Abstract

PURPOSE:To compress continuously a test piece with optional compression quantity and compression time by holding the test piece between a couple of rams and pressing one ram hydraulically by a tapered roller. CONSTITUTION:The upper ram 21 is connected with a hydraulic system 20 and the lower ram 22 is connected with a slide chopper 34 to compress the test piece W by the upper ram 21 and lower ram 22. Further, a couple of tapered rollers 23, 24 are provided and a tapered roller CM is inserted between said rollers. Then, while the tapered roller CM is rotated by a hydraulic cylinder 29, the tapered roller CM is moved so as to push between the tapered rollers 23 and 24. Then, the tapered roller 23 pushes up the slide chopper 34 to compress the test piece W. Consequently, since the test piece is controlled and compressed hydraulically by making a set of three tapered rollers, the continuous compression under the various compressing conditions can be made and further, the continuous compression test of hot rolling simulation of a thick plate or the like can be performed.

<Prior art> As an example of a continuous compression test in a rolling simulation such as hot plate rolling, a hot (800 to 1.200°C) K-heated test piece is rolled in a tandem rolling mill, usually a 6-stand mill. There is a 6-bus pressure reduction. Therefore,
In the rolling simulation, assuming this rolling, rolling is performed six times in succession for each inter-bus rolling. For example, in this test, the first compression time is set to 0.1 seconds, the load is unloaded after compression, and the next compression is performed 2 to 10 seconds later. By simulating this rolling process, ■ Check the toughness, strength, etc. of the product material and use it to determine the pass schedule.

That is, FIG. 5 shows a compressor commonly called a ``camplastometer'', and by rotating an eccentric cam 1, a roller 2 is pushed up, and a lower ram 3 is raised. The upper ram 4 is fixed and if the specimen W is set between the upper ram 4 and the lower ram 3, the lower ram 3 will rise due to the rotation of the cam 1 and compress the specimen W. It is a structure. However, IA is an eccentric cam part, and 5 is a housing (pillar). However, in the case of the compression device shown in FIG.
The shape of the cam is fixed, and the structure is such that the next compression cannot be performed unless the cam shape is replaced, so continuous compression is not possible.

However, since the device shown in Fig. 6 controls the compression position, it is not possible to control the compression speed during compression with high precision.Especially, for the compression speed just before stopping, a plate material CP is used that matches the compression amount with good precision. 4 is an upper ram, W is a specimen, 11 is a movable roll, and 10 is a fixed rotating roll.
and 11 are rotated by the motor. This roll 10 and 1
A plate material CP according to the amount of compression is inserted into the gap S between the test specimens 1 and 1, and the lower ram 3 is raised to compress the specimen W. SL is a cylinder for operating the plate material CP. If the shape of the plate material CP is modified as shown in Fig. 7(b), compression can be performed four times in this example, but with this method, the length l of the plate material CP is very long and the equipment is large. This plate shape CP must be processed according to the drawbacks and test conditions, which is inconvenient in use.
