Pressed Steel Coupler

Pressed Steel Coupler are metal connectors manufactured through a stamping process.They are mainly used in scenarios such as construction scaffolding and steel structure erection to achieve rapid fastening and connection of rods like steel pipes and profiles.Made from steel plates and formed by die stamping,they feature high production efficiency,low cost,and light weight,and are widely used in temporary construction or light-duty structures with medium and small loads.The following is a detailed introduction from aspects such as manufacturing process,performance characteristics,application scenarios,and usage precautions:

I.Manufacturing Process:Stamping Forming for Efficient Mass Production

The core manufacturing process of steel plate stamped fasteners is steel plate stamping.Different from forging or casting processes,its process focuses more on cold processing and shaping of metal plates through dies:

Raw Material Selection:Low-carbon steel plates(such as Q235)are usually used,with thickness varying according to fastener specifications(generally 2-5mm),which have good plasticity and stamping performance.

Stamping Forming:After cutting the steel plate into blanks,continuous stamping(including blanking,stretching,bending,punching and other processes)is carried out through punch presses and special dies to form the main structure of the fastener(such as buckle seat,buckle cover,bolt hole,etc.)in one go,without complicated subsequent processing.

Surface Treatment:To prevent rust,surface treatment is performed after stamping forming.Common methods include galvanizing(cold galvanizing or electro-galvanizing),painting or phosphating to improve corrosion resistance in humid environments.

Assembling Accessories:Finally,fasteners such as bolts and nuts are assembled to form a complete fastener product.

Process Advantages:The stamping process has a high degree of automation,fast production efficiency,and lower cost than forged or cast fasteners,making it suitable for mass production.

II.Performance Characteristics:Balancing Lightweight and Practicality

Lightweight and Easy to Carry:

Formed by stamping thin steel plates,they are lighter than cast iron or forged steel fasteners,making it easier for workers to build or disassemble scaffolding,which is suitable for high-altitude operation scenarios.

Simple Structure and Convenient Installation:

The design focuses on quick operation.The buckle cover and buckle seat are connected by bolts,and the rod can be fixed by tightening the nut,so the installation efficiency is higher than that of traditional cast fasteners.

Low Cost and High Cost-Effectiveness:

The stamping process eliminates the need for complex smelting or forging links,and the raw material utilization rate is high,so the product price has more advantages,which is suitable for temporary construction or light-load projects.

Good Toughness and Not Easy to Brittle Fracture:

Low-carbon steel plates have certain toughness and are not easy to brittle fracture like cast iron fasteners when impacted.However,the load-bearing capacity is limited by the thickness of the steel plate,which is suitable for medium and small load scenarios.

III.Application Scenarios:Focusing on Light-Duty and Temporary Needs

Construction Scaffolding:

Mainly used for scaffolding in low-rise buildings,interior decoration or temporary support,connectingΦ48mm steel pipes to bear the weight of construction workers and light materials.

Temporary Facility Construction:

Such as protective fences,material stacking racks,temporary passages at construction sites,etc.,relying on its advantages of convenience and low cost.

Light Steel Structures:

In the frame connection of small factories and storage sheds,it is used to fix secondary stress-bearing rods to assist in stabilizing the main structure.

IV.Usage Precautions

Avoid Overload Use:

Limited by the thickness and structural strength of the steel plate,its load-bearing capacity is lower than that of forged fasteners.It is strictly prohibited to be used in heavy-duty scaffolding or scenarios bearing excessive loads to prevent deformation or fracture.

Ensure Proper Installation:

During installation,the fastener must be closely attached to the steel pipe,and the bolt must be tightened to the specified torque(generally 20-40N・m)to prevent the rod from loosening and slipping.

Regular Inspection for Wear and Tear:

After long-term use,it is necessary to check whether the steel plate is deformed,cracked or the bolts are loose.For areas where the surface coating falls off,timely painting is required to prevent rust,and severely damaged ones should be replaced immediately.

Avoid Long-Term Use in Harsh Environments:

Its corrosion resistance is weaker than that of hot-dip galvanized forged fasteners.In rainy,humid or chemical environments,the inspection cycle should be shortened to prevent rust from affecting the strength.
