Problems solved by technology

[0002] Our company mainly produces parts on automobiles, including the upper plate of the front sub-frame of the car. At present, the upper plate of the front sub-frame of the car is formed by drawing, but the current drawing mold is due to the composition of the product. The thickness of the material is not equal, and the unequal thickness drawing die is used. The current production of the drawing die is not enough, the forming is not in place, and the effect is poor. Therefore, it is very necessary to solve the above problems.

Embodiment Construction

[0011] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with examples, which are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0012] Such as figure 1 As shown, the present embodiment provides a mold mechanism for stretching and forming the upper plate of the front sub-frame of an automobile with different material thicknesses, including an upper mold base 1 and a lower mold base 2; the upper mold base 1 and the lower mold base 2 Correspondingly arranged up and down; the bottom of the upper die base 1 is provided with a die 3 in the middle, the top of the lower die base 2 is provided with a punch 4 in the middle, and the top of the lower die base 2 is located on both sides of the punch 4 with blank holders 5; The drawing part 6 is placed between the punch 3 and the blank holder 5 of the lower die base 2 and the d...

Abstract

The purpose of the present invention is to provide a mold mechanism for drawing and forming the upper plate of the front sub-frame of the automobile with different material thickness. The height of the ring top reaches the set height (generally, the lowest point of the blank holder surface is higher than the highest point of the convex model surface), and then the drawn part is put into the blank holder. This kind of mold positioning is rough positioning of the contour. When the upper mold base moves down, the concave mold contacts the blank holder first to press the drawn parts tightly to prevent wrinkling and stacking of the drawn parts during the material feeding process. When the concave mold surface contacts the convex mold surface, After the drawing process is completed, the upper die base moves upward immediately, the die and the punch are separated, the ejector pin raises the blank holder to the set height, and the drawn product is taken out. Perform stretch forming.

Description

technical field [0001] The invention relates to the field of molding of the upper plate of the front sub-frame of the automobile, in particular to a mold mechanism for drawing and forming the upper plate of the front sub-frame of the automobile with unequal material thickness. Background technique [0002] Our company mainly produces parts on automobiles, including the upper plate of the front sub-frame of the car. At present, the upper plate of the front sub-frame of the car is formed by drawing, but the current drawing mold is due to the composition of the product. The thickness of the material is not equal, and the unequal thickness drawing die is used. The drawing dies currently produced are not sufficiently drawn, the forming is not in place, and the effect is poor. Therefore, it is very necessary to solve the above problems. Contents of the invention [0003] In order to solve the above problems, the present invention provides a mold mechanism for drawing and forming...
