HSM Flanging Machines
1960 Seravesi HSM Flanging Machines
The HSM are fully hydraulic machines, that complete the production of dished ends and are used for bending flanges on flat, dished, conical, elliptical, semi-elliptical or torispherical ends.
With the addition of the hot-working package it is possible to use the machine to obtain hot formed dished ends.
Flanging machines range from 12mm to 50mm thickness for cold forming and up to 100mm when using the hot forming process.
The HSM’s Key Features:
REDUCTION of tolerances thanks to the rigid structure and the precision of the machine’s moving parts and the sophisticated hydraulic system that uses proportional valves and variable displacement pumps.
The PRECISE roll movement and positioning guarantees smooth, even surfaces, free from machining marks.
HIGH PRODUCTIVITY and ease of use.
Structure of the HSM (CE certified flanging machines):
Upper and lower crossbeam and main body of the machine made of electro-welded steel plates, subjected to normalising heat treatment.
Bottom-holder carriage which supports the bottom that runs along recirculating ball bearing bushes.
Movement of the hydraulic bottom-holder carriage which supports the bottom with recirculating ball screws.
Shaping and forming rolls forged and tempered 42CrMo4 alloy special steel.
Motorised shaping roller via epicyclic reduction gear and hydraulic motor, or with electric motor in the event of electric and tilting motorisation.
Linear potentiometers mounted on each cylinder that allow electronic control of all cylinders.
The cylinders are made of alloy steel and carbon steel with a chrome-plated rod and use seals from the primary brands.
Hydraulic control unit consisting of: motor pump unit, electro valves, pressure relief valves which guarantee overload protection.
Variable displacement pumps for infinitely variable rotation of the forming roll.
Bearings mounted on the main shaft of the SKF or FAG forming roll.
Automatic centralised lubrication system with pump having an autonomous tank, programmable from the control panel.
Siemens, ABB, Telemecanique, Moeller electrical system. It consists of a fixed-console control panel on the right side of the machine for a perfect view of the (lit) work area connected to the machine with low voltage and a general cabinet where other electrical components are fitted, among which the machine control PLC SIEMENS S7.
SIEMENS KTP1200 PN control Touch Panel with a 12″ touch screen colour display. By changing pages it is possible to see on the display the position of shaping and formingrolls, to read and set the position of the bottom-holder end carriage which supports the bottom, to manage their infinitely variable rotation speed, diagnostic functions and machine alarm.
Modem to remotely control the PLC in the event of software changes and resolution of machine faults.
Air or water cooling system for hydraulic oil.
