Description
Technical field
The utility model relates to a kind of specialized nc machine tool, belongs to the interleaving techniques field that non-traditional machine tool and casting mold are made.The utility model 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.
The utility model content
The purpose of this utility model is the deficiency at existing casting mold manufacturing technology, digital control cutting processing former has been proposed, 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.
The utility model is a kind of casting mould digital control cutting processing former that is used to cut the sand base, by the multiaxial motion system, universal or special sand mold cutting tool system, dedicated tool and sand-removing system are formed, it is characterized in that, stationary table is on base, portal frame can slide on the guide rail of workbench both sides, crossbeam is fixed on the portal frame, servomotor links to each other with transverse beam feed screw, saddle on the crossbeam can about slide, ram is fixed on the saddle, and machining spindle can move up and down on ram, and the gas outlet of blast pipe is in the machining spindle lower end, air compressor is connected with the blast pipe, is fixed with poly (methyl methacrylate) plate around the workbench.
Described casting mould digital control cutting processing former is characterized in that, has air flow passage in the described sand mold cutting tool.
Described casting mould digital control cutting processing former is characterized in that, the primary structure of described sand-removing system is that blast Guan Yiduan is positioned near the machining spindle, and the other end is connected with air compressor; Have the sediment outflow groove around the table surface, the lower end is connected with taper and leads the sand device, and the top of leading the sand device is connected with the fluting place of workbench, and collecting box is laid at the lower taper mouth place that leads the sand device.
The casting mould digital control cutting processing former that is used for the digitlization Rapid Manufacturing Technology of the present utility model 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.
