Battery accumulator

To investigate the behavior of the materials over longer periods of time Load, at room or higher and lower temperatures, it is with regard to the duration of the tests mostly necessary to examine several samples at the same time. Material test machines of the usual type are therefore because of their Relatively large acquisition costs and the space required for this purpose too expensive · To the economic? to keep the economic and equipment-related expense lower, therefore devices have been developed in which in a machine frame Several samples can be examined at the same time · One of the versions brings several samples in a common frame vertically and side by side in annular arrangement below, with each sample for itself is stressed by a spring or weight load. The impact that occurs when a sample breaks is transferred to the order and the other samples and thus influences the test sequence of the other samples in an uncontrollable manner ¥ eis-e · In order to examine the materials at elevated temperatures, the specimens enclosed by a single, tubular furnace, making all samples are only exposed to the same temperature

Temperatures, each sample is enclosed in an oven. These series devices have caused the shock when breaking a sample over the Konstrutkionsteile on the neighboring Transfers samples and thus disrupts the test procedure · These test conditions are also hereby relieved of Sample changed as a result of the resulting changes in the shape of the frame. Lie level test battery after the Firing aims to exclude the indicated imperfections and requires only a small amount of space and economic effort.

In addition, it is planned to obtain the lower traverse single frame by separating it, so that completely independent units result. These units are on a common base arranged, which means that the foundation work is only to be carried out for one underframe

In a version of the standing battery according to the innovation, the frame supports are with flat boundary surfaces provided · Another version uses a porm of Frame supports, which make it possible to arrange these completely or partially inside one another · Furthermore, a design is provided · in which a shock absorber for the loading lever directly arranged at the end of the same - and this shock absorber is supported by a third support, which by means of a beam is connected to the two front main frame supports.

The unit consists of the loading device for the Proten »which contains a two-armed lever 4. This lever 4 is mounted on a cutting edge 5 · The load is Generated by weight disks 7 via a hanger · A sliding weight 8 on the is used for fine adjustment of the load Lever 4 · The slidable weight 9 on the other Bxxde of the lever let zuia balance the various weights of the samples and the measuring devices provided. Bine oil brake 14 protects the loading device against impacts if the sample breaks.

At dera äoppelarinigen Eebel 4 is further via an intermediate link the upper clamping head 6 is articulated. Per lower clamping head 10 is attached to a spindle 11, which by means of cutter 12 and Lever 13 can be adjusted »

For experiments at elevated temperature, the sample can be used from a cylinder tube-shaped furnace 15 are surrounded

The frame consists of an upper crosshead 3 "the frame" supports 2 and a lower crosshead 3a

The supports 2 are expediently made of a rolled profile, the outer surfaces being flat, so that all the individual frames on the base 1 are placed as close to one another as possible can be.

The arrangement of the units can be seen alternately offset according to Alb.6, i.e., once the sample is forward,

In this case, ten has the shape of a lireeck.
