Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous mold material cutting method for connecting and continuously cutting mold materials, an apparatus therefor, and a mold material connecting device.

[0002]

2. Description of the Related Art Conventionally, for example, a pipe as a mold material has not been mechanically connected for continuous automatic cutting, but a single pipe is supplied to a saw machine which is a cutting machine by using a loading device. It is common to have

[0003]

By the way, in the case of supplying materials to, for example, a saw machine as a cutting machine using the above-mentioned conventional loading device, the cutting size is relatively large due to a large variety of small quantity production or a small variety of mass production. When performing continuous automatic cutting for a long time, a plurality of materials are required, which is advantageous. In addition, when the cutting size is relatively small and the material size is relatively large in the small-quantity large-scale production, the operating time of the loading device is significantly shorter than the operating time of the saw. In this case, since the loading device is generally the same price as the saw machine or more, it is more advantageous to buy another saw machine than to buy the loading device. The device had a problem that it was disadvantageous.

Therefore, in such a case, it seems that a general loading device is unnecessary, but for example, in the case of performing unmanned cutting from the middle of the cutting, the material cannot be supplied, so that it takes a short time. There is a problem that the material runs out.

The object of the present invention is to improve the cutting efficiency by connecting the mold members with the mold member connecting device with the mold member connecting device and continuously and automatically avoiding the connecting portion, and at the same time reduce the cost by simplifying the equipment. It is an object of the present invention to provide a die material continuous cutting method, a device therefor, and a die material connecting device.

[0006]

In order to achieve the above object, the method for continuously cutting a mold material according to the present invention according to claim 1 is a cutting machine of a cutting machine when the mold materials connected by the mold material connecting device are continuously connected to a desired size. From the time when a sensor provided at a position apart from the cutting position in the material feeding direction by a predetermined distance detects the connecting portion connected by the mold material connecting device, a plurality of mold materials are cut to the desired size within a range in which the mold material can be cut. Then, next, only the material feeding is performed without cutting the connecting portion connected by the mold material connecting device, and after the connecting portion is avoided, the continuous cutting is performed again to a desired size.

According to a second aspect of the present invention, there is provided a continuous cutting apparatus for mold material, which comprises a main body vice device for clamping and fixing the mold material on the material feeding side of the cutting machine, and a movable mold material adjacent to the main body vice device. From the cutting position of the cutting machine that detects the connection part connected by this material connection device and the material connection device that connects the plurality of material materials that are supplied by this material connection vise device A sensor installed at a position distant from the material feeding side by a predetermined distance and a desired position for performing continuous cutting to a desired dimension from the time when this sensor detects the connecting portion of the mold material connected by the mold material connecting device. It is characterized by comprising a cycle counter having dimensions set therein and a cycle counter having a length of a connecting portion connected by the mold material connecting device set therein.

Further, the mold material connecting device of the present invention according to claim 3 is provided with a plurality of pressing plates inserted into the mold material,
A right and left threaded screw hole is provided in each thickness direction of the pressing plate to form a right screw and a left screw to be screwed into the screw hole, and a fastening member having a length that does not protrude from the outer diameter of the mold material. Is provided.

[0009]

With the method and apparatus for continuously cutting a mold material according to claims 1 and 2 described above, a plurality of mold materials are integrally connected by a mold material connecting device, and the connected mold materials are continuously connected to a desired size. At the time of cutting, a sensor provided at a position apart from the cutting position of the cutting machine to the material feeding side by a predetermined distance detects the connecting portion connected by the mold material connecting device.

Then, continuous cutting is performed by the set value of the cycle counter calculated how many times it can be cut to a desired dimension, and then the cycle counter is set to set the length of the connecting portion of the connected mold materials without cutting. After only feeding the material and avoiding the connection part, the continuous cutting is performed again.

As a result, it is much cheaper than the conventional loading device and the continuous automatic cutting time can be extended.

Further, with the mold material connecting device according to the third aspect, since the fastening member adopted in the mold material connecting portion does not protrude from the outer diameter of the mold material, smooth material feeding can be performed without hindering the material feeding.

The material feeding vise device 11 includes a fixed vise jaw 13, a movable vise jaw 15 provided to face the fixed vise jaw 13, a hydraulic cylinder 17 for moving the movable vise jaw 15 forward and backward with respect to the fixed vise jaw 13. Although not shown in the drawings, the material feeding vise moving cylinder is actuated so as to move closer to and away from the main body vise apparatus 3.

The mold material connecting device 19 for connecting the pipe materials W is constructed by screwing a plurality of pressing plates 21A and 21B with a fastening member 23 having right and left screws.

More specifically, referring to FIGS. 2 and 3,
The pressing plates 21A, 21B inserted into the pipe W have arcuate surfaces 25A, 25B formed at both ends, and the arcuate surfaces 25A, 25B abut against and hold the inner surface of the pipe W. . Then, right and left screw holes 27R and 27L are formed in the center thickness direction of the pressing plates 21A and 21B. The right screw 29R and the left screw 29L formed on the fastening member 23 are screwed into the screw holes 27R and 27L, and a tool is mounted in the hexagonal hole 31 provided at the end of the fastening member 23 to fasten the fastening member 23.
