DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a deburring device for removing beams from the edges of punched holes in sheet metal, and a sheet metal processing device incorporating this deburring device.

[Conventional technology]

Conventionally, a deburring device for removing a beam formed on the edge of a punched hole in a sheet metal, etc. uses a roller (trailing roller) that brings a driving part with a deburring section at the tip into contact with the sheet metal, etc.
The deburring part was pressed against the burr forming part of the sheet metal.

[Problem to be solved by the invention]

However, conventional devices use a tracing method to make the deburring tool follow the tool, but they do not take into consideration the variation in the degree of burr generation on the workpiece, so the tool may be moved depending on the degree of burr generation. Therefore, there was a problem that the amount of deburring was not uniform.

The above-mentioned device is manufactured separately from, for example, a press processing device, and therefore, it is complicated to move the processed product to the deburring device after press processing, which reduces work efficiency. Ta.

Therefore, the present invention has been made based on such circumstances, and its object is to provide a deburring device that can automatically remove only burrs.

Another object of the present invention is to provide a sheet metal processing device that can be combined with other devices to automatically perform deburring during a series of operations.

[Means to solve the problem]

In order to achieve such an object, the present invention provides a deburring device for removing burrs from the edges of punched holes, etc. formed in sheet metal. means for calculating the distance to the deburring device; means for calculating the distance from the end of the burr on the edge of the punched hole to the deburring device; and the deburring device so that the difference between the respective distances becomes O. The invention is characterized by comprising means for controlling the movement of.

Further, the present invention is a sheet metal processing apparatus in which at least a press processing unit and a tapping processing unit are integrally attached together with the above-mentioned deburring device.

[Effect]

In this way, the distance from the edge of the punched hole in the sheet metal to the deburring device is calculated, and the distance from the end of the burr on the edge of the punched hole to the deburring device is calculated, and the results of these calculations are calculated. By determining the position of the deburring device so that the difference between is O, it becomes possible to remove only the burr without cutting the edge of the punched hole.

Since each of the above calculations and the position control of the deburring device can be performed automatically, it is possible to eliminate the difficulty of manual operations.

Furthermore, since it can be integrated with press processing equipment and tapping processing equipment that are relatively easy to automate,
It becomes possible to automate a series of tasks.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of an embodiment of a deburring device according to the present invention will be described below with reference to FIGS. 1 and 2.

In the figure, there is a sheet metal 1, which is clamped by a workpiece clamping device 2. This work clamp device 2 is moved by a work drive device 2, and is configured to position the sheet metal 1 at a predetermined location.

The sheet metal 1 has a punched hole 4 formed therein and a burr 4A formed around it.

A deburring tool 5 is disposed below the punched hole 4 of the sheet metal 1 positioned at a predetermined location by the workpiece drive device 2, and this deburring tool 5 is moved by the tool drive device 7.
It is designed to be driven by.

Further, a plate holder 9 is arranged around the deburring tool 5 to press down the sheet metal 1 from below, and this plate holder 9 is a plate holder placed above the sheet metal 1. With 8.

The position of the metal sheet 1 is fixed.

A bump 10 is provided on the surface of the plate holder 8 that faces the sheet metal 1, so that the plate 1 can be easily moved under the pressure of the plate holder 8.

Note that the workpiece drive device 2 and the tool drive device 7 described above.
Each drive of the plate presser 7 is controlled by a control device 6.

FIG. 2 is a configuration diagram showing the peripheral portion of the deburring tool 5 in detail. In the figure, the deburring tool 5 is
When taken in a cross section including the central axis, it has a trapezoidal deburring section 5A that is axisymmetric, and this deburring section 5A is rotated by a tool driving device 7. Further, the tool driving device 7 is configured to move upwardly or downwardly along the upward direction during deburring work using the deburring tool 5.
It can be driven.

This vertical movement is driven by a motor 13 and controlled by a Z-axis control device 13 via a drive device 13B. This Z-axis control device 13
The motor 13 is controlled based on a signal from a sensor 11 built into the motor.

The sensor 11 measures the distance @Q from the end of the burr forming part of the punched hole 4 in the sheet metal 1 to the center axis of the deburring tool 5, and this distance Q is determined by the Z-axis controller 13. , is compared with the distance Q' from the edge of the punched hole 4 in the sheet metal 1 (the edge as designed when no burrs are formed) to the central axis of the deburring tool 5. That is, ΔQ=Q-Q' is calculated.

The deburring tool 5 is configured to move up and down so that this value becomes O. The movement amount ΔZ in this case is expressed as follows, when the spread angle of the apex angle of the deburring portion 5A is 0.

If the ΔQ is detected as a positive value, the amount of burr removed is excessive, and large fluctuations in the ΔQ make it impossible to achieve a uniform finish. Further, if ΔQ is detected as a negative value, the deburring section 5A will idle.

From this, by moving the deburring tool 5 up and down,
This is to perform appropriate deburring.

In addition, in the figure, the work clamp device 2 has motors 2A, 2
This drive is driven by the X-Y axis control device 12
The path HQ' is calculated from this drive information and the positional information of the punched hole 4 with respect to the sheet metal 1, which becomes a factor for deriving the calculation result of the ΔZ.

Here, the sheet metal 1 is adapted to be subjected to various tapping processes, and a tool changer 1.8 is provided so that tools can be changed as necessary.

The press processing unit 15 is provided with a product separation processing unit 20 with the deburring device 14 in between.
