Abstract
The utility model discloses an engineering-truck rim shaped steel. The cross section of the shaped steel is provided with a straight segment matched with a tire; one end of the straight segment is bent upward vertically and then is bent outward into an arc limit leg; the bent part connecting the limit leg and the straight segment is a smooth transition thickening segment; the other end of the straight segment is bent downward obliquely and then is bent upward and inward into a thickening hook segment; and the internal surface of the hook segment is surrounded into a trim-strip groove. The rim shaped steel with the structure has simple structure and can lower the production cost of rims.
Description
Technical field
The utility model relates to a kind of engineering truck wheel rim shaped steel.
Background technology
The wheel rim that engineering truck is used all is to form by the flow forming of rim rolling machine to wheel rim shaped steel.Its section form more complicated of existing wheel rim shaped steel, especially its with the portion's section that cooperates of tire on arc groove and convexity more, the roll complex structure of rolling wheel rim shaped steel and the rim rolling machine complex structure of processing wheel rim have been brought thus, increase the rolling difficulty of wheel rim shaped steel and the moulding difficulty of wheel rim, caused the productive costs of wheel rim to strengthen.
The utility model content
The technical problems to be solved in the utility model is at above-mentioned deficiency, and the engineering truck wheel rim shaped steel that a kind of section form is simple, can reduce the wheel rim productive costs is provided.
In order to solve the problems of the technologies described above, the utility model provides a kind of engineering truck of following structure wheel rim shaped steel, the cross-sectional plane of shaped steel has a flat segments that matches with tire, one end of flat segments upwards vertically outwards is bent into an arcuation limiting leg after the bending again, and the kink that connects limiting leg and flat segments is an overstriking section that seamlessly transits; The other end of flat segments upwards bends inwards after the bending of oblique below again and forms the crotch section of an overstriking, and the inside face of crotch section surrounds the press strip groove.
The wheel rim shaped steel of said structure because its section form is simple, especially with flat segments that tire cooperates on without any arc groove and projection, therefore, can make rolling roll of the present utility model simple in structure, also can make rim rolling machine simple in structure, indirect reduction the productive costs of wheel rim; Still because its section form is simple, make the rolling difficulty of shaped steel and all be reduced with the moulding difficulty that shaped steel is rolled into wheel rim, shortened the production cycle, reduced consumption, reduced the productive costs of wheel rim indirectly or directly.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Accompanying drawing is a cross-sectional structure scheme drawing of the present utility model.
The specific embodiment
Engineering truck wheel rim shaped steel as shown in drawings, its cross-sectional plane has a flat segments that matches with tire 1, one end of flat segments 1 upwards vertically outwards is bent into an arcuation limiting leg 2 after the bending again, and the kink that connects limiting leg 2 and flat segments 1 is an overstriking section that seamlessly transits 3; The other end of flat segments 1 upwards bends inwards after the bending of oblique below again and forms the crotch section 4 of an overstriking, and the inside face of crotch section 4 surrounds press strip groove 5.The crotch section 4 of overstriking section 3 and overstriking can increase the load-carrying capacity of wheel rim.
Claims (1)
