Embodiment

[0011] like figure 2 As shown, the present invention provides a good integral die of stamping effect, consisting of die base 1, die positioning block 2, die stopper 3, die bead 4, first die 5, second die 6 composition. Use five first dies 5, four second dies 6 and two die stoppers 3 to fit side by side into the groove of the die holder 1 and fix the first die 5 and the second die by the groove of the die positioning block 2. The position of the two dies 6, and cut pin holes on the die positioning block 2 and the die base 1 to fix the position of the die. Push down the first die 5, the second die 6 and the die stopper 3 with the die bead 4.

[0012] When working, the unloading block is pressed on the part of the inlaid concave mold, and the joint of the concave mold insert is not at the connecting rib of the steel belt product, which can effectively remove the imprint of the connecting rib.

Abstract

The invention provides an integral female die with a good punching effect, and the integral female die comprises a female die holder and is characterized in that the groove of the die holder is internally provided with at least two first female dies, at least one second female die and at least two female die blocks, wherein the at least two first female dies, the at least one second female die and the at least two female die blocks are arranged side by side, so that the first female dies and the second female die are integrally formed, the second female die is clamped between the two first female dies, two sides of the first female dies and the second female die are fixed by the female die blocks, the tops and bottoms of the first female dies and the second female die are respectively provided with a female die locating block for fixing the positions of the first female dies and the second female die, and the first female dies, the second female die and the female die blocks are pressed by die pressing strips. The integral female die provided by the invention has the advantages of enhancing the tensile strength of steel band products and improving the quality of products.

Description

technical field [0001] The invention relates to an integral die without sealing at the knife edge of the die, which is used for the die part of an automobile strip steel die and belongs to the technical field of dies. Background technique [0002] In the automotive steel strip products, due to the relatively high requirements on the imprint marks on the surface and the tensile strength of the automotive steel strip products, its general concave mold inlaid structure is as follows: figure 1 As shown, it consists of die base 1, die positioning block 2, die stop block 3, die bead 4, first die 5 and second die 6. Since the steel strip product needs to be close to the surface of the die, and the upper mold unloading block is pressed tightly, the punch can punch out the required steel strip product downwards. The knife edge of the die part is formed by the splicing of the first die 5 and the second die 6. Therefore, during the use of the die, the die formed by the first die 5 and...
