Abstract
Abstract An automatic crimping apparatus is provided for applying electrical terminals on the end of a wire inserted in a crimp station comprising a crimp anvil mounted on a base, a crimp arm for mounting crimp tooling operatively connected to the base through a toggle linkage, a feed mechanism for supplying terminals to the crimping station in the form of a continuous strip, and a pneumatic control system wherein a four-way airpilot valve and first and second pressure-relief valves are used to sequence the drive mechanism for the crimp arm and feed mechanism.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
90 words
An apparatus for applying terminals to the ends of wires comprising, a base having a crimping station for receiving a terminal and a wire, crimp means connected to said base and a tool mounting block disposed thereon, first drive means connected to said crimp arm for crimping said terminal on said wire, feed means for supplying terminals to said crimping station, second drive means connected to said feed means, and control means for sequentially activating said first and second drive means and simultaneously deactivating said first and second drive means.
Claim 2
Independent Claim
90 words
An apparatus for applying terminals to the ends of wires comprising, a base having a crimping station for receiving a terminal and a wire, crimp means connected to said base and a tool mounting block disposed thereon, first drive means connected to said crimp arm for crimping said terminal on said wire, feed means for supplying terminals to said crimping station, second drive means connected to said feed means, and control means for sequentially activating said first and second drive means and simultaneously deactivating said first and second drive means.
Claim 3
Dependent Claim
39 words
An apparatus, as recited in claim 1, wherein said first drive means additionally comprIses a toggle linkage and at least one of the toggle links is connected to an eccentric shaft for adjusting the stroke of the crimp arm.
Claim 4
Dependent Claim
67 words
An apparatus, as recited in claim 1, wherein said control means comprises a four-way air pilot valve and a pair of pressure relief valves, and said pressure relief valves are connected in series to an outlet port of said four-way air pilot valve and a relief port of one of said pressure relief valves is connected to an air pilot port of said four-way air pilot valve.
Claim 5
Dependent Claim
43 words
An apparatus, as recited in claim 1, wherein said feed means comprises a member having an actuator pin, and said second drive means comprises a drive member having a slot disposed therein for delaying engagement of said actuator pin by said drive means.
Claim 6
Independent Claim
186 words
An apparatus for applying terminals on the ends of wires comprising, a base having lower crimp tooling mounted thereon at a crimping station for receiving a terminal and an end of a wire, a crimp arm having one end pivotally connected to said base and a tool block for mounting upper crimp tooling on the other end of said crimp arm, a toggle linkage having a first link connected to said tool block on one end of said crimp arm and a second link connected to said base, first pneumatic drive means connected to said toggle linkage for engaging said upper crimp tooling mounted on said crim arm with said lower tooling on said base and crimping the terminal on the end of the wire at said crimping station, a feed track for supplying said terminals to said crimping station, means for feeding said terminals along said feed track to said crimping station, second pneumatic drive means for engaging said means for feeding terminals, and pneumatic control means for sequentially activating the first and second drive means and simultaneously deactivating said first and second drive means.
Claim 7
Independent Claim
186 words
An apparatus for applying terminals on the ends of wires comprising, a base having lower crimp tooling mounted thereon at a crimping station for receiving a terminal and an end of a wire, a crimp arm having one end pivotally connected to said base and a tool block for mounting upper crimp tooling on the other end of said crimp arm, a toggle linkage having a first link connected to said tool block on one end of said crimp arm and a second link connected to said base, first pneumatic drive means connected to said toggle linkage for engaging said upper crimp tooling mounted on said crim arm with said lower tooling on said base and crimping the terminal on the end of the wire at said crimping station, a feed track for supplying said terminals to said crimping station, means for feeding said terminals along said feed track to said crimping station, second pneumatic drive means for engaging said means for feeding terminals, and pneumatic control means for sequentially activating the first and second drive means and simultaneously deactivating said first and second drive means.
Claim 8
Dependent Claim
31 words
An apparatus, as described in claim 5, wherein said toggle linkage is connected to said base through an eccentric shaft for adjusting the engagement of the upper and lower crimp tooling.
Claim 9
Dependent Claim
61 words
An apparatus, as recited in claim 5, wherein said control means comprises first and second pressure relief valves and the input port of said first relief valve is connected to said first drive means and the relief port of said first relief valve is connected to the input port of said second pressure relief valve and to said second drive means.
Claim 10
Dependent Claim
38 words
An apparatus, as recited in claim 7, wherein said control means additionally comprises a four-way air pilot valve and the relief port of said second relief valve is connected to an air pilot port of said pilot valve.
Claim 11
Dependent Claim
69 words
An apparatus, as recited in claim 5, wherein said means for feeding said terminals comprises a feed arm pivotally mounted on said feed track having a feed finger mounted on one end and a spring connected from said base to said feed arm over the center of the pivot point of said feed arm, and the other end of the feed arm is connected to said second drive means.
Claim 12
Dependent Claim
32 words
An apparatus, as recited in claim 9, wherein said second drive means comprises a drive member having a slot disposed therein for delaying engagement of said actuator pin on said feed arm.
