According to the embodiment of the utility model, the distance between the wing plates on two sides inboard (h2) can be 184 ± 0.75mm.
According to the embodiment of the utility model, wing plate inboard with the web inboard between transition can be to comprise originating in the first inboard arc transition of web, originating in second arc transition of wing plate inboard and the smooth transition of the straight line slope transition that first arc transition is connected with second arc transition.
According to the embodiment of the utility model, point that straight line slope place straight-line extension and wing plate intersect and the distance (e) between the web can be 5mm, and the straight line slope belongs to point that straight-line extension and web intersect and the distance (f) between the wing plate can be 20mm; The radius of first arc transition (Ra) can be 50mm; The radius of second arc transition (Rb) can be 8mm.
According to the embodiment of the utility model, the outside top angle of wing plate can be that radius (Rc) is the circular arc of 3mm.
According to the embodiment of the utility model, the exterior bottom angle of wing plate can be that radius (Rd) is the circular arc of 8mm.
The large-tonnage fork truck that can be used for 8～10t according to the channel-section steel that is used for forklift door frame of the utility model.In addition, stable according to the channel-section steel that is used for forklift door frame of the utility model, intensity is high, and can produce in batches through whole hot-roll forming.
Description of drawings
Through the description of embodiment being carried out below in conjunction with accompanying drawing, above-mentioned and/or other purposes and the advantage of the utility model will become apparent, wherein:
Fig. 1 is the schematic cross sectional views according to the structure of the channel-section steel that is used for forklift door frame of the utility model exemplary embodiment.
Embodiment
With specific embodiment the channel-section steel that is used for forklift door frame according to the utility model is carried out detailed description below with reference to accompanying drawings.
Fig. 1 is the schematic cross sectional views according to the structure of the channel-section steel that is used for forklift door frame of the utility model exemplary embodiment.
With reference to Fig. 1, comprise web 1 and wing plates on two sides 2 through whole hot-roll forming according to the channel-section steel that is used for forklift door frame of the utility model exemplary embodiment.That is, according to channel-section steel once-through of the utility model exemplary embodiment through whole hot rolling.Therefore, according to the channel-section steel of the utility model and the channel-section steel that forms through welding high, the structural stability of specific strength mutually, and can produce in batches and improve the utilization ratio and the manufacturing efficiency of metal.According to present embodiment; Distance between wing plates on two sides 2 outsides of channel-section steel (that is, the cross section outside width of channel-section steel) h1 is 244mm, and the inboard of wing plate 2 and the thickness between the outside are (promptly; The thickness of wing plate 2) c is 30 ± 1.0mm; Distance between the bottom of wing plate 2 to the top (that is, the height of wing plate 2) b is 67 ± 1.0mm, and the thickness of web (d) is 20 ± 0.8mm.Channel-section steel with above-mentioned parameters is stable, intensity is high and can be used for the door frame of the large-tonnage fork truck tackling system of 8～10t.
According to the utility model exemplary embodiment, the distance h 2 between wing plates on two sides 2 inboards can be 184 ± 0.75mm.
According to the exemplary embodiment of the utility model, wing plate 2 inboard with web 1 inboard between transition be to comprise originating in web 1 inboard first arc transition, second arc transition that originates in wing plate 2 inboards and the smooth transition of the straight line slope transition that first arc transition is connected with second arc transition.That is the circular arc that, adds smooth transition between web 1 and the wing plates on two sides 2 for skew lines.According to the exemplary embodiment of the utility model, can be 5mm apart from e between point that straight line slope place straight-line extension and wing plate 2 intersect and the web 1, the straight line slope belongs to and can be 20mm apart from f between point that straight-line extension and web 1 intersect and the wing plate 2; The radius R a of first arc transition can be 50mm; The radius R b of second arc transition can be 8mm.This structural channels helps improving the intensity of channel-section steel, and helps improving the stability of roller operation.
