The titanium alloys in titanium alloy rods can be divided into three categories based on their phase composition: alpha alloys, (alpha+beta) alloys, and beta alloys, which are respectively represented by TA, TC, and TB in China. The caliper can be installed at the outlet of the forging machine, and the straightness can be installed behind the straightening machine.

The titanium rod manufacturer takes the detection of titanium rods with a diameter of 30-200mm as an example. For titanium rods with a diameter not greater than 50mm, a single probe is used for measurement, while for titanium rods with an outer diameter greater than 50-200mm, a dual probe is used for measurement. The transmitting lens and receiving lens of the dual probe are installed on a servo motor-driven linear guide slide, and the distance between the probes can be automatically adjusted according to the specifications of the titanium rod. The measurement accuracy remains unchanged after adjustment.

The caliper system mainly consists of a caliper and a control system. The control system includes a control cabinet, industrial computer, display, sound and light alarm, etc. Due to the high temperature of the titanium rod, additional components such as a high-pressure centrifugal fan and air filtration device are installed to cool the inside of the caliper by blowing air.

The caliper is installed at the outlet of the forging machine. When the titanium rod rotates and is pulled out of the forging machine, the caliper measures the outer diameter of the titanium rod. When the outer diameter of the titanium rod exceeds the set tolerance range, the sound and light alarm will automatically sound and light.

When the diameter of the titanium rod is not greater than 50mm, use a single measuring head in the middle position to measure the outer diameter of the titanium rod; When the diameter of the titanium rod is greater than 50mm, use adjustable spacing dual probes for measurement. As the diameter of the titanium rod forging decreases, it is necessary to adjust the spacing size of the measuring head.

The diameter measuring instrument can detect the diameter and straightness, and complete the size detection of titanium rods with a large span range through the combination of measuring heads, with high measurement accuracy.

In addition to diameter measurement, straightness measuring instruments can also be installed to online detect straightness dimensions and achieve high-quality production.
