The hydraulic device drives a hydraulic pump with a prime mover, converts mechanical energy into fluid energy of oil, and freely controls the pressure, flow rate and direction of oil by a hydraulic control valve, so that the mechanical movement or work is performed by an actuator. It is a series of devices.

On the other hand, the present invention may further include an unloading unit (not shown) for placing the cut wiring duct.

The action of the wiring duct cutting device of the present invention configured as described above is as follows.

In order to manufacture the switchgear, the wiring duct 1 should be cut to a desired length. First, the wiring duct 1 is loaded into the loading unit 100 of the wiring duct cutting device.

That is, the wiring duct 1 is placed on the guide 110 having the V-shaped groove of the loading unit 100. The wiring duct cutting device of the present embodiment is a cutting device having a structure capable of simultaneously cutting wiring ducts of various standards. Accordingly, since the size of the guide 110 is different according to the wiring duct standard being raised, the wiring duct corresponding to the size Put it on.

In this state, the wiring duct 1 seated on the guide 110 of the loading unit 100 is guided by the guide 110 so as to be transferred toward the cutting unit 300.

At this time, the cutter fixing part 310 and the cutter movable part 320 constituting the cutting unit 300 are formed with through holes 310a and 320a through which wiring ducts 1 can pass. The duct 1 passes through both the cutter fixing part 310 and the through holes 310a and 320a of the cutter moving part 320.

The wiring duct 1 continuously transferred past the through holes 310a and 320a is prevented from advancing further by contacting the stopper 210 installed in front of the cutting unit 300. That is, when the contact with the stopper 210 results in setting the cut length of the wiring duct 1, the position of the stopper 210 constituting the positioning unit 200 as described later. Adjust and set the desired cutting length.

Meanwhile, as described above, the cutter duct 310 and the wiring duct 1 passing through the through holes 310a and 320a of the cutter movable part 320 move by the set cutting distance, and then the interference of the stopper 210 is moved. In the stopped state (refer to FIG. 9), when the operator presses the foothold 350 for operating the switch to operate the hydraulic device 340, the cutter moving part 320 interlocking with this is lowered, and thus the wiring duct 1 ) Is cut (see FIG. 10).

At this time, the edges of the through holes 320a and 310a formed in the cutter movable part 320 and the cutter fixing part 310 serve as cutting edges, and the cutter movable part 320 has two edges when lowered. The guide plate 330 and the guide block 310b and the guide hole 320b supporting the central portion are exactly linear movement.

Here, the guide 110 is a structure having a V-shaped groove so that the wiring duct 1 is positioned in an inclined state, and thus the cutting force is evenly distributed when the cutter fixing part 310 for cutting is lowered to make the cutting easier. You lose.

At this time, the through hole 310a of the cutter fixing part 310 serves to hold the wiring duct 1 due to its depth.

In particular, the cutting device of the present invention, unlike the conventional straight cutting blades, since the through-hole 310a (320a) itself of the cross-sectional shape of the inclined wiring duct 1 also serves as a cutting blade, the cutter movable part 320 of Even if the falling distance L is not large, the wiring duct 1 is cut (see FIGS. 11 and 12).

That is, in the cutting device of the present invention, the cutter moving part 320 and the cutter fixing part are not even lowered because the cutter moving part 320 is not lowered to the position where the through hole 310a of the cutter fixing part 310 is exposed. The cutting operation is substantially performed by the relative displacement of 310).

On the other hand, immediately after the cutting of the wiring duct 1 is made, the cutter fixing portion 310 is raised to the original position to wait for the next cutting operation.

At the same time as the operation is completed, the operator can take out the cut product, and may be placed in a separate unloading unit after taking out.

Here, the stopper 210 is to set the cutting length (L) of the wiring duct (1) by moving back and forth along the moving direction of the wiring duct (1) can be adjusted by cutting the length (L) of the product arbitrarily. Will be.

That is, when adjusting the cutting distance, the pinion 240 is rotated on the rack 230 by rotating the positioning handle 280 while the fixing bolt 270 is loosened so that the pinion constituting the positioning unit 200 is movable. While moving the), and check the scale of the position measuring instrument 220 installed next to the rack 230, when reaching the position corresponding to the desired cutting length, tighten the fixing bolt 270 to prevent the movement of the rack 230 By adjusting so that the fixed position of the stopper 210 is adjusted.

On the other hand, the guide member 310c is installed around the through hole 310a of the cutter fixing part 310 so that the wiring duct 1 enters the through hole 310a of the cutter fixing part 310. It is guided well without departure and helps to enter the through hole 310a normally.

In addition, the cutter fixing part 310 and the cutter movable part 320 of the present invention is a plate shape, and the thickness thereof is preferably determined so that the depth of the through holes 310a and 320a is at least 0.5 cm, which is for wiring. This is because the duct (1) contains a dust component to give a flame retardant (防 炎) performance, so if you use a regular blade, the blade must be replaced frequently.

That is, the cutter fixing part 310 and the cutter movable part 320 of the present invention should be secured to some extent in terms of durability due to the product characteristics of the wiring duct 1 to be cut.

As described above, the present invention not only improves workability by accurately and effectively cutting several wiring ducts having the same or different specifications to the set length at the same time, but also in cutting wiring ducts for manufacturing switchgear. Durability and safety will be able to be firmly increased.

On the other hand, the present invention is not limited to the above embodiments, and various changes and modifications can be made in various forms without departing from the scope of the technical spirit of the present invention.

For example, the cutting unit 300 of the present invention is a cutter having a through hole 310a, 320a, but is composed of a chisel 310 and a cutter moving part 320, but is not necessarily limited thereto. That is, the through hole 310a is formed only in the cutter fixing part 310, and the cutter moving part 320 is a guillotine type, in which the through hole 320a is not formed, before the cutting operation of the cutter fixing part 310. It may be configured to be positioned on the wiring duct 1 passing through the through hole 310a, and then lowered during the cutting operation to cut the wiring duct.

In addition, the configuration can be changed to operate by hand, such as a switch operation button, instead of the switch operation step for operating the hydraulic device.

The present invention is a useful invention having a high industrial applicability since the wiring duct is cut along the required length to be used for the production of distribution boards (eg, distribution boards, low voltage boards, high voltage boards, MCC panels, integrated panels, enclosures, etc.). .

That is, the present invention can easily cut the wiring duct to the desired length when manufacturing the switchgear, and can simultaneously cut products of various standards, thereby improving work efficiency and productivity, and improving quality and safety. The invention is extremely industrially available in terms of improving the working environment, such as protecting workers from the risk of an accident.
