Abstract

The utility model discloses a roller block of a cold Pilger mill. The circumferential surface of the roller block is equipped with at least two hole patterns changing along the specific curves. According to the technical scheme of the utility model, the circumferential surface of the roller block is equipped with at least two hole patterns and two matched roller blocks are arranged inside the same frame in an up-down manner. Since the roller block is equipped with at least two hole patterns, at least two pipes are rolled at a time, thereby improving the production efficiency. The problem that only one pipe is rolled at a time due to the conventional block equipped with only one hole pattern is solved, wherein the production efficiency is low.

Description

The roll piece of Pilger cold pilger mill

Technical field

The utility model relates to pressure processing machinery equipment technical field, more particularly, relates to a kind of roll piece of Pilger cold pilger mill.

Background technology

At present, the Pilger cold pilger mill is the single line machine, only processes the pass that a radius changes according to specific curves on the circumferencial direction of roll piece.Adopt this kind Pilger cold pilger mill rolled pipe period of the day from 11 p.m. to 1 a.m, pipe being rolled between two roll pieces up and down in being installed in same pair of frame, owing to have only a pass on the roll piece, thus at every turn can only a rolling pipe, production efficiency is low.

The utility model content

For solving the problems of the technologies described above, the utility model provides a kind of roll piece of Pilger cold pilger mill, has only a pass to solve in the prior art on the roll piece, at every turn can only a rolling pipe, cause the low problem of production efficiency.

The utility model provides a kind of roll piece of Pilger cold pilger mill, and the periphery of described roll piece is provided with the pass of at least two descending variations of radius.

Use technique scheme, the periphery of roll piece is provided with at least two passes, settle two roll pieces that are complementary up and down in the same pair of frame, because the roll piece is provided with at least two passes, so each rolled pipe period of the day from 11 p.m. to 1 a.m is rolling at least two pipes simultaneously, enhance productivity, and have solved and have had only a pass in the prior art on the roll piece, at every turn can only a rolling pipe, cause the low problem of production efficiency.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, the accompanying drawing that describes below only is some embodiment that put down in writing in the utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

The structural representation of the roll piece of the Pilger cold pilger mill that Fig. 1 provides for the utility model;

Fig. 2 is the A-A cutaway view among Fig. 1;

Fig. 3 is the another kind of cutaway view of the A-A among Fig. 1.

The specific embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills belong to protection domain of the present utility model not making the every other embodiment that is obtained under the creative work prerequisite.

The structural representation of the roll piece of the Pilger cold pilger mill that the utility model embodiment provides as shown in Figure 1.Wherein:

1 is roll mandrel, and 2 is the roll piece, and 3 is pass.

Roll piece 2 is installed on the roll mandrel 1, and its periphery is provided with two passes 3, this pass 3 changes according to specific curves, and for example: descending variation of the radius of pass 3 or radius change according to cosine curve, and perhaps the shape of pass 3 changes according to specific curves.

Because the pass 3 on the roll piece 2 increases to two by original one, so need do corresponding improvement to the associated components of existing Pilger single line cold pilger mill.For example: grade size of opening of frame is amplified to guarantee that the roll piece can be installed on the frame, and preceding dop, mandrel stem and feed screw all have one to increase to two.Certainly, may also need other associated components are done corresponding improvement, the utility model embodiment is no longer set forth this.Pilger single line cold pilger mill after the improvement is rolling two pipes simultaneously, enhance productivity.Existing two-wire pipe mill is rolling two pipes simultaneously, but present two-wire pipe mill cost height, and then cause rolling pipe cost to rise, and the Pilger single line cold pilger mill cost after improving is low with respect to existing two-wire pipe mill, has therefore reduced the cost of rolling pipe.In addition, low with existing two-wire pipe mill, the Pilger single line cold pilger mill structure after the improvement is simple relatively, easy to make.

Roll piece 2 among the utility model embodiment is annular roll piece, as shown in Figure 2.In order to guarantee machining accuracy, in pass 3 processes of processing roll piece 2, need two roll pieces 2 are processed simultaneously, identical with the variation of the pass 3 that guarantees both, thus guarantee that rolling tubular shape is identical, the precision height.

Certainly, the roll piece that the utility model provides can also adopt the roll piece of other shapes, shown in Fig. 3.Roll piece among Fig. 3 is semicircle roll piece, and its periphery is provided with two passes that change according to specific curves.Adopt semicircle roll piece also to need the associated components of existing Pilger single line cold pilger mill is done corresponding improvement.Equally, in order to guarantee precision, need process two semicircle roll pieces simultaneously.

Use technique scheme, the periphery of roll piece 2 is provided with two passes 3, settle two roll pieces 2 that are complementary up and down in the same pair of frame, because roll piece 2 is provided with two passes 3, so each rolled pipe period of the day from 11 p.m. to 1 a.m is rolling two pipes simultaneously, enhance productivity, and have solved and have had only a pass in the prior art on the roll piece, at every turn can only a rolling pipe, cause the low problem of production efficiency.

The utility model embodiment breaker roll piece 2 is provided with the situation of two passes 3, certainly, can also be provided with two on the roll piece 2 with epithyrid 3, enhances productivity.Be provided with two on the roll piece 2 during with epithyrid 3, two passes 3 are identical with being provided with, and the associated components of Pilger single line cold pilger mill also will be done corresponding improvement, and this utility model is no longer set forth this.

To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment is conspicuous to those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet and principle disclosed herein and the corresponding to wide region of features of novelty.

Claims

1. the roll piece of a Pilger cold pilger mill is characterized in that, the periphery of described roll piece is provided with the pass of at least two descending variations of radius.
