A. Introduction

First of all, thank you for choosing our products. Before installing, operating, maintaining and inspecting the equipment, please read this "User Manual" in detail to give full play to the functions of the equipment and ensure the safety of the product.

The schematic diagram of this user manual is for convenience. Due to product upgrade and other reasons, it may be different from the actual product. Please refer to the actual product.

B. Safety precautions

1. The operator must be familiar with the performance, characteristics and operating conditions of the equipment, and check whether the grounding wire is connected correctly and reliably before closing.

2. After the device is powered on and before starting, check whether the parameters of the touch screen are set correctly. The upper limit of pressure for 40t model is 400KN (40 tons), and the upper limit of pressure for 60t model is 600KN (60 tons). When using the device, avoid setting the upper limit value.

3. Check whether the beam is closed before pressing the sample. After closing the beam, ensure that the concave of the beam is completely stuck into the convex head of the column, the mold indenter is correctly placed in the mold, and the screw is screwed against the mold indenter before starting the sample pressing.

4. Pay attention to the pressure indicator of the pressure gauge during the sample compaction. Press the stop button immediately when the 40t model reaches 28Mpa and the 60t model reaches 30Mpa.

5. Pay attention to the pressure of the mold during the sample, and press the stop button immediately if any abnormality is found.

6. Before the device is connected to the power supply, ensure that the voltage used is consistent with the voltage required by the device, and ensure that the rated load of the power switch is greater than the device requirements;

Special reminder: The power supply of this machine is 50HZ/three-phase 380V power supply, and the power cable of the equipment is: three fires and one ground (in which the yellow-green two-color wire is the ground wire).

F. Equipment installation

First step

Place the equipment horizontally on a solid and flat ground, open the side door of the machine, and add No. 46 hydraulic oil to the oil level gauge 2/3 (hydraulic oil customer's own).

The second step

The power supply of this equipment is three-phase 380V with a power of 1.1KW. The random power cable is three phase wires and one ground wire (the ground wire is a two-color wire). A three-phase circuit breaker with leakage protection is required for this equipment. The three phase wires of this equipment are respectively connected to the three terminals of the three-phase circuit breaker, and the ground wire and the ground end are reliably connected to ensure the safety of electricity consumption.

Open the circuit breaker, supply power to the equipment, open the press machine, push the beam, remove the mold indenter, press the release button to check whether the piston rises, if it rises, the motor test is normal, if not, close the three-phase circuit breaker, and adjust any two of the three phase lines before testing.

G. Touch screen parameter setting

Enter the touch screen control interface:

1. The setting of pressure holding time: that is, the setting of the sample pressure (maintain pressure) time within the set pressure value.

2. Setting of pressure relief time: that is, setting of the time used by the pressure relief valve during the pressure relief process after the sample is held. Example: The pressure relief time is 1.5S, that is, the pressure relief valve starts to stop after 1.5S of pressure relief. The purpose is to release part of the pressure in advance when the piston is reset and lowered. The setting time is long and the pressure is released more.

3. setting of reset time: that is, the time of the piston descending walking process after the end of the pressure holding, for example, the reset time is set 5S, that is, the piston stops after walking down for 5S, and the setting time is long and the descending stroke is large. This setting is mainly used to control the stop of the piston after the end of the pressure holding is returned to the appropriate position in the mold.

4.: Real-time display of the pressure value of the sample.

5.: Click to enter other parameter settings.

6.: Click to change to manual control.

Boric acid mold/aluminum cup mold parameter settings are referenced as follows:

Pressure holding time: 30S;

Pressure relief time: 3S;

Reset time: 1S;

Steel ring mold parameter settings are referenced as follows:

Pressure holding time: 30S;

Pressure relief time: 2S;

Reset time: 5S;

Plastic ring mold parameter setting reference is as follows:

Pressure holding time: 30S;

Pressure relief time: 1S;

Reset time: 6S;

7. Holding pressure setting value: the maximum pressure value required for pressing samples; the maximum limit of this machine is 400KN; overload use is prohibited.

8. Compensating pressure setting value: when the pressure reaches the maximum pressure value and then the pressure naturally drops to the compensating pressure setting value, the program will pressurize again to compensate the pressure to the holding pressure value.                  

9. 40T cylinder diameter: 135mm; 60T cylinder diameter: 160mm.

10. Sensor AD value/compensation: default setting.

11. Demolding pressure setting value: that is, the sample is demolded after the pressing is completed, and the rising process does not exceed the demolding pressure setting value.                                                         12. Rise time setting value of demolding: that is, demolding will be carried out after the sample pressing is completed, and the piston will stop rising when it rises to push out the sample and reaches the rise time setting value of demolding.

13. Demolding holding time set value: when the piston rises to the demolding rise time set value, the piston stops rising, at this time the operator to take away the pressed samples, clean up the dust, demolding holding time set value that is: take away the samples, clean up the time required for the dust, when it reaches the set value of the time, the piston will automatically fall, waiting for the next sample pressing.

14. The set value of demolding and descending time is: the time for the piston to descend, and it will stop descending when it reaches the set value.

Note: Do not use the demolding button when using the steel ring mold, forced demolding will damage the mold or cause other losses.
