Description

Technical Field

[0001] The utility model relates to the technical field of frame-type stranding machines, and in particular to a frame-type stranding machine for power conductors. Background Art

[0002] The frame-type stranding machine is a professional mechanical equipment used in the wire and cable industry. It is mainly used to manufacture stranded cores for various types of power cables, communication cables, and other types of cables. The frame-type stranding machine usually has a rotating stranding cage with multiple spools evenly distributed around the axis. Before stranding, the end of the wire on the spool needs to be pulled to the wiring hole at one end of the stranding cage.

[0003] At present, the above process is usually carried out by manual wiring. When the wire diameter is large and the wire material is hard, the wiring operation also needs to be assisted by tools such as hydraulic pliers and winders. The operation is relatively cumbersome, which has an adverse effect on the overall operating efficiency of the frame stranding machine. Utility Model Content

[0007] frame;

[0008] A rotating frame, the rotating frame is rotatably arranged on the frame;

[0009] Clamping mechanism; the clamping mechanism comprises,

[0010] A screw rod, the screw rod is rotatably arranged on the rotating frame, and the screw rod is arranged along a direction parallel to the axis of the rotating frame;

[0011] A slider, wherein the screw rod is threadably matched with the slider;

[0012] A clamping wheel, the clamping wheel is rotatably arranged on the slider, and the gear teeth of the clamping wheel are used to abut against the wire on the rotating frame;

[0013] A ratchet pawl is rotatably arranged on the sliding block and abuts against the gear teeth of the pressing wheel.

[0014] As a further technical solution, a driving mechanism is further included, wherein the driving mechanism is arranged on the frame, and a power output end of the driving mechanism is connected to the rotating frame for driving the rotating frame to rotate around its own axis.

[0015] As a further technical solution, the driving mechanism includes:

[0016] A motor, wherein the motor is arranged on the frame;

[0017] A reducer, wherein a power output end of the reducer is connected to the rotating frame, and a power input end of the reducer is connected to the main shaft of the motor.

[0018] As a further technical solution, the edge of the teeth of the clamping wheel has a concave portion, and the concave portion fits with the wire on the rotating frame.

[0019] As a further technical solution, the edge of the sliding block has a guide portion for guiding the wire on the rotating frame to the concave portion.

[0025] The working principle and beneficial effects of the utility model are:

[0026] In the utility model, when the spool of the electric power conductor is fixed on the rotating frame, the end of the wire will slide into the narrow gap between the clamping wheel and the slider under the action of the thrust. At this time, the slider slides along the axial direction of the rotating frame under the driving action of the screw rod. Since the clamping wheel is blocked by the ratchet, the clamping wheel will not rotate due to the friction between the wire and the teeth of the clamping wheel, and the end of the wire will move toward the end of the rotating frame under the traction of the friction force, thereby realizing the function of automatic wiring. After the wiring is completed, when the wire is pulled out from one end of the rotating frame, the direction of the friction force generated by the wire on the clamping wheel causes the clamping wheel to rotate around the direction not restricted by the ratchet, so the clamping mechanism will not hinder the process of pulling the wire out of the rotating frame, and therefore will not affect the subsequent wire stranding process. Compared with the wiring method of the prior art, the wiring operation steps are simplified, the degree of automation is higher, and the production efficiency of the frame-type stranding machine is improved.

[0036] Reference Figure 1-Figure 3 A frame-type stranding machine for power conductors comprises: a frame 1; a rotating frame 2, which is rotatably arranged on the frame 1; a clamping mechanism 4; the clamping mechanism 4 comprises a screw rod 41, which is rotatably arranged on the rotating frame 2 and is arranged in a direction parallel to the axis of the rotating frame 2; a slider 42, the screw rod 41 and the slider 42 are threadedly matched; a clamping wheel 43, which is rotatably arranged on the slider 42, and the gear teeth of the clamping wheel 43 are used to abut against the wire on the rotating frame 2; a ratchet 44, which is rotatably arranged on the slider 42 and abuts against the gear teeth of the clamping wheel 43.

[0037] In this embodiment, a frame-type stranding machine for power conductors includes a frame 1, a rotating frame 2 and a clamping mechanism 4. Among them, the frame 1 can be a metal frame composed of hollow square steel welded together, and the frame 1 is fixedly installed on the horizontal ground by a plurality of anchor bolts. The rotating frame 2 is a metal frame made of metal material, and the rotating frame 2 is rotatably arranged on the frame 1, and the rotating frame 2 can rotate around its own axis direction. The clamping mechanism 4 includes a screw 41, a slider 42, a clamping wheel 43 and a ratchet 44. The screw 41 is rotatably arranged on the rotating frame 2, and the axial direction of the screw 41 is parallel to the axial direction of the rotating frame 2. The screw 41 is inserted into the slider 42 and is threadedly matched with the slider 42. The rotation of the screw 41 can push the slider 42 to slide along the axial direction of the rotating frame 2. The clamping wheel 43 can be a ratchet rotatably arranged on the slider 42. The ratchet 44 is rotatably arranged on the slider 42, and the ratchet 44 abuts against the gear teeth of the clamping wheel 43, limiting the rotation direction of the clamping wheel 43 so that it can only rotate in one direction. The gear teeth of the clamping wheel 43 abut against the electric wire wire installed on the rotating frame 2. When the electric wire spool is fixed on the rotating frame 2, the end of the wire will slide into the slit between the clamping wheel 43 and the slider 42 under the action of the thrust. At this time, the slider 42 slides along the axial direction of the rotating frame 2 under the driving action of the screw rod 41. Since the clamping wheel 43 is blocked by the ratchet 44, the clamping wheel 43 will not rotate due to the friction between the wire and the gear teeth of the clamping wheel 43, and the end of the wire will move toward the end of the rotating frame 2 under the traction of the friction, thereby realizing the function of automatic wiring. After the wiring is completed, when the wire is pulled out from one end of the rotating frame 2, the friction force generated by the wire on the clamping wheel 43 causes the clamping wheel 43 to rotate in a direction not restricted by the ratchet 44, so the clamping mechanism 4 will not hinder the process of pulling the wire out of the rotating frame 2, and therefore will not affect the subsequent wire twisting process. Compared with the wiring method of the prior art, the wiring operation steps are simplified, the degree of automation is higher, and the production efficiency of the frame twisting machine is improved.

[0038] Furthermore, it also includes a driving mechanism 3, which is arranged on the frame 1, and a power output end of the driving mechanism 3 is connected to the rotating frame 2 for driving the rotating frame 2 to rotate around its own axis.

[0039] In this embodiment, the power output end of the driving mechanism 3 is connected to the rotating shaft of the rotating frame 2, and the driving mechanism 3 can drive the rotating frame 2 to rotate around its own axis, thereby realizing the wire twisting function.

[0040] Furthermore, the driving mechanism 3 includes: a motor 31 , which is arranged on the frame 1 ; a reducer 32 , whose power output end is connected to the rotating frame 2 , and whose power input end is connected to the main shaft of the motor 31 .

[0041] In this embodiment, the power output shaft of the motor 31 in the driving mechanism 3 is connected to the power input end of the reducer 32, and the motor 31 can drive the reducer 32 to rotate. The power output end of the reducer 32 is connected to the rotating shaft of the rotating frame 2, and the torque of the motor 31 can be transmitted to the rotating frame 2.

[0042] Furthermore, the tooth edge of the pressing wheel 43 has a concave portion 431 , and the concave portion 431 fits with the wire on the rotating frame 2 .

[0043] In this embodiment, the concave portion 431 structure of the edge of the teeth of the clamping wheel 43 fits with the wire on the rotating frame 2. The structure of the concave portion 431 can increase the contact area between the teeth of the clamping wheel 43 and the wire, and reduce the possibility of slippage between the clamping wheel 43 and the wire.

[0044] Furthermore, the edge of the slider 42 has a guide portion 421 for guiding the wire on the rotating frame 2 to the concave portion 431 .

[0045] In this embodiment, a guide portion 421 is provided on the edge of the slider 42. The guide portion 421 is an inclined plane with an acute angle to the horizontal plane, which guides the wire and can guide the end of the wire to the slit between the concave portion 431 of the clamping wheel 43 and the slider 42 for clamping.

[0046] Furthermore, it also includes a guide rod 5 , which is arranged parallel to the screw rod 41 , and a slider 42 is slidably arranged on the guide rod 5 .

[0047] In this embodiment, the guide rod 5 arranged parallel to the screw rod 41 is passed through the slider 42, and the slider 42 is slidably arranged on the guide rod 5. When the slider 42 slides relative to the rotating frame 2 under the driving action of the screw rod 41, the guide rod 5 guides the slider 42 to prevent the slider from rotating with the screw rod 41, thereby improving the stability of the slider 42 during the sliding process.

[0048] Furthermore, it also includes a protection plate 6 , which is arranged outside the rotating frame 2 .

[0049] In this embodiment, the protection plate 6 installed on the outer side of the rotating frame 2 can prevent people from contacting the rotating part of the rotating frame 2, thereby protecting the people.

[0050] Furthermore, it also includes ribs 7 which are symmetrically arranged on the rotating frame 2 .

[0051] In this embodiment, the ribs 7 symmetrically mounted on the rotating frame 2 can increase the mechanical strength and bearing capacity of the rotating frame 2 and prevent the rotating frame 2 from deforming under heavy load conditions.

[0052] Furthermore, it also includes bearings 8 , which are sleeved on both ends of the rotating frame 2 .

[0053] In this embodiment, the bearings 8 sleeved on both ends of the rotating frame 2 can reduce the contact friction between the rotating frame 2 and the frame 1, and reduce the resistance that the rotating frame 2 needs to overcome when rotating.

[0054] Furthermore, the clamping mechanism 4 is an electric clamp, and the opening of the electric clamp points in a direction away from the rotating frame 2 .

[0055] In this embodiment, the clamping mechanism 4 uses an electric clamp, which has a better clamping and fixing effect on soft special-shaped wires and can play a better role in special working conditions where the cross-sectional shape of the wire is irregular.
