Wuxi JACK Strength on Developing Various Types of H Beam Straightening Machine for Customers
A. Working Capacity of the 3 sets of Heavy duty Hydraulic H Beam Flange Straightening Machine:
1. Brief on the H Beam Flange Straightening Machine:
The 3 sets of machine all belongs to YTJ series hydraulic driving style, in the models of:
YTJ-40/ YTJ-60/ YTJ-80: Available Max. flange thickness for straightening is 40mm/ 60mm/ 80mm respectively, fabricated from 600MPa tensile strength carbon steel (Chinese grade Q345-B);
2. Busy On Site Working of the 3 sets of Wuxi JACK YTJ Series hydraulic Heavy duty H Beam Flange Straightening Machine: (Fig.1)
3. The Super Strong Straightening Capacity of Hydraulic H Beam Straightening Machine:
1) You may know that, in product family of H Beam Flange Straightening Machine, the discrimination on models is on the basis of material strength and flange thickness, instead of H Beam size (Web height);
2) This is because mechanical main body of all H Beam Flange Straightening Machine is with open structure, which has no restriction on web height of the welding H Beam which pass through;
3) Structure of Wuxi JACK YTJ80 model heavy duty machine and its workpiece H Beam passing through: (Fig.2)
4) Instead, the material tensile strength and max. thickness of flange that can be straightened, is the foremost criterion on judging ability of any set of H Beam Flange Straightening Machine;
5) In this respect, YTJ series, especially YTJ-80 is the largest model and the most powerful product in the whole group of H Beam Straightening Machine. Let us make an analysis and comparison:
a) Tensile strength of carbon steel: 600 MPa for YTJ series hydraulic, versus 370~ 510 MPa for HYJ series mechanical motor drive machine for H Beam straightening;
b) Max. Thickness of Flange: 40mm/ 60mm/ 80mm for the 3 sets of YTJ series hydraulic, versus 40mm for HYJ series motorized type;
4. Application Field of YTJ series Hydraulic H Beam Straightening Machine:
1) Generally speaking, these 3 sets of YTJ equipment are Heavy duty H Beam Straightening Machine, which is used for building up super heavy Steel Structure Construction Project, such as Cross Sea Bridge;
2) Comparatively, HYJ series mechanical motor drive machine belongs to conventional type, which can meet majority of practical application demand, and sees more use.
B. Technical View on Heavy duty Hydraulic H Beam Straightening Machine:
These Heavy duty machine for H Beam straightening has compact structure, high strength, and strong intensity, which is composed of:
1. Main Motor Reducer: Power 15kW ~ 22kW, delivering driving torque of 48650N.m ~ 69650 N.m.;
2. Main transmission rollers;
3. Straightening System and Straightening Rollers of Heavy duty Hydraulic H Beam Flange Straightening Machine:
1) Straightening rollers are forged into shape from 35CrMo, in hardness HRC50-55, ensuring its long term intact usage, without defects such as cracks;
2) 35CrMo has high standard intensity/ toughness/ hardenability, which is used as raw materials of large cross section gear/ heavy duty transmission shaft/ Herringbone gear in Rolling Mill/ High power motor shaft/ Turbine generator main shaft;
3) Main straightening rollers of Wuxi JACK YTJ80 series Heavy duty hydraulic H Beam Straightening Machine: (Fig.3)
4. Hydraulic System Oil Cylinders for Driving Elevation of Main Rollers: Power of its oil pump driving motor is 11kW to 15kW, with rated pressure of 25MPa;
5. Web Clamping Units in YTJ Series Heavy duty Hydraulic H Beam Straightening Machine:
1) During straightening, web of welded H Beam is clamped with alignment rollers;
2) Based on different flange width of H Beam, the distance and horizontal position of these alignment rollers can be adjusted laterally, driven with hydraulic oil cylinders;
3) Web clamping unit in Wuxi JACK YTJ series Heavy duty Hydraulic H Beam Straightening Machine: (Fig.4)
6. Mechanical Main Frame and Base Bed of YTJ Series Heavy duty Hydraulic H Beam Flange Straightening Machine:
1) Its mechanical main body has relative low height, keeping the best degree of gravity center stability;
2) Open structure, accommodating H Beam of any web height passing through; without limitation
3) Mechanical main body and pedestal of Wuxi JACK YTJ80 model Heavy duty Hydraulic H Beam Flange Straightening Machine: (Fig.5)
7. Input and Output Conveyor of YTJ Series Heavy duty Hydraulic H Beam Flange Straightening Machine:
1) Input and output conveyors have its independent driving motor reducers, of 2.2kW power respectively;
2) Input and output conveyors have the same consistent speed, which is also straightening working speed of the machine;
3) Input and output conveyors of Wuxi JACK YTJ80 model Heavy duty Hydraulic H Beam Straightening Machine: (Fig.6)
8. Hydraulic System of YTJ Series Heavy duty H Beam Flange Straightening Machine:
1) Independent pump station, which is put alongside main body and electric control board of the machine;
2) Hydraulic pump station of Wuxi JACK YTJ80 model hydraulic H Beam Straightening Machine: (Fig.7)
9. Electric Control System of YTJ Series Heavy duty Hydraulic H Beam Flange Straightening Machine:
1) Independent floor standing type control board, integrated with operating panel on its top, put alongside main body of the machine;
2) Electric control board and operating panel of YTJ80 model hydraulic H Beam Straightening Machine: (Fig.8)
