Detailed Description
The wide billet withdrawal and straightening machine shown in fig. 1 to 3 in the attached drawings of the specification comprises a rack 1 and a crop shear 2 arranged at an outlet of the rack 1, wherein a group of two withdrawal and straightening rollers 3 aligned up and down are respectively installed on two sides of the rack 1, a hydraulic cylinder 4 is fixedly arranged between the two groups of withdrawal and straightening rollers 3, a group of tension rollers 5 are connected onto the hydraulic cylinder 4, a cooling channel 6 is arranged in each withdrawal and straightening roller 3, one end of each cooling channel 6 is provided with a cooling liquid inlet 7, and the other end of each cooling channel 6 is provided with a cooling liquid outlet 8.
The cooling liquid inlet 7 and the cooling liquid outlet 8 both comprise a fixed pipe 9 and a connecting pipe 10, the outlet end of the fixed pipe 9 is sleeved on the outer ring of the bearing 11, and the inner ring of the bearing 11 is inserted into the inlet end of the connecting pipe 10.
A set of two tension rollers 5 is staggered.
When the cooling device is used, cooling liquid enters the cooling channel 6 from the connecting pipe 10 and the fixed pipe 9 of the cooling liquid inlet 7 to cool the pulling and straightening roller 3, then the cooling liquid goes out from the connecting pipe 10 and the fixed pipe 9 of the cooling liquid outlet 8, the fixed pipe 9 and the connecting pipe 10 are connected through the bearing 11 in a manner similar to a rotary joint, and the cooling liquid can enter the cooling channel 6 when the pulling and straightening roller 3 rotates;
and simultaneously, the hydraulic cylinder 4 is started, and a group of two tension rollers 5 which are arranged in a vertically staggered manner and connected to the hydraulic cylinder 4 can move up and down to keep the billet straightening and pulling stability (the group of two tension rollers 5 which are arranged in a vertically staggered manner and connected to the hydraulic cylinder 4 is well known by those skilled in the art, and the specific connection mode does not need to be described in detail herein).
In summary, the present invention is only a preferred embodiment, and is not intended to limit the scope of the present invention, and all equivalent changes and modifications of the shapes, structures, features and spirit described in the claims of the present invention should be included in the scope of the present invention.
