Project Description
How to use a rebar stirrups bender GF20 and GF25 (manuals of GF20 and GF25 rebar stirrups bender)
- Before using the rebar stirrups bender, please read this operating manual carefully
Tech details specification of the rebar stirrups bender
- Operators should have an overview knowing tech details before using the machine
Machine Model GF20 GF25 Bending Capacity Ø4mm-Ø20mm Ø4mm-Ø25mm Bending Frequency 25-30 times per minute 25-30 times per minute Motor Power 2.2Kw 3Kw Motor Speed 1450RPM 1450RPM GW/NW 140Kg/120Kg 180Kg/150Kg Package Dimension 820*590*800mm 820*650*820mm
Commissioning
- Connect power line to power source(380V,three phase), if the machine is customized with other voltages, go with the customized electricity
- It’s better to use a Reverse Switch, because it can change phase by the switch easily,
- Turn on power switch and push any one footswitch, to see if work bench rolling in right direction as arrow indicates, if not right direction, change the Revers Switch to other sider, it will be OK. DO THIS TEST WITHOUT LOAD
- Lay a rebar on working bench, and adjust clamp plates tough rebar as near as possible, then push the footswitch, anyone (90 degree and 135 degree) is OK.
- If it works no problem, then you can go ahead with heavy duty work
Angle degrees changing
- Factory settings: 90 degree and 135 degree in Angle degree integrated control center
- If you want to bend a degree that is below 90, adjust the 90 degree angle degree clamp controller to the point as you required,
- If you want to bend a degree that is above 135, adjust the 135 degree angle degree clamp controller to the point as you required,
- The two footswitch (90 and 135) are matched with the Angle Degree Integrated Control Center
Fault handling (Machine can’t bend)
- Please check if the rebar size is over load, GF20 (round bar Ø20mm,rebar bar Ø16mm ), GF25(round bar Ø25mm,rebar bar Ø20mm)
- Please check if the electricity is ok, GF20 require 2.5Kw electricity at least, GF25 require 3Kw electricity at least, and please check
- Please check if the v belt is tight, v belt should be tightly much
- Please check if the machine Power Switch is on the right side
Are there any detailed instructions for the control panel? The machine rotates the way it is supposed to, but it is now stuck on that position.
Thanks Ernesto, let’s keep in touch by email
Could you help me with the electrical diagram of the sensor because my technician says it could be the fault
Hi Alejo, thanks for your message, let’s keep in touch by email
Hi…
Bought 3 GF20 machines from China, 18 months back, panel indicates 3 phase system. despite we asked for single phase system.
There is a 3 core wire Red blue and Yellow..
We made the connections with yellow as earth and red as live, and switched on the apparatus.
While pressing the pedals nothing happen. What could be wrong
