specific Embodiment approach 1
[0024] A processing method for a wedge-shaped plate forging, the technological process of the processing method for a wedge-shaped plate forging is as follows: heating the steel ingot → pressing the jaw → chamfering → removing the bottom of the ingot → upsetting for the first time → drawing a rectangular blank for the first time → The second upsetting → The second drawing of the rectangular blank → The third drawing of the rectangular blank → Half-die forging with a special upper anvil → Heat treatment → Finishing each part to the finished product size, the special upper anvil is an upper flat slope Anvil, the angle between the bottom edge of the upper flat slope anvil and the horizontal plane is the same as the wedge angle of the wedge plate forging.
[0025] The processing method of a wedge-shaped plate forging described in this embodiment, in the processing method of a wedge-shaped plate forging, a 30MN hydraulic press is used for forging, and the steel ingot weighs 9.3 tons...
