Description

Apparatus for bending crime prevention and insect protection net

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a security screening bending apparatus, and more particularly, to a security screening network bending apparatus for bending a rim of a net used in a security screening network at a required angle.

In the case of low-rise buildings or apartments, a security window is installed in order to prevent unauthorized entry from outside through windows, or an insect screen is installed to prevent ventilation or inflow of insects.

Such a security screening network may have a structure as shown in FIG.

The security screening security net includes a window frame 1, a fixed frame 2 inserted into the insertion channel 1a formed in the window frame 1, and a bending state between the insertion channel 1a and the fixed frame 2 And a netting 3 interposed therebetween.

At this time, the bottom of the insertion channel is formed to be inclined so as to prevent the detachment of the net, and the ends of the fixed frame inserted into the insertion channel also form a corresponding inclined surface, so that the net is tightly fixed between the inclined surfaces in a bent state.

The bending angle of the net is formed at an acute angle smaller than 90 degrees so that even if an external impact is applied to the net,

However, in order to fabricate such a net, it is necessary to bend the rim in accordance with the inner shape of the insertion channel.

Normally, the netting is generally made of steel or stainless steel metal with good strength, so it is difficult to bend unless a separate tool is available.

Particularly, since it is necessary to bend a narrow region of the rim instead of the center which is relatively easy to bend, it is required to develop a net bending apparatus capable of effectively performing such a work.

The rotating cylinder 220 may be horizontally installed rearwardly from the front of the net mounting plate 110 and the bending member 210 may be vertically coupled to the rod 220a.

At this time, a rectangular beam or square pipe-shaped gap retaining hole 230 is attached to the plate surface of the bending member 210 and a hinge member 240 (see FIG. 2) is inserted between the gap retaining hole 230 and the rod of the rotating cylinder 220. And a rod 220a of the rotary cylinder 220 is rotatably connected to the gap holding hole 230. [

It is needless to say that the gap holding tool 230 may have another shape or structure that can maintain a predetermined gap between the bending member 210 and the rod.

The rotary cylinder 220 is installed on the work table 100 and is rotatably installed.

It is important that the eccentric rotation means 250 is provided between the bending member 210 and the vertical frame 120 because the bending line BL must be rotated about the rotation center when the bending member 210 rotates desirable.

At this time, the axis of the rotation shaft 253 coincides with the bending line BL.

Accordingly, when the rotating cylinder 220 is driven, the bending member 210 rotates about the bending line BL. When the bending member 210 rotates, the upper surface of the net mounting plate 110 and the bending surface 210a (Angle of less than 180) with respect to the upper surface 110a of the nettle mounting plate 110 while the bending surface 210a is rotated on the same plane (forming 180 degrees with each other).

For example, a bearing may be provided in the fixture, the rotation axis may be coupled to the eccentric angle, the bearing may be inserted into the eccentric angle, and the rotation axis may be coupled to the fixture.

Next, the net position alignment unit 300 will be described.

To this end, the mounting frame 130 may be provided with a mounting bracket 340, and the mounting plate lifting cylinder 310 may be installed on the mounting bracket 340.

A plate-like alignment plate 320 may be coupled to an end of the rod 310a of the alignment plate lifting cylinder 310 to move up and down.

The alignment plate 320 has a predetermined thickness and is mounted horizontally. The alignment plate 320 is lowered and seated on the bending surface 210a of the bending member 210.

At this time, the front end of the alignment plate 320 is preferably mounted on the bending surface 210a. The step 320a may be formed at a height corresponding to the thickness of the alignment plate 320 so that the step 320a of the alignment plate 320 when the netting N is mounted on the bending face 210a, The netting N is caught and aligned.

On the other hand, an alignment plate guide post 330 may be provided on the mounting bracket 340.

That is, a pair of alignment plate guide posts 330 are provided on both sides of the alignment plate lifting cylinder 310, and a lower end thereof is engaged with the alignment plate 320 to guide the alignment plate 320 have.

Of course, one or more alignment plates 320 may be provided, and at least one alignment plate elevating cylinder 310 may be provided correspondingly.

Next, the fixing unit 400 is configured to vertically pressurize and fix the netting N mounted for the bending operation on the net mounting plate 110 before bending the netting member N. The pressing member lifting cylinder 410, (420) and a pressing member guide post (430).

The pressurizing member elevating cylinder 410 is vertically mounted on the mounting frame 130 and is installed on the upper side of the workbench 100 and has a rod 410a facing downward.

The pressing surface 420a presses the net N and the bending inclined surface 420b is a portion that determines the bending angle while the netting bent by the bending member 210 is closely attached.

In the present invention, the edge bending angle of the net N is formed such that the bending slope 420b has an acute angle in order to make the edge angle of the net N be acute.

Herein, the angle of bending of the bending inclined surface 420b may be adjusted by changing the pressing member 420 or by changing the pressure member of another kind.

A pressing member guide post 430 for guiding the lifting and lowering of the pressing member 420 is provided at one side of the pressing member lifting cylinder 410 and is engaged with the pressing member 420.

Hereinafter, the process of bending the netting by operating the present invention will be described with reference to FIG.

First, the net position alignment unit 300 is operated (refer to FIG. 6A)

That is, when the aligning plate lifting cylinder 310 is driven to lower the aligning plate 320, the aligning plate 320 is lowered to the bending face 210a of the bending member 210, Stop.

At this time, one end of the lower surface of the alignment plate 320 is slightly extended to the bending surface 210a.

Next, the operator puts the netting N to perform the work on the net mounting plate 110 and pushes the netting N toward the aligning plate 320 side. At this time, the edge of the net N is aligned so as to be in close contact with the step 320a of the alignment plate 320.

In this state, the fixing unit 400 is operated (see FIG. 6B)

That is, when the pressing member 420 is lowered by driving the pressing member lifting cylinder 410, the pressing member 420 is lowered to the backing plate 110 and is mounted on the backing plate 110 And then stops the descent automatically. At this time, the end of the pressing surface 420a of the pressing member 420 coincides with the end of the nettle plate 110, and the netting member N is pressed. In other words, to conform to the bending line BL.

As soon as the pressing member fixes the net N, the aligning plate 320 ascends and returns to its original position.

Next, the bending unit 200 is operated (see FIG.

When the rotating cylinder 220 of the bending unit 200 is driven, the bending member 210 starts to rotate. Accordingly, the bending member 210, which is positioned on the same plane as the upper surface of the net- ) Are inclined while rotating.

The netting N fixed to the bending surface 210a starts to bend with respect to the bending line BL pressed by the pressing surface 420a. The bending member 210 is rotated until the bending surface 210a is in close contact with the bending inclined surface 420b of the pressing member 420,

Finally, the net N is bent at an angle (acute angle) equal to the inclination angle of the bending inclined surface 420b.

Then, the pressure member lifting cylinder 410 is moved backward, the pressure member 420 is lifted, and the bent member is recovered when the pressure member 420 is retracted.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention may be embodied in many other specific forms without departing from the spirit or essential characteristics thereof.
