A piercing machine for producing thermocouple protective sheath

Abstract

The application relates to a piercing machine for producing thermocouple protective sleeves, and relates to the field of piercing machines, which includes a machine body and a fixing assembly for fixing a metal rod. The fixing assembly includes a fixing seat, a clamping plate and a driving cylinder, and the clamping There are two plates and they are respectively arranged on both sides of the fixing seat along the length direction of the metal rod. The clamping plate is provided with a placement groove for placing the metal rod. The placement groove is located on the side where the two clamping plates are close to each other. There are multiple sets, and they are arranged symmetrically on the side where the two clamping plates are far away from each other. The driving cylinder is fixed to the fixed seat, the piston rod of the driving cylinder is fixedly connected with the clamping plate, and the driving direction of the piston rod of the driving cylinder is the direction of the clamping plate. In the direction of approaching or moving away from each other, the fixing base is provided with a detection piece for detecting whether the metal rod is placed horizontally. The application has the effect of making the metal rod more stable during the drilling process, thereby improving the production efficiency of the thermocouple protective sleeve.

Description

Technical field [0001] The present application relates to the field of perforating machine, in particular to a punching machine for the production of a thermocouple protective sleeve. Background [0002] Thermocouple is a common temperature measuring element in temperature measuring instruments, which can directly measure temperature and convert the temperature signal into a thermoelectromotive force signal, and convert it into the temperature of the measured medium through an electrical instrument. [0003] In the production process of galvanizing pots, it is necessary to add a thermocouple to the galvanized pot, and because the thermocouple cannot be directly exposed to the zinc-containing solution, it is necessary to set a protective sleeve on the outside of the thermocouple. In the production process of the protective sleeve, due to the long length of the thermocouple itself, it is usually the use of a fixture to fix the metal long rod for reference Figure 1 , the fixture inc...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that due to the long length of the thermocouple, when the metal rod is clamped by the clamp, the metal rod may shake, so that the punching machine cannot complete the drilling at one time. The long rod is drilled multiple times to ensure that the holes used to place the thermocouple are more uniform, which makes the drilling process of the metal rod more troublesome for the piercer, and the production efficiency of the thermocouple protection sleeve is low.
