Description

A kind of nuclear power station Leak-tight liner reinforcement section molding machine

Technical field

The utility model patent is related to a kind of steel plate forming method, and especially a kind of Leak-tight liner reinforces section forming method, belongs to In " nuclear power station steel structure construction technology field ".

Background technique

Leak-tight liner is largely be made of bottom plate, the truncated cone, cylinder and dome four one by steel plate and section steel manufacture Seal casinghousing is a part of nuclear power plant containment shell, is the key that one of security perimeter of nuclear island, it is played prevents under extreme accident The effect of nuclear leakage.

Leak-tight liner reinforces the coupling part that section is bottom plate and the truncated cone, the truncated cone and cylinder.Its Forming Quality directly affects The installment work of coupled part.Leak-tight liner, which reinforces section, has certain interior dog-ear a1 and outer dog-ear b1, referring to Fig. 5 institute Show, existing processing method is that first punching press respectively has half of reinforcement section (101 and 102) on an inclined-plane, then by the reinforcement of two halves It is welded into an entirety after section splicing, wherein 103 be weld seam, is detailed in Fig. 6.

Welding is docked using traditional manual electric arc welding, but (it is big that its welded section accounts for total section to its welding capacity greatly Small 8%, and general Leak-tight liner and welding for steel structure amount only account for the 0.1 ~ 1% of total section, reinforce every 24 sections of the circle point of section, need It is spliced into whole circle), welding efficiency and welding quality are larger for artificial factor dependence, it is easy to generate in the welding process Welding defect and deformation, are not easy to guarantee quality, while inefficiency.

Summary of the invention

Technical problem to be solved in the utility model is in view of the deficiency of the prior art, and to provide a kind of nothing Operation need to be welded, so that the Leak-tight liner for significantly improving work efficiency and forming quality reinforces section molding machine.

In order to solve the above technical problems, the technical solution adopted in the utility model is:

First equipment is bending machine, including upper die and lower die；Angle between two inclined-planes of the upper mold is 185°~270°；Angle between two inclined-planes of the lower die is 90 ° ~ 175 °.

The third equipment is bending machine, including interior roller and outer roller, and the rotation direction of the interior roller and outer roller is opposite；It is described Interior roller has ridge outer edge surface, and the angle of the ridge outer edge surface, which is less than, reinforces 1 °~5 ° of infolding face angle degree of section；The outer roller tool Have with two inclined-planes reinforcing saving outer folding face and matching, the angle on two inclined-planes be greater than reinforce saving be folded outward 1 ° of face angle degree~ 5°。

The angle of the ridge outer edge surface, which is less than, reinforces 2 ° of infolding face angle degree of section；The angle on two inclined-planes, which is greater than, to be reinforced outside section 2 ° of folding face angle.

Second equipment is milling machine.

Compared with prior art, the utility model forms an entirety to the machining of steel plate by three equipment The Leak-tight liner of structure reinforces section, and overall process is without welding during reinforcing section production；Oblique surface machining, processing essence are carried out using milling machine Degree is high, accurate positioning；Reduce environmental pollution, the process-cycle is short.
