Description

TECHNICAL FIELD

[0001] The present application relates to the field of horizontal ring rolling machine assembly technology, and particularly relates to a horizontal ring rolling machine core roller and die assembly system and assembly method. BACKGROUND

[0002] Annular forgings are widely used in various industries, and existing annular forgings have different shapes, including large annular forgings with a diameter of more than 2 m. Currently, large annular forgings with a diameter of more than 2 m are mainly produced by horizontal ring rolling machines. Due to fierce market competition, product imitation rolling is currently considered in production, which requires the design of corresponding ring rolling dies for forming processing of forgings.

[0003] The shape of the ring rolling die can be designed and processed according to the shape of the product to be produced and the process properties. The current problem to be solved is the assembly of the ring rolling die and the ring rolling machine. In particular, when there are various dies and frequent changes, a method for easily disassembling the ring rolling die on the ring rolling machine is urgently needed.

[0004] Due to the large diameter of the main roller of the horizontal ring rolling machine and the high cost of the die, the core roller die is mainly used. The existing horizontal ring rolling machine is mostly an upper extraction core roller, which is convenient for hoisting the forgings up and down, and is more favorable for rolling cylindrical parts with a small horn.

[0005] Currently, the following problems exist when assembling the core roller and die of the horizontal ring rolling machine:

[0006] 1. The core roller needs to be disassembled first, then the die is assembled, and then the core roller is assembled on the horizontal ring rolling machine, which causes a long disassembly and assembly time of the core roller and low production efficiency.

[0007] 2. At least two core rollers are needed, one of which is used on the horizontal ring rolling machine, and the other is assembled with the die and is ready to be replaced at any time according to production arrangements, which increases the cost of investment.

[0008] 3. Bolts are needed for the assembly of the die and the core roller, and the bolts are prone to deformation and fracture under large rolling force, making it difficult to disassemble.

[0009] Therefore, there is a need to develop a new type of horizontal ring rolling machine core roller and die assembly system and assembly method to overcome and improve one or more of the above-mentioned problems in the prior art, or at least to provide an effective alternative method to solve the above-mentioned problems.

If the first size value is equal to the second size value, the baffle 40 is not required in the horizontal ring rolling core roller 10 and die 20 assembly system, and reliable connection of the core roller 10 and the die 20 can be achieved. If the first size value is less than the second size value, the baffle 40 is required between the core roller 10 and the die 20.
