Description

Technical Field

[0001] This utility model relates to the field of ground roller repair technology, specifically to a ground roller overlay welding machine tool. Background Technology

[0002] In the steel rolling production process, floor rollers are key transmission and support equipment connecting various processes, and are widely used in areas such as the heating furnace exit, before and after the rolling mill, cooling bed, and finishing line. Floor rollers operate under harsh conditions of high temperature, heavy load, and high friction for extended periods, making their surfaces prone to wear. Due to the long length and complex processes of steel rolling production lines, a single production line requires hundreds to thousands of floor rollers, and their performance directly affects production efficiency and product quality.

[0003] To address the problem of roller wear, the industry commonly employs welding overlay technology for repair, which involves restoring the roller's dimensions and performance by cladding a wear-resistant alloy layer. Current roller repair equipment typically involves clamping the roller onto a machine tool and rotating it. During the roller's rotation, a submerged arc welding machine, moving along the length of the roller, forms a covering layer on its surface.

[0004] In the existing welding process, the roller rotates, causing some flux to fall off along with the roller and mix into the welding slag produced during the welding process, contaminating the machine. This requires regular cleaning of the machine, and the excess flux and welding slag are discarded together, resulting in waste and increasing production costs. Utility Model Content

[0005] The purpose of this utility model is to provide a ground roller surfacing machine tool that can collect flux during the ground roller surfacing process, reduce pollution to the machine, facilitate flux recycling, and reduce waste.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a ground roller surfacing machine tool, including a rotary clamping machine tool and a submerged arc welding mechanism. The submerged arc welding mechanism includes a submerged arc welding machine and a movable seat. The movable seat is movably disposed on one side of the rotary clamping machine tool along its length direction. A slag collection assembly is provided on the side of the movable seat near the ground roller. The slag collection assembly includes a slag collection plate located below the submerged arc welding machine and cooperating with the ground roller.

[0007] A further improvement of this utility model is that the slag collecting plate includes a first side plate portion, a second side plate portion, and a bottom plate portion located between the first side plate portion and the second side plate portion, the first side plate portion and the bottom plate portion are fixedly connected, and the lower end of the second side plate portion is rotatably connected to the bottom plate portion and fixed by a locking member.

[0008] A further improvement of this utility model is that a slag collection frame is detachably connected to the upper part of the base plate, and a screen plate is detachably connected to the upper end of the slag collection frame.

[0009] A further improvement of this utility model is that the slag collection assembly further includes a bearing plate fixedly disposed on the side of the movable seat near the ground roller. The bearing plate is provided with a vibration generator and at least three elastic connectors. The slag collection plate is disposed on the upper end of the elastic connectors and contacts the vibration end of the vibration generator.

[0010] A further improvement of this utility model is that the locking component includes connecting strips rotatably disposed on both sides of the base plate, the connecting strips being located below the floor roller and one end of which is fixed to the second side plate by bolts.

[0011] A further improvement of this utility model is that the first side plate and the second side plate are inclined and the distance between their upper ends is greater than the distance between their lower ends.

[0012] A further improvement of this utility model is that the contact surfaces of the second side plate and the bottom plate are provided with mutually cooperating abutting surfaces.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model, by setting a slag collection component that moves along with the moving seat of the submerged arc welding mechanism, can collect the flux during the ground roller welding process, reduce the pollution of the machine, facilitate the recycling of the flux, and reduce waste.

[0015] The slag collection component of this invention is fixed on the moving base. When the submerged arc welding machine moves, the slag collection component also moves synchronously, which can always recover the welding slag and flux generated during welding. Therefore, the slag collection frame does not need to be set for a long section along the length of the machine tool, which occupies little space. The collected flux and welding slag are concentrated in the shorter slag collection frame, making the collection more concentrated.

[0016] This invention uses a vibration generator to drive the slag collection plate to vibrate, and the filter screen can screen out larger welding slag, allowing the flux to continue falling. It can screen the welding machine and welding slag according to size, which is convenient for later recycling.

[0017] This invention, by providing a first side plate and a second side plate, can block the flux thrown out during the rotation of the ground roller. The blocked flux can then flow along the first and second side plates into the slag collection frame, further reducing environmental pollution and improving collection efficiency.

[0018] The second side plate of this utility model is rotatably connected to the bottom plate and fixed by a connecting strip. The second side plate can be lowered as needed, which is highly flexible. For example, when placing or removing the floor roller, lowering the second side plate can avoid it interfering with the operation. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1: Combination Figures 1-4 It is known that a ground roller surfacing machine tool includes a rotary clamping machine tool 1 and a submerged arc welding mechanism. The submerged arc welding mechanism includes a submerged arc welding machine 2 and a movable seat 3. The movable seat 3 is movably disposed on one side of the rotary clamping machine tool 1 along its length direction. A slag collection assembly is provided on the side of the movable seat 3 near the ground roller. The slag collection assembly includes a slag collection plate 4 located below the submerged arc welding machine 2 and cooperating with the ground roller.

[0026] The slag collection plate 4 includes a first side plate portion 5, a second side plate portion 6 disposed on both sides of the ground roller, and a bottom plate portion 7 located between the first side plate portion 5 and the second side plate portion 6. The first side plate portion 5 is fixedly connected to the bottom plate portion 7, and the lower end of the second side plate portion 6 is rotatably connected to the bottom plate portion 7 and fixed by a locking member. The first side plate portion 5 and the bottom plate portion 7 are fixedly connected.

[0027] A slag collection frame 8 is detachably connected to the top of the base plate 7, and a screen plate 9 is detachably connected to the upper end of the slag collection frame 8. Preferably, side plates are provided on both sides of the base plate 7, and the side walls of the slag collection frame 8 are fixed to the side plates with bolts. The side plates can also be used to position the slag collection frame 8 to ensure accurate placement. Preferably, the screen plate 9 includes a screen frame and a screen disposed within the screen frame. At least two support blocks are provided on the inner wall of the slag collection frame, and screw holes are provided through the screen frame. The screen frame is fixed to the support blocks with bolts. Preferably, a guide surface is provided at the upper end of the frame wall of the slag collection frame 8 to prevent flux from accumulating at the upper end of the frame wall.

[0028] The slag collection assembly further includes a support plate 10 fixedly disposed on the side of the movable seat 3 near the ground roller. The support plate 10 is equipped with a vibration generator 11 and at least three elastic connecting members 12. The slag collection plate 4 is disposed on the upper end of the elastic connecting members 12 and contacts the vibrating end of the vibration generator 11. The support plate 10 is provided with at least two connecting blocks, which are fixed to the side of the movable seat 3 by bolts. Preferably, the elastic connecting members are springs, with six springs arranged in a ring, and the vibration generator 11 is located between the six springs. The vibration generator 11 is a conventional vibration generator for screening in the prior art.

[0029] The locking mechanism includes connecting strips 13 rotatably disposed on both sides of the base plate 7. The connecting strips 13 are located below the floor roller, and one end of each strip is fixed to the second side plate 6 by bolts. The other end of each connecting strip 13 is rotatably connected to the side of the base plate 7 via a pivot.

[0030] The first side plate 5 and the second side plate 6 are inclined, and the distance between their upper ends is greater than the distance between their lower ends. The inclined arrangement can guide the flux and increase the collection area.

[0031] The contact surfaces of the second side plate 6 and the bottom plate 7 are provided with mutually mating abutting surfaces. The abutting surfaces of the two can also limit the rotation of the second side plate 6, preventing it from rotating excessively in the direction of the first side plate 5.

[0032] The working principle of Embodiment 1 of the ground roller surfacing machine provided by the utility model is as follows: When clamping the ground roller, firstly, the locking of the second side plate 6 is released by the connecting strip 13, and the second side plate 6 is lowered to avoid interference with the clamping. Then, the ground roller is installed on the rotary clamping machine tool 1, and the second side plate 6 is reset and fixed. The rotary clamping machine tool 1 is started to drive the ground roller to rotate, and the submerged arc welding mechanism is started. The submerged arc welding machine performs surfacing welding on the surface of the ground roller as the moving seat 3 moves. During surfacing welding, the flux and slag that fall fall along the first side plate 5 and the second side plate 6 onto the slag collection frame 8. Since the length of the slag collection frame of this utility model is relatively short, there will be a situation where the accumulation is too high. The flux and slag can be vibrated by starting the vibration generator 11 to distribute them on the screen plate 9, and the small particles of flux fall to achieve screening, which is convenient for subsequent recycling.
