(54) УСТРОЙСТВО ДЛЯ ЗАГРУЗКИ КАМЕРНОЙ ПЕЧИ(54) DEVICE TO DOWNLOAD A CHAMBER FURNACE

II

Изобретение относитс к механизации процессов термообработки, а именно к загрузке заготовок в камерные нагревательные печи.The invention relates to the mechanization of heat treatment processes, in particular to the loading of blanks into chamber heating furnaces.

Известно устройство дл загрузки нагревательной печи, содержащее установленные на раме каретку с лотком и св занный с ней привод возвратно-поступательного перемещени . Каретка снабжена толкателем с ограничительной линейной, лотокштангами с роликовыми хвостовиками, а рама - копирными планками, установленными с возможностью контакта с хвостовиками 1.A device for loading a heating furnace is known, comprising a carriage with a tray mounted on a frame and a reciprocating movement associated with it. The carriage is equipped with a pusher with a restrictive linear, trays with roller shafts, and the frame - with copy rods installed with the possibility of contact with the shanks 1.

Однако устройство характеризуетс подачей заготовки только в определенное место и малой производительностью за счет пощтучной загрузки.However, the device is characterized by feeding the workpiece only to a certain place and low productivity due to a piece-load.

Известно бункерное дозирующее устройство , содержащее раму, на которой расположены бункер, механизм выдачи заготовок из бункера и задающее устройство 2.Known bunker metering device containing the frame on which the bunker, the mechanism for issuing blanks from the hopper and specifies the device 2.

Недостатком данного устройства вл етс неполное использование полощади пода.The disadvantage of this device is the incomplete use of the footwell.

Цель изобретени - более полное использование площади пода печи.The purpose of the invention is to more fully utilize the area under the furnace.

Поставленна цель достигаетс тем, что устройство снабжено дополнительной рамой, выполненной с возможностью поворота, при этом задающее устройство выполнено в виде рольгангов, один из которых укреплен стационарно на дополнительной раме.The goal is achieved by the fact that the device is equipped with an additional frame made with the possibility of rotation, while the setting device is made in the form of roller tables, one of which is permanently fixed on the additional frame.

5 другой - с возможностью перемещени относительно этой рамы и имеет на переднем конце подпружиненный щиток, а днище бункера имеет привод перемещени в вертикальном направлении.5, the other is movable relative to this frame and has a spring-loaded shield at the front end, and the bottom of the hopper is driven to move in the vertical direction.

JQ На фиг. 1 схематически показана профильна проекци установки дл загрузки камерной печи; на фиг. 2 - один из вариантов установки у печи, вид в плане; на фиг. 3 - разрез /f-А на фиг. 2.JQ FIG. Figure 1 shows schematically a profile projection of an installation for loading a chamber furnace; in fig. 2 - one of the options for the installation of the furnace, view in plan; in fig. 3 shows a section / f-A in FIG. 2

Предлагаема установка состоит изThe proposed installation consists of

Claims

15 of the column 1 with a movable frame 2 located thereon, which is connected to the column 1 by a 3 turn actuator. A hopper 4 is installed on the movable frame 2 with a mezzanism of changes in its volume installed in it, in the form of a movable bottom 5, moved by a pneumatic cylinder 6. On the bottom 5 there is a pneumatic cylinder 7 with a pusher 8 mounted on its end. On a movable 38 frame 2 a stationary roller table 9 is installed with a master device located under it in the form of a mobile roller table 10 mounted on rollers 11 and a movement drive 12. At the end of the mobile roller table 10, a spring-loaded flap 13 is mounted. The entire device is mounted on the frame 15. The installation works in the following way. The hopper 4 is loaded with rollover from the workshop tare .; The pneumatic cylinder b lifts the bottom 5 with workpieces at low speed, and the pneumatic cylinder 7 with a much higher speed and frequency using the pusher 8 pushes the workpiece onto the canvas of the stationary inclined roller table 9. The workpiece, moving under its own weight, rolls along the roller table 9, gathering speed, and falls on the canvas of the mobile roller table 10, from where it is, slowed down by a separate flap 14, falls on the furnace. To change the location of the part supply, the actuator 12 moves the movable roller table 10 to the desired position, and the rotary actuator 3 changes the angular position of the movable roller table 10. The change in the final speed of the workpiece is determined by adjusting the spring stop 13. The proposed installation reduces the hearth wear and extends its life. operating at 15-20 / o, and 04 more fully used under the furnace. This increases the productivity of the furnace by 20%. The economic effect from the use of the proposed installation is 17.1 thousand rubles. The invention The device for loading the chamber furnace, containing the frame on which the bunker is located, is mechanized from the bunker and setting the device, characterized in that, in order to fully utilize the area of the wire, it is equipped with an additional frame adapted to rotation, while the master device is made in the form of roller tables, one of which is permanently fixed on an additional frame, the other is movable. relative to this frame, and has a spring-loaded shield at the front end, and the bottom of the jaw has a movement drive in the vertical direction.
