It is suitable for large-sized small parts and has excellent advantages in the operation of the iron plate because the automatic punching operation by the CNC program is possible. It is possible to work according to the weight, the circuit is complicated and expensive, dimensional error occurs due to the cutting error of the iron plate, and the program is complicated and requires some skill.

The manual punching machine is a portable type of punching worker who carries the punching work at the desired position. The punching head part and the hydraulic pump part are separated from each other and the movement is inconvenient. If it is not constant, there is a dimensional error, marking work becomes necessary, and since the marking, preliminary punching, punching, and the like must be performed, the work speed is slowed and the production amount fluctuates depending on the skill of the skilled worker or the worker .

The automatic section steel drilling machine is a machine that measures the length after fixing the machine body and measures it with the measuring roll, and then moves the section steel to perform the drilling operation. The material loss is caused by the problem of the fixed part of the end part, the productivity is drastically decreased by drilling, There is a disadvantage that the equipment (drill grinders, etc.) is increased, only an expert can work, consumption of consumables is high, and dimensional error is severe depending on the shape of the steel section.

As a background of the present invention, Korean Unexamined Patent Publication (Kokai) No. 1985-0007363 discloses an XY table apparatus for conveying and moving a workpiece, and an XY table apparatus for driving the XY table apparatus to set the workpiece at a predetermined position A mold drive means for driving the mold means, and a drive means for driving the mold means, wherein the mold driving means includes a lower mold set and a lower mold set, And a punching device for forming at least one through hole in the workpiece is proposed.

In the background art, a punching hole is automatically formed by setting a punching position by moving a table with a servomotor. However, in the background art, there is a problem that the movement amount of the table is limited, so that the material of the workpiece can not process the hole in the long beam or the section steel, and there is a limit that all holes can not be machined on the upper and side surfaces of the work.

At this time, the punching machine carriage 40 waits at the end of the punching process conveyor 20 (the position where the punching process is started at the right end in Fig. 1) and punches the punching dies 521a and 521b of the vertical punching machine 50, Is located inside the lower beam 3 as shown in FIG.

Then, the reference surface to be punched is set. This can be done through a position gauge (not shown) installed on the front face of the vertical punching block 52. The reference gauge is held at the starting end of the lower beam (3).

Then, after selecting the 'top surface' button on the control panel (not shown) provided on one side of the punching machine carriage 40, the work speed, product length, end / length, hole quantity, .

When the operation is started, the punching machine carriage 40 is moved to the set position and the vertical punching cylinders 53a and 53b of the vertical punching machine 50 are sequentially lowered and operated to move left and right sides of the upper surface of the lower beam 3, And the right upper surface holes 3a and 3a are machined. When the vertical punching cylinders 53a and 53b are lowered, the punching punches 531a and 531b exert shearing force in cooperation with the punching dies 521a and 521b, respectively.

At this time, after the punching operation, the vertical punching machine 50 returns to the middle position of both holes. This return operation is performed by the position cylinder 70 of Fig. 6C, which feeds the vertical transfer board 51 in the punching machine carriage 40, and also by the operation distance of the position cylinder 70, The distance of the hole is determined.

In the loading section 12, the loading-side driving motor 109 is driven together with the processing-side driving motor 24 to receive the lower beam 3 from the workpiece processing section 11 by the loading-side transfer roller 104.

9B, the take-out cylinder 108 is actuated to lift the take-out arm 106 to one side of the stacking stand 200 (see FIG. 9B) . Therefore, the lower beam 3 is tilted to one side by the take-out arm 106, slid by its own weight, and moved to the stacking table 200 to be stacked.

Thereafter, the punching machine carriage 40 returns to the initial position and waits for machining.

<Top beam hole processing>

First, the upper beam 2 waits at the standby portion 10 in the same manner as the lower beam 3, and is conveyed to the workpiece processing portion 11 through the same means.

Then, when the upper beam 2 is transferred to the workpiece machining portion 11, the clamp cylinder 31 is operated as shown in FIGS. 5A and 5B to narrow the gap between the movable jaw 32 and the fixed jaw 33 The upper beam 2 is fixed. At this time, the portion to be punched in the upper beam 2 is placed on the horizontal punching die 621 side of the horizontal punching machine 60 as shown in Figs. 6B and 8A.

Then, the reference surface for punching the upper beam 2 is set. This can be done through a position gauge (not shown) installed on the front of the horizontal punching block 52. The reference gauge is held in alignment with the starting end of the upper beam 2.

Then, the operator selects the 'side' button in the same control unit, and sets the operation speed, the product length, the end / length, the number of holes and the distance between the holes, and then starts the operation.

Thereafter, the punching machine carriage 40 is moved to a predetermined position on the reference surface of the upper beam 2 by driving the driving motor 42 for reciprocating carriage, and then the horizontal punching hydraulic cylinder 63 is operated to move the upper beam 2 , The side holes 2a are machined as shown in Fig. 8A. When the horizontal punching hydraulic cylinder 63 is operated, the horizontal punching punch cooperates with the horizontal punching die 621 to exert a shearing force.

When the punching hole is machined in the upper beam 2 for the first time, the punching machine carriage 40 repetitively performs the set pitch transfer, and the horizontal punching hydraulic cylinder 63 is operated each time the pitch transfer is completed, . At this time, the conveyance of the punching machine carriage 40 is performed by driving the reciprocating conveying drive motor 42.

Then, when the hole punching of the upper beam 2 is completed, the machining-side driving motor 24 is driven and the upper beam 3 is discharged by the machining-side machining-side transfer roller 22 to the loading part 12 do.

In the loading section 12, the loading-side driving motor 109 is driven by the article-taking-out apparatus 100 together with the working-side driving motor 24 so that the upper beam 2 is subjected to workpiece machining (11).

9B, the take-out cylinder 108 is actuated to lift the take-out arm 106 to one side of the stacking stand 200 (see FIG. 9B) . Therefore, the lower beam 3 is tilted to one side by the take-out arm 106, slid by its own weight, and moved to the stacking table 200 to be stacked.

Thereafter, the punching machine carriage 40 returns to the initial position and waits for machining.

As described above, according to the present invention, compared with the conventional steel plate universal machine in which punching is performed by moving the steel plate, the vertical punching machine 50 and the horizontal punching machine 60 are moved to position the holes to limit the size and weight of the material , Free dimensional movement is minimized by free movement even when the shape of the material is bent, and automatic hole processing is performed by inputting the length of the material, so that skilled workers are unnecessary, and it is suitable for both small and large-sized large-sized varieties.

Further, as compared with a mobile manual punching machine in which a worker carries a punching job at a desired position, a marking operation is unnecessary and the work speed is improved.

In addition, compared with automatic section steel drilling machines that move drilling operations by moving a steel frame after fixing the machine body, the material clamping is made entirely and there is no material loss, productivity is improved by more than 10 times by punching work, There is no need, and if you learn how to use it, beginners can work, and the cost of consumables is small.
