Single Chain Straight Line Cold Drawing Machine
Specification of Cold Drawing Machine
1, Chain drawing machine (pipe drawing) product overview:
Product application: This equipment is suitable for drawing
(drawing, cold drawing, polishing, drawing, twisting,
straightening, drawing, hexagon rectangle, etc.) of metal tube
(bar).
Mechanical layout: chain drawing machine
Equipment brand: Fangrong Taiwan brand drawing machine technology
2, Operation mode of chain drawing machine (pipe drawing machine):
After one end of the material is shrunk (indenter), it is held by
human hand and extended into the central frame of the drawing
machine. After being pneumatically clamped, the chain is hooked by
the chain and drawn. When drawing, the vibration of the machine
body is required to be small, the drawing speed is uniform and
stable, and the best precision of the finished product after
drawing is achieved, and the uniform surface of the finished
product is smooth and good quality. Generally, the above
requirements are reached after drawing.
