Testing machine tensile machine accessories: dotting machine gauge

The gauge distance gauge (also called dotting machine) produced by Jinan Jinli Testing Instrument Co., Ltd. (Jinan Jinli Testing Machine Factory) is designed and manufactured in accordance with the requirements of the national standard metal material tensile test. This equipment marks the marking The distance is accurate, the work efficiency is high, and the operation is simple and easy to master. It is a supporting instrument that should be prepared in the laboratory.
Main technical parameters
Long gauge length
Shape size (length, width and height)
Heavy duty
Operating principle
The equipment passes through a spiral belt The shaft rotates, the punch is lifted sequentially at different angles, and the punch is struck sequentially with the help of the elastic force of the spring. Shake the handle for one turn to produce an accurate sample with a straight line spacing of or and a total length on the sample blank.
Operation method
Place the equipment on a workbench about a height above the ground, place the sample in the groove of the equipment, and determine the left and right positions of the sample
According to the diameter of the sample size, adjust the nuts at the lower ends of the two columns to maintain a suitable distance between the tip of the punch and the sample
Press the curved part of the upper curved handle with your left hand to compress the sample, and then shake the right handle with your right hand for a week to punch out the gauge point
br/> Lift up the bending handle and take out the sample to complete the gauge length work
