In this manner, the handle 214 cannot move up and down in the third direction, but can rotate relative to the base plate 211, the guide rail 212, and the first mounting plate 213 about an axis in the third direction by an external force.

Referring to fig. 3 to 5, in some embodiments, the fixed press-shearing unit 220 includes a driving element 221, a second mounting plate 222, and a first cutter 223. The second mounting plate 222 is located at one end of the fixed pressing and shearing unit 220, and is fixedly mounted on one side of the two guide rails 212 of the support 210 away from the auxiliary supporting mechanism 300 along the first direction, and the second mounting plate 222 is provided with through holes communicating two opposite sides of the second mounting plate 222 along the first direction. The driving member 221 is preferably a motor, and includes a body 2211 and an output shaft 2212, the body 2211 is fixedly installed on one side of the second mounting plate 222 far from the guide rail 212, and one end of the output shaft 2212 far from the body 2211 passes through the through hole of the second mounting plate 222 and the mounting position 215 of the support 210 and extends out of the mounting position 215 to be located at the other end of the fixed compression-shearing unit 220. The first cutter 223 is preferably a circular cutter, the outer periphery of the first cutter 223 is a sharp edge which continuously surrounds the circumference of the first cutter 223, the first cutter 223 is fixedly sleeved on one end, extending out of the mounting position 215, of the output shaft 2212 of the driving element 221, and when the driving element 221 starts to operate, the output shaft 2212 rotates around the axis direction of the output shaft, so that the first cutter 223 can be driven to rotate around the axis direction of the output shaft.

In some embodiments, the movable press shear unit 230 includes a slider 231, a connecting shaft 232, and a second cutter 233. The sliding block 231 is located at one end of the movable press shearing unit 230, is accommodated in the mounting position 215 of the support 210, and is movably limited between the two guide rails 212 of the support 210, and two opposite ends of the sliding block 231 along the second direction are respectively limited in the limiting groove 2311 of one guide rail 212, and can move up and down along the third direction relative to the guide rail 212 to approach or leave the fixed press shearing unit 220. In a preferred embodiment, the sliding block 231 is provided with a through hole communicating with two opposite sides of the sliding block 231 along the first direction, one end of the connecting shaft 232 is inserted into the through hole of the sliding block 231 and exposed out of the sliding block 231 to be located at the other end of the movable press shearing unit 230, and one end of the connecting shaft 232 exposed out of the sliding block 231 and one end of the output shaft 2212 of the driving element 221 in the fixed press shearing unit 220 extending out of the mounting position 215 are located at the same side of the support 210. The shape of the second cutter 233 is identical to that of the first cutter 223, and the second cutter 233 is rotatably sleeved on one end of the connecting shaft 232 extending out of the slider 231, so that the second cutter 233 can rotate around its own axis direction. In a better embodiment, one end of the slider 231 near the handle 214 along the third direction is provided with a threaded hole 2312, one end of the handle 214 is correspondingly provided with a thread, and the end of the handle 214 provided with the thread is inserted into the threaded hole 2312 of the slider 231, so that the handle 214 is installed in the movable press-shearing unit 230 and can rotate around an axis along the third direction relative to the slider 231 under the action of an external force.

In this way, the slider 231 and the handle 214 are connected through the screw thread, so that a reverse self-locking characteristic is formed between the slider 231 and the handle 214, when the handle 214 is rotated, the slider 231 can slide up and down in the limiting groove 2311 of the guide rail 212 along the third direction, so as to adjust the size of the pressure shearing gap formed by the first cutter 223 and the second cutter 233, meanwhile, the slider 231 can generate a linear motion through the rotation of the handle 214, and the handle 214 cannot generate a rotary motion through the linear motion of the slider 231, so that when the device works, once the rotation position of the handle 214 is determined, the position of the slider 231 is also determined, the center distance between the first cutter 223 and the second cutter 233 will not be changed, and the effect of shearing the copper wire 20 is better. As shown in fig. 6, if the outer diameters of the first cutter 223 and the second cutter 233 are both D, and the effective height of the hanger piece 410 is T, the condition formula for effectively cutting the copper wire 20 is as follows:

H≤D+T

in the above formula, H is the center-to-center distance between the first cutter 223 and the second cutter 233.

Therefore, in order to cut the copper wire 20 wound around the hanger piece 410, the center distance between the first cutter 223 and the second cutter 233 is smaller than the sum of the diameter of the cutter and the height of the hanger piece 410, that is, the size of the press-cutting gap is smaller than the diameter of the copper wire 20, so that the copper wire 20 can be cut effectively.

Meanwhile, when the copper wire 20 is wound on the hanger piece 410 and is tightly fitted with the hanger piece 410, in order to protect the hanger piece 410 and reduce the wear of the first cutter 223 or the second cutter 233, the size of the press-shearing gap needs to be slightly larger than the height of the hanger piece 410, and then, the above formula may be changed as follows:

D+T+0.05＝H(mm)

the size of the press shearing gap needs to be 0.05mm larger than that of the hanger piece 410, and the first cutter 223 and the second cutter 233 can not touch the hanger piece 410 during press shearing operation, so that the hanger piece 410 can be effectively protected, and the abrasion of the first cutter 223 or the second cutter 233 can be reduced.

In some embodiments, as shown in fig. 1, the pressing and shearing mechanism 200 further includes a wiper 240, the wiper 240 is mounted on a side of one of the guide rails 212 far from the other guide rail 212, and an end of the wiper 240 close to the hanger piece 410 in the third direction is higher than the hanger piece 410 but lower than the outer periphery of the copper wire 20. In this way, when the copper wire 20 is cut by the press-cutting mechanism 200, the cut residual copper wire 20 may still be hung on the hanger piece 410, and as the hanger 400 continues to move in the second direction, the scraper 240 can scrape the cut copper wire 20 remaining on the hanger piece 410 off the hanger piece 410, so that the cutting device 10 provided by the present application can cut and completely remove the copper wire 20 wound on the hanger 400, and a process of manually removing the residual copper wire 20 is omitted.

In some embodiments, as shown in fig. 3 and 7, the auxiliary support mechanism 300 includes a bracket 310 and a plurality of sets of bearing sets. Wherein the support 310 includes support frame 311, backup pad 312 and bearing frame 313, and the support frame 311 is "L" shape structure, is formed by a first diaphragm 3111 and a first riser 3112 integrated into one piece, and first diaphragm 3111 and second diaphragm 3121 mutually perpendicular, wherein first diaphragm 3111 fixed mounting is in the one end that the press-shear mechanism 200 was kept away from along the first direction in base 100.

In a preferred embodiment, the support plate 312 is also in an "L" shape, and specifically, the support plate 312 is formed by integrally forming a second horizontal plate 3121 and a second vertical plate 3122, wherein the second vertical plate 3122 of the support plate 312 is fixedly mounted on the first vertical plate 3112 of the support frame 311 by screws, the second horizontal plate 3121 of the support plate 312 horizontally extends along the first direction in a direction away from the support frame 311, the bearing seat 313 is preferably in a rectangular cuboid structure for mounting the bearing 320, and one end of the bearing seat is fixedly mounted on the second horizontal plate 3121 of the support plate 312. In a preferred embodiment, the bearing seat set has two sets, each set has two bearings 320, one bearing 320 is rotatably mounted on the top surface of the bearing seat 313, the other bearing 320 is rotatably mounted on the side surface of the bearing seat 313 away from the support plate 312, each bearing 320 can rotate around its own axis direction, so that the central axes of the two bearings 320 in the set of bearing seats 313 are perpendicular to each other, and the radial directions of all the bearings 320 are perpendicular to the radial directions of the bearings 320.

In this way, when the hanger 400 moves in the second direction, one end of the hanger 400 in the first direction is supported by the press shearing mechanism 200, and the copper wire 20 wound on the end hanger piece 410 can be cut off by the press shearing mechanism 200, and the other end of the hanger 400 in the first direction is supported by the auxiliary supporting mechanism 300. Specifically, the hanger plate 410 at the end of the hanger 400 is lapped on the outer circumferential surface of the bearing 320, and when the hanger 400 is pushed under the action of external force, all the bearings 320 rotate around the axis direction thereof, so as to provide assistance for the movement of the hanger 400, and achieve the purpose of assisting the hanger 400 to move along the second direction, so that a worker can push the hanger 400 to move without needing much effort, thereby greatly reducing the labor intensity of the worker.

In a better embodiment, as shown in fig. 1, the first cross plate 3111 of the supporting frame 311 is provided with two waist holes 3113 arranged at intervals along the second direction, each waist hole 3113 is communicated with two sides of the horizontal plate along the third direction, correspondingly, two fastening screws 101 of each set of fastening screws 101 in the base 100 are inserted into one waist hole 3113, so that the position where the supporting frame 311 is installed on the base 100 is adjustable along the first direction, thereby increasing or decreasing the distance between the auxiliary supporting mechanism 300 and the press shear mechanism 200, and thus the shearing device 10 provided by the present invention can be adapted to hangers 400 with different width dimensions.

As shown in fig. 8, a distance B from the fastening screw 101 of the base 100 to an end surface of the press shear mechanism 200 facing one end of the auxiliary support mechanism 300 is a constant value, and a distance N from the fastening screw 101 to a generatrix of an outer ring of the bearing 320 of the auxiliary support mechanism 300 is variable due to an adjustable distance between the auxiliary support mechanism 300 and the press shear mechanism 200. Thus, there are:

B＝b+N+2C

in the above formula, C is the diameter of the sheared copper wire 20.

When the widths b of the hangers 400 are different, N can be adjusted before the cutting work of the copper wire 20 is performed, so that the hangers 400 can be effectively supported.

As shown in fig. 1 to 3, the shearing device 10 is used as follows:

first, before the cutting device 10 is used, the auxiliary supporting mechanism 300 is slid back on the base 100 in a first direction to adjust the distance between the auxiliary supporting mechanism 300 and the press-shearing mechanism 200 until the distance is adjusted to enable the press-shearing mechanism 200 and the auxiliary supporting mechanism 300 to stably support the hanger 400, and then the position of the auxiliary supporting mechanism 300 is fixed.

Subsequently, when the copper wire 20 is cut off, the handle 214 is rotated to lower the slider 231 and the second cutter 233 in the third direction, and the distance between the first cutter 223 and the second cutter 233 is shortened until the cutting edge of the outer periphery of the second cutter 233 contacts the copper wire 20.

And then, the motor is started, at the moment, the first cutter 223 rotates around the axis direction of the motor, a worker holds one end of the hanger 400 in the second direction and pushes the hanger 400 to move forwards, and simultaneously drives the first cutter 223 and the second cutter 233 to synchronously rotate in opposite directions, a plurality of copper wires 20 wound on the hanger 400 at intervals can be occluded under the opposite rotation of the first cutter 223 and the second cutter 233 to sequentially pass through a compression shearing gap and be sheared in batches, and therefore shearing of the plurality of copper wires 20 wound on the hanger 400 is gradually and sequentially completed.

When the copper wire 20 wound on one end of the hanger 400 along the first direction is cut, the copper wire 20 wound on the other end of the hanger 400 along the first direction needs to be cut, at this time, the hanger 400 can be turned over, and then the hanger 400 is pushed in the direction opposite to the previous cutting process, so that the hanger 400 moves in the direction opposite to the second direction, and the copper wire 20 wound on the other end of the hanger 400 along the first direction is cut.

It should be noted that the shearing apparatus 10 of the above embodiment can only shear the copper wire 20 wound around one end of the hanger 400 at a time. Although a greater number of copper wires 20 can be cut at a time, which can greatly reduce the labor intensity of workers compared with manual cutting, as a better embodiment, the cutting device 10 can be further expanded to cut a greater number of copper wires 20.

Specifically, in some embodiments, a greater number of the compression-shearing mechanisms 200 may be installed in the direction of the third direction of the shearing device 10, so that the copper wires 20 wound on the plurality of hangers 400 stacked in the third direction may be simultaneously sheared at one time.

In a better embodiment, since the press shearing mechanism 200 also has the function of auxiliary support, the auxiliary support mechanism 300 of the shearing device 10 can be replaced by the press shearing mechanism 200, and the first cutter 223 and the second cutter 233 can also be additionally installed on the auxiliary support mechanism 300, so that the press shearing mechanism 200 is installed at both ends of the base 100 along the first direction, and when the hanger 400 is pushed along the second direction, the copper wires 20 at both ends of the hanger 400 along the first direction can be simultaneously sheared. On the basis of this embodiment, a greater number of press-shearing mechanisms 200 may be installed in the third direction, so as to realize one-time shearing of a greater number of copper wires 20, so that the plurality of copper wires 20 at both ends of the rack 400 stacked in the third direction in the first direction may be sheared at one time.

The expansion mode can be selected according to needs, and is not limited herein. It should be further noted that, if conditions allow, in the above-described expanded embodiment of the shearing device 10 having a plurality of press-shearing mechanisms 200, as long as any one of the press-shearing mechanisms 200 is provided with the driving element 221, it is not necessary to install the driving element 221 on each press-shearing mechanism 200, so that the labor intensity of workers can be reduced, the working efficiency can be improved, and meanwhile, the energy-saving purpose can be achieved.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express one of the embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
