V. Structure Performance of the Machine
The machine mainly consists of traction straightening part, hydraulic cutting part, blanking frame, and electric control cabinet.
4.1 Straightening Part
The part consists of two Models: straightening cylinder Model (GT4-12D) and straightening frame Model (GT4-12B).
4.11 Straightening cylinder Model (GT4-12D) mainly adjusts the straightness of linear material through adjusting shift of mould in cylinder. The rotation of straightening cylinder straightens linear material.
4.12 Straightening frame Model (GT4-12B) mainly uses several sets of straightening wheels and straightening frame rotates linear materials, which completely eliminate stress and operate linear material. Use the adjustment wire of straightening wheel to adjust the straightness of linear materials, so as to straighten linear materials.
4.2 Traction Part
The part mainly consists of drive assembly, traction assembly, and reduction gear. Use electromotor as power. Through triangular belt, drive reduction gear, which drives traction assembly, traction wheel, and chain wheel. The chain wheel drives drive traction to transport materials.
4.3 Cutting Part
The part is controlled by hydraulic pump driven by motor through magnetic exchange valve and safe pressure control valve. The piston rod of oil cylinder of trolley which balances guide rail is installed with active cutting tool, which intersects with fixed circular cutting tool installed on oil cylinder base, so as to cut the linear materials. As linear materials are cut during operation, the instantaneous resistance during cutting drives movable trolley to move, forming following-cutting tool movement. After piston rod drives the cutting tool to return, the linear material eliminates resistance. At the moment, movable trolley returns to original position under the influence of spring, and is in state of cutting. The cutting part mainly consists of motor, gear pump, magnetic exchange valve, integrated module, movable trolley, oil cylinder, balance guide rail, high-pressure oil pipe, and fuel tank. During operation, limiting stopper sends out signal to the time relay in electric control cabinet to control magnetic exchange valve. After exchange, the output hydraulic oil, under the influence of safety pressure control valve, drives oil cylinder piston and cutting tool. While passing tool bore of round cutting tool, cut the linear material operating in round cutting tool. At the moment, time relay in electric cabinet cuts off power supply of magnetic exchange valve under the influence of delaying to cut off power supply (control is about 0.12 seconds), The reset spring in oil cylinder quickly drives the reset of oil cylinder position and cutting tool, so as to complete the cyclic process of cutting off single Steel Bar. When linear material drives limiting stopper, it also sends counter signal, then counter records one time. After cutting off certain amount of linear materials, the counter automatically losses power, cutting off the circuit of system and forming automatic stop. If restart the machine, press the button of zero clearing or reset to make the counter reset, or the host machine cannot restart. 
4.4 Blanking Frame Part (Manual Model)
When straightening linear material passes the round cutting tool on movable trolley, after it enters blanking frame, it moves to specified dimension. Through travel switch, cut the Steel Bar.
4.5 Control of Electric Device
Consists of ordinary-Model (manual scale of travel switch) and digital control Model (encoder automatically counts)
V. Machine Installation and Debugging
5.1 Before installation of the whole machine make sure to finish the following procedures:
5.11 Check whether components are complete and positions are correct.
5.12 If the machine is close to wall or other structures, reserve enough space for equipment maintenance and site maintenance during installation of machine (generally about 1m).
5.13 Reserve broad site for raw material stock and transporting finished products.
5.14 Flat concrete foundation (11000mm length×1500mm width×200mm thickness) shall be provided.
5.2 Installation of Host Machine
Use M12 expansion bolt to install several foot margins of host machine on concrete base (note: level down the host machine)
Then fix blanking frame. Pay attention that the feed opening, centers of two slots in straightening traction wheel, trolley fixed round cutting tool center, and blanking frame shall be in the same straight line. The blanking frame shall be about 20mm lower than host machine.
5.3 Connect with Power Supply
Put electric cabinet on the place which is about 1.5m away from host machine and free from vibration. Respectively insert each cable plug in socket of electric cabinet. After checking, connect power line with "power supply" binding post (note: the power line shall not be less than 6mm2 copper cable of China's standard within 30m!)
VI. The Working Principle and Adjustment Method of Hydraulic Station
The power of hydraulic station is provided by electric engine, which drives CB-FC32# gear pump to supply oil. The output hydraulic oil enters shunt integrated block and magnetic exchange valve. When it does work, oil circuit does not form pressure. Oil directly enters fuel tank from magnetic exchange valve installed on integrated block. During operation, under the command of electric cabinet, the electric cabinet controls oil circuit (due to the function of safety pressure control valve, oil circuit forms certain pressure.). While entering high-pressure oil pipe, the piston rod in oil cylinder pushes out (namely cutting off). Under the influence that time relay in control cabinet cuts off power supply (control is about 0.12 second) of magnetic exchange valve, the reset spring in oil cylinder quickly pushes piston rod of oil cylinder to reset (namely reset of cutting tool). Time relay in electric cabinet is used to adjust cutting time, generally 0.12 second (digital display is 12). In case the linear material is not cut off, add one number for cutting time.

The factory setting has already been set. If not necessary, layman shall not change it, so as to protect parts.
VII. No-load Commissioning

At the same time, check each parameter according to the notice on operation panel of electric equipment control cabinet. After it is normal, press "operation" button. At the moment, the motor starts. Check the rotation direction of motor. Change wire end if motor rotates reversely. After it is correct, press "cut off" button, then the cutting procedure is normal. 
3. After checking, please set aside shield and press "go forward " (or "operation") button, then the machine operates for several minutes. The drive system shall be stable, without vibration or abnormal noises. The movable trolley shall be stable and flexible. If the machine is ordinary Model, install travel switch on the position of blanking frame. Check whether fastener is fixed. After all goes normal, conduct test run with load.
4. Pull linear material about 2m. Release traction wheel. Put spring bearer plate on sliding block. Install the prepared linear materials according to the procedure of feeding-hole water-proof casing-impelling assembly traction wheel-straightening frame-traction assembly traction wheel-round cutting tool hole. Then adjust proper curve to straighten Steel Bar.
Attention: after adjusting curve, tighten lock nut. Input the quantity of bar and set the length, then start the machine.
