Description

{Welding pipe inner bead removal device}

The present invention relates to a metal bead pipe inner bead removing apparatus, and more particularly, to a metal bead pipe inner bead pipe removing apparatus which removes weld beads generated in an inner weld portion of a pipe by forming a plate- And to provide a cooling device for efficiently cooling the welding bead in the process of removing the welding bead.

Generally, a molded metal pipe is manufactured by forming a pipe base material on a strip into an annular shape by a forming roller and welding the formed pipe base material by a high frequency induction heating method.

A weld bead is formed on the inner surface and the outer surface of the welded portion of the metal pipe. The weld bead formed on the inner surface of the pipe is removed using a bead removing device having a bite.

Most conventional metal pipe inner bead removing apparatus employs a roller means for smoothly proceeding the metal pipe and has a method of removing the bead by the relative cutting force by the progress of the pipe by using the bite mounted on the bite holder.

In addition, the bead removing device has a cooling structure that supplies cooling water to prevent the load from being applied to the inflator rod by high-temperature welding heat.

However, in the conventional metal pipe inner bead removing apparatus, there is a problem that the support is provided with the bite holder equipped with the bite, the roller means is provided, and the impeller composed of the core and the core case are integrally formed and overload is imposed on the impeller during operation.

In addition, conventionally, there is a problem that the welding heat of high temperature is directly applied to the impellers near the center of the welding roll, and the welding is overloaded.

Also, conventionally, the conventional bite for removing the weld bead has a disadvantage in that one byte can not be used for a long time because the cutting edge is formed at only one of the upper and lower sides and can not be used for both sides.

In addition, conventionally, there has been a problem that the cooling water supplied to the impeller flows out to the outside and the workplace becomes very dirty.

Korea Patent No. 0682318 has been registered. Registered utility model 0308445 registered in Korea has been registered. Registered utility model 0198990 registered in Korea has been registered.

In order to achieve the above object, the present invention provides a beverage dispenser comprising first, second, and third bead removing means for removing beads formed on the inner surface of a metal pipe, a support having a plurality of rollers mounted thereon, And a plurality of cooling water passages formed at both ends of the core, wherein the cooling water passages are formed in the guide passages, An oil injection nozzle for injecting cutting oil into the bite provided in the bead removing means is installed in the groove, and the oil injection nozzle is installed in the groove, An oil supply pipe for supplying a cutting oil to the oil injection nozzle, a cooling water supply pipe for supplying cooling water, The cooling water discharge pipe to the pipe inner surface weld metal bead removal device which is characterized in that the through-connection to discharge the cooling water.

According to the present invention having the above-described technical structure, not only the above-mentioned bite can be used as both the upper and lower sides, but also the cutting oil is injected into the bite, thereby increasing the life of the bite.

In addition, the high temperature welding heat is prevented from being directly applied to the inferders close to the center of the welding roll, thereby preventing a load from being applied.

By supplying and discharging the cooling water in a circulating manner, it is possible to prevent water from being generated inside the metal pipe to be oxidized and, at the same time, the cooling water can be prevented from flowing out to the outside.
