Description

The invention relates to devices for perforating cartographic materials with the aim of obtaining high accuracy of combining an image of a cartographic load and mechanizing the process of combining, in particular, in the manufacture of originals, negatives and slides, split masks, prefabricated; and positivov and printed forms, as well as the printing of colorful samples on offset machines and the circulation of cards on offset machines.

Perforation provides for P1) upholstery of register calibrated holes on cartographic materials (originals, engraving bases, phototechnical and other transparent films, aluminum and steel plates) with subsequent compulsory alignment of them in paints using special circuit and stationary driving pins, while stationary Driving pins are mounted on photo machines, offset machines and offset machines.

The perforator is intended for use in cartographic and topographic-geodesic production.

The purpose of the invention is to show the accuracy of image alignment on carving-graphic materials and the circulation of printed cards.

FIG. 1 shows the device, a general view; in fig. 2 - lever with handle; in fig. 3 - punched holoka; in fig. 4 - spring retainer; in fig. 5 - part of the device with limit stops.

The perforator consists of a working plate 1, made of wood and mounted on a metal frame (base), on which are located two guide rods and 3 connected to each other by rectangular conical wheels 4. Nine perforated pins are mounted on the guide rods and frame.

The HEAD, including the valve rod, has five heads 5, of which two extreme heads are for piercing oblong, and three middle ones - for round holes. Four identical heads 6 are mounted on the lateral direction with a knob to the rod, intended for punching only round holes (Fig. 1). On kla

Panna rod mounted lever 7 with a handle (figure 2).

The perforating head (Fig. 3) consists of a matrix 8, a core punch 9 with a punch and a set screw, spring-loaded machines 10 forcibly lifting the punch and a spring retainer 11. The spring retainer (Fig.4) is designed to firmly hold the perforated material during the punching period.

When lowering the wrench, the lock head is turned left or right, and when it is raised, it is set across the slot.

For forced lifting of core punches installed on the valve side, when punching holes on the originals and aluminum or steel plates, an additional fixture in the form of a hook bracket is provided. All nine perforating heads are equipped to shut them off. For exact alignment of any perforation material on the valve side there are adjustable stop-stops 12 valve spacing (Fig. 5),

For originals and films, the valve spacing is 25 mm; for printing plates of an offset press, 15 mm; for printing plates of offset presses, 8 mm;

In order to properly lay the film materials on the working plate and eliminate wrinkling, air bubbles and static electricity, the working plate is made of wood with evenly spaced through holes 13.

The perforator provides for identical punching of two, three or more register calibrated holes at the same time on all materials used in a closed technological cycle in preparation for the publication and publication of multicolor geographical maps.

The perforator is mounted on the valve and side sides at different distances, taking into account the formats of the cartographic materials used. The perforation is performed manually by turning the lever knob mounted on the valve rod.

In order to precisely align a set of negatives (transparencies), engraving bases, dissecting masks of prefabricated slides, etc., dismembered into paints, three calibrated holes are punched in the corners of the film at the same time, including one oblong and one eagle on the valve side, and on the side one round. The punching of holes on the films is carried out on one sheet or in packages of 3-4 sheets. In order to precisely align a set of printing forms, divided by colors, during the copying and making-up of forms on offset machines and offset machines, on aluminum and steel plates, two calibrated holes with 350 500 or 700 mm bases are punched simultaneously on the valve side, including one round and the other oblong. On originals, aluminum and steel plate plates, before perforation on the valve side, they are placed in the center with a pencil at risk. Then set the required valve size with adjustable stop-limiters. The material is placed on the working plate and brought to the stops, while the central risk of the material is combined with the central core punch, on which there is a risk and the inscription Center in red.

The perforator also allows punching of holes on materials with direct and mirror images of the pattern.

Claims (2)

1. A mapping perforator containing a working plate with two mutually perpendicular storbs, along one of which, being a valve, is mounted on a guide rod perforation heads, each of which consists of a die and a core punch, the punches have a round or oblong section, and a lever is mounted on the rod, characterized in that, in order to improve accuracy, along the second side of the plate, perforating heads, identical to the first, are placed on the guide rod, with both guide plates of cinemas Ceska coupled together, and two punches of each perforating head are extreme oblong sectional shape, and the rest - the round when all heads is provided with spring-Retentive ator. 2. A perforator according to claim 1, characterized in that, in order to increase the reliability of the fastening of materials on the plate, the latter is completed with evenly spaced through holes.
