Abstract
The invention discloses a kind of new forging hook tail frame, including by forging integrally formed framework and connecting plate, the connecting plate is 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, is placed between wide width portion and narrow wall part by arc surface transition, the base of framework between two narrow wall parts, 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.Framework and connecting plate in the present invention are integrally formed, and intensity is high, sets up thickened section in connecting hole, can strengthen the carrying pressure of couple yoke.
Description
Technical field：
The present invention relates 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.
The content of the invention：
The present invention is to provide a kind of new forging hook tail frame to solve the above-mentioned problems of the prior art.
The technical solution adopted in the present invention has：A kind of new forging hook tail frame, including by forging integrally formed frame
Body and connecting plate, the connecting plate are 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 present invention has the advantages that：Framework and connecting plate in the present invention are integrally formed, and intensity is high, in connecting hole
Thickened section is set up, the carrying pressure of couple yoke can be strengthened.
Brief description of the drawings：
Fig. 1 is structure chart of the present invention.
Embodiment：
The present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in figure 1, the present invention discloses a kind of new forging hook tail frame, including by forging the integrally formed He of framework 1
Connecting plate 2, connecting plate 2 are placed in the head of framework 1.
Framework 1 in the present invention is U-shape, including two sides and a base.Each side of framework 1 includes one
Body formed wide width portion 11 and narrow wall part 12, passes through the transition of arc surface 13, the base of framework 1 between wide width portion 11 and narrow wall part 12
It is placed between two narrow wall parts 12, 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.
Hook tail frame body 1 of the present invention is made of 25MnCrNiMoA steel billets.
The present invention sets up thickened section in connecting hole, and the carrying pressure born relative to the couple yoke of same level is big, and frame
Body 1 and connecting plate 2 are integrally formed by forging, and intensity is high.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, some improvement can also be made under the premise without departing from the principles of the invention, and these improvement also should be regarded as the present invention's
Protection domain.
