Product introduction

JBDW-Y/D type microcomputer control automatic temperature impact testing machine is our company strictly in accordance with a new generation of high-tech products GB/T3808-2002 and GB/T229-2007 development, according to the JJG145-2007< verification regulation of pendulum type impact testing machine on the factory inspection, the impact testing machine for microcomputer control automatic low temperature impact test machine, used to test the impact resistance properties of metal materials under dynamic loads, detection equipment metallurgical machinery manufacturing and other units of the necessary, the test equipment is indispensable for the research of new materials research units. This machine is the pendulum type impact test, using PC microcomputer PLC controller, high reliability, electric pendulum movement and feeding, positioning, shock, temperature control temperature control are electrical instrumentation control, automatic feeding equipped with special feeding device, automatic sample positioning section, sample released to impact time less than 5 seconds, fully meet the GB/ T229-2007< metal in summer The low temperature impact test device for test method for notch impact ", the equipment of low temperature device adopts cascade compressor refrigeration technology, using the principle of heat balance and circulation agitation method to achieve automatic uniform cooling, the sample temperature, the temperature control indicator can fully meet the requirements of the national standard GB/ T229-2007. Computer measurement test data operation, screen display results, can calculate and display the material impact absorbing energy, impact toughness, pendulum angle and lifting test average, average print test report containing when test data and test values. The testing machine for the automatic feeding of high working efficiency, high test precision, the residual energy in impact specimen automatic pendulum movement and prepare the next impact test in laboratory continuous impact tests and lots of impact tests of metallurgy, machinery manufacturing and other departments can better reflect its superiority。

◆ Significant advantages of software and operating systems

1. computer screen display, dial shows at the same time, data synchronization, equipped with dual operation system can through the operation of the computer mouse, also available controller button operation, do not interfere with each other, flexible operation, to avoid the due to electrical fault can not be used, the working efficiency is high.

2.  for continuous test, artificial operation just as by placing the specimen and press the action button, all the rest of the work is testing machine for automatic completion of, reduce labor intensity, the complete elimination of artificial data recording error probability, especially suitable for large amount of test of metallurgical mining industry to use.

3. select special functions abundant swing hammer impact testing software can automatically record the test results to the database for storing and searching operations. Software is running in the Win7, consistent user interface with windows style Chinese Windows system. Arranging and the fetching, return pin, shock, put test operation are can be completed on the computer screen to input or mouse click.

◆ Significant advantages of electrical control section

1. to import the PLC controller as the core of the electrical control system, using high precision photoelectric encoder as the angle acquisition sensor.

2. integrated circuit board, maintenance is more simple.

3. using the brush clutch to replace the old clutch, the test, the pendulum automatic take place, the clutch is effectively protected, reduce the system to the clutch tooth damage, prolong the system life.

◆ Significant advantages of mechanical parts

1. the advanced host structure technology design, the host base and column using a new design and packaging, beautiful appearance, solid and durable, reasonable structure.

2. the high rigidity of the pendulum rod to prevent the pendulum impact after the shaking of the sample.

3. the use of standard turbine reducer, high efficiency, completely avoid the transmission failure.

4. modular structure, reducing the processing and assembly process, the host accuracy is greatly improved.

5. using the photoelectric proximity switch instead of the old-fashioned mechanical limit switch, improve the stability of the equipment, the angle of the pre - lift is constant.

◆ Significant advantages of security

Use of high toughness materials semi closed door cover contains the pendulum the orbit, and also prevent being washed off the sample spatter wounding, maximize avoid misoperation brought to the operating personnel injury, ensure safety.

◆ Feeding mechanism: specimen in cryogenic cooling to the set temperature, mechanical feeding material mechanism can be quickly and reliably the specimen was sent to the anvil bearing surface. Feeding mechanism mainly by the motor, controller is composed of two parts. Mechanical feeding movement of the feeding mechanism is signals sent by the electrical motor control to achieve rail forward and backward to complete the automatic feed material of action。
◆Positioning mechanism: the sample must be close to the side of the anvil, the specimen correctly at the center. The pendulum blade is ensured by the positioning mechanism. The sample consists of a feeding rod to the front seat, because the feeding guide function, make the specimen close to the side of the forward movement of the anvil, the anvil after entering the front face, the magnetic switch feeding mechanism of signal, then positioning mechanism, positioning mechanism of rod to the working position, positioning mechanism side elastic top column pressed sample, complete the sample location. When the feeding rod to the front end, the magnetic switch signal, the electric machine won after the signal reset, away from the specimen positioning mechanism the positioning surface for impact. A positioning mechanism and a bracket integrally, reset pull and motor drive spring positioning block before and after the move, push the positioning screw under the action of the spring, the positioning column is always close to the fixed position, at the same time by adjusting The whole positioning block, improve the accuracy of the positioning of the sample.
