Description

Technical Field

[0001] The utility model relates to the technical field of rolling mills, in particular to a main transmission flexible supporting structure of a rolling mill. Background Art

[0002] The rolling mill is mainly composed of rollers, frames, roll gap adjustment devices, roll temperature adjustment devices, transmission devices, lubrication systems, control systems and roll removal devices. The working principle of the rolling mill can be divided into two basic processes: pressing down and stretching. First, the metal material is fed into the feed port of the rolling mill after pretreatment and enters the working area between the upper and lower roll groups. Then, the rollers are driven to rotate through the transmission system, so that the metal material is gradually deformed under the extrusion of the rollers. In this process, the metal material will be squeezed and stretched by the rollers, thereby changing its cross-sectional shape and size.

[0003] During use, the rolling mill is generally rigidly connected in the frame. When extruding metal materials, if there are harder impurities adhering to the surface of the metal material and entering between the two rollers, due to the lack of buffering in the frame, it is easy to press grooves on the surface of the roller or the metal material, which can easily damage the roller.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] like Figure 1~Figure 4 As shown, this embodiment proposes a flexible support structure for the main transmission of a rolling mill, including: a frame 1, a roller 2, a supporting mechanism, a buffer mechanism, an adjusting mechanism and a driving mechanism. A sliding rod 13 is fixedly connected to the frame 1, a sliding hole is provided on the supporting frame 3, and the sliding rod 13 is slidably set in the sliding hole. A sliding groove is provided on the frame 1, and two guide bars 16 are fixedly connected in the sliding groove. Two movable grooves are provided on the slide plate 11, and the two guide bars 16 are respectively slidably set in the two movable grooves. Two rollers 2 are provided, and both rollers 2 are set in the frame 1. Through the cooperation among the frame 1, the roller 2, the supporting mechanism, the buffer mechanism, the adjusting mechanism and the driving mechanism, it is convenient to perform force buffering when the roller 2 is squeezed by harder impurities, thereby reducing the damage to the roller 2 caused by the harder impurities.

[0044] Among them, the supporting mechanism is arranged in the frame 1, which is used to support the roller 2 to rotate. The supporting mechanism includes: a supporting frame 3 and a spring 4. There are four supporting frames 3, and the four supporting frames 3 are all slidably arranged in the frame 1. The two rollers 2 are respectively rotatably arranged between each adjacent two supporting frames 3. There are four springs 4, and each adjacent two springs 4 are respectively fixedly connected between each adjacent two supporting frames 3. The adjusting mechanism is arranged on the frame 1, which is used to adjust the distance between the two rollers 2. The adjusting mechanism includes: a bidirectional screw 9 and a first motor 10. There are two bidirectional screws 9, and the two bidirectional screws 9 are rotatable. The two buffer frames 5 are each provided with two screw holes, and two bidirectional screw rods 9 are respectively threadedly connected between each two adjacent screw holes. Two first motors 10 are provided, and the two first motors 10 are both provided on the frame 1. The output ends of the two first motors 10 are respectively fixedly connected with the two bidirectional screw rods 9. Specifically, the bidirectional screw rods 9 are driven to rotate by the first motor 10. When the bidirectional screw rods 9 rotate, the two adjacent support frames 3 are driven to move relative to the two rollers 2. The two adjacent support frames 3 are supported by the spring 4, so that the spacing adjustment of the two rollers 2 is maintained synchronously.

[0045] Among them, there are two buffer mechanisms, both of which are arranged in the frame 1, and are used to flexibly buffer the roller 2. The buffer mechanism includes: a buffer frame 5, a slide 6, an elastic plate 7 and a support wheel 8. A support shaft 17 is fixedly connected in the slide 6, and the support wheel 8 is rotatably set on the support shaft 17. The two buffer frames 5 are fixedly connected to support ribs 15, and the two support ribs 15 are both arranged in an arc shape. Two limit rods 14 are fixedly connected to the slide 6. Two limit holes are provided on the buffer frame 5. The two limit rods 14 are respectively slidably set in the two limit holes. The buffer frame 5 is slidably set in the frame 1. The slide 6 is provided with two, and the two slides 6 The two rollers 2 are all slidably arranged on the buffer frame 5, and there are two groups of elastic plates 7. The two groups of elastic plates 7 are respectively fixedly connected to the two slides 6. The two slides 6 are rotatably connected to two support wheels 8, and multiple support wheels 8 are in contact with the roller 2. Specifically, when the two rollers 2 squeeze harder impurities, the rollers 2 are forced to move along the slide rod 13, and the slide 6 is driven to slide in the buffer frame 5 when the rollers 2 move. At this time, the buffer frame 5 squeezes the elastic plate, thereby absorbing the force of the roller 2 moving and when the impurities move out from between the two rollers 2, the roller 2 returns to its original position through the rebound of the elastic plate, thereby reducing the damage of the impurities to the roller 2.

[0046] Among them, the driving mechanism is arranged on the frame 1, which is used to drive the roller 2 to rotate. The driving mechanism includes: a slide plate 11 and a second motor 12. The slide plate 11 is slidably arranged in the slide groove, and the second motor 12 is arranged on the slide plate 11. The output end of the second motor 12 passes through the slide plate 11 and is fixedly connected to one of the rollers 2. Specifically, the roller 2 is driven to rotate by the second motor 12 arranged on the slide plate 11, so as to extrude the metal material.

[0047] In this embodiment, when the metal material is extruded, the bidirectional screw 9 is driven to rotate by the first motor 10. When the bidirectional screw 9 rotates, it drives the two adjacent support frames 3 to move relative to the two rollers 2. The two adjacent support frames 3 are supported by the spring 4, so that the two rollers 2 maintain synchronous spacing adjustment. The roller 2 is driven to rotate by the second motor 12 arranged on the slide plate 11, so as to extrude the metal material. When harder impurities adhere to the surface of the metal material during extrusion, the roller 2 is forced to move along the slide bar 13. When the roller 2 moves, it drives the slide 6 to slide in the buffer frame 5. At this time, the buffer frame 5 squeezes the elastic plate, thereby absorbing the force of the roller 2 moving and when the impurities move out from between the two rollers 2, the roller 2 returns to its original position through the rebound of the elastic plate, thereby reducing the damage of the impurities to the roller 2.
