The technical scheme of the present invention is: it comprises upper side, lower sealing surface and left and right cambered surface, and left and right cambered surface is connected with upper side, lower sealing surface respectively, forms a kind of closed hollow material.
Described section bar arranges at least one and is mutually engaged extruded interface by the first U-shaped mouth with the 2nd U-shaped mouth.
Described interface arranges impression and limiting displacement section.
Described section bar upper side be plane or or cambered surface, or be the trench structure face inside or outside relative to die cavity.
Described section bar upper side arranges extruding lines or at least one stiffening web inside or outside relative to die cavity.
Under described section bar, sealing surface arranges at least one strengthening groove inside or outside relative to die cavity.
Described strengthening groove arranges at least one-level step.
The left and right cambered surface of described section bar at least arranges connection face and is connected with upper side or lower sealing surface in one end.
Described connection face is plane or cambered surface.
The left and right cambered surface of described section bar arranges extruding lines or at least one stiffening web inside or outside relative to die cavity.
High strength provided by the invention exempts to weld abnormity section bar, is mutually extruded cavity be engaged and being formed and close by the first U-shaped mouth and the 2nd U-shaped mouth, it is not necessary to welding, it is to increase production efficiency, and nothing welds the generation of flue dust, more environmental protection; Arranging impression and limiting displacement section at the first U-shaped mouth mouth place of occlusion U-shaped with the 2nd, interface occlusion is firm, good stability simultaneously; Under section bar, sealing surface arranges strengthening groove, and each side arranges stiffening web and extruding lines, profile structure intensity height.

Description of symbols in figure: upper side 1, lower sealing surface 2, interface 3, left and right cambered surface 4,4 ', strengthening groove 5, trench structure face 6, stiffening web 7, extruding lines 8, stiffening web 9, step 10, die cavity 11, the U-shaped U-shaped mouth 32 of mouth the 31, two in connection face 12,12 ', the first, limiting displacement section 33, impression 34.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the present invention is further described, it will be appreciated that preferred embodiment only in order to the present invention is described, instead of in order to limit the scope of the invention.
As shown in Fig. 1 ~ 6, a kind of high strength is exempted to weld abnormity section bar, and it comprises upper side 1, lower sealing surface 2 and left and right cambered surface 4,4 ', and left and right cambered surface 4,4 ' is connected with upper side 1, lower sealing surface 2 respectively, forms a kind of closed hollow material.
As shown in Fig. 1 ~ 6, under section bar, sealing surface 2 arranges and mutually extrudes, by the first U-shaped mouth 31 mouth 32 U-shaped with the 2nd, the interface 3 being engaged, and product moulding is without the need to welding, it is to increase production efficiency, and avoids the generation of welding flue dust, more environmental protection; Interface 3 is provided with impression 34 and limiting displacement section 33, and occlusion structure is more stable, and not easily pine is de-, enhances the stability of section bar, and interface 3 is formed by the occlusion of multilayer material ruffle, further enhancing section bar intensity.
As shown in Fig. 1,3,4, the trench structure face 6 that section bar upper side 1 is inside relative to die cavity 11, further, upper side 1 arranges extruding lines 8 or the stiffening web 7 inside relative to die cavity 11, the structural strength of reinforcing profile and stability.
As shown in Fig. 1,4,5,6, under section bar, sealing surface 2 arranges a strengthening groove 5 inside relative to die cavity 11, enhances profile structure intensity and stability; Further, as shown in Figure 3, strengthening groove 5 arranges step 10, and profile structure intensity and stability improve further.
As shown in Fig. 1,3,4, the left and right cambered surface of section bar 4,4 ' two ends are connected with upper side 1, lower sealing surface 2 respectively, left and right cambered surface 4,4 ' arranges the stiffening web 9 inside relative to die cavity 11, section bar anti-side face impact capacity is stronger, when being subject to external impact or extruding, stiffening web can effectively disperse outside surging force or squeeze, and profile structure is more stable.
