Pineapple peeling device which used for slicing the pineapple to create a cylindrical pulp. The key goal of this research is to implement a pineapple peeler system to overcome the challenges encountered by small and medium-sized businesses, in which the system produced will minimize its time needed for the pineapple operation. From an engineering viewpoint, ergonomic concerns relevant to peeling have been discussed. For this project, the concept of the pineapple peeler has a cylindrical blade being used to strip the pineapple flesh. The benefits of this pineapple peeler established throughout this venture are that it can remove the leaves as well as the core of the pineapple, and also can peel the outer surface of that same pineapple. Before starting the device, the pineapple is installed in the holder of the machine. So, the first cutter is to remove the ends as well as the base of the pineapple. Following that, the pineapple surface can be extracted by using a cylindrical knife. The mechanism within that device has been used to monitor the entire function of the pineapple peeler system and therefore is interfaced with dual pneumatic tubes to operate the tool. The mechanical and electrical elements are the essential parts of this unit.
The vital issue when joining magnesium combination (Mg) and aluminum composite (Al) exists in the presence of development of oxide movies and fragile intermetallic inside the bond district. Be that as it may, dispersion welding is acclimated be a piece of these amalgams while not a great deal of issue. In this examination, an endeavor was made to break down the mechanical properties, for example, lap shear quality, Ram rigidity and microhardness for dispersion holding of AZ80 magnesium (Mg) and AA7075 aluminum (Al) disparate materials. The holding nature of the joints was checked by microstructure examination. This work is directed to get better understanding and portrayal of the dissemination holding of comparative and different metals. It additionally meant to acquire ideal parameters for dispersion holding of aluminum covering over magnesium composite with Aluminum amalgam. This work is led to get better understanding and portrayal of the dispersion holding of comparable and different metals. It additionally intended to get ideal parameters for dispersion holding of aluminum covering over magnesium composite with aluminum amalgam. These two metals are jointed inside the kick the bucket in the wake of completing surface treatment.
The tube connections in the cooling system are joints where a sleeve is crimped on the tube and then the tube is fitted between a nut and connector to ensure a leak proof joint. Earlier the crimping was done manually but the joints leaked in the field. A hydraulic tool is now available for crimping. The ability of the joint to prevent leakage depends on how well the sleeve 'bites' in the tube and how well the tube retains its original shape after crimping. These in turn depend on the (i) Material of the tube (ii) Material of the sleeve. Difference between the hardness of the sleeve and tube (with the sleeve being harder than the tube) Crimping pressure. Change in these parameters leads to different depth and amount of 'bite' and the extent to which the tube retains its original shape. A measure of the strength of the crimped joint is the amount of axial force needed to 'Pull Out' the sleeve after it has been crimped onto the tube. To create a variety of crimped joints where the parameters were varied. The size of the tube and thus that of the sleeve was not varied in order not to introduce additional variance in the parameters. A test set up to be created to hold a tube with both ends having a crimped joint in a tensile testing machine.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
