Featured Products
Straightening and Cutting Machines
RMG Stationary Cut
RMG offers the most comprehensive line of rotary straighten and cut machines available in the wire processing industry.
Our RMG line offers five models of wire straightening and cutting equipment rated for 0.050” (1.3mm) to 0.500” (12.7mm) maximum capacity. Each model utilizes the innovative, easy-to-adjust single offset – variable pitch – three die arbor, with our patented “Clutchless Cutter” for improved performance and less maintenance. RMG rotary straighten and cut machines are ideally suited for quick changeovers from one wire diameter to another and our “Micro Fine” length control allows for accurate cut length adjustments in .001” increments while the machine is running.
Standart Features
• Clutchless cutter
• Variable speed arbor
• Single die offset, variable pitch arbor
• Variable-speed, (4) roll feed heads: One feed head [14, 15], Two feed heads [16, 27], Three feed heads [28]
• Arbor, cutter and feed head powered by independent AC variable frequency drives and premium efficiency motors
• Quick-change guide bar with short travel shutter bar
• Fully-adjustable release assembly, microfine adjustment up to 1″ (25.4 mm) while the machine is running
• Perfect solution for low-carbon material
• The release mechanism can be relocated along the extension
• Sealed arbor bearing system for low maintenance and extended life
• Flexible floor plan options – Standard (left hand) and Reverse (right hand) available
• Hardened D-2 material feed rolls, cutoff die and knife
• Quick-change tooling for one wire size including arbor dies, feed rolls, cutoff die and knife
• Programmable safety shut down timer, stops machine if a feeding problem restricts wire and reduces scrap
• Programmable parts batch counter, stops machine when desired number of cut parts is reached
In-Line Wire Drawers for Fasteners
RMG offers the most comprehensive line of rotary straighten and cut machines available in the wire processing industry.
RMG and Fastener Engineers pioneered the commercial use of the in-line wire drawing process for the fastener industry starting in 1962. We are the only machine tool manufacturer in our field to have been awarded patents for innovative wire processing solutions meeting our customer’s needs. Our robust wire drawing machines are used by virtually every major fastener and bearing manufacturer in the world. RMG provides the broadest range of in-line wire drawers to the fastener marketplace, from our Model 200 for micro-formed parts to the Model 1922 for 35mm headers or anything in between.
RMG Spacesavers
Do you have space constraints? RMG’s patented Spacesaver design has helped many of our customers better utilize their valuable floor space. Our Spacesaver consolidates our in-line wire drawer with an integrally mounted turntable.
Benefits
Lower Material Costss
Saving in production costs, because pickled and limed rod or semi-finished wire is used instead of more expensive, finish drawn wire. This selection provides your company a competitive edge in high production environments.
Just-In-Time Inventory
OInventory reduction with the use of fewer basic wire diameters that the in-line drawer uses to create infinite diameters. By reducing the number of sizes you stock, your company reduces total material costs. In addition, you improve your flexibility and responsiveness to your customers changing requirements.
Exact Diameter Control
An In-Line wire drawer provides perfect, tight tolerance wire at the point of use. This benefit provides for coil-to-coil consistency. The cast and quality of your material is now optimum for feeding into your production equipment, allowing for repeatable set ups and superior straightness.
Improved Metal Formability
Freshly drawn wire is easier to straighten or form. In-Line wire drawing eliminates “age hardening” and handling damage problems that are prevalent with the off-line wire drawing process.
Improved Tooling Life
Parts produced using In-Line wire drawing require less forming force, thereby improving tooling life. In addition, consistent volume control means consistent heading tonnage which, in turn, consumes fewer tools.
Improved Wire Conditions
In-Line wire drawing provides a constant flow of clean and controlled wire to the production machine, as the wire has no time to oxidize, deteriorate or be damaged from sitting in inventory waiting for production. Even with the best handling practices of finished wire, it can have imperfections from the recoiling process and transportation. When off-line drawn wire is recoiled, the cast, condition and quality of the wire is compromised. Surface and substrate imperfections, from the recoiling process, introduce variations in the cold-forming process.
Elimination of Short Feeds
RMG In-Line wire drawers provide a “storage loop” of wire and isolate the weight of the coil from the feed system of the production machine. Our wire drawing machine matches the production machines wire requirements, keeping a constant supply of “load free” wire always available.
Reduction in Downtime
Larger, heavier coils can be utilized. The wire drawer is a huge winch capable of pulling the heaviest of wire coils. By isolating this weight of the coil from the feed system of the production machine, your operators can set the feed pressure for the correct operation of the production machine without concerning themselves with the weight of the coil.
Standart Features
• “Patented” one-way clutch wire relaxer rolls provide more tractive force by preventing slipping of the last wrap of wire
• Durable through-hardened D2 tool steel capstan
• Heavy duty planetary gear box Models 500 thru Model 1922 (Model 200 high torque gearmotor)
• Full capstan cover with electrical interlock
• Full machine enclosure for reduced maintenance costs and safety
• Two hand jogging with all operator controls conveniently located out of wire line
• STARTGARD (production machine interlock) prevents starting of header if the wire drawer is not set to automatic operation, and shuts down header if there is a fault from the wire drawer
• SLIPGARD (forward compensator over travel switch) signals the header to stop if the capstan cannot produce wire as fast as required
• Energy-efficient, variable-frequency drive with premium efficiency motors are over 50% more efficient than older hydraulic technology, saving thousands of dollars on an annual basis, and they are environmentally friendly and reduce maintenance costs
Integrated Multi-Roll Wire Straighteners
for the Fastener Industry
RMG offers a broad range of wire straighteners that are ideally suited for the fastener industry. Our unique design of wire straightener machines provides the ability to control the wire’s straightness with a single-knob control, in addition to the capability to accommodate a wide range of diameters by using the same frame and simply changing out the straightener rails.
Standart Features
• Single adjustment straightness controls on wire straightener
• Quick-change rails to increase the overall diameter with the same base
• Sealed, double row bearing construction on wire straightener
• Mounting capabilities for a stand-alone bench, integrated into an uncoiler, pre-feeding line or the exit side of a wire drawer
Special Wire Straightener Feed Lines
Many of our customers have asked for solutions to their unique production requirements. We have designed and built units to meet these needs using hydraulic power units, pneumatically actuated adjustments, feed and control systems.
Wire Pointers
for the Fastener Industry
Wire Pull Pointer Assemblies are supplied as standard equipment on our Models 200 through 910 of fastener wire drawers. It is always necessary to provide a pointed end when setting up a wire drawing machine. Although butt-welding a slightly smaller wire to the head end of the wire to be drawn represents one common method of providing the pointed end, under some circumstances, it is more practical to use a pointer. This technique “necks down” a section of the parent wire and permits it to be inserted through the drawing die for initial setup.
