Изобретение относитс к обработке металлов давлением и может быть использовано при установке и сн тии штампов со стола пресса.The invention relates to the processing of metals by pressure and can be used when installing and removing dies from the press table.

Известно устройстводл установки и сн ти штампов, содержащее размещенные на станине откидные рольганги а также гибкий элемент, взаимодействующий с приводным механизмом и штампом 1 .A device for mounting and removing dies is known, which comprises folding folding tables placed on the frame as well as a flexible element that interacts with the drive mechanism and dies 1.

Недостатки данного устройства -. наличие сменных скалок, воспринимающих изгибающий момент от гибкого элемента, и больша трудоемкость при подготовке устройства к работе из-за необходимости укреплени скалок , стаканов и гибкого элемента.Disadvantages of this device -. the presence of interchangeable skalok, perceiving the bending moment from the flexible element, and great complexity in the preparation of the device to work because of the need to strengthen the skalok, glasses and flexible element.

Цель изобретени - повышение производительности и удобства обслуживани .The purpose of the invention is to increase productivity and serviceability.

Указанна цель достигаетс тем, что устройство .дл установки и сн ти штампов, содержащее размещенные на станине откидные рольганги, а faKже гибкий элемент, взаимодействующий с приводным механизмом и штампом , снабжено установленньми на станине пресса с возможностью -поворота двум откидными кронштейнами с огибакхцими ролика№1и на конце, взаимодействующими с гибким элементом, а также закрепленными на гибком элементе двум фиксаторами, взаимодействующими со штампом.This goal is achieved by the fact that the device for installing and removing dies, containing folding roller tables placed on the frame, and faX, a flexible element that interacts with the drive mechanism and the stamp, is fitted with a twist on the frame of the press with two folding brackets with roller ogibakhs. 1 and at the end, interacting with the flexible element, and also fixed on the flexible element by two clamps, interacting with the stamp.

На .фиг. 1 изображено устройство, общий вид; на фиг. 2 - то же, вид сверху.On .fig. 1 shows the device, a general view; in fig. 2 - the same, top view.

Устройство дл установки и сн ти штампов содержит гидроцилиндр 1 соA device for mounting and removing dies comprises a hydraulic cylinder 1 with

o штоками, установленный на станине 2 пресса, на штоках которого смонтированы блоки 3. На станине 2 пресса установлены блоки 4, откидные кронштейны 5 с огибающими роликс1ми 6 и блоки 7. БЛОКИ 3 и 4 и огибающие ро5 лики 6 св заны посредством гибкого элемента (троса) 8 через упорные ролики 9 и 10, установленные на верхней и -нижней ветви гибкого элемента 8, причем длина гибкого элемента o rods mounted on the base 2 of the press, on the rods of which the blocks 3 are mounted. On the base 2 of the press there are blocks 4, folding brackets 5 with roll envelopes 6 and blocks 7. BLOCKS 3 and 4 and curvature 6 are connected by means of a flexible element ( cable) 8 through the thrust rollers 9 and 10, mounted on the upper and lower branches of the flexible element 8, and the length of the flexible element

0 определ етс и устанавливаетс при монтаже и не измен етс при экстпуатации . На нижней ветви гибкого элемента 8 смонтирован фиксатор 11. Управление работой гидроцилинлра 0 is determined and set during installation and does not change upon extrusion. A retainer 11 is mounted on the lower branch of the flexible element 8. Operation of the hydrocyline

Claims

5 carries an electric valve 12 / connecting cavities a and b of the hydraulic cylinder 1 with high pressure pipelines 13 and drainage pipes 14. The folding brackets 15 are mounted on the side of the folding brackets 15, onto which a stamp 16 is placed. The device is operated the following time: The folding brackets 5 with the enveloping rollers b are lowered to the horizontal position, the working fluid is supplied from pipeline 13 high; the cavity a of the hydraulic cylinder 1, wherein the cavity of the hydraulic cylinder b is connected by means of the valves 12 with the drain 14, the latch 11 moves in the direction of the folding brackets 5, On. the folding-slingo 15 installs the die 16, attaches it to the lower branch of the flexible element 8 with retainers 11. The working fluid is supplied from the high pressure pipe 13 to the floor of the hydraulic cylinder 1 through the electric valve 12, and the cavity of the hydraulic cylinder 1 is connected to the drain 14. Under the action of the working fluid, the latches 11 with the die 16 are moved to the press zone to the :: extreme position. Folding brackets 5 raise in a vertical position. The stamp setting operation is complete. The removal of the stamp from the press table is carried out as follows. The folding brackets 5 are lowered to a horizontal position, the working fluid from the pipeline 13 passes through the valve 12 to the floor of the hydraulic cylinder 1, and the fluid from the cavity b flows through the pipeline 14 to the drain, the latches 11 from the straps 16 are moved from the press zone to the folding roller tables 15. The use of blocks 3 and 4, forming a polyspast, allows to increase the course of the rolling out of the slide with a small stroke of the hydraulic cylinder rod 1. The use of a device for installing and removing dies improves the productivity of the press tool. Hovhan by reducing the downtime and labor prepare the device for operation, reliability of operation due to lack of replaceable elements, and serviceability. An apparatus for mounting and removing dies, comprising folding bed conveyors arranged on a frame, as well as a flexible element that interacts with a drive mechanism and a die, characterized in that 4TOj, in order to increase productivity and ease of operation, it is equipped with turning with two folding brackets with envelopes of rollers at the end, interacting with the flexible element, as well as with two pins fixed to the bending element.
