1. Function: HJ model BOX H Beam Lateral Straightening Machine is an important product branch of H Beam Straightening Machine, for performing straightening lateral deformation of H/ BOX Beam / Welding steel structure member along length direction;
1) Multi-Function: Unlike HYJ and YTJ series Flange H Beam Straightening Machine, which is specifically being applied for straightening H Beam flange deformation, this Horizontal Press Straightening Machine can be used on wide variety types of steel structure workpieces: H/ BOX Beam; Section Steel; Channels, etc.;
1) Working Nature: This Horizontal Press Straightening Machine is in essence a kind of hydraulic drive Working Press;
2) Its acting unit is a piece of oil cylinder drive ram which moves in horizontal direction, pushing workpiece into plastic deformation of opposite direction, thus acquiring purpose of straightening;
3) Straightening Stroke Management: To precisely manage on lateral movement straightening stroke of the ram, there is a measuring ruler equipped in working unit of the steel structure BOX H Beam Lateral Straightening Machine, to control straightening volume on workpieces:
1) Straightening Style: Correspondingly, in this length direction H Beam Straightening Machine, straightening is carried out in the form of step by step lateral pushing;
2) Which means, at the completion of current segment straightening, the workpiece is pushed forward manually for next segment straightening;
3) Workpiece Sending Forward: In this respect, although there are input and output conveyor to be equipped with the Welding Steel Structure BOX H Beam Lateral Straightening Machine, its conveyors majority conditions work in the mode of manual acting, instead of motor drive. Especially its output conveyor;
1) Depending on length and cross section size of workpiece, the length of straightening segment in Horizontal Press Straightening Machine can be adjusted in the range of 1500mm to 2000mm;
2) This means, every time straightening action in this H Beam Straightening Machine can fulfill 1500mm to 2000mm length of workpiece body;
3) The adjustment on this working zone length is realized with 2 pieces of holding points, which also serve as straightening force bearing points in the H Beam Straightening Machine:
1) The differentiation on models of Welding Steel Structure BOX H Beam Lateral Straightening Machine is based on its max. output straightening force, from 20 ton (Model: HJ20) to 200 Ton (HJ300);
2) Other common used models include: HJ100/ HJ200/ HJ250;
Composition: This Welding Steel Structure BOX H Beam Lateral Straightening Machine is composed of mechanical main frame/ Input conveyor/ Output conveyor/ Hydraulic system and electric control system:
1) The main components include: Stationary working bed/ Acting pressing beam/ Straightening use cylinder / Supporting roller tables;
2) Straightening drive cylinder is fixed onto horizontal beam. Its movement is guided with piston rod, during straightening pressing in the Welding Steel Structure BOX H Beam Lateral Straightening Machine;
3) The 2 pieces of straightening force blocks are installed at front face of pressing beam. Its secured interval positions can be adjusted manually. This interval equals to single time straightening length in the Horizontal Press Straightening Machine. After adjustment, the 2 blocks are secured manually with screws;
4) To avoid conflict between workpiece and the 2 force blocks during workpiece sending in, there are 2 pieces of positioning cylinders equipped in the Horizontal Press Straightening Machine, which has 1335mm interval between each other. These 2 positioning cylinders can push workpiece away from the 2 force blocks when necessary;
1) Input and output conveyors are for sending in and out of workpiece respectively;
2) Both the conveyors consist of driving and idle roller tables;
3) Infeed and outfeed roller tables all have 8,000mm length;
4) Outfeed roller table is driven with motor reducer;
1) Function: Hydraulic system is for pushing and clamping workpiece firmly;
2) Equipped with intake and pressure filters: One filter works during commissioning; The other filter manages on official running of the Welding Steel Structure BOX H Beam Lateral Straightening Machine;
3) Main components of hydraulic system include: Pump station/ Straightening purpose and Positioning purpose cylinders/ hose;
4) Long service life: Equipped with fine filter, hydraulic system makes sure long term reliable running of the Welding Steel Structure BOX H Beam Lateral Straightening Machine.
Taking H Beam as Example:
1) Flange Width b: From (100 ~ 200 mm) for HJ20 to (200 ~ 800 mm) for HJ300
2) Flange Thickness s:From (6 - 15 mm) for HJ20 to (6 - 40 mm) for HJ300
3) Web Height h:From (100 – 400 mm) for HJ20 to (200 – 600 mm) for HJ300
4) Web Thickness a:From (5 – 7 mm) for HJ20 to (6 – 30 mm) for HJ300
5) H Beam Length: 3,000 – 12,000 mm
