Description

A manual device for perforation relates to the printing industry, and specifically to post-printing equipment.

In the printing equipment of the printing industry there is no device that provides perforation of stationery products in single copies.

The well-known automatic bench numbering and punching machine Pierce SocBox SN Micromatic 4000 is designed to work with average volumes of circulations of manufactured products. Friction feed for accurate handling of single sheets and sheet blocks, an automatic lubrication system, the ability to connect additional scoring and perforation modules expand the functional range of the machine's abilities and increase productivity to the volume of the older model in the line - 12,000 l / h. Without the use of additional functions, the operating speed is 3000 l / h, the kit also includes one print head and a knife for scoring and punching of printed products (see http://www.div-trade.ru/cgi-bin/wgd.cgi? gid = 209661 & cid = 232 & fid = 392).

The known device is widely used in printing enterprises. However, due to the considerable time of the adjustment work, the device does not provide for the efficient execution of perforation of single specimens. In addition, the device has a high price.

The analysis showed that there are no analogues to the developed device.

The objective of the utility model is to create a low-cost device that does not require high qualification of production personnel and ensures the rapid application of perforation on individual copies of printing products.

The technical result is the simplicity of the design of the device and manufacturability in the manufacture.

The problem is solved, and the technical result is achieved by the fact that the manual device for perforation contains a perforation disk; a washer, a guide sleeve, a fastener, a housing, a handle, a bar, and the perforation disk is made of tool steel in the form of a flat circular plate with a diameter of 50-70 mm and has a hole in the center for mounting the guide sleeve and the fastener according to the outer diameter of the perforation disk made flat pointed teeth, the width and pitch of the teeth depends on the material intended for perforation, has two washers made in the form of round metal plates with a diameter of 3 mm less than the diameter based I have teeth, and the guide sleeve is a metal cylinder with an external diameter equal to the diameter of the hole in the center of the perforation disk and the diameter of the holes in the housing, while the inner diameter is made with the possibility of freely assembling two washers and a perforation disk with the fastening element in the body eyes and the case is made of a stamping metal plate with stops in the upper part under the fingers of the working personnel, in the bifurcated upper part of the body Eyelets are provided for fixing the two washers and the perforating disc with a fastener.

The bar is made of tool steel in the form of a flat plate with dimensions not less than the wide side of an A4 sheet and 5 millimeters thick, while along the entire long side of the plate there are three milling grooves for a perforating disc, the width of the first groove is equal to the thickness of the upper part of the tooth, the width of the second groove equal to the thickness of the tooth in its middle part, the width of the third groove is equal to the thickness of the tooth at its base, when perforating, the width of the grooves is chosen different based on the density of paper or materials.

The utility model is illustrated in the drawing, which shows a diagram of a manual device for perforation. In the drawing are indicated:

1. perforation disc

2. washers,

3. guide sleeve,

4. fastener

5. housing

6. crank

7. bar.

. Implementation of a utility model.

The manual device for perforation consists of a perforating device and strap 7.

The perforating device consists of a perforating disk 1, washers 2, a guide sleeve 3, a fastener 4, a housing 5, a handle 6.

The perforation disk 1 is made of tool steel in the form of a flat plate of circular shape with a diameter of 50-70 mm and has a hole in the center for mounting the guide sleeve 3 and the fastening element 4. Flat pointed teeth are made along the outer diameter of the perforation disk 1. The width and pitch of the teeth depends on the material intended for perforation.

The washer 2 is made in the form of a metal plate of circular shape with a diameter of 3 mm less than the diameter of the base of the teeth. For normal operation, the punch kit includes two washers.

The guide sleeve 3 is a metal cylinder with an external diameter equal to the diameter of the hole in the center of the perforation disk 1 and the diameter of the hole of the housing 5. The inner diameter is made with the possibility of freely assembling the eyes of the housing 5 with two fasteners 4, two washers 2 and perforation disk 1 with the fastener .

The housing 5 is made of a stamping metal plate with stops in the upper part under the fingers of the working personnel. In the bifurcated upper part, the housing 5 has eyes for fixing by a fastener 4 two washers 2 and a perforation disk 1.

In the upper part of the handle 6, the housing 5 is fixed.

The bar 7 is made of tool steel in the form of a flat plate with dimensions not less than the wide side of an A4 sheet and 5 mm thick. In the plate along the entire long side there are three milling grooves for the perforating disc 1. The width of the first groove is equal to the thickness of the upper part of the tooth. The width of the second groove is equal to the thickness of the tooth in its middle part. The width of the third groove is equal to the thickness of the tooth at its base. The width of the grooves is selected depending on the density of the paper or perforated material.

The operation of the device.

Before performing punching operations with a manual punching device, the punching disk 1 is inserted between the washers 2 in the housing 5, the guide sleeve 3 is installed, fixing the entire assembly with the fastener 4, and then inserted in the assembled form into the handle 6.

The bar 7 is placed on a horizontal surface.

Single copies of printed products are laid on the bar 7, so that the perforation line coincides with the milling groove on the bar 7, which corresponds to the selected paper or material density. The bookbinder, pressing on the perforating device, conducts paper or material on the perforating disk 1, inserting it at the beginning of the milling groove on the bar 7.

The use of a manual device for perforation does not require high qualification of production personnel and ensures the rapid application of perforation on individual copies of printing products. In addition, it has a simple design, low cost and is technologically advanced to manufacture.
