Round-to-Square Share-Roller Tube Mill (XZTF)
Product Description
it utilizes the round-to-square technique while allowing customers to use one set of rollers to produce all square pipe range within the set range, and shared-use break-down section rollers when producing round pipe, saving significant roller cost and increase productivity. Combined with our ZTF technique, it allows full automatic adjustment of roller position with minimum to none need of manual adjustment, reducing labor maintenance cost and risk of hazard.
Core description
Our company has studied a new forming process, the technology of ‘Round-to-square without replacing molds’ or XZTF share-roller technique. This most advanced patented technique had won us the ‘Innovation Award for XZTF Round-to-square share-roller forming line’ by ‘China Steel Structure Association’ in 2021.Round-to-square Share-roller tubemachine is designed to produce welded pipes of 114-720mm in OD and 1.5mm-22.0mm in wall thickness, as well as corresponding square and rectangular pipe.
Main Features
To achieve intelligent and flexible manufacturing, three systems are needed:
1. Electronic control system: Highly automated one-button operation.
2. Cloud End System: Data transmission is achieved by connecting PLC main station with network. Data can be monitored and modified on the APP/PC.
3. Mechanical System: Round-to-square Share-roller technique.
A. Highly automated mechanical structure
* The technology of Round-to-square without replacing molds overturns the structure of conventional Round-to-square, connects the roller to the sleeve/stand, drives roll sleeve/rack opening and closing through motor to share rollers.
* Mould sharing is realized through mechanical structure optimization.
B. Highly automated roller quick-change structure
When producing round pipe, hydraulic quick-change system to quickly dissemble transmission shaft
C. Highly automated roller position adjustment
* Precise control and positioning are achieved by using a full range of encoders to control each motor. The data of each roll can be modified and saved through the display.
* During adjustment, the motor will be directly protected against collision and offside, which can avoid serious accidents.
Faster production: Reduce roller switching downtime from more than 8 hours to <2 hours.
Better Structure: Stands with angular adjustment and sliding structure for precision forming.
Easier Operation: 1-button control with servo motor automatic positioning.
Less Cost: Less roller cost, only 1 set of rollers to fulfill all specifications.
Product Advantages
1. Save up to 95% roller cost per one size of desired product.
2. Even inner R angle for square products.
3. No reduced thickness for the rangle compare to direct square forming.
4. Eliminate the incidence of R angle cracking when producing high grade steel tubes.
5. High automatic level.
Committed to cooperate with customers and strive for high-end welding pipe equipment in China.
