[CN 201610453924.6] Processing Technology of Upper and Lower V-shaped Anvils of Electrohydraulic Hammer
[CN 201610453924.6] Title of processing technology for upper and lower V-anvils of electro-hydraulic hammer: Application number of processing technology for upper and lower V-anvils of electro-hydraulic hammer: CN 201610453924.6 Applicant: Anhui Ruijie Forging Co., Ltd. Application Date: 2016-6-20 Patent Type: Invention Application for processing technology for upper and lower V-anvils of electro-hydraulic hammer, which belongs to the technical field of upper and lower V-anvil processing of electro-hydraulic hammer. The process consists of the following steps:(1) blank selection, the billet is placed on the sawing machine for rough machining, and the opening angles of the upper and lower V-shaped anvils are 105~115 °;(2) The billet is placed in a heating furnace for a heating, and then a heat preservation;(3) The billet is heated twice, and then the second heat preservation is carried out, and then the billet is quenched in oil, and the billet temperature is cooled to 400~500 ℃;(4) The blank after quenching is heated three times, then insulated three times, then discharged from the furnace and air cooled to 260~320 ℃;(5) The blank is heated four times, then insulated four times, and then cooled to room temperature in the furnace. The V-shaped anvil of the present invention will not break laterally; the V-shaped anvil of the present invention will not wear out and has a long service life; the product processed by the V-shaped anvil of the present invention is of good quality.
