Device for applying a pattern on the sheet product

 

(57) Abstract:

Usage: drawing a pattern on the workpiece with the aid of stencils. The inventive device includes a base plate and a stencil. The base plate is mounted obliquely on the base and has guide plates and pins for fixing the stencil. The stencil is made in the form of a package leaves the United cap rivet with the possibility of blanket disclosure, and has a fixing hole. Each sheet is made in the form of elastic foundations woven material, such as Mylar or cambric vellum, on which is plotted the contours of the elements of the figure, and connected the adhesive material (adhesive) polymer films. On leaves formed through holes for applying through their pattern. 4 C.p. f-crystals, 4 Il.

The invention relates to a device for applying a pattern on a sheet products using stencil and may find wide application in the manufacture of mirrors coated on their surface patterns sandblasting gun.

A device for applying a pattern on a sheet article containing a reference tool and stencil [1].

However, in this device, the stencil is made in the form of a rigid plate, in achiev is formed in the gap fly ejected at high speed from sandblasting gun abrasive particles, creating fuzzy blurred the outline of the pattern. This reduces the quality of the product and its artistic appearance. In addition, the leaves of the stencil is made separate and megatraveller applying the patterns are not excluded confusion, and their personal installation, fixation with subsequent removal from the base takes a lot of time, which reduces productivity.

The purpose of the invention is improving the quality of the pattern caused by the jet of abrasive material, and increase the service life of the device.

This objective is achieved in that the device for applying a pattern on a sheet article containing the stencil with Windows for applying through their pattern on the product support plate and clamps for installation of it products and stencil, the stencil is made of at least one multi-layer sheet, the middle layer which contains an elastic basis, for example, of woven material such as Mylar or cambric vellum, and the exterior is made from PVC film.

The stencil can be made of United in one corner of the cap rivet package stencil sheets, which are displaced one relative to another.

The base plate is fixed on the base oblique, and ELAS is>Clamps for installation on the base plate is made as mounted at right angles to the rails, and for the stencil sheet in the form attached to the base of the pins, one of which passes through a hole cap rivets.

In Fig. 1 shows the device in side view; Fig. 2 is a view along arrow a in Fig. 1; Fig. 3 - section b-B in Fig. 2 (showing the design of the stencil sheet); Fig. 4 - compound leaves stencil in the package.

Device for applying a pattern on the sheet product comprises a base 1, on which the inclined fixed base plate 2 with a bottom 3 and side 4 of the bounding rails, not exceeding in height the thickness of the sheet product. Reiki serve for fixing the position of the item on the plate. The top two corners and the bottom one, beyond the margins of the sheet product, the base plate is fixed pins 5 and axis 6.

The pins are made with the same cone tops and exceed the height of the rails. The axis has a bottom level 7, equal to the thickness of the product, and at the top is provided with an annular groove 8 for installation in her lock washer 9.

The stencil 10 is made in the form of a package of flexible sheets 11, connected by a cap rivet 12 with the possibility of blanket disclosure. Each is th vellum, and the exterior is made from PVC film 14. On each sheet is formed unmatched in the package ears 15 for easy gripping of the sheet when it is placed on pins and offset one relative to another window 16-18 for applying through them pattern 19 on the sheet product 20 and the locking holes 21 at the corners of the sheet.

The device is used as follows.

When removed from the pins 5 and deployed downward around the axis 6 sheets 11 on the lower guide rail 3 on the support plate 2 install the glass or any other flat article 20 and pulls it to the side rail 4 is fixed in its position.

After this eyelet 15 of the lower sheet 11 is turned around the cap of the rivet 12 up, fix holes 21 on pins 5 and iron hand to remove air between the sheet and the glass. The resulting static electropole contributes to the tight connection of the sheet glass.

After that jet-abrasive device through the Windows 16 of the first (lower) leaf stencil is applied with a jet of abrasive particles pattern 19 on the glass 20. Then remove the first sheet and install in the same way the second window 17 which do not coincide with printed pattern, and less effectivename, the average of which is made on the basis of elastic, for example of Mylar cambric or vellum, and the exterior is made from PVC film, provides worksheets flexibility, durability and a snug fit of the stencil sheet to the sheet product. PVC film treats without destroying multiple abrasive particles emitted with high kinetic energy of the jet-abrasive device. This increases the service life of the stencil, and also allows you to get a clear prasmatic the outline of the pattern.

The application of the proposed device for applying a pattern on the sheet product allows you to get quality designs with great performance. For the manufacture of a pattern with three stencils takes only 25-30 with its two surfaces when applying symmetrical or mirror-type pattern.
