Two, Business Challenges

Engineering machinery is an essential component of the equipment industry. In general, any mechanical equipment required for comprehensive mechanized construction projects in earthwork, road construction and maintenance, mobile lifting and handling operations, and various construction projects is referred to as engineering machinery. Engineering machinery equipment primarily includes excavating machinery, earthmoving and transport machinery, construction lifting machinery, industrial vehicles, compaction machinery, pile-driving machinery, concrete machinery, and 18 other categories of products.

With the rapid growth in the production and consumption of pipes in China, pipe processing technology has also developed rapidly, especially with the emergence of laser tube cutting machines, which have brought unprecedented qualitative leaps in pipe processing. CNC laser tube cutting machines are specialized equipment for cutting and processing pipes. They can efficiently and accurately cut metal round pipes, square pipes, rectangular pipes, angle steel, channel steel, I-beams, and other sectional pipes.

The laser tube cutting machine utilizes mobile and fixed chucks to hold the pipe material in a rotating motion. It achieves cutting by moving the cutting head relative to the pipe material in width and height, along with the feeding motion of the mobile chuck, forming the cutting path.

Faced with the pipe forming needs of domestic and international customers, laser cutting of pipes has gradually become their preferred choice. Industries such as sports equipment, lighting, construction machinery, agricultural machinery, home furnishings, and kitchen and bathroom appliances all require pipe cutting and shaping. Traditional pipe cutting methods mainly involve the use of roller cutters and sawing machines, both of which have significant drawbacks. Using these traditional methods results in complex processes, difficulties in positioning, low processing precision, poor processing quality, and requires more manpower.

With the increasing demand for corporate innovation, upgrades in environmental standards, and the need for labor substitution, the customer in this case wishes to purchase a laser tube cutting machine to replace their existing sawing and drilling equipment. The traditional material preparation method involves cutting on the sawing machine, cutting two segments at angles with a circular saw, and drilling on a drilling machine, requiring three separate processes.

The main challenges for Yawei Corporation in this demand are as follows: achieving automation, integrating functions such as information collection, loading, pipe material recognition, length measurement, automatic program invocation for cutting, weld seam recognition, unloading, stacking, and shipment into a single system, ultimately realizing an intelligent pipe material solution.

Three.Solution

The YLT series CNC laser tube cutting machine is the result of years of research and innovation by Yawei Corporation, integrating the latest international laser technology. It is the most cost-effective laser tube cutting product on the market.

This is the solution.

It features a horizontal gantry bed, a high-strength, lightweight crossbeam optimized through finite element analysis, equipped with high-rigidity precision reducers, a complete set of ground gears and racks, and precision linear guides from Japan's THK for efficient transmission mechanisms. It is equipped with an IPG fiber laser (optoelectronic conversion efficiency ≥40%) and integrated with the YAWEI NCYT50 system for faster speeds and higher efficiency, meeting the needs of various industries and customers.

1. Servo Material Feeding Device

During the cutting of pipes, auxiliary support is provided to prevent cutting quality issues caused by the vibration of long pipes during the rotation process. A single motor drives multiple floating supports to move simultaneously through a linkage mechanism.

2.Intelligent Servo Unloading System

The servo motor control console adjusts the table surface height in real-time to provide continuous support for the finished workpiece. Pipe precision compensation technology adjusts the fixed clamp axis based on the pipe section to limit swinging of the finished workpiece from side to side

3.Pipe Precision Compensation Technology

The pipe bending and twisting compensation function based on the cutting head's follow-up sensor offers advantages over auxiliary sensors like probes. Since the follow-up sensor is non-contact, it provides high detection efficiency and eliminates the need for additional equipment costs.

4.FMC Fully Automatic Feeding System

The feeding device consists of multiple sets of feeding mechanisms, capable of continuously loading one bundle of pipe materials at a time. The bundled materials are first lifted onto the base platform by a conveyor belt and then separated by a double-chain mechanism to ensure that only one pipe remains on the second set of chains. The entire feeding process involves a series of actions including lifting, measuring, clamping, and feeding.

The feeding detection device checks the length of the pipe material. It is driven by a servo motor to synchronously measure the length of the feeding pipe material using a toothed belt, ensuring that the feeding chuck can accurately and rapidly reach the clamping position. Additionally, it allows the operator to access specific data about the pipe material to be processed.

5. Unloading and Stacking System

The finished cut pipes slide down from the cutting slope onto the conveying device.

The conveying device transports the finished workpieces until the signal is detected by the pipe-in-place sensor.

The pushing cylinder pushes the pipes into the buffer area.

The stacking robot arm sorts and stacks the finished workpieces.

Four.customer benefits.

Compared to traditional cutting methods, the advantages of laser pipe cutting machines mainly include high cutting speed and high processing precision.

(a)High precision, fast speed, narrow kerf, small heat-affected zone, and smooth cutting surface.

(b) Good processing flexibility, it can also cut pipes and other non-standard materials.

(c) It can perform non-deforming cutting on materials of any hardness.

Fast cutting speed: Laser pipe cutting machines have a cutting speed that is more than 10 times faster than a sawing machine, which directly translates into economic advantages in terms of laser cutting efficiency.

High cutting quality: Traditional metal cutting methods like sawing and drilling have a significant limitation in terms of material loss and cutting quality. Typically, they require secondary processing and still lack precision. Laser pipe cutting machines, on the other hand, minimize material damage because they are non-contact machining processes that result in one-step forming, eliminating the need for secondary processing. They also offer higher precision compared to sawing and drilling processes.

Are you still complaining about difficulties in hiring workers, labor shortages, low efficiency, and having a small factory space?

Faced with the wave of transformation in the Industry 4.0 era and the development trends outlined in China's "Made in China 2025" strategy, XCMG Construction Machinery has taken the lead in embracing change and modernizing. In alignment with the core concept of high-quality manufacturing development in the 14th Five-Year Plan, XCMG has undergone transformation and upgrades. They have implemented a fully automated pipe sorting and processing center, featuring intelligent loading, sorting, and unloading.
