Detailed Description

The utility model will now be further described with reference to the accompanying drawings and detailed description.

As shown in fig. 1 to 7, a billet splitting apparatus may include a swivel stand 1, a shear pin 2, a hydraulic cylinder 3, and a plurality of (three shown) fixing posts 4. The rotary support 1 is a steel structural member and is of a box-type structure, so that the rotary support is not easy to deform under the heat radiation of a steel billet. The pivoting cradle 1 is rotatably mounted on a pivoting base 5 and suspended above a billet delivery roller 100. The swivel bracket 1 is provided with a first pin hole 11 at a middle position. The hydraulic cylinder 3 is fixed on the rotary base 5, and the telescopic rod thereof is hinged with the rotary bracket 1. A plurality of fixing posts 4 are erected at different positions below the slewing bracket 1 and provided with second pin holes 41. The hydraulic cylinder 3 drives the slewing bracket 1 to rotate to a required position, and the safety pin 2 passes through the first pin hole 11 and is inserted into the second pin hole 41 to fix the slewing bracket 1 at the position. Specifically, when the revolving rack 1 is stopped at the first working position, as shown in fig. 6, the billet 1# in this state goes to the upper side, and the billets 2# to 4# are guided to the lower side through the revolving rack 1; when the rotary support stops at the second working position, as shown in fig. 7, the billets 1# -3# in the state pass through the rotary support 1 to be guided to the upper side, and the billet 4# to be guided to the lower side, so that the guiding and the shunting of the billets are realized.

In order to facilitate the control of the rotation angle of the revolving support 1 (i.e. to stop the revolving support 1 at the corresponding station position), a displacement sensor (not shown) is provided in the hydraulic cylinder 4.

It should be understood that the hydraulic cylinder 3 may be replaced by other forms of drive mechanism (e.g., electric or pneumatic).

In the present embodiment, the slewing bracket 1 is mounted on a slewing pedestal 5 by a slewing mandrel 6. The upper end and the lower end of the rotary mandrel 6 are both provided with self-aligning roller bearings 7, and the self-aligning roller bearings 7 can bear radial load and also can bear certain axial load. Because the outer ring raceway is spherical, the centering performance is good, the coaxiality error can be compensated, and the centering device is suitable for the conditions of heavy load or impact load. Preferably, the revolving spindle 6 is a stepped shaft to facilitate the connection of the revolving support 1 and the revolving base 5. An oil cup 8 is arranged at the upper end of the rotary mandrel 6 and used for periodically filling lubricating grease to ensure the working performance of the bearing. In addition, be equipped with thrust ball bearing 9 between gyration dabber 6 and the rotating base 5, thrust ball bearing 9 can bear axial load, also has aligning performance, and the use of collocation aligning roller bearing 7 can reduce installation error's influence, is applicable to the lower condition of rotational speed.

Preferably, the end of the rotating bracket 1 is provided with a roller 12, and the roller 12 is supported on the rail 10 below the rotating bracket 1 in a rolling manner, so that a better supporting effect can be achieved and the rotating bracket 1 is prevented from deforming. The rails 10 are fixedly mounted on the respective rail brackets. In order to reduce the overall weight of the slewing bearing 1, the upper and lower plates of the slewing bearing 1 have a plurality of rectangular cutouts 13.

For the convenience of guiding, both sides of the tail part 14 of the rotating bracket 1 are inclined planes, that is, the tail part of the rotating bracket 1 is approximately wedge-shaped. Preferably, the tail end is rounded to avoid damaging the billet.
