Description
Technical field
Special-purpose hanger when the present invention relates to a kind of steel wheel electrophoretic painting
Background technology
In recent years, reduce cost along with the increase of automobile market demand and automobile vendor subtract to join, replacing the aluminium wheel with steel wheel has become the first-selection that many enterprises reduce cost.Last procedure of steel wheel production is an electrophoretic painting.Practice shows, in the electrophoretic painting process, hanger whether manufacture and design the advanced person, directly influence steel wheel product appearance quality, production efficiency and manufacturing cost, have crucial effects.In the prior art, the hanger that manufactures and designs the steel wheel electrophoretic painting nearly all is to adopt following two kinds of general modes:
1. clamping stagnation wheel rim type application hanger
This hanger has U-shaped rake fork by one one end and is positioned at that the L shape crotch of epimere portion forms.The weak point of this clamping stagnation wheel rim shaped steel wheel application hanger is:
(1) lifting workpiece difficulty.Artificial when going up the application workpiece, must the right-hand man work simultaneously, set upright hanger on the other hand, portable an application workpiece also goes at a slant to cater to and aligns hook, could finish the last part installation work of application steel wheel extremely difficultly.During following application workpiece, need equally workpiece just can be taken off at a slant, relatively waste time and energy.
(2) easily cause hydrops and the pocket water that influences quality product, waste starting material: owing to position of centre of gravity and application steel wheel product structure reason, be suspended on the stagnate steel wheel of position of U-shaped rake fork, the easy low side position hydrops of side body annular groove in steel wheel forms " pit " of a pocket water.Though its subsequent handling takes certain measure to remove pocket water, can't eliminate fully all the time, cause in the end forming some in the high bake and have a strong impact on the buildup of visual appearance.In addition, according to common electrophoretic painting production critical workflow: operations such as pre-degreasing, degreasing, ultrasonic wave pickling, neutralization, table accent, phosphatization, electrophoresis, each workpiece per pass operation all will be taken away the part tank liquor when production run, take tank liquor out of and cause tank liquor loss owing to wheel, slattern a large amount of starting material.
(3) supplementary product onsumption is bigger.When entering tank liquor, because the air at steel wheel housing annular groove outside place can't get rid of totally, phosphatize phosphate coat and electrodeposited paint film can't be attached to last and produce foaming, " paint face " phenomenon.Therefore when rolling off the production line, also to carry out touch-up paint to each steel wheel workpiece herein.In addition will be at the hanger contact position on the workpiece appearance surfaces, promptly the point of contact of each hook (totally 3) carries out touch-up paint, and the paint expense that artificial touch-up paint expense and touch-up paint are consumed is higher.
2. hang center pass hanger.This hanger is with a hanger perpendicular to the composition of the bar anyhow in the vertical rod.The centre hole of steel wheel is by above-mentioned bar anyhow, and steel wheel is suspended on anyhow on the bar.The weak point that this hanger exists is:
(1) paint spraying inconvenience.The steel wheel workpiece will be in each spray section in operational process, is subjected to the strong flushing of spray water and rotates and swing, and causes each location of workpiece fixing, after it need being set upright again when spraying paint, can spray paint.So not only inconvenient operation, and visual appearance is also unstable.
(2) auxiliary elapsed time is longer.Since not of uniform size the causing of steel wheel product of every kind of specification, central shaft location point of contact disunity.Guarantee good electrical conductivity, the electrodeposited paint film at the last contacted central shaft locating point of a product place must be removed during last part.Therefore, the workman must rotate workpiece at every turn when reaching the standard grade, and to gall the electrodeposited paint film of hanger point of contact, has increased unnecessary non-cutting time without rhyme or reason.
(3) supplementary product onsumption is bigger.Because the hanger contact position is on the hole wall of the center of workpiece, contact surface is big and long, the artificial touch-up paint that must waste time and energy at the point of contact of hanger.Paint cost and cost of labor that touch-up paint consumed are higher, and during finishing operation transient equilibrium detection, need locate with centre hole before workpiece packing, and touch-up paint not dried in the centre hole will have a strong impact on visual appearance.
Summary of the invention
The objective of the invention is weak point at above-mentioned general hanger existence, propose that a kind of location is reliable, lifting workpiece convenient, can reduce supplementary costs, can avoid steel wheel workpiece hydrops pocket water and artificial touch-up paint again, can also avoid hanger to clean and move back the hanger of lacquer processing.
Above-mentioned purpose of the present invention can reach by following measure: a kind of steel wheel electrophoretic painting hanger, comprise, a main backstay (1) and a cantilever backstay (2), and at least two hooks that hang steel wheel, it is characterized in that, described hook connects firmly a little by connecting firmly same, can be by the steel wheel wind hole of dispelling the heat, acclivitous cantilever backstay (2) and V-arrangement intersection galianconism backstay (3) are formed, be shaped on a needle point on contact workpiece surface on galianconism backstay (3) free end, cantilever backstay (2) is directly controlled the part rotary freedom.
The present invention has following beneficial effect than prior art.
The utility model hanger not only ensure the quality of products but also can reduce supplementary costs, and solved following problem:
1, the lifting workpiece difficulty, locate insecure problem
Because each steel wheel all has heat radiation wind hole, adopts this hole load-bearing and location, handled easily; By two angled galianconism backstays, to add the cantilever backstay and directly control the part rotary freedom, the location is reliable, makes things convenient for lifting workpiece again, does not need to tilt certain angle with regard to wheel about the energy.
2, hanger cleans and moves back the problem of lacquer
Practice shows, as long as there is the point of contact of " needle point " size just can satisfy the requirement of conduction between workpiece and the hook.Through improving the hanger of design, the hook part adopts the reinforcing bar manufacturing, and the shape of hook is determined according to the product type comprehensive selection, and adopted 2 contacts, by workpiece deadweight, will scratch with the electrophoretic paint layer of the contacted workpiece surface in hook tip and play the effect of conduction.Each use all is to adopt in such a way, just can avoid the cleaning of hanger and move back the lacquer processing, guarantees that workpiece fully conducts electricity, and has reduced cost, has improved production efficiency, has solved and has moved back the problem of environmental pollution that lacquer causes.
3, the problem of workpiece pocket water, hydrops
Reasonably design can solve quality problems such as part pocket water, workpiece lumen foaming fully, does not even need the pressurized air after electrophoresis is washed to blow water, effectively save energy (comprising electricity, gas etc.).
By practical proof that the present parameter of all product structures is carried out with grope, taken all factors into consideration and to have satisfied all product orientation, adopt main backstay (1) to become 78 ° with cantilever backstay (2), and the pitch angle of galianconism backstay (3) two arms and horizontal plane is 60 ° a structure, has solved pocket water, hydrops problem.
Find by field practice test: the part that this novel hanger mounts is not taken tank liquor substantially out of, changes next procedure over to after directly can water clock clean.Solved workpiece pocket water problems like this, all beneficial to the per pass washing step, quality both can be guaranteed, and can reduce again and pollute and rinse water replacing additional amount, and the use of conserve water has reached cleaner production, energy saving purposes.
4, the problem of artificial touch-up paint
Since adopt the louvre location during hanger design, very little to the wheel appearance effects herein, as a contact, do not need artificial secondary touch-up paint; In addition, through facts have proved, because galianconism backstay two knee-joint contacts are needle point, its point of contact is very little when locating with workpiece, after taking off workpiece, this point of contact inner chamber does not have yet presses the bubble grinning effect, almost touch-up paint not, the paint expense that artificial touch-up paint expense and touch-up paint are consumed be can save fully, artificial japanning and touch-up paint cost saved.
