Description

Technical Field

[0001] This utility model belongs to the field of continuous casting roll processing technology, and specifically relates to a tooling for welding continuous casting rolls. Background Technology

[0002] Continuous casting rolls are key components in continuous casting production. They are subjected to high temperature, high pressure and wear conditions for a long time. Therefore, wear-resistant and high temperature-resistant alloy layers need to be fused onto their surface through welding technology to extend their service life.

[0003] When overlaying the end faces of the continuous casting roll, the cladding metal has high fluidity and tends to flow outward from the end face of the roll body during the overlaying process. On the one hand, this can easily lead to a large waste of cladding metal and increase processing costs. On the other hand, the outflowing cladding metal can cause irregular weld formation at both ends of the continuous casting roll, resulting in defects such as incomplete fusion and undercut, which seriously affects the welding quality at both ends and can easily shorten the actual service life of the continuous casting roll.

[0004] Therefore, when performing overlay welding on both ends of a continuous casting roll, in order to reduce the waste of cladding metal and ensure the relative regularity of the cladding metal formation, a tooling for overlay welding of the continuous casting roll is needed to solve the existing problems. Utility Model Content

[0005] This invention can reduce the overflow of cladding metal from the end face of the continuous casting roll, reduce the waste of cladding metal, ensure the relative regularity of the cladding metal formation, and improve the welding quality.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a tooling for welding continuous casting rolls, including a support base, a support leg at the bottom of the support base, a continuous casting roll placed on the support base, and a frustum baffle fitted at both ends of the continuous casting roll. That is, when welding the two ends of the continuous casting roll, the frustum baffle can limit the cladding metal. The frustum baffle is made of copper, and the vertical section of the frustum baffle is a T-shaped two-stage frustum. The copper frustum baffle is not easy to fuse with the stainless steel cladding metal, and therefore will not stick to the cladding metal during the welding process, making it easy to disassemble and reuse. A support rod is coaxially fitted on the frustum baffle, and a limiting block for abutting and fixing the frustum baffle is fitted on the support rod. That is, the support rod and the limiting block are used together to provide stable support and fixation for the frustum baffle.

[0007] Optionally, both ends of the support rod are connected to threaded rods, and nuts are installed on the threaded rods for abutting and fixing the limiting block, that is, the nuts can be displaced on the threaded rods to abut the support rod.

[0008] Optionally, threaded grooves are provided at both ends of the support rod. The threaded grooves are coaxial with the support rod, and bolts are installed in the threaded grooves to prevent the nuts from slipping out.

[0009] Optionally, a fixing assembly for stabilizing the continuous casting roll is installed on the support base. The fixing assembly includes two telescopic cylinders symmetrically installed at the bottom of the support base. A base plate is connected to the output shaft of the telescopic cylinders. A sliding rod is installed on the base plate, penetrating the bottom of the support base. An arc-shaped plate for abutting against the continuous casting roll is installed on the sliding rod. A rubber pad is installed on the arc-shaped plate. That is, the telescopic cylinder can drive the arc-shaped plate, the base plate and the sliding rod to move vertically. The rubber pad on the arc-shaped plate can abut against the outer surface of the continuous casting roll for effective fixing of the continuous casting roll.

[0010] Optionally, a compression spring is installed on the base plate and support seat. The compression spring is arranged around the sliding rod, so that the compression spring can play a buffering role when the telescopic cylinder drives the arc plate to move upward.

[0011] Optionally, a rotating wheel for driving the continuous casting roll to rotate is installed on the support base. The rotating wheel is configured as a wheel brake, that is, the rotating wheel can drive the continuous casting roll to rotate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By setting up a frustum baffle, which is made of copper and designed as a T-shaped two-stage frustum, the continuous casting roll end faces can be better fitted to the shape of the continuous casting roll end faces during welding. This effectively blocks the cladding metal, reduces its overflow from the continuous casting roll end faces, reduces cladding metal waste, ensures the relative regularity of the cladding metal formation, and improves welding quality. At the same time, the copper material does not easily fuse with the stainless steel cladding metal, making it easy to disassemble and reuse.

[0013] 2. By cooperating with the support rod and the limiting block, the frustum baffle can be stably supported, preventing the frustum baffle from shifting during the welding process and ensuring that it continues to perform its blocking and limiting function.

[0014] 3. The support rod is connected to threaded rods and nuts are installed at both ends, and threaded grooves are opened to install bolts, which facilitates the disassembly and assembly of various components. The bolt diameter is smaller than the inner diameter of the continuous casting roll, which makes it easy to pick up and put down the continuous casting roll.

[0015] 4. The telescopic cylinder in the fixing assembly drives the arc plate, base plate, and sliding rod to move vertically. The rubber pad on the arc plate abuts against the outer surface of the continuous casting roll, effectively fixing the continuous casting roll and preventing it from moving or shaking during welding. The compression springs installed on the base plate and support seat provide cushioning and assistance when the telescopic cylinder moves the arc plate, protecting the surface of the continuous casting roll.

[0019] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0020] like Figure 1-3 As shown, a tooling for welding a continuous casting roll includes a support base 1, a continuous casting roll 12, a welding clamping assembly 2, and a fixing assembly 3. The continuous casting roll 12 is placed on the support base 1, and the welding clamping assembly 2 is sleeved and installed on the continuous casting roll 12. When welding on the end face of the continuous casting roll 12, it can reduce the overflow of molten metal and make the shape of the molten metal relatively regular. The fixing assembly 3 is installed on the support base 1 to stabilize the continuous casting roll 12 and prevent the continuous casting roll 12 from moving or shaking during the welding process.

[0021] like Figure 2As shown, the welding clamping assembly 2 includes a frustum baffle 21, a support rod 22, and a limiting block 23. Both ends of the continuous casting roll 12 are fitted with frustum baffles 21. When welding the two ends of the continuous casting roll 12, the frustum baffles 21 can limit the cladding metal. The frustum baffles 21 are made of copper and have a T-shaped two-stage frustum in their vertical cross section. The copper frustum baffles 21 are not easily fused with the stainless steel cladding metal, so they will not stick to the cladding metal during the welding process, making them easy to disassemble and reuse. The smaller frustum is fitted into the inner hole of the continuous casting roll 12, and the inner side of the larger frustum abuts against the end face of the continuous casting roll 12. The small end of the frustum baffles 21 faces the end face of the continuous casting roll 12. This design can better fit the shape of the end face of the continuous casting roll 12, which can enhance the blocking effect on the cladding metal, effectively reduce the overflow of the cladding metal from the end face of the continuous casting roll 12, thereby reducing the waste of cladding metal, ensuring the relative regularity of the cladding metal formation, and improving the welding quality. A support rod 22 is coaxially mounted on the frustum baffle 21. A limiting block 23 for abutting and fixing the frustum baffle 21 is mounted on the support rod 22. The support rod 22 and the limiting block 23 work together to provide stable support and fixation for the frustum baffle 21, preventing displacement of the frustum baffle 21 during welding and ensuring that it always remains in the correct position so as to continuously perform the function of blocking and limiting the molten metal.

[0022] like Figure 2 As shown, the welding clamping assembly 2 also includes a threaded rod 24, a nut 25, a threaded groove 26, and a bolt 27. Both ends of the support rod 22 are connected to threaded rods 24, and nuts 25 are installed on the threaded rods 24 for abutting and fixing the limiting block 23. That is, the nuts 25 can move on the threaded rods 24 to abut against the support rod 22. Both ends of the support rod 22 have threaded grooves 26, which are coaxially arranged with the support rod 22. Bolts 27 are installed in the threaded grooves 26, which prevent the nuts 25 from slipping off. The bolts 27 facilitate the disassembly of the nuts 25, the support rod 22, and the frustum baffle 21. The diameter of the bolts 27 is smaller than the inner diameter of the continuous casting roll 12, facilitating the placement and removal of the continuous casting roll 12.

[0023] like Figure 1As shown, the fixing component 3 includes a telescopic cylinder 31, a base plate 32, a sliding rod 33, an arc plate 34, a rubber pad 35, and a compression spring 36. Two telescopic cylinders 31 are symmetrically installed at the bottom of the support base 1, distributed along the axial direction of the continuous casting roll 12. A base plate 32 is connected to the output shaft of each telescopic cylinder 31. Three sliding rods 33 are installed on the base plate 32, penetrating the bottom of the support base 1. The telescopic cylinders 31 and sliding rods 33 are alternately distributed. An arc-shaped plate 34 is installed on each sliding rod 33 for contact with the continuous casting roll 12. A rubber pad 35 is installed on the arc-shaped plate 34. The telescopic cylinders 31 can vertically displace the arc-shaped plate 34, the base plate 32, and the sliding rods 33. The rubber pad 35 on the arc-shaped plate 34 can contact the outer surface of the continuous casting roll 12, effectively fixing the continuous casting roll 12 and preventing it from moving or shaking during the welding process, ensuring the accuracy and stability of the welding operation. The rubber pad 35 not only increases the friction between the rubber pad and the continuous casting roll 12 but also provides good cushioning, reducing potential damage to the continuous casting roll 12 caused by vibration.

[0024] Compression springs 36 are installed on the base plate 32 and the support seat 1. The compression springs 36 are arranged around the sliding rod 33. That is, the compression springs 36 can play a buffering role when the telescopic cylinder 31 drives the arc plate 34 to move upward, reducing the hard collision between the arc plate 34 and the continuous casting roll 12, thereby protecting the surface of the continuous casting roll 12 from damage. At the same time, when the telescopic cylinder 31 drives the arc plate 34 to move downward, the compression springs 36 can also provide a certain assistance, so that the arc plate 34 separates from the continuous casting roll 12 more smoothly.

[0025] like Figure 3 As shown, the support base 1 is equipped with support legs 11 and rotating wheels 13. The support legs 11 are vertically arranged at the bottom of the support base 1, and the rotating wheels 13 are installed on the support base 1 to drive the continuous casting roll 12 to rotate. The rotating wheels 13 are configured as rotating wheels with wheel brakes, that is, the rotating wheels 13 can drive the continuous casting roll 12 to rotate. When the arc plate 34 is no longer in contact with the continuous casting roll 12, the rotational force is applied to the continuous casting roll 12 under the action of the caster wheels, which can easily realize the rotation of the continuous casting roll 12.

[0026] Working principle: When using this continuous casting roll welding fixture, first place the continuous casting roll 12 on the support base 1. Then, start the telescopic cylinder 31. The telescopic cylinder 31 drives the base plate 32, sliding rod 33 and arc plate 34 to move upward. The rubber pad 35 on the arc plate 34 gradually comes into contact with the outer surface of the continuous casting roll 12, thereby fixing the continuous casting roll 12 and preventing the continuous casting roll 12 from moving or shaking during the subsequent welding process.

[0027] Then, the support rod 22 is fitted onto the continuous casting roll 12, and the frustum baffle 21 is fitted onto both ends of the continuous casting roll 12. The frustum baffle 21 is used to fix the support rod 22 and the continuous casting roll 12. At this time, the support rod 22, the frustum baffle 21 and the continuous casting roll 12 are coaxial. The limiting block 23 is fitted onto the support rod 22, the nut 25 is screwed onto the threaded rod 24, and the bolt 27 is installed in the threaded groove 26. Finally, when performing overlay welding on both ends of the continuous casting roll 12, the distance between the frustum baffle 21 and the continuous casting roll 12 can be adjusted by rotating the nut 25 appropriately according to the actual situation. This can reduce the direct overflow of cladding metal from the end face of the continuous casting roll 12, reduce the waste of cladding metal, ensure the relative regularity of the cladding metal formation, and improve the welding quality.

[0028] When it is necessary to rotate the continuous casting roll 12 for welding at different positions, first release the wheel brake, so that the arc plate 34 in the fixing assembly 3 is away from the surface of the continuous casting roll 12. Under the action of the caster wheel, a rotational force is applied to the continuous casting roll 12. The rotating wheel 13 drives the continuous casting roll 12 to rotate easily. After rotating to the appropriate position, lock the wheel brake, so that the rubber pad 35 on the arc plate 34 abuts against the surface of the continuous casting roll 12, and continue the welding work until the welding is completed.

[0029] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
