Preferred according to the utility model, described the first wing plate, the second wing plate and the 3rd wing plate and web joint are set to seamlessly transit.The advantage of this kind of design is, joint is smoothed curve transition to be made stressed more evenly, and integrally bending stress and local stress numerical more tend to balance, and safety coefficient improves.
Preferred according to the utility model, the cross section of described the first wing plate, the second wing plate, the 3rd wing plate is rectangle, the thickness ratio of the first described wing plate, the second wing plate, the 3rd wing plate and web is 1:1～1.5:1, and the lenth ratio of the first wing plate, the second wing plate, the 3rd wing plate and web is 1:2.5～1:3.5.The Thickness Ratio of wing plate of the present utility model and web and Length Ratio are the thickness of diameter according to roller, roller and regioselective, overcome the wing plate shaped steel short defect in working life causing easy to wear, the thickness ratio of the utility model wing plate and web, that relevant professional workforce passes through long-term research and gropes to obtain according to the wearing and tearing of shaped steel and working life, make the wing plate of shaped steel more wear-resistant, extended the working life of shaped steel, save material simultaneously, reduce costs, improved fork truck bearing capacity simultaneously.
The beneficial effects of the utility model are:
1. the every dimensional parameters of the utility model is extremely stable, can be used for the manufacture of all kinds of forklift door frames.
2. the place of seamlessly transitting that is connected inner side at the second wing plate with web has increased projection design, can increase structural rigidity on the one hand, improve bearing capacity, also be conducive on the other hand the guiding of door frame roller, wing plate, web, wing plate and the distortion of web joint of having avoided existing welding to cause, and wing plate and web joint sealing-off, strengthened the rigidity of J shaped steel.
3. this shaped steel design that is structure as a whole, by hot rolling once-through, can realize batch production and the supply of material, and manufacturing efficiency and using rate of metal obviously improve.
4. use this shaped steel to manufacture forklift door frame, can shorten fork truck manufacturing enterprise in the manufacture cycle of manufacturing forklift door frame, cost of production significantly reduces.
