Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a workpiece take-out device in an aluminum forging heating furnace used to heat aluminum or aluminum alloy prior to forging.

[Prior Art] In an aluminum forging heating furnace, a horizontal gutter-shaped support is attached to a conveyor that passes through the heating furnace body, and workpieces placed in a row on the gutter-shaped support are sequentially taken out from the side.
It was dropped into a chute connected to a gutter-like receiver.

[Problems to be Solved by the Invention] In the conventional apparatus described above, a head must be provided between the gutter-shaped receiver and the chute, so that the workpiece is easily damaged. Additionally, it was necessary to secure a space to the side of the heating furnace as a location for the chute. Furthermore, since the chute is provided through the extraction window hole provided in the furnace wall, the chute must be heat resistant, and it is not possible to use a chute that allows the workpiece to be easily moved and is not easily damaged.

This invention aims to prevent damage to the workpiece by eliminating the need to drop the workpiece when transferring it from the trough-shaped receiver to the chute, and to facilitate placement of the chute.

[Means for solving problems] This will be explained with reference to the drawings.

In the workpiece take-out device for an aluminum forging heating furnace according to this invention, a conveyor 11 passing through a heating furnace main body 10 is equipped with a horizontal gutter-shaped support 12, and works 13 are arranged in a row on the gutter-like support 12. In an aluminum forging heating furnace configured to sequentially take out the metal from the lateral direction, a cart 15 that advances and retreats toward the removal window hole 14 provided in the furnace wall is provided, and a vertical support is provided at the forward end of the forward-direction overhang 16 of the cart 15. A transfer plate 18 that is rotatable around a shaft 17 is installed, and in the forward position A of the trolley 15, the transfer plate 18 is connected to the gutter-shaped support 12, and in the retreat position B, the workpiece 13 on the transfer plate 18 is connected.
A pusher mechanism 20 is provided for pushing out onto the chute 19, and also contacts the transfer plate 18 during each forward and backward movement of the trolley 15 to rotate the transfer plate 18 forward and reverse by a predetermined angle about its vertical support shaft 17. A guide piece 21 is provided.

[Example] This will be explained with reference to the drawings.

10 is a heating furnace body for aluminum forging. 11 is a conveyor passing through the heating furnace main body 10, and 12 is a horizontal gutter-shaped support 12 attached to the conveyor 11. 13 are workpieces arranged on the gutter-shaped support 12;
8 is a workpiece extrusion device that pushes the workpiece 1 on the gutter-shaped receiver 12.
3 are sent to the next process one by one according to commands from the control device 30. Reference numeral 14 denotes an extraction window hole provided in the furnace wall. Reference numeral 22 indicates a rail arranged slightly below the extraction window hole 14, and 15 indicates a trolley placed on the rail 22. The expansion and contraction of the fluid cylinder 23 is carried out by the trolley 1 via a chain 24 and a chain wheel 25.
5 is designed to move forward and backward. A projecting portion 16 is provided in the forward direction of the truck 15, and a vertical support shaft 17 is provided at the tip of the projecting portion 16. Reference numeral 18 denotes a transfer plate rotatably installed around the vertical support shaft 17.

In the forward position A of the truck 15, the transfer plate 18 is connected to the gutter-shaped receiver 12, and in the backward position B, a pusher mechanism 20 is provided that pushes the workpiece 13 on the transfer plate 18 onto the chute 19.

Furthermore, a guide piece 21 is provided which contacts the transfer plate 18 during each forward and backward movement of the truck 15 and rotates the transfer plate 18 forward and reverse by a predetermined angle about its vertical support shaft 17.

[Operation] The non-operating state is when the truck 15 is in the retreated position B.

First, in this non-operating state, when the fluid cylinder 23 begins to contract, the truck 15 begins to move forward via the chain 24 and chain wheel 25. When passing through the guide piece 21, the transfer plate 18 rotates so that its socket 26 faces the outlet 27 of the trough-shaped support 12, as shown in FIGS. 4 to 7. The transfer plate 18 together with the overhanging part 16 has a window hole 1 for taking out.
4 and enters the heating furnace main body 10, and transfer plate 18
A socket 26 connects to an outlet 27 of the trough-like receiver 12 .

Next, the work extrusion device 28 moves to move one workpiece 13 on the trough-like receiver 12 onto the transfer tray 18.

Next, the trolley 15 begins to move backwards, and the transfer plate 18
When passing through the guide piece 21, FIGS. 8 to 11
As shown in the figure, it rotates to the D state and returns to position A.

Further, the pusher mechanism 20 is extended,
The work 13 on the transfer plate 18 is moved onto the chute 19.

Finally, the pusher mechanism 20 retracts and returns to its initial state.

[Effect of the invention] The workpiece 1 is placed on the transfer plate 18 at the outlet 27 of the trough-shaped receiver.
3, move the trolley 15 backward, and transfer the tray 1.
8 around the vertical support shaft 17 to attach the chute 1.
I moved it to point 9 and then sent it out onto chute 19. Therefore, the position of the chute 19 relative to the outlet 27 of the trough-like receiver can be arbitrarily selected. In the conventional device, the outlet of the gutter-shaped support and the inlet of the chute had to be installed on a straight line, so the longitudinal direction E-E of the heating furnace body 10 and the chute were perpendicular to each other, and the installation space was reduced. It was often difficult to do so. This design has less disadvantage in terms of space.

In the conventional type, the gutter-shaped receiver was provided below to avoid the trajectory of the gutter-shaped receiver moving in the direction of movement of the conveyor, so that the workpiece would fall and ride on the chute. Therefore, there was a risk that the workpiece would be damaged. However, in this idea,
Since the transfer plate approaches and continues to approach the end of the trough-shaped receiver in a stopped state, it is possible to make the height of the trough-shaped receiver and the transfer plate the same, so that the workpiece is not damaged.

In the conventional type, the chute was inserted into the heating furnace main body through the extraction window, so only those with high heat resistance could be used. As a result, the chute does not slide smoothly, and transfer takes a long time, leading to the risk of the workpiece becoming cold or being scratched. However, in this invention, since the chute is not inserted into the heating furnace main body, it is possible to use a roller-incorporated chute with good sliding properties.

In addition, even if the overhanging part of the trolley and the transfer tray temporarily enter the heating furnace main body, they can be taken out of the heating furnace main body within a short time, so they can be used for practical purposes even if they are not made of high heat resistant materials. I can endure it.
