Description
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.
