Automatic Metal Steel Tube Pipe Bar Elevator Guide Rail Cold
Drawing Machine
Usage for Cold Drawing Machine
It is used to reduce the diameter of round steel and make the
diameter of round steel reach the size of rolling wire. This
machine can pull out the old screw steel into round steel once,
which can be renovated and reused.
Specification of Cold Drawing Machine
1. Equipment Overview
A. This equipment is applicable to the drawing (drawing, cold
drawing, light drawing and flower drawing) processing equipment of
metal tube (bar)
B. Mechanical structure double chain drawing machine Taiwan brand
drawing machine technology
2. After one end of the working mode material is reduced by the
indenter (indenter), it is held by human hand and extended into the
central frame mold of the drawing machine. After being
pneumatically clamped, the chain hooks the chain for drawing. 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, so as to achieve
the uniform surface, smooth and good quality of the finished
product. Generally, the above requirements are achieved after
drawing
3. Equipment capacity
A. Stretch form 1 line stretch
B. Tensile force 150kn
C. Tensile speed 0-12m / min
D. Tensile length 9m
E. Core pulling length (propeller length) effective length 8M
F. The maximum outer diameter of plain pipe is ф 100mm, and the
wall thickness is 2.5mm
G. Center height 800mm
4. Machine construction
A. Motor and operation panel
(1) Type-45kw1 excitation speed regulating motor, reducer zq-850
1:48.75 1 trolley speed reducing motor 2.2kW 15:1 1 1
(2) Output
(3) Speed
(4) Power supply voltage 380V 50-60Hz
5. Drive part
(1) Frame C360 C160 channel steel and flat steel 30 * 40 welding
main frame: C360 * 12000 core pulling frame C360 * 10000
(2) Chain 48b-2 Taiwan chain
(3) Sprocket shaft Ф 125
6. Structure of supporting part
(1) Mould base spherical mould ф 260mm
(2) Die mounting frame steel plate welding structure (cylinder push
in rod internal mold)
(3) Feeder cylinder rocker arm rotating material receiving
(4) The feeder is equipped with manual feeding. If it is necessary
to automatically feed the rack (roll into the sliding groove, the
reduction motor pushes into the core drawing die, the core drawing
die automatically rises and penetrates into the material, then it
is lowered to the horizontal position, and pushed into the drawing
die by the tailstock cylinder), RMB 30000.00 will be added
(6) Drawing trolley pneumatic clamp, clamp arm, pneumatic chain
hook, return chain drive belt deceleration
(7) Automatic cutting none
(8) High pressure and high temperature oil pump, internal and
external mold pump oil at the same time
