CHARACTER

1) HOT PRESS

The hot press is composed of press frame, cylinder, hot pressing plates, upper and down beam, inlet & outlet steam water system, hydraulic system, electrical control system.

Each group frame is composed of 2 pcs frame plate. In order to guarantee precision and rigidity , frame is whole piece . Each group frame is processed on large size DC boring-milling machine to guarantee same height of working surface of each group frame.

Chilled cast iron cylinder piston materials, cylinder is ZG500-270 cast steel, the main seals for special customized pieces. Each cylinder should go through a 35MPa high-pressure test. If cylinder in normal usage, the seal life of 3-5 years.

Each hot pressing plate surface go through ground finish to ensure that the hot pressing plate geometric tolerances and surface roughness (finish) requirements (accuracy up to 2 GB). Hot pressing plates adopt Multi-loop inlet and outlet heating structure, saturated overheat water heating to ensure the hot pressing plate surface temperature ≤ 3 °C, the maximum hot pressing plate temperature difference between each layer ≤ 2 °C.

This press can work in the hydraulic oil pressure to ensure 28.0MPa, it means that the press under the pressure of nominal can be used long-term . The user simply presses the start button, the press will complete the entire process automatically according to hot pressig curve set in man-machine interface.

2) loader

pushing carriage to and fro speed ~4.5m/min

horse power ~11kW

max load of each layer cage 2000kg

When Loader load each layer, cage rise one layer , waiting for the next layer raw board loading, followed by cycle, each layer filled up. To wait for pushing carriage to send to hot press for pressing. .

3) unloader

unloader carriage to and fro speed ~5.5m/min

horse power ~11kW

max. load of each layer cage 2000kg

After pressing , unloading carriage pull finished product into the unloader cage, finished hpl in cage will be unloaded by unloading carriage layer by layer, cage drop down one layer when unloading one layer, waiting for unloading carriage unloading . All emptied, the cage up to the initial position, wait for the next time outfeeding board.

4) unloading carriage

pushing board speed ~10m/min

horizontal to and fro moving speed ~10m/min

horse power 3kW

5) back board conveyor I

transporting speed ~10m/min

horse power 1.1kW

To transport working piece to back conveyor II.

6) back conveyor II

speed ~14m/min

horse power 1.1kW

To transport working piece to back conveyor III.

7) back conveyor III

speed ~17 m/min

horse power 1.1kW

To transport working piece to separating board conveyor .

8) separating board conveyor

speed ~20 m/min

horse power 1.1kW

Board will be unloaded by worker and and laid by worker.

9) transit roller conveyor

compressed air consumption ~0.1 m³/min

compressed air pressure 0.6MPa

Cylinder rises transition roller conveyor,transporting cushiod pad will be transported from separting conveyor to planking board conveyor manually.

1 0) planking roller conveyor

speed ~20m/min

horse power 1.1kW

Operation worker plank raw board on this machine and after planking , to send to loading conveyor.

11) loading conveyor

speed ~20m/min

horse power 3kW

To send each layer board to cage of loader.

12) vacuum accetabula carriage

max. working piece weight 300 kg

carriage moving speed ≤65 m/min frequency convertor adjusting speed.

carriage horse power 2.2kW

compressed air flow ≥0.4 m³/min(0.6Mpa)

vacuum pump air-bleed speed 100m³/h(vacuum pump prepared by buyer)

motor horse power 5.5kW

no of accetabula 6 PCS

13) hydraulic system

horse power ~80kW

capacity of oil tank ~9m³

The system uses low-noise , high flow vane pump, ensure press closing time. To ensure the system is reliable, solenoid valves and other hydraulic components adopt top chinese advanced and reliable hydraulic components, the main details of the relevant pieces of table 2. The practical application of this system is reliable and stable.
