Abstract

The invention discloses a thermoforming production line and production method of variable-strength parts. The production line includes a destacking device, a feeding device, a first heating furnace, a second heating furnace, a discharging device, a press and a feeding device arranged in sequence. device, the discharge side of the first heating furnace is provided with a blowing cooling device, the press is provided with a variable strength coating mold, and the variable strength coating mold includes a soft area with a thermal barrier coating on the surface And the hard area with built-in cooling water circuit. The invention can partially and briefly cool the billet just out of the furnace, and control the forming temperature of the billet within an ideal range. For the variable strength thermoformed part, the position of the soft zone can be any position of the part, and at the same time, the transition interval between the soft zone and the hard zone is narrow, and the elongation of the soft zone is high, and the production efficiency is fast.

Description

technical field [0001] The invention relates to the field of thermoforming, in particular to a thermoforming production line and production method of variable-strength parts. Background technique [0002] At present, the high-strength thermoforming process prepares the hard zone of variable-strength thermoformed parts, usually by heating the blank above the complete austenite transformation temperature, that is, above 860°C, and then cooling rapidly, that is, at an average cooling rate of more than 27°C / s Only by cooling the mold at a high speed can an ultra-high-strength quenched structure with a tensile strength of 1500MPa mainly composed of martensite, that is, a hard zone. [0003] There are generally two ways to realize the soft zone, one is to reduce the heating temperature of the soft zone. Control the heating temperature in the soft zone below the initial temperature of austenite transformation at 700°C. The original structure ferrite / pearlite in this zone in the pl...
