The method of connecting parts is as follows. In the walls 1 (Fig. 1-6) of the first part 2 (Fig. 1-5), which is an external case, which is made in the form of a box-section profile, seven through holes 3 (Figs. 1, 3-5) of the same diameter are drilled with a drill for example 1.1 mm. In the third part 4 (Fig. 1, 2, 4, 6) three blind grooves 5 are milled to form a flat element 6 (Fig. 4, 6) with two slots 7 in each of them. Then, in the third part 4 (Fig. 1, 2, 4, 6), walls 1 (Fig. 1-6) are formed until a profile 8 (Fig. 1, 2, 4, 6) of the box section is formed by means of a stamp. Each blind groove 5 is performed to a depth equal to at least half the wall thickness 1 (Fig. 1-6) of the third part 4 (Fig. 1, 2, 4, 6) in the form of a box-shaped profile 8. The width of each flat element 6 (Fig. 4, 6) is performed with a size equal to at least the diameter of one through hole 3 (Fig. 1, 3-5) in the walls of the first part 2 (Fig. 1-5). Each slot 7 (Fig. 4, 6) is made with a length equal to the size of at least two diameters of one through hole 3 (Fig. 1, 3-5) in the walls of the first part 2 (Fig. 1-5). The width of the slot 7 (Fig. 4, 6) is equal to the diameter of the through hole 3 (Fig. 1, 3-5) in the walls of the first part 2 (Fig. 1-5). Flat element 6 (Fig. 4, 6) is cut using laser cutting with the HPN 500P laser technological complex (laser type: YAG: Nd; radiation wavelength 1.06 μm; average output power 450 W; pulse repetition rate 60- 80 Hz; positioning accuracy 0.1 mm; cutting time 50 sec.). In the inner part of the first part 2 (Fig. 1-5) coaxially install (installation) the third part 4 (Fig. 1, 2, 4, 6). This is due to the fact that the dimensions of the outer surfaces of the walls 1 (Fig. 1-6) of the attached third part 4 (Figs. 1, 2, 4, 6) in the form of a box-shaped profile 8 correspond to (are equal to) the dimensions of the inner surfaces of the walls 1 ( Fig. 1-6) of the first part 2 (Fig. 1-5). Four second parts 9 (Figs. 1, 3, 4, 7) are made in the mold according to Figs. 7, each of which is made in the form of a three-stage cylindrical rod. In the walls 1 (Fig. 1-6) of the third part 4 (Fig. 1, 2, 4, 6), four through holes 10 (Fig. 1, 4, 6) are drilled coaxial to the through holes 3 (Figs. 1, 3-5 ) of the first part 2 (Fig. 1-5). All through holes 10 (Figs. 1, 4, 6) (Fig. 16) are made with the same diameters, for example, 1.1 mm. In the four holes 3 (Fig. 1, 3-56), 10 (Fig. 1, 4, 6) of the first 2 (Fig. 1-5) and third 4 (Fig. 1, 2, 4, 6) parts, the first steps 11 (Fig. 1, 7) of the four second parts 9 (Figs. 1, 3, 4, 7) so that the outer end faces 12 (Figs. 1, 7) of the second steps 13 (Figs. 1, 4, 7 ) of the second parts 9 (Figs. 1, 3, 4, 7) were in contact with the inner side 14 (Figs. 1, 4, 6) of the third part 4 (Figs. 1, 2, 4, 6). Connect the first 2 (Fig. 1-5) and third 4 (Fig. 1, 2, 4, 6) parts by unfastening the end parts 15 (Fig. 1, 4, 7) of the first stages 11 (Fig. 1, 7) of four second parts 9 (Fig. 1, 3, 4, 7) from the outside 16 (Fig. 1, 2, 4, 5) of the first part 2 (Fig. 1-5) with the formation of rivets 17 (Fig. 1, 4) . Assemble (connect) the base 18 (Fig. 1, 2) with the liner 19 (Fig. 1) with the formation of the fourth part 20 (Fig. 1, 2). Connect the fourth part 20 to the connected (assembled) first 2 (Fig. 1-5) and third 4 (Fig. 1, 2, 4, 6) parts so that on one side the end side 21 (Fig. 1) of the fourth details 20 (Fig. 1, 2) rested on the cylindrical parts 22 (Figs. 1, 4, 7) of the third steps 23 of the four second parts 9 (Figs. 1, 3, 4, 7). The housing 24 (Fig. 1-3, 8) of the device in the form of a box-section profile with three threaded holes 25 made in it, located on its side surface and coaxial through holes 3 (Fig. 1, 3-5) in the walls of the first part 2 (Fig. 1-5), coaxially mounted on the first part 2. Install the latch 26 (Fig. 1-3, 8) on the end side 27 of the housing 24 (Fig. 1-3, 8) of the device using two screws 28 (Fig. . 1, 3, 8). By rotating the screws 28, the latch 26 (Figs. 1-3, 8) is manually shifted against the end face 27 (Figs. 1, 3, 8) of the device body 24 (Figs. 1-3, 8), thus ensuring the installation of the fourth part 20 (Fig. 1, 2) point blank with cylindrical parts 22 (Fig. 1, 4, 7) of the third stages 23 (Fig. 1, 4, 7) of the second parts 9 (Fig. 1, 3, 4, 7). The washer 29 (Fig. 1-3, 8), designed to change the geometric dimensions of the bending, is installed between the end face of the punch 30 and the wall 1 (Fig. 1-6) of the first part 2 (Fig. 1-5). Three punches 30 (Figs. 1-3, 8) with handles 31 and washers 29 are screwed alternately into the three threaded holes 25 of the device body 24. Manually alternately rotate the handles 31 of the punches 30 until the tips 32 of the punches 30 under the influence of the applied pressure will abut against the flat elements 6 (Fig. 4, 6) with two slots 7. The tips 32 (Figs. 1-3, 8) of the punches 30 are pressed into the central holes (not shown in Fig.) of the punches 30. Next, the handles 31 continue to rotate three punches 30 to the stop with washers 29, which ensures the formation (bending) of three pl Oskoi elements 6 (Fig. 4, 6) with two slots 7 until they form a curved V-shaped shape 33 (Fig. 1, 2) to ensure that the inner end side 34 (Fig. 1) of the formed elements 33 (Fig. 1, 2) to the other end side 35 (Fig. 1) of the fourth part 20 (Fig. 1, 2) from the side of the base 18. The latch 26 (Figs. 1-3, 8) is made of AMg6 plate GOST 17232-99. Punches 30 are made of material circle 40X-1 GOST 4543-71. The tip 32 of the punch 30 is made of wire B-2A-1,2 GOST 9389-75. The handle 31 of the punch 30 is made of material circle 45-BT-GOST 1051-73. Washers 29 are made from pipe B 20 GOST 8733-74. The presence of three stages 11 (Fig. 1, 7), 1 3 (Fig. 1, 4, 7), 23 in the four second parts 9 (Fig. 1, 3, 4, 7) allows you to connect the three parts 2 (Fig. 1 -5), 4 (Fig. 1, 2, 4, 6), 20 (Fig. 1, 2) at the same time.

A device for connecting parts contains a housing 24 (Fig. 1-3, 8) in the form of a box-section profile and three screw pairs 36 (Figs. 1-3, 8). The first threaded surface 37 (Fig. 1, 2, 8) in each screw pair 36 (Figs. 1-3, 8) is made in the threaded hole 25 on the three side surfaces 38 of the housing 24 (Figs. 1-3, 8) of the device in profile view of the box section. On the end side 27 (Figs. 1, 3, 8) of the housing of the device 24 (Figs. 1-3, 8), two threaded holes 39 (Figs. 1, 8) are made in the form of a box-section profile for mounting the lock 26 of Figs. 1-3, 8) using two screws 28 (Fig. 1, 3, 8). Screws 28 are made of material 40X-1 GOST 4543-71, they are performed with direct corrugations according to GOST 21474-75, which ensures ease of use. The second threaded 40 (Fig. 1, 2, 8) surface in each screw pair 36 (Figs. 1-3, 8) is located on the cylindrical part 41 of the punch, which is made with a handle 31 and a tip 32, pressed into its Central hole 42, forming three nodes 43 are flexible. The nodes 43 are made of bending installed in the threaded holes 25 (Fig. 1-3, 8) of the housing 24 of the device in the form of a box-shaped section. To obtain different geometric dimensions of the molded element 33 (Fig. 1, 2) of a "V" -shaped washer 29 (Figs. 1-3, 8) of different thicknesses are used.

The proposed device allows you to connect parts by forming a flat element 6 (Fig. 4, 6) until it forms a curved "V" -shaped shape 33 (Fig. 1, 2) without using a matrix. This is achieved by the fact that the device has a blind groove 5 (Fig. 1, 2, 4, 6) with a depth equal to half the thickness of the wall 1 (Fig. 1-6), a flat element 8 is made (Fig. 1, 2, 4 , 6) with two slots 7 (Fig. 4, 6) and a thickness equal to half the thickness of the wall 1 (Fig. 1-6), and since outside the blind groove 5 (Fig. 1, 2, 4, 6) the wall thickness 1 (Fig. 1-6) is a size that is two times the thickness of the flat element 6 (Fig. 4, 6), then the wall 1 (Fig. 1-6) and the flat element 6 (Fig. 4, 6) with two slots perform the function of a matrix. Thus, the proposed device operates without a matrix.

A device for connecting parts works as follows. The housing 24 (Figs. 1-3, 8) of the device with three threaded holes 25 made therein, located on its side surface 38 and coaxial through holes 3 (Figs. 1, 3-5) in the walls of the first part 2 (Fig. 1 -5), coaxially mounted on the first part 2. Then install the latch 26 (Fig. 1-3, 8) on the end side 27 (Fig. 1, 3, 8) of the housing 24 (Fig. 1-3, 8) of the device when using two screws 28 (Fig. 1, 3, 8). By rotating the two screws 28, the latch 26 (Figs. 1-3, 8) is moved all the way to the end side 27 (Figs. 1, 3, 8) of the device body 24 (Figs. 1-3, 8), providing the installation of the fourth part 20 ( Fig. 1, 2) point-blank with the cylindrical part 22 (Fig. 1, 4, 7) of the third stage 23 of the second part 9 (Fig. 1, 3, 4, 7). Three punches 30 (Figs. 1-3, 8) with handles 31 and washers 29 are installed in the three threaded holes 25 of the device body 24. Then, the handles 31 of the punches 30 are rotated alternately until the tips 32 of the punches 30 abut against the flat elements 6 (Fig. 4, 6) with two slots 7. Continue to rotate the handles 31 (Figs. 1-3, 8) of the punches 30 until they stop with washers 29, provide bending of three flat elements 6 (Figs. 4, 6) with two slots 7 with the formation of a curved V-shaped shape 33 (Fig. 1, 2), this ensures the fixation of the inner end side 34 (Fig. 1) formed e elements of a V-shaped form 33 (Fig. 1, 2) to the end side 35 (Fig. 1) of the fourth part 20 (Fig. 1, 2).

Thus, the proposed group of inventions allows portable assembly of parts by forming a curved V-shaped 33 (Fig. 1, 2) of the flat element 6 (Fig. 4, 6) in different hard-to-reach places and planes of parts inside the product without using a matrix, which significantly simplifies the device and method of bending parts in the process of assembly (connection). The need for a matrix as a tool disappears due to the fact that in the bending zone the thickness of the flat element 6 (Fig. 4, 6) with two slots 7 is made to a depth of at least half the wall thickness 1 (Fig. 1-6) of the third part 2 (Fig. . 1-5), and outside the bending zone - it is equal to the wall thickness 1 (Fig. 1-6) of the third part 4 (Fig. 1, 2, 4, 6).
