Description

[Detailed Description of the Invention] The present invention relates to a device for separating a plate material into two parts using a transfer press that performs two-piece press processing.

In transfer presses, a two-cavity system is sometimes adopted in terms of productivity. The two-cavity method means that two identical molds are used to perform the same molding process on two molds at once, but for reasons of strength, it is not possible to connect the molds together, so blank materials (material plates) are used. You need to keep a certain distance.

The present invention relates to an apparatus for cutting a plate and separating the cut pieces by a certain distance.

The cut plate pieces are then fed (transported) by the fingers of the feed bar to a mold for the next process (molding).

The present invention will be explained based on the drawings of one embodiment.

The upper mold 1 and lower mold 2 of the transfer press are provided with cutting blades 3 and 4 facing each other, and are used to control the material 5a that is transported before being divided into two, and the plate material 5a that is separated after being divided into two. Stoppers 6, 8 and a pilot pin 7 are provided protrudingly on a chute 9 installed alongside the cutting blade 3, lower die 2, and lower die 2, and are attached to the lower surface of the divided plate piece 5a on the side to be moved and separated after being divided into two parts. In addition to providing a cushion plate 10 in contact with the
A magnet roll 11 in contact with the lower surface of the divided plate piece 5a is provided rotatably and movably up and down. The magnet roll 11 is rotatable by a motor 12 or a rack pinion (not shown) from a slide, and can be raised and lowered by an air cylinder 13 or a spring (not shown).

Further, a washer 16 and a guide nut 17 are attached to the upper mold 1 with a presser pad 14 for pressing the fed material 5 onto the cutting blade 4 before dividing into two parts, and a spring 15 for biasing the presser pad 14.
It is assembled so that it can be raised and lowered freely.

Next, the operation of the present invention will be explained.

In Figure 1, the material 5 to be divided into two is placed at the stopper 6.
After being regulated by the pilot pin 7 and conveyed onto the cutting blade 4 and the cushion plate 16,
This shows the state at the time when the presser pad 14 and the cutting blade 3, which have descended together with the upper die 1, press the material 5 onto the cutting blade 4 and the cushion plate 16. When the upper mold 1 further descends, the material 5 is divided into two by the cutting blades 3 and 4, and the divided material 5a on the right side of the figure is
The cushion plate 10 suddenly descends together with the cushion plate 10 to the position shown by the two-dot chain line, and then rises as the upper mold moves upward.
When it returns to its original position, it is moved over the chute 9 by the rotating magnet roller 11, which is raised by the air cylinder 13 at the same time, and stops when it comes into contact with the stopper 8, and the separated plate material is separated. Once completed, it is transported by the fingers (not shown) of the feed bar of the transfer press, and is fed to a mold for the next process.

According to the present invention, since a rotating magnet roller that can be raised and lowered is installed under the side of the plate to be divided into two, it is possible to easily separate the two divided plates.
