Abstract

A machining apparatus includes a movement direction converting mechanism that converts lowering movement of a first punch into raising movement of a second punch and converts lowering movement of the second punch into raising movement of the first punch. The first punch and the second punch are raised and lowered in an alternating manner by this movement direction converting mechanism. Accordingly, machining by the first punch and machining by the second punch are performed individually.

First claim

What is claimed is:

1. A machining apparatus that includes a first punch and a second punch driven individually, wherein the machining apparatus lowers the second punch when the first punch is raised, and the machining apparatus raises the second punch when the first punch is lowered, the machining apparatus comprising:
a first cam adapted to raise the first punch;
a second cam adapted to raise the second punch;
a rotating shaft provided with the first cam and the second cam;
a rotational driver that causes the rotating shaft to rotate; and
a movement direction converting mechanism that converts lowering movement of the first punch into raising movement of the second punch and converts lowering movement of the second punch into raising movement of the first punch, wherein
the first punch and the second punch are raised and lowered in an alternating manner, and machining by the first punch and machining by the second punch are performed individually,
the movement direction converting mechanism includes:
a first arm member that is caused to pivot about one end thereof by the first cam;
a first raising/lowering member that is raised and lowered according to the pivoting of the first arm member;
a second arm member that is caused to pivot about one end thereof by the second cam;
a second raising/lowering member that is raised and lowered according to the pivoting of the second arm member; and
a link member that has one end supported by the first raising/lowering member and another end supported by the second raising/lowering member, and the link member pivots about a central portion arranged between the first raising/lowering member and the second raising/lowering member.

2. The machining apparatus according to claim 1 , comprising:
an elastic member that is arranged at a position facing the one end of the link member and is pressed by the one end of the link member and compressed.

3. The machining apparatus according to claim 1 , wherein
the first punch and the second punch perform different machining from each other.

4. The machining apparatus according to claim 1 , wherein
the movement direction converting mechanism includes a first rack adapted to raise and lower the first punch, a second rack adapted to raise and lower the second punch, and one pinion that engages with both the first rack and the second rack.

5. The machining apparatus according to claim 4 , wherein
the first punch and the second punch perform machining to remove an insulation coating from conductors by different amounts.

6. The machining apparatus according to claim 4 , comprising:
a first die that applies machining together with the first punch and a second die that applies machining together with the second punch, wherein
the first die and the second die is individually displaceable in a direction to be closer to or farther from the respective first punch and second punch.

7. The machining apparatus according to claim 6 , wherein
the first die is lowered when the second die is raised, and the first die is raised when the second die is lowered.
