1. Brief description of unit configuration and performance
This machine is a special equipment for the production of
cold-rolled ribbed steel bars with two, the production line can be
6.5 Phi Phi 14mm Q235 hot rolled coil, cold rolled steel (Figure 1)
made of two crescent ribbed bar (Figure 2).
The complete set of equipment is composed of wire laying frame,
whole wire cage, descaling machine, rolling mill, main mill,
straightening, heating, temperature measuring, shearing, slideway,
two side material receiving, pneumatic automatic pushing and
take-up machine. The unit is designed according to the continuous
working system, and the whole set of equipment is controlled by PLC
Here is a brief description of the structure and properties of each
(1) release stand (see general drawing above)
The utility model has the function of ensuring the high-speed
operation of the unit. The utility model is composed of a double
discharge gun pipe, one is a work rack, the other is a reserve
storage rack, and the other barrel can be preloaded when a line is
placed. When working on the shelf after the end of the coil, the
coil coil and the other end welding rack hanging round grinding,
can continue to boot, then on another line to be pre frame
material, this material can be improved by pre design to reduce the
work efficiency after stop charging.
(2) whole wire cage, electric top and bottom descaling machine;
The whole wire cage is welded by the threaded steel, and the funnel
shape can change the steel bar from the annular to the spiral
straight strip, so as to ensure that the steel bar enters the
descaling machine before the descaling machine is basically
straight and ensures the high-speed and reliable operation of the
Dustproof descaling machine consists of 5 blocks, the main function
is the hot rolled coil through the 5 round of descaling repeated
bending surface oxide skin peeling, improve the surface quality of
steel, to reduce the effect on roll wear. The base plate is welded,
such as saving space, and can be mounted on a base with the
(3) pay rolling mill (see general drawing above)
After the steel bar passes through the rolling mill, the
reinforcing bar is rolled flat and the diameter is reduced, and the
main rolling mill is prepared by thread rolling, and the rolling
mill is an active rolling mill, and the active rolling mill has
1, there is no scrap when threading.
2, the initiative to pay the mill, steel welding is not good, poor
material, nor will it break.
3, because the roller is active, phosphorus removal and reduction
of diameter are driven by rolling mills, the main mill thread
roller does not bear tension, and the service life of the screw
roll is doubled and redoubled.
4, can roll a large amount of compression steel, such as Phi 12mm
rolled to Phi 9.5mm, roll will not break
(4) main mill (see general drawing above)
The main rolling mill is the last process of forming the thread
steel. The rolling mill has large force, and requires the high
precision of the rolling mill and the following advantages of the
1, center adjustment, (domestic unique) size of old and new roll,
rolling center do not tune.
2, roll replacement is convenient, (domestic unique) slideway,
drawer type replacement, 10 minutes to fix.
3, a high degree of automation, (domestic unique) fully automatic
concentric, for steel import and export without adjustment, the
world's leading technology.
4, the integration of high-precision guidance, (domestic unique) up
and down around, a guide can be achieved.
5. The roll has a long practical life and can be rolled up to over
10000 tons at one time.
Computer numerical control automatic butter 6, unique to the
system, solve the workers do not timely oil bearing damage.
The only console to mill, heating, blanking, cutting, feeding, and
push down steel swing, concentrated in a panel, truly integrated
centralized control, to control the head on the mill, do not take a
place, can install more equipment in the limited plant, using PLC
program control system, touch screen display, can improve the
stability of equipment operation and intuitive display fault
location through the touch screen.
