Description
Technical Field
The utility model belongs to the technical field of tool fixtures, and particularly relates to a vertical supporting tool for a sheet tooth part.
Background
In order to ensure that the heavy-duty gear has good contact fatigue performance and cycle fatigue performance in the meshing process, the parts have the mechanical characteristics of high surface hardness, low core hardness and internal toughness. In terms of production, the heat treatment process type such as carburizing, carbonitriding or nitriding is generally selected to achieve the performance, that is, a certain content of carbon and nitrogen elements are infiltrated into the surface of the part to improve the surface hardness of the part. Wherein, this kind of element usually can adopt gaseous medium to accomplish the diffusion under high temperature heating, so in order to guarantee that the even infiltration of element can be to the part surface, need keep the clearance of certain size between the working face of part and part, can not laminate completely, prevents that the unable infiltration of element that leads to because of contacting completely.
Because the size of the hearth of the heat treatment furnace is limited, in order to pursue production efficiency and resource saving, tools such as a material rod, a material rack, a material tray, a chassis and the like are used for stacking parts in the production process for material preparation. For the sheet-tooth parts, the common material preparation methods are mainly divided into two modes of horizontal placement and serial placement. The flat placement means that the gears are placed on the material discs of the grid structure horizontally, and each layer of material disc is uniformly distributed with one layer of gear according to the diameter of the gear; the stringing means that the gear is hung on the stringing rod through a through hole in the center of the gear by using the stringing rod, and a plurality of gears are strung into a string to be finally placed on the material rack according to the thickness of the gear.
For the gear parts produced conventionally, although the stock preparation method can better meet the requirements of deformation and stock quantity, the stock preparation method has certain limitation on the structural characteristics of the parts and is more suitable for mass production parts with common structures. Taking a piece-tooth part as an example, a gear which can be normally produced by stringing or laying flat generally has the following characteristics: the serial-placing material-preparing type gear is symmetrical in shape, the thickness at the position of the through hole is thicker, the total self weight is lighter, and the phenomenon of eccentricity or crushing damage caused by serial-placing is avoided; although the requirements on the structure, the size and the weight of the flat stock type gear are lower, the instantaneous contact area of the part and quenching oil is obviously larger during quenching after the flat stock type gear is laid, and the part is more easily warped, so that the gear is suitable for the part with lower requirements on end jump. However, with the development of engineering technology, in order to meet various special transmission requirements, more and more parts with more complex design structures and stricter deformation requirements are gradually produced in mass production, and if the parts are produced according to a conventional material preparation method, the deformation qualification rate of the parts is obviously lower than the production specification requirement, so that a large amount of equipment productivity and raw material waste are brought, the deformation problem caused after quenching is basically difficult to obviously improve through repair, and finally batch scrapping is very easy to cause. Therefore, only by means of conventional stock preparation, it is gradually impossible to meet the strict requirements of new parts.
In order to enable the gear parts to be easy to generate eccentricity and ellipse during serial placement due to the asymmetric structure and the dead weight of the parts, the thickness of the position of the through hole is very thin, but the gear parts with strict requirements on deformation such as end jumping, diameter jumping, accumulation and the like after being heated during horizontal placement can be produced in batch, and a novel material preparation mode which can not cause the ellipse and the eccentricity due to the asymmetric structure and the dead weight of the parts after serial placement and can not skip the large part end after horizontal placement is required to be found.
