Abstract
The utility model discloses a kind of forging horse rod, comprise cylindrical body (1), the middle part of one end of described body (1) is provided with step (2), body (1) is divided into the excellent body A section (3) of different-diameter and excellent body B section (4) by described step (2), and the diameter of described excellent body A section (3) is greater than the diameter of described excellent body B section (4).The utility model has structure advantage simple, easy to use, with low cost, adopt it can when not needing more to change person rod, repeatedly carry out reaming, decrease operation, save the time, reduced production cost, simultaneously, prevent the appearance of wall unevenness and horn mouth defect, improve product quality.
Description
Technical field
The utility model relates to a kind of forging horse rod.
Background technology
At present, conventional open die forging circle series products is all carry out reaming by horse rod, increases endoporus and reaches dimensional requirement.In order to control endoporus circularity, changing different directly horse rod by needs and carrying out expanding treatment, doing not only adding operation like this, delayed the time, and in the process of continuous reaming, each pressure degree of depth differs, cause wall unevenness or horn mouth, finally cause scrapping of product.
Utility model content
The purpose of this utility model is just to provide a kind of forging horse rod that can reduce replacing operation.
The purpose of this utility model is realized by such technical scheme, a kind of forging horse rod, comprise cylindrical body, the middle part of one end of described body is provided with step, body is divided into the excellent body A section of different-diameter and excellent body B section by described step, and the diameter of described excellent body A section is greater than the diameter of described excellent body B section.
In order to improve the circularity in hole, described excellent body B section is positioned at the centring ring being provided with evagination in the middle part of excellent body B section.
In order to improve radiating efficiency, in described body, be provided with the louvre running through body.
Owing to have employed technique scheme, the utility model has structure advantage simple, easy to use, with low cost, adopt it can when not needing more to change person rod, repeatedly carry out reaming, decrease operation, save the time, reduce production cost, meanwhile, prevent the appearance of wall unevenness and horn mouth defect, improve product quality.
Accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail; but the utility model is not limited to these embodiments; any improvement or alternative on the present embodiment essence spirit, still belongs to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, a forging horse rod, comprises cylindrical body 1, the middle part of one end of described body 1 is provided with step 2, body 1 is divided into the excellent body A section 3 of different-diameter and excellent body B section 4 by described step 2, and the diameter of described excellent body A section 3 is greater than the diameter of described excellent body B section 4.
In the utility model, by the excellent body of two sections of different-diameters, first reaming can be carried out in excellent body A3 section, then direct in the reaming of excellent body B section 4, eliminate the replacing operation of horse rod.
Further, described excellent body B section 4 is positioned at the centring ring 5 being provided with evagination in the middle part of excellent body B section 4.Centring ring 5 can make product as much as possible vertically put, and each drafts can compare with centring ring, more intuitively, makes product not easily occur bell-mouthed defect.
Further, in described body 1, be provided with the louvre 6 running through body 1.The temperature of body can be reduced by louvre 6, prevent distortion, increase the service life.
Claims (3)
1. a forging horse rod, comprise cylindrical body (1), it is characterized in that: the middle part of one end of described body (1) is provided with step (2), body (1) is divided into the excellent body A section (3) of different-diameter and excellent body B section (4) by described step (2), and the diameter of described excellent body A section (3) is greater than the diameter of described excellent body B section (4).
2. forging as claimed in claim 1 horse rod, is characterized in that: upper and be positioned at the centring ring (5) that excellent body B section (4) middle part is provided with evagination described excellent body B section (4).
