Description

Technical Field

[0001] This invention relates to the field of battery pack frame sawing equipment, and in particular to a double-head high-strength sawing machine for battery pack frames. Background Technology

[0002] Currently, replacing high-strength aluminum alloys with steel in the manufacture of battery frames for new energy vehicles is a growing trend. However, conventional steel has many drawbacks, the most significant being its high processing difficulty. While conventional aluminum alloys can be produced using a one-piece die-casting process, steel cannot. Furthermore, to ensure the structural strength of the frame, martensitic steel with a strength of 1100 MPa or higher is required. Conventional sawing equipment can only cut materials with a strength of around 300 MPa. The processing difficulty of the two is vastly different. During sawing, the high strength of the material causes the saw head to generate severe resistance, significantly increasing equipment vibration. This vibration leads to unstable saw blade operation and a tendency for the blade to break. To address these technical issues, reasonable improvements to the sawing machine are necessary. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a double-head high-strength sawing machine for battery pack frame, which has the characteristics of reducing the vibration of equipment and mold during processing, improving processing efficiency, ensuring stable operation of equipment, avoiding saw blade breakage, and improving processing efficiency.

[0004] The technical solution adopted by this invention to solve its technical problem is as follows: A double-head high-strength sawing machine for battery pack frames is provided, including a machine base, an overall protective cover, and a central window. The overall protective cover is installed at the edge of the upper surface of the machine base. A central window is provided in the center of the front side of the overall protective cover. Two central sliding doors are symmetrically installed and movable at the central window. A mold mounting platform is installed on the front of the upper end of the machine base. An impact-resistant mold is installed on the upper surface of the mold mounting platform. A transverse translation platform is symmetrically installed in the center of the upper end of the machine base. A rotating arm platform is rotatably mounted on the moving platform. A saw blade mounting platform is mounted on the rotating arm platform. The saw blade mounting platform moves along the rotating arm platform. A sawing head is rotatably mounted on the front end of the saw blade mounting platform. The anti-impact mold includes a clamping base, an elastic anti-impact rod, and a central support frame. There are two clamping bases, which are respectively mounted on two mold mounting platforms. Two elastic anti-impact rods are installed side by side between the two clamping bases. A central support frame is installed between the elastic anti-impact rods. A central top rod is lifted and lowered on the central support frame.

[0005] This technical solution uses two clamping bases and an elastic anti-impact rod connecting them. The two clamping bases ensure the clamping and fixing of both ends of the battery pack frame strip, while the elastic anti-impact rod buffers sudden impacts. When the saw blade applies sawing force, the steel structure is suddenly disrupted, breaking the force balance. The impact force directly contacts the frame strip, generating internal stress. This stress is transmitted to the two clamping bases, which then guide the stress to the elastic anti-impact rod. The elastic anti-impact rod deforms appropriately to absorb the stress and then recovers its original shape under its own elasticity, ensuring that the clamping bases do not vibrate violently, preventing saw blade breakage and ensuring stable equipment operation. Additionally, the lifting and installing central top rod supports the lower middle part of the frame strip, providing vertical support and improving the clamping firmness of the anti-impact mold.

[0006] When clamping and positioning, the clamping base holds both ends of the frame strip, and the middle top rod moves upward to abut against the lower side of the middle of the frame strip, so that the middle of the frame strip is subjected to upward stress, while the two ends of the frame strip are clamped and are subjected to downward stress. The frame strip is fixed at three points, so that the frame strip can be fixed in the vertical direction.

[0007] As a supplement to this technical solution, the anti-impact mold further includes a hydraulic cylinder mounting base, a clamping hydraulic cylinder, and a clamping block. The hydraulic cylinder mounting base is installed on the front of the upper end face of the clamping base, and the clamping block is installed on the rear of the upper end face of the clamping base. The clamping hydraulic cylinder is installed on the front side of the hydraulic cylinder mounting base. An oil circuit conversion module is installed at the front end of the middle support frame. The oil circuit conversion module is connected to the clamping hydraulic cylinder through an oil circuit pipe. The main shaft of the clamping hydraulic cylinder passes through the hydraulic cylinder mounting base and is connected to a moving block located at the front of the upper end face of the clamping base. Two guide posts passing through the hydraulic cylinder mounting base are symmetrically installed on the front side of the moving block. Connecting bolts are installed on both the left and right ends of the clamping base.

[0008] In this technical solution, a moving block and a clamping block are used to clamp and fix the front and rear sides of the product. At the same time, an oil circuit adapter module is installed to facilitate the transmission of hydraulic pressure to the clamping cylinder. The clamping cylinder is installed to push the moving block so that the moving block can clamp. Guide columns are installed to facilitate the smooth and stable operation of the moving block.

[0009] As a supplement to this technical solution, the upper end face and rear of the clamping base are provided with a transverse mounting groove. The cylinder mounting base and the clamping block are provided with mounting protrusions that are embedded in the transverse mounting grooves. The upper end face of the clamping block is provided with a clamping opening. Several clamping opening pressure plates are installed on the moving block and the clamping block. A first buffer groove is provided in the middle of the lower end face of the clamping base. Two second buffer grooves aligned with the first buffer groove are symmetrically arranged on the upper end face of the mold mounting platform. A strip-shaped buffer pad is installed between the first buffer groove and the second buffer groove. The clamping block and the moving block are provided with saw cuts.

[0010] In this technical solution, clamping openings are provided to clamp and fix both ends of the product. A transverse mounting groove is installed to facilitate the installation of the hydraulic cylinder mounting base and clamping block. Mounting protrusions are provided on the hydraulic cylinder mounting base and clamping block to facilitate stability and ensure that sudden impacts generated during sawing are effectively guided from the frame strips to the clamping base. Simultaneously, a clamping opening pressure plate is installed to press down on the frame strips, fixing the upper side of the frame strips. First and second buffer grooves are installed to facilitate the installation of strip-shaped buffer pads, which are used to absorb impacts between the mold mounting platform and the anti-impact mold. A sawing opening is provided to facilitate the entry of the saw blade for sawing the frame strips.

[0011] As a supplement to this technical solution, the lateral translation stage includes a first lateral support plate and a platform body. A strip-shaped ceramic plate is embedded in the front middle of the first lateral support plate. A first brake caliper, which is connected to the strip-shaped ceramic plate, is symmetrically installed on the lower end face of the platform body. The rear side of the platform body is arc-shaped, and a first arc-shaped ceramic plate is embedded in the rear side of the platform body. A second brake caliper, corresponding to the first arc-shaped ceramic plate, is installed on the lower end face of the swing arm platform. The saw blade mounting table includes a vertical mounting frame and a turntable structure. A second arc-shaped ceramic plate is provided on the upper edge of the turntable structure. A third brake caliper, corresponding to the second arc-shaped ceramic plate, is installed on the vertical mounting frame.

[0012] In this technical solution, a primary fixation of the platform body is achieved by installing strip-shaped ceramic plates and a first brake caliper. A secondary fixation of the rotating arm platform is achieved by installing a first arc-shaped ceramic plate and a second brake caliper. A tertiary fixation of the turntable structure is achieved by installing a second arc-shaped ceramic plate and a third brake caliper. Through these three sets of fixing devices, the misalignment of various parts of the equipment during operation is prevented, thus ensuring the operational accuracy of the equipment.

[0013] In this technical solution, a bottom brake line mounting bracket is installed on the lower end face of the transverse translation stage. The bottom brake line mounting bracket is used to fix the brake line, which facilitates the connection between the brake line and the first brake caliper. At the same time, the movement of the transverse translation stage can synchronously drive the bottom brake line mounting bracket, so that the brake line can move synchronously, thereby avoiding the brake line from getting tangled.

[0014] As a supplement to this technical solution, the transverse translation table includes two transverse slide rails, which are installed side by side in the lower part of the machine. A first slide block covering the transverse slide rail is installed on the lower end face of the transverse translation table. Two longitudinal slide rails are installed side by side on the upper end face of the rotating arm platform. Several second slide blocks covering the longitudinal slide rails are installed on the saw blade mounting platform. One side of both the transverse and longitudinal slide rails is provided with a mounting groove parallel to the transverse or longitudinal slide rail. Several elastic buffer blocks are evenly installed in the mounting groove at intervals, and the elastic buffer blocks abut against the transverse or longitudinal slide rails.

[0015] In this technical solution, mounting grooves are set on one side of the transverse and longitudinal slide rails to facilitate the installation of elastic buffer blocks. The elastic buffer blocks are used to buffer the vibration. When the entire equipment vibrates due to a sudden impact, the elastic buffer blocks will absorb the vibration and ensure that the transverse translation table and saw blade mounting table can still operate stably and smoothly.

[0016] As a supplement to this technical solution, the transverse translation stage includes a platform body, a first transverse support plate, and a second transverse support plate. The first and second transverse support plates are installed side by side inside the machine tool. A longitudinal base plate is installed between the two ends of the first and second transverse support plates, and a middle base plate is installed between the middle of the first and second transverse support plates. A transverse transmission motor with its main shaft facing the middle of the machine tool is installed on the upper surface of the longitudinal base plate. A lead screw mounting seat is installed on the middle base plate, and a transverse lead screw is installed between the transverse transmission motor and the lead screw mounting seat. An internal thread transmission block with the transverse lead screw is installed on the lower surface of the platform body.

[0017] In this technical solution, the transverse drive motor can drive the transverse lead screw, which, through the external thread structure, can drive the internal thread transmission block to move in the left and right directions, thereby driving the platform body to move.

[0018] As a supplement to this technical solution, a stabilizing seat is installed at the front end of the upper end of the platform body near the middle of the machine tool. A third slide with its opening facing upward is installed on the stabilizing seat. A stabilizing slide rail is installed laterally on the rear part of the lower end face of the mold mounting table. A mounting groove parallel to the stabilizing slide rail is provided on one side. Several elastic buffer blocks are evenly installed in the mounting groove at intervals. The elastic buffer blocks abut against the stabilizing slide rail.

[0019] In this technical solution, an additional stabilizing slide rail is added to ensure stable left and right movement of the platform body. The stabilizing seat and the third slide are connected to the stabilizing slide rail, so that the platform body also has a horizontally moving sliding structure on top. This allows the platform body to be subject to dual constraints from above and below when it moves, ensuring stable sliding of the platform body.

[0020] As a supplement to this technical solution, a transmission shaft is installed on the front of the upper end of the transverse translation stage, and the upper end of the transmission shaft is connected to the lower front end of the rotating arm platform. A first arc-shaped rack is installed on the rear side of the transverse translation stage, and a rotating arm drive motor with its main shaft facing downward is installed on one side of the rear end of the rotating arm platform. A first gear that meshes with the first arc-shaped rack is installed on the main shaft of the rotating arm drive motor. Rotating arm limit blocks are installed on the left and right sides of the upper end face of the transverse translation stage.

[0021] In this technical solution, a swing arm drive motor is used to drive the first gear, and a transmission shaft is installed to facilitate the swing arm platform to rotate around the transmission shaft. The first gear drives the first arc-shaped rack, and the first arc-shaped rack is used to adjust the rotation angle of the swing arm platform.

[0022] As a supplement to this technical solution, a saw blade feed motor with its spindle facing forward is installed on the rear of the upper end face of the swing arm platform. The spindle of the saw blade feed motor is connected to the feed screw. The saw blade mounting table includes a sawing base, a vertical mounting frame, and a turntable structure. The sawing base is installed on the swing arm platform. A transmission block connected to the feed screw is installed on the lower end face of the swing arm platform. Foldable protective covers that connect to the front and rear ends of the swing arm platform are installed at both the front and rear ends of the sawing base. A vertical mounting frame is installed on the sawing base. A turntable structure is rotatably installed on the front upper end of the vertical mounting frame. The turntable structure includes a connecting bushing and a limiting device. The turntable and the ring are described. A limiting ring is installed in the middle of the vertical mounting frame. A mating sleeve for inserting the limiting ring is installed at the center of the rear end face of the turntable body. A second arc-shaped rack is embedded in the lower side of the turntable body. A turntable drive motor with its main shaft facing forward is installed on the vertical mounting frame. A second gear meshing with the second arc-shaped rack is installed on the main shaft of the turntable drive motor. A limiting pin is installed on the upper rear side of the turntable structure. A limiting clamp is installed on the upper front side of the vertical mounting frame. The limiting clamp has an arc hole structure that matches the limiting pin. A sawing head is installed at the center of the front end face of the turntable structure.

[0023] In this technical solution, a folding protective cover is installed to prevent waste chips and cutting fluid from entering the rotary arm platform, ensuring that the interior is not affected by the external working environment. At the same time, by installing a second arc-shaped rack and a second gear, the rotary table drive motor can adjust the rotation angle of the rotary table body. Additionally, limit clamps and limit pins are installed to limit the rotation angle of the rotary table body.

[0024] As a supplement to this technical solution, a buffer frame is installed at the lower inner end of the middle sliding door, two sets of sliding door limit frames corresponding to the two buffer frames are symmetrically installed at the front end of the machine, a front stabilizing slide rail corresponding to the buffer frame is installed on the front side of the mold mounting platform, gas springs are installed at both ends of the buffer frame, and a slider structure that covers the front stabilizing slide rail is installed on the rear side of the buffer frame.

[0025] In this technical solution, a front stabilizing slide rail is set to ensure that the middle sliding door and the mold mounting platform form a front constraint. This ensures that the middle sliding door moves smoothly while also providing front support for the mold mounting platform when it is impacted, thus further improving the stability of the mold mounting platform.

[0026] As a supplement to this technical solution, the lower inner side of the overall protective cover is equipped with an inclined structure with the lower end tilting towards the middle of the machine tool. A power distribution box is installed in the middle of the rear of the machine tool. Several drawer-type filter boxes are installed at the lower rear of the machine tool. The drawer-type filter boxes are arranged in two groups at the lower rear of the machine tool. A cutting fluid return tank is provided below each group of drawer-type filter boxes. A connecting nozzle is installed at the end of the cutting fluid return tank near the power distribution box. A liquid level balance pipe is installed between the two connecting nozzles.

[0027] As a supplement to this technical solution, a guide slope with its rear end tilting downwards and extending to the front end of the drawer-type filter box is installed in the middle of the machine.

[0028] Beneficial Effects: This invention relates to a double-headed high-strength sawing machine for battery pack frames. By setting two clamping bases and an elastic anti-impact rod connecting the two clamping bases, the two clamping bases ensure the clamping and fixing of both ends of the battery pack frame strips. Simultaneously, the elastic anti-impact rod between the two bases buffers sudden impacts. When the saw blade is applying sawing force, the sudden disruption of the steel structure breaks the force balance, and the impact force directly contacts the frame strips. The frame strips generate internal stress from the impact, which is transmitted to the two clamping bases. The two clamping bases then guide the stress to the elastic anti-impact rod, which deforms appropriately to absorb the stress and then recovers its original shape under its own elasticity. This ensures that the clamping bases do not vibrate violently, preventing saw blade breakage and ensuring stable equipment operation. It features reduced vibration of the equipment and molds during processing, improved processing efficiency, stable equipment operation, prevention of saw blade breakage, and increased processing efficiency.

[0052] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0053] Embodiments of the present invention relate to a double-head high-strength sawing machine for battery pack frames, such as... Figures 1-6As shown, the machine includes a machine base 1, an integrated protective cover 2, and a central window 3.

A mold mounting platform 6 is installed on the front of the upper end of the machine base 1. An impact-resistant mold 7 is installed on the upper surface of the mold mounting platform 6. A transverse translation platform 8 is symmetrically installed in the middle of the upper end of the machine base 1.

The impact force will directly contact the frame strip, and the frame strip will generate internal stress under the impact. The stress will be transmitted to the two clamping bases 13, and the two clamping bases 13 will then guide the stress to the elastic anti-impact rod 21. The elastic anti-impact rod 21 will deform appropriately to absorb the stress, and then recover under its own elasticity, ensuring that the clamping bases 13 will not vibrate violently, avoiding saw blade breakage, and ensuring stable operation of the equipment. At the same time, in this technical solution, the middle top rod 25 installed by lifting is used to support the lower middle part of the frame strip and to provide vertical support for the frame strip, thereby improving the clamping firmness of the anti-impact mold 7.

The clamping cylinder 17 is installed to push the moving block 16 so that the moving block 16 can clamp. A guide post is installed to facilitate the smooth and stable operation of the moving block 16.

[0058] As a supplement to this technical solution, the upper front and rear of the clamping base 13 are provided with a transverse mounting groove 14. The cylinder mounting base 15 and the clamping block 18 are provided with mounting protrusions that are embedded in the transverse mounting groove 14. The upper front of the clamping block 18 is provided with a clamping opening 26. Several clamping opening pressure plates 20 are installed on both the moving block 16 and the clamping block 18. The lower end face of the clamping base 13 is provided with a first buffer groove 28. Two second buffer grooves 84 aligned with the first buffer groove 28 are symmetrically arranged on the upper end face of the mold mounting platform 6. A strip-shaped buffer pad 29 is installed between the first buffer groove 28 and the second buffer groove 84. The clamping block 18 and the moving block 16 are provided with saw cuts 19.

[0059] In this technical solution, clamping openings 26 are provided to clamp and fix both ends of the product. A transverse mounting groove 14 is installed to facilitate the installation of the hydraulic cylinder mounting base 15 and the clamping block 18. The hydraulic cylinder mounting base 15 and the clamping block 18 are provided with mounting protrusions to facilitate the stabilization of the hydraulic cylinder mounting base 15 and the clamping block 18. During sawing, the sudden impact generated can be well guided from the frame strip to the clamping base 13. At the same time, the clamping opening pressure plate 20 is installed to press down the frame strip and fix the upper side of the frame strip. The first buffer groove 28 and the second buffer groove 84 are installed to facilitate the installation of the strip-shaped buffer pad 29. The strip-shaped buffer pad 29 is installed to absorb the impact generated between the mold mounting table 6 and the anti-impact mold 7.

[0060] like Figures 7-10 As shown, as a supplement to this technical solution, the transverse translation stage 8 includes a first transverse support plate 30 and a platform body 37. A strip-shaped ceramic piece 40 is embedded in the front side of the middle part of the first transverse support plate 30.

The saw blade mounting table 10 includes a vertical mounting frame 62 and a turntable structure 63. A second arc-shaped ceramic piece 65 is provided on the upper edge of the turntable structure 63. A third brake caliper 67 corresponding to the second arc-shaped ceramic piece 65 is installed on the vertical mounting frame 62.

[0061] In this technical solution, the platform body 37 is firstly fixed by installing strip-shaped ceramic plates 40 and first brake calipers 50, the rotating arm platform 9 is secondarily fixed by installing first arc-shaped ceramic plates 52 and second brake calipers 85, and the turntable structure 63 is thirdly fixed by installing second arc-shaped ceramic plates 65 and third brake calipers 67. With these three sets of fixing devices, the misalignment of various parts of the equipment during operation is avoided, and the operating accuracy of the equipment can be guaranteed.

[0062] In this technical solution, a bottom brake line mounting bracket 57 is installed on the lower end face of the transverse translation stage 8. The bottom brake line mounting bracket 57 is used to fix the brake line, which facilitates the connection between the brake line and the first brake caliper 50. At the same time, the movement of the transverse translation stage 8 can synchronously drive the bottom brake line mounting bracket 57, so that the brake line can move synchronously, thereby avoiding the brake line from getting tangled.

[0063] As a supplement to this technical solution, the transverse translation stage 8 includes two transverse slide rails 35, which are installed side by side in the lower part of the machine base 1. A first slide block 48 covering the transverse slide rail 35 is installed on the lower end surface of the transverse translation stage 8. Two longitudinal slide rails 53 are installed side by side on the upper end surface of the rotating arm platform 9. Several second slide blocks 68 covering the longitudinal slide rails 53 are installed on the saw blade mounting table 10. One side of the transverse slide rail 35 and the longitudinal slide rail 53 is provided with a mounting groove 42 parallel to the transverse slide rail 35 or the longitudinal slide rail 53.

[0064] In this technical solution, an installation groove 42 is provided on one side of the transverse slide rail 35 and the longitudinal slide rail 53 to facilitate the installation of the elastic buffer block 43. The elastic buffer block 43 is used as a buffer. When the entire equipment vibrates due to a sudden impact, the elastic buffer block 43 will absorb the vibration and ensure that the transverse translation table 8 and the saw blade mounting table 10 can still operate stably and smoothly.

[0065] As a supplement to this technical solution, the transverse translation stage 8 includes a platform body 37, a first transverse support plate 30, and a second transverse support plate 34.

[0068] In this technical solution, in order to stabilize the left and right movement of the platform body 37, an additional stabilizing slide rail 44 is added. The stabilizing seat 45 and the third slide 46 are connected to the stabilizing slide rail 44, so that the platform body 37 also has a horizontally moving sliding structure on top. This allows the platform body 37 to be subject to double constraints from above and below when it moves, ensuring that the platform body 37 slides stably.

[0069] like Figures 11-15 As shown, as a supplement to this technical solution, a transmission shaft 47 is installed on the front of the upper end of the transverse translation stage 8.

[0070] In this technical solution, the rotating arm drive motor 55 is used to drive the first gear 58, and the transmission shaft 47 is installed to facilitate the rotation of the rotating arm platform 9 around the transmission shaft 47.

[0071] like Figures 16-18As shown, as a supplement to this technical solution, a saw blade feed motor 54 with its spindle facing forward is installed on the rear of the upper end face of the rotary arm platform 9. The spindle of the saw blade feed motor 54 is connected to the feed screw 56. The saw blade mounting table 10 includes a sawing base 60, a vertical mounting frame 62, and a turntable structure 63.

[0072] In this technical solution, a folding protective cover 61 is installed to prevent waste chips and cutting fluid from entering the rotary arm platform 9, ensuring that the interior is not affected by the external working environment. At the same time, by installing a second arc-shaped rack 70 and a second gear 71, the turntable drive motor 69 can adjust the rotation angle of the turntable body 64. Meanwhile, by installing a limit clamp 74 and a limit pin 75, the rotation angle of the turntable body 64 is limited.

[0073] like Figure 2 and Figure 22 As shown, as a supplement to this technical solution, a buffer frame 81 is installed at the lower inner end of the middle sliding door 4, two sets of sliding door limiting frames 83 corresponding to the two buffer frames 81 are symmetrically installed at the front end of the machine base 1, a front stabilizing slide rail 82 corresponding to the buffer frame 81 is installed on the front side of the mold mounting platform 6, gas springs 49 are installed at both ends of the buffer frame 81, and a slider structure 66 covering the front stabilizing slide rail 82 is installed on the rear side of the buffer frame 81.

[0074] In this technical solution, by setting a front stabilizing slide rail 82, the middle sliding door 4 and the mold mounting platform 6 form a front constraint, thereby ensuring that the middle sliding door 4 moves smoothly and that the mold mounting platform 6 has a front support when it is impacted, which further improves the stability of the mold mounting platform 6.

Example

[0077] When sawing high-strength martensitic steel, the process differs from conventional sawing of aluminum alloys. Conventional sawing equipment uses cutting force to peel and sever the material. However, martensitic steel has a martensitic structure throughout its surface and interior, resulting in a dense and strong structure. The cutting force alone cannot peel the material. Therefore, when cutting martensitic steel, a feed force is first applied to create friction between the saw blade and the steel. This friction heats the cutting area, disrupting the internal crystal structure and facilitating the cutting process. Cutting, however, in actual sawing, will generate sudden impacts. The source of the impact is: when the equipment is feeding and sawing, the saw blade structure and the material are in contact, the martensite crystal is not destroyed, the saw blade structure is applying compressive stress to the steel, and at the same time the equipment is still feeding, the stress between the saw blade structure and the material will continue to increase. When the martensite crystal is destroyed in an instant, the stress between the saw blade structure and the material is instantly unbalanced. The saw blade structure impacts the material, which will cause the saw blade structure to impact the mold and the equipment, thus causing the mold and the equipment to vibrate, which will lead to the problem of saw blade breakage.

[0078] The various structures in this technical solution can absorb this unbalanced stress, avoid high-amplitude vibration, prevent chipping, and ensure smooth operation of the equipment.

[0079] When sawing, first select an impact-resistant mold 7 with an appropriate sawing vent 19 according to the frame strip. Install the impact-resistant mold 7 on the mold mounting table 6 using connecting bolts 27. After completion, install the frame strip in the clamping port 26. Then, start the clamping cylinder 17. The main shaft of the clamping cylinder 17 pushes the moving block 16. Then, the clamping block 18 and the moving block 16 will clamp the front and rear sides of the end of the frame strip. At the same time, the clamping port pressure plate 20 will press the front and rear edges of the upper side of the frame strip to form upper positioning. Then, adjust the height of the middle push rod 25 so that the upper end of the middle push rod 25 can abut against the lower side of the middle of the frame strip to form lower positioning.

[0080] After completion, adjust the rotation angle and offset angle of the saw head 11 according to the structure of the saw cut 19. First, it is necessary to control the left and right movement distance of the two saw heads 11. First, start the two horizontal drive motors 36. The horizontal drive motors 36 are used to control the position of the two horizontal translation stages 8. The two horizontal translation stages 8 operate independently. According to the actual needs, control the rotation of the two horizontal lead screws 38. The horizontal lead screws 38 can drive the internal thread transmission block 39. The internal thread transmission block 39 can drive the platform body 37 to move laterally. After the adjustment is completed, start the first brake caliper 50. The first brake caliper 50 clamps the strip ceramic piece 40 to fix the horizontal translation stage 8.

[0081] Next, the rotation adjustment of the swing arm platform 9 is carried out. According to the required angle, the swing arm drive motor 55 is started. The swing arm drive motor 55 drives the first gear 58, the first gear 58 drives the first arc rack 51, and the first arc rack 51 rotates the swing arm platform 9 so that the rotation angle of the swing arm platform 9 is the same as the required angle. Then, the second brake caliper 85 is activated. The second brake caliper 85 clamps the first arc ceramic plate 52 to fix the swing arm platform 9.

[0082] After completion, the rotation angle of the saw head 11 is adjusted. According to the prior requirements, the rotation angle of the saw head 11 is input, and then the turntable drive motor 69 is started. The turntable drive motor 69 drives the second gear 71, and the second gear 71 drives the second arc-shaped rack 70 and the turntable structure 63 to rotate. After completion, the third brake caliper 67 is started. The third brake caliper 67 clamps the second arc-shaped ceramic piece 65 to fix the turntable structure 63.

[0083] After completing the above adjustments, the sawing action is performed. The saw blade feed motor 54 is started, which drives the feed screw 56. The feed screw 56 pushes the transmission block, which drives the sawing base 60. The sawing base 60 pushes the sawing head 11, which enters the sawing opening 19 to perform the sawing action on the frame strip.

[0084] After sawing is completed, the saw blade feed motor 54 reverses and resets. At the same time, after replacing the new frame strip, a second processing can be carried out to form a mass production method.
