Description

Technical Field

[0001] This invention relates to the field of sawing equipment technology, specifically a sawing equipment for forging processing. Background Technology

[0002] In the forging processing industry, sawing is a common blanking or segmentation process. Its processing efficiency, cutting accuracy, and operational safety directly affect the quality and cost of subsequent processes. Currently, most common forging sawing equipment uses manual material feeding and manual clamping, which is not only labor-intensive and inefficient, but also prone to material misalignment and vibration, affecting the flatness and dimensional accuracy of the cut surface. Furthermore, the high temperatures generated during sawing can accelerate tool wear and workpiece surface hardening, while also producing large amounts of metal shavings and dust, adversely affecting the working environment and the health of operators.

[0003] While some sawing equipment in the present technology is equipped with simple cooling or dust removal devices, the utilization rate of coolant is often low and the waste collection is inadequate, resulting in coolant waste and environmental pollution. In addition, material feeding mostly relies on manual labor or simple propulsion mechanisms, making it difficult to achieve accurate and stable automatic feeding. Especially for heavy and irregularly shaped forgings, positioning and clamping remain major challenges. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a sawing device for forging processing. It solves the problems of existing technologies where, although some sawing equipment is equipped with simple cooling or dust removal devices, the coolant utilization rate is often low and waste collection is inadequate, leading to coolant waste and environmental pollution. Furthermore, material feeding largely relies on manual labor or simple propulsion mechanisms, making it difficult to achieve precise and stable automatic feeding. Positioning and clamping remain significant technical challenges, especially for heavy and irregularly shaped forgings.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sawing device for forging processing, comprising a worktable, a sawing machine, and a baffle for pushing material feed. The worktable is provided with a drive assembly for driving the baffle to reciprocate along the length of the worktable.

The telescopic end of the electric push rod is provided with a clamping block. A waste collection assembly is provided on the lower wall of the worktable.

[0006] In some embodiments, the drive assembly includes a pair of housings, which are arranged parallel to each other on the worktable along its length. A lead screw is rotatably mounted inside each housing along its length. Openings are respectively provided on the opposite walls of the pair of housings along their length. I-shaped blocks are slidably mounted in the openings. The I-shaped blocks are threadedly connected to the lead screw. A baffle is fixedly installed between the I-shaped blocks. A drive unit that simultaneously drives the lead screw to rotate is provided between the pair of housings.

[0007] In some embodiments, the drive unit includes a protective housing, which is fixedly installed on the lower wall of the workbench. A first motor is fixedly installed on the lower wall of the protective housing, and a first sprocket is fixedly installed on the drive end of the first motor. A shaft is rotatably installed on the upper wall of the protective housing, with the upper end of the shaft passing through the housing. A drive gear is fixedly installed on the upper end of the shaft, and a driven gear is fixedly installed on the lead screw. The drive gear and the driven gear are meshed and connected. A second sprocket is fixedly installed on the lower end of the shaft, and a chain connects the first sprocket and the second sprocket.

[0008] In some embodiments, a third sprocket for tensioning the chain is provided between the first sprocket and the second sprocket.

[0009] In some embodiments, the pressing assembly includes a cylinder body, which is fixedly mounted on a sawing machine. A through hole is provided on the lower wall of the cylinder body, and a support rod is inserted into the through hole. The upper end of the support rod is located inside the cylinder body and a piston plate is fixedly mounted thereon. A spring is provided between the piston plate and the cylinder body, and a pressure plate is hinged to the lower end of the support rod.

[0010] In some embodiments, the waste collection assembly includes a collection box fixedly installed on the lower wall of the workbench. A second motor is fixedly installed on the rear wall of the collection box, with the drive end of the second motor passing through the collection box. A central rod is fixedly installed on the drive end of the second motor, and a spiral blade is fixedly installed on the central rod. An L-shaped filter screen is fixedly installed inside the collection box. A discharge port is provided on the front wall of the collection box for discharging waste. A liquid outlet pipe is fixedly installed on the lower wall of the collection box and connected to a water tank.

[0011] In some embodiments, the lower wall of the collection box has a funnel-shaped structure.

[0012] In some embodiments, the worktable has a groove, and a plurality of rotating rollers are arranged in parallel within the groove.

[0013] In some embodiments, the lower wall of the groove is sloped to allow liquid in the groove to flow back into the collection tank.

[0014] Beneficial effects: This invention provides a sawing device for forging processing, which has the following advantages: 1. Automated and precise material feeding: By setting up a drive assembly consisting of a motor, sprocket, gear, and lead screw, the baffle can be automatically driven to move smoothly and synchronously back and forth along the length of the worktable, thereby replacing manual pushing and realizing automated feeding of forging materials. This not only significantly reduces labor intensity and improves production efficiency, but also ensures the accuracy and consistency of the feeding position, laying the foundation for subsequent precise cutting.

[0015] 2. Ensures stability and precision in the cutting process: By setting up a sawing machine with cylinder-controlled lifting and lowering, and combining it with a pressing component with elastic clamping function, the material can be self-adaptively clamped by the pressure plate when the sawing machine falls, and a continuous and flexible clamping force is provided under the action of the spring. This effectively prevents the material from shifting, jumping or vibrating during the cutting process, greatly improving the quality and dimensional accuracy of the cut surface, while also enhancing operational safety.

[0016] 3. Effectively improves the processing environment and extends tool life: By setting up a cooling spray system consisting of a water tank, water pump and nozzle, coolant can be continuously sprayed onto the cutting area during sawing, which can effectively cool down, lubricate and suppress dust; this can not only inhibit dust diffusion and improve the working environment, but also significantly reduce cutting temperature, reduce tool wear and extend saw blade life.

[0017] 4. Achieves efficient separation and automatic processing of waste and coolant: By setting up a waste collection component under the workbench, especially by using an L-shaped filter screen to achieve solid-liquid separation, and using spiral blades to automatically push solid waste out of the discharge port, the collected coolant can be returned to the water tank for recycling through the outlet pipe; this design achieves automatic collection, separation and discharge of waste, as well as recycling and reuse of coolant, reducing resource waste and environmental pollution, and keeping the work area clean.

[0018] 5. Optimized material handling and positioning, improving overall operational smoothness: The groove with rotating rollers on the workbench facilitates the movement and initial positioning of heavy forging materials; combined with the electric push rod and clamping block on the support beam, the material can be assisted in clamping and centering before cutting, further ensuring positioning accuracy; the slope at the bottom of the groove facilitates the return of liquid to the collection box, further enhancing the coolant recovery and workbench cleaning effect.

[0019] 6. Reasonable structural design and high degree of automation and integration: This invention organically integrates functional modules such as automatic feeding, stable pressing, cooling spraying, waste collection and recycling into one unit. The coordinated operation of each component significantly improves the automation level and overall operating efficiency of the equipment. Its compact structure and convenient operation make it suitable for large-scale and continuous forging processing production scenarios. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-8This invention provides a technical solution: a sawing device for forging processing, including a workbench 1, a sawing machine 2, and a baffle 3 for pushing material feed; the workbench 1 is provided with a drive assembly for driving the baffle 3 to reciprocate along the length of the workbench; a support beam 4 is provided above the workbench 1, and a cylinder 5 is installed on the support beam 4. The telescopic end of the cylinder 5 is connected to the sawing machine 2 for controlling the lifting and lowering of the sawing machine 2; the sawing machine 2 is provided with a pressing assembly for pressing the material during the cutting process; a water tank 6 is also provided on the support beam 4, and a water pump 7 is equipped on the water tank 6. A nozzle 8 connected to the water pump 7 is installed on the sawing machine 2 for spraying coolant during the sawing process to reduce the cutting temperature and reduce dust; a pair of electric push rods 9 are arranged opposite each other on the support beam 4, and a clamping block 10 is provided on the telescopic end of the electric push rod 9 for preliminary positioning and clamping of the material before cutting; a waste collection assembly is provided on the lower wall of the workbench 1 for collecting waste and coolant generated during cutting, realizing waste separation and coolant recovery.

[0026] In this embodiment, the drive assembly includes a pair of housings 11, which are fixed parallel to the length of the workbench 1. Each housing 11 has a lead screw 12 rotatably mounted inside it along its length. Openings 13 are respectively provided on the opposite walls of the pair of housings 11 along the length of the housings. I-shaped blocks 14 are slidably mounted in the openings 13 and are threadedly connected to the lead screws 12. A baffle 3 is fixedly installed between the two I-shaped blocks 14, so that the movement of the I-shaped blocks 14 drives the baffle 3 to move synchronously. A drive unit that simultaneously drives the two lead screws 12 to rotate is provided between the pair of housings 11 to ensure that the baffle 3 smoothly and synchronously propels the material.

[0027] A pair of housings 11 are fixed parallel and symmetrically on both sides of the material feeding path along the length of the workbench 1, providing a closed installation protection space and stable rotation support for the lead screw 12, while providing symmetrical double-end support points and dual-path driving force input for the baffle 3. Compared with the simple propulsion mechanism with traditional single-end drive, this symmetrical structure can make the pushing force evenly distributed at both ends of the baffle 3, solving the problems of baffle 3 deflection, jamming, and feed path skew that are easy to occur when pushing heavy forgings under single-end force. At the same time, it ensures that the guide axis of the feed motion is always perpendicular to the cutting reference plane of the sawing station, avoiding the risk of material feeding skew from the structural root.

[0028] The full-length opening 13 on the side wall of the housing 11 forms a sliding fit with the I-shaped block 14. On the one hand, it provides precise linear guidance for the full-stroke movement of the I-shaped block 14, and on the other hand, it forms a reliable circumferential limit for the I-shaped block 14, ensuring that the rotational motion of the lead screw 12 can be accurately converted into the linear feed motion of the I-shaped block 14. At the same time, the I-shaped section of the I-shaped block 14 forms a surface contact fit with the opening 13, which can withstand greater radial loads and off-center load moments. When pushing heavy, irregular forgings, it is not easy for structural deformation to occur, ensuring the stability of the transmission fit and the long-term accuracy maintenance.

[0029] The lead screw 12 and the I-shaped block 14 form a precision threaded transmission pair. Utilizing the high precision, self-locking, and strong controllability of the lead screw transmission, the feed displacement, feed speed, and start / stop position of the I-shaped block 14 can be precisely controlled. Compared with simple pushing mechanisms such as cylinders and hydraulic cylinders, this structure can achieve stepless speed regulation and micron-level feed position control. At the same time, it can reliably lock at any feed position to avoid material backward displacement caused by the reaction force of the forging during the pushing process, thus ensuring the precise controllability of the feeding position.

[0030] Using a single first motor 16 as the power source, combined with sprocket and chain drive and bevel gear meshing drive, the two lead screws 12 can rotate synchronously and in the same direction. There is no need to set up independent drive units and synchronous control systems for the two sets of lead screws 12. This structure eliminates the problem of asynchronous feeding caused by control errors and differences in power response between multiple drive units from the root. It ensures that the I-shaped blocks 14 at both ends of the baffle 3 maintain the same moving speed and displacement at any time, so that the baffle 3 always moves smoothly in a state parallel to the sawing reference plane, ensuring uniform force on the material pushing end face and avoiding material deflection or tilting during the pushing process.

[0031] The baffle 3 is fixedly installed between two I-shaped blocks 14 to form a push structure with rigid support at both ends. The push end face of the baffle 3 is perpendicular to the material feeding direction and can fully fit with the end face of the forging material. During the push process, the push force is evenly applied to the end face of the material, avoiding local deformation and surface scratches caused by point contact and line contact. At the same time, it can be adapted to push forging materials with different cross-sectional sizes, improving the versatility of the device.

[0032] Specifically, the drive unit includes a protective box 15 fixedly installed on the lower wall of the workbench 1; a first motor 16 is fixedly installed at the bottom inside the protective box 15, and a first sprocket 17 is fixedly installed on the output shaft of the first motor 16; a shaft 18 is rotatably installed on the upper wall of the protective box 15, and the upper end of the shaft 18 passes through the box body 11 and is fixedly installed with a drive gear 19; a driven gear 20 is fixedly installed on each lead screw 12, and the drive gear 19 and the driven gear 20 mesh to form a bevel gear transmission pair; a second sprocket 21 is fixedly installed at the lower end of the shaft 18, and the first sprocket 17 and the second sprocket 21 are connected by a chain 22; in order to further ensure smooth transmission and prevent the chain from loosening, a third sprocket 23 for tensioning the chain 22 is also provided between the first sprocket 17 and the second sprocket 21.

[0033] Using a single first motor 16 as the sole power source for the drive unit replaces the two independent power units of the traditional dual-drive scheme, eliminating the potential for synchronization errors from multiple power sources at the source. The chain drive pair enables long-distance, constant-ratio power transmission. Compared to the gear direct transmission structure, it can flexibly adapt to the span installation requirements of the worktable 1, with a higher installation fault tolerance. At the same time, the chain drive has the characteristics of large transmission torque, strong overload capacity, and good impact resistance, which can stably output the large driving force required for pushing heavy forgings. There is no slippage or loss of rotation during the start-up, stop, and variable load conditions of pushing forgings, ensuring the stability of power transmission.

[0034] As the core intermediate component for power transmission, shaft 18 receives the power from the chain drive pair and transmits it to the bevel gear drive pair. Through the bevel gear transmission structure in which the driving gear 19 simultaneously meshes with two driven gears 20, two things are achieved: first, a 90° reversal of rotational power is realized, which is compatible with the vertical installation space layout of the lead screw 12 and shaft 18; second, a single-path power is mechanically synchronously distributed to the two paths, without the need for additional synchronization control programs. The rotational synchronicity of the two lead screws 12 can be guaranteed solely through the mechanical meshing structure, which completely eliminates the problems of control errors, response delays, and speed fluctuations caused by dual-motor drives, resulting in asynchronous feeds and ensuring that the feed displacements at both ends of the baffle 3 are completely consistent.

[0035] The third sprocket 23 serves as the tensioning structure for the chain 22. It abuts against the side of the chain 22 between the first sprocket 17 and the second sprocket (21), forming a real-time and continuous tension constraint on the chain 22. It can effectively compensate for the elongation of the chain 22 caused by wear and stretching after long-term operation of the equipment, avoid the problems of tooth skipping, slippage, and loss of rotation caused by loose chain 22, ensure the consistency of speed and phase during power transmission, ensure that the rotation phase of the two lead screws 12 always remains synchronized, avoid the feed displacement error caused by transmission instability, and further ensure the positional accuracy of material feeding.

[0036] The pressing assembly includes a cylinder 24 fixedly mounted on the sawing machine 2; a through hole is provided on the lower wall of the cylinder 24, and a support rod 25 is inserted into the through hole; the upper end of the support rod 25 is located inside the cylinder 24, and a piston plate 26 is fixedly mounted thereon; a spring 27 is provided between the piston plate 26 and the inner wall of the top of the cylinder 24, and a pressure plate 28 is connected to the lower end of the support rod 25 by a hinge; when the sawing machine 2 descends to cut, the pressure plate 28 first contacts the material and provides continuous pressing force under the action of the spring 27, so as to avoid displacement or vibration of the material during the cutting process and improve cutting accuracy and safety.

[0037] Pre-clamping trigger stage: Cylinder 5 drives the sawing machine 2 to feed downwards, and the pressing component moves down synchronously with the sawing machine 2. The pressure plate 28 first contacts the upper surface of the forging to be cut. At this time, the saw blade of the sawing machine 2 has not yet contacted the workpiece, completing the non-impact pre-contact positioning and establishing a benchmark for subsequent clamping operations.

[0038] During the clamping force establishment stage: The sawing machine 2 continues to descend under the drive of the cylinder 5. At this time, the pressure plate 28 has already contacted the workpiece surface and cannot continue to move down. The support rod 25 is supported by the reverse force of the workpiece and slides upward along the through hole on the lower wall of the cylinder 24, which simultaneously drives the piston plate 26 to move upward, compressing the spring 27 between the piston plate 26 and the inner wall of the top of the cylinder 24. The elastic reaction force generated by the compression of the spring 27 is transmitted to the pressure plate 28 through the piston plate 26 and the support rod 25, forming a positive clamping force on the workpiece, and completing the pre-clamping lock before the saw blade contacts the workpiece.

[0039] The sawing process continues in an adaptive clamping phase: the sawing machine 2 continues to descend until the saw blade contacts the workpiece, officially starting the sawing operation; throughout the entire sawing feed process, the spring 27 is always in a compressed and energy-storing state, continuously providing a stable and adjustable flexible clamping force to the pressure plate 28; at the same time, the pressure plate 28 is hinged to the lower end of the support rod 25, and can swing adaptively around the hinge point, perfectly fitting the uneven and irregular upper surface of the forging, so that the clamping force is evenly distributed on the workpiece contact surface; even if the workpiece experiences slight vibration or deformation during the sawing process, the elastic deformation of the spring 27 can compensate for the displacement in real time, always maintaining effective clamping of the workpiece, and completely avoiding displacement, jumping or vibration of the workpiece.

[0040] Reset and release stage: After the sawing operation is completed, the cylinder 5 drives the sawing machine 2 to move upward to reset, the spring 27 gradually rebounds to release the pressure, and the pressure plate 28 moves upward synchronously with the sawing machine 2, smoothly separating from the workpiece surface, completing a complete pressing operation cycle, and preparing for the next sawing operation.

[0041] The waste collection assembly includes a collection box 29 fixedly installed on the lower wall of the workbench 1; a second motor 30 is fixedly installed on the rear wall of the collection box 29, the output shaft of the second motor 30 passes through the rear wall of the collection box 29, and a central rod is fixedly installed thereon; a spiral blade 31 is fixedly installed on the central rod; an L-shaped filter screen 32 is fixedly installed inside the collection box 29 for separating solid waste from coolant; a discharge port 33 is provided on the front wall of the collection box 29 for discharging solid waste; a liquid outlet pipe 34 is provided on the lower wall of the collection box 29, and the liquid outlet pipe 34 is connected to the water tank 6 through a pipe to realize the recycling of coolant; preferably, the lower wall of the collection box 29 is designed as a funnel-shaped structure to facilitate liquid collection and discharge.

[0042] To facilitate the movement and positioning of materials, a groove is provided on the workbench 1, and several rotating rollers 35 are arranged in parallel in the groove. Materials can be placed on the rotating rollers 35 and easily pushed into the cutting station. Furthermore, the lower wall of the groove is sloped, so that the coolant sprayed onto the workbench surface can flow back naturally into the collection box 29 along the slope, keeping the workbench surface clean and further improving the coolant recovery efficiency.

[0043] During the sawing operation, the coolant sprayed by nozzle 8 forms a solid-liquid mixture with the metal scraps generated during cutting. Under the action of gravity, the mixture falls completely into the collection box 29 fixed to the lower wall of the workbench 1 through the groove and discharge port, without spillage or overflow, thus completing the closed collection of waste and coolant. After entering the collection box 29, the solid-liquid mixture first falls onto the L-shaped filter screen 32. The aperture of the L-shaped filter screen 32 is smaller than the particle size of the metal scraps, which can completely intercept the solid metal waste on the surface of the filter screen. The coolant, under the action of gravity, flows through the filter screen holes into the bottom cavity of the collection box 29, completing the non-clogging and highly efficient solid-liquid separation of solid waste and coolant. The filtered coolant collects at the bottom of the collection box 29, and the lower wall of the collection box 29... The funnel-shaped structure of the surface allows the coolant to quickly converge to the outlet pipe 34 at the bottom center, and then flow back to the water tank 6 through the outlet pipe 34 and connecting pipe, completing the filtration, recycling and closed-loop circulation of the coolant, realizing the reuse of coolant and reducing resource waste. As the sawing operation continues, the metal debris intercepted on the L-shaped filter screen 32 accumulates continuously. At this time, the second motor 30 is started, and the motor output shaft drives the central rod and the spiral blade 31 to rotate synchronously. The rotating spiral blade 31 forms an axial conveying thrust, continuously and steadily pushing the solid waste accumulated on the filter screen to the discharge port 33 on the front wall of the collection box 29, and finally automatically discharged through the discharge port 33. There is no need for frequent manual shutdowns for cleaning, realizing automated slag discharge in continuous operation.

[0044] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0045] In the material loading and automated precision feeding stage: the forging material to be cut is placed on the rotating roller 35 in the groove of the worktable 1. The rotating roller 35 converts the sliding friction between the forging and the worktable into rolling friction, greatly reducing the pushing resistance of heavy forgings, and can easily complete the loading and initial positioning of the forgings; then the first motor 16 in the drive unit is started. The drive end of the first motor 16 drives the first sprocket 17 to rotate synchronously, and transmits the rotational power to the second sprocket 21 in a fixed ratio through the chain 22, thereby driving the shaft 18 to rotate synchronously; the drive gear 19 at the upper end of the shaft 18, through meshing with the driven gears 20 at the ends of the two lead screws 12, synchronously reverses and decomposes the single-path rotational power into two completely identical rotational outputs, driving the two lead screws 12 to rotate synchronously. The lead screw 12 rotates synchronously in the same direction and at the same speed within the housing 11. When the lead screw 12 rotates, the I-shaped block 14, which is threaded to it, is circumferentially limited by the opening 13 on the side wall of the housing 11, which accurately converts the rotational motion of the lead screw 12 into linear motion. This drives the baffle 3 between the two I-shaped blocks 14 to move smoothly and synchronously along the length of the worktable 1. Through the full contact between the pushing end face of the baffle 3 and the end face of the forging, the forging material is accurately pushed to the preset sawing station, completing the automated feeding operation. During this process, the third sprocket 23 always forms a tension constraint on the chain 22 to avoid transmission slippage and loss of rotation. This ensures the synchronicity of the dual lead screw feeding from the mechanical structure source and controls the positioning error of the material feeding within ±0.5mm.

[0046] Pre-clamping and centering stage: After the drive assembly pushes the forging material to the preset sawing station, the first motor 16 stops running and the drive assembly completes the feed lock; then, a pair of electric push rods 9 oppositely arranged on the support beam 4 are started. The electric push rods 9 on both sides synchronously drive the clamping blocks 10 at the telescopic end to move towards each other, completing the centering clamping and pre-positioning lock from both sides of the forging, completely eliminating the risk of position deviation after material feeding, and ensuring that the central axis of the forging is perpendicular to the cutting reference plane of the sawing machine 2, providing dual position guarantee for subsequent precise sawing.

[0047] Adaptive clamping and synchronous sawing operation stage: After the material pre-clamping and positioning is completed, the cylinder 5 on the support beam 4 is activated. The telescopic end of the cylinder 5 drives the sawing machine 2 to feed downward. The pressure assembly fixed on the sawing machine 2 moves down synchronously with the sawing machine 2. The pressure plate 28 of the pressure assembly contacts the upper surface of the forging first. At this time, the saw blade of the sawing machine 2 has not yet contacted the workpiece, completing the non-impact pre-contact. As the sawing machine 2 continues to move down, the pressure plate 28 stops moving down due to the reverse support force of the workpiece. The support rod 25 slides upward along the through hole of the cylinder 24, driving the piston plate 26 to compress the spring 27 in the cylinder 24. The elastic reaction force generated by the compression of the spring 27 is transmitted to the pressure plate 28 through the support rod 25, forming a continuous flexible clamping force on the forging. The hinge structure of the pressure plate 28 and the support rod 25 can adaptively fit the irregular surface of the forging, so that the clamping force is evenly distributed, and the full constraint pre-clamping lock is completed before the saw blade contacts the workpiece. The sawing machine 2 continues to descend until the saw blade contacts the forging, and the sawing machine 2 is started to officially start the sawing operation. Throughout the sawing feed process, the spring 27 is always in a compressed and energy-storing state. It compensates for the displacement of the sawing feed in real time through its own elastic deformation, providing a continuous and stable clamping force for the forging. At the same time, it absorbs the vibration and impact generated during the sawing process, prevents the workpiece from displacing, jumping, or vibrating, and ensures the stability and cutting accuracy of the sawing process.

[0048] Synchronous cooling and dust suppression stage: When the sawing machine 2 starts sawing operation, the water pump 7 on the water tank 6 is started simultaneously. The water pump 7 pressurizes the coolant in the water tank 6 and delivers it to the nozzle 8 on the sawing machine 2. The coolant is continuously and directionally sprayed onto the cutting contact area between the saw blade and the forging through the nozzle 8. On the one hand, the coolant quickly removes the cutting heat generated by sawing, reduces the temperature of the saw blade and the workpiece, avoids high-temperature wear of the saw blade and hardening of the workpiece surface, and extends the service life of the tool. On the other hand, it lubricates the cutting area, reduces sawing resistance, and inhibits the diffusion of metal dust, improves the working environment, and protects the health of the operators.

[0049] Waste collection and coolant closed-loop circulation stage: Metal scraps generated during sawing and coolant spraying form a solid-liquid mixture. Under gravity, the mixture falls through the material drop channel in the groove of the workbench 1 into the collection box 29 on the lower wall of the workbench 1. After entering the collection box 29, the solid-liquid mixture first contacts the L-shaped filter screen 32 inside the box. The L-shaped filter screen 32 completely intercepts the solid metal scraps above the filter screen, while the coolant flows through the filter screen holes into the bottom cavity of the collection box 29 under gravity, completing efficient solid-liquid separation. The funnel-shaped structure on the lower wall of the collection box 29 allows the filtered coolant to quickly converge to the outlet pipe 34 at the bottom, and then flow back to the water tank 6 through the outlet pipe 34 and connecting pipe, completing the filtration, recovery and closed-loop recycling of the coolant. Meanwhile, the slope of the lower wall of the groove of the workbench 1 can automatically guide the residual coolant sprayed onto the workbench surface to the collection box 29 along the slope. The flowing coolant will simultaneously wash the fine metal debris remaining on the workbench surface into the collection box, realizing the self-cleaning of the workbench surface and further improving the overall recovery rate of coolant. As the sawing operation continues, the metal debris intercepted on the L-shaped filter screen 32 accumulates. The second motor 30 on the rear wall of the collection box 29 is started. The drive end of the second motor 30 drives the central rod and the spiral blade 31 to rotate synchronously. Through the axial conveying thrust of the spiral blade 31, the solid waste accumulated on the filter screen is continuously and steadily pushed to the discharge port 33 on the front wall of the collection box 29, realizing the automated and continuous discharge of solid waste without the need for frequent manual shutdowns for cleaning, thus ensuring the continuity of production.

[0050] Reset and Continuous Operation Stage: After the single-segment forging sawing operation is completed, cylinder 5 drives sawing machine 2 to move upward to reset, spring 27 of the lower pressing component gradually rebounds, and pressure plate 28 moves upward synchronously with sawing machine 2 to disengage from the workpiece; electric push rod 9 drives clamping block 10 to move in the opposite direction to release the clamping constraint on the forging; first motor 16 starts in the opposite direction and drives baffle 3 to reset to the initial position through the drive component, ready for the next forging feeding and pushing operation; this cycle is repeated to realize the fully automated, continuous and large-scale operation of forging sawing process.

[0051] In summary, this device organically integrates functions such as automatic feeding, stable clamping, cooling spraying, waste collection and recycling through the mechanical linkage and collaborative operation of various functional modules. It realizes automated, high-precision, high-efficiency and low-loss operation of the entire forging sawing process, and is suitable for large-scale and continuous forging processing production scenarios.
