Method for manufacturing large-scale flange forged piece by utilizing combined tyre die

Abstract

The invention discloses a method for manufacturing a large-scale flange forged piece by utilizing a combined tyre die, and the method comprises the following steps: step 1), setting a combined tyre die stack for storing the combined tyre die and a database; step 2), searching for determining whether the combined tyre die stack is empty or not, if so, turning to the step 5); step 3), finding an upper die enabling Dm to be not less than Dm initial and enabling hm to be not less than hm initial in the tyre die database, finding out all lower dies which can be combined with the upper die, performing pairing treatment on the upper die and the lower dies, screening out the combined tyre die which meets the initial size of a die cavity of the tyre die, calculating the volume of the die cavity, selecting the combined tyre die meeting the requirements as the finally selected combined tyre die and turning to the step 4); if the combined tyre die is not found, turning to the step 5); step 4), using the finally selected combined tyre die to manufacture the large-scale flange forged piece and turning to the step 6); step 5), manufacturing the brand new combined tyre die and manufacturing the large-scale flange forged piece; and step 6), further performing measurement and updating after the upper die and the lower die are used and placing and storing the upper die and the lower die into the combined tyre die stack.

Description

technical field [0001] The invention relates to a method for manufacturing a large flange forging by using a combined tire mold, which belongs to the field of free forging of flanges on a hammer, and in particular relates to a method for manufacturing a large flange forging by using a combined tire mold. Background technique [0002] Traditional large-scale flange forgings are usually forged with integral tire molds, such as figure 1 shown. For large-size flange forgings that are used in the petroleum and chemical industries, in order to meet the size requirements of flange forgings and ensure the strength of the tire mold, the wall thickness and quality of the tire mold for large flange forgings are large, so that the flange forgings The manufacturing cost of the flange is high; in addition, the large-scale flange tire mold is difficult to carry during use, and the storage space is large. When the tire mold is partially damaged, the entire tire mold is scrapped, which also...

For large-size flange forgings that are used in the petroleum and chemical industries, in order to meet the size requirements of flange forgings and ensure the strength of the tire mold, the wall thickness and quality of the tire mold for large flange forgings are large, so that the flange forgings The manufacturing cost is high; in addition, the large-scale flange tire mold is difficult to carry during use, and the storage space is large. When the tire mold is partially damaged, the entire tire mold is scrapped, which also leads to an increase in the cost of flange forgings.

In the design and production of tire molds, how to reduce the number of large tire molds, make full use of the flange tire molds in stock, and reduce the cost of flange forgings is a difficult problem faced by modern forging enterprises. Relying on manual methods and using traditional methods The tire mold manufacturing of large flange forgings cannot solve the above problems
