Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic core stacking and aligning device that stacks and aligns thin plate cores punched by a press machine to form a magnetic core.

(Prior Art) Conventionally, as a method of forming a magnetic core with a laminated plate, a long sheet material is conveyed to a pressing device and press-punched to form a thin core plate, and then this thin core plate is used as a parts feeder. It is carried out that the laminated core is formed by feeding and aligning the layers, and then fixing and laminating every predetermined number of sheets by laser welding or the like.

(Problems to be Solved by the Invention) However, in the conventional method as described above, after performing the press punching, the thin core plates are once aligned through the parts feeder, and therefore, there are the following problems.

(1) As described above, at least the pressing step and the step of aligning the thin core plates through the parts feeder
A process is required.

(2) When the thin core plate is put on the parts feeder after the press punching, a washing process is required to remove the punching oil adhered during the pressing.

(3) The thin core plate punched in the ball of the parts feeder may be entangled and deformed.

(4) When the thin core plate passes through the parts feeder, the parts may be caught on the side plates of the parts feeder, and thus it is necessary to manually restore the parts.

Therefore, a stacking alignment device has been proposed in which the press bolster is penetrated and the work is directly sent from the press die to the alignment chute. However, there are the following problems here. That is, normally, the work alignment accuracy (stacking deviation) on the chute is ensured by reducing the clearance between the work and the chute and the die can be connected with high accuracy and smoothly. The work needs to be sent from the die to the chute. Further, in the pressing device used here, it is necessary to replace the die and the chute according to the shape and size of the work, so the positioning between the chute and the die during the replacement work is
Often becomes an important task in work.

The present invention has been made based on the above circumstances. When the work is sent from the press punching die to the alignment chute, the work can be smoothly sent out, and the clearance between the work on the alignment chute and the alignment accuracy can be reduced. It is an object of the present invention to provide a stacking and aligning device for press-punched parts, which is devised so as to maintain high stacking accuracy).

(Means for Solving the Problems) In order to solve the above-mentioned problems, in the present invention, the press-cut parts can be housed in series in the extraction direction of the press-cut parts that are press-punched from the die of the press-cut die. In a stacking and aligning apparatus for press-punched parts, which connects an alignment chute and sequentially feeds the drawn-out parts extracted from the die into the alignment chute and stacks them, the die is passed through a press bolster of the press-cutting die, and the die And a relay unit for connecting the alignment chute to the relay chute.

(Operation) With this relay unit, the die and the alignment chute can be easily and accurately aligned. For this reason,
In the process of manufacturing highly accurate parts, it is possible to continuously realize alignment without any misalignment in the delivery from the press die.

In the present invention, an alignment chute is used to stack the press-punched parts that have been press-punched, but a jig such as a rail having a function corresponding to this alignment chute can be provided outside.

(Example) Hereinafter, the Example of this invention is described, referring drawings.

FIG. 1 is a longitudinal sectional view showing an embodiment of a magnetic core stacking and aligning apparatus of the present invention.

In the press die in the figure, 2 is an upper die set, 3 is an upper packing plate, 4 is a punch plate, 5 is a punch for punching, 6 is a stripper plate, 7 is a die plate, and 8 is a lower die. A packing plate, 9 is a lower die set, and 17 is a guide post of the die set. Further, 10 is a horizontal press machine, 11 is a press ram of the horizontal press machine 10, and 12 is a press bolster of the horizontal press machine.

In the above structure, a long sheet material is inserted between the stripper plate 6 and the die plate 7, and the pressing device 10
By driving the press ram 11 to press the press ram 11, the press-punched part 1 conforming to the shape of the die is formed. When press punching is sequentially performed by this press punching die, the already punched press punching parts 1 exit the die plate 7 in the stacked state and enter the lower die packing plate 8.

Further, in the present embodiment, the inner diameter of the lower die packing plate 8 is similar to that of the press-cut component 1 and is the same as that of the die-side plate 7 on the outlet side. A relay unit 15 to be described later is formed on the outlet side of the lower mold packing plate 8 so as to have a clearance large enough to maintain the state.
A chute 13 having an inner diameter approximately the same as the inner diameter of the lower mold packing plate is disposed through the. The inner diameter of the lower die packing plate 8 and the inner diameter of the chute 13 are continuously connected. The chute 13 is fixed by a chute mounting base 14, and the chute 13 and the inner diameter of the lower mold packing plate 8 are fixed.
The inner diameters of are connected to form a continuous passage.

In such an apparatus of this embodiment, the part punched into the die plate of the press punching die is extruded by the thickness of the next punched part in the exit direction of the die plate 7, and the chute through the relay unit 15. It is sent in sequence while keeping the state of being stacked and aligned in 13. And shoot
When the press-punched part 1 in 13 is full, the chute is removed and replaced with an empty chute, and the same press-punching and stacking alignment is performed again.

In this embodiment, the relay unit 15, the lower packing plate 8 and the chute 13 all have the same inner diameter and form continuous passages.

Generally, since the lower die set and the press bolster 12 have a considerable thickness, it is considerably troublesome to directly dispose the chute 13 on the lower packing plate 8.
Therefore, the workability of exchanging the chute can be improved by providing the relay unit 15 as described above.

(Effects of the Invention) The present invention has been described in detail above, and an alignment chute capable of accommodating the press-cut parts in series is connected in the extraction direction of the press-cut parts that are press-pressed from the press-cut die. In a stacking and aligning device for a press-cutting component for sequentially sending out the drawing-out components extracted from the die into the aligning chute and stacking and aligning the components, the die and the aligning chute are passed through the press bolster of the press-cutting die. Since the relay unit for connecting the dies is provided, the alignment between the die and the alignment chute can be easily and accurately realized by the relay unit. For this reason, in the process of manufacturing highly accurate parts, there is an excellent effect that there is no hindrance to the delivery from the press die and the continuous alignment without stacking deviation can be realized.
