Abstract
The invention relates to an integrated casting method of central slot of drag conveyor, belonging to the metalworking machinery without cutting scrap. The invention is characterized in that: it has integrates all the element of said central slot to be casting, with using vacuum disappear-mould integrated mould process. The invention has following advantages that: it can overcome the problems of brazing seam cracking, jointing distortion, short service life, and lower producing efficiency of present technique which joints several accessories into the one element, while it can save steel consumption and producing cost, improve the size stability, integration service life, quality, and the property of central slot.
Description
Technical field
The present invention relates to the metal machining technical field of essentially no smear metal, be specially the integral casting method of The middle pan of scraper conveyor.
Background technology
At present, all adopt cast-weld construction inside and outside the manufacturing nation of The middle pan of scraper conveyor, soon baffle plate ledge, shovel board ledge, left rack rails seat, right rack rails seat cast out at first separately, and then parts such as the middle plate that will process, square hole plate, interface board and back cover plate are integrally welded with it.Its operation is numerous and diverse, not only need a large amount of welders, welding rod, and the time have distortion and weld cracking problem to take place, often need that repair welding and press are correcting deformed could to be used, its overall dimensions poor stability, and adopt this cast-weld construction to make intermediate channel cost height, efficient is low.Owing to be subjected to the restriction of welding procedure, during material is all selected for use, low-alloy steel, wearability does not reach instructions for use, and the life-span is short, and it is low to cross the coal amount, has influenced the production efficiency of coal mining enterprise.
Summary of the invention
The integral casting method that the purpose of this invention is to provide a kind of The middle pan of scraper conveyor, it has overcome the deficiency of prior art, can save steel, welding rod significantly, integrated cost reduces greatly, has avoided welding deformation and weld cracking, good manufacturability, quality is good, and serviceability is good, has improved the overall dimensions stability and the service life of intermediate channel, cross coal amount height, the production efficiency advantages of higher.
Main technical schemes of the present invention is: a kind of integral casting method of The middle pan of scraper conveyor comprises and selects for use cast abrasion-resistant alloy to adopt lost foam casting process to cast; Foundry technology process comprise particle send out in advance → foam-formed → composition model bundle → swabbing → oven dry → sand temperature regulates, bury case, microseism moulding → vacuumize → vacuum-assist pouring → foam type vaporization → casting solidification, cool off → be up to the standards warehouse-in, it is characterized in that making the block mold of the vacuum expendable pattern mould of the single-casting that comprises following parts, parts comprise: the baffle plate ledge, the shovel board ledge, left side rack rails seat, right rack rails seat, middle plate, the square hole plate, interface board and back cover plate, and have following structural relation: middle plate is positioned at the centre of intermediate channel, be provided with back cover plate below the middle plate, the right side of middle plate is provided with the baffle plate ledge, the left side of middle plate is provided with the shovel board ledge, a left side, right rack rails seat is arranged on baffle plate groove and helps face, a left side, the arranged outside of right rack rails seat has the square hole plate, and the strip hole of band circular arc is arranged on the square hole plate; Block mold with this single-casting utilizes the casting technique of vacuum expendable pattern mould to carry out moulded.
The present invention has following significant advantage: 1, overcome in the prior art and a plurality of parts to be welded into parts to use, often occur weld cracking and welding deformation, life-span short, cross problems such as the coal amount is low, production efficiency is low; 2, save steel, welding rod significantly; 3, saved welding sequence, integrated cost reduces greatly, can reduce by 20 ~ 30%; 4, cancelled welded weld seam, thoroughly solved the problem of weld cracking, made the intermediate channel overall structure more trend towards rationally having avoided welding deformation and weld cracking, good manufacturability, quality is good, and serviceability is good; 5, adopted cast abrasion-resistant alloy, structural strength and wearability improve, thus overall dimensions stability, precision and the service life of having improved intermediate channel, life-span can be improved 1.5 times than cast-weld construction, significantly reduce coal mine following maintenance time, crossed coal amount height, the production efficiency height; 6, improved presentation quality, the intermediate channel any surface finish of disappearance mould block cast, clear-cut, attractive in appearance, casting quality is good, and casting manufacturability is good, and wide promotion prospect is arranged.
Be described further below in conjunction with embodiment and accompanying drawing, but not as a limitation of the invention.
Description of drawings
Fig. 1 is the The middle pan of scraper conveyor overall structure schematic diagram of the embodiment of the invention.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is its manufacture method block diagram.
The specific embodiment
Referring to Fig. 1, Fig. 2,1 is left rack rails seat, 2 is the square hole plate, 3 is that right rack rails seat, 4 is interface board, 5 is the shovel board ledge, 6 is middle plate, 7 is back cover plate, and 8 is the baffle plate ledge, more than eight members and have following structural relation: middle plate 6 is positioned at the centre of intermediate channel, be provided with back cover plate 7 below the middle plate 6, the right side of middle plate 6 is provided with baffle plate ledge 8, and the left side of middle plate 6 is provided with shovel board ledge 5, and left and right rack rails seat 1 and 3 is arranged on above the baffle plate ledge 8, left and right rack rails seat 1 and 3 arranged outside have square hole plate 2, and the strip hole of band circular arc is arranged on the square hole plate 2; Above-mentioned intermediate channel is designed to one, uses cast abrasion-resistant alloy, carries out the monoblock cast of vacuum expendable pattern mould.
Referring to Fig. 3, intermediate channel vacuum expendable pattern mould integral casting process is: and one design → particle sends out in advance → and foam-formed → composition model bundle → swabbing → oven dry → sand temperature is regulated, is buried case, microseism moulding → vacuumize → vacuum-assist pouring → foam type vaporization → casting solidification, cooling → warehouse-in is up to the standards, and comprise and manually unload sand, cleaning, the sand screening, operations such as cooling.After the cast, foam mould direct gasification, foundry goods moulding.Also can be aided with suitable heat treatment.
