Flat Thread Rolling

Flexibility in production has become an essential parameter in conquering new markets. It is important to produce highly customized machines according to the customer needs and strategies.

Ingramatic presents several solutions, such as: THREAD ROLLING CENTRE; which demonstrates machine flexibility, directly targeting dynamic factories present in different markets with only one production mean, the capability to thread parts after heat treatment, special parts (grooves) and studs.

For this achievement Ingramatic incorporates different feeding systems within the same machine, in order to enable it to produce both bolts and studs. The machine includes both rails and vibratory feeder for screws and a tube device feeding unthreaded studs into the introduction area. For the production of studs, the THREAD Rolling Centre utilizes a feeding system of proven reliability.

The blanks are positioned in front of the starter finger by a tube. A pneumatic separation device ensures the correct part supply into the work area. To ensure the correct orientation of the parts we have two possible solutions:

• the optimal solution is the connection of the Thread Roller directly to the Header; transferring the forged part directly to the Thread Rolling machine through the connecting tube.
• the second solution involves a vibratory or vertical feeding system, depending upon the length of the parts, with a mechanical selection device incorporating a digital camera.
• The system with a digital camera allows the control of individual parts, these parts pass on a conveyor for a control ensuring a reliable orientation. If a part is not correctly orientated, a positioning station corrects its orientation before its introduction into the tube. This device allows high production speeds even if the Thread Roller is not directly connected to the Header. The “P” or “VP” machines allow very high quality production, together with high production speeds.
• Automatic die matching systems enabled.
