Stable pipe exchanging and adjusting necking machine

Abstract

The invention discloses a stable pipe exchanging and adjusting necking machine which structurally comprises a power box, a machine body, a supporting frame, a clamping device and a control box. When the stable pipe exchanging and adjusting necking machine is used, a sleeve is necked, the sleeve is installed on a connector and is clamped and limited through mutual cooperation of a plurality of supporting and jacking pieces, and the sleeve is not prone to displacement in the necking process. A compression plate and a bearing block are extruded through inward convergence of buckling and pressing blocks, the compression plate, the bearing block and the buckling and pressing blocks can be matched to conduct necking and pressing treatment on the sleeve, necking treatment is effectively conducted on the sleeve, and the necking precision and the necking effect of the sleeve are improved.

Description

technical field [0001] The invention relates to the field of necking machines, in particular to a necking machine for exchanging and adjusting stable pipe materials. Background technique [0002] The necking machine is a kind of equipment that squeezes and shrinks the diameter of the steel tube mouth through hydraulic extrusion equipment. It is mainly used to shrink the connection port of metal or plastic pipes of the same caliber, so that they can get a suitable fit. The interface, through the adjustment element to assist the shrinking of the sleeve, when shrinking the sleeve, the areas that need to be improved: [0003] When shrinking the casing, the casing is placed on the shrinking body, and the casing is compressed through the shrinking body. During the process of applying pressure to the casing, the buckle block will follow the shrinking body Shrink inward to shrink the casing, because multiple crimping blocks cannot join together to clamp the steel pipe at once, so t...

[0003] When shrinking the casing, the casing is placed on the shrinking body, and the casing is compressed through the shrinking body. During the process of applying pressure to the casing, the buckle block will follow the shrinking body Shrink inward to shrink the casing, because multiple crimping blocks cannot join together to clamp the steel pipe at once, so that the steel pipe will be placed on the shrinking body because of insufficient clamping force.
