Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cutting device for cutting electric wire cables into regular lengths.

[Conventional technology and its problems]

In the work of rewinding the wire and cable, the 4th
As shown in the figure, the electric wire cable 2 is passed from the supply drum 1 to the winding drum 4 via the measuring device 3.
When the winding length of the winding drum 4 reaches a predetermined length using the measuring device 3, the length indicating tape affixed to the surface of the electric wire cable 2 in the previous process appears. The winding machine 4' is stopped, the length indication on the measuring device 3 and the position of the length indication tape are confirmed, and the hydraulic cutter is cut at the position of the length indication tape.

In this cutting work, conventionally, there is no means to hold both ends of the cut part of the electric wire cable 2, so
A worker holds the electric wire cable 2 with both hands with the strip length display tape in the center, and another worker cuts the strip length display tape with a hydraulic cutter. For this reason, two or more workers are required, and
The electric wire cable 2 had to be held with both hands each time the measuring tape was cut, resulting in a problem of poor work efficiency.

[Purpose of invention]

SUMMARY OF THE INVENTION In view of the above points, an object of the present invention is to provide a scale cutting device that can efficiently cut electric wires and cables.

[Means to achieve the purpose]

In order to achieve the above purpose, in this invention,
A frame having a cutter for cutting the electric wire cable is provided so as to be movable in the vertical direction with respect to the running line of the electric wire cable fed out from the supply drum. Lateral V-shaped springs that open vertically are provided, and the frame is provided with driving means for the cutter.

[Effect]

The measure cutting device according to the present invention configured as described above stops the running of the electric wire cable when it is fed out to the fixed length position, moves the frame toward the electric wire cable, and inserts the frame into both leaf springs. Pinch and hold the electric wire cable. At this time,
The leaf spring reliably holds the electric wire cable by its bending in an appropriate manner depending on the diameter of the electric wire cable. In this holding state, the cutter is driven to cut the electric wire cable between the holding positions.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 to 3, the measuring meter cutting device A according to the present invention includes a hydraulic cutter 5 for cutting the electric wire cable 2, a holding part 11a for holding the electric wire cable 2 during cutting, and a hydraulic cutter 5 for cutting the electric wire cable 2. A bracket 14 that holds the cutter 5 and the clamping portion 11a, and a guide rail 1 that supports the bracket 14 via wheels 15 so as to be movable in parallel to the running direction of the electric wire cable 2.
6 and a hydraulic unit 17 that supplies oil to the hydraulic cutter 5 are mounted on a frame F, and this frame F serves as a trolley 25 with wheels 26 and supports the running of the electric wire cable 2 via a guide rail 27. It is possible to move in the direction perpendicular to the line (vertical direction).

The hydraulic cutter 5 is supported by a hanging bolt 9 on an arm 10 that projects horizontally from the bracket 14 and is loosely fitted into a guide ring 13, and receives hydraulic pressure from an oil tank 19 of a hydraulic unit 17 by a hydraulic pump 18. It consists of a hydraulic cylinder 6 that operates the cutter blade 7 with oil sent through a hose 20. The guide ring 13 is supported by an arm 10' projecting from the bracket 14.

In the clamping part 11a, a V-shaped plate spring 11a' which clamps the electric wire cable 2 is loosely fitted into a slidable guide pipe 11b so that the clamping position can be changed depending on the outer diameter of the electric wire cable 2, and is held at an appropriate position. It is provided with a fixing bolt 11c that can be fixed. However, the bending of the leaf spring 11a' can accommodate a certain degree of change in the diameter of the electric wire cable 2. Guide pipe 11b
is supported by an L-shaped bracket 10a provided on the side surface of the guide ring 13.

The meter cutting device A configured as described above cuts the electric wire cable 2 in the previous process according to the length display of the meter 3.
Length indication tape 2 affixed to the top to indicate the standard length position
Make sure that a is correct, and then turn V in advance so that the wire cable 2 is at the cutting position of the cutter blade 7.
The shaped holding part 11a is slid in the guide pipe 11b at an appropriate position according to the outer diameter of the electric wire cable 2, and fixed with a fixing bolt 11c, and the fixed length display tape 2a of the electric wire cable 2 is fixed. The bracket 14 and the carriage 25 are moved vertically and horizontally along the guide rails 16, 27 by the handle 8 so that the position is at the cutting position of the cutter blade 7, and the electric wire cable 2 is held by the holding part 11a at the position 2a.

Next, two hydraulic cutter start push button switches 2 provided on the hydraulic cutter 5 and the trolley 25 are activated.
2 and 23 with both hands to cut the electric wire cable 2. The hydraulic cutter 5 has a circuit that does not operate unless two hydraulic cutter activation pushbutton switches 22 and 23 are pressed simultaneously. Both ends of the cut electric wire cable 2 are held between the holding parts 11a, and the end on the winding machine 4' side is fixed to the winding drum 4 as the terminal end of the winding drum 4, and the end on the side of the supply drum 1 is fixed to the winding drum 4 as the terminal end of the winding drum 4. In this case, the winding drum 4 is replaced with an empty drum, fixed to the winding drum 4 as the winding start terminal of the winding drum 4, and the meter cutting device A is returned to its original position. repeat.

[Effect of idea]

The present invention is configured as described above, and since the entire device can be removed from the running line by moving the frame while the electric wire cable is running, there is no problem in running the electric wire cable. On the other hand, if the frame is moved toward the electric wire cable, the electric wire cable is clamped by the leaf spring, and the electric wire cable can be easily cut. At this time, changes in the diameter of the electric wire cable can be accommodated to some extent by the degree of deflection of the leaf spring.
