Answer: the working principle of the H type steel automatic set up machine in the group stand machine and the advantage of the H type steel automatic set up machine and the advantage of the H type steel automatic set up machine in the set up machine: H type steel automatic set up machine its amplitude plate wing plate positioning using hydraulic transmission, both sides through mechanical synchronous clamping, can ensure the range of different width of the width plate The position of the wing plate is accurate, and there is no need to adjust every time. The H Steel Group has a hydraulic automatic lifting gear frame on the time end, which can ensure the alignment of the time plate and the end of the wing plate. The upper pressure beam is guided by the left and right four groups of guide pairs to ensure the stability of the press. It can be arbitrarily lengthened according to user requirements and length of work pieces and reduce the number of roller tables. The hydraulic system adopts the product of the standard hydraulic system of the Sino foreign joint venture, and has a fine filter to ensure the long-term reliable operation of the solenoid valve. The plate wing plate positioning using hydraulic transmission, both sides through mechanical synchronous clamping, can ensure the range of different width of the width of the plate, wing plate positioning, automatic correct, no adjustment every time (with eccentric rotation with micro adjustment). The H Steel Group has a hydraulic automatic lifting gear frame on the time end, which can ensure the alignment of the time plate and the end of the wing plate. The upper pressure beam is guided by the left and right four groups of guide pairs to ensure the stability of the press. It can be arbitrarily lengthened according to user requirements and length of work pieces and reduce the number of roller tables. The hydraulic system adopts the product of the standard hydraulic system of the Sino foreign joint venture, and has a fine filter to ensure the long-term reliable operation of the solenoid valve.

The calculation of the deflection of the 4H steel production line is different from that of the H steel production line, so the H steel products also have different deflections. The calculation formula of maximum deflection under different loads is derived.

The maximum deflection of the H steel production line under uniform load is in the span of the beam. The formula is Ymax = 5ql^4/ (384EI). Ymax is the maximum deflection (mm) in the beam span. Q is the standard value (kn/m) of the uniform wiring load (kn/m). E is the elastic modulus of steel. For engineering structure steel, E = 2100000 N/mm^2. I is the section inertia of steel, which can be found in the steel sheet. It is (mm^4).

The maximum deflection under a central load is in the span of the beam: Ymax = 8pl^3/ (384EI) =1pl^3/ (48EI). The maximum deflection (mm) in the beam span is Ymax (mm). P is the sum of the standard values of each concentrated load (KN). E is the elastic modulus of steel, and the section inertia of steel, E = 2100000 N/mm^2., can be used for the section of steel. Mm^4 is found in the steel sheet.

The maximum deflection under the interspace equidistance is arranged in the span of the beam under two equal concentrated loads. The formula is Ymax = 6.81pl^3/ (384EI). Ymax is the maximum deflection in the beam span (mm). P is the sum of the standard values of each concentrated load (KN). E is the elastic modulus of steel, for engineering structural steel, E = 2100000 N/mm^2. I is the section of steel. The surface moment can be found in the form of the steel sheet (mm^4).

The maximum deflection of H steel production line interspace between three equal concentrated loads, Ymax = 6.33pl^3/ (384EI). In the formula: Ymax is the maximum deflection in the beam span (mm). P is the sum of the standard values of all concentrated loads (KN). E is the elastic modulus of steel, for engineering structure steel, E = 2100000 N/mm^2. I is the section of steel. The surface moment can be found in the form of the steel sheet (mm^4).

The maximum deflection of the free end when the cantilever beam is loaded by the uniform load or the free end is subjected to the concentrated load. The formula is Ymax =1ql^4/ (8EI). Ymax =1pl^3/ (3EI). Q is the standard load standard value (kn/m). P is the sum of the standard values of the various concentrated loads (KN).

According to the maximum deflection control 1/400, load condition 25kn/m and some other load conditions, we can calculate the upper load that can be satisfied.
