Description

Casting mould digital control cutting processing former
Technical field
The present invention relates to a kind of specialized nc machine tool, belong to the interleaving techniques field that non-traditional machine tool and casting mold are made.The present invention is suitable for the processing and manufacturing of casting mold, core.
Background technology
Casting is to obtain one of main method of engineering goods blank, is the important fundamental technology of mechanical industry.Casting industry is the important foundation industry of the national economic development, is the basis of pillar industries such as automobile, petrochemical industry, iron and steel, electric power, shipbuilding, weaving, equipment manufacturing, is manufacturing important component part.Along with variation, the personalization of product, the demand of single-piece, small lot foundry goods is more and more, especially in the product development development stage, and require with short production cycle, renewal speed is fast.Yet China's single-piece, small lot castings production are still continued to use traditional manufacturing process, not only the manufacturing cycle long, production cost height, and resource consumption is big.In order to address this problem, the digitalization fast manufacturing method of casting mold has been proposed, adopt casting mould digital control cutting processing former directly to process the sand base and obtain casting mold.
At present, the mode of production of casting mold has two kinds: traditional casting mold manufacturing and shaping casting mold manufacturing fast.Tradition casting mold manufacturing needs mfg. moulding die, and the cycle is long, cost is high, is difficult to produce high accuracy, casting mold that surface quality is good, can not satisfy the production requirement of the large-scale casting mold of small lot.At present, fast the manufacturing of shaping casting mold is used is based on discrete-stack shaping principle, its basic process is as follows: at first adopt selectivity jet binder or laser sintered method to form the two-dimentional synusia with certain pattern, be connected to form three-dimensional casting mold then between synusia and the synusia.But utilizing RP technique to make casting mold has the following disadvantages: owing to adopt processing successively, working (machining) efficiency is low, is unsuitable for the processing of large-scale casting mold; Because adopt binding agent or laser sintered sand grains is bonded together to form the closely knit casting mold of inner surface, gas permeability is poor, foundry goods is easy to generate defective; Owing to adopt layering processing, when some complicated faces of processing, can produce the step effect.
Deficiency at existing casting mold manufacturing technology, the present invention proposes digital control cutting processing former, adopt this forming machine can be fully without mould, produce the casting sand mold of different shape, for the single-piece that solves foundry goods, the production trial-production of small lot provide new carrier, use this equipment to shorten the production cycle simultaneously, boost productivity, be particularly useful for big part, small lot, complex-shaped casting mold processing.
Summary of the invention
The present invention is a kind of casting mould digital control cutting processing former that is used to cut the sand base, it is characterized in that this casting mould digital control cutting processing former is made up of main part that contains multiaxis (three and more than) kinematic system, universal or special sand mold cutting tool system and sand-removing system and the special use control software that matches with the sand mold Cutting Process.
The main part of described casting mould digital control cutting processing former, it is characterized in that, comprise the sand-removing system that can in time clear up the sand formation cuttings that processing produces, machining sand mold universal or special tooling system, can prevent the multiaxial motion system that sand formation cuttings pollute and be used for the special fixture of clamping sand base.
The special use control software of described casting mould digital control cutting processing former is characterized in that, described special-purpose control software is the dedicated numerical control software of developing at casting mold numerical control cutting processing technology.
The dedicated tool system of described casting mould digital control cutting processing former is characterized in that, the cutting tool of the interior band gas channel that air cooling and blast are integrated.
The sand removing device of described casting mould digital control cutting processing former is characterized in that, described sand removing device can adopt blast or inhale two kinds of working methods of sand.Under the blast working method, air-flow is near rotary cutter, and the sand formation cuttings that cutter head processing is produced in time blow open; Inhaling under the sand working method, adopting negative pressure that the sand formation cuttings that cutter head processing produces are in time siphoned away.
The casting mould digital control cutting processing former that is used for the digitlization Rapid Manufacturing Technology of the present invention is compared with existing casting mold traditional manufacturing technology and quick shaping manufacturing equipment and is had the following advantages:
1. efficient, quick, to compare with traditional handicraft, this casting mould digital control cutting processing former has saved wooden model and has made link; Compare with fast forming machine, this casting mould digital control cutting processing former can be realized high-speed cutting, shortens the R﹠D cycle of casting mold.
2. the casting mold that adopts this casting mould digital control cutting processing former to process, casting character is good.Compare with quick shaping, it adopts the integrated processing of sand base, the too closely knit problem in part that does not exist selectivity bonding or sintering to cause.
3. pollute for a short time, energy resource consumption is low.Whole process is to carry out in the environment of sealing, no waste gas or dust pollution have solved traditional casting mold job shop waste gas, the serious problem of dust pollution, and use the waste material that this method cutting produces can also the secondary utilization, as the manufacturing raw material of criticizing casting mold down, raw material have been saved.
