Abstract

(57) [Abstract] [Purpose] Prevents lateral displacement of the cutting blade on the movable side to perform accurate cutting. [Structure] In a cutting blade of a push-cut type wire rod, which comprises a combination of a movable side cutting blade 2 and a fixed side cutting blade 1, a lateral deviation prevention guide 3 for the movable side cutting blade 2 is attached to the fixed side cutting blade 1. Set up.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cutting blade for accurately cutting a wire rod.

[0002]

[Prior art]

 Conventionally, there have been methods such as shearing or push cutting for cutting the wire rod, but when the wire rod is metal, a push cut type cutting blade is mainly used.

Such a conventional press-cutting type cutting blade is composed of a combination of a pair of upper and lower cutting blades, one of which is a fixed-side cutting blade and the other of which is the other. The cutting blade moves as a cutting blade on the movable side, and cuts the wire rod interposed between the upper and lower cutting blades.

[0004]

[Problems to be solved by the device]

 However, such a conventional push-cutting type cutting blade does not have any means for preventing lateral deviation of the movable cutting blade, so that the lateral deviation of the movable cutting edge occurs due to the resistance of the material during cutting of the wire. There was a problem that the wire could not be cut accurately. For this reason, the appearance of the cut surface also varies greatly, which is not desirable for the product.

The present invention has been made in view of such circumstances, and an object thereof is to prevent a lateral displacement of a cutting blade on a movable side and to perform a highly accurate cutting. It is to provide a cutting blade for material.

[0006]

[Means for Solving the Problems]

 In order to achieve such an object, the present invention provides a cutting blade of a push-cut type wire rod, which comprises a combination of a cutting blade on the movable side and a cutting blade on the fixed side. It is characterized in that a lateral deviation prevention guide is provided.

[0007]

[Action]

 When the movable-side cutting blade moves toward the fixed-side cutting blade, the movable-side cutting blade is fitted into the lateral deviation prevention guide provided on the fixed-side cutting blade to ensure the accuracy of the wire rod. Make a cut.

[0008]

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an exploded perspective view of a wire cutting blade according to the present invention. This cutting blade is a push-cut type cutting blade that serves as a fixed-side cutting blade (lower side in the drawing) and a movable-side cutting blade. It is configured by a combination with a cutting blade 2 (upper side in the drawing) that serves as a cutting blade.

Reference numeral 3 denotes a lateral deviation prevention guide provided on the stationary cutting blade 1. The lateral deviation prevention guide 3 is provided with a remaining portion of the cutting blade 1 and a clearance 2a for inserting the cutting blade 2 separated. There is.

On the center line of the lower surface of the cutting blade 2, an upper blade 5 for cutting the wire rod is provided in a protruding manner, and on the center line of the clearance 2 a of the cutting blade 1, the upper blade of the movable side cutting blade 2 is provided. A lower blade 4 is provided so as to come into contact with the lower blade 5.

Further, in a direction orthogonal to a direction in which the lower blade 4 of the cutting blade 1 and the upper blade 5 of the cutting blade 2 are in contact with each other, the remaining portion of the cutting blade 1 has a wire rod (not shown) to be cut. The guide hole 6 is formed so as to penetrate therethrough, and the escape hole 7 for the cut wire rod is formed at the portion of the lateral deviation prevention guide 3 so as to penetrate therethrough.

Next, the operation of this embodiment will be described. First, the wire to be cut is fed through the wire guide hole 6 to a predetermined size. When the movable cutting blade 2 is inserted into the clearance 2a provided in the cutting blade 1, the upper blade 5 of the cutting blade 2 pushes the wire between the lower blade 4 and the lower blade 4. It At this time, the cutting blade 2 is laterally displaced due to the material resistance of the wire. However, in this embodiment, since the cutting blade 1 has the lateral deviation prevention guide 3 for the cutting blade 2, the lateral deviation of the upper blade 5 in the cutting blade 2 is eliminated and the wire can be cut accurately.

[0013]

[Effect of device]

 As described above, according to the present invention, the lateral displacement of the cutting blade on the movable side is eliminated as compared with the conventional push-cutting method using nippers or pliers, so that the push-cutting of the wire can be performed with high accuracy. In addition, the improvement of the cutting accuracy allows the wire to have a cut surface with no variation in appearance.
