Description
Technical Field
[0001] The utility model relates to the technical field of plate and strip forming, and in particular to a five-roller finishing embossing machine. Background Technology
[0002] The five-roll mill is a mainstream plate and strip rolling machine with mature technology. It is mainly used for rolling and shaping (also called finishing) or surface embossing of plates or strips. It has the advantages of high output, high quality of finished products, low consumption, low difficulty in equipment manufacturing and low maintenance. Usually, the workpiece of the five-roll mill passes through the working roll and the lower intermediate roll. Under the action of the oil cylinder, the workpiece is rolled into the required smooth or patterned plate or strip. Therefore, the working roll and the lower intermediate roll are the rolls that wear the fastest. When switching the embossing and finishing (shaping) processes, the working roll also needs to be replaced with a smooth roll or an embossing roll according to the process. Therefore, in the daily production and maintenance of the five-roll mill, the working roll and the lower intermediate roll are replaced frequently. However, the existing five-roll mill structure is relatively complex. When replacing the working roll and the lower intermediate roll, many parts need to be disassembled to complete the operation. There are problems such as cumbersome roll replacement, long replacement time, and low work efficiency.
[0003] The technical problem to be solved by this application is: how to solve the inconvenience of changing rolls in the existing five-roller rolling mill. Contents of utility model
[0004] In order to overcome the shortcomings of the prior art, the purpose of the utility model is to provide a five-roller finishing embossing machine, which has the characteristics of simple structure and convenient roller replacement.
[0005] The technical solution adopted by the utility model is: a five-roller finishing embossing machine, including a frame and a rolling mechanism installed on the frame, the frame is provided with mounting grooves for installing the rolling mechanism on opposite sides, the rolling mechanism includes an upper supporting roller, an upper intermediate roller, a working roller, a lower intermediate roller and a lower supporting roller arranged in sequence from top to bottom along the height direction of the mounting groove, the upper supporting roller, the upper intermediate roller, the working roller, the lower intermediate roller and the lower supporting roller can all move along the height direction of the mounting groove, and also includes a roller changing mechanism;
[0006] The roll changing mechanism includes a roll changing frame arranged on one side of the frame, a first guide rail and a second guide rail arranged in the mounting groove, a roll changing slide slidably connected to the roll changing frame, and a first roll changing power member driving the roll changing slide to move. The working roll is slidably connected to the first guide rail, the roll changing frame is provided with a first receiving rail docking with the first guide rail, the lower intermediate roll is slidably connected to the second guide rail, the roll changing frame is provided with a second receiving rail docking with the first guide rail, a draw hook is provided on the roll changing slide, and a draw ring corresponding to the draw hook is provided on the working roll and the lower intermediate roll.
[0007] For the five-roll finishing embossing machine of the present application, when it is necessary to replace the working roll and the lower intermediate roll, first lower the lower support roll until it separates from the lower intermediate roll, then dock the first guide rail with the first receiving rail and the second guide rail with the second receiving rail. Next, the first roll-changing power component drives the roll-changing slide table to slide towards the machine frame. Then, make the hook on the roll-changing slide table overlap with the pull ring. Subsequently, the first roll-changing power component drives the roll-changing slide table to reset. After pulling the working roll and the lower intermediate roll out of the machine frame onto the roll-changing rack, separate the hook from the pull ring, and then use a lifting device such as a crane to remove the working roll and the lower intermediate roll on the roll-changing rack. After placing the new working roll and the lower intermediate roll, overlap the hook with the pull rings on the new working roll and the lower intermediate roll. Then, the first roll-changing power component drives the roll-changing slide table to push the new working roll and the lower intermediate roll into the installation groove to complete the roll change. The roll-changing mechanism of the present application has a simple and reliable structure, simplifies the roll-changing operation process, makes it more simple and convenient, and greatly improves the working efficiency of roll changing and reduces the difficulty of roll changing.
[0008] In some embodiments, a first support block and a second support block are installed at intervals along the height direction in the installation groove. The upper support roll is arranged on the top of the first support block. The upper intermediate roll is slidably connected to the first support block. The working roll is arranged between the first support block and the second support block, and the working roll is slidably connected to the first support block and the second support block. The lower intermediate roll is slidably connected to the second support block. The lower support roll is arranged at the bottom of the second support block.
[0009] Adopting the above technical solution, the first support block is used to limit the movement range of the upper support roll and the upper intermediate roll in the height direction of the installation groove to prevent the upper support roll and the upper intermediate roll from falling. The second support block is used to limit the movement range of the working roll, the lower intermediate roll and the lower support roll in the height direction of the installation groove, which can prevent the working roll from falling and can also prevent the lower support roll and the lower intermediate roll from rising excessively and causing equipment damage.
[0010] In some embodiments, both ends of the upper support roll are connected with a first bearing seat, and the first bearing seat is slidably connected to the machine frame. Both ends of the upper intermediate roll are connected with a second bearing seat, and the second bearing seat is slidably connected to the first support block. Both ends of the working roll are connected with a third bearing seat, and the third bearing seat is slidably connected to the first support block and the second support block. The lower intermediate roll is provided with a fourth bearing seat, and the fourth bearing seat is slidably connected to the second support block. Both ends of the lower support roll are connected with a fifth bearing seat, and the fifth bearing seat is slidably connected to the machine frame.
[0011] In some embodiments, the first guide rail is installed on the top of the first support block, and a first guide wheel corresponding to the first guide rail is arranged on the third bearing seat. The second guide rail is installed on the top of the fifth bearing seat, and a second guide wheel corresponding to the second guide rail is arranged on the fourth bearing seat.
[0012] With the above technical solution, by slidingly connecting the first guide wheel with the first guide rail and the first receiving rail, and the second guide wheel with the second guide rail and the second receiving rail, it is convenient to load and unload the work roll and the lower intermediate roll.
[0013] In some embodiments, the roll changing mechanism further includes a first supporting rail assembly. The first supporting rail assembly includes a first supporting rail power member, a pull rod and a supporting block. The first supporting rail power member is installed on the frame, and the first supporting rail power member is located on the side of the second guide rail. The pull rod is connected to the output end of the first supporting rail power member, and the supporting block is rotatably connected to the pull rod. The first supporting rail power member is used to drive the supporting block to lift the second guide rail to be flush with the second receiving rail.
[0014] With the above technical solution, since the second work roll will rise and fall with the lower supporting roll, during the roll changing operation, the lower supporting roll is usually at the lowest point. In order to ensure that the second guide rail and the second receiving rail can be smoothly docked, the first supporting rail power member is used to drive the supporting block to lift the second guide rail to be flush with the second receiving rail, so that the lower intermediate roll can smoothly enter and exit the frame along the second guide rail and the second receiving rail for replacement. And the supporting block is set to be rotatably connected to the pull rod, so that when not changing the roll, the supporting block can be rotated by a certain angle to prevent the supporting block from interfering with the lifting of the lower receiving roll.
[0015] In some embodiments, a first buffer member and a second buffer member are provided on the first support block. The first buffer member is used to support the first bearing seat, and the second buffer member is used to support the second bearing seat;
[0016] A third buffer member and a fourth buffer member are provided on the second support block. The third buffer member is used to support the first guide rail, and the fourth buffer member is used to support the third bearing seat.
[0017] With the above technical solution, by providing the first buffer member and the second buffer member, it is possible to prevent the first bearing seat, the second bearing seat and the first support block from having a rigid collision, which is beneficial to protecting the bearings, extending the service life of the equipment, and also facilitating the adjustment of the height of the upper supporting roll and the upper intermediate roll;
[0018] Similarly, by providing the third buffer member and the fourth buffer member, it is possible to prevent the third bearing seat, the first guide rail and the second support block from having a rigid collision, extend the service life of the equipment, and at the same time facilitate the adjustment of the height of the work roll and the first guide rail.
[0019] In some embodiments, the roll changing mechanism further includes a third guide rail, a third receiving rail and a second roll changing power member. The third guide rail is built into the installation groove, the lower supporting roll is slidably connected to the third guide rail, the third receiving rail is arranged at the bottom of the roll changing frame, and the third receiving rail is docked with the third guide rail. The second roll changing power member is installed on the third receiving rail, and the output end of the second roll changing power member is connected to the lower supporting roll.
[0020] With the above technical solution, the third guide rail is docked with the third receiving rail, which facilitates the second roll-changing power member to pull the lower backup roll out of the installation groove or push the lower backup roll into the installation groove, facilitating the loading and unloading of the lower backup roll.
[0021] In some embodiments, the roll-changing mechanism further includes a second supporting rail assembly. The second supporting rail assembly includes a second supporting rail power member and a top block. The second supporting rail power member is installed on the frame. One end of the top block is connected to the output end of the second supporting rail power member, and the other end is connected to the third guide rail. The second supporting rail power member is used to drive the top block to lift the third guide rail to be flush with the third receiving rail.
[0022] With the above technical solution, during the leveling or embossing process, the third guide rail does not contact the lower backup roll. When it is necessary to load and unload the lower backup roll, the second supporting rail assembly lifts the third guide rail to be flush with the third receiving rail and makes the third guide rail contact the lower backup roll, so as to facilitate sliding the lower backup roll out of or into the installation groove.
[0023] In some embodiments, it further includes a coupling support mechanism arranged at one end of the lower backup roll away from the third receiving rail. The coupling support mechanism includes two oppositely arranged clamping blocks and a clamping power member for driving the two clamping blocks to approach or separate from each other.
[0024] With the above technical solution, when it is necessary to replace the lower backup roll, the clamping power member drives the two clamping blocks to approach each other to clamp and support the coupling, preventing the coupling from falling and causing accidents when replacing the lower backup roll. When precision processing or embossing the workpiece, the clamping power member drives the two clamping blocks to separate from each other to avoid interference between the clamping blocks and the coupling.
[0025] In some embodiments, a pressing cylinder is further arranged at the bottom of the frame. The pressing cylinder is used to drive the lower backup roll to lift and lower. Description of the Drawings

[0041] If Figure 1 and Figure 2 As shown in FIG. 1 , the roll-changing mechanism 30 includes a roll-changing frame 31 disposed on one side of the frame 10, a first guide rail 32 and a second guide rail 33 disposed in the mounting groove 11, a roll-changing slide 34 slidably connected to the roll-changing frame 31, and a first roll-changing power member 35 driving the roll-changing slide 34 to move. The working roll 23 is slidably connected to the first guide rail 32, a first receiving rail 311 docking with the first guide rail 32 is disposed on the roll-changing frame 31, the lower intermediate roll 24 is slidably connected to the second guide rail 33, a second receiving rail 312 docking with the first guide rail 32 is disposed on the roll-changing frame 31, a draw hook 341 is disposed on the roll-changing slide 34, and a draw ring 36 corresponding to the draw hook 341 is disposed on the working roll 23 and the lower intermediate roll 24. Optionally, the first roll-changing power member 35 is a gas cylinder or an oil cylinder, the cylinder body of the first roll-changing power member 35 is hinged to the roll-changing frame 31, and the telescopic rod is hinged to the roll-changing slide 34.
[0042] Further, the first guide rail 32 is installed on top of the first support block 12. A first guide wheel (not shown in the figure) corresponding to the first guide rail 32 is provided on the third bearing block 231. The second guide rail 33 is installed on top of the fifth bearing block 251. A second guide wheel (not shown in the figure) corresponding to the second guide rail 33 is provided on the fourth bearing block 241. By slidingly connecting the first guide wheel with the first guide rail 32 and the first receiving rail 311, and the second guide wheel with the second guide rail 33 and the second receiving rail 312, it is convenient to load and unload the working roll 23 and the lower intermediate roll 24.
[0043] Optionally, a first buffer member (not shown in the figure) and a second buffer member (not shown in the figure) are provided on the first support block 12. The first buffer member is used to support the first bearing block 211, and the second buffer member is used to support the second bearing block 221;
[0044] A third buffer member (not shown in the figure) and a fourth buffer member (not shown in the figure) are provided on the second support block 13. The third buffer member is used to support the first guide rail 32, and the fourth buffer member is used to support the third bearing block 231.
[0045] By providing the first buffer member and the second buffer member, it is possible to prevent the first bearing block 211 from rigidly colliding with the second bearing block 221 and the first support block 12, which is beneficial to protecting the bearings and extending the service life of the equipment. It also facilitates the adjustment of the height of the upper support roll 21 and the upper intermediate roll 22. Similarly, by providing the third buffer member and the fourth buffer member, it is possible to prevent the third bearing block 231 from rigidly colliding with the first guide rail 32 and the second support block 13, extend the service life of the equipment, and at the same time facilitate the adjustment of the height of the working roll 23 and the first guide rail 32.
[0046] Preferably, in this embodiment, the first buffer member, the second buffer member, the third buffer member, and the fourth buffer member are gas springs. In other embodiments, other elastic members that can achieve the same function can also be used, such as hydraulic cylinders, ejector rods with springs, or rubber columns, etc.
[0047] Please refer again to Figure 3 And Figure 4, since the second guide rail 33 is mounted on the fifth bearing block 251, when replacing the work roll 23 and the lower intermediate roll 24, in order to avoid interference between the lower intermediate roll 24 and the lower backup roll 25, the lower backup roll 25 will be lowered by a certain distance so that there is a certain spacing between the lower backup roll 25 and the lower intermediate roll 24. However, this will cause a height difference between the second guide rail 33 and the second receiving rail 312. In order to enable the roll change operation to proceed normally, the roll change mechanism 30 further includes a first rail support assembly 40. The first rail support assembly 40 includes a first rail support power member 41, a pull rod 42 and a support block 43. The first rail support power member 41 is installed on the frame 10, and the first rail support power member 41 is located on the side of the second guide rail 33. The pull rod 42 is connected to the output end of the first rail support power member 41. The support block 43 is rotatably connected to the pull rod 42. The first rail support power member 41 is used to drive the support block 43 to lift the second guide rail 33 to be flush with the second receiving rail 312. The first rail support power member 41 is used to drive the support block 43 to lift the second guide rail 33 to be flush with the second receiving rail 312, so that the lower intermediate roll 24 can smoothly enter and exit the frame 10 along the second guide rail 33 and the second receiving rail 312 for replacement. And the support block 43 is set to be rotatably connected to the pull rod 42, so that when not changing the roll, the support block 43 can be rotated by a certain angle to prevent the support block 43 from interfering with the lifting and lowering of the lower receiving roll.
[0048] In this embodiment, the first rail support power member 41 is a cylinder. In other embodiments, hydraulic cylinders or motors and other power components that can achieve the same function can also be used.
[0049] Preferably, in order to prevent the second guide rail 33 from shaking during the rail support process or the roll change process, a positioning pin is provided on the support block 43, and a pin hole for inserting the positioning pin is provided on the second guide rail 33. Similarly, the second guide rail 33 and the second receiving rail 312 are butt-jointed through a stepped head, and the two stepped heads are provided with a pin.
[0050] Further, in order to facilitate the replacement of the work roll 23 and the lower intermediate roll 24, no third card slots are provided on the third bearing block 231 and the fourth bearing block 241 far from the pull ring 36, that is, only the third bearing block 231 and the fourth bearing block 241 connected to the pull ring 36 are provided with third card slots corresponding to the first inner pressing plate and the second inner pressing plate. In this way, when replacing the work roll 23 and the lower intermediate roll 24, only the first inner pressing plate and the second inner pressing plate on the side close to the roll change frame 31 need to be disassembled, which can reduce the roll change process and improve the roll change efficiency.
[0051] As Figure 4As shown, the roll changing mechanism 30 of the five-roll finishing embossing machine 100 further includes a third guide rail 37, a third receiving rail 38, and a second roll changing power member 39. The third guide rail 37 is built into the installation groove 11. A third guide wheel (not labeled in the figure) corresponding to the third guide rail 37 is provided on the fifth bearing block 251. The lower support roll 25 is slidably connected to the third guide rail 37. The third receiving rail 38 is provided at the bottom of the roll changing frame 31, and the third receiving rail 38 is butted against the third guide rail 37. The second roll changing power member 39 is installed on the third receiving rail 38, and the output end of the second roll changing power member 39 is connected to the lower support roll 25. The docking of the third guide rail 37 and the third receiving rail 38 facilitates the second roll changing power member 39 to pull out the lower support roll 25 from the installation groove 11 or push the lower support roll 25 into the installation groove 11, facilitating the loading and unloading of the lower support roll 25. Optionally, the second roll changing power member 39 is a cylinder.
[0052] Further, the roll changing mechanism 30 further includes a second rail supporting assembly 50. The second rail supporting assembly 50 includes a second rail supporting power member 51 and a top block 52. The second rail supporting power member 51 is installed on the frame 10. One end of the top block 52 is connected to the output end of the second rail supporting power member 51, and the other end is connected to the third guide rail 37. The second rail supporting power member 51 is used to drive the top block 52 to lift the third guide rail 37 to be flush with the third receiving rail 38. During the flattening or embossing process, the third guide rail 37 does not contact the lower support roll 25. When it is necessary to load and unload the lower support roll 25, the second rail supporting assembly 50 lifts the third guide rail 37 to be flush with the third receiving rail 38 and makes the third guide rail 37 contact the lower support roll 25, so as to facilitate sliding the lower support roll 25 out of or into the installation groove 11.
[0053] In order to prevent the third guide rail 37 from shaking during the jacking process and the roll changing process and causing a safety accident, the third guide rail 37 is connected to the top block 52 through a positioning pin, and the third guide rail 37 and the third receiving rail 38 are butted through a stepped structure and are prevented from coming off by inserting a pin.
[0054] As Figure 2 shown, in order to prevent the coupling from falling when replacing the lower support roll 25, the five-roll finishing embossing machine 100 further includes a coupling supporting mechanism 60 provided at one end of the lower support roll 25 away from the third receiving rail 38. The coupling supporting mechanism 60 includes two oppositely arranged clamping blocks 61 and a clamping power member 62 for driving the two clamping blocks 61 to approach or separate from each other. When replacing the lower support roll 25, the clamping power member 62 drives the two clamping blocks 61 to approach each other to clamp and support the coupling, preventing the coupling from falling and causing an accident when replacing the lower support roll 25. When precision flattening or embossing the workpiece, the clamping power member 62 drives the two clamping blocks 61 to separate from each other to avoid interference between the clamping blocks 61 and the coupling.
[0055] For the five-roll finishing embossing machine 100 of the present application, when it is necessary to replace the working roll 23 and the lower intermediate roll 24, first lower the lower supporting roll 25 until it is separated from the lower intermediate roll 24. Then, dock the first guide rail 32 with the first receiving rail 311 and the second guide rail 33 with the second receiving rail 312. Next, the first roll-changing power component 35 drives the roll-changing slide 34 to slide towards the machine frame 10.
