3, Machine Features
This equipment is specially designed for customers to produce
fixed-size sheet metal angle products.
The production process is as follows: the coil to be processed is
manually placed on the discharge rack, then corrected and
tensioned, manually introduced into the leveling machine for sheet
leveling, and then into the angle mold. The feeding is completed by
the servo feeder, and the fixed length feeding of the multi-station
can be completed by the electric control. After the set length is
reached, the sheet is cut and manually collected at the rear.
The main frame of this equipment is welded by the whole profile,
which has good rigidity and stable structure. In the production
process, it is a bit moving, automatic, reversing and other
functions. The electrical system is equipped with an overload
protection device to prevent damage caused by inadvertent overload.
The equipment is mainly composed of a cantilever hydraulic
discharge rack, a leveling servo feeder, an angle punching mold, a
cutting die, a hydraulic system, an electric control system, a
transmission part, and a safety protection part.
1. Hydraulic uncoiler: used to store the coil and provide sheets to
the forming section. The single cantilever structure is adopted,
and the frame is welded by steel plate and steel. The shaft core is
composed of a set of circular sliders. The welded integrated
structure can be freely tensioned within the range of φ460～φ520mm.
The cantilever support is adopted. Hydraulic expansion and
contraction claw structure. After the roller is positioned, the
uncoiler will push the ups and downs into the inner hole of the
coil, and the open jaw will tighten the coil, and the unwinder will
lower the coil and manually unwind the coil. Start the motor to
rotate the uncoiler and introduce the end of the plate into the
leveler. The brakes use advanced pneumatic disc brakes. The
uncoiler has a load of 5 tons.
2. Leveling the servo feeder: Correcting the plate material so that
the straight sheet can smoothly enter the next step. There are 2
pinch rolls, the upper roll bread PU glue, and the lower roll
surface is heat-treated and plated with hard chrome. There are 7
leveling rolls (4 upper and 3 lower), two counting rolls, the
diameter is about 105mm, the material is 40Cr, after quenching and
tempering, surface high-frequency heat treatment, surface grinding
and chrome plating and grinding again. The leveling roller is
controlled by Yaskawa servo motor and counted by the encoder to
form a closed-loop feedback system with high dimensional accuracy.
3. Angle punching dies, cutting die: complete the punching angle
and fixed length cutting of the workpiece. The opening width of the
punching die is adjusted by the manual screw.
4. Hydraulic part: The whole part of the hydraulic components has
good performance. The components such as solenoid valve adopt
Beijing Huade products to ensure the accuracy and timeliness of the
action execution. The punching die has excellent material quality,
long service life and convenient replacement. The product after the
crushing is smooth and flat.
5. Electrical control system: The system adopts the programmable
controller produced by Mitsubishi of Japan as the core control
device and implements full automatic control. The drive unit uses
AC servo system from Yaskawa, Japan to implement high-precision
position control. The man-machine interface is Weilun
high-resolution touch screen, the system interface is easy to
operate, and there are multiple product production specifications
according to customer requirements. It is directly called in the
production process. Each specification has an independent output
calculation function, which is convenient for operators to press.
Single production. The electrical design complies with national
safety standards, such as emergency stop device, leakage overload
protection, interlocking safety device, etc., to ensure safe and
smooth operation throughout the entire process.
