Technical Field

[0001] The present invention relates to a wire assembly and winding structure and a cutting method thereof, and in particular to a wire assembly and winding structure and a cutting method thereof applied in the technical field of cutting related fields. Background Art

[0002] Chinese patent CN117621268B discloses an ultra-fine wire single-station stone cutting machine, in which the wire winding cutting structure is provided with two winding rollers, one for releasing the wire and the other for taking it up, which cooperate with multiple turns of winding on the roller to form a cutting wire net using a diamond wire, thereby achieving the effect of multi-wire cutting.

[0003] However, since the cutting wire net is one piece, a partial break will affect the overall cutting, requiring shutdown for maintenance, affecting the overall cutting efficiency. In addition, two winding rollers are required to accommodate the related mechanisms of the winding rollers, which invisibly increases the cost. Summary of the invention

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the wire winding cutting structure in the existing multi-wire cutting machine is easy to affect the cutting efficiency and has a relatively high cost.

[0005] In order to solve the above problems, the present invention provides a wire assembly winding structure, including a winding unit, a conductor unit and a tension adjustment unit. The winding unit includes a mobile base, a forward and reverse motor is fixedly installed on the upper end of the mobile base, and the output shaft of the forward and reverse motor is fixedly connected to a wire roller assembly.

[0006] In the above-mentioned wire winding structure, only one winding roller is used to simultaneously realize wire taking-up and winding. Compared with the setting of two winding rollers in the prior art, the cost is effectively reduced. When multi-wire cutting is required, multiple sets of the winding structure can be set. When the diamond wire breaks during cutting, it only affects the local area, without the need for overall shutdown for maintenance, effectively reducing the impact on cutting efficiency.

[0007] As a further improvement of the present application, two cutting lines are formed between the left guide wheel and the right guide wheel, and the routing directions of the two cutting lines are opposite, and the winding directions of the two ends of the diamond wire on the winding roller are also opposite.

[0008] As a further improvement of the present application, each time the winding roller rotates one circle, the wire adjusting assembly and the adjusting screw drive the slide rail to translate the distance between the two winding grooves.

[0009] As a further improvement of the present application, the adjustment assembly includes a back plate installed on the cutting machine, two linear guide rails fixedly connected to the back plate, a limit seat fixedly connected to the end of the tension wheel away from the forward and reverse motor, and a tension measurement and control unit installed between the back plate and the limit seat, and the two linear guide rails are both movable through the limit seat.

[0010] As a further improvement of the present application, the tension measurement and control unit includes a movable pulley fixedly connected to the limit seat, a fixed pulley fixedly connected to the back plate, and a pulley line wound around the movable pulley and the fixed pulley, one end of the pulley line is close to the fixed pulley and fixedly connected to the back plate, and a counterweight is provided at the other end of the pulley line.

[0011] As a further improvement of the present application, the counterweight is fixedly connected to the pulley line, and the counterweight falls naturally.

[0012] As another improvement of the present application, a wire bow detection unit is also provided on the counterweight, and the wire bow detection unit includes a conical rod fixedly connected to the upper end of the limit seat, a bearing ring fixedly connected to the outer end of the conical rod, a detection ring fixedly connected to the back plate, and an alarm installed at the bottom of the counterweight.

An external pressure sensor is fixedly connected to the upper end of the bearing ring, and the axis of the external pressure sensor intersects with the detection ring.

Two grooves are drilled on the inner wall of the outer ring body, and internal pressure sensors are installed on the inner walls of the two grooves, and the two grooves and the two diaphragms are cross-distributed with each other.

[0015] A cutting method using a wire group winding structure includes the following steps: S1. When in use, install the wire assembly and winding structure on the cutting machine, and then transport the workpiece to be cut to the cutting line through the mobile assembly; S2, turn on the forward and reverse motors and drive the winding roller to rotate, so that one cutting wire is in a pay-out state on the winding roller as it rotates, and the other cutting wire is in a take-up state on the winding roller as it rotates. When the forward and reverse motors continue to rotate, the two cutting wires are dynamic. At this time, the moving component continues to move the workpiece to be cut so that it contacts the cutting wire; S3. After rotating a certain number of times, the forward and reverse motors are controlled to rotate in the reverse direction, so that the moving directions of the two cutting lines are changed, and the directions of the forward and reverse motors are continuously and alternately changed, so that the two cutting lines can move back and forth, and reciprocating cutting of the workpiece to be cut is realized.

[0016] In summary, only one winding roller is used to achieve wire taking-up and winding at the same time, which effectively reduces the cost compared with the setting of two winding rollers in the prior art, and when multi-wire cutting is required, multiple groups of the winding structure can be set. When the diamond wire breaks during cutting, it only affects the local area, and there is no need to shut down the entire machine for maintenance, which effectively reduces the impact on the cutting efficiency.

DETAILED DESCRIPTION

[0019] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0020] The first implementation method: Figure 1A wire assembly and winding structure is shown, including a winding unit, a conductor unit and a tension adjustment unit. The winding unit includes a mobile base 1, a forward and reverse motor 2 is fixedly installed on the upper end of the mobile base 1, and the output shaft of the forward and reverse motor 2 is fixedly connected to a wire roller assembly 3. The conductor unit includes two upper and lower corresponding wire control wheels 51, two left guide wheels 52 and two right guide wheels 53. In a top view, the connecting lines between the wire control wheel 51, the left guide wheel 52 and the right guide wheel 53 form a right triangle. The tension adjustment unit includes a tension wheel 54 and an installation The adjustment assembly 6 is mounted on the tension wheel 54, and one end of the diamond wire 33 is fixedly connected to the end of the winding roller 32 close to the forward and reverse motor 2 and is wound around the winding roller 32 at least once. The other end of the diamond wire 33 passes through the upper control wheel 51, the left guide wheel 52, the right guide wheel 53, the tension wheel 54 and the lower right guide wheel 53, the left guide wheel 52, the control wheel 51 and returns to the winding roller 32. The diamond wire 33 that returns to the winding roller 32 is wound around the other end of the winding roller 32 again and is fixedly connected to the end of the winding roller 32.

[0021] like Figure 3 In the figure, the dark arrow indicates the routing direction, and the light arrow indicates the winding direction. Two cutting lines are formed between the left guide wheel 52 and the right guide wheel 53, and the routing directions of the two cutting lines are opposite. The winding directions of the two ends of the diamond wire 33 on the winding roller 32 are also opposite. Therefore, when the forward and reverse motor 2 drives the winding roller 32 to rotate, one end of the diamond wire 33 wound on the winding roller 32 is in a winding state, and the other end is in a pay-off state, so that only one winding roller 32 is used to achieve synchronous winding and pay-off. Compared with the two separate winding and pay-off rollers in the prior art, the cost investment is effectively reduced.

[0022] like Figure 2-3 The wire roller assembly 3 includes two roller frames 31 and a winding roller 32 mounted between the two roller frames 31. A plurality of evenly distributed winding grooves 301 are formed at the outer end of the winding roller 32. A diamond wire 33 is wound along the plurality of winding grooves 301 on the winding roller 32. The movable base 1 includes two slide rails 12, a bottom plate 11 slidably connected to the two slide rails 12, and a positioning screw 13 fixedly connected to the lower end of the bottom plate 11. The positioning screw 13 is located between the two slide rails 12.

[0023] like Figure 4The winding roller 32 is fixedly connected with a wire adjustment assembly 4 at the shaft end away from the forward and reverse motor 2. The wire adjustment assembly 4 includes a reducer 41 fixedly connected to the shaft end of the winding roller 32, a driving wheel 42 fixedly connected to the output end of the reducer 41, and a passive wheel 43 threadedly connected to the outer end of the adjusting screw 13. The outer ends of the driving wheel 42 and the passive wheel 43 are connected with belts 44. The outer cover of the passive wheel 43 is provided with a protective cover 401, and the protective cover 401 is fixedly connected to the lower end of the base plate 11. The adjusting screw 13 movably penetrates the protective cover 401. When the winding roller 32 rotates to drive the diamond wire 33 to reciprocate for cutting, the driving wheel 42 can be decelerated by the action of the reducer 41, and the belt 44 is used to transmit the inner rotation to the adjusting screw 13, so that the passive wheel 43 rotates on the adjusting screw 13, realizing lateral movement along the adjusting screw 13, thereby driving the base plate 11 sliding with the slide rail 12 and the wire roller assembly 3 above it to move laterally as a whole.

[0024] It is worth noting that by adjusting the gear ratio in the reducer 41, the wire adjusting assembly 4 and the adjusting screw 13 drive the slide rail 12 to translate the distance between the two winding grooves 301 every time the winding roller 32 rotates one circle, so that the diamond wire 33 can remain perpendicular to the winding roller 32 regardless of whether it is paying out or taking up the wire, thereby effectively ensuring that when the winding roller 32 rotates, the diamond wire 33 can be stably paid out and taken up, and is not easy to get out of the winding groove 301, thereby effectively maintaining stability during cutting.

[0025] In addition, in the specific implementation, the lateral movement of the bottom plate 11 and the wire roller assembly 3 above it can be directly controlled by a servo motor to adapt to the reeling and unreeling of the diamond wire 33. Other mechanical structures that can be laterally moved can also be used to achieve the lateral movement of the bottom plate 11 and the wire roller assembly 3 above it.

[0026] like Figure 5-6The adjustment component 6 includes a back plate 61 installed on the cutting machine, two linear guide rails 62 fixedly connected to the back plate 61, a limit seat 63 fixedly connected to the end of the tension wheel 54 away from the forward and reverse motor 2, and a tension measurement and control unit installed between the back plate 61 and the limit seat 63. The two linear guide rails 62 are movable through the limit seat 63. The tension measurement and control unit includes a movable pulley 601 fixedly connected to the limit seat 63, a fixed pulley 602 fixedly connected to the back plate 61, and a pulley line 604 wound around the movable pulley 601 and the fixed pulley 602. One end of the pulley line 604 is close to the fixed pulley 602 and fixedly connected to the back plate 61, and the other end of the pulley line 604 is provided with a counterweight hammer 603. The weight 603 is fixedly connected to the pulley line 604, and the counterweight 603 hangs naturally, wherein the counterweight 603 is used as a counterweight. During cutting, the friction between the diamond wire 33 and the material may cause the diamond wire 33 to bend and form a wire bow, which may cause the tension wheel 54 to move closer to the right guide wheel 53. The counterweight 603 is used as a counterweight, which can prevent the tension wheel 54 from moving toward the right guide wheel 53 without restriction, and can limit the wire bow formed by the diamond wire 33 to exist relatively stably, thereby effectively maintaining the tension of the diamond wire 33 and ensuring the stability of the cutting process. During specific use, the demand for the wire bow can be judged according to the material to be cut, and then the counterweight 603 of different weights can be replaced.

[0027] In addition, during actual cutting, when the tension wheel 54 moves toward the right guide wheel 53, the counterweight 603 will rise. When the rise exceeds expectations, it means that the wire bow has become larger. At this time, the cutting efficiency is low. The staff can perform corresponding maintenance in time to restore the cutting efficiency, while effectively avoiding the breakage of the diamond wire 33.

[0028] A cutting method using a wire group winding structure includes the following steps: S1. When in use, install the wire group winding structure on the cutting machine, select the number of wire group winding structures according to needs, and arrange multiple wire group winding structures vertically and evenly on the cutting machine, so that the cutting wires on the multiple wire group winding structures together form a cutting wire network, and then transport the workpiece to be cut to the cutting line through the mobile assembly; S2, turn on the forward and reverse motor 2 and drive the winding roller 32 to rotate, so that one cutting line is in a pay-out state on the winding roller 32 as it rotates, and the other cutting line is in a take-up state on the winding roller 32 as it rotates. When the forward and reverse motor 2 continues to rotate, the two cutting lines are dynamic. At this time, the moving component continues to move the workpiece to be cut so that it contacts the cutting line; S3, after rotating a certain number of times, control the forward and reverse motor 2 to rotate in the reverse direction, so that the moving directions of the two cutting lines are changed, and the directions of the forward and reverse motor 2 are continuously and alternately changed, so that the two cutting lines can move back and forth, and reciprocating cutting of the workpiece to be cut is realized.

[0029] Among them, step S1 adopts the method of moving the workpiece to be cut toward this group of wire winding structure to achieve cutting. In specific implementation, this group of wire winding structure can also be installed on the cutting machine through a transversely movable mechanical structure according to actual needs, and then the cutting is achieved by controlling the movement of this group of wire winding structure toward the stone.

[0030] In the above-mentioned wire winding structure, only one winding roller 32 is used to simultaneously realize wire taking-up and winding. Compared with the setting of two winding rollers 32 in the prior art, the cost is effectively reduced. When multi-wire cutting is required, multiple sets of the winding structure can be set. When the diamond wire breaks during cutting, it only affects the local area, without the need for overall shutdown for maintenance, effectively reducing the impact on cutting efficiency.

[0031] The second implementation method: Based on the first embodiment, this embodiment adds a wire bow detection unit, and the rest of the parts remain the same as the first embodiment.

[0032] Figure 7-9 As shown, a line bow detection unit is also provided on the counterweight hammer 603, and the line bow detection unit includes a conical rod 71 fixedly connected to the upper end of the limit seat 63, a bearing ring 72 fixedly connected to the outer end of the conical rod 71, a detection ring 8 fixedly connected to the back plate 61, and an alarm installed at the bottom of the counterweight hammer 603. The lower end of the pulley line 604 movably passes through the detection ring 8 and is fixedly connected to the conical rod 71. The upper end of the bearing ring 72 is fixedly connected to an external pressure sensor 701, and the axis of the external pressure sensor 701 intersects with the detection ring 8. The detection ring 8 includes an outer ring body 81, an inner sensing layer 82 fixedly connected to the inner wall of the outer ring body 81, and two diaphragms 83 fixedly connected to the inner sensing layer 82. The inner wall of the outer ring body 81 has two grooves 801, and the inner walls of the two grooves 801 are both installed with internal pressure sensors 802. The internal pressure sensor 80 2 and the external pressure sensor 701 are connected to the alarm signal. During cutting, when the wire bow is normal, there is a certain distance between the conical rod 71 and the detection ring 8. When the wire bow increases abnormally, the counterweight hammer 603 will continue to rise, and then the conical rod 71 will enter the detection ring 8 and collide with the internal sensing layer 82, so that the two internal pressure sensors 802 will generate force data, and the force data are not much different. At this time, the alarm can be triggered for the first time to make it alarm. As the wire bow continues to increase, the conical rod 71 penetrates the internal sensing layer 82 and makes the carrying ring 72 gradually approach the detection ring 8 until they collide with each other, so that the external pressure sensor 701 is squeezed and generates acceptance data. At this time, the alarm can be triggered again, so as to promptly remind the staff to perform maintenance and inspection, and effectively avoid the situation where the diamond wire 33 is broken due to abnormal changes in the wire bow.

[0033] The two grooves 801 and the two diaphragms 83 are cross-distributed with each other, so that the interior of the internal sensing layer 82 can be divided into two spaces. When the thinner pulley line 604 collides with the internal sensing layer 82, the single-point collision is not enough to make the two internal pressure sensors 802 generate data with little difference. Either only one generates data, or both internal pressure sensors 802 generate data, but the difference is large, thereby effectively avoiding false alarms caused by contact between the pulley line 604 and the internal sensing layer 82.

[0034] The inner sensing layer 82 is an annular structure, and the cross-section of the inner sensing layer 82 is an inverted parallel trapezoid. The inner diameter of the upper part of the inner sensing layer 82 is consistent with the outer diameter of the upper end of the conical rod 71. When the top of the conical rod 71 moves to the upper mouth of the inner sensing layer 82, the two inner sensing layers 82 can generate force data, and the data difference is not large. The inner force of the lower end of the inner sensing layer 82 is smaller than the diameter of the connection between the conical rod 71 and the bearing ring 72, and the inner diameter of the outer ring body 81 is larger than the diameter of the connection between the conical rod 71 and the bearing ring 72 and smaller than the outer diameter of the bearing ring 72. When the bearing ring 72 reaches the detection ring 8, the external pressure sensor 701 between the two can be squeezed to generate data.

[0035] Compared with the first embodiment, this embodiment does not require manual observation of the rise of the counterweight hammer 603 to determine the wire bow condition. It can realize automatic monitoring of the wire bow and timely warn of abnormal changes, thereby improving the timeliness of detecting wire bow changes and further reducing the occurrence of diamond wire 33 breakage caused by abnormal increase of the wire bow.

[0036] In summary, only one winding roller 32 is used to simultaneously realize wire taking-up and wire winding, which effectively reduces the cost compared with the setting of two winding rollers 32 in the prior art, and when multi-wire cutting is required, multiple groups of the winding structure can be set. When the diamond wire breaks during cutting, it only affects the local area, and there is no need to shut down the entire machine for maintenance, which effectively reduces the impact on the cutting efficiency. At the same time, with the setting of the adjustment component 6, the tension of the diamond wire 33 and the wire bow during cutting can be self-adjusted, and the wire bow can be monitored at the same time, so that the user can promptly detect the problem of low cutting efficiency caused by abnormal enlargement of the wire bow, which is convenient for timely maintenance and reduces the occurrence of diamond wire 33 breakage due to continuous enlargement of the wire bow.

[0037] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
