System is not easy, low production efficiency, is not suitable for producing in batches, and especially in roughing, profile surplus is big, when Vehicle Processing consumption is substantial amounts of
Between and energy, reduce the quality of product.
Utility model content
The technical problems to be solved in the utility model is：It is small to provide a kind of material consumption, is adapted to batch production, is easy to draw
The rolling mill of system punch roller special-shaped forge parts.
Technical scheme is used by the utility model solves its technical problem：
A kind of rolling mill punch roller special-shaped forge parts, including machine roller body, the center of machine roller body are provided with through hole,
Through hole includes the first endoporus, the second endoporus and the 3rd endoporus that diameter gradually increases, the both ends of the first endoporus successively from left to right
Provided with 30 ° of chamferings, the left end of the 3rd endoporus is provided with 45 ° of chamferings, and the length of the first endoporus, the 3rd endoporus and the second endoporus subtracts successively
Small, the outer surface of machine roller body includes First Transition portion, the first bevel phase and the second bevel phase and the second mistake successively from left to right
Portion is crossed, into the first angle between the first bevel phase and horizontal plane, the second bevel phase is with the horizontal the second angle, First Transition portion
Shape with the second transition part is cylinder, and the diameter in First Transition portion is less than the diameter of the second transition part, the first bevel phase
Shape with the second bevel phase is the diameter phase of truncated cone-shaped, the diameter of the first bevel phase bottom surface and the second bevel phase upper bottom surface
Together.
Further, the angle of the first angle is more than the angle of the second angle.
Further, the angle of the first angle is 17.5 °, and the angle of the second angle is 9 °.
Further, machine roller body is formed in one structure.
The beneficial effects of the utility model are：This programme material consumption is small, can obtain strong dimensional tolerance, saves former material
Material, reduces cost of parts, easy to operate so as to save the consumption such as natural gas, electricity life, is easy to draw, production efficiency is high, fits
Batch production is closed, has in raising and stabilized product quality.
