Description

2. p. 1013087 Lini according to claim 1, which are flexible air-pressure hoses, we will establish that the base is made in the form of a vibrating-lifting table, curved around the perimeter.

The image is related to ligature production and concerns machines and equipment for mechanized conspiracy predominantly large-sized and complex configuration of rods of basic machine casting from cold-hardening, sand-resin or liquid-mobile mixtures for machine-tool construction. The famous line for the manufacture of hayotc-hardening mixtures, a coaxial mixer, a table of rotation of boxes with a countertop mounted table, a tilting table, a frame and transporting means ClvJ. 1500 kgb, since the line design allows the manufacture of rods from only a few hundred grams to 12O-15O kgf. Alteration of the line entails an increase in metal consumption, energy capacity, repair capacity and dimensions, and this causes the expansion of occupied production space. Rod manufacturing lines are also known, which include a vertically closed carriage conveyor for moving the core boxes, a continuous mixer, a compacted device; made in the form of a vibrator mounted on each trolley 2. The closest to the invention by technical essence and the result achieved is the line for the manufacture of rods, including the base, the vertically closed conveyor for moving the core boxes, the continuous mixer and the sealing device ts. However, these lines in workshops for the manufacture of basic machine casting using large-sized and complex-shaped rods from cold-hardening mixtures also do not provide an opportunity to mechanize the process of manufacturing rods, as the manufacturing process becomes more complicated, and there are imperfections in the rod configuration during production due to frequency collisions of the cart The conveyor guides (shaking foot defect) due to the constant contact between them and the supply of vibration during the compaction process, which slavlivaet impossibility of producing undercuts and the impossibility of making a large quality rods for injection. Nor is the process of solidification of the rod in a state of rest due to the constant impact of pulsating vibrations from vibrating at the sealing position of the carriage on the frame of the carriage conveyor. For these reasons, the line is unacceptable for the manufacture of large-sized complex configuration of rods for basic machine casting in the existing conditions. The aim of the invention is to expand the technological capabilities of the line in the manufacture of large-size casting cores of complex configuration. This goal is achieved by the fact that. in the line containing the base, the vertical of the sewed-closed carriage conveyor for moving the core boxes, the mixer of continuous operation and the fitting device, the latter is completed in the BHiie of the vibrating table with the supports entering between the conveyor rollers and installed under the bearing branch of the vertically closed conveyor belt in the form of flexible belts. The base is made in the vice of flexible air-pressure hoses installed along the perimeter of the vibrating-detachable table. FIG. 1 shows the proposed line, side view; in fig. 2 - the same plan view. The line consists of a vertically closed conveyor 1, on which the core box 2 is installed, and the mixer 3 is of continuous operation. The compaction means is made in the form of a vibration-lifting table 4 on the basis of 5. The vibration-lifting table 4 is equipped with

dttyMfl vibrators 6, mounted on the housing 7, and fixed in the upper part of the supports 8, which are in contact when lifting the table with the belt 9 of the conveyor 1 and the rod case 2, moreover. The supports 8 are inserted between the rollers 10.

The base 5 of the vibrating table 4 is made in the vice of the flexible air pressure hose 11 around the perimeter of the table 4, for example, a fire hose connected to the compressed air line .. The fire hose 11 is placed and fixed between the base 5 of the vibrating table 4 and the frame of the conveyor 12, Sealing the device is made in the vice of two vibrators located on both sides of the conveyor so that their unbalances rotate in opposite directions, providing a vertically directed force on the basket box 2, Means antovki, transport and transport of the rods from the rod crates are received conventional (known) for example, pavement elektrokran.

Lini works as follows. Mount the rod driver 2 onto the conveyor conveyor 1, the belt conveyor 1 and the engine 3 enter into care. When the rod terminal 2 approaches the discharge window of the mixer 3, the belt conveyor 1 stops, the vibroscope rises up from the conveyor rollers with rod rod, and the rod conveyor 1 rises, and the vibroscope rises from the rod rollers with a rod box and then the rod conveyor 1 rises, and the vibroscope rises above the conveyor rollers with rod rod which is stopped, the rod conveyor 1 rises, and the vibroscope rises from the rod rollers with a rod box and the rod belt goes up, the rod conveyor 1 stops, the vibroscope rises up from the conveyor rollers with rod rod, and the rod conveyor 1 rises, and the vibroscope rises from the rod rollers with a rod box, and the rod conveyor 1 rises; mixture. Then the vibration of the molding sand mixture in the core box is turned on. After compaction of the molding mixture is turned off, and the vibrating table is occupied

the initial position, In this position, the conveyor is turned on, moving the vrzhnevoe box to the curing position, and the next box takes the initial position, after which the cycle repeats. The core box with the hardened core is moved by an electric bridge crane to the area of turning, stretching, painting and further to the place of storage.

The main advantage of the proposed line is in expanding the technological possibilities of manufacturing large-sized complex configurations of rods by ensuring the ability at the compaction position to perform underneath, or any complexity of configuration, due to the exclusion of the O box collider: conveyor rolls.

The curing process is also improved due to the elimination of vibration from the vibrating core box at the sealing position.

In addition, the design allows the use of vehicles for mechanical transmissions - the accumulation and transportation of the drawers to the filling and compaction position and the further transfer and accumulation at the curing site and further to the final processing and storing of the sterms.

V

This provides a significant reduction in the manufacture of Sri rods while simultaneously reducing the metal consumption, energy consumption and repair capacity from the line, reducing the occupied area of the core.
