Control technology boosts screwdriving performance
An innovative control system gives line engineers complete control of all automated screwdriving parameters, with the ability to produce an almost infinite variety of programs.
Manual screwdriver has automatic feeding
A new low cost manual hand screwdriver with automatic feeding offers an accessible method of achieving increased production levels in a wide range of industrial applications.
It also ensures that correct screw counts are achieved, even in variable count situations, to ensure that all individual fastening points are evaluated as OK.
This level of control over the fastening process is considered to be unique to Weber, and provides a cost effective and efficient method of meeting modern production assembly targets.
Signal box monitoring is also available on the Weber stationary screw spindle units (models SA03/10/30), which incorporate automatic feed.
These products complement a wide range of screw and nut driving, riveting and insertion equipment from the company which is used throughout industry.
The HSD screwdriver features automatic feed of screws and setscrews, and can accommodate a fixed protruding screw.
Operation starts by positioning the gun unit, and pressing the trigger bar advances the screwdriver bit without rotation and locates with the screwhead.
The locking clutch then engages and the combined screwdriver/screw start to turn until the pre-determined torque is attained.
When the trigger bar is released, the screwdriver retracts ready to accept another automatically loaded screw.
Other hand screwdriver units also available from Weber include the HSK (for top heavy screws), the HSV (for restricted screw positions), the HSF (for fixed protruding screws) and the HSM (for nut driving, including flanged-nut variations).
Profiled feed tubes shaped to fit the fixing products are also uniquely used by Weber to ensure that misfeeds are eliminated at the point of assembly.
All models can be supplied with a range of optional accessories, many designed to ensure ease of use and minimise the incidence of RSI (repetitive strain injury).
These include a pistol grip for horizontal screws, a swivel holder together with mountings for weight compensation giving fatigue-free operation.
A stall detector can also be fitted to identify defective, slipping or even missing screws.
