초록 ▼

An apparatus for expanding metal and forming tubing combines two metal-forming operations into a single process. Tubing, such as that used for filters, is desirably expanded so that air or liquid may pass thru “diamonds” formed in the tubing. Expanding metal and forming tubing is accomplished in a single, continuous process by first slitting and expanding the metal, and then locking its seams to form a spiral pipe. This avoids depending on vendors for delivery of expanded metal at fluctuating prices, eliminates intermediate steps of handling the coils, and eliminates rusting while the expanded steel coils await formation into tubing. Tubing made from expanded metal may be used for air filters, oil filters, water filters, separators and other types of filters. Double-wall HVAC ducting systems or silencers can also use expanded material for reducing heat transfer and noise.

1. An apparatus for continuously perforating coilstock and forming tubing, the apparatus comprising: first and second cutter stations for receiving and perforating the coilstock, the first and second cutter stations each comprising a tool for perforating coilstock;a form roll unit that receives the perforated coilstock from the second cutter station, the form roll unit configured to form at least one edge portion of the coilstock into a non horizontal profile; anda spreader for receiving and expanding the perforated coilstock, wherein the spreader comprises first and second fixed steering plates that each interact with the respective first and second edges of the stock to place the central portion of the stock in tension, the spreader further comprising a fixed lower guide plate upon which the central portion of the stock translates. 2. The apparatus of claim 1, wherein the at least one edge portion of the coilstock comprises opposite first and second edges, wherein each of the first and second edges of the coilstock are solid, with no perforation or expansion of metal on the first and second edges before the coilstock is formed into tubing. 3. The apparatus of claim 1, wherein the first and second steering plates are positioned substantially perpendicular to each other. 4. The apparatus of claim 1, further comprising at least one lubrication device configured to receive the coilstock therethrough. 5. The apparatus of claim 1, further comprising a guide station disposed between the second cutter station and the form roll unit, the guide station configured to support the perforated coilstock traveling therethrough. 6. The apparatus of claim 5, wherein the guide station comprises a central enlarged portion to allow the perforated central portion of the coilstock to advance therethrough without deformation thereof. 7. The apparatus of claim 1, further comprising a tubing machine for receiving the expanded, perforated coilstock and forming the coilstock into tubing. 8. The apparatus of claim 1, wherein the lower guide plate with first and second side edges that engage the respective flanges upon the first and second edges of the stock and the first and second side edges of the lower guide plate each form continuous curves along a portion of the spreader such that a width of the central portion increases in a non-linear fashion along the spreader.
