Description

The necking machine of PLC control

Technical field:

The utility model relates to packing container production equipment control technology field, refers in particular to a kind of PLC control section that carries out reducing, flange, rolls the necking machine of muscle.

Background technology:

Reducing is very important in the manufacturing process of steel drum, is one important operation of steel drum moulding, and the speed of necking forming, quality have determined efficient and the quality that steel drum is produced; At present, the reducing that domestic most of manufacturers adopt all is single a bung or a bucket end to be carried out reducing, can not realize reducing, flange, roll muscle and on same necking machine, finish, and, all adopt the pattern mode of cam control to finish during reducing; Make that the hold facility place is big, the feed velocity of cam is very slow, causes speed of production slow; Part realizes the machine that reducing, flange, ripple carry out with machine, and also because its feed is slow, and production efficiency is low; And, because action is more, under the situation of manually control, misoperation appears easily, tubbing is scrapped, and security incident also appears easily, and operator's labour intensity is bigger, and is higher to operator's competency profiling, increased production cost.

Summary of the invention:

The PLC control structure that provides an a kind of material loading can finish reducing, flange, roll the necking machine of muscle is provided the purpose of this utility model.

The utility model is achieved by the following technical solution: the PLC control section of control necking machine action is connected on the fuselage; PLC control section control feed cylinder and hold out against the action of cylinder, thus shaping roller controlled, hold out against the advance and retreat of dish; Connecting with switch X1, relay R 2 normally-closed contacts, relay Y4 after switch X0 and the parallel connection of relay Y4 normally opened contact in the described PLC control section is one the tunnel; The normally-closed contact T0 of switch X2, switch X1, relay R 2 normally-closed contacts, relay TMX0, relay R 0 series connection are one the tunnel; Switch X2, relay R 2 normally-closed contacts, relay TMX0 series connection are one the tunnel; Relay R 0 normally opened contact is connected with relay R 5 normally-closed contacts, and relay Y0 normally opened contact is connected with relay R 2 normally-closed contacts, and last two branch roads and SRE Y0 after switch X3 is in parallel are as one the tunnel; Relay Y0 normally opened contact, relay R 2 normally-closed contacts, relay TMX2 series connection are another road; In parallel with switch X4 after relay TMX2 normally opened contact T2, the series connection of relay R 2 normally-closed contacts, connecting with relay R 5 normally-closed contacts, relay Y1 then is one the tunnel; Switch X7 is one the tunnel with SRE TMX1 normally opened contact T1, relay R 2 normally-closed contacts, relay R 5 after relay R 5 normally opened contacts are in parallel; Relay R 5 normally opened contacts, relay R 2 normally-closed contacts, relay TMX1 series connection are one the tunnel; SRE Y2 is one the tunnel after relay R 5 normally opened contacts, the switch X5 parallel connection; SRE Y3 is one the tunnel after relay R 5 normally opened contacts, the switch X6 parallel connection; Switch X1, relay R 2 series connection are one the tunnel; Relay R 2 normally opened contacts, relay Y7 series connection are one the tunnel; More than each branch road be in parallel.

The utility model by PLC control section control feed cylinder, hold out against the action of cylinder, thereby control shaping roller, hold out against the advance and retreat of dish, and whole reducing, flange, the process of rolling muscle make the running of necking machine realize control automatically; Greatly improve the speed of moulding, shaping speed can have been brought up to 7-8/minute by a 3-4/minute kind of eccentric feed mode, reached as high as 9/minute; And in the process of processing, people's workload is little, has alleviated the intensity of work, has also avoided the generation of faulty operation, guarantees the safety of producing, and improves the qualification rate of product.
