Technical field
The present invention relates to a kind of digitlization process equipment of big-and-middle-sized sand mold, belong to the interleaving techniques field of casting and digital control processing.
Background technology
Casting can produce complex parts, is a kind of main processing method of metal forming.Continuous aggravation along with market globalization and competition, the speed of model change is constantly accelerated, the demand of single-piece, small lot foundry goods is more and more, single-piece, small lot especially the sand mold fabrication process of heavy castings require with short production cycle, low cost of manufacture.Yet China overwhelming majority producers still continue to use traditional wooden model founding technology, not only the manufacturing cycle long, production cost height, and resource consumption is big.In order to address this problem, a kind of digitlization process equipment of big-and-middle-sized sand mold has been proposed.
At present, the mode of production of casting mold has three kinds: traditional sand mold manufacturing, be shaped sand mold manufacturing and based on the processing of the sand mold of general NC lathe fast.The manufacturing of tradition sand mold need be processed wooden model according to foundry goods, carries out the sandbox founding again and obtains casting sand type.Fast the manufacturing of shaping sand mold is used is based on discrete-stack shaping principle, and its basic process is as follows: at first the mathematical model with sand mold forms a series of synusia by Z to layering; According to the synusia profile information, every shop one deck molding sand optionally sprays adhesive or carries out laser sintered again; Pile up layer by layer, form three-dimensional sand mold.Sand mold processing based on the general NC lathe is exactly to adopt Digit Control Machine Tool also finally to obtain sand mold according to the numerical control cutting of NC programming carrying out sand lump.
The manufacturing of tradition wooden model sand mold is suitable for the production of foundry goods in enormous quantities, because the wooden model process-cycle is long, cost is high, is difficult to produce high accuracy, casting mold that surface quality is good, can not satisfy the processing request of single-piece, small lot.Utilizing RP technique to make sand mold has the following disadvantages: processing successively, and working (machining) efficiency is low, is unsuitable for the processing of large-scale casting mold; Binding agent or laser sintered sand grains is bonded together form the closely knit casting mold of inner surface, and gas permeability is poor, and foundry goods is easy to generate defective; Layering processing can produce the step effect when some complicated faces of processing.Adopting the general NC lathe to carry out the sand mold cutting has the following disadvantages: the sand mold machining can produce a large amount of antiquated sands needs cleaning in time, and machine tool is not had sand removal equipment; Produce blown sands in the cutting process, machine tool places below the processing sand base or precise motion parts such as near part guide rails, leading screw need tight protection.
Deficiency at existing casting mold manufacturing technology, the utility model proposes a kind of digitlization process equipment of big-and-middle-sized sand mold, adopt this equipment can be fully without mould, produce the casting sand mold of different shape, improve the range of work, shorten the production cycle, solve the sediment outflow problem of general NC machine cut casting mold.
Summary of the invention
The present invention proposes a kind of digitlization process equipment of big-and-middle-sized sand mold, provide advanced more, means more flexibly, be particularly useful for the sand mold manufacturing of single-piece, small lot, big-and-middle-sized foundry goods for solving the sand mold manufacturing issue.
The utility model, it is characterized in that: this equipment comprises the latticed processing platform of a hollow out (1), place the antiquated sand gathering-device (2) of processing platform below, be fixed in the X-axis (3) of lathe bed top, having on the X-axis (3) can be along the slide block (4) of directions X slip, be fixed in the Y-axis (5) on the X-axis slide block, having on the Y-axis (5) can be along the slide block (6) of Y direction slip, be fixed in the Z axle (7) on the Y-axis slide block (6), be fixed in the electric main shaft (9) on the Z axle slide block (8), the cutter (10) of clamping on electric main shaft (9), be fixed in Z axle (9) and go up and place near the nozzle (11) of cutter head, the tracheae (12) that links to each other with nozzle 13, magnetic valve (11) that the control gas that links to each other with tracheae (12) cut-offs and the source of the gas (14) that links to each other with magnetic valve by tracheae.
Processing platform in the digitlization process equipment of described big-and-middle-sized sand mold can process the locating hole that is used to install clamping tool, and the processing platform below has can install the antiquated sand gathering-device that steamboat moves, to make things convenient for the taking-up of antiquated sand.
Process tool in the digitlization process equipment of described big-and-middle-sized sand mold is ceramic milling cutter or empiecement diamond milling cutter or surface diamond coating milling cutter or overlay coating carbide-tipped milling cutter.
X-axis in the digitlization process equipment of described big-and-middle-sized sand mold, Y-axis can be that lead screw transmission also can be band or other device transmissions synchronously.
Source of the gas in the digitlization process equipment of described big-and-middle-sized sand mold comprises gas cylinder and air pump.
The digitlization process equipment of a kind of big-and-middle-sized sand mold described in the utility model is used for the sand mold manufacturing and compares with general NC lathe method for milling with existing casting mold classical production process, method for quickly forming and manufacturing and have the following advantages:
