Description
Technical Field
[0001] This utility model belongs to the technical field of rolling mill rolls, and in particular relates to a rolling mill roll structure with concave and convex steps. Background Technology
[0002] Rolling is a plastic forming process that applies pressure to a metal billet using rotating rolls, reducing its cross-section and increasing its length. It falls under the category of metal processing and is primarily used to produce metal materials such as profiles, plates, and pipes. Rolls, as indispensable components in the rolling process, create continuous plastic deformation of the metal through the relative rotation of two rolls, ultimately shaping the metal workpiece into the required form and size. They play a crucial role in the metal processing field. However, the following problems still exist in the use of mainstream rolling rolls currently on the market: Rolls are usually set as a single piece of the same size, and can only be used to extrude one workpiece at a time. If multiple workpieces of different models need to be processed, multiple rolls of different models are required, which increases the processing cost. Rolls are usually directly connected to the drive unit, which drives the rolls to rotate and extrude the workpiece. During long-term use, the roll surface will inevitably experience wear and other problems, which will interfere with the normal operation of the rolling process. At this time, the rolls need to be repaired or replaced, but the direct connection with the drive unit makes it difficult to disassemble the rolls. When a section of the roll is severely damaged, the entire roll needs to be replaced, which results in high repair costs.
[0003] To address these issues, we provide a stepped roll structure. Utility Model Content
[0004] The purpose of this utility model is to provide a concave-convex step-connected roll structure. By setting up an upper roll assembly, a lower roll assembly, a rotating assembly, and a connecting rod, it solves the problems that the roll can only process a single metal workpiece of a fixed model, is not easy to disassemble, and has high maintenance costs.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a stepped concave-convex connected roll structure, comprising an upper roll assembly, a lower roll assembly, and a rotating assembly; the upper roll assembly comprises five concave rolls arranged in a linear array, and the lower roll assembly comprises convex rolls arranged in a linear array below the five concave rolls. The degree of concavity of the concave rolls decreases from left to right, and the degree of convexity of the convex rolls decreases from left to right, and the roll surface of each concave roll is complementary to the roll surface of the convex roll below it. When multiple workpieces need to be rolled for different models, the workpiece is placed between concave and convex rollers that match its model. The upper and lower roller assemblies rotate relative to each other, applying pressure to the workpiece to cause it to deform. This allows multiple workpieces to be processed for different models simultaneously. Both ends of the upper roller assembly and the lower roller assembly are provided with rotating components. Each rotating component includes a turntable, and a rotating shaft is fixedly connected to the end of the turntable away from the upper roller assembly. The upper roller assembly and the lower roller assembly are respectively connected to the rotating assemblies at both ends. The end of the rotating shaft is connected to the drive device for transmission. When the upper roller assembly or the lower roller assembly needs to be repaired, it can be repaired simply by removing the upper roller assembly or the lower roller assembly from the rotating assembly.
[0006] Furthermore, both ends of the concave roller located on the left end are fixedly connected to connectors, the right ends of the remaining concave rollers are fixedly connected to connectors, and the left ends of the remaining concave rollers are provided with connecting grooves.
[0007] Furthermore, both ends of the convex roller located on the left end are fixedly connected to connectors, the right ends of the remaining convex rollers are fixedly connected to connectors, and the left ends of the remaining convex rollers are provided with connecting grooves.
[0008] Furthermore, the cross-sectional dimensions of the connector and the connecting groove are the same, and the connector and the adjacent connecting groove are inserted into each other; To assemble the upper roller assembly, insert the connectors on the concave roller into the connecting grooves located on the right side of the concave roller in sequence. To assemble the lower roller assembly, insert the connectors on the convex roller into the connecting grooves located on the right side of the convex roller in sequence.
[0009] Furthermore, a bolt in a ring array is threaded through the turntable located on the circumference of the rotating shaft, and the tail end of the bolt is screwed and fixed to the adjacent connecting piece. When maintenance is required on the upper or lower roller assembly, simply remove the corresponding bolt to disconnect the upper or lower roller assembly from the rotating assembly, and then repair or replace the damaged upper or lower roller assembly.
[0010] Furthermore, each of the concave rollers on both sides of the connector has a through-hole insertion slot. The five insertion slots on the same side of the connector are on the same straight line and are connected to an insertion rod. The right end of the insertion rod is fixedly connected to a fixing plate one. The right end of the fixing plate one is threaded with bolts two arranged in a ring array. The tail end of the bolts two is threaded to the concave roller on the right end. The left end of the insertion rod extends through the concave roller on the left end and is threaded to a fixing plate two. The left end of the fixing plate two is threaded with bolts two. The tail end of the bolts two is threaded to the concave roller on the left end. Insert the connector rod through the connector slots on the five concave rollers in sequence, and use bolt two to screw and fix the first fixing plate and the concave roller on the right end. Screw the other end of the connector rod to the second fixing plate, and use bolt two to screw and fix the second fixing plate and the concave roller on the left end. This completes the fixing of the upper roller assembly.
[0011] Furthermore, each of the convex rollers on both sides of the connector has a through-hole insertion slot. The five insertion slots on the same side of the connector are on the same straight line and are connected to a common insertion rod. The right end of the insertion rod is fixedly connected to a fixing plate one. The right end of the fixing plate one is threaded with bolts two arranged in a ring array. The tail end of the bolts two is threaded to the convex roller on the right end. The left end of the insertion rod extends through the convex roller on the left end and is threaded to a fixing plate two. The left end of the fixing plate two is threaded with bolts two. The tail end of the bolts two is threaded to the convex roller on the left end. Insert the connector rod through the connector slots on the five convex rollers in sequence, and use bolt two to screw and fix the fixing plate one and the convex roller on the right end. Screw the other end of the connector rod to the fixing plate two, and use bolt two to screw and fix the fixing plate two and the convex roller on the left end. This completes the fixing of the upper roller assembly.
[0012] Furthermore, both ends of the concave roller and the convex roller are fixedly connected with limiting rings, and the arc surface of the limiting ring on the concave roller is in contact with the arc surface of the limiting ring below it. The limiting ring restricts the position of the workpiece to prevent it from shifting during the rolling process.
[0013] This utility model has the following beneficial effects: This invention solves the problem that rolling mills can only process a single metal workpiece of a certain type by setting up an upper roller assembly and a lower roller assembly. When it is necessary to process a metal workpiece into different types, the workpiece is simply placed between the corresponding concave roller and convex roller. The concave roller and convex roller rotate relative to each other, applying pressure to the workpiece and causing it to deform to form a finished product. The stepped and continuous arrangement of multiple concave rollers and convex rollers allows for the simultaneous processing of different types of workpieces, achieving the goal of processing multiple different types of workpieces at the same time.
[0014] This invention solves the problem of difficult disassembly of the rolls by setting up a rotating component. The rotating shaft is connected to the drive device. When the drive device is started, the rotating shaft rotates, which drives the rolls to rotate. When the rolls are damaged, only one bolt needs to be removed to remove the rolls. After the rolls are repaired, the rolls and turntable are realigned and fixed with one bolt, and the workpiece rolling work can be resumed. This makes the maintenance and replacement of the rolls convenient and quick.
[0015] This invention solves the problem of high maintenance costs for rolls by setting up connectors, connecting grooves, insertion grooves, and insertion rods. When a concave or convex roll is damaged, the corresponding upper or lower roll assembly is first removed, then bolt two is removed, fixing plate two can be taken off, insertion rod is pulled out, the damaged concave or convex roll is removed for repair or replacement, and then reassembled to complete the roll repair, thus achieving the goal of saving costs.
[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1
[0029] Please see Figure 1 , Figure 2 This utility model is a concave-convex step-connected roller structure, including an upper roller assembly 1, a lower roller assembly 2, and a rotating assembly 3; the upper roller assembly 1 includes five concave rollers 101 arranged in a linear array, and the lower roller assembly 2 includes convex rollers 201 arranged in a linear array below the five concave rollers 101. The degree of concavity of the concave rollers 101 decreases from left to right, and the degree of convexity of the convex rollers 201 decreases from left to right. Moreover, the roller surface of each concave roller 101 is complementary to the roller surface of the convex roller 201 located below it. When a workpiece is placed between the concave roller 101 and the convex roller 201, the concave roller 101 and the convex roller 201 rotate relative to each other, which can compress the workpiece and cause it to deform. Since the degree of convexity of the convex roller 201 decreases from left to right, and the roller surface of each concave roller 101 is complementary to the roller surface of the convex roller 201 located below it, when multiple workpieces need to be rolled for different models, the workpiece is placed between the concave roller 101 and the convex roller 201 that match its model, and the upper roller assembly 1 and the lower roller assembly 2 rotate relative to each other, so that multiple workpieces can be processed for different models at the same time.
[0030] Among them, such as Figure 1-6 As shown, the concave roller 101 located on the left end has connectors 102 fixedly connected to both ends, the other concave rollers 101 have connectors 102 fixedly connected to their right ends, and the other concave rollers 101 have connecting grooves 103 on their left ends. The convex roller 201 located on the left end has connectors 102 fixedly connected to both ends, the other convex rollers 201 have connectors 102 fixedly connected to their right ends, and the other convex rollers 201 have connecting grooves 103 on their left ends. The connectors 102 and connecting grooves 103 have the same cross-sectional dimensions, and the connectors 102 and the connecting grooves 103 adjacent to them are inserted into each other. By sequentially inserting the connector 102 on the concave roller 101 into the connecting groove 103 located at its right end of the concave roller 101, the assembly of the upper roller assembly 1 can be completed. By sequentially inserting the connector 102 on the convex roller 201 into the connecting groove 103 located at its right end of the convex roller 201, the assembly of the lower roller assembly 2 can be completed. Rotating the concave rollers 101 located at both ends will cause the entire upper roller assembly 1 to rotate, and rotating the convex rollers 201 located at both ends will cause the entire lower roller assembly 2 to rotate.
[0031] Among them, such as Figure 1-6 As shown, both ends of the concave roller 101 and the convex roller 201 are fixedly connected to limit rings 4, and the arc surface of the limit ring 4 on the concave roller 101 is in contact with the arc surface of the limit ring 4 below it. The limiting ring 4 limits the position of the workpiece to prevent it from shifting during the rolling process.
[0032] The working principle of this embodiment is as follows: Before rolling, the upper roll assembly 1 and the lower roll assembly 2 are assembled. The connector 102 on the concave roll 101 is inserted into the connecting groove 103 in the concave roll 101 located at its right end to complete the assembly of the upper roll assembly 1. The connector 102 on the convex roll 201 is inserted into the connecting groove 103 in the convex roll 201 located at its right end to complete the assembly of the lower roll assembly 2. Rotating the concave rolls 101 at both ends will rotate the entire upper roll assembly 1. Rotating the convex rolls 201 at both ends will rotate the entire lower roll assembly 2. When multiple workpieces need to be rolled for different models, the workpiece is placed between the concave roll 101 and the convex roll 201 that match its model. The upper roll assembly 1 and the lower roll assembly 2 rotate relative to each other to realize the simultaneous processing of multiple workpieces for different models. During the rolling process, the limiting ring 4 limits the position of the workpiece to prevent the workpiece from shifting and causing the finished product to become deformed. Specific Implementation Example 2
[0033] Please see Figure 1-6 Based on the first specific embodiment, both ends of the upper roller assembly 1 and the lower roller assembly 2 are provided with rotating components 3. The rotating components 3 include a turntable 301, and the end of the turntable 301 away from the upper roller assembly 1 is fixedly connected to a rotating shaft 302.
[0034] Among them, such as Figure 1-6 As shown, a series of bolts 303 arranged in a ring array are threaded through the turntable 301 located on the circumference of the rotating shaft 302. The tail end of the bolt 303 is screwed and fixed to the adjacent connecting piece 102. The working principle of this embodiment is as follows: the upper roller assembly 1 and the lower roller assembly 2 are respectively fixed to the rotating assemblies 3 at both ends by bolts 303. When the upper roller assembly 1 or the lower roller assembly 2 needs to be repaired, simply remove the corresponding bolts 303 to disconnect the upper roller assembly 1 or the lower roller assembly 2 from the rotating assemblies 3. The damaged upper roller assembly 1 or the lower roller assembly 2 can be repaired or replaced. Each rotating shaft 302 is connected to a drive device. When all drive devices are started, the rotating shafts 302 at both ends of the upper roller assembly 1 rotate in the forward direction, and the rotating shafts 302 at both ends of the lower roller assembly 2 rotate in the reverse direction, thereby driving the upper roller assembly 1 to rotate and the lower roller assembly 2 to rotate in the reverse direction to perform rolling work.

The five insertion slots 104 on the same side of the connector 102 are on the same straight line and are all connected to an insertion rod 5.

The tail end of the bolts 503 is threaded to the convex roller 201 on the right end. The left end of the insertion rod 5 extends through the convex roller 201 on the left end and is threaded to a fixing disk 502. The left end of the fixing disk 502 is threaded with bolts 503. The tail end of the bolts 503 is threaded to the convex roller 201 on the left end. The operation process of this embodiment is as follows: Insert the connecting rod 5 sequentially through the five insertion slots 104 on the five concave rollers 101 from the right end of the upper roller assembly 1, and use bolt 2 503 to screw and fix the fixing plate 1 501 and the concave roller 101 on the right end. The other end of the connecting rod 5 extends out of the concave roller 101 on the left end and is screwed onto the fixing plate 2 502. Bolt 2 503 is then used to screw and fix the fixing plate 2 502 and the concave roller 101 on the left end, thus completing the fixation of the upper roller assembly 1. Then, insert the connecting rod 5 sequentially through the insertion slots 104 on the five convex rollers 201 from the right end of the upper roller assembly 1, and use bolt 2 503 to screw and fix the fixing plate 1 501 and the convex roller 201 on the right end. The other end of the connecting rod 5 extends out of the convex roller 201 on the left and is screwed onto the fixing plate 2 502. The fixing plate 2 502 and the convex roller 201 on the left are then screwed together using bolt 2 503 to fix them, thus completing the fixing of the upper roller assembly 1. When a concave roller 101 is damaged, the upper roller assembly 1 is first removed from the rotating assembly 3, and then bolt 2 503 and fixing plate 2 502 are removed. The connecting rod 5 can then be pulled out to remove the damaged concave roller 101 for repair. When a convex roller 201 is damaged, the lower roller assembly 2 is first removed from the rotating assembly 3, and then bolt 2 503 and fixing plate 2 502 are removed. The connecting rod 5 can then be pulled out to remove the damaged convex roller 201 for repair.
