Introduction of Concrete Sleeper Production Machine

Prestressed concrete sleepers production machines consists of sleeper mold cleaning machine , PC bar length fixed cutting machine, button heading machine , tensioning machine,  concete mixing machine , concrete vibration machine , steam curing machine, tension releasing machine, stacking machine, hoisting machine etc.  Below is the description how they works during concrete sleeper production . 

1. Mold Cleaning

This process is mainly to clean residue end and sides of mold and spray powdering agent and meanwhile change damaged parts such as hole supporter.

2. PC steel wire length fixing and button heading and Placed into mold

3.Tensioning and place stirrup clapboard.

4.concrete mixing and pouring

5. concrete vibration and spare concrete removing from mold

6.steam curing 

7. Pre-tension release and mold releasing 

8. concrete sleeper cutting and stacking

9. Finished Products into warehouse

Features

1. Advanced Welding technology, which enhances smooth finish of the mould wall and surface and eliminates uneven traces of rivet holes.The surface of concrete poles  will be improved obviously.

2. The pole mold cylinder is changed to U-type longitudinal stiffeners. This structure can greatly increase the stiffness and flexural strength of the steel mould.

3. Install the slot with rubber sealing strip, in order to prevent leakage to ensure quality.

Concrete Pole Production Process

1. Raw Materials Preparation

prepared raw materials required for the producing of cement poles.Production raw materials include: steel, sand, gravel, and cement.We should choose high quality steel bar, cement that is strong resistance to pressure,choose fast solidification and low density cement.Sand should be filtered to prevent other magazines doping.

2 Steel Cage Forming Process

Use straightening & cutting machine to straighten and cut steel bar in accordance with the provisions. After finishing straightening steel bar,send them to the next program.Please note that the straightening of steel should be cut off according to the length of cement pole. Length should be accurate. It is crucial for the steel bar is equivalent to concrete pole skeleton .

3. Tension Steel Cage 

4. Concrete Distribution Process

Place the steel cages in the open mold .After pouring with cement with concrete distribution machine , cover the cover mould.After confirmation on both sides of the gap smaller or closed, finally plug two sides with pouting lips fortress to prevent the outflow of cement.

5. Centrifugal Spinning

After closing the mold and hoist with crane onto the spinning machines . Then start the spinning process . It will take three different speed regulating steps , totall 15 minutes . At this step , speed variable control cabinet and motor is suggested .

6. Steam Curing 

It's one of most imporatant process for the concrete pole production . With the steam supplying into the steam curing pool by the steam boiler , the concrete poles in the mold will be treated with four hours at least in the pool . At different period , concrete poles will need different temperature .  And at about 86 degree , the temperatue should keep steady .

7. Inspection of Finished Concrete Poles

8. Storage of Qualified Concrete Poles

We supply complete concrete pole machines and be responsible for installation and commissioning and also workers production training service .
