Description

Technical Field [0001] The present invention relates to a busbar punching apparatus for fixing and removing an NCT punching machine,

The present invention relates to a punching device for a punching machine, and more particularly, to a punching machine for punching an NCT punching machine for punching through holes in a metal plate, And more particularly, to a bus bar punching apparatus for detaching and removing an NCT punching machine capable of minimizing the facility cost of the apparatus and efficiently processing through holes in a bus bar.

In order to connect terminals and terminals with electrical contacts, a bus bar, which is designed and manufactured in various thicknesses and lengths, is used as a material of an energizable metal plate such as copper or aluminum.

Such a bus bar is mounted according to the design of an electric distribution board or a distribution board, is cut or bent for connection assembly with another member, is punched by punching a plurality of through holes, which are holes for fixing and connecting by bolt tightening with another member Is required.

The booth bar punching apparatus includes a mold for fixing the booth bar, and the booth bar punching apparatus is provided with a processing unit for processing the booth bar. And then presses the punch toward the bus bar.

However, since the conventional booth bar punching apparatus adjusts the punching position of the booth bar in the punching operation, there is a problem that it is difficult to match the work position when the through-hole is machined in the booth bar.

As a prior art disclosed to solve the above problems, Korean Patent Registration No. 785455 (Dec. 2007) discloses a hydraulic cylinder, an upper tool retention base, a lifting rod for guiding upper and lower linear motion of the upper tool retention base, Wherein the upper tool coupled to the upper notch retention base is a punching machine and the lower tool mounted on the lower tool retention base is a fixed plate material, And a guide for guiding a punching position of the booth bar is formed by forming a plurality of fastening protrusions for joining to the plate material, thereby improving the accuracy and efficiency of the punching work.

In addition, in JP-A No. 1485560 (Jan. 16, 2015), a plurality of punching holes having different diameters of holes are provided, and the positions of the punching holes may be rotated for punching holes of a desired diameter. In the rear of each punching hole A rotary punching die having pin holes formed at two positions at right and left sides and formed so as to share one side with each other and corresponding to the number of the punching holes and a hole drilling operation of a desired diameter among the pin holes is performed Two pins that are fitted in two pin holes behind the punching hole located in front of the operator so as to be detachably mounted and a punching hole portion to be punched by the punching operation of the rotary punching die, Shaped member having a vertical support surface and a horizontal surface having a height capable of being held in close contact with the rear surface of the plate member, And a workpiece support base having a length greater than an interval between the outer ends of the two pin holes and being fitted to the two pins and provided with two pin holes on the left and right for mounting on the rotary punching die There is known a rotary punching mold apparatus capable of improving the efficiency of work and increasing the accuracy.

However, since the diameter of the punch is determined in the case of the above-mentioned prior art publication No. 785455, in order to punch a through-hole having a different diameter, a punch tool as a machining means must be replaced, The time is delayed and the productivity is lowered.

In addition, in the case of the above-mentioned prior art Patent Publications No. 785455 and No. 1485560, it is impossible to punch a metal plate having a large area because it is a dedicated and expensive equipment for processing only the through-hole of the bus bar. There is a problem that the cost is increased due to the facility.

On the other hand, the NCT punching machine, which is the main equipment used for the punching of metal sheet materials, is an abbreviation of Numerical (Control) Turret punch press. It is a control method in which the amount of movement of the workpiece is controlled according to numerical information , A punch press which controls a through-hole of various diameters in a batch processable manner and constitutes a numerical control apparatus incorporating a high-speed CPU.

However, since the volume of the bus bar is relatively small in comparison with a conventional metal plate when punching the bus bar from the structure of a general NCT punching machine, the structure in which the bus bar is clamped during processing is interfered with the punching configuration, There has been a problem that a punching device dedicated to a bus bar must be provided in addition to the NCT punching machine for punching the bus bar.

It is preferable that the clamping means 125 is structured so as to have a plurality of clamping portions 125 at regular intervals in the Y axis direction of the feeding unit 120 so as to stably support the workpiece P. [

The punch unit 130 is for punching a through hole in the workpiece P supplied from the feeding unit 120 and moves the punch 135 having a predetermined diameter to raise and lower the workpiece P .

The punch unit 130 includes a plurality of punches 135 for punching the through holes by striking the workpiece P with different diameters. That is, a plurality of punches 135 are selectively applied to the punch unit 130 so that the diameter of the through holes to be punched can be set to various sizes, thereby punching the workpiece P toward the workpiece P.

Since the control structure of a general NCT punching machine can be applied to control the drive of the punching unit 130, the detailed description will be omitted.

The booth pants unit 200 performs a function of fixing and supporting the bus bar of the workpiece P from the punch unit 130 so as to be capable of punching work.

The pressurizing jig 223 is connected to the jig driving unit 230 and is linearly reciprocated forward and backward. That is, the pressing jig 223 flows by the force transmitted from the jig driving part 230 to fix the bus bar in contact with the pressing jig 223.

As shown in FIG. 5, the fixing jig 221 and the pressing jig 223 are each provided with a contact support surface 225 formed on the contact surface of the bus bar.

The contact support surface 225 is formed in a sectional shape having a gentle curved surface corresponding to the side shape of the bus bar to be punched.

The fixing jig 221 and the pressing jig 223 are coupled to each other on the base plate 210 and the jig driving unit 230, respectively. The fixing jig 221 is replaceable from the base plate 210 so that the contact supporting surface 225 can be applied corresponding to the side shape and thickness of the bus bar serving as the workpiece P and the pressing jig 223 Is configured to be replaceable from the jig driving unit 230. [

The jig driving unit 230 is provided on the base plate 210 and drives the pressing jig 223 of the locking jig 220 so as to transmit the gripping pressure.

The jig driving unit 230 includes a moving frame 231 movably mounted on the base plate 210 and drivingly connected to the moving frame 231 to apply power for rectilinear movement. And a cylinder 233. 6, when the driving cylinder 233 is extended and linearly moves the flow frame 231, the pressing jig 223 moves toward the fixing jig 221 to move the bus bar So that the bus bar is fixed from the locking jig 220 in a floating state.

The flow frame 231 extends forward through the fixing jig 221 and has one end connected to the side end of the pressing jig 223.

The flow frame 231 may be configured so as to be coupled to the opposite ends of the fixing jig 221 so as to guide the linear movement of the flow frame 231 due to the power transmission of the drive cylinder 233 It is possible. The fixing jig 221 has a groove 232 extending in the longitudinal direction on the inner surface of the flow frame 231 in contact with the fixing jig 221, It is possible to have the guide pieces 222 protruding from both ends of the jig 221. [

The jig driving unit 230 includes guide means 235 formed between the flow frame 231 and the fixing jig 221 for guiding the linear movement of the pressing jig 223 by the flow frame 231, .
