Description

Technical Field

[0001] The invention relates to the technical field of cutting devices, and in particular to a cutting device for elevator decorative sheet metal processing. Background Art

[0002] With the rapid advancement of urbanization and the rapid development of the real estate industry, the demand for elevators, as an indispensable transportation equipment in modern buildings, has shown a rapid growth trend. Elevators are not only required to be safe and reliable in terms of function, but also gradually pursue personalized and beautiful decoration to meet the needs of different users.

[0003] The patent with publication number CN110653311B discloses a steel plate cutting device and method, which performs preliminary extrusion on the steel plate through extrusion mechanism I and extrusion mechanism II, and starts clamping mechanism I and clamping mechanism II to further clamp the steel plate; starts the height motor to adjust the horizontal height of the adjustment mechanism, and starts the transverse motor to adjust the rotation center of the rotation mechanism; starts two cutting mechanisms, and the two cutting mechanisms extrude the plate; starts the rotating motor, and the rotating motor drives the two cutting mechanisms to rotate around the axis of the output shaft of the rotating motor as the center to twist the steel plate; double-sided cutting reduces the distance of single-sided tool cutting to ensure neat incisions.

[0032] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] Reference Figures 1 to 11As shown: A cutting device for elevator decorative sheet metal processing, including a rectangular mounting frame 1, a clamping mechanism 2, a connecting structure 3 and a cutting mechanism 4; the clamping mechanism 2 includes two clamping structures 21, the two clamping structures 21 are symmetrically arranged about the horizontal middle plane of the rectangular mounting frame 1, the clamping structure 21 includes a lifting shaft 211, one end of the lifting shaft 211 vertically extends into the interior of the rectangular mounting frame 1, and one end of the lifting shaft 211 is coaxially provided with a circular clamping disk 212; the connecting structure 3 has two, the two connecting structures 3 are connected to the two clamping structures 21, and the two connecting structures 3 are symmetrically arranged about the horizontal middle plane of the rectangular mounting frame 1, the connecting structure 3 includes a sleeve 31, a connecting arm 32 and a rotating mechanism 33, the sleeve 31 is sleeved on the lifting shaft 211 through a bearing, and the middle of the connecting arm 32 The part is fixedly connected to the sleeve 31, the rotating mechanism 33 is arranged on the lifting shaft 211, and the rotating mechanism 33 is transmission-connected to the sleeve 31, the rotating mechanism 33 includes a mounting plate 331, a rotating driver 332, a driving gear 333 and a driven gear 334, one end of the mounting plate 331 is fixedly connected to the lifting shaft 211, the rotating driver 332 is arranged on the other end of the mounting plate 331, the driving gear 333 is connected to the output end of the rotating driver 332, the driven gear 334 is coaxially arranged on the sleeve 31, and the driving gear 333 is meshed with the driven gear 334; the cutting mechanism 4 includes a clamping structure 41 and a cutting assembly 42, the clamping structure 41 has two, the two clamping structures 41 are respectively connected to the connecting arms 32 in the two connecting structures 3, and the cutting assembly 42 is installed on one of the clamping structures 41.

[0034] First, the decorative plate to be cut is placed between the two clamping structures 21. The two clamping structures 21 drive the circular clamping disks 212 to move toward each other through their respective lifting shafts 211 until the two circular clamping disks 212 are in close contact with the upper and lower surfaces of the decorative plate, respectively, to fix the decorative plate. Subsequently, the two rotating mechanisms 33 are started simultaneously. In each rotating mechanism 33, the rotating driver 332 drives the driving gear 333 to rotate. The driving gear 333 drives the sleeve 31 to rotate through the driven gear 334 that is closely meshed with it. The rotation of the sleeve 31 further drives the connecting arm 32 fixedly connected thereto to rotate around the axis of the lifting shaft 211, so that the clamping structure 41 connected to the connecting arm 32 rotates around the lifting shaft 211 as the center. When the two clamping structures 41 rotate to the position on the decorative plate that needs to be cut, the two clamping structures 41 clamp the decorative plate to ensure that the area near the cutting area remains horizontal. Then, the cutting assembly 42 installed on one of the clamping structures 41 starts to cut the decorative plate. After completing one cut, the two rotating mechanisms 33 drive the sleeve 31 to rotate again to adjust the position of the clamping structure 41 and the cutting assembly 42 for the next cut. By adjusting the position of the cutting mechanism 4 multiple times, a complex shape with the center of the circular clamping disk 212 as the center point can be cut on the decorative plate. During the entire cutting process, there is no need to reposition the decorative plate, thereby significantly improving the molding accuracy of the decorative plate, thereby effectively enhancing the decorative effect of the elevator.

[0035] Reference Figure 4 and Figure 5 As shown: the connecting structure 3 also includes two extension arm assemblies 34, the two extension arm assemblies 34 are respectively arranged at the two ends of the connecting arm 32, the clamping structure 41 is connected to the two extension arm assemblies 34, the extension arm assembly 34 includes a fixed arm 341, a telescopic arm 342 and a second linear driver 343, one end of the fixed arm 341 is connected to the end of the connecting arm 32, the other end of the fixed arm 341 is provided with a storage bin, the middle part of the fixed arm 341 is provided with an installation bin, the telescopic arm 342 is slidably arranged in the storage bin, the second linear driver 343 is arranged in the installation bin, and the output end of the second linear driver 343 is connected to the telescopic arm 342.

[0036] When the distance between the edge of the decorative plate to be cut and the center of the circular clamping disk 212 changes, the two extension arm assemblies 34 will cooperate to make dynamic adjustments. If the distance between the required cutting edge and the center of the circle increases, the second linear drive 343 will drive the telescopic arm 342 to extend from the storage bin of its fixed arm 341. During the extension process, the telescopic arm 342 will synchronously push the cutting assembly 42 to a farther position through the clamping structure 41 to ensure that the cutting assembly 42 can reach and cut the edge of the decorative plate farther from the center of the circle. On the contrary, if the distance between the required cutting edge and the center of the circle decreases, the second linear drive 343 will drive the telescopic arm 342 to retract into the storage bin, so that the distance between the cutting mechanism 4 and the center of the circular clamping disk 212 is correspondingly reduced, ensuring that the cutting assembly 42 can accurately cut the edge of the decorative plate closer to the center of the circle, so that the cutting mechanism 4 can realize cutting of the edges of decorative plates at different distances from the center of the circular clamping disk 212, thereby adapting to the cutting requirements of different distances and greatly improving the flexibility of the cutting operation.

[0037] Reference Figure 4 and Figure 5 As shown: the connection structure 3 also includes a stabilizing structure 35, which is arranged between the two extension arm assemblies 34. The stabilizing structure 35 includes a first hanging plate 351 and a plurality of stabilizing assemblies 352. The two ends of the first hanging plate 351 are connected to the two extension arm assemblies 34. The plurality of stabilizing assemblies 352 are installed on the first hanging plate 351 at equal intervals. One end of the stabilizing assembly 352 is connected to the circular clamping disk 212. The stabilizing assembly 352 includes a stabilizing arm 3521 and a roller 3522. One end of the stabilizing arm 3521 is connected to the first hanging plate 351, and the roller 3522 is arranged at the other end of the stabilizing arm 3521. An inwardly inclined annular surface is provided on the outer circumferential surface of the circular clamping disk 212, and the roller 3522 is tangent to the inwardly inclined annular surface.

[0038] When the two clamping structures 41 clamp the decorative sheet at the same time, the clamping structure 41 will be subjected to the opposite direction force from the decorative sheet. In addition, when the cutting assembly 42 performs the cutting operation, the decorative sheet will exert a reverse force on the cutting assembly 42, and the force will be further transmitted to the clamping structure 41 carrying the cutting assembly 42, resulting in the two clamping structures 41 having a tendency to separate from each other, weakening the clamping effect of the two clamping structures 41 on the decorative sheet. Therefore, two stabilizing structures 35 are provided to correspond to the two clamping structures 41 respectively, and the roller 3522 and the roller 3522 are connected to each other. The circular clamping plate 212 contacts the inwardly inclined annular surface. When adjusting the position of the cutting mechanism 4, the roller 3522 can roll along the inwardly inclined annular surface. The circular clamping plate 212 will apply downward pressure to the roller 3522. The pressure is transmitted to the first hanging plate 351 via the stabilizing arm 3521. The first hanging plate 351 then applies a downward force to the two extension arm assemblies 34 at the same time, effectively offsetting the reverse force exerted on the clamping structure 41 when clamping the decorative sheet, thereby ensuring that the clamping structure 41 continuously and stably clamps the decorative sheet.

[0039] Reference Figure 3 and Figure 6 As shown: the clamping mechanism 2 also includes a synchronous motion mechanism 22, which includes two lifting plates 221 and two first driving structures 222; the two lifting plates 221 correspond to the two clamping structures 21 respectively, the center position of the lifting plate 221 is connected to the lifting shaft 211, and a guide column 2211 is arranged on the lifting plate 221, and one end of the guide column 221 vertically passes through the rectangular mounting frame 1; the two first driving structures 222 are respectively arranged on the two side surfaces of the rectangular mounting frame 1, the first driving structure 222 is connected to the same end of the two lifting plates 221, the first driving structure 222 includes two moving blocks 2221 and a bidirectional driving unit 2222, the two moving blocks 2221 are symmetrically arranged about the vertical middle plane of the rectangular mounting frame 1, the upper and lower ends of the two moving blocks 2221 are provided with first driving plates 2223, the two ends of the first driving plate 2223 are respectively hinged to the moving block 2221 and the lifting plate 221, and the bidirectional driving unit 2222 is transmission-connected to the two moving blocks 2221.

[0040] When the decorative plate is placed between the two clamping structures 21, the synchronous motion mechanism 22 is started, and the bidirectional driving units 2222 in the two first driving structures 222 work simultaneously. The first driving structure 222 drives the two moving blocks 2221 to move away from each other, and the two moving blocks 2221 both apply a force toward the middle of the rectangular mounting frame 1 to the two lifting plates 221 through the two first driving plates 2223. Since both ends of the lifting plates 221 are subjected to the same force, the two lifting plates 221 are translated toward the middle of the rectangular mounting frame 1, and the lifting plates 221 are transmitted to the circular clamping disk 212 through the lifting shaft 211, driving it to move toward the decorative plate. In this process, it is ensured that the two clamping structures 21 can keep moving synchronously, thereby achieving a uniform and stable clamping effect on the decorative plate, and effectively avoiding the deviation or damage to the decorative plate caused by uneven clamping.

[0041] Reference Figure 3 , Figure 7 and Figure 8 As shown: the clamping mechanism 2 also includes a clamping outward expansion structure 23, the clamping outward expansion structure 23 includes a plurality of outward expansion components 231, the plurality of outward expansion components 231 are arranged on the clamping side of the circular clamping disk 212, and the plurality of outward expansion components 231 are arranged in a ring shape and at equal intervals about the axis of the circular clamping disk 212, the outward expansion component 231 includes a guide seat 2311, a telescopic rod 2312, a first pressure block 2313 and a first rubber pad 2314, the guide seat 2311 is fixedly connected to the circular clamping disk 212, the telescopic rod 2312 is arranged along the diameter direction of the circular clamping disk 212, and the telescopic rod 2312 is slidably connected to the guide seat 2311, the first pressure block 2313 is arranged at the end of the telescopic rod 2312, and a first rubber pad 2314 is arranged on one side of the first pressure block 2313.

[0042] The diameter of the circular clamping disk 212 is fixed, resulting in a fixed area of ​​the decorative plate clamped by it, and thus the supporting effect on the decorative plate near the edge of the circular clamping disk 212 is limited. When a decorative plate with a larger width needs to be clamped, the circular clamping disk 212 cannot provide effective support for the plate portion away from its edge. By setting up a number of outward expansion components 231, before the clamping operation begins, all telescopic rods 2312 expand outward along their respective axes, so that the first pressure block 2313 and the first rubber pad 2314 thereon can exceed the range of the circular clamping disk 212. Subsequently, the circular clamping disk 212 moves toward the decorative plate until the first rubber pad 2314 is in close contact with the surface of the decorative plate. The first rubber pad 2314 can prevent scratches on the surface of the decorative plate. By adjusting the moving distance of the telescopic rod 2312 along its axis, the clamping structure 21 can adapt to decorative plates of different widths, ensuring that the decorative plates are effectively supported, thereby achieving the expansion of the effective support range of the circular clamping disk 212.

[0043] Reference Figure 7 and Figure 8 As shown: the clamping and expanding structure 23 also includes a second driving structure 232, which is arranged in the middle of the circular clamping disk 212, and is connected to a plurality of expansion components 231. The second driving structure 232 includes a first linear driver 2321, a synchronization plate 2322 and a plurality of second driving plates 2323. The output end of the first linear driver 2321 passes through the circular clamping disk 212 and extends to the middle of a plurality of telescopic rods 2312. The middle of the synchronization plate 2322 is connected to the output end of the first linear driver 2321. A plurality of second driving plates 2323 are arranged in a circular array around the synchronization plate 2322, and the plurality of second driving plates 2323 correspond to the plurality of telescopic rods 2312 respectively. The two ends of the second driving plate 2323 are axially connected to the telescopic rod 2312 and the synchronization plate 2322 respectively.

[0044] Before clamping the decorative plate, the second driving structure 232 works, and the first linear driver 2321 in the second driving structure 232 drives the synchronization plate 2322 to move toward the decorative plate. The synchronization plate 2322 synchronously pushes a plurality of telescopic rods 2312 to move through a plurality of second driving plates 2323. The translation distance of the synchronization plate 2322 determines the extension length of the telescopic rod 2312, thereby realizing synchronous adjustment of all external expansion components 231.

[0045] Reference Figure 7 and Fig. 9 As shown: the clamping outward expansion structure 23 also includes a middle support structure 233, which is arranged in the middle of several outward expansion components 231, and the middle support structure 233 includes a second pressure block 2331 and a second rubber pad 2332, the second pressure block 2331 is arranged parallel to one side of the synchronization plate 2322, and the second rubber pad 2332 is arranged on the second pressure block 2331.

[0046] Before the decorative sheet is fixed by the clamping structure 21, it is in a bent shape. When the multiple outward expansion components 231 clamp the decorative sheet as the circular clamping plate 212 moves, the decorative sheet located in the central part of these outward expansion components 231 may be in a concave state. By providing a middle support structure 233, before the multiple outward expansion components 231 come into contact with the decorative sheet, the second rubber pad 2332 is pre-pressed on the decorative sheet under the action of the second pressure block 2331. The originally concave decorative sheet can be restored to a horizontal state under the action of the two middle support structures 233. Subsequently, the multiple outward expansion components 231 come into contact with the decorative sheet again, thereby ensuring that the decorative sheet can remain in a horizontal state in the entire area covered by the outward expansion components 231.

[0047] Reference Figure 7 and Fig. 9As shown: the clamping outward expansion structure 23 also includes a buffer structure 234, which is arranged between the middle support structure 233 and the circular clamping disk 212. The buffer structure 234 includes a plurality of connecting rods 2341 and a plurality of springs 2343. The plurality of connecting rods 2341 are arranged in a rectangular array on the second pressure block 2331. The axis of the connecting rod 2341 is parallel to the axis of the circular clamping disk 212. One end of the connecting rod 2341 is connected to the second pressure block 2331, and the other end of the connecting rod 2341 passes through the synchronous plate 2322 and the circular clamping disk 212 in sequence, and a limiting ring 2342 is provided at the other end of the connecting rod 2341. The plurality of springs 2343 are respectively mounted on the plurality of connecting rods 2341, and the two ends of the spring 2343 are respectively abutted against the synchronous plate 2322 and the second pressure block 2331.

[0048] The middle support structure 233 will first contact the decorative plate, and then the outer expansion component 231 will contact the decorative plate. Since the circular clamping plate 212 drives the middle support structure 233 and the outer expansion component 231 to move synchronously at the same time, the middle support structure 233 continues to apply additional extrusion force to the decorative plate during the contact between the outer expansion component 231 and the decorative plate, thereby increasing the risk of extrusion deformation of the decorative plate. For this purpose, a buffer structure 234 is provided. The elastic effect of the spring 2343 in the buffer structure 234 can ensure that the distance between the second rubber pad 2332 and the decorative plate is always smaller than the first The distance between a rubber pad 2314 and the decorative plate ensures that the second rubber pad 2332 can contact the decorative plate first. After the second pressure block 2331 and the second rubber pad 2332 contact the decorative plate, the circular clamping plate 212 continues to push the expansion component 231 toward the decorative plate. During this process, the spring 2343 will be gradually compressed and effectively absorb the force exerted by the circular clamping plate 212 on the second pressure block 2331 and the second rubber pad 2332, significantly reducing the increase in the extrusion force of the second pressure block 2331 on the decorative plate, thereby reducing the risk of extrusion deformation of the decorative plate.

[0049] Reference Figure 4 and Fig.10 As shown: the clamping structure 41 includes a second hanging plate 411, a third linear drive 412, a U-shaped hanging plate 413 and a clamping plate 414; the two ends of the second hanging plate 411 are respectively connected to the two extension arm assemblies 34; there are a plurality of third linear drives 412, and the plurality of third linear drives 412 are arranged on the second hanging plate 411 at equal intervals; the U-shaped hanging plate 413 is arranged in parallel on one side of the second hanging plate 411, and the U-shaped hanging plate 413 is connected to the output ends of the plurality of third linear drives 412; the clamping plate 414 is installed on the U-shaped hanging plate 413, and the clamping plate 414 is parallel to the second hanging plate 411, and a cutting groove is opened in the middle of the clamping plate 414.

[0050] After the rotating mechanism 33 completes the position adjustment of the clamping structure 41, several third linear drives 412 are started at the same time, driving the U-shaped hanging plate 413 and the clamping plate 414 to move toward the direction of the decorative plate. The clamping plate 414 located at the lower end of the decorative plate will first contact the decorative plate, and use its upward lifting force to gradually lift the decorative plate that may have been bent. When the two clamping plates 414 are completely in contact with the decorative plate, the decorative plate will remain horizontal, and deformation of the decorative plate can be avoided when cutting the decorative plate, thereby ensuring the stability and accuracy of the decorative plate during the cutting process.

[0051] Reference Figure 4 and Fig.11 As shown: the cutting assembly 42 includes a tool holder 421, a cutting blade 422 and a plurality of fourth linear drivers 423; the tool holder 421 is arranged inside the U-shaped hanging plate 413, and the tool holder 421 is parallel to the U-shaped hanging plate 413; the cutting blade 422 is fixedly connected to the tool holder 421 by bolts; a plurality of fourth linear drivers 423 are arranged on the U-shaped hanging plate 413 at equal intervals, and the output ends of the plurality of fourth linear drivers 423 are all connected to the tool holder 421.

[0052] After the two clamping plates 414 fix the decorative sheet, the cutting stage begins, and several fourth linear drivers 423 are started at the same time to apply a uniform and stable driving force toward the decorative sheet to the cutting blade 422. The driving force ensures that the cutting blade 422 can act on the decorative sheet at a constant speed and pressure. Since several fourth linear drivers 423 apply force to the cutting blade 422 at the same time and uniformly, the cutting blade 422 can maintain a consistent cutting effect and path during the cutting process, ensuring that the cutting force applied to the decorative sheet at various locations during the cutting process is the same, thereby effectively avoiding the unevenness of the cutting edge of the decorative sheet and improving the cutting quality.

It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
