Erichsen Model 100 Sheet Metal Cupping Tester

Simple, Manually Operated Sheet Metal Testing Machine

Model 100 Sheet Metal Cupping Tester

Model 100 Sheet Metal Testing Machine for manual operation provides a maximum drawing force of 30 kN and a blank holder force according to the standard, of 10 kN.

Model 100, is a bench mounted unit with a cast iron machine body and a cylindrical test head. To conduct the cupping test the sheet metal specimen or foil is entered into an opening through the test head. The screw-in blankholder is set for the sheet thickness using the scale provided. The test head is then tightened manually against a stop on the locating sleeve. This clamps the blank with a force of 10 kN as required by the cupping test standards mentioned above. The clutch pin is pulled outwards from the locating sleeve, the test head is turned clockwise and the cupping process commences. The cupping test value reached is displayed on a digital counter. The forming process and the appearance of the crack can be observed conveniently looking down onto the blankholder. In poor light, or when using the smaller test tools nos. 5 and 11, we recommend the use of a special microscope with battery operated lamp.

Application

The manually operated Testing Machine is intended for measuring the drawing qualities of ferrous and non-ferrous metal by means of the ERICHSEN CUPPING TEST in accordance with:

on sheet and strip from 0.2 to 1.5 mm thick (400 N/mm² tensile strength) and on foil material in thicknesses down to 0.005 mm. Because it is easy to operate the machine, it is particularly suitable for use in factories only involved with a limited amount of sheet metal forming, and applications confined to thinner materials.

How it works

Model 100 provides a means to measure the drawing quality of sheet metal with very little effort. By establishing the quality of material which is still just satisfactory for producing a particular drawn workpiece the lowest cost material suitable for the part can be established. The standardised ERICHSEN Cupping Test is useful for the Purchasing Department, as part of an order specification. The surface grain size is shown up clearly on the tip of the bulge produced in the Cupping Test, and this can be interpretted as a numerical value with the aid of the ERICHSEN grain scale. On this basis, the grain size of the sheet metal can also be fixed at the out-set. No special skills are required to operate the machine.
