Referring to fig. 3 to 5, in some embodiments, the fixed compression shear unit 220 includes a driving element 221, a second mounting plate 222, and a first cutter 223.

The driving element 221 is preferably a motor, and includes a body 2211 and an output shaft 2212, the body 2211 is fixedly mounted on a side of the second mounting plate 222 far from the guide rail 212, and an end of the output shaft 2212 far from the body 2211 passes through a through hole of the second mounting plate 222 and the mounting position 215 of the support 210 and protrudes out of the mounting position 215 to be located at the other end of the fixed compression shear unit 220. The first cutter 223 is preferably a circular cutter, the outer periphery of the first cutter 223 is a sharp edge continuously encircling the circumference of the first cutter 223, the first cutter 223 is fixedly sleeved at one end of the output shaft 2212 of the driving element 221 extending out of the mounting position 215, and when the driving element 221 starts to operate, the output shaft 2212 rotates around the self axis direction, so that the first cutter 223 can be driven to rotate around the self axis direction.
In some embodiments, the movable compression shear unit 230 includes a slider 231, a connection shaft 232, and a second cutter 233. The sliding block 231 is located at one end of the movable compression shear unit 230, is received in the mounting position 215 of the support 210, and is movably limited between the two rails 212 of the support 210, and opposite ends of the sliding block 231 along the second direction are respectively limited in the limiting groove 2311 of one rail 212 and can move up and down along the third direction relative to the rail 212 to approach or separate from the fixed compression shear unit 220. In a preferred embodiment, the slider 231 is provided with through holes communicating two opposite sides of the slider 231 along the first direction, one end of the connecting shaft 232 is inserted through the through holes of the slider 231 and exposed out of the slider 231 to be located at the other end of the movable compression shear unit 230, and one end of the connecting shaft 232 exposed out of the slider 231 and one end of the output shaft 2212 of the driving element 221 extending out of the mounting position 215 in the fixed compression shear unit 220 are located at the same side of the support 210.

In a preferred embodiment, the slider 231 is provided with a threaded hole 2312 along the third direction near to one end of the handle 214, one end of the handle 214 is correspondingly provided with threads, and one end of the handle 214 provided with threads is inserted into the threaded hole 2312 of the slider 231, so that the handle 214 is mounted in the movable compression shear unit 230 and can rotate relative to the slider 231 about an axis along the third direction under the action of external force.
In this way, the sliding block 231 and the handle 214 are connected through the screw, so that a reverse self-locking characteristic is formed between the sliding block 231 and the handle 214, when the handle 214 is rotated, the sliding block 231 can slide down and down in the limit groove 2311 of the guide rail 212, so as to adjust the size of the shearing gap formed by the first cutter 223 and the second cutter 233, meanwhile, the sliding block 231 can rotate through the handle 214 to generate linear motion, and the handle 214 cannot generate rotary motion through the linear motion of the sliding block 231, therefore, once the rotation position of the handle 214 is determined during the operation of the device, the position of the sliding block 231 is also determined, the center distance between the first cutter 223 and the second cutter 233 is not 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 D and the effective height of the hanger piece 410 is T, the condition formula for effectively cutting the copper wire 20 is:
H≤D+T
in the above formula, H is the center distance between the first blade 223 and the second blade 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 needs to be smaller than the sum of the diameter of the cutters and the height of the hanger piece 410, that is, the size of the press-cutting gap needs to be smaller than the diameter of the copper wire 20 so that the copper wire 20 can be effectively cut.
Meanwhile, when the copper wire 20 is wound around the hanger piece 410 in tight fit with the hanger piece 410, in order to protect the hanger piece 410 and reduce the abrasion of the first cutter 223 or the second cutter 233, the size of the press-shear gap is required to be slightly larger than the height of the hanger piece 410, and thus, the above formula may be changed as follows:
D+T+0.05＝H(mm)
meaning that the size of the press-shearing gap is 0.05mm larger than that of the hanger piece 410, the first cutter 223 and the second cutter 233 cannot touch the hanger piece 410 during the 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 press-shear mechanism 200 further includes a wiper 240, the wiper 240 being mounted on a side of one of the rails 212 remote from the other rail 212, the wiper 240 being located at an end of the hanger plate 410 that is higher than the hanger plate 410 but lower than the outer circumference of the copper wire 20 in the third direction. Thus, when the copper wire 20 is cut by the punching and shearing mechanism 200, the cut residual copper wire 20 may still hang on the hanger piece 410, and as the hanger 400 continues to move forward along the second direction, the doctor blade 240 can scrape the cut copper wire 20 remaining on the hanger piece 410 off from the hanger piece 410, so that the cutting and dismounting device 10 provided by the application can cut and completely dismount the copper wire 20 wound on the hanger 400, and the procedure 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 multiple bearing sets. The support 310 includes a support frame 311, a support plate 312 and a bearing seat 313, wherein the support frame 311 is in an L-shaped structure and is formed by integrally processing a first cross plate 3111 and a first vertical plate 3112, the first cross plate 3111 and the second cross plate 3121 are perpendicular to each other, and the first cross plate 3111 is fixedly mounted on one end of the base 100 along a first direction far away from the compression shear mechanism 200.
In a preferred embodiment, the support plate 312 is also in an "L" shape, specifically, the support plate 312 is integrally formed by a second transverse 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 transverse plate 3121 of the support plate 312 extends horizontally in the first direction in a direction away from the support frame 311, the bearing housing 313 is preferably in a rectangular cuboid structure for mounting the bearing 320, and one end is fixedly mounted on the second transverse plate 3121 of the support plate 312. In a preferred embodiment, the bearing housing sets have two sets, each set having two bearings 320, one bearing 320 being rotatably mounted on the top surface of the bearing housing 313 and the other bearing 320 being rotatably mounted on the side of the bearing housing 313 remote from the support plate 312, each bearing 320 being rotatable about its own axis such that the central axes of the two bearings 320 in a set of bearing housing 313 are perpendicular to each other, and the radial direction of all bearings 320 is perpendicular to the radial direction of bearings 320.
Thus, 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 and removed 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 piece 410 at the end of the hanger 400 is overlapped with the outer circumferential surface of the bearing 320, when the hanger 400 is pushed under the action of external force, all the bearings 320 rotate around the axis direction of the hanger 400, so that the hanger 400 is assisted to move, the purpose of assisting the hanger 400 to move along the second direction is achieved, and therefore, a worker can push the hanger 400 to move without great effort, and the labor intensity of the worker is greatly reduced.
In a preferred embodiment, as shown in fig. 1, the first cross plate 3111 of the support frame 311 is provided with two waist holes 3113 arranged at intervals along the second direction, each waist hole 3113 communicates 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 of the support frame 311 mounted on the base 100 is adjustable along the first direction, and the distance between the auxiliary support mechanism 300 and the pressing and shearing mechanism 200 can be increased or decreased, so that the shearing and unloading device 10 provided by the invention can be adapted to hangers 400 with different width sizes.
As shown in fig. 8, the distance B from the fastening screw 101 of the base 100 to the end surface of the pressing and shearing mechanism 200 facing one end of the auxiliary supporting mechanism 300 is a constant value, and the distance N from the fastening screw 101 to the bus bar of the outer ring of the bearing 320 of the auxiliary supporting mechanism 300 is variable because the distance between the auxiliary supporting mechanism 300 and the pressing and shearing mechanism 200 is adjustable. Then, 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 hanger 400 are different, N may be adjusted before the shearing work of the copper wire 20 is performed, so that the hanger 400 can be effectively supported.
The shearing and unloading device 10 is shown in fig. 1 to 3, and the using method is as follows:
first, before using the shearing and unloading device 10, the auxiliary supporting mechanism 300 is slid back and forth on the base 100 along the first direction to adjust the distance between the auxiliary supporting mechanism 300 and the shearing mechanism 200 until the distance between the shearing mechanism 200 and the auxiliary supporting mechanism 300 can firmly support the hanger 400, and then the position of the auxiliary supporting mechanism 300 is fixed.
Subsequently, when the copper wire 20 is cut and removed, the handle 214 is rotated to lower the slider 231 and the second blade 233 in the third direction, and the distance between the first blade 223 and the second blade 233 is shortened until the edge of the outer periphery of the second blade 233 contacts the copper wire 20.
Then, the motor is restarted, at this time, the first cutter 223 rotates around the own axis direction, the worker holds one end of the hanger 400 in the second direction and pushes the hanger 400 forward, and simultaneously drives the first cutter 223 and the second cutter 233 to rotate synchronously in opposite directions, and the plurality of copper wires 20 wound on the hanger 400 at intervals can be engaged under the opposite rotation of the first cutter 223 and the second cutter 233 to sequentially pass through the shearing gap and be sheared and unloaded in batches, thereby gradually completing the shearing and unloading of the plurality of copper wires 20 wound on the hanger 400 in sequence.
When the copper wire 20 wound on one end of the hanger 400 in the first direction is cut and removed, the copper wire 20 wound on the other end of the hanger 400 in the first direction is cut and removed, and the hanger 400 can be turned over and then pushed in the direction opposite to the previous cutting and removing process, so that the hanger 400 moves in the second direction in the opposite direction, and the copper wire 20 wound on the other end of the hanger 400 in the first direction is cut and removed.
It should be noted that, the shearing and detaching device 10 of the above embodiment can only shear and detach the copper wire 20 wound around one end of the hanger 400 at a time. Although a larger number of copper wires 20 can be sheared and unloaded at a time, the labor intensity of workers can be greatly reduced compared with a manual shearing and unloading mode, as a better implementation mode, the shearing and unloading device 10 can be further expanded, so that a larger number of copper wires 20 can be sheared and unloaded.
Specifically, in some embodiments, a greater number of the pressing and shearing mechanisms 200 may be installed in the direction of the shearing and detaching device 10 in the third direction, so that the copper wires 20 wound on the plurality of the hangers 400 stacked in the third direction may be sheared and detached at once.
In a preferred embodiment, since the pressing and shearing mechanism 200 also has an auxiliary supporting function, the auxiliary supporting mechanism 300 of the shearing and unloading device 10 can be replaced by the pressing and shearing mechanism 200, and the first cutter 223 and the second cutter 233 can be additionally installed on the auxiliary supporting mechanism 300, so that the pressing and shearing mechanism 200 is installed at two ends of the base 100 along the first direction, and copper wires 20 at two ends of the hanging tool 400 along the first direction can be simultaneously sheared and unloaded when the hanging tool 400 is pushed along the second direction. Further, on the basis of the embodiment, a greater number of the pressing and shearing mechanisms 200 can be installed in the direction of the third direction, so that a greater number of copper wires 20 can be sheared and unloaded at a time, and a plurality of the copper wires 20 at both ends of the hanger 400 stacked along the third direction can be sheared and unloaded at a time.
The expansion mode can be selected according to the needs, and is not limited herein. It should be further noted that, in the embodiment of the shearing and unloading device 10 with multiple pressing and shearing mechanisms 200, as the conditions allow, only any one of the pressing and shearing mechanisms 200 is provided with the driving element 221, and each pressing and shearing mechanism 200 is not required to be provided with the driving element 221, so that the labor intensity of workers can be reduced, the working efficiency can be improved, and the purpose of saving energy can be achieved.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
