Abstract
The present invention relates to a method for casting conveying chains from metal materials, namely a method for making chain links of heavy chains, which comprises: a pipe is put in a sand mould by using a semicircular groove reserved in the sand mould for chain links; after molten iron is filled in the sand mould, the demoulded chain link wraps the pipe in a main connecting hole of the chain link and uses the pipe as the main connecting hole; auxiliary holes are then respectively processed. The method of the present invention has the advantages of convenient manufacture and raw material saving and ensures that the processing precision of the main connecting hole is high and uniform; the method of the present invention does not need the reshaping after the processing and extends the service life of the diameter of the hole.
Description
The present invention relates to a kind of method, both the manufacture method of chain-link of heavy chain with metal material casting conveyer chain.
Present large-scale means of transportation generally all is the conveyer chain that connects to form with chain-link of heavy chain, and this kind conveyer chain is durable; But the manufacture method heaviness of chain link, complexity.It is to make chain with mould earlier, processes main connect hole and tap hole respectively with drilling machine on chain link again.The master connects the hole because material is big, and hole depth is longer, and process velocity is slow, requirement on machining accuracy is high again, therefore makes both waste materials like this, wastes man-hour again.
The object of the invention is to provide a kind of main manufacture method that connects the chain-link of heavy chain in hole that need not to reprocess.
Technical scheme of the present invention is finished with following steps: the manufacture method of chain-link of heavy chain is such, the first step: with the main chain link sand mold that connects two symmetries of aluminium chain system in hole of band, it is identical respectively to leave two sizes in the both sides that the master of two chain link sand molds connects the hole site, the semi-round groove of position symmetry, open an aperture on a chain link sand mold therein, the tubing that distance is identical between two semi-round grooves in its length of well cutting and the chain link sand mold is put into the semi-round groove of one of them chain link sand mold, another chain link sand mold on the fastening, and make the semi-round groove of two chain link sand molds just clamp tubing, pour molten iron into by the aperture that a chain link sand mold is reserved, fill with back cooling naturally, the demoulding, take out chain link, tubing on the chain link is leant out part cuts away, the tubing in the chain link the main hole that connects; Second step: on two tap legs of chain link with drill bit respectively get out one with lead that to connect hole size identical, and the tap hole of two hole site symmetries, both the chain link manufacturing finished.
The chain-link of heavy chain that adopts the present invention to make, process velocity is fast, saves material, and the master connects the hole and the chain link time processing finishes, and the main precision height that connects the hole, need not shaping, has improved the service life in aperture.
Describe manufacture method of the present invention in detail below in conjunction with accompanying drawing:
Accompanying drawing 1, chain-link of heavy chain sand mold schematic diagram;
Accompanying drawing 2, chain-link of heavy chain sand mold sectional side view;
Accompanying drawing 3, chain link demoulding front view;
Accompanying drawing 4, chain link front view.
1 chain link sand mold among the figure, 2,2 ' semi-round groove, 3 tubing, 4 chain links, 5,5 ' tap hole, the 6 main holes, 7,7 ' tap leg of connecing
As shown, make earlier one with the identical aluminium chain of chain link shape size, and connect the both sides, hole site the master of aluminium chain and respectively make a garden column type probe, the diameter that the garden post is popped one's head in is 10cm.Be placed on the sand mold with the aluminium chain and make chain link sand mold 1, when making with aluminium type garden post probe extrusion semi-round groove 2, position of 2 ' and make its typing on chain link sand mold 1; On chain link sand mold 1, open an aperture again, after chain link sand mold 1 performs, begin to make chain link 4 with chain link sand mold 1.Earlier will be outer through being cut into pieces by the distance between two semi-round grooves 2,2 ' in the chain link sand mold 1 for the tubing 3 of 10cm, the tubing 3 of getting a well cutting is put into the semi-round groove 2,2 ' of chain link sand mold 1, the semi-round groove symmetry buckled on another chain link sand mold 1 and two sand molds of respective link sand mold 1 fastens then, aperture by chain link sand mold 1 injects molten iron again, after molten iron is filled with, allow chain link sand mold 1 lower the temperature naturally, the chain link 4 of moulding is taken out in the demoulding again, with cutting machine the tubing 3 that two ends on the chain link 4 lean out is cut away, its tubing of staying in chain link 4 serobilas then connects hole 6 as the master; With the drill bit tap hole 5,5 ' that respectively to open a diameter be 10cm, chain link 4 is with regard to completion of processing like this on two tap legs 7 of chain link 4,7 ' symmetric position.The chain link of making in this way one by one 4 is connected in series then can form heavy chain.
Claims (1)
1, a kind of manufacture method of chain-link of heavy chain is characterized in that the manufacture method of chain-link of heavy chain is:
