Description

.. ..- I, the Invention relates to the glass industry and is intended to produce on an automatic machine a sectional FO type of bottles of various assortment, having the form of bodies of rotation of a variable cross section. The known rough form has an internal working surface in the form of a body of rotation with a variable cross section forming the configuration of the rough article t J However, this rough form does not allow to obtain high-quality products on section-type glass-forming machines. In addition, the products obtained from the product are characterized by high weight and low strength characteristics. Also known is a rough form for the production of wine bottles with a capacity of 0.7 liters SGOST 10117-72 |, internal. the cavity of which is described by a series of equations fzj. However, this rough is used on low-capacity (up to 26 units / min) carousel type machines, for example, AB-6; 2-LAM, with intermittent motion, producing up to 25 glassware per minute. . The use of such a rough form on high-performance (up to 50 pcs / min) sectional automaton does not give positive results, since the form does not satisfy the optimal thermal conditions for the formation of sectional automata. Closest to the invention. According to the technical essence and the effect achieved, it is a rough form for producing narrow-necked bottles (GOST 10117-72 and GOST 10117-80 type O, 2, O, 5 and O, with a capacity of 7 liters for wine. This black form contains a part curved section sections and intermediate sections of variable section, the profile of the side surfaces of which is described by the equations y b / f DLI O - X $ I) y 1dx-fbj for 15 x 25, y bi for 26 5 x 4-b for 65 5 XS 7 where X is the current coordinate along the shape axis in increments, mm; - current coordinate perpendicular to the axis of the form, mm; Igx is the decimal logarithm of the values of X, the coefficients a, a, a, a. B, bj b-ji b, and the pitch h are dependent on a capacious 22; . . these products and lie within; , 01 | -0.172; L-3,591-19,227; h-1,5S5. Internal working, part of each of the draft forms for bottles of 0,2; 0.5 and 0.7 l consists of i sections. The profile of each section is determined by the above equations. When using | by making rough forms with this configuration, the profile of the inner, working cavity can get high-quality narrow-neck bottles for a wine with a capacity of 0.2; 0.5 and 0.7 l of p6 GOST 10117-72 and GOST 10117-80 on sectional glass forming machines with uniform distribution of glass, improved strength and performance characteristics of the NW However, the use of these rough forms in the manufacture of another range according to GOST 10117-80 / for example bottles for horses, beer, etc. do not give positive results. The purpose of the invention is. obtaining high-quality low-weight glass products due to uniform distribution of glass. The goal is achieved by the fact that in draft form to a sectional glass-forming automaton having an internal working cavity in the form of a Rotation body with a curvilinear section and sections of variable cross section, the sections of its working cavity are described according to the equations: 0 1 D - a 3 R.; III jd3- | D, -Ь h {1-е) Н, where dp, d. , d, d, r,, r, are the diameters, the radii of the conjugation and. Pf f, RI RI Н rough form height — diameters, conjugation radii and height of the finished product, mm; a., .a, .b, c - coefficients, per. hanging from the geometry of the product and lying in

within a, 0.5-0.7; , and, 04. . 0.05.

FIG. 1 shows the finished product, a general view; figure 2 - black form, General view.

The inner working part of the form consists of 3 sections 1.11 and 111, two. of which variable cross-section and one / rivolineogr with a smooth transition from one site to another.

The profile of each section is defined as follows.

The site of the variable section do D - a,

where d.- diameter of the rough form on the interface line of the throat part with the shoulder, mm; D is the diameter of the finished product under

chord throat, mm; a is a coefficient depending on the geometry of the product and lying in the range of 1-1.5.

The diameters obtained from the equations given below form a pro-, fil area of the internal cavity of the rough form for producing bottles according to GOST 10117-80.

The obtained values of the diameters allow to obtain the profile III of the section 5 of a variable cross section of the internal cavity of the draft form.

The height of the internal cavity of the rough form, without taking into account the height of the forming part of the neck ring and the height 0 of the bottom of the bottom part of the product, is determined by the values of the equation I (1-с) Н where h is the height of the internal cavity of the rough form, mm; H is the height of the finished product without taking into account the height of the forming part of the neck ring and the height of the bottom of the bottom part, mm; c is a coefficient depending on the geometry of the product and lying within 0, OD0, 05.

When using rough forms with such a configuration, the profile of the internal working cavity makes it possible to obtain high-quality narrow-mouth bottles of various assortment and different capacity according to GOST 10117-80 on sectional glass-forming IS-type machines with a simultaneous decrease in their mass within 5-20, with a good distribution of glass melt. finished products.

Receiving bottles occurs as follows.

A drip of glass melt is fed into a rough form. Due to the fact that

5, the profile of the internal cavity, namely its throat part, corresponds to the configuration of the drop, the necessary conditions for filling the working cavity are created. Process prior

50 blowing and shaping the pulp occurs in a shorter time, since the proposed internal cavity profile is economical from the point of view of heat exchange, which allows one to sew the material consumption of glassware and at the same time economically expend the energy of sectional glass-breaking automata. s, 1 the application of the invention allows to obtain high-quality products According to GOST 10117 БО of various assortment and capacity, to achieve the optimal molding mode and uniformly 030322 about the distribution of beets on the body of products, to ensure a reduction in the mass of products during production on automatic section type b within 55 2P.
