SEO/320: THE MECHANICAL PRESS ADDRESSED TO THE MODERN FORGING
The new continuous and discontinuous cycle mechanical press
Mecolpress is proud to introduce the new model of continuous/discontinuous cycle mechanical press for hot forging, size 320 tons.
This press is designed to improve the features of all the previous machines in the size range from 200 to 360 tons. Finally just one single press will be able to guarantee the performances of the historical SEO/27 CVE-CS or SEO/36 CVE-CS presses, and it will be the new mechanical SEO/320 press, indeed!
The experience acquired in more than 50 years of activity brought us to analyze every day the forging needs of many worldwide Customers. The main topic that emerges is that the greatest force capacities are needed to deform new materials, high alloys\without lead that are considerably more high-strength.
The result is a totally innovative press that includes all the improvements that Mecolpress applied over the recent years.
SEO/320 press was born to satisfy all the new productive needs demanded by the ongoing changes in the world of “modern forging”.
Recurring problems for a forger
If you are a forge manager or an owner of a forging factory, it surely happened to you that, to satisfy your Customers request, you brought your presses to the higher limit of the performances. Consequently one of the following situations will surely happened at least one time::
- breakage of the gears, and in particular of the teeth;
- breakage of the transmission shafts;
- maintenance on bearings and clutches….
Forcing you to unexpected machine stops, with all the related inconveniences\additional costs!
Solutions proposed by Mecolpress
Machine downtimes cannot totally disappear. We must remember that we are talking about mechanical presses that forge metals at very high temperatures and that can be subjected to overloads! But these can be drastically reduced.
”Why often we say that years ago the machines did not break down?”
The answer is easy! They were sized and studied specifically for the productive needs of that time that do not coincide with the modern ones any longer!
Mecolpress answer to the new required performances in the forging operations is the new SEO/320 press that is what each forger needs today!
Technical characteristics of mechanical press SEO/320
- The machine has a monolithic structure in welded steel in order to ensure the maximum stability and duration over the year.
- The gears have a total innovative structure and extremely simplified that does not consist only in the dimensions increase, as you might think, but it consist of a series of improvements that allow the machine to work to the maximum performances without any breakage risk.
- The cushion was simplified, with the removal of the manual adjustments and of the mechanical parts generally subjected to wear.
- The flywheel was developed to guarantee enough deformation energy even at low turns. This particular characteristic is very appreciated by who has to forge the material requiring low deformation speeds.
- We have paid close attention to the ergonomic aspects: the operator can set up the tooling of the machine very quickly and without excessive efforts. Therefore you will find the equipment without tight spaces with wide visibility and, above all, safe and reliable.
We summarize in the following table the main technical characteristics of the new SEO/320:
An opportunity for the forgers
Mecolpress offers to every potential customer the possibility to inspect at least one version for each machine model at the production site based in Flero (Brescia). As a matter of fact, the main versions of the most requested models are always in production.
This results in an important advantage for you Customer because we are offering:
- the opportunity to see/experience the new machines with the support of our specialized personnel at your disposal to clarify any doubts or curiosities;
- A very competitive delivery time In case of purchase!
Hot forging of the brass: advantages of this material
The brass and its characteristics
The brass is an alloy composed of lead, copper, zinc and other metals, whose percentage can vary. The main component of this alloy is the copper that has a percentage between 55% and 62%. This high content of copper makes the brass a good electricity conductor and a material of easy mechanical machining because it does not wear out the cutting tools quickly as it instead happens for iron or steel.
Other typical features of the brass are:
- Recycling ease: brass is often remelt and reused to produce new parts.
- Resistance to a wide temperature range: during the hot forging process the brass is able to support, without creating particular critical issues, a moderate temperature range, this simplifies considerably the work, allowing a major tolerance in the usage of machineries.
- Lacking oxidation: During the heating phase inside the die, this metal is not subject to considerable oxidation.
- High corrosion resistance: the brass is a nonferrous alloy and therefore it does not get rusty.
Sectors of brass application
Thanks to its colour similiar to gold, the brass is used also for the realization of ornamental elements, home furnishing pieces such as for example handles and finishing for furniture, elements for clothing, including zippers and belt buckles.
Another sector of particular importance is composed by fluid control. This metal is particularly fitting for the production of valves, junction and fittings; since specific brass alloys with unimportant lead content were realized, the so produced pieces are therefore suitable to the contact with drinkable water. These special alloys are defined as Lead-free
In the end, as already underlined, the brass is a good electrical conductor and this characteristic makes him suitable for the realization of the electrical and electromechanical components, including switch parts, connections and terminals.
The hot forging process of the brass
The brass, that thanks to its particular plasticity permits to produce complicated geometrical shapes with simple processing, is hot forged as follows: when the press closes the dies with a single hit on the billet, it turns it into the part to be realized (in contrast to the steel that needs almost always a sequence of many hits). Inside the two halves of the die, that have the shape of the part to be realized, it is set down an enough quantity of metal in order to perfectly fulfill the entire cavity created by the two dies once they are overlapped and closed.
Presses for brass hot forging
For the hot forging of the brass it is possible to use continuous cycle presses or single cycle presses. The continuous cycle press is provided with a ram that moves continuously without stopping. The billets loading and the forged parts unloading is automatically adjusted by the electronic check. Instead, the single cycle press expects, at the dies reopening after a single hit, that the order for a new descent or closure of the dies must be sent by the user or by the PLC.
Mecolpress presses for the hot forging of the brass
For the hot forging of brass parts, Mecolpress proposes numerous mechanical and hydraulic presses with different characteristics according to the production typology that the customer wishes. Lately we have developed an innovative technology on our hydraulic presses for forging four parts with just a single hit that allows an important saving on the productive costs, come to discover how by reading the article!
