The operation steps of GBC-60W microcomputer controlled cupping punching cup testing machine for cupping test
The operation steps of GBC-60W microcomputer controlled cupping punching cup testing machine for cupping test:
The high-quality GBC-60W microcomputer-controlled cupping cup punching test machine developed and manufactured can not only complete the cup punching test of the material, but also complete the cupping test and the ear-making rate test of the material.
When performing cupping test, according to GB/T 4156-2007 'Metallic material sheet and thin strip Erickson cupping testIt can be ribbon or square.
Warm reminder of the testing machine: When cutting the sample, the sample must be kept flat, its edges must not be twisted by burrs, and the sample must not be hammered or cold or hot processed. The sample cut on the coil should be The test is carried out without straightening.
GBC-60W microcomputer controlled cup punching cup testing machine Before the test, both sides of the sample and the punch should be lightly coated with graphite grease or other types of grease. Turn on the computer and click the test software icon to enter the software; turn on the power of the host, press the power;, oil pump; button, the oil pump starts; click on the host operating panel to clamp; release; button to view the clamping and loosening of the cushion mold Whether the opening is normal; select the displacement speed 5mm/min; on the software interface, and then click the up; button, observe the displacement window, if the value increases, it is normal, click the stop; button.
Put the sample between the cushion mold and the pressing film, and then turn the button switch on the main operation panel of the cupping punching cup testing machine to the clamping position; clamp the sample;
Click the New; button on the software operation interface, enter the relevant sample information, and click the Start; button to start the test;
The rupture of the sample can be judged from the decrease of the force value. Generally speaking, the softer and more uniform the material state, the rounder the cracks, while the cracks of hard materials tend to be straight and often accompanied by cracking sound.
The cupping test mainly records the cupping value, but the maximum pressing force, clamping force and crack shape also have a certain reference value for judging the strength state and uniformity of the material. For the detailed requirements of the test, please refer to GB/T 4156 'Erickson Cupping Test of Sheets and Strips of Metallic Materials'.
If you encounter any problems during use, you can contact your after-sales service engineer or business manager at any time.
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.
