New Developments in Clamping and Locking

In the area of clamping and locking, Winco offers numerous toggle clamp versions for any conceivable application. To better meet specific customer needs, the toggle clamp product range now also includes a wide range of new developments and improvements as well as an expanded selection of accessories.
Toggle-Clamps–Range-Extended
The standard parts specialist, Winco has optimized its portfolio of toggle clamps with regard to handling, quality and assembly, bringing innovative new products into the market. For example, product versions with integrated safety features are now available, effective immediately. The toggle clamp GN 820.3 is protected by a safety hook against unintended opening and the associated operating errors. The safety locking can be released with a single hand, if necessary. In the product version GN 810.3, both end positions of the clamp can be secured with the new locking function. This enables the use of longer clamping arms without them being closed accidentally.

As a new service, Winco delivers the matching spindle assembly with toggle clamp orders and also, if desired, the extended clamp arm, making procurement and assembly even easier for the customer. All Winco toggle clamps are available in steel or stainless steel, manufactured from sheet steel or forged parts and with galvanized or black-coated surface. Depending on the specific application, customers can choose between vertical clamps with vertically oriented clamping lever, horizontal clamps with horizontal lever as well as locking clamps and push-rod clamps. Thanks to the extensive selection and accessories as well as the numerous new developments, such as longer or wider clamp arms, Winco ensures that the ideal clamping product is always available for every customer requirement.

The base element of the toggle clamps has also been improved and supplied with slot-style hole patterns to enable universal mounting to any hole patterns typically found in industry applications. These are now compatible with both American inch dimensions as well as with the metric system. This makes it considerably easier to fasten the components, such as to a production machine.

Opening and closing with specialty hinges from Winco

From simple hinges for welding on to multi-joint hinges with complex kinematics, the Winco selection has everything needed for superior door and flap solutions—Including extra functions.

Opening and closing with specialty hinges from WincoYou might think that when it comes to opening and closing, all the possibilities of hinges have
already been exhausted. Not even close. Winco regularly succeeds in making further improvements to hinges, adding practical extra features or creating designs for very particular niche applications.

For heavy duty applications, for example, try hinge GN 237.3, a compact, heavy duty hinge of stainless steel. With a 180° range of motion, these hinges can stand up to even high dynamic wear—regardless of the mounting orientation—thanks to special shim washers. Depending on the selected type, the hinge bands also have centering extensions that ensure a tighter fit—preventing sliding and eliminating the transverse forces that otherwise place extremely heavy loads on the screws. The hinge pin is secured against loss by a recess and supplied with lifetime lubrication. An asymmetrical band arrangement and the associated possibility of a third fastening hole proves its value especially when mounted in areas with thinner material cross-sections.

The hinge series GN 235, on the other hand, can be mounted with socket head cap screws and—thanks to the offset axis—still swivels by 180° without collision. Horizontal and vertical slots simplify adjustment, and the hole pattern corresponds to existing hole arrangements, making it easier to replace existing hinges.

Additional functionality is offered by hinges with variable friction, and in another Winco-Norm part, an integrated spring ensures independent return of the hinge. This special product range, which also includes integrated damping, indexing and locking functions, is being continually expanded by Winco.

One kinematic highlight is already available from Winco: the multiple-joint hinge with either a 4x, 7x or 10x joint mechanism, which opens flaps and shifts their position at the same time. 180° is also standard here, and the internal installation once again makes use of slots.

With its design hinges GN 138, Winco offers solutions for appearance-sensitive applications: the closed hinge body of die-cast zinc hides the fastening screws and is available in various sizes—soon also in stainless steel.

Oil and water repellent membrane

With a pore size of 1.2 µm, oleophobic and hydrophobic membranes GN 7404 provide reliable aeration and ventilation, allowing no dirt particles or droplets of oil or water to pass through the membrane.

Pressure-Equalization-Plugs-Aluminum-Oil-Water-RepellentIn order to compensate for pressure differences in both directions, JW Winco already offers various aeration and ventilation elements with integrated filters and sieves. As a new change to its product line-up, JW Winco now also offers elements equipped with membranes alongside these standard parts. This makes it possible to prevent even smaller particles and, above all, oil and water droplets from passing through the ventilation openings. Dirt and moisture are kept away from the inside of the housing, and lubricants such as oils cannot escape. While the previous filter and sieve elements have a minimum mesh size of 100 µm, the standard membrane pores are only 1.2 µm in size.

Externally, the robust membrane is additionally protected against mechanical stress by a protective sieve made of stainless steel. Ideally, the standard part GN 7404 should be installed in vertical surfaces so that no liquids can collect on the membrane, which could impair the pressure balance. At a nominal differential pressure P1 to P2 of 1 bar, the maximum air flow – depending on the diameter – is up to 34 l/min. The membrane even retains its function up to an external pressure differential of 2 bar or an internal pressure differential of up to 10 bar. The maximum operating temperature is 212 °F (100 °C).

The membranes themselves are made of a nylon fleece impregnated with an acrylic copolymer, and although the fibers are wetted, the porosity remains unchanged and can range between 0.2 and 10 µm if desired.

Using a special process, the membrane is robustly bonded to a plastic ring socket by injection molding so that it can be firmly inserted into the stainless steel or aluminum screw fittings, sealed by an O-ring.

Effective pneumatic clamping

Pneumatic toggle clamps fix workpieces in place, position mechanisms and hold molds together. In this way, they not only simplify handling, they also enable fully automated processes. JW Winco offers a number of flexible solutions for this purpose.

Toggle clamps of the series GN 860 and GN 862 feature an important unique property: Using the
Pneumatic-Clamps - Range Extended
over-center principal, which provides a positive lock during closing, the retaining force is maintained even after loss of pressure at the cylinder. The low-wear design as well as the option to detect the position of the clamping element by means of magnetic sensors offer additional dependability. The retaining force itself is transmitted to the clamping point by a clamping arm or piston rod. A hybrid toggle clamp employs a hand lever to combine manual closing with pneumatic opening – an important feature for clamping applications requiring individual clamping but simultaneous, fast and automated releasing.

The compact power clamps of series GN 864 and higher are also designed to remain in the clamped position after a pressure loss. The sophisticated kinematics ensures that the setting action is fast while the actual clamping movement takes place slowly, making pneumatic end stop dampening unnecessary. The available types differ in terms of their clamping motions and are each sold in four sizes with astonishingly high retaining forces of up to 13,300 newtons. These clamps feature high stability, long lifespan and low compressed air consumption. The offering is rounded out by various mounting options and a large range of accessories from adjustment plates and blanks for individual jaw shapes to directly attachable proximity switches.

The swing clamps of the series GN 875 / GN 876 perform two motions: The clamping arm first rotates by 90 degrees from its resting position, then travels in a linear motion down onto the workpiece in the actual clamping stroke. Thanks to the rotary movement, either to the left or the right, the workpiece remains accessible from above, allowing it to be positioned and removed directly. The freely selectable mounting brackets as well as the various clamping arm designs allow the clamps to be adapted to the specific situation. There is even a completely customizable adapter flange. The swivel clamps are available in block design with T-groove mounts for end stop sensors or in a compact design with male thread which can be easily mounted in a height adjustable fashion using a threaded adapter flange.

Steel and Stainless Steel Vertical Acting Toggle Clamps, Safety Hook and Vertical Mounting Base Available from JW Winco

JW Winco, Inc., A Ganter Company, a leading supplier of standard industrial machine components, now has available GN 810.4 Steel and Stainless Steel Vertical Acting Toggle Clamps, Safety Hook and Vertical Mounting Base.

These vertical acting toggle clamps have two locking features in both the closed and open positions. In addition, they have a safety function whereby, during closing, a spring-loaded safety hook latch ensures a secure locking connection. “This feature prevents the inadvertent unlocking of the clamp due to vibrations or an accidental attempt of loosening or opening the clamp,” said John Winkler, CEO, Office of the President at JW Winco. “Used not only on jigs and fixtures to hold raw material for machining, these toggle clamps are great for applications requiring any type of hold down, such as lids, flaps, and quick-change components.”

In the clamped position, the operating lever is in its vertical position. To open and release the clamp, which is a one hand operation, the user presses the main operating handle and the grip of the safety hook latch together to disengage the latch mechanism. “The clamps work according to the toggle principle, as the lever and clamping bar move in the same direction,” Winkler said.

In the steel version, the toggle clamp is made of case hardened steel with a zinc plated, blue passivated finish. The bearing pins are tempered while the bearing rivets are case hardened. The stainless steel version is manufactured from European Standard No. 1.4301 (AISI 304) material. The hand grips are made from a high quality, oil resistant red plastic, and all moving parts are lubricated with a special grease.

JW Winco Now Offers Gripping Trays – for a Streamlined Grip

Elegantly covered or visibly bolted, available in a variety of surfaces and colors: The gripping trays GN 7330 and GN 7332 are new additions to the extensive standard parts selection of JW Winco.

Gripping-Trays-GN-7332-GN-7330JW Winco, Inc., A Ganter Company, a leading supplier of standard industrial machine components, now offers GN 7332 & GN 7330 Gripping Trays with front or back mounting options.

In contrast to typical handles, gripping trays offer the advantage that they are flush to the surface, making them appropriate for applications that require saving space. Typically used in the packaging, medical, printing, woodworking, transportation, and material handling industries, the gripping trays are used for the pulling or lifting of cabinet doors, door hatches, and entry doors. “The gripping trays can be mounted either from the front / operator’s side with countersunk screws or from the back with threaded studs,” said John Winkler, CEO, Office of the President at JW Winco. “In addition, both gripping trays are available with or without sealing.”

With the sealed front mounting versions, countersunk sealing screws together with the sealed back side of the gripping tray, prevents the entry of fluids or dust getting into the housing interior where the tray is being mounted to.

The GN 7330 gripping trays are made of die-cast zinc and supplied with a powder coating in either black or silver. Coating in a different color is available upon request.

The GN 7332 stainless steel gripping trays are made of high-quality deep-drawn, rust-free stainless steel with the surface blasted to a fine matte finish.

On each of the versions, the threaded studs used to mount the tray from the back are not visible from the front.
