Universal Sheet Metal Testing Machine Model 146

Universal sheet metal testing machine, Erichsen cupping and deep-draw testing and FLC, up to 600 kN/1000 kN tensile force.

The special feature of Model 146-60 & Model 146-100 are the increased drawing speeds of the drawing punch which, in addition to the normal drawing speed range that can be adjusted, in an infinitely variable manner and independent of load.  This is achieved by using a separate oil circuit, fed by a pump with high volumetric displacement. Contrary to the high speed attachment based on a nitrogen accumulator, here a constant drawing speed behaviour is guaranteed over the total displacement of 150 mm. As to the technical design and the options available, including PC control and proportional valve technique, this machines are similar to Models 145.

Ear Measuring Instrument Model 126 PLUS

The Model 126 Plus ear measuring instrument is used to make axial measurements of deep-draw cups and can blanks. The typical standards here are DIN EN 1669 and ISO 11531. The device consists of a rotary table, a jaw chuck and a vertical measuring head (with measuring roller and length measuring probe). A jaw chuck secures and centers the cup. The measuring head can be adjusted to fit different sample diameters and heights. During one revolution of the rotary table, the measuring head records the shape of the cup edge (the so-called unevenness).  Ear measuring instrument, for cups of 15 – 50 mm diameter, max. 100 mm cup height

***Check out the new fully automatic Model 126 Plus Automatic ear measuring device capable of measuring up to 1500 cups/day.  Combing the proven and recognized measuring technology, software evaluation of our established Model 126 Plus now with new unique features such as camera-based rolling direction detection.

A brief overview of the process- the operator loads individual trays with up to 42 individual test cups. The interchanging magazine can take up to 5 of these trays and can be loaded throughout the ongoing measurement operation. The control system processes the measuring tasks independently and transmits the results to the user’s database.  For this purpose, a tablet is first taken from the changing magazine and fed into the handling system. A barcode scanner checks whether the position of the tablet is used and uniquely identifies the cup to be measured. If the cup cannot be identified, it is automatically ejected separately.

Identified cups are fed to the rolling direction detection module. Here, the precise position of the cup on the suction cup is measured in relation to the rolling direction. Only then is the earing measured, evaluated according to predefined algorithms (taking the rolling direction into account) and data determined transferred to the customer’s database with the ID read from the barcode. The entire process is displayed and can be observed and monitored via the integrated screens displays.    Magazine replacement, approx. every 3 hours.  Data is stored locally on the computer for up to 1 year.
