Definitions
- the invention is concerned with a method for the flexible manufacture of axle bridge housings.
- a model is usually created first. This is conveniently made of wood or wood-based materials that are easy to work with. From this wooden model, a plastic intermediate casting is made to produce a frequently used series model, which is a negative in terms of its shape to the wooden model. With the help of this "plastic negative” a “plastic positive” is cast as a series model. This intermediate model has the advantage over the original wooden model that it is more durable and less worn. It is used to manufacture the sand molds for the axle bridge housings.
- axle bridge housings In order to be able to produce geometrically complex axle bridge housings, correspondingly complex casting models are required. If the construction of these axle bridge housings is slightly modified for a new function in a partial area, a new cast model must first be created again. This is very expensive, in particular in the case of an axle bridge housing with numerous modifications for the most varied functions. It is often necessary to cast new variants of these axle bridge housings in order to meet new or changed requirements. In order to reduce this effort, the axle bridge could be divided into several housing parts that could be flexibly combined and easily replaced with newer partial designs, but this variety of parts is very complex and cost-intensive in terms of manufacture, storage and assembly. The additional flange surfaces or Connecting parts increase the volume and weight of the axle bridge. Otherwise the component load-bearing capacity may be restricted.
- the invention has for its object to reduce the manufacturing costs for axle bridge housings with a large variety.
- this object is achieved by simplifying the creation of the cast models by assembling the models from individual segments. By combining different segments, a large number of variants of the casting mold are possible. If the axle bridge housing is redesigned at a certain point according to new requirements, only a limited number of segments of the cast model have to be created again.
- the individual segments of the model suitably correspond to sections of the axle bridge housing with certain functionality. Models for axle bridge housings that are intended to perform certain functions can then be assembled according to the "modular principle". The sum of the functional segments forms the "model modular system". If a new functionality of the axle bridge housing is added as a result of expanded requirements, the modular system becomes one
- Model units for the series production of ultimately one-piece castings.
- these functional model units can be composed of several individual parts, e.g. B. from core and shell parts for hollow castings.
- the functional model units can be cast from plastic. Defects on the plastic model, which may occur at the points corresponding to the connection points of the assembled segmented model, can be reworked.
- the sand molds in which the castings are cast are produced according to these functional model units.
- the advantage of this indirect path from the original model to the cast part is that the modular model can consist of an easily machinable material, while the resulting one-piece model consists of a hard-wearing and resilient material.
- the model kit is spared.
- the segmented model is preferably made of wood or wooden materials that are easy to work with.
- the functional segments of the model for axle bridge housings correspond to housing parts for receiving axle shafts, differentials, wheel hubs or portal drives or housing parts for geometrically adapting the axle to the vehicle or the axle suspension. If, for example, an axle for a construction machine is to be changed so that it gives the vehicle greater ground clearance, the direct wheel drive can be replaced by a portal drive.
- the model for the new axle bridge housing could then be created by simply replacing its outer segments. In another case, in which a differential is replaced by a new it is replaced with other space requirements, only the functional segment of the axle bridge housing model would have to be replaced for the differential.
- This flexible manufacturing method is preferably used for axle bridge housings for construction machinery and agricultural vehicles.
- a segmented model 4 is assembled from a combination of functional segments 1 from an ensemble 2 of axis segments and an ensemble 3 from other axis segments.
- a functional model unit 6 is cast via a plastic intermediate casting 5, which acts as a “negative”, by means of which the sand molds in which the casting is cast are produced.
