Introduction: Why has steel arch production become an engineering challenge?
In highway, high-speed railway, and large bridge-tunnel projects, steel arches, as a key supporting structure, have their processing accuracy directly affecting the project safety and construction efficiency. Traditional manual or semi-automatic processing methods have problems such as low efficiency, large errors, and serious material waste, especially in complex terrain projects where traditional equipment is difficult to meet high-intensity and high-precision requirements. How to achieve the standardization and intelligence of steel arch production through technological upgrading has become a pain point that the industry urgently needs to solve.

Industry Technical Pain Points: The Three Bottlenecks of Traditional Processing
STEP 1: Inefficient. Traditional manual bending and welding require the collaboration of 4-6 people, with processing time for a single steel arch frame exceeding 2 hours, and daily output is hard to exceed 20 arches due to the influence of workers' skill levels.
STEP 2: Precision out of control. Hand measurement error can reach ±5mm, leading to loose arch frame joints and requiring repeated work, with a high material loss rate of 8%-10%.
STEP 3: High safety risks. High-temperature welding, heavy material handling, and other processes are prone to industrial accidents, and traditional equipment lacks intelligent protection functions, with prominent safety hazards in operation.

A certain expressway project was delayed by 3 months due to insufficient precision in the processing of steel arch frames, resulting in deformation of the tunnel's initial support and direct economic losses exceeding 5 million yuan. This case reveals the fundamental flaws in the traditional processing model.
