产品简介

The screw torsion test machine mainly tests the torque test and torsional torque value of screw screw, screw, screw column and other products. It can also be used to test the torsion mechanical properties of metal materials and finished products at room temperature, and can also be used in the torsion failure test of materials and finished products.

执行标准

GB/T3098.1-2010 "mechanical properties of fasteners bolts, screws and studs"

GB/T3098.13-1996 torque test and destructive torque of bolts and screws for mechanical properties of fasteners

GB/T10128-2007 "test method for torsion of metal at room temperature"

JJG269-2006 "verification regulation of torsion test machine"

JB/T9370-1999 "technical conditions for torsion test machine"

JJG762-1999 "verification regulation of extensometer"

GB/T2611-2007 "general technical requirements for testing machines"


功能特点

The mainframe adopts the horizontal structure, the main body structure adopts the whole thickening steel plate structure to ensure the rigidity of the whole machine. The fixture is quenched with high quality carbon steel 45 (HR55 ~ 65) and has a long life, and the installation and disassembly of the sample are convenient and quick.

Drive system] all digital Testmart control system drive, adjustable speed adjustment, uniform load and stability.

Transmission system] the digital display material torsion testing machine adopts the precision decelerator drive to ensure the transmission uniformity, stability and transmission accuracy. The transverse space is arbitrarily adjusted within the range of 0 to 500mm.

[measurement and display system] the machine uses large screen LCD display system to synchronously display the torque T, torsion angle theta and test speed of the sample. The system can set torsion angle theta, check the torque of the test piece, or set the torsion angle of the torque test specimen.

[safety protection system] digital display material torsion testing machine is equipped with overload protection and over current protection.
