Configuring H-beam production equipment by process

From plate strip cutting and main-beam assembly, welding and straightening through hole and slot processing and surface preparation, combine equipment around workpiece size, welding requirements and workshop logistics. This section presents the working principles, model specifications, core configurations and site interfaces of eight equipment groups.

The following configurations are used for scheme comparison. Standard configurations, options, brand models and supply boundaries will be listed one by one in the project configuration table; attachments shown in the pictures are not automatically included in all models.

CNC Flame & Plasma Cutting Machine

1 / 3

01 / Machine description

Cut the entire steel plate into web and flange plate blanks required for H-beam, or process the plate according to CNC graphics. Multiple straight flame torches are suitable for repeating width slitting tasks, and CNC flame or plasma torches are used for contour cutting.

The gantry runs along the longitudinal guide rail, the cutting torch moves along the beam, and the two axes are linked to form a cutting path. Flame cutting uses preheating and oxidation reactions to separate carbon steel; plasma uses an electric arc to melt materials and discharge the molten metal. The two methods are selected according to material, thickness, cutting quality and subsequent assembly requirements.

How key structures function

Mast and bilateral drive

The drives on both sides drive the gantry to walk along the track. The straightness of the guide rail, the rack engagement and the synchronization state jointly affect the stability of long-distance cutting.

Torch and Height Adjustment

The flame cutting nozzle is selected according to the plate thickness and gas; the plasma arc voltage is increased to maintain the cutting distance. Cutting current, gas and consumables need to be matched as a process.

Slitting and CNC contours

The distance between straight cutting torches corresponds to the width of the lath, and the CNC cutting torch executes the contour program; when discharging, the cutting compensation, remaining material, and lath deformation are also considered.

The thickness in the table is the capability data of the corresponding reference configuration, which does not mean that all materials, perforation methods and quality levels can be completed at the same speed. It is necessary to distinguish between edge cutting and perforation in the board, and confirm the process with the target board material.

Core components

**Shanghai Fangling CNC system**The CNC system executes the contour program and motion control, and organizes cutting with seam compensation and process settings.

**Gas supply system**Supply gas to the cutting torch according to the process, and check the gas type, pressure, flow rate and pipeline layout when selecting the model.

**CHINT low-voltage electrical components; Siemens upgrade available**Responsible for power distribution, switching and control loop functions; Chint/Siemens configuration is confirmed according to the project list.

**Guide rail and rack system**Guide long-distance walking and transmit driving force, and the installation accuracy, meshing and cleaning status affect the cutting trajectory.

**Arc voltage height controller**used arc voltage feedback to adjust the height of the plasma cutting torch to maintain the cutting distance required by the process.

**Chengdu Huayuan plasma power source**To power the plasma cutting torch, the power supply, cutting torch, consumables and gas should be selected according to the same process combination.

**CNC flame cutting torch**Perform flame contour cutting, and the cutting nozzle, preheating, and oxygen settings match the material and plate thickness.

**Panasonic drive system**The drive shaft moves and cooperates with the transmission mechanism and CNC instructions to execute the cutting path.

**Gas manifold**Centralize the organization of gas supply and distribution, making it easy to check the gas paths and gas supply status of multiple cutting torches.

**Plasma cutting torch**A plasma cutting process is formed at the workpiece, with electrodes, nozzles and protective parts as key inspection consumables.

Configuration and process connection

Scheme basis

TW-PQC4000 reference configuration is 4 m gauge, 14 m rail length and double-sided drive.
Huayuan 200 A plasma power supply; the combination of 2 sets of CNC cutting torches and 9 linear flame cutting torches is shown in the parameter table.

Project matching and boundaries

The rail length, number and spacing of cutting torches are adjusted according to steel plate specifications, output and workshop length.
Low-voltage electrical appliances can be configured by Chint or Siemens according to the project; the cutting platform and smoke extraction system must be individually checked for scope of supply.

Upstream incoming materials: Steel plate warehousing and loading; provide plate width, steel number, plate thickness combination and target strip size.
Downstream processes: After slag removal and checks of dimensions and cut-edge quality, move the blanks to assembly or integrated assembly, welding and straightening. Supply contour files for tapered webs.

Site interfaces and maintenance points

Site utilities and interfaces

Check the track foundation, lifting coverage, power supply and grounding, oxygen and gas, gas source required for plasma, smoke extraction and slag cleaning space. The air source pressure and flow rate are subject to the selected equipment file.

Maintenance focus

Monitor cutting-nozzle and electrode wear, gas-line seals, rail cleanliness and torch-height control each day. If cut-edge bevel or slag changes, check the process and consumables first.

Bring workpiece drawings, common specifications and production requirements to obtain corresponding configuration and layout suggestions.

01 / Machine description

Used for batch cutting of supporting plates, connecting plates, stiffening plates and other supporting plates for steel structures. Production is organized based on plate drawings and nesting materials, and can be operated in parallel with the main beam welding line, and materials are supplied to the assembly station according to the project rhythm.

The fiber laser is focused onto the surface of the plate through the cutting head, the auxiliary gas discharges the molten material, and the CNC system coordinates the cutting head trajectory and processing parameters. The selection should also look at the common board width, material thickness combination, perforation ratio and target cut-edge quality, not just the laser power.
