Description

The invention relates to the manufacture of "products from polymeric materials and can be. used in shoe factories for cutting parts of shoes.

A device for cutting products from sheet material is known, comprising a pivotal ⁵ vertical support bearing carrier plates with cutting torches interacting with the upper press plate located at its upper and lower ends, and ejector plates mounted inside the support the action of its own weight on the guide bearings and provided with spring-loaded with respect to the support clamps and mechanisms for moving the clamps. ₍₅ The mechanisms for moving the latches are made in the form of electromagnetic coils, the cores of which are connected with the latches 11].

A disadvantage of the known device is the complexity of its design, due to the presence on the rotary support of a number of electromagnetic coils, as well as the inability to ensure reliable ejection of finished products with continuous movement of the slide

press, as when turning the support possible bias on the guide plates with ejector.

The aim of the invention is to simplify the device and ensure reliable ejection of finished products.

To this end, each of the mechanisms for moving the latches is made as mounted on a plate with ejectors with the possibility of interaction with the upper plate of the press at the lower position of the plate of the rod, which is spring-loaded relative to this plate and carrying the stop interacting with the retainer.

FIG. 1 shows the device, a general view; in fig. 2 - plates with ejector and mechanisms for moving the clamps of these plates.

The device for cutting out articles from sheet material comprises a support 1 pivoting in a vertical plane, carrying the plates 2 located at its upper and lower ends.

On the plates 2 mounted cutters 3, interacting with the upper plate 4 of the press.

Inside the support 1 on the guides 5 mount ™ '~ baths of the plate 6 with ejectors 7. Plates 6

provided with clamps 8, and mechanisms for moving clamps. Each of the mechanisms for moving the latches is designed as ₅

mounted on one of pyit 6 rods 9, spring-loaded this plate with a spring 10 and provided with a stop 11. At the ends of the rods, interacting with the upper plate 4 of the press, the adjusting stops 12 are installed.

The device works as follows. Adjusting stops 12 souring them in the right direction on the rods 9 are set to a predetermined height so that when the lower position of the upper press plate is positioned, it will con- ₅ with the ends of the stops 12, and plate 6,

d; carrier rods with these stops, was in the lowest position.

. The first cutting of products by the cutters 3 of the upper and lower plates 2 is carried out alternately ₂ but with a discontinuous movement of the press ram and the unloader drive disconnected (not shown). At this time, the automatic installation of the ejector 7 for the ejection of products and waste. When "supporting" 25 the ejector of the slab, which is currently in its lowest position, is lowered under the action of its own weight, one is lowered to the surface of the cut-out from _:

.... ·: Delia, others, go through the holes located ₃₀ 'between the cutters, lower below,

as the waste is removed immediately after the cutting - ki Fixation ejectors in the working position by retaining plates 13, then include the loader drive zatru- · ₃₅ zhayut cutters for sheet material 3 plates 2 located at the upper end of the support T, 'and produce cutting workpieces. When moving the upper plate 4 of the press down, it interacts with the adjusting stops 12 of the rods 9. The rods 9 are lowered, compressing the springs 10, and the stops interact with the stop 14 of the clamps 8 and retract the latter from

plates 6 · Plates 6 together with the ejector 7 under the action of their own weight and pressure of the rods 9 fall and push the products cut out for the previous press stroke and located on the cutters currently placed at the bottom end of the support 1. The products are placed on the receiving table 15. When Moving the upper plate 4 of the press upward, the support 1 rotates around the horizontal axis 16 by 180 °. The cutters 3, from which the blanks are extracted, are on the upper end of the support, and the cutters with cut blanks are on the lower end. Then the operations are repeated in the described sequence.
