Abstract
The invention relates to the field of automobile part and component manufacturing technologies, in particular to an automobile wheel fender and a cold stamping forming technology of the automobile wheel fender. The wheel fender at least comprises a wheel fender body and reinforcement ribs located on the inner wall of the wheel fender body. The wheel fender body comprises a wheel fender upper portion and a wheel fender lower portion, multiple curve-shaped edges are arranged on the wheel fender body and comprise the edges matched with a front pillar of the side wall of an automobile body, the edges matched with an A pillar of the automobile body, the edges matched with an engine cover and the edges matched with a front bumper. Positioning installation holes are further formed in the wheel fender lower portion and the edges matched with front combination lamps. A special-shaped hole is further formed in the wheel fender body. The automobile wheel fender formed in a cold stamping mode is not prone to cracking in the use process, small in influence caused by outside temperature, long in service life, simple in technology and low in cost.
Description
Technical field
The present invention relates to Manufacturing Technology for Automotive Parts field, particularly relate to a kind of fender and process for cold stamping shaping thereof.
Background technology
Fender guard is to hide the vehicle-body outer panel of wheel, because of this component shape of old-fashioned vehicle body and position, like pinion, gains the name, and fender guard is installed rigging position and is divided into again wing and boot-mounted wing, and wing is arranged on front-wheel place, and boot-mounted wing is arranged on trailing wheel place.
Fender guard body of the prior art is the integral structure of integrated injection molding, although the distortion under the impact of certain load of the fender guard of engineering plastic structure is little, but be subject to external environment impact such as when winter, or be subject under external impacts effect, the fender guard of plastic construction is more crisp, the stressed a little cracking that is easy to.
Summary of the invention
The shortcoming of prior art in view of the above, the object of the present invention is to provide a kind of fender and process for cold stamping shaping thereof, for solving the problem that easily cracks under the external impacts load that the integral structure fender guard of prior art integrated injection molding produces.
For achieving the above object, the invention provides a kind of fender, described fender guard at least comprises: fender guard body and the reinforced rib that is positioned at described fender guard inner body wall, described fender guard body comprises fender guard top and fender guard bottom, described fender guard body is provided with some curvilinear edges, described edge is respectively the edge coordinating with body side wall front pillar, the edge coordinating with vehicle body A post, the edge coordinating with engine case, and the edge coordinating with front bumper, described fender guard bottom and be also provided with location and installation hole with the part of front combination lamp matched edges, on described fender guard body, be also provided with profiled holes.
The present invention also provides a kind of fender process for cold stamping shaping, comprises following processing step:
Blanking: be about to whole plate shears and be cut into single billot;
Blanking: be about to billot and carry out stamping-out with location, limit;
Drawing: be about to blank and locate by locating dowel pin with limit, upper and lower mould is adjusted to the right place, suppresses;
Deburring and punching: the workpiece that is about to drawing acquisition carries out deburring and rushes profiled holes with interior shape location;
Flange, side blow and side shaping: the workpiece that is about to obtain after punching is located with interior shape, carry out flange and rush location and installation hole, and carrying out side shaping;
Through above-mentioned technique, make described fender.
As mentioned above, fender of the present invention and process for cold stamping shaping thereof, have following beneficial effect: adopt cold stamping shaped a kind of fender, be difficult for forming crackle in use, affected by ambient temperature little, long service life; And cold stamping shaped fender guard technique is simple, cost is low.
