Description

Technical Field

[0001] The utility model relates to the technical field of special-shaped molds, in particular to a low-resistance special-shaped conductor wheel pressing type mold. Background Art

[0002] Today's medium and low voltage multi-core cables generally use special-shaped compressed conductors. This shape of conductor reduces the gap between single wires and increases the filling factor of the stranded wire. After extruded insulation, the cables are twisted into a round shape. The gap between the insulated cores is greatly reduced compared to the round cores, which reduces the amount of filling material used and the outer diameter of the cable core, ultimately reducing costs.

[0003] The patent application document with publication number CN111863346B discloses a wheel-pressing mold for special-shaped conductors for cables. The device can not only press the twisted wire harness into a special-shaped conductor of a specific shape, but also process the burrs of the special-shaped conductor after it is pressed and formed through a channel, thereby eliminating the need for a subsequent deburring structure, improving processing efficiency, reducing processing costs, and increasing practicality.

[0004] Although the above device is good, in actual use, in order to prevent the axial movement of the rolling wheel, a clamping plate is set on the side of the rolling wheel, and the clamping plate is pressed on the side of the rolling wheel. The clamping plate is pressed on the side of the rolling wheel to increase the friction between the clamping plate and the rolling wheel. When the rolling wheel rotates, the large friction will cause the rolling wheel and the clamping plate to wear more severely, shortening their service life. At the same time, the large friction will also reduce the efficiency of the rolling wheel rotation and increase energy consumption. In addition, the large friction will also generate a large amount of heat and noise during the rotation process of the rolling wheel. Utility Model Content

[0029] A low-resistance special-shaped conductor wheel pressing die according to an embodiment of the utility model will be described below in conjunction with the accompanying drawings.

[0030] like Figure 1-Figure 4 As shown, a low-resistance special-shaped conductor wheel pressing die according to an embodiment of the utility model comprises a mounting bracket 1, a low-resistance positioning assembly 2 and a rolling wheel 3, wherein the low-resistance positioning assembly 2 comprises a seat body 21, a rotating bearing 24, an oil supply mechanism 25, an end cover 26 and a ball 28, wherein the seat body 21 is bolted to the inner surface of the mounting bracket 1; a first mounting groove 22 is provided on an end surface of the seat body 21 away from the inner surface of the mounting bracket 1, and a second mounting groove 23 is provided on the outer side of the first mounting groove 22, the rotating bearing 24 is rotatably connected to the inner wall of the first mounting groove 22, and the oil supply mechanism 25 is arranged on the inner surface of the first mounting groove 22.

[0031] It should be noted that a straight key 31 and a keyway 241 are respectively provided at positions corresponding to the inner wall of the rotating bearing 24 on the surface of one end of the central axis of the rolling wheel 3 .

[0032] It should also be noted that a circular hole 261 is formed on the end cover 26 .

[0033] Specifically, when in use, the seat body 21 is fixedly connected to the inner surface of the mounting bracket 1, and then one end of the center axis of the rolling wheel 3 is inserted into the rotating bearing 24. The one end of the center axis of the rolling wheel 3 inserted into the rotating bearing 24 abuts against the inner wall of the rotating bearing 24 to fix the position of the rolling wheel 3 so that it will not move axially, and the use effect is good. After the position of the rolling wheel 3 is fixed, its surface contacts the surface of the ball 28 and is slidably connected.

[0034] When the rolling wheel 3 rotates, it contacts the ball 28 and drives the ball 28 to slide synchronously. The ball 28 is designed to not only limit the position, but also further reduce the friction, so the use effect is good.

[0035] The device is also provided with an oil supply mechanism 25, which supplies oil to the surface of the ball 28 to lubricate the surface, further reduce friction, and achieve the effects of cooling and noise reduction.

[0036] In one embodiment of the present invention, Figure 2 As shown, the seat body 21 includes a left half seat 211, a right half seat 212, a connecting inner rod 2121 and a rotating reciprocating mechanism 213, wherein the right half seat 212 is bolted to the inner surface of the mounting bracket 1; the connecting inner rod 2121 is fixedly connected to the center of the inner wall of the right half seat 212, one end of the connecting inner rod 2121 passes through the outside of the right half seat 212 and is fixedly connected to the left half seat 211, the first mounting groove 22 and the second mounting groove 23 are respectively opened on the end surface of the left half seat 211 away from the connecting inner rod 2121; the rotating reciprocating mechanism 213 is arranged between the right half seat 212 and the left half seat 211, and is sleeved on the outside of the connecting inner rod 2121, one end of the rotating reciprocating mechanism 213 is rotatably connected to the surface of one end of the right half seat 212, and the other end of the rotating reciprocating mechanism 213 is rotatably connected to the surface of one end of the left half seat 211.

[0037] Specifically, the structure and connection relationship of the seat body 21 are further explained. An oil supply mechanism 25 and a ball 28 are set on the left half seat 211. Oil is supplied to the ball 28 through the oil supply mechanism 25 to keep the surface of the ball 28 lubricated and reduce friction. A rotating reciprocating mechanism 213 is set on the right half seat 212. The rotating reciprocating mechanism 213 is used to intermittently drive the oil supply mechanism 25 to contact the surface of the ball 28, so that a proper amount of lubricating oil adheres to the surface of the ball 28. While playing a lubricating role, it also reduces the consumption of liquid lubricating oil and has a good use effect.

[0038] In one embodiment of the present invention, Figure 4As shown, the rotating reciprocating mechanism 213 includes a rotating disk 2131, a linkage rod 2132, a reciprocating screw rod 2133, an annular slide 2134, a connecting rod 2135 and a pushing frame 2136, wherein the rotating disk 2131 is arranged between the right half seat 212 and the left half seat 211, and is sleeved on the outside of the connecting inner rod 2121, and the two ends of the rotating disk 2131 are respectively rotatably connected to the surface of one end of the left half seat 211 and the surface of one end of the right half seat 212; the linkage rod 2132 is symmetrically arranged on the side surface of the rotating disk 2131 close to the left half seat 211, and is located on the outside of the left half seat 211, and one end of the linkage rod 2132 penetrates into the inside of the limiting hole 32 opened on the surface of the rolling wheel 3, and is slidably connected to the inner wall of the limiting hole 32; the reciprocating screw rod 2133 is fixedly connected It is connected to the side surface of the turntable 2131 close to the right half seat 212 and is located inside the right half seat 212. The reciprocating screw rod 2133 is sleeved on the outside of the connecting inner rod 2121. The annular slide 2134 is located inside the right half seat 212 and sleeved on the outside of the connecting inner rod 2121. The annular slide 2134 is threadedly connected to the outer surface of the reciprocating screw rod 2133 and is slidably connected to the inner wall of the right half seat 212; the connecting rod 2135 is fixedly connected to the center of the inner wall of the annular slide 2134 and sleeved on the outside of the connecting inner rod 2121. One end of the connecting rod 2135 penetrates into the interior of the left half seat 211 and is fixedly connected with a push rack 2136. One end of the push rack 2136 penetrates into the second mounting groove 23 and is connected to one end of the oil supply mechanism 25.

[0039] Specifically, when the rolling wheel 3 rotates, the limit hole 32 and the linkage rod 2132 cooperate with each other to synchronously drive the turntable 2131 and the reciprocating screw 2133 to rotate. The rotation of the reciprocating screw 2133 synchronously drives the annular slide 2134 to move along the outer surface of the reciprocating screw 2133 and the inner wall of the right half seat 212. The movement of the annular slide 2134 synchronously drives the connecting rod 2135 to move. The movement of the connecting rod 2135 synchronously drives the push rack 2136 to move. The movement of the push rack 2136 synchronously drives the oil storage ring 252 to move. The movement of the oil storage ring 252 synchronously drives the upper oil ring 251 and the annular sponge 254 to move. After the annular sponge 254 contacts the ball 28, part of the liquid lubricating oil adheres to the surface of the ball 28, thereby lubricating the surface of the ball 28, reducing friction, and achieving good use effect.

[0040] In one embodiment of the present invention, Figure 4As shown, a limit slot 2137 and a limit block are respectively provided at the positions corresponding to the inner wall of the right half seat 212 on the surface of the annular slide 2134, and the limit block is slidably connected to the inner wall of the limit slot 2137; a groove (not shown in the figure) is provided on the surface of one end of the left half seat 211 close to the turntable 2131, and is communicated with the interior of the second mounting groove 23, and a push rack 2136 is arranged in the groove, one end of the push rack 2136 is connected to one end of the connecting rod 2135, and the other end of the push rack 2136 passes through the interior of the second mounting groove 23 and is connected to one end of the oil supply mechanism 25.

[0041] Specifically, the limiting card slot 2137 and the limiting card block are designed to ensure the horizontal movement of the annular slide 2134, and the groove design is convenient for placing the push rack 2136, so the use effect is good.

[0042] In one embodiment of the present invention, Figure 3 As shown, the oil supply mechanism 25 includes an upper oil ring 251, an oil storage ring 252, an upper oil pipeline 253, an annular sponge 254, a valve 255 and an oil supply nozzle 256, wherein the upper oil ring 251 and the oil storage ring 252 are respectively slidably connected to the inner wall of the second mounting groove 23 and are connected through the upper oil pipeline 253; one end of the push frame 2136 penetrates into the interior of the second mounting groove 23 and is connected to the surface of one end of the oil storage ring 252; an annular sponge 254 is provided on the surface of one end of the upper oil ring 251 close to the ball 28, one end of the annular sponge 254 is connected to the interior of the upper oil ring 251, and the other end of the annular sponge 254 is in contact with the surface of the ball 28; the surface of the upper oil pipeline 253 and the surface of the oil storage ring 252 are respectively provided with a valve 255 and an oil supply nozzle 256, and one end of the valve 255 and the oil supply nozzle 256 respectively penetrate out of the outside of the left half seat 211.

[0043] It should be noted that the oil supply nozzle 256 described in this embodiment has a built-in one-way valve.

[0044] Specifically, liquid lubricating oil is injected into the oil storage ring 252 through the oil supply nozzle 256. After the valve 255 is opened, the liquid lubricating oil enters the upper oil ring 251 through the oil supply pipe 253. After the liquid lubricating oil inside the upper oil ring 251 contacts with the annular sponge 254, part of the liquid lubricating oil is absorbed by the annular sponge 254. After the annular sponge 254 that absorbs the liquid lubricating oil contacts with the ball 28, part of the liquid lubricating oil adheres to the surface of the ball 28, thereby lubricating the ball 28, reducing friction, and achieving good use effect.

[0045] Among them, the uninterrupted contact between the ball 28 and the annular sponge 254 will cause the liquid lubricant on the surface of the ball 28 to increase. When the liquid lubricant increases to a certain amount, part of the liquid lubricant will drip under the action of gravity, causing waste of resources and inconvenient cleaning. In order to prevent the above situation from occurring, the device is provided with a rotating reciprocating mechanism 213. The rotating reciprocating mechanism 213 intermittently drives the annular sponge 254 to contact the ball 28, so that an appropriate amount of liquid lubricant adheres to the surface of the ball 28, which not only plays a lubricating role, but also reduces the consumption of liquid lubricant, and has a good use effect.

[0046] In one embodiment of the present invention, Figure 3 As shown, a waist-shaped through groove 210 is provided on the surface of the left half seat 211 to facilitate one end of the valve 255 and one end of the oil supply nozzle 256 to pass through, and the waist-shaped through groove 210 is connected to the inside of the second installation groove 23.

[0047] It should be noted that the valve 255 and the oil supply nozzle 256 described in this embodiment are respectively slidably connected to the inner wall of the waist-shaped through groove 210.

[0048] Specifically, the waist-shaped through groove 210 is designed to facilitate one end of the valve 255 and one end of the oil supply nozzle 256 to pass through the outside of the left half seat 211, thereby facilitating the operation of oil filling and opening and closing the valve 255.

[0049] In summary, in the embodiment of the utility model, a low-resistance special-shaped conductor wheel pressing mold, the ball 28 provided in the device not only realizes the limiting function of the rolling wheel 3, but also significantly reduces the friction between the surface of the rolling wheel 3, and effectively reduces the degree of wear and improves the transmission efficiency by reducing the friction. In addition, the oil supply mechanism 25 provided in the device can supply oil to the ball 28, so that the surface of the ball 28 is fully lubricated, further reducing the friction, and achieving the effect of cooling and noise reduction.
