Embodiment Construction

[0018] Such as figure 1 , 2 , 3 and 4, the bellows end flattening tool includes a first component 1 and a second component 2 .

[0019] The first component 1 is cylindrical and consists of an upper section 11 and a lower section 12 divided axially.

[0020] The upper section 11 is hinged by a first half cylinder 111 and a second half cylinder 112 , and the hinge axis 13 is parallel to the axial direction of the first component 1 . The upper section 11 is provided with a stepped hole made of a small round through hole 113 and a large round through hole 114, the small round through hole 113 is located above the large round through hole 114; the small round through hole 113 is respectively arranged on the first half cylinder 111, The small semicircular grooves on the second half cylinder 112 are fastened together, and the large circular through hole 114 is formed by fastening the large semicircular grooves on the first semicircular cylinder 111 and the second semicircular cylin...

Abstract

A flattening tool for the end part of a corrugated pipe is characterized by comprising a first cylindrical component and a second rod-shaped component, wherein a stepped hole, formed by buckling of semi-circular grooves of a first half-cylinder and a second half-cylinder which are hinged together, is formed in the upper section of the first component; a small round through hole is positioned at the upper part of a big round through hole; the diameter of a first round hole in the lower section of the first component is equal to that of the big round through hole, and the first round hole is communicated with the big round through hole coaxially, and the lower part of the first round hole is coaxially communicated with a second round hole with small diameter; the second component comprises an internal section positioned in the first round hole, an external section positioned outside the first component, and a middle section positioned between the internal section and the external section; the diameter of the internal section is greater than that of the small round through hole in the middle upper section of the first component, and is less than that of the big round through hole in the upper section of the first component; the middle section penetrates through the second round hole of the first component and is in clearance fit with the second round hole. The flattening tool can effectively solve the out-of-flatness problem of the port of the corrugated pipe, and improve butting quality of the device, and is high in efficiency and good in flatness.

Description

technical field [0001] The invention relates to the technical field of metal bellows cutting, in particular to a device for incision treatment after metal bellows cutting. Background technique [0002] The bellows of the end-screen lower lead of capacitive equipment such as CT and bushing are grounded. When dealing with the cut-off of the bellows, it often causes the cut-off to be uneven, which affects the quality of the device butt joint. Some use methods such as filing and hammering to make the bellows cut flat, which is slow in efficiency and unsatisfactory in effect. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the object of the present invention is to provide a flattening tool for the end of the bellows, which can effectively solve the problem of unevenness of the end of the bellows, improve the quality of the docking device, and has high efficiency and good flatness . [0004] In order to solve the above...
