Abstract
A kind of method for manufacturing scraper bowl by casting includes determining the volume capacity of scraper bowl.By selecting cope and lower moulding box from multiple copes and lower moulding box based on the volume capacity of scraper bowl, modular mold component is configured.In addition, the first core is selected from multiple first cores based on the volume capacity of scraper bowl.Cope, the first core, the second core and lower moulding box are assembled so that cope, the first core, the second core and lower moulding box limit scraper bowl shape die cavity together.The volume of die cavity depends on the selection of cope, the first core and lower moulding box.Melted material is poured into die cavity, and removes casting scraper bowl from modular mold component after melted material solidification.
Description
Technical field
The present invention relates to the manufactures of power shovel.More particularly it relates to it is a kind of be used for by casting technique come
Manufacture the modular mold component of power shovel.
Background technology
Scraper bowl is typically the equipment for being used as being used together with the earth mover of such as excavator, wheel loader etc, and
Bear load and the abrasion of high degree.In addition to can be other than bearing load and abrasion environment, power shovel must also be enough
It is firm, so as to can bear it is thousands of time or in some cases millions of times cycle (one cycle refers to penetrate into material,
That has dug and toppled over repeats each time).If the easy failure of power shovel, then, power shovel is replaced
It may be equivalent to huge component and labor costs and downtime.It can bear repeatedly to recycle without being broken
Reliable scraper bowl can be the important need of the earth mover owner.
Due to the size and weight and other factors of scraper bowl, scraper bowl possible price is expensive, and also in distress in manufacture
Degree.Scraper bowl is normally constructed to the weldment of plurality of steel plates.The big and heavier steel plate of these volumes is manipulated to be in alignment with each other and then
It is appropriately carried out the task that welding may be a difficulty and high cost.In addition, it has been recently discovered that, by by metalwork
The scraper bowl for welding together and producing is before expected service life is reached with regard to gradual failure.Since welding point is various
Structural strength under stress and strain is relatively low for the other parts of scraper bowl, therefore under normal conditions, scraper bowl
Failure is happened at the welding point.
The method that another kind manufactures scraper bowl in a manner of being different from welding together metalwork can be casting technique.
Scraper bowl is made by single part by casting technique, just eliminates any majority of splice etc. in this way.Molten metal is poured into mold
In the scraper bowl shape cavity with certain volume in, and molten metal occur solidify and post-processed that scraper bowl is made.So
And since scraper bowl is to manufacture application field to be used with various volume capacities according to them, to have with
All corresponding different mold settings of volume capacity may be expensive.
(be known as ' 639 to apply) for example, European patent application 2,149,639 disclosing it is a kind of manufactured by casting it is resistance to
Grind impact resistance power shovel.The power shovel is the wooden or metal casting identical with the shape of scraper bowl by the way that its shape is made
Modeling type and manufacture.The casting pattern is inserted into molding box, and sand casting is carried out to it using molding sand, is poured so as to be formed
Mouthful.Model is taken out from molding box to form die cavity.Ingot bar is heated and is poured into die cavity.The ingot bar hair poured into
Raw solidification, and part of the upper die and molding box are detached with the ingot bar after solidification, sand casting scraper bowl is made.However, disclosed in the application of ' 639
The manufacturing method of power shovel can not realize various sizes of digger shovel is manufactured by using one group of identical tool
Bucket.And in order to produce various sizes of power shovel, then it will need new casting pattern.To be laid in always in inventory
There is the corresponding casting pattern of all required sizes with power shovel, then may cost efficiency be lower.
The casting for the scraper bowl for having different volumes capacity is adapted to therefore, it is necessary to a kind of improved mold.
Invention content
In one aspect of the invention, a kind of method by casting to manufacture scraper bowl is provided.This method includes determining
The volume capacity of scraper bowl.This method includes configuration module die assembly to manufacture scraper bowl.The configuration packet of modular mold component
It includes and cope is selected from multiple copes based on the volume capacity of scraper bowl.The configuration of modular mold component is included based on scraper bowl
Volume capacity lower moulding box is selected from multiple lower moulding boxs.The configuration of modular mold component includes the volume capacity based on scraper bowl
The first core is selected from multiple first cores.The configuration of modular mold component further comprises assembling cope, the first type
Core, the second core and lower moulding box so that cope, the first core, the second core and lower moulding box limit scraper bowl shape die cavity together.
The volume of die cavity depends on the selection of cope, the first core and lower moulding box.This method is further included pours into die cavity by melted material
In, and casting scraper bowl is removed from modular mold component after melted material solidification.
In another aspect of this invention, a kind of model component for being used to prepare modular mold component is provided.Modularization
