Description

Technical Field

[0001] The present invention relates to the technical field of metal rolling, and specifically provides a self-lubricating rolling device with adjustable roll distance and roll temperature. Background Art

[0002] A rolling device is equipment for realizing the metal rolling process. Rolling refers to a processing method in which a metal blank passes through the gap between a pair of rotating rolls and is compressed by the pair of rotating rolls, resulting in a reduced metal cross-section and an increased length. The rolling device mainly consists of equipment such as rolls, drive motors, and worktables. After being processed by the rolling device, the metal has a certain size and shape.

[0003] After retrieval, the existing Chinese patent publication number is: CN218873242U, which provides a steel rolling device. By providing a rolling gap between two rolls, during rolling, the two rolls rotate in opposite directions, and the rolled piece passes through the rolling gap. The liquid inlet pipe is connected to a container storing lubricant, and the lubricant is sprayed from the spraying nozzle to the surface of the roll through the liquid inlet pipe, which can reduce the friction between the roll and the rolled piece, thereby reducing the wear of the roll and extending the service life of the roll;

[0004] Although the above patent can self-lubricate a pair of rolls, the above self-lubricating rolling device still has the following problems: After the above self-lubricating rolling device finishes working, due to heat exchange generated by the contact between the roll and the rolled piece, the temperature of the roll after work is increased. When using an external spraying device to spray coolant on the outside of the roll for cooling or setting a cooling pipe inside the roll, when using the internal cooling pipe to cool the roll, the cooling water first indirectly exchanges heat with the roll through the cooling pipe, and the heat exchange efficiency is low. The coolant cannot directly contact the inner wall of the roll. If the external spraying method is used, the coolant will also contact the high-temperature surrounding area outside the roll, which will also affect the heat exchange efficiency to a certain extent.

[0005] In view of the above problems, an innovative design is carried out on the basis of the original self-lubricating rolling device.

[0006] The purpose of the present invention is to provide a self-lubricating rolling device with adjustable roll distance and roll temperature. Using this device for work is used to solve the problem that the existing rolling device has poor cooling effect due to easy loss of coolant temperature during indirect heat exchange when cooling the inside of the roll.

[0037] To further understand the content of the present invention, the present invention will be described in detail in conjunction with the accompanying drawings.

[0038] Combined with Figure 1 and Figure 2 , a roll-spacing and roll-temperature adjustable self-lubricating rolling device includes a frame 1, a roll assembly 2 and a lubrication assembly 3. A rolling assembly 4 for driving the rotation of the roll assembly 2 is fixed outside the frame 1, and a spacing adjustment assembly 5 for adjusting the roll spacing between the roll assemblies 2 is arranged outside the rolling assembly 4. Liquid supply assemblies 7 are installed on both sides of the frame 1, and the end of the liquid supply assembly 7 is connected to a cooling assembly 10;

[0039] The present invention will be further described below with reference to the embodiments.

[0040] Please refer to Figures 3 - 9, the roll assembly 2 includes an upper roll 21 movably connected to the inner side of the frame 1, and a lower roll 22 is also arranged on the inner side of the frame 1, and the lower roll 22 and the upper roll 21 are aligned. Sliding grooves are formed on both sides of the frame 1, and the sliding grooves are slidably connected to the connecting shaft of the lower roll 22, so that the sliding trajectory of the lower roll 22 is limited.

[0041] The lubrication assembly 3 includes a gantry 31 movably connected to the outer side of the frame 1, and a storage cylinder 32 is slidably connected inside the gantry 31, and a high-pressure spray head 33 is connected to the end of the storage cylinder 32. The high-pressure spray head 33 and the storage cylinder 32 form a set of spraying components, and multiple sets of spraying components are provided, which can lubricate the working areas of the lower roll 22 and the upper roll 21.

[0042] The rolling assembly 4 includes a first gear 44 arranged outside the connecting shaft of the upper roll 21, and an auxiliary gear 43 is engaged on one side of the first gear 44, and the auxiliary gear 43 is arranged outside the frame 1, and a driving gear 42 is engaged on the other side of the auxiliary gear 43, and a driving motor 41 is connected to the outside of the driving gear 42, and a second gear 45 is engaged on one side of the driving gear 42, and the second gear 45 is arranged outside the connecting shaft of the lower roll 22, which can drive the lower roll 22 and the upper roll 21 to rotate synchronously and in opposite directions.

[0043] The spacing adjustment assembly 5 includes a support plate 54 fixed to one side of the frame 1, and an electric push rod 51 is installed at the upper end of the support plate 54, and a connecting rod 52 is connected to the upper end of the electric push rod 51, and a collar 53 and a positioning assembly 6 are respectively connected to the upper end of the connecting rod 52. The collar 53 is sleeved outside the branch pipe 73, and the branch pipe 73 is movably connected to the inside of the connecting shaft of the upper roll 21. Two sets of cooling assemblies 10 are arranged inside both the upper roll 21 and the lower roll 22, and each set of cooling assemblies 10 is connected to a set of branch pipes 73. The two sets of branch pipes 73 are movably connected to a set of conveying pipes 72, which is convenient for adjusting the spacing between the lower roll 22 and the upper roll 21.

[0044] The positioning assembly 6 includes a cross plate 61 fixed to the outside of the frame 1, and a movable plate 62 is connected to the upper end of the connecting rod 52, and a limiting block 63 is fixed inside the movable plate 62. A limiting groove 64 is formed on one side of the frame 1, and the limiting groove 64 is slidably connected to the limiting block 63, which can support the rolled material.

[0045] A linkage assembly 8 is connected to one side of the first gear 44, and a second rotating assembly 9 is arranged on the other side of the first gear 44. A set of reverse linkage assemblies 8 and second rotating assemblies 9 are arranged on both sides of the second gear 45, so that the internal operation modes of the second gear 45 and the first gear 44 are the same.

[0046] The linkage assembly 8 includes a first fixing plate 81 fixed to the outer side of the connecting shaft of the first gear 44. A first rotating assembly 82 is provided on the surface of the first fixing plate 81, and multiple groups of the first rotating assemblies 82 are provided. The first rotating assembly 82 includes a first ratchet 821 movably connected to the surface of the first fixing plate 81. A first spring 822 is connected to the outer side of the first ratchet 821, and the other side of the first spring 822 is connected to a first connecting block 823. The first connecting block 823 is fixed to the surface of the first fixing plate 81. A first clamping rod 824 is engaged between two groups of the first ratchets 821. One end of the first clamping rod 824 is connected to the upper roller 21, and the other end of the first clamping rod 824 is connected to a support ring 83. The support ring 83 is sleeved on the outer side of the connecting shaft of the first gear 44, so that the first clamping rod 824 can drive the upper roller 21 to rotate, but the upper roller 21 does not rotate during reverse rotation.

[0047] The second rotating assembly 9 includes a second clamping rod 95 fixed to the outer side of the first gear 44. A second fixing plate 91 is connected to the outer side of the branch pipe 73. A second ratchet 92 is movably connected to the surface of the second fixing plate 91. A second connecting block 94 is further fixed to the surface of the second fixing plate 91. A second spring 93 is connected between the second connecting block 94 and the second ratchet 92. The direction of the second ratchet 92 is the same as that of the first ratchet 821, so that the second fixing plate 91 is fixed during forward rotation and rotates during reverse rotation.

[0048] Specifically, on one side of the connecting shafts of the upper roll 21 and the lower roll 22, a first gear 44 and a second gear 45 are fixed externally. And on one side of the connecting shaft of the lower roll 22, it is arranged in a sliding groove opened on the side surface of the frame 1. By starting the driving motor 41 to drive the driving gear 42 to rotate, the outer side of the driving gear 42 meshes with the auxiliary gear 43 and the second gear 45, and the auxiliary gear 43 meshes with the first gear 44. At this time, the driving gear 42, the auxiliary gear 43, the first gear 44 and the second gear 45 rotate synchronously, and the rotation directions of the first gear 44 and the second gear 45 are opposite, so that the upper roll 21 and the lower roll 22 rotate in opposite directions to press the metal. The pressed metal passes through the gap between the cross plate 61 and the movable plate 62, and can position and clamp the discharged metal. If the thickness of the rolled metal changes, the distance between the upper roll 21 and the lower roll 22 needs to be adjusted. At this time, first drive the electric push rod 51 to contract. The upper end of the electric push rod 51 is connected to the connecting rod 52, and both ends of the connecting rod 52 are respectively connected to the collar 53 and the movable plate 62. At this time, the movable plate 62 moves downward along the moving direction of the limiting block 63 in the limiting groove 64, so as to complete the adjustment of the distance between the cross plate 61 and the movable plate 62. The downward movement of the collar 53 drives the branch pipe 73 sleeved inside to move downward. The branch pipe 73 is movably connected to the inside of the connecting shaft of the lower roll 22, and the branch pipe 73 drives the lower roll 22 to move downward through the connecting shaft, so that the distance between the lower roll 22 and the upper roll 21 changes. The lower roll 22 drives the second gear 45 to move downward. At this time, the second gear 45 no longer meshes with the driving gear 42. The staff grabs the handle 56 and drives the rotating plate 55 to rotate clockwise around the rotating shaft of the auxiliary gear 43. The driving gear 42 slides along the arc-shaped rail 57, and then manually rotates the driving gear 42 by a certain angle so that the driving gear 42 meshes with the second gear 45 again. At this time, the adjustment of the distance between the first gear 44 and the second gear 45 is completed. Under normal working conditions, the first gear 44 rotates forward, driving the fixing plate one 81 fixed on the outer side of the shaft on the back of the first gear 44 to rotate synchronously. The outer side of the fixing plate one 81 is movably connected with a first rotating assembly 82, and multiple groups of the first rotating assemblies 82 are arranged at equal angles on the fixing plate one 81. At this time, the forward rotation of the fixing plate one 81 drives the ratchet tooth one 821 to rotate. A latch rod one 824 is engaged between the two ratchet teeth one 821. Due to the maximum elongation of the spring one 822 restricting the rotation range of the ratchet tooth one 821, the ratchet tooth one 821 cannot disengage from the latch rod one 824, thus driving the latch rod one 824 to rotate. The latch rod one 824 drives the upper roll 21 connected thereto to rotate. The second gear 45 on the outer side of the lower roll 22 is also provided with the same structure, but the direction of the ratchet tooth one 821 in the first rotating assembly 82 is opposite. At the same time, a latch rod two 95 is connected to one side of the first gear 44. The latch rod two 95 rotates following the forward rotation of the first gear 44, and the latch rod two 95 is stuck between two ratchet teeth two 92. The second rotating assembly 9 is connected to the branch pipe 73. Since the branch pipe 73 is movably connected to the connecting shaft,The branch pipe 73 does not rotate with the first gear 44, the second rotating assembly 9 is in a static state, and when the second locking lever 95 rotates, it will squeeze the second ratchet 92 to rotate around the axis, causing the second spring 93 to be compressed. The second ratchet 92 rotates around the axis to ensure that the second locking lever 95 can rotate smoothly in a circle without affecting the normal operation of the first gear 44. When the rolling operation comes into contact, first start the water pump inside the cooling water tank 71, convey the cooling water into the conveying pipe 72, and then convey it into the cooling cavity 102 through the branch pipe 73. The branch pipe 73 is connected to the upper roller 21 through the bearing 101. At this time, start the driving motor 41 to reverse, causing the rotation directions of the first gear 44 and the second gear 45 to change. The first gear 44 drives the fixing plate 81 to change the rotation direction. At this time, the first ratchet 821 on the fixing plate 81 can be pushed by the first locking lever 824 to rotate, and the first spring 822 is compressed. At this time, the first ratchet 821 no longer pushes the first locking lever 824 to rotate. At this time, the upper roller 21 is in a static state and is supported by the support ring 83 sleeved outside the rotating shaft of the first gear 44. When the first gear 44 rotates in reverse, it will drive the second locking lever 95 to rotate. The reversed second locking lever 95 can no longer squeeze the second ratchet 92, causing the second ratchet 92 to drive the fixing plate 91 to rotate, so that the fixing plate 91 drives the branch pipe 73 to rotate. The branch pipe 73 is movably connected to the conveying pipe 72, so that the branch pipe 73 drives the connected cooling cavity 102 to rotate. When the cooling cavity 102 rotates, the centrifugal force will be generated when the internal coolant is discharged from the water outlet 103, accelerating the discharge of the coolant. And cooling components 10 are arranged on both sides of the upper roller 21. The rotation drives of the two groups of cooling components 10 are the same, which can ensure that the cooling effects at both ends of the upper roller 21 are the same, improve the cooling quality, can better control the temperature of the roller, avoid the thermal deformation of the roller, and the coolant can be in direct contact with the inner wall of the upper roller 21, improving the heat exchange efficiency.

[0049] Please refer to Figures 10 - 14 The liquid supply assembly 7 includes cooling water tanks 71 fixed on both sides of the frame 1. A water pump is arranged inside the cooling water tank 71, and the output end of the water pump is connected to a conveying pipe 72. One side of the conveying pipe 72 is connected to a branch pipe 73, which can ensure the normal conveyance of the coolant.

[0050] The cooling component 10 includes a cooling cavity 102 connected to the end of the branch pipe 73. A water outlet 103 is arranged outside the cooling cavity 102, and multiple groups of water outlets 103 are arranged. The cooling cavity 102 is arranged inside the roller assembly 2, so that the coolant is in direct contact with the inner wall of the roller assembly 2.

[0051] A water permeable cylinder 104 is fixed inside the cooling chamber 102, and a water leakage groove 106 is opened inside the upper roller 21 and the lower roller 22, and a water outlet pipe 105 is arranged inside the water leakage groove 106, and the water outlet pipe 105 runs through one side of the upper roller 21, and a water control component 11 is arranged inside the water permeable cylinder 104, and the water control component 11 includes a baffle 111 arranged inside the water permeable cylinder 104, and the baffle 111 is provided with multiple groups, and a connecting rod 112 is connected between the multiple groups of baffles 111, and the connecting rod 112 is connected in the middle A center rod 113 is connected, and a toggle assembly 114 is arranged on the outside of the center rod 113. The toggle assembly 114 includes a vertical rod 1141 fixed on the center rod 113, and a magnet 1142 is connected to the upper end of the vertical rod 1141. An electromagnet 1144 is arranged on the inner wall of the branch pipe 73, and the electromagnet 1144 attracts the magnet 1142 when energized. A spring 1143 is connected between the vertical rod 1141 and the inner wall of the branch pipe 73, which can concentrate the cooling of the middle section of the roller assembly 2.

[0052] Specifically, cooling water tanks 71 are fixed on both sides of the frame 1. The cooling water tanks 71 are movably connected to two groups of branch pipes 73 through conveying pipes 72. The branch pipes 73 transport the coolant into the interior of the cooling cavity 102. The cooling cavity 102 is provided with multiple groups of water outlets 103, allowing the coolant to directly contact the inner walls of the upper roller 21 or the lower roller 22 through the water outlets 103, adopting a direct heat exchange method. And a water leakage groove 106 is arranged inside the upper roller 21 or the lower roller 22, and a water outlet pipe 105 is installed inside the water leakage groove 106. When it is necessary to drain the coolant inside the upper roller 21, the end of the water outlet pipe 105 can be connected to a water pump, so that the water outlet pipe 105 uses the water leakage groove 106 to pump away the coolant inside the upper roller 21 or the lower roller 22. Moreover, after the upper roller 21 and the lower roller 22 are used, due to the linear expansion of the upper roller 21 and the lower roller 22, the temperature in the middle of the upper roller 21 and the lower roller 22 is higher than that at both ends, resulting in a situation where the surface of the upper roller 21 and the lower roller 22 is prone to cracking. In view of the above situation, the electromagnet 1144 can be energized first, so that the electromagnet 1144 attracts the magnet 1142. The magnet 1142 drives the central rod 113 to rotate. The central rod 113 drives the baffle 111 to rotate through the connecting rod 112 connected thereto, so that the baffle 111 blocks the holes of the water permeable cylinder 104. The length of the water permeable cylinder 104 is less than the length of the cooling cavity 102, so that the coolant inside the cooling cavity 102 can only pass through the front water permeable holes, and the coolant concentrates on the middle section of the upper roller 21. The detection component 12 is composed of a temperature sensor A121 and a temperature sensor B122. When the temperature detected by the temperature sensor A121 located in the middle section of the upper roller 21 is the same as the temperature detected by the temperature sensor B122 located on both sides of the upper roller 21, the electromagnet 1144 is powered off, and the spring three 1143 drives the magnet 1142 to reset so that the baffle 111 no longer blocks the water permeable holes of the water permeable cylinder 104, and the overall cooling can start. Compared with using a relatively large amount of coolant for overall cooling, the above structure can save coolant while cooling targeted, reducing the possibility of surface cracking of the roller surface.
