Abstract
The utility model discloses a kind of follow-on milling train uncoiling and batch breathing cantilever support axle, relate to the back shaft on milling train, technical scheme comprises back shaft and the contiguous block with back shaft matched together, improvements are, a junction of the edges of two sheets of paper pin running through axle head axis is provided with at described back shaft axle head and contiguous block link position place, described junction of the edges of two sheets of paper pin is along the uniform arrangement of axle head circumference, and described junction of the edges of two sheets of paper pin diameter is ￠ 25mm; The utility model, on the basis of original back shaft and contiguous block connected mode, is evenly squeezed into the junction of the edges of two sheets of paper pin of 4 diameter 25mm, is increased its anti-shear ability, effectively prevent junction fracture at the junction circumferencial direction of back shaft and contiguous block; Through the use of nearly 2 years; the back shaft of this structure meets need of production completely; there is not the equipment fault that back shaft and contiguous block rupture again; greatly reduce the labour intensity of downtime and workman; also save material and maintenance cost simultaneously, save spare part processing and fabricating expense and just reach about 16.5 ten thousand.
Description
Technical field
The utility model relates to a kind of back shaft, particularly relates to the uncoiling of a kind of modified milling train and batches breathing cantilever support axle.
Background technology
Milling train uncoiling/batch breathing cantilever support axle plays a part to support coil weight and uncoiling tension protection unwinding shaft in the operation of rolling.Because it bears larger shearing force in the operation of rolling, thus occur that back shaft and contiguous block rupture, shown in junction (3) as shown in Figure 1, cause cold-rolling mill uncoiling/batch expanding shaft to lose the strong point and the situation that cannot use.Because equipment is all introduced from external at present, the delivery cycle of its back shaft is long, costly, has a strong impact on normal production.
Utility model content
The utility model, in order to overcome the deficiencies in the prior art, proposes a kind of follow-on cantilever support axle, can effectively reduce the generation of back shaft fracture accident, extends the service life of back shaft.
The utility model is achieved through the following technical solutions:
Breathing cantilever support axle is batched in a kind of follow-on milling train uncoiling, comprise back shaft (1) and the contiguous block (2) with back shaft (1) matched together, improvements are, at described back shaft (1) axle head (10), contiguous block (2) link position place is provided with 4 and runs through the axial junction of the edges of two sheets of paper pin (4) of axle head (10), described junction of the edges of two sheets of paper pin (4) is along the circumferential uniform arrangement of axle head (10), and described junction of the edges of two sheets of paper pin (4) diameter is ￠ 25mm.
Owing to have employed said structure, the utility model compared with prior art, there is following beneficial effect: the utility model is on the basis of original back shaft and contiguous block connected mode, the junction of the edges of two sheets of paper pin of 4 diameter 25mm is evenly squeezed at the junction circumferencial direction of back shaft and chassis contiguous block, increase its anti-shear ability, prevent junction from rupturing; Through the use of nearly 4 years; the back shaft of this structure meets need of production completely; there is not the equipment fault that back shaft and contiguous block rupture again; greatly reduce the labour intensity of downtime and workman; also save material and maintenance cost simultaneously, only within 4 years, save spare part processing and fabricating expense and just reach about 16.5 ten thousand.
Accompanying drawing explanation
Fig. 1 is prior art cantilever support axle construction schematic diagram.
Fig. 2 is the utility model cantilever support axle construction schematic diagram.
Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the utility model is described further.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 2, breathing cantilever support axle is batched in a kind of follow-on milling train uncoiling, comprise back shaft 1 and the contiguous block 2 with back shaft 1 matched together, improvements are, be provided with contiguous block 2 link position place the junction of the edges of two sheets of paper pin 4 that 4 run through axle head 10 axis at described back shaft 1 axle head 10, described junction of the edges of two sheets of paper pin 4 is along the circumferential uniform arrangement of axle head 10, and described junction of the edges of two sheets of paper pin 4 diameter is ￠ 25mm, and material is.
The utility model with on the basis of contiguous block 2 connected mode at original back shaft 1, is evenly squeezed into the junction of the edges of two sheets of paper pin 4 of 4 diameter 25mm at back shaft 1 and the junction circumferencial direction of contiguous block 2, is increased its anti-shear ability, effectively prevent junction fracture; Through the use of nearly 2 years; the back shaft 1 of this structure meets need of production completely; there is not the equipment fault that back shaft 1 and contiguous block 2 rupture again; greatly reduce the labour intensity of downtime and workman; also save material and maintenance cost simultaneously, only within 2 years, save spare part processing and fabricating expense and just reach about 16.5 ten thousand.
Claims (4)
