ハウジングの製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION = Object of the Invention = [Field of Industrial Application] The present invention relates to a method for manufacturing a socket with a handle of a ball joint, for example, a tie rod end housing used in a steering device of an automobile.

って、タイロッドを製造していた。Tie rod end housing in which the shaft is curved in the same direction as the central axis of the housing (hereinafter referred to as "tie rod").
, A so-called ball stud-shaped material having a spherical head upset at one end is prepared, and a socket portion is formed on the spherical head. At the same time, the tie rod was manufactured by bending the shaft into a desired shape.

ッド1を鍛造成形することは不可能とされていた。However, as shown in FIG. 6, on the plane perpendicular to the central axis P of the housing portion 3 of the tie rod 1, the shaft portion 2 of the tie rod 1 is curved and is substantially the same as the central axis P of the housing portion 3. When manufacturing a tie rod 1 in which the shaft portion 2 is curved in a horizontal direction, forging with a crank press compatible with one-way bending causes the shape of the molded object to be complicated, so it may be applied locally to equipment such as mold equipment. Since the applied surface pressure is high, the load easily causes equipment failure. Further, since the housing part 3 is opened in substantially the same direction as the central axis P of the housing part 3, in order to forge-mold the housing part 3, the lower direction of the upper mold (the rising direction of the lower mold) is set to the housing. It is necessary to match the central axis P of the part 3. Also, as shown in FIG. 10, the maximum width W1 or more of the tie rod 1 on the plane perpendicular to the central axis P is not less than
Since it is necessary to prepare the material 5 having W2 and a large amount of surplus is generated when the tie rod 1 is formed, it is not possible to forge the tie rod 1 using a crank press capable of bending in one direction. It was possible.

In the case of manufacturing, as shown in Fig. 11, a rod-shaped material obtained by cutting (a ') a round bar to a required size is 1,100 to 1,200 ° C.
After heating to 1, the housing part 3, the connecting part 4 and the shaft part 2 are forged into a desired shape by hammer forging (f), and then the trimming press (e ') is used to remove the excess thickness, and the tie rod 1

湾曲させられる。At this time, the material setting part 22 of the lower mold 20 and the press part 23 of the upper mold 21
Since the space surrounded by has the same shape as the desired tie rod 1, the spherical head portion 7 of the curved slug 9 is formed in the housing portion 3 that is opened in substantially the same direction as the central axis P of the housing portion 3 of the tie rod 1. Thus, the end portion 10 is formed in the connecting portion 4 of the tie rod 1, and the shaft portion 37 of the curved slug 9 is curved in substantially the same direction as the central axis P of the housing portion 3 of the desired tie rod 1.
又、下型20の上端面25と上型21の下端面26との間に

より低減できる。Further, between the upper end surface 25 of the lower die 20 and the lower end surface 26 of the upper die 21, there is a surplus movement space 27 on the outer periphery of the material setting portion 22. Therefore, the load applied to the die device 19 by the molding forging (d) can be reduced by moving the excess thickness 11 into the excess thickness movement space 27.
余肉移動空間27の位置は、タイロッド1の軸線方向の
ほぼ中央に該当するので、タイロッド1の軸線方向のほ

ことになる。Tie rod 1 in the trimming press (e) process
The tie rod 1 with the extra thickness 11 is set on the material setting section 31 of the lower mold 28 having the same shape as the outer circumference of the finished product. The lower half 32 of the tie rod 1 which is separated from the surplus 11 is fitted in the material setting portion 31, but the surplus 11 moved in the outer peripheral direction of the tie rod 1 is hooked on the upper end surface 38 of the lower mold 28. Therefore, the upper half portion 33 of the tie rod 1 is exposed above the upper end surface 38 of the lower mold 28. Upper mold with trim mold 34 for punching out material
Lower 29. At this time, the trim mold 34 presses the tie rod 1 with the excess thickness 11 downward, but since the excess thickness 11 is hooked on the upper end surface 38 of the lower mold 28, the excess thickness 11 is left and the tie rod 1 is left. Only the punch will be punched downwards and the excess meat 11 will be removed.
以上の工程を経て、タイロッド1が製造される。 The tie rod 1 is manufactured through the above steps.

While moving the surplus in the outer peripheral direction of the curved slug, while molding the housing portion on the spherical head of the curved slug, in the same step as the central axis of the housing portion, the shaft portion of the curved slug is curved, Since the excess thickness is removed, it is possible to manufacture from a material having substantially the same diameter as the shaft portion of the tie rod, although it has a housing portion at one end and the product has a complicated shape in which the shaft portion is curved in two directions. Therefore, there is little extra meat,
The material yield is good, and since the surface pressure applied to the mold is not increased, the load applied to the mold is not increased,
Furthermore, the manufacturing time can be shortened.
