First, brief introduction

The WEW-600B type machine is mainly used for tensile tests, compression and bending tests of metallic and non-metallic materials. The machine is equipped with computer, printer, electronic extensometer, photoelectric encoder and general test software. It can accurately determine tensile strength, yield strength, non proportional extension strength, elongation, elastic modulus and other mechanical properties of metal materials. The test results can be used to query and print (force displacement, force - deformation, stress - displacement, stress - deformation, force time, deformation time) of six curves and related test data, which have the function of software self inspection, can diagnose the fault automatically, and see the software description in detail. It is an ideal testing equipment for industrial and mining enterprises, scientific research institutions, tertiary institutions, and engineering quality supervision stations.

Two, equipment parameters and configuration

Three. The description of the scheme

1. Host

The main engine adopts the cylinder under the main engine, and the drawing space is above the main engine. The compression and bending test space is located between the lower beam and the worktable of the main engine. The whole machine is shown as shown in Figure 1.

2. Transmission system

The lower beam is driven by the motor through the reducer, chain transmission mechanism and screw pair to realize the adjustment of drawing and compression space.

3. Hydraulic system

After the oil pump is sucked into the oil pump through the filter oil net, the oil pump is sent to the oil delivery valve by the oil pump. When the oil hand wheel is closed, the piston is pushed open because of the oil pressure. The oil flows back to the oil tank. When the oil hand wheel is opened, the oil enters the working oil cylinder via the tubing and then passes the oil through the pressure tubing back to the oil. The valve body flows back to the tank.

4. The introduction of software function

The advantages of the system:

(1) the whole system has no potentiometers and other adjustable devices.

(2) the system is all digital design with high accuracy, stability and safety.

(3) the system adopts digital zero adjustment and parameter calibration.

(4) the system control parameters can be automatically calibrated, and no system can be used after the technician has left.

(5) after the test, the system automatically analyzes the test data and curves, and can also be analyzed under manual intervention.

(6) special test reports can be customized according to customer requirements.

(7) system software integrates more than thirty national standards or test methods such as GB/T228-2002;

(8) the software is simple and easy to operate.

(9) the software can display the loading speed of the load;

(10) query, print and browse test data through the network.

5. Brief introduction of measurement and control software:

(1) introduction of MaxTest software:

Based on the WINDOWS operation platform, the software is simple and powerful, and has a human-machine conversation structure.

Four digit digital display test force value, accuracy for each gear range 20% starts to show the value of + 1%;

In four files, the digital display is deformed, and the accuracy is 20% for each gear range 20%.

At the same time, recording force time, deformation time, force deformation test curve, can switch observation at any time, random zoom down, horizontal or vertical movement, real-time high-speed sampling;

On the basis of automatic analysis, the results of elastic modulus, yield strength, tensile strength and so on are automatically calculated at the end of the test, and the accuracy of the analysis can be improved by manual analysis.

Test data is managed by standard database, and all test data and curves are automatically saved.

During test, the test curve is displayed in real time. After testing, the test data, curves and information of the test piece will be displayed in this operation window.

This set of control software has now integrated more than 100 national standards or test methods, so many national standards can meet the needs of customers' multifaceted test. The test report method can be customized and updated at any time according to the needs of the customer, which can bring great convenience to the customers.

The database can be Querying Historical test data, and only need to input certain conditions to find the test data immediately.

The force and deformation can be automatically calibrated. After we have completed the debugging, if the user is not allowed to feel the indication or the measurement parameters are changed, only click the automatic correction button, and the system parameters will be restored to the state of the debug.

Only use the mouse to operate on the two acquisition channels can be zero, the system is usually only once zero zero, in normal use, the system will automatically return to the real zero point;

A group of similar samples can be aggregated and analyzed, and the measured data can be compared and the average value can be calculated, so that the samples can be aggregated and printed in batches.

Provide a variety of report print formats, and users can edit any format reports according to needs (batch processing, control programmer, MaxDoc report processor, MaxXls report processor, etc.).

6 safety protection device

A) when the test force exceeds 3% of the maximum test force, the overload protection and the oil pump motor stop.

B) when the piston reaches the upper limit position, the stroke protection and the oil pump motor stop.

7 attachments

The complete set includes attachments, compression attachments, curved attachments.

8 other

Instructions for use, certificate of conformity and packing list are found in random technical documents.

Four. Quality assurance

After the formal acceptance of the equipment, the equipment shall be regarded as a formal delivery. The three period of the equipment is one year from the date of formal delivery (except for the other delay stipulated by the supplier). In the three package period, the supplier will service and repair all kinds of malfunctions of the equipment in time. During the operation of the warranty, the supplier will be in trouble with the ordering party and assist the ordering party to complete the maintenance task.

Five, after sale quality service

1. After the formal acceptance of the equipment, the equipment shall be regarded as a formal delivery. The three package period is one year from the date of formal delivery. The longest quality of individual parts is 3 years

2. Training

(1) our test crew arrives at the demand side, and our personnel arrive at the scene to debug. Free of charge for 1-2 operators of the demand side, the training place can be in the demand side company, or in our company.

(2) training must be carried out correctly using test machines, software operations and general maintenance and troubleshooting.

3. Maintenance service

(1) the consulting service provider will answer the questions on the phone or written in writing at any time.

(2) during the period of fault maintenance, the supplier will make a troubleshooting plan for the users within 24 hours and notify the users. If the supplier fails to solve the problem, the supplier will send someone to the service.

(3) only the maintenance cost is charged for the failure or damage caused by the natural person during the warranty period.

4. The following conditions are not in the scope of warranty

(1) failure or damage caused by abnormal operation and man-made or natural disasters.

(2) without our consent, we will demolished the damaged parts (such as microcomputer, mainframe, line, etc.).

(3) without our consent to install the virus software, arbitrary delete computer files or autolysis registration number can not work normally cause the test machine can not work.

5. Update service

(1) upgrade test software for users free of charge, and expand the experimental function for users.
