Description

Tool for frog alloy steel point rail drilling and positioning

Technical Field

The utility model relates to a track production processing technology, in particular to frock that is used for frog alloy steel point rail drilling location.

In the design and development process of the frog, the variety of the frog is gradually increased from single frog, from the prior massive use of high manganese steel integrally cast frog to the prior alloy steel point rail combined frog, and the like. In the production and manufacture of alloy steel point rail combined frog, the production and manufacture of the alloy steel point rail is a very important ring. The alloy steel point rail is made of special alloy steel materials through forging and pressing through heat treatment, so that the overall shape is already set during blank forming. The integral lines of the point rails are determined by the number of corresponding frog numbers, and the centrosymmetric shape characteristics make the alloy steel point rails more difficult to drill and position than other rail parts.

In the current frog production process, the method for drilling the alloy steel point rail is mainly manual marking. A worker uses marking tools such as a measuring tape, a long steel ruler, a scriber and the like to mark a drilled hole on the center rail according to a design drawing, and then the drilling machine is used for drilling the hole. And because the core rail is uneven, a plurality of steps are required when the core rail is placed on the scribing platform compared with other rail parts, and the tooling, the scribing plane and the like need to be manufactured in advance. In addition, the manual scribing method causes errors, and such errors increase when the number of the heart rails decreases or the length becomes long. Since the hole pitch and the hole position tolerance on the point rail are in mm, when manually marking lines in actual production, repeated checking is carried out to avoid errors, and the labor consumption is increased. If the drawing is not checked accurately or the drawing is wrongly scribed, the point rail is scrapped. In the drilling process of the point rail, the production mode not only increases the working difficulty for workers, but also improves the probability of raw material loss of products, and phase change increases the production cost of enterprises.

Therefore, in order to meet the requirement of accurate and quick positioning of the alloy steel point rail during drilling, the need of providing a novel positioning tool is very urgent.
