High Efficiency Automatic Rolling Machine Simple Design 55-75KW Motor

Introduction:
Cold rolling machine, also known as rolling mill, reinforcing bar reducing mill, rebar scoring machine, round steel gin, etc., has a simple design. As long as the pressure difference is appropriate, the cold-rolled material roll matching special spindle can be used to complete the reduction , scoring, etc., for more details, you can call or ask for relevant information. The cold-rolled ribbed steel bar is a steel bar with two-sided or three-sided crescent shape formed by hot rolled coil through multiple cold rolling reduction, one pressing rib and eliminating internal stress. Cold-rolled ribbed steel is a new generation of cold-drawn low-carbon steel wire in prestressed concrete members. In the cast-in-situ concrete structure, it can replace the grade I steel to save steel, which is better than those in the same kind of cold-work steel.


There are innovative improvements in performance of the products produced by our production line. The elongation A11.3 reaches 12%, which is 50% higher than A11.3≥8% of national standards. Meanwhile, the Agt is doubled by standard, the tensile strength is increased by 100Mpa, and the bond strength is 4 to 5 times higher than that of the hot-rolled steel bar. Compared with the I-class steel, our products can save 40%~50% of the steel and save 50~70Kg of the cement.


Continuous rolling doubles the production efficiency, automatic, continuous and high-speed operation of the entire production line realized. Equipment operating rate, production operation rate, roll replacement efficiency, and input-output ratio have all reached international advanced levels.

Reasonable structure, process and layout
The rolling machine adopts the main and passive one-rolling and one-towing type to realize two rolling forming, which solves the problem that the speed of the four rolls of rolling machine is difficult to match, makes the equipment run stably. And the machine adopts the numerical control intermediate frequency heating, the numerical control fly shearing, fully automatic turning machine technology, all of which making it a complete cold rolling new process and significantly improving the product quality.


Before rolling, the shelling technology is adopted to remove the oxide scale, so that the bonding strength between the steel and the concrete gets greatly improved.
The rolling machine adopts the self-locking method of the roll to solve the vibration caused by the gap between the roll and the machine base, which would cause the problem that the roll is abnormally broken, difficultly disassembled and installed . Meanwhile , the effective length of the roll body is increased and make it multi-purpose. So there is no need to replace the roll to produce 6 ~ 8 specifications (Ф 5.5mm ~ Ф 12mm) of products.


This rolling machine adopts linear guide rail, guide seat and booster guide wheel device to change the traditional passive guide position with good stability.
It adopts PLC programming control, soft start technology, frequency conversion technology, servo control technology, photoelectric induction technology, numerical control technology and other international advanced practical technologies to meet advanced world standards.


This equipment consist of seven major components:
1) Phosphor removal machine 2) Reduction machine (ie rolling machine) 3) Main rolling machine (ie rolling thread) 4) On-line heat treatment device (ie normalizing heating equipment) 5) Fixed length shear 6) Cooling bed (ie blanking rack) 7) Guide device
The function of phosphor removal machine: a device for shelling hot rolled 195 high speed wire or Q235 base metal.
The function of the reduction machine: on-line flattening of base metal after phosphorus removal (referred to as the vertical rolling mill).
The function of main rolling machine: rolling pattern on base metal after reduction’s completion (referred to as flat rolling).
The function of the guide device: on-line positioning correction of rolled steel bar (so that the rolled steel bars do not fall steel)
The function of on-line heat treatment device : on-line normalizing of patterned steel bar that rolling finished (stabilizing lattice inside the steel bar).
The function of fixed length shear: 9m|12m shearing of on-line rolled rebar (making a certain number of meters cut according to the requirements of the steel distributor or construction site ).
The function of cooling bed: a device for naturally cooling the temperature of rebar after on-line rolling and heating completed.

Technical parameters of cold rolled ribbed steel bar

Application:
Two-sided rebar, three-sided rebar, flat steel, square steel, steel plate, scrap rebar, ship sheet, leftover bits and pieces, billet, etc.
More heterogeneous or special materials can be customized.



Detailed accessories description of complete Cold rolling machine:

Cold rolling machine parts: 1) start baler 2) butt welder 3) guide wheel
Heating part: 1) sensor set for each device 2) mica tube 3) online thermometer 4) soft water processor

The production line covers an area of 35-40m in length and 3.5-5m in width. The maximum speed of rolling line is 2.5mS.


Shipping standard:

The fumigation-free template is used to reinforce the compression plate. Custom according to the length, width and height of the machine, the peripheral metal material is reinforced to ensure the reliability during transportation. When loading on the container, each device needs to be reinforced in advance to ensure the stability during transportation.
