Crimping press
Crimping presses that include a frame with a first crimping tool, and a press carriage with a second crimping tool. A bias applicator applies prebiasing initial force acting at least codirectionally to crimping force reaction that is separatory to the first and second crimping tools. The prebiasing initial force acts prior to crimping engagement of the crimping tools. The bias applicator is situated between holders.
1. A crimping press comprising:
a machine frame;
a drive shaft, said drive shaft being mounted in a drive shaft bearing;
a cam connected to said drive shaft;
a connecting rod operatively connected to said cam, said connecting rod being operatively connected to said cam at a first location on said connecting rod;
a press carriage, said connecting rod being operatively connected to said press carriage via a connecting rod bearing, said connecting rod being operatively connected to said press carriage at a second location on said connecting rod;
at least one carriage guide connected to said machine frame, said press carriage being mounted on said at least one carriage guide;
a first crimping tool mounted on said machine frame;
a flexural beam connected to said press carriage;
a second crimping tool connected to said press carriage via said flexural beam;
a first bias applicator holder connected to said press carriage;
a second bias applicator holder connected to said machine frame; and
a bias applicator configured to apply a prebiasing initial force acting at least codirectionally to the crimping force reaction separatory to said first and second crimping tools prior to crimping engagement of said first and second crimping tools, said bias applicator being situated between said first and second bias applicator holders.
2. A crimping press as claimed in claim 1 further comprising:
said bias applicator includes a spring; and
said spring is tensioned to pull said first bias applicator holder towards said second bias applicator holder.
3. A crimping press as claimed in claim 1 further comprising:
said bias applicator includes a first spring; and
said first spring is compressed to push said first bias applicator holder away from said second bias applicator holder.
4. A crimping press as claimed in claim 3 further comprising:
a third bias applicator holder connected to said machine frame; and
a second spring between said first and third bias applicator holders, said second spring being tensioned to pull said first bias applicator holder towards said third bias applicator holder.
5. A crimping press as claimed in claim 1 further comprising:
a spring;
a spring adjuster for adjusting the prebiasing initial force of said spring; and
said bias applicator includes said spring.
6. A crimping press as claimed in claim 1 further comprising:
said bias applicator includes an actuator,
said actuator is situated to pull said first bias applicator holder towards said second bias applicator holder.
7. A crimping press as claimed in claim 1 further comprising:
said bias applicator includes a first actuator,
said first actuator is situated to push said first bias applicator holder away from said second bias applicator holder.
8. A crimping press as claimed in claim 7 further comprising:
a third bias applicator holder connected to said machine frame; and
a second actuator between said first and third bias applicator holders, said second actuator situated to pull said first bias applicator holder towards said third bias applicator holder.
9. A crimping press as claimed in claim 1 further comprising:
said bias applicator includes a spring, and said bias applicator includes an actuator.
