Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Referring to Fig. 1 to Fig. 3, wherein Fig. 1 is the truck doorframe integral structure schematic diagram the utility model proposes; Fig. 2 is the truck doorframe cross sectional drawing the utility model proposes; Fig. 3 is the truck doors mount structure front elevation the utility model proposes.
As shown in Figure 1 to Figure 3, the utility model provides a kind of truck doorframe, this truck doorframe is trapezium structure, right-end openings, it is characterized in that: described doorframe is formed by a steel band, described steel band, by being folded to form boss and trimming 1, is also provided with auxiliary hole 2, solder joint 3 and assembly opening 4 on described doorframe.
Described steel band adopts flow forming technology to amount to into three-decker, as shown in Figure 2, the cross-sectional plane of described steel band is the compound section 6 of both ends open, described section 6 is notch, steel band starts from draw-in groove inside to form projection to the upper end of draw-in groove, then arrive the other end of draw-in groove, the bottom of going back to draw-in groove forms and reinforces groove.Cross dimensions is stable, sound construction, and section adopts roll welding technology to reinforce simultaneously.
Described steel band forms steel band by three-dimensional bending technology the trapezium structure of one end opening.
Described boss and trimming 1 adopt stamping technology to form, and meet doorframe matching requirements, and while ensureing assembling, door-plate bound edge is smooth.
Described auxiliary hole 2 is located and is formed by punching press in the time of bending.
Described solder joint 3 is arranged on the left side of auxiliary hole 2, adopts roll welding technology to weld, and solder joint is even, and error is little, and without welding slag, weld strength is high.
Described assembly opening 4 is that one-step punching is shaped in the time of bending, completes together with bending forming, so hole position error is little, is out of shape little.
Described doorframe rear side tail end is radian trimming 5, adopts the die-cut technology of advanced radian, disposable die-cut completing.Burr is little, and die-cut distortion can be controlled less.
This truck doorframe adopts Baosteel SPCC, T0.8mm steel band, and machinery is high, and easy-formation, is difficult for getting rusty.The three-dimensional radian of entirety adopts domestic advanced person's three-dimensional bending technology, and bending substantially without distortion, resilience is few.Bend angle is smooth and easy, with car door panel beating good fit.
