Ingramatic is always in motion in expanding new technology on its I-Thread range. During Fastener Fair Stuttgart 2017 Ingramatic launched its new RP120 (W1015/TR1) and RP220 (W10/TR2) machines.
These machines are designed with the best technologies available to respond to the most demanding users. Ingramatic is convinced the RP120 and RP220 will be the most competitive thread rolling machines for building, construction, electronic, furniture and appliance fasteners.
The machines are also designed with many features ensuring rigidity and stability for running automotive parts after heat treatment.
Main features of the machines include the frame, made from pearlitic spheroidal cast iron, which has undergone thermal stabilisation before machining on SACMA’s high precision machine tools. Ingramatic also uses FEM software to develop the new design, identifying and countering stresses caused by thread rolling heat treated parts and special profiles.
The new drive in the RP220 is powered by a high precision, planetary gearbox with clutch brake. This has an epicyclical reduction gear providing a cascade reduction ratio of the gear – favouring higher torque and precision. In the gearbox, the clutch brake guarantees the speedy stop of the machine and operator safety. The RP120 is also equipped with the clutch brake. Since RP120 and RP220 come from the famous I-Thread family, the feeding rails and the vibratory feeder have motorised height positioning to facilitate adjustment according to the length of the parts. The slide is machined from high-quality, high strength aluminium alloy bar to Ingramatic specifications.
The most innovative RP120 and RP220 feature is the brand new starter unit through which control of the introduction system is achieved by a torque motor. The motion of the introduction slide is realised by means of linear movement on a guide with rollers. The machine has a main encoder that controls the encoder of the torque motor, ensuring synchronisation of the two axes.
The introducer stroke can be adjusted by the operator panel or by means of an optional electronic handwheel, which eliminates the need to make any manual adjustment with service wrenches – ensuring speed and accuracy of measure change. Blanks are separated at the feed point by a stop system that positions the workpiece on three points before it is placed between the dies (stop plate, punch and insert). Working in parallel with the insertion punch, the screw stop plate also stops the next blank from passing to prevent double insertion.
Ingramatic says it is the only thread rolling machine manufacturer supplying a monobloc soundproof enclosure. The built-in safety enclosure guarantees operator’s safety and noise reduction. The doors and panels provide easy and quick access to the work and maintenance areas. All the moving parts are protected with special covers designed with ergonomics in mind. The enclosure rests directly on the base to ensure that all liquids circulating in the machine are contained and collected. For the RP120 and RP220 a special design makes the machine very compact, reduces space requirements and permits shorter commissioning time.
SACMA Group is the pioneer in supplying the full package of headers and threaders worldwilde since 2004 and says it is the only company with a full and established range of machines completely tested and industrialised. SACMA Group is always looking towards the future.
