Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 to 4, the utility model provides a reinforcing is drawn and is rectified roller cooling increase of service life's structure, including center pin 1 and roller shell 2, first circular chamber 3 and second circular chamber 4 have from left to right been seted up in proper order in the left side of center pin 1, and the both sides at center pin 1 top have all been seted up and have been run through holistic first circular recess 5, and ring channel 6 has all been seted up at the both ends of 2 inner chambers of roller shell, and two ring channels 6 communicate through the second circular recess 7 in the outside.
Wherein, the quantity of second circular recess 7 is eighteen, and the equal angular distribution of second circular recess 7 annular is in the outside of ring channel 6, and the quantity of second circular recess 7 is more to even distribution is in the inside of roller shell 2, when pulling and straightening the inside cooling liquid that lets in of roller and cool down, area of contact is bigger, and the cooling effect is better.
Wherein, the diameter value and the length value of first circular chamber 3 all are greater than the diameter value and the length value of second circular chamber 4, and first circular chamber 3, second circular chamber 4, first circular recess 5, ring channel 6 and second circular recess 7 are linked together, and the inside first circular chamber 3 and the second circular chamber 4 of seting up of center pin 1 also can provide better stability and support nature when guaranteeing that the inner area is bigger.
