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 kind of tubulation apparatus, or rather, is a kind of cold-drawn pull head.
Background technology
Cold-drawn is a kind of common method of processing seamless steel pipe, utilizes drawbench that steel pipe is drawn into predetermined size according to mould, and precision is higher.Existing drawbench, in the time carrying out trombone slide, need to clamp the termination of pipe embryo in advance, and existing method is to utilize hydraulically powered chuck, ram pot can only rely on the travel(l)ing rest of bottom, owing to adopting single-point support, the less stable of ram pot, easily there is deflection, the precision that impact draws.
Summary of the invention
The utility model is mainly to solve the existing technical problem of prior art, thereby a kind of cold-drawn pull head is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of cold-drawn pull head, described cold-drawn pull head comprises a hydraulic pressure portion, described hydraulic pressure portion comprises a hydraulic-pressure sleeve and a hydraulic pressure draw-bar, the top of described hydraulic-pressure sleeve is provided with the branch sleeve of a hollow cylindraceous, the both sides of described branch sleeve are respectively equipped with a columned connection column cap, on described connection column cap, are respectively equipped with a connecting seat head.
As the utility model preferred embodiment, the middle part of described Connection Block head is provided with a connecting through hole, and described connection column cap runs through respectively described connecting through hole, and the bottom of described Connection Block head is provided with square spacing giving prominence to.
As the utility model preferred embodiment, described branch sleeve is removably connected with described hydraulic-pressure sleeve.
Cold-drawn pull head of the present utility model utilizes the Connection Block head of branch sleeve both sides, and changing existing single-point support is that two point supports, and has greatly improved stability and reliability when hydraulic pressure portion rotates, has further improved the precision that pipe embryo draws.This cold-drawn pull header structure is simple, and transformation is convenient, practical.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Wherein,
1, cold-drawn pull head; 2, hydraulic pressure portion; 21, hydraulic-pressure sleeve; 22, hydraulic pressure draw-bar; 23, branch sleeve; 24, connect column cap; 3, Connection Block head; 31, connecting through hole; 32, spacing outstanding.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
As shown in Figure 1 to Figure 3, cold-drawn pull head 1 of the present utility model comprises a hydraulic pressure portion 2, this hydraulic pressure portion 2 comprises a hydraulic-pressure sleeve 21 and a hydraulic pressure draw-bar 22, the top of this hydraulic-pressure sleeve 21 is provided with the branch sleeve 23 of a hollow cylindraceous, the both sides of this branch sleeve 23 are respectively equipped with a columned connection column cap 24, on this connection column cap 24, are respectively equipped with a connecting seat head 3.
The middle part of Connection Block head 3 is provided with a connecting through hole 31, connects column cap 24 and runs through respectively connecting through hole 31, and the bottom of Connection Block head 3 is provided with one square spacing outstanding 32.
This branch sleeve 23 is removably connected with this hydraulic-pressure sleeve 21.
The above, be only the specific embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
