反向铜挤压机模具智能修整方法

Intelligent repair method for the die of indirect copper extrusion press

针对目前反向铜挤压机实现修模自动化的难点是修模装置无法自适应不同的模具,提出了一种自适应智能修模系统。该系统由模具旋转定位装置和自适应修模器组成,模具经旋转定位后,自适应修模器的磨刷在电机带动下旋转并伸入模孔进行打磨,没有模孔位置的磨刷杆在模具端面被弹回,从而实现对不同模孔数模具的自适应修整。同时,为更好的自动化、智能化模具修整,基于机器人自学习修模工艺及机器人示教技术,构建自适应修模器的数字化平台,机器人通过读取主机录入数据或利用视觉识别技术获取模具数据,根据机身姿态、夹具更换/夹持状态、模具状态等,设定工艺及算法进行修模,实现对不同规格模具修整的自适应。该系统已成功应用于2台设备上判别挤压筒和模具的清理及润滑效果,实施效果良好。

To address the difficulty in achieving automatic mold repair for reverse copper extrusion machines,which is that the repair device cannot adapt to different molds,a self-adaptive intelligent mold repair system is proposed.The system consists of the die rotation positioning device and the adaptive die-repair device.The system consists of a mold rotation positioning device and an adaptive mold repairer.After the mold is rotated and positioned,the grinding brush of the adaptive mold repairer rotates and extends into the mold hole for polishing under the drive of the motor.When there is no the mold hole,the grinding brush rod is bounced back on the end face of the mold,thus achieving adaptive repair of molds with different numbers of mold holes.At the same time,in order to realize better automate and intelligent die-repair,the digital platform for the die-repair device is constructed,based on the self-learning die-repair process and teaching technology of robot.The robot obtains the die data by the computer host input or the visual recognition technology.Then according to the robot body posture,fixture replacement and clamping state,die state,etc.,the process and algorithm are set to achieve adaptive repair of different die specifications.The system has been successfully applied to two devices to distinguish the cleaning and lubrication effects of the extrusion cylinder and mold,and the effect is good.
