Description

Изобретение относитс к оборудованию дл производства обуви, а более конкретно к машинам дл зат жки на колодке заготовки верха обуви.The invention relates to equipment for the production of footwear, and more specifically to machines for tightening on the shoe shoe top.

Известно устройство дл формовани A device for molding is known.

заготовки обуви перед зат жкой, содержащее механизмы клещей и носочного упора, установленные на вертикальной штанге,привод дл сообщени штанге перемещени в горизонтальном направлении и плиту, на которой установлены основани клешей fllshoe blanks before tightening, containing mechanisms for ticks and a toe rest, mounted on a vertical rod, a drive for telling the rod to move in a horizontal direction, and a plate on which the fll base is mounted

Недостатком известного устройства вл етс то, что оно обеспечивает лишь продольную и поперечную выт жку заготовки что недостаточно дл . получени хорошего качества формовани , образовани равномерной зат жной кромки.A disadvantage of the known device is that it provides only a longitudinal and transverse stretching of the workpiece, which is not enough for. obtaining a good quality of forming, forming a uniform tightening edge.

Цель изобретени - повышение качества формовани за счет сообщени клещам движени на след колодки дл огибани заготовкой грани следа и регулирование положени клещей по высоте.The purpose of the invention is to improve the quality of molding by telling the tongs to move onto the track of the block for bending the edge of the track by the blank and adjusting the position of the tongs in height.

Это достигаетс тем, что основани клещей установлены на плите свободно и соединены серьгами с носочным упором. This is achieved by the fact that the tick bases are set loosely on the slab and are connected by an earring to the toe rest.

, Кроме того, основани клещей снабжены винтами, опирающимис на плиту.In addition, the tick bases are provided with screws resting on the plate.

На фиг. 1 дана кинематическа схема устройства; на фиг. 2 - устройство, общий вид.FIG. 1 given the kinematic scheme of the device; in fig. 2 - the device, a general view.

Оно содержит механизм клещей, состо щих из двух пар губок, верхней 1 и нижней 2, и цилиндров 3, механизм носочного упора, редставп$пощего собой две призмы 4 и 5, вертикальную штангу 6 и силовой ципиндр 7 дл перемещени штанги в горизонтальном направлении.It contains a tick mechanism consisting of two pairs of sponges, upper 1 and lower 2, and cylinders 3, a toe stop mechanism, two prisms 4 and 5, a vertical rod 6 and a power tsipindra 7 for moving the rod in a horizontal direction.

Губки 1 и 2 шарнирно соединены одна с другой с помощью пальца 8, верхн губка св зана со штоком 9 цилиндра 3. Нижн губка 2 жестко соединена с цилиндром 3 и имеет поворотную стойку 10, надетую на стержень 11 основани клещей.The sponges 1 and 2 are pivotally connected to each other with the help of a finger 8, the upper sponge is connected to the rod 9 of the cylinder 3. The lower sponge 2 is rigidly connected to the cylinder 3 and has a rotary strut 10 worn on the rod 11 of the tongs.

Claims

The bases 11 of both pairs of tongs are freely mounted on a common plate 12 and are supported on it by screws 13 with caps 14 and lock nuts 15. Screws 16 are used to install the tongs parallel to the track line of the shoe. The plate 12 is rigidly connected to the rod of the power 11SH1Indra 17, which is embedded in the bushing 6. The prisms 4 and 5 of the toe rest are connected to one another with a screw 18 for adjusting to a certain shoe size and placed on the horizontal guide 19 of the rod 6. Prisms 4 and 5 connected to the base 11 with flares, earrings 2O. The springs 21, 22, 23 serve to return, respectively, the upper jaws 1 of the tongs, the plate 12 and the rod 6 to the initial position. The fitting 24 serves to install the right part of the pad. The operation of the device is carried out in the following manner. The block with the workpiece is placed next up to the fitting 24 and the prisms 4 and S. At the same time, with the help of screws 16 and 13, the tongs are positioned so that they are parallel to the contour of the pad track, and the blank is laid flat on the lower jaws 2 of the tongs. When the cylinders are activated, the 3 edges of the workpiece are clamped with pliers. Then the cylinder 7 moves the rod 6 with the mechanisms of the tongs and the toe stop in the direction of the front of the machine. The longitudinal stretching of the workpiece occurs. When the cylinder 17 is triggered, the plate 12 rises with the tick mechanism relative to the toe rest. In this case, the tick bases 11 with screws 13 make a combined motion due to the earrings 20 turning relative to the prisms 4 and 5. As a result, the flares move in a smooth curve, the radius of which is the earring 2O. Pliers with a workpiece bend around the edge of the track block, providing lateral stretching of the workpiece and covering the workpiece with a shoe. Forms a uniform tightening edge, which causes good quality of subsequent tightening operations. Claim 1. A device for shaping a shoe blank before tightening, comprising tick mechanisms and a toe stop mounted on a vertical rod, driven to communicate the rod moving horizontally and a plate on which the tick bases are installed, improving the quality of the molding, the base of the flares is set loosely on the plate and connected with earrings to the toe rest.

2. A device according to claim 1, characterized in that, in order to adjust the position of the ticks in height, their bases are provided with screws resting on the plate. Sources of information taken into account in the examination: 1. US Patent No. 3793661, cl. 12-14.5, 1974.
