Introduction: The GBW-50 microcomputer controlled cupping tester has a novel design and generous appearance. It conforms to ergonomics. It is a precision equipment for performing technical performance tests on thin metal sheets and strips. It can realize GB/T4156-2007 "Thin metal sheets and thin materials. With the Eriksson Cupping Test Method” to meet the requirements of JJG 583-2010, JB/T7408-94; GBW-50 Microcomputer Controlled Cupping Test Machine also adopts the standard of ASTM E643-2008 to inspect the metal sheet and strip Plastic deformation properties during the test. Features: 1. The GBW-50 microcomputer controlled cupping test machine adopts a new structural principle. It is used for constant speed loading of servo motor and can realize constant rate control. The computer can control the stamping process. The stamping speed can be steplessly adjusted and preset. (In the past, the cylinder oil source could not achieve constant rate control after power supply.) 2. The clamping force is independently loaded by the hydraulic oil source, the clamping force can be adjusted, the data can be displayed synchronously, and can be independently calibrated. 3, the force measuring device has been changed in the past hydraulic sensor for the spoke sensor, cupping value measurement for the encoder measurement, the punch movement during the test using our company's first low-friction mobile device, combined with high-precision wheel sensor (direct force measurement ) Tests for ultra-thin sheets (0.05 to 3 mm) are possible, while the accuracy and reliability of cupping measurements by the tester are greatly improved. The perfect match between the measuring device and the loading device and its control program of the instrument solves the problem of poor repeatability of the previous test data, and also provides a reliable basis for the implementation of the new cupping machine calibration verification protocol and cupping test method in China. . 4. Convenient replacement of cup-shaped molds, easy loading and unloading of the samples, pressing the automatic button after the sample is placed, the test parameters can be input and changed, the closed-loop control can be realized in the stamping process, and the sample can be cracked when the value of the pressing pressure drops. Automatic parking, while easy to observe the sample cracks. The test data computer shows that it has a peak memory function, that is, the maximum punching pressure, cupping value, etc., to achieve the report of the test results, storage, batch, curve drawing, etc., deformation height automatic memory, a test can be automatically restored to be tested status. Technical Parameters: Maximum test thickness: Standard cupping test 0.05 ~ 3mm (high-precision sensor, ultra-thin plate test can be achieved) Maximum width of sheet: 90-100mm Punch maximum stroke: 60mm Maximum cup load: 50kNmax; (According to the punching pressure of the customer's material, configure the maximum punching load) Maximum clamping load: 10kN Cupping resolution: 0.01mm Test force measurement accuracy: ±1% Deformation accuracy: ±0.5% Test speed: 0.05mm/min-200mm/min (stepless speed regulation) Cupping test mold specification: Standard punch ball: φ20±0.05mm Standard mat die hole diameter: φ33±0.1mm Standard fixed die hole diameter: φ27±0.05mm Computer display content: clamping load, punching pressure, displacement and cupping value, rate, test curve, etc. Control method: Computer automatically implements the test process Hydraulic oil: N46 hydraulic oil (generally available at gas stations) Dimensions: 780×780×1100(mm) Power Supply: AC380V, AC220V Weight: 260Kg
