A: Advantages of H-beam automatic assembly machine in the assembly machine working principle of H-beam automatic assembly machine and advantages of H-beam automatic assembly machine in the assembly machine: H-beam automatic assembly machine adopts hydraulic transmission for plate and wing plate positioning, and both sides are mechanically clamped and aligned synchronously, which can ensure the plate and wing plate positioning of different widths within the specified range, automatic alignment is accurate, and it does not need to be adjusted every time The eccentric wheel is set for micro adjustment. When H-beam is assembled, the end of H-beam is equipped with a hydraulic automatic lifting material retaining frame, which can ensure the alignment of the end of frame plate and wing plate. The upper pressure beam is guided by four pairs of guide rails to ensure the stability during compression. It can lengthen and reduce the number of roller table according to the user's requirements and workpiece length. The hydraulic system adopts the standard hydraulic system products of Sino foreign joint venture, and is equipped with fine filter to ensure the long-term reliable operation of solenoid valve. Hydraulic transmission is adopted for the positioning of the width plate and wing plate, and the two sides are clamped and aligned by mechanical synchronization, which can ensure the positioning of the width plate and wing plate within the specified range, and the automatic alignment is accurate, and there is no need to adjust each time (with eccentric wheel for micro adjustment).

The calculation of deflection of 4H steel production line is different from that of H steel production line, so H steel products have different deflections. The calculation formula of mid span deflection under various loads.
 
The deflection of H-beam production line under uniform load is in the middle of the beam span. The calculation formula is: ymax = 5ql ^ 4 / (384ei). Where, ymax is the deflection in the middle of the beam span (mm). Q is the standard value of uniform load (KN / M). E is the elastic modulus of steel. For structural steel used in engineering, e = 2100000 n / mm ^ 2. I is the section moment of inertia of steel, which can be found in the section steel table (mm ^ 4)
 
The calculation formula of the deflection under a concentrated load in the middle of the span is: ymax = 8pl ^ 3 / (384ei) = 1pl ^ 3 / (48ei). Where, ymax is the deflection in the middle of the span (mm). P is the sum of the standard values of each concentrated load (KN). E is the elastic modulus of the steel. For the structural steel used in engineering, e = 2100000 n / mm ^ 2. I is the section moment of inertia of the steel, which can be found in the section steel table (mm ^ 4)
 
The deflection under two equal concentrated loads arranged at equal intervals between spans is in the middle of the beam span. The calculation formula is: ymax = 6.81pl ^ 3 / (384ei). Where, ymax is the large deflection in the middle of the beam span (mm). P is the sum of the standard values of each concentrated load (KN). E is the elastic modulus of the steel. For structural steel used in engineering, e = 2100000 n / mm ^ 2. I is the section moment of inertia of the steel, which can be found in the section steel table (mm ^ 4)
 
The calculation formula of the deflection of H-beam production line under three equal concentrated loads with equal spacing is ymax = 6.33pl ^ 3 / (384ei), where ymax is the deflection of beam span (mm), P is the sum of standard values of each concentrated load (KN), e is the elastic modulus of steel, E = 2100000 n / mm ^ 2 for engineering structural steel, and I is the section moment of inertia of steel, which can be found in the section steel table (mm ^ 4)
 
When the cantilever beam is subjected to uniform load or concentrated load at the free end, the deflection at the free end is respectively, and the calculation formula is: ymax = 1ql ^ 4 / (8ei);; ymax = 1pl ^ 3 / (3ei). Q is the standard value of uniform load (KN / m); P is the sum of the standard values of various concentrated loads (KN)
 
According to the deflection control of 1 / 400, the load condition of 25kn / M and some other load conditions, the inverse calculation can be carried out to see the upper load requirements that can be met.
