Description
Technical field：
It the utility model is related to a kind of new forging hook tail frame.
Background technology：
Couple yoke is the pith of coupler draft gear, is installation from plate, buffer and bears rail vehicle tractive force
Critical component, the pressure that carries is excessive when existing couple yoke is due to operation, it will usually which it is short service life occur, often changes and leads
Cause cost increase.
Utility model content：
The utility model is to provide a kind of new forging hook tail frame to solve the above-mentioned problems of the prior art.
There is technical scheme used by the utility model：A kind of new forging hook tail frame, including be integrally formed by forging
Framework and connecting plate, the connecting plate be placed in the head of framework；
The framework is U-shape, including two sides and a base；
Each side of framework includes integrally formed wide width portion and narrow wall part, passes through circle between wide width portion and narrow wall part
Cambered surface transition, the base of framework are placed between two narrow wall parts, and connecting plate is connected on wide width portion；
Thickened section is provided with the inwall of wide width portion, is provided with connecting hole on wide width portion, the connecting hole is through thickened section；
The length direction of the connecting plate is parallel with connecting hole axial direction.
Further, font tags are equipped with the base of the connecting plate and framework.
Further, the hook tail frame body is made of 25MnCrNiMoA steel billets.
The utility model has the advantages that：Framework and connecting plate in the utility model are integrally formed, and intensity is high,
Thickened section is set up in connecting hole, the carrying pressure of couple yoke can be strengthened.
Brief description of the drawings：
Fig. 1 is the utility model structure chart.
Embodiment：
The utility model is further described below in conjunction with the accompanying drawings.
As shown in figure 1, the utility model discloses a kind of new forging hook tail frame, including by forging integrally formed framework
1 and connecting plate 2, connecting plate 2 be placed in the head of framework 1.
Framework 1 in the utility model is U-shape, including two sides and a base.Each side Jun Bao of framework 1
Integrally formed wide width portion 11 and narrow wall part 12 are included, by the transition of arc surface 13 between wide width portion 11 and narrow wall part 12, framework 1
Base is placed between two narrow wall parts 12, and connecting plate 2 is connected on wide width portion 11.
Thickened section 14 is provided with the inwall of wide width portion 11, connecting hole 15 is provided with wide width portion 11, the connecting hole 15 passes through
It is through at thickened section 14.
The length direction of connecting plate 2 is parallel with the axial direction of connecting hole 15.
Font tags are equipped with the base of connecting plate 2 and framework 1.
The utility model hook tail frame body 1 is made of 25MnCrNiMoA steel billets.
The utility model sets up thickened section in connecting hole, and the carrying pressure born relative to the couple yoke of same level is big,
And framework 1 and connecting plate 2 are integrally formed by forging, intensity is high.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, some improvement can also be made on the premise of the utility model principle is not departed from, these improvement also should be regarded as
The scope of protection of the utility model.
