Problems solved by technology
After loosening the jaws, the plug is difficult to pull out due to the deformation of the steel pipe during clamping
Usually, a sledgehammer is used to hit the steel pipe at the plug position or a long steel rod is extended from the other end of the steel pipe to knock the plug out. This process needs to be repeated every time a steel pipe is drawn, which is labor-intensive and low in production efficiency. Striking the finished steel pipe will affect the quality of the steel pipe

The invention discloses an automatic loading and unloading type plugging tool for cold-drawn steel pipes. The automatic loading and unloading type plugging tool comprises a jaw flange, a jaw flange slider, a jaw, a plug and a baffle, wherein the jaw flange slider is connected with the jaw through screws, the jaw flange slider is located in a sliding groove formed in the jaw flange and can make opening and closing motion, one end of the plug is connected with the center of the jaw flange, and the baffle is arranged at the outer side of the plug and arranged in the jaw. During use, the plug can back with the jaw flange and withdraw from an inner hole of a drawn steel pipe. Through the application of the automatic loading and unloading type plugging tool, the work efficiency is increased, and the labor intensity is reduced.
Description
【Technical field】 [0001] The invention relates to the technical field of steel pipe production equipment, in particular to an automatic loading and unloading plug tooling for cold-drawn steel pipes. 【Background technique】 [0002] In the traditional cold-drawn steel pipe loading and unloading plug tooling, in order to facilitate the pulling out of the steel pipe to be drawn from the mold, the plug is generally placed inside one end of the steel pipe to be drawn by hand, and then the plug is clamped with jaws. Pull out the steel pipe at the head position. After the jaws are loosened, the plug is difficult to pull out due to the deformation of the steel pipe during clamping. Usually, a sledgehammer is used to hit the steel pipe at the plug position or a long steel rod is extended from the other end of the steel pipe to knock the plug out. This process needs to be repeated every time a steel pipe is drawn, which is labor-intensive and low in production efficiency. Striking an...
