Description

1 The invention relates to process equipment for the manufacture of sections of coils of linear electrically driven machines. A device for stretching the stator winding sections is known, which contains a stretching mechanism with clamps for fastening the groove parts of the blanks, frontal holders and no. 1 pneumatic braid. The disadvantage of this device is low productivity due to the impossibility of performing the operations of crimping and shaping the coil sections in it. A known machine for stretching and forming coils of a loop core winding, comprising a frame, a mechanism for fixing a coil head, a mechanism for fixing groove parts of coils, a mechanism for spatial forming, a drive PJ. However, it is not possible to carry out the operation of crimping the grooved parts of the coils on a known device, which is to be carried out on other devices B, which significantly reduces the productivity. The purpose of the invention is to increase productivity. Dp achieve the goal in the device for manufacturing the coils of the stators of electric machines, containing the base, the mechanisms for fixing the slotted parts of the gear and the mechanisms for fixing the heads of the coil, each of the mechanisms for fixing the slot parts of the coil is made in the form of a split mold consisting of two pivotally interconnected parts, each of the mechanisms for fixing the heads of the coil is equipped with a drive of reciprocating movement to bend the front part of the coil and is installed with a The relatively NOSTA transverse movement of the longitudinal axis of the press-form a mold mounted for relative movement in mutually perpendicular planes. Figure 1 shows a device for producing stators coils, a general view; Fig. 2 is a kinematic scheme of the Machai fixed to the coil heads; Fig. 3 shows the kinematic scheme of the mechanisms for fixing the groove parts of the coil; FIG. 4 is a diagram 714 of operation of the device, the initial stage; fig.Z - the same at the time of crimping groove parts of the coil; Fig. 6 is the same when the coil is stretched. The device comprises a base 1, to which a vertical actuator 2 is attached for crimping the groove parts, a horizontal drive 3 for stretching the coils, two actuators 4 for leveling the coil frontal parts, locking mechanisms for the coil grooves and locking mechanisms for the frontal parts. Each of the fastening mechanisms of the frontal parts contains clamps 5, freely mounted on the axis 6 and having the possibility of reciprocating movement for turning the frontal part away from the actuator 4. Each of the mechanisms for fixing the groove parts of the coil is made in the form of a detachable mold 7 or 8, the mold 7 is connected to the actuator 2, and the mold 8 is placed in the lock 9 associated with the actuator 3, the spring form 7 consists of press strips II and 12 connected by a hinge 10. 12. The heating bar 11 is mounted in the press bar 11 element 13 and in press strip 12 you The cooling reagent channels 14 are complete. The lock 9 consists of the body 15 and the cover 16, the body and the cover are connected by a hinge 17. The spacers 18 and 19 of the mold 8 are connected by a hinge 20 and are placed in the slot of the lock 9. A heating plate is mounted in the press bar 18 element 21, and chambers 22 for cooling agent are made in press bar 19. The device works as follows. Both groove parts 23 and 24 of the boat blanks are laid in the opened press strips of the press molds 7 and 8. The heads of the coil front parts are fixed in the grippers 5. The press strips 18 and 19 are pre-fixed in the covered position with the lock 9, and the press - plates 1 and 12 - clamp-sh (not shown). When the actuator 2 is turned on, the mold 7 moves down to the stop; , the press strips 18 and 19, while the pressplan 1I rotates on the hinge 10 all the way into the faces of the press plank 12. The lower press strips 18 and 19, perceived the vertical force from the press plank 11, also close, as the bottom of the lock 9 made wedge-shaped. 310 a cover i6 has a bevel on which the beveled edge of the press plate 18 finds. The touching edges of the press plates and the lock are machined so that in the closed position they provide the required size, crimped groove parts of the coil and their pressure testing. After compressing the press bars, the heating elements are turned on. The exposure time depends on the size of the coil and the thickness of the insulation. After crimping, drive 2 is turned off and turns on 14A with drive 3 — the coil is stretched to the laying spacing distance, while the coil heads move with the grippers 5 along base 6 to a distance equal to half the step. When the actuators 4 are turned on, the grippers move upward by bending the front parts. The combination of several operations on one device allows to increase productivity and ensure high quality of the coil sections.
