Description

Technical Field

[0001] The present application relates to the field of wire cutting technology, and in particular to a protective device and a stone wire cutting machine. Background Art

[0002] Wire EDM is a machining method that uses a high-speed reciprocating cutting wire, moving relative to the workpiece (such as photovoltaic silicon rods, semiconductors, silicon carbide, sapphire, magnetic materials, etc.) to cut the workpiece. During the wire EDM process, liquid is sprayed on the cutting area to reduce the temperature and prevent excessive temperatures from affecting the performance and quality of the workpiece.

[0003] However, the sprayed cutting fluid can easily splash out from the cutting area, contaminating the ground and even causing injuries. To prevent injuries from splashing cutting fluid, a protective shield is generally installed around the wire saw. However, existing protective shields are generally integral structures, and the main roller of the cutting unit in the cutting chamber needs to be replaced regularly, which makes it inconvenient to replace the main roller. Utility Model Content

[0004] The embodiments of the present application provide a protective device and a stone wire cutting machine, which can effectively prevent the cutting fluid from splashing and facilitate the maintenance of the cutting unit.

[0005] In the first aspect, an embodiment of the present application provides a protective device, which is used for a stone wire cutting machine. The stone wire cutting machine includes a cutting chamber frame and a cutting unit. The cutting unit is arranged in a cutting chamber enclosed by the cutting chamber frame. The protective device includes a side door assembly and a top door assembly. The side door assembly is arranged on the side of the cutting chamber frame to prevent the cutting fluid from splashing out from the side of the cutting chamber when the cutting unit is working; the top door assembly is arranged on the top surface of the cutting chamber frame, and the top door assembly is used to prevent the cutting fluid from splashing out from the top of the cutting chamber when the cutting unit is working; wherein the top door assembly has an open state and a closed state, and the top door assembly is used to switch from a closed state to an open state when the main roller in the cutting unit is maintained and replaced.

[0006] In this solution, the side door assemblies and the top door assembly are arranged. The side door assemblies are arranged around the cutting chamber frame, forming a relatively closed protective space around the cutting unit, preventing cutting fluid from splashing out from the sides of the cutting chamber. The top door assembly is arranged at the top of the cutting chamber frame, providing a protective function for the top of the cutting unit, preventing cutting fluid from splashing out from the top of the cutting chamber. Furthermore, the top door assembly has an open state and a closed state. Therefore, when the main roller of the cutting unit needs to be maintained or replaced, only the top door assembly needs to be opened, providing an operating window for replacing the main roller. The main roller can then be removed from the operating window formed by the opening of the top door assembly for replacement, thereby facilitating maintenance work on the main roller of the cutting unit.

[0007] In some embodiments, the top door assembly includes a top door frame and a top panel door. The top door frame is installed on the top of the cutting chamber frame. One side of the top panel door is pivotally connected to the top door frame, and the other side of the top panel door is mounted on the top door frame. A handle is provided on the top panel door.

[0008] In the above technical solution, one side of the top door is pivotally connected to the top door frame, and the other side is placed on the top door frame. In this way, when the top door needs to be opened, the operator acts on the handle to flip the top door outward around one side of the hinge axis. The top door switches from a closed state to an open state, exposing the operation window, which is convenient and quick to operate.

[0009] In some embodiments, the top panel door includes a first top panel door, a second top panel door and an intermediate panel. The first top panel door and the second top panel door are spaced apart along the length direction of the top door frame. The intermediate panel is arranged between the first top panel door and the second top panel door.

The intermediate panel is detachably connected to the top door frame.

[0010] In the above technical solution, the top panel door adopts a two-section split design, comprising a first top panel door and a second top panel door. This makes a single top panel door lighter, and compared to opening the entire top panel door, opening the first top panel door or the second top panel door in sequence is more labor-saving. Furthermore, when it is necessary to observe the status of the main roller of the cutting unit, it is not necessary to completely open the entire top panel door; only the first top panel door or the second top panel door is required, making the operation more convenient. By detachably connecting the middle panel to the top door frame, the first top panel door, the second top panel door, and the middle panel can be completely opened, exposing the operating window of the top door frame, which is beneficial for the maintenance and replacement of the main roller in the cutting unit.

[0011] In some embodiments, there are two top door assemblies, and the two top door assemblies are respectively located on one side above the two main rollers of the cutting unit.

[0012] In the above technical solution, by setting the number of top door assemblies to two, the two top plate door assemblies can be respectively set to correspond to the positions of the left and right main rollers of the cutting unit. When the main roller of the cutting unit needs to be replaced, it is only necessary to open the corresponding top plate door assembly.

[0013] In some embodiments, the side door assembly includes a winding chamber door, which is arranged on both sides of the first direction of the cutting chamber frame. The winding chamber door includes a first frame and a double-leaf door, which is installed in the winding area of ​​the cutting chamber frame through the first frame. An observation window is provided on the double-leaf door, and the first direction is perpendicular to the vertical direction.

[0014] In the above technical solution, the winding chamber door is installed in the winding area of ​​the cutting chamber frame, which can block the cutting fluid from the side of the cutting chamber in a first direction. The winding chamber door adopts a bi-directional door design, which takes up less space when opening and closing, making it more convenient to open and close the door. The bi-directional door is provided with an observation window, which facilitates the staff to observe the wiring status of the winding area through the observation window.

[0015] In some embodiments, the winding room door further includes an inspection window, the first frame has a first end away from the ground, the first end is provided with an opening, the inspection window closes the opening, and there is a distance between the opening and the end surface of the first end.

[0016] In the above technical solution, by providing an inspection window, the inspection window can be opened to facilitate maintenance of the winding area of ​​the cutting unit, which is beneficial for replacing the winding and unwinding rollers and other lines.

[0017] In some embodiments, the side door assembly further includes a rolling shutter door and a water collecting trough. The rolling shutter door is arranged on both sides of the second direction of the cutting chamber frame. The rolling shutter door is used to prevent the cutting fluid from splashing out from the front and back sides of the cutting chamber when the cutting unit is working. The second direction, the first direction and the vertical direction are perpendicular to each other; the water collecting trough is arranged below the shutter door, and the water collecting trough is used to receive the cutting fluid dripping from the rolling shutter door.

[0018] In the above technical solution, the rolling shutter door shields the front and back of the cutting chamber, preventing cutting fluid from splashing out from the front and back. When maintenance is required, the shutter door can be opened to meet the needs. After maintenance is completed, the shutter door is closed to protect both sides of the cutting chamber from the second direction. Furthermore, a water trough below the shutter door collects dripping cutting fluid, preventing it from spilling and improving the working environment.

[0019] In some embodiments, the stone wire cutting machine includes a base, which is used to support the cutting chamber frame; the base includes multiple columns and connecting beams, the lower ends of the multiple columns are connected to the foundation, the connecting beams are used to connect the multiple columns into a whole, and the cutting chamber frame is arranged at one end of the multiple columns away from the foundation; the protective device also includes an operating platform, which is arranged around the bottom outer peripheral side of the cutting chamber frame, and the operating platform is used to provide a working space for the operator.

[0020] In the above technical solution, the cutting chamber frame is arranged on the top of the column of the base, and the lower end of the column is connected to the base, that is, there is a height difference between the cutting chamber frame and the foundation in the height direction. By arranging an operating platform on the outer peripheral side of the bottom of the cutting chamber frame, the operating platform can provide the operator with a working space for cutting chamber maintenance, which is convenient for the operator to perform maintenance operations on the cutting chamber.

[0021] In some embodiments, the operating platform includes a platform frame and a guardrail. The platform frame is connected to the cutting chamber frame, and the guardrail is arranged on a side of the platform frame away from the cutting chamber frame.

[0022] In the above technical solution, by arranging a guardrail on the platform frame, the guardrail can provide safety protection for the operator when the operator is walking or working on the operating platform, thereby preventing the operator from falling off the operating platform.

[0023] In some embodiments, at least one diagonal brace is provided between the platform frame and each column.

[0024] In the above technical solution, since the platform frame is directly connected to the cutting chamber frame, the platform frame is a cantilever beam structure. By arranging diagonal braces between the platform frame and the columns, the diagonal braces can provide reinforcement for the platform frame, so that the platform frame can be more firmly installed on the cutting chamber frame, thereby improving the installation stability of the operating platform.

[0042] Example

[0043] The embodiment of the present application provides a protective device, which is used for a stone wire cutting machine. Please refer to Figure 1 、 Figure 2 and Figure 3The stone wire cutting machine includes a cutting chamber frame 300 and a cutting unit. The cutting unit is arranged in a cutting chamber enclosed by the cutting chamber frame 300. The protective device 100 includes a side door assembly 10 and a top door assembly 20. The side door assembly 10 is arranged on the side of the cutting chamber frame 300 to prevent the cutting fluid from splashing out from the side of the cutting chamber when the cutting unit is working; the top door assembly 20 is arranged on the top surface of the cutting chamber frame 300, and the top door assembly 20 is used to prevent the cutting fluid from splashing out from the top of the cutting chamber when the cutting unit is working; wherein, the top door assembly 20 has an open state and a closed state, and the top door assembly 20 is used to switch from a closed state to an open state when the main roller in the cutting unit is maintained and replaced.

[0044] In this solution, by providing the side door assembly 10 and the top door assembly 20, the side door assembly 10 is provided on the peripheral side of the cutting chamber frame 300, which can form a relatively closed protective space around the cutting unit, and the cutting fluid will not splash out from the side of the cutting chamber. The top door assembly 20 is provided on the top of the cutting chamber frame 300, which can provide a protective function for the top of the cutting unit and prevent the cutting fluid from splashing out from the top of the cutting chamber. In addition, since the top door assembly 20 has an open state and a closed state, when the main roller of the cutting unit needs to be maintained or replaced, it is only necessary to open the top door assembly 20 to provide an operating window for replacing the main roller. The main roller can then be removed from the operating window formed by opening the top door assembly 20 for replacement, which facilitates the maintenance of the main roller in the cutting unit.

[0045] In some embodiments, please refer to Figure 2 The top door assembly 20 includes a top door frame 21 and a top panel door 22. The top door frame 21 is mounted on the top of the cutting chamber frame 300. One side of the top panel door 22 is pivotally connected to the top door frame 21, and the other side of the top panel door 22 is mounted on the top door frame 21. The top panel door 22 is provided with a handle 224. One side of the top panel door 22 is pivotally connected to the top door frame 21, and the other side is mounted on the top door frame 21. When the top panel door 22 needs to be opened, the operator applies pressure on the handle 224 to flip the top panel door 22 outward about one side of the hinge axis, switching the top panel door 22 from a closed state to an open state, exposing an operating window, and making operation convenient and quick.

[0046] Among them, the top door 22 can be directly placed on the top door frame 21 under the action of gravity, or it can be fixed on the top door frame 21 in other ways. For example, the top door 22 and the top door frame 21 can also be magnetically matched. A bar magnet is provided on the top door 22 frame, and the side of the top door 22 close to the magnet is made of metal. In this way, when the top door 22 is in a closed state, the magnet can provide a magnetic attraction to the top door 22, and the top door 22 is placed on the top door frame 21 more firmly. The top door 22 is not easily vibrated up and down due to the impact of the cutting fluid. When the top door 22 needs to be opened, it is only necessary to overcome the magnetic attraction between the top door 22 and the top door frame 21 bracket. Of course, a lock can also be provided between the top door 22 and the top door frame 21, which can also achieve a stable connection between the top door 22 and the top door frame 21.

[0047] In some embodiments, the top door 22 includes a first top door 221, a second top door 222, and a middle panel 223. The first top door 221 and the second top door 222 are spaced apart along the length of the top door frame 21. The middle panel 223 is disposed between the first top door 221 and the second top door 222. The first top door 221, the second top door 222, and the middle panel 223 enclose an operating window enclosed by the top door 22 frame. The middle panel 223 is detachably connected to the top door frame 21. By adopting a two-section split design for the top door 22, the top door 22 includes the first top door 221 and the second top door 222. This makes a single top door 22 lighter, and compared to opening the entire top door 22, opening the first top door 221 or the second top door 222 sequentially is more labor-saving. Furthermore, when it is necessary to observe the status of the main roller of the cutting unit, it is not necessary to completely open the entire top panel door 22. Only the first top panel door 221 or the second top panel door 222 needs to be opened, making the operation more convenient. By detachably connecting the middle panel 223 to the top door frame 21, the first top panel door 221, the second top panel door 222, and the middle panel 223 can be fully opened, exposing the operating window of the top door frame 21, which is convenient for maintenance and replacement of the main roller of the cutting unit.

[0048] Among them, the first top panel door 221 and the second top panel door 222 are respectively located on both sides of the middle panel 223. The middle panel 223 can block the gap between the first top panel door 221 and the second top panel door 222, ensuring the protection performance of the top panel door 22 against cutting fluid. There are many ways to connect the middle panel 223 and the top door frame 21. The middle panel 223 and the top door frame 21 can be screwed, snapped or magnetically connected. In this embodiment, the middle panel 223 and the top door frame 21 are screwed. The areas of the first top panel door 221 and the second top panel door 222 can be equal or unequal. In this embodiment, the areas of the first top panel door 221 and the second top panel door 222 are equal. Two handles 224 are respectively provided on the first top panel door 221 and the second top panel door 222.

[0049] In addition, a threading hole 211 is provided on the top door frame 21 , which is convenient for cutting and laying out indoor wiring, and a blocking piece may be provided at the threading hole 211 .

[0050] In some embodiments, there are two top door assemblies 20, each located above one side of the cutting unit's two main rollers. By providing two top door assemblies 20, the two top door assemblies 20 can be positioned corresponding to the left and right main rollers of the cutting unit, respectively. To replace the cutting unit's main rollers, simply open the corresponding top door assembly 20.

[0051] In some embodiments, the side door assembly 10 includes a winding chamber door 11, which is arranged on both sides of the cutting chamber frame 300 in a first direction. The winding chamber door 11 includes a first frame and a double-leaf door. The double-leaf door is installed in the winding area of ​​the cutting chamber frame 300 through the first frame. An observation window 111 is provided on the double-leaf door. The first direction is perpendicular to the vertical direction. By setting the winding chamber door 11, the winding chamber door 11 is installed in the winding area of ​​the cutting chamber frame 300, which can block the cutting fluid on the side of the cutting chamber in the first direction. The winding chamber door 11 adopts a double-leaf door design, which takes up less space when opening and closing, and is more convenient to open and close. The double-leaf door is provided with an observation window 111, which is convenient for staff to observe the wiring situation in the winding area through the observation window 111.

[0052] The observation window 111 may be a transparent glass window, and the first direction may be the length direction of the cutting chamber frame 300 .

[0053] In some embodiments, winding chamber door 11 further includes an inspection window 12. The first frame has a first end, which is away from the ground and has an opening. Inspection window 12 seals the opening and is spaced apart from an end surface of the first end. Inspection window 12 allows for easy maintenance of the winding area of ​​the cutting unit, facilitating replacement of winding and payoff rollers and other wiring.

[0054] The inspection window 12 is provided with a handle, and the operator can act on the handle to pull the inspection window 12 upwards to open the inspection window 12.

[0055] In some embodiments, the side door assembly 10 further includes a rolling shutter 13 and a water collection trough 14. The rolling shutters 13 are located on either side of the cutting chamber frame 300 in the second direction. The rolling shutters 13 prevent cutting fluid from splashing out of the front and back of the cutting chamber when the cutting unit is operating. The second direction, the first direction, and the vertical direction are perpendicular to each other. The water collection trough 14 is located below the shutters to collect cutting fluid that drips from the rolling shutters 13. The presence of the rolling shutters 13 shields the front and back of the cutting chamber, preventing cutting fluid from splashing out. When maintenance is required on the cutting chamber, the rolling shutters 13 can be opened to meet the needs. After maintenance is complete, the rolling shutters 13 can be closed, protecting both sides of the cutting chamber in the second direction from cutting fluid. Furthermore, the water collection trough 14 below the rolling shutters 13 collects cutting fluid that drips from the rolling shutters 13, preventing it from spilling and improving the working environment.

[0056] The rolling door 13 comprises a rolling door body, a rolling door shield, and rolling door guide slots. The rolling door guide slots are installed on both sides of the rolling door body and provide guidance for the raising and lowering of the rolling door body. The rolling door shield houses the reel, control box, rolling door mechanism, and limiter. A manual quick-release switch is installed on one side of the rolling door 13 to control the opening and closing of the rolling door body. The rolling door 13 is a conventional rolling door structure in the prior art and can be purchased directly, so the details of the rolling door 13 will not be elaborated here.

[0057] The second direction is a width direction of the cutting chamber frame 300 .

[0058] In some embodiments, the stone wire saw includes a base 200, which is used to support a cutting chamber frame 300; Figure 4As shown, the base 200 includes multiple columns 201 and connecting beams 202. The lower ends of the multiple columns 201 are connected to the foundation. The connecting beams 202 are used to connect the multiple columns 201 into a whole. The cutting chamber frame 300 is arranged at one end of the multiple columns away from the foundation. The protective device also includes an operating platform 30. The operating platform 30 is arranged around the bottom periphery of the cutting chamber frame 300 and is used to provide a workspace for the operator. The cutting chamber frame 300 is arranged on the top of the columns of the base 200, and the lower ends of the columns are connected to the base 200. That is, there is a height difference between the cutting chamber frame 300 and the foundation in the height direction. By providing the operating platform 30 on the bottom periphery of the cutting chamber frame 300, the operating platform 30 can provide the operator with a workspace for cutting chamber maintenance, making it easier for the operator to perform maintenance operations on the cutting chamber.
