DESC:FIELD
The present disclosure generally relates to a field of component manufacturing in a pressing machine and in particular, to a die-set for forming a pressed component.
BACKGROUND
The background information herein below relates to the present disclosure but is not necessarily prior art.
Die-set, in general, are pre-formed dies that are being used in the manufacturing industry. The die-set is used to deform a workpiece material by applying compressive force or pressure so as to achieve a desired shape. The conventional die-set is provided with a preset profile of a component to be manufactured. These preset profiles are complementary to the desired shape of the component being formed. Thus, once the desired numbers of components are formed, the conventional die-set becomes unusable and required to be changed with a complete new die-set assembly. As a result, the development of the new die-set cast requires a lot of time and effort.
Further, the development and manufacturing of the new die-set to upgrade the size and shape of an existing component is time-consuming, costly, and increases the process lead time for processing the desired component. Also, the procedure of changing complete die-set for the new component necessitates numerous changes in clamping equipment, which adds to the human effort and assembly cost. Moreover, the stacking of the conventional die-set necessitates a significant amount of space, which increases the cost of inventory for storing the industrial waste and scrapped die-set.
Furthermore, the conventional die-set is made up of entirely metal, making them bulky as well as it is difficult to achieve the weight and stress distribution under compression load or pressure. Therefore, the replacement of the conventional die-set with every upgradation in the profile is difficult to handle. Thus, the conventional die-set lowers down the production efficiency as well as reusability of the die-set is not possible.
There is, therefore felt a need of a pressing machine having a die-set for forming a pressed article that alleviates the aforementioned drawbacks.

A conventional die-set, in general, are pre-formed dies that are being used in the manufacturing industry. The die-set is used to deform a workpiece material by applying a compressive force or pressure so as to achieve a desired shape or profile. The conventional die-set is provided with preset profiles of an article to be manufactured. These preset profiles are complementary to the desired shape of the article being formed. Thus, once the desired numbers of pressed article are formed, the conventional die-set becomes unusable. As a result, the complete die-set is required to be replaced with a complete new die-set assembly for every upgradation in the shape and size of the article to be produced.
Further, the casting of the complete new die-set assembly requires lots of time and human effort for every upgradation in the shape of the article to be produced, which in-turn increases the process lead time for producing the new pressed article. Additionally, with every upgradation in the shape of the article, the conventional die-set are becoming scrap, which in-turn increases the inventory cost and space requirements for scrapping the conventional die-set.
Furthermore, the complete die-set are casted of entirely metal, thus making it bulky. Therefore, the replacement of the conventional die-set with every upgradation in the profile is difficult to handle and time consuming.
To overcome the aforementioned drawbacks, the present disclosure envisages a pressing machine with a die-set for producing a pressed article. The die-set 100 is configured with a removable attachment for removably attaching a die 20 and a workpiece 18 thereon in an operative configuration. The die-set 100 is shown in Figure 1 in accordance with an embodiment of the present disclosure.
An embodiment of the present disclosure will now be described with reference to the Figure 2(a), and Figure 2(b).

The die holder 15 and the workpiece holder 10 are provided with a plurality of slots. These slots are characterized to optimize the weight throughout the structural body of the die holder 15 and the workpiece 10. The slots provided over the die holder 15 and the workpiece holders 10 are by means of a plurality of ribs 13.
In an embodiment, the plurality of ribs 13 enables uniform distribution of the weight and provides uniform strength throughout the structural body of the die holder 15 and the workpiece holder 10.
In another embodiment, the die holder 15 and the work piece holder 10 have rectangular configuration.

Further, during pressing operation the operative surfaces of the workpiece 18 gets deform under the compressive force of the die 20 mounted on the die holder 15. Thereby, a profile generated workpiece is produced with the preset profiles 20a of the pressed article therein. Therefore, the pressing operation is forming the pressed article by pressing the workpiece holder 10 bearing the workpiece 18 on the die holder 15 bearing the die 20. The deformation of the workpiece 18 to form the profile generated workpiece and the die 20 mounted on the respected operating surface of the die holder 15 is shown in Figure 5(A) and Figure 5(B).
Since the die holder 15 as well as the workpiece holder 10 is configured to removably attach the die 20 and the workpiece 18 respectively, therefore the same standard die holder 15 as well as the workpiece holder 10 can be used repeatedly for producing a number of different profiles by removably attaching the preset profile dies. Therefore, the scrapping of the entire die-set 100 is significantly reduced, which in-turn reduces the inventory cost and space requirements for scrapping the die-set 100. Therefore, the present die-set 100 is economical in long usage with respect to the conventional die-set.
Also, since the same standard die holder 15 and the workpiece holder 10 are used repeatedly to produce the different profiles; therefore the human effort required for casting the die-set 100 is significantly reduced in long usage of the pressing machine.
Further, a wear plate and a heel block are mounted to each of the die holder 15 and the workpiece holder 10. Typically, the wear plate and the heel blocks are configured to absorb any side thrust that may be exerted on the die set 100 during the pressing operation.
In an embodiment, the die block 16 has a cavity 24 therein; the periphery of the cavity 24 has the shape of a preset profile. The cavity 24 provided over the die block 16a is shown in Figure 4(B).

In an embodiment, the movements of the die block 16a and cavity 24 portions are controlled hydraulically.
Advantageously, the die holder 15 and the workpiece holder 10 are a slotted type, therefore weight of the die holder 15 and workpiece holder 10 is significantly reduced. Further, the die holder 15 and the workpiece holder 10 are supported by the plurality of ribs 13, therefore the strength and weight is evenly distributed across the die holder 15 and the workpiece holder 10.
