Video: Four Holes For The Trunk Lid
With nine building blocks for automation, Tünkers Maschinenbau GmbH has a wide range of modules ready to meet challenges time and again through individual adjustments. So the company based in Ratingen got z. B. the task by a well-known German OEM to introduce the four holes for the license plate in the boot lid.
It should be a simple and inexpensive solution. That is also why the in-house engineers decided against the originally planned concept of using several punch pliers for this.

The robots of the future should be hairy
Derived from the standard C-frame from the Tünkers range, a C-frame was modified to meet customer requirements. The punch, designed as a C-frame, was equipped with an additional column guide for the widely spaced hole points. The drive is provided by a multi-force cylinder, a compressed air cylinder, which achieves the high punching force of 25 kN by means of the toggle lever transmission integrated in the housing. On a stand with an integrated pneumatic valve terminal and an attached angle bracket, the module can make the 4 holes in the 0.8 mm steel sheet in one work step thanks to the individually adapted tool holder.
