Description
Technical field
The utility model relates to Flat-bulb steel rolling device, is specifically related to a kind of closed pass structure of flat-bulb steel web straight flange.
Background technology
Flat-bulb steel is shipbuilding industry special-purpose section, flourish due to domestic shipbuilding industry, to the demand also corresponding increase of flat-bulb steel, flat-bulb steel becomes key product and the high margined item of each steel mill, the quality of flat-bulb steel quality, directly affects the market image of steel mill, affects occupation rate of market.
Flat-bulb steel generally adopts solder technology in producing, solder technology is the main technology of shipbuilding engineering, be the support of modern shipbuilding pattern, it has the meaning that speed of production is fast, yield rate advantages of higher, particularly robot welding have particular importance for shipbuilding.In shipbuilding process, meet shortening production cycle by robot welding means, reduce the demand of construction cost, ensure good welding quality simultaneously.But also improve for the requirement of flat-bulb steel, the production of current flat-bulb steel, perforate pass is taked at welding edge position thereupon, allow R angle freely stretch and cause R angle radian excessive, the requirement of robot welding can not be met.
Utility model content
For the problems referred to above, the utility model provides the closed pass structure of flat-bulb steel web straight flange, its object is to: solve flat-bulb steel welding edge R angle circular arc problems of too, thus meet the requirement of robot welding, improves enterprises production efficiency and the quality of production.
Technical solution of the present utility model:
The closed pass structure of flat-bulb steel web straight flange, it is characterized in that: comprise flat-bulb steel pass, topping roll flat-bulb steel welding edge, bottom roll flat-bulb steel welding edge, bottom roll wallboard, topping roll wallboard, flat-bulb steel web, flat-bulb steel bulb, bottom roll wallboard, topping roll, bottom roll, flat-bulb steel pass is formed between described topping roll and bottom roll, flat-bulb steel pass is made up of flat-bulb steel bulb and flat-bulb steel web, topping roll flat-bulb steel welding edge and bottom roll flat-bulb steel welding edge close proximity, closed pass is formed to flat-bulb steel web, topping roll wallboard is stuck between bottom roll wallboard, when producing flat-bulb steel, rolled piece is through flat-bulb steel pass and complete and be full of pass, topping roll flat-bulb steel welding edge and bottom roll flat-bulb steel welding edge stop flat-bulb steel web freely not stretch, formation can meet the straight flange of robot welding.
Described topping roll wallboard is stuck between bottom roll wallboard, effectively limit the transverse shifting of topping roll and bottom roll, during milling train work simultaneously, likely vertical tremor, topping roll flat-bulb steel welding edge and bottom roll flat-bulb steel welding edge effectively can be avoided mutually to collide, cause the damage of flat-bulb steel pass.
The beneficial effects of the utility model:
By actual production rolling, this utility model structure can produce the flat-bulb steel that welding edge is straight flange, the requirement of robot welding flat-bulb steel can be met, greatly improve the efficiency of construction of boats and ships, save welding material, ensure the quality of welding, also successfully upgrade the production technology of flat-bulb steel, the quality of product is improved significantly.
Accompanying drawing explanation
Fig. 1: the utility model structural principle schematic diagram.
Wherein: 1 flat-bulb steel pass 2 topping roll flat-bulb steel welding edge 3 bottom roll flat-bulb steel welding edge 4 bottom roll wallboard 5 topping roll wallboard 6 flat-bulb steel web 7 flat-bulb steel bulb 8 bottom roll wallboard 9 topping roll 10 bottom roll.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further:
The closed pass structure of flat-bulb steel web straight flange as shown in Figure 1, comprise flat-bulb steel pass 1, topping roll flat-bulb steel welding edge 2, bottom roll flat-bulb steel welding edge 3, bottom roll wallboard 4, topping roll wallboard 5, flat-bulb steel web 6, flat-bulb steel bulb 7, bottom roll wallboard 8, topping roll 9, bottom roll 10, flat-bulb steel pass 1 is formed between described topping roll 9 and bottom roll 10, flat-bulb steel pass 1 is made up of flat-bulb steel bulb 7 and flat-bulb steel web 6, topping roll flat-bulb steel welding edge 2 and bottom roll flat-bulb steel welding edge 3 close proximity, closed pass is formed to flat-bulb steel web 6, topping roll wallboard 5 is stuck in the middle of bottom roll wallboard 4 and 8, when producing flat-bulb steel, rolled piece is through flat-bulb steel pass 1 and complete and be full of pass, topping roll flat-bulb steel welding edge 2 and bottom roll flat-bulb steel welding edge 3 stop flat-bulb steel web 6 freely not stretch, formation can meet the straight flange of robot welding, due to rolling carry out being full of pass to flat-bulb steel 7 and flat-bulb steel web 6 in flat-bulb steel pass 1 time, roll transverse shifting can be caused, and topping roll wallboard 5 is stuck in the transverse shifting effectively limiting topping roll 9 and bottom roll 10 between bottom roll wallboard 4 and bottom roll wallboard 8, during milling train work simultaneously, likely vertical tremor, topping roll flat-bulb steel welding edge 2 and bottom roll flat-bulb steel welding edge 3 can be effectively avoided mutually to collide, cause the damage of flat-bulb steel pass 1.
The formation of the straight flange of the welding of flat-bulb steel depends on the fore shaft position of flat-bulb steel pass, the utility model mainly by the fore shaft of flat-bulb steel pass by the original open pass that welding edge can be allowed freely to stretch, change to the closed pass not allowing welding edge freely stretch, in the passage that rolling flat-bulb steel is last, rolled piece can be full of pass, closed pass passage fore shaft position can limit the welding edge of flat-bulb steel effectively, makes the formation of the straight flange of welding edge.
Two wallboards are increased to flat-bulb steel pass bottom roll two, i.e. topping roll wallboard and bottom roll wallboard, prevent roll from laterally jumping, ensure the elasticity of closed pass, prevent two rolls to collide damage pass simultaneously.
To sum up, the utility model accomplishes the end in view.
