TW455657B - Improved manufacture of valve ball plug - Google Patents

Abstract

Disclosed is an improved manufacture of valve ball plug, comprising the steps of: using a tube as the material; using a plurality of rolling mold wheel sets for sequentially and gradually pushing and rolling, or using a plurality of aligned pressing mold sets to intermittently and gradually pressing the intermittently rolling tubes to form the spherical configuration of the ball plug; such that the rolled or pressed tubes are formed into a series of connected ball plug blanks; using a cutter of an automatic lathe to trim each of the connected ball plugs off after the ball plugs are formed and depart from the rolling mold wheel sets or the pressing mold sets, so as to quickly form the ball plugs, reduce defective rates, and reduce manufacturing cost.

Description

4 5 5 65 7 V. Description of the invention (ι) The present invention relates to the improvement of a common ball plug as a material, using a number of side-by-side 辘 懕 tan 蚣 β y especially for pipe fittings, Sui Shi # Anπ I according to its The ball-shaped arc of the ball plug breaks: it is formed by rolling; or a stamping die is used to continuously punch the "· 俾" into a series of interconnected ball plugs. The borrow is then borrowed: the lathe of the automatic lathe is then truncated. Each plug is connected to achieve rapid ball plug formation, and can reduce the defect rate and processing cost = the common ball plug in the case, using the latest manufacturing method to apply pipe 7 to borrow the upper and lower half ball molds' And the direct punching of the pipe fittings into a ί ί ί ϊ ϊ ϊ ϊ ϊ ϊ the forming method is because of the axial punching of the piping, does the uncertainty of the ϊ shape f often make the rigid ball plug impossible? The ideal that should be achieved is that the arc inside the mold changes to y, which causes a high failure rate and an increase in cost. Each time a ball plug is formed, it must be manually removed, and then the pipe is installed on the mold. The replacement action has a limited manufacturing speed, and its relative danger cannot be ignored. For this reason, the inventors have actively researched and developed design in view of the actual disadvantages of the traditional manufacturing method and the finished product. After several trials and corrections during the period, they have successfully developed a variety of people who can completely remove the traditional practice. Missing. The main purpose of the present invention is to provide an improved method for manufacturing a universal ball plug, which uses pipe fittings as a material, and uses several sets of rolling die wheels to roll and form the pipe fittings side by side. When each rolling action is completed, the The rolling die is then ejected / and the pipe is pushed forward by a distance between the rolling dies. The rolling die is then used to perform the rolling operation on the previous procedure to make the pipe pass the most 455657.

In the rolling die wheel set of the subsequent rolling operation, in order to complete the ordinary ball plug of the required size, 'the ball plug is connected with the ball plug and then a whole series of ball plug embryos are formed.' The lathe tool of the bed is used to load off the load-breaking position of the ball plug, which has formed a complete ball plug. Still another object of the present invention is to provide an improved method for producing a universal ball plug. It uses pipe fittings as a material and uses a number of side-by-side forming dies to intermittently progressively form the pipe fittings; Punching to form a whole series of ball plug embryos that are connected to each other. Then, by using a lathe tool, when the ball plug is released from the stamping die, each ball plug of the connection is cut off to achieve rapid ball plug formation. And can reduce the defective rate and the processing cost.

(D) Each rolling die wheel set will advance the distance of the rolling die wheel sets every retreat. The rolling die wheel set presses the pipe fitting which has completed the previous rolling process; (e) The pipe fitting is rolled by several The wheel set advances in order to make the formed ball plug from small to large rolling die and internal arc, so that the ball plug is rolled out of the die by the rolling die and forms a whole series of interconnected; (f) The whole series of ball plugs are individually cut off at the cut-off line to form a complete ordinary ball plug with a water outlet opening at both ends; therefore, each rolling die wheel set is used to simultaneously roll and pipe the pipe in different directions, and at the same time Progressively, and the rolling dies through each rolling die wheel set are different Page 10 4 5 5 65 7 Six, the scope of the patent application circular arc 'to progressively connect the pipe fittings, which can prevent the rapid formation of pipe fittings and plugs, and save processing costs ^ y' reach the ball The improved manufacturing method is to use pipe fittings as the material and the scoop. For intermittently rotating pipe fittings, do (a) intermittent progressive stamping of several stamping forming die groups side by side; (b) each stamping die set has the same number of stamping dies, The corners are distributed on the periphery of the pipe fittings, and the in-mold arcs of each stamping die are based on the arc of the size required to complete the forming of the ball plug; (c) The stamping and forming die group simultaneously punches and ejects the pipe fittings. Reciprocating progressive stamping forming action, after several stamping dies reach a fixed point, the tube is punched into a whole series of interconnected ball plug embryos; (d) Borrowing a lathe tool, the ball plug is released from the stamping die after forming At that time, each ball plug of the connection is then cut off by its cut-off line to form a complete ordinary ball plug with a water outlet opening at both ends; therefore, 'the punching dies are used to synchronously reciprocate the pipe in different directions. While gradually advancing, and is rotated intermittently through the tube member to press the stamping die stamping of the average pipe to prevent deformation of the ball plunger to achieve rapid prototyping and tooling costs by saving.
