Abstract
The utility model relates to a combination boat suitable for dysmorphism product sintering, including the boat main part, the graphite column who still places in the boat main part including the activity personally experiences sth. Part of the body, graphite column body upper surface is opened there is cylindrical cavity for load single special -shaped product. The utility model discloses can steadily place special -shaped product, keep the stability among this type of product handling, improve the product percent of pass by a wide margin. And this sintering boat can satisfy the sintering of the special -shaped product of different quantity, makes sintering batch maximize, and then improves sintering efficiency.
Description
Technical field
The utility model relates to a kind of boat, is specifically related to a kind of sintering boat of powder used in metallurgy.
Background technology
Sintering is operation very crucial in CEMENTED CARBIDE PRODUCTION, and the shape of sintering boat, size can affect final size and the combination property of hart metal product.At present, when hart metal product is as pick, blank sintering such as special-shaped product such as bullet core, ball etc., sintering boat is general flat-bottomed boat, and the flat underside boat of groove or hole is provided with on surface, for sintering different model and varying number special-shaped product, the defect existing for these boats is:
1. adopt flat underside boat, special-shaped product probably places shakiness, and especially in blank handling process, shove charge easily occurs dilapidated phenomenon with unloading in stove process, has a strong impact on the quality of sintered products, the substandard product of generation larger amt.
2., for a small amount of even single special-shaped product of sintering, the flat underside boat with groove or hole also leaves larger dress boat space after these special-shaped products of loading, and this can reduce batch undoubtedly, and then reduces the sintering efficiency of this heat.In addition with groove or hole flat underside boat to manufacture cost higher.
Utility model content
In order to overcome above-mentioned defect, the utility model provides a kind of combination boat being applicable to special-shaped product sintering, steadily can place special-shaped product, keeps stablizing in this series products handling process, significantly improves product percent of pass.And this sintering boat can meet the sintering of the special-shaped product of varying number, sintering batch is maximized, and then improve sintering efficiency.
To achieve these goals, the technical solution of the utility model is: a kind of combination boat being applicable to special-shaped product sintering, comprises boat main body, also comprises activity and is positioned over graphite cylinder in boat main body, described graphite cylinder upper surface has cylindrical cavity, for loading single special-shaped product.
The sidewall be made up of two graphite column bars and flat graphite boat base plate surround described boat main body.
Described graphite cylinder is cylinder or square body.
Described graphite cylinder is single or be positioned in boat main body in batches.
The height of described cylindrical cavity and diameter make array of sizes according to the special-shaped product of different model.
The height of described graphite cylinder makes array of sizes according to product height.
The height of described graphite column bar makes array of sizes according to the height of graphite cylinder.
The height of described graphite cylinder and graphite column bar arranges and ensures can to place another group graphite boat on graphite column bar and the special-shaped product that do not collide protrusion.
The utility model, compared with conventional art, has the following advantages:
1. column type or square-column-shaped graphite cylinder load the carrier of special-shaped product as one, and the cylindrical cavity in the middle of it can steadily place all kinds of special-shaped product effectively, and graphite column body can be positioned in boat main body flexibly, reposefully.Cylindrical cavity height and diameter can make array of sizes according to the special-shaped product of different model, meet the dress boat stability of the special-shaped product of different model.The height of graphite cylinder makes array of sizes according to the height of special-shaped product equally, and then makes array of sizes as the height of the graphite column bar of sidewall according to the height of graphite cylinder, and the useful load of product in sintering furnace is maximized, thus improves sintering efficiency;
2., for individual sample or the small lot sintering of the special-shaped product of certain model, the graphite cylinder of corresponding model and quantity can be selected, be loaded on conventional flat-bottomed boat together with non-special-shaped product, and not need to prepare to be applicable to the special-shaped boat that different in nature product fills boat.For the sintering in enormous quantities of special-shaped product, can select the graphite cylinder of respective amount, graphite cylinder can be arranged in flat-bottomed boat by close parallel, and efficiency of loading is maximized.For the special-shaped product of different model and varying number, the graphite cylinder of corresponding model and quantity can be selected neatly, the special-shaped product of different model varying number is steadily loaded in same flat-bottomed boat compactly.
A kind of combination boat being applicable to special-shaped product sintering that the utility model provides, the flexible introducing of graphite cylinder, special-shaped product can be made to stablize to be loaded in conventional boat, and the special-shaped product of different model can be made to be loaded in same conventional boat together with non-special-shaped product.This utility model structure simple and flexible, easy to operate, practicality is extremely strong, is a kind of desirable boat device being applicable to special-shaped product sintering.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of the utility model boat.
Fig. 2 is the plan structure schematic diagram of the utility model boat.
Detailed description of the invention
Below in conjunction with concrete example and accompanying drawing, the utility model is described in further detail.
As shown in Figures 1 and 2, a kind of combination boat being applicable to special-shaped product sintering that the utility model provides, comprises boat base plate 1, graphite column bar 2, graphite cylinder 3.Boat base plate 1 and two movable graphite column bars 2 form boat main body.Graphite cylinder 3 can be cylinder or square body.Having diameter in the middle of graphite cylinder 3 upper surface is D, is highly the cylindrical cavity of H, for placing the special-shaped product as 4,5,6.Graphite cylinder 3 is positioned on boat base plate 1 flexibly.
Cylindrical cavity diameter D in graphite cylinder and height H can make array of sizes according to the maximum dimension D 1 in different special-shaped product portion placed within, D2, D3 and height H 3, H4.The width of graphite cylinder is greater than D, and wherein D is greater than D1, D2, D3, and H is less than H3, H4.
The whole height H2 of graphite cylinder is less than the height H 1 of graphite column bar.H2 is greater than H, and H3+H2-H and H4+H2-H is all less than graphite column bar height H 1, ensures can to place another group graphite boat on graphite column bar 2 and does not collide the special-shaped product of protrusion.
The technical solution of the utility model is not limited to the restriction of above-mentioned instantiation, and every technology distortion made according to the technical solution of the utility model, all within protection domain of the present utility model.
