Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of Invention] (Field of Industrial Application) The present invention relates to a panel take-out device for taking out a panel having flange portions at both ends from a press die.

(Prior Art) A metal panel 1 shown in FIG. 5 has a general flange portion 2 bent at an angle of approximately 90 ° on one end side and bent at an angle of 90 ° or more at the other end side. The blind spot flange portion 3 is provided. The panel 1 having such a shape has a problem of die cutting after pressing.

Conventionally, as illustrated in FIG. 6, the general flange portion 2 is formed by the first movable die 5 and the blind spot flange portion 3 is formed by the second movable die 6. After pressing, the end face of the general flange portion 2 is pushed up by driving the first push-up member 7 in the direction of arrow a in the figure, and the second push-up member 8 is driven diagonally in the direction of arrow b. As a result, the end surface of the blind spot flange portion 3 is pushed up and the panel 1 is die-cut.

(Problems to be Solved by the Invention) In the case of the conventional example described above, when the panel 1 is demolded, the two independent lifting members 7 and 8 move in different directions, so that the demolding is smoothly performed. To do the lifting member 7,8
Delicate motion control is required. If the operation timing of the push-up members 7 and 8 deviates for some reason, the panel 1
A force that causes the panel to be bent is generated, and a part of the panel 1 may be plastically deformed.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a panel take-out device for a press die that can smoothly remove a panel after pressing.

[Structure of the Invention] (Means for Solving the Problems) A device of the present invention developed to achieve the above object is a mold main body having a first edge portion for receiving a general flange portion of a panel, It has a push-up member that is provided so as to be movable in a direction to push up the end face of the general flange portion with respect to the mold body, and a second edge portion having an overhanging shape that receives the blind spot flange portion of the panel. At the same time, a movable split mold provided so as to be movable in the same direction as the push-up member with respect to the mold body, and a drive mechanism for moving the push-up member and the movable split mold in the direction in an interlocking relationship with each other. is doing.

(Operation) In the panel take-out device of the present invention, the pushing mechanism and the movable split die are driven in the same die-cutting direction in synchronization with each other by operating the drive mechanism after pressing. That is, the general flange portion of the panel is pushed up by the pushing-up member, and the blind spot flange portion is pushed up with the movable split mold fitted. Since the pushing-up directions of these two members are parallel to each other, no force that deforms the panel is generated. When the general flange portion is disengaged from the first edge portion of the mold body by this pushing-up operation, the blind spot flange portion is also disengaged from the second edge portion of the movable split mold.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

As shown in FIG. 1, the panel 1 is placed on the mold body 10. The panel 1 is made of sheet metal and is used, for example, as a side panel of an automobile body. As shown in FIG. 5, the panel 1 includes a panel main body 1a having an outwardly convex shape and a gently curved shape, and the panel main body 1a.
A general flange portion 2 located at one end of the panel and bent at a right angle, and a blind spot flange portion 3 located at the other end of the panel body 1a and bent in the direction of the general flange portion 2. I have it. That is, the blind spot flange portion 3 has an overhang shape that faces the inside of a line segment along the die cutting direction.

The mold body 10 has a first edge portion 11 located at the left end in the figure. The first edge portion 11 receives the general flange portion 2 of the panel 1. A push-up member 12 is provided near the first edge portion 11. The lifting member 12 is
It is provided so as to be movable with respect to the mold body 10 in the vertical direction in the drawing, that is, in the direction in which the end surface 13 of the general flange portion 2 is pushed up. The push-up member 12 is biased in the upward direction by a biasing means 14 using, for example, a spring or a gas cushion.

As shown in FIG. 2, a first movable die 17 is provided above the push-up member 12. The first movable die 17 is driven in a direction for forming the general flange portion 2 by a die driving mechanism (not shown).

A movable split mold 20 is provided on the right end side of the mold body 10 in the drawing. The movable split mold 20 is provided so as to be movable up and down with respect to the mold body 10, that is, movable in the same direction as the push-up member 12. A second edge portion 21 having an overhang shape that receives the blind spot flange portion 3 of the panel 1 is provided on the upper end portion of the movable split mold 20.

As shown in FIG. 3, a second movable die 22 is provided diagonally above the second edge portion 21 so as to be movable back and forth. The movable die 22 is driven by a die driving mechanism (not shown) in a direction for forming the blind spot flange portion 3 into a predetermined angle.

A shaft 25 is connected to the movable split mold 20. The shaft 25 can be moved up and down along a guide 26. A drive arm 27 is connected to the lower end side of the shaft 25. The drive arm 27 can rotate about a shaft 28 and a reciprocating actuator such as a cylinder mechanism via a lever 29.
It is designed to be driven by 30. When the rod 31 of the actuator 30 is in the extension side position shown in FIG. 1, the movable split mold 20 is in the lowered position, and when the rod 31 is moved to the contracted side as shown in FIG. Twenty projecting upwards.

The lifting position of the pushing-up member 12 is regulated by the stopper 35. Stopper 35 is shaft
It is provided at the upper end of 36. The shaft 36 can move up and down along the guide 37. On the lower end side of the shaft 36,
The drive arm 38 is connected. This drive arm 38
It is rotatable about the shaft 39, and links 41, 42, 43
Via the drive arm 27 on the right side in the figure. The drive arms 27 and 38, the lever 29, the actuator 30, the links 41 to 43, and the like constitute a drive mechanism 45 for vertically moving the push-up member 12 and the movable split mold 20 in an interlocking relationship.

Next, the operation of the apparatus of the above embodiment will be described.

As shown in FIG. 1, the push-up member 12 and the movable split mold 20.
Is held at the lower limit initial position, and the panel 1 is placed on a predetermined position of the mold body 10. Then, as shown in FIGS. 2 and 3, by driving the movable molds 17 and 22 in the pressing direction, the general flange portion 2 and the blind spot flange portion 3 are bent into predetermined shapes.

After that, as shown in FIG. 4, the rod 31 of the actuator 30 is operated toward the contraction side, so that the shaft 2
Increase 5,36. By doing this, the movable split type 20
Moves up to the die cutting position, and the stopper 35 also moves up to a predetermined position. Therefore, the pushing-up member 12 biased by the biasing means 14 follows the stopper 35 and rises to the die-cutting position, thereby pushing up the end surface 13 of the general flange portion 2. In this way, the general flange portion 2 and the first edge portion 11 of the mold body 10 are disengaged.

At the time of the die cutting, the blind spot flange portion 3 rises to the die cutting position while being fitted to the second edge portion 21 of the movable split die 20, but this rising direction is parallel to the rising direction of the general flange portion 2. Therefore, no harmful force for bending the panel 1 is generated. As shown by the chain double-dashed line in the figure, when the general flange portion 2 is disengaged from the first edge portion 11, the blind spot flange portion 3 can also be disengaged from the second edge portion 21.

[Effect of the Invention] According to the present invention, the panel can be smoothly taken out from the mold without being deformed when the mold is removed.
