This type of crimping equipment is generally transported to the erection site and
In particular, it is often used in high places with poor footing, and it is desirable to be able to move it easily by holding the hanging part 11. Therefore, it is quite heavy and requires a lot of effort to carry. Also, the jaw 2 at the upper end of the guide wall
The shoulder part 7a of the head cap contacts the inner surface of a, and a considerable pressure of 100 to 200 tons is applied when the material W is crimped.
As a result, stress concentrates on the jaws and the jaws are likely to be damaged, especially as shown in FIG. 4, the guide wall 2
Since the outer periphery 2b of the jaw is formed by a straight plane parallel to the axis of the main body, it does not have sufficient mechanical strength and is prone to cracking.

In the present invention, in particular, the outer periphery 2b of the jaws of the guide walls 2 is formed as shown in FIG. As shown, it has a curved surface with a bulge. Above hydraulic cylinder 1
A ram 4 is disposed on the lower side of the ram 4, and pressurized oil is supplied from one of the upper and lower hydraulic valves 12, 12' to operate the ram 4 within a stroke range. A horizontal material insertion opening 3 is provided between the side edges of the left and right guide walls 2, and a vertical passageway formed between the opposing surfaces of the guide walls 2 includes:
The lower die 6, which moves up and down by the operation of the ram 4, and the upper die 5 facing the lower die 6 are slidably fitted together. Then, a head cap 7 is dropped between the upper surface of the upper die 5 and the lower surface of the jaw 2a at the upper end of the guide wall 2, and a spring 1 is placed on one side of the handle 8.
The lock claw 9 for preventing rotation, which is always biased in one direction at 3, engages with the engagement groove 10 provided on the upper surface of the inner end of the jaw 2a, so that the head cap 7 is held in the jaw 2a. It engages with the lower surface of 2a.

Grooves are provided on both sides of the upper and lower dies 5, 6, and 14 is a sliding guide that engages with this groove. When the material W is clamped, as described above, the jaw 2a at the upper end of the guide wall is subjected to considerable pressure as the shoulder 7a of the head cap abuts against its inner surface. To prevent this stress from concentrating on the jaw, the inner corner of the upper jaw 2a and the shoulder 7a of the head cap are arranged so that the jaw 2a is spaced apart from the shoulder 7a of the head cap.
A void 15 is formed between them.

る。 In addition, the hydraulic cylinder 1 and the guide wall 2 integrated therewith are made of a titanium alloy material, but titanium alloys tend to have unevenness on the machined surface during the machining process, which can lead to cracks. A glass bead shot, in which powdered glass beads are jetted, is applied to the inner corner of the jaw 2a, which is particularly exposed to pressure. The head cap 7 that engages with the jaws 2a of the guide wall may be made of steel, but in order to further reduce the weight, it is effective to use a titanium alloy material for the head cap 7 as well. However, in this case, both the jaw 2a and the head cap 7 are made of titanium alloy, and when the titanium alloys repeatedly come into contact with each other, a so-called galling phenomenon occurs due to biting. Therefore, in order to prevent this, for example, the headcap 7 is left in a nitrogen ion generator for a predetermined period of time to undergo ion nitriding treatment to allow nitrogen ions to penetrate.
Additionally, surface treatments such as gas nitriding and hard plating are performed. As a result, the different materials come into contact with each other, and the galling phenomenon described above can be prevented.

According to the crimping device of the present invention, which has the above configuration, the hydraulic cylinder and the guide wall integrated therewith are made of titanium alloy material, so the weight can be reduced by about 30% compared to conventional steel ones, making it easy to carry. be. Since the outer periphery of the jaw of the guide wall is made into a curved surface with a bulge, the wall thickness of the jaw becomes large, and there is also a space between the inner corner of the jaw and the shoulder of the head cap. , the hydraulic stress is applied to the jaws in a distributed manner, increasing the mechanical strength of the jaws and preventing cracks.
