Sheet metal Definition and 25 Threads

How do I calculate the force required to eject a sheet metal part from a die cavity. Coefficient of friction: 0.35 Surface area: 521.26 mm2 Elastic modulus: 68.9 GPa Material: 3003 Aluminium Material Thickness: 0.7mm Any help would be much appreciated. Thanks

In a house there is (typical of many 1950's vintage houses in my area) a framed cavity above the ceiling of a hallway and below the roof joists. It held a sheet metal heating duct "trunk line". The old ducts were removed since they had rusted through after being used (in the summer) with an...

I am talking about a sheet metal bender. Sometimes called a 'brake'. Bending metal of 1mm thickness or less. For those who don't know that's merely a long horizontal hinged metal bed upon which another sheet of metal is laid and clamped down just short of the hinge. Then closing the hinge...

hello every one can you help me in selecting the material to be used in the blade of cutting machine which will be used to cut galvanized sheet metal

hi every one can in you help me in finding the required force to cut sheet metal electrically as shown blew

Homework Statement A neutron is passing through a thin sheet of 115In of thickness 0.01 cm. Given that the density of the sheet is 7.31 g cm-3 and that the absorption cross section is 100 barns, what is the chance of the neutron being absorbed? You may assume the neutron is not scattered. a)...

I would like to produce the 3mm thick sheet metal steel part shown bellow but I have a few questions. I have my doubts about the whether the bending of the top right part (with the holes) will work. The 5 mm spacing has to be there as the tool will be inserted into a 3 mm surface Feel free...

Hi, I am new to this forum. I need to design an interference fit for a 1.5 mm thick SS ring. The interference fit is between this ring and another 1.5 mm thick SS sheet metal can without any groove. The ring is bent outwards at a specific angle.(please refer attached image) We know amount of...

My question is that I have to find the dimensions of a rectangular prism (cuboid), where none of the faces are square that will maximise its volume. The sheet metal I have to build it from is 120 cm by 80 cm. I don't even know where to start, I can do it if I'm given a height, width or length...

For a flat layout sheet metal part, is the bend line located directly in the middle of the bend allowance section, or is it inset from one side by a distance of the bend radius? So for a U-channel with an opening of approx. 4.56" (distance between inside of legs), would the distance between the...

Hello! I'm having some trouble understanding stress and strain rations in sheet metal forming. I understand that they're constants, but how do you calculate them? Or are they usually given? Thank you!

I want to know the force required to bend a piece of sheet metal in a hand bending brake. The sheet metal is clamped down and then bent upwards to a desired angle. The action is performed in the video below . Let's say I wanted to bend a piece of .032" thick AL 3' long to 110° (given the brake...

My project involves making a 5 ft*3 ft*4 ft (l*b*h) aluminium/stainless steel sheet metal box at the back of a slow moving pedal vehicle. There is no load on the sheet metal, except from small vibrations from road travel. My question is: 1. What gauge of sheet metal thickness would be enough...

Hello, How do I take into account the difference in stiffness when fabricating a part (for example, an L-bracket) from sheet metal or using an extrusion? In particular, where I work, it is "common knowledge" that extrusions are stiffer. How do i factor this in the stress and strain...

How can I calculate the maximum load a shelf made from sheet metal can take at a certain deflection limit? Have a number of different sizes and gauges and need to calculate without testing. Any help is much appreciated. The shelf is supported in the 4 corners similar to photo below...

Hi, I am trying to cut a parabolic curve in a piece of sheet metal using a numerically-controlled cutting machine (basically a very hard rotating router blade). The router blade is 10mm diameter. I want to achieve a parabolic cut in the sheet metal that adheres to the formula y=x^2 The...

Hi I am a Mechanical Engineering final year student from India. I need to calculate the forces(axial,tangential and radial) on the tool and the workpiece in the sheet metal spinning operation. Is there someway to find it theoretically or using any software? thanks

I am running a project on trying to find a method of detecting splits that are present in pressed metal. The system is to be placed into a manufacturing press line of car panels that will automatically detect and notify when a split has occurred during production. Some methods I have come...

Hi, ***I just noticed this that I posted this in the wrong section thinking I was in the engineering forum...sorry!*** I'm designing a racking system to store sheet metal coils (see attached sketch). I calculated the I and S values required and according to my calculations, 4 x 4 x 3/8...

I need a piece of .125" steel sheet metal to be 21" wide after a 1" lip is bent to 90 degrees on one side. How wide does the initial piece of steel need to be before bending in order to achieve this? I know it will be more than 22", but how much more? If I recall its fairly simple to figure...

Hi Could anyone help me in calculating the force required to deflect a sheet metal part (see attached excel file for details)

I'm looking to assemble two sheet metal parts (in the manner a bit like joining two halves of a box) in a simple manner that is either crimpable or some sort of snap fit. I have not seen any snap fit sheet metal designs and I wonder if there is any sort of standard practice (the aluminum sheet...

hello. can u help me with this planing execise manufacturers of sheet metal use rollers to produce the sheets. The sheets then pass along processing lines for painting. Transverse vibrations of these sheets results in a non uniform thickness of paint layers on the sheets. Electronmagnetic...

This is my first post on this site and I figured I would maybe get a good answer to this question. If the dimples on a golf ball are to reduce the amount of friction due to air resistance, why don't car manufacturers dimple the sheet metal on their cars to reduce coefficient drag?? Just wondering.

I am having the hardest time figuring out the center of mass of this problem. A sheet of metal is cut in the shape of a parabola (imagine that you have a parabola shape with the top being flat). The curved edge of the sheet is specified by the equation y=ax^2, and y ranges from 0 to b. Find...
