Description

The utility model relates to auxiliary devices for chemical-thermal processing of parts and can be used to prepare spray gun bodies for carburizing.

In mechanical engineering, solid carburizing carburizing is widely used to harden the surfaces of steel parts. In order to achieve the desired surface grout, the solid carburizer should be placed as evenly as possible close to the surface of the part.

A device is known in the form of a special container made of refractory steel, in which parts intended for carburizing are placed in layers, and a solid carburizer, and the thickness of the layers is strictly limited (URL: / https://martensit.ru/ximicheskaya/cementaciya/; date of access 20.07.2020).

The disadvantages of the known solution include increased labor intensity when extracting parts from the mold after carburizing and separating them from the carburizer. In addition, an important drawback is the uneven supply of the carburizer to the surfaces of the parts, especially in cases where the parts have internal cavities. This problem is relevant, in particular, for nozzle bodies with small, in diameter, central holes, the surfaces of which must be carburized (cemented).

The closest in terms of the set of essential features - the prototype of the claimed utility model - is a machine for filling cavities of products with bulk material, including a frame made in the form of a welded frame structure, and a vibrating chute installed above it, providing for the supply of bulk material, its distribution among products and removal of surplus bulk material (AS No. 280515, publ. 03.09.1970. Bull. No. 28). According to the well-known solution, the products, the cavities in which it is necessary to fill with bulk material, are the bodies of the nozzles of the nozzles, and the bulk material is a solid carburizer. The nozzle bodies are installed on the vibrating tray guides in multi-position technological containers. The supply and distribution of the solid carburizer is carried out using a built-in device in the form of a rotating loading drum with a horizontal axis of rotation and blades located inside it at different angles to the axis of rotation. The loading drum is driven by an electric motor, and the drive includes a gearbox, a chain drive, a belt drive, an intermediate shaft rotating in bearings, and gears. The vibrating chute is installed inside the loading drum on spring dampers and is driven by an electromagnet. Removal of surplus solid carburizing agent is carried out using elastic blades sweeping the upper ends of the nozzle bodies. There is also a blowing of the nozzle bodies with air constantly supplied through the air duct from the network.

The disadvantages of the known solution include:

- the complexity of the design, due to the presence of a rotating loading drum and its drive,

- danger of electric shock to the operator due to the electric drive of the loading drum,

- increased noise level, the source of which is a vibrating channel, a rotating loading drum, air blowing over the nozzle bodies after they are filled with a solid carburizer,

- constant air consumption from the network.

The technical problem to be solved by the proposed utility model is to eliminate the shortcomings of the prototype: to create a simple and efficient installation for filling the nozzle bodies with a solid carburizer without the danger of electric shock, which creates a lower noise level.

The task is solved by:

- replacement of the electromagnetic drive with a pneumatic drive,

- replacement of a rotating loading drum with its drive by manual loading of a solid carburizer,

- replacement of elastic blades and the system for blowing compressed air into the nozzle bodies by manually removing excess solid carburizer.

A novelty in the proposed installation for filling product cavities with a solid carburizer is the combined use of:

- pneumatic drive vibrating tray;

- manual loading of solid carburizer and removal of its excess after filling the cavities of the products.

An installation proposed as a utility model for filling nozzle bodies with a solid carburizer is shown in FIG. 1. The installation for filling the nozzle bodies with a solid carburizer includes a frame 1 made in the form of a welded frame structure and a vibrating channel 2 mounted on the upper part of the frame 1 and driven by a vibrator 4. The vibrating channel 2 has a conical pan 21 for collecting surplus solid carburizer and a sleeve 22 for the targeted removal of the said surplus from the proposed installation. The vibrator 4 has a pneumatic drive and includes fittings 41 and 42 for supplying and removing air from a pressure source (not shown in the figure). It is preferable to supply air to the vibrator 4 from the factory network.

FIG. 1 shows the proposed installation with a technological container 3 installed on a vibrating tray 2 with nozzle bodies 5.

The design of the vibrator is not subject to protection under this application.

The technological container 3 is made in the form of a welded structure of steel parts in such a way that after installing the bodies of the sprayers 5 between the bodies and parts of the technological container 3, gaps sufficient for the passage of excess solid carburizer under the action of gravity are maintained.

Installation for filling the bodies of nozzles with a solid carburizer works as follows.

Technological container 3 is installed on a vibrating tray 2. Nozzle bodies 5, to be filled with a solid carburizer, are installed in a technological container 3. Air is supplied to the vibrator 4. A solid carburizer (not shown in the figure) is poured manually onto the ends of the nozzle bodies 5. Excess solid carburizer is removed manually, and the removed excess solid carburizing agent is poured through the gaps in the technological container 3 into the conical pallet 21 of the vibrating tray 2 and further along the sleeve 22 are removed from the installation.

The technical result of the proposed utility model is to exclude the possibility of injury to the installation operator by electric current, as well as to reduce the noise level due to the exclusion from the design of the electric motor and the drive, transmitting rotation from it to the installation parts.

The proposed design of the installation for filling the nozzle bodies with a solid carburizer was introduced into the serial production of fuel injector nozzles at the Altai Precision Products Plant.
