A kind of thin metallic tubd punching punch press that can be accurately positioned quick feeding
The present invention relates to punch press technical field, in particular, particularly relate to a kind of thin-walled gold that can be accurately positioned quick feeding
Belong to pipe punching punch press.
In field of machining, the processing that carries out particular requirement single-ended to thin metallic tubd is the most common.Thin metallic tubd needs
Charging equipment to be passed through or be transported to Working position manually, being then processed by processing unit (plant) through clamping device is fixing again.
Existing thin metallic tubd feeder structure is relatively simple, is usually and uses conveyer belt directly to carry, then is entered by clamping device
Row clamping feeding, not only clamping and positioning precision is low, and operates comparatively laborious, and automaticity is low, it is often necessary to manually carry out
Simultaneously during thin metallic tubd is processed, generally require and thin metallic tubd is rotated a whole circle, generally use cylinder dress
Folder thin metallic tubd, motor-driven cylinder rotates a circle and realizes；If this process only often determines the zero-bit of processing with motor
There will be deviation, need the operation using block to carry out zero setting the most before processing；Use the block being fixed on cylinder with solid
The block being scheduled on base mutually blocks and realizes owing to block itself occupies certain volume during zero-bit determines, therefore,
Cannot really realize the rotation of 360 degree, and can 1-2 degree less than normal；It is specific that the deviation of this 1-2 degree often makes workpiece to turn to
Angle thus the manufacturing procedure of whole circle cannot be completed.
