SHELLCORE MACHINE
Shellcore machine HB-10 is suitable for the production of sand cores cortical “Shell”. All functions are pneumatic. Sending sand regulated pneumatic pressure. On the equipment provided logical control mechanism. The equipment is easy to operate, economical and has a long service life. Recently, however, such equipment is not popular. The reason is the high cost of formwork, problems with heating, long preparation time and higher cost of sand “Shell” in comparison with the equipment “Cold box”.
MOLD CASTING MACHINE HS-800 x 550
HS-800 x 550 intended for the manufacture of shell molds. Stove mold equipped with a mechanism that rotates 360 degrees. Directly installed form first rotated 180 degrees and is immersed in a tank filled with sand, and then together with the reservoir completes movement, turning at 180 degrees more. In the form of hot sand poured “Shell”. Thanks to the pressure of 100-200 kg of sand in the form of turns ideal¬no clean surface. All machine functions are controlled hydraulically, there is a speed control unit. The machine belongs to a class of energy consumption “A”. Since the machine is working intermittently with long stops, it is equipped with nitrogen cylinders and hydraulic accumulators.
The maximum area of the mold plate 800 x 550 mm. For forms provided temperature control with thermocouples. The tank holds 250 kg of sand “Shell”. The machine is typically used in vertical casting. For example, in the manufacture of crankshafts (siphon, ferroalloy), solid cast objects and high lattices of cylinder liners (motors «Maguruz», «Deuths»).
THE CORE MACHINE WITH COLD CHAMBER CB SERIES
Rod machines cold chamber up to 15 kg are pneumatically operated and the machine up to 40 kg – Hydraulic. Operating pressure pneumatic machines is 7-9 bar, the operating pressure of large hydraulic machines – 75-100 bar. In hydraulic machines installed nitrogen flow and hydraulic accumulators, so these machines are energy class “A”.
In small machines pneumatic rod rod cameras can be connected to a manual or automatic clutches. You can use a wooden, aluminum or aralditovoy formwork. In large machines with high power closing formwork have to be made of steel, cast iron or aluminum. Formwork joins the machine up and running under the influence of finger pushing mechanism.
GAS GENERATOR
This easy to use, does not require periodic maintenance gas generator designed specifically for core machines “Cold box” of 0.5-30 kg. Generator provides a continuous supply of gas. The equipment has a two-year warranty. The generator comprises sealing elements not requiring frequent replacement (O-rings, U-rings, gaskets and Teflon etc.). Factors such as the progress of the curing time of complete solidification rods, etc., depend on the parameters of the core chamber. At the opening of a core plane formwork must install the O-ring, and in critical areas and deep pits – filters. Amin or methyl formate must pass through the entire volume of sand surrounding the core. The principle of operation is the injection of a liquid amine (DEMA) or beta-set (BSH-1O), followed by separation of the heating air supply under pressure of 2-4 kg / cm 2 into the core chamber. To comply with the rules of health and safety all connectors in contact with these chemicals, are made of special materials. All mechanical parts of the equipment are made of materials that comply with EU standards.
PRODUCTION Amin CORES
There are two kinds of resins, stirred separately:
1- I part- phenolic resin
2- I part- isocyanate resin
DEMA-PEA-TEA
Application:
Depending on the weight of sand, the first of the two resins is mixed in a ratio of 0.8 – 2.1%, and then the second part is mixed. Casting is recommended after two or three days after the punching rod.
PRODUCTION OF CORES “BETASET”
BSR-56 phenol formaldehyde BSH-10 gas methyl formate Application:
Depending on the weight of dry silica sand selected proportion of 1.8-2.2%.
FURNACE FOR HEAT TREATMENT
Annealing, water supply, moisturizing, softening, etc.
After each injection must be performed above operations. Designed for annealing materials installed on the truck, lined with baked bricks. The trolley is moved into the furnace. Cover the oven and truck work on the hydraulic mechanism. After closing the furnace cover material is under pressure to complete the cooking process. The insulation material used is ceramic fiber density of 128 kg / m3, resistant to temperatures up to 1260 degrees; wall thickness in the lower parts of 280 mm, for the hottest top wall – 350 mm. For heating use “NIKROTAL” or “Cantal”. Convection electric thermal alloy Cantal produced by advanced powder metallurgy advanced technology for use in high temperatures at which the convection electric thermal alloy Kanthal APM can not be used due to problems such as sagging imbalance due pereveshivaniya and wear. Due to the physical and mechanical properties of the alloy Cantal successfully used at high temperatures and heavy loads without compromising the material risk of damage. Operating voltage of the furnace can be 380 V or 660 V. To ensure the minimum flow recommended voltage of 660 V.
The equipment has a warranty period of 2 years, regardless of the nature of the technical problems.
