Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a feeding and positioning device for metal stamping equipment. Background Technology

[0002] Stamping is a common sheet metal forming process that uses a press and dies to apply external force to sheet metal, strip, tube and profile to cause plastic deformation or separation, thereby obtaining workpieces of the required shape and size. Stamping is one of the main methods of metal plastic processing and is widely used in the automotive, electrical appliance, instrumentation and other fields. It can efficiently and in batches produce parts with complex shapes and high precision requirements.

[0003] The application number "202121782948.9" discloses "a robotic arm for stamping and feeding," which "includes a base, a movable platform movably mounted on the top of the base, a rotating shaft movably mounted on the top of the movable platform, a fixed rod fixedly mounted on the top of the rotating shaft, a movable rod movably mounted on the top of the fixed rod, a fixed rod top groove provided on the top of the fixed rod, fixed rod side grooves provided on both sides of the fixed rod, and a movable rod bottom buckle fixedly mounted on the bottom of the movable rod, the movable rod bottom buckle engaging with the interior of the fixed rod top groove." This utility model, through the cooperation of ball bearings and rollers, reduces the wear caused by the movement of the movable rod on the fixed rod, preventing wear from reducing the service life of the movable rod and thus preventing accidents during use.
