Description

Technical Field

[0001] This invention relates to the field of circular die-cutting machine technology, specifically to an arc-shaped template processing device. Background Technology

[0002] When producing corrugated cardboard boxes, rotary die-cutting machines require selecting the appropriate rotary die-cutting plate based on the thickness, precision requirements, and die-cutting quantity of the corrugated cardboard. In the construction industry, cylindrical templates are needed for formwork support when casting circular columns. Currently, curved templates are often used as the processing base for rotary die-cutting plates and cylindrical templates. The existing operating method for processing curved templates according to design dimensions is as follows: the curved template is tied and fixed to a roller shaft using straps, the roller shaft drives the curved template to rotate, and simultaneously, cutting saw blades on both sides of the roller shaft cut the curved template to the specified dimensions at both ends.

[0003] The above cutting process usually requires two workers to work together: one to adjust the position of the curved template and the other to secure it with straps. After both ends are cut, the straps must be removed before the cut curved template can be taken off and the next curved template can be processed.

[0004] However, this fixed method is cumbersome to operate, resulting in low processing efficiency; at the same time, it requires two people to work together, which leads to high labor costs. Summary of the Invention

[0005] The purpose of this invention is to provide an arc-shaped template processing device, which can improve the end face cutting efficiency of arc-shaped templates, thereby improving the processing efficiency of arc-shaped templates, while reducing the number of operators and thus reducing labor costs.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: an arc-shaped template processing device, including a whole machine support frame, an end cutting mechanism, and an arc-shaped template positioning mechanism. Two sets of end cutting mechanisms are arranged on the upper part of the whole machine support frame, which are arranged opposite to each other. Each set of end cutting mechanisms includes a second support frame, a first driving mechanism, a third support frame, a second driving mechanism, and a first cutting saw blade. The second support frame is arranged on the upper crossbeam of the whole machine support frame. The first driving mechanism and the third support frame are arranged on the lower part of the corresponding second support frame. The output end of the first driving mechanism is connected to the third support frame and is used to drive the third support frame to perform circumferential motion. The second driving mechanism is arranged on the third support frame. The first cutting saw blade is arranged on the output shaft of the second driving mechanism, and the rotation axis of the first cutting saw blade is parallel to the axis of the arc-shaped template. The arc-shaped template positioning mechanism is arranged on the lower crossbeam of the whole machine support frame and is located between the two sets of end cutting mechanisms.

[0007] Preferably, the processing device further includes a trimming mechanism, which includes a first linear reciprocating drive mechanism, a fourth support frame, and trimming components. The first linear reciprocating drive mechanism is mounted on the machine support frame and located below the lower crossbeam. The fourth support frame is slidably mounted on the machine support frame and connected to the output end of the first linear reciprocating drive mechanism. Two sets of trimming components are symmetrically arranged on the upper front and rear sides of the fourth support frame. Each set of trimming components includes a fifth support frame, a third drive mechanism, and a second cutting saw blade. The fifth support frame is mounted on the fourth support frame, the third drive mechanism is mounted on the fifth support frame, and the second cutting saw blade is mounted on the output shaft of the third drive mechanism, with its rotation axis perpendicular to the axis of the arc-shaped template.

[0008] Furthermore, a second linear reciprocating drive mechanism is provided on the upper right side of the machine support frame. The second support frame, located on the right side of the upper crossbeam, is slidably mounted on the upper crossbeam and connected to the output end of the second linear reciprocating drive mechanism.

[0009] Furthermore, the first drive mechanism includes a first servo motor, a first reducer, a first coupling, and a first transmission shaft. The output end of the first servo motor is connected to the first coupling through the first reducer, and the output end of the first coupling is connected to the first transmission shaft. The other end of the first transmission shaft is fixedly connected to the rotation center of the third support frame. The first reducer and the first transmission shaft are both mounted on the corresponding second support frame.

[0010] Furthermore, a third linear reciprocating drive mechanism is provided on the third support frame. The second drive mechanism includes a second servo motor, and the output end of the third linear reciprocating drive mechanism is fixedly connected to the housing of the second servo motor.

[0011] Furthermore, a fourth linear reciprocating drive mechanism is provided on the fourth support frame. The output end of the fourth linear reciprocating drive mechanism is connected to the two fifth support frames to synchronously drive the two sets of cutting edge components to move in opposite or opposite directions in a direction perpendicular to the axis of the arc-shaped template. The third drive mechanism includes a third servo motor.

[0012] Furthermore, a protruding head cutting mechanism and an indented groove cutting mechanism are respectively provided on one side of each of the two fifth support frames.

[0013] Furthermore, a line laser is provided on both the upper left and right sides of the fifth support frame. The line laser is used to project a horizontal beam onto the side wall of the arc-shaped template. The lower edge of the beam of the line laser is flush with the lower edge of the second cutting saw blade.

[0014] Furthermore, the arc-shaped template positioning mechanism includes at least two clamping seats arranged at intervals along the length of the lower crossbeam. Each set of clamping seats includes a base and a support seat. The base is fixedly installed on the lower crossbeam and a top-pressing bolt is provided on the base. The bottom of the support seat is fixed to the base in the vertical direction by the top-pressing bolt. An arc-shaped support surface matching the outer diameter of the arc-shaped template is provided on the upper part of the support seat.

[0015] Furthermore, at least two sets of clamping assemblies are provided on the upper crossbeam at intervals along the length direction. Each set of clamping assemblies includes a clamping cylinder and a clamping frame. The clamping cylinder is fixedly installed upside down on the upper part of the upper crossbeam, and the telescopic rod of the clamping cylinder passes downward through the upper crossbeam and is fixedly connected to the upper end of the clamping frame. A Λ-shaped guide frame located on the side of the corresponding clamping cylinder is fixedly installed on the lower side of the upper crossbeam.

[0016] The beneficial effects of this invention are as follows: The invention has a simple structure and can be fully manufactured using existing machining processes; the arc-shaped template positioning mechanism enables rapid positioning and disassembly of the arc-shaped template, significantly shortening the single clamping time and thus improving processing efficiency; this invention allows for high-precision dimensional cutting of the arc-shaped template end face and simultaneous trimming of the sides, significantly reducing equipment footprint and process changeover time compared to traditional processes that require two separate machines for end face cutting and side trimming, while also avoiding cumulative positioning errors caused by multiple clamping operations; when cutting the arc-shaped template using this processing device, only one operator is needed, thereby reducing the labor cost of arc-shaped template production; the second linear reciprocating drive mechanism's lateral adjustment and positioning capability for the corresponding end cutting mechanism facilitates the implementation of two first cuts. The distance between saw blades is adjusted to accommodate the processing needs of curved templates of different lengths. The third linear reciprocating drive mechanism adjusts the positioning of the first cutting saw blade, allowing for adjustment of its cutting radius in the vertical plane, thus adapting to the processing needs of curved templates with different outer diameters. A fourth linear reciprocating drive mechanism adjusts the spacing between the two second cutting saw blades, also adapting to the processing needs of curved templates with different outer diameters. A linear laser beam assists operators in correcting the circumferential angle of the curved template, ensuring the accuracy of the second cutting saw blades in trimming the sides of the template. The combined use of a dust extraction hood and a negative pressure generator enables real-time collection and directional flow of sawdust and dust generated during the cutting process, thereby improving the cleanliness of the working environment. Simultaneously cutting both sides of the curved template, a convex chuck cutting mechanism and a concave groove cutting mechanism simultaneously process the concave grooves and convex chucks on the sides, significantly improving the processing efficiency of the curved template.

Detailed Implementation

[0019] The following will describe specific embodiments and appendices. Figure 1-15 The technical solutions in the embodiments of the present invention are clearly and completely described below. Obviously, the described embodiments are only some preferred embodiments of the present invention, and not all embodiments. Those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] This invention provides an arc-shaped template processing device (such as...) Figure 1 and 2As shown, the machine includes a support frame 1, an end cutting mechanism 2, and an arc-shaped template positioning mechanism 3. The support frame 1 provides structural support and rigid load-bearing for the entire processing device. In practical applications, it can be welded from steel pipes and plates. The end cutting mechanism 2 is used to cut the end face of the arc-shaped template 6. Two sets of end cutting mechanisms 2 are arranged on the upper part of the support frame 1, which are arranged in opposite directions. By using the two sets of end cutting mechanisms 2, the arc-shaped template 6 located between them can be cut to a fixed length, thereby satisfying the corresponding... The arc-shaped template length requirement dictates that each set of end cutting mechanisms 2 includes a second support frame 21, a first drive mechanism 22, a third support frame 23, a second drive mechanism 24, and a first cutting saw blade 25. The second support frame 21 is mounted on the upper crossbeam 11 of the machine support frame 1. The first drive mechanism 22 and the third support frame 23 are mounted below the corresponding second support frame 21. The output end of the first drive mechanism 22 is connected to the third support frame 23 to drive the third support frame 23 in circular motion. The second drive mechanism 24 is mounted on the third support frame 23. The first cutting saw blade 25 is mounted on the output shaft of the second drive mechanism 24, and the rotation axis of the first cutting saw blade 25 is parallel to the axis of the arc-shaped template. In actual application, the third support frame 23 moves in a circular motion under the drive of the first drive mechanism 22, and the first cutting saw blade 25 moves in a circular motion under the drive of the second drive mechanism 24. When the rotation center axis of the first cutting saw blade 25 does not coincide with the circular motion center axis of the third support frame 23, the first cutting saw blade 25 revolves around the circular motion center axis of the third support frame 23. This results in the first cutting saw blade 25 cutting within a ring-shaped area. When the end of the arc-shaped template 6 is located within this ring-shaped area, the first cutting saw blade 25 can be used to precisely cut its end face, thus achieving fixed-length cutting of the arc-shaped template 6. The arc-shaped template positioning mechanism 3 is mounted on the lower crossbeam 12 of the machine support frame 1 and is located between the two sets of end cutting mechanisms 2. In practical applications, the arc-shaped template positioning mechanism 3 is used to clamp and position the circumferential angle and axial position of the arc-shaped template 6 so that precise cutting can be completed using the end cutting mechanism 2. In practical applications, a single person can quickly position the arc-shaped template material using the arc-shaped template positioning mechanism 3, and disassembly is convenient after processing, thereby improving the end cutting efficiency of the arc-shaped template.

[0021] Based on the above embodiments, to further improve the overall processing efficiency of the arc template, the processing device further includes a trimming mechanism 4. In practical applications, the trimming mechanism 4 is used to simultaneously trim the edges of both sides of the arc template 6. Specifically, the trimming mechanism 4 includes a first linear reciprocating drive mechanism 41, a fourth support frame 42, and a trimming assembly 43. The first linear reciprocating drive mechanism 41 is mounted on the machine support frame 1 and located below the lower crossbeam 12. The fourth support frame 42 is slidably mounted on the machine support frame 1 and connected to the output end of the first linear reciprocating drive mechanism 41. In practical applications, the first linear reciprocating drive mechanism 41 can drive the fourth support frame 42 to slide and position horizontally. The bottom of the fourth support frame 42 is provided with a linear guide slider, and a matching linear guide is provided on the machine support frame 1. The linear guide slider is used to slide and position the fourth support frame 42. The blocks work together to achieve smooth sliding of the fourth support frame 42. The first linear reciprocating drive mechanism 41 can be a servo motor with a ball screw pair, or a pneumatic or hydraulic drive element, or a synchronous belt drive mechanism or a gear and rack drive structure. In combination with the actual application, the synchronous belt drive structure is preferred in this embodiment because it has a long conveying stroke and low cost. Specifically, synchronous pulleys are symmetrically installed on both sides of the lower part of the support frame 1. The synchronous pulleys are rotated and supported by the support shaft. The motor power assembly is connected to the corresponding support shaft to drive the synchronous belt 411 to circulate. In this specific embodiment, the motor power assembly includes a servo motor and a reducer. The reducer is connected to the corresponding support shaft by belt drive. The servo motor outputs stable torque through the reducer to drive the synchronous belt 411 to run smoothly, thereby driving the fourth support frame 42 to move precisely back and forth along the linear guide rail.Furthermore, two sets of cutting components 43 are symmetrically arranged on the upper front and rear sides of the fourth support frame 42. In actual application, one set of cutting components 43 corresponds to one edge of the arc-shaped template 6. By moving the fourth support frame 42, the two sets of cutting components 43 simultaneously trim the edges of the arc-shaped template 6 at equal intervals. Each set of cutting components 43 includes a fifth support frame 431, a third drive mechanism 432, and a second cutting saw blade 433. The fifth support frame 431 is arranged on the fourth support frame 42. In this specific embodiment, the fifth support frame 431 is vertically installed on the fourth support frame 42, and the third drive mechanism 432 is arranged on the fifth support frame 42. On the support frame 431, the second cutting saw blade 433 is mounted on the output shaft of the third drive mechanism 432, and its rotation axis is perpendicular to the axis of the arc template. In the actual cutting process, the arc template is placed horizontally, which in turn causes the second cutting saw blade 433 to be placed horizontally. In this specific embodiment, the third drive mechanism 432 includes a third servo motor, and the output shaft of the third servo motor is directly fixedly connected to the second cutting saw blade 433. By using the precise speed control of the third servo motor, the second cutting saw blade 433 is ensured to rotate stably at a constant linear speed, thereby ensuring the consistency and smoothness of the cutting of the two sides of the arc template 6. In practical applications, to facilitate the synchronous trimming and cutting of the sides of the arc-shaped templates 6 with different outer diameters by the two sets of cutting components 43, a fourth linear reciprocating drive mechanism 44 is provided on the fourth support frame 42. The output end of the fourth linear reciprocating drive mechanism 44 is connected to two fifth support frames 431, which is used to synchronously drive the two sets of cutting components 43 to move in opposite or opposite directions in a straight line along a direction perpendicular to the axis of the arc-shaped template. That is, the distance between the two sets of fifth support frames 431 is adjusted by the fourth linear reciprocating drive mechanism 44, thereby realizing the adjustment of the distance between the two second cutting saw blades 433, so as to accurately adapt to the arc-shaped templates 6 with different radii. In this specific embodiment, a fourth linear reciprocating drive mechanism 44 is installed on the fourth support frame 42. A high-precision linear guide rail is used, with a matching linear guide rail slider installed at the bottom of the fifth support frame 431. The linear guide rail slider slides smoothly along the linear guide rail, ensuring that the fifth support frame 431 has no offset or shaking during the spacing adjustment process. Simultaneously, the fourth linear reciprocating drive mechanism 44 is a ball screw drive structure. The screw connecting the two fifth support frames 431 is a bidirectional screw 441 with forward and reverse threads. The bidirectional screw 441 is rotatably mounted on the fourth support frame 42, and one end is connected to a corresponding servo motor. The servo motor synchronously drives the two fifth support frames 431 to move equidistantly towards or away from each other along the linear guide rail via the bidirectional screw 441, thereby achieving precise control of the distance between the two saw blades.

[0022] Based on the above embodiments, to facilitate the processing and manufacturing of arc-shaped templates of different lengths using two sets of end cutting mechanisms 2, a second linear reciprocating drive mechanism 13 is provided on the upper right side of the machine support frame 1. The second support frame 21 located on the right side of the upper crossbeam 11 is slidably mounted on the upper crossbeam 11 and connected to the output end of the second linear reciprocating drive mechanism 13. Specifically, a rectangular groove is provided on the upper part of the second support frame 21, and linear guide sliders are provided on the upper inner sidewall and the front and rear sidewalls of the rectangular groove. Matching linear guides are provided at corresponding positions on the upper crossbeam 11. The linear guide sliders slide smoothly along the linear guides of the upper crossbeam 11, ensuring that the second support frame 21 maintains high rigidity and zero sway during longitudinal movement. The second linear reciprocating drive mechanism 13 can be a servo motor with a ball screw pair, or it can be a pneumatic or hydraulic drive element. Alternatively, it can be a synchronous belt drive mechanism or a gear and rack drive structure. Considering the actual application, to improve the positioning stability and repeatability of the second support frame 21, this embodiment preferably uses a servo motor driven ball screw pair structure. The output shaft of the servo motor is coaxially connected to one end of the first screw 131, and the other end of the first screw 131 is supported on the end of the upper crossbeam 11 via a bearing seat. The ball screw nut pair is fixed to the upper outer side of the rectangular groove of the second support frame 21, thereby ensuring that the second support frame 21 can accurately translate along the axial direction of the upper crossbeam 11. Utilizing the self-locking capability of the servo motor, the second support frame 21 can reliably maintain its current position after position adjustment or in a power-off state, eliminating displacement deviations caused by gravity or vibration. Simultaneously, to enhance the overall system response speed and dynamic accuracy, the servo motor uses a high-resolution encoder closed-loop feedback to correct motion errors in real time.

[0023] Based on the above embodiments, a specific implementation of one embodiment of the first driving mechanism 22 is as follows: The first driving mechanism 22 includes a first servo motor 221, a first reducer 222, a first coupling 223, and a first transmission shaft 224. The servo motor, reducer, coupling, and transmission shaft are all commonly used and known mature technology products in the mechanical field, so the specific structure and working principle of each component will not be described in detail here. The output end of the first servo motor 221 is connected to the first coupling 223 through the first reducer 222, and the output end of the first coupling 223 is connected to the first transmission shaft 224. Specifically, a first mounting base 211 is fixedly provided on the lower outer side of the corresponding second support frame 21, and the first reducer 222 is fixed on the first mounting base 211. Its input shaft is connected to the first servo motor 224. The output shaft of motor 221 is coaxially connected, and the output shaft is rigidly connected to the first transmission shaft 224 through the first coupling 223. The first transmission shaft 224 is rotatably mounted in the bearing seat at the lower part of the second support frame 21, and the first transmission shaft 224 can only rotate and cannot move axially. The first servo motor 221 is used to realize the precise rotation control of the first transmission shaft 224. The other end of the first transmission shaft 224 is fixedly connected to the rotation center of the third support frame 23. The rotation of the third support frame 23 is realized by driving the first transmission shaft 224. The rotation of the third support frame 23 around the center of the first transmission shaft 224 realizes the first cutting saw blade 25 to revolve around the central axis of the first transmission shaft 224. During the revolution of the first cutting saw blade 25, the end of the arc template 6 can be cut.

[0024] Based on the above embodiments, to facilitate the adjustment of the revolution radius of the first cutting saw blade 25, so as to achieve precise adaptation and cutting of the ends of arc-shaped templates 6 with different diameters, a third linear reciprocating drive mechanism 26 is set on the third support frame 23. The second drive mechanism 24 includes a second servo motor. The output end of the third linear reciprocating drive mechanism 26 is fixedly connected to the housing of the second servo motor. The third linear reciprocating drive mechanism 26 can drive the second servo motor to perform linear reciprocating adjustment and positioning along the length range of the third support frame 23, thereby realizing the adjustment and positioning of the position of the first cutting saw blade 25, and thus dynamically changing the revolution radius. The third linear reciprocating drive mechanism 26 can be a servo motor with a ball screw pair, or a pneumatic or hydraulic drive element, or a synchronous belt drive mechanism or a gear and rack drive structure. In combination with the actual application, in order to improve the positioning stability and repeatability of the second servo motor, this embodiment... For example, a preferred servo motor-driven ball screw pair structure is adopted. The output shaft of the servo motor is coaxially connected to one end of the ball screw. The ball screw is rotatably mounted on the third support frame 23. The ball screw nut pair is fixed to the first movable seat 261 slidably mounted on the third support frame 23. A linear guide slider is provided at the bottom of the first movable seat 261, and a corresponding linear guide is provided on the third support frame 23, forming a high-rigidity and high-precision guide support. The first movable seat 261 moves synchronously with the ball screw nut pair, thereby ensuring the smooth and precise displacement of the second servo motor, which in turn drives the first cutting saw blade 25 to move stably. Utilizing the self-locking capability of the servo motor, the first movable seat 261 can reliably maintain its current position after the position adjustment is completed or in the power-off state, eliminating displacement deviations caused by gravity or vibration. At the same time, in order to enhance the overall response speed and dynamic accuracy of the system, the servo motor adopts a high-resolution encoder closed-loop feedback to correct motion errors in real time.

[0025] Based on the above embodiments, this embodiment provides two specific implementation methods for electrically connecting the third linear reciprocating drive mechanism 26 and the second servo motor to an external power supply. The first implementation method is as follows: the first drive shaft 224 is a solid shaft. When the first drive shaft 224 drives the second servo motor to rotate continuously 360°, to prevent the power supply cable and signal cable of the second servo motor from tangling, a through-hole wire slip ring 225 is provided on one side of the lower part of the second support frame 21. The through-hole guide slip ring is used to electrically connect the external power supply cable and signal cable to the second servo motor and the third linear reciprocating drive mechanism 26. The rotor of the through-hole wire slip ring 225 is fixedly connected to the first drive shaft 224, and the stator of the through-hole conductive slip ring 225 is connected to the second support frame 21, thereby achieving uninterrupted and stable transmission of power and signals during the continuous rotation of the first drive shaft 224. The second implementation method is as follows: the first drive shaft 224... A hollow shaft, the power lines and signal lines of the third linear reciprocating drive mechanism 26 and the second servo motor connected to the external power and signal sources are led out from the hollow first drive shaft 224 and then connected to the external power and signal sources. In this embodiment, the first coupling 223 is replaced with a pair of gear transmission groups. The gear transmission group includes two gears, one gear is fixed on the outer end of the first drive shaft 224, and the other is fixed on the output end of the first reducer 222. The two gears mesh and transmit power. At the same time, during use, the first drive shaft 224 only rotates 360 degrees in one revolution. That is, after the first drive shaft 224 completes one revolution, it is reset. After resetting, it rotates 360 degrees again as needed. Although the first drive shaft 224 has a certain torsional effect on the power and signal lines, the torsional effect is not significant with only one revolution. Thus, manufacturing costs can be saved while ensuring normal use.

[0026] Based on the above embodiments, when using the second cutting saw blade 433 to simultaneously and precisely cut the two sides of the arc template, in order to effectively prevent sawdust from splashing and interfering with the view and contaminating the equipment during the cutting process, a dust suction hood 434 is installed on the upper part of the second cutting saw blade 433. The opening side of the dust suction hood 434 faces the contact area between the second cutting saw blade 433 and the arc template. The dust suction hood 434 is connected to the external negative pressure dust collection system through a flexible hose. In order to facilitate the synchronous movement of the flexible hose during the lateral reciprocating movement of the fourth support frame 42, a vertical rod is fixedly installed on the upper part of the fourth support frame 42. The end of the flexible hose connected to the dust suction hood 434 is fixedly installed on the vertical rod. At the same time, a steel wire rope is installed on both sides of the upper part of the machine support frame 1. Several pulley groups are installed on the steel wire rope. The flexible hose is connected to the negative pressure dust collection system after passing through each pulley group. Then, by using the movement of the pulley groups on the steel wire rope, the orderly extension and contraction and tension adaptive adjustment of the flexible hose can be realized. Using negative pressure suction, wood chips and dust generated by high-speed rotation are instantly removed from the work area, ensuring a clean and controllable working environment. The negative pressure dust collection system can be an industrial-grade central vacuum unit or a stand-alone portable vacuum equipment in the existing technology field.

[0027] When processing cylindrical templates using this invention, to facilitate simultaneous processing of the upper convex head and inner recess on the side of the arc-shaped template while using the second cutting saw blade 433 to cut the side, an convex head cutting mechanism and an inner recess cutting mechanism are respectively provided on one side of each of the two fifth support frames 431. The convex head cutting mechanism includes a sixth support frame 81, a fourth servo motor 82, and an convex head cutting blade 83. The sixth support frame 81 is fixedly installed on one side of the fifth support frame 431, and the fourth servo motor 82 is detachably installed on the sixth support frame 81. When processing and manufacturing circular die-cutting plates using this invention, it is not necessary to simultaneously process the upper convex head and inner recess on the arc-shaped template. The protruding head is processed on the cut edge of the template, so the fourth servo motor 82, along with the protruding head cutting blade 83, can be removed from the sixth support frame 81 when processing the rotary die-cutting plate. The protruding head cutting blade 83 is detachably connected to the output shaft of the fourth servo motor 82. The protruding head cutting blade 83 includes a first annular body, and a plurality of first cutting seats 831 are fixedly and evenly spaced on the outer circumferential wall of the first annular body. A first cutting blade 832 is provided on the outer cutting side of the first cutting seat 831. An inner groove 8321 distributed along the radial direction of the first annular body is provided in the middle of the first cutting blade 832. The first cutting blade 832 rotates at high speed. As the material moves continuously along the axis of the arc-shaped template, the side of the arc-shaped template is continuously cut. During the cutting process, the inner groove 8321 cannot cut the material. After the cutting is completed, an outwardly protruding chuck is formed on the moving path of the inner groove 8321. The inner groove cutting mechanism includes a seventh support frame 91, a fifth servo motor 92, and an inner groove cutting blade 93. The seventh support frame 91 is fixedly set on one side of the fifth support frame 431, and the fifth servo motor 92 is detachably set on the seventh support frame 91. When using this invention to process and manufacture a circular die-cutting plate, it is not necessary to process the inner groove on the cut edge of the arc-shaped template. Therefore, when processing a circular die-cutting plate, it is not necessary to process the inner groove. The fifth servo motor 92, along with the recessed groove cutting blade 93, is removed from the seventh support frame 91. The recessed groove cutting blade 93 is detachably connected to the output shaft of the fifth servo motor 92. The recessed groove cutting blade 93 includes a second annular body. Several second cutting seats 931 are fixedly and evenly spaced on the outer circumferential wall of the second annular body. A second cutting blade 932 is located on the upper outer side of the second cutting seat 931. The second cutting blade 932 protrudes outward along the radial direction of the second annular body. While rotating at high speed, the outwardly protruding second cutting blade 932 continuously moves along the axial direction of the arc-shaped template, thus cutting a recessed groove on the side of the arc-shaped template. The convex clamping head is adapted to the recessed groove. When multiple cylindrical templates are spliced ​​sequentially, the convex clamping head is sequentially placed into the corresponding recessed groove, thereby realizing the splicing of multiple cylindrical templates and improving their splicing sealing.

[0028] Based on the above embodiments, a specific implementation of one embodiment of the arc-shaped template positioning mechanism 3 is as follows: The arc-shaped template positioning mechanism 3 includes at least two clamping seats arranged at intervals along the length direction of the lower crossbeam 12. In this specific embodiment, two clamping seats are provided along the length direction of the lower crossbeam 12. Each set of clamping seats includes a base 31 and a support seat 32. The base 31 is fixedly installed on the lower crossbeam 12, and a top-pressing bolt 311 is provided on the base 31. The bottom of the support seat 32 is fixed to the base 31 in the vertical direction by the top-pressing bolt 311. Specifically, the base 31 is composed of two vertical plates that are distributed opposite to each other on the left and right. Two top-pressing bolts 311 are provided on each vertical plate, and a limiting plate 312 is provided on the front and rear sides of the gap between the two vertical plates. The two limiting plates 312 facilitate the positioning of the bottom of the support base 32 on the base 31, thereby effectively ensuring the accuracy of the installation positioning of the support base 32 in the front-back direction on the base 31. An arc-shaped support surface matching the outer diameter of the arc template is provided on the upper part of the support base 32. In actual application, arc templates with different outer diameters need to be adapted to support bases 32 of different specifications so that the arc-shaped support surface of the support base 32 can be precisely fitted with the outer circumference of the arc template. The bottom structural features of support bases 32 of different specifications are the same so that they can be stably installed and fixed on the base 31. The two support bases 32 can be used to achieve horizontal support of the corresponding model of arc template 6, and at the same time, make the two upper sides of the arc template 6 within the cutting range of the two second cutting saws.

[0029] Based on the above embodiments, after the arc-shaped template 6 is manually placed on the two support seats 32, in order to facilitate the effective cutting of the sides of the arc-shaped template 6 by both second cutting saw blades 433, a line laser 7 is provided on the upper left and right sides of the fifth support frame 431. The line laser 7 is a common high-precision positioning auxiliary device in the existing technical field. Therefore, in this specific embodiment, the specific structure and working principle of the line laser 7 will not be described in detail. The line laser 7 is used to project a horizontal beam 74 onto the side wall of the arc-shaped template. The lower edge of the beam 74 of the line laser 7 is flush with the lower edge of the second cutting saw blade 433. The operator can intuitively judge the relative height relationship between the saw blade and the side of the arc-shaped template 6 by the projection position of the beam 74, thereby quickly adjusting the circumferential placement angle of the arc-shaped template 6 on the support seat 32 to ensure that the two Each of the second cutting saw blades 433 can effectively cut the side of the arc-shaped template 6. In this specific embodiment, a second mounting base 71 is provided on both sides of each dust collection hood 434. Each second mounting base 71 is provided with two first elongated holes 711, which are arranged vertically. A positioning threaded rod 72 is provided on the dust collection hood 434 and fitted into the first elongated holes 711. A locking nut for pressing the second mounting base 71 is fitted on the positioning threaded rod 72. By loosening the locking nut, the height of the second mounting base 71 can be adjusted. A mounting sleeve 73 is fixedly installed on the second mounting base 71. A corresponding line laser 7 is fitted inside the mounting sleeve 73. A radial adjustment bolt for locking the line laser 7 is provided on the side wall of the mounting sleeve 73. Tightening the radial adjustment bolt can securely fix the position of the laser. In actual operation, by adjusting the vertical position of the second mounting base 71, the vertical height of the linear laser 7 can be adjusted synchronously to ensure that the lower edge of the beam 74 is always precisely aligned with the lower edge of the second cutting saw blade 433.

[0030] Based on the above embodiments, to ensure that the arc-shaped template 6 remains stably fitted to the arc surface of the support base 32 during the cutting process, at least two sets of clamping components are provided on the upper crossbeam 11, spaced apart along the length direction. In this specific embodiment, two sets of clamping components are provided on the upper crossbeam 11. Each set of clamping components includes a clamping cylinder 51 and a clamping frame 52. The clamping cylinder 51 is inverted and fixedly installed on the upper part of the upper crossbeam 11, and the telescopic rod of the clamping cylinder 51 passes downward through the upper crossbeam 11 and is fixedly connected to the upper end of the clamping frame 52. By moving the telescopic rod of the clamping cylinder 51 up and down, the clamping frame 52 is driven to rise and fall synchronously, so that the lower end of the clamping frame 52 is tightly fitted to the inner arc surface of the arc-shaped template 6, thereby effectively preventing arcing during the cutting process. The curved template 6 may shift or warp; the clamping frame 52 has a ∩-shaped structure, and flexible silicone pads can be provided at the bottom of its two vertical rods to enhance the fit and friction with the inner wall of the curved template 6; in order to improve the clamping stability of the clamping frame 52 on the curved template 6, the clamping frame 52 is distributed along the radial direction of the curved template 6. In practical applications, to prevent the clamping frame 52 from deflecting excessively, a Λ-shaped guide frame 53 located on one side of the corresponding clamping cylinder 51 is fixedly installed on the lower side of the upper crossbeam 11. During the upward movement of the clamping frame 52, when the upper part of the clamping frame 52 enters the included angle area of ​​the Λ-shaped guide frame 53, the inclined surfaces on both sides of the Λ-shaped guide frame 53 form a guide limit with the outer side of the upper end of the clamping frame 52, forcing the clamping frame 52 to return to its initial placement state.

[0031] In practical applications, the PLC control system can be used to achieve automated cutting of the two ends and sides of the arc template. Specifically, the PLC controller of the PLC control system is electrically connected to the corresponding servo motors in the first linear reciprocating drive mechanism 41, the second linear reciprocating drive mechanism 13, the third linear reciprocating drive mechanism 26 and the fourth linear reciprocating drive mechanism 44. At the same time, the PLC control system is electrically connected to the second servo motor, the third servo motor and the clamping cylinder 51. The PLC controller is pre-set with automated cutting control modules for different models of arc templates.Before the initial cutting operation, the preset return control module in the PLC controller is used to ensure that each actuator is in its set return position. For example, the first cutting saw blade 25 is positioned at its maximum revolution radius, the distance between the two second cutting saw blades 433 is the maximum outer diameter arc template 6 cutting distance, the distance between the two sets of second support frames 21 is the longest arc template 6 cutting distance, and the fourth support frame 42 is located behind the corresponding second support frame 21. Then, the worker selects the corresponding support base 32 according to the model of the arc template and fixes the support base 32 on the base 31. After the support base 32 is clamped and positioned, the arc template to be processed is then placed... Plate 6 is placed stably on the arc surface of support base 32. Simultaneously, based on the reference line projected by the linear laser 7, the circumferential placement angle of the arc template 6 is finely adjusted so that a clear beam 74 can be seen on both sides of the arc template 6. After the initial positioning of the arc template 6 is completed, the PLC control system is activated, and the corresponding model of the automation control module is retrieved. According to the set program, the system first automatically adjusts the revolution radius of the first cutting saw blade 25, the distance between the two second cutting saw blades 433, and the distance between the two first cutting saw blades 25. After the above adjustments are completed, the clamping cylinder 51 is activated, and the clamping frame 52 moves down synchronously and fits against the inner arc surface of the arc template. Then, the edge cutting assembly 43 performs edge cutting. The end-cutting mechanism 2, located away from the edge-cutting component 43, performs end-cutting operations simultaneously. During this synchronization, it is crucial to ensure that the cutting action of the end-cutting component does not obstruct the normal operation of the edge-cutting component 43, and that the two are strictly staggered in space and time. Specifically, the edge-cutting component 43 only begins cutting the end region after the end-cutting mechanism 2 completes its end-cutting and returns to its initial cutting position, ensuring no interference in the cutting path. Simultaneously, when the edge-cutting component 43 leaves the cutting range of the adjacent end-cutting mechanism 2, the end-cutting mechanism 2 immediately initiates the corresponding end-cutting operation. After completing the corresponding end-cutting operation, the end-cutting mechanism... 2. Quickly reset: After the cutting edge assembly 43 completes the side cutting, it moves to the preset position to wait for the next cycle of cutting. After completing the cutting of one arc template 6, the clamping cylinder 51 retracts. Then, the processed arc template is manually removed, and a new arc template 6 of the same model is placed in it. After placement, the PLC controller is used to perform the next cutting process. In this cutting process, the cutting edge assembly 43 and the end cutting mechanism 2 away from the cutting edge assembly 43 are run first. Then, the end cutting mechanism 2 close to the cutting edge assembly 43 is started according to the set control logic. This process is repeated to achieve continuous processing of the same model of arc template. When it is necessary to change to the processing of different models of arc templates, the return position program is run first to make all the actuators in the return preset position. Then, the support seat 32 fixing mechanism is loosened, a support seat 32 adapted to the new model is replaced and relocked.

[0032] While cutting the ends and sides of the arc-shaped template, if it is also desired to simultaneously process the convex head and the concave groove, the fourth servo motor 82 and the fifth servo motor 92 are mounted on the corresponding brackets. At the same time, the PLC controller is electrically connected to the fourth servo motor 82 and the fifth servo motor 92. During the cutting process, the PLC controller synchronously starts the fourth servo motor 82 and the fifth servo motor 92, and the convex head cutting blade 83 and the concave groove cutting blade 93 are used to achieve the synchronous processing of the convex head and the concave groove.
