Abstract
Abstract Apparatus for mechanically processing (cutting to length, crimping and/or bending) the connecting wires of electrical components and being of a generally similar nature to that of U.S. Pat. No. 3,900,053. The present invention, however, provides for the various toothed wheels, which are mounted on a rotatable main shaft, to be readily removable for the purpose of exchanging them for others in order to adapt the apparatus to the processing of different components. To this end, the toothed wheels are mounted on sleeves on the main shaft and the latter has a bearing arrangement at one end which includes a detachable bearing plate mounted in a aperture in the apparatus housing, which allows the toothed wheels to be drawn off the main shaft over that end and through the aperture when the bearing plate is detached and the toothed wheels unclamped from the main shaft. Also, the cutting, crimping and bending tools, which cooperate with respective ones of the toothed wheels (namely, transporting, crimping and bending wheels) are supported directly on the apparatus housing and are positionally adjustable independently of the toothed wheels. Various other features are described, including an improved form and arrangement of counter-holders for control of processing forces and providing ramps for the ejection of the connecting wires from the toothed wheels when they have passed the tools, and the provision of both main and auxiliary cross-members, the latter for supporting additional tools, possibly including impact tools.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
195 words
Apparatus for mechanically processing the connecting wires of electrical components, the apparatus comprising toothed wheels the spaces between whose teeth receive the connecting wires which are to be processed, all of which wheels are arranged coaxially, are adapted to be driven in rotational movement by a common main shaft mounted in a housing and are adapted to be adjusted in the axial direction of the main shaft and clamped in position, the apparatus further comprising mechanical processing tools which are arranged secured to the housing and to be capable of being adjusted in the direction of the main shaft and clamped in position, and to co-operate appropriately for the processing operation in each case with respective ones of the toothed wheels, wherein the main shaft has a bearing arrangement including at least one removal end of said shaft, whereby the main shaft is releasable so that the toothed wheels can be removed from the main shaft over the removal end when their clamping to said shaft is released, and wherein the processing tools are supported directly on the housing and are adjustable independently of the toothed wheels in the axial direction of the main shaft.
Claim 2
Dependent Claim
195 words
Apparatus for mechanically processing the connecting wires of electrical components, the apparatus comprising toothed wheels the spaces between whose teeth receive the connecting wires which are to be processed, all of which wheels are arranged coaxially, are adapted to be driven in rotational movement by a common main shaft mounted in a housing and are adapted to be adjusted in the axial direction of the main shaft and clamped in position, the apparatus further comprising mechanical processing tools which are arranged secured to the housing and to be capable of being adjusted in the direction of the main shaft and clamped in position, and to co-operate appropriately for the processing operation in each case with respective ones of the toothed wheels, wherein the main shaft has a bearing arrangement including at least one removal end of said shaft, whereby the main shaft is releasable so that the toothed wheels can be removed from the main shaft over the removal end when their clamping to said shaft is released, and wherein the processing tools are supported directly on the housing and are adjustable independently of the toothed wheels in the axial direction of the main shaft.
Claim 3
Dependent Claim
37 words
Apparatus according to claim 1, wherein the axis of the main shaft extends through a housing aperture, the removal end is mounted in a detachable bearing plate, and the toothed wheels are removable through said housing aperture.
Claim 4
Dependent Claim
15 words
Apparatus according to claim 2, wherein the bearing plate is centered in the housing aperture.
Claim 5
Dependent Claim
34 words
Apparatus according to claim 1, wherein the toothed wheels are supported on sleeves surrounding the main shaft, on a bearing diameter which corresponds substantially to the root circle diameter of the corresponding tooth system.
Claim 6
Dependent Claim
63 words
Apparatus according to claim 1, wherein the tools are guided to be capable of displacement on a main cross-member parallel to the main shaft and are adapted to be clamped in position, and the main cross-member is adapted to be clamped fast on the housing and, when the clamping arrangement is released, to be displaced perpendicularly to the main shaft against adjustable abutments.
Claim 7
Dependent Claim
31 words
Apparatus according to claim 1, including an auxiliary cross-member for supporting additional tools, the auxiliary cross-member being arranged above the main shaft, offset by about 90° relatively to the main cross-member.
Claim 8
Dependent Claim
92 words
Apparatus according to claim 1, including at least one counter-holder associated with the toothed wheels, the counter-holder being mounted on an auxiliary shaft secured to the housing and parallel to the main shaft, being under spring action directed towards the tools and being provided with a tension relief nose and/or an ejector, the counter-holder comprising a cranked portion at its end remote from the main shaft and being mounted with the cranked portion on the auxiliary shaft, the spring acting on the counter-holder having a projection which elastically locks the cranked portion.
Claim 9
Dependent Claim
50 words
Apparatus according to claim 1, wherein said tools include a pair of crimping tools, one of which is disposed before the other in the direction of rotation of said wheels, the forward crimping tool in said direction of rotation being associated with an auxiliary counter-holder which has a crimp guide.
Claim 10
Dependent Claim
52 words
Apparatus according to claim 8, wherein said toothed wheels comprised a transporting wheel and a crimping wheel, the auxiliary counter-holder being arranged between the transporting wheel and the crimping wheel and being guided in a peripheral groove of a spacer disc which is arranged between the transporting wheel and the crimping wheel.
Claim 11
Dependent Claim
40 words
Apparatus according to claim 8, wherein the crimp guide comprises a ramp which is formed on the auxiliary counter-holder between the crimping tools in the direction of rotation of said wheels and rises radially outwardly in said direction of rotation.
