 are fixedly installed on the two side plates 11 at the rear of the slope slider 16.

[0033] The transmission component 12 is used for the transmission of the board, and the dust removal component 13 is used for cleaning the dirt on the surface of the board. The limiting plate 14 is fixed to the front end of the side plate 11, and is connected to the ramp slider 16 through the first spring 15 to form an elastic sliding structure. When the dirt abuts against the front side of the ramp slider 16, the ramp slider 16 is simultaneously pushed to move backward, and the first spring 15 stretches.

[0034] As Figure 3 and Figure 4 As shown, each of the oscillation components 18 includes a rectangular frame 181. A second spring 182 is provided at the upper end of the inner frame of the rectangular frame 181. A vibration block 183 is provided at the lower end of the second spring 182. A fifth central axis 1831 is commonly passed through between the two vibration blocks 183, and a roller 1832 is sleeved on the fifth central axis 1831. A rubber pad 184 is adhesively bonded to the lower end of the inner frame of the rectangular frame 181. A connecting rod 185 is further provided above the vibration block 183. The connecting rod 185 passes upward through the rectangular frame 181 and is connected to a connecting block 186. An elastic connecting rod 19 is connected to the rear side of the connecting block 186, and the rear end of the elastic connecting rod 19 is connected to a cleaning mechanism 2.

[0035] During the backward movement of the ramp slider 16, it contacts the roller 1832. The roller 1832 rolls around the fifth central axis 1831 to adapt to the relative displacement with the ramp slider 16. When the roller 1832 rolls onto the oscillation area 17, due to the connection of the fifth central axis 1831, the vibration block 183 moves upward along with the fifth central axis 1831, and the second spring 182 shortens. At the same time, the vibration block 183 drives the connecting rod 185 to move upward. Since the roller 1832 rolls onto the oscillation area 17, while the connecting rod 185 moves upward, it continuously jitters up and down, and drives the cleaning mechanism 2 to jitter up and down through the elastic connecting rod 19. Since the elastic connecting rod 19 has elasticity, when the elastic connecting rod 19 drives one end to move upward, the elastic connecting rod 19 undergoes elastic deformation, and the other end of the elastic connecting rod 19 does not rise accordingly. At the same time, it is ensured that when the ramp slider 16 moves backward to the farthest position, it does not collide with the cleaning mechanism 2. The rubber pad 184 is used to absorb the impact energy when the vibration block 183 descends to prevent rigid collision.

[0036] As Figure 4As shown, the cleaning mechanism 2 includes a plurality of limit blocks 21 connected to the elastic connecting rod 19, and the limit blocks 21 are arranged in a row. An elastic strip 211 is connected between every two limit blocks 21. Except for the limit blocks 21 at the two ends, a knocking rod 22 is passed through the center of each limit block 21, and each knocking rod 22 is connected to a blocking cover 231. A third spring 23 is sleeved on each knocking rod 22 between the limit block 21 and the blocking cover 231, and a knocking hammer 24 is fixedly connected to the lower end of each knocking rod 22.

[0037] The elastic connecting rod 19 drives the limit block 21 to shake up and down. At the same time, due to the connecting effect of the elastic strip 211, all the limit blocks 21 shake. At the same time, the knocking rod 22 drives the knocking hammer 24 to repeatedly knock the sheet 7 to be rolled up and down, which is conducive to better cleaning of dirt on the sheet 7 to be rolled.

[0038] In certain preferred embodiments, Figure 5 and Figure 6 As shown, a rack 25 is provided on one side of the middle limit block 21, and a first gear 26 is meshedly connected to the other side of the rack 25. A first bevel gear 27 is glued to one side of the first gear 26. A sixth central axis 261 is passed through the center of the first gear 26 and the first bevel gear 27. A first connector 262 is fixedly connected to one end of the sixth central axis 261. A scraper 8 is also fixedly mounted on the two side plates 11 behind the cleaning mechanism 2, and the rear end of the first connector 262 is fixedly connected to the scraper 8. A second bevel gear 28 is meshedly connected below the first bevel gear 27, and a second gear 29 is glued to the bottom of the second bevel gear 28. A plurality of second gears 29 are also meshed and transmission-set on both sides of the second gear 29, and a cleaning brush 20 is glued to the bottom of each second gear 29.

[0039] A seventh central shaft 281 is provided through the center of each set of second bevel teeth 28 and second gear 29. A second connecting piece 282 is fixedly connected to the upper end of the seventh central shaft 281. The rear end of the second connecting piece 282 is fixedly connected to the scraper 8. A connecting piece 291 is provided through the center of each set of second gears 29 and cleaning brush 20. The connecting piece 291 is formed by the fixed connection of the central shaft at the bottom and a connecting plate at the top. The other end of the connecting plate is fixedly connected to the scraper 8.

[0040] While the limiting block 21 vibrates up and down, it drives the rack 25 to move up and down repeatedly. The rack 25 moves up and down repeatedly to engage the first gear 26 to rotate forward and backward repeatedly. The first gear 26 drives the first bevel gear 27 to rotate forward and backward repeatedly with the sixth central axis 261 as the axis. While the first bevel gear 27 rotates, it engages the second bevel gear 28 to rotate. While the second bevel gear 28 rotates, it drives the second gear 29 and the cleaning brush 20 to rotate with the seventh central axis 281 as the axis. At the same time, the first rotating second gear 29 drives the rotation of the cleaning brush 20 below it through meshing transmission. The rotation of the cleaning brush 20 can brush the surface of the plate to assist in cleaning the dirt on the plate.

[0041] In some preferred embodiments, as Figure 1 shown, a to-be-rolled plate 7 is placed above the front support plate 111, the transmission assembly 12 and the dust removal assembly 13.

[0042] In some preferred embodiments, as Figure 3 and Figure 7 shown, the transmission assembly 12 includes a first central axis 121 penetrating through the two side plates 11. A first shaft roller 122 is sleeved on the first central axis 121 between the two side plates 11. A second central axis 123 is further penetrated through the two side plates 11 behind the first central axis 121. A second shaft roller 124 is sleeved on the second central axis 123 between the two side plates 11. One end of the first central axis 121 penetrates through one side plate 11 and is connected with a coupling 1211. The other end of the coupling 1211 is connected with a motor 1212. The motor 1212 is fixedly installed in a motor frame 1213. The motor frame 1213 is fixedly installed on the side plate 11. The motor 1212 serves as a power source and drives the first central axis 121 to rotate through the coupling 1211. At the same time, the first central axis 121 drives the first shaft roller 122 to rotate. The rotation of the first shaft roller 122 is used for the conveying work of the to-be-rolled plate 7. While the to-be-rolled plate 7 is conveyed backward, the second shaft roller 124 rotates with the second central axis 123 as the axis to keep the conveying work stable.

[0043] In some preferred embodiments, as Figure 3As shown, the dust removal assembly 13 includes a third central axis 131 passing through the two side plates 11. A first driving roller 132 is sleeved on the third central axis 131. A hard wear-resistant brush 133 is adhesively bonded to the outer side of the first driving roller 132. A fourth central axis 134 also passes through the two side plates 11 behind the third central axis 131. A second driving roller 135 is sleeved on the fourth central axis 134. A soft adsorption brush 136 is adhesively bonded to the outer side of the second driving roller 135. Both the third central axis 131 and the fourth central axis 134 are located between the first central axis 121 and the second central axis 123. During the backward transmission of the to-be-rolled sheet 7, it sequentially contacts and drives with the hard wear-resistant brush 133 and the soft adsorption brush 136, causing the first driving roller 132 to drive the hard wear-resistant brush 133 to rotate around the third central axis 131, and the second driving roller 135 to drive the soft adsorption brush 136 to rotate around the fourth central axis 134, so as to clean the dirt on the back side of the to-be-rolled sheet 7.

[0044] In some alternative embodiments, the hard wear-resistant brush 133 uses hard bristles and is used to peel off large attachments on the surface of the to-be-rolled sheet 7; the soft adsorption brush 136 uses softer and denser bristles and is used to finely remove residual particles and electrostatically adsorbed dust.

[0045] In some preferred embodiments, as Figure 3 shown, the oscillation area 17 includes four oscillation belt parts, namely a first oscillation belt 171, a second oscillation belt 172, a third oscillation belt 173 and a fourth oscillation belt 174. The four oscillation belt parts are evenly distributed from top to bottom in sequence, and the undulation degrees decrease in sequence. It is beneficial that while the roller 1832 rolls on the fourth oscillation belt 174, the third oscillation belt 173, the second oscillation belt 172 and the first oscillation belt 171 from bottom to top in sequence, the rolling of the roller 1832 becomes more bumpy. Through the connection of the fifth central axis 1831, the vibration block 183 and the connecting rod 185, the elastic connecting rod 19 drives the cleaning mechanism 2 to shake more violently, so as to strengthen the knocking and cleaning force on the to-be-rolled sheet 7.

[0046] In some preferred embodiments, as Figure 2 shown, a front support plate 111 is fixedly installed in front of the side plate 11. The front support plate 111 is used for the auxiliary support of the to-be-rolled sheet 7, so that the transmission of the to-be-rolled sheet 7 is more stable.

[0047] In some preferred embodiments, as Figure 4As shown, a four-roller mechanism 3 is also provided on the support 6, located behind the scraper 8. One end of the four-roller mechanism 3 is connected to a drive mechanism 4, and the other end is connected to an adjustment mechanism 5. The four-roller mechanism 3 is used to bend the sheet material 7 to form. The drive mechanism 4 serves as the power source for the four-roller mechanism 3, ensuring continuous feeding and roller rotation of the sheet material 7, providing the basic forming power. The adjustment mechanism 5 is used to dynamically adjust the roller gap to meet the bending requirements of the different sheet materials 7 to ensure forming quality. The specific components and connection methods of the four-roller mechanism 3, the drive mechanism 4, and the adjustment mechanism 5 are common knowledge in the art and will not be detailed here.

[0048] In the above embodiment, the sheet material 7 to be rolled is placed on the transmission component 12 and the dust removal component 13, and the transmission component 12 transmits the sheet material 7 to be rolled backward, and the sheet material 7 to be rolled passes through the limit plate 14 backward. When there is dirt on the sheet material 7 to be rolled, the dirt will press against the front side of the ramp slide 16 and push the ramp slide 16 backward. At the same time, the first spring 15 is stretched, and the ramp slide 16 contacts the roller 1832 during the backward movement. The roller 1832 rolls with the fifth center axis 1831 as the axis to adapt to the relative displacement with the ramp slide 16. The roller 1832 rolls onto the vibration zone 17. Due to the connection of the fifth center axis 1831, the vibration block 183 moves upward with the fifth center axis 1831, and the second spring 182 is shortened.

[0049] The vibration block 183 drives the connecting rod 185 to move upward. Since the roller 1832 rolls onto the vibration zone 17, the connecting rod 185 moves upward and continuously shakes up and down, and drives the limit block 21 to shake through the elastic connecting rod 19. At the same time, due to the connection effect of the elastic strip 211, all the limit blocks 21 shake, so that the knocking rod 22 drives the knocking hammer 24 to repeatedly knock the plate 7 to be rolled up and down, so that the dirt on the plate 7 to be rolled is knocked off. The firmer the dirt is, the further back the ramp slide 16 is pushed, the more violent the roller 1832 bumps on the vibration zone 17, and the more violent the limit block 21 shakes, so that the knocking rod 22 drives the knocking hammer 24 to knock the plate 7 to be rolled with greater force, thereby accelerating the cleaning effect of the dirt on the plate 7 to be rolled, and at the same time, the dust removal component 13 cleans the dirt on the back side of the plate 7 to be rolled.

[0050] Meanwhile, while the limiting block 21 vibrates up and down, it drives the rack 25 to move up and down repeatedly. The rack 25 moves up and down repeatedly to engage the first gear 26 to rotate forward and backward repeatedly. The first gear 26 drives the first bevel gear 27 to rotate forward and backward repeatedly with the sixth central axis 261 as the axis. While the first bevel gear 27 rotates, it engages the second bevel gear 28 to rotate. While the second bevel gear 28 rotates, it drives the second gear 29 and the cleaning brush 20 to rotate with the seventh central axis 281 as the axis. At the same time, the first rotating second gear 29 drives the rotation of the remaining second gears 29 through meshing transmission, and each of the remaining second gears 29 drives the rotation of the cleaning brush 20 below. The rotation of the cleaning brush 20 can brush the surface of the plate to assist in cleaning the dirt on the plate. It should be noted that if there is a large difference in the amount of dirt attached to both sides of the to-be-rolled plate 7, the side with more dirt attached should face up during feeding.

[0051] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0052] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.

9. A cleaning method for a plate by a four-roll numerically controlled plate bending machine according to claims 1-8, characterized in that: Place the to-be-rolled sheet on the transmission component and the dust removal component. The transmission component transports the to-be-rolled sheet backward. The to-be-rolled sheet passes through the limiting plate backward. When there is dirt on the to-be-rolled sheet, the dirt will abut against the front side of the slope slider and push the slope slider backward. At the same time, the first spring is stretched. During the backward movement of the slope slider, it contacts the roller. The roller rolls around the fifth central axis to adapt to the relative displacement with the slope slider. The roller rolls onto the oscillation area. Due to the connection of the fifth central axis, the vibration block moves upward with the fifth central axis, and the second spring shortens. At the same time, the vibration block drives the connecting rod to move upward. Since the roller rolls onto the oscillation area, while the connecting rod moves upward, it continuously jitters up and down. The elastic connecting rod drives the limiting block to jitter. At the same time, due to the connection of the elastic strip, all the limiting blocks jitter, causing the knocking rod to drive the knocking hammer to repeatedly knock the to-be-rolled sheet up and down, knocking off the dirt on the to-be-rolled sheet. The more firmly the dirt adheres, the farther the slope slider is pushed backward, the more violently the roller bumps on the oscillation area, and the more violently the limiting block jitters. As a result, the knocking rod drives the knocking hammer to apply a greater knocking force to the to-be-rolled sheet, accelerating the cleaning effect of the dirt on the to-be-rolled sheet. At the same time, the dust removal component cleans the dirt on the back side of the to-be-rolled sheet.
