Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a press-linked shearing device, and in particular, it is configured so that the clearance between the upper and lower cutting blades can be adjusted from the discharge side of the workpiece.
The present invention relates to a press-linked shearing device that can achieve remarkable efficiency in shearing operations.

Conventionally, the structure of the clearance adjustment means between the blades of this type of shearing machine has often caused inconvenience in actual use, and especially in the case of a press-linked type, the film remains as a residual material after press processing. In many cases, the clearance adjustment part was placed on the insertion side of the plate material, so it was necessary to temporarily stop operations when adjusting the clearance, or the adjustment was extremely difficult, or it was virtually impossible to adjust it. The disadvantage was that it was close.

SUMMARY OF THE INVENTION The present invention aims to solve these drawbacks and to provide an improved press-linked shearing device that can further improve work efficiency.

Its feature is that the clearance adjustment section is arranged on the cut material discharge side of the shearing device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a press-linked shearing device according to the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a front view of the shearing device with some press linking parts omitted, and FIG. 2 is a right side view thereof.

In the figure, reference numeral 9 denotes a fixed base on which the shearing device 30 is arranged and fixed adjacent to a press device for connecting and punching film-like plate materials (not shown). Left and right side frames 14 and 16 are provided with mounting portions 12 and 13 to be fixed to a foundation (not shown) together with the fixed base 9 (left and right sides in the figure).

Further, a connecting portion 8 with a press device is provided on the back side of the fixed base 9, and a discharge portion 7 for discharging cut material is provided on the front side.

Thus, the intermediate base 6 is mounted on the upper side of the fixed base 9 by being positioned in the discharge part 7, and the mounting base 5 of the fixed blade 2 is attached to the step part 6a of the intermediate base 6 at the press connecting part 8 shown in the second figure. The intermediate base 6 is slidably mounted with a sliding clearance gap 5g between the stepped portions 6a of the intermediate base 6.

Further, the lower part of the mounting base 5 is screwed into the press connection part 8 direction from the discharge part 7 side of the fixed base 9, and the tip part 4a is inserted into the screw part 6b of the intermediate base 6 (see FIG. 2). A plurality of threaded clearance adjustment bolts 4 are attached to the mounting base 5.
They are arranged at required intervals along the length.

That is, the mounting base 5 of the fixed blade 2 is
By rotating and adjusting a plurality of clearance adjustment bolts 4 from the ejection part 7 side of the fixed base 9, it is possible to slide through the slide allowable gap 5g between the press connecting part 8 and the step part 6a of the intermediate base 6. It is.

Note that a nut 4n is screwed onto each adjustment bolt 4 after adjustment in order to firmly fix the adjustment bolt 4 to prevent unnecessary rotation.

Furthermore, the fixed blade 2 is attached to the attachment base 5 with a plurality of attachment bolts 3.

In addition, a rotary shaft 19 is rotatably installed between the upper ends of the left and right frames 14, 16 via bearings 17, 18, and a press device is installed in the center of the rotary shaft 19. The shearing actuating arm 15 is connected to the shearing actuating arm 15 through a linking arm 20, with the connecting portion 21 being solidly connected.

Further, the movable base 10 of the upper blade 1 is connected to the left and right side frames 1 through the connecting parts 22 and 23 to the rotation shaft 19.
The upper blade 1 is held movable up and down while being guided by guide parts 24 and 25 attached to the movable base 10, and is attached to the movable base 10 by a plurality of mounting bolts 26 so as to face the fixed blade 2. .

Now, the press-linked shearing device 3 of the present invention
0 has the above-mentioned configuration, and when this is used, the connecting part 8 is connected to a required press device so that the film-like plate material after pressing can be inserted into the cutting part of the shearing device 30. The upper blade 1 can be set for operation in connection with the operation of the press device through a connecting arm 20 with the press device.

When the press device is operated under this arrangement, the operating arm 15 of the shearing device 30 is interlocked via the connecting arm 20, and the upper blade 1
The upper blade 1 and the fixed blade 2 are inserted between the upper blade 1 and the fixed blade 2.
It can be cut by.

In addition, under this arrangement, if the material or thickness of the film-like plate material used as the press material on the press device side is changed, by rotating each adjustment bolt 4 from the discharge part 7 side,
Mounting base 5 of fixed blade 2 relative to intermediate base 6
The clearance between the upper blade 1 and the fixed blade 2 can be adjusted by sliding the blade.

That is, the appropriate clearance between the upper blade 1 and the fixed blade 2 is selected depending on the material and thickness of the material to be cut, but in the press-linked shearing device of the present invention, each clearance adjustment bolt 4
This can be achieved by adjusting both the slides of the mounting base 5 of the fixed blade 2, and since the adjustment work can be performed from the cut material discharge section 7 side of the fixed base 9, it can be done even during operation or when the cutting machine Even when changing frequently, the clearance can be easily adjusted quickly and efficiently.

As can be seen from the above explanation, the press-linked shearing device according to the present invention has the advantage of having an excellent clearance adjustment means, and can successfully adjust the clearance, which was nearly impossible with conventional shearing machines of this type. In addition to being able to solve this problem, it also has the effect of further increasing work efficiency in shearing operations.
