Abstract

PROBLEM TO BE SOLVED: To solve problems in cutting plastic deformed thin-walled extrusion molding that burrs are produced on a cut section after passing a blade by a various kinds of methods, the cut section is not excellent in appearance, and labors are essential therefor. SOLUTION: A work is fixed to a truck base (4) by two pairs of upper and lower fixing devices (3). When the work is cut by setting a special cutter (1) to a cutter feeder (2) and operating the feeder (2), no burrs are produced in the cut section, and an excellent cut surface is obtained. A blade tip of the special cutter (1) is finished in an arc shape (including a semi-circular shape and a shape similar to a semi-circular).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a special cutter having a cutting edge shape adapted to an object to be cut so as to cut various thin plastic molded extruded products.
It is intended to obtain a burr-free cut surface.

[0002]

2. Description of the Related Art As a conventional cutting machine which does not produce cutting powder, there is a method of cutting with a disk cutter, a cutting knife-shaped knife or the like.

[0003]

In the conventional cutting machine, since the cut surface has burrs, some products require finishing of the cut surface. The present invention has been devised to solve the above-mentioned drawbacks, and has no burrs on the cut surface and does not require finishing.

[0004]

According to the basic structure of the present invention, two pairs of upper and lower fixing devices (3) are arranged on a cutter track (4) to fix an object to be cut and finish the cutting edge into an arc. This is a structure in which the special cutter (1) is cut by being operated by a cutter feeding device (2). The present invention is a plastic extruded thin-walled extruded product cutting machine having the above configuration.

[0005]

Embodiments of the present invention will be described below. (A) When the length detector detects the length of the object, the object is fixed to the track base (4) by two pairs of upper and lower fixing devices (3). Usually, the object to be cut is moving at a constant speed, so that the track base (4) moves together with the object to be cut. (B) A special cutter (1) is attached to the cutter feeder (2).
Is set and the cutter feed device (2) is operated to cut the object to be cut. When the cutting is completed, the fixing device (3) opens the object to be cut and returns to the original position. (C) Use a special cutter (1) whose edge is finished in an arc. (D) If the special cutter (1) is finished in a semicircle or a shape similar to a semicircle, it can be cut back and forth.

[0006]

As described above, a good cut surface can be obtained without burrs on the cut surface of the object to be cut. Therefore, there is almost no need for finishing, and it can be used as it is.
