 Brief introduction 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 16mm Q235 hot rolled coil, cold rolled steel (Figure 1) made of two crescent ribbed bar (Figure 2) 

 Figure 1 Figure 2 with two round steel 

 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 system. 

 Here is a brief description of the structure and properties of each component: 

 (1) stringing frame; 

 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 machine. 

 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 mainframe. 

 (3) pay mill 

 The reinforcing bar is rolled flat and reduced by the rolling mill, the main rolling thread is prepared, and the rolling mill is a double active mill. 

 (4) main mill 

 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 rolling mill: 

 1, center adjustment, (domestic unique) size of old and new roll, rolling center do not tune 

 2. The roller has a long service life and can be rolled up to over 10000 tons at one time. 

 3, roll replacement is convenient, (domestic unique) slideway, drawer type replacement, 10 minutes to fix. 

 4, a high degree of automation, (domestic unique) fully automatic concentric, for steel import and export without adjustment, the world's leading technology. 

 5. The spindle has automatic cooling system (unique in China) 

 6, the integration of high-precision guidance, (domestic unique) up and down around, a guide can be achieved. 

 Computer numerical control automatic butter 7, unique to the system, solve the workers do not timely oil bearing damage. 

 (5) console 

 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 account for the workshop position, 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.
