Automobile bumper forming mould forged piece

Abstract

A forming die forging for autobumper is characterized in that the forming die forging has a flush lettering shape surface with a lower middle part and two higher ends. The present invention has the advantages of that: 1. the cost and processing time are reduced, for the same die, the weight of the forging is reduced by a quarter or one-third after the improvement, and the die material cost for users is greatly reduced; 2. the bearing weight of the die processing unit is reduced, the quondam die can not be processed at the general machine tool, but the concave die can be processed at the general machine tool; 3. the processing time is greatly reduced and the processing cycle is also greatly reduced; 4. the quality of the die is obviously improved. The streamline direction of the metal fiber inside of the forging can be perfectly in accord with the part shape; compared with the cut off fiber of the prior art, the service life can be greatly improved. The middle concave part can realize great deformation, and the core part is compact and firm.

Description

technical field [0001] The invention relates to an automobile bumper forming die forging, which belongs to the field of plastic molds. Background technique [0002] In the production of plastic products, the first step is to process the mold according to the product design, and to process the mold, the mold material must first be selected, and after the mold material (mainly refers to steel) is selected, it must be forged to obtain the mold forging. In the prior art, die forgings formed by forging are generally square materials, such as rectangles or squares, but many products, such as automobile bumpers, are large in size and concave in the middle of the body. If rectangular forgings are used, During processing, the middle section needs to be cut off to form a concave shape. Therefore, its disadvantages are large material waste and high cost; the processing machine has a large load capacity and time-consuming processing; the metal fibers inside the forging are cut off, resu...

Problems solved by technology

In the prior art, die forgings formed by forging are generally square materials, such as rectangles or squares, but many products, such as automobile bumpers, are large in size and concave in the middle of the body. If rectangular forgings are used, During processing, the middle section needs to be cut off to form a concave shape. Therefore, its disadvantages are large material waste and high cost; the processing machine has a large load-bearing weight and time-consuming processing; the metal fibers inside the forging are cut off, and the mechanical properties are poor.
