Push furnaces tgv series

The push ovens of the TGV series (with vibrator gas turbo) are indicated for all productions from small to large series. In relation to the speed and the required productivity are available combustion chambers of variable length from a minimum of 1500 mm up to more than 6000 mm. The furnaces are available with varying tracks numbers, from 1 to 14 until today. The most machines built, using the system to 4 tracks, which guarantees a very flexible machine, which can range from small productions to very easily mass production with small and simple adjustments.

The main advantages of the machine are:

  • Huge flexibility in production
  • cost contents of the chamber with respect to a chain counterpart
  • Reduced consumption of gas and electricity
  • Reliability over time, even on 3 shifts
  • always available parts and easy to replace
  • Extremely easy to use
    The wheelbase of the tracks can vary in function of the billets to be heated, and is normally available in the sizes 50, 70, 80, and 100 for the 4 tracks and multiples thereof, while distance 80, 100, 110, 120 for the two tracks. For the 6 tracks are available 75, and 80. For other furnaces using tracks with custom sizes.

The oven that most commonly corresponds to the needs of the customer is the wheelbase 4 tracks 70 mm.

The traks, of a new type, consist of modular units made of silicon carbide, offer greater durability, resistance to temperatures up to 1650 ° C, great smoothness and less oxidation of the material. They are also available in stainless steel Heat-slopes for temperatures up to 1200 ° C suitable for the heating of small parts. On each track acts a row of burners with independent regulation, so as to ensure maximum uniformity of temperature on the billets file.

The oven chamber is built by following a Maestri now validated production process that goes from the selection of the most suitable mixture, we studied with our technology partners, to 'preparation of the molds of the part by our workers, to the jet, and drying according to a procedure that since the 50s has guaranteed to our chambers reliability and superior durability over time, as well as the ability to quickly bring the chamber in temperature at the beginning of the day, thanks to the stability gained by the elements that allows to push the oven at maximum power without a pre heating.

The heating is made with gas burners (methane or LPG) high-speed, designed and produced by Maestri. Divided evenly inside the chamber so as to make the temperature uniform, though guaranteeing an independent adjustment on each track. The distribution of the mixture system is completely designed, constructed and verified by the staff of the Maestri, including the burner heads of our domestic production of special alloy.

At the exit of the chamber usually heating furnaces are equipped with a reincolumnator easy adjustment that provides to put in a column hot billets on one or more files.

All ovens of the TGV series, unless special needs, assemble the heat exchanger Maestri that raises the thermal efficiency of the furnace by limiting the consumption of gas up to 25% and the new thermal regulation and control system of the fan speed (patented), which also contributes to reduction in use of gas and electricity, guaranteeing a better thermal regulation and reducing noise of the machine.

The maximum temperature working inside the chamber is 1100 ° C.

The orientation of the billet is made with a vibrating plate provided with selectors rollers. The billets are conveyed correctly in columns to the hydraulic pusher system, a unique feature of our ovens, which guarantees sturdiness and reliability, to then be pushed inside the chamber by means of four independent cylinders, operated individually or in pairs. The thrust stroke is recorded by pressing a knob, while the cadence is given by adjustable timer or by impulse coming from the press (optional).

All series of ovens provide for a rapid emptying of the exhaust system without having to pass from the chamber

The electrical panel is integrated into the machine, and therefore does not require additional space. The operator panel is located in front of the machine and assemble termoregolator elements and the touch control panel flanked by physical keypad. A further and speculate set of commands related to the load is located adjacent to the same zone.

PUSH TGV SERIES GALLERY


PUSH FURNACES TGVA SERIES

They are the pusher-type furnaces for the production of forged aluminum, which, while maintaining a close resemblance with ovens of the standard TGV series, differ for the method of heating which here is indirect, that is carried out through the ' air heated by means of radiant tubes so as not to oxidize the material, which unlike brass, suffers much in terms of the final quality and sliding in the mold.

Usually, for reasons of space these ovens are spread over 12 or 14 tracks in order to ensure a rate of about 30-35 pieces per minute, provided to modify the length of the chamber as a function of obtaining a well sized machine according to the specific needs of the customer .

The tracks, working at much lower temperatures than brass, are made of special steel and non-silicon carbide, since the working conditions less onerous.

To standardize the intake of billets to the vibrator in the loading zone, the supply chain of the rocker material upstream of the pusher, arranging the pieces in equal measure on the vibrator.

The push for economic reasons, on the furnaces with many trails can be built in the pneumatic version, which ensures the correct operation reliability, but certainly lower than hydraulic push which is always available and recommended.

CUSTOMIZING MACHINES

All Maestri ovens are compatible with a variety of equipment and controls that are not always included in the standard machine, as these are essential in some cases but not very useful and not justifiable in others.

In red are highlighted devices or the devices highly recommended by Maestri.

STRUCTURAL ELEMENTS OPTIONAL

  • load of the billets by means of Cartesian axes 2 movable axes directly on the track system System. (more accurate and suitable for large pieces, but limited speed ensures precision and delicacy in release more)
  • charging system of the billets through system 2 mobile Cartesian axes of vibrator. (much faster, it allows to have more pieces simultaneously on the vibrator and ensure a bit 'warehouse on the plate and thus speed up the load)
  • Implement the hearing protector of the machine through a casing and rear-end collisions ad hoc.
  • The emptier system of hot billets at the end of the work cycle, which is a system that allows you to empty the chamber even when there are no more pieces in the hopper and print to the last billet, simulating the pressure and not interrupting molding cycle until the end.

ADDITIONAL CONTROLS THE TEMPERATURE

  • multi zone system. The room is composed of n zones, according to the needs and to the length of the chamber, usually 3, independent of each other, which allow to heat the billets according to a controlled ramp and / or work with fewer areas compared to the total in the case of particular needs, making the machine very flexible.
  • Optical pyrometer on a billet at the exit of the oven with integration Software-Hardware
  • Optical pyrometer on a billet at the exit of the oven with integration Software-Hardwarepyrometer multi-modular system with a device for the area (including SH)
  • pyrometer multi-modular system with control of the outlet of each single row. (S & H included) This solution is recommended for molding of critical situations, where the accuracy of the temperature in the molding has an enormous influence on the quality, strength and durability of the finished product.
  • Synchronous press, which adjusts the speed of dispensing of the pieces from the oven according to the velocity of the press
  • anti fusing system in two guard levels, which acts on the temperature control in the event of downtime on the press.
