1932

A.M. Erichsen set up his firstsmall factory in Teltow near Ber-lin. Research and experimentsled to many further inventions.

the German State Chemico-Technical Institute successfullyapplied the ERICHSEN deep-draw-ing method to measure the ela-sticity and adhesive properties ofpaints and lacquers. The resultswere so convincing that the pro-cedure has since been adoptedby the paint industry all over theworld.

the inventive Norseman A.M.Erichsen introduced tools for cup-ping test dies to the market,without which the batch produc-tion of deep-drawn parts madeof sheet metal would hardly havebeen possible. Numerous innova-tions and improvements follow -ed. A.M. Erichsen not only posses-sed a forward-looking inventiveurge, he was also talented incommercial matters and soonenjoyed international renown.Satisfied customers were evidenceof the quality of his products.

1910It was probably true Viking spirit and the urge for discoverythat impelled the engineer A.M. Erichsen from Porsgrunn/Norway to settle and set up busi-ness in Berlin-Reinickendorf. Hisfirst invention, a water-cooledingot mould which to this dayconstitutes one of the most fre-quently used casting processesfor semi-finished products in thefoundry industry, enabled him tosecure the financial position ofhis company. A.M. Erichsen's nextinvention – the cupping test –was just as significant. This wasthe very first test method fordetermining the quality grade of sheet and strip metal.

This test procedure was initiallypatented, but has since beenadopted by all industrial coun-tries within the framework of theInternational Standards Organi-sation (ISO). Just as temperaturesare measured throughout theworld in Celsius or Fahrenheit, thestandard for sheet metal qualityis the ERICHSEN deep-drawingindex.

All our standard test equip-ment can be supplied with thiscertification which ensures fulltraceability through product

1975 19981949Following the turmoils of thewar and the loss of his company,A.M. Erichsen resolved to start upagain in the west of Germany. Hisbest partner – his son, Dr.-Ing. Per F.Erichsen – had studied mechanicalengineering in Hanover, graduatedat the Metallurgical Institute of theTechnical High School in Aachen,and did his doctorate at the CoalResearch Institute of Dortmund.Establishing the new company pro-ved difficult – without machines,tools, or construction drawings – ina factory kitchen of the ironworksin Sundwig. Ideas and determina-tion were the order of the day –initially the parts were made exter-nally and assembled by themselves.The modern factory we operatetoday is located not far away.

Björn Erichsen joined thecompany after completing histechnical and business manage-ment studies at the Polytechnic inMunich and at the George Wash -ington University in the U.S.A..After taking over from his father –who entered well-earned retire-ment from the active manage-ment of the business in 1977 anddied in 1988 – he is now the thirdgeneration to lead this companywhich has long since gainedinternational renown. Under hismanagement the range of instru-ments has been expanded, prima-rily by the addition of modern,non-destructive measuring devi-ces for surface engineering appli-cations.

The decision was made toincorporate tensile and pressuretesting machines, hydraulic andelectronic load and pressure cells,as well as calibration equipmentwith extreme measuring accuracyinto the production programme –reverting to the field of mechani-cal metrology earlier controlled bythe company. Support was provi-ded by a group of competent for-mer employees from ERICHSENWuppertal whose knowledge andexperience in conjunction withgreat insight into the latest in thefield of hardware and softwarehas resulted in a wide range ofmodern products.

2016In the course of 100 years theextensive Erichsen product rangehas been built up based on thetechnical fields of metrology andtest engineering. ERICHSEN paysstringent attention that theirmachines and equipment complyboth with the testing regulationsof national and international stan-dards and with the acceptanceterms of the industrial sector. Theseprovide the basis for global under-standing between the manufactu-rer and the user wherever the qua-lity of raw materials, semi-finishedand finished products is concerned.Design precision, perfect functionand absolute fulfilment of pur -pose: these attributes have toppriority at ERICHSEN.

Deep Drawing Tests. Sp

Test machines for all types of sheetmetal forming. Dependable testsensure efficient production.

The following two test methods provide only someinsight into the wide variety oftests that can be conductedwith our test machines. Custo-mized solutions to meet ourcustomers' requirements arechallenges which we face withconfidence.

One of the best known testmethods for sheet metal world-wide - patented as early as 1913

by the founder of our company -is the ERICHSEN Cupping Test. To conduct this test, a sheetmetal specimen is clamped bet-ween a blank holder and a dieand then dented (deep-drawn)with a hardened spherical punch.

pecimen Preparation. Sheet Metal Marking.

ERICHSEN universal sheetmetal testing machines – equip-ped with the appropriate toolsand/or accessories – are suitablefor conducting a wide range oftests related to metal forming:

Cupping test acc. to Olsenor PersozSquare cup testBore expanding testacc. to ISO/TS 16630

Deep-drawing cup testacc. to Swift

This

procedure is continued at aprescribed speed until it resultsin a fine, continuous crack inthe sheet metal. The displace-ment of the spherical punch till

cracking occurs is known as thecupping index >>IE<<, andrepresents a significant qualityattribute of the tested sheetmetal. This fast, cost-effectivetesting method is just as suit-able for use inincoming inspec-tion as for in-process controls –and that without any lengthyspecimen preparation.

The Deep-drawing Cup Test is amethod of testing sheet metalby which a circular plate (blank)is stamped from a strip of sheetmetal and then formed into acup using a drawing die and adrawing punch. The greatestpossible ratio between theblank and the drawing punch

diameter, which just permitsthe faultless production of acup, is called the Limiting Drawing Ratio »ßmax « and is aquality attribute for the for-ming abilities of the sheetmetal material. The ears, whichform as a result of the flow properties of the material areundesirable because theynecessitate rework on drawnparts when they occur in practice.Here again, it is possible todetermine the best suited sheetmaterial for the intended for-ming process by means of thedeep-drawing cup test.

The blank holder force of 10 kN con-forming to the standards, is appliedby means of saucer springs. Thedeep-drawing index is displayed onan electro-mechanic pulse counterwith a resolution of 0.1 mm.

Drawing force: max. 45 kN Test: ERICHSEN cupping testBlank holder force: 10 kN Sheet thickness: 0.1 - 2.0 mm

Drawing force: max. 30 kN Test: ERICHSEN cupping testBlank holder force: 10 kN Sheet thickness: 0.1 - 1.5 mm

Also suitable for testing materials of less than 0.1 mm thickness.

Simple hand-operated Sheet Metal Testing Machine

Model 111

This easy-to-handle cupping testmachine is intended for fast inco-ming inspection and quality controlon sheet and strip metals. Because ofits sturdy construction this machineis particularly suitable for in-processtesting.

Designed as a compact benchtopmodel, this testing machine requiresa minimum of space. The slantingarrangement of the test cylinderenables the user to remain seatedwhilst observing the test. The blankholder force and the drawing speedrequired for the execution of testsconforming to the standards, are setautomatically by actuating the start

button. Afterwards the deep-draw-ing test is also performed automati-cally.

The deep-drawing index is shown ona digital display (resolution 0.1 mm).As the testing machine works auto-matically and also stops automati-cally at specimen failure, it is possibleto delay this procedure by a potentio-meter. This is particularly necessaryfor an objective assessment of thecrack when testing thicker sheetmetals.

A special microscope is an optionalaccessory which enhances this pro-cedure.

Universal Sheet Metal Testing Machinefor Research and Development

Bulge Test Bulge Test

Beside the Nakazima test, thebulge test has become more andmore important over the last years.The figure shows a diagrammaticview of the testing assembly:

The test panel is fixed between thedrawing die and the blank holder.Below the specimen there is a cham-ber which is filled with oil. The metalsheet is clamped. The drawingpunch presses the oil upwardsagainst the test plate and deforms it.The forming process is effectedwithout any friction.

The special feature of this testingmachines is the increased drawingspeed of the drawing punch which,in addition to the normal drawingspeed range of 0 - 1,200 mm/mincan be adjusted, in an infinitelyvariable manner and independentof load, up to 3,000 mm/min. This isachieved by using a separate oil cir-cuit, fed by a pump with high volu-metric displacement. Contrary tothe high speed attachment based

on a nitrogen accumulator, here aconstant drawing speed behaviouris guaranteed over the total dis-placement of 150 mm. As to thetechnical design and the optionsavailable, including PC control andproportional valve technique, thismachines are similar to Models 145. The basic version of the machi-nes includes an oil/water coolingand have a power consumption of45 kW.

Universal Sheet Metal Testing Machinefor Research, Development and In-process Testing

It is possible to test specimens up toa size of 400 x 650 mm when con-ducting the hydraulic deep-drawingtest with the Bulge/FLC tester: Inaddition to the actual hydraulic for-ming process the construction ofthis machine also allows the use ofball punches with a diameter up to200 mm. The maximum drawingforce is 2,000 kN. To guarantee anexact reading of the required draw-ing force even in case of lower forces,they are divided in two measuring

ranges. At specimen failure the testcan be stopped both manually orautomatically. The capture and theevaluation of the measuring pointson the surface of the dome can beeffected by an optical measuringdevice during the drawing process.In the basic version the height of thebulge is detected by means of ameasuring probe placed on top, themaximum path measured being 100 mm, and displayed digitally.
