Description

[Detailed Description of the Invention] [Structure of the Invention] (Field of Industrial Application) The present invention relates to an improvement of a workpiece take-out device in a transfer press.

(Prior art) Generally, a transfer press device is one of the devices that realizes a press processing process that is highly automated and has high productivity. finger 1
and a pair of synchronously operated feed bars 2 to which the fingers 1 are mounted.

Die 3 in the press mold 10 shown in FIGS. 4 and 5
The workpiece 4 placed above is pressed from above by a punch 5 and pressed, and then lifted by a lift 6 installed in the die 3 to a horizontal surface where the finger 1 is waiting. With respect to the workpiece 4 lifted in this way, the finger 1 moves in the direction A in the figure together with the feed bar 2, and grips the workpiece 4 from both ends (clamping). The finger 1 that gripped the workpiece 4 then moves in the direction B in the figure together with the feed bar 2 (advance).
The workpiece 4 is transferred onto the die 3 which is the next press mold. In this state, the finger 1 is moved together with the feed bar 2 in the direction C in the figure (unclamped), and the workpiece 4 is dropped onto the die 3. This die 3
The workpiece 4 placed above is pressed by the punch 5 in the same manner as described above to undergo further different pressing operations. On the other hand, the finger 1 moves (returns) in the direction D in the figure together with the feed bar 2 and returns to the initial state.

In this way, as the many fingers 1 provided on the feed bar 2 repeat the above-mentioned operations, the workpiece 4 is sequentially moved onto the die 3 having different machined surface shapes, and finally a pressed part is produced. is completed. A press machine that does this is called a transfer press.

(The problem that the invention attempts to solve) However, in such a transfer press,
It was difficult to take out the workpieces that were sequentially processed and divided in the final process.

For example, in order to increase the productivity of the transfer press, by molding two pieces of the same shape or with different orientations in each process, and finally dividing the pieces into two, it is possible to increase the productivity in one cycle of the transfer press. When the production volume is to be doubled, it is difficult to grasp the divided ends of the two workpieces with fingers when simultaneously taking out the two workpieces.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a workpiece retrieval device for a transfer press that can easily take out even divided workpieces.

(Means for Solving the Problems) In order to achieve the above object, the present invention has a pair of parallel feed bars that move toward and away from each other and in the transport direction of the workpiece, which are machined using a press die. , fingers are provided to support both ends of the workpiece divided into two parts between the feed bars, and fingers are provided at a predetermined inclination angle with respect to the feed bar from an end rotatably attached to the feed bar. In a workpiece retrieval device for a transfer press, the interlocking arm is provided with a jaw for gripping the divided workpieces at the tip of the interlocking arm. A jyo is installed to grip both proximal ends of the workpiece at the same time, a guide bar is provided between the feed bars and extends parallel to the feed bar, and the jyo is installed so that it can freely reciprocate on the guide bar. It is characterized by

(Function) According to such a workpiece retrieval device, even when a divided workpiece is taken out, both ends of the divided workpiece are gripped by the fingers, and the proximal end is gripped by the jogger in a timely manner. Even two divided works can be gripped and taken out at the same time by the fingers and the jaw.

(Embodiments) Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a partial plan view showing a workpiece take-out device in a transfer press according to an embodiment of the present invention, FIG. This is a sectional view taken along the same direction, and members common to those shown in FIGS. 4 and 5 are given the same reference numerals.

FIG. 1 shows an embodiment in which works 4 divided into two rows are simultaneously taken out using the workpiece take-out mechanism according to the present invention, and FIG. 1A is in a clamped state, and FIG. 1B is in a clamped state. Indicates the return end status.

The workpiece take-out device in this transfer press consists of a pair of feed bars 2 parallel to each other,
2, and this feed bar is moved toward and away from each other by a drive means (not shown) (directions A and C in the figure), and in the direction of transport of the workpiece (directions B and D in the figure).
It is designed to move in both directions. Between the feed bars 2, a plurality of press mold dies 3 having sequentially different machined surface shapes are installed in the longitudinal direction of the feed bar 2.

A plurality of fingers 1, 1 are formed in the feed bars 2, 2 in the length direction of the feed bars 2, 2 as supporting parts for supporting the workpiece 4 to be pressed from the ends thereof. The fingers 1, 1 are formed in a number corresponding to the press molds installed at a predetermined distance between the feed bars 2, 2.

Feed bars 2, 2 are placed behind the fingers 1, 1 that grip both ends of the workpieces 4, 4, which are the final processed products that have been sequentially processed by a plurality of press dies and divided in the final process. , brackets 11, 11 are each fixed with bolts or the like. Each bracket 11 has a pin 12.
One end of an interlocking arm 13, which is rotatable by a screw, is attached to each. A pair of interlocking arms 13 are provided, and both interlocking arms 13 are
It extends at a predetermined angle of inclination with respect to the feed bars 2, 2, and its tip is rotatably mounted together with the jaw 14 by a pin 15. The jaw 14 is located approximately in the center between the feed bars 2, and is configured to operate in synchronization with the interlocking arm 13 as the feed bars 2 move.

In this embodiment, the jog 14 is located approximately in the center between each of the feed bars 2 and parallel to the feed bars 2.
A guide bar 16 is provided to guide the user.
The guide bar 16 serves to guide the movement of the jog 14 and to support the load of the jog 14.

Details of the jaw 14 are shown in FIGS. 2 and 3. As shown in FIGS. 2 and 3, the jaw 14 has a pressing member 20 and a receiving portion 21 that press and hold the end of the workpiece 4 from both sides. The receiving portion 21 is made of elastic synthetic resin or the like. In this embodiment, two pressing members 20 are attached to a rotating lever 22, and the pressing members 20 are adapted to abut on the two rows of workpieces, respectively. The rotating lever 22 is connected to the pin 2 with respect to the Jyo main body 23.
It is rotatably attached using 4 as a fulcrum. This rotating lever 22 is connected to an air cylinder 25 etc.
The rotation is controlled by the air cylinder 25 and the like. This rotation control is performed by the gripper 1
The pressing member 20 and the receiving portion 21 grip and release the workpiece 4 in response to the clamping and unclamping operations.

In addition, various rollers 2 are provided on the Jyo main body 23.
6, 27, 28, 29 are attached so that they can move smoothly on the guide bar 16, and after the workpiece 4 is divided, both the workpieces 4 are placed on the lifter etc. installed on the die 3. While the workpieces 4 are held in a predetermined position, the jyo main body 23 moves forward and grips the proximal ends of both works 4.

Next, the operation of such a workpiece retrieval device will be explained.

In FIG. 1, each feed bar 2 first moves in the direction of arrow A. In this case, when the feed bar 2 moves in the direction of the arrow A, the fingers 1 and 1 also move in the direction of the arrow A.
direction, and at the same time both interlocking arms 13,
The proximal ends of 13 also come close to each other. Therefore, the jaw 14, which is linked to the distal end side of the interlocking arms 13, 13, is pushed out on the guide bar 16 in parallel to the feed bar in the direction of arrow D. Here, the fingers 1, 1 grip both ends of the works 4, 4, and the jaw 14 grips the adjacent ends of both the works 4, 4 at the same time. In other words, since the position of this Jyo 14 that protrudes toward the press side (work side) by the interlocking arms 13, 13 further protrudes, the single feed bar 2 allows the fingers 1, 1 to grip both ends of the workpiece. At the same time, it becomes possible to grip both proximal ends of the workpiece by the Jyo 14, and the two
The entire workpiece can be gripped reliably. Then move feed bar 2 in the direction of arrow B (Advance)
Then, the two divided works 4, 4 can be simultaneously gripped and taken out of the mold. Next, when the feed bar 2 is moved in the direction of arrow C, the finger 1 is also moved in the direction of arrow C, and the gear 14 moves on the guide bar 16 parallel to the feed bar in the direction of arrow B ( The moving distance is not as large as arrow B). At this time, the finger 1 and the jaw 14 simultaneously release their grip on the workpiece 4 (unclamp). In other words, in this case as well, one movement of the feed bar 2 in the C direction simultaneously activates the finger 1 that grips the side end of the workpiece and the jaw 14s that grips both proximal ends of the workpiece. , it becomes possible to release the grip on the workpiece. When this feed bar 2 is moved in the direction of arrow D, the jaw 14 returns to its initial state and waits to take out the workpiece 4 placed on the die 3 in the previous process after dividing it.

By repeating such an operation, when the workpiece 4 is press-formed and divided into two parts, the two workpieces 4, 4 can be taken out at the same time without falling into the mold.

In addition, since the guide bar 13 extending parallel to the feed bars 1 and 1 guides the jog 14, the load of each of the two divided works 4 is transferred between the feed bar and the guide bar 16.
The workpiece can be supported at both ends, improving the weight balance, and also suppressing the vibration of the workpiece during transport, improving the stability of the workpiece during transport.

[Effects of the invention] As described above, according to the invention, it is possible to simultaneously take out and remove two divided workpieces in a timely manner by simply operating a pair of feed bars, thereby achieving highly productive transfer press processing. realizable. In addition, since the feed bar and guide bar support the load of each workpiece divided into two, the weight balance is improved.
It is also possible to suppress the vibration of the workpiece during transportation, and the stability of the workpiece during transportation is improved. For example, even if the workpiece is a plate-shaped workpiece with no rigidity, a workpiece that is relatively easily deformed, or a workpiece that is relatively heavy, it is possible to reliably grip and transport the workpiece.
