Embodiment Construction
[0029] In order to make the purpose, technical solution and advantages of the technical solution of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of specific embodiments of the present invention.
[0030] Please see attached figure 1 And attached figure 2 , a rectangular steel coil forming process suitable for spoke hubs, said process comprising the following steps:
[0031] Step1, blanking: cutting the raw material into a flat blank 1;
[0032] Step2, rolling: use a rolling machine to roll and deform the flat blank 1 of the specified size to make a cylindrical part a2;
[0033] Step3, butt welding: use the butt welding machine to perform flash butt welding on the butt joint of the rounded cylindrical part 2, and use the slag planer, rolling machine, end cutting machine, etc. to process the weld generated during welding, Remove welding slag t...

The invention discloses a rectangular steel plate coiling-spinning forming process suitable for spokes and hubs. The rectangular steel plate coiling-spinning forming process suitable for the spokes and hubs has a flow comprising the steps of firstly cutting a raw material into a slab blank; then carrying out rolling, butt-welding and welding seam treatment on the slab blank so as to form a cylindrical workpiece with a certain wall thickness; grooving and horn-flaring the cylindrical workpiece so as to form a preliminary formed part; then spinning to form a spoke, a hub or a brake drum shell and other products; and finally locally turning to form a final product. Except for the final local turning process, no hollow wastes and leftover materials can be produced during the steel plate coiling-spinning process flow, so that compared with a traditional process, the rectangular steel plate coiling-spinning forming process suitable for the spokes and hubs is more cost-efficient and material-saving.
Description
technical field [0001] The invention relates to a process flow for processing wheel components, in particular to a rectangular steel plate coil forming process suitable for spoke hubs. Background technique [0002] For traditional steel wheels, the wheel is generally composed of two parts: the spoke and the hub. The spoke and the hub are respectively formed through a series of processes, and finally the two are welded to form the wheel. Among them, the technological process of the spokes is as follows: the circular steel cake with a certain diameter punched by a hydraulic press is used as the raw material, and after the middle hole and the bolt hole are punched by the hydraulic press, a dimple with a certain contour shape is formed by strong spinning The shape or bowl is the spokes. During this process, the punching of the two hydraulic presses produces leftovers and mesopore wastes, which account for a large proportion of the overall raw materials. [0003] The process fl...
