Description

Technical Field

[0001] The utility model relates to the technical field of cable manufacturing, in particular to a manufacturing production line of an aluminum alloy rubber sheathed cable. Background Art

[0002] At present, aluminum alloy conductors of aluminum alloy rubber sheathed cable products are mostly produced by wrapping, and the mold production method of rubber sheathed products is extrusion production, using cold feed rubber extruders. The rubber material production extrusion pressure is high. If there is no wrapping tape on the outside of the aluminum alloy conductor, the thrust of material extrusion acts entirely on the surface of the single wire of the aluminum alloy conductor. During the continuous production process, the single wire of the aluminum alloy conductor will continue to be stressed and slip. After a long production time, the single wire of the aluminum alloy conductor will slip out of the surface of the aluminum alloy conductor and be pulled to the back, causing production die jamming, abnormal equipment shutdown, and great quality risks. However, wrapping each reel of aluminum alloy conductor will occupy the wrapping machine for a long time. When the production volume of aluminum alloy rubber sheathed cables on site is relatively large, it is not conducive to the circulation of products in the workshop and affects production efficiency.

[0029] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved more clearly, the technical solutions of the present invention are further explained below with reference to the accompanying drawings and through specific implementation methods.

[0030] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Aluminum alloy rubber sheathed cable includes aluminum alloy conductor and rubber sheath. Aluminum alloy conductor is formed by merging three aluminum alloy monofilaments. Aluminum alloy rubber sheathed cable is produced by extrusion. During production, a rubber extruder is used to extrude the rubber sheath on the surface of the aluminum alloy conductor to form a rubber sheath. The extrusion temperature of rubber material is low, the material is hard, and the extrusion pressure is high. If the aluminum alloy conductor is not covered with a layer of tape, the monofilament of the aluminum alloy conductor will slip after being stressed during continuous production, causing the rubber extruder to jam and stop. Therefore, a tape needs to be set between the aluminum alloy conductor and the rubber sheath.

[0032] In the prior art, a wrapping machine is used to wrap the tape. However, in mass production, the wrapping machine will be occupied for a long time, causing the flow of other wrapped products in the production workshop to lag, affecting production efficiency.

[0033] In order to solve the above problems, Figure 1As shown, this embodiment provides a production line for manufacturing aluminum alloy rubber sheathed cables, and the production line for manufacturing aluminum alloy rubber sheathed cables includes a rubber extruder 1, a first unloading mechanism 2, a second unloading mechanism 3 and a longitudinal wrapping molding mechanism 4. The rubber extruder 1 is used to extrude rubber onto the surface of the aluminum alloy conductor 100 to form a rubber sheath. The first unloading mechanism 2 and the second unloading mechanism 3 are both arranged before the rubber extruder 1. The first unloading mechanism 2 is used to guide the aluminum alloy conductor 100, and the second unloading mechanism 3 is used to guide the wrapping tape 201. The longitudinal wrapping molding mechanism 4 is arranged before the head 11 of the rubber extruder 1. The longitudinal wrapping molding mechanism 4 is coaxially arranged with the head 11. The aluminum alloy conductor 100 guided by the first unloading mechanism 2 and the wrapping tape 201 guided by the second unloading mechanism 3 are jointly guided to the longitudinal wrapping molding mechanism 4 and then enter the head 11 after longitudinal wrapping molding. The rubber extruded by the head 11 acts on the wrapping tape 201, so that the rubber is wrapped around the aluminum alloy conductor 100 through the wrapping tape 201.

[0034] By arranging a longitudinal wrapping and molding mechanism 4 before the head 11 of the rubber extruder 1, the aluminum alloy conductor 100 discharged from the first unloading mechanism 2 and the wrapping tape 201 discharged from the second unloading mechanism 3 are jointly guided to the longitudinal wrapping and molding mechanism 4 and then enter the head 11 after longitudinal wrapping and molding. The extrusion force of the rubber extruded by the head 11 acts on the surface of the wrapping tape 201, so that the wrapping tape 201 is effectively attached to the surface of the aluminum alloy conductor 100, and the rubber sleeve is arranged on the surface of the wrapping tape 201, thereby producing an aluminum alloy rubber sheathed cable.

[0035] The wrapping tape 201 provided in this embodiment is a reinforced non-woven fabric wrapping tape. The inner side of the reinforced non-woven fabric wrapping tape is a polyester surface, which is relatively smooth, and the outer side is a non-woven fabric. The reinforced non-woven fabric wrapping tape and the aluminum alloy conductor 100 are directly entered into the rubber extruder 1 after being longitudinally wrapped and formed by the longitudinal wrapping and forming mechanism 4. The extrusion force of the rubber extruder 1 acts on the wrapping tape 201 on the surface of the aluminum alloy conductor 100, preventing the rubber from directly contacting the monofilaments of the aluminum alloy conductor 100 to reduce friction, and effectively avoiding the monofilaments of the aluminum alloy conductor 100 from sliding backwards after being subjected to a large force, thereby causing the problem of mold jamming.

[0036] Specifically, the longitudinal wrapping forming mechanism 4 includes a longitudinal wrapping forming mold 41, and the longitudinal wrapping forming mold 41 is provided with a forming hole along its axial direction. The forming hole is coaxially arranged with the feed hole of the machine head 11, and the forming hole is arranged as a conical hole, and the diameter of the conical hole gradually decreases from the feed end to the discharge end, and the minimum diameter of the conical hole is adapted to the diameter of the aluminum alloy conductor 100.

[0037] When entering the longitudinal wrapping forming die 41, the wrapping tape 201 can be located on any side of the circumference of the aluminum alloy conductor 100. The setting of the tapered hole allows the aluminum alloy conductor 100 and the wrapping tape 201 to enter the longitudinal wrapping forming die 41 smoothly, and then as the aperture of the forming hole gradually decreases, the wrapping tape 201 slowly wraps around the outer circumference of the aluminum alloy conductor 100, and finally when coming out of the longitudinal wrapping forming die 41, the wrapping tape 201 can tightly wrap around the surface of the aluminum alloy conductor 100. Since the wrapping tape 201 formed by the longitudinal wrapping forming mold 41 is not fixed on the surface of the aluminum alloy conductor 100, in order to prevent it from loosening before entering the machine head 11 to be coated with rubber, the forming hole and the feed hole of the machine head 11 are coaxially arranged, and the aluminum alloy conductor 100 discharged by the first discharge mechanism 2 and the wrapping tape 201 discharged by the second discharge mechanism 3 both have a certain tensioning force. After the wrapping tape 201 is tightly coated on the surface of the aluminum alloy conductor 100, it can smoothly enter the machine head 11 under the action of the original tensioning force, thereby avoiding the wrapping tape 201 being loose and unable to enter the machine head 11, affecting the coating of the rubber.

[0038] In order to realize the coaxiality of the longitudinal package forming mold 41 and the machine head 11, the longitudinal package forming mechanism 4 further includes a support assembly 42, on which the longitudinal package forming mold 41 is arranged, and the height of the support assembly 42 and the angle of the longitudinal package forming mold 41 on the support assembly 42 are adjustable. The longitudinal package forming mold 41 is supported by the support assembly 42, and the forming hole of the longitudinal package forming mold 41 is coaxially arranged with the feed hole of the machine head 11 by adjusting the height and angle of the longitudinal package forming mold 41.

[0039] Specifically, the support assembly 42 includes a support sleeve 421, a support shaft 422 and an adjusting member (not shown in the figure). The support shaft 422 is rotatably arranged in the support sleeve 421. The adjusting member cooperates with the support shaft 422 to drive the support shaft 422 to rotate so as to adjust the length of the support shaft 422 extending out of the support sleeve 421. The support sleeve 421 is fixed on the ground, and the support shaft 422 is rotatably arranged in the support sleeve 421. Since the longitudinal package forming mold 41 is close to the head 11, and the head 11 of the rubber extruder 1 needs to be cleaned regularly, in order not to affect the cleaning of the head 11, the support assembly 42 is set to a split structure. When cleaning the head 11, the length of the support shaft 422 extending out of the support sleeve 421 can be adjusted to leave operating space for cleaning the head 11.

[0040] In this embodiment, the adjusting member is a knob nut, which is threadedly matched with the support shaft 422. Two rotating rods are arranged in a circumferential direction of the knob nut. The knob nut is rotatably arranged at the end of the support sleeve 421 away from the ground. The knob nut is rotated by the two rotating rods to adjust the length of the support shaft 422 extending out of the support sleeve 421. Of course, in other embodiments, the adjusting member may not be arranged, and the support shaft 422 may be movably arranged in the support sleeve 421. The length of the support shaft 422 extending out of the support sleeve 421 is adjusted by moving the support shaft 422. After the adjustment is completed, the fixing bolt is passed through the support sleeve 421 to be fixedly connected to the support shaft 422.

[0041] Furthermore, a spring is arranged in the support sleeve 421 to support the support shaft 422. When adjusting the height, the support shaft 422 is pressed down to compress the spring; the support shaft 422 can also be stably supported by the elastic restoring force of the spring.

[0042] The support assembly 42 also includes a support seat 423, which is arranged at one end of the support shaft 422 away from the support sleeve 421, and the angle of the support seat 423 relative to the support shaft 422 is adjustable. The support seat 423 is provided with a mounting hole, and the longitudinal package forming mold 41 is arranged in the mounting hole, and the forming hole is arranged coaxially with the mounting hole. Since the outlet of the first discharge mechanism 2 for leading out the aluminum alloy conductor 100 is arranged higher than the head 11, the aluminum alloy conductor 100 is inclined downward when it is led out from the first discharge mechanism 2 to the longitudinal package forming mold 41. In order to achieve the coaxiality of the longitudinal package forming mold 41 and the head 11, the longitudinal package forming mold 41 is arranged on the support seat 423 with an adjustable angle.

[0043] Specifically, the support seat 423 includes two support plates, which are arranged in parallel and spaced apart, one of which is fixed to one end of the support shaft 422 and is inclined at a preset angle to the axis of the support shaft 422, and the other support plate is provided with a cylindrical structure, the inner hole of which is the mounting hole, and the longitudinal package forming mold 41 is arranged in the mounting hole and is fixedly connected to the cylindrical structure by fastening bolts. The two support plates are connected by two screws and fixed by nuts, and the angle of the support plate provided with the cylindrical structure can be fine-tuned by adjusting the screw connection position of the screw, thereby realizing the coaxial adjustment of the longitudinal package forming mold 41 and the machine head 11.

[0044] Furthermore, if Figure 2 and Figure 3As shown, the longitudinal package forming die 41 includes a die seat 411 and a die head 412, and the die head 412 is detachably connected to the die seat 411; the die seat 411 is provided with a first forming hole 4111 along its axial direction, and the die head 412 is provided with a second forming hole 4121 along its axial direction, and the first forming hole 4111 and the second forming hole 4121 are connected to form a forming hole, and the second forming hole 4121 is provided close to the die head 11, and the minimum diameter of the second forming hole 4121 is adapted to the diameter of the aluminum alloy conductor 100. A flange 4112 is provided at one end of the die seat 411 away from the die head 412, and a connecting hole 4113 is provided on the flange 4112, and a fastening bolt passes through the connecting hole 4113 and is screwed to the first threaded hole on the end surface of the cylindrical structure.

[0045] Since the outer diameters of the aluminum alloy conductors 100 of different types of aluminum alloy rubber sheathed cables are different, in order to adapt to different types of aluminum alloy rubber sheathed cables, the longitudinal wrapping forming mold 41 that is compatible with the outer diameter of the aluminum alloy conductor 100 should be replaced. In order to avoid multiple disassembly and assembly of the fastening bolts, the longitudinal wrapping forming mold 41 is set as a split structure in this embodiment. When manufacturing different types of aluminum alloy rubber sheathed cables, the size of the first forming hole 4111 of the mold seat 411 remains unchanged, and only the mold head 412 that is compatible with the outer diameter of the aluminum alloy conductor 100 of the aluminum alloy rubber sheathed cable needs to be replaced.

[0046] Specifically, the mold base 411 is threadedly connected to the mold head 412. A countersunk hole 4122 is provided at one end of the mold head 412 close to the mold base 411, and an internal thread is provided on the inner wall of the countersunk hole 4122. An external thread is provided at one end of the mold base 411 close to the mold head 412. The internal thread and the external thread cooperate to achieve the threaded connection between the mold base 411 and the mold head 412. When replacing the mold head 412, it only needs to screw the mold head 412 to achieve disassembly and assembly, which makes the replacement operation simpler and more efficient.

[0047] In this embodiment, the first unloading mechanism 2 is a wheeled traction machine, and the aluminum alloy conductor 100 is pulled out by the wheeled traction machine.

[0048] The second unloading mechanism 3 includes an unloading assembly 31 and a guide assembly 32. The tape roll 200 is arranged on the unloading assembly 31. One end of the tape 201 on the tape roll 200 is guided to the longitudinal wrapping forming mechanism 4 via the guide assembly 32. Specifically, the unloading assembly 31 includes a support column, a support rod and a limiter. Two support columns are arranged opposite to each other. The support rod is arranged between the two support columns. The tape roll 200 is rotatably arranged on the support rod. The limiters are arranged on the support rod and are located at both ends of the tape roll 200. The limiters are used to limit the axial movement of the tape roll 200 along the support rod.

[0049] In this embodiment, the limiting member includes two limiting discs, the limiting discs include a limiting disc, a connecting disc, and a through hole that passes through the limiting disc and the connecting disc. The limiting disc is sleeved on the support rod through the through hole and can move on the support rod. The outer diameter of the limiting disc is larger than the outer diameter of the connecting disc. A second threaded hole is arranged in the circumference of the connecting disc. When the limiting discs of the two limiting discs are respectively in contact with the two ends of the tape roll 200, the screws are screwed with the second threaded holes and in contact with the support rod to fix the limiting disc on the support rod. Such a setting can fix the tape roll 200 at the center of the support rod, avoid the tape roll 200 moving left and right on the support rod during the production process, affect the lead-out direction of the tape 201, and avoid the tape 201 being unable to be introduced into the longitudinal package forming mold 41 together with the aluminum alloy conductor 100 due to deviation in the lead-out direction.

[0050] The guide assembly 32 includes a plurality of guide wheels, one of which is arranged near the first unloading mechanism 2 and is located at one side of the discharge port of the first unloading mechanism 2, and the other guide wheels are arranged between the unloading assembly 31 and the first unloading mechanism 2, and between the first unloading mechanism 2 and the longitudinal wrapping molding mechanism 4. The wrapping tape roll 200 rotates on the support rod, and one end of the wrapping tape 201 is guided to one side of the aluminum alloy conductor 100 by the guide wheel near the first unloading mechanism 2, and is attached to the surface of the aluminum alloy conductor 100. As the aluminum alloy conductor 100 and the wrapping tape 201 are gradually led out, the aluminum alloy conductor 100 and the wrapping tape 201 enter the longitudinal wrapping molding die 41 for longitudinal wrapping molding, and then enter the machine head 11. The rubber extruded in the machine head 11 tightly wraps the wrapping tape 201 on the surface of the aluminum alloy conductor 100. The guide wheels between the unloading assembly 31 and the first unloading mechanism 2 , as well as the first unloading mechanism 2 and the longitudinal wrapping molding mechanism 4 , all guide the wrapping tape 201 , so that the wrapping tape 201 can enter the longitudinal wrapping molding die 41 together with the aluminum alloy conductor 100 .

[0051] In order to ensure that the wrapping tape 201 can enter the longitudinal wrapping forming die 41 together with the aluminum alloy conductor 100 and to ensure the wrapping density of the wrapping tape 201 on the surface of the aluminum alloy conductor 100, the distance between the wrapping tape 201 and the aluminum alloy conductor 100 before entering the longitudinal wrapping forming die 41 should not be too large. In this embodiment, the distance between the guide wheel close to the first unloading mechanism 2 and the aluminum alloy conductor 100 led out by the first unloading mechanism 2 is 10 cm to 20 cm.

[0052] The manufacturing production line of the aluminum alloy rubber sheathed cable provided in this embodiment, during production, firstly, the tape roll 200 is placed on the support rod, and after being adjusted to the center position of the support rod, the tape roll 200 is fixed by two limiting discs, and then one end of the tape 201 is guided by the guide wheel and led out to the vicinity of the first unloading mechanism 2, the first unloading mechanism 2 leads out the aluminum alloy conductor 100, the tape 201 is attached to the surface of the aluminum alloy conductor 100, and then the aluminum alloy conductor 100 together with the tape 201 is pulled into the longitudinal wrapping forming mold 41 and is ejected from the longitudinal wrapping forming mold 41. After the mold 41 is extended, it enters the machine head 11, and then the rubber extruder 1 is started. During the operation of the rubber extruder 1, a pulling force is generated on the aluminum alloy conductor 100 and the wrapping tape 201. The aluminum alloy conductor 100 and the wrapping tape 201 are continuously led out and enter the longitudinal wrapping forming mold 41 and then enter the machine head 11. The machine head 11 extrude rubber, and the thrust generated by the rubber extrusion acts on the wrapping tape 201 to prevent the rubber from directly contacting the single wire of the aluminum alloy conductor 100 to reduce friction, thereby avoiding the production jam caused by the single wire of the aluminum alloy conductor 100 sliding backward after being subjected to a large force. By improving the production line, the quality problem of aluminum alloy conductor 100 slipping and jamming in continuous production without wrapping tape 201 is solved, and at the same time, a wrapping process is saved, the productivity of the wrapping machine is liberated, the normal circulation of products is accelerated, and the production efficiency is improved.
