Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is explained further details.
The present invention relates to a kind of method for processing plating layer of inner wall of oil tank, at first with the fuel tank integral solder, the inwall of fuel tank is carried out the barrel plating of zn alloy coating again, wherein the barrel plating step of zn alloy coating is carried out in turning device.After the FCL welding step; At first inner wall of oil tank is carried out surface treatment; Adopt the chemical pickling method to remove impurity such as the oxide debris on fuel tank internal surface, iron rust, pickling washed twice with cleaning water to inside after 10～15 minutes, carried out the barrel plating step of following zn alloy coating again:
A, in casing, add impact media (granulated glass sphere) and water, the water yield accounts for 1/4～1/3 of box height;
B, with the intravital pH value to 1 of plating bath adjustment agent adjusting tank～2, employed plating bath adjustment agent is the vitriol oil (massfraction is 98.3%) in present method;
C, add zinc powder (400 order) back upset 2～5 minutes, be 3 minutes best flip-flop transition;
Overturn 2～8 minutes after d, the adding promotor, be 5 minutes best flip-flop transition, and employed promotor is PS agent, i.e. PS in present method;
E, aforementioned c, d steps in sequence are circulated to desirable thickness of coating, and needing to use plating bath adjustment agent to keep the intravital pH value of case in the process is 1～2;
Overturn 1～3 minute behind f, the adding brightening agent;
Add the water upset in g, the casing, the time generally is that the longer the better, can thoroughly remove reactant residual in the casing, again with the casing emptying.
The method that zinc coating is rolled in first FCL welding again more than the employing; Overcome in the traditional method the zinc-plated assembling again of inner wall of oil tank elder generation veneer welding; Avoid the destruction of butt welded seam part zn alloy coating in the welding process, strengthened the preservative property and the solidity to corrosion of inner wall of oil tank, prolonged the work-ing life of fuel tank.
Another program of the present invention provide a kind of in the inner wall of oil tank coating course of processing the employed device that can realize the upset of fuel tank 360 degree; Comprise supporting seat and motor; Wherein supporting seat is made up of base 1 and the wing seat 2 that is located at base 1 both sides; A resupination framework 3 passes through the transmission mechanism 5 that horizontal bearing connects vertical direction 360 degree circumferential motion in the wing seat 2, and the transmission mechanism here is an external toothing straight tooth gear mechanism.Be connected to resupination framework 3 in the steady bearing 7 that other has the transmission mechanism 6 of a rotating mechanism 4 through horizontal direction 360 degree circumferential motion and rotating mechanism 4 to divide into, the transmission mechanism here is a pinion and rack, and wherein section of rack is horizontal.
The external toothing straight tooth gear mechanism 5 that carries out movement in vertical direction is connected with a braking motor 8, and 8 these external toothing straight tooth gear mechanisms 5 of control carry out the uniform rotation of vertical direction by braking motor.And the pinion and rack 6 that carries out horizontal motion is connected with a buncher 9, by buncher 9 these pinion and racks 6 of control, according to the size of fuel tank and the needs adjustment velocity of rotation of feeding quantity.
A holddown 10 is established in the upper end of resupination framework 3, and major parts is a compressor arm 11, and an end axle of compressor arm 11 is connected on the resupination framework 3, and the other end passes through snap fit on resupination framework 3.The push bolt 14 that compressor arm 11 is provided with 12, one lower ends connections of opening pad 13 is connected with compressor arm 11 through opening 12.When inserting reservoir port in the rotating mechanism 4 up, the corresponding setting of opening 12 with reservoir port, and the size of pad 13 is greater than the reservoir port size.
In order to ensure rotating mechanism 4 in resupination framework 3, horizontally rotate at the uniform velocity and smooth; Can establish pulley at the inner ring of resupination framework 3 horizontal components; Be used for maintenance on the one hand to rotating mechanism 4; Can reduce the friction that contacts of rotating mechanism 4 and resupination framework 3 on the other hand, realize rotating mechanism 4 at the uniform velocity, 360 smooth degree horizontally rotate.
The workflow of this turning device is: reservoir port is put into rotating mechanism 4 up, buckle holddown 10, this moment, pad 13 just placed the reservoir port top, and behind the push bolt 14 of screwing, fuel tank is fixed in the rotating mechanism 4.Opening device, external toothing straight tooth gear mechanism 5 is under the effect of braking motor 8, and the rotating mechanism 4 that connects in drive resupination framework 3 reaches is done the at the uniform velocity upset of vertical direction 360 degree together.Simultaneously, pinion and rack 6 is under the effect of buncher 9, and the rotation of horizontal direction 360 degree is done by driven rotary mechanism 4, and the rotating speed of adjusting rotation at any time according to the size and the feeding quantity of fuel tank.At this moment, fuel tank can carry out 360 turn flip-flop movement in whole device, according to preceding method the barrel plating material is added in the fuel tank successively, and the impact media of utilization inside to cabinet wall, makes inner wall surface form uniform zn alloy coating the coating impact.
