Description

Изобретение относитс к области автоматизации и механизации процессов обработки металлов давлением и может быть использовано дл поштучной подачи заготовок в нагревательные устройства.The invention relates to the field of automation and mechanization of metal forming processes and can be used for single-piece supply of blanks to heating devices.

Известно устройство дл ориентации -и выдачи заготовок, содержащее бункер с выходным отверстием, ограниченным дном, неподвижными и под вижной , св занной с приводом, стенками , и шибер Clj.A device for orienting and dispensing blanks is known, comprising a hopper with an outlet opening, a bounded bottom, fixed and under a sliding one, connected with an actuator, walls, and a gate Clj.

Недостатком известного устройства вл етс низка надежность работы устройства ввиду возможного заклинивани подвижной стенки при выда- че деталей из бункера.A disadvantage of the known device is the low reliability of the device due to the possible seizure of the moving wall when dispensing parts from the hopper.

Целью изобретени вл етс повышение надежности выдачи заготовок.The aim of the invention is to improve the reliability of the issuance of blanks.

Поставленна цель достигаетс тем, что в устройстве,содержащем бункер с выходным отверстием, ограниченным дном, неподвижными и подвижной, св занной с приводом, стенками, и шибер,стенка бункера, обращенна к шиберу, установлена неподвижно в вертикальной плоскости, подвижна стенка выполнена в виде части поверхности дна бункера, со стороны шибе- ра, а на шибере установлен упор.The goal is achieved by the fact that in a device containing a bunker with an outlet opening, bounded bottom, stationary and movable, connected to a drive, walls, and a gate, the wall of the bunker facing the gate is fixed in a vertical plane, the movable wall is in the form part of the surface of the bunker bottom, on the side of the gate, and the stop is mounted on the gate.

На фиг.1 изображено устройство, общий вид; на фиг. 2 - то же, при :размещенном в верхнем положении шибере .Figure 1 shows the device, a general view; in fig. 2 - the same, with: placed in the upper position of the gate.

Устройство дл ориентации и псаитучной чыдачи заготовок содержит бункер 1 с наклонным днищем, раз 10 деленный вертикальной жестко закрепленной перегородкой 2, зазор между нижней торцевой поверхностью которой и поверхностью днища равен рассто нию между передней стен15 кой 3 бункера и перегородкой 2 и составл ет 1,2-1,25 диаметра заготовки . С боковых сторон бункер ограничен направл ющими 4, одна из которых имеет возможность перемеще20 ни и позвол ет регулировать ширину бункера в зависимости от длины размещенных в нем заготовок.The device for orientation and psiatach of the blanks contains a hopper 1 with an inclined bottom, 10 times divided by a vertical rigidly fixed partition 2, the gap between the lower end surface of which and the bottom surface is equal to the distance between the front wall 15 of the bunker and the partition 2 and is 1.2 -1.25 diameter of the workpiece. On the sides, the bunker is limited by guides 4, one of which is movable and allows the width of the bunker to be adjusted depending on the length of the blanks placed in it.

Шибер 5 выполнен приводным и имеет возможность вертикального пере25 мещени в пространстве между передней стенкой бункера и перегородкой, при этом толщина шибера должна составл ть диаметр заготовки. На шибере в нижней его части закреплен The gateway 5 is designed to be driven and has the possibility of vertical displacement in the space between the front wall of the bunker and the partition, and the thickness of the gate should be the diameter of the workpiece. On the gate in its lower part is fixed

Claims

30 stop 6. The bottom of the hopper is made with a movable part, a hinged wall 7, the length of which is equal to 3-4 diameters of the workpiece. On the left side of the gate 5, the ejector 8 of the accumulator 9 is rigidly mounted. Under the bunker's bottom there is a hinged-lever system consisting of a double-arm lever 10 hinged on the support 11, 12 and pneumatic vibrator 13. The device works as follows. The blanks loaded into the hopper roll through the slot into the upper cut of the gate 5 when the latter is in its lower initial position. When the vane drive is turned on, the pneumatic vibrator 13 begins to work, which periodically presses the right end of the lever 10 at a given frequency, with the left end of the lever through the pull 12 lifts the stack 7. Under the return stroke of the vibrator 13, the wall 7 lowers and the same way the shaking of the blanks takes place, contributing to the destruction of the set of blanks. Then, depending on the set feed cycle, the pneumatic cylinder of the drive of the gate 5 is activated and, together with the workpiece, the gate begins to move vertically to the upper position. When the gate at the upper end position is reached, the workpiece rolls into the drive 9, and from the accumulator by the ejector 8 is fed to the guide tray. Simultaneously, the stop 6, mounted on the gate 5, lifts the wall 7, carried out the mutual movement of the blanks and the destruction of the arch. Due to the presence of a wall installed vertically in the bunker and with a certain gap between its lower end surface and the bottom surface, a cyclic piece of workpieces is fed into the hopper and then processed. An apparatus for orientation and piecewise dispensing of cylindrical blanks, comprising a hopper with an outlet opening, a limited bottom, fixed and movable, associated with a drive, walls, and a gate, characterized in that in order to improve the reliability of dispensing blanks, the wall of the hopper, facing the gate, fixed in a vertical plane, the movable wall is made as part of the surface of the bunker bottom, on the side of the gate, and the stop is installed, which interacts with the movable wall.
