Nineth step

Yaiza Guerra

This week the teacher (Julen) teach us how to make assemblies on CATIA . We started making a pretty simple assembly to used it like a example. While we make the pieces of this assembly the teacher teach us how to introduced the pieces in the assembly, how to move it once we introduce it, how to link one piece with another one…

So know that we know how the assemblies work we can start making the assembly of our die.

Some team members continue making the calculus, like last week. Other ones continue with the materials and the search of the commercial elements (the ones that we buy, like columns, sleeves…). Once the element are chosen they also draw it in CATIA.  In this way we can insert later the commercial elements  in our assembly and the design does not have to been done by one person only.

In the meantime , with the “Arbol” finished and knowing how to make assemblies, I start making the assembly that will be our design. I started drawing and introducing the elements that we already have. For example, we already have the frames of our die, also the press in which it is going to work. After making them I started drawing other pieces of our die. In the beginning draw it very simple, making only the outer shape of it with its corresponding measures. In this way we can see where each element goes and changes its position and measures if it is necessary. Later we finish the piece, which the help of other elements that are going to be related with it and based on the first and simple draw.

In this nineth week we continued with the same work of the past one, finishing the work that we have to make for the design of the die. Me and Anton continued and finished the calculations, making a Word for having it clean and organized. Meanwhile Diego continued wiht the materials for the die and Markel finding normalizated elements and doing it in Catia. Yaiza, with the Catia tree done, continued inserting previous done elements to the assemble of the die.

In the Julen`s Catia classes we learnt different ways to do a piece, using one or another tool for having the same result.

In EAE our business keeps going, doing the DAFO and having some explanatios.

This week we have learned to make assemblies in software Catia. We have done a simple assembly to learn it. Then we have to make the assembly of the die, so we have to practice.

I have continued making calculus of the die to define better the dimensions and cantity of our elements. Also I have looked different materials to asign to the elements. There are materials with different capacities (Mechanical and chemical properties) and we have to choose the correct one in the different cases. To finish we have searched the stansarized elements we need.

Eighth step

In this eighth week we continued with self work doing our rol in the team. All teamates continued doing a part of the poryect, and my part was to do the diferent calculations for the design of the die. The claculations we have done were about bending and cutting of the band; calculus for the awls and springs, and to dimensionate the die.

In Catia, Julen’s subject, we have done some parts and pieces to learn another new tools. Those tools were some like: copy/paste, translation, rotation etc.

In Ane’s EAE subject we have done theory for the business and making our enpresarial ethic.

Gaizka solved us some questions too, being attentive and helpfull for people who needed his help.

Once we choose the design of the sheet we can start designing the die. But before we started with it we need to do some previous work. We need to learn how to make an assembly on CATIA , we know how to do individual pieces but not how to put it together and attach one with another.  We also need to do the  “Arbol” in our assembly before we started designing on it and inserting the different pieces on it.  The called “Arbol” is going to be basis of design, the core of it.  It is the way we are going to organize our design, how many part is going to have, how are the pieces going to be ordered… It is a very important part of the design, very complicated one, and the first step to started with the design.

So this week the teacher (Gaizka) take one member of its team (me in the case of our team) to explain how to make this “Arbol”. We go to another room to do that , and after the explanation is completed and our questions are answered we go back to the classroom. When we explain what the “Arbol” is and how to make it to the rest of the team members. After that we need to make on our Arbol , with the explanations Gaizka give us and using the teachers Arbol as an example.

So this week I spent most of the time doing this Arbol, taking time to do that calmly to don’t fail doing it. Its very easy to mess it up and in that case you have to redo it or fix it. That is going to take a lot of time so is more efficient to take it calmly and do it at once instead of make it quickly and badly.

This is a work for one team member only so while I am with this the rest of the team members continued with others works to advanced the design. Two of my companions are making the calculus necessaries to know the size of some die pieces, to know the minimum distance between two components, the forces we are going to need to the different operations our die is going to do… Another two team members are looking the materials of different components   and pieces and looking different catalogues to look for components that we need or we can buy instead of making it in the workshop.

This week we have started designing our die. We have a lot of information about our project and we have to put it correctly in the design. Per example, we have a lot of dimensions of different pieces already, so we have put them in the software to draw.

 

First, Gaizka teach us how to make a design tree. In our case, in the tree there are 3 important parts:

1) Top set 2) Lower set 3) Starting data

With these parts we can start designing the pieces. Also we have learned how to make an assembly in the software Catia to start designing the die.

Later, we started to look at catalogs of standardized elements to put in the die. There are many companies around Durango that sold standarized elements, so is not very difficult to find the elements we need in the design of the die. Per example, there is Gallastegui. It is an important company here, in the Bask Country. Also, there is Unceta, that is in Elgoibar, and they sold a lot of elements of die sector.
