In the fields of steel metallurgy, pressure vessels, shipbuilding, rail transportation, and engineering machinery, the impact resistance of metal materials at low temperatures is a key indicator for measuring their safety and reliability. From the preparation of sample notches to low-temperature constant temperature treatment, to the precise execution of impact testing, every step directly affects the accuracy of the test results. The fully automatic low-temperature impact testing system of Jinan Xinguang Testing Machine Manufacturing Co., Ltd. (hereinafter referred to as "Xinguang") covers three core equipment: fully automatic low-temperature impact testing machine, hydraulic lathe, and low-temperature tank, providing a full process solution from sample preparation to testing for low-temperature impact performance testing of metal materials.
1、 Fully automatic low-temperature impact testing machine: intelligent batch testing, achieving both efficiency and accuracy
The Xin Guang fully automatic low-temperature impact testing machine (JB-D300W series) is the core equipment of the entire system, used to measure the impact resistance of metal materials under dynamic loads. It is widely used in metallurgy, mechanical manufacturing, research institutes and other units.
Core technological advantages:
1. Fully automatic closed-loop control: using PC microcomputer control to achieve integrated operations such as electric swing, impact, measurement, calculation, screen display, and printing. After impacting the sample, the remaining energy can be used to automatically swing and prepare for the next test, especially suitable for laboratories with continuous batch testing.
2. Rapid automatic sample feeding: equipped with a dedicated sample feeding device for automatic feeding, automatic end face positioning of the sample, ensuring that the impact time from the sample being taken out of the furnace is not more than 2 seconds, fully meeting the requirements of the metal low-temperature Charpy impact test method.
3. Wide temperature range and precise temperature control: Adopting cascade compressor refrigeration technology, the low temperature range covers from 0 ℃ to -100 ℃, with a temperature control accuracy fluctuation of ± 1.5 ℃ and a gradient of 2 ℃, meeting diverse testing needs from room temperature to extreme low temperature.
4. Large capacity sample box: The sample box has a capacity of 20 and can load test samples in batches. With the automatic sample delivery system, it can achieve continuous unmanned testing.
5. Complies with the new national standard: This testing machine complies with the national standard GB/T3808-2018 "Inspection of Pendulum Impact Testing Machines" and conducts impact tests according to GB/T229-2020 "Charpy Pendulum Impact Test Method for Metallic Materials".
2、 Hydraulic lathe: dual blade dual station, complete precise notch preparation in 9 seconds
The quality of notch processing of impact specimens directly affects the accuracy of test results. The Xin Guang hydraulic lathe (UV-2Y series) is designed specifically for processing V-shaped and U-shaped notches on impact specimens. It is driven by hydraulic pressure and features high precision, high efficiency, and long service life.
Core technological advantages:
1. Dual blade dual station design: Adopting a liquid controlled dual blade structure, it can simultaneously process two sample notches: one V-shaped and one U-shaped notch, and can also process two V-shaped or two U-shaped notches at the same time without changing the blade, making the operation extremely simple.
2. Rapid processing: The sample notch can be processed in just 9 seconds, greatly improving the efficiency of sample preparation.
3. High precision notch forming: The processed V-shaped and U-shaped notches fully comply with the corresponding requirements of GB/T229-94 "Charpy notch impact test method for metals" and domestic and foreign standards such as ASTME23, ISO148, GB/T229.
4. High stability and good molding: Hydraulic drive ensures smooth operation of the puller, uniform cutting, and excellent consistency in notch size.
3、 Low temperature bath: efficient constant temperature cooling, ensuring precise low-temperature state of the sample
The low-temperature bath is a key pre-treatment equipment before impact testing, used for uniform cooling and constant temperature insulation of the sample. The Xin Guang DWC series low-temperature tank adopts imported compressor refrigeration technology, with high temperature control accuracy and simple and convenient operation.
The Xin Guang fully automatic low-temperature impact detection system fully complies with the following national standards and industry specifications:
-GB/T229-2020 "Charpy Pendulum Impact Test Method for Metallic Materials"
-GB/T3808-2018 "Inspection of Pendulum Impact Testing Machines"
-International standards such as ASTME23 and ISO148
The product is widely used in the following fields:
-Steel metallurgy: incoming inspection of steel, factory inspection of finished products, research and development of new products
-Pressure vessels: Low temperature impact toughness testing of container steel plates to ensure safe operation of equipment
-Shipbuilding: Low temperature toughness evaluation of marine steel
-Rail transit: Impact performance testing of key components such as wheels, axles, and rails
-Low temperature adaptability verification of steel used in construction machinery such as excavators and cranes
-Research Institute: Study on Low Temperature Mechanical Properties of New Materials and Processes
