When the mold 120 is brought into contact with one end of the pipe pipe 122 to force the mold 120 into the mold 120, the impact rollers 112 are rotated through the impact hole 118 during the rotation of the spindle 114. Since the swaging process of the pipe pipe 122 by the mold 120 is made by hitting the ()), the impact rollers 112 in the housing 110 during the rotation of the spindle 114 for the swaging process hit a plurality of When hitting the spheres (118) of course each of the molds (120) When the sliding pipe by the strong force and the tube pipe 112 generates a severe noise, it hinders the working environment and there is a risk of mass production of defective products due to the play of the related parts wear. Since frequent replacement is required due to rapid abrasion and damage caused by impact, there are many problems such as deterioration of work efficiency and increase in replacement cost burden of parts.

It is an object of the present invention to provide a swaging device for drawing pipes which can minimize the occurrence of noise during swaging and can extend the life by minimizing the wear and impact of related parts.

The swaging device of the present invention drawing pipe for achieving the above object is divided into several parts and once the part of the pipe pipe is inserted by the feeder into the molding chamber of the mold which can be connected to the supporting frame so that the mold outer surface and the inclined surface are inclined. It is characterized in that the sleeve was in contact with the hydraulic cylinder to operate to squeeze the mold to the swaging pipe tube.

According to the present invention, the mold 40 is in contact with the mold 40 through the guide inclined surfaces 54 and 58 in a state in which one end portion of the tube pipe 10 is coupled into the molding chamber 46 of the mold 40 divided into several parts. When the sleeve 42 is advanced by the hydraulic cylinder 44, the mold 40 is swollen and the swaging process is performed, thereby making it possible to improve the working environment because there is no fear of excessive noise during the swaging process. In addition, abrasion may occur due to sliding contact between the mold 40 and the sleeve 42 during work, but only when the wear occurs, only the difference in the coupling depth, there is no fear of malfunction and prevent excessive wear and damage of the related parts due to severe impact It can reduce the cost of repair and replacement of parts, and so on.
