Description

Изобретение относитс к термической обработке изделий при электроконтактном нагреве.The invention relates to the heat treatment of products with electrocontact heating.

Известна автоматическа установка дл электроконтактного нагрева иохлаждени изделий, содержаща механизм .загрузки, платформу с возможностью перемещени в вертикальной плоскости, кронштейны с контактными зажимами и бак с охлаждающей средой Ul.A known automatic installation for electrocontact heating and cooling of products, comprising a loading mechanism, a platform with a possibility of movement in a vertical plane, brackets with contact clips, and a tank with a cooling medium Ul.

Недостатком известной установки вл етс низка производительность, так как выгрузка заготовок занимает значительное врем в цикле обработки изделий.A disadvantage of the known installation is low productivity, since unloading blanks takes considerable time in the processing cycle of products.

Цель изобретени - повышение производительности за счет сокращенна времени на выгрузку изделий.The purpose of the invention is to increase productivity due to reduced time for unloading products.

Поставленна цель достигаетс тем, что она снабжена жестко установленной на платформе балкой, на которой размещены кронштейны с возможностью синхронного перемещени вдоль балки, и пружинс1ми, установленными между кронштейнами,The goal is achieved by the fact that it is equipped with a beam rigidly mounted on the platform, on which brackets are placed with the possibility of synchronous movement along the beam, and springs installed between the brackets,

На фиг. 1 схематично изображена предлагаема установка, общий вид; .на фиг. 2 - разрез А-А на фиг. 1.FIG. 1 schematically shows the proposed installation, the general view; .on FIG. 2 shows section A-A in FIG. one.

Установка состоит из станины 1, на которой установлены бункер 2, механизм 3 загрузки, подвижна платформа 4, ванна 5 дл охлаждени .The installation consists of a bed 1 on which a hopper 2, a loading mechanism 3, a movable platform 4, a cooling bath 5 are installed.

Внутри станины 1 размещены пневмоцилиндры 6 и 7, лоток 8 дл свободного сброса изделий 9 в тару 10, насос с баком 11, пневмостанци 12.Pneumatic cylinders 6 and 7, trays 8 for free discharge of products 9 into the container 10, pump with tank 11, pneumatic station 12 are placed inside the frame 1.

Подвижна платформа 4 перемещаетс горизонтально на роликах 13 и имеет на щеках 14 ролики 15, по кoтopы i вертикально перемещаютс ползуны 16. пневмоцилиндром 17, несущие контактные зажимы 18, которые закреплены на кронштейнах 19. Ползуны 16 соединены между собой балками 20, по которым сдвигаютс или раздвигаютс кронштейны 19 с помощью пневмоцилиндров 21 и возвратных пружин 22, которые выполн ют функции механизма раст жени и правки, а также механизма выгрузки, Контактные зажимы 1В имеют пневмоцилиндры 23 дл зажима изделий.The movable platform 4 moves horizontally on the rollers 13 and has rollers 15 on the cheeks 14, along which i sliders vertically move 16. pneumatic cylinder 17, carrying contact clamps 18, which are fixed on brackets 19. Slides 16 are interconnected by beams 20, which are moved or the brackets 19 are moved apart with the help of pneumatic cylinders 21 and return springs 22, which perform the functions of a stretching and straightening mechanism as well as an unloading mechanism. Contact terminals 1B have pneumatic cylinders 23 for clamping products.

Установка работает следующим образом .The installation works as follows.

Claims

To heat the heat treatment, the product 9 from the hopper 2 is supplied automatically by the acting loading mechanism 3 by means of the pneumatic cylinder 6 to the contact terminals 18. At the same time, the movable platform 4 is in the extreme left position. When the product 9 is fed to the contact terminals 18 by the pneumatic cylinders 21, the tein 19 bracket is shifted 1 | product 9 with pneumatic cylinders 23 is clamped in the contact glands. The product 9 is then lifted by the pneumatic cylinders 17. When the product 9 is lifted, the pneumatic cylinders 21 automatically deflect, with the result that the product 9 is put under tension by means of springs 22. At the same time, the loading mechanism 3 returns to the extreme left position to grip the next product. The movable platform 4 moves to the extreme right position, where power is automatically connected and heating occurs. When the product 9 reaches the set temperature and holds at this temperature for a predetermined time, the power is automatically turned off and the product 9 is lowered by means of the pneumatic cylinder 17 into the bath 5, where it is cooled. After cooling, the product is lifted by means of the pneumatic cylinder 17 and the plate on the platform 4 is moved to the extreme left position. During the movement of the PTF 4 under the tray 8, the pneumatic cylinders 23 are disconnected and due to the springs 22 the brackets 19 with contact clamps 18 are pushed apart. platform 4 is set to its original position for the next capture of the product. The cycle ends and automatically repeats in the same sequence. Expanding both contact clamps eliminates the unloading mechanism and combines it with the stretching and straightening mechanism, which ensures a free, focused discharge of products in a cycle without spending additional time on this operation, which, under other equal conditions, increases the productivity of the installation. Invention Automatic installation for electrocontact heating and cooling. The product includes a loading mechanism, a platform with the ability to move in a vertical plane, brackets with contact clips and a tank with a cooling medium, characterized in that, in order to increase productivity by reducing the time for unloading products, it is equipped with a beam fixed on the platform, where the drive brackets are placed with the possibility of synchronous movement along the beam axis, and the springs mounted on the beam between the brackets.
