SU113485A1 - Automated casting line with interlocking process for casting motor sleeves - Google Patents

Description

In the known structures of the device for casting sleeves, there is no automatic rolling of molds, pouring molds with metal, knocking out sleeves, cleaning the outer surface and transferring cleaned sleeves from the tumbling drum to the elevator while exposing the sleeves from the end.

In the described invention, these drawbacks are eliminated by the fact that for the automatic execution of technological operations around the ring conveyor there are corresponding devices interlocked with the ring conveyor in such a way that these devices perform operations with periodic stops of the ring conveyor.

The drawing in two projections shows the scheme of the proposed automatic line.

To melt the metal, two cupolas / and .2 are installed, of which one works, and the other is in reserve. From the cupola, the metal enters the induction electric furnace 3, from which it is fed into the metering device 4. The rotary casting machine 5 consists of a bed 6, a vertical axis 7 on which the flywheel 8 and the cover plate 9 are located. Faceplate 9 has on itself two copiers: one on the contour side in the form of a protrusion, and the other on the top plane. The latter is associated with laths, making it possible to open and close the lids of 10 forms. On the bed 6 on the ball bearings, there is a plate of the conveyor, on which the shafts of the molds are located in the radial directions. At the peripheral ends of the shafts, the molds are located, and friction blocks are mounted on the inner ends, which have the ability to move along the radial axes, which promotes traction and release from engagement with the flywheel, //. Around the conveyor

there are seven automatic pneumatic devices controlled from a central control panel 12.

When the liner approaches the copier 13, the latter inserts a tube with compressed air inside the rotating sleeve to create uniform crystallization conditions c. the inner and outer sides of the casting. The compressed air supply is stopped when the cartridge approaches the copier 14, which squeezes the tube that supplies the compressed air from the cartridge. When the cartridge approaches the next position, the device 15 removes the finished part together with the mold earth from the mold.

The device for removing the liner from the mold consists of a pneumatic plunger located in two oil cataracts. Pliers are mounted on the plunger stem, whose shoulders are connected to the cataract rods. The cleared form is cleared from the remaining molding earth in the next position by means of a device 16 consisting of a plunger and a metal brush. In the next position, the mold is filled with a molding sand mixture produced by a device 17 consisting of a plunger, a hopper with a metering device and a profiling comb located on the plunger rod.

Device 18, similar to device 17, contains graphite instead of earth in the bunker, and a knurled roller is placed on the plunger rod.

The central control panel 12 consists of a frame and two cylinders (cylinder in cylinder). On the outer cylinder are located straps connected to the air duct, and compressed air is supplied to the inner cylinder. On the outer side of the inner cylinder there are grooves, the length of which corresponds to the cycle of the operating apparatus. These grooves are connected with the inner cavity of the cylinder. In addition to these grooves, there are deaf grooves for exhausting air to the atmosphere. By rotating the inner cylinder, compressed air is distributed through the apparatus.

The cleaning section consists of a horizontally rotating combi drum 19 that has eight spiral threads on the inner side and rotating brushes 20, a stacker 21, a cage wheel 22, a pressure steel belt 23, two emery stones 24 and 25 and a bucket elevator 26 for transporting products on the automated warehouse of finished products.

The automated warehouse section consists of several consecutive bunkers 27, over which a continuous conveyor belt 28 passes, a limiter 29 and plungers 30 squeezing pallets out of the bins.

The molding material preparation department consists of a bucket conveyor 31, an additional hopper 32 with a ladle-elevator, runners 33 of continuous action, a hopper 34 for bentonite, an integrator 35 and. emulsion mixer 36.

The molten metal from the cupola / enters the induction electric furnace 3, from where it is sent to the automatic dispenser 4. The dispenser, rotating, periodically gives the necessary portion of metal to the next form. In order to accelerate the cooling of the casting, a tube with compressed air is supplied by the apparatus 13, and after crystallization is completed, it is squeezed out by the apparatus 14. The mold located on the carousel reaches the protrusion of the copier located on the contour surface of the faceplate 9, stationary on the central vertical axis 7, depresses the block from the central flywheel —and, thus, the form stops its rotational movement around the radial horizontal axis. The copier, located on the plane of the faceplate 9, with further forward movement of the mold around the conveyor moves the rail and the cover 10 opens. The mold fits into the device 15, which removes the part from it and transfers it to the receiving chute, from where it enters the cleaning drum 19. The cleaned casting enters the longitudinal spruce, the spruce of the next chute and is set vertically into the spline, spruce and lies in the stacker 21, from where, under the action of a lever, the wheel 22 enters the socket. From the wheel, the casting enters the finished goods warehouse through the chute and bucket elevator 26.
