Description

Technical Field

[0001] This invention relates to the field of hydraulic cylinder manufacturing technology, specifically to a cutting device and cutting method for hydraulic cylinder manufacturing. Background Technology

[0002] Hydraulic cylinders, as power components widely used in mechanical equipment, directly affect the stability and efficiency of the entire system through their performance and quality. In the production process of hydraulic cylinders, the cutting and processing of components is an indispensable key step, and the materials used are often magnetically attracted. For example, when using a disc cold-cutting blade for shearing operations, a large amount of debris is generated during cutting. This debris mainly originates from the cutting process of the material being cut. Due to the high-speed movement of the disc cutter separating from the material during cutting, the debris cut from the disc cutter easily spreads into the surrounding environment in the form of centrifugal tangential splash. This phenomenon not only causes a large amount of debris to be scattered on the surface of the cutting equipment and its surrounding area, increasing the difficulty and time cost of subsequent cleaning, but also poses a potential threat to the health and safety of operators. Furthermore, the random splashing of debris makes centralized collection difficult; existing cutting devices often lack effective debris collection mechanisms, making it difficult to achieve timely management and control of debris during the cutting process.

[0003] Meanwhile, to ensure the cutting quality and extend the life of the disc cutter, cooling water is typically used to cool the cutting area during the cutting process. However, the debris splattered from the disc cutter mixes with the cooling water, requiring it to undergo a complex filtration system to remove solid impurities before it can be recycled. This process not only increases the workload of the filtration components but may also reduce filtration efficiency due to debris accumulation, or even cause clogging of the filtration system, thus affecting the recycling efficiency of the cooling water. Summary of the Invention

[0004] The purpose of this invention is to provide a cutting device and method for hydraulic cylinder production, which solves the problems of flying debris, difficulty in collecting debris, and heavy burden on the filtration system.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution: The present invention includes a cutting table saw with a telescopic structure. A circular saw is provided on the telescopic structure for cutting the workpiece and throwing out debris. The telescopic structure has a protective shell covering the circular saw blade. A flow-guiding component is provided on the protective shell, which is correspondingly set on the centrifugal tangent line of the circular saw blade throwing out debris. A water supply device is connected to the protective shell to deliver cooling water. The cooling water is guided through the flow-guiding component to form a water curtain on one side of the protective wing.

[0006] Preferably, the telescopic structure includes a frame, on which a telescopic device is mounted, the telescopic end of the telescopic device is connected to a mounting component, and the circular saw is fixed to the mounting component;

[0007] The protective shell is fixed to the mounting component, and the protective shell has downwardly extending protective wings, which are correspondingly positioned on the centrifugal tangential line of the debris thrown out by the disc saw blade.

[0008] The drainage component includes an elastic pad fixed to the protective shell and wings. A fence plate is provided on the upper side of the elastic pad and fixed to the protective shell. There is a gap between the elastic pad and the fence plate. Cooling water passes through the gap to form a water curtain to receive the debris thrown out by the disc saw and form a buffer. A plastic folding plate is fixed on the wings to be close to the part to be processed and guide the cooling water to the cutting point of the part to be processed.

[0009] Preferably, it also includes a support frame having a U-shaped groove and multiple sets of supports that slide therein, with spacing between any set of supports, forming a support position above the multiple sets of supports.

[0010] Preferably, a walking frame is movably mounted on the lifting frame, and the walking frame magnetically attracts one end of the part to be processed and drives it to rotate;

[0011] The traveling frame includes a pushing frame platform, which is slidably mounted on a support frame. A translator is provided on the lower side of the support frame to drive the pushing frame platform to move on the support frame. An adjustable motor is provided on the pushing frame platform. A magnetic head is fixed on the output end of the motor to magnetically fix the end of the part to be processed. The magnetic head is driven by the motor to rotate the magnetically attracted part to be processed.

[0012] Preferably, a locking frame is movably provided on the upper side of the lifting frame, the locking frame being used to abut against the receiving processing component and restrict its axial movement or rotation in the lifting position;

[0013] The locking frame includes an I-beam frame, a second telescopic device, and a ball head. The I-beam frame is slidably mounted on the lifting frame, and the second telescopic device is fixed on the I-beam frame. The telescopic end of the second telescopic device is connected to a ball head.

[0014] Preferably, a monitoring frame is provided on the upper side of the lifting frame. The monitoring frame is located at one end of the part to be cut off. The monitoring frame monitors the falling of the part to be cut off and then delays the start of the translation device.

[0015] The monitoring frame includes a support frame, an adjusting block, and a monitoring probe. The support frame is slidably mounted on the support frame. The support frame is equipped with an adjusting block that can be adjusted up and down. The adjusting block is equipped with a monitoring probe for monitoring the part of the workpiece being cut. The monitoring frame is equipped with a PLC, which is electrically connected to the monitoring probe.

[0016] Preferably, one end of the lifting frame is connected to a receiving box, and an adjustment box located below the lifting position is provided inside the lifting frame. The adjustment box is connected to one end of the receiving box and receives the debris and cooling water generated by the part to be processed.

[0017] Preferably, the receiving box includes a water storage tank fixed to one end of the lifting frame. The water storage tank contains coolant and has a partition plate fixed inside. There is a gap between the lower end of the partition plate and the bottom of the water storage tank, forming a U-shaped cavity inside the water storage tank. A movable block located in one side of the partition plate is slidably disposed on the partition plate. A positioning element is rotatably connected to the movable block to receive the processing part. The positioning element moves with the part of the processing part that is being cut. A floating counterweight plate is fixed on the movable block. The floating counterweight plate slides up and down in the other side of the partition plate cavity along with the positioning element. When the floating counterweight plate moves down, the coolant in one side of the U-shaped cavity is pressurized to the other side, and the coolant level in the other side cavity rises, forming a surge that moves toward the other end of the adjustment box to push away the generated debris.

[0018] Preferably, the adjustment box includes a U-shaped groove fixed inside the support frame. An adjustment plate is provided on the inner side of the U-shaped groove. Multiple adjustment columns are connected to the adjustment plate. The adjustment plate is adjusted up and down by the multiple adjustment columns to change the distance between the adjustment plate and the part to be processed. An electromagnetic suction strip is provided on the lower side of the adjustment plate to magnetically attract the chips from the part to be processed. The electromagnetic suction strip magnetically attracts and gathers the chips to form a chip brush to adhere to the surface of the part to be processed.

[0019] A cutting method for manufacturing hydraulic cylinders, using the aforementioned cutting device for hydraulic cylinder manufacturing, comprises the following steps:

[0020] Step 1: Place the part to be processed on the support frame and lift it, avoiding the cutting area to ensure that the cut part can fall; adjust the part to be processed; lift the positioning part to a reasonable height for docking with the part to be processed, and drive the part to be processed to dock with it.

[0021] Step 2: Start the circular saw and align it with the cutting area; cooling water is supplied by the water supply unit to the protective shell and forms a water curtain through the diversion component; the generated debris is buffered by the water curtain and falls into the adjustment box with the cooling water;

[0022] Step 3: Utilizing the falling of the cut section, the cooling water in the U-shaped cavity of the receiving box is pressurized to form a surge, which pushes the debris to be adsorbed and accumulated to form a debris brush, which assists in cleaning the surface;

[0023] Step 4: Turn off the water supply and the circular saw, and remove the remaining parts to be processed; clean the debris and cooling water from the adjustment box, and prepare for the next workpiece.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. The protective shell and drainage components on the table saw, along with the protective wings and water curtain design, intercept the debris thrown out during cutting, preventing it from splashing onto the equipment surface and surrounding environment. The slope of the elastic pad guides the water flow, and the highly elastic sponge material further cushions the impact of debris. Combined with the shaped baffle plate guiding debris and cooling water into the adjustment box, this significantly reduces the debris scattering area, lowers the difficulty and time cost of subsequent cleanup, and improves the safety of the working environment.

[0026] 2. The device utilizes the synergistic effect of the receiving box and the adjusting box, along with the surging waves generated by the falling floating counterweight plate, to push debris from the cutting side towards the electromagnetic suction bar for concentrated adsorption. The electromagnetic suction bar remains energized during operation, continuously adsorbing debris and forming a debris brush. This not only achieves efficient and concentrated debris collection but also assists in surface cleaning through the dynamic contact between the debris brush and the workpiece surface, significantly reducing the labor intensity of manual cleaning and improving production efficiency.

[0027] 3. The water curtain formed by the flow-guiding component precisely cools the cutting area, while simultaneously guiding cooling water and debris into the adjustment box. The surging waves push the debris to the electromagnetic suction strip for adsorption, reducing the amount of debris mixed in the coolant. Compared to traditional technologies where cooling water needs to pass through a complex filtration system to remove large amounts of debris, this invention, through centralized processing and pre-adsorption of debris, allows the coolant to be reused with only simple filtration before circulation, significantly reducing the workload of the filtration components and improving the operating efficiency and economy of the cooling system.

[0028] 4. The lifting frame, in conjunction with the traveling frame and locking frame, uses magnetic suction heads and ball bearing heads to securely fix the workpiece to be processed and adjust it at multiple angles, ensuring stable workpiece position during cutting and avoiding cutting errors caused by vibration or movement. The translation device uses a grating ruler to measure the stroke, precisely controlling the moving distance of the pushing frame, further improving the accuracy of the cutting position and the flexibility of multi-segment cutting.

[0029] 5. The monitoring frame is equipped with a reflective photoelectric sensor and a PLC control system, which can detect the cutting status in real time and automatically start the translation device through a delay program to adjust the workpiece to the next cutting position, reducing manual intervention. The drive adjustment structure is linked with the PLC to automatically lift the positioning part to complete the initial docking and then fall back, realizing the automated connection of workpiece installation, cutting and part removal, which significantly improves the continuity of the production line and processing efficiency.

[0030] 6. Both expansion joints 1 and 2 employ electric push rods with adjustable thrust, accommodating parts of varying sizes and weights. The adjusting plates, via adjusting columns, allow for flexible height adjustment, ensuring compatibility between the workpiece and coolant. Controlled and centralized collection of debris reduces the risk of operator contact with debris, enhancing operational safety. Attached Figure Description

[0052] The above-mentioned and other technical features and advantages of the present invention will be described in more detail below with reference to the accompanying drawings.

[0053] Example

[0054] This embodiment provides a technical solution: a cutting device for hydraulic cylinder production, such as... Figure 1-13As shown, the table saw includes a cutting table saw 2 with a frame 21, which is welded from high-strength steel to provide a stable support structure. An extension joint 22 is mounted on the frame 21. In this embodiment, the extension joint 22 uses an electric push rod design, providing precise linear displacement control. Its extension position can be adjusted by the control system according to cutting requirements. As an alternative, the extension joint 22 can also be replaced with a hydraulic cylinder. Its extension end is connected to a mounting component 23. Through the up-and-down adjustment of the extension joint 22, the mounting component 23 can achieve precise positioning of the circular saw 24 in the vertical direction. The mounting component 23 is a rigid connecting plate on which the circular saw 24 is fixed. The circular saw 24 consists of a high-speed motor and a rotating circular saw blade, which is existing technology; it is used to cut the workpiece and eject debris during the cutting process. To effectively control debris splashing, the mounting component 23 is equipped with a protective shell 25 that covers the blade of the circular saw 24. The protective shell 25 is made of corrosion-resistant stainless steel and has downward-extending protective wings, the length of which can be designed according to requirements. It is positioned on the horizontal centrifugal tangential line of the circular saw 24 blade to intercept the debris ejection path to the greatest extent. A flow guiding component is provided on the protective wings to guide coolant to form a water curtain to provide a buffer barrier for ejected debris. A water supply device 29 is connected to the top of the protective shell 25. The water supply device 29 uses existing water pumps and water pipes and has a filter structure (not shown in the figure, using existing technology). The water pipe of the water supply device 29 is connected to the protective shell 25, and the water supply device 29 delivers coolant through the pipes. It is equipped with a flow regulating valve, which can be flexibly adjusted according to cutting requirements.

[0055] Optionally, the drainage component includes an elastic pad 26 fixed to the wing of the protective shell 25. The elastic pad 26 is made of highly elastic sponge material, and its surface is designed with a sloping structure with an inclination angle of 10-20 degrees to ensure that the coolant forms a stable water curtain when flowing. A fence plate 27 fixed to the protective shell 25 is provided on the upper side of the elastic pad 26. The fence plate 27 is a bent metal plate, which, together with the wing, forms a water-retaining enclosure. A gap of 2-5 mm is reserved between the fence plate 27 and the elastic pad 26; in this embodiment, 4 mm is selected to ensure uniform coolant flow. The cooling water supplied by the water supply device 29 first accumulates within the fence plate 27 and the wing enclosure, and then flows through the gap and the sloping surface of the elastic pad 26 to form a water curtain of uniform thickness. This water curtain not only buffers the debris thrown by the disc saw 24 but also effectively reduces the debris splash range. Furthermore, the elastic pad 26, made of elastic sponge material, provides additional cushioning when debris impacts, reducing debris rebound. The protective wing is also fixed with a shaping folding plate 28, which is made of flexible rubber material with a thickness of about 3-5 mm. A bendable metal sheet with a thickness of 0.5 mm is attached to the outside. By manually adjusting the shape of the metal sheet, the shaping folding plate 28 is brought close to the surface of the part to be processed, thereby guiding the cooling water to flow precisely to the cutting area and achieving effective cooling of the cutting part.

[0056] Optionally, the system also includes a support frame 1, which is an integral support structure with a U-shaped channel frame 11. The U-shaped channel frame 11 is made of channel steel and has multiple guide rails to accommodate the sliding of various structural components. Multiple sets of supports 12 are slidably installed inside. Each set of supports 12 includes two movable blocks with ball bearings movably embedded on them, enabling axial movement and rotation. The supports 12 are spaced apart, the size of which is designed according to the diameter and length of the part to be processed. The multiple sets of supports 12 together form a support position, ensuring the horizontal stability of the part to be processed during the cutting process. The supports 12 can be adjusted within the U-shaped channel frame 11 via manual or automatic slide rails to avoid the cutting area, ensuring that the cut portion falls smoothly.

[0057] Optionally, a traveling frame 3 is movably mounted on the lifting frame 1. The traveling frame 3 magnetically attaches one end of the workpiece to be processed and drives it to rotate, allowing for flexible adjustment of the cutting angle. It should be noted that the rotation axis must be kept aligned during magnetic attachment to ensure stable rotation. The traveling frame 3 includes a sliding platform 31, which is a frame structure with a slider at the bottom. This slider cooperates with the guide rail of the U-shaped slot frame 11 to achieve sliding movement on the lifting frame 1. A translator 34 is located on the lower side of the lifting frame 1. The translator 34 is a reciprocating screw structure, equipped with a servo motor drive, and integrates a grating ruler as a stroke measurement sensor. The measurement accuracy can reach ±0.01 mm, enabling precise control of the moving distance and speed of the sliding platform 31. The sliding platform 31 is equipped with an adjustable motor 32, a DC brushless motor. The height is adjustable via a bolt-locking structure or a screw-lifting mechanism, with the adjustment range customizable. A magnetic head 33, an electromagnet with a diameter set according to requirements, is fixed to its output end. When energized, the magnetic head 33 generates magnetic force to attract the end of the workpiece. The motor 32 drives the magnetic head 33 to rotate, causing the workpiece to rotate at a speed of 0-60 revolutions per minute, facilitating multi-angle cutting by the circular saw 24.

[0058] Optionally, a locking frame 4 is movably installed on the upper side of the lifting frame 1. The locking frame 4 is used to abut the receiving workpiece, restricting it to the lifting position to prevent axial movement or accidental rotation and ensure cutting accuracy. The locking frame 4 includes an I-beam 41, which is an I-shaped steel component with a groove at the bottom, slidably connected to the lifting frame 1, and its position can be adjusted along the length of the workpiece. A telescopic device 42 is fixed on the I-beam 41. The telescopic device 42 adopts an electric push rod design, and its telescopic position can be precisely adjusted through an electronic control system. As an alternative, the telescopic device 42 can also be replaced with a hydraulic cylinder to provide higher clamping force. The telescopic end of the telescopic device 42 is connected to a ball head 43, which is made of a cylinder and a high-hardness steel ball that is movably embedded therein. The ball head 43 has a smooth surface, which can reduce friction when abutting the workpiece, and at the same time, the pressure of the telescopic device 42 achieves stable clamping of the workpiece.

[0059] Optionally, a monitoring frame 5 is installed on the upper side of the lifting frame 1. The monitoring frame 5 is located at the pre-cut end of the workpiece to be processed and is used to monitor the completion status of the cutting. The monitoring frame 5 includes a vertical support 51, which is a bridge-type support and is slidably mounted on the lifting frame 1 at the bottom. It is equipped with locking bolts to adjust its position along the workpiece axis. An adjustable block 52 is installed on the vertical support 51. The adjustable block 52 is fixed by bolts, and the adjustment range is set according to the height of the vertical support 51. A monitoring probe 53 is installed on the adjustable block 52. The monitoring probe 53 is a reflective photoelectric sensor that emits an infrared beam. When the workpiece to be processed is not cut, the beam is blocked by the workpiece; after cutting, the beam forms a reflection loop and generates an electrical signal. The monitoring frame 5 also integrates a PLC, which is electrically connected to the monitoring probe 53. After receiving the electrical signal according to a preset program, the PLC starts the translation device 34 after a delay. The delay time is adjustable from 5 to 10 seconds so that the cut part can be removed manually or by a robotic arm.

[0060] Optionally, one end of the lifting frame 1 is connected to a receiving box 6, and an adjustment box 7 is provided inside the lifting frame 1 located on the lower side of the lifting position. The adjustment box 7 is connected to one end of the receiving box 6 to jointly receive the debris and cooling water generated by the cutting of the part to be processed.

[0061] The receiving box 6 includes a water storage tank 61 fixed to one end of the lifting frame 1. The water storage tank 61 contains coolant, and a partition plate 62 is fixed inside the water storage tank 61. The lower end of the partition plate 62 and the bottom of the water storage tank 61 form a U-shaped cavity. A movable block 63 is slidably mounted on the partition plate 62 through an elongated groove. A positioning element 64 is rotatably connected to the movable block 63. The positioning element 64 consists of a support plate and multiple circumferentially spaced triangular plates. The inclined sides of the triangular plates provide guidance, and the circumferential axis formed by the multiple triangular plates is coaxial with the rotating positioning element 64, and it moves as the cutting part falls. A floating counterweight plate 65 is fixed to the other side of the movable block 63. The floating counterweight plate 65 slides up and down in the cavity on the other side of the U-shaped cavity. When the cutting part falls, causing the positioning element 64 and the floating counterweight plate 65 to move downward, the coolant on one side of the U-shaped cavity is pressurized and flows to the other side, the liquid level rises and a surge is formed, and the surge pushes the debris along the direction of the adjusting box 7. The water storage tank 61 is externally connected to a drive adjustment structure (not shown in the figure). The drive adjustment structure is a stepper motor driven lifting platform, which is used to initially push the positioning part 64 to a reasonable height to dock with the part to be processed, but is not fixedly connected to the positioning part 64. After the lifting is completed, it automatically falls back to the initial position.

[0062] The adjustment box 7 includes a U-shaped groove 71 fixed inside the support frame 1. The U-shaped groove 71 has a cooling water level approximately two-thirds full, at the same level as the water tank 61, which can be adjusted according to actual needs. The water tank 61 can supply water to the water supply device 29. An adjustment plate 72 is provided inside, which is adjusted up and down by multiple adjustment columns 73 (using a screw adjustment mechanism with a pitch of 2 mm) to change the distance to the workpiece, ensuring that the workpiece is partially submerged in coolant when placed horizontally. An electromagnetic suction strip 74 is fixed below the adjustment plate 72. The electromagnetic suction strip 74 is narrower than the adjustment plate 72. When energized, it generates magnetic force to attract debris. The accumulated debris forms a debris brush that adheres to the workpiece surface and assists in cleaning when the workpiece rotates or moves. A gap is left between the electromagnetic suction strip 74 and the inner wall of the U-shaped groove 71 to avoid obstructing the flow of swells.

[0063] In this embodiment, when the workpiece to be processed is cut using this solution, the specific working principle is as follows: First, the workpiece to be processed (usually a metal rod or pipe of a hydraulic cylinder) is placed on the U-shaped groove frame 11 of the lifting frame 1. Multiple sets of supports 12 slide and position along the guide rail according to the length of the workpiece and the cutting position, ensuring that the lifting position stably supports the workpiece, while avoiding the predetermined cutting part so that the cut part falls. Subsequently, the pushing frame 31 of the traveling frame 3 slides to one end of the workpiece through the translation device 34 (reciprocating screw structure, equipped with a grating ruler to measure the stroke, with an accuracy of ±0.01 mm). The motor 32 drives the magnetic suction head 33 to generate magnetic force, adsorbing and fixing the end of the workpiece, and the workpiece angle can be adjusted by rotating the motor 32. The I-beam frame 41 of the locking frame 4 slides, and the telescopic device 42 (electric push rod) pushes the ball head 43 to abut against the surface of the workpiece, applying clamping force to restrict the axial movement or rotation of the workpiece in the lifting position, ensuring stability during the cutting process.

[0064] Then, the cutting process is performed by the table saw 2. The telescopic device 22 (electric push rod) on the frame 21 adjusts the height of the mounting piece 23 so that the saw blade of the circular saw 24 is aligned with the cutting area of ​​the workpiece. After the circular saw 24 is started, it rotates at high speed to cut the workpiece, producing metal chips. The chips are thrown out along the horizontal tangent due to centrifugal force, but are intercepted by the protective wings of the protective shell 25. The water supply device 29 provides a certain flow of cooling water to the protective shell 25. The coolant accumulates in the enclosure plate 27 and the protective wing enclosure, and then flows out through the gap between the elastic pad 26 and the enclosure plate 27, forming a water curtain on the slope of the elastic pad 26. The water curtain cools the cutting area of ​​the circular saw 24 and the workpiece on the one hand, and buffers the splashing of chips on the other hand. The elastic pad 26, made of elastic sponge material, further absorbs the impact force of the chips. The shaping folding plate 28 adjusts the shape of the rubber by manually bending the metal sheet, close to the surface of the workpiece, and guides the water curtain and chips to fall along the workpiece towards the downward adjustment box 7, effectively reducing chip scattering.

[0065] After the circular saw 24 completes the cut, the cut portion falls due to gravity, causing the positioning component 64 in the receiving box 6 to move downwards as well. The positioning component 64 pulls the floating counterweight plate 65 down the U-shaped cavity via the moving block 63, squeezing the coolant on one side and causing the liquid to flow through the gap at the lower end of the partition plate 62 to the other side, raising the liquid level and forming a surge. The surge pushes the debris along the direction of the adjusting box 7, flowing from the cutting side to the other side. Before cutting, the adjusting plate 72 of the adjusting box 7 is adjusted in height via the adjusting column 73 to ensure that the workpiece is partially immersed in the coolant. Throughout the operation, the electromagnetic suction bar 74 remains energized, continuously generating magnetic force. When the debris carried by the surge passes through the electromagnetic suction bar 74, the debris is attracted and gradually accumulates. Because the electromagnetic suction bar 74 is always energized, the adsorbed debris continuously accumulates to form a stable debris brush. When the debris brush is thick enough to approach the workpiece surface, the workpiece rotates under the drive of motor 32 and moves under the push of the translation device 34, bringing the debris brush into contact with the workpiece surface and assisting in cleaning the surface. The width of the electromagnetic suction bar 74 is smaller than the width of the adjusting plate 72, leaving a gap between it and the inner wall of the U-shaped groove 71 to ensure that the flow of surge waves is not obstructed.

[0066] Meanwhile, the monitoring probe 53 (reflective photoelectric sensor) of the monitoring frame 5 monitors the cutting status. Before cutting, the sensor beam is blocked by the workpiece; after cutting, the beam forms a reflection loop, generating an electrical signal that is transmitted to the PLC. The PLC delays for 5 to 10 seconds according to the preset program, waiting for the cut part to be removed by the robotic arm or manually, and then starts the translator 34 to push the moving frame 31 to move a set distance, aligning the next cutting part with the circular saw 24.

[0067] Finally, before the cut section falls, the external drive adjustment structure (stepper motor driven lifting platform) of the receiving box 6 pushes the positioning component 64 to the docking position with the workpiece, and then falls back without connecting to the positioning component 64, ensuring that the falling process is driven only by the gravity of the cut section. After the part to be processed is cut, the PLC controls the translation device 34 to adjust the position of the workpiece. If cutting is required to continue, the above cutting work is repeated; if cutting is completed, the water supply device 29 and the circular saw 24 are turned off, the power of the electromagnetic suction strip 74 is disconnected to release the debris brush, the magnetic suction head 33 and the locking frame 4 are released, and the processed workpiece is taken out. The debris and cooling water in the adjustment box 7 and the receiving box 6 are cleaned regularly. The coolant is recycled after simple filtration. Because the debris is collected by the electromagnetic suction strip 74, the filtration burden is significantly reduced.

[0068] A method for cutting hydraulic cylinders during production, using a hydraulic cylinder cutting device, includes the following steps:

[0069] Step 1: Place the part to be processed on the lifting frame 1 and lift it, avoiding the cutting part to ensure that the cut part can fall; adjust the part to be processed; lift the positioning part 64 to a reasonable height for docking with the part to be processed, and drive the part to be processed to dock with it.

[0070] In conjunction with the entire contents of this embodiment, the specific steps are as follows: The part to be processed is placed on the U-shaped groove frame 11 of the lifting frame 1, and is supported by multiple sets of supports 12, avoiding the cutting area to ensure that the cut part can fall; the walking frame 3 is adjusted, and the magnetic suction head 33 is driven by the motor 32 to magnetically fix one end of the part to be processed; the locking frame 4 is activated, and the ball head 43 is driven by the telescopic device 42 to abut against the part to be processed, restricting its ability to move only axially or rotate; the upright frame 51 and the adjusting block 52 of the monitoring frame 5 are adjusted so that the monitoring probe 53 is aligned with the cutting area and the light is blocked by the workpiece; the structural lifting positioning component 64 is adjusted to a reasonable height to dock with the part to be processed, and the part to be processed is driven to dock with it by adjusting the walking frame 3;

[0071] Step 2: Start the circular saw 24 and align it with the cutting area; cooling water is supplied by the water supply unit 29 to the protective shell 25 and forms a water curtain through the diversion component; the generated debris is buffered by the water curtain and falls into the adjustment box 7 with the cooling water;

[0072] In conjunction with the entire contents of this embodiment, the specific steps are as follows: Start the cutting table saw 2, adjust the position of the mounting piece 23 through the telescopic device 22, and align the circular saw 24 with the cutting area; turn on the water supply device 29 to supply cooling water to the protective shell 25. The cooling water accumulates under the fence plate 27 and the protective wing barrier, and flows out through the gap between the elastic pad 26 and the fence plate 27, forming a water curtain on the slope of the elastic pad 26; manually bend the outer metal sheet of the plastic folding plate 28 to bring the rubber sheet close to the part to be processed, guiding the water curtain to the cutting position; start the circular saw 24 to cut, and the generated debris is buffered by the water curtain and falls into the adjustment box 7 with the cooling water;

[0073] Step 3: The falling of the cut section causes the cooling water in the U-shaped cavity of the receiving box 6 to be pressurized, forming a surge that pushes the debris to be adsorbed and accumulated to form a debris brush, which assists in cleaning the surface.

[0074] In conjunction with the entire contents of this embodiment, the specific details are as follows: After the cutting is completed, the cut part falls, which drives the positioning part 64 and the floating counterweight plate 65 to fall. The cooling water in the U-shaped cavity is pressurized to form a surge wave, which pushes the debris from the cutting part side of the adjustment box 7 to the other side. The monitoring probe 53 detects the falling of the cut part, and the light forms a reflection circuit, generating an electrical signal that is transmitted to the PLC. When the debris pushed by the surge wave passes through the electromagnetic suction bar 74, it is attracted and accumulates to form a debris brush. The part to be processed rotates under the drive of the motor 32, and the debris brush assists in cleaning the surface.

[0075] Step 4: Turn off the water supply 29 and the circular saw 24, and remove the remaining parts to be processed; clean the debris and cooling water from the adjustment box 7, and prepare for the next workpiece.

[0076] In conjunction with the entire content of this embodiment, the specific steps are as follows: The PLC delays according to the set program to remove the cut part. After the delay, the electrically controlled translator 34 pushes the translating frame 31 to move a set distance, aligning the next cutting part with the disc saw 24; the cut part is removed; if cutting needs to continue, steps two to four are repeated; if cutting is completed, the water supply 29 and the disc saw 24 are turned off, the magnetic suction head 33 and the locking frame 4 are released, and the remaining parts to be processed are removed; the debris and cooling water in the adjustment box 7 are cleaned, and the next workpiece is prepared.

[0077] The above description is merely a preferred embodiment of the present invention and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, all of which will fall within the protection scope of the present invention.
