The keel machine is a cold rolling machine that uses strip steel as raw material to produce complex cross-sectional profiles (including light steel keels, painted keels, card keels, various building profiles, steel structures, steel lined door frame profiles, high-speed guardrails, etc.) and cold bending and painting units of different specifications. It is controlled by PLC.

Characteristics of high-speed keel machine:

1. Rolling capacity of the unit: width ≤ 150mm, plate thickness 0.6-2.0mm

2. Production speed: 6-13 meters per minute

3. Total installed capacity: approximately 5.5kw

4. Production area: 15 meters long X 2.5 meters wide

1. The equipment is controlled by PLC and multiple protections are set during normal production.

2. The bed is made of welded steel plates. And carry out tempering treatment to reduce internal stress and avoid deformation of the aircraft body.

3. The molding frame is made of cast iron structure and has undergone tempering treatment. High strength and long service life.

4. The material of the rolling mill shaft is 40Cr and has undergone quenching and tempering treatment, with a hardness of HB280.

5. The material of the molding mold is GCr15, quenched, and the hardness is HRC56-62 ℃.

6. The transmission structure is a gearbox transmission. Each molding rack is equipped with a light steel keel machine. The device is capable of exceeding the time limit, running smoothly, and has a long service life.

The processing technology of high-speed keel machine: feeding - straightening - rolling forming - cutting - receiving

The high-speed keel machine equipment consists of a feeding machine, a guide frame, a forming host, a calibration device, a cutting section, a receiving platform, and an electrical control section.
