Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a method for manufacturing squid fishing A1, specifically a method for manufacturing a tc squid fishing hook combined with a rod-shaped artificial bait (prior art). There are various types of fishing buttons for attaching an umbrella-shaped diagonal to a synthetic resin bait, but there are two ways to fix the diagonal to the bait: (1) thread wrapping, and (2) insert molding.

(Problem to be Solved by the Invention) In the former thread winding means in the above-mentioned prior art, the needle rod constituting the oblique body for the thread winding operation is oriented so that the tip of the needle is oriented perpendicularly to the axis of the lure. - The needle is bent into a shape, and after winding, the needle tip is bent at a predetermined angle with respect to the axis. For this reason, the method using thread winding has poor productivity, and moreover, the needle rods become misaligned during thread winding, resulting in irregularities, resulting in a high incidence of defective products. Furthermore, since the nylon thread that fixes the needle rod expands and contracts depending on temperature and humidity, there is a problem that the fixing state of the side rod changes during inventory, and the needle rod comes off from the bait during use.

In addition, the latter type of inserter 1-molding involves setting a side rod in the mold for the bait, and embedding a part (base) of one rod inside the lure and storing it with a V. Since there is work involved in setting and removing the bait from the mold, the productivity is lower than in the production of only the bait, and there are also problems such as the bait can break due to stress concentration on the embedded part.

The present invention has been made in view of the above-mentioned problems of the conventional technology, and its purpose is to:
To provide a novel manufacturing method which is highly productive and can securely fix a needle rod to a core rod which is a bait object.

(Means for Solving the Problems) In order to achieve the above object, the method of manufacturing a squid fishhook according to the present invention includes folding a side rod having sharp edges on both sides into a substantially V-shape, and further folding the side rod into an L-shape or Bend it into the shape of the finished product, and fit the tip side of the side rod into a jig arranged radially, dividing the space where the core rod will be fitted, and align the base side with the axis of the space. Insert the tip of the core rod into the core wire in the space divided by the jig, and then insert the movable body holding the fastening ring or the jig holding the needle rod through the core rod and The core rod and the side rod are integrated by pressing a fastening ring on the outside of the base of the side rod, and further bending the needle tip at a predetermined angle as necessary. .

- It is desirable that the four side rods be arranged in a cross shape for the number of reflexes of one rod for the jig.

The core rod (parallel bait) to which the rod is fixed may be any metal rod 9, synthetic resin rod, bamboo rod, wooden rod, etc.

In addition, the method of fixing and covering the side rod with a tightening ring on the core rod is to fix one of the two between a jig with a nail driver set and a movable body holding the tightening ring, and move the other to cover the side rod. The core rod inserted into the base of the rod is fixed by the press fit of the tightening ring.

(Function) According to the above means, the fastening ring is press-fitted on the outside of the base of the side rod held on the outside of the core rod, or the fastening ring is held on the outside of the core rod. ′
The base of one rod is press-fitted into the annular space between the inner surface of the fastening ring and the core rod and the side rods are fixed together.

(Example) Embodiments of the present invention will be described below based on the drawings.

First, the side rod 1 and the core rod 2, which will be the constituent members of the squid fishing hook, are preformed.For the side rod 1, a stainless steel wire rod with a diameter of 08 mm is cut to a length of about 8 cm, and both sides of the rod are cut. is sharpened by pressing or grinding, etc., and is then folded in half into a roughly V-shape in the middle of the length direction, and is further folded in half at a position approximately 173rd in length from the base side. Form by bending at right angles. (See Figure 1) The needle rod 1 formed as described above is attached to four jigs 3a, 3b, 3c, and 3d arranged in the shape of a front opening.
are fitted and set from the inside to the outside so that the base side 1b of the side rod 1 is aligned with the axis.

The side rod 1 is set as described above, and the IC jigs 3a to 3d are fixed to the main body 5 using four pins (not shown), etc., and the jigs 3a to 3d are fitted with the core rod 2. space 4
Place them on a partition grid. (See Figure 2) Above jig 3
A positioning protrusion 6 that fits into the space 4 defined by the jigs 3a to 3d is formed on the main body 5 that fixes a to 3d, and the amount of insertion of the core rod 2 is determined by the collision with this protrusion 6. Then, the attachment position of the side rod 1 to the core rod 2 is determined, and the base side 1b of the needle rod 1 protrudes in the axial direction along the outer peripheral surface of the core rod 2.

A fastening ring 7 that fixes the side rod 1 to the core rod 2 is fitted and latched onto a movable body 8 that moves in the axial direction with respect to the main body 5 to which the jigs 3a to 3d are fixed. The movable body 8 has a through hole 9 through which the core frame 2 is inserted, and the fastening ring 7 is fitted and latched to the stepped portion of the through hole 9, and as the movable body 8 moves, the fastening ring 7 is also attached. It's like moving to.

Thereby, the core rod 2 is inserted into the through hole 9 of the movable body 8 in which the fastening ring 7 is set, and the tip of the core rod 2 is inserted into the space 4 divided by the jigs 3a to 3d, and the positioning protrusion 6 is hit. Match.

Thereafter, the moving body 8 is moved toward the jigs 3a to 3d, the moving body 8 is press-fitted onto the base side 1b of the needle rod 1, and the fastening ring 7 is press-fitted onto the outside of the needle rod 1. .

As a result, the needle rod 1 is tightly fixed to the core rod 2 with the fastening ring 7. (See Figures 3 to 5) After press-fitting the fastening ring 7, return the movable body 8 to its original position, remove the jig 3a-36 from the needle rod 1, and set the tip side 1a at a predetermined angle. Squid fishing it A is completed by folding it.

(See Figures 6 and 7) The method using the needle rod 1 bent into an L shape has been described above, but the sub-rod 1 is bent in advance to the shape (angle) of the finished product. By using the above-described assembly, a completed product is obtained.

In this case, when the movable body 8 is moved to press-fit the fastening ring 7 into the 21 rod 1'', the four rods 1' that have been fitted and turned by the jigs 3a to 3d are attached to the movable body 8. The needle presser 10 stops the needle from being pulled out because a force is applied in the direction of movement.
is provided on the main body 5. (See Figures 8 and 9.) Also, the above explanation is based on the jig 3a in which four rods 1 or 1' are set.
3d is fixed to the main body 5, and the movable body 8 with the fastening ring 7 fitted and latched to the main body 5 is moved. The body 8 and the core frame 2 are fixed at a predetermined position, the jigs 3a-36 are moved to the movable body 8 side, and the base side 1b of the sub-rod 1, which has been soldered by the jigs 3a-3d, is fastened to the core frame 2. Of course, it is also good to integrate the core frame 2 and the needle rod 1 by press fitting between the ring 7 and the ring 7.

(Effects of the Invention) Since the manufacturing method of Squid 1 according to the present invention is designed as described above, even if the core frame is long, the needle rod can be secured without applying any axial load to the core frame. It can be fixed to

Furthermore, since no load is applied to the core frame in the axial direction as described above, bamboo sticks or water rods can also be used as the core frame, and needle rods can be attached to the core frame.

Furthermore, since this method involves assembling needle rods and core frames, division of labor (subcontracting) production is possible2, and losses can be reduced while establishing a fixed state equivalent to insert molding.
