MANUFACTURING METHOD OF STRIKER FOR VEHICLE AND STRIKER}

TECHNICAL FIELD The present invention relates to a method for manufacturing a striker for an automobile and more particularly to the provision of an improved striker that performs a key function with a latch used in a door, a trunk lid or a tail gate of an automobile.

In general, a door, a trunk lid, a tail gate or a hood of a vehicle is provided with a latch for opening and closing the door and the like to the vehicle body, and the latch is engaged or released with a striker installed in the vehicle body at the corresponding position with the latch. The lid, tailgate or hood is configured to be rebuilt with the bodywork.

The striker as described above is configured to have various shapes and shapes, and the specific structure will be described with reference to FIG. 8.

The striker 1 to which the prior art is applied includes a base 3 made of a plate member having fixing holes 2 formed at both sides thereof to be fixed to a vehicle body, and a latch is interrupted or released at the center of the base 3. Coupling arm bar (Arm Bar, 4) of the rough shape consisting of a round bar member.

The arm bar 4 is coupled to the fixing hole 5 formed in the base 3 and then intermittently formed by fixing means such as rivets, caulking, welding, and bolt nuts.

In the prior art as described above, since the plate-like member is separated into a process of making a base through a pressing process, a process of making an arm bar by bending the round bar member, and a process of fixing the arm bar to the base, various processes (processes) are performed. Providing ease of manufacture becomes practically difficult because of the hassle that has to go through.

In addition, since the parts that make up the striker are made through various processes, the management of the parts is not performed at all, the management of all parts at once is not possible, and the production cost increases due to the increase in the number of labors. have.

In particular, not only the base and arm bar should be equipped with dedicated equipment, but also the arm bar and base must be equipped with dedicated equipment, respectively, so that the initial investment costs are excessive, and the ease of maintenance is provided. There is a problem that cannot be done.

In addition, even if the arm bar is coupled to the fixing hole formed in the base and firmly fixed by the fixing means, as time passes, the dimensional error between the fixing hole and the arm bar gradually increases due to wear and the like, and the play is performed. In addition to the vibrations and shocks generated during the process, the arm bar flows with respect to the base due to the shocks and vibrations generated during the operation of the latch.

If the play of the arm bar occurs, the arm bar moves during the driving process, causing the noise to be impaired, and when the door is severely opened and closed, the arm bar suddenly bends or breaks away from the fixing hole. Cause.

In addition, no matter how firmly the base and arm bar are secured by the fixing means, it is difficult to keep the two parts securely in a tightly coupled state. Many problems occur, such as shortening the life of the system.

Accordingly, in the present invention, a blanking process for completing the overall shape by using a plate-like material of metal material and the invention for making a fixed wing fixed in close contact with the vehicle by bending both sides of the blanked material. The striker is completed by the first bending process, the second bending process of bending the central portion of the material on which the fixed blade is formed to form the armbar, and the welding process of spot welding the armbar forming portion to prevent the gap or spaced apart. By using plate material, fixed blade and arm bar are integrated to achieve the purpose of maximizing productivity while reducing cost through reduction of process and light weight, and increasing the durability by increasing durability.

The present invention provides a base and arm bar striker through perforation and bending by using a single plate member, which significantly reduces the number of parts and the number of work, contributes to cost reduction, and improves productivity as well as long-term use. This is an invention having various effects, such as to contribute to the improvement of the striker quality by ensuring a smooth operation.

The automotive striker 100 to which the technique of the present invention is applied includes a blanking step S1 for completing an overall shape by using a plate-like material 101 made of metal, and bending of both sides of the blanked material 101. And a first bending process (S2) for making the fixed blade (102) in close contact with and fixed thereto, a second bending process (S3) for bending the central portion of the material on which the fixed blade (102) is formed to form the arm bar (103), The forming part of the arm bar 103 is completed by a welding process S4 to prevent the phenomenon of being opened or spaced by performing the spot welding 104.

In the blanking step S1, the fixing hole 105 for fixing to the vehicle and the armbar hole 106 for forming the armbar 103 are integrally formed. In the first bending step S2, the fixed blade ( When forming the 102, the reinforcing rib 107 is integrally formed at the position where the fixed blade 102 and the arm bar 103 are connected to each other, thereby preventing deformation of the completed arm bar 103 such as easy bending due to vibration or impact. Make sure

In another example of the present invention, the blanking step (S1) to form the arm bar hole (103) for forming the arm bar (103) and at the same time to secure the reinforcement at the lock position (108) to lock the latch is locked. The reinforcing plate 110 is further formed integrally with the outer side and the inner side of the arm bar hole 106.

The reinforcement plate 110 further has a reinforcement plate bending process S11 for bending the reinforcement plate 110 before bending the fixed blade 102 through the first bending process S2, and welding process S4. After firmly fixing the arm bar 103 through the) to further have a reinforcement plate finishing process (S41) to be bent in the form of wrapping the first reinforcement plate 110 bent to the front, rear of the arm bar 103.
