Description
Technical field
The present invention relates to the manufacturing process of packaging container of metal, specifically a kind of improvement to its drying plant and processing technology.
Background technology
Support in the drying plant is commonly called as " Pattern iron supporter ".When making the packaging container of metal of products such as food, medicine, chemical industry, usually all need print some exquisite patterns at the metal sheet surface that the manufacturing container is used, and then metallic plate placed the drying room inner drying, Pattern iron supporter is exactly the support that is used for the support metal plate that is installed in the drying room.At present, the printing equipment of China mainly relies on external import, and the drying plant supporting with it is mainly by domestic manufacturing.Usually, a cover drying plant approximately need be used the Pattern iron supporter about 3500.In the prior art, the technology that this Pattern iron supporter usually adopts the outer surface at two bonding jumpers to carry out inferior arc welding is made, therefore produce weld defect in bar surface easily, cause the metallic plate of making container in the oven dry running, the burr that is produced because of welding on the Pattern iron supporter scratches, and badly influences the surface quality of packaging container of metal.
Summary of the invention
The objective of the invention is to seek the manufacture method of the support in a kind of drying plant,, improve the surface quality of canister to avoid scratching and scalding the surface of metallic plate because of support.
According to design provided by the present invention, drying plant comprises a, raw material preparation with the manufacture method of support: the length that bonding jumper is broken into requirement; B, welding: two bonding jumpers are welded together; C, plating utilize conventional electroplating technology, at the good bar surface coated coating of welding; It is characterized in that: before the bonding jumper welding, on bonding jumper, process earlier the salient point of welding usefulness, again two bonding jumpers are placed anchor clamps, salient point and another a root bonding jumper on the bonding jumper is adjacent to, carry out the butt-joint welding then; Ceramic rollers is installed after plating, when assembling, earlier bearing pin is installed on the side of bonding jumper, again ceramic rollers is connected on the bearing pin.
When butt-joint is welded, earlier bonding jumper is applied the first pressure pressure of 5500～6000N, 0.5 after～1.5 seconds to electrifying electrodes, electric current is 22000～24000A, time is 0.14～0.16 second, and the salient point 5 on the bonding jumper 1 is fused fully with another bonding jumper, again through 1～2 second electrode pressurize, with the typing solder joint, two bonding jumpers are welded together fully.
Advantage of the present invention is: owing on support, be provided with ceramic rollers, thereby avoided the problem of support scuffing and scald metallic plate, and improved the presentation quality of packaging container of metal; Ceramic rollers is smooth hard, has both prolonged the service life of Pattern iron supporter, can guarantee metallic plate smoothness, steady when the input Pattern iron supporter again.On bonding jumper, process earlier when carrying out butt-joint again behind the salient point, can effectively improve the weld strength between bonding jumper, and avoid forming weld defect, thereby stop the damage of bonding jumper metallic plate in bar surface.

The specific embodiment
As shown in Figure 1: the side at the bonding jumper 1 of forming this support connects some bearing pins 2 uniformly, connects ceramic rollers 4 again on every bearing pin 2 respectively.Connect again in the outer end of bearing pin 2 and to be used to limit ceramic rollers 4 axially movable securing members 3, in case ceramic rollers 4 comes off.The outer rim of ceramic rollers 4 should be greater than the width of bonding jumper 1, to guarantee that metallic plate rests on the ceramic rollers 4 when mobile, do not contact with bonding jumper 1, avoid bonding jumper 1 damage metallic plate, simultaneously, the heat conductivility of ceramic rollers 4 is relatively poor, therefore the high temperature on the bonding jumper 1 can not passed to metallic plate, thereby has stopped the possibility of Yin Gaowen scald metallic plate.
The manufacture method of this support comprises a, raw material preparation: the length that bonding jumper 1 is broken into according to a conventional method requirement;
B, welding: on bonding jumper 1, process earlier the salient point 5 of welding usefulness, again two bonding jumpers are placed anchor clamps, a salient point 5 on the bonding jumper 1 and the plane of another root bonding jumper 1 are adjacent to, and place among two electrodes of electric welding machine, carry out the butt-joint welding then; During welding, earlier bonding jumper is applied the first pressure pressure of 5500N, after 1.5 seconds to electrifying electrodes, electric current is 24000A, and the time is 0.16 second, and the salient point 5 on the bonding jumper 1 is fused fully with another bonding jumper, through 2 seconds electrode pressurize,, two bonding jumpers are welded together fully again with the typing solder joint;
The characteristics of this welding procedure are: 1, the tensile strength height of pad; 2, when 230 ℃ of bakings, its intensity is higher than the intensity of original product; 3, when electroplating, can accomplish 100% face plating, when adopting inferior arc-welding originally, there is not coating at inwall, in use, influence the service life of Pattern iron supporter easily by the corrosion of waste gas such as benzene, acid, sulphur; 4, welding deformation is little, and when adopting inferior arc-welding originally, welding deformation is bigger, causes whole Pattern iron supporter distortion easily; 5, do not have the welding scar, can not damage the surface smoothness of Pattern iron supporter, when former inferior arc-welding was welded, the welding scar of generation can damage the surface smoothness of colored armor; 6, solved the most difficult problem in tin graphed sheet, the coating material production---the scratch of metal sheet surface.
C, plating utilize conventional electroplating technology, at the good bonding jumper 1 surperficial coated coating of welding;
D, ceramic rollers 4 is installed after plating, when assembling, earlier bearing pin 2 is installed on the side of bonding jumper 1, again ceramic rollers 4 is connected on the bearing pin 2, and utilizes jump ring 3 location.The characteristics of ceramic rollers are: 1 smooth hard roller surface has guaranteed that metallic plate is steadily smooth when the input Pattern iron supporter; 2, the corrosion of ceramic rollers waste gas such as anti-benzene, acid, sulphur in drying course; 3, ceramic rollers paint having no volatile substances has reduced the airborne pollution of oven dry; 4, the ceramic rollers of high temperature sintering moulding has excellent heat insulation property, has guaranteed that metallic plate avoids the scald of Pattern iron supporter.
