Description

The invention relates to devices for the continuous cooling of parts such as pipes or glasses.

A machine for thermal processing of workpieces is known, in which a multisection chamber for cooling parts is used, including the chamber itself, a multi-tiered conveyor, an unloading mechanism, a water bath and a fan with an air duct [Ύ],

The disadvantages of such a camera are a large conveyor length, which is determined by the size of the cradles hinged along the height. In addition, the supporting sprockets are fixed to the cantilever, which limits the weight load per running meter of the conveyor chain. The hinged cradles in the process of moving have the ability to swing, which can lead to the fall of parts from the cradles. All this limits the operational capability of this cooling chamber, making it cumbersome and not suitable for shaking into small-sized straight-line production lines.

The prototype of the proposed solution can be a device for cooling parts, containing a chamber with

2

loading and unloading trays, inside of which a conveyor with carriers for parts is mounted, a fan with air duct 5 and a drive [2}.

The carrier is a baking sheet on which a pair of upper and a pair of lower rollers are installed, rolling in intermittent guides both on horizontal sections of the conveyor and on turning stars. Such an embodiment of the design eliminates the rocking of the carriers in the process of moving, and then, successfully, the loss of the product. However, the distance between the trays as in the previous chamber is significant, so the length of the conveyor is not reduced. In addition, as in the previous case, the presence of cantilever sprockets requires tightening of the frame of the conveyor apparatus, and, consequently, an increase in its metal intensity. The above disadvantages lead to a reduction in the usable area, a decrease in the reliability of the device.

The aim of the invention is to reduce the size and simplify the design, 30

FIG. 1 shows the device, a general view; in fig. 2 * - the same, a cross-section) in Fig.'3 - view along arrow B in FIG. one.

A device for continuous cooling of parts consists of a chamber 1, a framework consisting of welded from rolled products and ........ buried in cooled cooling shields. Inside

chambers 1 there is a conveyor, made in the form of successively located two elevators 2 of the shelf type, each of which represents closed parallel chains 3 located on sprockets 4 and connected between them sequentially arranged with a certain step by carriers of 5, made in the form of inclined comb-shaped shelves

“other than” on the Eh sides of the sockets. Asterisks 4 are set

: in pairs on the upper support

6 and the lower drive shaft 7, each elevator 2 in the upper part is provided with a rolling member restriction 8. The movement of the elevators 2 is carried out by the drive 9. The air heated by the parts is sucked through the duct 10 by means of the fan 11.

For convenience of operation, the device is equipped with loading trays 12 and unloading 13. The transfer of parts from one elevator to another is carried out using an overload tray 14 made inclined in the form of a double-sided comb.

Limiters rolling parts 8 are set to eliminate the possibility of "" dropping parts from comb-like "load 5 carriers because of the large run-up of cooled parts around the upper sprockets 4 and smoother rolling them and consist of a lever 15 and a stop 16 interacting with the free end of the latter.

Elevators 2. The parts from the loading tray 12 roll towards the Elevator 2, where they are individually picked up by the inclined comb shelves of the energy carrier 5 and move upwards. The fan 11 in combination with the air duct 10 creates a directional air flow, which, flowing around the heated parts, cools them and removes them from the cooling device.

In the extreme upper position, the part rolls along the descending branch of the closed parallel chain 3 of the elevator 2 up to the stop into the locking bar 18 of the parting limiter 8. At the same time, the next carrier 5 comes in contact with the roller 17, presses it and the lever 15 that contacts with the stop 16, together with the locking bar 18, they lift up with the free end upwards, freeing the cooled part, which continues the rolling interrupted by the bar 18. The lever 15 returns to its original position, and the part falls into the nest of the previous rocket carrier 3. It descends before meeting the overload tray 14 and is transferred to the next elevator 2. Further movement of the part occurs as described above. Cooled, the part rolls down the discharge chute 13 for further processing.

. Such an implementation of the proposed device for continuous cooling of cylindrical parts in the air flow can significantly reduce the length of the cooling conveyor, which significantly reduces the size of the device, and hence the production area. In addition, the absence of cantilever sprockets and intermittent guides simplifies the design, reduces the metal content, and improves the reliability of the device.
