For cutting of hard and brittle materials, wire cutting machines have become the mainstream products on the market with their absolute advantages in terms of slice output rate, cutting efficiency, production cost, and environmental protection. When the wire cutting machine is working, the wire net composed of cutting wires wound on the main roller assembly cuts the workpiece to be cut. For example, when the wire cutting machine is running, the workpiece to be cut moves in the vertical direction, and the wire net cuts the workpiece to be cut into multiple slices during high-speed rotation.

The workpiece to be cut is usually first fixed on the crystal tray, and then the crystal tray with the workpiece to be cut is installed on the feeding mechanism to fix the workpiece to be cut in the feeding direction. In a specific example, the workpiece to be cut is fixed to the crystal tray by bonding, and the crystal tray is clamped by a movable support provided on the feeding mechanism. The clamping degree of the crystal tray directly affects the cutting accuracy and cutting quality of the wire cutting machine. Therefore, how to detect whether the crystal tray is clamped is crucial for the subsequent cutting process.

It should be noted that, although the specific movement mode of the moving part 2 is not introduced in the above embodiment, this does not mean that the present application cannot be implemented. On the contrary, those skilled in the art can use any method in the prior art to realize the movement of the moving part 2.

On the premise of being able to detect the clamping degree of the crystal support 3, those skilled in the art may adjust the number and position of the detection channels. For example, only the first detection channel 111 may be provided on the mounting seat 1 to detect the clamping degree of the top of the crystal support 3, and the second detection channel 112 may be omitted. For another example, the first detection channel 111 may also be a channel for detecting the clamping degree of the side of the crystal support 3, and the corresponding second detection channel 112 is a channel for detecting the clamping degree of the top surface of the crystal support 3. For another example, under the premise of setting up the first detection channel 111 and the second detection channel 112 at the same time, the number of the first detection channel 111 and the number of the second detection channel 112 can be adjusted by those skilled in the art, as long as there is at least one of each.

The action principle of the present application is described below in conjunction with Figures 4 and 5. When the crystal support 5 is in a clamped state, when the crystal support 5 needs to be loosened, the hydraulic pump is controlled to work, the hydraulic oil is compressed, and the oil pressure is used to push the four push rods 42 to extend. The push rods 42 push the movable part 2 to move in the horizontal direction and away from the crystal support 5, thereby loosening the crystal support 5. At this time, the three T-shaped rods slide synchronously in the horizontal direction under the movement of the movable part 2, the first bolt 33 moves into the adjustment hole 121, and the disc spring is squeezed by the cap end of the T-shaped rod to store elastic potential energy. When the crystal support 5 is in an unclamped state, when the crystal support 5 needs to be clamped, the hydraulic pump is controlled to suck the hydraulic oil. At this time, the elastic potential energy stored in the disc spring is released, and the three T-shaped rods slide toward the bottom of the first mounting hole 111 under the elastic force of the disc spring. The movable part 2 moves synchronously in the horizontal direction under the drive of the T-shaped rod and gradually approaches the crystal support 5, thereby finally clamping the crystal support 5. At this time, the four push rods 42 retract into the cylinder body 41 under the push of the movable part 2. When When the clamping force of the moving member 2 needs to be adjusted, a tool is used to pass through the adjustment hole 121 to adjust the tightness of the first bolt 33 to adjust the preload force of the disc spring.

In the above preferred embodiment, the first push part 3 and the second push part 4 are both connected to the vertical section of the first plate body, which can directly drive the moving part 2 to move and improve the movement stability. The first push part 3 adopts an elastic member 31, and the elastic potential energy release of the elastic member 31 can be used to drive the moving part 2 to move along the first direction. The structure is simple and the effect is good. The elastic member 31 adopts a disc spring, and the characteristics of the disc spring with large load and short stroke can be used to improve the clamping effect and clamping stability of the crystal support 5. By abutting the elastic member 31 between the first connecting member 32 and the cover plate 14, the elastic potential energy release of the first elastic member 31 can be used to achieve the clamping of the crystal support 5, without the need to introduce an additional power mechanism, and the setting method is simple and practical. By setting the first connecting member 32 to be slidably connected to the first mounting hole 111 set on the mounting seat 1, the movement of the moving part 2 can be guided, and the movement stability and clamping fit accuracy can be improved. By adopting the first bolt 33 from the second side of the cover plate 14 through the connecting hole and the T-bar screw connection, the installation between the T-bar and the moving part 2 is convenient.

By setting the push rod 42 in the second push part 4, the push rod 42 can be used to push the moving part 2 relative to the cylinder body 41 to move, so as to realize the movement of the moving part 2 in the opposite direction of the first direction. By setting the cylinder body 41 in the second mounting hole 112, the layout space of the second push part 4 can be saved, and the operation stability of the push rod 42 can be improved. In addition, by setting the cylinder body 41 in the second mounting hole 112, the push rod 42 can be used to push the moving part 2 to realize the loosening of the crystal support 5, thereby improving the loosening effect of the crystal support. By setting the cover plate 14, the cylinder body 41 is abutted against the cover plate 14, and the connection stability of the cylinder body 41 can be improved. By setting the power channel 113 in the mounting seat 1, the power source can be guided into the cylinder body 41 by the power channel 113, so that the push rod 42 can be pushed by the power source, so that the push rod 42 can continuously output a stable driving force. In addition, combined with the first push part 3, the automatic control of the clamping and loosening process of the crystal support 5 can be realized, saving time and effort. The power channel 113 is arranged in the mounting seat 1, and the mechanism setting can be simplified to avoid the influence of the complex structure on the assembly of the crystal holder 5. By opening a through hole on the mounting seat 1, the processing of the main channel 1131 is facilitated. By arranging the oil pipe 8 on the delivery hole, the connection between the main channel 1131 and the power source is facilitated.

The upper part of the side walls extending along the length direction of the box body 1 is bent outward to form an outward expansion section, so that the opening 101 is V-shaped; support frames 8 are respectively provided on the two side walls extending along the width direction of the box body 1, and a fixing block 9 is fixed on the outer side wall of the support frame 8 away from the box body 1, and the debris box can be installed on the wire cutting machine through the fixing block 9. Two guide plates 2 are provided at the opening 101, and the two guide plates 2 are both provided along the length direction of the box body 1 corresponding to the outward expansion section. The two guide plates 2 are both pivotally connected to the top edges of the two side walls extending along the width direction of the box body 1, so that the two guide plates 2 can rotate relative to each other. The guide plate 2 includes a first plate segment 201 and a second plate segment 202. The first plate segment 201 is pivotally connected to the box body 1. The second plate segment 202 extends along the first plate segment 201 in the width direction of the box body 1. One end of the second plate segment 202 extends outward along its length direction to form a first extension segment 203. The other end of the second plate segment 202 extends outward along its length direction to form a second extension segment 204. The guide plate 2 formed by the first plate segment 201, the second plate segment 202, the first extension segment 203 and the second extension segment 204 is T-shaped, and the guide plate 2 is an integrally formed structure. Through such an arrangement, the first plate segment 201 of the guide plate 2 can be pivotally connected to the box body 1, the first extension segment 203 can cooperate with the limit rod 4 to limit the guide plate 2 from pivoting upward when the guide plate 2 pivots upward, and the second extension segment 204 can abut against the top plate 14 thereon when the feeding mechanism descends. The top plate 14 applies a downward force to the second extension segment 204, so that the guide plate 2 can pivot downward, and at the same time does not affect the second plate segment 202 of the guide plate 2 from receiving the cutting liquid, thereby forming a liquid storage space 12 with the material 10 to be cut.

Referring to FIG21 , two limit rods 4 are arranged on the side wall extending along the width direction of the box body 1, and the two limit rods 4 correspond to the guide plate 2 respectively, and are arranged on the side corresponding to the first extension section 203 respectively. When the guide plate 2 pivots upward, the limit rod 4 can abut against the first extension section 203 to limit the guide plate 2 from pivoting upward, while not affecting the cutting of the material 10 to be cut. Referring to FIG21 , the guide plate 2 is pivotally connected to the box body 1 through the guide rod 3, and the guide rod 3 is columnar. A connecting groove is provided in the middle part of the outer peripheral side surface of the guide rod 3, and the guide plate 2 is connected in the connecting groove, so that the guide plate 2 can pivot under the action of the guide rod 3. Referring to FIG. 21 again, both ends of the guide rod 3 are pivotally connected to the box body 1 through the first limit block 5. The first limit block 5 is a rectangular parallelepiped. The first limit block 5 is screwed on the side wall of the box body 1 extending along the width direction thereof. A connecting hole is provided on the first limit block 5. The free end of the guide rod 3 can be inserted into the connecting hole, so that the guide rod 3 can be pivotally arranged on the first limit block 5. A second limit block 6 is sleeved and fixed on the part of the guide rod 3 away from the first limit block 5. The outer peripheral side wall of the second limit block 6 is cylindrical. The second limit block 6 is arranged close to the connecting groove. A torsion spring 7 is sleeved on the guide rod 3 between the first limit block 5 and the second limit block 6. The two ends of the torsion spring 7 are respectively connected to the first limit block 5 and the second limit block 6, so that the torsion spring 7 can twist and store force when the guide plate 2 pivots downward. When the force applied to the guide plate 2 disappears, the torsion spring 7 releases its stored force, so that the guide plate 2 can pivot upward.

The present application also provides a cutting fluid system, which is the spray mechanism and the debris box in the above embodiment.

The roller assembly is described below with reference to Figures 22 to 31. As shown in Figure 22, the existing roller assembly includes a roller 1, a pull rod 2, a first bearing box 3 and a second bearing box 4. One end of the roller 1 is connected to the first rotating shaft 31 of the first bearing box 3, and the other end is connected to the second rotating shaft 41 of the second bearing box 4. The end of the first rotating shaft 31 away from the roller 1 extends out of the first bearing box 3 and is connected to the motor 8 through a coupling 7. A first hole 121 is provided on the roller 1, and a pull rod 2 is inserted into the first hole 121. A first axial hole 32 is provided at the end of the first rotating shaft 31 close to the roller 1, and one end of the pull rod 2 is screwed into the first axial hole 32. A second axial hole is provided on the second rotating shaft 41, and the pull rod 2 is away from the first bearing One end of the box 3 extends out of the first hole 121 and the second shaft hole in turn, and the pull rod 2 extending out of the second shaft hole is axially locked by a nut 561. With such a structural arrangement, during the operation of the wire cutting machine, the motor 8 drives the first rotating shaft 31 to rotate at high speed through the coupling 7. Since the first rotating shaft 31 is connected to the roller shaft 1 by transmission, and the roller shaft 1 is connected to the second rotating shaft 41 by transmission, the roller shaft 1 and the second rotating shaft 41 rotate synchronously, thereby driving the diamond wire 6 wound on the roller shaft 1 to rotate at high speed to achieve cutting of the material to be cut. However, since the roller shaft assembly does not have a cooling function, during the cutting process of the wire cutting machine, the temperature of the roller shaft 1 gradually increases, which increases the thermal deformation of the roller shaft 1. The increase in the thermal deformation of the roller shaft 1 will lead to a decrease in the cutting accuracy of the wire cutting machine, a decrease in the quality of the cut material, and even cause the diamond wire 6 wound on the roller shaft 1 to break.

As shown in Figures 23-25, the roller assembly of the present application includes a roller 1 and a pull rod 2, and the roller 1 is provided with a first channel 121 and a second channel 13; the pull rod 2 is at least partially inserted in the first channel 121, and a first channel 21 is provided in the pull rod 2, and a liquid inlet 22 and a liquid outlet 23 connected to the first channel 21 are respectively provided on the pull rod 2; the liquid inlet 22 is connected to the outlet of the cutting liquid supply device, the liquid outlet 23 is connected to the first end of the second channel 13, and the second end of the second channel 13 is connected to the inlet of the cutting liquid supply device. By inserting a pull rod 2 into the first channel 121 on the roller 1, a first channel 21 and a liquid inlet 22 and a liquid outlet 23 connected to the first channel 21 are arranged in the pull rod 2, so that the cutting liquid in the cutting liquid supply device can flow into the first channel 21 through the liquid inlet 22, and then flow into the second channel 13 through the liquid outlet 23, and the cutting liquid in the second channel 13 flows back to the cutting liquid supply device. This circulation can cool the roller 1 and reduce the temperature of the roller 1 during the cutting process, thereby reducing the thermal deformation of the roller 1 during high-speed cutting, thereby improving the cutting accuracy of the wire cutting machine and the cutting quality of the cutting material, and avoiding the problem of broken wire 6.

There is a gap between the outer wall of the tie rod 2 and the inner wall of the second axial hole, which serves as the third channel 42. There is a gap 533 between the outer wall of the tie rod 2 and the inner wall of the third axial hole. A through hole 531 connected to the gap is radially opened on the outer peripheral side of the third rotating shaft 51.

At this time, the second plug 5171 is pulled out so that the cutting fluid in the rotary joint assembly 5 can flow out through the drain port.

In conjunction with Figures 22-31, the cooling principle of the roller assembly during high-speed rotation is as follows: the cutting liquid is discharged from the outlet of the cutting liquid supply device, flows into the second inner cavity 57 in the rotary joint assembly 5 through the liquid injection port 521, and then flows into the first channel 21 in the pull rod 2 through the liquid inlet 22 on the pull rod 2. The cutting liquid in the first channel 21 flows into the first axial hole 32 of the first bearing box 3, and then flows into the second channel 13 through the radial channel 34 and the third channel 33. The cutting liquid in the second channel 13 flows into the gap 533 between the pull rod 2 and the rotary joint assembly 5 through the gap between the pull rod 2 and the second bearing box 4 in turn. Since the gap 533 is connected to the first inner cavity 532 through the through hole 531, the cutting liquid can pass through the first inner cavity 532 and the return liquid port 522 in turn through the through hole 531 and flow back to the cutting liquid supply device. This cycle is used to achieve cooling of the roller assembly during high-speed rotation.

The present application also provides a cutting assembly, which includes the roller assembly of the above technical solution.

The wire cutting machine includes a base 1, a cutting assembly 2, a liquid circuit assembly 3, a winding area assembly 4, an electric control cabinet 5 and a liquid storage part 6. The cutting assembly 2, the liquid circuit assembly 3 and the winding area assembly 4 are fixedly mounted on the base 1, and the electric control cabinet 5 is mounted on the top upper side of the winding area assembly 4. Among them, the cutting assembly 2 is arranged on the top surface of the base 1 and is located at the first end of the top surface along its length direction (the lower right end of the base 1 in FIG. 32 ), the liquid circuit assembly 3 is arranged on the top surface of the base 1 and is located at the second end of the top surface along its length direction (the upper left end of the base 1 in FIG. 32 ), and the winding area assembly 4 is arranged on the top surface of the base 1 and is located between the cutting assembly 2 and the liquid circuit assembly 3. After installation, a part of the liquid circuit assembly 3 extends from the second end of the base 1 along its length direction, so that a receiving space is formed between the part of the liquid circuit assembly 3 extending from the second end of the base 1 and the installation surface of the whole machine, and a part of the liquid storage part 6 is located in the receiving space. Specifically, referring to FIG34 , the base 1 is a rectangular frame structure formed by integral casting, and the frame structure includes a first frame 11, a second frame 12, a third frame 13, a fourth frame 14, and two inner frames 15.

In actual design, the length of the base 1 can be intentionally designed to be smaller than the sum of the length of the cutting assembly 2, the liquid circuit assembly 3 and the winding area assembly 4 in the base length direction, so that a holding space is formed below the liquid circuit assembly 3 after installation. After molding, the extension direction of the first frame 11 and the third frame 13 is the length direction of the base 1, and the extension direction of the second frame 12 and the fourth frame 14 is the width direction of the base 1. In addition, the bottom surface of the base 1 is also provided with a plurality of adjustment pads 16. In this application, six adjustment pads 16 are provided, and three are provided on the bottom surfaces of the first frame 11 and the third frame 13. By setting the base 1 as a frame structure, and the frame structure includes the first frame 11, the second frame 12, the third frame 13 and the fourth frame 14 connected end to end, the force of the base 1 is more balanced. Specifically, in the prior art, since the liquid storage part 6 is arranged below the cutting assembly 2, in order to facilitate the movement of the liquid storage part 6 to the bottom of the cutting assembly 2, the base 1 is usually arranged as a U-shaped open structure at the end where the cutting assembly 2 is located. This arrangement makes the forces on both ends of the base 1 unbalanced, and it is necessary to consider strengthening the structure of the U-shaped open structure during the design process. However, the base 1 of the present application is a closed frame structure, and the forces on each part of the frame structure are more balanced, and the whole machine runs more smoothly. By arranging a plurality of adjustment shims 16 on the bottom surface of the base 1, on the one hand, the adjustment shims 16 can be used to adjust the horizontality of the whole machine, and on the other hand, during transportation, the height of the adjustment shims 16 can be adjusted to make the whole machine in the lowest state for easy transportation.

In the preferred technical solution of the above-mentioned crystal tray clamping detection method, according to the judgment result, determining the clamping state of the crystal tray further includes: if the real-time air pressure value is greater than or equal to the preset air pressure threshold, then determining that the crystal tray is in a clamped state; if the real-time air pressure value is less than the preset air pressure threshold, then determining that the crystal tray is in an unclamped state. Specifically, if the real-time air pressure value is greater than or equal to the preset air pressure threshold, it proves that there is no gas leakage in the first detection channel and the second detection channel, or only a small leakage, at this time, it is considered that the top surface and the side surface of the crystal tray are clamped. On the contrary, if the real-time air pressure value is less than the preset air pressure threshold, it proves that there is at least one gas leakage in the first detection channel and the second detection channel, at this time, it is considered that at least one of the top surface and the side surface of the crystal tray is not clamped.

In the preferred technical scheme of the above-mentioned crystal tray clamping detection method, the crystal tray clamping detection method also includes: when the crystal tray is in an unclamped state, an alarm message is issued; when the crystal tray is in a clamped state, a clamped message is issued or no operation is performed. For example, when the real-time air pressure value is less than the preset air pressure threshold, the crystal tray is in an unclamped state. If the subsequent process is continued at this time, it is easy to affect the cutting accuracy and cutting quality. Therefore, it is necessary to issue an alarm message in time to remind the staff that the crystal tray is in an unclamped state. In this application, the alarm message can be sound/light information or text information. For example, the control device emits an alarm sound, controls the alarm light to flash, and controls the operation screen to pop up text information. On the contrary, when the real-time air pressure value is greater than or equal to the preset air pressure threshold, the crystal tray is in a clamped state. At this time, the operation of the subsequent process can be continued, and the staff can be reminded that the crystal tray has been tightened, or no prompt can be issued to achieve non-sensing detection. When it is necessary to remind the staff, sound/light information or text information can be issued. For example, the control device sends a voice message of "the crystal tray is clamped", the green light on the control device turns on, and a pop-up window on the control operation screen displays the text that the crystal tray is clamped. By sending an alarm message when the crystal tray is in an unclamped state, the staff can be prompted to adjust the clamping degree of the crystal tray in time, so that the subsequent processes can be implemented smoothly.
