Manufactures tools for a shipyard located in northern Spain.
NEEDS OF OUR CUSTOMER
Our customer has a 500-ton DURMA press brake 6 metres long and needs new tools (punches and dies) to bend 15 m/m sheet metal with a hardness of 45 kg/mm2, for the manufacture of a new order of ships for a customer in northern Europe.
THE PUNCHES
The customer has a DURMA press brake with a special type of clamping. The punches must be designed to be very robust, with the following characteristics;
– Special clamping to fit the customer’s DURMA press brake.
– Tip with 10 m/m radius to avoid premature wear
– 60° punch angle to compensate for material bending
– Punch height of 270 m/m and width of 65 m/m, which makes the punch very sturdy
– Made of induction-hardened and ground C-50 steel
The 6 special punches manufactured in 1,020 m/m sections can be seen above.
THE DIES
The dies are manufactured with the following characteristics;
– The press brake is 6 metres long, but to facilitate the handling of the dies, they were manufactured in two 3,100 m/m sections.
– Die with a 200 m/m “V”, prepared to bend 15 m/m sheet iron without difficulty.
– 60 m/m socket at the base of the die, so that it fits perfectly in our customer’s press brake.
– Radius of 15 m/m at the “V” to facilitate sheet movement during the bending process.
– 80° die angle to compensate for material bending
– M20 thread at the ends of the die, to be able to fit a ring and facilitate the positioning operation (in addition to increasing its safety).
– Made of induction-hardened and ground C-50 steel
The 2 special dies manufactured in 3,100 m/m sections can be seen above.
