Z15~Z20 High Quality H Beam Assembly Machine with Tack Welding

Quantity:

With this section we wrap up introduction on product family of H Beam Assemble machine with Tack Welding.

 

As summary, there are variations in models of this series of product, in terms of

   1) H Beam size (Z15/Z18/Z20);

   2) Assembly process (Web and Flange Self- Alignment versus Manual Alignment);

   3) CO2 Tack Welding (Automatic with 2 sets of Gas Shielded Welding Power Source versus Manual);

The combination of these options sets up series of I Beam Assemble and Tack Weld equipment to choose from.

 

Generally speaking, comparison between manual and automatic welding H Beam Assemble machine,

     1. With the same size of H Beam, automatic (both assembly and welding) H Beam Assemble and Tack Weld

         machine has 15% higher price than that of Manual machine;

    2. Still, we recommend automatic equipment to customer more than manual, because of the reasons mentioned

       in the former sections of:

       1) One set of automatic welding I Beam Assemble machine needs only one operator to take care production

          process, instead of two operators for manual machine;

       2) Requirement on operator of automatic machine is not as strict (or high level) as manual machine, on the 

         aspect of skill and experience;

       3) Automatic I Beam Assemble and Tack Weld machine delivers finished H Beam with quality far more stable

          and consistent, so that less inspection work involved;

       4) More flexible in terms of control logic, for future expansion or update, because of PLC soft control, instead

          of hard-wired relay circuit;

       5) In this sense, the automatic Welding H Beam Assemble equipment can pay for itself more quickly than 

          manual machine;

    3.  Of course, the manual H Beam Assemble and Tack Weld equipment also has its advantage, for example:

       1) Better utilization rate on CO2 welding power source: Customer can use the existing power sources of their

           own, instead of 2 sets of brand-new as in the case of automatic welding I Beam Assemble equipment;

       2) If there exists problem with PLC program, one batch of unqualified H Beam may be produced, compared 

           with possibly only one or two pieces for manual machine. This is the reason we suggest customer to have

           trial run in Single mode first before transferring to AUTO cycle.


Hydraulic System

Hydraulic

      1) From the perspective of control and power, the Z15~Z20 I Beam Assemble machine with Tack Welding is

         essentially controlled with electric PLC& inverter, and powered with hydraulic cylinder. So, its hydraulic 

        system is of vital importance;

       2) Hydraulic system is composed of pump station, cylinders and piping;

       3) For Z15~Z20 automatic welding H Beam Assemble machine, downward pressing roller, web &flange 

         positioning &clamping unit, web& flange terminal alignment unit, pulling rod system, arc guiding unit are all

         controlled with hydraulic system;

       4) Downward pressing roller, alignment unit and arc guiding unit are all started with hydraulic cylinder directly;

       5) The hydraulic cylinder for driving the downward pressing roller has long stroke;

       6) To cater for pressing down H-beam web of various specifications, usually it is necessary to add an extension

           shaft at the front end of piston rod of the cylinder;

        7) For web and flange clamping units, there are 2 sets of hydraulic cylinders pushing in the succession of rack-

            gear-sprocket-chain-lead screw-nut, and finally driving the clamping rollers, fulfilling the task of web& 

            flange positioning and clamping;

        8) Web and flange clamping units work in-phase;

        9) Components of hydraulic system are of standard ones, and equipped with fine filter, ensuring long and 

           reliable performance of solenoid valves.
