Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for filling a flux in a manufacturing process of a welding flux shear wire, and more specifically, it relates to a method for filling a welded pipe, seamless wire, or other steel pipe into a coiled wrapping body. This invention relates to a method for filling flux into a steel pipe by applying vibration.

Flux for welding A method for filling the inside of a wire with flux in the process of manufacturing a seamed wire with welded seams or a seamless wire without a seam will be explained with reference to FIG. In the figure, P is a steel pipe wound around a steel bobbin 1, 2 is a vibration table equipped with a vibration motor for applying vibration to the pipe via the bobbin 1, and 6 is a hopper for storing welding flux F, which is a vibration nozzle 8. , is provided with a weir 9 for preventing segregation. The pipe P wound around the bobbin is placed on the vibration table 2 so that the axis of the wound body is vertical, and the 7 lux supply end of the pipe P is bent upward beyond the upper flange of the bobbin 1. It is connected to a funnel 5 which receives flux from a hopper 3 via an electromagnetic feeder 6 via an intermediate pipe 4, and a lid 7 for preventing flux leakage is provided at the end of the pipe P. Conventionally, with such a configuration, 7 lux F was supplied and filled into the pipe P by vibrating the wrapping of the pipe P, but this method had the following problems. ■The end of the pipe P wound around the bobbin 1 is covered with a lid 7, so the pipe P
The air inside is discharged through an intermediate pipe 4 for supplying slacks. Therefore, the supply of 7 lux through the intermediate pipe 4 must be adjusted little by little so as not to interfere with the discharge of air through the same pipe, so that the filling time is short. For the same reasons as ① and ②, it is difficult to supply flux uniformly, and there may be uneven filling of flux, that is, the flux is not evenly filled in the longitudinal direction of the pipe, and it is difficult to fill the flux densely, so it is difficult to supply flux uniformly. It is difficult to fill the filling weight. (2) The filling amount of flux at the end of the pipe P tends to be more dense than other parts, and since this part is cut off and discarded, it causes a decrease in yield.

(2) Pipes filled with syflux by the conventional method have uneven filling in the longitudinal direction of the pipe, which causes wire breakage in the next wire drawing process. Moreover, the quality of the product wire was degraded.

The present invention has been made in order to solve the problems of the above-mentioned conventional method, and it is possible to supply and fill a coiled steel pipe with 7 lacs in a short time, and there is no uneven filling. This method provides a filling method that can uniformly fill a predetermined amount of flux into a pipe.The gist of this method is to place a steel pipe wrapping on a vibration table, apply vibrations, and shake the ends of the steel pipe. When supplying and filling flux from the steel pipe wrapping, a starting end pipe equipped with a branch pipe for air release is connected to the 7 lux supply side end of the steel pipe wrapping, and an open end is connected to the terminal end of the steel pipe wrapping. The purpose is to connect an upwardly directed end pipe and supply and fill the steel pipe wrapping with welding flux through the start end pipe. In a more preferred embodiment, 7 lux is filled into the pipes with both the starting end pipe and the ending pipe partially wrapped around a steel pipe wrapping.

The present invention will be explained below with reference to embodiments shown in the drawings.

FIG. 2 is an overall side view of an apparatus for supplying welding flux to a wound body of steel pipe P wound around a bobbin 1, and the same parts as in FIG. 1 are given the same numbers. Steel pipe P
The winding body is mounted on the vibration table so as to receive the vibrations of the vibration motor reliably by fixing the outer peripheral edge of the lower 7 flange of the bobbin and the shaft hole with the fixing jig 17 and the protrusion 17' of the vibration table 2, respectively. It is placed and fixed on. A pair of vibrating motors 12 and 12'(12' not shown) are integrally installed on a vibrating table at an angle of approximately 60° from the vertical line, and a winding body, that is, a pipe, is attached to the vibrating table. Vibrations centered around the central axis of the wrapping body are applied to the winding body. And the vibration table 2 is the spring 1
By being attached to the pedestal 18 via the vibration table 6, the vibrations of the vibration table are not transmitted to the pedestal 18. In this way, the winding body was placed on the vibration table with its central axis aligned with the imaging center of the vibration table, and 7 lux was supplied from the pipe end above the winding body by vibration. Flux is guided to the other lower end, and as shown in the figure, the flux supply side pipe end of this winding body has a start end pipe 1o equipped with a branch pipe 10' for air bleeding, and the end end has a start end pipe 1o equipped with a branch pipe 10' for air bleeding. Terminal pipes 11 with their open ends facing upward are connected to each other. Terminal pipe 10 connected to both ends of this pipe P
．． A flexible transparent pipe 11 is used so that the moving state of the flux can be seen. The starting end pipe is further connected to the funnel 5 which receives 7 lux from the flux hopper 6 via the electromagnetic feeder 6, so that the welding flux is transferred from the hopper 6 to the electromagnetic feeder 6 to the funnel 5 to the starting end vibrator 10.
→ The starting end of the pipe P in the winding body → The terminal end of the pipe P → The terminal pipe and the winding body move due to vibrations, and after a predetermined time, the entire pipe winding body is tightly filled and the movement of flux stops, and the supply and filling are stopped. ·finish.

When replenishing flux into hopper 6, use funnel 5.
Remove the starting end pipe 10 from the holder, rotate the hopper frame 16' approximately 90 times around the shaft 16 by pressing the button on the operation panel 14, operate the lifting motor 15, and move the support base 19 to the column 19.
', and the flux is replenished into the hopper 6 at the lower position.

In the present invention, as described above, flux is supplied into the steel pipe P through the start end pipe having branch pipes, so the air in the pipe P is replaced with flux and discharged to the outside through the branch pipes, and further winding is performed. Since a terminal pipe is connected to the terminal end of the pipe P, the water is also discharged to the outside through the terminal pipe. The terminal pipe has a 7-lux outflow prevention mechanism in addition to such an air discharge mechanism, and the supplied slack passes through the terminal end of the pipe P and rises to the middle of the terminal pipe bent upward,
It doesn't rise any further. Therefore, the flux is tightly packed throughout the pipe wrapping without leaking to the outside. As a result, the time required to fill the flux into the shivive wrapping body is reduced to half of the conventional one, making it possible to fill the flux evenly and uniformly. Furthermore, dense packing can be achieved quickly, so filling can be done according to the target filling rate. The advantages are great, such as the possibility of

FIG. 6 is a diagram showing another embodiment, and in this example, the starting end pipe connected to the starting end and the ending end of the pipe wrapping body,
A part of the terminal pipe is wound around a wrapping body and connected to the end of the pipe P.

That is, the starting end pipe 2o, whose both ends are connected to the pipe wrapping body and the funnel 5, is connected to the starting end of the pipe P by winding a part 20' around the winding body, and is connected to the bobbin 1 with the open end facing upward. The terminal pipe attached to is part 2 of
1' is wound around a wrapping body and connected to the terminal end of the pipe P. This is because the pipe part at the beginning and end of the winding body tends to have a horizontal light unevenness of 7 lux compared to other pipe parts, so this filling unevenness is caused in the vibrator at both ends. It is designed to maintain a good state of flux filling in the steel pipe portion of the wrapping body. This results in an even better 7 lux filled steel pipe. Note that 20 is a branch pipe.
