Background of This Blog on Steel Structure BOX H Beam Horizontal Press Straightening Machine:
1. Business Case: On Dec.23rd 2023, Wuxi JACK delivered a set of HJ20 Longitudinal Straightening Horizontal Press, together with a set of DX1530 BOX H Beam End Face Milling Machine, to a Belarus customer by railway transportation;
2. Significance of this Business on DX1530 BOX H Beam End Face Milling Machine and HJ20 Horizontal BOX H Beam Straightening Machine:
1) DX1530 is common seen model of BOX H Beam End Face Milling Machine in industry and market, and also superior products of Wuxi JACK, we have numerous technical advantages with it;
2) HJ20 is featured product of Wuxi JACK, which is very seldom seen in the industry, which can be produced by other companies;
3. Topics of This Blog on HJ20 Special Steel Structure BOX H Beam Straightening Horizontal Press:
A. Usage and Application of HJ Series Steel Structure BOX H Beam Straightening Horizontal Press:
1. Applicating Scenario: In Steel Structure production, workpieces usually generate deformation after large current SAW (Submerged arc welding), or long time storage, or long distance transportation, which exhibits not only workpiece cross section view flange up bend, but also deflection along its horizontal (Or longitudinal) body:
Deflected welding H Beam, which should be flattened in Longitudinal Horizontal Press Straightening Machine: (Fig.1)
2. Applicating Sites of BOX H Beam Horizontal Press Straightening Machine:
This is phenomenon not only seen in welding H Beam production, but also BOX Beam/ Section Steel, and other frequently used elongated shape metal structure working parts:

2) Straightening on H Beam in Wuxi JACK HJ20 Horizontal BOX H Beam Straightening Machine: (Fig.3)
B. Specialty of HJ Series Steel Structure Horizontal BOX H Beam Straightening Machine:
1. Uniqueness of Steel Structure BOX H Beam Straightening Horizontal Press:
1) Relative Small Selling Volume: Unlike other steel structure Straightening Machines, such as HYJ/YTJ series flange BOX H Beam Straightening Machine, and or ASM series Angle Steel Straightening Machine, which sees relatively large application in Steel Structure industry, especially the former one of flange BOX H Beam Straightening Machine, which has large using volume by customers, HJ series Horizontal BOX H Beam Straightening Machine sees relatively small using volume in markets;
2) The reasons lies behind possibly are:
a) Customers pay more attention on processing flange deformation than horizontal deflection, which is like “Must” versus “Had better”;
b) The design and manufacture on Steel Structure Longitudinal Straightening Horizontal Press is more technique orientated, which embodies technical strength of supplier company, and only small percentage of the companies have real capability on delivering high standard Horizontal Press Straightening Machine for clients;
3) Necessity: Meanwhile, when horizontal deflection grows too obvious on metal structure working parts, this becomes problem which should not be neglected by customers, and introduction on Longitudinal Horizontal Press Straightening Machine becomes a to do list;
2. Model Classification on BOX H Beam Longitudinal Horizontal Press Straightening Machine:
1) The differentiation on models of BOX H Beam Longitudinal Straightening Horizontal Press is not based on max. specification of workpieces; Instead, it is based on Max. output force from the machine;
2) For example, HJ20 refers to Max. 20 Ton straightening force, that can be delivered from hydraulic oil cylinder of the Longitudinal Straightening Horizontal Press;
3) And other 3 conventional models of the BOX H Beam Horizontal Press Straightening Machine are: HJ100/ HJ200/ HJ300;
4) Equipment Nature: In this respect, this Horizontal BOX H Beam Straightening Machine can be also viewed as a Press Machine. This is the reason that, its product name of “Longitudinal Straightening Horizontal Press” got from;
3. Operation on Steel Structure BOX H Beam Horizontal Press Straightening Machine:
1) Working Style: Longitudinal straightening along the entire length of elongated working parts in BOX H Beam Straightening Horizontal Press is not automatically and continuously running. Instead, it is in the form of segment by segment along workpieces longitudinal structure:

2) More Operator Intervention: So we can say that, productivity of this BOX H Beam Straightening Horizontal Press is “lower than” other metal structure Straightening Machine as listed above, and involves more manual job during work:
Working on HJ300 Steel Structure BOX H Beam Straightening Horizontal Press: More labor work by operators: (Fig.5)
C. Advantages and Technical Features of Wuxi JACK HJ Series Steel Structure BOX H Beam Longitudinal Horizontal Press Straightening Machine:
1. Leading Position: As an engineering based company, Wuxi JACK has outstanding performance on developing various tailor made products for customers, this includes HJ series Horizontal BOX H Beam Straightening Machine:
2. Business Achievement of Wuxi JACK HJ Series Steel Structure BOX H Beam Straightening Horizontal Press:
Over the past decades, Wuxi JACK has supplied full range of BOX H Beam Longitudinal Straightening Horizontal Press for customers worldwide, from the smallest model of HJ20, to the largest model of HJ300:
1) Nameplate of HJ20 Horizontal BOX H Beam Straightening Machine for Belarus customer this time: (Fig.6)
2) Nameplate of HJ300 Steel Structure BOX H Beam Horizontal Press Straightening Machine exported to Russia: (Fig.7)
3. Strong Points of Wuxi JACK HJ Series Horizontal BOX H Beam Straightening Machine:
1) Reasonable structure and strong intensity of mechanical main frame, which can withstand long term high strength straightening jobs on steel structure working parts, without going flimsy:
