Vehicle load is a static distributed load in the middle of the longest tube and is 1/3 the tube length. Loading in the middle of the longest tube is a worst case for stress on a cage member. Square tube assumes bending with one side parallel to the load (think square vs diamond). The safety factors use the numbers in the table below for strength.
capters of individual tube range. Steel tubes – classification and terminology Mentioned terms of steel tubes are in standard EN 10079 or others (ISO 6929). Tube classification goes out several aspects: mode of produc-tion, cross section shape, tube ends treatment, sphere of tube usage. According to EN 10079 tubes rank among so-called long prod-
BASIC ROLL-FORM TOOLING DESIGN: PROCESS OVERVIEW, INSTRUCTION, AND TIPS. 1.0 INTRODUCTION. This paper is intended to provide "basic" Roll Forming Tooling design instruction and tips for the beginning or novice designer. In my experience, the ideas expressed in this report can be applied to many situations, but I will stop short of claiming that these are the …
The advent of rolling mill technology and its development during the first half of the nineteenth century also heralded in the industrial manufacture of tube and pipe. Initially, rolled strips of sheet were formed into a circular cross section by funnel arrangements or rolls, and then butt or lap welded in the same heat (forge welding process).

Round bars are made with sufficient stock on the outside diameter to guarantee clean-up at the nominal dimensions. Stock allowance is a function of the bar diameter. Example: 3.00" + 0.118" = 3.118" tolerance is +/- 0.030" Max size = 3.148 Min size = 3.088. A 3.000" bar is guaranteed to finish at 3.000".

The Sheet Metal Rolling Machine works according to the principle of three point bending. The rotation of the driven rolls being utilized to feed the metal through the rolls by means of the frictional forces present between the surface of the rolls and sheet. No lubricant is used at its presence interference with the ability to grip.
In the above formula: f – Coefficient of rolling friction, take f = 0.008m. μ – Coefficient of sliding friction, take μ = 0.05-0.1d 1,. d 2 – Upper roller & lower roller diameter (m). D 1, D 2 – Upper roller & lower roller neck diameter (m). The size is not yet accurate in the design phase, the value can take D i = 0.5d i (i=1, 2). The lower roller drive torque T equals the sum of ...

To find L, we just have to divide each side by T: π × (D 2 / 4 − d 2 / 4) / T = L. Where π is the constant (3.141592654). The formula provides us with a length of any roll of material providing we have the thickness of the material and the inner and outer diameters of the cylinder. Make sure you use the same units for all inputs.
