Description

one

The invention relates to devices for quenching articles, preferably of low mass, and can be used in mechanical engineering.

Semiautomatic machines for quenching, tempering and isothermal processing of low-mass parts are known, including salt baths for heating for quenching or tempering and mechanisms for moving the suspensions consisting of chain conveyors or conveying chains with a pitch conveyor and a hydraulic drive Ci3 and 23.

Due to the relatively low speed of movement of products with the help of chain drives in such installations, parts are being harvested in air; In addition, cooling them with a cage in pendants or baskets leads to a mottled hardness due to the high density of the articles being processed.

A semiautomatic device for heat treatment is also known, which contains a mechanism for moving parts and technological baths with receptacles with hydraulic port

The specified semi-CXT excludes air-borne parts when the suspension is moved by an auto-operator. However, this semiautomatic device does not provide high-quality quenching due to the cooling of machined parts with a charge in the suspension. The cooling solution only smears the parts located on the surface of the cage, which does not penetrate into it.

The aim of the invention is to improve the quality of heat treatment.

The goal is achieved by the fact that the semiautomatic device is equipped with copiers mounted on the baths and a mechanism, which is connected with the mechanism for moving the crocks and the hinged hinge in them that interacts with the copiers during lowering.

FIG. 1 shows ripivuiajaeMUu semiautomatic; on fi1 2 - that jo, pa: 5pi 3 aa in fig. one; in fig. 3 - yni -.- i 1 ira of FIG. 1. The semiautomatic device contains a bath 1 for heating for quenching, a bath 2 for cooling, and a mechanism 3 for moving the cage. To unload the tanks, they serve as a basket 4, which is connected to the mechanism 3 and which are moved by means of the brackets 5 fixed in the supports, and copiers 6, which are rigidly connected to the cooling baths 2. In the cooling baths 2 there are receptacles 7 which are connected in a drive 8 of the reciprocating movement. The semiautomatic device works in a skinny manner. Small parts are poured into a swinging basket 4, which is connected with the help of the brackets 5 fixed in the supports with the mechanism 3 for moving the load. The mechanism for moving the cage from the initial position transfers the cage to the bath 1 for heating under quenching, and the cage in basket 4 is fed in this bath. After the technologically necessary time has elapsed, the movement mechanism 3 pulls out the swinging basket 4 with heated parts and transfers it to one or another tal and uepcnw - 1 VV- - cooling bath 2 (according to the technical specifications At the moment of lowering in the vertical plane, basket 4 contacts the by copiers 6, slides over them, overturns the cage pours into the receiving tank 7 of the cooling bath 2. The cage mechanism 3 returns to its original position. Depending on the technological need, the hardened parts immediately or after carrying Already cycles are poured out of the cooling bath 2 when the reciprocating movement drive 8 is in. The unloading mechanisms with a basket and copiers, as well as the receptacles in the reciprocating cooling baths, create favorable conditions for uniform cooling of the decals low mass to reduce the cooling time compared to the cooling of such parts with the charge (in a basket or other device) and thereby significantly improve the quality of heat treatment of small parts. Claims of the Invention A semi-automatic machine for parts, containing a mechanism for moving parts and technological baths with drive receptacles, is also distinguished by the fact that, in order to improve the quality of heat treatment, it is equipped with copiers installed on Bamiax and an unloading mechanism made in the form of brackets and pivotally hardened „„ in a mix basket, interacting with co-peers at the moment of lowering.
