Description

Pole guide bush hole forming apparatus and pole guide bush manufacturing automation system using the same

The present invention relates to a pole guide bush through-molding apparatus and an automated system for manufacturing a pole guide bush using the same, and more particularly, to uniformly manufacture a pole guide bush used to install a head rest on the backrest of an automobile seat. The present invention relates to a pole guide bush hole forming apparatus and a pole guide bush manufacturing automation system using the same, which can improve the quality of the product while improving the convenience and safety of work by increasing the productivity of the product.

In general, the head rest of the car seat is coupled to the upper part of the backrest to protect the user's head and neck as well as provide the user with a comfortable driving environment. It is configured and used to adjust freely.

Referring to FIG. 1, a structure in which the headrest is assembled on the vehicle seat is described with reference to FIG. 1. The pole guide 23 for guiding 22 is positioned, and the pole guide bush 4 positioned below the pole guide 23 to support the pole guide 23 has a frame of the backrest 20 of the car seat. It is fixed to 21 and is comprised.

As shown in FIG. 2, the pole guide bush 4 includes a pair of pole guides for locating and preventing rotation (3) formed in front and rear symmetry at one end of the steel metal pipe 1, and the pair of front and rear poles. Consists of a pair of pole guide fixing hole (2) formed in the front and rear symmetry at a predetermined height lower portion between the guide position guide and the anti-rotation hole (3).

Referring to FIGS. 3 and 4, Korean Patent No. 10-0721303 is a process for manufacturing a pole guide bush that performs the function as described above.

(Step 1)

Prepare a metal plate with a suitable thickness with the pole guide bush, cut it to a suitable diameter and length as the pole guide bush, and fix the pole guide holes (2) at the left and right and the front and back positions of the pole guides before and after the top and the anti-rotation holes. (3) is formed by a trimming process at the same time through a metal mold | die.

(2nd step)

When plastic processing of the metal plate material (1) processed by the trimming process to the tubular body so that both ends of the welding line can be precisely abutted W-shaped banding of the metal plate, and bending once more to plastic processing into the tubular body, or The metal plate is bent into a U shape, and then bent once more to be plastically processed into the tubular body 4.

(3rd step)

By forming the tubular body 4 by plastic working, after inserting the inner ring mold 6 so that the shape of the hole can be preserved in the hole 5 of the tubular body provided, the tubular body is placed on the upper and lower molds 7 and 8. The tube 4 is demolded after it is pressed and pressurized and processed so that the tangent line 9 can contact with both ends of the tube 4 precisely.

(Fourth step)

By the above-mentioned process, the pole guide fixed tube 4 is completed by mutual welding by argon welding on the welding line 9 which the both ends of the tube contact with each other precisely, and after processing a welding part.

However, the above-described conventional manufacturing method is difficult to form into a single tube body by contacting the metal plate member W-shaped banding or U-shaped band, and then contacting the metal plate member, it is also difficult to form a uniform tube, and also the inner ring mold After inserting the tube by pressing the upper and lower molds, there is a hassle to make the tube has a problem of poor productivity and quality.

Meanwhile, referring to FIG. 5, a manufacturing process of another conventional pole guide bush is as follows.

First, cut the steel metal pipe for the pole guide bush to a certain length and round the end. (Second Step) Using a U-shaped hole mold, (third step) a primary pole guide position guide and a rotation preventing hole (U-shaped hole) are formed. (Fourth Step) Reverse the pole guide bush by using another U-shaped hole mold to form the second pole guide position guide and rotation prevention hole (U-shaped hole) using another U-shaped hole mold. (Step 6) Using the mold for forming the Pole Guide Fixing Hole (Step 7), insert the Pole Guide Bush in which the 2nd Pole Guide position guide and the anti-rotation hole (U-shaped hole) are formed in the mold core, and the 1st Pole Guide. After the fixing holes are formed, the pole guide bushes are reversed and inserted into the mold core to form the secondary pole guide fixing holes. (Step 8) Complete the pole guide bush after passing through the pole guide fixing hole of the pole guide bush.

Another conventional manufacturing method as described above is the pole guide position guide and rotation prevention hole (U-shaped hole) and the pole guide fixing hole after the first molding and then the second molding as it is difficult to be perfectly symmetrical work in the opposite direction pole guide Fixing holes are shifted from each other, which is impossible to pass through the fixing holes there was a problem that a defect occurs in the product.
