Multi-wire hand in hand automatic terminal press
Technical field
The present invention relates to wire rod class assembling manufacture field, especially a kind of multi-wire hand in hand automatic terminal press.
Background technology
Wire harness is wire rod or electric wire, and TV, mobile phone, camera, automobile, air-conditioning, broadcast receiver, aircraft, train etc. all be unable to do without wire harness.Due to the difference of project organization, wire loop is by wire pair electric wire, and wire pair wiring board forms.Automatic terminal press can be by wire harness cut-to-length, fixed length peeling, and then stamp terminal.Be in wiring harness and automotive wire bundle processing industry of automatic terminal press is widely used, and existing technique is: 1. single line inlet wire (length is adjustable); 2 cut out line peeling (peeling length can not be adjusted at random, by severing die adjustment); 3. single head is being pressed terminal; 4 other end peelings; Terminal is being pressed in 5 other ends.Flow process is roughly: single line bundle is sent into, and clamp chuck clamps wire harness, and then peeling cutter carries out severing peeling action, then by terminal press, carries out terminal and is pressing moulding; The power source of whole flow process is stepper motor and cylinder.Owing to can only operate by single wire harness at every turn, speed is slower, cannot meet in enormous quantities and large-scale production and processing requirement, average process velocity is below 5000/hour, skilled artificial average speed be 3500-7000 bar/hour, real economy benefit is undesirable, single head incoming type automatic terminal machine improves speed mainly by accelerating cylinder and motor speed, the faster failure rate of speed is higher, the automatic terminal press of fully mechanical transmission is higher to processing request, and assembling and debugging are all more difficult.
