Z15 Manual Alignment H Beam Assembly Machine with Automatic Tack Welding

Feature: Z15 is the most extensive applied model in product family of H Beam Assembly and Tack Welding Machine.

1. Application Features of Manual Alignment and Automatic CO₂ Tack Welding Z15 H Beam Assembly Machine:

1) Working Way: This Z15 hydraulic H Beam Assembly Machine is equipped with function configurations of automatic CO₂ tack welding, and manual alignment of Flanges and web (Manual assembling process): 

Workpiece H Beam of Z15 model machine: (Fig.1) 

2) Function: This Z15 model machine is for producing assembled and tack welded H Beam with max. 1,500mm H Beam web height.

2. Manual Alignment and Clamp of Flanges with Web versus Automatic Way in Z15 H Beam Assembling Machine:

Assembly Operation: As compared with the automatic assembling style of self alignment introduced in the previous product of Z20 self alignment model machine, the similarity and difference between manual alignment and self alignment assembling operation are listed as below:

1) Similarity of Automatic with Manual Assembling:

Quantity of the alignment rollers and their arrangement are the same in the assembling area (eight pieces in one set of machine):

2) Difference of Automatic versus Manual Assembling in H Beam Assembly Machine:

a) Drive way of the eight pieces of alignment rollers:

i. In Self Alignment model machine, it is with oil cylinder on both sides of the H Beam web: (Fig.3)

ii. In Manual Alignment cofiguration machine, it is with one side oil cylinder drive, and the other side by hand operation: A piece of handwheel fit on the lateral side body of the hydraulic automatic machine, and a piece of leadscrew connected with it:

Assembly drive way in semi-automatic manual machine: (Fig.4) 

b) Alignment Operation in Automatic versus Manual Assembling H Beam Assembly Machine:

i. In Self Alignment machine, it is performed automatically, without human intervention;

ii. In Manual Alignment machine, it is with the handwheel mentioned above: By turning it, the leadscrew connected with this handwheel revolves forward, and pushes the four pieces of rollers at this side approaching the web, until contacting with and then being held against the web tightly, thus finishing manual alignment process in the machine with Tack Welding:

c) Advantage of Self Alignment and Manual Alignment flanges and web in hydraulic H Beam Assembly machine:

i.  In Self Alignment machine, the operation is easy and time saving;

ii. In Manual Alignment machine, manual operation can make alignment in fine and precise way.

3. PLC and Inverter Control on Automatic CO₂ Welding Process of Hydraulic H Beam Assembly machine with Tack Welding:

1) Electric Control: PLC and A.C. inverter are the two essential components for realizing automatic CO₂ welding in the machine with Tack Welding: 

PLC in electric control of Wuxi JACK H Beam Assembling Machine: (Fig.7) 

A.C. inverter for controlling working speed of H Beam Assembly and stitch welding: (Fig.8)  

2) Related Equipment: And, Z15 and Z18 hydraulic automatic machine is the solitary equipment among welding H Beam production equipment which utilizes PLC to fulfil its control process: 

As comparison,

H Beam Submerged Arc Welding Machine utilizes A.C. inverter for managing its welding velocity;

H Beam Straightening Machine has constant straightening speed;

3) In this sense, we can say that hydraulic automatic machine is the most sophisticated equipment in the process technology of welding H Beam manufacture;

4) Strong Points of PLC in Electric Control System of H Beam Assembly Machine:

a) Flexible Program Control: As everyone in the industry knows, PLC replaces hard wired relay circuit in controlling working process of machine, by means of editable program embedded in it;

b) Easy Upgrade: To change control logic for H Beam assembly and tack welding, just compile the user program of the PLC, instead of arduous and time consuming redesign of relay circuit;

c) It is very suitable for achieving complicated and flexible tack welding process of the machine.
