钛合金紧固件作为航天、航空等军工领域的重要联接件,但在镦锻时对温度一直有严格的要求,不能低于650℃出现开裂的温度,也不能高于800℃的再结晶温度,因此,现有传统的冷镦设备无法完成钛合金紧固件的镦锻加工。1.方案提出Z12-8A冷镦机(见图1)是传统螺栓的批量生产设备,现作为典型设备对其改造,选择加热方式是此次冷镦机改造成功的关键所在。本次Z12-8A冷镦机采用高频感应加热设备加热,主要是因
Titanium alloy fasteners as aerospace, aviation and other military areas an important link, but upsetting the temperature has been strict requirements, not less than 650 ℃ cracking temperature, nor higher than 800 ℃ recrystallization temperature , Therefore, the existing conventional cold heading equipment can not complete upsetting of titanium alloy fasteners. 1. Program Proposed Z12-8A cold heading machine (see Figure 1) is a traditional mass production equipment bolts, as a typical equipment to transform it, select the heating method is the key to the successful transformation of the cold heading machine. The Z12-8A cold heading machine using high-frequency induction heating equipment, mainly due to
