Detailed Description

The invention will be further described with reference to specific examples, but the scope of the invention is not limited thereto.

Embodiment 1, a winding device for a pipeline through thermoplastic mold, which is mainly divided into a feeding system and a transmission system, and further comprises a workbench 10.

A feeding system, as shown in fig. 1 to 3, comprising a low power motor 1, a screw rod 2, a fixed rod 3 and a track 4; a rail 4 is provided on the table 10.

The low-power motor 1 is connected with the screw rod 2 and drives the screw rod 2 to rotate, namely, the low-power motor 1 drives the screw rod 2 to rotate when rotating forwards or reversely; the screw rod 2 is provided with a slide block 15, a turbine is arranged in the slide block 15, and the slide block 15 is connected with the screw rod 2 in a turbine scroll rod mode, so that the slide block 15 is driven to slide along the axial direction of the screw rod 2 when the screw rod 2 rotates.

The fixing rod 3 consists of square steel 6 and a roller 5, the square steel 6 is of a hollow structure, and the roller 5 is arranged in the inner cavity of the square steel 6; the rollers 5 are arranged near the top of the square steel 6. The bottom of the square steel 6 is welded and fixed on the sliding block 15, the sliding block 15 clamped on the track 4 can slide along the track 4, and the track 4 is mainly used for supporting the sliding block 15 and ensuring the flexible sliding of the sliding block 15.

The transmission system, as shown in fig. 3, includes a high-power motor 7, a spindle box i 9, a spindle box ii 14, a belt pulley mechanism 8, a three-jaw chuck i 11, a three-jaw chuck ii 13, and a mold 12, wherein the high-power motor 7, the spindle box i 9, and the spindle box ii 14 are fixed on a worktable 10 to ensure the stability of operation.

A rotating shaft I and a hydraulic system I are arranged in the spindle box I9, and the hydraulic system I rotates along with the rotating shaft I; similarly, a rotating shaft II and a hydraulic system II are arranged in the main spindle box II 14, and the hydraulic system II rotates along with the rotating shaft II; three-jaw chuck I11 links to each other with hydraulic system I, and three-jaw chuck II 13 links to each other with hydraulic system II, and three-jaw chuck I11 and three-jaw chuck II 13 are used for pressing from both sides tight fixed with mould 12, and under hydraulic system I, hydraulic system II's effect, three-jaw chuck I11 and two 13 tight moulds 12 in top of three-jaw chuck.

The high-power motor 7 is connected with a rotating shaft in a spindle box I9 through a belt pulley mechanism 8, and the rotating shaft I of the spindle box I9, the rotating shaft II in a spindle box II 14 and the die 12 rotate coaxially.

The working mode of the transmission system is as follows: the high-power motor 7 drives the rotating shaft I of the spindle box I9 to rotate through belt transmission of the belt wheel mechanism 8, so that the die 12 and the rotating shaft II in the spindle box II 14 are driven to rotate together. Because the whole running speed of the device is lower, the coaxial synchronous rotation of the rotating shaft I of the spindle box I9, the rotating shaft II in the spindle box II 14 and the die 12 can be basically realized. In the invention, the rotating speed of the rotating shaft I of the spindle box I9 is generally controlled to be 50 +/-10 r/min.

The mold 12 is a hollow structure, and two ends of the mold 12 are respectively provided with a positioning through hole 16 for the cable to enter and exit the inner cavity of the mold 12; the cable to be wound passes through the inner cavity of the square steel 6 from bottom to top and is wound on the roller 5, then passes through a positioning through hole 16, enters the inner cavity of the die 12 and is fixed on the inner wall of the die 12; and the wire is passed out of the other positioning through hole 16 after the wire winding is completed.

The arrangement and the use of the hydraulic system I and the hydraulic system II belong to the conventional technology, so the invention is not explained in detail.

The horizontal plane of the workbench of the whole feeding system is lower than that of the workbench of the transmission system (generally lower by about 50 cm), and the circle center of the roller 5 positioned at the top of the fixed rod 3 (the top of the square steel 6) is basically consistent with the height of the center of the hole of the positioning through hole 16 on the die 12.

The invention relates to a winding device for a pipeline straight-through thermoplastic mold, which comprises the following specific implementation steps:

1) the three-jaw chuck I11 and the three-jaw chuck II 13 clamp and fix two ends of the die 12 respectively; before the work is started, the hydraulic system I and the hydraulic system II are started, so that the three-jaw chuck I11 and the three-jaw chuck II 13 tightly push the die 12.

The 2 positioning through holes 16 arranged at the two ends of the die 12 are named as a positioning through hole A and a positioning through hole B respectively; the top of the square steel 6 is opposite to the positioning through hole B, a cable needing to be wound passes through the inner cavity of the square steel 6 from bottom to top and is wound on the roller 5, then a wire end of the cable is provided with a wiring terminal, passes through the positioning through hole B and then enters the inner cavity of the die 12 and is fixed on the inner wall of the die 12; thereby realizing the fixation of the end of the cable on the mold 12.

2) When the high-power motor 7 starts to work, the rotating shaft I of the spindle box I9, the rotating shaft II in the spindle box II 14 and the die 12 rotate coaxially and synchronously. The die 12 is driven by the three-jaw chuck I11 and the three-jaw chuck II 13 to rotate around the horizontal line direction. The low-power motor 1 is started simultaneously, the lead screw 2 is driven by the low-power motor 1 to rotate, the fixing rod 3 is driven by the sliding block 15 to move along the horizontal line direction, the cable is subjected to horizontal acting force of the mold 12 on the circumference of the cable and the action of the fixing rod 3, the cable can be wound on the mold 12 to move according to the parallelogram rule of force, namely, the cable can automatically wind the positioning through hole A from the positioning through hole B. The pitch of the windings is related to the rotational speed of the low power motor 1 and the high power motor 7.

The winding distance s is equal to the rotation speed (r/min) of the low-power motor 1 x the winding time (min) x the circumference (m) of the lead screw 2/[ the rotation speed (r/min) of the high-power motor 7 x the winding time (min) ].

Generally, the rotation speed of the small power motor 1 is greater than that of the large power motor 7. In actual work, the cable wire does not need to wind the whole die 12 completely, and only needs to wind partial cable wires at two ends of the die 12 to meet the requirement of connecting the pipe fitting and the pipeline, so that the rotating speed of the small-power motor 1 can be adjusted, the span of the distance between the middle cable wires of the die 12 is increased, and the cable wire material is saved.

After the winding is finished, the high-power motor 7 is turned off, the cable is cut off, a wiring terminal is arranged at the fracture of the cable, and the wiring terminal penetrates through the positioning through hole A and then enters the inner cavity of the mold 12 and is fixed on the inner wall of the mold 12.

The small-power motor 1 rotates reversely, so that the fixing rod 3 with the cable is driven to reset, namely, the top of the square steel 6 is restored to be opposite to the positioning through hole B. The low power motor 1 is switched off.

The hydraulic systems in the spindle box I9 and the spindle box II 14 also stop working, and at the moment, the die 12 is not in a tightly jacked state any more; the clamping jaws of the three-jaw chuck I11 and the three-jaw chuck II 13 are loosened, the mold 12 with the finished winding is taken down, and then the subsequent operation can be carried out according to the conventional prior art: and (4) finishing hot injection molding on an injection molding machine.

Finally, it is also noted that the above-mentioned lists merely illustrate a few specific embodiments of the invention. It is obvious that the invention is not limited to the above embodiments, but that many variations are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the present invention are to be considered within the scope of the invention.
