Description

Technical Field

[0001] This invention belongs to the field of sawing technology, and in particular to a sawing device for processing metal parts for vehicles. Background Technology

[0002] Band saws are key pieces of equipment in the machining field used for cutting metal materials, and are widely used in industries such as automobile manufacturing, aerospace, and construction machinery. In the production of vehicle metal parts, band saws are mainly used for cutting or pre-forming raw materials such as pipes, bars, and sections to a fixed length, making them important process equipment for achieving mass production and high-precision manufacturing of parts. Common types of band saws include belt saws, circular saws, and bow saws, whose basic structure typically includes a base, frame, sawing mechanism, clamping device, and cooling system. With the development of industrial automation and intelligent manufacturing, band saws are continuously upgrading towards higher efficiency, higher precision, intelligence, and energy conservation and environmental protection.

[0003] However, existing sawing devices for machining vehicle metal parts still have many technical shortcomings in practical applications, making it difficult to meet the demands of modern high-efficiency and precision machining. In particular, the coolant supply method during sawing is generally quite crude, often employing direct spray cooling. The coolant pipes are directly sprayed onto the saw blade or the workpiece's cutting point. While this design seems simple and direct, it has fundamental flaws. Because the saw blade (especially band saw blades) forms a dynamic cutting surface during high-speed reciprocating motion, the kerf depth and width (usually only a few millimeters) between the blade and the workpiece are large. Under high-pressure spray, the coolant is in a mist or scattered state. Most droplets are "thrown out" by the high-speed saw blade or splashed onto other areas of the workpiece surface before entering the kerf. The proportion of coolant that actually penetrates into the kerf is extremely low. The coolant is prone to splashing and uneven coverage, failing to effectively penetrate deep into the kerf, resulting in poor heat dissipation in the area where the saw blade contacts the workpiece. Summary of the Invention

[0004] The purpose of this invention is to provide a sawing device for processing metal parts of vehicles, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sawing machine device for processing metal parts of vehicles, comprising:

[0006] The saw base provides a support platform for the processing of metal parts for vehicles;

[0007] The saw frame is mounted on the saw base;

[0008] The saw blade hub has two symmetrically arranged at both ends of the saw frame and is protected by a protective cover.

[0009] The saw conditioner is used in conjunction with the saw blade hub to support both ends of the saw conditioner and drive the saw conditioner to rotate.

[0010] The guide rail plate, mounted on the saw frame, provides a guiding path for the sawing conditions;

[0011] The first guide post and the second guide post together provide guidance support for the sawing conditions;

[0012] Clamping mechanism, used to clamp the parts to be processed;

[0013] The coolant pipe extends from the lower part of the second guide post and the nozzle end is located directly above the saw condition;

[0014] The sawing condition is provided with a cooling and heat-reducing component on a circumferential section between the second guide post and the workpiece to be processed, which guides the coolant sprayed from the coolant pipe to flow along the sawing direction of the sawing condition onto the workpiece.

[0015] In a preferred embodiment, a control box is located at the center of the front side of the saw frame, and different control knobs are provided on the outer wall of the control box. The control box is installed behind the guide rail plate.

[0016] In this preferred embodiment, the top ends of the first guide post and the second guide post are slidably mounted on the guide rail plate and are respectively locked by the first locking bolt knob.

[0017] In a preferred embodiment, the clamping mechanism is disposed between the saw base and the saw frame, and the clamping mechanism is driven by hydraulic or manual clamping and loosening actions.

[0018] In this preferred embodiment, both the bottom ends of the first guide post and the second guide post are provided with guide pre-tightening mechanisms, and the two guide pre-tightening mechanisms respectively operate under rolling friction clamping conditions at the bottom ends of the first guide post and the second guide post.

[0019] In a preferred embodiment, the bottom ends of the first guide post and the second guide post are provided with mounting grooves on opposite sides for installing the guide pre-tightening mechanism. Each guide pre-tightening mechanism includes a pre-tightening clamping wheel that is symmetrically rotated and installed in the mounting groove. Two adjacent pre-tightening clamping wheels roll to clamp the friction saw.

[0020] In a preferred embodiment, the cooling and heat dissipation assembly includes coolant guide shields mounted on both sides of the saw condition near the nozzle end of the coolant pipe. The gap between the two coolant guide shields and the outer wall of the saw condition is smaller than the thickness of the saw condition. Each coolant guide shield and one side of the outer wall of the saw condition enclose a guide chamber for coolant inflow and outflow. The coolant guide shield includes a liquid flow inlet end near the coolant pipe and a liquid flow outlet end near the workpiece to be processed. The chamber enclosed by the liquid flow inlet end and the saw condition is larger than the chamber enclosed by the liquid flow outlet end and the saw condition.

[0021] In this preferred embodiment, a lifting connecting plate is welded between the top ends of the two coolant guide shields, and a connecting rod is welded to the top end of the lifting connecting plate. Chip collection plates are provided on the top end of the connecting rod and the outer wall of the second guide column, so that the connecting rod is installed together with the second guide column by fixing bolts. Multiple spiral guide grooves are symmetrically opened on the inner wall of each coolant guide shield near the liquid outlet end to guide the coolant flow to the contact area between the saw blade and the workpiece.

[0022] In a preferred embodiment, the top surface of the saw base has a chip collection tray, and a standard measuring plate is longitudinally welded to the top edge of the chip collection tray. A lower infrared sensor is installed on the lower part of the inner wall of the standard measuring plate facing the sawing conditions, and an upper infrared sensor is installed on the upper part.

[0023] In a preferred embodiment, a lifting sleeve is fitted onto the top of the standard measuring plate. The upper infrared sensor is installed on the inner wall of the lifting sleeve. The lifting sleeve is locked onto the standard measuring plate by a second locking bolt knob. A module control box is fixed at the bottom of the standard measuring plate and on the outer wall of the chip collection tray. The module control box contains a receiver for receiving signals emitted from the lower and upper infrared sensors and a PLC for controlling the saw feed speed using these signals.

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

[0025] This sawing device for machining vehicle metal parts utilizes a cooling component located on the periphery of the sawing condition between the second guide post and the workpiece. This component guides the coolant sprayed from the coolant pipe along the sawing direction to the workpiece. Combined with a guide chamber formed between the coolant guide cover and the outer wall of the sawing condition, with a gap smaller than the saw blade thickness, the coolant enters at the inlet end, is accelerated by pressure within the gradually narrowing guide chamber, and finally flows out from the outlet end in a flat shape against the outer wall of the sawing condition. This achieves precise and efficient coolant delivery to the sawing area. This design overcomes the problems of traditional sawing where direct coolant spraying leads to splashing, uneven coverage, and difficulty in penetrating the kerf. It allows the coolant to form a stable liquid film along the saw blade's movement direction, fully wetting the contact surface between the saw teeth and the workpiece, significantly improving heat dissipation efficiency. This effectively prevents saw blade annealing, accelerated wear, and "built-up edge" on the workpiece caused by localized high temperatures. Compared to existing technologies, this design extends saw blade life, improves sawing surface quality, and reduces downtime for maintenance.

[0026] By setting a pre-tensioning mechanism at the bottom of the first and second guide posts, and symmetrically rotating and installing pre-tensioning clamping wheels within their mounting grooves, the two pre-tensioning clamping wheels roll and clamp the friction saw from opposite sides, achieving dynamic stability support and tension control for the saw blade during operation. This structure effectively suppresses lateral vibration and sway of the saw blade caused by cutting force fluctuations during high-speed reciprocating or feeding, improving the straightness and stability of the sawing path. Compared with existing technologies that rely solely on end hub support and lack effective constraint in the middle of the saw blade, this solution significantly reduces vibration noise and kerf deviation during sawing, achieving the beneficial effects of improving processing accuracy, reducing the risk of saw blade fatigue fracture, and ensuring continuous and stable operation.

[0035] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0036] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this invention, and are explained here together.

[0037] This embodiment provides, for example Figures 1 to 5 The sawing device shown includes: a sawing base 1, a sawing frame 2, a saw blade hub 3, a sawing frame 4, a protective cover 5, a guide rail 7, a first guide post 8, and a second guide post 9.

[0038] In this embodiment, the saw base 1 serves as a support platform for processing vehicle metal parts; the saw frame 2 is mounted on the saw base 1; two saw blade hubs 3 are symmetrically positioned at both ends of the saw frame 2 and protected by a protective cover 5; the saw condition 4 works in conjunction with the saw blade hubs 3 to support both ends of the saw condition 4 and drive the saw condition 4 to rotate; the guide rail plate 7 is mounted on the saw frame 2 to provide a guide path for the saw condition 4; the first guide post 8 and the second guide post 9 together provide guidance support for the saw condition 4; the clamping mechanism 11 is used to clamp the workpiece 10 to be processed; the coolant pipe 21 extends from the lower part of the second guide post 9 and the nozzle end is located directly above the saw condition 4; a section of the saw condition 4 located between the second guide post 9 and the workpiece 10 is provided with a circumferential section for guiding the coolant sprayed from the coolant pipe 21 to flow along the sawing direction of the saw condition 4 to the cooling and heat dissipation components on the workpiece 10 to be processed.

[0039] In this embodiment, a control box 6 is located at the center of the front side of the saw frame 2. Different control knobs are provided on the outer wall of the control box 6. The control box 6 is installed behind the guide rail plate 7. The front side of the saw base 1 has a chip collection pool 16.

[0040] In this embodiment, the top ends of the first guide post 8 and the second guide post 9 are slidably mounted on the guide rail plate 7, and are respectively locked by the first locking bolt knob 19.

[0041] In this embodiment, the clamping mechanism 11 is disposed between the saw base 1 and the saw frame 2. The clamping mechanism 11 is driven by hydraulic or manual clamping and loosening actions. The clamping mechanism 11 includes two clamping plates 17 symmetrically arranged for clamping the workpiece 10 to be processed. One clamping plate 17 is fixed, and the other clamping plate 17 is pushed or pulled by a hydraulic push-pull rod or driven by rotating a lead screw through a handwheel 18, so that the two clamping plates 17 clamp the workpiece 10 to be processed.

[0042] In this embodiment, both the bottom ends of the first guide post 8 and the second guide post 9 are provided with guide pre-tightening mechanisms 12. The two guide pre-tightening mechanisms 12 respectively roll and rub at the bottom ends of the first guide post 8 and the second guide post 9 to clamp the operation of the saw condition 4. At the same time, through the back-to-back clamping and pulling of the first guide post 8, the second guide post 9 and the two guide pre-tightening mechanisms 12, the saw condition 4 between the first guide post 8 and the second guide post 9 can saw the parts to be processed 10.

[0043] In this embodiment, the bottom ends of the first guide post 8 and the second guide post 9 are provided with mounting grooves for mounting the guide pre-tightening mechanism 12. Each guide pre-tightening mechanism 12 includes a pre-tightening clamping wheel 24 that is symmetrically rotated and installed in the mounting groove. Two adjacent pre-tightening clamping wheels 24 roll and clamp the friction saw condition 4.

[0044] In this embodiment, the cooling and heat dissipation assembly includes coolant guide shields 22 mounted on both sides of the saw condition 4 near the nozzle end of the coolant pipe 21. The gap between the two coolant guide shields 22 and the outer wall of the saw condition 4 is smaller than the thickness of the saw condition 4. Each coolant guide shield 22 and one side of the outer wall of the saw condition 4 enclose a guide chamber 25 for coolant to flow in and out. The coolant guide shield 22 includes a liquid flow inlet end 26 near the coolant pipe 21 and a liquid flow outlet end 27 near the workpiece 10 to be processed. The chamber enclosed by the liquid flow inlet end 26 and the saw condition 4 is larger than the chamber enclosed by the liquid flow outlet end 27 and the saw condition 4. The coolant in the coolant pipe 21 is sprayed from the nozzle end and first enters the liquid flow inlet end 26. Since the guide chamber 25 is designed to gradually narrow, the coolant flows out from the liquid flow outlet end 27 in a flat shape. This flat shape can fit the outer wall of the saw condition 4, so that the water flows along the outer wall of the saw condition 4 and the sawing direction into the sawing area of ​​the workpiece 10 being sawed by the saw condition 4. This not only allows the coolant to effectively enter the sawing area and prevents the sawing area of ​​the workpiece 10 from overheating and forming a chip edge, but also washes away metal chips by the water flow that fits the outer wall of the saw condition 4 and the inner wall of the sawing area of ​​the workpiece 10, preventing chips from accumulating in the sawing area.

[0045] In this embodiment, a lifting plate 23 is welded between the top ends of the two coolant guide covers 22. A connecting rod 15 is welded to the top end of the lifting plate 23. Chip collection plates 14 are provided on the top end of the connecting rod 15 and the outer wall of the second guide post 9, so that the connecting rod 15 is installed together with the second guide post 9 by fixing bolts 20. Multiple spiral guide grooves 28 are symmetrically provided on the inner wall of each coolant guide cover 22 near the liquid outlet end 27 to guide the coolant to the contact area between the saw blade and the workpiece. By setting multiple spiral guide grooves 28 on the inner wall of the coolant guide cover 22 and cooperating with the flat water flow, the coolant can continue to be guided along the spiral path to the contact front edge between the saw teeth and the workpiece after flowing out of the liquid outlet end 27, realizing the function of dynamic tracking of the sawing point by the coolant. This design enhances the penetration and chip removal capabilities of the coolant, effectively flushing away metal chips in the saw kerf and preventing chip accumulation that could cause secondary scratches or blockages. Compared with existing technologies where the coolant is easily thrown off by the high-speed saw blade and chip removal is not smooth, this design achieves the beneficial effects of improving the processing environment, increasing chip removal efficiency, and ensuring sawing continuity.

[0046] In this embodiment, the top surface of the saw base 1 has a chip collection plate 14. A standard measuring plate 13 is longitudinally welded to the top edge of the chip collection plate 14. A lower infrared sensor 32 is installed on the lower part of the inner wall of the standard measuring plate 13 facing the saw condition 4, and an upper infrared sensor 33 is installed on the upper part. The lower infrared sensor 32 is used to detect the distance between the bottom saw teeth of the saw condition 4 and the bottom of the workpiece 10 to be processed. Once the distance between the saw teeth and the bottom of the workpiece 10 to be processed is equal to or less than a preset distance value, the feed speed of the saw condition 4 is slowed down to prevent fatigue fracture of the saw condition 4. The upper infrared sensor 33 detects when the saw teeth of the saw condition 4 cut into the workpiece 10 to be processed, and controls the feed speed of the saw condition 4 to slow down to prevent large impact at the moment of cutting and easy tooth breakage. This causes the feed rate of the saw teeth in saw condition 4 to slow down when they cut into the workpiece 10 and to the other side of the workpiece 10, while the feed rate can be fast when sawing the middle section of the workpiece 10. This not only speeds up sawing and prevents the saw from jamming, but also allows for the rapid introduction of coolant and the rapid removal of metal chips.

[0047] In this embodiment, a lifting sleeve 30 is fitted onto the top of the standard measuring plate 13. An upper infrared sensor 33 is installed on the inner wall of the lifting sleeve 30. The lifting sleeve 30 is locked onto the standard measuring plate 13 by a second locking bolt knob 31, allowing the height of the upper infrared sensor 33 to be adjusted by raising and lowering the lifting sleeve 30, thus meeting the needs of different parts 10 to be processed. A module control box 29 is fixed at the bottom of the standard measuring plate 13 and on the outer wall of the chip collection tray 14. The module control box 29 contains a receiver for receiving signals emitted from the lower infrared sensor 32 and the upper infrared sensor 33, and a PLC for controlling the feed speed of the saw condition 4 using these signals. By setting the upper infrared sensor 33 and the lower infrared sensor 32 on the standard measuring plate 13 and linking them with the PLC control system in the module control box 29, the intelligent feed speed control function for the saw condition 4 cutting in and cutting out stages is realized. Specifically, the upper infrared sensor 33 detects the displacement change of the saw teeth at the moment of initial entry into the workpiece, triggering the PLC to slow down the feed speed and avoid tooth breakage caused by impact load; the lower infrared sensor 32 detects the distance of the saw teeth when they approach the bottom of the workpiece, and reduces the feed speed in advance to prevent the saw blade from bending or breaking due to lack of support. This intelligent control mechanism realizes an adaptive feed strategy of "slow entry - fast mid-section cutting - deceleration exit". Compared with the existing technology of fixed feed speed or reliance on manual experience adjustment, it achieves comprehensive technical effects of optimizing cutting parameters, improving sawing efficiency, reducing saw blade wear, and ensuring operational safety.

[0048] Working principle

[0049] This sawing device for processing metal parts of vehicles uses a clamping mechanism 11 to firmly clamp the parts to be processed 10 (such as shock absorber linkages of motorcycles, solid round steel). The clamping mechanism 11 includes two clamping plates 17, one of which is fixed, and the other can be driven by a hydraulic push-pull rod or handwheel 18 to adjust the clamping force, ensuring that the parts to be processed 10 remain stable. The operator starts the sawing device through the control knob on the control box 6, ensuring that all mechanical parts operate normally. The control box 6 is located in the middle of the front side of the sawing frame 2, which is convenient for the operator to monitor and adjust various parameters. The positions of the first guide post 8 and the second guide post 9 are adjusted so that their top ends slide on the guide rail plate 7 and are locked by the first locking bolt knob 19 to ensure the stability of the sawing condition 4 during operation. The guide pre-tightening mechanism 12 is located at the bottom of the first guide post 8 and the second guide post 9, and clamps the sawing condition 4 through rolling friction to ensure the accuracy of the sawing process.

[0050] The coolant pipe 21 extends from the lower part of the second guide post 9, with the nozzle precisely positioned directly above the sawing condition 4. This position ensures that the coolant can be directly sprayed onto the sawing area of ​​the sawing condition 4, thereby achieving a highly efficient cooling effect. Two coolant guide shields 22 are respectively mounted on both sides of the sawing condition 4, with the gap between them and the outer wall of the sawing condition 4 being smaller than the thickness of the sawing condition 4. This design ensures that the coolant can be effectively guided to the sawing area while preventing coolant overflow. Each coolant guide shield 22 and one side of the outer wall of the sawing condition 4 enclose a guide chamber 25, which is used for the inflow and outflow of coolant.

[0051] The guide chamber 25 consists of a liquid inlet end 26 and a liquid outlet end 27. The liquid inlet end 26 is close to the nozzle end of the coolant pipe 21, while the liquid outlet end 27 is close to the workpiece 10 to be processed. The size of the chamber enclosed by the liquid inlet end 26 and the saw condition 4 is larger than the size of the chamber enclosed by the liquid outlet end 27 and the saw condition 4. This gradually decreasing design causes the coolant to enter from the liquid inlet end 26 and flow into the guide chamber 25. Finally, when it flows out from the liquid outlet end 27, it forms a flat water flow. The flat water flow can better conform to the outer wall of the saw condition 4 and flow into the sawing area of ​​the workpiece 10 to be processed along the sawing direction, effectively preventing the sawing area from overheating. The water flow also washes away metal chips, preventing chips from accumulating in the sawing area. On the inner wall of each coolant guide cover 22 near the liquid outlet end 27, multiple spiral guide grooves 28 are symmetrically opened. These spiral guide grooves 28 further guide the coolant flow to the contact area between the saw blade and the workpiece, enhancing the cooling effect and helping to remove chips. The saw blade hub 3 is activated, causing the saw condition 4 to rotate and align with the workpiece 10 along the path provided by the guide plate 7 to begin sawing. Coolant is sprayed onto the saw condition 4 through the coolant pipe 21, flowing into the sawing area in the sawing direction to maintain the cooling effect of the sawing area.

[0052] A lower infrared sensor 32 and an upper infrared sensor 33 are installed on the lower part of the inner wall of the standard measuring plate 13 facing the saw condition 4. These two sensors work together to monitor the status of the saw condition 4 in real time. The upper infrared sensor 33 is used to detect the state of the saw teeth of the saw condition 4 when they cut into the workpiece 10. When the saw teeth begin to cut into the workpiece 10, the upper infrared sensor 33 will detect the change in state. In order to prevent excessive impact at the moment of cutting and tooth breakage, the PLC control system will slow down the feed speed of the saw condition 4 to ensure smooth cutting. The lower infrared sensor 32 is mainly used to detect the distance between the bottom saw teeth of the saw condition 4 and the bottom of the workpiece 10. When the saw teeth approach the bottom of the workpiece 10, the lower infrared sensor 32 will detect the change in distance. Once the distance between the saw teeth and the bottom of the workpiece 10 is equal to or less than the preset distance value, the PLC control system in the module control box 29 will automatically reduce the feed speed of the saw condition 4 to prevent the saw condition 4 from fatigue fracture due to excessive stress.

[0053] The module control box 29 is fixed to the bottom of the standard measuring plate 13 and located on the outer wall of the chip collection tray 14. It contains a receiver and a PLC controller. The receiver receives signals from the lower infrared sensor 32 and the upper infrared sensor 33, and the PLC controller adjusts the feed speed of the saw condition 4 based on these signals. In this way, the feed speed of the saw teeth in saw condition 4 slows down when cutting into the workpiece 10 and to the other side of the workpiece 10, and the feed speed is fast when sawing the middle section of the workpiece 10. This not only increases the sawing speed and prevents jamming, but also allows for rapid intake of coolant and rapid removal of metal chips.

[0054] A lifting sleeve 30 is fitted on the top of the standard measuring plate 13, and an upper infrared sensor 33 is installed on the inner wall of the lifting sleeve 30. The lifting sleeve 30 can be adjusted by locking it to the standard measuring plate 13 with the second locking bolt knob 31, thereby adjusting the position of the upper infrared sensor 33 to accommodate parts 10 of different sizes to be processed.
