Abstract
The utility model discloses a cold-drawn head which comprises a hydraulic part, wherein the hydraulic part comprises a hydraulic sleeve and a hydraulic pull rod; a cylindrical hollow connection sleeve is arranged on the top of the hydraulic sleeve; a cylindrical connection chapiter is arranged on each of two sides of the connection sleeve; a connection seat head is arranged on each connection chapiter. According to the cold-drawn head disclosed by the utility model, the connection seat heads on the two sides of the connection sleeve are used, so that a conventional single-point support is changed into a double-point support; and therefore, the stability and the reliability of the rotation of the hydraulic part are greatly improved, and the pipe blank drawing precision is further improved. The cold-drawn head is simple in structure, convenient to modify and high in practicability.
Description
Technical Field
The utility model relates to a tubulation equipment, more exactly, be a cold drawing pull head.
Background
Cold drawing is a common method for processing seamless steel pipes, and a cold drawing machine is used for drawing the steel pipes into preset sizes according to a die, so that the precision is high. The existing cold-drawing machine needs to clamp the end of a pipe blank in advance when drawing the pipe, the existing method is to use a hydraulically driven chuck, a hydraulic cylinder only can depend on a movable support at the bottom, and the hydraulic cylinder is poor in stability and easy to deflect due to the adoption of single-point support, so that the drawing precision is influenced.
Disclosure of Invention
The utility model mainly solves the technical problem existing in the prior art, thereby providing a cold-drawing pull head.
The above technical problem of the present invention can be solved by the following technical solutions:
the cold-drawing pull head comprises a hydraulic part, the hydraulic part comprises a hydraulic sleeve and a hydraulic pull rod, the top of the hydraulic sleeve is provided with a hollow cylindrical connecting sleeve, two sides of the connecting sleeve are respectively provided with a cylindrical connecting column head, and the connecting column heads are respectively provided with a connecting seat head.
As the embodiment of the utility model discloses the preferred, the middle part of connector head be equipped with a connect the via hole, the connection column cap run through respectively connect the via hole, the bottom of connector head be equipped with a square spacing outstanding.
As a preferred embodiment of the present invention, the connecting sleeve is detachably connected to the hydraulic sleeve.
The utility model discloses a cold drawing pull head utilizes the connector head of connecting sleeve both sides, changes current single-point support and supports for two points, has improved stability and reliability when hydraulic pressure portion rotates greatly, has further improved the precision that the pipe embryo was drawn. The cold-drawing pull head is simple in structure, convenient to transform and high in practicability.
