Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to the improvement of a filament fuser used for terminal processing of steel cords, stranded wires, etc. used for reinforcing tires and belts. .

[Conventional technology and its problems]

Conventionally, steel cords used for reinforcing automobile tires tend to fall apart if the ends are left cut, and when the steel cords are passed through a calender during the tire manufacturing process, the tips get caught. There were problems in that workability was extremely poor, and it was extremely dangerous as the loose strands could poke one's fingers and cause injury.

For this reason, after cutting the steel cord, the tip was welded to make it spherical. However, since this welding work is carried out using a welding machine 20 shown in Fig. 4, which is normally used for welding wires, the reel on which the steel cord is wound must be brought to the welding machine. However, there was a problem that the work was complicated.

Another idea was to carry the welder 20 to a place where the reels are stored and process the ends of each of the stacked reels one by one. The flames can spread to the steel cords stacked on top of each other, causing the strands of the welded steel cords to break, reducing the tensile strength, and causing dirt and foreign matter to adhere to the steel cords, reducing the quality of the steel cords and causing damage to the rubber. There was a problem that it also inhibited the adhesion of the material.

[Means for solving problems]

The present invention has been made in order to eliminate the above-mentioned problems, and consists of two electrodes arranged and fixed at a required interval on the main body of the fuser, and two filament bodies facing the two electrodes. A holder having a presser piece is disposed so as to be movable back and forth, a movable lever for moving the holder is disposed on the fuser body so as to be swingable by a shaft, a spring is disposed between the holder and the movable lever, and By arranging a cover that moves in the same direction as the holder moves as needed and covers the fixed electrode and the moving striatum presser piece, it is easy to operate, reliably fuses, and produces high-quality wires. The object of the present invention is to provide a filament fuser capable of producing a filament.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

[Example 1] As shown in Fig. 1 and Fig. 2 A and B, 1 is a cylindrical fuser body with a sealed front surface, and a filament 2 is inserted through a part of it from the top surface to the side surface. An opening 3 is provided.

Reference numeral 4 designates electrodes, and two electrodes 4a and 4b are arranged and fixed at a required interval on a pedestal 5 fixed to the inner bottom of the fuser body 1.

Reference numeral 6 denotes a filament body holding piece that presses the filament body 2 against the electrode 4, and the two press pieces 6a, 6b are removably attached to the holder 7 with a required spacing in opposition to the electrodes 4a, 4b. It is being

The holder 7 is disposed on the pedestal 5 so as to be movable back and forth with respect to the electrode 4.

Reference numeral 8 denotes a movable lever formed in an inverted L-shape,
The shaft 9 is arranged on the blower body 1 so as to be freely swingable.
The horizontal end 11 is provided facing the holder 7, and the other end 12 is disposed protruding from an opening 10 provided in the lower part of the blower body 1, forming a finger hook.

A spring 13 is disposed between the holder 7 and the horizontal end 11 of the lever 8, forming a filament fuser 14.

Note that it is more effective to dispose a spring 15 between the lever 8 and the fuser body 1 to constantly return the lever 8 to its original position.

Further, 16 is a contact member for transmitting the action of the lever 8 to the spring 13.

Furthermore, although the fuser body 1 is shaped like a short gun with a grip part 17 at the rear, it may also be of a cylindrical type without the grip part 17. In this case, the moving lever 8 is rod-shaped, and from the rear of the fuser body. It is also possible to act.

[Example 2] Striatal fuser 14 configured similarly to Example 1
As shown in FIG. 3, a slit is formed in the top or side of the fuser body so that the channel-shaped cover 18 covering the opening 3 provided on the top and side of the fuser body 1 moves in conjunction with the movement of the holder 7. The cover 18 and the holder 7 or the contact body 16 are connected with a pin or the like through the slit to be supported and fixed.

Further, a notch 19 is provided on the front side surface of the cover 18, so that the filament 2 can be inserted therethrough when the opening 3 is closed.

By providing the cover 18 as described above, spatters do not fly out when the filament is cut by melting, and welding to the surrounding filament bodies can be prevented.

In each of the above embodiments, the electrode 4 and the holding piece 6 are arranged on the pedestal 5, but it is also possible to arrange them directly on the main body 1 without providing the pedestal 5.
Further, the electrode 4 and the pedestal 5 or the main body 1 may be connected to each other through an indestructible material, or the pedestal 5 and the main body 1 may be
It is also possible to construct it from a green body.

Further, although a material having a green-proofing property is used for the holding piece 6, it is also possible to improve conductivity by using electrodes, eliminate mistakes in fusing, and improve efficiency.

The electrode 4 or the electrode serving as the holding piece 6 is energized from the power source via a transformer, and the switch is activated simultaneously with the pressing of the filament 2 by the action of the lever 8, but it may also be provided separately. can.

Further, the cover 18 or the fuser main body can be opened and closed from the top and both sides in the middle using a hinge or the like in order to clean the electrode section.

[Action]

When fusing a filament 2 such as a steel cord or stranded wire using the filament fuser 14, the fusing portion of the filament 2 is placed on the pedestal 5 between the electrode 4 and the holding piece 6. By pulling the lever 8, the filament 2 is held between the electrode 4 and the holding piece 6, and by turning on the switch, electricity is applied.

A current flows between the electrodes 4a and 4b through the filament 2, and due to the electrical resistance of the filament 2, the electrodes 4a,
4b generates heat and is fused, and the fused striatum 2
A spherical weld is formed at the end.

[Effect of idea]

Since the striatal fuser of the present invention has the above configuration,
Since the structure is very simple, it is extremely easy to transport and handle.

Furthermore, by arranging the cover, spatter during fusing does not fly off, and other filaments do not break, and foreign matter does not adhere, which is an excellent practical effect of preventing the occurrence of defective products. It is something that you have.
