JOEST Shakeout with electronically adjustable oscillation parameters

The machines were delivered to Croatia during the second fiscal quarter of 2021. Commissioning is performed and overseen by JOEST and is planned for this summer. The client ‘s demand was to provide a reliable Shakeout that could handle a large spectrum of parts whilst maintaining a small form factor due to space limitations on site. The machine should separate as much sand as possible without damaging the casts made of GERMANY. Cast-/Sand-Shakeout after green sand forming line. JOEST Shakeout with electronically adjustable oscillation parameters gray cast iron and spheroidal graphite iron. The client’s molding plant type HWS EFA-SD 5 with molding boxes of 1000x920x650 mm produces a maximum of 80 molds per hour. Roughly 2000 different parts are produced, the heaviest weighing 300 kg. The temperature of the casts is around 500 °C when they reach the shakeout. The individually designed Shakeout measuring 1500 x 5400 mm is fitted with manganese steel trapezoid grates with zero overlap and four discrete drive cells. It also features sump-lubricated bearings and a triple seal. All side walls are completely free of welding seams, the beams are riveted or bolted. The oscillation angle of the JOEST Shakeout lies between 50-85° with an oscillation frequency of 16-25 Hz. The de- FOUNDRIES #01 2021 53 manded oscillation parameters are binarily transferred from the shift register of the molding plant, located at the discharger, to the S7 control unit of the Shakeout.

The JOEST Shakeout is followed by a feeder with dual-lane discharge. The feeder prevents damages to the casts due to its design with a low acceleration and gentle conveying movements. It also features minimized noise emissions, an ergonomic cast handling as well as special low frequency drives. The design is environmentally friendly and ergonomic for the employees. The advantages are a bolted/riveted design with weld-free side walls as well as the special grate geometry that prevent blockage and enables a high sand discharge capacity. The reliable drives with multiple seals and thought-out heat management in addition to the adjustable oscillation parameters according to the molds were another reason for choosing JOEST. The controls and drives with Siemens standard parts, standard motors and without incremental or absolute encoders that are prone to failures, were able to convince.

#cooling, #sorting & #batchloading

JOEST delivered several types of machines from its product portfolio for castings for a customer‘s complete system. To simplify and enhance the original process of storing casting parts in boxes for the cooling process, a JOEST Casting Cooler was installed downstream the existing shakeout.

JOEST USA Special Charging Feeder

For foundry melt shops the challenges start at the beginning with charging cars. Generally used to provide scrap, virgin ore and alloys to the charge furnace, they must be designed around each customer’s particular type of materials, furnace interface and processes.

JOEST Spiral Crusher with Shakeout

Bosch Rexroth is modernizing its existing process of emptying die-casting molds by implementing a new casting-sand separation and recovery plant. Once the casts are freed from their molds, they are separated from the sand which is processed and reused. The task for JOEST was very complex. The focus was on the emptying process of the molds and to break down the sand and clean it. The sand is then returned to the casting process. On site, the machines will be placed in a space that was previously occupied by a furnace. A large chamber in which the furnace used to stand, connects the factory floor to the basement.

Four-way travelling JOEST Charging Vehicle

For the optimization of the foundry and to improve the production process, the Bosch Rexroth AG in “Lohr am Main” is adding a third furnace to its automatic charging system which currently features two furnaces. For this project, a new furnace platform is being built in the neighboring building. The task for JOEST was to find a solution, so that the existing feed equipment for the furnace Charging Vehicles could be reused. The vehicles are fed with metal scraps and additive materials needed for the melting process, both of which are bound to their original location.
