Apparatus for working leads of electrical components
| Details |
Inventors: Weresch, Thomas;
Assignee:
Primary Examiner: Larson; Lowell A.
Assistant Examiner:
Attorney, Agent or Firm: Antonelli, Terry & Wands
An apparatus for working on the leads of electrical components has a component inlet or supply unit taking the form, for example, of a chute with a guideway opening, or with an inlet for the supply of components fixed to belts or paper tapes. The apparatus furthermore has two tools, each placed on a tool support. The two tools are moved together for forming the component leads, the leads being placed in the path of the tools. The tools are supported on a carriage, which may be moved in a direction parallel to the direction of input of the components. Furthermore, the tools are moved together in timed relation to input of the components and the working motion of the carriage. In the case of such an apparatus, for making a better design of the working steps and events taking place on operation as the apparatus is moved, and for making adjustment more readily possible, each tool support has a guide face parallel to the direction of working motion, the length of each guide face being at least equal to the length of the working motion, driving levers, which are turningly supported on a base-plate, resting against the guide faces. The driving levers are worked by at least one tool shutting cam powered by a driving motor. Such an apparatus may be used for general processing of component leads and, more specially cutting to length, bending or kinking such leads on transistors, capacitors etc. |

DETAILED DESCRIPTION I claim: 1.
In an apparatus for working leads of electrical components having an inlet unit with a guideway and fixedly supported on a base-plate, two tools designed for operation with said inlet unit and powered by a driving motor, the tools each being positioned on a different one of two tool supports so that they may be moved towards each other for bending and kinking the leads of the said components between them, the leads running into the working path of the tools, which are supported on a carriage designed for a backward and forward working motion, parallel to the inlet unit's guideway and which are able to be moved towards each other for shutting in a direction normal to the inlet direction of the components and in timed relation to the working motion of said carriage, the invention residing in that each tool support has a guide face generally parallel to said working motion of said carriage, the length of the guide faces being at least equal to the size of the working motion, the apparatus further having two levers, turningly supported on said base-plate, each one of these levers running against a different one of said guide faces, and at least one shutting cam designed to be turned by said motor for moving said levers.
2.
An apparatus as claimed in claim 1, further having a working cam for driving said carriage and causing the working motion thereof.
3.
An apparatus as claimed in claim 2, wherein said working cam has a cam face with a part of greater diameter and a part of lesser diameter, the two cam face parts being joined together by a cam face part of changing diameter.
4.
An apparatus as claimed in anyone of claims 1 to 3, wherein the guide faces are turned facing away from the inlet unit and wherein the tool supports are springingly forced away from each other against the levers.
5.
An apparatus as claimed in anyone of claims 1 to 3, further having, for each tool support, a guide normal to the working motion.
6.
An apparatus as claimed in anyone of claims 1 to 3, having one such single, common tool shutting cam for driving the levers, the cam having a two-ordered symmetry about a diametral plane, two such parts of the working motion for each single turn of the shutting cam taking place
