Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 2-5, fig. 2 is a schematic structural view of an embodiment of a coupler knuckle according to the present invention, fig. 3 is a sectional view of a junction between a coupler knuckle pin hole and a knuckle cavity, fig. 4 is a sectional view of a junction between a coupler knuckle pin hole and a knuckle cavity at another viewing angle, and fig. 5 is a sectional view of a tail cavity and a sand outlet.

As shown in fig. 2, the utility model provides a coupler knuckle, which comprises a head part 1, a tail part 2 and a neck part 3 connecting the head part and the tail part; the iron pushing action block 4 is connected with the head part 1 and the neck part 3, and is used for improving the structural strength of the iron pushing action block 4 and prolonging the service life of the iron pushing action block 4; the push iron action block 4 is formed with a push iron action surface 41 capable of acting with the knuckle push iron, and the push iron action surface 41 is an easy-to-draw surface.

The easy-to-draw surface is a structure which is opposite to a reverse-draw structure in the prior art, namely, a concave structure does not exist on the push iron acting surface 41 in the drawing direction, and during drawing, the push iron acting surface 41 does not interfere with the sand core in the drawing direction, so that the coupler knuckle and the die body can be conveniently and smoothly separated, and the casting quality of the coupler knuckle is ensured.

The iron pushing action surface 41 may be a plane, a curved surface, or a combination of a plane and a curved surface, which is a practical option.

In a specific scheme, the head part 1 of the coupler knuckle can comprise a columnar body 11 and a tongue body 12 connected with the body 11, the body 11 can be provided with a coupler knuckle pin hole 111, and in an assembly state, a coupler knuckle pin can penetrate through the coupler knuckle pin hole 111 to hinge the coupler knuckle and the coupler body; the body 11 may be connected to the neck 3 at its peripheral wall, and if the neck 3 is formed in a plate shape, the central axis of the knuckle pin hole 111 of the body 11 may be substantially perpendicular to the neck 3.

The iron pushing action surface 41, the peripheral wall of the body 11 and the axial end surface of the neck 3 in the knuckle pin hole 111 can be connected, and the connection part can be in smooth transition, so that the demoulding smoothness can be further improved.

Two configurations of the knuckle pin hole 111 provided in the body 11 are possible: firstly, only the coupler knuckle pin hole 111 is provided, at this time, the coupler knuckle pin hole 111 axially penetrates through the body 11, and the action length of the coupler knuckle pin hole 111 and the coupler knuckle pin is long; secondly, as shown in fig. 4, the knuckle pin hole 111 may be divided into two sections and connected through a pin hole inner cavity 112 in the body 11, and the radial dimension of the pin hole inner cavity 112 is larger than that of the knuckle pin hole 111, so that the matching of the knuckle pin and the knuckle pin hole 111 is not affected, and at the same time, by setting the shape of the pin hole inner cavity 112, the wall thickness of the body 11 may be controlled, and the acting length of the knuckle pin hole 111 and the knuckle pin may be changed.

For convenience of description, the knuckle pin hole 111 and the pin hole inner cavity 112 may be collectively referred to as a pin hole cavity, and in the prior art, the pin hole cavity is an independent cavity which is not communicated with the tongue cavity 121 arranged in the tongue body 12, which causes the pin hole cavity sand core and the tongue cavity sand core to be independent from each other during molding, and the relative positions of the pin hole cavity sand core and the tongue cavity sand core are easily shifted, thereby affecting the knuckle wall thickness between the pin hole cavity and the tongue cavity 121 and causing the casting quality of the knuckle to be poor.

To this end, as shown in fig. 3 and 4, in the embodiment of the present invention, the tongue cavity 121 may be communicated with the knuckle pin hole 111 or the pin hole cavity 112 (i.e. the pin hole cavity) by setting the communicating channel 13, and the pin hole cavity sand core and the tongue cavity sand core which are respectively set and independent of each other are combined into an integral core, so that the relative positions of the two sand cores may be determined, the positioning of the sand core may be optimized, and the relative positions of the tongue cavity 121 and the pin hole cavity in the casting process may be ensured, so as to improve the casting quality of the knuckle.

In addition, the communication channel 13 can provide more sand cleaning outlets for the tongue cavity 121, so that sand cores in the tongue cavity 121 can be discharged quickly.

It should be noted that, the embodiment of the present invention does not limit the number of the communication channels 13, and may be one or multiple; in a preferred embodiment, the communication channels 13 may be provided in plural, so that a plurality of connection points may be provided between the pin hole cavity sand core and the tongue cavity sand core, and the connection strength is higher, and when such a scheme is adopted, the communication channels 13 may be distributed at intervals along the axial direction of the knuckle pin hole 111.

Along the axial direction of the knuckle pin hole 111, the body 11 can be provided with impact platforms 113 on both sides of the neck 3, according to the position relationship in practical practice, the two impact platforms 113 can be respectively called as an upper impact platform and a lower impact platform, and the iron pushing action block 4 and the impact platform 113 on the same side can be connected to further improve the structural strength of the iron pushing action block 4.

Referring to fig. 5, a tail cavity 21 may be provided in the tail portion 2, the tail cavity 21 may be independent from or communicated with the pin hole cavity, and a sand outlet 22 communicated with the tail cavity 21 may be provided at the tail end (upper end in fig. 5) of the tail portion 2.

For convenience of description, the axial direction of the knuckle pin hole 111 may be referred to as a longitudinal direction, and a direction perpendicular to the longitudinal direction in a horizontal plane is a lateral direction. In the prior art, the sand outlet 22 is generally arranged at one side of the tail end of the tail part 2, which is deviated from the locking surface, so that the positioning of the coupler knuckle sand core is not facilitated, and the sand is not easy to be cleaned in the production process, and the process performance is poor.

To this end, as shown in fig. 5, in the embodiment of the present invention, the sand outlet 22 may be disposed in the transverse middle region of the tail end, which is favorable for positioning the coupler knuckle sand core during the core distribution process, and also facilitates sand cleaning, thereby improving the casting process performance.

The utility model also provides a car coupler, including coupler body and coupler knuckle, wherein, the coupler knuckle can be articulated with the coupler body, and the coupler knuckle is the coupler knuckle that each above-mentioned embodiment relates to.

The utility model also provides a railway vehicle, including a plurality of automobile bodies, each automobile body all is equipped with the coupling, and the coupling is the coupling that each embodiment of the aforesaid related.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
