Punches - Import export

KLN develops and manufactures punching machines with precise curve design at the surface, for example to punch holes for the distance sensor holders or lamps in lacquered bumpers. Realisation of high-precision round or angled holes, but protection of the part; also suitable for already lacquered surfaces.

Our special ability lies in the processing of metal strips pre-coated with adhesives. With this material it is particularly important not to damage the surface mechanically whilst at the same time not to impair the ability to bond. This skill enables us to supply stamped parts for bonding with rubber and/or thermoplastics, such as Vibration damping elements spring elements stabilizers functional parts components We guarantee a functional workability of the product for 6 months after delivery.

The tool top (stamp) has an internal form, whose bottom part (matrix) has the corresponding opening (see image). These punch units are used in the areas of sheet shaping. Contact I have read and agree to the privacy policy. *Pflichtfelder

Keyway broaching on lathes is a common thing. What is new is to speed up this operation with low stress for the machine! Slot is driven by the tool turret of the machine, with the input rotary motion being converted to a translation with superimposed lift-off function. This makes programming extremely easy. The keyway broaching unit is positioned in the prepared bore – in such a way as to make the extended tappet oriented to the end position in the Z axis. The depth of the slot is produced by a constant X-feed moving between 0.04-0.08 mm/stroke. The speed of the spindle ranges between 400 R/min – 1,000 R/min, with one rotation corresponding to a complete stroke. This way, for instance, a feather key groove with a width of 6 mm and a depth of 5 mm is produced within 7.5 sec. (800 R/min and 0.05 mm feed/rotation). With this operation it is important that the chip can break at the end of the groove, that is that a cut-in or a bore exists.

Punching units Punching unit with exchangeable cutting elements for sheets and profiles up to a material thickness of 25.0 mm and a hole diameter of 150.0 mm JOKA punching units consist of a special cast stand that accepts the punch and die and ensures the exact axis alignment between the cutting elements (punch and die). In addition, there is a stripping system in the upper part of the tool stand, as the material wipes off automatically after punching. The scraper contains two or more disc spring packages that guarantee perfect scraping even in the border areas. A fixed connection between the tool and the upper part of the press is therefore not required. To determine the exact position, each tool has a positioning pin (two for shaped holes) on the underside, which is precisely aligned with the cutting elements (center of the hole). The above picture shows a complete punching unit without cutting elements and one cutting set (punch and die) each for round hole or shaped hole.

Our specialty is “punching”. We have many years of experience in this area. We also solve your problems with our own tool and system construction.

For the automation of your production, we develop and build semi or fully automatic hydraulic punching systems, tailored to your special wishes and needs.

Since the development of coil springs in turret tooling, engineers have been challenged to increase the productivity of turret presses even further. In a traditional press, the option of material type and material thickness is limited by the coil springs inability to produce a high force in a short linear distance. When this performance is necessary, coil springs will have a negative effect on the quality of the formed product and efficiency of the manufacturing process. SPIROL® Disc Springs are the solution to form thick materials, large extrusions, and more complex designs. When stacked in series, they are capable of providing a greater, more consistent stripping force than coil springs and require less space. They have become an instrumental component in the advancement of turret punch press tooling. Visit www.SPIROL.com to learn more!

Press-independent tools, for individual use or integrated in systems.

For punching problems that cannot be solved with punching units in series and special designs, we manufacture tools and devices for every purpose.

For punching film or plastic packaging, manufactured according to customer requirements

We can produce the parts you require using specific tools or on special-purpose machines. We produce complex forms and assembly parts with strip thicknesses of 0.10 to 3.00 and with strip widths of up to 100 mm – depending on the material used. The manufacturing processes that we offer include: Punching, forming, embedding, welding, bolting, riveting and mounting. We perform the assembly of small batches by hand, while larger volumes are performed automated if you so wish. Our hybrid sub-assembly production includes the over-moulding of punched parts made of wire or metal with a variety of plastics or silicones. In order to ensure that the desired braking element features optimum properties, we make use of both the temperature durability and the haptic advantages of silicone and the weight advantage of plastic when combining these materials in this fashion. Guide tube assemblies, a combination of springs and tubes, are part of the hybrid component portfolio.
