Description

Изобретение относитс к области механизации и автоматизации обработки металлов давлением и может быть использовано при подаче штучных заготовок в зону обработки.The invention relates to the field of mechanization and automation of metal forming and can be used when feeding piece blanks to the treatment area.

йзвестено устройство дл подачи штучных заготовок, содержащее верхнюю и нижнюю плиты штампа, магазин дл заготовок, толкатель, св занный с верхней плитой штампа Cl.A device for feeding piece blanks containing an upper and a lower die plate, a blank magazine, a pusher connected to the upper die plate Cl.

Наличие в известном устройстве системы рычагов, необходимых дл передачи движени толкателю, усложн ет конструкцию устройства.The presence in the known device of a system of levers necessary for transmitting motion to the pusher complicates the design of the device.

Целью изобретени вл етс упрощение конструкции устройства.The aim of the invention is to simplify the design of the device.

Поставленна цель достигаетс i тем, что в устройстве, содержащем верхнюю и нижнюю плиты штампа, магазин дл заготовок, толкатель, св занный с верхней плитой штампа, толкатель выполнен в виде гибкого органа , жестко закрепленного одним конце на верхней плите штампа и свободным концом имеющего возможность од . ностороннего изгиба в направлении подачи заготовок, при этом устройство снабжено направл ющим средством дл толкател .The goal is achieved by the fact that, in a device comprising an upper and lower die plates, a blank magazine, a plunger connected to the upper die plate, the plunger is made in the form of a flexible organ rigidly fixed at one end on the upper die plate and having a free end having one side bending in the feed direction of the blanks, the device being provided with a guide means for the pusher.

Гибкий орган состоит из последовательно св занных между собой отдельных звеньев, образующих цепь с односторонним изгибом.A flexible organ consists of successively interconnected individual links forming a chain with a unilateral bend.

Направл ющее средство выполнено в виде , размещенных по обе стороны.толкател .The guide means is made in the form placed on both sides of the pusher.

На фиг. 1 изображен общий вид устройства; на фиг.2 - узел I на FIG. 1 shows a general view of the device; figure 2 - node I on

10 фиг.1; на фиг. 3 - вид А на фиг.2.10 figure 1; in fig. 3 is a view A in FIG.

Устройство дл подачи штучных заготовок в зону обработки содержит толкатель , выполненный в виде цепи 1, The device for feeding the piece blanks into the processing zone contains a pusher made in the form of chain 1,

Claims

15 fixed with the possibility of adjusting movement on the top plate 2 of the stamp. To ensure the movement of the chain 1 along a predetermined path along its two, guide rollers 3 are placed, having the possibility of rotation on the axes in the figures are not marked with a position) attached to the lower plate 4 of the stamp. The device also has an inclined tray 5, which has a side facing the top plate 2 of the die, a groove 6 for entering the chain 1, and at the bottom a horizontal section necessary for stopping the workpiece 7 in the process of delivery. In the upper part of the tray 5 is placed the mechanism 8 for single-piece delivery of blanks. Chain 1 consists of individual links 9, interconnected by means of axes 10, while the protrusion of one link enters the groove of another link. on. In order to provide one-sided, bend of chain 1, its links 9 have cylindrical surfaces 11. The device operates as follows. When the stamping plate 2 is placed in the upper position, the chain 1 is in a vertical position and is outside the tray 5. The mechanism 8 for the single delivery of blanks provides for the issuance of a single blank that rolls down along the tray 5 and stops in its lower horizontal section. When moving the top plate 2 of the punch down the chain 1, which is supported by means of rollers 3, enters the groove of the tray 5 and slides along its inner surface, advances the workpiece 7 into the treatment zones, pushing the previous workpiece out of it. During the processing of the workpiece, further movement of the upper plate 2 of the stamp occurs, while chain 1 acquires an additional bend in its free area. The device allows for a reliable supply of heated blanks to the treatment area, regardless of their shape. Claim 1. Device for supplying piece blanks to a treatment zone containing upper and lower punch plates for blanks, a pusher connected to the upper punch plate, characterized in that, in order to simplify the design, the pusher is made in the form of a flexible organ, rigidly fixed at one end on the top plate of the stamp and with the free end of one-sided bending in the feed direction of the blanks, the device being provided with a guide means for the pusher.

2. The device according to claim 1, wherein the flexible body consists of successively interconnected individual links forming a chain with a one-sided bend.

3. A device according to claim 1, characterized in that the guide means is embodied in the form of rollers arranged on both sides of the pusher.
