Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wire cutting machine, in particular to a wire arranging assembly, a wire saw unit, a wire cutting machine and a wire arranging angle control method thereof. BACKGROUND

[0002] In the cutting process of the wire cutting machine, taking a slicing machine as an example, as the cutting proceeds, the wire storage amount on the wire collecting and releasing roller of the wire collecting and releasing assembly changes constantly, thereby causing the diameter of the wire collecting and releasing roller to change; in addition, in the high-speed running of the cutting wire, the tension of the cutting wire also changes. The above changes will cause the cutting wire entering and leaving the wire arranging guide wheel to deviate from the wire groove center of the wire arranging guide wheel and deviate towards the groove wall of the wire arranging guide wheel, and the cutting wire in this state is prone to rotate at high speed, thereby causing the wire net to run with shaking and causing the cutting quality to decrease. SUMMARY

[0011] Further optimization of the technical scheme of the present application, the swing compensation assembly uses the radius R of the take-up and pay-off roller at the current time and the distance L between the swing axis and the axis of the take-up and pay-off roller to construct an inverse sine function to obtain the swing angle β of the wire arranging guide wheel.

[0012] Further optimization of the technical scheme of the present application, the swing angle β of the wire arranging guide wheel is also related to the angle Q between the connecting line between the swing axis and the axis of the take-up and pay-off roller and the cutting wire led out or led into the wire arranging guide wheel when the swing angle of the wire arranging guide wheel is 0°.

[0013] Further optimization of the technical scheme of the present application, the swing angle β of the wire arranging guide wheel satisfies the following definition formula:

[0014] β=Q-arcsin(R / L);

[0015] Wherein, R is the radius of the take-up and pay-off roller of the take-up and pay-off assembly at the current time;

[0016] L is the distance between the swing axis and the axis of the take-up and pay-off roller;

[0017] Q is the angle between the connecting line between the swing axis and the axis of the take-up and pay-off roller and the cutting wire led out or led into the wire arranging guide wheel when the swing angle of the wire arranging guide wheel is 0°.

[0025] Since the pressing rod will shake at the moment of cutting start and stop, in order to reduce the shaking of the pressing rod, a band brake is arranged on the rotating shaft, and the band brake can be started before cutting starts and cutting stops, so as to reduce the shaking of the pressing rod.

[0026] Further optimization of the technical scheme of the present application, further comprises a position detection mechanism for detecting that the wire arranging guide wheel is driven by the cutting wire tension to deviate from the preset inclination angle of the pressing rod.

[0027] The position detection mechanism comprises a signal receiving device and a signal emitting device arranged on the pressing rod, and the signal receiving device receives the signal emitted by the signal emitting device to obtain the displacement amount of the wire arranging guide wheel when the pressing rod deviates from the preset inclination angle due to the cutting wire tension.

[0028] In a further optimization of the technical solution of the present invention, the signal receiving device includes a displacement sensor located below the first motor, and the signal transmitting device includes a reflector arranged parallel to the counterweight. The displacement sensor obtains the displacement of the cable guide wheel when the pressure rod deviates from the preset tilt angle due to the tension of the cutting wire caused by the light reflected by the reflector.

[0029] A further optimization of the technical solution of the present invention includes a translation module, which includes a guide rail extending along the axial direction of the take-up and untake-up rollers and a wire laying slide block disposed on the guide rail.

[0030] In a further optimization of the technical solution of the present invention, the position detection mechanism is signal-connected to the translation module, and the translation module adjusts the moving speed of the cable laying mechanism according to the displacement of the pressure rod when it is driven by the tension of the cutting wire to deviate from the preset tilt angle.

[0031] In a further optimization of the technical solution of the present invention, the cable slide includes a slider slidably disposed on the guide rail and a motor bracket connected to the slider. The first motor and the swing bracket are respectively disposed on both sides of the motor bracket. The output shaft of the first motor passes through the motor bracket and is fixedly connected to the swing bracket.

[0032] In a further optimization of the technical solution of the present invention, the translation module further includes a protective cover and a second motor and a drag chain disposed inside the protective cover. The second motor is connected to the slider to drive the slider to slide on the guide rail.

[0033] One end of the drag chain is connected to the slider, and the other end of the drag chain is fixed to the module bracket. The main cable connected to the first motor passes through the drag chain, so that it can move with the movement of the cable laying mechanism.

[0035] According to a second aspect of the present invention, a wire saw unit includes a cutting mechanism for winding a cutting wire to cut a workpiece and the aforementioned wire assembly. A tension mechanism for adjusting the tension of the cutting wire is provided between the cutting mechanism and the wire assembly. The cutting wire reciprocates between the wire take-up and unwinding assembly, the wire assembly mechanism, the tension mechanism, and the cutting mechanism in sequence to achieve cutting.

[0036] According to a third aspect of the present invention, a wire cutting machine includes the wire saw unit described above.

[0037] In a further optimization of the technical solution of the present invention, the wire cutting machine is a slicing machine.

[0038] According to a fourth aspect of the present invention, a method for controlling the wire laying angle of a wire EDM machine is provided for use in a wire laying assembly, comprising the following steps:

[0039] S1: When the cable laying mechanism deviates from the preset position range, the angle adjustment mechanism adjusts the posture of the cable laying mechanism to eliminate the deviation; and / or

[0040] S2: When the guide wheel of the wiring mechanism is pulled away from the preset tilt angle by the cutting wire, the translation module adjusts the moving speed of the wiring mechanism.

[0041] A further optimization of the technical solution of the present invention is that the angle adjustment mechanism includes a swing compensation component connected to the cable guide wheel;

[0042] In step S1, the swing compensation component drives or drives the cable guide wheel to swing around the swing axis of the swing compensation component to adjust the swing angle of the cable guide wheel so that the cutting wire and the cable laying mechanism are kept within a preset position range.

[0043] In a further optimization of the technical solution of the present invention, in step S2, the swing compensation component adjusts the swing angle of the wire guide wheel according to the change in the radius of the take-up and release roller of the take-up and release component, so that the cutting wire and the wire release mechanism are kept within a preset position range.

[0044] When the cutting line and the wire laying mechanism are within a preset position range, the axial section of the wire laying guide wheel is tangent to the circumferential surface of the take-up and release rollers.

[0045] In a further optimization of the technical solution of the present invention, the swing compensation component uses the radius R of the take-up and release rollers at the current moment and the distance L between the swing axis and the axis of the take-up and release rollers to construct an arcsine function to obtain the swing angle β of the wire guide wheel.

[0046] In a further optimization of the technical solution of the present invention, the swing angle β of the wire guide wheel is also related to the angle Q between the line connecting the swing axis and the axis of the take-up and unwind rollers and the cutting line led out or led in on the wire guide wheel when the swing angle of the wire guide wheel is 0°.

[0047] A further optimization of the technical solution of the present invention is that the swing angle β of the cable guide wheel satisfies the following definition:

[0048] β = Q - arcsin(R / L);

[0049] Where R is the radius of the take-up and untake-up rollers at the current moment;

[0050] L is the distance between the swing axis and the axis of the take-up and unwind rollers;

[0051] Q is the angle between the line connecting the swing axis and the axis of the take-up and untake-up rollers and the cutting line extending from the wire guide wheel when the swing angle of the wire guide wheel is 0°.

[0052] Further optimization of the technical solution of the present invention, step S1 includes:

[0053] S21: The position detection mechanism detects the displacement of the cable guide wheel when the pressure rod deviates from the preset tilt angle due to the tension of the cutting wire;

[0054] S22: The translation module adjusts the moving speed of the wiring mechanism according to the displacement of the pressure rod when it is driven by the tension of the cutting wire to deviate from the preset tilt angle.

[0055] In a further optimization of the technical solution of the present invention, the pressure rod has a preset tilt angle relative to the horizontal or vertical plane. When the pressure rod is within the preset tilt angle range, the counterweight on the pressure rod, the pressure rod, and the cable guide wheel are statically balanced as a whole.

[0056] In a further optimization of the technical solution of the present invention, the preset tilt angle is 45°±5°. More preferably, the preset tilt angle is 45°±0.5°.

[0057] Compared with the prior art, the advantages of the present invention are that by setting an angle adjustment mechanism, the swing angle of the wire guide wheel can be finely adjusted to follow the diameter change on the take-up and untake-down rollers, so that the wire guide wheel is always within the preset position range, thereby effectively avoiding the shaking problem during wire mesh operation, improving the stability of the cutting wire mesh, reducing the probability of wire breakage and skipping, and thus improving the cutting quality and cutting efficiency.

[0076] The invention will now be further described with reference to the accompanying drawings.

[0077] like Figures 1-5 As shown, according to a first aspect of the present invention, the present invention provides a wire laying assembly, including a wire laying mechanism 100, an angle adjustment mechanism 200 and a take-up and unwinding assembly, thus the wire laying assembly has a wire laying function and a take-up function (i.e., wire is laid out or taken up by the take-up and unwinding roller 500 of the take-up and unwinding assembly).

[0078] The cable laying mechanism 100 includes a cable laying guide wheel 110, and an angle adjustment mechanism 200 is connected to the cable laying guide wheel 110. The cable laying assembly of the present invention can adjust the posture of the cable laying guide wheel 110 according to actual working conditions to keep the cable laying mechanism within a preset position range.

[0079] The wire guide roller 110 is used to wind the cutting wire 600 (e.g., diamond wire). The take-up and unwind assembly below the wire guide roller 110 includes a take-up and unwind roller 500 for storing and releasing the cutting wire 600. During the cutting process of the wire cutting machine, there are two possible states: when the take-up and unwind assembly is used as a unwinding mechanism, the released cutting wire 600 passes through the wire guide roller 110 and enters the tension control mechanism, eventually winding into the cutting mechanism to achieve cutting; or when the take-up and unwind assembly is used as a take-up mechanism, the cutting wire wound from the cutting mechanism passes through the tension control mechanism, winds into the wire guide roller 110, and is then stored in the take-up and unwind assembly. Therefore, the desired orientation of the wire guide roller 110 is that the plane (axial section) where the wire groove of the wire guide roller 110 is located is tangent to the circumferential surface of the take-up and unwind roller 500 of the take-up and unwind assembly below it, so that the cutting wire 600 between the wire guide roller 110 and the take-up and unwind roller 500 is tangent to the circumferential surface of the take-up and unwind roller 500. When the wire guide roller 110 is in the desired posture, it will not negatively affect the tension of the cutting wire 600. However, as the amount of cutting wire stored on the take-up and unwind roller 500 changes (the cutting wire is wound on the take-up and unwind roller 500), the diameter of the take-up and unwind roller 500 will change (for example, when the cutting wire is unwound from the take-up and unwind roller 500, the diameter of the take-up and unwind roller 500 becomes smaller; conversely, when the cutting wire is wound on the take-up and unwind roller 500, the diameter of the take-up and unwind roller 500 becomes larger). Combined with changes in the tension of the cutting wire 600, the plane containing the wire groove of the wire guide roller 110 is no longer tangent to the circumferential surface of the take-up and unwind roller 500, i.e., the wire groove... When the wire guide mechanism deviates from the preset position range, the cutting line 600 between the wire guide roller 110 and the take-up / unwind roller 500 cannot maintain a tangential state with the take-up / unwind roller 500. Consequently, the cutting line entering and leaving the wire guide roller 110 deviates from the center of the wire groove (biased towards the groove wall, causing friction between the cutting line and the edge of the wire groove). Under these conditions, the cutting line 600 is prone to rotation at high speed, resulting in vibration during wire mesh operation and a decrease in cutting quality. Therefore, this invention, by setting an angle adjustment mechanism 200, can adjust the posture (swing angle) of the wire guide roller 110 to eliminate this deviation when the diameter of the take-up / unwind roller 500 changes and causes the wire guide roller 110 to deviate from the preset position range. Understandably, when the wire guide roller 110 is within the preset position range, the axial section of the wire guide roller 110 (specifically, the axial section where the wire groove of the wire guide roller 110 is located) is tangent to the circumferential surface of the take-up and undo roller 500. Since the diameter of the take-up and undo roller 500 changes during operation, the preset position range described herein should also be a changing position, depending on the diameter of the take-up and undo roller 500.

[0080] More specifically, by oscillating the cable guide wheel 110 to adjust its posture, the angle of deviation of the cable guide wheel 110 can be compensated, which helps to ensure that the cutting line 600 between the cable guide wheel 110 and the take-up / delivery roller 500 remains tangent to the take-up / delivery roller 500 (e.g., Figure 3 As shown in the figure, this design allows the cutting wire 600 to be positioned at the center of the wire groove of the wire guide wheel 110, thereby effectively avoiding the shaking problem during the operation of the cutting wire mesh, improving the stability of the cutting wire mesh, reducing the probability of wire breakage and skipping, and thus improving the cutting quality and cutting efficiency.

[0081] It is understandable that the cutting line 600 between the wire guide roller 110 and the take-up / unwind roller 500 of the take-up / unwind assembly being tangent to the take-up / unwind roller 500 means that the cutting line 600 between the wire guide roller 110 and the take-up / unwind roller 500 of the take-up / unwind assembly is tangent to the outer circumference of the take-up / unwind roller 500 on which the cutting line is wound (or unwound). Taking the take-up / unwind assembly in the unwinding state as an example, the take-up / unwind roller 500 of the unwinding assembly guides the cutting line to the wire guide roller 110. Therefore, as the cutting line is gradually used, the diameter of the take-up / unwind roller 500 gradually decreases, thereby changing the relationship between the cutting line 600 guided by the take-up / unwind roller 500 to the wire guide roller 110 and the take-up / unwind roller 500, which may result in a situation where they are not tangent. By finely adjusting the swing angle of the wire guide roller 110, the cutting line 600 led by the take-up and give-off rollers 500 of the wire feeding assembly to the wire guide roller 110 can be restored to a tangent relationship with the take-up and give-off rollers 500.

[0082] Specifically, the angle adjustment mechanism 200 includes a swing compensation component, and the point where the swing compensation component is connected to the cable guide wheel 110 is the swing axis (e.g., Figure 1 As shown in M), the swing compensation component causes the cable guide wheel 110 to swing around the swing axis to adjust the swing angle of the cable guide wheel 110.

[0083] The cutting wire 600 is sequentially wound around the wire guide roller 110 and the take-up / unwind roller 500 of the take-up / unwind assembly. The oscillation compensation assembly adjusts the oscillation angle β of the wire guide roller 110 according to the change in the radius R (or diameter D) of the take-up / unwind roller 500. The oscillation angle β of the wire guide roller 110 is within the range of -10° to +10°; preferably, the oscillation angle β of the wire guide roller 110 is within the range of -3° to +3°. Taking an oscillation range diameter of 200mm-235mm as an example, the oscillation angle can be, for example, 1° to 3°.

[0084] The angle adjustment mechanism 200 adjusts the posture (angle) of the wire guide wheel 110, ensuring that the plane of the wire groove of the wire guide wheel 110 is always tangent to the circumferential surface of the take-up and undo roller 500. This reduces the tension variation of the cutting line 600 between the wire guide wheel 110 and the take-up and undo roller, lowering the probability of the cutting line 600 breaking. The angle adjustment mechanism 200 adjusts in real time according to the parameters at the current moment, which can improve the timeliness of the wire guide wheel 110's correction, significantly reduce lag, and improve the accuracy of correction, making the effect more precise.

[0085] In some embodiments, such as Figure 6 As shown, the oscillation compensation component uses the radius R (or diameter D) of the take-up and untake-up rollers 500 at the current moment and the distance L between the oscillation axis (M) and the axis of the take-up and untake-up rollers 500 to construct an arcsine function to obtain the oscillation angle β of the wire guide roller 110. Understandably, the oscillation angle β of the wire guide roller 110 is also related to the angle Q between the line connecting the oscillation axis (M) and the axis of the take-up and untake-up rollers 500 and the cutting line 600 leading out or leading in on the wire guide roller 110 when the oscillation angle of the wire guide roller 110 is 0°.

[0086] Furthermore, the geometric model of the swing angle β of the cable guide wheel 110 is as follows: Figure 6 As shown, the swing angle β of the cable guide wheel 110 therefore satisfies the following definition:

[0087] β = Q - arcsin(R / L).

[0088] Where R is the radius of the take-up and untake-up roller 500 at the current moment, L is the distance between the swing axis M and the axis of the take-up and untake-up roller 500, and Q is the angle between the line connecting the swing axis M and the axis of the take-up and untake-up roller 500 and the cutting line 600 led out on the wire guide wheel 110 when the swing angle of the wire guide wheel 110 is 0°.

[0089] Therefore, it is understandable that the definition of the above swing angle β can also be β=Q-arcsin(D / 2L).

[0090] Taking the take-up / feed-out roller 500 for wire feeding as an example, the radius (or diameter D) of the take-up / feed-out roller 500 decreases as the cutting wire 600 on it is consumed. For example, as... Figure 6 As shown, the initial radius of the take-up and pay-off roller 500 is R1, which corresponds to the swing angle β of the wire guide roller 110 being 0°, and the angle between the line connecting the swing axis M and the axis of the take-up and pay-off roller 500 and the cutting line 600 extending from the wire guide roller 110 is Q. As the radius of the pay-off roller 500 decreases to R, the swing angle β can be calculated according to the above definition.

[0091] The diameter of the cable guide wheel 110 can be 100mm. Using a smaller diameter cable guide wheel 110 helps to reduce the inertia of the guide wheel.

[0092] In some preferred embodiments, such as Figure 1 As shown, the swing compensation assembly includes a first motor 210 and a swing bracket 220 connected to the output shaft of the first motor 210. Therefore, it can be understood that the swing axis M is the axis of the output shaft of the first motor 210.

[0093] The cable laying mechanism 100 also includes a pressure rod 120. The cable laying guide wheel 110 is rotatably connected to the swing bracket 220 via the pressure rod 120, allowing the cable laying guide wheel 110 and the swing bracket 220 to swing around the output shaft of the first motor 210 to adjust the swing angle of the cable laying guide wheel 110. Since the first motor 210 can drive the swing bracket 220 to swing or rotate in real time, it can also drive the cable laying guide wheel 110 to swing or rotate in real time. In addition, the swing bracket 220, as a connecting bridge between the first motor 210 and the pressure rod 120, enables the cable laying guide wheel 110 to swing smoothly and without jamming.

[0094] Among them, the axial direction of the output shaft of the first motor 210 is parallel to the axial direction of the take-up and untake-up rollers 500 (e.g., Figure 3 As shown in the figure, it is convenient to arrange and drive the cable guide wheel 110 and the swing bracket 220 to swing as a whole.

[0095] In addition to the above, the following situation also exists during operation: the spacing between the various turns of cutting wire 600 wound on the take-up and unwind rollers 500 is slightly different, causing the cutting wire 600 between the wire guide roller 110 and the take-up and unwind rollers 500 to not remain vertical, thus changing the tension of the cutting wire 600, reducing the stability of the cutting wire mesh, and consequently affecting the cutting quality. This invention solves the above problems through the counterweight 130 and pressure rod 120 of the wire laying mechanism 100.

[0096] For details, please continue to see Figure 1 The cable laying mechanism 100 also includes a counterweight 130, and the counterweight 130 and the cable laying guide wheel 110 are respectively located at the rotation point N of the pressure rod 120 and the swing bracket 220 (e.g., Figure 3 (as shown) on both sides.

[0097] More specifically, the swing bracket 220 includes a first plate 221 and a second plate 222, as shown below. Figure 5 As shown, the second plate 222 extends in the horizontal direction (i.e., the axial direction of the take-up and untake-off rollers 500), and the first plate 221 extends in a direction perpendicular to the horizontal direction, forming an L-shaped structure. The first plate 221 is fixedly connected to the output shaft of the first motor 210, and the pressure rod 120 is inclined and rotatably mounted on the second plate 222.

[0098] like Figure 3 , Figure 5 and Figure 8 As shown, the pressure rod 120 is rotatably connected to the second plate 222 via a rotating shaft 121, thus allowing the pressure rod 120 to rotate around the rotating shaft 121 (rotation point N). Since one end of the pressure rod 120 is connected to a cable guide wheel 110, and the other end is connected to a counterweight 130, located on opposite sides of the rotation point N, the counterweight 130 ensures that the cable guide wheel 110 and the pressure rod 120 maintain static balance. The pressure rod 120 has a preset tilt angle relative to the horizontal or vertical plane. Preferably, the preset tilt angle of the pressure rod 120 is 45° ± 5°, for example, 45°. When the pressure rod 120 is within the aforementioned preset tilt angle range, the counterweight 130, the pressure rod 120, and the cable guide wheel 110 are statically balanced as a whole. It can be understood that the preset tilt angle of the pressure rod 120 is the angle between it and the horizontal direction. When the cable guide wheel 110 and the pressure rod 120 are in static equilibrium, the force exerted by the cutting wire 600 on the cable guide wheel 110 is balanced with the reaction force exerted by the cable guide wheel 110 on the cutting wire 600. Understandably, because the cutting wire 600 has tension, it will exert a corresponding force on the cable guide wheel 110.

[0099] During normal cutting, the cutting line between the take-up / release roller 500 and the wire guide roller 110 is released from or collected into the take-up / release roller 500 in a direction perpendicular to the axis of the take-up / release roller 500 (usually vertical). When there is a deviation in the spacing of the cutting line on the take-up / release roller 500, that is, when the take-up / release roller 500 has a wire guide deviation, the cutting line between the take-up / release roller 500 and the wire guide roller 110 deviates from the vertical state and tilts. The tension of the cutting line between the take-up / release roller 500 and the wire guide roller 110 changes accordingly, and the effect on the wire guide roller 110 changes. Therefore, when the wire guide roller 110 is driven by the tension of the cutting line to deviate from the preset tilt angle, the tilt angle of the pressure rod 120 changes, thereby disrupting the static balance state of the wire guide roller 110 and the pressure rod 120. When the position of the cable guide roller 110 is adjusted, the cutting wire 600 between the cable guide roller 110 and the take-up / unwind roller 500 returns to a direction perpendicular to the axis of the take-up / unwind roller 500. The tension on the cutting wire 600 is then restored, allowing the force exerted by the cutting wire 600 on the cable guide roller 110 and the reaction force exerted by the cable guide roller 110 on the cutting wire 600 to reach equilibrium again. Consequently, the tilt angle of the pressure rod 120 returns to the preset tilt angle (e.g., 45°), and the pressure rod 120 returns to a state of static equilibrium. In other words, the pressure rod 120 has a self-balancing function. Please refer to... Figure 1 , Figure 4 and Figure 5The cable assembly of the present invention further includes a position detection mechanism 300 for detecting the position of the cable guide wheel 110 deviating from a preset tilt angle due to the tension of the cutting wire 500 causing the pressure rod 120 to deviate. The position detection mechanism 300 includes a signal receiving device 310 and a signal transmitting device 320 disposed on the pressure rod 120. The signal receiving device 310 receives the signal emitted by the signal transmitting device 320 to obtain the displacement of the cable guide wheel 110 when the tension of the cutting wire 500 causes the pressure rod 120 to deviate from the preset tilt angle.

[0100] Specifically, the signal receiving device 310 includes a displacement sensor located below the first motor 210, and the signal transmitting device 320 includes a reflector arranged parallel to the counterweight 130. The displacement sensor can calculate the displacement of the cable guide wheel 110 when it is driven by the tension of the cutting wire 500 to drive the pressure rod 120 to deviate from the preset tilt angle based on the light reflected by the reflector.

[0101] When the online cutting machine starts and stops cutting, the pressure rod 120 will shake. Therefore, in order to avoid the pressure rod 120 from shaking undesirably, the present invention solves this problem by setting a holding brake 140.

[0102] Specifically, such as Figure 3 and Figure 8 As shown, a holding brake 140 is installed on the rotating shaft 121 that rotatably connects the pressure rod 120 to the second plate 222. More specifically, please see... Figure 8 The holding brake 140 is located on the rotating shaft 121 at one end away from the cable guide wheel 110. It can apply braking force to the rotating shaft 121 to prevent the rotating shaft 121 and the pressure rod 120 connected thereto from producing undesirable swaying.

[0103] Furthermore, the holding brake 140 is controlled to start and stop by an electromagnetic switch (e.g., a solenoid valve). The electromagnetic switch is connected to a control system to receive a command to activate the holding brake 140 from the control system. Therefore, it is understood that the holding brake can be, for example, an electromagnetic holding brake, and its specific structural form can adopt existing structural forms, which will not be elaborated further in this invention.

[0104] Therefore, by providing a holding brake on the rotating shaft 121, the present invention activates the holding brake 140 before the wire cutting machine starts and stops cutting, thereby preventing undesirable shaking of the pressure rod 120. Figure 1As shown, it also includes a translation module 400, which includes a guide rail 410 extending along the axial direction of the take-up and unwind rollers 500 and a wire laying slide 420 disposed on the guide rail 410. The wire laying slide 420 is connected to the angle adjustment mechanism 200 or the wire laying mechanism 100 to drive the angle adjustment mechanism 200 and the wire laying mechanism 100 to reciprocate. As the cutting wire 600 is wound on the take-up and unwind rollers 500, it is arranged along the axial direction of the take-up and unwind rollers 500 with a certain pitch. Therefore, as the cutting wire 600 is wound (or unwound) on the take-up and unwind rollers 500, the position of the cutting wire 600 on the axial direction of the take-up and unwind rollers 500 changes. The translation module 400 drives the angle adjustment mechanism 200 and the wire laying mechanism 100 to move, so that the wire laying guide wheel 110 can follow the movement of the cutting wire 600. This makes the cutting wire 600 between the wire laying guide wheel 110 and the take-up and unwind rollers 500 perpendicular to the axial direction of the take-up and unwind rollers 500, avoiding the cutting wire 600 from tilting and breaking, and ensuring the stability of the cutting wire 600 during high-speed operation.

[0105] Furthermore, the position detection mechanism is connected to the translation module 400 via a signal group. The translation module 400 adjusts the moving speed of the wire laying mechanism 100 according to the displacement of the wire laying guide wheel 110 when the pressure rod 120 deviates from the preset tilt angle due to the tension of the cutting wire.

[0106] When the cable guide wheel 110 positions the pressure rod 120 within a preset tilt angle range, the cutting line 600 within the plane of the cable groove of the cable guide wheel 110 remains vertical. Figure 7 As shown by the solid line. When the spacing (pitch) between the cutting wires 600 wound on the take-up and untake-off rollers 500 increases or decreases, the cutting wires 600 wound onto the wire guide rollers 110 will tilt to the left or right, respectively, as shown in the diagram. Figure 7 As shown by the dashed line, the tension of the cutting wire 600 increases or decreases, thereby pulling the wire guide wheel 110 to rotate clockwise or counterclockwise. Due to the tension of the cutting wire, the wire guide wheel 110 causes the pressure rod 120 to deviate from the preset tilt angle. At this time, the distance d between the pressure rod 120 and the displacement sensor will decrease or increase. This change can be detected by the position detection mechanism. The signal transmitting device and reflector of the position detection mechanism can obtain the displacement of the wire guide wheel 120 at this time and feed it back to the translation module. The translation module obtains the horizontal displacement of the wire guide wheel 110 after trigonometric function conversion and adjusts the moving speed of the wire guide wheel 110 accordingly (slowing down or speeding up) so that the cutting wire 600 remains vertical (perpendicular to the axis of the take-up and unwinding roller 500). The wire guide wheel 110 then returns the pressure rod 120 to within the preset tilt angle range.

[0107] like Figure 5As shown, the cable routing slide 420 includes a slider 421 slidably mounted on a guide rail 410 and a motor bracket 422 connected to the slider 421. A first motor 210 and a swing bracket 220 are respectively mounted on both sides of the motor bracket 422. The output shaft of the first motor 210 passes through the motor bracket 422 and is fixedly connected to the swing bracket 220. Therefore, when the slider 421 slides on the guide rail 410, it can drive the cable routing mechanism 100 and the angle adjustment mechanism 200 to reciprocate to realize cable routing.

[0108] The translation module 400 also includes a protective cover 450 and a second motor 430 and a cable chain 440 disposed within the protective cover 450. The protective cover 450 reduces dust ingress to prevent damage to the translation module 400. The second motor 430 can be connected to a displacement sensor signal, thereby adjusting its rotational speed based on the displacement of the cable guide wheel 110 when it is pulled by the cutting wire and causes the pressure rod 120 to deviate from a preset tilt angle, thus regulating the moving speed of the cable laying mechanism 100.

[0109] The second motor 430 is connected to the slider 421 to drive the slider 421 to slide on the guide rail 410. One end of the cable carrier 440 is connected to the slider 421, and the other end of the cable carrier 440 is fixed to the module bracket. The cable carrier 440 carries the main cable connected to the first motor 210 and the signal line connected to the displacement sensor, etc., so that these cables can move with the movement of the cable laying mechanism 100.

[0110] A removable cover plate 470 is provided on one side of the protective cover 450 (e.g., Figure 2 As shown), it is easy to install and remove. Figure 1 As shown, the protective cover 450 is also equipped with a limit switch 460 to limit the extreme positions of the slider 421. There can be two limit switches 460, which can limit the extreme positions of the slider 421 to the left and right respectively.

[0111] According to a second aspect of the present invention, the present invention provides a wire saw unit, which includes a cutting mechanism for winding a cutting wire to cut a workpiece and the above-described wire assembly, wherein a tension mechanism for adjusting the tension of the cutting wire is provided between the cutting mechanism and the wire assembly.

[0112] The cutting wire 600 reciprocates sequentially between the take-up and untake-down assembly, the wire assembly, the tension mechanism, and the cutting mechanism to achieve cutting. For example... Figure 3As shown, the take-up and unwinding assembly can be located below the wire assembly. The take-up and unwinding assembly includes take-up and unwinding rollers 500 for winding or unwinding the cut wire 600 (diamond wire). The take-up and unwinding assembly includes a take-up assembly and a unwinding assembly. The unwinding assembly guides the cut wire 600 into the wire assembly, and conversely, the take-up assembly receives the cut wire 600 exiting the wire assembly. That is, the working processes of the take-up assembly and the unwinding assembly are reverse processes.

[0113] A tension control mechanism (not shown) continuously applies a stable tension value to the cutting wire, ensuring that the entire cutting wire is stretched and taut during operation. Specifically, the tension wheel assembly includes a tension arm, a tension wheel, a guide wheel rotation assembly, and a tension drive motor for moving the tension wheel. The tension drive motor is fixed to the winding chamber frame, and the tension wheel is connected to the tension swing arm. Two limit posts are symmetrically arranged at both ends of the tension swing arm to limit the swing range of the tension swing arm. The tension wheel effectively pulls the diamond wire of the wire mesh routing mechanism, ensuring that the wire mesh is always at the optimal tension.

[0114] Other components and parts of the cutting mechanism, wire take-up and untake-up assembly, and tension mechanism not mentioned in this invention can adopt existing structures, and will not be described in detail here.

[0115] According to a third aspect of the present invention, a wire cutting machine is provided, comprising the wire saw unit and cutting assembly described above. Preferably, the wire cutting machine of the present invention is a slicing machine.

[0116] Other components and / or parts in the wire saw unit and wire EDM machine may adopt existing structural forms, which will not be described in detail in this invention.

[0117] According to a fourth aspect of the present invention, the present invention provides a method for controlling the wire laying angle of the wire cutting machine described above, comprising the following steps:

[0118] S1: When the cutting line 600 deviates from the preset position range from the wiring mechanism 100, the angle adjustment mechanism 200 adjusts the posture of the wiring mechanism 100 to eliminate the deviation.

[0119] Specifically, the swing angle of the wire guide wheel 110 relative to the take-up and unwind roller 500 of the take-up and unwind assembly is adjusted by the angle adjustment mechanism 200, so that the plane where the wire groove of the wire guide wheel 110 is located is always tangent to the circumferential surface of the take-up and unwind roller 500, that is, the cutting line 600 between the wire guide wheel 110 and the take-up and unwind roller 500 of the take-up and unwind assembly is kept tangent to the circumferential surface of the take-up and unwind roller 500.

[0120] Specifically, the swing compensation component causes the cable guide wheel 110 to swing around the swing axis M to adjust the swing angle β of the cable guide wheel 110, so that the cable laying mechanism 100 is kept within a preset position range.

[0121] The swing compensation component adjusts the swing angle of the wire guide wheel 110 relative to the wire take-up roller 500 based on the radius of the take-up roller 500 of the take-up and take-up assembly at the current moment and the distance between the swing axis M and the axis of the take-up roller 500.

[0122] The swing angle β of the cable guide wheel 110 can be calculated according to the definition above, and will not be repeated here.

[0123] S2: When the guide wheel 110 of the wiring mechanism 100 is pulled by the cutting wire and the pressure rod 120 deviates from the preset tilt angle, the translation module 400 adjusts the moving speed of the wiring mechanism 100.

[0124] Specifically, step S2 includes the following sub-steps:

[0125] S21: The position detection mechanism detects the displacement of the cable guide wheel 110 when the pressure rod 120 deviates from the preset tilt angle due to the tension of the cutting wire;

[0126] S22: The translation module 400 adjusts the moving speed of the cable laying mechanism according to the displacement of the cable laying guide wheel 110 when it deviates from the preset tilt angle.

[0127] The pressure rod 120 has a preset tilt angle relative to the horizontal or vertical plane, which is 45°±5°. Preferably, the preset tilt angle of the pressure rod 120 is 45°±5°, for example, 45°. When the pressure rod 120 is within the preset tilt angle range, the counterweight 130, the pressure rod 120, and the cable guide wheel 110 are statically balanced as a whole.

[0128] It should be noted that there is no specific order between steps S1 and S2. Step S1 can be performed first, or step S2 can be performed first, or steps S1 and S2 can be performed simultaneously.

[0129] Although the invention has been described with reference to preferred embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner as long as there is no structural conflict. The invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
