Description

[Detailed description of the invention] This invention particularly involves inserting an electric wire into a sleeve,
This relates to a compressor used to compress this and connect electric wires.

Conventionally, as this type of compressor, one in which a lower movable die is moved up and down with a hydraulic ram relative to an upper fixed die is known. In this type of compressor, the upper and lower dies are detachable and replaceable so that it can be applied to compressing wires of various diameters. However, the joint surface between the moving die and the ram is formed flat, and since these two surfaces are brought into close contact with each other under a pressure of 100 tons or more due to the compression operation, a vacuum state is created between the two surfaces. For this reason, even if an attempt is made to remove the moving die for replacement after the compression operation is completed, it may not be possible to easily separate it from the ram.

The present invention was devised to eliminate the above-mentioned drawbacks of conventional compressors, and a corrugated plate was inserted between the ram and the moving die to allow outside air to pass through. It is characterized by this.

An example of implementation of the present invention will be described with reference to the drawings.
A fixed die 2 is detachably fixed to the upper part of the cylinder 1, and a movable die 3 is detachably attached to the lower part of the cylinder 1 so as to be freely raised and lowered by a hydraulic ram 4. The ram 4 moves up and down together with the moving die 3 by hydraulic pressure introduced into the cylinder 1.

In Figures 1 and 2, moving die 3 and ram 4
A steel corrugated plate 5 having grooves 5a is interposed therebetween. In this case, when the compression operation begins, the corrugated plate 5 is crushed, but even at the highest pressure, there are only a few grooves 5.
The moving die 3 and the ram 4 pass outside air between the moving die 3 and the ram 4, leaving the a, and the moving die 3 and the ram 4 have elastic force.
Trying to push the gap apart. Therefore, after the compression operation is completed, the movable die 3 and the ram 4 are not brought into close contact with each other under vacuum, and the movable die 3 can be easily removed due to the resilient restoring force of the corrugated plate 5.

In short, in the present invention, in a compressor that has an upper fixed die 2, a hydraulic ram 4 facing it, and a movable die 3 that is placed on the ram 4 and moves up and down together with the ram 4, the ram 4 and the movable die 3 Since a corrugated steel plate 5 having a spring force capable of forming a ventilation gap between the die 3 and the ram 4 during the compression operation is interposed between the die 3 and the ram 4, the corrugated plate 5 creates a ventilation gap between the die 3 and the ram 4 even during the compression operation. , the two do not come into close contact under vacuum, and after the compression operation is completed, the restoring force of the corrugated plate 5 separates the two, so the two can be easily separated and the moving die 3 can be quickly replaced. It is.
