Description

Technical Field

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

[0002] Wire cutting is a processing method in which the cutting wire reciprocates at high speed and moves relative to the workpiece to be cut (such as photovoltaic silicon rods, semiconductors, silicon carbide, sapphire, magnetic materials, etc.) to cut the workpiece.

[0003] A wire EDM machine consists of a cutting assembly and a retractable wire assembly. The cutting assembly defines a cutting zone within which a cutting unit is located. During the process of cutting the workpiece in the cutting zone, cutting fluid must be sprayed onto the workpiece. The cutting chamber is typically equipped with a retractable side door, which allows maintenance inside the cutting assembly. However, during the cutting process, the cutting fluid continuously impacts the side door, making it prone to leakage in the gap between the side door and the cutting frame of the cutting chamber. Utility Model Content

[0004] The embodiment of the present application provides a wire cutting machine that can effectively prevent cutting fluid from splashing out of the cutting chamber.

[0005] An embodiment of the present application provides a wire cutting machine, which includes a cutting assembly, a side door assembly and a first maze water baffle assembly. The cutting assembly includes a cutting frame and a cutting unit. The cutting unit is arranged in a cutting chamber enclosed by the cutting frame, and one side of the cutting frame has a first opening; the side door assembly includes a side door for closing the first opening, and the side door is installed on the cutting frame in a liftable manner along the vertical direction; the first maze water baffle assembly is extended along the vertical direction on the cutting frame, and the first maze water baffle assembly is located on the side of the side door facing the interior of the cutting chamber. A maze water baffle area is formed between the first maze water baffle assembly and the side door, and the first maze water baffle assembly is abutted against the inner wall of the side door to limit the conduction between the cutting fluid in the cutting chamber and the maze water baffle area.

[0006] In this embodiment, a side door is provided on one side of the first opening of the cutting frame to seal the first opening of the cutting frame. When the cutting unit is cutting the workpiece, cutting fluid continuously impacts the side door and the junction between the side door and the cutting frame. A first labyrinth water baffle assembly extending vertically is provided on the cutting frame, forming a labyrinth water retaining area between the first labyrinth water baffle assembly and the side door. Furthermore, the first labyrinth water baffle assembly abuts against the inner wall of the side door. When cutting fluid in the cutting chamber impacts the gap between the side door and the first labyrinth water baffle assembly, the first labyrinth water baffle assembly blocks most of the cutting fluid, allowing the cutting fluid to flow downward along the side door in the direction of gravity back into the cutting chamber. To ensure stable lifting and lowering of the side door, a certain gap exists between the first labyrinth water baffle assembly and the inner wall of the side door. A small amount of cutting fluid may enter the labyrinth water retaining area through the gap between the first labyrinth water baffle assembly and the inner wall of the side door. The cutting fluid entering the maze water retaining area will be blocked by the maze structure in the maze water retaining area. The maze structure can alleviate the impact force of the cutting fluid and effectively shorten the flow path of the cutting fluid in the maze water retaining area, so that the cutting fluid can fall quickly under the action of gravity and flow back to the cutting chamber, thereby better preventing the cutting fluid from splashing out of the cutting chamber, improving the protective effect of the side door on the cutting fluid, and reducing the probability of the cutting fluid overflowing outside the side door.

[0007] In some embodiments, both ends of the side door in a first direction have first folded edges bent toward the cutting chamber, the first direction is parallel to the length direction of the side door, and the first direction is perpendicular to the vertical direction.

[0008] In the above technical solution, a first folding edge is provided at both ends of the first direction of the side door. The first folding edge can block the cutting fluid entering the maze water retaining area, alleviate the impact force of the cutting fluid, allow the cutting fluid to fall quickly and flow back into the cutting chamber, and reduce the probability of the cutting fluid splashing out of the cutting chamber.

[0009] In some embodiments, the first maze water baffle assembly includes a first maze water baffle and a water baffle. The first maze water baffle is located on the side of the side door facing the interior of the cutting chamber and is arranged adjacent to the first folded edge. A maze water baffle area is formed between the first maze water baffle and the first folded edge. The water baffle is arranged on the first maze water baffle, and the water baffle is used to abut against the inner wall of the side door.

[0010] In the above technical solution, the first labyrinth water retaining plate assembly includes a first labyrinth water retaining plate and a water retaining member. A labyrinth water retaining area is formed between the first labyrinth water retaining plate and the first folding edge. The water retaining member is in contact with the inner wall of the side door. When the cutting fluid in the cutting chamber impacts the gap between the side door and the water retaining member, the water retaining member can block most of the cutting fluid, allowing the cutting fluid to flow down along the side door back to the cutting chamber, while a small amount of cutting fluid enters the labyrinth water retaining area from the gap between the water retaining member and the inner wall of the side door. The cutting fluid entering the labyrinth water retaining area will be blocked by the labyrinth structure formed by the first folding edge and the first labyrinth water retaining plate. The labyrinth structure can effectively alleviate the impact force of the cutting fluid, shorten the flow path of the cutting fluid in the labyrinth water retaining area, and allow the cutting fluid to quickly fall into the water receiving tray below under the action of gravity. The water receiving tray blocks and collects the cutting fluid, and finally flows back into the cutting chamber through the water receiving tray, thereby improving the protective effect of the side door on the cutting fluid and reducing the probability of the cutting fluid overflowing outside the side door.

[0011] In some embodiments, the first folding edge includes a first folding edge and a second folding edge, the first folding edge extends along the second direction, one end of the first folding edge is connected to the side door, and the other end is connected to the second folding edge, and the second folding edge extends along the first direction toward one side of the first maze water baffle; the second direction, the first direction and the vertical direction are perpendicular to each other; the first maze water baffle has a second folding edge bent toward one side of the first folding edge, along the first direction, the second folding edge and the second folding edge overlap, and along the second direction, there is a distance between the second folding edge and the second folding edge.

[0012] In the above technical solution, the first fold edge includes a first fold edge and a second fold edge, the first fold edge and the second fold edge are perpendicular to each other, and the corner of the first fold edge and the second fold edge forms a blocking area for the cutting fluid in the maze water retaining area. The first maze water retaining plate has a second fold edge bent toward one side of the first fold edge, and the second fold edge overlaps with the second fold edge and has a spacing in the second direction. In this way, the cutting fluid entering the maze water retaining area will be blocked by the second fold edge or the second fold edge, thereby effectively reducing the impact force of the cutting fluid after entering the maze water retaining area, shortening the path length of the cutting fluid in the maze water retaining area, and facilitating the cutting fluid to quickly fall into the water receiving tray below.

[0013] In some embodiments, the side door is vertically mounted on the cutting frame so as to be liftable, and a scraper for sealingly cooperating with the first labyrinth water baffle is provided on the inner side of the side door.

[0014] In the above technical solution, a scraper is provided on the inner side of the side door for sealing with the first labyrinth water baffle. The scraper can make the sealing between the first labyrinth water baffle and the side door better, and the cutting fluid is not easy to flow out of the cutting chamber. In the process of raising and lowering the side door, the scraper can effectively guide the cutting fluid flowing from the side door to the scraper toward the inner side of the cutting chamber, and the cutting fluid will not directly fall down from the gap between the first labyrinth water baffle and the side door.

[0015] In some embodiments, the scraper includes a scraper body and a first rubber strip, the scraper body has a first side facing the first labyrinth water baffle, the first rubber strip is installed on the first side to seal with the first labyrinth water baffle; the scraper body has a second side facing the side door, the second side is provided with a second rubber strip, and the scraper body is sealed with the side door through the second rubber strip.

[0016] In the above technical solution, the first rubber strip and the second rubber strip are arranged on the scraper body, and the first rubber strip and the second rubber strip have a certain deformation ability. The scraper is in sealing contact with the first labyrinth water baffle through the first rubber strip, and is sealed with the inner wall of the side door through the second rubber strip, so that the sealing of the joint surface between the scraper and the first labyrinth water baffle and the side door is better. During the process of raising and lowering the side door, the cutting fluid is not easy to fall from the gap between the scraper and the first labyrinth water baffle and the side door to the cutting line area below.

[0017] In some embodiments, the scraper body has a third side away from the first labyrinth water retaining plate, and the scraper body is tilted downward in a direction from the first side to the third side.

[0018] In the above technical solution, by tilting the scraper body downward, the cutting fluid on the scraper body can flow back to the cutting chamber toward the third side of the scraper body under the action of the slope, and it is difficult for cutting fluid to remain in the scraper.

[0019] In some embodiments, the scraper also includes a scraper mounting member, which is installed on the side door. The scraper mounting member has an elongated hole extending along the second direction. The scraper body is passed through the elongated hole by a fastener to connect the scraper body to the scraper mounting member.

[0020] In the above technical solution, the scraper body is installed on the side door through the scraper mounting piece, and a corresponding elongated hole extending along the second direction is provided on the scraper mounting piece. In this way, when installing the scraper body, the position of the scraper body can be fine-tuned along the length direction of the elongated hole. The elongated hole has an adjustment margin for the installation of the scraper body, which reduces the difficulty of installing the scraper body and helps to ensure the sealing fit between the scraper and the side door.

[0021] In some embodiments, the side door assembly also includes a lifting mechanism, which is arranged on the cutting frame, and the lifting mechanism is used to drive the side door to move in the vertical direction; a second maze water baffle is provided on the side of the cutting frame close to the first maze water baffle, and the second maze water baffle extends in the vertical direction. The second maze water baffle is surrounded by the side of the lifting mechanism facing the first maze water baffle, and the side of the second maze water baffle away from the side door is abutted against the side of the first maze water baffle away from the side door, so that the maze water baffle area forms a closed chamber.

[0022] In the above technical solution, since the lifting mechanism is the driving mechanism for driving the side door to lift, in order to reduce the probability of cutting fluid entering the lifting mechanism and ensure the stable and normal operation of the lifting mechanism, a second labyrinth water baffle is provided on one side of the first labyrinth water baffle. The second labyrinth water baffle is arranged on the side of the lifting mechanism facing the first labyrinth water baffle, and the side of the second labyrinth water baffle away from the side door abuts against the side of the first labyrinth water baffle away from the side door, so that the labyrinth water baffle area forms a chamber that is closed on all sides. In this way, even if a portion of the cutting fluid enters the labyrinth water baffle area, since the labyrinth water baffle area is a chamber that is closed on all sides, the cutting fluid will not enter the interior of the lifting mechanism, but will only fall into the water receiving tray below the labyrinth water baffle area along the direction of gravity, thereby ensuring that the cutting fluid will not enter the lifting mechanism and ensuring the normal operation of the lifting mechanism. Moreover, even when the side door is in an open state, when flushing water is manually sprayed from the outside into the labyrinth water baffle area, the labyrinth water baffle area forms a chamber that is closed on all sides, and flushing water is not easy to enter the interior of the lifting mechanism.

[0023] In some embodiments, the wire cutting machine also includes a water receiving tray, which is arranged on one side of the bottom of the cutting frame, and the water receiving tray is used to receive the cutting fluid entering the maze water retaining area; the water receiving tray is formed with a first flange on both sides of the first direction, and along the second direction, the water receiving tray is formed with a second flange on the side close to the side door, and the other side of the water receiving tray extends into the cutting chamber and is open, the first direction is parallel to the length direction of the side door, and the second direction, the first direction and the vertical direction are perpendicular to each other.

[0024] In the above technical solution, a water collecting pan is provided at the bottom of the cutting frame, which can collect cutting fluid that enters the maze water retaining area and allow the cutting fluid to flow back into the cutting chamber. A first flange is formed on both sides of the water collecting pan in a first direction, a second flange is formed on the side of the water collecting pan close to the side door, and the other side of the water collecting pan extends into the cutting chamber and is open. The first flange and the second flange can effectively block and guide the cutting fluid that falls into the water collecting pan, allowing the cutting fluid in the water collecting pan to flow toward the open side of the water collecting pan away from the side door and back into the cutting chamber, thereby preventing the cutting fluid from being retained in the water collecting pan. In some embodiments, the side door assembly also includes a water retaining portion, which is arranged on the inner side of the side door and located on the upper side of the water receiving tray; the water retaining portion includes a baffle and a drainage member, the baffle is connected to the side door, the baffle covers the water receiving tray, and is used to receive the cutting fluid blocked by the side door and drain the cutting fluid toward the cutting chamber; the drainage member extends along the first direction and is arranged at the bottom of the baffle, and the drainage member is used to abut against the water receiving tray when the side door is closed, so as to drain the cutting fluid in the water receiving tray to both sides of the first direction of the water receiving tray.

[0025] In the above technical solution, a water retaining portion is provided on the inner side of the side door, and a baffle in the water retaining portion is located on one side above the water receiving tray. The baffle can receive the cutting liquid blocked by the side door and drain the cutting liquid toward the cutting chamber, thereby preventing a large amount of cutting liquid from falling into the water receiving tray, reducing the risk of overflow of the water receiving tray, and also preventing the cutting liquid from dripping along the wall of the side door onto the cutting line of the cutting unit below, causing the cutting line to be wet. In addition, since the cutting line is arranged in the middle area of ​​the side of the water receiving tray away from the side door, the drainage member below the baffle can guide the cutting liquid in the water receiving tray when the side door is in the closed state, draining the cutting liquid in the water receiving tray to both sides of the first direction of the water receiving tray, so that the cutting liquid in the water receiving tray will not flow out from the middle area of ​​the water receiving tray, thereby preventing the cutting liquid in the water receiving tray from dripping onto the cutting line.

[0026] In some embodiments, along the second direction, the baffle includes a connecting plate and a guide plate, the connecting plate extending in the vertical direction, the baffle being connected to the side door via the connecting plate, the guide plate being perpendicularly connected to the connecting plate and extending toward a side away from the side door, the guide plate being configured to receive cutting fluid blocked by the side door and direct the cutting fluid toward the cutting chamber, and the guide plate having water-retaining flanges formed on both sides of the first direction. The first direction, the second direction, and the vertical direction are all perpendicular to each other.

[0027] In the above technical solution, the baffle is fixed to the side plate via a connecting plate. The connecting plate increases the connection area between the baffle and the side door, thereby enhancing the installation stability of the baffle. The guide plate extends toward the side away from the side door, thereby receiving the cutting fluid blocked by the side door and directing the cutting fluid toward the cutting chamber, allowing the cutting fluid to flow back into the cutting chamber and prevent it from dripping onto the cutting line of the cutting unit below. By forming water-retaining flanges on both sides of the guide plate in the first direction, the water-retaining flanges can block the cutting fluid on the guide plate, preventing the cutting fluid from overflowing from both sides of the baffle in the first direction.

[0028] In some embodiments, along the second direction, the guide plate includes a first guide plate and a second guide plate, one end of the first guide plate is connected to the connecting plate, and the other end is connected to the second guide plate, and the second guide plate is telescopically arranged on the first guide plate to adjust the length of the guide plate in the second direction, and the second direction is perpendicular to the vertical direction.

[0029] In the above technical solution, by dividing the guide plate into a first guide plate and a second guide plate, the second guide plate cooperates with the first guide plate, so that the extension length of the guide plate can be adjusted, and then the coverage range of the baffle can be adjusted, which has a wider range of applicability and can meet the water-blocking needs of the baffle.

[0030] In some embodiments, the first guide plate and / or the second guide plate are arranged to be tilted downward in a direction from the first guide plate to the second guide plate.

[0031] In the above technical solution, by tilting the first guide plate and / or the second guide plate downward, the first guide plate and / or the second guide plate have a downward slope, which is more conducive to the cutting fluid flowing toward the cutting chamber along the slope of the guide plate under the action of gravity.

[0032] In some embodiments, a plurality of stiffening ribs are protruding from the first guide plate, and the plurality of stiffening ribs are distributed on the first guide plate at intervals along the first direction. A guide channel is formed between two adjacent stiffening ribs for the cutting fluid to flow into the second guide plate, and the first direction, the second direction and the vertical direction are perpendicular to each other.

[0033] In the above technical solution, the protruding stiffening ribs on the first guide plate enhance the structural strength of the first guide plate, making it more robust and more resilient to the impact of the cutting fluid. Furthermore, a guide channel is formed between two adjacent stiffening ribs, allowing the cutting fluid to flow into the second guide plate. This channel guides the cutting fluid from the first guide plate, ensuring a more even flow from the first to the second guide plate.

[0034] In some embodiments, the top of the side door is provided with a third folded edge folded toward the inside of the cutting chamber, and a sealing gasket is provided at the bottom of the third folded edge; the top of the cutting frame is correspondingly provided with a top plate, and a third maze water baffle is provided on the top plate, and the third maze water baffle has a third folded edge folded upward on the side close to the third folded edge; when the side door is in a closed state, the third folded edge is sealed with the third maze water baffle through the sealing gasket.

[0035] In the above technical solution, a third folded edge folded toward the cutting chamber is provided on the top of the side door, and a third maze water baffle is correspondingly provided on the top plate of the cutting frame. The third folded edge and the third folded edge of the third maze water baffle form a maze water baffle structure. When the side door is in a closed state, the third folded edge is sealed with the third maze water baffle through a sealing gasket, and the sealing gasket acts as a partition, so that the maze water baffle structure is a closed cavity, ensuring that the cutting fluid does not splash out from the top of the cutting frame.

[0051] Example

[0052] This application embodiment provides a wire cutting machine, please refer to Figures 1 to 7 The wire cutting machine 100 includes a cutting assembly, a side door assembly 20 and a first labyrinth water baffle assembly 30. The cutting assembly includes a cutting frame 10 and a cutting unit. The cutting unit is arranged in a cutting chamber enclosed by the cutting frame 10, and one side of the cutting frame 10 has a first opening 11; the side door assembly 20 includes a side door 21 for closing the first opening 11, and the side door 21 is installed on the cutting frame 10 in a liftable manner along the vertical direction Z; the first labyrinth water baffle assembly 30 is extended along the vertical direction Z on the cutting frame 10, and the first labyrinth water baffle assembly 30 is located on the side of the side door 21 facing the interior of the cutting chamber. A labyrinth water baffle area 35 is formed between the first labyrinth water baffle assembly 30 and the side door 21, and the first labyrinth water baffle assembly 30 is abutted against the inner wall of the side door 21 to limit the conduction between the cutting fluid in the cutting chamber and the labyrinth water baffle area 35.

[0053] In this solution, the side door 21 is provided on one side of the first opening 11 of the cutting frame 10 to seal the first opening 11 of the cutting frame 10. When the cutting unit is cutting the workpiece, the cutting fluid will continuously impact the side door 21 and the junction between the side door 21 and the cutting frame 10. By providing a first labyrinth water baffle assembly 30 extending along the vertical direction Z on the cutting frame 10, a labyrinth water retaining area 35 is formed between the first labyrinth water baffle assembly 30 and the side door 21, and the first labyrinth water baffle assembly 30 is in contact with the inner wall of the side door 21. When the cutting fluid in the cutting chamber impacts the gap between the side door 21 and the first labyrinth water baffle assembly 30, the first labyrinth water baffle assembly 30 can block most of the cutting fluid, allowing the cutting fluid to flow downward along the side door 21 and back to the cutting chamber in the direction of gravity. In order to ensure that the side door 21 can be raised and lowered stably, there will be a certain gap between the first labyrinth water retaining plate assembly 30 and the inner wall of the side door 21. A small amount of cutting fluid will still enter the labyrinth water retaining area 35 from the gap between the first labyrinth water retaining plate assembly 30 and the inner wall of the side door 21. The cutting fluid entering the labyrinth water retaining area 35 will be blocked by the labyrinth structure within the labyrinth water retaining area 35. The labyrinth structure can alleviate the impact force of the cutting fluid and effectively shorten the flow path of the cutting fluid in the labyrinth water retaining area 35, allowing the cutting fluid to fall quickly under the action of gravity and flow back into the cutting chamber, thereby better preventing the cutting fluid from splashing out of the cutting chamber, improving the protective effect of the side door 21 on the cutting fluid, and reducing the probability of the cutting fluid overflowing outside the side door 21.

[0054] The cutting frame 10 is the main frame structure of the cutting assembly. The cutting frame 10 is a rectangular frame structure. The cutting frame 10 serves as the main structure, supports the cutting unit and is installed for the cutting unit. The first opening 11 is an opening on one side of the cutting frame 10. The side door 21 is installed at the first opening 11 of the cutting frame 10 to close the first opening 11.

[0055] The side door 21 can be formed by welding together multiple pieces of sheet metal. Alternatively, the side door 21 can be made from a single piece of sheet metal. A handle 212 is provided on the side door 21. The side door 21 is mounted on the cutting frame 10 in a vertical direction Z, meaning that the side door 21 is capable of vertical movement relative to the cutting frame 10 in the vertical direction Z. Below the side door 21 on the cutting frame 10 is the winding chamber door 12.

[0056] In some embodiments, please refer to Figure 4 and Figure 5The side door 21 has first folded edges 211 at both ends in a first direction X, which are bent toward the cutting chamber. The first direction X is parallel to the length of the side door 21 and perpendicular to the vertical direction Z. The first folded edges 211 are provided at both ends of the side door 21 in the first direction X. The first folded edges 211 can block cutting fluid entering the labyrinth water retaining area 35, mitigate the impact of the cutting fluid, allow the cutting fluid to quickly fall back into the cutting chamber, and reduce the probability of the cutting fluid splashing out of the cutting chamber.

[0057] In some embodiments, the first labyrinth water baffle assembly 30 includes a first labyrinth water baffle 31 and a water baffle 32. The first labyrinth water baffle 31 is located on the side of the side door 21 facing the interior of the cutting chamber and is arranged adjacent to the first folded edge 211. A labyrinth water baffle area 35 is formed between the first labyrinth water baffle 31 and the first folded edge 211; the water baffle 32 is arranged on the first labyrinth water baffle 31, and the water baffle 32 is used to abut against the inner wall of the side door 21.

[0058] The first labyrinth water baffle assembly 30 includes a first labyrinth water baffle 31 and a water baffle 32. A labyrinth water baffle area 35 is formed between the first labyrinth water baffle 31 and the first folded edge 211. The water baffle 32 is abutted against the inner wall of the side door 21. When the cutting fluid in the cutting chamber impacts the gap between the side door 21 and the water baffle 32, the water baffle 32 can block most of the cutting fluid, allowing the cutting fluid to flow down along the side door 21 back to the cutting chamber, while a small amount of cutting fluid enters the labyrinth water baffle area 35 from the gap between the water baffle 32 and the inner wall of the side door 21. The cutting fluid entering the maze water retaining area 35 will be blocked by the maze structure formed by the first folded edge 211 and the first maze water retaining plate 31. The maze structure can effectively alleviate the impact force of the cutting fluid, shorten the flow path of the cutting fluid in the maze water retaining area 35, and allow the cutting fluid to quickly fall into the water receiving tray 40 below under the action of gravity. The water receiving tray 40 blocks and collects the cutting fluid, and finally flows back into the cutting chamber through the water receiving tray 40, thereby improving the protective effect of the side door 21 on the cutting fluid and reducing the probability of the cutting fluid overflowing out of the side door 21.

[0059] The first labyrinth water retaining plate 31 refers to a labyrinth water retaining plate structure composed of multiple retaining plates vertically connected to each other in sequence. The corner between each two retaining plates can block the cutting fluid entering the labyrinth water retaining area 35, thereby alleviating the impact force of the cutting fluid and changing the path of the cutting fluid.

[0060] The first labyrinth water baffle 31 is mounted on the cutting frame 10. Specifically, the bottom of the first labyrinth water baffle 31 is connected to the bottom of the cutting frame 10, and the top side of the first labyrinth water baffle 31 is connected to the top side of the cutting frame 10. The first labyrinth water baffle 31 is extended along the vertical direction Z as a whole, and the height of the first labyrinth water baffle 31 can be the same as the height of the side door 21.

[0061] The water retaining member 32 is a water retaining component provided on the first labyrinth water retaining plate 31 . The first labyrinth water retaining plate assembly 30 abuts against the inner wall of the side door 21 through the water retaining member 32 , thereby blocking the cutting fluid in the cutting chamber.

[0062] The inner wall of the side door 21 refers to the inner wall of the side door 21 close to the cutting chamber, that is, the side wall of the side door 21 located in the cutting chamber.

[0063] The water retaining member 32 is detachably connected to the first labyrinth water retaining plate 31. Since the water retaining member 32 is constantly subjected to the impact of the cutting fluid and is a vulnerable part, the detachable connection between the water retaining member 32 and the first labyrinth water retaining plate 31 facilitates the replacement of the water retaining member 32 and ensures the water retaining effect of the water retaining member 32 on the cutting fluid.

[0064] The water retaining member 32 can be connected to the first labyrinth water retaining plate 31 in a variety of ways. For example, the water retaining member 32 can be connected to the first labyrinth water retaining plate 31 through a threaded connection, a snap connection, or a pin connection. For example, the water retaining member 32 is fixed to the first labyrinth water retaining plate 31 via bolts. To replace the water retaining member 32, simply remove the bolts and replace it with a new one.

[0065] The water retaining member 32 can be a plate structure, and the water retaining member 32 extends along the vertical direction Z and is arranged on the first labyrinth water retaining plate 31. It includes a body and a bevel, and the water retaining member 32 is installed on the first labyrinth water retaining plate 31 through the body, and the bevel is bent toward the first folding edge 211.

[0066] In some embodiments, please refer to Figure 4 and Figure 5The first folding edge 211 includes a first folding edge 2111 and a second folding edge 2112. The first folding edge 2111 extends along the second direction Y, one end of the first folding edge 2111 is connected to the side door 21, and the other end is connected to the second folding edge 2112. The second folding edge 2112 extends along the first direction X toward one side of the first maze water baffle 31; the second direction Y, the first direction X and the vertical direction Z are perpendicular to each other; the first maze water baffle 31 has a second folding edge 33 bent toward one side of the first folding edge 211, along the first direction X, the second folding edge 33 overlaps with the second folding edge 2112, and along the second direction Y, there is a distance between the second folding edge 33 and the second folding edge 2112. The first folded edge 211 includes a first folded edge 2111 and a second folded edge 2112, and the first folded edge 2111 and the second folded edge 2112 are perpendicular to each other. The corner of the first folded edge 2111 and the second folded edge 2112 forms a blocking area for the cutting fluid in the maze water retaining area 35. The first maze water retaining plate 31 has a second folded edge 33 bent toward the side of the first folded edge 211. The second folded edge 33 overlaps with the second folded edge 2112 and has a spacing in the second direction Y. In this way, the cutting fluid entering the maze water retaining area 35 will be blocked by the second folded edge 33 or the second folded edge 2112, thereby effectively reducing the impact force of the cutting fluid after entering the maze water retaining area 35, shortening the path length of the cutting fluid in the maze water retaining area 35, and facilitating the cutting fluid to quickly fall into the water receiving tray 40 below.

[0067] In some embodiments, a scraper 22 for sealingly cooperating with the first labyrinth water baffle 31 is provided on the inner side of the side door 21. By providing the scraper 22 for sealingly cooperating with the first labyrinth water baffle 31 on the inner side of the side door 21, the scraper 22 can improve the sealing between the first labyrinth water baffle 31 and the side door 21, and the cutting fluid is not easy to flow out of the cutting chamber. Moreover, during the process of raising and lowering the side door 21, the scraper 22 can effectively guide the cutting fluid flowing from the side door 21 onto the scraper 22 toward the inner side of the cutting chamber, and the cutting fluid will not directly spill downward from the gap between the first labyrinth water baffle 31 and the side door 21.

[0068] The inner side of the side door 21 refers to the side of the side door 21 located in the cutting chamber, that is, the side wall of the side door 21 in contact with the cutting fluid.

[0069] In some embodiments, the scraper 22 includes a scraper body 221 and a first rubber strip 222. The scraper body 221 has a first side facing the first labyrinth water baffle 31, and the first rubber strip 222 is installed on the first side to seal with the first labyrinth water baffle 31; the scraper body 221 has a second side facing the side door 21, and the second side is provided with a second rubber strip 223. The scraper body 221 is sealed with the side door 21 through the second rubber strip 223. The first rubber strip 222 and the second rubber strip 223 are arranged on the scraper body 221, and the first rubber strip 222 and the second rubber strip 223 have a certain deformation ability. The scraper 22 is in sealed contact with the first labyrinth water baffle 31 through the first rubber strip 222, and is sealed with the inner wall of the side door 21 through the second rubber strip 223, so that the sealing of the joint surface between the scraper 22 and the first labyrinth water baffle 31 and the side door 21 is better. During the lifting and lowering process of the side door 21, the cutting fluid is not easy to fall from the gap between the scraper 22 and the first labyrinth water baffle 31 and the side door 21 to the cutting line area below.

[0070] The first rubber strip 222 and the second rubber strip 223 are side rubber strips. The first rubber strip 222 and the second rubber strip 223 can be fixed to the scraper body 221 by means of adhesive.

[0071] In some embodiments, the scraper body 221 has a third side away from the first labyrinth water retaining plate 31. The scraper body 221 is tilted downward from the first side to the third side. By tilting the scraper body 221 downward, the cutting fluid on the scraper body 221 can flow back into the cutting chamber toward the third side of the scraper body 221 due to the effect of the slope, and it is less likely that the cutting fluid will remain on the scraper 22.

[0072] In some embodiments, the scraper 22 further includes a scraper 22 mounting member, which is mounted on the side door 21. The scraper 22 mounting member has an elongated hole extending along the second direction Y. The scraper body 221 is inserted through the elongated hole via a fastener to connect the scraper body 221 to the scraper 22 mounting member. The scraper body 221 is mounted on the side door 21 via the scraper 22 mounting member. The scraper 22 mounting member has a corresponding elongated hole extending along the second direction Y. In this way, when the scraper body 221 is installed, the position of the scraper body 221 can be fine-tuned along the length of the elongated hole. The elongated hole provides an adjustment margin for the scraper body 221 during installation, reducing the difficulty of installing the scraper body 221 and facilitating a sealed fit between the scraper 22 and the side door 21.

[0073] The fastener can be a bolt. The scraper body 221 is provided with a connection hole through which the fastener is inserted. When adjusting the position of the scraper body 221, the fastener can be moved along the length of the elongated hole. Once in position, i.e., when the scraper body 221 is sealed against the side door 21, the fastener's nut can be tightened. The number of fasteners can be one or more. In this embodiment, there are two fasteners, which stably secure the scraper body 221 to the scraper 22 mounting member.

[0074] In some embodiments, the side door assembly 20 also includes a lifting mechanism 24, which is arranged on the cutting frame 10, and the lifting mechanism 24 is used to drive the side door 21 to move along the vertical direction Z; the cutting frame 10 is provided with a second maze water baffle 34 on the side close to the first maze water baffle 31, and the second maze water baffle 34 extends along the vertical direction Z. The second maze water baffle 34 is surrounded by the side of the lifting mechanism 24 facing the first maze water baffle 31, and the side of the second maze water baffle 34 away from the side door 21 is abutted against the side of the first maze water baffle 31 away from the side door 21, so that the maze water baffle area 35 forms a closed chamber.

[0075] Since the lifting mechanism 24 is a driving mechanism for driving the side door 21 to rise and fall, in order to reduce the probability of cutting fluid entering the lifting mechanism 24 and ensure the stable and normal operation of the lifting mechanism 24, a second labyrinth water baffle 34 is provided on one side of the first labyrinth water baffle 31. The second labyrinth water baffle 34 is arranged on the side of the lifting mechanism 24 facing the first labyrinth water baffle 31, and the side of the second labyrinth water baffle 34 away from the side door 21 abuts against the side of the first labyrinth water baffle 31 away from the side door 21, so that the labyrinth water baffle area 35 forms a chamber closed on all sides. In this way, even if a part of the cutting fluid enters the labyrinth water baffle area 35, since the labyrinth water baffle area 35 is a chamber closed on all sides, the cutting fluid will not enter the interior of the lifting mechanism 24, but can only fall into the water receiving tray 40 below the labyrinth water baffle area 35 along the direction of gravity, thereby ensuring that the cutting fluid does not enter the lifting mechanism 24 and ensuring the normal operation of the lifting mechanism 24. Even when the side door 21 is in the open state, when flushing water is sprayed from the outside to the labyrinth water retaining area 35 , the labyrinth water retaining area 35 forms a chamber closed on all sides, and the flushing water is not easy to enter the interior of the lifting mechanism 24 .

[0076] Among them, the lifting mechanism 24 refers to a lifting component that provides lifting function to the side door 21. The lifting mechanism 24 can be a linear drive mechanism such as a screw-nut pair mechanism, a gear rack, a cylinder or a hydraulic cylinder. The specific lifting mechanism 24 can be determined according to actual conditions. It is an existing technology and will not be repeated here.

[0077] In some embodiments, the wire cutting machine 100 further includes a water collecting pan 40, which is disposed at one side of the bottom of the cutting frame 10. The water collecting pan 40 is used to receive cutting fluid that enters the maze water retaining area 35. The water collecting pan 40 has first flanges formed on both sides in the first direction X. In the second direction Y, the water collecting pan 40 has a second flange formed on the side proximal to the side door 21. The other side of the water collecting pan 40 extends into the cutting chamber and is open. By disposing the water collecting pan 40 at the bottom of the cutting frame 10, the water collecting pan 40 can collect the cutting fluid that enters the maze water retaining area 35, allowing the cutting fluid to flow back into the cutting chamber. By forming a first flange on both sides of the first direction X of the water receiving tray 40, a second flange is formed on the side of the water receiving tray 40 close to the side door 21, and the other side of the water receiving tray 40 extends into the cutting chamber and is open. The first flange and the second flange can effectively block and guide the cutting liquid falling into the water receiving tray 40, allowing the cutting liquid in the water receiving tray 40 to flow toward the open side of the water receiving tray 40 away from the side door 21, and flow back into the cutting chamber, thereby avoiding the cutting liquid from being retained in the water receiving tray 40.

[0078] The first flange and / or the second flange are flange structures extending upward along the vertical direction Z on the water receiving tray 40. The other side of the water receiving tray 40 being open means that the side of the water receiving tray 40 away from the side door 21 is not provided with a flange structure, and water in the water receiving tray 40 can directly flow into the cutting chamber from the open side of the water receiving tray 40.

[0079] The water receiving tray 40 is arranged to be tilted downward toward the cutting chamber from a side close to the side door 21, that is, the surface of the water receiving tray 40 has a slope, which is conducive to guiding the cutting liquid falling into the water receiving tray 40 toward the cutting chamber, thereby avoiding the cutting liquid from being retained in the water receiving tray 40.

[0080] In addition, the water receiving tray 40 is tilted downward from the direction of the second flange to the open side, so that the water in the water receiving tray 40 can gradually flow to the side of the water receiving tray 40 away from the side door 21 under the action of gravity, which is beneficial for the cutting liquid in the water receiving tray 40 to flow back to the cutting chamber.

[0081] In some embodiments, please combine Figure 3 and Figure 6 The side door assembly 20 also includes a water retaining portion 25, which is arranged on the inner side of the side door 21 and located on the upper side of the water receiving tray 40; the water retaining portion 25 includes a baffle 251 and a guide member 252, the baffle 251 is connected to the side door 21, the baffle 251 covers the water receiving tray 40, and is used to receive the cutting fluid blocked by the side door 21 and guide the cutting fluid toward the cutting chamber; the guide member 252 extends along the first direction X and is arranged at the bottom of the baffle 251, and the guide member 252 is used to abut against the water receiving tray 40 when the side door 21 is closed, so as to guide the cutting fluid in the water receiving tray 40 to both sides of the first direction X of the water receiving tray 40.

[0082] A water retaining portion 25 is provided on the inner side of the side door 21. The baffle 251 in the water retaining portion 25 is located on the upper side of the water receiving tray 40. The baffle 251 can receive the cutting liquid blocked by the side door 21 and drain the cutting liquid toward the cutting chamber, which can prevent a large amount of cutting liquid from falling into the water receiving tray 40, reduce the risk of overflow of the water receiving tray 40, and prevent the cutting liquid from dripping along the wall of the side door 21 onto the cutting line of the cutting unit below, causing the cutting line to be water-carrying. In addition, since a cutting line is arranged in the middle area of ​​the side of the water receiving tray 40 away from the side door 21, the guide member 252 is set below the baffle 251. When the side door 21 is in a closed state, the guide member 252 can guide the cutting liquid in the water receiving tray 40, and guide the cutting liquid in the water receiving tray 40 to both sides of the first direction X of the water receiving tray 40, so that the cutting liquid in the water receiving tray 40 will not flow out from the middle area of ​​the water receiving tray 40, thereby preventing the cutting liquid in the water receiving tray 40 from dripping onto the cutting line.

[0083] The guide member 252 can be a strip of rubber sealing strip. The guide member 252 extends along the first direction X and is arranged at the bottom of the baffle 251. The guide member 252 is arranged near the side of the water receiving tray 40 away from the side door 21. The guide member 252 can prevent the cutting liquid in the labyrinth water retaining area 35 from dripping onto the water receiving tray 40 instead of flowing out of the middle area of ​​the water receiving tray 40 into the cutting chamber, thereby preventing the cutting liquid in the water receiving tray 40 from dripping onto the cutting line.

[0084] In some embodiments, please refer to Figure 6 Along the second direction Y, the baffle 251 includes a connecting plate 2511 and a guide plate 2512. The connecting plate 2511 extends along the vertical direction Z. The baffle 251 is connected to the side door 21 via the connecting plate 2511. The guide plate 2512 is perpendicularly connected to the connecting plate 2511 and extends toward the side away from the side door 21. The guide plate 2512 is used to receive the cutting fluid blocked by the side door 21 and guide the cutting fluid toward the cutting chamber. The guide plate 2512 has water-retaining flanges formed on both sides of the first direction X. The first direction X, the second direction Y, and the vertical direction Z are perpendicular to each other. The baffle 251 is fixed to the side plate via the connecting plate 2511. The connecting plate 2511 increases the connection area between the baffle 251 and the side door 21, and the installation stability of the baffle 251 is higher. The guide plate 2512 extends toward the side away from the side door 21, thereby receiving the cutting fluid blocked by the side door 21 and directing it toward the cutting chamber, allowing it to flow back into the cutting chamber and preventing it from dripping onto the cutting line of the cutting unit below. The guide plate 2512 has water-retaining flanges formed on both sides of the first direction X. These flanges can block the cutting fluid on the guide plate 2512, preventing it from overflowing from both sides of the baffle 251 in the first direction X.

[0085] In some embodiments, please refer to Figure 6 Along the second direction Y, the guide plate 2512 includes a first guide plate 2512a and a second guide plate 2512b. One end of the first guide plate 2512a is connected to the connecting plate 2511, and the other end is connected to the second guide plate 2512b. The second guide plate 2512b is retractably disposed on the first guide plate 2512a to adjust the length of the guide plate 2512 in the second direction Y, which is perpendicular to the vertical direction Z. By dividing the guide plate 2512 into the first guide plate 2512a and the second guide plate 2512b, and cooperating with the first guide plate 2512a, the extension length of the guide plate 2512 is adjustable, thereby adjusting the coverage range of the baffle 251, thereby expanding the scope of application and meeting the water blocking requirements of the baffle 251.

[0086] The first deflector plate 2512a has an elongated mounting hole along the second direction Y. The second deflector plate 2512b has a corresponding connecting hole. Bolts are passed through the connecting holes to securely attach to the mounting holes on the first deflector plate 2512a. To adjust the length of the deflector plate 2512, simply loosen the fasteners and move the second deflector plate 2512b relative to the first deflector plate 2512a in the second direction Y. Once the length of the deflector plate 2512 is adjusted, tighten the bolts again.

[0087] In some embodiments, the first guide plate 2512a and / or the second guide plate 2512b are arranged to be tilted downward, from the direction of the first guide plate 2512a to the direction of the second guide plate 2512b. By tilting the first guide plate 2512a and / or the second guide plate 2512b downward, the first guide plate 2512a and / or the second guide plate 2512b have a downward slope, which is more conducive to the cutting fluid flowing toward the cutting chamber under the action of gravity along the slope of the guide plate 2512.

[0088] The first guide plate 2512a and the second guide plate 2512b are both arranged to be inclined downward, and the inclination of the second guide plate 2512b is greater than the inclination of the first guide plate 2512a.

[0089] In some embodiments, a plurality of stiffening ribs 2513 are protruding from the first guide plate 2512a, and the plurality of stiffening ribs 2513 are spaced apart on the first guide plate 2512a along the first direction X. A guide channel is formed between two adjacent stiffening ribs 2513 for the cutting fluid to flow into the second guide plate 2512b, and the first direction X, the second direction Y and the vertical direction Z are perpendicular to each other.

[0090] The protruding stiffening ribs 2513 on the first guide plate 2512a enhance the structural strength of the first guide plate 2512a, making it more robust and more resilient to the impact of the cutting fluid. Furthermore, a guide channel is formed between two adjacent stiffening ribs 2513, allowing the cutting fluid to flow into the second guide plate 2512b. This channel guides the cutting fluid from the first guide plate 2512a, allowing it to flow more evenly from the first guide plate 2512a to the second guide plate 2512b.

[0091] The stiffening ribs 2513 are extended along the second direction Y and are disposed on the first guide plate 2512 a . The stiffening ribs 2513 are welded and fixed to the first guide plate 2512 a .

[0092] In some embodiments, please refer to Figure 7 The top of the side door 21 is provided with a third folded edge 213 folded toward the inside of the cutting chamber, and a sealing gasket 214 is provided at the bottom of the third folded edge 213; the top of the cutting frame 10 is correspondingly provided with a top plate 50, and a third maze water baffle 51 is provided on the top plate 50, and the third maze water baffle 51 has a third folded edge 511 folded upward on the side close to the third folded edge 213; when the side door 21 is in a closed state, the third folded edge 213 is sealed with the third maze water baffle 51 through the sealing gasket 214. By providing a third folded edge 213 folded toward the cutting chamber on the top of the side door 21, a third labyrinth water baffle 51 is correspondingly provided on the top plate 50 of the cutting frame 10. The third folded edge 213 and the third folded edge 511 of the third labyrinth water baffle 51 form a labyrinth water retaining structure. When the side door 21 is in a closed state, the third folded edge 213 is sealed with the third labyrinth water baffle 51 through the sealing gasket 214. The sealing gasket 214 acts as a partition, so that the labyrinth water retaining structure is a closed cavity, ensuring that the cutting fluid does not splash out from the top of the cutting frame 10.

[0093] The sealing gasket 214 may be a side foam silicone sealing strip, and the sealing gasket 214 extends along the first direction X and is disposed on the third folded edge 213 .

[0094] It should be noted that, unless there is any conflict, the features in the embodiments of this application can be combined with each other.

[0095] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application.
