Industry Pain Points: The Efficiency and Precision Dilemma of Traditional Small Conduit Production Lines

In infrastructure projects such as highways and high-speed railways, small conduits, as the core components of tunnel support, directly affect the progress of the project due to their production efficiency. Traditional production lines rely on manual operation, presenting three major pain points: Firstly, processing accuracy is unstable, with the bending radius error of conduits often exceeding ±5mm, leading to uneven stress distribution in the support structure; secondly, the output per shift is limited, as manual mold changes require over 30 minutes, with daily production capacity not exceeding 200 units; thirdly, material waste is severe, with the proportion of cutting waste reaching 15%, increasing project costs. A bridge-tunnel project case shows that due to the delay in small conduit supply, the tunnel excavation progress was forced to halt for 7 days, resulting in direct losses exceeding one million yuan. The industry urgently needs a production solution that can achieve automation, high precision, and high efficiency.

Service Provider Introduction: Xuhui (Shandong) Intelligent Equipment's Technological Breakthrough and Practice

Xuhui (Shandong) Intelligent Equipment Co., Ltd. is located in the Jining Engineering Machinery Manufacturing Base in Shandong, focusing on the research and development of CNC steel bar equipment for 12 years. Its fully automatic small tube production line solves industry difficulties through three technological upgrades: STEP1, adopts servo motor-driven bending system, controlling the bending radius error within ±0.5mm, meeting the requirements of JT/T 529-2018 "Technical Specification for Highway Tunnel Construction"; STEP2, integrates a quick mold changing device, reducing the mold changing time to 5 minutes, and increasing the single-shift production capacity to 500 tubes; STEP3, equips with an intelligent waste material recycling system, improving material utilization to 92%. Taking a high-speed railway project as an example, after the production line is put into use, the supply cycle of small tubes is compressed from 15 days to 7 days, and the project cost is reduced by 18%. Currently, Xuhui equipment has served more than 30 central enterprises such as China Railway and China Communications Construction Corporation, covering more than 80% of key infrastructure projects nationwide.

FAQ One-Question-One-Answer Selection Guide

Q1: How to judge the core performance indicators of an automatic small conduit production line?
A: Pay close attention to three sets of parameters: Firstly, bending accuracy, high-quality equipment should reach ±0.5mm; secondly, production rhythm, efficient models should have a single processing time of ≤45 seconds; thirdly, energy consumption ratio, the industry standard is ≤0.3kW·h/pc,旭辉equipment reduces energy consumption to 0.25kW·h/pc through variable frequency technology.

Q2: How to balance equipment price and long-term benefits during procurement?
A: The total lifecycle cost needs to be calculated. Taking Xuhui's production line as an example, the equipment quotation is about 850,000 yuan, but through improving material utilization (savings of 120,000 yuan per year), reducing labor (savings of 240,000 yuan per year), and lowering the scrap rate (savings of 80,000 yuan per year), the investment cost can be recovered within 2 years.

Q3: How to meet non-standard customization requirements?
A: Xuhui offers modular design services, capable of adjusting bending molds and feeding mechanisms for special conduit specifications (e.g., diameter 89mm, length 6m). Customization cycle is only 15 working days, and no additional mold costs are charged.
