Definitions
- the invention relates to a crimping tool for crimping crimp contacts, in particular crimp contacts in tape form, with a base body comprising a pressing device and a table assigned to the base body for guiding the crimp contacts, the crimp contacts being fed to the pressing device via the table.
- Crimping tools of the type in question have long been known in practice and exist in a wide variety of embodiments.
- the known crimping tools are designed for the efficient processing of crimp contacts in tape form, in longitudinal or transverse transport or for sortable individual contacts.
- the known crimping tools are often designed as quick-change tools and can be used on individual workstations or fully automatic machines and transfer lines.
- the processing of electrical conductors with a cross-sectional area of approximately 0.08 mm 2 to 50 mm 2 is possible.
- the crimp contacts of the pressing device are fed exactly to the position of the crimping die.
- the table In a known crimping tool, the table is guided in two grooves formed in the base body. The table is fixed relative to the base body by means of clamping screws. To change the position of the table, the Clamping screws are loosened first, then the position of the table is adjusted and finally the clamping screws are tightened again.
- Positioning the table in this way is complex on the one hand due to the three last-mentioned working steps and, on the other hand, tilting of the table in the groove-like guides is often unavoidable. This increases the wear of the crimping tool considerably.
- the present invention is therefore based on the object of specifying a crimping tool of the type mentioned in the introduction, in which a precise and variable positioning of the crimp contacts is achieved with simple means.
- the above object is achieved on the one hand by the features of patent claim 1.
- the crimping tool in question is designed such that an adjusting mechanism is provided for the stepless positioning of the table along the guide.
- the above object is achieved in a surprisingly simple manner by an adjusting mechanism for the stepless positioning of the table along the guide.
- the number of work steps for changing the position of the table is reduced.
- the desired positioning can only be achieved by actuating the adjusting mechanism. Tilting of the table in the guide is avoided due to the stepless positioning.
- the variability of the positioning is increased.
- the disadvantages of the known positioning process in which mostly only a gradual table positioning was possible in practice due to the impractical handling, are avoided with the stepless positioning according to the crimping tool according to the invention. Consequently, the crimping tool according to the invention realizes a crimping tool in which a precise and variable positioning of the crimp contacts is achieved with simple means.
- the adjusting mechanism could comprise an elastic means acting between the table and the base body in the direction of the guide.
- the elastic means could continue to press the table against a stop assigned to the base body. The position of the stop could then in turn be changeable relative to the base body in the guide direction, so that the table can only be positioned by changing the position of the stop. This would result in a particularly simple positioning.
- the elastic means could be a coil spring in a structurally simple manner. However, leaf springs or the like could also be used here.
- the elastic means could run around the stop.
- the stop could then be arranged within the screw turns of the spring.
- the stop is a screw, preferably an Allen screw, which is passed through the table and screwed into a thread in the base body.
- the position of the table could be adjusted relative to the base body simply by screwing the screw in or out.
- the position of the table relative to the base body would then be secured by the elastic means being pressurized.
- the elastic means could also be arranged in a recess in the table. This would enable a particularly safe and precise pressurization.
- the screw could be self-locking. The introduction of a plastic material into the thread in the base body would be conceivable. Alternatively or in addition to this, the screw could be secured against unintentional unscrewing by applying pressure. This pressurization could also be caused by the elastic means.
- a further possibility for securing the position of the screw in the thread could take place by means of a bolt screwed through the base body towards the screw.
- the thread for the bolt would almost extend into the thread of the screw.
- the bolt could be a grub screw.
- the stop could also be assigned to the table, the screw then being screwed through the base body into the table. The securing of the screw against unintentional unscrewing could then take place analogously to the above.
- the guidance could comprise at least one and preferably two pins or pins assigned to the base body and / or the table.
- the pins could then run in receptacles formed in the table or in the base body. Such recordings could be easily realized through holes.
- pins with a dovetail profile or a square profile could also be provided. In the case of the latter profile shapes in particular, the formation of a pin would be sufficient for a secure hold.
- a feed unit for the crimp contacts could be assigned to the base body.
- the feed unit could include a push element and a feed finger that can be moved back and forth in the feed direction of the crimp contacts, the feed finger being operatively connected to the push element via a coupling element.
- the crimping tool could be designed in such a way that the distance of the feed finger to the table remains constant during and after the actuation of the adjusting mechanism.
- the coupling element could be guided in the feed finger in such a way that the distance between the coupling element and the feed finger changes to the same extent as the distance between the table and the base body during the actuation of the adjusting mechanism. It would be beneficial to guide the feed finger below the table in a groove made of two guide strips extending in the feed direction.
- the guide rails could either be integrated integrally into the table or screwed to the table from below.
- a crimping tool for crimping crimp contacts in particular crimp contacts in tape form, with a base body comprising a pressing device and a table assigned to the base body for guiding the crimp contacts, the crimp contacts being fed to the pressing device over the table, is designed in such a way that the table is a Positioning device for functional positioning of the crimp contacts relative to the table includes.
- the guide element could be movable perpendicular to the feed direction. With regard to a long guide path and thus a particularly secure positioning, the guide element could extend in the feed direction.
- the guide element could also be strip-shaped and arranged perpendicular to the table surface. With such a strip-like design, the guide element could engage particularly securely between at least two contact elements of the crimp contacts to be bent during operation of the crimping tool.
- the strip-shaped guide element arranged perpendicular to the table surface is arranged between contact elements of the crimp contacts guided on the table, which protrude perpendicularly from the table.
- the guide element could be aligned along a crimp contact strip.
- the distance of the guide element relative to the table could be changeable. It must be ensured that the crimp contacts or the crimp contact strip can slide securely between the guide element and the table, without any significant movement of the crimp contacts perpendicular to the feed direction being possible.
- the guide element could be attached to the table by means of a holding device.
- the holding device could include at least one rod, at one end of which the guide element is fixed.
- the guide element could be fixed on the rod by clamping the guide element by means of a screw which is guided through the guide element and screwed into the rod in the direction of the rod axis. In the assembled state, the rod could then be arranged perpendicular to the feed direction and in a plane running parallel to the table plane.
- a crimping tool would also be conceivable, in which, on the one hand, an adjusting mechanism is provided for the stepless positioning of the table along a guide and, on the other hand, a table with a positioning device for correctly positioning the crimp contacts relative to the table.
- an adjusting mechanism is provided for the stepless positioning of the table along a guide and, on the other hand, a table with a positioning device for correctly positioning the crimp contacts relative to the table.
