Digital manufacturing method for bucket tooth of excavator for mine

Abstract

The invention provides a digital manufacturing method for a bucket tooth of an excavator for a mine and belongs to the field of digital manufacturing of bucket teeth. The digital manufacturing method for the bucket tooth of the excavator for the mine includes the following steps that firstly, a bucket tooth part drawing is drawn, and a cad software model is used for establishing a three-dimensional bucket tooth solid model; secondly, casting analog simulation software is used for simulating casting technology analysis and optimization; thirdly, a model part of a bucket tooth casting mold is generated; fourthly, trial manufacture is conducted on a bucket tooth paraffin mold paraffin blank; fifthly, the paraffin blank obtained after trial manufacture is cast, and a cast iron bucket tooth blank is obtained; sixthly, mechanical testing and paraffin mold paraffin blank parameter modification are conducted on the cast iron bucket tooth blank; and seventhly, paraffin mold paraffin blanks are produced in a batched manner. A mold manufacturing method for the bucket tooth of the excavator based on digital design is adopted, more convenience is achieved, the production preparation period of castings is effectively shortened, the risk of developing new products is lowered, product precision is improved, labor intensity is lowered, cost is reduced, a production database is established, and a product family is formed.

Description

technical field [0001] The invention belongs to the field of digital manufacturing of bucket teeth, and in particular relates to a digital manufacturing method of bucket teeth of mining excavators. Background technique [0002] At present, excavators and other scrapers are widely used in metallurgy, mining, and national defense projects. Bucket teeth are the main wearing parts. In the prior art, bucket teeth are generally processed as a whole, most of which are sand casting, and some Foam real type disappearing type and industrial wax real type casting, etc. Casting is a labor-intensive industry. Some domestic enterprises do not need equipment in the production process, such as feeding in the melting process, manual pouring in the pouring process, and handling in the process of casting falling sand cleaning, so the manual operation is labor-intensive. Foundry is a big energy consumer. One of the reasons for the high manufacturing cost of castings is that the energy consumpt...

Problems solved by technology

It all depends on the experience of the technicians, and the precision of the original blank is low; therefore, it is generally necessary to repeatedly modify and try out the paraffin working mold and make the test product to pass the mechanical performance test of the national standard. This process takes a lot of time and effort. funds
