Semi-rigid cable bending device {A BENDING MACHINE OF SEMI RIGID CABLE}

The present invention relates to a bending device of a semi-rigid cable, in particular a bending device is moved to bend the semi-rigid cable, so that the bending device is manufactured not so large, and the structure is simple and the manufacturing cost of the semi-rigid cable bending device It is about.

Generally, coaxial cables are classified into soft flexible cables (RG C / B) and rigid semi-rigid cables (SEMI RIGID CABLE).

In the conventional semi-rigid cable bending device, the head of which the cable is fixed is operated by the servomotor to bend.

However, the conventional bending device of the semi-rigid cable has a drawback in that the bending device is large because the head moves, and the manufacturing cost is also high because the head is operated by an expensive servo motor.

Therefore, the present invention was devised to solve the above-mentioned drawbacks, and the bending part moves to bend the semi-rigid cable, so that the bending device is not largely manufactured and the pneumatically operated structure is simple and the manufacturing cost is low. The object is to provide a bending device for rigid cables.

The bending device of the present invention semi-rigid cable is a multi-stage frame (10) installed at the bottom so that the PLS and the electric components (not shown) are installed inside to have power and air pressure, and the upper part of the frame (10) A bending unit 20 installed on the bed 13 and installed to move left and right by the servo motor M and the ball screw B so as to be able to bend the cable C inserted into the head to be described later, and the frame ( 10 is installed on one side of the head 30 is configured to be rotatable while moving back and forth, and configured to grip one end of the cable (C), and is installed at the upper predetermined position of the frame 10 of the bending unit 20 The operation unit 40 is configured to manipulate the operation state, and one side of the frame 10 is connected to the operation unit 40 and PLC to remove the cable (C) from the head 30 and the bending unit 20 Includes a remote control unit 50 for operating the The.

When the chucking button 51 of the operation unit 40 and the remote control unit 50 is operated, the cable C is inserted into the head 30, and the start button 52 of the remote control unit 50 is operated. The unit 20 operates to proceed with each bending to bend, and then press the chucking button 51 to remove the bent cable C from the head 30 and then reset the button of the remote controller 50 ( 53), the bending unit 20 goes to the standby state.

Wherein the frame 10, the PLC (PLC) and the electrical components are installed on the inside and configured to have a power supply and air pressure, the lower portion is provided with a moving means (11), the upper light means (for easy operation) 12) is installed.

The moving means 11 is a moving wheel known in the art is easily installed, the lighting means 12 is a fluorescent lamp.

5 and 11, the bending unit 20 includes a base 21 having a guide 21a disposed below the bed 13 so as to be transportable to the bed 13, and the base 21. A bending power transmission portion 22 installed at an upper portion of the bending power transmission portion 22, a bending portion 23 installed at an upper portion of the bending power transmission portion 22 to grip a cable C, and a predetermined upper portion of the base 21; A cable support unit 24 installed at a predetermined distance from the bending part 23 and supported to support the cable C when the cable C is bent by the bending part 23; It includes a positioning unit 25 provided to move the position of the base 21 by the motor (M) and the ball screw (B).

That is, the bending power transmission unit 22 limits the rotation angle or adjusts the origin point according to the wire diameter, and the bending unit 23 is 45 degrees or 90 degrees by the rotational force transmitted by the bending power transmission unit 22. The bending of the degree is performed.

In this case, when the bending is performed by the bending part 23, the cable support unit 24 moves forward to support the cable to help the cable C bend, and the positioning part 25 includes the ball screw ( It is fastened with B) is configured to move from side to side by the rotation of the ball screw (B).
