Comprising the following steps of the present embodiment:
(1) surface treatment
To get rusty a little with acetone or absolute ethyl alcohol and abraded area cleans up rear polishing, by getting rusty a little of having polished with scuffing face cleans up with acetone again; During polishing, position, crowded traumatic part and getting rusty is exceeded the part polishing of datum level a little to datum level, and by the greasy dirt that scratches or get rusty in a groove and foreign substance cleaning totally, then with rotary file by whole scuffing face or a hacking that gets rusty.Repair wearing and tearing or protruding part of getting rusty, and then repair, hacking be convenient to scuffing face or rust spot in subsequent process with the combining closely of wlding.
(2) weld
Be welded on electric welding and get rusty a little and on scuffing face, under normal temperature, welding current is 200A, and wlding is 502 welding rods;
(3) sanding and polishing
To jack 1 sanding and polishing after welding, the solder joint on surface is tied; Chromium plating is carried out again after jack 1 after sanding and polishing is clean with acetone or washes of absolute alcohol.
(4) electroplate
Jack 1 after sanding and polishing is electroplated, makes layers of chrome on its plated surface.
As shown in Figure 1, jack 1 polissoir of the present embodiment comprises lathe 109 and the motor 101 be separately positioned on lathe 109, fixture, hydraulic jack 102, fixed mount 103, polishing disk 104 and dust shield 105, described fixture comprises chuck 107 and top 108, chuck 107 and top 108 lays respectively at the two ends of lathe 109, chuck 107 is connected with motor 101, one end of top 108 is for clamping jack 1, the other end is set on fixed mount 103, fixed mount 103 is fixed on lathe 109, polishing disk 104 is connected with the hydraulic stem of hydraulic jack 102, polishing disk 104 is positioned at the opening of dust shield 105, the bottom of dust shield 105 is provided with two extraction fans 106.
During polishing, motor 101 drives chuck 107 thus drives jack 1 to rotate, and the flexible drive polishing disk 104 of hydraulic jack 102 carries out polishing along the axis direction of jack 1.A large amount of dusts and particle can be produced in polishing process, if dust or particle enter the surface of jack 1 again, secondary pollution can be caused, thus the surface quality of jack 1 can be affected, extraction fan 106 coordinates dust shield 105, the dust of dishing out and particle can be siphoned away, thus reduce the Quality Down problem that secondary pollution causes.
As shown in Figures 2 and 3, jack 1 electroplanting device of the present embodiment comprises electroplating pool 111, machine thick stick 112, cooling body 113, the inwall of described electroplating pool 111 is provided with multiple heat-generating pipe 114, along the surrounding of electroplating pool 111 and mid-mounting, electrode 115 is set, the two ends of machine thick stick 112 are overlapped on electroplating pool 111, jack 1 is suspended on machine thick stick 112 by suspender 120, cooling body 113 is arranged at the two ends of machine thick stick 112 respectively, the two ends of machine thick stick 112 are fixedly installed the heat transfer block 116 that cross section is V-type, the cooling block 117 of described cooling body 113 to be hollow cross section be M type, described heat transfer block 116 is arranged at the top depression place of cooling block 117, the bottom of cooling block 117 is fixed on the edge of electroplating pool 111.
Machine thick stick 112 is in electroplating process, and due to the electroplate liquid in heat-generating pipe 114 constantly heating electroplating pool 111, jack 1 is heated, conduct to machine thick stick 112, electroplating time is slightly long, machine thick stick 112 will be caused due to overheated and deform, thus cause machine thick stick 112 life-span to be die-offed.The inwall of what heat-generating pipe 114 was parallel to each other be arranged on electroplating pool 111, can improve heating efficiency.Cooling block 117 is offered water inlet 118 and delivery port 119, water inlet 118 is positioned under delivery port 119.The bottom water inlet of cooling block 117, top water outlet, can effectively reduce the temperature of M type structure recess.Meanwhile, machine thick stick 112 is hollow structure, coordinates the heat transfer block 116 at two ends, can reduce temperature rapidly, improves the service life of machine thick stick 112.
As shown in Figure 4, the present embodiment comprises integrated suspender body 121, clamping dish 122 and clamping part 123 for the suspender 120 hanging jack 1, clamping dish 122 is arranged at the bottom of suspender body 121, described clamping dish 122 is offered multiple connecting screw hole 124 for connecting jack 1, clamping part 123 is arranged at the top of suspender body 121, Open Side Down for clamping part 123, and shape and the machine thick stick 112 of opening match.Open Side Down for clamping part 123, can ensure effectively can clamp in the process of clamping and can not come off.
The bottom of suspender body 121 and the angle of assembling dish 122 are 70 ~ 85 °; suspender body 121 is connected design with the non-perpendicular of clamping dish 122; 1 one, the jack power obliquely of lifting can be given; because the weight of jack 1 is larger; active force obliquely; the component of a horizontal direction can be produced, reduce and be applied to pulling force vertical on clamping part 123, clamping part 123 and whole suspender 120 can be protected to a certain extent to have the longer life-span.
The top of clamping part 123 is provided with hanger 125, is provided with through hole in hanger 125.Time no, suspender 120 entirety can be hung up.When jack for moving 1, suspender 120 is fixedly linked by the screw on bolt and jack 1, one end of lifting rope or suspension rod is connected in crane or driving, the clamping part 123 of the other end and suspender 120 with the use of, to be on the safe side, lifting rope can also be worn on hanger 125, prevent suspender 120 from coming off, play the effect of double insurance.
