MANUFACTURING TECHNOLOGY T.L.M. adds to machine range
Given the ever changing demands for rolled fastening components with increasingly closer execution tolerance and on high-resistance materials, T.L.M. Srl has decided to include a two roller NC rolling machine in its extensive range.
T T
he new machine enables T.L.M. to offer its customers and potential new clients the possibility of running small batches or even pre-series batches with reduced machine set-up time. The machines can also be equipped with
special feeders which remove the rolled piece and insert the piece to be rolled between the rollers. Logically, the loading system interfaces with the rolling control CNC. Other features on the two roller NC rolling machine include:
• Electro-welded, stabilised and ground steel structure. • Mobile roller holding carriage on sliding blocks with hyperstatic dimensioning.
• Mobile roller advancement with con double ball screws for heavy loads.
• Mandrel speeds adjustable via inverter. • Roller phase search by CNC with endless angular displacement possibilities.
• Ability to store product code settings made on CNC and very quick subsequent recall times.
The two roller NC rolling machine is the latest addition to
T.L.M.’s already extensive range of rolling machines, thread rolling die and roll and segment rolling machines.
www.tlmweb.it Cold forming secondary operations
Carbex has introduced a new method of performing secondary operations by cold forming, using specially designed machines by Tze Ping Machinery Co.
he principle is an open-die, made out of two halves, which encloses the blank. Once the blank is introduced in position, the open die closes. A two blow heading station cold forms the blank inside the die and forms, for
example, a second screw head or ball shape. The die opens and the part falls down while the next part is put into position to be placed inside the closing two open-die halves. Parts are introduced by feeder vibrator bowls or special
designed devices according to the shape of the blanks. The machine range goes from blank diameters of 3mm up to 15mm. The length of the parts can be from 25mm up to 350mm
for the bigger parts. Carbex says that it is even possible to have infinite length parts with specific machine adaptations. The maximum production speeds are from 40 to 90 pieces per minute. Carbex points out that cost savings are obtained by lower
material costs, lower die and tooling costs and lower process times. A further advantage is that these machines can complete an extra operation for which an additional machine station would normally be required. Carbex is convinced these machines open many possibilities
for producing parts which now are technically and economically feasible.
