South Africa Foundry Laboratory Project
The project is a foundry laboratory project in South Africa. The production cycle is 70 days. Because it is a brand new project, it is a complete set of hand-molded casting equipment, equipped with an intermediate frequency induction heating electric furnace and cooling tower, and S24 furan resin sand mixer , S11 green sand multi-mull, Z14 Jolt-squeezing moulding machines, sand testing equipment (hardness tester, moisture analyzer, strength tester, air permeability tester, etc.), dual-head hot core box core shooting machine, surface Cleaning up shot blasting equipment, etc., to form a semi-automated green sand casting production line and furan resin sand casting production line.
The molding equipment of the green sand casting production line adopts Z14 Jolt-squeezing moulding machines, which can be used with hand-molded casting sets to repair the sand tires. At the same time, it is equipped with a sand ramming hammer to improve the compactness of the molding sand. Green sand mixer With S11 multi-mull, it is necessary to manually add green sand, coal powder, bentonite and water, because there are errors due to manual addition, but if a quantitative device is used, it can directly solve the uneven feeding caused by manual errors and the error of molding sand compaction. Humidity error, etc. However, since the equipment is used for casting training, it does not need to be used efficiently, and the auxiliary materials can be added one by one after weighing with an electronic scale.
After the green sand is mixed, put the mixed green sand into the moisture analyzer through the sampler to determine the moisture content in the molding sand, which can be sampled and tested. After the data is recorded, the auxiliary materials and water are added in proportion to the sand. After molding, the hardness of the sand mold is measured by a hardness tester. The hardness of the molding sand produced by the microseismic molding machine can reach 85 or more. Before molding, the tensile strength, hardness, and shear resistance of the molding sand can be measured by the universal strength tester to ensure The quality of the sand mold and the air permeability detector are mainly used to detect the air permeability and heat dissipation of the sand mold, to ensure that the sand mold can quickly exhaust and dissipate heat during the casting process, and prevent the casting shot from damaging the sand and causing the casting to be abnormal.
Furan resin sand casting production line adopts S24 single-arm self-hardening sand continuous sand mixer, equipped with PLC control system, furan resin and curing agent are automatically added through the resin pump and curing agent pump imported from Italy, quantitatively accurate, and the sand mixing arm can achieve 270° Rotation, if equipped with a three-dimensional tapping table, the compactness of the sand will be better.
In order to improve the yield and quality of the castings, the sand core is made by the dual-head hot core box core shooting machine, and the sand core is buried in the sand mold. The hot metal liquid melts the resin of the sand core during casting, and the shape of the casting is After the molding sand is cooled, the casting and the old sand are separated by the sand shaker, the old sand and sand core are recycled, and the casting enters the shot blasting area for surface treatment.
The shot blasting machine adopts a small hand-held sandblasting bin with pneumatic sandblasting. The working principle is similar to that of a sandblasting tank. The equipment is equipped with a dust removal system and a steel shot recovery system. It does not require an external dust collector. The equipment can be transported according to the working conditions of the workshop. , The top of the equipment is equipped with a lifting device.
