Description

Technical Field

[0001] This utility model relates to the field of sawing technology, and in particular to a bidirectional cooperative cooling and chip removal mechanism for electric sawing machines. Background Technology

[0002] Electric sawing machines, especially modern CNC metal sawing machines based on the "workpiece fixed, saw head moving" architecture, have become key equipment for metal processing and blanking. They cut metal profiles, bars and other materials through the high-speed rotation of saw blades (such as circular saw blades and band saw blades). In this process, a large amount of cutting heat and metal chips are generated.

[0003] For example, patent number CN222078138U discloses an automatic feeding device for a saw. This solution includes a processing table, an L-shaped frame fixedly connected to the top side of the processing table, an electric telescopic rod fixedly connected to the top side of the L-shaped frame, a cutting blade assembly fixedly connected to the output shaft of the electric telescopic rod, a baffle fixedly connected to the top side of the processing table, and a transverse groove opened on the top side of the processing table. In this application, a spring is used to push the push block to the leftmost position, and then the material plate is placed on the processing table. At this time, the spring's rebound force causes the push block to contact the left side of the placed material plate, and continues to apply a pulling force to the material plate until the right side of the material plate contacts the baffle. At this time, when the electric telescopic rod drives the cutting blade assembly to perform cutting operations up and down, automatic feeding can be completed. Compared with manual feeding, it can effectively improve efficiency, save time, and reduce the limitations of use.

[0004] For example, patent number CN218657100U discloses a sawing machine in the field of machining. It includes a frame, a cutting table, and a saw blade. Two guide plates are symmetrically slidably connected to the cutting table along the saw blade. The length extension direction of the two guide plates is consistent with the cutting direction of the workpiece. Both ends of the two guide plates extend out of the table surface of the cutting table. Guide rollers are rotatably connected to the sides of the two guide plates that are close to each other. The cutting table is also provided with a driving assembly for driving the two guide plates to slide. This application reduces workpiece misalignment and improves cutting accuracy.

[0005] Regarding the above description, the applicant believes that the following problems exist: Although the existing technology has solved the guidance problem, the heat and sharp chips generated by high-speed cutting will accumulate on the worktable, guide rail and moving parts, which will not only seriously scratch the surface of the workpiece and affect the processing accuracy, but also accelerate the wear of the equipment, pose safety hazards and lead to a harsh working environment. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a bidirectional collaborative cooling and chip removal mechanism for electric sawing machines. It has the functions of bidirectional cooling of the cutting area, automatic cleaning of chips on the worktable and solid-liquid separation, which alleviates the problems of decreased processing accuracy, increased equipment wear, prominent safety hazards and harsh working environment caused by chip accumulation. It achieves the significant effects of efficient cooling and chip removal, improved processing quality, protection of equipment safety and improvement of working environment.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] A bidirectional collaborative cooling and chip removal mechanism for an electric saw includes a saw body, a cutter arm, a material table and a worktable, as well as a perforated filter plate, a chip removal mechanism and a shaftless spiral solid-liquid separation mechanism.

[0009] The perforated filter plate is laid on the workbench surface, and its surface height is lower than that of the material table. A waste trough is opened at the end of the perforated filter plate away from the material table, and an inclined unloading ramp is provided adjacent to the waste trough. A material box is provided at the end of the unloading ramp.

[0010] The debris removal mechanism includes a scraper, three limiting blocks, a push plate, and an electric push rod. The scraper is arranged parallel to one end of the elongated filter plate near the material platform, and its height is lower than that of the material platform. The limiting blocks are fixed below the scraper and slidably embedded in the elongated filter holes of the elongated filter plate. The push plate is fixedly connected to the limiting block located in the middle. The cylinder of the electric push rod is fixed below the material platform, and the free end of the push rod is fixedly connected to the push plate to drive the scraper to reciprocate along the elongated filter plate.

[0011] The shaftless spiral solid-liquid separation mechanism is located below the long-pore filter plate, and its inlet is connected to the waste chip trough.

[0012] In one optional embodiment, there are two cutter arms, each cutter arm is provided with a water pipe quick connector, and a flow channel is opened inside the cutter arm. One end of the flow channel is connected to the water pipe quick connector, and the other end is connected to two water spray nozzles opened on the cutter arm near both ends of the saw blade.

[0013] In one optional embodiment, the angle between the axis of the water nozzle and the horizontal plane is 15 to 45 degrees.

[0014] In one optional embodiment, the unloading ramp has an inclination angle of 30 to 60 degrees, and its slope surface is provided with a row of freely rotating rollers.

[0015] In one optional embodiment, the shaftless spiral solid-liquid separation mechanism includes a motor, shaftless spiral blades, and a conveying pipe. The conveying pipe is inclined and has a feed trough on its upper wall, which is connected to the waste chip trough. The motor is fixed to the lower end of the conveying pipe, and its output shaft extends into the conveying pipe and is connected to one end of the shaftless spiral blades. A plurality of water filter holes are provided on the lower half of the conveying pipe wall near the motor. A waste chip box is provided below the higher end of the conveying pipe.

[0016] In one optional embodiment, the interior of the feed trough has an inclined structure.

[0017] In one optional embodiment, the angle between the axis of the water nozzle and the horizontal plane is 15 to 45 degrees.

[0018] In one optional embodiment, a liquid collection tank is provided below the filter holes of the delivery pipe.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. By setting up a long-hole filter plate and a chip removal mechanism consisting of a scraper, a limiting block, a pusher plate, and an electric push rod, the mechanized and automatic scraping and collection of chips on the worktable surface is realized. This alleviates the problem of chips accumulating in the processing area, scratching the workpiece, affecting accuracy, and aggravating equipment wear. It keeps the processing area clean, ensures positioning accuracy, and significantly reduces the frequency and intensity of manual cleaning.

[0021] 2. By setting dual water spray nozzles on the blade arm and forming a bidirectional synergistic cooling module with the internal flow channel and water pipe quick connector, coolant is sprayed synchronously and evenly from both sides of the saw blade cut, which alleviates the problem of uneven heat dissipation of the saw blade and difficulty in effectively removing chips from the cut caused by traditional single-sided cooling. It significantly improves cooling and lubrication efficiency, effectively prevents chips from clogging the cut, thereby extending the saw blade life and improving the cutting surface quality.

[0022] 3. By setting up a shaftless spiral solid-liquid separation mechanism consisting of a motor, shaftless spiral blades, and a conveying pipe with water filter holes, the automatic conveying and separation of the mixture of chips and coolant is realized. This alleviates the problems of difficult recycling, environmental pollution, and coolant waste caused by chips carrying a large amount of coolant. It is conducive to realizing dry recycling of chips and recycling of coolant, saving costs and creating a clean and safe working environment.

[0023] 4. By setting up an inclined unloading ramp and an end material box, and working in conjunction with the chip removal mechanism, the cut workpieces are smoothly slid down and automatically collected with the assistance of the scraper. This alleviates the problems of low workpiece handling efficiency, easy collision and safety risks in the traditional method, and is conducive to achieving the continuity and efficiency of the production process.

[0033] The perforated filter plate 5 is laid on the workbench 4, and its height is lower than that of the material table 3. The perforated filter plate 5 has a waste trough 14 at one end away from the material table 3. An inclined unloading ramp 6 is provided adjacent to the waste trough 14. A material box 7 is provided at the end of the unloading ramp 6.

[0034] The debris removal mechanism includes a scraper 11, three limiting blocks 12, a push plate 13, and an electric push rod 10. The scraper 11 is arranged parallel to one end of the elongated filter plate 5 near the material platform 3, and its height is lower than that of the material platform 3. The limiting blocks 12 are fixed below the scraper 11 and slidably embedded in the elongated filter holes of the elongated filter plate 5. The push plate 13 is fixedly connected to the limiting block 12 located in the middle. The cylinder of the electric push rod 10 is fixed below the material platform 3, and the free end of its push rod is fixedly connected to the push plate 13 for driving the scraper 11 to reciprocate along the elongated filter plate 5.

[0035] The shaftless spiral solid-liquid separation mechanism is located below the long-pore filter plate 5, and its inlet is connected to the waste chip trough 14.

[0036] In a preferred embodiment of this utility model, there are two blade arms 2, each blade arm 2 is provided with a water pipe quick connector 8, and a flow channel is opened inside the blade arm 2. One end of the flow channel is connected to the water pipe quick connector 8, and the other end is connected to two water spray nozzles 9 opened on the blade arm 2 and located near both ends of the saw blade.

[0037] In a preferred embodiment of this invention, the angle between the axis of the water nozzle 9 and the horizontal plane is 15 to 45 degrees. This angle range ensures that the coolant is accurately sprayed onto the cutting point to achieve the best cooling and chip removal effect.

[0038] In a preferred embodiment of this utility model, the unloading ramp 6 has an inclination angle of 30 to 60 degrees, and its slope surface is provided with a row of freely rotating rollers. This structure facilitates the automatic sliding of the cut workpiece into the material box 7, reducing manual intervention.

[0039] In a preferred embodiment of this utility model, the shaftless spiral solid-liquid separation mechanism includes a motor 15, a shaftless spiral blade 16, and a conveying pipe 17. The conveying pipe 17 is inclined and has a feed trough 19 on its upper wall. The feed trough 19 is connected to the waste chip trough 14.

The mixture of chips and coolant generated by cutting falls onto the surface of the perforated filter plate 5. Some of the coolant seeps through the filter holes. After cutting is completed, the electric push rod 10 pushes the scraper 11 to move along the perforated filter plate 5 toward the unloading ramp 6, scraping the accumulated chips into the waste chip trough 14, and simultaneously pushing the cut workpiece to the unloading ramp 6 and sliding it into the material box 7. The chip mixture passing through the waste chip trough 14 enters the feed trough 19 and falls into the shaftless spiral solid-liquid separation mechanism. The motor 15 drives the shaftless spiral blades 16 to rotate, conveying the mixture forward and squeezing it through the water filter holes 18 to dehydrate it during the conveying process. The dehydrated dry chips are finally pushed into the waste chip box 21 for centralized collection, while the separated coolant flows into the liquid collection box 20 for recycling or recovery.
