What is the working principle of the impact testing machine?
Impact testing machine (English name: impact testing machine) refers to a material testing machine that applies an impact test force to a sample and conducts an impact test. Impact testing machines are divided into manual pendulum impact testing machines, semi-automatic impact testing machines, digital display impact testing machines, microcomputer controlled impact testing machines, falling weight impact testing machines and non-metallic impact testing machines. By replacing the pendulum and the sample base, two types of tests of simply supported beam and cantilever beam can be realized. Pendulum impact testing machine is a kind of impact testing machine. It is a tester used to measure the resistance of metal materials to impact under dynamic load, so as to judge the quality of materials under dynamic load. The drop-weight impact testing machine is another type of impact testing machine, which is suitable for the drop-weight impact test of ferritic steel (especially various pipeline steels). The impact tester is divided into manual pendulum impact testing machine, semi-automatic impact testing machine, non-metallic impact testing machine, digital semi-automatic impact testing machine, and computer-controlled impact testing machine at the moment of impact by the hammer. The digital display automatic impact testing machine generates signals through high-speed load measurement sensors, amplified by high-speed amplifiers, and quickly converted from A/D to digital signals and sent to the computer for data processing. At the same time, the angular displacement signals are detected and sent to the computer for data processing. High accuracy. Equipped with high-speed angular displacement monitoring system and force detection sensor and amplifier, through computer high-speed sampling, data processing, can display NT and JT curves, data storage, data report printing, etc., can instantaneously measure and record the characteristics of the material in the process of impact Curve, by replacing the pendulum and the sample base, two types of tests of simply supported beam and cantilever beam can be realized.

Hydraulic universal testing machines have very high accuracy requirements.
The hydraulic system is the power drive mechanism of the tensile testing machine.
The specific application of the electronic universal testing machine in the automobile manufacturing process: The electronic universal testing machine needs to be used for automobile parts.
Wave soldering refers to the molten solder (lead-tin alloy), sprayed by electric pump or electromagnetic pump into the solder wave required by the design, can also be formed by injecting nitrogen into the solder pool, so that it is pre-loaded The printed board of the component realizes the soft soldering of the mechanical and electrical connection between the solder end or the pin of the component and the pad of the printed board through the solder wave.
The frequency converter is a power control equipment that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply.
Electronic universal testing machine is a necessary equipment to control the quality of products.
The calibration operation of the electronic universal testing machine is still relatively unfamiliar to friends who use it for the first time.
Selective wave soldering defects and their prevention.
Testing machine, broadly speaking, is an instrument that verifies the quality or performance of a product or material according to the design requirements before it is put into use.
The tensile force is not an accurate value after being measured by the testing machine, and subsequent calculations are required to get the desired value.
