Изобретение относитс к изготовлению многослойных выт нутых изделий методом прессовани многослойной заготовки через очко матрицы.The invention relates to the manufacture of multilayer extruded products by the method of pressing a multilayer preform through a matrix point.

Существующие матрицы 1 аналогичного назначени состо т из корпуса отверсти , формующего изделие по наружному слою.Existing matrices 1 of similar purpose consist of an opening body that forms a product over the outer layer.

Недостатками таких матриц вл ютс невозможность обеспечени нужной формы сечений сердечника и слоев кз цилиндрических заготовок и невысока точность заданной толщины каждого сло .The disadvantages of such matrices are the impossibility of providing the desired shape of the core sections and layers of cylindrical billets and the low accuracy of a given thickness of each layer.

Цель изобретени - повыщение точности толщины каждого сло и получение сердечника и слоев заданной формы.The purpose of the invention is to increase the accuracy of the thickness of each layer and obtain the core and layers of a given shape.

Дл этого корпус матрицы выполнен из нескольких , по числу слоев, соосно установленных частей, формообразующее отверстие первой от заготовки из которых соответствует форме и размерам сердечника готового издели , а отверстие каждой последующей части- форме и размерам последующего сло , причем втора от заготовки и последующие части имеют чащеобразную форму и стенки каждой из них расположены между стенками предыдущей и последующей частей, а между ними выполнены каналы, соедин ющие каждое формообразующее отверстие с соответствующим слоем заготовки.For this, the body of the matrix is made of several, by the number of layers, coaxially installed parts, forming the first hole from the blank of which corresponds to the shape and size of the core of the finished product, and the hole of each subsequent part is the shape and dimensions of the subsequent layer, and the second from the blank and subsequent parts each of them are located between the walls of the previous and subsequent parts, and between them there are channels connecting each forming hole with the corresponding slit it preform.

На фиг. 1 показана матрица дл прессовани трехслойного издели в продольном разрезе; на фиг. 2 - разрез по А-А на фиг. 1; на фиг. 3 - разрез по Б-Б на фиг. 1; на фиг. 4 - разрез по В-В на фит. 1.FIG. Figure 1 shows a die for pressing a three-ply article in a longitudinal section; in fig. 2 is a section along A-A in FIG. one; in fig. 3 is a section along BB in FIG. one; in fig. 4 - bb-section on fit. one.

Матрица состоит из трех последовательно соосно установленных частей 1-3, в которых выполнены формообразующие отверсти 4-6, соответствующие форме и размерам сердечника и последующих слоев в готовом изделии.The matrix consists of three sequentially coaxially installed parts 1-3, in which the shaping holes 4-6 are made, corresponding to the shape and size of the core and the subsequent layers in the finished product.

Эти отверсти соединены с соответствующими сло ми заготовки питающими каналами 7 и 8, а вокруг них (отверстий) выполнены камеры 9 и 10, в которых накапливаетс прессуемый материал. Матрица устанавливаетс вThese holes are connected to the corresponding layers of the workpiece by feeding channels 7 and 8, and around them (holes) are chambers 9 and 10, in which the compressible material accumulates. Matrix is set to

Прессование изделий через матрицу производ т следующим образом.container 11 carrying a multilayer preform with concentrically arranged layers. It is also possible to perform a matrix with a monolithic connection of all the parts in one piece. The pressing of the products through the die is performed as follows.

В контейнер 11с установленной в нем матрицей закладывают концентрически составленную из различных компонентов заготовку. Причем заготовка составл етс , а матрицаIn the container 11c with a matrix installed in it, a preform is laid concentrically composed of various components. Moreover, the workpiece is compiled, and the matrix

После распрессовки компоненты заготовки начинают течение поcalculated so that each component is against the corresponding matrix channel. Then, applying force P, begin pressing. After decompression, the components of the workpiece begin to flow.

corresponding channels. The core component flows through the central shaping hole, the next component flows through the channels 7 and the last component flows through the channels 8, respectively, entering chambers 9 and 10. The core component, filling the central shaping channel and passing through the hole 4, enters the chamber 9. V At the same time, the component of the chamber 9 compresses the shaped core along the contour and continues to move along with it and gets into the shaping hole of the 5th part

2. Pass the hole 5 of part 2, the product already has the specified shape of the second layer and enters the chamber 10. By this time, the component of the outer layer, filling the chamber 10, compresses the formed second layer with the core along the contour and continues to move along the shaping hole of the part

3. Pass the calibrating point of hole 6 of part 3, the product acquires a predetermined shape. Thus, the components entering into the internal sections of the multilayer product, regardless of the initial shape of the workpiece, use the proposed matrix to obtain the necessary configuration. Moreover, the geometrical accuracy of the dimensions of the cross sections and the accuracy of the ratio of the components constituting the cross section of a multilayer product, obtained using this matrix, is higher compared to the same products obtained from composite shaped blanks using well-known single-channel matrices.
