Steel Barrel Making Machine and Barrel Clip Production

Basic requirements: master the general structural features of steel drums and pails , use of materials and workmanship
Teaching content: 1, steel drum structure ; 2 , steel drum manufacturing process ; 3 , drums quality testing
Important and difficult: steel drum manufacturing process
Hours Distribution : 2 hours

7.1 Structural steel drums
Drums generally refers to the use of a metal plate made ​​of more than 0.5mm in size (greater than 20L) container. In accordance with the barrel material can be divided into steel drums , aluminum barrels, stainless steel barrels .

1, all open drums
Full opening drums opening equal to the inner diameter of the barrel body .


2 , closed steel drums
Barrel top and bottom of the barrel and the barrel is sealed by crimping combined into one body , and not removable .
( A ) prescribe ring bars ;
( 2 ) 3 ~ 7 ends corrugated ;
( 3 ) prescribe ring bars , ring bars to the bottom of the barrel between the top barrels have 3 ~ 7 ripples ;
( 4 ) There are three ring bars .
3 , steel pails


( 1) Steel structure type pails
① ear tight lid pails full opening
② full open pail lid seals
③ closed necking pails
④ closed pails

(2) T -type barrel structure size

(3) s -shaped bucket Size of
4 , drums triple crimping structure

( 1 ) triple curling. Also known as the seven curling , which is closed steel drums and barrels are bottom of the barrel ( top ) together form the main seaming .
( 2 ) Triple crimping characteristics

① a good seal
② strong engage in impact strength
③ have a higher technological requirements
( 3 ) triple curling structure type
( 4 ) triple curling structural design calculations
5 , drums closure

( A ) closed hoop closure
① Screw type closure of hoops. Forming ring with a screw connection with the ends of the means to achieve a fixed lid .
② leveraged closed hoop . Formed by a lever connected to both ends of the ring , carry handle lid fixing apparatus can be achieved .

( 2 ) screw closure
Screw type closure into cocks , capping of two types .

① cock -type closure

② press pressure sealer

( 3 ) Top Press closure : is divided into two kinds of gland bolts type and style .
① bolt top closure pressure

② gland -type closure
7.2 steel drum manufacturing process
1 , the main material of steel drums
( 1 ) Steel drum material should have the characteristics of

① good plasticity and weldability
② sufficient strength and appropriate hardness
③ good corrosion resistance

( 2 ) materials used cooperage
( 3 ) the choice of plate thickness
2 , steel drum barrel body manufacturing process
( 1 ) Round Closed Cylinder barrel body manufacturing process

① cutting

② edging

③ rolling
④ welding

⑤ flanging
⑥ Corrugated Roll
⑦ bulging ring bars

( 2 ) circular opening drums barrel body processing technology

① bung reel
② bung necking

( 3 ) pails barrel body of the manufacturing process


( 4 ) profiled barrel barrel body of the manufacturing process
3 , the top and bottom of the barrel barrel manufacturing process
( A ) bottom of the barrel manufacturing process
① Shears
② blanking, drawing
③ Tu Sealing glue

( 2 ) barrel top manufacturing process
① flange punching
② locks installed
③ print mark

( 3) The manufacturing process of the lid

4 , sealing combined process
( A ) two heavy curling process Precautions

( 2 ) Triple crimping process
① triple bead molding process
② affect the quality of the main factors triple crimp
5 , inside and outside the spraying process

( A ) The role of surface coating drums
( 2 ) coating process
① air spraying
② airless spray
③ electrostatic spraying method


( 3 ) the spraying process
① surface outside the grounds
② the spraying

( 4 ) Spraying
6 , drums automated production
( 1 ) Barrel latest achievements in automation
① bottom of the barrel and the barrel top automatic molding
② lap portion of the barrel body automatically trimmed cuffs
③ barrel body longitudinal seam welding
④ complex whole testing center
⑤ horizontal painting equipment
⑥ print automatic production system
⑦ drums automatic leak detection system
⑧ warehouse stack system

( 2 ) the future trend of the development cooper automatic
① The opening drums automated production equipment
② automatic printing device
③ mouth piece bucket automatic production line
④ best welding control
⑤ drums of automatic test equipment

7.3 Quality Inspection drums
1 , steel drums quality testing
( A ) Basic requirements

① drums capacity and structural dimensions shall conform to the national standard
② barrel body, barrel top , bottom of the barrel by the entire sheet steel , does not allow splicing
③ barrel body electric overcast seam welds to be used
④ barrel set on top of the form should be based on open

( 2 ) Performance requirements

① steel drums tightness test
② drums hydraulic test
③ drums drop test
④ steel drums stacking test
( 3 ) Quality requirements
① closure assembly quality requirements
② drums external surface protection layer quality requirements
③ appearance quality requirements

( 4 ) the use and maintenance of steel poke
① in the transport , loading and unloading should be a measuring tape to avoid collision, fall and roll
② drums should open dumps , stacking should be set when the underlying cushion , Outdoor should be stamped felt cloth , to prevent the sun, rain and blisters
③ packaging is too flammable , explosive or occurrence of certain toxic substances leaking drums , not welding in order to avoid accidents caused by dangerous
④ recycling reuse drums should be overhauled and painted up to avoid corrosion
2 , steel pails quality inspection
( 1 ) performance , quality requirements
( 2 ) Test method
① structure size and appearance quality
② tightness test
③ hydraulic test
④ drop test
⑤ stacking test
⑥ Ti Liang , put the ring strength test
⑦ film adhesion measurement

( 3 ) transport, storage , precautions
