的に交換できる装置の出現が要望されていた。 Conventionally, when replacing the entrance guide or pusher head, you would lift the previously used entrance guide and pusher head with an overhead crane and move them to another location, and then lift the new entrance guide and pusher head with a crane and move them to the rolling mill. It was a compromise. For this reason, replacement requires a lot of manpower and time, and there are problems such as not being able to use a crane for other work during replacement, and there has been a desire for a device that can automatically replace these items in a short time.

In the figure, reference numeral 1 denotes a hollow cylindrical entrance guide, and an enlarged diameter portion 11 is provided at the rear end. As shown in FIG. 3, this entrance guide 1 is equipped with guide plates 12 and 13 on both sides that are fitted into grooves 21 and 22 provided in the main body 2, and the cutout portions of the guide plates 12 and 13 are engaged with each other. The engaging element 15 is fixed with a shaft, and one end of the engaging element 15 has a protruding portion facing a hole 14 provided in the entrance guide 1. Stators 23 and 24 are fixed to the main body 2, and one end thereof is connected to operating rods 27 and 28 of hydraulic cylinders 25 and 26 fixed to the main body 2, respectively (see FIG. 1). In addition, in FIG. 3, only one side of the engaging element 15 and the stator 24 are shown.

It is configured to open on the side. 6 is a pusher head connected to rod 63, 61, 62
is the tsuba installed at the back. Note that a groove may be provided in place of the collar. This pusher head 6 is the fourth
The rod 6 is driven by a chain 64 as shown in the figure.
3, it moves forward and backward along the axis. At this rearward end position, there is provided a movable table 71 on which at least one set of pusher head 6 with entrance guide 1 locked together with rod 63 can be placed. Note that a hydraulic device may be used instead of the chain.

Ｒへ送り込む。 The billet feeding process using the apparatus constructed as described above will be explained as follows. When the heated billet 4 is fed into the charging machine 3, the guide cover 5 is opened, and when the billet 4 is loaded, the guide cover is closed again. At this time, the pusher head 6 is driven by the chain 64 and moves forward, pushing the billet 4 into the entrance guide 1 and feeding it between the rolling rollers R. When the billet 4 is fed into the rolling roller R, the pusher head 6 is driven in the opposite direction by the chain 64 and retreats.
Return to the original position again. By repeating such an operation, billets 4 are sent one after another from the entrance guide 1 to the rolling roller R.

時係止したり解除できることは云うまでもない。 Next, when replacing the entrance guide 1 and the pusher head 6, the pusher head 6 is advanced and fitted into the entrance guide 1 as shown in FIG. 3a. Next, when the hydraulic cylinder 26 is operated to rotate the stator 24 counterclockwise around the shaft, b
As shown in the figure, the stator 24 pushes the engaging element 15 to rotate it counterclockwise, inserts the protrusion at the tip through the hole 14 of the entrance guide 1 between the flanges 61 and 62 of the pusher head 6, and then 6 to lock the entrance guide 1. The overall state at this time is shown in FIG. 4b. When the pusher head 6 is moved backward in this state, the entrance guide 1 and the pusher head 6 are moved back together as shown in FIG. 4c. At this time, the stator 24 is returned to the state shown in FIG. 3a. When the entrance guide 1 and the pusher head 6 are further retreated, the rod 63 is sent to the moving table 71 provided on the base 7, as shown in FIGS. 4d and 5, and the rod 63 is removed from the chain 64. In addition,
It goes without saying that the pusher head 6 and the entrance guide 1 can be locked or unlocked arbitrarily and at any time.

台７１に戻す。 The moving table 71 includes a motor and a hydraulic system (not shown).
etc., so that it can be moved left and right (up and down in the figure) on the base 7. Also, on the movable base 71 are entrance guides 1a, 1b, 1c and pusher heads, each having the same or different outer diameter. 6a, 6
Since a combination of b and 6c is prepared,
Move the moving table 71 to attach the desired entrance guide and pusher head (for example, 1b and 6b) to the chain 64.
Align with the position of Next, when the rod 63b is pushed out by the hydraulic cylinder 72, the rod 63b engages with the chain 64 and moves forward. When the entrance guide 1b is sent into the predetermined position of the main body 2, the engager 15b
becomes a neutral state and rotates clockwise, and the tsuba 61
b, 62b is released. At this time, if the pusher head 6b is retreated, the entrance guide 1b is left behind on the main body 2 and is attached to it.
Note that, as shown in FIG. 3a, the expanded diameter portion 11 of the entrance guide 1 is prevented from moving forward by the stator 24, so even if the billet 4 moves forward while contacting the inner peripheral surface, it will not remain in that position. Retained. When replacing only the pusher head 6, it is sufficient to prepare a pusher head 6 without the entrance guide 1 mounted on the moving table 71. In that case, the pusher head 6 in use is returned to the movable table 71 without engaging the entrance guide.

で、実施による効果は顕著である。 As detailed above, according to the present invention, the entrance guide and the pusher head can be replaced simultaneously and automatically, so there is no need to use an overhead crane for replacement, and the replacement time can be significantly shortened. The effects of implementation are significant, as no human resources are required for this purpose.
