Precision and efficient ring piece hot rolling whole-process automatic production line and application method thereof

Abstract

The invention discloses a precision and efficient ring piece hot rolling whole-process automatic production line and an application method thereof. The precision and efficient ring piece hot rolling whole-process automatic production line comprises a discharging production line and a full-automatic efficient ring piece production line. The discharging production line comprises a logistics channel,a raw material site, a full-automatic discharging area, an automatic material cutting part and a blank area. The blank full-automatic efficient ring piece production line comprises a sliding way barsteel pushing heating furnace, a stoker burdening chamber, a press machine operation chamber, a 1200 T punching blank making press machine, a fixing feeder, an online ring piece finishing machine, a material taking machine, a ring piece cooling bed, a material table, a heat treatment furnace, a quenching trolley and a quenching pond. The precision and efficient ring piece hot rolling whole-processautomatic production line and the application method thereof have the beneficial effects that the layout is reasonable, ring piece blanks are discharged, the heating furnace is used for conducting heating, the press machine is used for blank making, a ring rolling machine conducts ring rolling, finishing and automatic stacking are conducted, and connecting and matching between heat treatment tight equipment devices are finished; and a special fixing mechanical arm is used for decomposing production resistance, controllable, convenient and automatic connection-in is achieved, and efficient hotrolling ring piece whole-process automatic production is achieved.

Description

Technical field [0001] The invention relates to a ring rolling production line, and more specifically, to a ring precision and high-efficiency hot rolling full-process automatic production line and a use method thereof. Background technique [0002] Ring rolling is also called ring rolling or reaming. It uses the ring rolling equipment-ring rolling machine (also called rolling and expanding machine or reaming machine) to reduce the wall thickness, expand the diameter of the ring. Plastic processing technology for section profile forming. It is widely used in the fields of machinery, automobiles, trains, ships, aviation, aerospace, petrochemical industry, and nuclear energy industry. In the past ten years, the equipment for ring rolling production has been rapidly developed. Rings with a diameter of 12 meters have been successfully rolled, and the wall thickness and height of the ring have been continuously updated. The maximum pressure of the hydraulic press for ring forging bi...

Problems solved by technology

[0005] Multiple metal band saws blanking, continuous sawing for 24 hours for continuous casting slab blanking, one metal band saw blanking takes an average of 25 minutes per piece, the workpiece weight error is large, which will affect the post-processing; multiple metal band saws Blanking, continuous sawing for 24 hours for continuous casting slab blanking, a metal band saw blanking takes an average of 25 minutes per piece, and the weight error of the workpiece is large

[0006] Chamber-type gas-fired forging furnace billet heating chamber-type furnace, the billets are stacked in the furnace, and the human brain memory records, billet random numbers cannot be avoided

It is necessary to open the furnace door every time the material is taken out, the heat loss is very large, the rapid cooling and heating will reduce the furnace body, and the life of the furnace door is short

[0007] It takes more than 2 minutes for the two-station punching of the forging hydraulic machine blank in the prior art, and the multi-station is prone to produce inner hole defects such as skinning and reverse sides. The manufacturer needs to increase the blank feeding in advance and take into account the process material loss. If the size of the defect is out of tolerance, it will become a waste product, and the process is called inner diameter folding

[0008] Manual hoisting is used for the stacking of ring parts, and there are hidden dangers to the safety of employees during the hoisting process;
