Description

Car panel die surface grinding glossing

Technical field

The present invention relates to automobile die manufacture field, and in particular to a kind of car panel die surface grinding buffer Skill.

Background technology

Auto industry is one of five big pillar industry of Chinese national economy, in order to meet the market requirement, automobile is remodeled the time Constantly shorten, 80% mould is there are about when automobile is remodeled to be needed to change, the automobile of a model, and required mould reaches thousands of pairs, one Vehicle averagely needs big-and-middle-sized cladding member mold about 260 secondary, is worth more than one hundred million members.The development that auto industry has been subjected to more than 100 years is gone through History, the perfect profile for making people increasingly pay close attention to vehicle body of performance, in recent years, each automobile manufacturing enterprise in the world is all by body contour Design and manufacturing capacity as the important symbol for weighing automobile particularly car model development level.Design, system in vehicle body In making, car panel die turns into important step therein because its technical difficulty is maximum, forming quality requires highest.

Because the mechanism of metal plastic forming processes is extremely complex, therefore mold design, manufacture are repaiied repeatedly based on experience Positive process.In Making mold, die trial and production maintenance stage, last procedure is the grinding and polishing of die surface, and this is Ensure the committed step of die surface quality, the speed that it directly affects the production cycle of mould, vehicle updates.And automobile The grinding and polishing quality of cladding member mold directly affects the plastic deformation and surface quality of stamping parts again, so as to influence market competition Power.

Existing mold grinding and polishing process is mainly carried out by hand, makes one of difficult point for influenceing production process. How to improve mould grinding and polishing technology, be pursuing a goal for Modern mould manufacture industry.

The content of the invention

It is simple that the technical problems to be solved by the invention are to provide a kind of technique, is significantly reduced error in geometrical form, work Imitate high car panel die surface grinding glossing.

In order to solve the above technical problems, a kind of car panel die surface grinding glossing of the present invention, including mould Corase grind, fine grinding and the polishing on surface；Corase grind, fine grinding and the polishing of the die surface are connect using surfaces of revolution contact or toward coverlay Touch；When the die surface is plane, contacted using surfaces of revolution contact or toward coverlay；Post, the conical surface 0 of the die surface<R< During 30mm, contacted using the surfaces of revolution, contacted toward coverlay, with flexible grinding stone, work as R>During 100mm, contacted using the surfaces of revolution, past coverlay Contact, with rigid grinding stone, works as 25mm<R<During 100mm, contacted using the surfaces of revolution, with flexible grinding stone；The sphere of the die surface 0<R<During 100mm, contacted using the surfaces of revolution, with flexible grinding stone, work as R>During 100mm, contacted using the surfaces of revolution, with rigid grinding stone； The Irregular Boundary Surface of the die surface is contacted using the surfaces of revolution, with flexible grinding stone.

Preferably, when the corase grind of the die surface, fine grinding and polishing require geometrical precision, carry out roughly grinding-essence Mill-polishing process；When corase grind, fine grinding and the polishing of the die surface do not require geometric accuracy, carry out refining-buffer Sequence.

The present invention is roughly ground, refined and polished with rigid grinding stone, and die surface quality is improved using face contact；Just Property grinding stone be ground polishing great advantage be reduce error in geometrical form.

Embodiment

The present invention is further illustrated below：

A kind of car panel die surface grinding glossing of the present invention, including the corase grind of die surface, fine grinding and polishing；Institute The corase grind, fine grinding and polishing for stating die surface are contacted using surfaces of revolution contact or toward coverlay；When the die surface is plane, Contacted using surfaces of revolution contact or toward coverlay；Post, the conical surface 0 of the die surface<R<During 30mm, contacted using the surfaces of revolution, be past Coverlay contacts, and with flexible grinding stone, works as R>During 100mm, contacted using the surfaces of revolution, contacted toward coverlay, with rigid grinding stone, work as 25mm<R <During 100mm, contacted using the surfaces of revolution, with flexible grinding stone；The sphere 0 of the die surface<R<During 100mm, connect using the surfaces of revolution Touch, with flexible grinding stone, work as R>During 100mm, contacted using the surfaces of revolution, with rigid grinding stone；The Irregular Boundary Surface of the die surface Contacted using the surfaces of revolution, with flexible grinding stone.

When corase grind, fine grinding and the polishing of the die surface require geometrical precision, roughly grind-refine-polish Process；When corase grind, fine grinding and the polishing of the die surface do not require geometric accuracy, carry out refining-polishing process.

In technique, corase grind makes die surface close to geometrical precision requirement；Fine grinding makes die surface reach geometric accuracy It is required that close to surface roughness requirements；Polishing is die surface is reached surface roughness requirements.

The size of mould configuration is different, and its engine request is also different, for plane, when its size is less than 100mm × 100mm And the radius of cylinder, cone, sphere, when being less than 100mm, the requirement of its geometrical precision is not considered.For Irregular Boundary Surface, one As both less than 100mm, be also not required to consider its geometrical precision.Conversely, it then must take into consideration geometrical precision.

The present invention further Optimizing Process Parameters, can significantly improve quality of finish, substantially reduce in prior art basis To the technical requirements of worker.
