Description

Technical Field

[0001] The invention belongs to the technical field of cable twisting machines, and in particular relates to a production process of a household cable twisting machine. Background Art

[0002] The cable twisting is to stretch the conductors on multiple raw wire reels to a certain tension, and then twist the conductors together with a centering mechanism. Compared with a single conductor, the twisted cable has significantly improved flexibility and stability, and is easier to transport, install and lay. Currently, cable twisting is mostly done using a twisting machine.

[0003] When the existing cable twisting machine is working, due to the lack of suitable buffer devices, when the twisting machine encounters an emergency and needs to stop, the twisting machine will continue to rotate due to inertia, but the wire on the raw material reel will stop unwinding, resulting in the originally tensioned wire being broken due to the continued rotation of the twisting machine, thereby affecting the normal production of the cable. At the same time, the sudden stop of the twisting machine will also damage the transmission mechanism connected to the twisting machine, such as gears and belts, affecting the subsequent normal operation of the twisting machine.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

The braking principle of the caliper 12 is the same as the braking principle of the caliper 12 on the existing automobile, and its setting method is a technology known to technicians in the relevant field, and a hydraulic oil pipe 13 is connected to the side of the caliper 12 away from the support plate 3, and the bottom end of the hydraulic oil pipe 13 is connected to a hydraulic pump 14, and the hydraulic pump 14 is installed on the top of the base 1. A buffer assembly 15 is arranged at the bottom of the gear ring 10, and a centering mechanism 16 is arranged at one end of the drive shaft 2 close to the winch drum 8, and the centering mechanism 16 is vertically installed on the top of the base 1. A locking assembly 17 is installed on the support plate 3 close to the centering mechanism 16, and two reinforcement rods 20 are vertically fixedly connected between the two support plates 3, and the two reinforcement rods 20 are symmetrical about the drive shaft 2;

[0036] The specific process includes the following steps:

[0037] Step 1: Install the raw material reel 7 for producing the cable on the mounting plate 6;

[0038] Step 2: Pass the wire on the wire drum through the stranding drum 8 and introduce it into the centering mechanism 16;

[0039] Step 3: Start the driving shaft 2 to drive the twisting drum 8 to rotate, and then cooperate with the centering mechanism 16 to twist the multiple wires into a cable.

[0040] The buffer assembly 15 includes two limit rods 151, which are slidably inserted between the two sliders 4, and the two ends of the limit rod 151 are fixedly connected to the inner walls of the corresponding two sides of the slide groove, and a buffer spring 152 is sleeved on the limit rod 151. The buffer spring 152 is located between the two sliders 4, and one end of the buffer spring 152 is fixedly connected to the slider 4 away from the centering mechanism 16, and the other end of the buffer spring 152 is fixedly connected to a limit ring 153, and the limit ring 153 is fixedly sleeved on the limit rod 151. A fixed shaft 154 is arranged in parallel between the two limit rods 151, and the end of the fixed shaft 154 close to the centering mechanism 16 is connected to a ball screw 155. The ball screw 155 is threadedly sleeved with a sleeve 156, and the ends of the ball screw 155 and the fixed shaft 154 that are separated are both rotatably connected with a first fixed block, and the first fixed block is fixedly connected to the top of the base 1, and the sleeve 156 is fixedly inserted on the support plate 3 close to the centering mechanism 16, and the fixed shaft 154 is sleeved with a transmission component 18 at a position opposite to another support plate 3, and a notch is penetrated through the position of the support plate 3 away from the centering mechanism 16 and opposite to the transmission component 18, and the transmission component 18 is inserted through the notch, and the maximum rotation angle of the gear ring 10 driven by the brake disc 9 is less than one circle, and when the gear ring 10 reaches the maximum rotation angle, the buffer spring 152 also reaches the maximum compression amount;

[0041] The transmission assembly 18 includes a columnar gear 181, which is rotatably sleeved on the fixed shaft 154, and the top of the gear 181 is meshed with the bottom of the gear ring 10. Both ends of the gear 181 are provided with fixed plates 182, and the fixed plates 182 are fixedly sleeved on the fixed shaft 154. Two arc-shaped limit grooves are provided on the side of the fixed plate 182 opposite to the gear 181, and a limit block 183 is slidably installed in the limit groove. The limit block 183 is fixedly connected to the end of the gear 181, and an arc rod 184 is inserted and slidably penetrated between the two ends of the limit block 183. A return spring 185 is sleeved on the arc rod 184, and the two return springs 185 are rotationally symmetrical about the center of the fixed plate 182, and the two ends of the return spring 185 are respectively fixedly connected to the corresponding limit block 183 and the inner wall of the limit groove;

[0042] When the wire twisting machine is working normally, the gear ring 10 is restricted by the gear 181. Therefore, during the rotation of the brake disc 9, the gear ring 10 and the swivel 11 can remain stationary. When the wire twisting machine needs to be stopped urgently, as the hydraulic pump 14 works, the hydraulic pump 14 can pump hydraulic oil into the caliper 12 through the hydraulic oil pipe 13. At this time, as the hydraulic oil enters the caliper 12, the brake pad in the caliper 12 can be tightly attached to the brake disc 9, so that the gear ring 10 and the brake disc 9 are connected as a whole through friction. At this time, when the wire twisting machine drives the brake disc 9 to continue to rotate under the action of inertia, the gear ring 10 can drive the gear 181 to rotate through the teeth on its surface At this time, since the gear 181 is suddenly subjected to the force from the gear ring 10 in a stationary state, the instantaneous force on the gear 181 is very large, which may cause the gear 181 and the teeth on the gear ring 10 to break. However, due to the presence of the return spring 185, when the gear 181 is subjected to the force of the gear ring 10 and starts to rotate, the gear 181 can squeeze the return spring 185 through the limit block 183. As the return spring 185 is gradually compressed, the instantaneous force of the gear ring 10 on the gear 181 can be partially converted into the elastic force of the return spring 185, thereby protecting the gear 181 and the gear ring 10.

[0043] As the return spring 185 is further compressed, the force of the return spring 185 on the limit groove gradually increases. When the force of the return spring 185 on the limit groove is greater than the thrust of the buffer spring 152 and the slider 4, the gear ring 10 can drive the fixed shaft 154 and the ball screw 155 to rotate through the gear 181. As the ball screw 155 rotates, the ball screw 155 can drive the slider 4 connected to the shaft sleeve 156 to move through the shaft sleeve 156. As the slider 4 moves, the slider 4 can drive another support plate 3 and the slider 4 adjacent to the buffer spring 152 to move through the support plate 3, the reinforcement rod 20 and the drive shaft 2 at its top. As the slider 4 connected to the buffer spring 152 moves, the wire twister also moves with the slider 4 towards the centering mechanism 16. Therefore, when the wire twister continues to rotate, the distance between the wire twister and the centering mechanism 16 is shortened to prevent the wire from being broken.

[0044] In addition, during the movement of the slider 4, the slider 4 connected to the buffer spring 152 can gradually compress the buffer spring 152, thereby converting the kinetic energy of the wire twisting machine into the internal energy of the buffer spring 152, thereby reducing the influence of inertia on the transmission mechanism of the wire twisting machine during the emergency braking of the wire twisting machine. As the buffer spring 152 is continuously compressed, the reaction force of the buffer spring 152 on the slider 4 gradually increases, thereby allowing the slider 4 to gradually stop. As the slider 4 stops, the wire twisting machine can also slowly stop. The locking assembly 17 can lock the current position of the wire twisting machine, thereby preventing the stopped twisting cable from being broken when the wire twisting machine is reset under the action of the buffer spring 152, thereby ensuring the smooth progress of subsequent cable twisting operations.

[0045] like Figures 1 to 7 As shown, the locking assembly 17 includes a hanging plate 171, which is hinged on the support plate 3 opposite to the centering mechanism 16. The hanging plate 171 is located on the side of the support plate 3 close to the centering mechanism 16, and the bottom of the hanging plate 171 close to the centering mechanism 16 protrudes downward, and a stopper 172 is horizontally arranged at the bottom of the hanging plate 171, and the stopper 172 is fixedly connected to the corresponding support plate 3, and in the initial state, the hanging plate 171 can maintain a horizontal state under the support of the stopper 172, and a hook plate 173 is horizontally slidably inserted on the inner wall of the side opposite to the hanging plate 171 of the slide groove, and the top of the hook plate 173 close to the side of the hanging plate 171 protrudes upward, and the downwardly protruding part of the hanging plate 171 and the downwardly protruding part of the hook plate 173 are both inclined on the opposite sides, and the inclined surface is inclined from top to bottom in the direction close to the support plate 3. The plate 173 and the protruding part of the hanging plate 171 can be hung together, and the bottom of the hook plate 173 is fixedly connected with a second fixed block, and the second fixed block is horizontally and vertically fixedly connected with a telescopic rod 174 on one side close to the hanging plate 171, and a shock-absorbing spring 175 is sleeved on the telescopic rod 174, and one end of the telescopic rod 174 close to the hanging plate 171 is fixedly connected with a positioning block 176, and the positioning block 176 is fixedly connected to the bottom of the slide groove, and the two ends of the shock-absorbing spring 175 are respectively fixedly connected to the second fixed block and the positioning block 176, and the free end of the hanging plate 171 is fixedly connected with a U-shaped pull rod 19, and the pull rod 19 is sleeved on the outside of the ball screw 155, and the length of the hanging plate 171 and the hook plate 173 is equal to the maximum compression of the buffer spring 152, and the distance between the hanging plate 171 and the opposite side of the hook plate 173 is less than the maximum compression of the buffer spring 152;

[0046] By providing the locking assembly 17, when the support plate 3 moves toward the hook plate 173 under the cooperation of the ball screw 155 and the shaft sleeve 156, the hanging plate 171 also gradually approaches the hook plate 173. When the protruding portion at the bottom of the hanging plate 171 contacts the protruding portion at the top of the hook plate 173, the protruding portion at the bottom of the hanging plate 171 can deflect upward under the pushing of the protruding portion at the bottom of the hook plate 173. As the support plate 3 continues to move, when the protruding portion at the bottom of the hanging plate 171 is staggered with the protruding portion at the top of the hook plate 173, the hanging plate 171 can deflect downward under the action of gravity and restore to a horizontal state. When the wire twisting machine stops rotating, the slider 4 also stops continuing to move in the direction close to the centering mechanism 16. At this time, since the buffer spring 152 is in a force storage state, as the buffer spring 152 gradually extends, the slider 4 can drive the support plate 3 to move away from the centering mechanism 16 under the action of the buffer spring 152. When the support plate 3 is moved further away from the centering mechanism 16, the ball screw 155 can be reversed, and the hanging plate 171 can be moved along with the support plate 3 in the direction away from the centering mechanism 16. When the protruding portion at the bottom of the hanging plate 171 contacts the protruding portion at the top of the hook plate 173, the hanging plate 171 and the hook plate 173 can be hooked together, and as the support plate 3 continues to move, the second fixing block can squeeze the telescopic rod 174 and the shock absorbing spring 175 driven by the hook plate 173, and as the shock absorbing spring 175 is gradually compressed, the shock absorbing spring 175 can convert the collision force of the hanging plate 171 on the hook plate 173 into the elastic potential energy of the shock absorbing spring 175, thereby reducing the collision force of the hanging plate 171 on the hook plate 173. When the telescopic rod 174 is fully compressed, the entire wire twisting machine can also stop immediately under the restricting effect of the hook plate 173 on the hanging plate 171, thereby preventing the stopped twisted cable from being broken due to the resetting of the wire twisting machine.

[0047] When the emergency situation is resolved, the wire twisting machine is started first. When the wire twisting machine is running stably, the hanging plate 171 is pulled upward by the pull rod 19, so that the hook plate 173 can release the restriction on the hanging plate 171. Then, as the buffer spring 152 gradually extends, the running wire twisting machine can slowly return to its original position under the action of the buffer spring 152.

[0048] In addition, the distance between the hanging plate 171 and the hook plate 173 on the opposite side is set to be smaller than the maximum compression of the buffer spring 152, mainly because the inertia of the wire twister is related to the mass of the wire twister. In the initial working stage of the wire twister, since there are more wires on the raw material reel 7, the overall mass of the wire twister is also larger at this time. Therefore, when the wire twister is suddenly braked, the inertia of the wire twister is also larger, so that the slider 4 can move a longer distance under the action of larger inertia. In the later working stage of the wire twister, the wires on the raw material reel 7 are reduced, so the mass of the wire twister is also reduced. Therefore, when the wire twister is suddenly braked, the inertia of the wire twister is also smaller, so that the slider 4 can move a shorter distance under the action of smaller inertia. At this time, since the distance between the hanging plate 171 and the hook plate 173 on the opposite side is smaller than the maximum compression of the buffer spring 152, it is ensured that when the slider 4 moves a smaller distance, the hook plate 173 can also be hung with the hanging plate 171, thereby locking the current position of the wire twister.

[0049] like Figure 6 As shown, a protective rubber pad 21 is fixedly connected to the inner wall of the slide groove close to the gear 181, and in the initial state, the protective rubber pad 21 is kept in close contact with the corresponding slider 4;

[0050] By providing the protective rubber pad 21, when the slider 4 connected to the buffer spring 152 is gradually reset under the action of the buffer spring 152, the protective rubber pad 21 can protect and reduce shock to the slider 4, thereby reducing the collision force between the slider 4 and the inner wall of the slide groove.

[0051] like Figure 1 As shown, protective covers 22 are provided on both sides of the wire twisting machine, and the protective covers 22 are hinged to the top of the base 1, and the protective covers 22 are hollow in design;

[0052] During the operation of the wire twisting machine, the protective cover 22 can be used to protect the wire twisting machine, thereby preventing outsiders or objects from contacting the running wire twisting machine, thereby ensuring the safe production of the wire twisting machine.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
