Description
Technical field
The present invention relates in the wheel manufacturing manufacturing process of no-seam steel felly, particularly a kind of manufacturing process of steeliness wheel rim without welding line and with inner tube.
Background technology
The steel wheel that the inner tube of a tyre is arranged be use at present one of automotive wheel, particularly truck wheel the most widely.General steel wheel is to be made respectively by spoke and wheel rim two parts, welds together then.In existing several production method for wheel, on the manufacturing process of spoke, be more or less the same, and on the manufacturing process of wheel rim, differ greatly.The manufacturing process of wheel rim is concluded and is mainly contained following several process program:
1. shaped steel steel coil strip/welder plants.
2. dull and stereotyped steel coil strip/weldering/lathe turner's skill.
3. seamless steel pipe spinning process.
The wheel rim of process program 1 manufacturing is to process through blocking, enclose operations such as circle, welding and the circle that expands with the cross section rolled section steel steel band identical with the wheel rim cross section.Its advantage is: technical process is simple, and low cost of manufacture is the at present domestic process that generally adopts.Its shortcoming is: because weld seam is curved, welding slag is difficult to remove clean, and type quality is poor, and cold deformation is little, so intensity is low.The wheel rim of process program 2 manufacturings processes through blocking, enclose operations such as circle, welding, bloated circle and three road spinning with dull and stereotyped band steel.Its advantage is: because weld seam is rectilinear when removing welding slag, welding slag is removed clean, and type quality is good; Through the spinning cold deformation, intensity is higher.Its shortcoming is: because thickness of slab is thicker, enclose, be welded into high; The weld seam that a perforation is arranged on the wheel rim ftractures in the processing of cold deformations such as follow-up spinning easily; In use the weld seam on the wheel rim damages under frequent alternate stress effect easily.Process program 3 usefulness seamless steel pipes are made no-seam steel felly, and raw-material cost is very high, therefore up to the present, adopt this technology without any wheel manufacturer.
Summary of the invention
The present invention is intended to propose the method that the lower-cost raw material manufacturing of a kind of usefulness does not have the rim for automobile wheel of weld seam, a kind of manufacturing process of steeliness wheel rim without welding line and with inner tube.
The step of this manufacturing process of steeliness wheel rim without welding line and with inner tube comprises the blanking of strand steel pipe, heating, rolling expansion, smart rolling, full circle, spinning, draws spinning roller edge, Vehicle Processing two ends and valve hole.Wherein the blanking of strand steel pipe, heating and rolling are expanded 3 procedures and are cut into pipeline section for the principle that the strand steel pipe is by volume constant, are heated forging temperature then, roll over Ring Rolling Machine again and expand into intermediate blank, intermediate blank be shaped as wall pipe always.The described smart operation of rolling over becomes the first step at goods for Ring Rolling Machine one end of intermediate blank is rolled over out a gutter.Described full circle operation be with rounding machine with the first step at the goods full circle, make its circularity and internal diameter size reach the technological requirement of spinning machine.Described spinning operation is carried out spinning for the first step behind the full circle is enclosed within on the cylindrical spinning block at goods to its outer wall, makes the thickness at rim base and bcad seats place reach the dimensional requirement of finished product, becomes for second step at goods.Described draw spinning roller edge operation for second step in goods are placed on the spinning block of spill, an end of its no gutter is carried out spinning, draw the back-out wheel rim, become the 3rd and go on foot at goods.
Manufacturing process of steeliness wheel rim without welding line and with inner tube of the present invention can reduce cost owing to adopt the strand steel pipe as raw material; Roll over expansion processing with heat, it is to forge tissue that raw-material as-cast structure is made into; The processing of employing cold spinning not only can improve the machining accuracy of wheel rim, and can improve the strength of materials of wheel rim greatly by cold-working processing.Under the equality strength condition, can do wheel rim lighter by reducing wall thickness.The wheel rim of making is not owing to there is weld seam, and good product quality is safe and reliable.
