Wow, it is driven by two steps of descending, three steps of moving backward to a descending state, and four steps of rising from a backward state, but the terminal connection terminal manufacturing apparatus of the above configuration is processed adjacent to each other for step-by-step processing of the connection terminal. Each processing process is carried out by transporting the workpiece to the position. The processing platform moves forward and backward and moves up and down in the state in which both ends of the workpiece are accommodated in the respective locking grooves formed on the processing tray to move the workpiece. Since it is processed and moved to the next processing position, as described above, when moving while both ends of the workpiece are seated in the locking groove, the workpiece is moved inside the locking groove.

A third cylinder 44 fixed to the middle edge of ), and a moving part 45 connected to the third cylinder 44 to move back and forth and having a plurality of transfer pins 46 and guide bars 47 formed on one side thereof. , A movable transport unit consisting of a fixed portion 49 on which the movable plate 43 is fixed and a plurality of guide holes 49a connected to the transfer pin 46 and the guide bar 47 slidably therein Terminal connection terminal manufacturing apparatus comprising (40).
The method of claim 1,
The transfer pin 46 is fitted with an outer circumferential surface close to the guide hole 49a to prevent shaking of the cylindrical pipe 200, and at the same time, one side is formed smaller than the inner diameter of the cylindrical pipe 200, and the end thereof is conical or spherical. Terminal connection terminal manufacturing apparatus, characterized in that it has an insertion portion (46a) having a shape.
The method of claim 1,
The fixing part 49 further comprises an inclined part 49b extending outward to the side where the cylindrical pipe supply part 10 is located.
The method of claim 1,
The cylindrical pipe 200 formed on one side of the first seating portion 211 and flowing from the cylindrical pipe supplying portion 10 has a downwardly inclined surface 241 on one side so that the input into the seating plate 21 can be made stably. Terminal connection terminal manufacturing apparatus, characterized in that it further comprises an auxiliary seating portion (24) having a seating groove (242) on the other side.
In the manufacturing method of the terminal connection terminal,
The manufacturing method of the terminal connection terminal is a step in which each cylindrical pipe 200 is disposed above each of the plurality of seating portions 211, 212, 213, 214 of the seating plate of the lower mold, and the transfer pin is separated from each cylindrical pipe 200 (S1). )Wow,
Step (S2) in which the corresponding upper mold is lowered from the upper part of the lower mold so that each cylindrical pipe 200 disposed above each of the seating parts 211, 212, 213, 214 is processed;
The transfer pin 46 is inserted into each of the processed cylindrical pipes 200 so that the transfer pin 46 is inserted so that each cylindrical pipe 200 rises vertically upward and moves to the next seating portion at the rear. Step (S3) in which each cylindrical pipe 200 is lowered again and disposed on the upper portion of each seating portion 211,212,213,214,
In a state in which each cylindrical pipe 200 is disposed on the upper portion of each of the seating portions 211, 212, 213, and 214, the transfer pin 46 is separated from each of the cylindrical pipes 200 (S4), and each step is A method of manufacturing a terminal connection terminal, characterized in that it repeats and manufactures a connection terminal.
