{AUTOMATIC BUSBAR BENDING MACHINE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bending apparatus for automatically bending and processing a busbar used for delivering a comparatively high voltage current in a switchboard to a desired shape.

One of the forms typically used in a busbar bar used in an ASSEMBLY takes the form of a bar bent in a trapezoidal shape as shown in FIG.

In the conventional method of manufacturing the bus bar 1, a straight bar is drawn into a metal mold manufactured according to the length and bent angle of the bent portions 1a, 1b, etc. of the bus bar 1, .

However, since the booth bar 1 is custom-made with different lengths and angles by the bent portions 1a, 1b, etc., depending on the use and the use place, There was an inconvenience that a new mold had to be manufactured each time the dimensions were changed.

Accordingly, it is an object of the present invention to provide an automatic bending apparatus for a bus bar for a switchboard which can be applied to a case where detailed specifications of the bus bar vary.

According to an aspect of the present invention, there is provided a motor control apparatus comprising: an LM driver configured to adjust a drawing amount of a straight bar to be molded in accordance with rotation of a motor; A lower bending portion for pressing the straight line bar in the upward direction to adjust the amount of bending; An upper bending portion for adjusting the amount of bending by pressing the straight bar in a downward direction; A cutting unit for cutting a straight bar that has been inserted and bent and necessary for the unit bus bar to cut off the bus bar; An input unit for inputting a detailed specification of a desired bus bar; And a control unit for controlling the LM driver, the lower bend, the upper bend, and the cutting unit according to a detailed specification of the bus bar input to the input unit.

Here, the lower bent portion and the upper bent portion are symmetrically arranged up and down with reference to a passing point of a straight bar drawn by the LM driver, and the lower bent portion is formed in a portion of the straight bar positioned on the passing point And the upper bent portion is reciprocally slidably driven from the upper portion to the lower portion with respect to the portion of the straight line bar located on the passing point.

The LM driving unit includes a lead screw extending to the other opposite end with one end of the passing point, a driving motor coupled to the other end of the lead screw to rotate the lead screw in normal and reverse directions under the control of the controller, And an LM guide that slides in the forward and backward directions in accordance with normal and reverse rotation of the lead screw and fixes one end of the straight bar.

As described above, according to the bus bar automatic bending apparatus for an electric distribution panel according to the present invention, when the detailed specifications of the bus bar are input through the input unit, the LM driver, the lower bend, the upper bend, The booth bar of the desired specification can be automatically formed by the part.

6A to 6G are enlarged views for explaining the operating process of the bus bar automatic bending apparatus for the switchboard of FIG.

As shown in FIG. 2, the automatic bus bending apparatus 100 for a switchboard according to an embodiment of the present invention includes an LM driver 110 installed on a fixed base 101, A cut portion 140 provided adjacent to the lower and upper bent portions 120 and 130 and a cutout portion 140 formed in the vicinity of the upper and lower bent portions 120 and 130, And an input unit 150 for inputting a specification.

The LM driving unit 110 includes a lead screw 111 extending in the left and right longitudinal direction and rotatably supported and a driving motor 112 coupled to one end of the lead screw 111 to rotate in the normal and reverse directions, And an LM guide 113 slidable along the lead screw 111 in the forward and backward directions (i.e., left and right).

One end of the straight bar 2 to be molded is fixed on the LM guide 113.

The driving motor 112 is rotationally driven under the control of a control unit 160 of FIG. 6 described later so that the lower bent portion 120 and the upper bent portion 130 of the straight bar 2, one end of which is fixed to the LM guide 113, The amount of the drawing to the passing point that forms the space between the two ends is adjusted.

3, the lower bending portion 120 is a portion of the straight bar 2 disposed below the passing point P of the straight bar 2 and positioned at the passing point P with respect to the passing point P of the straight bar 2, And a lower hydraulic cylinder 122 for reciprocally driving the lower bending blade 121 to the lower base position (position in FIG. 3) and the upper pressing position (see FIG. 6B) ).

The upper bending part 130 is disposed on the upper side with respect to the passing point P of the straight bar 2 and is symmetrical with the lower bending part 120. The straight bending part 130, The upper bending blade 131 presses the upper portion of the upper bending blade 131 in the downward direction and bends the upper bending blade 131 to the upper position, And a cylinder 132.

2, the cutting portion 140 includes a cutting blade (not shown) which is disposed adjacent to the upper bending portion 130 and is driven to move up and down by a hydraulic cylinder 141. [ The cutting portion 140 cuts the other end of the straight bar 2 that has been bent to the unit bus bar 1 in FIG. 1 by the lower bent portion 120 and the upper bent portion 130, So that the bus bar 1 is removed.

The input unit 150 displays the bus bar image 1 '(a simplified model of the bus bar 1 in FIG. 1) on the screen of the touch panel 151 as shown in FIG. 4, '), That is, the length of each part and the angle of connection. The detailed specification is provided so that it can be inputted and corrected by a user's touch.

Accordingly, the user can input the detailed specifications of the desired booth bar through the input unit 150 and then automatically press the 'run' button to form the boom bar 2 according to the detailed specifications to produce the booth bar by the input amount .

5, detailed specifications inputted through the input unit 150 are transmitted to the controller 160 and are transmitted to the LM driver 110, the upper bend unit 130, the lower bend unit 120, Step-by-step sequential control of the unit 140 is performed.

6A) of the straight bar 2 drawn by the LM driving part 110 to the passing point P is set (refer to FIG. 6A), when the lower bending part 120 is driven The bending blade 121 rises to press and bend the straight bar 2 (Fig. 6B). At this time, an angle (see? In Fig. 1) bent according to the degree of elevation of the bending blade 121 is determined.

When the LM driver 110 is driven to set an additional pulling amount of the straight bar 2 (see 1b in FIG. 1) (FIG. 6C), the bending blade 121 is raised So that the straight bar 2 is pressed and bent (FIG. 6D).

Next, when the linear bar 2 is drawn by the amount of the additional lead (see 1c in Fig. 1) by driving the LM driver 110 (Fig. 6E), the upper bending part 130 is driven, Is lowered to press and bend the straight bar 2 (Fig. 6 (f)).

The LM driving unit 110, the lower bending unit 120 and the upper bending unit 130 are driven in accordance with the control by the control unit 160 as described above to move the linear bar 2 from the unit When the booth bar 1 'is formed, the straight bar 2 is cut by the driving of the cutter 140, so that the unit booth bar 1' is removed and the product is completed.

Then, the above process is continuously performed to form the desired number of bus bars 2 inputted to the input unit 150.
