Description

[Detailed description of the invention] The present invention consists of a heating furnace which is a long metal log hot cutting equipment for a metal extrusion press accessory, a hot billet shear, and a conveyor roll placed between them. This invention relates to a scrap discharge device in billet shed equipment.

In hot billet shed equipment, which consists of a conventional heating furnace, hot billet shed, and conveyor rolls,
When a long log with a certain length is cut into billets of the required length, the ends of the logs that are not cut to the required length remain in the fixed container. If this log is too short to be subjected to "over-extrusion" or if it is severely deformed by cutting, transport the next long log in the heating furnace and use its tip to move it out of the movable container. After the billet is ejected onto the billet support, it is released outside the machine by a separate device installed on the billet shaft, but depending on the length of the end and the degree of deformation, it may fall before being ejected. Each time this occurred, it had to be removed manually to restore normal operation.

The present invention eliminates the above-mentioned drawbacks of conventional equipment, increases the efficiency of linked operation with metal extrusion presses, and improves the productivity of the extrusion process. The objective is to obtain a log end discharge device.

Hereinafter, the present invention will be described with reference to Nos. 1 to 5 of the attached drawings showing one embodiment thereof.
This will be explained based on the diagram.

As shown in FIGS. 1 and 2, a lower frame 3 is provided with a large number of transport rolls 2 that are rotatably driven to transport the logs between the outlet of the long metal log heating furnace 1 and the hot billet shear body 30. An upper frame 6 is installed above the lower frame 3, and is installed above the lower frame 3, and is provided with a large number of pinch rolls 5 which are installed on the floor by supports 4 and are rotatably driven to transport logs in cooperation with the transport rolls 2. The roll 5 is configured to be able to press down the long log between the roll 5 and the transport roll 2 by lowering the upper frame 6 using a pneumatic or hydraulic cylinder (not shown).

Note that both the conveyance roll 2 and the pinch roll 5 are driven in forward and reverse directions by an electric motor.

In addition to this, as shown in FIGS. 1 and 3, the lower frame 3 is placed between the lower frame 3 and the hot billet shaft body 30. A swing frame 10 is provided on the same horizontal plane as the swing frame 10, and several free rolls 11 that are not driven are mounted on the bearing 1.
It is rotatably supported via 2.

In this case, the spacing between the free rolls 11 and the conveyor rolls 3 is made as small as possible.

Also, on the swing frame 10, there is a
A support frame 16 is provided with a pair of brackets 13 installed on the floor through a pair of pins 14 and brackets 15 in a direction perpendicular to the axis of the free roll 11.
It is attached so that it can be rotated at right angles to the direction in which the log travels.

Further, a bracket 17 is provided on the lower surface of the other side of the swing frame 10, and is connected to a piston of a hydraulically or pneumatically operated discharge cylinder 20 via a pin 18 and a metal fitting 19 provided parallel to the pin 14. The end of 20 is connected to the support frame 1 via a pin 21 and a bracket 22.
Mounted on 6.

Furthermore, in the present invention, the hot billet tanker main body 30, which was conventionally vertical, is placed horizontally, and as shown in FIGS. A fixed frame 31 is provided in the perpendicular direction, and a movable frame l that slides on the fixed frame 31 comes into contact with the side opposite to the swing frame of the fixed frame 310.
, 33 are installed on the fixed frame 31, and the fixed container 32 is placed concentrically with the log moving on the swing frame 10.
A hydraulic cylinder 36 is installed on one side of the fixed frame 31 to connect and slide the movable frame 33 with a piston, and on the other side is a hydraulic cylinder 36 for moving the movable frame 33 with a piston. A cylinder 38 to which a push plate 37 is attached is attached to the side opposite to the movable frame 33.

Furthermore, when the movable frame 33 is pulled to one side, a movable container 34 of the same diameter is fixedly provided concentrically with the fixed container 32, and the movable container 34 is fixedly provided at the bottom of the inner diameter part of the movable frame 33. A billet support 35 having an upper surface of the same height or lower is fixedly provided on the extrusion side of the billet, and furthermore, when the movable frame 33 is pushed to the other side, the billet support 35 is attached to the fixed container 32 concentrically with the fixed container 32. A push plate 3 is placed at the tip of the piston that operates toward the
9 is provided on the side opposite to the fixed frame.

Note that the cylinder 38 is configured to be concentric with the movable container 34 when the movable frame 33 is pushed toward the other side.

In this case, the distance between the centers of both containers 32, 34 and billet ejecting cylinder 38 and both containers 32.
The center-to-center distance between 34 and the end pushing cylinder 40 is
Both are assumed to be equal to the stroke of the hydraulic cylinder 36 for the shaft.

The present invention has the above configuration, and its operation will be explained next.

When the long log 50 carried out from the heating furnace 1 is sent onto the conveyor roll 2, as shown in FIG. 3, the upper frame 6 of the pinch roll 5 is lowered via a hydraulic or pneumatic cylinder. The log 50 is lowered by rolling both rolls 2 and 5.
Press between the conveyor roll 2 and the pinch roll 5.
are driven together, the long log 50 is fed into the hot billet shear main body 30 via the free roll 11 on the swing frame 10 and is twisted, and is stopped by an attached stopper (not shown).

Next, when the shaft hydraulic cylinder 36 is operated, the fixed container 32 and the movable container 34 cut the fixed-length billet 51 from the long log 50, and the movable frame 33
As the billet moves, the billet is placed on the billet support 35 and sent to the position of the billet ejection cylinder 38 provided on the fixed frame 31, and is ejected onto the billet support 35 by the push plate 37, and the state shown in FIG. The cut billet 51 is fed into a metal extrusion press by suitable equipment.

The uncut long logs are normally returned to the heating furnace 1 by reversing the conveyor rolls 2 and pinch rolls 5, and the movable container 34 is moved to the furnace by a hydraulic cylinder 36.
returns to its original state.

After repeating this cycle several times, if the end portion 52 has become short or has been greatly deformed due to cutting, and it becomes impossible to transport it to the heating furnace 1, the fourth As shown in the figure, the end pushing cylinder 40 provided on the movable frame 33 is operated, and the end 52 is pushed back onto the free roll 11 by its push plate 39.

Subsequently, as shown in FIG. 5, after the pinch roll 5 is raised via the upper frame 6 which is raised by a hydraulic or pneumatic cylinder, the release cylinder 20 is activated and the swing frame 10 is moved around the pin 14. The end portion 52 is released from above the free roll 11.

Since the present invention has the above-described structure and function, it is possible to automatically and reliably process the uncut ends of long logs, which was done manually in conventional hot billet shed equipment. Therefore, in conjunction with a metal extrusion press, continuous operation is possible without reducing its operating rate, and the productivity of the extrusion process can also be increased.

In addition, both ends of long logs made by casting have many defects, which can lead to a deterioration in the quality of the extruded product. It is also possible to process it in advance.
