Abstract

A punching system adapted to punch a sheet metal includes a platform, a punching portion, a base portion and a turret device. The punching portion is disposed on the platform, and a first upper die is detachably installed in the punching portion. The base portion is disposed between the punching portion and the platform, and a first lower die is detachably installed in the base portion. The punching portion is adapted to move back and forth along a first direction relative to the platform. The turret device is adapted to move along a second direction relative to the platform, and the first direction is perpendicular to the second direction. A plurality of second upper dies and second lower dies are correspondingly installed on the turret device.

First claim

What is claimed is:

1. A punching system, adapted to punch a sheet metal, the punching system comprising:
a platform;
a punching portion, disposed on the platform, and a first upper die being detachably installed in the punching portion;
a base portion, disposed between the punching portion and the platform, and a first lower die being detachably installed in the base portion, wherein the first upper die installed in the punching portion is adapted to move back and forth along a first direction relative to the base portion; and
a turret device, adapted to move along a second direction relative to the platform, wherein the second direction is orthogonal to the first direction, and a plurality of second upper dies and a plurality of second lower dies are respectively and correspondingly installed on the turret device, the turret device is adapted to rotate about an axial direction parallel to the first direction, so as to transfer one of the second upper dies and one of the second lower dies to a pending position of the turret device respectively corresponding to the punching portion and the base portion, and the turret device is adapted to move along the second direction towards the punching portion and the base portion, so as to cause the turret device to respectively replace the first upper die and the first lower die with one of the second upper dies and one of the second lower dies.

2. The punching system as claimed in claim 1 , further comprising:
a first slide rail, disposed between the turret device and the platform and along the second direction, wherein the turret device is adapted to slide, via the first slide rail, relative to the platform.

3. The punching system as claimed in claim 1 , further comprising:
a carriage, disposed on the platform, and configured to carry the sheet metal, wherein the carriage is adapted to move along the second direction relative to the platform, the punching portion and the base portion.

4. The punching system as claimed in claim 3 , further comprising:
a clamping portion, movably disposed on the carriage, and adapted to clamp the sheet metal to detachably fix the sheet metal on the carriage, wherein the clamping portion is adapted to move along a third direction relative to the carriage, and the third direction is orthogonal to the first direction and the second direction.

5. The punching system as claimed in claim 3 , further comprising:
a slide rail, disposed between the platform and the carriage and along the second direction, wherein the carriage slides along the slide rail in the second direction relative to the platform.

6. The punching system as claimed in claim 1 , wherein the turret device comprises an upper turret portion and a lower turret portion, and the second upper dies and the second lower dies are respectively detachably installed on the upper turret portion and the lower turret portion.

7. The punching system as claimed in claim 1 , wherein the turret device comprises a plurality of carrying arms, and the carrying arms each have a respective holding portion, and the second upper dies and the second lower dies are each detachably fixed to a respective one of the holding portions.

8. The punching system as claimed in claim 7 ,
wherein at least two of the carrying arms do not carry any of the second upper dies and the second lower dies, and
the at least two of the carrying arms are adapted to rotate about the axial direction to the pending position, so as to unload the first upper die and the first lower die from the punching portion and the base portion to the respective holding portion of the at least two carrying arms.

9. The punching system as claimed in claim 1 , wherein the punching portion further comprises a first driving member and a second driving member, wherein the first driving member is adapted to drive the first upper die to move up and down along the first direction relative to the base portion, and the second driving member is adapted to drive the first upper die to pivotally rotate about the first direction.

10. The punching system as claimed in claim 1 , wherein the base portion further comprises a driving member adapted to drive the first lower die to pivotally rotate about the first direction.
