[0023] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0024] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention. Example 1

[0025] A rolling device for sheet metal processing, such as Figure 1 - Fig. 9 As shown, it includes frames 1 on both sides and protective covers 3 fixed to opposite sides of the two frames 1, a rolling part 2 is arranged in the cavity formed by the frames 1 and the protective covers 3, and avoidance openings for plates to enter and exit are opened at both ends of the protective covers 3.

[0026] The rolling section 2 includes adjusting arms 6 located on both sides and multiple groups of rolling rollers 5 arranged between the adjusting arms 6. The adjusting arms 6 on each side are arranged in two symmetrical forms, and one end of the adjusting arm 6 is provided with an adjusting component 7 for driving the angle switching of the adjusting arm 6. The other end of the adjusting arm 6 is rotatably connected to the inner wall of the protective cover 3 through the protective cover 3, and the outer side of the adjusting arm 6 is provided with a driving component 8 for rotating the rolling rollers 5.

[0027] The adjustment assembly 7 includes a slider 16 and a telescope 17. The slider 16 is slidably connected to the inner wall of the frame 1. The telescope 17 is fixed to the inner wall of the frame 1 by bolts, and the telescopic end of the telescope 17 is fixed to the side wall of the slider 16 by bolts. The side wall of the slider 16 is rotatably connected to two symmetrical connecting rods 15, and the other end of the connecting rod 15 is rotatably connected to the end of the adjustment arm 6.

[0028] When the device is in use, the plate can be placed from one end of the protective cover 3, and the opening of the two rolling rollers 5 at this end is the largest, and then the plate is pushed between the two rolling rollers 5 at this end, and then the rolling rollers 5 are driven to rotate by the driving component 8. The rolling rollers 5 roll the plate, and the plate will be gradually rolled through multiple rolling rollers 5 in sequence and finally formed. During adjustment, the slider 16 can be driven to slide through the telescopic device 17, thereby driving the adjusting arm 6 to rotate through the connecting rod 15 to change the gap between the rolling rollers 5.

[0029] The device, by arranging a plurality of rolling rollers 5, adjusting arms 6 and adjusting components 7, can specifically adjust the gaps between the rolling rollers 5 according to actual needs, thereby changing the thickness of the metal sheet finally rolled. At the same time, since the adjusting arms 6 are linear, the gaps between the plurality of rolling rollers 5 are in an arithmetic progression, so that each rolling roller 5 has the same task of changing the metal thickness, thereby being evenly stressed and increasing the service life.

[0030] To solve the driver problem; Figure 3As shown, the rolling roller 5 is rotatably connected to the adjusting arm 6 via a roller shaft 10, and a driven sprocket 11 is fixed to the outer wall of the roller shaft 10, and adjacent driven sprockets 11 are coupled via a chain 12, the protective cover 3 is rotatably connected to the frame 1, and a driving sprocket 13 is fixed to the outer wall of the protective cover 3, and the driving sprocket 13 and one of the driven sprockets 11 are coupled via a chain 12, a driving motor 9 is fixed to the outer wall of the frame 1, and the output shaft of the driving motor 9 is connected to the end of the protective cover 3 via a coupling, and the two protective covers 3 are coupled via a gear set.

[0031] When the driving motor 9 is started, it can drive the protective cover 3 to rotate, thereby driving the driving sprocket 13 to rotate, and then driving the rolling rollers 5 to rotate through the chain 12 and the driven sprocket 11, and through the coordination of gears, the rolling rollers 5 in the same group have the same rotation speed and opposite direction.

[0032] In this device, the protective cover 3 is used as the rotation center of the adjusting arm 6 on the basis of using the adjusting arm 6. At the same time, the protective cover 3 is used as the "driving shaft" of the rolling roller 5. Therefore, no matter how the adjusting arm 6 is adjusted, the axial position of the protective cover 3 remains unchanged, so that the position of the driving motor 9 remains unchanged, thereby preventing the wires of the driving motor 9 from being entangled or worn out due to movement, thereby increasing safety.

[0033] In order to solve the power control problem; such as Figure 1 , 5 As shown, a power regulating part 4 is provided on the side wall of the frame 1, and the power regulating part 4 includes a magnetic core 18, a primary coil 21 and a secondary coil 22. The magnetic core 18 is fixed to the side wall of the frame 1, and the primary coil 21 and the secondary coil 22 are respectively wound on both sides of the magnetic core 18. A conductive contact 19 is fixed to the side wall of the slider 16 through a connecting plate 20. The top of the conductive contact 19 contacts and electrically cooperates with the outer wall of the secondary coil 22. The primary coil 21 is connected to an external AC power supply, and one end of the secondary coil 22 and the conductive contact 19 are respectively connected to the two ends of the drive motor 9.

[0034] As the thickness of the metal sheet after rolling is smaller, the required rolling power is greater, that is, the required rotational power of the rolling roller 5 is greater. In this device, when the slider 16 slides and adjusts the angle of the adjusting arm 6, the angle between the two adjusting arms 6 becomes smaller. At the same time, the movement of the slider 16 will also drive the conductive contact 19 to move, thereby changing the matching position of the conductive contact 19 and the secondary coil 22, increasing the number of turns of the secondary coil 22 connected to the circuit, thereby increasing the output power, and increasing the input power of the drive motor 9.

[0035] This device, by providing components such as a magnetic core 18, a primary coil 21, and a secondary coil 22, can make it possible to change the power of the driving motor 9 by moving the slider 16 on the basis of targeted adjustment of the rolling thickness, thereby achieving adaptive matching of the rolling thickness and the rolling power.

[0036] When the present embodiment is in use, the plate can be put in from one end of the protective cover 3, and the opening of the two rolling rollers 5 at this end is the largest, and then the plate is pushed into the middle of the two rolling rollers 5 at this end, and then the rolling rollers 5 are driven to rotate by the driving assembly 8, and the rolling rollers 5 roll the plate, and the plate will be gradually rolled through multiple rolling rollers 5 in sequence and finally formed. When adjusting, the slider 16 can be driven to slide by the telescopic device 17, so that the adjusting arm 6 can be driven to rotate through the connecting rod 15 to change the gap between the rolling rollers 5. When the driving motor 9 is started, it can drive the protective cover 3 to rotate, thereby driving the driving sprocket 13 to rotate, so that the chain 12 and the driven sprocket 13 can be connected. The sprocket 11 drives the rolling roller 5 to rotate, and through the gear matching, the rolling rollers 5 in the same group have the same rotation speed and opposite direction. The smaller the thickness of the metal plate to be rolled, the greater the rolling power required, that is, the greater the rotation power of the rolling roller 5. In this device, the slider 16 slides to adjust the angle of the adjusting arm 6, and the smaller the angle between the two adjusting arms 6 is. At the same time, the movement of the slider 16 will also drive the conductive contact 19 to move, thereby changing the matching position of the conductive contact 19 and the secondary coil 22, which increases the number of turns of the secondary coil 22 connected to the circuit, thereby increasing the output power, and increasing the input power of the drive motor 9. Example 2

[0037] A rolling device for sheet metal processing, such as Figure 1 - Fig. 9 As shown, in order to solve the heat dissipation problem, this embodiment makes the following improvements on the basis of embodiment 1: the rolling roller 5 and the roller shaft 10 are both hollow structures, and the end of the roller shaft 10 is rotatably connected with a transition ring 23, and multiple transition rings 23 are connected through a multi-way tube 24, and a fluid drive mechanism 25 and a radiator 26 are connected between two multi-way tubes 24 in the same group.

[0038] During hot rolling, the contact between the rolling roller 5 and the plate will cause the temperature to rise, which is prone to failure and deformation. When the device is used, the fluid drive mechanism 25 can drive the cooling medium to circulate, and then dissipate the heat through the radiator 26. After the heat is dissipated, the low-temperature cooling medium enters the rolling roller 5, takes away the heat in the rolling roller 5, and then enters the fluid drive mechanism 25 through the multi-way pipe 24 to complete a cycle.

[0039] The device, by arranging the rolling roller 5 and the roller shaft 10 as a cavity, arranges a fluid drive mechanism 25 and a radiator 26, and can utilize the circulating flow of the cooling medium to dissipate the heat of the rolling roller 5, thereby reducing the temperature of the rolling roller 5 and preventing the rolling roller 5 from failure and deformation due to high temperature.

[0040] In order to solve the problem of adaptive control of heat dissipation speed, such as Figure 7 , 8 As shown in Figure 9, the fluid drive mechanism 25 includes a base 27, a slide 29, a motor 30, and a pump head 32. The slide 29 is slidably connected to the top outer wall of the base 27, the pump head 32 is fixed to the top outer wall of the base 27, the motor 30 is fixed to the side wall of the slide 29 by bolts, the output shaft of the motor 30 is fixed with a fixed diameter pulley 28, the input shaft of the pump head 32 is fixed with a variable diameter pulley 33, and the fixed diameter pulley 28 and the variable diameter pulley 33 are matched through the transmission of a synchronous belt 31.

[0041] The variable diameter pulley 33 includes a ratchet 35, a synchronous disk 37 and a plurality of belt blocks 36 which are slidably connected to the radial direction of the ratchet 35 and cooperate with the synchronous belt 31 for transmission. The ratchet 35 is fixed to the input shaft of the pump head 32, and the synchronous disk 37 is rotationally connected to the input shaft of the pump head 32. A limiting column 39 is fixed to the side wall of the belt block 36, and an inclined groove 38 which cooperates with the limiting column 39 for movably limiting is formed on the inner wall of the synchronous disk 37, and a torsion spring 40 is buckled with the synchronous disk 37 on the opposite side of the ratchet 35.

[0042] The fluid drive mechanism 25 also includes a telescopic controller 34 for driving the slide 29, and the telescopic controller 34 includes a cylinder body 41, a piston 42 slidably connected to the inner wall of the cylinder body 41, and a piston rod 43 fixed to the side wall of the piston 42. The cylinder body 41 is fixed to the outer wall of the base 27, and the other end of the piston rod 43 is fixed to the side wall of the slide 29. The inner cavity of the cylinder body 41 is connected to the heat exchange tube 14 through the connecting rod 44, and the other end of the heat exchange tube 14 is in a closed state.

[0043] The heat exchange tube 14 is located inside the water inlet of the pump head 32 , and the inner cavities of the heat exchange tube 14 , the connecting rod 44 , and the cylinder body 41 are filled with a mixed gas of nitrogen dioxide and nitrogen tetroxide.

[0044] When the temperature of the cooling medium at the water inlet of the pump head 32 is high, it means that the temperature of the rolling roller 5 is high. At this time, the heat exchange tube 14 will sense the temperature, and the inner cavity temperature of the heat exchange tube 14 will increase. Therefore, on the one hand, the gas will expand, and on the other hand, the chemical equilibrium of nitrogen dioxide and nitrogen tetroxide will move in the direction of generating nitrogen dioxide, so that the gas will expand twice as much as before, so that the piston 42 is driven by the gas pressure to move the slide 29, and the axial distance between the fixed-diameter pulley 28 and the variable-diameter pulley 33 increases, while the length of the synchronous belt 31 remains unchanged, thereby applying an inward tensioning force to the belt block 36, causing the belt block 36 to shrink inward, reducing the transmission radius of the entire variable-diameter pulley 33, so that the speed of the fixed-diameter pulley 28 remains unchanged, the speed of the variable-diameter pulley 33 increases, the circulation speed of the cooling medium increases, and the heat dissipation speed increases.

[0045] This device, by setting up a fluid driving mechanism 25, can, on the one hand, adjust the heat dissipation speed according to the temperature of the rolling roller 5 to ensure the reliability of heat dissipation. On the other hand, it uses the characteristics of thermal expansion of the gas and chemical equilibrium movement to achieve a change in the transmission ratio, thereby realizing the automatic adjustment function of the heat dissipation speed and the water temperature on the water inlet side. In addition, by setting up a synchronous disk 37, it can ensure that the transmission radius of multiple belt blocks 36 is the same, thereby preventing abnormal wear of the synchronous belt 31 caused by transmission vibration.

[0046] When this embodiment is in use, during hot rolling, the rolling roller 5 contacts the plate, causing the temperature to rise, which is prone to failure and deformation. When this device is in use, the fluid drive mechanism 25 can drive the cooling medium to circulate, and then dissipate heat through the radiator 26. After heat dissipation, the low-temperature cooling medium enters the rolling roller 5, takes away the heat in the rolling roller 5, and then enters the fluid drive mechanism 25 through the multi-way pipe 24 to complete a cycle. When the cooling medium temperature at the water inlet of the pump head 32 is high, it means that the temperature of the rolling roller 5 is high. At this time, the heat exchange tube 14 will sense the temperature, and the inner cavity temperature of the heat exchange tube 14 will rise, thereby on the one hand The gas will expand. On the other hand, the chemical equilibrium of nitrogen dioxide and nitrogen tetroxide will move in the direction of generating nitrogen dioxide, and the combined effect will cause the gas to expand twice. As a result, the piston 42 is driven by the gas pressure to move the slide 29, and the axial distance between the fixed-diameter pulley 28 and the variable-diameter pulley 33 increases, while the length of the synchronous belt 31 remains unchanged, thereby applying an inward tensioning force to the belt block 36, causing the belt block 36 to shrink inward, reducing the transmission radius of the entire variable-diameter pulley 33, thereby keeping the speed of the fixed-diameter pulley 28 unchanged and the speed of the variable-diameter pulley 33 increased, increasing the circulation speed of the cooling medium and increasing the heat dissipation speed.
