Description

The sheet metal sanding apparatus
Technical field
The present invention relates to a kind of sanding apparatus, relate in particular to a kind of sanding apparatus that is applied to sheet metal.
Background technology
Laboratory and processing factory often use metal species sheet material; Before use need be to the plate surface processing of polishing; For example in adhesive tape industry, can use length in the time of the adhesion strength of needs detection adhesive tape is that 150mm, width are the corrosion resistant plate of 70mm, during detection; The article tape subsides that cut are paid at the good plate surface of polishing, place the adhesion strength of removing to draw adhesive tape behind the certain hour after the roll extrusion.In this process, if the plate surface polishing is rough, will cause the unusual of adhesion strength data, testing result is caused certain interference.
At present; Polishing for this type sheet material generally all is manual operation; Be specially: be used for fixing sheet material at fixing two thin plates of desktop, then sand paper be loaded on the abrasive sheet holder surface, so-called abrasive sheet holder is an armed thin plate in fact; There are anchor clamps can clamp sand paper above, then with its sheet material of polishing back and forth.The abrasive sheet holder of this type can referenced patent number be that (notification number: CN2095735U), this type polishing mode is relatively backward, has shortcomings such as working strength is big, efficient is low, polishing is of poor quality for the Chinese utility model patent " board-like sander " of ZL91206869.8.
Will add a certain amount of water at the plate face before the polishing, overheated the plate face affected to prevent to polish, the wiped clean afterwards of having polished is dipped in absorbent cotton more at last and is got organic solvent wiping is carried out on its surface, till the wiping light.Can be after blackboard eraser is wiped away in constant-temperature constant-humidity environment held a period of time, wait organic solvent to volatilize fully and the sheet material temperature and humidity just can be used during all with thermostatic constant wet chamber's term harmonization.Existing polishing mode, well cleaning environment.
During polishing in order to practice thrift sand paper, sand paper two boards material of often polishing, the sheet material of polishing earlier owing to be that new sand papering is effective, the sand paper effect of polishing effective not as good as polishing earlier often then.In addition, because manpower changes greatly, inhomogeneous often being difficult to of polish avoided, and particularly when a lot of piece sheet material of disposable polishing, the plate face of the big polishing of front strength is smooth often, and tired out strength at the back and died down, the smoothness reduction, polishing in front and back, often homogeneity is relatively poor.
As improvement; The patent No. is that (Granted publication number: CN2231360Y) disclosed a kind of like this Plate grinder, comprised support, the support upper bearing (metal) is connected with reverse-flighted screw for the Chinese utility model patent " Plate grinder " of ZL95214608.8; Being fixedly connected with parallel with reverse-flighted screw is the platen of material with steel or cast iron; Be connected to drive pin with reverse-flighted screw to the two-way nut of coupling, drive pin inserts and places in the sky on the planker on the platen, is inlaid with magnet on the planker; And being provided with the groove of adorning test plate (panel), reverse-flighted screw is connected with motor.The platen two ends also are provided with eccentric clamping device.At first sand paper is lain low on platen during work, rotate eccentric wheel, make sand paper clamped, test plate (panel) is placed in the groove on the planker, and place above the sand paper, in the circular hole of two-way nut on the drive pin insertion planker that connects.The magnet that is inlaid with owing on the planker can tightly be adsorbed on the platen, makes the enough normal pressures of generation between test plate (panel) and the sand paper.Work as electrical power, when driving the reverse-flighted screw rotation, stir plectane and move back and forth along platen through two-way nut, drive pin, test plate (panel) and sand paper joint receive even friction, reach smooth smooth purpose.This patent is polished through motor, greatly reduces labour intensity, has improved operating efficiency.
But there is following weak point in it: at first, the sheet material of once can only polishing, it is frequent to change sheet material and sand paper; For the bigger job requirement of sheet material quantity, seem unable to do what one wishes: secondly, the contact pressure of sheet material and sand paper provides by magnet; But because thickness has deviation a little between the different plates, and the distance between magnet and the platen is very big to the suction affects between on magnet and the platen, has so just caused thick plate and the thin suffered pressure of plate that very big difference is arranged; Be that the suffered pressure of thick plate is little, the pressure that thin plate receives is big, thereby causes thick plate polishing dynamics little; Thin plate polishing great efforts, thus the stability of final test data influenced; Once more, the magnet that inlay at two ends is difficult to guarantee the uniformity of magnetic, so just causes the stressed big end of an end stressed little, for plate face polishing effect very big influence is arranged; At last, its work top and plate face clean and have certain difficulty, clean totally not tend to follow-up personnel operation or whole nog plate device are affected, and have increased labor intensity of operating personnel because of cleaning simultaneously.
Summary of the invention
Technical problem to be solved by this invention is to the above-mentioned state of the art a kind of labour intensity that can reduce to be provided, high efficiency, the good sheet metal sanding apparatus of polishing quality.
