DETAILED DESCRIPTION

[0029] To make the purpose, technical scheme and advantages of the embodiments of the present disclosure clearer, the technical scheme of the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without any inventive effort fall within the protection scope of the present disclosure.

[0030] Embodiment 1, please refer to Figures 1-5 A copper wire drawing unit with cooling device, comprising a device body 1, a pair of conical rollers is arranged on the device body 1, a wire drawing die holder 2 is arranged between the pair of conical rollers, a plurality of eyelet dies 3 are arranged on the wire drawing die holder 2, copper wires are arranged through the eyelet dies 3, a spraying system is further arranged on the wire drawing die holder 2, the wire drawing die holder 2 comprises a frame body 21 and a plurality of groups of support blocks 22 arranged equidistantly on the frame body 21, a placing groove is formed between each group of support blocks 22, the eyelet dies 3 are arranged in the placing groove, a lubricating part 4 is arranged on the support blocks 22, the lubricating part 4 comprises a spray head arranged on the side end of the support block 22, a trigger part 5 is arranged on the side end of the support block 22, the trigger part 5 comprises a pressure sensor 55 fixedly connected to the other side end of the support block 22, an elastic member 54 is arranged between the pressure sensor 55 and the eyelet die 3, the trigger part 5 detects the pressure applied by the eyelet die 3 during the wire drawing process through the pressure sensor 55, and opens the spray head when the set pressure is reached to lubricate the eyelet die 3.

[0031] The spraying system comprises a water spraying pipe, the water outlet of the water spraying pipe is arranged obliquely, the oblique angle is 10-30 degrees, and the water outlet is aligned with the eyelet die 3 for cooling the copper wires.

[0032] Initially, the staff will be fine one end of the copper wire, and through the first line eye mold 3, the case with 12 eye mold as an example, that is, there are 12 line eye mold 3, and the line eye decreases in turn, therefore, the staff need to follow the order of copper wire in turn through the 12 line eye mold 3, and also in turn around a pair of conical roller line groove, finally the copper wire end connected to the winding roller 11.

[0033] Specifically, the device body 1 is also provided with a wire roller 9 and a fixed pulley 10, the fixed pulley 10 is provided with a driving guide rail, which is responsible for pushing the fixed pulley 10 reciprocating motion according to the program, the fixed pulley 10 is provided with a winding roller 11 outside, so that the copper wire can be closely wound on the winding roller 11.

[0034] When the actual start of the wire drawing, the line eye mold 3 is forced to resist on the support block 22, when the copper wire is subjected to a larger pulling force, the force is converted to the line eye mold 3 on the support block 22, by setting the elastic element 54 and the pressure sensor 55 between the support block 22 and the line eye mold 3, the pressure data can be obtained in time, the elastic element 54 is a pressure spring, which will be forced to apply a support force to both ends after being subjected to pressure, and the pressure sensor 55 can obtain the support force data, the pressure sensor 55 transmits the data to the controller, the controller opens the nozzle, the nozzle can select the atomizing nozzle, the nozzle sprays the lubricating liquid in the corresponding line eye of the line eye mold 3, reduces the friction at this place, makes the wire drawing process more smooth, also effectively reduces the risk of copper wire breakage.

[0035] Specifically, the pressure sensor 55 can also control the amount of lubricating liquid sprayed by the nozzle according to the pressure data, so that the greater the pressure, the more lubricating liquid is sprayed.

[0036] The pressure spring can also have the effect of resetting subsequently, so that when the friction generated by the copper wire on the line eye mold 3 returns to the initial value, it can be automatically reset.

[0037] The trigger component 5 further comprises an arc-shaped frame 51 fixedly connected to the top surface of the placement groove, the top of the arc-shaped frame 51 is fixedly connected with a first magnetic block 52, and the side surface of the arc-shaped frame 51 is slidably connected with a second magnetic block 53, the line eye mold 3 is initially fixed in position by the attraction between the first magnetic block 52 and the second magnetic block 53.

[0038] Initially, the first magnetic block 52 and the second magnetic block 53 attract each other so that the line eye mold 3 cannot approach the support block 22, when the pressure gradually increases and breaks through the magnetic force of the first magnetic block 52 and the second magnetic block 53, the pressure spring will be extruded, so that the lubricating oil begins to be sprayed.

[0039] The embodiment 2 is different from the embodiment 1 in that the following technical feature is added: the driving component 6 is arranged on the line eye mold 3, the driving component 6 comprises a driving piece 61, the bottom of the driving piece 61 is fixedly connected with an elastic layer 62, the elastic layer 62 is initially overlaid on the line eye mold 3, and the driving component 6 is responsible for driving the driving piece 61 to rotate when reaching a set pressure, so that the corresponding line eye mold 3 rotates and the stress area of the line eye mold 3 is switched.

[0040] The driving component 6 comprises a driving motor 63, the output end of the driving motor 63 is fixedly connected with a driving shaft 64, and the driving shaft 64 is in transmission connection with the driving piece 61, and in this embodiment, the driving shaft 64 is fixedly connected with the driving piece 61.

[0041] The driving motor 63 is in electrical signal connection with the controller, and when the driving motor 63 receives the set data of the pressure sensor 55, the driving motor 63 is passively started and drives the driving piece 61 and the elastic layer 62 to rotate, the elastic layer 62 is partially pressed on the line eye mold 3, the contact area with the line eye mold 3 is increased, the elastic layer 62 is made of elastic silica gel material, the elastic force is large enough, so that when the elastic layer 62 rotates, the line eye mold 3 can be provided with sufficient horizontal tangential force, so that the line eye mold 3 is forced to rotate by a set angle and the stress area of the line eye mold 3 is changed.

[0042] In actual use, the track of the copper wire movement is not necessarily horizontal movement, or is not strictly moved at the same horizontal height, so that the stress on the line eye of the line eye mold 3 is not uniform, and therefore, the stress area needs to be replaced.

[0043] In addition, sometimes the copper wire may be stuck, and there are two reasons for this, one is that the surface of the copper wire is rough, and the other is that the line eye of the line eye mold 3 is rough and the copper wire cannot slide smoothly, and at this time, rotating the line eye mold 3 can help the copper wire to smoothly pass through the line eye mold 3.

[0044] Of course, rotating the line eye mold 3 can also make the lubricating liquid spread in a wider area and improve the lubricating effect.

[0045] The embodiment 3 is different from the embodiment 2 in that the following technical feature is added: referring to Figures 6-8 , the water blocking component 7 is further arranged on the support block 22, the water blocking component 7 comprises a support plate 71, the support plate 71 is rotatably connected with a water blocking plate 72, the water blocking plate 72 is fixedly connected with a rotating shaft, a spring reel is sleeved on the rotating shaft, one end of the spring reel is fixedly connected with the rotating shaft, and the other end of the spring reel is fixedly connected with the support plate 71, and the water blocking plate 72 is responsible for driving the water blocking plate 72 to rotate to a horizontal state after the pressure sensor 55 detects a set pressure, and after the force is unloaded, the water blocking plate 72 can be reset under the action of the spring reel.

[0046] In the embodiment, the driving shaft 64 is rotationally connected with the driving member 61.

[0047] In the further provided embodiment of the application, the water blocking component 7 further comprises a traction member 73 fixedly connected with the water blocking plate 72, the water blocking plate 72 is automatically rotated under gravity when the end of the traction member 73 is pulled, and a limiting plate is arranged on the supporting plate 71, which is responsible for supporting the water blocking plate 72 after rotation.

[0048] Further, a rope winding roller is fixedly connected with the driving shaft 64, and the other end of the traction member 73 is fixedly wound on the rope winding roller, and the driving shaft 64 moves the end of the traction member 73 when rotating.

[0049] Preferably, a rope winding rod 74 is fixedly connected with the rope winding roller, so that when the rope winding roller rotates, the rope is wound (hung) on the rope winding rod and spirally wound on the rope winding roller, achieving the purpose of winding.

[0050] Further, the driving shaft 64 is sleeved with an alternate rotating component 8, the alternate rotating component 8 comprises an annular frame 81, thread grooves 82 are formed on both sides of the annular frame 81, a first driven rod 84 is slidably connected with the outer wall of the rope winding roller, a telescopic rod 86 is fixedly connected with the driving shaft 64, a compression spring is arranged in the telescopic rod 86, a poking rod 83 is fixedly connected with the top end of the telescopic rod 86, and a second driven rod 85 is fixedly connected with the side end of the driving member 61, the poking rod 83 sequentially touches the first driven rod 84 and the second driven rod 85 when rotating.

[0051] Specifically, an arc-shaped groove is formed on the rope winding roller, a sliding block is arranged in the arc-shaped groove, the sliding block is fixedly connected with the first driven rod 84, a reset spring is fixedly connected between the sliding block and the arc-shaped groove, an elastic block is further arranged in the arc-shaped groove, a clamping groove is formed on the side end of the sliding block, the elastic block is initially clamped with the clamping groove of the sliding block, and the elastic force of the reset spring is greater than the elastic force of the clockwork, so that the first driven rod 84 and the rope winding roller can be rotated by the elastic force of the reset spring at the beginning.

[0052] As can be seen from the embodiment 1, the device body 1 is provided with a spraying system, the spraying system sprays the line eye mold 3 and the copper wire, the purpose is to cool them at any time, avoiding deformation of the copper wire due to heat generated during friction.

[0053] When the driving motor 63 is started due to detection of the set data by the pressure sensor 55, the traction member 73 will be pulled, and once the end of the traction member 73 is stressed, the water blocking plate 72 will automatically fall to protect the upper part of the line eye mold 3, which can prevent the cooling water from falling and washing away the lubricating liquid.

[0054] When the pressure is recovered, the driving motor 63 is reversed, and the first bevel gear and the second bevel gear are engaged, so that the driven shaft and the rotating shaft are synchronously rotated, so that the baffle 72 can be rotated to the vertical state, and when the lubricating liquid is not sprayed to the eyelet mold 3, the cooling of the eyelet mold 3 is not affected, so that the device can be normally used.

[0055] Working process: the driving shaft 64 rotates with the telescopic rod 86, and the driving rod 83 of the telescopic rod 86 starts to drive in the threaded groove 82, and initially the driving rod 83 is in contact with the first driven rod 84 and rotates the first driven rod 84 and the rope winding roller, so that the rope winding roller winds the traction member 73, and pulls the baffle 72 to rotate downward, after rotating 2-3 turns, the first driven rod 84 starts to rotate relative to the rope winding roller, at this time the baffle 72 is in a horizontal state, then the driving shaft 64 continues to rotate and is in contact with the second driven rod 85 and rotates the driving member 61, finally the same effect of rotating the eyelet mold 3 by several angles (60-180 degrees) is achieved, when reversely rotating, the position of the driving member 61 is fixed, the driving rod 83 is no longer in contact with the second driven rod 85, and the first driven rod 84 is reset under the action of the reset spring, finally, under the action of the clockwork winding, the baffle 72 is reset.

[0056] The foregoing merely describes some exemplary embodiments of the present application by way of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art.
