The round tube after the angle is placed in the stamping die to punch the ball plug semi-finished product, and then a round tube with a diameter matching the size of the bottom opening is placed above the item opening of the ball plug semi-finished product, and the upper and lower end edges of the tube are inclined from the inside to the outside. The lead angle makes the bottom edge of the round tube exactly in line with the exit edge of the semi-finished product of the plug after it is inserted; The plug center has a continuous circulation ring, and the water supply flow can be smoothly flowed without forming a turbulent situation; and because the ball plug is manufactured and formed, there is no need to weld, and the roundness and continuity of the manufacturing process make the manufacturing process simple. 'And can speed up producer catch. According to the customary method of manufacturing the ordinary ball plug, please refer to the application No. 85219580 "Improved structure of the ball plug", which is mainly punching two flat metal plates into two by a die. The shape of the upper and lower hemispheres is symmetrical, and the two hemisphere shells are welded together to form a spherical shell. Then, a tube with a proper length and outer diameter is inserted into the spherical body. 'And apply welding to join to form the rough winner of the ball plug; finally' After roundness correction and surface polishing, to complete a ball plug structure;-Although this ball plug manufacturing method can reach all The function requirements of the ball plug, however, because the ball plug must be connected by the ball shell, and the two hemisphere shell must be; the special processing steps in the over punch and edge trimming, and because of the two hemisphere-like body The edges must also be processed for true roundness and surface polishing, so that the two hemisphere shells can accurately synthesize a spherical shell with true roundness, which complicates the entire manufacturing process and increases processing difficulty. 2 Chinese National Standard (CNS) Λ4 is now available (2〗 OX29 ·?

Description of the invention. ) In order to overcome the above-mentioned shortcomings of Ke Yuegen, the industry has developed a method for manufacturing hollow ball plugs. 'Please refer to the application method of plunger plowing for making application No. 87121847. As shown in the first figure, it mainly takes a diameter The specifications can be matched with the circular pipe village of the die, and then the pipe is placed in the die. Among them, the die is provided with a die slot at the center of the upper and lower die, and a module is provided in the center of the die slot. The hydraulic punch presses the die force σ for the round tube to follow the arc spherical surface of the die groove to change the degree to form a ball plug. However, although this manufacturing method can meet the functional requirements of ordinary ball plugs, After the round tube is squeezed by strong force, its end edge will be locked at the sharp corner of the die groove and the punch due to the pressure, which will make it difficult to remove the formed ball plug. Even when the pinch is too tight, it must be beaten. Way to loosen the tightness of the part where the dust is squeezed in. Causing damage to the surface of the ball plug, causing uneven water flow at the surface of the ball plug leakage. Furthermore, due to the traditional Fan, the ball plug is an internal hollow ball-shaped valve body, so that the water flowing from the water hole of the faucet into the Fan plug will collide with the wall of the ball and form a bubble in the tube, causing a liquid. Unsmooth outflow and formation of turbulence. In view of the fact that the customary manufacturing method and the actual burial end of the finished product are actively researched and developed, the inventor has successfully developed a number of trials and amendments during the period, and finally successfully developed a variety of deficiencies that can be completely eliminated. , And can greatly enhance its effectiveness, and more economic value. The main purpose of the present invention is to provide a universal ball plug manufacturing method for forming pipe fittings. Firstly, take a moderately shaped piping tube, and tilt the leading angle from the outside to the inside of the upper and lower ends of the pipe in advance.
