Abstract

The utility model discloses an automatic pipe end necking and sizing device, comprising a hydraulic oil cylinder, a mounting flange, a movable push plate, a sliding block, a sliding inner sleeve, a sliding sleeve, a module and a clamping block, wherein the mounting flange is mounted on the hydraulic oil cylinder, a piston is arranged in the hydraulic oil cylinder, the movable push plate is connected with a piston rod of the piston, the sliding block is arranged above the movable push plate and is sleeved in the sliding sleeve, the inner cavity of the sliding sleeve is in a frustum shape, the outer surface, contacted with the sliding sleeve, of the sliding block is in a frustum shape, so that the assembling clearance between the sliding block and the sliding sleeve is effectively prevented from being overlarge, and therefore axial movement in the machining process is avoided, and the machining quality is effectively ensured; the inner cavity sections of the sliding block inner sleeve and the sliding block are in a stepped shape, so that the machining requirements of steel pipes of different pipe diameters are effectively met; and the positioning is accurate, the machining requirement of precise positioning is effectively met, and during casing pipe machining, the clearance between two pipes can be effectively eliminated, so that the two pipes are coaxially assembled.

Description

The automatic reducing diameter-setting equipment of pipe end
Technical field
The utility model belongs to steel pipe throat sizing apparatus technical field, is specifically related to the automatic diameter-setting equipment of a kind of pipe end.
Background technology
At present, in the pipeline processing process, much need to carry out the reducing sizing processing to pipe end, prior art generally adopts the high thrust oil cylinder axially to promote mould, and pattern tool extruding steel tube end part makes it distortion.In the extrusion process, pipeline energetically clamp is clasped, can not move axially, in case the clamp chucking power is not enough, axial motion will occur, and the tube end deflection will not reach requirement, and pipeline is held the position and also cut can occurs, if and the clamp chucking power is excessive, pipeline is held the position catcher mark can occur again.
When the processing sleeved pipe, for example in the process of instlated tubular, inner and outer tubes need to weld together, there is the gap after the two pipe assemblings, lean on the artificial axiality that is difficult to guarantee inner and outer pipe during welding, and adopt tool locating efficient low, and can affect welding quality.
Summary of the invention
The above-mentioned technical problem that exists in order to overcome the prior art field, the purpose of this utility model is, provides a kind of pipe end automatic reducing diameter-setting equipment, simple and reasonable, reducing sizing efficient is high, effectively avoids steel tube surface catcher mark, cut to occur, guarantees tube quality.
The automatic reducing diameter-setting equipment of the pipe end that the utility model provides, it comprises hydraulic jack, mounting flange, movable push, slide block, slide block inner sleeve, sliding sleeve, module and pincers piece, described mounting flange is installed on the hydraulic jack, be provided with piston in the described hydraulic jack, movable push is connected with the piston rod of set piston, and described slide block is installed in the movable push top.Described slide block set is contained in the sliding sleeve, and described slide block inner sleeve is installed in the slide block, and the pincers piece is installed in the slide block inner sleeve.The inner chamber of described sliding sleeve is frustum, and the external surface shape that described slide block contacts with sliding sleeve is frustum.Described module is installed in the centre of slide block, the below of slide block inner sleeve.The intracavity section of described slide block inner sleeve and slide block is stepped.Several guiding feather keys evenly are installed on the described movable push.Also be provided with spring between described slide block and the movable push.
The automatic reducing diameter-setting equipment of the pipe end that the utility model provides, its beneficial effect is, slide block set is set to be contained in the sliding sleeve, the inner chamber of sliding sleeve is frustum, the external surface shape that described slide block contacts with sliding sleeve is frustum, effectively avoid the fit-up gap of slide block and sliding sleeve excessive, avoid in process, occurring moving axially, effectively guaranteed crudy; The intracavity section of slide block inner sleeve and slide block is stepped, the process requirements of the steel pipe of to satisfy effectively different tube diameters; Registration, to satisfy effectively are accurately located processing request, and sleeve pipe adds the gap that also can effectively eliminate man-hour between two pipes, make the coaxial assembling of two pipes.
Description of drawings
Fig. 1 is the overall structure schematic diagram of an embodiment of the utility model.
Mark among the figure:
