Riveting apparatus
View Patent ↗A riveting apparatus has a support die with a support surface. The support surface supports a rivet that extends through a circuit board and an electrical connector. The support surface has a first inclined surface, a second inclined surface, and a depression positioned therebetween. The depression receives a head of the rivet and positionally aligns the rivet with an upper tool unit as the rivet is guided across the first inclined surface toward the second inclined surface. The upper tool unit fastens the rivet to the circuit board.
1. A riveting apparatus, comprising:
a support die having a support surface that supports a rivet that extends through a circuit board and an electrical connector, the support surface having a first inclined surface, a second inclined surface, and a depression positioned therebetween, the depression receives a head of the rivet and positionally aligns the rivet with an upper tool unit that fastens the rivet to the circuit board as the rivet is guided across the first inclined surface toward the second inclined surface, and the support die includes a main block and a sub-block, the main block includes the second inclined surface and a base that supports the sub-block, the sub-block includes the first inclined surface and the depression.
2. The riveting apparatus of claim 1 , wherein the support surface has a substantially flat portion adjacent to the depression.
3. The riveting apparatus of claim 1 , wherein the first and second inclined surfaces have a length substantially the same as the electrical connector.
4. The riveting apparatus of claim 1 , wherein the second inclined surface is formed so that the circuit board absorbs a force of the upper tool unit caused by fastening the rivet to the circuit board.
5. The riveting apparatus of claim 1 , wherein the support die causes a sensation of correct positioning to be transmitted to an operator when the head of the rivet is received in the depression.
6. The riveting apparatus of claim 1 , wherein the first and second inclined surfaces converge to form a peak and the depression is formed at the peak.
7. The riveting apparatus of claim 1 , wherein the support die has a cut-out that receives a column having a substantially U-shaped recess that forms the depression.
8. A riveting apparatus, comprising:
a support die having a support surface that supports a rivet that extends through a circuit board and an electrical connector, the support surface having a first inclined surface, a second inclined surface, and a depression positioned therebetween, the depression receives a head of the rivet and positionally aligns the rivet with an upper tool unit that fastens the rivet to the circuit board as the rivet is guided across the first inclined surface toward the second inclined surface, and the support die has a cut-out that receives a column having a substantially U-shaped recess that forms the depression.
9. The riveting apparatus of claim 8 , wherein the support surface has a substantially flat portion adjacent to the depression.
10. The riveting apparatus of claim 8 , wherein the first and second inclined surfaces have a length substantially the same as the electrical connector.
11. The riveting apparatus of claim 8 , wherein the second inclined surface is formed so that the circuit board absorbs a force of the upper tool unit caused by fastening the rivet to the circuit board.
12. The riveting apparatus of claim 8 , wherein the support die causes a sensation of correct positioning to be transmitted to an operator when the head of the rivet is received in the depression.
13. The riveting apparatus of claim 8 , wherein the first and second inclined surfaces converge to form a peak and the depression is formed at the peak.
