Hardware packs products technology brief analyse

Metal bear imprint processing technology should be passed individually after content imprints, in goods shape the cent in craft:
1, punch craft. Metal packaging container, no matter be box or canister, from shape look on craft, it is to apply metallic punch principle mostly, do not be out of shape with plasticity through fire two big working procedure and shape.
Part working procedure is to make stamping workpiece and the contour line that place of board makings edge requests part each other, the punch that acquires certain section quality machines a method. Respectively working procedure often is included cut off, fall the operation such as makings, punching, cut, long edge and analyse edge.

Plasticity is out of shape working procedure is to make punch semifinished product allots model deformation sex in the condition that does not damage, machine a method in order to obtain the punch of the appearance of a request and dimension precision. Have labyrinthian, drawing, take shape normally 3 kinds. Include zigzag pressure curved, curly, ill-natured, fold a turn, boil pressure, it is music turn, important to pull a turn to wait for operation; drawing it is to pull mix greatly attenuate help method of deep; figuration more, include reverse opening of aperture, flange, enlarge, shrink mouth, figuration, roll edge, bulging, come back pressure, reciprocity of plastic, school is operated.

2, the craft that make jar. The traditional production method of the metallic canister that pack is: Cut preform of iron sheet flat into parts first grow diamonds, after that base
Cylinder of makings roll into (namely cylindrical shell) the solder of stannum of fore-and-aft joint line that creates place again rises, cause side say sth definitive so as to prevent further discussion, a termination of cylinder (namely coal tub bottom) with the circle upright lid uses machinery to the method causes flange and boil press heal (this namely double an edge juncture) , cause other one aspect of the matter of can body; to zip again after loading a product thereby cover. Because container is by coal tub bottom, can body, cover 3 local composition, friend says 3 canister. This kind of method that make jar 150 come for years, basically do not have how old change, just change the respect such as level and treatment precision actively to progress greatly, in recent years the fusion welding of welding line instead side heal.

70 time Chu Chong showed a kind of new principle that make jar. Comply with this one principle, can body and coal tub bottom are a whole, become by the flat base punch of a circle, load the heal after the product, this namely 2 canister. This kind of canister has two kinds to shape method: Punch -- attenuate drawing law (rush namely unplug law) with punch -- again punch law (develop law) greatly namely. These skill oneself are not new. Strong unplug the law is early in the the First World War already used at making cartridge case, making what coal tub differs to it is the rate that uses ultrathin metal and consumption tall (produce per year a quantity to be able to amount to several) .

The production of 3 canister produces course is: With cut machine general to coil material cuts lacquer of; of unripe rectangle plank and outfit to act presswork; cuts cylinder of roll into of; of unripe strip preform solder side seams; to repair commissural with cylindrical shell of coating; cut; causes groove or moire; is in; of flange of two upright extrude boils.

The treatment working procedure of cylindrical shell is curly figuration and solder side are seamed. Side seams add up to a method to basically be stannic solder law.

The stannic solder of stannic solder canister is comprised by the lead of 98% and the stannum of 2% individually. The cylindrical shell cylinder of flat base roll into production machine is with what undertake stannic solder side is seamed close machine is didymous apply. Inside cylindrical shell production machine, the edge classics of board base is cleaned and the turn becomes hook entity, facilitate when causing cylinder so fixed. After that cylindrical shell passes side sealing machine, add solvent and solder, with area of heal of warm-up of gas spray gun, pass gyro wheel of fore-and-aft stannum solder, heat further make solder sheds full juncture, use later rotate it is important to blow roller the superfluous solder that exists with drop record eliminates cleanness.
