Definitions
- the invention relates to a method for producing and / or processing Parts in progressive tools and especially contact elements such as Contact pins, contact springs and the like for electronic connectors with the Features of the preamble of claim 1.
- contact springs for electrical connectors it is common to use them during the manufacturing process, So while punching, embossing and bending in the desired shape can be brought during the subsequent galvanic Coating and also during the transport to customers, manufacturers etc. in mostly one-piece connection with a transport strip to leave, with a separation or separation of the parts from the transport strip usually done later at the customer. Find transportation strips but also in the case of so-called free-falling parts during their manufacture, which are isolated before delivery to the customer and from the transport strip be separated.
- the division of the transport strip is the distance between the Central axes of adjacent parts to be machined, not directly standardized, however Transport strips are usually only used with very specific divisions, so that these can be handled easily by the customer.
- usual Divisions are, for example, 2.54 mm and multiples thereof.
- In addition to the Division is also to be considered that two adjacent parts for manufacturing reasons a certain minimum distance (e.g. half to one and a half times the sheet thickness). This minimum distance affects on the other hand also the manufacturing costs: Because a bigger one Clearly, distance also means more material after punching out the parts must be thrown away as waste.
- the present invention is based on the object, the method for Manufacturing and / or machining parts in progressive dies with regard to To make use of materials and galvanization costs more economical.
- This object is achieved in that the transport strip by reshaping at least in the area between the definition positions two adjacent parts on the transport strip reduced in material thickness becomes so that the distance between two adjacent parts increases.
- Such a shaping enables the material thickness of the transport strip to be reduced significantly reduce and accordingly the distance between the Determining positions of neighboring parts clearly (in example cases by approx. twenty percent). This gives you a correspondingly clear one Saving what the material costs due to the reduced operating weight of the stamping material and as far as the electroplating costs are concerned, which are taken into account the length of the transport strip.
- Reshaping does not simply increase the distance between parts, but that it does so the division of the transport strip is increased to a fixed dimension meets the requirements of the customer for the parts including the transport strip to be able to process further.
- This division after forming is expediently e.g. 2.54 mm or a multiple thereof.
- the forming of the transport strip in particular also with regard to the Reduction of the electroplating costs is carried out, it is recommended to reshape immediately or indirectly after the galvanic process step To carry out coating. It is also possible that the forming only at the end of the manufacturing and / or processing process delivery to the customer.
- the present invention extends not only to the manufacturing process and / or machining of parts in progressive dies, but also on the process product, namely a transport strip with parts for electrical connectors and the like for common handling several parts during their manufacturing and / or processing process
- the transport strip consists of a metal belt on which the parts in Range of fixing positions in particular through one-piece molding and / or are determined by adding and from which the parts protrude laterally.
- the transport strip is at least formed by reshaping Area between the definition positions reduced in material thickness and thereby the length distance between the fixing positions of neighboring ones Parts enlarged, which can achieve the above advantages.
- the others above in relation to the manufacturing and / or processing method Advantages described form the inventive Transport strips themselves as well. Accordingly, other are advantageous Embodiments of the transport strip in subclaims 9 to 11 played.
- the idea of the invention can also be used to save material exploit if the tape material from which the transport strip and if necessary the molded parts are made, at least in the as Transport strip acting area sections with reduced material thickness having.
- These sections which are expediently in the transverse direction of the Tape extend over the entire width of the transport strip and also can be produced by forming such as stamping, rolling and the like, reduce the volume and operating weight of the strip material in one for the End product unimportant area.
- This "unimportant" area is of course special the area of the transport strip, but theoretically also the one Width range of the strip material made with reduced material thickness from which the parts are later punched out, but only this in the sections that lie outside the parts and that when punching out the parts form waste material.
- the transport strip 1 shown in Figure 1 has a material thickness D and a width B and has pilot holes 2, 3 as centering aids when handling of the transport lane.
- the transport strip carries 1 laterally molded parts 4, 5 for an electrical connector, the are integrally connected to the transport strip.
- Two adjacent connector parts 4, 5 have a mutual distance a, which is for manufacturing reasons should not fall below a certain minimum, for example to leave enough space for a punching tool or for processing not to impede the adjacent plug part.
- the central axes of neighboring Plug parts 4, 5 have a distance T, which is called the pitch becomes.
- the material thickness of the transport strip usually depends on the material thickness the mostly one-piece molded connector parts is determined, but for pure tensile loads that become effective during the manufacturing and machining process is oversized, it affects the function of the transport strip not if this is in its entire width in parts or even over its entire length is reduced to a lower material thickness.
- the advantage of the present invention is that the manufacturing and / or processing method for connector parts cheaper can be designed without sacrificing quality, as the material thickness the transport strip has no effect on the end product, as long as the division required by the customer is observed.
