Take-up tension form: manual friction disc (tension adjustable);
Travel motor: BWED121-23×17-1.5KW (AC motor)
Lifting motor: BLD11-43-1.5KW (2 sets)
Clamping motor:Y90L-6-B5-1.1KW,960rpm
Structure form:
Longmen ground rail walking type, upper casing type structure. The
gantry is made of bending and welding. The two tops of the reel are
driven by two motors via a cycloid reducer to lift the screw nut.
Each apex can be lifted separately or simultaneously, and is
equipped with mechanical and electrical protection devices. It can
be equipped with different specifications of the top sleeve to meet
the installation of different specifications of the reel; the reel
clamping is realized by the motor cycloid reducer, and the clamping
overload protection is provided. The tension of the pay-off is
realized by manual friction disc, which is manually adjustable and
stable. Reliable and easy to operate. The take-up frame adopts the
centering device to realize the centering line.

heating ring has good heating and heat preservation performance.,
- Head: Huff clamp, easy to operate.
- Gearbox: All gears use 40Cr quenching and tempering, tooth surface
high frequency quenching treatment surface hardness HRC50-55, shaft
is treated with 45# steel quenching and tempering, the box material
is cast iron, the gear is inclined tooth surface grinding gear,
gearbox and screw Splined connection, one-way roller thrust
bearing.
4.Φ70mmRight angle head (with 1 set of die wrenches)
- Structure form: adjustable partial head, right angle circular
structure
- Heating form: cast aluminum heating
- Scope of application: the maximum diameter of the mold sleeve is
φ60mm, and the maximum extrusion core diameter is φ55mm
- Head material: surface nitriding treatment, nitriding depth
0.5-0.8mm, surface hardness ≥ HV840
Features: When replacing the core and the mold sleeve, the core rod
is not required to be dismantled. After the eccentricity is
adjusted at low speed, the concentricity is constant when the speed
is increased to the normal production speed. The eccentricity
requirement is less than 15%. After the low speed adjustment and
the synchronous speed increase Diameter deviation within the
standard tolerance of cable products
