Precision First! How Gantry Welding Machines Achieve Millimeter-Level High-Precision Welding

With the continuous advancement of industrial automation, many tasks that were once done manually can now be performed by machines. Among the wide range of automated welding equipment options, how do you choose a high-precision welding machine that meets your customers' needs? For example, if a customer requires the production of mesh panels with small weld seams, tight welding joints, and high precision to meet strict dimensional tolerances, which automated welding system can deliver?

Let us introduce you to Jinchun’s "Transformers" of welding—the Gantry Welding Machine.

 

1. Equipment Features

This gantry welding machine is specifically designed for customer products and offers the following standout features:

A. Welding Mechanism:

The welding structure allows for horizontal spacing adjustments.

The lower electrode’s stroke is adjustable to compensate for wear and maintain efficiency.

The lower electrode automatically lifts to avoid clamps during table movement.

B. Welding Power Supply:

Equipped with a 125KW AC power supply for welding.

Features a microcomputer resistance welding controller for setting, storing, and controlling welding parameters.

Each controller can store 15 welding programs, providing ample options for different welding needs.

C. Control System:

The core control unit is a Programmable Logic Controller (PLC) with a liquid crystal touch screen as the human-machine interface.

The system controls both the welding host and the automatic feeding mechanism.

Functions include manual/automatic modes, welding method selection, step feeding, teaching programming, data programming, work monitoring, alarm information display, clock, work cycle, production statistics, I/O monitoring, and error prompts.

Can store 10 programs (50 steps per program), offering great operational convenience and flexibility.

 

2. Functional Description

A. Adjustable Pressing Mechanism and Lower Electrode:

The pressing mechanisms and lower electrode can be adjusted horizontally based on workpiece requirements.

Each electrode has its own pressing mechanism, allowing for precise spacing adjustments.

The lower electrode’s stroke is adjustable to compensate for wear, ensuring consistent efficiency.

The lower electrode automatically lifts to avoid clamps during table movement.

The fixture travel speed can reach up to 1800mm/s, with an electrode stroke of 60-80mm.

B. Equipment Composition:

The machine consists of a welding power supply, transformer, feeding mechanism, welding pressing mechanism, positioning fixture, pneumatic system, cooling water system, and control system.

C. Welding Transformer:

Equipped with an AC welding transformer, compact in size, providing stable current and high-quality welds.

D. Welding Pressing Mechanism:

The cylinder generates pressure for welding, with linear guidance for precise and stable electrode movement.

Cylinder pressure is controlled by a pressure regulator.

The upper electrode uses an structure for easy replacement, reducing waste.

The T-slot installation method allows for the use of different-sized electrodes, accommodating various workpieces.

Both upper and lower electrodes can be finely adjusted for precise welding.

E. Fixture Positioning:

The workpiece is positioned using an external pressing method, making it easy to load and unload.

F. Pneumatic System:

Cylinder pressure is controlled by a pressure regulator, with air treatment including pressure regulation, filtration, and lubrication to extend cylinder life.

G. Cooling Water System:

Cools the transformer, control box, and electrodes to ensure the power supply’s longevity.

Equipped with a flow alarm to prevent operation without cooling water.

The cooling water is circulated and filtered to prevent clogging.

H. Control System:

The main components’ movements and adjustments can be directly set and controlled via the human-machine interface.

Faults trigger alarms and are indicated by warning lights.

The entire machine is controlled by a PLC for seamless operation.
