Description

Technical Field

[0001] This utility model relates to the technical field of roller shaft assembly for plate rolling machines, and in particular to a roller shaft assembly for plate rolling machines that allows for quick roller replacement. Background Technology

[0002] A plate rolling machine is a metal sheet processing equipment that integrates advanced mechanical design, precise control technology, and a high-efficiency drive system.

[0003] Most of them use a large diameter roller to roll the plate, but this can only be used for rollers with the same wall thickness. As the application of roller rolling becomes more and more widespread, when two specifications of rolled plates with the same diameter but different wall thicknesses are required, it is necessary to readjust the spacing between the three rollers on the entire rolling machine. This is not only time-consuming and labor-intensive, but also means that the rolling and adjustment can no longer be performed at the same time.

[0004] The existing patent (publication number: CN212551146U) discloses a thin-walled plate rolling machine with adjustable roller diameter. The machine body includes an end shaft, and the inner wall of the end shaft is provided with a diameter-adjustable mechanism. This mechanism includes a disc, and the inner wall of the end shaft is fixedly sleeved with the outer surface of the disc. This thin-walled plate rolling machine with adjustable roller diameter achieves automatic adjustment of the distance between the upper roller and two lower rollers on the machine body when rolling two specifications of plates with the same diameter but different wall thicknesses. It also allows for simultaneous rolling and adjustment. Furthermore, by employing a differential connection method that connects the inlet and outlet pipes of the hydraulic cylinder, the machine facilitates the extension of the hydraulic cylinder piston rod without increasing the hydraulic pump flow, thus preventing any impact on the quality of the rolled plate.

[0005] To address the aforementioned issues, existing patents offer solutions, but these solutions have certain limitations in practice. When replacing rollers in the roller assembly of a plate rolling machine, it is often necessary to use machinery such as cranes for assistance. Due to the large weight of the rollers, they are prone to collisions with other components, requiring workers to continuously align and adjust the rollers on both sides. This is not only inefficient but also poses a certain degree of danger.

[0006] To address this, a roller assembly for a plate rolling machine with quick roller changes is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a roller assembly for a plate rolling machine that allows for quick roller replacement. This solves the problem that when replacing rollers in existing plate rolling machine roller assemblies, it is often necessary to use machinery such as cranes for assistance. Due to the large weight of the rollers, they are prone to collisions with other components. This requires workers to constantly align and adjust the rollers on both sides, which is not only inefficient but also poses certain dangers.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a roller assembly for a plate rolling machine with quick roller changing capability, comprising a unit, a protective cover provided on the right side of the unit, a roller, two mounting blocks and two fixing blocks provided on the top of the unit, two adjusting mechanisms provided at the bottom of the roller, and an auxiliary mechanism provided on the top of the mounting blocks;

The bottom of the limiting plate extends into the interior of the auxiliary slot and is slidably connected to the interior of the auxiliary slot. The top of the adjusting column is fixedly connected to the bottom of the alignment block. The surface of the adjusting column is slidably connected to the interior of the auxiliary slot. The auxiliary slot is opened on the top of the mounting block. The side of the fixing rod near the auxiliary slot passes through the adjusting column and extends into the interior of the limiting plate.

[0010] Preferably, the adjustment mechanism includes two adjustment blocks arranged on opposite sides of the mounting blocks. The top of the adjustment block is provided with a positioning groove, the bottom of the roller extends into the interior of the positioning groove and contacts the interior of the positioning groove, and a positioning plate is fixedly connected to the side of the adjustment block away from the mounting block.

[0026] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A roller assembly for a plate rolling machine with quick roller change capability includes a unit 1. A protective cover 4 is provided on the right side of the unit 1. A roller 8, two mounting blocks 3 and two fixing blocks 12 are provided on the top of the unit 1. Two adjusting mechanisms 6 are provided at the bottom of the roller 8. An auxiliary mechanism 2 is provided at the top of the mounting blocks 3.

[0029] The auxiliary mechanism 2 includes two alignment blocks 201, two limiting plates 202, two adjusting columns 203, two auxiliary grooves 204, and two fixing rods 205. The bottom of the alignment block 201 is fixedly connected to the top of the limiting plate 202. The bottom of the limiting plate 202 extends into the interior of the auxiliary groove 204 and is slidably connected to the interior of the auxiliary groove 204. The top of the adjusting column 203 is fixedly connected to the bottom of the alignment block 201. The surface of the adjusting column 203 is slidably connected to the interior of the auxiliary groove 204. The auxiliary groove 204 is opened on the top of the mounting block 3. The side of the fixing rod 205 near the auxiliary groove 204 passes through the adjusting column 203 and extends into the interior of the limiting plate 202.

[0030] In this embodiment: by making the surface of the adjusting column 203 slide in connection with the interior of the auxiliary groove 204, the adjusting column 203 can easily drive the aligning block 201 to move upward to a suitable position inside the auxiliary groove 204, thereby facilitating the movement of the aligning block 201 and the limiting plate 202, and thus facilitating the fixing rod 205 to fix the adjusting column 203 and the limiting plate 202. This allows the two aligning blocks 201 to be assisted in being positioned by the two limiting plates 202 during the replacement of the roller 8, thereby improving the efficiency of replacing the roller 8.

[0031] Specifically, such as Figure 2 , Figure 3 , Figure 5 As shown, the adjustment mechanism 6 includes two adjustment blocks 601 arranged on opposite sides of the mounting blocks 3. The top of the adjustment block 601 is provided with a positioning groove 602. The bottom of the roller 8 extends into the interior of the positioning groove 602 and contacts the interior of the positioning groove 602. A positioning plate 603 is fixedly connected to the side of the adjustment block 601 away from the mounting block 3.

[0032] Specifically, such as Figure 2 , Figure 5 As shown, support plates 606 are fixedly connected to the front and rear sides of unit 1. Two limiting posts 604 are slidably connected inside the support plate 606. The top of the limiting post 604 is fixedly connected to the bottom of the adjusting block 601.

[0033] Specifically, such as Figure 5As shown, two spring adjustment brackets 605 are fixedly connected to the top of the support plate 606, and the top of the spring adjustment brackets 605 is fixedly connected to the bottom of the adjustment block 601.

[0034] In this embodiment: by fixing the positioning plate 603 to the mounting block 3 on the side close to the mounting block 3, the adjusting block 601 can be conveniently positioned to limit the roller 8 through the positioning groove 602 and the positioning plate 603, and the spring adjusting frame 605 can limit the adjusting block 601, thereby facilitating the movement of the roller 8 through the positioning groove 602, achieving the effect of facilitating the movement of the roller 8.

[0035] Specifically, such as Figure 4 As shown, two protective pads 10 are provided on the top of the mounting block 3, and the side of the protective pad 10 near the aligning block 201 is fixedly connected to the aligning block 201.

[0036] Specifically, such as Figure 3 As shown, both the top of the mounting block 3 and the top of the fixing block 12 are provided with rotating grooves 7, and the side of the adjusting block 601 near the mounting block 3 is slidably connected to the mounting block 3.

[0037] In this embodiment: by fixing the protective pad 10 to the side of the aligning block 201 that is close to the aligning block 201, the aligning block 201 can easily protect the roller 8 through the protective pad 10. The two rotating grooves 7 are respectively opened on the top of the mounting block 3 and the top of the fixing block 12, so that the fixing block 12 can easily fix the roller 8 through the rotating grooves 7, thus achieving the effect of fixing the roller 8.

[0038] Specifically, such as Figure 2 , Figure 3 As shown, the unit 1 has two hydraulic columns 9 inside. The top of the telescopic end of the hydraulic column 9 is fixedly connected to the bottom of the mounting block 3. The fixing block 12 has four fixing bolts 11 inside.

[0039] Specifically, such as Figure 1 , Figure 2 As shown, a mounting base 5 is fixedly connected to the right side of unit 1, and the top of the mounting base 5 is fixedly connected to the bottom of the protective cover 4.

[0040] In this embodiment: by fixing the top of the telescopic end of the hydraulic column 9 to the bottom of the mounting block 3, the telescopic end of the hydraulic column 9 can be easily moved by the roller 8 through the mounting block 3, so that the top of the fixed seat 5 is fixedly connected to the bottom of the protective cover 4, thereby facilitating the protective cover 4 to protect the inside of the unit 1, achieving the effect of protecting the inside of the unit 1.

[0041] Working principle: When replacing the top roller 8, the hydraulic column 9 first moves the roller 8 upward to the top via the mounting block 3. The fixing block 12 is then removed via the fixing bolts 11, thus removing the limit on the roller 8 and facilitating its removal by the crane. This removes the limit on the adjusting block 601. Under the limit of the spring adjusting frame 605, the adjusting block 601 assists in moving the roller 8, preventing collisions with other components of the unit 1 during movement. Next, the adjusting column 203 moves the locating block 201 upward within the auxiliary groove 204 to a suitable position, facilitating the movement of the locating block 201 and the limiting plate 202. The limiting plate 202 then assists in limiting the locating block 201, thus facilitating the movement of the fixing rod 2. 05. Fix the adjusting column 203 to the limiting plate 202, and then move the replacement roller 8 to the top of the two adjusting blocks 601 by the crane. The adjusting blocks 601 limit the roller 8 through the positioning groove 602 and the positioning plate 603. During the downward movement of the roller 8, the two aligning blocks 201 can assist in limiting the roller 8 on the protective pad 10, thereby improving the efficiency of replacing the roller 8. This solves the problem that when replacing the roller 8 of the roller assembly of the plate rolling machine, it is often necessary to use cranes and other machinery for auxiliary replacement. Due to the large weight of the roller 8, it is easy to collide with other parts. It requires the staff to constantly align and adjust the roller 8 on both sides, which is not only inefficient but also dangerous.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
