Description

Cutting blade bending machine

The present invention relates to a cutting blade bending groove processing apparatus for forming a bending groove at a predetermined position on both sides in order to bend the cutting blade for sheet processing to a predetermined design position. The present invention relates to a bending groove processing apparatus for a cutting blade, in which two polishing rolls positioned on a layer are raised and lowered at predetermined intervals, thereby processing bending grooves on the upper and lower surfaces of the cutting blade.

Conventionally, the bending system of the cutting blade proposed by the present inventor has been disclosed in the publication number 97-473. In addition, a bending groove processing apparatus is also known for processing bending grooves by feeding a cutting blade on a machining surface and rotating the polishing roll laterally for application to such a similar apparatus.

However, in the former case, while cutting the cutting blade supplied from the cutting blade conveying portion to a length suitable for sheet forming, the cutting tip is discharged along a predetermined discharge path, and the cutting blade forming the cutting portion is conveyed to the bending device. It is a bending system that provides a cutting-tip processing structure and a bending device of the cutting blade while being bent in a predetermined direction by the bending means that rotates at the same time as the straight line. It is a bending device that performs bending processing while moving, so the circular motion of the bending force is considerable, resulting in high incidence of machining error and inaccurate bending state.

Thus, the latter bending device is an improved bending device for more precise bending of the bending portion of the cutting blade supplied in the vertical state. The bending device is a device for forming a groove in the bending portion of the cutting blade. It is equipped with a bending groove forming structure for supplying a cutting blade having a bending groove to a bending system in a device that supplies a blade as it is. This device installs a polishing roll (referring to a kind of rotary saw that forms a blade along the edge of the rotating plate) that rotates perpendicularly to the center of the machining surface, and supplies the cutting blade to the rotational direction of the polishing roll in a rotational direction. Inconvenience in the process of inverting the upper and lower sides of the cutting blades in order to process the bending grooves that are irregularly formed at specific positions on both sides because the formation of the bending grooves is easy to bend the specific position of the required surface of the two sides of the cutting blade. Due to this, there was a disadvantage that the processing error is high and the state of the bent portion is not accurate.

The bending grooves formed in the cutting blades during the cutting process of the cutting blades increase the bending efficiency when supplied to the former bending system, which is proposed by the present inventors. It is necessary in terms of process and manufacturing efficiency. The latter bending groove processing device is difficult to be related to the mechanical design by supplying the cutting blade horizontally, and it is difficult to design the device. There is a problem that the groove cutting speed is low and there is no precision control means for processing to the required length and the defect rate is high.

The present invention improves the structural disadvantages of the bending groove processing apparatus such as the latter while increasing the bending efficiency of the cutting blade bending device as the conventional electronics as described above, while the upper and lower surfaces are freely selected and processed simultaneously with the support of the cutting blade. It is an object of the present invention to provide a bending groove processing apparatus that can be applied as an associating device to a bending system.
