The special feature of Models 145-60 and 145-100 is the increased drawing speed of the drawing punch which, in addition to the normal drawing speed range of 0 – 1200 mm/min can be adjusted, in an infinitely variable manner and independent of load, up to 3000 mm/min. 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.

The Testing Machine is driven electro-hydraulically. The test sequence is controlled automatically or manually as appropriate. A programme logic controller is used for the functions of the machine (optional computer controls). The drawing force and blankholder force as well as the drawing punch stroke are digitally displayed. The triple-acting hydraulic system in conjunction with the general design results in the following cost saving simplifications:

  • Blanking press in the test head
  • Hydraulic cup ejector
  • Fully-automatic test sequence.

Further technical advantages
  • Cylinder head with bayonet lock
    permitting direct access to drawing dies, blanking rings, blank holders etc. and quick and convenient changing of the drawing and blanking tools.
  • Infinitely variable drawing speed
    once set it remains constant throughout the drawing movement, independent of any change of load
  • Cardanic drawing die retention
    ensures the consistent, parallel clamping of the specimen, independent of variations in thickness.
Sheetholder Quick Release and Drawing Punch Stop (BSA- ZS)

During the drawing sequence the constant sheet holder force acts on a continuously reducing area of sheet metal under the sheet holder. The result is increasing specific pressure as the remaining flange reduces with the result that in the final phase of the drawing process and especially in cases with severe ear forming tendency, a squashing of the ear-ends will occur. For this reason, provision is made to release the sheet holder pressure completely at a preselected depth where there is no more tendency for folds to form.

The machine is provided with an digital display of the drawing punch stroke and a selector switch for either "BSA" or "ZS". When the depth of draw selected on the digital display unit is reached the drawing punch stops completely - in case of the "ZS" mode, or the sheet holder force is released - in the case of the "BSA" mode.

Hydraulically lifted test head

Hydraulic test head lifting function ensures a high rate of working safety and facilitates convenient testing due to the fact that the test head is hydraulically opened and closed.

Hot Drawing Equipment up to 550 °C

A further valuable addition to the possibilities offered by Model 142 is provided by the additional hot drawing equipment. In this, the blankholder and drawing die are heated in an insulated container and special provision is made to enable these then to be set up without difficulty on the machine. An electronic temperature measuring device is incorporated, and on this the preset intended temperature and the current measure temperature are displayed. The preset temperature can be set up to 550 °C, and in the test, the temperature remains constant within ±10 °C.

Special applications

This Sheet Metal Testing Machine can be customized and extended to accommodate special requirements, e.g. determination of forming limit curves (FLC) using a 3D.

Generally the sheet metal testing machine will be equipped with proportional technology and difference pressure measuring. As option it is possible to select a PC controls/regulation with software.

High Temperature Facility up to 900 °C

Due to the close co-opertion between manufacturer and universities, research institutes and the industry, the possibilities of application of sheet metal testing have multiplied. A high temperature facility enables to characterize the forming behaviour of metal sheets at up 900 °C. Contrary to the already existing hot drawing equipment (550 °C), here the test panel is inserted directly into the sheet metal testing machine. By means of a temperature measurement temperature profiles can be established.

Equipment for High Speed Tests

This optional equipment enables deep drawing tests to be conducted at elevated speeds that arise in practise. The speed of the drawing punch is preselected from 3 m/min to 25 m/min and is digitally displayed. The Sheet Metal Testing Machines, Models 142, and also all the accessories, can be varied within wide limits to suit special individual requirements. Please let us have details, therewith we shall be pleased to offer equipment to match your needs.
