Dab tsi yog hlau stamping qhov chaw?
The hardness test of metal stamping parts adopts Rockwell hardness tester. Small stamping parts with complex shapes can be used to test the plane is very small, can not be tested on the ordinary desktop Rockwell hardness tester. The PHP series portable surface Rockwell hardness tester is very suitable for testing the hardness of these stamping parts. Alloy stamping parts are the most commonly used parts in metal processing and mechanical manufacturing. Stamping processing is a processing method that uses molds to separate or shape metal strips. Its application range is very broad.
Stamping processing includes punching, bending, deep drawing, forming, finishing and other processes. The materials processed by stamping parts are mainly hot-rolled or cold-rolled (mainly cold-rolled) sheet metal materials, such as carbon steel plate, alloy steel plate, spring steel plate, galvanized plate, tin plate, stainless steel plate, copper and copper alloy Plate, aluminum and aluminum alloy plate, etc.
1. Kev ntsuas hardness ntawm cov khoom siv stamping
Lub hom phiaj tseem ceeb ntawm kev sim hardness ntawm stamping qhov chaw yog los txiav txim seb lub annealing degree ntawm cov ntawv hlau yuav khoom yog tsim nyog rau cov tom ntej stamping qhov chaw ua. Cov txheej txheem sib txawv ntawm stamping qhov chaw ua cov txheej txheem xav tau cov phaj sib txawv ntawm qib hardness. Aluminium alloy phaj siv rau stamping qhov chaw tuaj yeem kuaj nrog Webster hardness tester. Thaum cov khoom thickness ntau dua 13 hli, Barcol hardness tester tuaj yeem siv. Cov ntshiab txhuas phaj los yog tsawg hardness aluminium alloy phaj yuav tsum siv Barcol hardness tester.
2. Hardness kuaj ntawm stamping tuag
Cov khoom tseem ceeb ntawm stamping tuag yog hlau tuag (xws li cov cuab yeej steel thiab siab -ceev steel), thiab qee zaum cemented carbide yog siv.
Stamping tuag feem ntau yuav tsum muaj siab hardness thiab hnav tsis kam, kev kho cua sov yog qhov tseem ceeb.
