The working principle of the full-automatic heat-shrinkage pipe penetrating machine is as follows:
firstly, a pipe cutting mechanism cuts a heat-shrinkable pipe conveyed by a pipe conveying mechanism into heat-shrinkable pipe sections with preset length, then a pipe clamping tool clamps one end of the heat-shrinkable pipe section, a pipe expanding piece of a pipe expanding mechanism stretches into the heat-shrinkable pipe sections from the other end of the heat-shrinkable pipe sections under the drive of an axis reciprocating driving mechanism and moves a preset distance (the preset distance is determined according to the specific size of the heat-shrinkable pipe and is generally 1/5-1/4 of the diameter of the heat-shrinkable pipe) in the direction away from the central axis of the heat-shrinkable pipe sections under the drive of a vertical reciprocating driving mechanism, so that the end parts of the heat-shrinkable pipe sections are expanded, and then the heat-shrinkable pipe sections are loosened by the pipe clamping tool, and the heat-shrinkable pipe sections are fixed by the pipe expanding piece; simultaneously, the wire cutting mechanism cuts the wire conveyed by the wire feeding mechanism into wire segments with preset lengths; then the wire rod section is clamped by the pipe penetrating mechanism, the end part of the wire rod section is aligned with the expansion end (namely, the end where the pipe expanding piece is positioned) of the heat-shrinkable tube section, the wire rod section is inserted into the heat-shrinkable tube section by the pipe penetrating mechanism, and the end part of the wire rod section penetrates through the heat-shrinkable tube section, so that the heat-shrinkable tube section is sleeved on the wire rod section; finally, the pipe expanding piece of the pipe expanding mechanism moves towards the central axis direction of the heat shrinkage pipe section under the drive of the vertical reciprocating driving mechanism, so that the pipe expanding piece is separated from contact with the inner wall of the heat shrinkage pipe (or the pressure between the pipe expanding piece and the inner wall of the heat shrinkage pipe is reduced), and then the pipe expanding piece of the pipe expanding mechanism moves out of the heat shrinkage pipe section under the drive of the axial reciprocating driving mechanism, so that the whole pipe penetrating operation is completed.
The pipe clamping tool can adopt a manipulator common in the industry, and the axis reciprocating driving mechanism and the vertical reciprocating driving mechanism can adopt a cylinder or a lead screw nut, because the cylinder or the lead screw nut is a well-known prior art, and the description is omitted here.
Further, the pipe expanding mechanism is arranged on a reciprocating frame, and the reciprocating frame is movably arranged on the frame, so that the pipe expanding mechanism can reciprocate between the pipe cutting mechanism and the pipe penetrating mechanism. Therefore, the pipe cutting mechanism and the pipe penetrating mechanism can be separated by a certain distance, and mutual interference caused by too close distance can be avoided when the pipe cutting mechanism and the pipe penetrating mechanism work simultaneously. The reciprocating frame may be driven by a cylinder, and will not be described here.
Further, the pipe expanding piece is connected with the vertical reciprocating driving mechanism through the guide block, the guide block is provided with a wire guiding surface at one side facing the pipe penetrating mechanism, a heat shrinkage pipe guiding surface is provided at one side facing the pipe clamping tool, and the wire guiding surface and the heat shrinkage pipe guiding surface are both cambered surfaces or inclined structures.

Further, the section of the expansion pipe piece is arc-shaped so as to adapt to the shape of the inner wall of the heat shrinkage pipe, thereby reducing or avoiding the damage of the expansion pipe piece to the heat shrinkage pipe in the pipe expansion process.
Further, the threading mechanism is composed of a wire feeder and a wire clamping manipulator which moves back and forth, and the wire feeder comprises a wire feeding wheel, an auxiliary clamping structure which is arranged opposite to the wire feeding wheel and a rotation driving mechanism which drives the wire feeding wheel to rotate. The wire clamping mechanical arm clamps and moves the cut wire segments to a gap between an auxiliary clamping structure of the wire feeder and the wire feeding wheel, and the wire segments can be sent out forwards through rotation of the wire feeding wheel, so that the wire segments are inserted into the heat-shrinkable tube segment.
Further, the wire feeder is connected with the rack through a wire feeder support, a wire clamping cylinder is mounted on the wire feeder support, an auxiliary clamping structure is mounted on a piston rod of the wire clamping cylinder, and the wire feeding wheel is mounted on the wire feeder support through a rotating shaft. The clearance between wire feeding wheel and the auxiliary clamping structure is adjustable, the cylinder can drive the auxiliary clamping structure to move up and down, when wire feeding is carried out, the auxiliary clamping structure is firstly moved upwards, the clearance between the auxiliary clamping structure and the wire feeding wheel is increased, then the wire clamping manipulator clamps and transfers the cut wire section to the clearance between the auxiliary clamping structure and the wire feeding wheel, the auxiliary clamping structure moves downwards under the driving of the cylinder to clamp the wire section together with the wire feeding wheel, and finally the wire clamping manipulator loosens the wire section, and the wire feeding wheel rotates under the driving of the rotation driving mechanism to insert the wire section into the heat shrinkage pipe section.
Further, two pipe clamping tools are respectively arranged at the sides of the pipe cutting mechanism and the pipe penetrating mechanism, wherein one pipe clamping tool is used for clamping the heat-shrinkable pipe section before pipe expansion so as to facilitate the insertion of the pipe expansion into the heat-shrinkable pipe section; the other pipe clamping tool is used for clamping the heat-shrinkable tube section and the wire rod section after the pipe is penetrated so as to facilitate the removal of the expansion pipe section from the heat-shrinkable tube section.
Further, the pipe cutting mechanism is arranged on the reciprocating frame, the distance between the pipe cutting mechanism and the pipe expanding mechanism is equal to the distance between the two pipe clamping tools, so that in the reciprocating movement process of the reciprocating frame, the pipe expanding mechanism is aligned with the two pipe clamping tools in turn, and the pipe cutting mechanism is aligned with the first pipe clamping tool at intervals, and continuous operation can be realized, and the concrete principle is as follows: when the pipe cutting mechanism is aligned with the first pipe clamping tool, the first pipe clamping tool clamps one end of the cut heat-shrinkable pipe section, and the pipe expanding mechanism is aligned with the second pipe clamping tool at the moment so as to be used for pipe penetrating operation of the wire rod section; when the reciprocating travelling frame moves to the maximum stroke in the direction of the first pipe clamping tool, the pipe expanding mechanism is aligned with the first pipe clamping tool, so that pipe expanding operation can be performed; when the reciprocating travelling frame moves towards the second pipe clamping tool, the pipe expanding mechanism can move to the second pipe clamping tool along with the heat shrinkage pipe section to perform pipe penetrating operation, and meanwhile, the first pipe clamping tool performs pipe cutting operation.

At the same time, the wire cutting mechanism 7 cuts the wire conveyed by the wire feeding mechanism 6 into wire segments 11 of a predetermined length; the wire clamping mechanical arm clamps and moves the cut wire segment 11 to a gap between two wire feeding wheels 811 of the wire feeder 81, the two wire feeding wheels 811 clamp the wire segment 11 and enable the end of the wire segment 11 to be aligned with the expansion end of the heat-shrinkable tube segment 10, the wire clamping mechanical arm loosens the wire segment 11, the wire feeding wheels 811 rotate under the drive of the rotation driving mechanism 82 so as to drive the wire segment 11 to move, the wire segment 11 is inserted into the heat-shrinkable tube segment 10 (shown in fig. 9), the wire feeding wheels 811 continue to rotate, the end of the wire segment 11 penetrates through the heat-shrinkable tube segment 10, and the heat-shrinkable tube segment 10 is sleeved on the wire segment 11; as shown in fig. 10, the second pipe clamping tool 42 close to the pipe penetrating mechanism 8 clamps one end of the heat-shrinkable pipe section 10 and the wire section 11 inside the heat-shrinkable pipe section, the pipe expanding piece 51 of the pipe expanding mechanism 5 moves towards the central axis direction of the heat-shrinkable pipe section 10 under the driving of the vertical reciprocating driving mechanism, so that the pipe expanding piece 51 is separated from the inner wall of the heat-shrinkable pipe section 10 (or the pressure between the pipe expanding piece 51 and the inner wall of the heat-shrinkable pipe section 10 is reduced), then as shown in fig. 11, the pipe expanding piece 51 of the pipe expanding mechanism 5 moves out of the heat-shrinkable pipe section 10 under the driving of the axial reciprocating driving mechanism, the whole pipe penetrating operation is completed, finally as shown in fig. 12, the pipe expanding piece 51 of the pipe expanding mechanism 5 moves towards the direction far away from the central axis direction of the heat-shrinkable pipe section 10 under the driving of the vertical reciprocating driving mechanism, and the second pipe clamping tool 42 and the wire feeding wheel 811 are loosened, and the wire section 11 penetrating the heat-shrinkable pipe section 10 is taken out for subsequent operation.
While the invention has been described above with reference to the accompanying drawings, it will be apparent that the specific design of the invention is not limited by the foregoing, but it is within the scope of the invention to apply the inventive concept and technical scheme directly to other occasions without any substantial improvement or improvement.
