Automobile hood bracket manufacturing method according to the present invention is composed of SEMI-PRO process, FORM'G process, EMBOSS'G / BEND'G process and PIERC'G / PART'G process as shown in FIG.

1) SEMI-PRO Process

The SEMI-PRO process is a process of cutting a raw plate of automobile in the form of a flat plate into a hood bracket.

As shown in FIG. 3, the hood bracket 100 of the vehicle includes a left hood bracket 100a and a right hood bracket 100b which are hinged to both sides of the hood of the vehicle. 100a) and the right hood bracket (100b) is a step of cutting using a press in the form of integrally attached.

2) FORM'G process

The hood bracket 100 in which the left hood bracket 100a and the right hood bracket 100b are integrally attached to each other through the SEMI-PRO process is in a state in which a plate material is cut and has a flat plate shape.

The FORM'G process is a process of forming the body portion 101 and the support portion 103 as shown in FIG. 1 by bending the plate-like hood bracket 100 first by a press.

3) EMBOSS'G / BEND'G Process

The body bracket 101 and the support 103 are formed by bending the hood bracket 100 of the flat form through the FORM'G process, and the hood bracket 100 in this state is a factor such as a spring back. Its dimensional stability is poor.

In addition, the support bar 105 formed at one side of the support part 103 is in a state of being positioned on the same plane as the support part 103.

EMBOSS'G / BEND'G process is formed by using a press on the body portion 101 and the support portion 103 of the hood bracket 100 having a flat shape as shown in Figure 1, the body portion 101 and the support portion ( By forming the reinforcing ribs 106 at the bending portions 103 are divided, the dimensional stability of the hood bracket 100 is increased, and the hood bracket 100 is prevented from being deformed even when an external force is applied.

In addition, as described above, the bending portion and the reinforcing rib 106 are formed, and the support bar 105 located on the same plane as the support portion 103 is bent.

4) PIERC'G / PART'G Process

In PIERC'G / PART'G process, the fastening hole 102 is drilled in the body portion 101 of the hood bracket 100 for bolting with the vehicle, and the hinge for fastening the hood and the hinge on the upper portion of the support part 103. The hole 104 is drilled, and the left hood bracket 100a and the right hood bracket 100b are cut and separated.

Automobile hood bracket manufacturing method of the present invention configured as described above is composed of a total of four processes to reduce the number of processes compared to the conventional hood bracket manufacturing method can significantly reduce the mold manufacturing cost and production cost, while maintaining the dimensional stability of the product Can be.

In six conventional processes, the present invention was reduced to four processes, and then F-TEST and T-TEST were performed using statistical analysis software minitab on 10 pieces of sample data to verify homogeneity of the quality of hood bracket. .

Table 1 below shows the results of analyzing hood bracket data produced through six conventional processes and hood bracket product data produced through four processes of the present invention.

T-TEST is an analysis method that compares the average of two or less populations and is widely used to statistically compare the data of two products. Therefore, T-TEST was compared with product data produced through six conventional processes and product data produced through four processes of the present invention. The results are shown in Table 1 below.

2-sample T test and CL: 6 steps, 4 steps 2-Sample T-Test of 6 vs. 4 Steps N (count) Average Standard Deviation Standard error of the mean 6 step 10 92.3180 0.0199 0.0063 4 step 10 92.3100 0.0183 0.0058 Difference = mu (6 steps)-mu (4 steps)
Estimated Difference: 0.00800
95% of difference CI: (-0.01001, 0.02601)
T-test of the difference = 0 (vs not =); T-value = 0,94 P-value = 0.362 DF = 17

Figure pat00001

Since the P-value is 0.362, which is greater than 0.05, the product quality of Steps 6 and 4 is statistically the same.

Therefore, the manufacturing method of the vehicle hood bracket of the present invention configured as described above is composed of four processes, which reduces the number of processes compared to the conventional hood bracket manufacturing method, and greatly reduces the mold manufacturing cost and production cost, but also results in dimensional stability of the product. Can be maintained.

Mold for manufacturing a hood hood bracket according to the present invention is the SEMI-PRO mold, FORM'G mold, EMBOSS'G / BEND'G mold 130 and PIERC'G / PART'G mold ( 140) and a total of four molds.

The SEMI-PRO mold is a mold which press-cuts the raw material of iron plate and processes the material into the hood bracket 100 disc in which the left hood bracket 100a and the right hood bracket 100b are integrated, and the FORM'G mold is the SEMI. The FORM'G mold which press-forms the hood bracket disc processed through the PRO mold to bend the body portion 101 fastened to the vehicle body and the support portion 103 supporting the hinge of the hood, wherein the SEMI- Since the PRO mold and the FORM'G mold are the same as the molds used in the six conventional processes, detailed descriptions of the SEMI-PRO mold and the FORM'G mold are omitted.

As shown in FIGS. 3 and 4, the EMBOSS'G / BEND'G mold 130 has left and right hood brackets 100a and 100b integral to the EMBOSS'G / BEND'G mold 130. A bending space portion 131 having a hole shape is formed downwardly where the support bar 105 formed on the same plane as the support portion 103 of the left and right hood brackets 100a and 100b is seated.

EMBOSS'G / BEND'G mold 130 is formed on the support portion 103 and the body portion 101 of the left and right hood brackets (100a) (100b) and the support portion 103 and the body portion 101 A reinforcing rib 106 is formed at a bent portion, which is a boundary portion of the support bar, and at the same time, the support bar 105 is bent through the bending space 131 as shown in FIG. 1.

That is, the EMBOSS'G / BEND'G mold 130 is formed by bending the support portion 103 and the body portion 101 of the left and right hood brackets (100a, 100b) dimensional stability of the hood bracket (100) Simultaneously with raising the support bar 105 to complete the product shape.

PIERC'G / PART'G mold 140 is a car through a perforator as shown in Figure 5 and 6 to the body portion 101 of the hood bracket 100 processed with the EMBOSS'G / BEND'G mold 130 And drilling the fastening hole 102 for fastening the bolts, and drilling the hinge hole 104 through the perforator so that the hood is hinged to the support portion 103, the left and right hood brackets (100a) (100b) cut and separated It is a mold.

According to the present invention configured as described above, the automobile hood bracket 100 having the support bar 105 is produced through four shortened processes, thereby significantly reducing mold manufacturing cost and production cost, and high dimensional stability. It is possible to produce a good quality hood bracket by maintaining the.
