Abstract

The utility model discloses a kind of RFC draw bar with sand cleaning hole, it comprises hook tail end sphere and shaft, described hook tail end sphere is provided with hook uropore, the bottom of described shaft is with the line of centers of described shaft longitudinal direction for axle both sides are evenly equipped with sand cleaning hole, and the width between centers of described sand cleaning hole is 1/2nd of described shaft length.The RFC draw bar of what the utility model provided have sand cleaning hole, compare with existing RFC draw bar, when original auxiliary hole is constant, two sand cleaning holes are set up in the bottom of shaft, by the effect of this sand cleaning hole, the circulation efficiency of draw bar can be made to increase, simultaneously, sand removal is more thorough, for the processing of follow-up draw bar is given security.

Description

A kind of RFC draw bar with sand cleaning hole

Technical field

The utility model relates to a kind of goods train draw bar technical field, particularly relates to a kind of RFC draw bar with sand cleaning hole being used in railway truck and connecting.

Background technology

At present, traditional RFC draw bar adopts sodium silicate sand foundry technique, because RFC draw bar shaft only has 5 smaller auxiliary holes as shown in rear Fig. 1-2, adopt this foundry technique, the sand removal operation of product circulation is more difficult, the efficiency of impact circulation, thus the time making the sand removal of draw bar shaft spend on the whole is longer, and, if halfway words removed by the glass thread in shaft, also affect and follow-up thick accurately machined efficiency is carried out to foundry goods, therefore, there is provided a kind of can improve draw bar circulation efficiency and the RFC draw bar that sand removal has sand cleaning hole thoroughly have very important significance.

Utility model content

The utility model in order to the auxiliary hole of RFC draw bar shaft solving prior art and exist less, the technical matters of sand removal difficulty impact circulation efficiency, provides a kind of and can improve draw bar circulation efficiency and sand removal has the RFC draw bar of sand cleaning hole thoroughly.

For achieving the above object, the technical scheme that the utility model adopts is as follows:

A kind of RFC draw bar with sand cleaning hole, it comprises hook tail end sphere and shaft, described hook tail end sphere is provided with hook uropore, the bottom of described shaft is with the line of centers of described shaft longitudinal direction for axle both sides are evenly equipped with sand cleaning hole, and the width between centers of described sand cleaning hole is 1/2nd of described shaft length.

Further, described sand cleaning hole is oval through hole.

The RFC draw bar of what the utility model provided have sand cleaning hole, compare with existing RFC draw bar, when original auxiliary hole is constant, two sand cleaning holes are set up in the bottom of shaft, by the effect of this sand cleaning hole, the circulation efficiency of draw bar can be made to increase, simultaneously, sand removal is more thorough, for the processing of follow-up draw bar is given security.

Fig. 4 is the utility model draw bar birds-eye view;

In figure: 1-hook tail end sphere; 2-shaft; 3-hook uropore; 4-sand cleaning hole.

Specific embodiment

As shown in Figure 3-4, a kind of RFC draw bar with sand cleaning hole of the present utility model, comprise hook tail end sphere 1 and shaft 2, hook tail end sphere 1 is provided with hook uropore 3, the bottom of shaft 2 with the line of centers of shaft longitudinal direction for axle both sides are evenly equipped with sand cleaning hole 4, the width between centers of sand cleaning hole 4 is 1/2nd of shaft length, and sand cleaning hole is oval through hole.

Be existing RFC draw bar as shown in Figure 1-2, existing draw bar itself has auxiliary hole, but this auxiliary hole can not meet the requirement of product circulation sand removal well, and the utility model has made structural improvement on the basis of existing technology, newly-increased two sand cleaning holes in the bottom of shaft, this sand cleaning hole can improve the circulation sand removal efficiency of product, also makes sand removal in shaft more thorough, for the thick fine limit work of follow-up draw bar provides failure-free to ensure simultaneously.

Protection domain of the present utility model is not limited thereto, and is anyly familiar with those skilled in the art in the technical scope that the utility model discloses, the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should define with claim is as the criterion.

Claims

1. one kind has the RFC draw bar of sand cleaning hole, it comprises hook tail end sphere and shaft, described hook tail end sphere is provided with hook uropore, it is characterized in that: the bottom of described shaft is with the line of centers of described shaft longitudinal direction for axle both sides are evenly equipped with sand cleaning hole, and the width between centers of described sand cleaning hole is 1/2nd of described shaft length.

2. a kind of RFC draw bar with sand cleaning hole as claimed in claim 1, is characterized in that: described sand cleaning hole is oval through hole.
