FOUNDRY

Evolut shares its consolidated experience in the most varied sectors related to the Foundry sector, be it Cast Iron, Aluminum or Steel.

Steel

The deburring of steel castings, can be divided into two different solutions:

  • With jets handled by the robot for weights up to 200 Kg and machining operations on stationary machines, with possibility of different feeding systems:
    - Random with the aid of the vision system;
    - Palletized jets with rotating stocks; - • With belts without references with the aid of the vision system.
    The deburring units are compensated and feedbacked. The wiping speed is controlled according to the quantities of burr on the jet. The wear of the grinding wheels is handled by the laser reading system.
  • • With spindle manipulated by the robot and jet fixed on motorized positioner for weights above 200 Kg.
    The spindle allows a rapid change of the tools, with consequent downtime reduction.
    The tool changer offers maximum flexibility and availability of different tools. the wear of the grinding wheels is handled by the laser reading system.
    The productivity ratio of a robotic deburring island with respect to the manual one is 1 to 4.
    The 3D programming software allows to set up the island in 15 minutes against the usual 8 hours. This involves a drastic reduction of the island downtimes with consequent greater production flexibility and the possibility to manage lower minimum lots. Virtual simulation allows to know the times of the production cycle on a jet before starting production.
    It is possible to provide turnkey plants with soundproof cabins complete with suction system.

Aluminium

Aluminium cutting, deburring, grinding and satin finishing

The island is able to handle pieces up to 120/150 kg in the case of pieces handled by the Robot, without weight limits in the case of pieces resting on the table. The productivity ratio of a robotic island with respect to the operator is 1 to 4. The island can be fed in random with the aid of the vision system, on pallet with revolving stores, belt stores. Retro activated and servo systems for the compensation of the robot gripper. The island allows a rapid change of the tools, with consequent downtime reduction. The tool changer in the case of the spindle being manipulated by the robot offers maximum flexibility and availability of different tools. The 3D programming software allows to set up the island in 15 minutes against the usual 8 hours. This involves a drastic reduction of the island downtimes with consequent greater production flexibility and the possibility to manage lower minimum lots. Thanks to a virtual simulation software it is possible to know the production cycle times. It is possible to provide turnkey plants with soundproof cabins complete with suction system.


Cast Iron

Cutting, deburring and mould assembly plants

The island is able to handle pieces up to 120/150 kg in the case of pieces handled by the Robot, without weight limits in the case of pieces resting on the table. The productivity ratio of a robotic island with respect to the operator is 1 to 4. The island can be fed in random with the aid of the vision system, on pallet with revolving stores, belt stores.

Thanks to a virtual simulation software it is possible to know the production cycle times. It is possible to provide turnkey plants with soundproof cabins complete with suction system.

Mould assembly

Inserting cores with heavy loads; Greater repeatability and accuracy of inserting cores with reduction of waste and of the inclusions on the castings; Possibility of feeding cores from a pallet or on conveyors without references thanks to the recognition of the position and orientation during pickup with vision system Evolut.


Gravity Casting

Gravity casting plants have the following characteristics:

  • Drawing the liquid metal from crucible holes with the determination of the metal by thermocouples, or self-levelling furnaces;
  • Serving up to 4 shell die casting machines and n. 2 metal feeding furnaces;
  • Possibility of pouring into moulds with or without cup up to 4 cavities;
  • Use of the seventh external cup movement axis entirely designed by Evolut.
  • Maximum weight of metal: about 100 kg

Type of cell:

  • With fixed or pivoting chills installed on the ground;
  • With chills installed on multi division rotary tables;
  • With self-levelling tank furnace;
  • With double crucible furnace.

In all the cells there is the possibility of carrying out the change of die-casting without interrupting the automatic cycle of operation the robot. The pouring cycle programming takes place by synoptic with simplified operator interface and with dedicated keyboard, that make the definition of the points and of the process simple and intuitive.

Die-casting

Machine unloading times drastically reduced.

The island can be designed providing a mould lubrication step with the use of an additional robot. In the event of a fault, the software of automatic repositioning, allows you to move the robot out of the machine by pressing a button. It is possible to realize personalized study for the deburring of the work piece directly at the outlet of the press, saving in this way 1 man passage and the elimination intermediate storage warehouses.

Various

Coating wax moulds

Robotised cells for lost-wax cores coating: -maximum weight that can be manipulated of the bunch (mould)finished: 200 kg -possibility to handle different types of material, and glue tanks in function of the coating process. The supervisor of the line, manages the recognition of the bunch (mould) present on the line, the number of coatings and the typology of the material assigned to them, as well as the drying time of the various layers. The bunch (mould) completed is automatically unloaded by the coating line for subsequent operations.

Hot moulding

The robot can manipulate pieces with temperature up to 1100°C and, if necessary, can be equipped with liquid-cooled gripping systems. The robot is protected from the irradiation of the heat of the piece being manipulated by special systems of air-conditioned cover systems. In the case in which the pieces fed from the heating furnace do not have a referring and repetitive position, their recognition is carried out by cameras and vision system. The robot can serve more than one press in function of the cycle times and of the temperature loss of he detail. The forged pieces can be arranged on special cooling storage and shaping compartments before being unloaded into the boxes.

Cores painting

-Possibility to manipulate more cores with multigripper gripping systems: -rotary gripper which facilitate dripping after immersion in the coating product.
