Web on a kind of H of being used for shaped steel and process the sheet-forming machine of this kind web
Technical field
The present invention relates to the web on a kind of H of being used for shaped steel and process the sheet-forming machine of this kind web.
Background technology
H shaped steel is because cross section economical rationality, superior performance, processing and fabricating and installation technology are simple, convenient, fast, become material components important in the construction steel structure system, thereby be widely used in the every field of the development of the national economy, industrial premises, the tower body equipment supporter, the steel smelting platform of metallurgy industry, high furnace frame, track etc., the coal bunker of power plant, conveying gallery etc., large-scale constructions such as land and offshore oil drilling platform, vehicle, warehouse style large supermarket, bridge tunnel all have been applied to the H shaped steel of all size, size.
H shaped steel has comprised web and frange plate, frange plate uprightly is welded on the both sides of web, web is a surface plate, prior art exists that production efficiency is low, specification is single, the shortcoming of integrated processing difficulties in processing weld type H shaped steel, the planar webs that is adopted can not be born big load, and to realize the load-bearing of big load, must increase the thickness of web or the sheet number of increase H shaped steel, like this, make cost increase greatly.
Summary of the invention
The object of the present invention is to provide that a kind of supporting capacity is strong, cost of production is low, be convenient to realize automation sheet-forming machine welding, that be used for the web on the H shaped steel and be used to process this kind web, this kind shaping machine structure is simple, the working (machining) efficiency height.The technical solution used in the present invention is: described web is the wave web, and the cross-sectional profiles line of described wave web is a curve.
Technical scheme of the present invention also has: described curve is a sine curve.
Technical scheme of the present invention also has: a kind of sheet-forming machine comprises the importation, moulding section and output, described moulding section comprises the bottom roll and the topping roll of parallel installation, described bottom roll is identical with the topping roll rotating speed, switched in opposite, and sheet material is between described bottom roll and topping roll.
Technical scheme of the present invention also has: described bottom roll comprises 3 above format rolls, the axis of described format roll is parallel with described bottom roll axis, on the cross section of described bottom roll, the center of described format roll is on the same circumference in the center of circle at the centre of gyration with described bottom roll all; Described topping roll also comprises 3 the above format rolls, and the axis of described format roll is parallel with described topping roll axis, and on the cross section of described topping roll, the center of described format roll is on the same circumference in the center of circle at the centre of gyration with described topping roll all; Described topping roll is identical with the number of format roll in the bottom roll.
Technical scheme of the present invention also has: the number of format roll is 13 in described topping roll and the bottom roll.
Technical scheme of the present invention also has: the cross section of described format roll is circular.
Technical scheme of the present invention also has: described moulding section also comprises the carry-over pinch rolls group, and described carry-over pinch rolls group is positioned at before described bottom roll and the topping roll.
Technical scheme of the present invention also has: described moulding section also comprises the thickness of slab adjusting device.
The invention has the beneficial effects as follows: H shaped steel has adopted the wave web, under the constant situation of web size constancy, thickness, the integrated carrying ability increases, the wave web in use is convenient to the realization of automation welding process, be more suitable for the construction and the construction of heavy construction steel frame construction, forming machine automaticity height, process velocity used during processing wave web are fast, both can use separately, also can supporting use on the production line of large automatic.
Description of drawings
Accompanying drawing 1 is this shaping machine structure schematic diagram, and accompanying drawing 2 is schematic diagrames of having used the H formed steel construction of wave web, wherein, the 1st, base, the 2nd, frame, the 3rd, bottom roll, the 4th, topping roll, the 5th, thickness of slab adjusting device, the 6th, format roll, the 7th, carry-over pinch rolls group, the 8th, frange plate, the 9th, web.
The specific embodiment
H shaped steel disclosed by the invention is made up of two blocks of frange plates 8 and a web 9, frange plate 8 uprightly is welded on the two ends of web 9, wherein, web 9 is wave webs, and the contour curve of its cross section is a sine curve, the sheet-forming machine of having processed this kind web 9 usefulness, sheet-forming machine is made up of importation, moulding section and output, the importation can be imported flat sheet to moulding section, sheet material can adopt manual input, also available conveyer belt automatic transport.Moulding section comprises following structure: base 1, frame 2, bottom roll 3, topping roll 4, thickness of slab adjusting device 5 and carry-over pinch rolls group 7.Wherein, base 1 and frame 2 have played supporting role, and bottom roll 3 is parallel with topping roll 4 axis, in opposite directions to rolling, rotating speed is identical, sheet material enters between bottom roll 3 and the topping roll 4 through carry-over pinch rolls group 7, has formed wave web 9 after occuring bending and deformation under the pressure effect of two rollers, when the sheet metal thickness of processing changes, regulate thickness of slab adjusting device 5, and then changed the gap length between bottom roll 3 and the topping roll 4, the wave web after the processing is exported by output.
The plum blossom roller that bottom roll 3 and topping roll 4 all are made up of a plurality of format rolls 6, the structure of each format roll 6 and measure-alike, during installation, format roll 6 is parallel with bottom roll 3 or topping roll 4 axis, on cross section, the center of all format rolls 6 on the same roll all on same circumference, in the present embodiment on bottom roll 3 or the topping roll 4 number of used format roll 6 be 13, after the processing, the curved profile of web 9 cross sections is sine curves.Output can use the collection of manually finishing the wave web, also can use conveyer belt to finish.
This forming machine was both can be separately practical, also can with the supporting use of large-scale production line.
Certainly, above-mentioned explanation is not a limitation of the present invention, and the present invention also is not limited only to above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present invention also belong to protection scope of the present invention.
