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
The invention belongs to bucket tooth Digitized manufacturing field, especially relate to the Digitized manufacturing method of a kind of mine excavator bucket teeth.
Background technology
At present, the scraper equipment such as excavator have a wide range of applications in metallurgy, mine, defence engineering, and bucket tooth is its main consumable accessory, in prior art, bucket tooth is generally overall processing, and wherein major part is sand mold casting, also has foam real type disappearance type and with industrial wax cavityless casting etc.Casting is the industry of a labour intensive, more domestic enterprises in process of production, manually pour into a mould as in reinforced in fusion process, casting process, carrying in casting falling sand scale removal process all without equipment, thus manual operation labour intensity is very large.Casting is big power consumer, and one of reason that foundry goods manufacturing cost is high is exactly that the energy consumption of casting is too high, 2 times of the energy consumption Yue Shi industrially developed country of China's average level or more some.Entirely with the experience of technical staff, and the precision of original blank is lower; So, generally to try out paraffin work mould by repeatedly revising, making test products, just by the measuring mechanical property of national standard, the time of this process need at substantial and fund.
Summary of the invention
The object of the invention is to overcome above-mentioned shortcoming and a kind of product development cycle that shortens be provided, reducing exploitation and production cost, accelerating the update of new product, improve the quality of products based on the excavator bucket teeth Lost Wax Casting modeling method of computer-aided manufacturing.The present invention can strengthen the research and development ability of new product, can promote developing rapidly of whole industry, and manufacturer is got the mastery in keen competition market.
Technical scheme of the present invention is: the Digitized manufacturing method of a kind of mine excavator bucket teeth comprises the steps:
1) draw bucket tooth part drawing, utilize the moulding of cad software to set up three-dimensional bucket tooth physical model.
2) casting process simulation simulation software is utilized, simulation Casting Technological Analysis and optimization.
3) model part of bucket tooth mold is generated.
4) bucket tooth paraffin pattern wax base is manufactured experimently.
5) cast trial-production paraffin wax base obtains cast iron bucket tooth blank.
6) mechanical test and paraffin pattern wax base parameter modification are carried out to cast iron bucket tooth blank.
7) paraffin pattern wax base is produced in batches.
Further, above-mentioned steps 5) medium cast iron bucket tooth blank carries out mechanical test, to predict the service behaviour of bucket tooth.
Further, above-mentioned steps 3) Computer secondary analog design and analysis, special design module is automatically considered the distortion of cast-iron blank part and is shunk, and carries out somatotype design by the Design wizard of this module.
Further, above-mentioned steps 4) in paraffin mould mould base be solubility paraffin mould.
Further, above-mentioned steps 7) in paraffin mould mould base complete processing by Digit Control Machine Tool.
Further, above-mentioned steps 1) to 3) in bucket tooth modelling with optimize adopt cast software.
The advantage that the present invention has and good effect are: owing to adopting technique scheme, die-manufacturing method based on Design of digital excavator bucket teeth is convenient, the risk of effective shortening castings production preparatory period and reduction new product development, improve Product Precision, reduce labour intensity, reduce costs and set up product database formation product family.
Accompanying drawing explanation
Fig. 1 is molding schematic flow sheet of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is elaborated.
As shown in Fig. 1, molding flow chart, the Digitized manufacturing method of a kind of mine of the present invention excavator bucket teeth comprises the steps:
