DCME-series

The DCME machines (Multi slide Electric Bending Machine) are universal type automatic machines designed by BUCH® for the production, in large series, of precision shaped parts made from roll materials, be they strap or wire. DCME machines combine precision, robustness and power, along with mechanical simplicity, absence of maintenance, and facilities in the design and adjustment of their tools. The modular design of this machine and the variety of existing modules allow a machine to be supplied with the specific characteristics requested by the customer. In addition to stamping and making difficult bends, the machines in this series allow us to perform multiple complementary operations such as: threading, chamfering, welding, assembling, etc. Reducing additional processes, which, on so many occasions, make the product more expensive.

Currently, the mechanics have been simplified and an independent servomotor has been incorporated in the bending unit, in the feeding, in the stamping and in the extraction of the already shaped product. These servomotors simplify machine maintenance and allow faster tool changes and independence between the different modules that make up the machine.

DCME, A MODULAR MACHINE ADAPTABLE TO EACH PRODUCT

The multi slide bending machine are modular configuration machines composed of straightener, feeder, press and bending unit.

Straightener

To straighten the strap, we use a roller straightener.

For wire straightening, we can use a roller straightener if the developments are short or a rotating straightener when dealing with long developments.

Feeder

The feeding, both of the wire and the strap, can be done with roller feeder or with clamp feeder with stops. The best option is decided depending on the development of the part to be manufactured, the type of material and the precision we need in each product. The drive of the feeder (rollers or gripper) is by programmable servo motor, which gives us many possibilities to be able to define and better adjust the feeding times, the speeds of this, etc.

Press

The BUCH® multi slide bending machines can be equipped with presses that depending on the power we need for stamping can range from 15 to 125tn. In all cases they are “gooseneck” type presses and their construction is monobloc, which provides them with great rigidity and reliability. All presses are driven by programmable servo motor, so at all times we have monitored the effort to which they are subjected, stopping the machine if it is higher or lower than programmed.

Bending unit

In the DCME series, the bending units are circular, with two vertical tables located parallel and joined by their centers by means of a tubular support. A sprocket located between both tables and centered on them transmits the drive to the bending slides, motion shots and any other element mounted on them. The front table has a circular ring to position, at any point at its 360º, the tool trolleys, the motion takes, as well as any other accessory that must be geared to the sprocket. The rear table has holes to position the tool trolleys, motion takes, etc.

It is in this space of the machine where we usually find the extractor (driven by servomotor).

The bending unit allows the indistinct use of 2.5/5 and 10Tn tool carriers.

The movement of this sprocket is controlled/generated by an independent programmable servo motor.

The servo motors of the feeder, the press, the bending unit and the extractor are perfectly synchronized, thus guaranteeing a perfect synchronism between the three modules.
