Description

Technical Field

[0001] The utility model relates to the technical field of sensor processing, in particular to a novel terminal bending device. Background Art

[0002] like Figure 5 The sensor workpiece needs to be aligned with the terminal and bent 90° during the production process.

However, since the terminal will rebound after bending (the characteristics of the metal material itself), the actual angle after bending is between 92° and 93°, and the probability of defective products is relatively high. Therefore, we propose a new terminal bending device. Utility Model Content
