Description

Technical Field [0001] The present invention relates to a bus bar fastening hole machining method and a machining apparatus using the same,

The present invention relates to a bus bar fastening hole processing method for forming a fastening hole in a booth bar to be applied to various power distribution equipment and distribution boards, Completion of the machining data by selecting the coordinate pattern enables easy operation even for the unskilled, reduces the machining errors, and greatly reduces the machining time because it is easy to input the machining coordinates. And more particularly, to a method of machining a fastening hole of a bus bar and a machining apparatus thereof.

As is known, a high-purity water distribution device, a distribution board, and other wiring is made of a copper material that is rolled and drawn with a high-purity material to efficiently deliver large current with a large conductor cross-sectional area in consideration of electrical resistance.

The bus bar is excellent in electrical conductivity and bending workability and is free from defects in use and is usually in the form of a plate-like stick having a rectangular cross-section.

The bus bar is formed by bending a necessary fastening hole on the board in consideration of the case of wiring to connect between a specific electric equipment and equipment, the case of branching from the wiring and connecting to another wiring, And the completed busbar can be made in a wide variety of ways depending on the design of the application.

Therefore, the perforation of the fastening hole in the busbar differs for each application and design.

These booth bars have a cross-sectional thickness of 4mm ~ 15mm according to the capacity of the electric facility. It is virtually impossible to bore or bend them arbitrarily at the facility site. The booth bar is manufactured and supplied by bending process through a dedicated press- The machined busbars are used in the field to complete the wiring by bolting through only the fastening holes.

A machining apparatus for punching a fastening hole into a bus bar as described above is also known in the art.

In general, there is a manual type in which a worker manually sets a jig according to a punching position, and then supplies the booth bar material to the jig and drives the punching machine to drill holes.

However, there is a disadvantage that the position of the jig must be changed according to the specifications such as the position and the number of the punching holes and the length of the bus bar, and the booth having a heavy weight The bar is manually handled, punching is performed, the productivity is extremely low, and if the jig is mispositioned, there is a problem of mass production of defective products, which is a disadvantage of requiring a highly skilled and highly concentrated worker.

An NC punching device by computer numerical control has been developed and known to solve the problems of the manual punching device as described above.

A punch assembly 202 having a plurality of punches having different sizes on the main body, a punch assembly 202 having a main body 200 fixed to the ground as shown in Fig. 1, And a take-out clamp 205 which constitutes an take-out bed 203 for taking out the machined busbar and a take-out clamp 205 for constituting an inlet clamp 300 for clamping the workpiece on the transfer bed 201 side There is known a machining apparatus including a control device that controls all processes of machining by making a fastening hole with a punch assembly while changing a machining position by linearly moving a workpiece with a clamp.

According to the prior art, a computer numerical control machine (CNC) is operated by a numerical control program. Therefore, a skilled NC programmer is required, and an NC programmer is required to program a part program shall.

In such a booth bar connection hole processing device, the part program is written by the operator using the editor provided by the CNC, and the operator inputs the combination of characters and numbers by using the keys of the MDI (Manual Data Input) operation panel .

For example, as shown in FIG. 2, which is a conventional input method, absolute coordinate values in the X and Y-axis direction of each fastening hole must be manually input using one side edge of the workpiece as a machining origin.

In order to drill 22 fastening holes, it is necessary to input position coordinate value of 44 times which is multiples thereof.

When all of the individual position coordinate values are inputted, the machining position of each fastening hole is set with reference to the machining origin of the side bar as the work material as shown in Fig.

After inputting the individual position coordinate values, an additional step of selecting and inputting the machining punches by a separate process is required.

Therefore, since the operator directly programs the part program using the keys of the MDI operation panel, the operator can operate the part only if he or she fully understands the program commands for all the processing patterns and the processing conditions and processing conditions according to the processing pattern.

Therefore, when the skill level of the operator is low, the machining program must be programmed while confirming the program commands individually, and even if the skilled worker accidentally inputs the command by mistake, the machining can be undesired by the operator.

In addition, conventionally, when a machining program is created, a machining pattern and a command for the machining parameter must be input by the author in a combination of letters and numbers, so that it takes a lot of time to input the machining shape to be machined.

This is especially true when inputting to complex workpieces.

As a result, in the conventional machining method using the busbar fastening hole processing apparatus, it is essential to carry out the modeling work using the designed CAD data and input the processed modeling information (data file) as the machining data. There is a problem that the operation depends on a highly specialized operator.

At the same time, considering the number distribution system in which the bus bar is used, even if it is a specialized worker, the operator has to repeatedly perform manual work such as inputting a lot of modeling information and selecting a machining order and a machining tool, There is no problem.

See FIGS. 5, 6 and 7-11.

The storage device 22 of the numerical control computer 20 includes a pattern DB 26 and a process DB 24 and stores the operation result of the numerical control device 21 as data.

That is, a unit pattern or a process setting is performed by a unit pattern setting confirmation step of selecting a setting path of an external input state as a unit pattern or a process setting from the setting step (S200) of the control step through the interface device (30) Is selected.

The unit pattern is formed by bundling a plurality of adjacent fastening holes into one unit.

The unit pattern setting is to set the machining datum point (X, Y) of the unit pattern that selects a specific point centered between each hole for a unit pattern for various patterns such as 4 holes or 6 to 8 holes as a numerical value And inputs the position of each of the fastening holes included in the unit pattern to finish inputting the unit pattern coordinates, and records the completed unit pattern in the pattern DB 26 of the numerical control computer to complete one unit pattern.

For example, as shown in Fig. 7, relative machining coordinates are input from the machining datum coordinates (0, 0) to the position values as shown in the pattern machining data table of the unit pattern groups NO.01 to NO.04.

7A shows a unit pattern constituting six fastening holes. When a relative machining coordinate value for six holes is inputted in the pattern machining table based on the machining reference point coordinate, one unit pattern input operation is completed do.

Next, the process of setting the process will be described with reference to FIG.

When the process setting is performed in the unit pattern setting confirmation step, the length and width standard of the machining unit booth bar are inputted as numerical values. The position value of the process setting is inputted as numerical value, and one corner of the machining initial portion Enter the relative numerical value spaced from this origin as the machining origin.

That is, with respect to a unit product section of a predetermined length for a long-length bus bar workpiece, a position value spaced in the X and Y-axis directions based on the processing origin is set as a process reference point, Is shown in FIG. 01 ~ NO. 04 is numerically controlled so that the processing reference point coordinates of the unit pattern up to 04 coincide with the process reference point.

For example, by inputting the machining reference points of the respective process settings in the X and Y axis directions as numerical values and inputting the group (unit pattern) numbers to be machined to be superimposed on the process reference points as in the process setting data table, The specific unit pattern data is combined with the specific process reference point, and the process data input is ended so that the process of joining holes is performed at the corresponding position.

Therefore, by combining one unit pattern data of all the unit patterns in the process setting data table, it is possible to easily perform various fastening holes.

Such a process setting can be stored in the process DB 24 of the storage device, loaded, and ready for machining, thereby improving productivity.

9, the numerical control computer 20 for processing inputs the position values (X, Y) of each fastening hole as shown in the display device for inputting and storing the unit pattern, finishes the pattern input, The shape of the currently input unit pattern is visually displayed.

Fig. 10 shows a display device for setting a process. The display device is used to select a position (X, Y) of a process reference point spaced from the origin of the workpiece and a mold (punch) for punching the fastening hole, And the number of unit patterns can be selected. These process settings can be selected by number and selected.

If a mode is selected for automatic production, a process number is requested in step S110, and if a process setting number is input through the monitor of the display device as shown in FIG. 11, the unit pattern is overlapped with the unit bus bar shape, This screen allows the operator to start production.

Of course, as is well known, the workpiece is made of several meters of material in the longitudinal direction, and the long material is supplied sequentially, and the unit booth is cut and produced.

Therefore, it is possible to automatically produce overlapping unit patterns repeatedly for the positions set in each booth bar, and as a result, all the fastening holes for one bus bar product are input one by one, and when the product production type is changed, The present invention is characterized in that a fixing hole forming a predetermined position is formed and stored as a unit pattern, a point at which each unit pattern is positioned is set as a process reference point, and a process reference point It is possible to maintain the high productivity by eliminating the number of cases in which errors are caused irrespective of the skill of the worker and the inputting of the operation positions of many fastening holes becomes easy by overlapping the coordinates.
