AUTOMATION BeA’s new fastening technology
Joh. Friedrich Behrens AG (BeA) says that its new 246/130-944E and 246/160-964E pneumatic staple guns, for BeA type 246 wide-crown staples (up to 160mm), offer the right fastening solution for ever increasing insulation layer thicknesses in house building.

xternal thermal insulation composite systems (ETICS) can be found everywhere in the field of house building. Ever increasing insulation layer thicknesses also mean increased requirements for fastening technology. The BeA devices 246/130-944E and
246/160-964E reliably and quickly drive the wide-crown staples with a leg length of up to 130mm or 160mm into the materials to be joined with maximum precision. BeA highlights that both its pneumatic staple guns have
impressed professionals with their height adjustment, quick release for the fastest troubleshooting possible, a hand grip which can be used from both sides, effective noise suppression, as well as re-optimised ergonomics concerning its centre of gravity, hand grip and low weight. These features aid the user’s

work while increasing productivity. BeA produces wide-crown staples available both in strong
galvanised steel and stainless steel – in lengths from 75mm to 160mm and is certified in accordance with DIN 1052 (up to 130mm). “The name BeA has stood for maximum reliability for many
years,” says Tobias Fischer-Zernin, executive director of Joh. Friedrich Behrens AG. “Our two new wide-crown staple guns are naturally suited for construction of timber frame buildings.” He adds: “The BeA wide-crown stapling guns are powerful,
precise and versatile. Interested visitors are also welcome to see them in person at our stand at Fastener Fair Hannover, stand L17.”

When a manufacturer of hydraulic pumps required a method to permanently affix various sized bronze gears to 400 series stainless steel shafts, a solution was found using a heavy duty Spirol Coiled Spring Pin.
A T
fter press fitting the gears into position, the hydraulic pump manufacturer drills a hole partially through the assembly, installs a heavy duty Spirol Coiled Spring Pin and stakes the entrance point for maximum security.
Prior to Spirol’s involvement this was a manual three stage
process. Spirol has consolidated all the operations into one complete installation machine. As the manufacturer offered its customers many different gear/shaft assembly sizes, the machine needed to be versatile enough to accommodate the eleven existing assembly types and also had to be able to handle new variations as designed. Tooling changeover had to be quick and simple, with little to no machine adjustment. The cycle time had to be less than a minute and drill bits were expected to last at least 500 cycles. The Spirol Model DP machine consists of a standard Model CR Pin Insertion machine, an automatic, production quality,
high-precision drilling unit and a precision air-powered linear slide unit to move the assemblies between the drill unit and installation/staking station. The machine features recirculating flood coolant in the drilling operation for temperature control and chip removal; an automatic clamping/part holding fixture unit; easily interchangeable tooling to accommodate eleven different assemblies; a common drilling and pin insertion elevation between all assemblies; pin presence sensing to verify a pin has been installed in the assembly; and a machine interface for programming and control of all functions. “Spirol’s solution provides a machine cycle time of 45
seconds, drill bits yield 600 plus parts and tooling change over takes less than 15 minutes between assemblies. This machine doubled the previous production output and provided a payback of less than 12 months. The solution has also increased the rate of assembly by 400%, eliminated screw walk-out, and improved the product’s appearance and function.”

New WSK-1A welding head
Heinz Soyer Bolzenschweißtechnik GmbH says that its WSK-1A automatic welding head is ideal for applications where other welding heads cannot be used due to spatial requirements.
he new WSK-1A cross-welding head allows studs to be fed semi and fully automatically, making it ideal for use in narrow locations and areas of difficult access, especially when welding on bevelled edges and housing components. The WSK-1A can weld up to 20 studs per minute,
depending on the respective stud diameter and type of feed, and has a welding range for studs and pins from M3 – M8 or 2mm – 8mm diameter and 6mm – 40mm in length. The WSK-1A welding head can also be easily connected
to stationary machining centres, CNC stud welding machines, robots and handling systems.

Other features of the WSK-1A include: Dimensions
Compressed-air supply Type of cooling Weight
Welding material 5 - 7 bar
Automatic air cooling of stud chuck 800g (without slide)
Travel path of cantilever arm 30mm – standard (larger stroke possible depending on the respective requirements)
Steel, stainless steel, aluminium and brass
