Description

Technical Field

[0001] The utility model relates to the technical field of cold rolling heat treatment, in particular to a horizontal tension release device for silicon steel and a silicon steel annealing furnace production system. Background Art

[0002] At present, there are tension release devices in the continuous heat treatment lines of silicon steel in the metallurgical industry. In the heat treatment lines of low, medium and high grade non-oriented silicon steel and oriented silicon steel, horizontal annealing furnaces are used. Tension release devices need to be installed at the entrance and exit of the annealing furnace. Therefore, the supporting tension release device also adopts a vertical structure.

[0003] However, some annealing furnaces now adopt a vertical structure, which requires a horizontal tension release device with a small number of rollers, so that the deviation correction roller can be set close to the annealing furnace, thereby improving the quality of the strip. Therefore, it is necessary to design a tension release device with a small number of rollers. In addition, because some existing ones adopt cylinder drive, the cylinder output rod and the strip tension are on the same axis in this drive mode, which easily causes the cylinder output shaft to receive bending moment, resulting in a short life.

In addition, the terms "first", "second" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0024] The utility model provides a horizontal tension release device for silicon steel.

[0025] Reference Figure 1 and Figure 2 In this preferred embodiment, a horizontal tension release device for silicon steel includes a frame 1, a moving frame 2, a steering roller 4, a first linear guide rail 3 and a cylinder 5, wherein:

[0026] The movable frame 2 is installed on the frame 1 through the first linear guide rail 3, the cylinder 5 is fixed on the side of the frame 1, a steering roller 4 is supported on the movable frame 2, and the output rod of the cylinder 5 and the movable frame 2 are rotationally connected in a spherical contact manner to drive the movable frame 2 to slide relative to the frame 1.

[0027] Specifically, in this embodiment, a groove is opened on the side of the movable frame 2, a spherical pressure head 8 is fixed inside the groove, a spherical push head 7 is fixedly sleeved on the free end of the output rod of the cylinder 5, the spherical push head 7 is inserted into the groove and in spherical contact with the spherical pressure head 8, and the spherical push head 7 is located on the outer side of the groove and is covered with a push head pressure plate 6.

[0028] Further, the push head pressing plate 6 is detachably connected to the mobile frame 2 by fasteners, so as to facilitate the maintenance and installation of the spherical push head 7 and the spherical pressure head 8. The push head pressing plate 6 is sleeved on the outer side of the output rod of the cylinder 5 and its bottom abuts against the side of the spherical push head 7 and the mobile frame 2.

[0029] Furthermore, the movable frame 2 is also provided with a deviation correction mechanism for adjusting the running direction angle of the steering roller 4 .

[0030] This embodiment proposes a specific structure of a correction mechanism: the correction mechanism includes a correction hydraulic cylinder 9 installed on the mobile frame 2, the output roller of the correction hydraulic cylinder 9 is hinged to the bearing seat 10 of the steering roller 4, and the cylinder body of the correction hydraulic cylinder 9 is fixed on the mobile frame 2.

[0031] Specifically, the bearing seat 10 of the steering roller 4 is installed on the second linear guide rail 11 on the moving frame 2 , and the deviation correction hydraulic cylinder 9 drives the bearing seat 10 to slide relative to the second linear guide rail 11 .

[0032] In this embodiment, the installation height of the axis of the output shaft of the deviation correcting hydraulic cylinder 9 is lower than the height of the axis of the output rod of the cylinder 5 .

[0033] The working process of the horizontal tension release device for silicon steel is as follows: the maximum extension position of the output shaft of the cylinder 5 is the working position of the tension release device. When the tension of the strip needs to be released, the cylinder 5 is quickly retracted, and the steering roller 4 returns from the working position to the tension release position to avoid the strip breaking in the furnace. When the steering roller 4 is in the working position, the rod cavity of the cylinder 5 is not stressed, and the length of the strip released when the tension is released is twice the stroke of the cylinder 5.

[0034] The horizontal tension release device for silicon steel proposed by the utility model uses a steering roller 4 in combination with the running track of the strip steel to release the tension of the strip steel. Compared with the multi-roller structure in the prior art, after adopting the tension release device, the deviation correction roller can be set closer to the annealing furnace 15, reducing the difficulty of tension control. In addition, the output rod of the cylinder 5 and the moving frame 2 are rotatably connected in a spherical contact manner, which can effectively avoid the cylinder 5 lever from being subjected to bending moment, thereby increasing the service life of the cylinder 5.

[0035] The utility model further provides a silicon steel annealing furnace production system.

[0036] Reference Figure 3The silicon steel annealing furnace production system proposed in the utility model comprises an annealing furnace 15, a furnace front tension roller 12, a furnace front tension release device 13 and a furnace front deviation correction roller 14 which are sequentially arranged at the entrance side of the annealing furnace 15, and a furnace rear deviation correction roller 16, a furnace rear tension release device 17 and a furnace rear tension roller 18 which are sequentially arranged at the exit side of the annealing furnace 15, wherein the furnace front tension release device 13 and the furnace rear tension release device 17 both adopt the above-mentioned horizontal tension release device for silicon steel, and the furnace front deviation correction roller 14 and the furnace rear deviation correction roller 16 are respectively located at the entrance side and the exit side of the annealing furnace 15.

[0037] Furthermore, a tension meter is provided below the roller bearing seat 10 of the rear-furnace deviation-correcting roller 16 to integrate the function of a tension meter roller.

[0038] Because the tension meter is directly arranged below the roller bearing seat 10 of the correction roller 14 in front of the furnace, that is, the correction roller integrates the function of the tension roller. Compared with the existing tension roller that is separately arranged behind the correction roller, with such an arrangement, the tension meter is very close to the annealing furnace 15 (without an additional correction roller), so its tension measurement is accurate, which facilitates stable control of the tension of silicon steel, thereby improving the quality of the finished product of silicon steel strip. At the same time, the tension control device of the annealing furnace 15 also has the advantages of simple structure, stable and reliable operation, and easy implementation.

[0039] The silicon steel annealing furnace production system proposed by the utility model adopts this horizontal tension release device, and the width of the tension release device can be greatly reduced compared with the three rollers in the prior art. Therefore, the tension meter can be close to the annealing furnace 15, which is also beneficial to the tension measurement.

[0040] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
