Abstract

The utility model discloses a sand casting scraper moulding machine for revolving body parts. The moulding machine comprises a support 1, an upright post 2, a first screw 3, a first guide sleeve 4, a beam 5, a second guide sleeve 6, a second screw 7, a vertical bar 8, a thrust bearing 9, a bearing fixing sleeve 10, a connection plate 11, bolts 12 and a scraper 13, wherein the first guide sleeve 4 can slide on the upright post 2; the second guide sleeve 6 can slide on the beam 5; a threaded hole is formed in the first guide sleeve 4, as well as the second guide sleeve 6, and after the moulding position is determined, the two guide sleeves can be fixed through the screws; one end of the vertical bar 8 is sleeved with the thrust bearing 9; the scraper 13 can achieve rotary moulding. The scraper can be moved through adjusting the guide sleeves, and the guide sleeves can be fixed through tightening the screws after the position is determined, so that the moulding is convenient and fast; compared with manual moulding, the precision and the efficiency are greatly improved; as the scraper 13 and the connection plate 11 are in detachable connection through the bolts 12, for different revolving body parts, the only requirement is to replace corresponding scrapers.

Description

A kind of rotary part sand casting strickle moulding machine

Technical field

The utility model relates to a kind of moulding machine, is specifically related to a kind of rotary part sand casting strickle moulding machine.

Background technology

As everyone knows, sand casting is a kind of casting method of producing foundry goods in sand mold, steel, iron and most of non-ferrous alloy casting all available sand mould casting method obtain, because the Modeling Material that sand casting is used is cheap and easy to get, Casting mold manufacturing is easy, to the single-piece production of foundry goods, produce by batch and produce and all can adapt in a large number, for a long time, be the basic technology in Foundry Production always.

In general, the technological process of sand casting is: molding sand, core sand preparation, coremaking, sand core drying, moulding, cast; As seen, formative technology is one of indispensable important process in sand casting, and the technique that traditional medium-and-large-sized rotary part moulding is adopted is so-called " melt pit " moulding, i.e. moulding in the melt pit in workshop, without sandbox or only use top box, operation is trouble, the amount of labour is large, and the production cycle is long; Small-sized rotary part, generally adopt special scraper plate striking casting mold, saves material and the man-hour of making apperance, go into operation fast, but troublesome poeration; Therefore, traditional rotary part sand casting formative technology production efficiency is low, and the piece surface precision of producing is low is that chipping allowance is more, increases the cost of follow-up machining, and the increase of chipping allowance has also caused resource utilization not high.

Summary of the invention

The utility model purpose is to overcome the deficiency of background technology, a kind of rotary part sand casting strickle moulding machine is provided, improve the mo(u)lded piece surface accuracy, be easy to following process, greatly shorten rotary part moulding time of medium-and-large-sized rotary part particularly, improve rotary part sand casting overall work efficiency.

For achieving the above object, the utility model adopts following technical scheme:

A kind of rotary part sand casting strickle moulding machine described in the utility model, comprise bearing, column, the first guide pin bushing, the second guide pin bushing, the first screw, the second screw, crossbeam, montant, thrust bearing, bearing adaptor sleeve, connecting plate, bolt, scraper plate, it is characterized in that, described column and described bearing are fixedly connected by welding;

Wherein, the first guide pin bushing and described crossbeam be fixedly connected by welding and with described column matched in clearance, the second guide pin bushing and described montant one end be fixedly connected by welding and with described crossbeam matched in clearance;

The first guide pin bushing and all be drilled with a screwed hole above the second guide pin bushing, after posed positions is determined, fix by tightening screw;

Described montant other end cover has described thrust bearing, and by described bearing adaptor sleeve, strengthens fastening;

Described connecting plate and described bearing adaptor sleeve are fixedly connected by welding;

Described scraper plate and all be drilled with the through hole of formed objects above described connecting plate, and by the removable connection of described bolt.

During moulding, by regulating the first guide pin bushing and the second guide pin bushing, and tighten the first screw and the second screw, scraper plate is fixed on position suitable in sand mold, artificial rotating blade, carry out moulding.

Owing to adopting technical scheme as mentioned above, the utility model advantage is: a kind of rotary part sand casting strickle moulding machine described in the utility model can come by regulating the first guide pin bushing and the second guide pin bushing the position of mobile scraper, can fix the first guide pin bushing by the first screw after location positioning, the second screw is fixed the second guide pin bushing, moulding is convenient, fast, compare hand moulding, precision and efficiency improve greatly; And scraper plate is connected the removable connection of bolt with connecting plate, for different rotary parts, as long as change corresponding with it scraper plate.

The specific embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing.

The utility model comprises bearing 1, column 2, the first screw 3, the first guide pin bushing 4, crossbeam 5, the second guide pin bushing 6, the second screw 7, montant 8, thrust bearing 9, bearing adaptor sleeve 10, connecting plate 11, bolt 12, scraper plate 13;

Column 2 is fixedly connected with bearing 1, and the first guide pin bushing 4 is fixedly connected with crossbeam 5 and with column 2, matches, and the second guide pin bushing 6 is fixedly connected with montant 8 one ends and with crossbeam 5, matches, and montant 8 other end covers have thrust bearing 9, and by bearing adaptor sleeve 10, strengthens fastening;

Connecting plate 11 is fixedly connected with bearing adaptor sleeve 10;

Scraper plate 13 is connected with connecting plate by the removable connection of bolt 12.

During use, regulate the first guide pin bushing 4, after determining the vertical direction position of moulding, by the first screw 3, it is fixed; Regulate the second guide pin bushing 6, after determining the horizontal direction position of moulding, same mode, be fixed it by the second screw 7, like this, just can start strickle moulding by the hand-turning scraper plate.
