Description

Technical Field

[0001] This utility model relates to the field of reducing mill technology, specifically to a roller box adjustment device for a reducing mill unit. Background Technology

[0002] A reducing mill is a widely used piece of equipment in the production of pipes and bars. Its main function is to further process pipes or bars that have already undergone preliminary rolling or drawing through a series of rollers to reduce their outer diameter and at the same time improve the dimensional accuracy and surface quality of the product.

[0003] The roller box of a reducing mill is a device that carries and drives the rolls. It typically includes important components such as rolls, bearings, sealing devices, and the roller box itself. The rolls bear enormous pressure and friction. Since adjacent stands of the reducing mill adopt a 45° top-to-bottom configuration, the roller box and the operating side are located on opposite sides of the mill, respectively. The operating side is convenient for adjusting the pressure material, and operators generally work on the operating side. The roller box allows for fine-tuning of the roll position and spacing to adapt to the processing requirements of different product specifications. In the rolling process of red steel, roughing is performed first, followed by intermediate rolling, with a slower rolling speed, known as the low-speed zone. The finishing mill reducing mill has a faster rolling speed, known as the high-speed zone.

[0004] However, in actual use, the existing roller box of the reducing mill unit is located on the back of the operating side. When it is necessary to adjust the roll gap, the workers have to go to the opposite side of the operating side to carry out the work. Since the rolling speed in the reducing mill unit area is high, the rolling line is very easy for red steel to jump out. Crossing the rolling line poses a great safety risk. Therefore, relevant national safety regulations clearly state that bridges must not be built in the high-speed area for people to cross. So, they can only detour through the low-speed area to cross the bridge. However, due to the long distance, the roll gap cannot be adjusted in time, which reduces work efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a roller box adjustment device for a reducing mill unit, so as to solve the problem that when the roller gap needs to be pressed during the use of the existing roller box of the reducing mill unit, it is necessary to bypass the low-speed zone and cross the bridge. Due to the long distance, the roller gap cannot be adjusted in time, resulting in reduced work efficiency.

[0006] To achieve the above objectives, the basic solution provided by this utility model is as follows: a roller box adjustment device for a reducing mill unit, comprising a reducing mill body, a first box, and a second box. A rotating rod is detachably connected to the adjustment end of the reducing mill body. One end of the rotating rod rotatably passes through the first box. A secondary bevel gear is provided on the rotating rod. Both the first and second boxes are connected to the reducing mill body. A rotating shaft is provided inside the first and second boxes, respectively. Rotating shafts are rotatably connected to the first and second shafts. There are two main bevel gears, namely main bevel gear 1 and main bevel gear 2, which mesh with secondary bevel gear 1. A rotating rod 2 passes through the housing 1 and housing 2, and secondary bevel gear 2 is provided at both ends of the rotating rod 2. Each secondary bevel gear 2 meshes with main bevel gear 1 and main bevel gear 2 respectively. A support seat is provided on one side of the reducing machine body, and a rotating rod 3 passes through the support seat and housing 2. A secondary bevel gear 3 is provided at one end of the rotating rod 3, and the secondary bevel gear 3 meshes with main bevel gear 2.

[0007] The working principle of this utility model is as follows: When it is necessary to adjust the adjusting end of the roller box of the reducing mill unit, the operator first clamps the rotating rod three with an auxiliary tool. The rotating rod three drives the secondary bevel gear three to rotate, the secondary bevel gear three drives the main bevel gear two to rotate, and the main bevel gear two drives the secondary bevel gear two at one end of the rotating rod two that meshes with it. As the secondary bevel gear two rotates, the rotating rod two also rotates. The secondary bevel gear two at one end of the rotating rod two drives the main bevel gear one to rotate. As the main bevel gear one rotates, the secondary bevel gear one that meshes with the main bevel gear one also rotates. The secondary bevel gear one drives the rotating rod one to rotate, and the rotating rod one drives the adjusting end of the roller box of the reducing mill unit to rotate, thereby achieving the purpose of adjusting the adjusting end of the roller box of the reducing mill unit without having to go around to the operating side.

[0008] The beneficial effects of this utility model are as follows: by setting an adjustment device on one side of the reducing mill unit, the operator does not need to detour through the low-speed zone to cross the bridge. The adjustment of the roller box can be completed by rotating the three rods on the operating side, which can adjust the roller gap in time, improve work efficiency, and at the same time improve the timeliness and safety of the adjustment process, and reduce the labor intensity and safety risks of the job.

[0009] Option 2, which is a preferred option of the basic option, is provided with a clamp on one side of the reducing machine body, and the rotating rod passes through the clamp; by setting the clamp, it is easy to limit the rotation of the rotating rod and prevent the rotating rod from rotating due to the vibration of the reducing machine.

[0010] Option 3, which is a preferred option of the basic option, has a steering wheel-style handle at one end of the rotating rod 3; by setting a steering wheel-style handle, it is convenient for the operator to control the direction and force of rotation.

[0011] Option 4, which is a preferred option of Option 3, has scale lines on the steering wheel handle and a pointer on the side of the reducing machine body near the steering wheel handle; the combination of scale lines and pointer facilitates precise control and adjustment, and the operator can accurately adjust the roller box to the required position according to the scale and pointer indications.

[0012] Option 5, which is a preferred option of the basic option, involves a bolt connecting the adjusting end of the reducing machine body to the rotating rod; the connection via a brush facilitates maintenance and replacement of the device.

[0013] Option 6, which is a preferred option of the basic option, is that both the first and second housings are equipped with inspection windows; by setting up inspection windows, it is convenient to inspect, repair and maintain the components inside the housings, thereby improving the service life of the equipment.

[0019] like Figures 1 to 3As shown: A roller box adjustment device for a reducing mill unit includes a reducing mill body 1, a first box 2, and a second box 3. A rotating rod 201 is bolted to the adjusting end 101 of the reducing mill body 1. One end of the rotating rod 201 rotatably passes through the first box 2. A secondary bevel gear 202 is fixedly connected to the rotating rod 201. The first box 2 and the second box 3 are both fixedly connected to the reducing mill body 1. A rotating shaft 203 and a rotating shaft 301 are fixedly connected inside the first box 2 and the second box 3, respectively. A main bevel gear 204 and a main bevel gear 302 are rotatably connected to the rotating shaft 203 and the rotating shaft 301, respectively. The main bevel gear 204 and the secondary bevel gear 202 mesh. A rotating rod 205 rotatably passes between the first box 2 and the second box 3. Both ends of the rotating rod 205 are fixedly connected to secondary bevel gears 202. 6. Each secondary bevel gear 206 meshes with the primary bevel gear 204 and the primary bevel gear 302 respectively. A support base 4 is fixedly connected to the side of the reducing machine body 1 adjacent to the adjusting end 101 of the reducing machine body 1. A rotating rod 303 rotatably passes between the support base 4 and the housing 2 3. A secondary bevel gear 304 is fixedly connected to one end of the rotating rod 303. The secondary bevel gear 304 meshes with the primary bevel gear 2 302. A clamp 5 is fixedly connected to one side of the reducing machine body 1. The rotating rod 303 passes through the clamp 5. A steering wheel-type handle 305 is provided at the end of the rotating rod 303 away from the secondary bevel gear 304. The steering wheel-type handle 304 is provided with scale lines. A pointer 306 is provided on the side of the reducing machine body 1 near the steering wheel-type handle 304. Both housing 1 2 and housing 2 3 are provided with inspection windows 6.

[0020] The implementation method of this embodiment is as follows: When it is necessary to adjust the adjusting end 101 of the roller box of the reducing mill unit, the operator first rotates the bolt on the clamp 5 to loosen the clamp 5, thereby putting the rotating rod 303 in an active state. Then, the operator records the position of the pointer 306 pointing to the scale line on the steering wheel handle 305. Next, the operator rotates the steering wheel handle 305, which drives the rotating rod 303 to rotate. The rotating rod 303 drives the secondary bevel gear 304 to rotate, which in turn drives the main bevel gear 202 to rotate. The main bevel gear 202 drives the secondary bevel gear 206 at one end of the rotating rod 205 that meshes with it. As the secondary bevel gear 206 rotates... Rotating rod 205 also rotates, and the secondary bevel gear 206 at one end of rotating rod 205 drives the main bevel gear 204 to rotate. As the main bevel gear 204 rotates, the secondary bevel gear 202 meshing with the main bevel gear 204 also rotates. The secondary bevel gear 202 drives rotating rod 201 to rotate, and rotating rod 201 drives the adjusting end 101 of the roller box of the reducing mill to rotate. The steering wheel handle 305 rotates 360° in both directions, which represents a roll gap of 0.4mm. This achieves the purpose of adjusting the adjusting end 101 of the roller box of the reducing mill without having to go around to the operating side. After the adjustment is completed, the operator tightens the bolts on the clamp 5 so that the clamp 5 clamps the rotating rod 303.
