The invention relates to a foundry, in particular, equipment for the manufacture of bimetallic parts. There are known devices for the manufacture of bimetallic parts by the method of deposition of liquid metal on a solid base, containing a multi-platform table with casting molds and a mechanism for its rotation, an inductor and mechanisms of rotation of casting molds, drives for vertical movement of parts and a knock-on: a Cl3 mechanism closest to the proposed technical entity the achieved result is a plant for the manufacture of bimetallic parts containing a multi-position carousel table with molds installed on it. s, the rotation mechanism with position locking and price tral column having a console with a pivot drive, the inductor; placed above the table at the position of heating, driving the vertical movement of the part to the inductor and rotating it during heating and pouring, the filling device, the removable mechanism and the harvesting conveyor, the manipulator of the movement of parts above the carousel table, made in the form of two grippers of the parts placed on the ends of the lever fixed in its upper part with the possibility of vertical movement on the console of the central column, and the device for turning the parts mounted on the central column, with the drive of the detail Whether from the pickup position to the position of the mold underframe, a removable mechanism made in the form of a receiving table with an extension groove along the longitudinal axis and with drives of horizontal movement and inclination and the angle of dropping the sliding parts onto the harvesting conveyor C 2,. A disadvantage of the known installation is low productivity due to frequent breakdowns of parts during the Leranos period by the manipulator over the table. The gripper design with the upper arrangement of the pneumatic cylinder is ineffective, since the grippers enter into the inner hole of the part and slide off the part with insufficient pressure. The absence of a deposited layer in the control circuit of the sensor excludes the mechanism for removing parts from the General Automation Scheme. Manual control of the removal mechanism leads to a decrease in the performance of the installation. The design of the manipulator with a large number of actuators is very complex and not convenient to maintain. The purpose of the invention is to increase the productivity of the installation and simplify its maintenance. The goal is achieved by the fact that a plant for manufacturing bimetallic parts containing a bed, a multi-position carousel table with molds installed on it and a rotation mechanism with a pin-clamping locking mechanism, an inductor located above the carousel table at the heating position, drives the vertical movement of the part to the inductor and rotating it during heating and casting, the removable mechanism and the manipulator are equipped with a weld layer alarm device mounted on a fixed bracket in front of the position It is removed and made in the form of a spring-loaded two-armed lever, at one end of which a contact bar is fixed, on the other - a contactless switch flag, and the manipulator is placed near the carousel table at the heating position and is made of two hinged grippers in the form of a mechanical arm, driven to move in a horizontal direction and rotate on around a horizontal axis, as well as drives for two-step movement in a vertical direction, in this case (the center of gripping the mechanical arm is located n on the axis of vertical movement of the mold parts to the inductor "The drive for moving the two-stage mechanical arm in the vertical direction is formed in .vide two paired cylinders, a lower rod which is attached

the directional part 62 is placed in the form. By turning the carousel table 3 by the mechanism 13, the weld part is fed to the position of heating and turning the parts. The carousel table is fixed by a pneumofixer 16, and the weld piece with the help of a pneumatic cylinder 19 by a rod 9 is lifted into the inductor 20, where the upper surface of the weld is heated to the welding temperature. During heating, the part is rotated by the rotation drive 17. The mechanical arm 28 of the manipulator is fed into the inductor area and the grippers 29 captures the part. Using the pneumatic cylinder 25, the part is lowered and fixed at half the distance between the inductor and the mold, then rotated by a 180 ° rotation mechanism and the pneumatic cylinder 26 is lowered by the heated weld surface to the mold. The arrangement of the manipulator at the heating position allows for an increase in the productivity of the installation in the manufacture of parts with two overlapping EFs planes due to overlap. one position of the heating and rotate operations for ISO to place in the mold the weld layer. In addition, the design of the installation is simplified by arranging all the actuators in the design of the manipulator and making the drive stepwise movement in the form of paired pneumatic cylinders.

After heating, the part is fed to the pouring position, where the molten metal is poured into the casting mold 7 rotating from the actuator 17. At the extraction position, the overlapped part is removed from the mold by the pneumatic cylinder 37. When lifting, the washer 11 of the rod 9 turns the spring-loaded dog 38 around its axis, and hangs on them along the way. When the cutting table is rotated, the rod 9 slides over the copier 39, and the part from the extraction position to the preparation position of the molds is outside the mold. After the melting of one weld surface, the parts are returned to a repeated cycle for surfacing the opposite of the weld surface. The fully deposited part at the approach to the removal position by the deposited layer deflects the bar 41 and the flag 4 leaves the slot of the contactless switch 46, which gives a signal to the removal mechanism 47.

The presence of a weld layer signaling device mounted in front of the parts removal position allows the removable mechanism to be controlled and brought into operation only when the part is completely welded, which provides an increase in the productivity of the installation. At the signal of the deposited layer alarm device, the rod of the pneumatic cylinder 60 moves the carriage 49 up to the stop, the slide 51 fits the part 62 Further movement of the rod of the pneumatic cylinder 60 rotates the levers 52 to the vertical position, the slide 51 rises and removes the part from the rod 9, then the front part of the slipway rises, and the part on an inclined plane under its own weight slides onto a conveyor or into a storage container (not shown).
