Description

[Detailed Description of the Invention] The present invention relates to a partial temporary bending device for temporarily assembling press-molded thin metal parts for automobiles, refrigerators, etc.

For example, the door and bonnet of a car are shown in Figure 1.
As shown in Figure 2, the outside (outer) a and the inside (inner) b are overlapped, the peripheral edge of the outside (a) is folded back, and the inner edge (b1) is pressed down to assemble and join. Before proceeding to the main bending step, the edge a1 is bent at a substantially right angle in advance, and the inner side b is overlapped with the outer side a to set the mutual positional relationship correctly,
A portion of the bent portion a1 is temporarily bent as shown in a1', and the inner and outer sides a and b are temporarily assembled, and then transported to the main bending device.

However, in the case of car doors, for example, the size of the door differs depending on the model of the car body, so the conventional partial temporary bending device for temporary assembly is also different for each shape size (height, die slope, bending position, etc.). It is configured separately. As a result, there are many models, and there are many problems such as the cost and storage space required to replace and install each model.

Therefore, the present invention uses the partial temporary bending device as a base.
The purpose of the present invention is to provide an economical partial temporary bending device by using a dual-purpose driving mechanism and configuring the partial temporary bending operation portion to be replaced in a cassette type manner.

That is, the base 1 to which the bending punch drive mechanism 2 is attached
a bending die support 3 having a joint 3a corresponding to the joint 1a formed on the base 1; It consists of a bending punch support arm 4, a bending die 6 provided on the top of the support stand 3, and a bending punch 7 provided on the top of the support arm, and
The following joint part 1a of the support stand 3 and the interlocking part of the support arm 4 with respect to the drive mechanism 2 are constructed in the same way, and the swing shaft 5 and above, together with the bending die 5 and the bending punch 7, have different dimensions depending on the size of the workpiece. It is equipped with several types of actuating parts configured in different shapes, and these actuating parts are mounted on a common base 1.
This is a partial temporary bending device for metal sheet molded products that is configured to be replaceable in a cassette type.

Note that Fig. 1 shows a fluid pressure cylinder 2 as a drive mechanism.
are installed on the base 1 so as to be arranged in the vertical direction via the support arm 4 so that the piston acts in the vertical direction,
FIG. 2 shows a configuration in which the bending punch support arm 4 is actuated in a pushing-up manner, in which the fluid pressure cylinder 2 is arranged horizontally at the bottom of the base 1 and the support arm 4 is swung. The drive mechanism 2 may be a cam mechanism, an electromagnetic mechanism, or the like in addition to the above-mentioned hydraulic or pneumatic cylinder. 9 is a support arm return spring. The positioning joint parts 1a and 3a have one of them 1a as a fork-shaped recess, into which the other protrusion 3a is inserted, engaged and positioned, and fixed with bolts 8.

FIG. 3 shows an example of the installed and used state of the device of the present invention, in which a workpiece W is placed on a pedestal plate 10 via a suitable table and positioned by a member 11. The partial temporary bending device M of the present invention is installed at several necessary locations around the workpiece W, and by simultaneously operating its drive mechanism 2, the bending punch 7 is operated to bend the outer edge a1.
Temporary bending a1' of a portion of is performed simultaneously at several locations.

If the shapes and sizes of the workpieces W are different, remove the die support stand 3 and punch support arm 4, which are integrally connected by the shaft 5 which is the operating part, from the base 1 together with the bending die 6 and bending punch 7, and separate the multiple bases. 1 part of pedestal plate 1
After being relocated to the base 1, the replacement working part is attached to the base 1.

Therefore, the base 1 and the drive mechanism 2 are left on the pedestal plate 10 for dual use.
By attaching and detaching the device in a cassette manner, equipment costs, replacement work costs, storage costs, etc. can be significantly reduced.
