Figure 1 presents the matrix, oblly view; figure 2 is a section of the LA in figure 1; on fig.Z section bb in fig, 1.

The pressing machine for the semi-fabriquets contains a channel that includes the forming section 1, the cross section of which is variable, with an increase in width from the input stage 2 to the output 3. The ml channel 3 also switches to the viral section 4 , the cross section of which corresponds to the cross-section of the cross-section of 1 hole 4 | abrnkata. The input area of the non-reference of section 2 of the forming section 1 and the cross-sectional area of the calibrating section 4 is 0, 6., .O, K from the area of the output cross-section 3 of the forming section 1.

Mlitsa works as follows.

The extruded material is extruded through the die channel. At the same time, it first (dit through the inlet of the forms of the rutting area 1, corresponding to its input cross section 1Aem section 2, the Metal reaches the calibrating section A and begins its deformation in the transverse direction 1П1И, because the distribution force is less

than the force of the radius in the calibration section of the f channel. After riojujcTH forming section 1 is filled, metal is extruded through the outlet of the matrix channel corresponding to the calibrating section U, Since the input cross-sectional area of the forming section and the cross-sectional area of the calibration section are O, 8 ... O, 14 from the output cross-section area of the forming section The development of the structure of the pressed semifinished products in the transverse direction and reduction of the anisotropy of the mechanical properties is provided.

Thus, the use of a die for pressing semi-finished products ensures a better quality.
