Problems solved by technology

[0003] The forging dies of the prior art have the following deficiencies: (1) The edge of the cavity of the traditional die is straight, and the corners are sharp-edged, and the material is easy to reflow during forging, resulting in lamination; (2) The traditional die has a The cavity depth of the upper mold is smaller than that of the lower mold. After forging, the product is formed in the cavity of the lower mold and is not easy to take out

Embodiment 1

[0020] Such as Figure 1-2 As shown, this embodiment discloses a forging die based on a round corner structure, which includes an upper die 1 and a lower die 2 that cooperate with each other. Both the bottom of the upper mold 1 and the top of the lower mold 2 are provided with mold cavities. The cavity shapes of the upper mold 1 and the lower mold 2 of the present invention correspond to each other.

[0021] The cavity of the upper mold 1 includes an upper resistance bridge 11, an upper product cavity 12 and an upper flash groove 13. The upper resistance bridge 11 has a ring structure, an upper product cavity 12 is formed on the inner side, and an upper flash groove 13 is surrounded on the outer side. One section or several intermittent sections of the upper resistance bridge 11 are arched outward to form an upper rounded structure 111.

[0022] The cavity of the lower mold 2 includes a lower resistance bridge 21, a lower product cavity 22 and a lower flash groove 23. The lower...

Abstract

The invention discloses a forging mold based on a rounded corner structure, and relates to the technical field of forging. The mold comprises an upper mold and a lower mold which are matched with each other. The bottom of the upper mold and the top of the lower mold are each provided with a mold cavity. The depth of the mold cavity of the upper mold is larger than the depth of the mold cavity of the lower mold. The mold cavities of the upper mold and the lower mold each comprise a resistance bridge, a product cavity, a flash cavity and a jaw, wherein the resistance bridge is of an annular structure, the product cavity is formed in the inner side of the resistance bridge, the flash cavity is formed in the outer side of the resistance bridge in a surrounding mode, and one or more interrupted sections in the resistance bridge are arched outwards to form the rounded corner structure. The forging mold has the advantages that laminated cracks are prevented from being produced on products after forging is finished, and forged products can be conveniently taken out.

Description

Technical field [0001] The technical field of forging of the present invention particularly relates to a forging die based on a rounded corner structure. Background technique [0002] Auto parts such as hub brackets, three-arm flanges, etc. are usually forged by high-temperature hydraulic methods. By placing the blank after heating in the intermediate frequency furnace in the product cavity of the lower mold, the upper mold is driven by the hydraulic cylinder to press down, forging, and then the upper mold is lifted, the product is formed in the cavity of the lower mold and taken out manually Products, complete the forging of products. [0003] The prior art forging dies have the following shortcomings: (1) The edge of the cavity of the traditional die is linear, and the corners of the forging die are sharp-angled, and the material is easy to flow back during forging, resulting in lamination; The depth of the cavity of the upper mold is smaller than the depth of the cavity of the...
