SU1219211A1 - Carriage to apparatus for cutting-out blanks from flat stock - Google Patents

Description

The invention relates to the cold processing of materials by pressure and can be used to extrude blanks from a flat material.

The purpose of the invention is to increase reliability and simplify the design.

FIG. 1 shows a carriage to a device for cutting blanks from a flat material; in fig. 2 - the same, side view; in fig. 3 - plate section.

The carriage to the device for cutting blanks from a flat material contains a movable plate 1 with a bracket-holder 2. On the plate 1, fill the holes 3 for the passage of ejectors (not shown). A plate 5 is fixed on the back of the plate 1 by means of the holes 4. A plate 7 is hinged on the plate 1 on one side of the plate 5 by means of the axis 6, and on the other side of the plate 5 is similarly fixed on the plate 8 by means of the axis 9, and also on the plate 1 screws 10 and 11. The slats 7 and 8 are provided with longitudinal grooves 12 and 13, formed by collars, and with radially located grooves 14 and IS on them, made on the slats in the installation zone of the screws 10 and 11, respectively. x 6 and 9 are rotated relative to each other the sides are at a given angle on the divorce and fixed in the predetermined position by screws 10 and 1.1 at the expense of the slots 14 and 15, respectively. On the plate 1, between plates 7 and 8, plates are movably mounted relative to each other, each of the KOTOI Ks is made up of a set of tiles 16 (sections) with openings 17 for the passage of the ejectors. In each of the tiles 16 (sections) there are threaded holes 18 for fastening the cutting torches 19 /. At the ends of each of the tiles 16 (sections) there are blind holes 20 for accommodating the springs 21 expanding -. In each of

the current 16 is fixed guide rods 50 of the tiles 16 of the front plate, grommets 22, entering the holes 23, made in the adjacent tile 16. At the end of each guide rod 22, a groove 24 is made, which includes a screw 25, c. reverted to tile 16. On the side of the tiles 16, blind holes 26 are made for opening 27 of the springs 27.

The tiles of 16 plates are provided with blind holes 28, made in the center, in which rods 29 are fixed at one end and placed in slots

5 12 and 13 strips 7 and 8, respectively. The mechanism for moving the plates is made in the form of a bracket 30, which is mounted on the plate 1. The bracket 30 is provided with a sleeve 31, in which

plate 1 has a toothed rail 32 with a flange 33, and the bracket 30 is provided with a hole 34 in which shaft 35 is mounted. Gear 35 is fixed to shaft 35, which interacts with gear rack 32, and a lever 37 is attached that interlocks with the upper press plate (not shown). The cutters 19 outfill the blanks 38 from the flat material 39.

The carriage to the device for extruding blanks from a flat material works in the following way.

The carriage is in the initial position in the condition of waste discharge according to the position in FIG. 1 enters the cutting area. The lever 37 of the mechanism for moving the plates is rotated to the upper position under the action of the springs 27 of the plates of the tiles 16, while also under the action of the springs 21 the plates are moved apart, ensuring the expansion of the cutters 19 to discharge waste. The toothed rack 32 will move 3 5 to the extreme left position until the flange 33 is up against the sleeve 31. The cutters 19 on the plate 1 are set in the direction of the lower press (not shown). In this position, the carriage enters the cutting area. Initially, the upper press plate acts on the lever 37 and rotates it in a given direction to the level of the plate 1, and together with the lever 37 turns 5 rolls the shaft 35 and gear 36, which moves the rack 32 from the leftmost position to the rightmost position. When moving the rack and pinion 32, rests against one

moves the front plate towards the closure of all the plates, compressing the springs 21 and 27, and the plates of the tiles 16 are closed together, the edges of the cutters 19, while the rods 29 of the end plates 16 of the plates move on the shoulders 12 and 13 of the strips 7 and 8, ensuring retention on weight of tiles 16

together with the cutters 19. The next moment after the cutters are squeezed, material 39 is cut down. The cut pieces 36 enter the cutter cavities and the waste remains between them. When the upper press plate is lifted, under the action of decompression of the springs 21 and 27, the tiles 16 move apart between each other rt and move the toothed rack 32 from the rightmost position to the leftmost position, while the gear shaft 36 together with the shaft 35 and the lever

19211

37 rotates in the opposite direction. The opening of the cutters 19 is completed. The waste falls freely on the used area of material 5 39. The carriage with cut blanks enters the unloading zone (not shown), where the pin pushes out through holes 3 on plate 1 and through holes 17 on tiles 16, remove cut holes 19 from cutters blanks 36. After the total cycle is repeated.
