Embodiment 1

[0031] Single blanking process is adopted.

[0032] Such as figure 2 As shown, make layout for incoming coil material. Monomer blanking process includes the following steps:

[0033] For incoming coil materials, cut off the triangular scraps A and B at the sides of numbers ② and ③ to obtain the required finished board C.

[0034] In this way, the material utilization rate was 71.9%.

Embodiment 2

[0036] The traditional uncoiling blanking process is adopted.

[0037] Such as figure 1 As shown, make layout for incoming coil material. The traditional uncoiling blanking process includes the following steps:

[0038] first resection figure 1 Part 1.1 and 1.2 trapezoidal waste; the second step cuts off figure 1 Part 2.1 and 2.2 of the triangular waste; the third step along figure 1 Cut off the track shown in 3.1 and 3.2, cut and separate the coil material, and produce two finished boards, which are main stacking and side stacking respectively.

[0039] In this way, the material utilization rate is 88.85%

Embodiment 3

[0041] The uncoiling and blanking process of the present invention is adopted.

[0042] Such as image 3 As shown, make layout for incoming coil material. The uncoiling blanking process includes the following steps:

[0043] S1, providing incoming coil material Q that is horizontally conveyed along the length direction;

[0044] S2, according to the layout set in advance, cut off the triangular area formed by the short side C1, the upper or lower side of the coil material Q, and the straight line where the side C4 is located as waste;

[0045] S3, cutting out two finished boards C along the direction of side C4;

[0046] S4, the incoming coil material Q continues to be conveyed horizontally along the length direction, and steps S2 and S3 are repeated to repeatedly cut the incoming coil material Q.

[0047] In this way, the material utilization rate was 95.41%.

[0048] Through the above research, the following conclusions can be drawn: 1, the material utilization rate of ...

Abstract

The invention provides an automobile panel uncoiling blanking technology. The shortest edge is set as a waste cutting edge, the waste area can be lowered, and therefore the coil material utilization rate is improved; the shortest edge is set as the waste cutting edge, after the length is decreased, disposable cutting can be performed, cutting steps are simplified, and the production efficiency isimproved.

Description

technical field [0001] The invention relates to a processing technology of an automobile plate, in particular to an uncoiling and blanking process of an automobile plate. Background technique [0002] Uncoiling blanking is a plate processing technology suitable for uncoiling, cleaning and oiling, leveling, blanking and stacking of steel coils in industries such as automobiles and steel distribution. Compared with traditional monomer blanking, uncoiling blanking has the advantage of high production efficiency and can significantly improve material utilization through reasonable layout, thereby effectively reducing material usage costs. At present, some large automobile manufacturers are increasingly adopting the uncoiling blanking process to process blanks in mass production. [0003] attached figure 1 It is the uncoiling blanking layout drawing of a certain part of a domestic joint venture automobile brand, which adopts the double uncoiling blanking process, including the ...
