The hydraulic distributor can control the hydraulic pressure to the left and the right so that it is possible to operate either the left or the right horizontal moving cylinder individually.

Therefore, it is possible to form the wrinkles only on either the left or right side of the connecting bar by operating the horizontal moving cylinder and the vertical moving cylinder separately by the hydraulic distributor for fixing the connecting bar for the car seat.

As shown in FIG. 6, the method for joining the bracket to the connecting bar for an automobile seat according to the present invention includes the steps of pressing the end of the connecting bar to form a first wrinkle portion protruding outward from the outer circumference of the connecting bar step; A second step of fastening a bracket having a connection bar and a serrated hollow hole formed therein with the first corrugated portion by the first step; And a third step of pressing the end portion of the connecting bar fastened by the bracket with the movable mold to form a second wrinkle portion and fixing the bracket between the first wrinkle portion and the second wrinkle portion in the second step Feature.

That is, the bracket attaching method of the connecting bar for a car seat includes a first step of forming the first wrinkle portion 21 on the outer periphery of the connecting bar 20, a second step of fastening the connecting bar and the bracket 50, And a bracket is fixed between the first wrinkle portion and the second wrinkle portion by forming a second wrinkle portion 22 on the outer periphery of the connecting bar, In the process of forming the primary wrinkles in the bars, the primary wrinkles are formed on the outer periphery of the connecting bar and the serrated irregularities corresponding to the shape of the hollow holes 51 of the bracket are simultaneously formed.

The first step is as follows.

After the connecting bar is placed in the fixing part 10 of the mold apparatus, the connecting bar is fixed so as not to move.

The fixing part includes a lower fixing part 12 on which a connecting bar is placed and an upper fixing part 11 for pressing and fixing the connection bar placed on the lower fixing part from above.

A movable mold is provided on both sides of the connecting bar on the basis of a connecting bar fixed to the fixing part, and the connecting bar is formed by a forming process of the movable mold.

The movable mold 30 includes a jig body 40 which is linearly moved toward the connection bar 20 and a hollow portion of the connection bar 20 which is protruded from the tip of the jig body 40 The forming jig 31 is mounted concentrically with the insertion rod 41 and the insertion rod 41 so that the shape of the inner diameter corresponds to the shape of the hollow hole 51 of the bracket 50.

The front end of the forming jig presses the end of the connecting bar, and an insertion rod inserted into the connecting bar is inserted into the center of the insertion hole. At the front end of the forming jig, a machining groove 33 for forming serration- do.

Since the front end of the upper fixed end and the lower fixed end are provided with the corrugated groove 13 capable of forming the corrugated portion by the forming process of the movable mold, the primary corrugated portion is formed by the forming process of the movable mold.

The above two-step method is as follows.

The brackets are inserted into the serrated irregularities formed in the process of forming the primary corrugations of the connecting bars.

The bracket is formed with a sawtooth-shaped hollow hole having the same shape as the saw-toothed concave / convex portion formed on the connecting bar.

That is, the hollow hole formed in the bracket is fastened to the concave-convex portion formed in the connecting bar.

The above three steps are as follows.

The bracket is fixed between the primary wrinkle portion and the secondary wrinkle portion formed on the connecting bar by pressing the end portion of the connecting bar fastened by the bracket with the forming jig without the machining groove by the step 2 to form the secondary wrinkle portion will be.

According to another aspect of the present invention, there is further provided a step of shaping the shape of the uneven portion formed on the connecting bar.

The step of shaping the concave and convex portions formed in the connecting bar in the first step is further added so that the concave and convex portions formed in the connecting bar are formed to have the same size as the hollow holes formed in the bracket.

That is, the foaming jig used in the first step is replaced with a regular foaming jig.

The forming jig having the machined grooves used in the step 1 is separated, and the forming jig that is formed in the movable mold is joined to the forming jig.

The front end of the shaping jig has a corrugated protective groove surrounding the first corrugated portion and a machined groove formed in the corrugated protective groove and having the same shape as the serrated hollow hole formed in the bracket.

Accordingly, the connection bar is provided with concave and convex portions having the same shape and size as the hollow holes formed in the bracket, so that the connection bar and the bracket become more rigid.

According to another aspect of the present invention, there is further provided a step of shaping the shape of the concavo-convex portion formed on the connecting bar.

The step of shaping the concave and convex portions formed in the connecting bar in the first step is further added so that the concave and convex portions formed in the connecting bar are formed to have the same size as the hollow holes formed in the bracket.

That is, the forming jig used in the first step is replaced with a standardized forming jig, and the uneven portion is inserted into the insertion groove of the forming jig.

The insertion rod used in step 1 is separated from the movable mold, and the unevenness generating part 60 is provided in the movable mold.

The front end of the shaping jig has a corrugated protective groove surrounding the first corrugated portion and a machined groove formed in the corrugated protective groove and having the same shape as the serrated hollow hole formed in the bracket.

In addition, the concave-convex generating portion of the movable mold is operated by hydraulic pressure or air pressure to form a serrated concave-convex portion on the connecting bar.

That is, as shown in Fig. 12, the concave-convex generating portion provided in the movable mold and inserted into the insertion hole of the forming jig includes a hollow body case 61, a pressing rod 62 inserted into the case, And a protrusion forming protrusion (63) for forming a concave / convex portion of the connecting bar by a pressure bar.

In the outer circumference of the case, a plurality of mounting grooves are formed in the circumferential direction so that the protrusions and protrusions can be inserted, and protrusions and protrusions are formed in the mounting grooves.

Inside the case, there is provided a pressure rod which is reciprocated linearly in the horizontal direction by hydraulic pressure or pneumatic pressure. When the pressure rod is advanced, the protrusion forming protrusion is pushed outward in the case to form serrated irregularities on the connecting bar.

On the other hand, when the pressing rod is moved backward, the protrusions and protrusions are moved toward the inside of the case to form the concave / convex portions on the connecting bar and return to the original position.

As another example of the bracket coupled to the connection bar, a plurality of fixing holes are formed in the bracket, and the fixing holes 52 are spaced apart from each other by a predetermined distance in the circumferential direction with respect to the center of the hollow hole formed in the bracket .

After the step of inserting the bracket is completed, a part of the secondary wrinkle part is also inserted and filled in the fixing hole formed in the bracket together with the formation of the secondary wrinkle part in the third step.

Therefore, in the process of forming the serration-like hollow holes formed in the bracket in the serrated irregularities formed in the connecting bar and forming the secondary wrinkles in the connecting bar, a part of the secondary wrinkling portion is filled in the fixing holes formed in the bracket, The coupling of the brackets becomes more rigid.

Therefore, according to the present invention, the fixing unit, to which the connecting bar is fixed, is divided into left and right sides and moved in symmetrical directions by the respective horizontal moving cylinders, so that even when the size of the connecting bar fixed to the fixing unit is changed, There is a remarkable effect that does not need to be changed.
