H type steel production line equipment, in the group of vertical machine advantage
 2016-1-8  

H type steel automatic assembling machine in the machine the advantages of H-beam automatic assembling machine working principle and H type steel automatic assembling machine in the machine advantages: H-beam automatic group Li its amplitude plate wing plate positioning adopts hydraulic transmission, on both sides of by mechanical synchronous clamping of, to ensure that within the prescribed scope of different width amplitude plate, a wing plate positioning, automatic to accurately without each adjusted (with eccentric rotation micro adjustment). H type steel group pair ends with hydraulic automatic lifting of the gear rack, to ensure that the group pair amplitude plate and flange plate ends are aligned, upper pressure beam about the use of four groups of guide rail pair guide to ensure stability when pressed. According to user requirements and the length of the workpiece and reduce the number of roller any longer. Hydraulic system adopts Sino foreign joint venture enterprise standard hydraulic system products, and a fine filter, to ensure long-term reliable operation of the solenoid valve. Amplitude wing plate positioning plate adopts hydraulic transmission, on both sides of by mechanical synchronous clamping of, to ensure that within the prescribed scope of different width amplitude plate, a wing plate positioning, automatic to accurately without each adjusted (with eccentric rotation micro adjustment).

The calculation of the deflection of the 4H type steel production line is different from the H type steel production line, so the H type steel products also have different deflection. Formula for calculating the maximum deflection of span under various loads.
H-beam production line uniformly distributed load under the maximum deflection in the middle span of the beam, the formula: Ymax = 5ql^4/ 384EI. Type: Ymax for the beam cross the maximum deflection (mm). Q for all wiring standard load value kn/m. E is the elastic modulus of steel, for engineering in steel structure, e = 2.1 million N/mm^2. I for steel section moment of inertia, in the steel table check mm^4.
Cross a maximum deflection under load is concentrated in the middle span of the beam, the formula: = Ymax 8pl^3/ 384EI =1pl^3/ 48EI. Type: Ymax for the beam cross the maximum deflection (mm). P for each concentrated load standard value and (KN). E is the elastic modulus of steel, for engineering in steel structure, e = 2.1 million N/mm^2. I for steel section moment of inertia, can be in steel table check mm^4.
Inter spacing arrangement of two equal under the concentrated load, the maximum deflection in the middle span of the beam, the formula: Ymax = 6.81pl^3/ 384EI. Type: Ymax for the beam cross the maximum deflection (mm). P for each concentrated load standard value and (KN). E is the elastic modulus of steel, for engineering in steel structure, e = 2.1 million N/mm^2. I for steel section moment of inertia, can be in steel table check mm^4.
H type steel production line cross between spacing on the layout of the three equal under the concentrated load maximum deflection, the calculation formula: Ymax = 6.33pl^3/ 384EI. Type: Ymax for the beam cross the maximum deflection (mm). P for each concentrated load standard value and (KN). E for steel elastic modulus, for Engineering in steel structure, e = 2.1 million N/mm^2. I for steel section moment of inertia, can be in steel table check mm^4.
Cantilever beam under distributed load or free end and subjected to a concentrated load, the free end, respectively, the maximum deflection, the calculation formula: Ymax =1ql^4/ 8EI.; Ymax =1pl^3/ 3EI. Q for all wiring load standard value kn/m.; P for each concentrated load standard value and (KN).
According to the maximum deflection control 1/400, the load condition 25kn/m and some other load conditions are calculated, to see the upper part of the load to be met
