When the used ERW tube mills is used to make welded pipes, the judgement of the qualified quality of the welded pipe depends on the control of the squeeze roller, so the control of the squeeze roller is very important. There are many ways to control the squeeze roll, and "up two next one" is the squeeze roll methods.

 

Used ERW tube mills

The "up two next one" three-roll extrusion method can be said to be the best extrusion method for small pipe diameter welding (steel pipes below 114mm) in the used ERW tube mills. Three-roller independent adjustment, three-roller unified adjustment and overall rotation make the adjustment consistent. The three squeezing rollers each cover nearly 120 degrees, and the diameter and load-bearing capacity of each roller are effectively reduced. Vee length = pipe diameter, which is the most efficient. The upper two rollers effectively fit the edges of the steel strip in an angle form, forming a good squeezing force and controlling the edges of the steel strip. Many disadvantages of the two-roller and the top three-roller are avoided, so it is an ideal welding extrusion device.

 

The disadvantage is that the technical requirements, processing accuracy requirements and cost are relatively high, and adjustments are more difficult at the same time, which limits the promotion. It is usually used on steel pipe lines with higher requirements.

Analysis of a double-head uncoiler:

Analysis of Double-Head Uncoiler Introduction:
A double-head uncoiler is a crucial piece of equipment in metal processing industries. It is primarily used to feed metal coils into roll forming machines, cut-to-length lines, or slitting lines. The double-head design allows for continuous operation by enabling one coil to be loaded and prepared while the other coil is being processed.

Key Components:
1.Mandrels:The double-head uncoiler features two mandrels, each designed to hold and unwind a coil of metal. These mandrels are typically hydraulic or motor-driven to control the unwinding process.
2.Coil Carriages:These assist in loading and unloading coils onto the mandrels. Coil carriages help to position the coils correctly and securely.
3.Hydraulic System:This system is used to expand the mandrel to grip the inner diameter of the coil securely.
4.Control System:The electronic control system automates the switching between coils and ensures synchronization with the subsequent processing line.
5.Brake System:To control the speed of uncoiling and ensure smooth feeding into the processing line, a braking system (mechanical or pneumatic) is integrated.

Operation:
1.Loading:One coil is loaded onto a mandrel with the assistance of a coil carriage. The hydraulic system secures the coil.
2.Preparation:While one coil is being processed, the second coil can be prepared on the other mandrel.
3.Uncoiling:The control system manages the unwinding process, adjusting speed and tension to match the requirements of downstream equipment.
4.Switching Coils:Once the first coil is nearly depleted, the system can seamlessly switch to the second coil, ensuring continuous operation without stopping the line.
Advantages:
1.Continuous Operation:Allows for non-stop processing as one coil can be prepared while the other is being used.
2.Increased Efficiency:Reduces downtime and increases overall productivity in the metal processing line.
3.Improved Safety:Automated systems reduce the need for manual handling of heavy metal coils.
4.Precise Control:Advanced control systems provide precise management of coil unwinding, contributing to product quality and consistency.

Applications:
Double-head uncoilers are widely used in industries such as:
- Steel production and processing- Automotive manufacturing- Construction material production- Electrical appliance manufacturing Conclusion:

Analyzing of High-frequency quenching equipment
Analyzing of High-frequency quenching equipment
High-Frequency Quenching Equipment AnalysisHigh-frequency quenching equipment is advanced machinery used in the heat treatment of metals to improve their hardness and wear resistance. This method involves heating the surface of a workpiece to a very high temperature using high-frequency electric currents, followed by rapid cooling (quenching). The process effectively enhances the mechanical properties of the metal components, making them suitable for high-stress applications. Here are some key points to analyze high-frequency quenching equipment:

1.Working Principle:
High-frequency quenching equipment utilizes induction heating, where alternating electromagnetic fields generate heat within the metal workpiece.
The frequency of the alternating current is typically between100 kHz and500 kHz, which effectively heats the surface rapidly while keeping the core relatively cool.

2.Components:
Power Supply:Generates the high-frequency current necessary for induction heating.
Induction Coil:The coil is designed to fit around or near the workpiece, creating a magnetic field that induces eddy currents on its surface.
Cooling System:Typically, a coolant (such as water or oil) is sprayed or immersed to rapidly cool the heated metal surface.
Control System:Manages the operation, regulating the frequency, heating time, and cooling process to achieve desired material properties.

3.Advantages:
Precision:High control over the heating parameters allows for localized hardening of specific areas without affecting the entire workpiece.
Efficiency:Fast heating and cooling cycles reduce overall processing time.
Consistency:Achieves uniform hardening across the treated surface, improving the reliability and performance of components.
Energy Savings:Induction heating is highly energy-efficient, converting electrical energy directly into heat within the material.

4.Applications:
Automotive Industry:Used to harden components like gears, crankshafts, camshafts, and drive shafts.
Aerospace:Treats critical parts such as turbine blades and landing gear components.
Tool and Die Making:Enhanced hardness and durability of tools such as cutting tools, punches, and dies.
Machine Parts:Hardening of various machine parts, including spindles, rollers, and bearings.

5.Maintenance and Safety:

6.Post-processing (if necessary)
Deburring: Some cut tubes might require deburring to remove sharp edges.
Cleaning: The workpieces could require cleaning to remove any residual material or dirt.

7. Inspection Dimensional Inspection: Quality control checks the dimensions of the cut pieces to ensure they match the required specifications.
Surface Inspection: The surface quality is also inspected to ensure there are no defects or damages that might affect the product's functionality or appearance.

8. Packaging and Shipping Packaging: The finished tubes are packaged to prevent damage during transportation.
Shipping: The packaged tubes are then prepared for shipping to the customer or for further processing.
