Two wave and three wave guardrail profile rolling forming machine either can make two wave guardrail and three wave guardrails in batch fully automatically.

Two wave and three wave guardrail profile rolling forming machine either can make two wave guardrail and three wave guardrails in batch fully automatically. A guardrail is a safety barrier or railing designed to prevent falls, protect motorists, or secure areas, commonly used along highways, rooftops, and staircases. In technology, they act as security layers for DeFi protocols or AI systems, filtering, detecting, and validating content to prevent misuse. In the market, there are two types guardrail: two wave guardrail and three wave guardrail. Here are some drawing profiles for your reference:

Supported material:

1) Material: Q235

2) Steel strip thickness: 2.5-4.0mm

3) Steel strip width: 480mm/740mm

4) Inner diameter of steel coil: φ 508~φ 600

5) Outer diameter of steel coil: ≤φ 1900

6) Steel coil weight: ≤ 10T

How to adjust from two wave guardrail to three wave guardrail?

Compared with three wave guardrail, two wave just wave missing. Punching part, the holes less. So the machine we design, the punching hole parts adjustable. The main rolling forming m-achine simple adjust the input coil width and the leveling beach then okay as the coil narrow and then some rollers are not working. The machine we design using the before shearing, so no need to change the cutting blade. Let us check the guardrail machine working flow:

Two wave and three wave guardrail profile rolling forming machine elements:

10 ton hydraulic decoiler

Material width: ≤ 800mm

Material inner diameter: ø 508mm/ø 610mm

Material outer diameter: ≤ ø 1500mm

Maximum load-bearing capacity: ≤ 10T

Expansion diameter: 480-630 (available with ø 508 material diameter)

Expansion method: hydraulic type

Hydraulic power of uncoiler: 3KW

Uncoiler motor power: 7.5KW

Speed regulation method: Variable frequency drive speed regulation

Is it equipped with a pressure arm

Second part punching and rolling forming machine parts:

Molding machine structure: cast iron memorial archway type gearbox transmission

Leveling mechanism structure: front and rear double roller clamping, seven roller leveling

Leveling shaft diameter: Φ 80mm

Leveling shaft material: 40Cr quenched and tempered (HB220-260)

Surface treatment method for leveling shaft: high-frequency quenching followed by ultra precision grinding and hard chrome plating treatment

Adjustment method for gap between upper and lower rollers: turbine lift adjustment reference image

Punching mechanism structure: Four column hydraulic punching (punching frame steel plate welded and tempered)

Punching mold: 1 set

Punching die upper and lower die material: SKD11 (HRC58-62)

Upper and lower template material: High quality carbon steel quenched and tempered with ultra precision grinding processing

Above design is quite good for those:

(For those ) who need high speed production.

The factory can dig hole for storing coil.

Those who can afford higher cost of machine

For those who hoping that change the hydraulic station and mold more easily for two wave and three wave.

For those who does not have too much space in the workshop and do not need big production, you can choose the following economic design:

Loading (loading the steel coil into the internal support-type cutting frame and tightening it) —– Clamping and leveling mechanism —– Hydraulic punching —– Forming (guiding the steel strip correctly into the forming machine via the feed guiding mechanism) —– Hydraulic cutting —– Unloading
