LFT-D模压生产线上下料的关键技术

Key technology of feeding and unloading in LFT-D molding line

为了解决熔融状态LFT-D难以拾取及上料效率低下的问题,通过采用上下料一体端拾器可提升效率15%~20%。同时,采用短距离自动化拾取,减少了热熔LFT-D的温度散失,从而降低能耗。将坯料从拾取位置转运至上料位置温度下降可控制在15%以内,提升了产品成形质量,废品率减少4%~10%。通过调整刺针倾角和行程,解决了材料高温及流动性难以拾取的问题。同时,横臂气动线性模组可在机器人运行时自动调节双工位间距,可适应取料与上下料工位间距不同的情况。端拾器主杆及横纵臂采用轻质铝合金材料,有效减小机器人负载。

In order to solve the problems of pick-up difficultly and low efficiency of feeding for LFT-D in molten condition,the efficiency could be improved by 15%-20% by the feeding and unloading integral tooling. At the same time,the temperature dissipation of hot molten LFT-D was reduced by taking short distance automatic picking up,and the energy consumption was decreased. Therefore,the temperature drop of billet from the picking position to the feeding position can be controlled within 15%,and the forming quality of product was improved with the reject rate reduces from 4% to 10%. Thus,the high temperature and the flowability of the material pick-up difficulty are solved by adjusting the angle and stroke of needle. At the same time,the cross-arm pneumatic linear module can adjust the double-station spacing automatically when the robot is running,which can be adapted to the different distances between the picking station and the loading station. Furthermore,the main rod and the longitudinal arm of pole are made of lightweight aluminum alloy material,and the load of robot is reduced effectively.
