DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0040] It should also be understood that the terms used in this utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in this utility model specification and the appended claims, the singular forms "a", "an" and "the" are intended to include plural forms unless the context clearly indicates otherwise.

[0041] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0042] Please refer to Figure 1 As shown, the present invention relates to a die-cutting device, which includes a feeding device 10, a punching device 20, an arc pressing device 30, a straightening device 40, and a bending and cutting device 50. The straightening device 40 is arranged at the front end, the bending and cutting device 50 is arranged at the rear end, and the punching device 20 and the arc pressing device 30 are arranged between the feeding device 10 and the bending and cutting device 50.

[0043] The straightening device 40 is arranged at the front end of the feeding device 10, and is used for straightening the blade plate 60. Since the blade plate 60 is often a coil, a straightening device is needed to straighten the blade plate 60 to ensure the normal operation of subsequent work.

[0044] The feeding device 10 is arranged at the rear end of the straightening device, and is used to transport the blade plate vertically and parallel to the rear end. Figure 1 and Figure 15 ) is set on.

[0045] The punching device 20 is a feeding device provided at the rear end of the feeding device 10, and is used to impact the side of the knife plate 60 in a direction perpendicular to the moving direction of the knife plate 60, thereby forming a notch required for processing, and / or breaking the knife plate. During transportation, the knife plate 60 is transported vertically, and when the knife plate 60 is impacted, the side of the vertically transported knife plate is punched in the horizontal direction. It should be noted that when an abnormality occurs during the arc pressing device or the bending and cutting device process, in order to avoid affecting the normal production of the subsequent knife die, the punching device can be used for punching, and the waste knife plate can be directly cut off for recycling, and only the mold of the punching device needs to be adjusted.

[0046] The arc pressing device 30 is arranged at the rear end of the punching device 20, and is used to bend the blade plate 60, and when bending, the blade plate is bent from its upper end to the lower end (such as Figure 15 direction of the arrow shown) to form an arc-shaped cutting blade (such as Figure 16 shown).

[0047] The bending and cutting device 50 is disposed at the rear end of the arc pressing device 30, and is used to receive the arc-shaped cutting blade, and bend and cut the arc-shaped cutting blade to form a finished knife die 70 (such as Figure 14As shown). The specific working process of this device is as follows: before operation, the curvature of the cutting die to be produced is preset. The raw material of the rolled cutting plate 60 first passes through the straightening device 40 to straighten the raw material; then the raw material of the cutting plate 60 passes through the feeding device 10, which provides power for the transportation of the cutting plate 60 and transports the cutting plate 60 to the punching device 20. The punching device 20 punches the side of the cutting plate 60 to punch out a notch of the set shape on the cutting plate 60. It should be noted that the notch mainly includes a node, a bridge, and a square hole. The node is a notch punched at the bottom of the cutting plate to facilitate arc forming. The bridge is a specific notch punched at the bottom of the cutting plate. This notch is a clearance position for the curved cutting die to be installed on the template. The square hole is a square notch punched in the middle of the blade body, which is used to fix the cutting die to the cutting template. Of course, the notch is not limited to the three types mentioned above and can be set according to different needs. Then the cutting plate 60 is transported to the position of the arc pressing device 30, and the cutting plate 60 is pressed into a preset arc (for example, an arc of blade); the blade plate 60 then enters the position of the bending and cutting device 50, and the bending and cutting device 50 bends the curved cutting blade. After the bending is completed, it is cut to produce a finished cutting die 70, and multiple cutting dies are produced according to the above process.

[0048] Please refer to Figure 2 As shown, the straightening device 40 includes a guide roller group 41, a straightening wheel 42, a support wheel 43, and a third pressure wheel 44. The support wheel 43 and the third pressure wheel 44 are arranged at the front end of the straightening device 40 and are used to allow the blade plate 60 to pass through. The third pressure wheel 44 is arranged above the support wheel 43. The support wheel 43 is used to support the bottom of the blade plate 60, and the third pressure wheel 44 is used to press the top of the blade plate 60 to ensure that the blade plate 60 passes between the support wheel 43 and the third pressure wheel 44. There are two guide roller groups 41, and each guide roller group 41 includes two guide wheels 411 arranged relatively spaced apart. The straightening wheels 42 are arranged between the two groups of guide roller groups 41. There are multiple straightening wheels 42, and the multiple straightening wheels 42 are arranged in two rows at intervals, and the straightening wheels 42 on the two rows are staggered. The straightening wheels 42 press the side of the passing knife plate 60 to adjust the flatness of the knife plate 60 to ensure the normal operation of subsequent work and the accuracy of the finished knife die.

[0049] It should be noted that the order of the punching device and the arc pressing device can be adjusted, that is, the arc pressing can be performed first and then the punching, or the punching can be performed first and then the arc pressing.

[0050] Please refer to Figure 3 and Figure 4As shown, the feeding device 10 includes a feeding servo motor 11, a first ball screw 12, and a clamping mechanism 13. The feeding servo motor 11 is in driving connection with the first ball screw 12, which in turn is in driving connection with the clamping mechanism 13. The feeding servo motor 11 drives the first ball screw 12 to rotate, thereby driving the clamping mechanism 13 along the first ball screw 12. The clamping mechanism 13 is used to move the cutting plate toward the rear end.

[0051] Please refer to Figure 4-Figure 7As shown, the clamping mechanism 13 includes a clamping cylinder 131, a connecting plate 132, a clamping lever 133, a fixed shaft 134, a fixed plate 135, a sliding block 136, and a feeding claw 137. There are two fixed plates 135, which are spaced apart. The sliding block 136 is slidably disposed between the two fixed plates 135. One end of the connecting plate 132 is fixedly connected to the two fixed plates 135, and the other end of the connecting plate 132 is fixedly connected to the clamping cylinder 133. One end of the fixed shaft 134 is connected to one of the fixed plates 135, and the other end of the fixed shaft 134 is connected to the other fixed plate 135. The fixed shaft 134 penetrates into the clamping lever 133 so that the clamping lever 133 can rotate around the fixed shaft 134. One end of the clamping lever 133 is rotatably connected to a connecting rod 138, and the other end of the clamping lever 133 is rotatably connected to the output shaft of the clamping cylinder 131. The sliding block 136 is fixedly connected to the connecting rod 138, so that the ejection and reset of the clamping cylinder 131 can drive the connecting rod 138 and the sliding block 136 to move up and down. The sliding block 136 is provided with a first slide rail 1362 and a second slide groove 1361. The feeding claw 137 includes a first slide groove 1372 and a top block 1371. The first slide groove 1371 is slidably provided on the first slide rail 1362, and the top block 1372 is provided in the second slide groove 1361. The bottom surface of the second slide groove 1361 is inclined, and the depth of the bottom surface of the second slide groove 1361 gradually increases from top to bottom. That is, when the sliding block 136 moves downward, the feeding claw 137 moves inward. There are two sliding blocks 136 and two feeding claws 137. The two sliding blocks 136 are arranged opposite each other, and the two feeding claws 137 are arranged opposite each other, and the two feeding claws are movably arranged between the two sliding blocks. As the sliding block 136 moves downward, the two feeding claws 137 move upward. Under the action of the inclined second slide 1361, the distance between the two feeding claws 137 decreases, so that the two feeding claws 137 can clamp the cutting plate 60 between them. That is, when the clamping cylinder 131 is ejected, the clamping lever 133 rotates about the fixed axis 134, thereby driving the connecting rod 138 and the sliding block 136 downward. The feeding claws 137 move upward along the first slide rail 1362. Under the action of the ejection block 1372 and the second slide 1361, the distance between the two feeding claws 137 decreases, thereby clamping the cutting plate 60 and moving the cutting plate 60. When the clamping cylinder 131 is reset, the fixing block 134 moves upward so that the feeding claws 137 move downward relative to the fixing block 135 to increase the distance between the two feeding claws 137 to release the cutting plate 60 .

[0052] During the feeding process, the clamping mechanism 13 clamps the cutting plate 60, and the feeding servo motor 11 starts, driving the ball screw 12 to rotate, which in turn drives the clamping mechanism 13 to move toward the rear end, completing the feeding process. When the clamping mechanism 13 reaches its limit position, the clamping mechanism 13 releases the cutting plate 60, and the feeding servo motor 11 drives the clamping mechanism 13 to move toward the front end. After returning to the origin, the feeding action is repeated, completing the continuous feeding process.

[0053] Please refer to Figure 8 As shown, the punching device 20 includes a punching servo motor 21, a power slider 22, a mold push-pull block 23, and a mold 24. The punching servo motor 21 is in transmission connection with the power slider 22, which is in transmission connection with the mold push-pull block 23, which is in transmission connection with the mold 24. The mold 24 is used to punch the blade plate 60 to punch out a preset notch shape.

[0054] Specifically, the punching servo motor 21 is connected to the power slider 22 and the mold push-pull block 23 through the bridge power camshaft 25. The punching servo motor 21 drives the bridge power camshaft 25 to rotate. The eccentricity of the bridge power camshaft 25 pushes the power slider 22 to move linearly, thereby driving the mold push-pull block 23 to impact the mold 24, thereby punching the required notch on the side of the blade. The mold 24 includes a groove 241 and a punch 242. The punch 242 is connected to the mold push-pull block 23 through the mold push-pull block 23. The punch 242 is driven by the mold push-pull block 23 to move toward the die 241 to impact.

[0055] The punching device 20 further includes a mold vertical adjustment mechanism 27 , which is in transmission connection with the mold 24 to drive the mold 24 to move up and down to produce different punching notches.

[0056] Specifically, the mold vertical adjustment mechanism 27 includes a mold vertical servo motor 271 and a second ball screw 272. The mold vertical servo motor 271 is transmission-connected to the second ball screw 272, which is transmission-connected to the mold 24. The mold vertical servo motor drives the ball screw to rotate, thereby driving the mold to move up and down, so that the notch to be punched is aligned with the position of the blade plate to produce the required notch. The mold also includes a slide member 26, which is fixedly connected to the punch 242 of the mold 24. The slide member 26 includes a slide groove portion 261. The mold push-pull block 23 includes a sliding portion 231 slidably disposed within the slide groove portion 261. When the mold vertical adjustment mechanism 22 drives the mold 24 to move up and down, the sliding portion 231 of the mold push-pull block 23 slides within the slide groove portion 261. The punch 242 includes a plurality of notched punch units in sequence from top to bottom, and the die also includes a plurality of notched die units that match the notched punch units in sequence. During each impact, only one notched punch unit and one notched die unit are aligned with the passing blade, so that the required notch can be punched out. When other notches need to be punched, the position of the die 24 is adjusted through the die upper and lower adjustment mechanism 22 to punch out other notches.

[0057] Please refer to Figure 9 and Figure 10 As shown, the arc pressing device 30 includes a clamping mechanism 31 and an arc pressing mechanism 32. The clamping mechanism 31 is arranged near the rear end of the punching device 20, and the arc pressing mechanism 32 is arranged near the front end of the bending and cutting device 50. The clamping mechanism 31 is used to clamp the knife plate 60, and the arc pressing mechanism 32 is used to bend the knife plate 60, so that the knife plate rotates from its upper end toward the lower end of the knife plate 60 to bend the knife plate 60 into a preset curvature to produce knife molds with different curvature sizes.

[0058] The clamping mechanism 31 includes a first arc-pressing support wheel 312 and a first pressing wheel 311. The first arc-pressing support wheel 312 is arranged below the first pressing wheel 311. The first arc-pressing support wheel 312 supports the bottom of the knife plate. The first pressing wheel is arranged above the knife plate. It is used to press the knife plate 60 to prevent the knife plate 60 from shaking when bending, so as to ensure the accuracy of the bending curvature of the knife.

[0059] Specifically, the number of the pressing mechanisms 31 is set to at least one group, such as Figure 9 and Figure 10As shown, there are two sets of clamping mechanisms 31. The first arc-pressing support wheel 312 is arranged below the first pressing wheel 311. A groove portion is provided on the first arc-pressing support wheel 312 to accommodate the bottom of the cutting plate 60. The size of the groove portion is adapted to the size of the cutting plate 60. The first pressing wheel also includes a groove portion that cooperates with the top of the cutting plate 60. The first arc-pressing support wheel 312 is mainly used to support the cutting plate 60. The first pressing wheel 311 is mainly used to press the cutting plate to ensure that the cutting plate 60 is pressed during operation without affecting the flow of the cutting plate 60 to the next process. The specific parameters are not described here in detail and can be set according to actual needs.

[0060] The arc pressing mechanism 32 includes a second press wheel 321, an arc pressing servo motor 322, a second press wheel 323, an arc pressing support shaft 324, and a transmission plate 325. The arc pressing servo motor 322 is in transmission connection with the arc pressing support shaft 324. The arc pressing support shaft 324 is rotatably arranged at the axis center of the second press wheel 323. The arc pressing support shaft 324 is in transmission connection with the transmission plate 325. The second press wheel 323 and the second press wheel 321 are mounted on the transmission plate 325. The arc pressing servo motor 322 drives the arc pressing support shaft 324 to rotate. The arc pressing support shaft 324 then drives the transmission plate 325 and the second press wheel 321 to rotate around the arc pressing support shaft 324, so as to rotate the transported cutting plate 60 from the upper end to the lower end of the cutting plate according to a preset curvature, so as to bend the cutting plate into the preset curvature. It should be noted that the above-mentioned arc pressing servo motor only drives the transmission plate and the second pressing wheel to rotate around the arc pressing support shaft to place the second pressing wheel in an appropriate position, and does not drive the second pressing wheel and the second arc pressing support wheel to rotate.

[0061] Specifically, the arc-pressing servo motor 322 can be connected to the arc-pressing support shaft via a first transmission gear 326 and a second transmission gear 327. The second transmission gear 327 moves synchronously with the arc-pressing support shaft. The first transmission gear 326 is connected to the rotating shaft of the arc-pressing servo motor 322, and the second transmission gear 327 meshes with the first transmission gear 326. The arc-pressing support shaft 324 is rotatably disposed at the axis center of the second arc-pressing support wheel 323, and the second transmission gear is fixedly connected to the arc-pressing support shaft 324. The arc-pressing support shaft 324 is in transmission connection with the transmission plate 325. During operation, the arc pressing servo motor 322 rotates to drive the first transmission gear 326 to rotate, and the first transmission gear 326 drives the second transmission gear 327 to rotate, thereby driving the arc pressing support shaft 324 to rotate, and the arc pressing support shaft 324 then drives the transmission plate 325 to rotate around the arc pressing support shaft 324. Since the second pressing wheel 321 is fixedly installed on the other end of the transmission plate 325, the second pressing wheel 321 will rotate around the arc pressing support shaft 324, thereby bending the knife plate 60 between the second pressing wheel 321 and the second arc pressing support wheel 323. The curvature of the bending can be adjusted by control. It should be noted that the principle of arc pressing forming is: the second pressing wheel 321 is rotated to different positions by the arc pressing servo motor 322, so that the second arc pressing support wheel 323, the second pressing wheel 321 and the first arc pressing support wheel 312 form a line as the tangent of the required arc. At this time, the feeding device 10 feeds forward, and the second pressing wheel 321 squeezes the knife plate, forcing the knife plate to bend into an arc.

[0062] Please refer to Figure 9 and Figure 13 As shown, the bending and cutting device 50 includes a bending positioning mechanism 51 and a bending and cutting mechanism 52. The bending positioning mechanism 51 is arranged near the rear end of the arc pressing device 30, and the bending and cutting mechanism 52 is arranged near the rear end of the bending positioning mechanism 51. The bending positioning mechanism 51 is used to rotate the bending and cutting mechanism 52 so that it is placed at a position corresponding to the preset arc of the cutting blade. The bending and cutting mechanism 52 is used to perform bending and cutting operations by pressing the side of the arc-shaped cutting blade.

[0063] The bending positioning mechanism 51 includes a bending positioning servo motor 511, a third transmission gear 512, and an adjusting tooth 513. The bending positioning servo motor 511 is in transmission connection with the third transmission gear 512, and the adjusting tooth 513 is in transmission connection with the third transmission gear 512. The adjusting tooth 513 is in transmission connection with the bending cutting assembly 52. ​​The bending positioning servo motor 511 is used to adjust the position of the bending cutting assembly 52 to adapt to cutting dies of different curvatures. It should be noted that since the first step in the operation of the device is to determine the curvature of the cutting die, the bending positioning servo motor 511 needs to be started to drive the third transmission gear 512 and the adjusting tooth 513 to rotate, thereby adjusting the position of the bending cutting mechanism 52 so that the position of the bending cutting mechanism 52 can be aligned with the cutting blade of the preset curvature, thereby ensuring that the cutting blade of the preset curvature accurately enters the position of the bending cutting mechanism 52.

[0064] The bending and cutting mechanism 52 includes a fixed plate 521, a bending and cutting servo motor 522, a shearing positioning cylinder 523, a fourth transmission gear 524, a fifth transmission gear 525, and a rotating sleeve for the bending and shearing integrated die 526. The fixed plate 521 is fixed to the adjustment gear 513. The bending and cutting servo motor 522 and the shearing positioning cylinder 523 are both located on the first surface a of the fixed plate 521. The fourth transmission gear 524, the fifth transmission gear 525, and the bending and shearing integrated die 526 are located on the second surface b of the fixed plate 521. The bending and cutting servo motor 522 is in transmission connection with the fourth transmission gear 524, which in turn is in transmission connection with the fifth transmission gear 525. The integrated bending and shearing die 526 includes a main rail 5261 and a rotating sleeve 5262. The rotating sleeve 5262 is mounted on the outside of the main rail 5261 and rotates synchronously with the fifth gear 525. The bending and cutting servo motor 522 drives the rotating sleeve 5262 to rotate, causing relative motion between the main rail 5261 and the rotating sleeve 5262, pressing the side of the arc-shaped cutting blade to bend and cut the cutting blade. The shear positioning cylinder 523 is in transmission connection with the main rail 5261 and is used to adjust the position of the main rail 5261 to switch between the bending and cutting processes.

[0065] The main guide rail 5261 is provided with a material feeding groove 5263 and a bending avoidance groove 5264. The material feeding groove 5263 is arranged along the radial direction of the main guide rail 5261 and penetrates the cylindrical side surface of the main guide rail 5261. The bending avoidance groove 5264 is arranged at the opening of the material feeding groove 5263. The rotating sleeve 5262 includes a main body 52621, a hollow portion 52622, a first groove portion 52623 and a second groove portion 52624. The main guide rail 5261 is arranged in the hollow portion 52622, and the first slot portion and the second slot portion are arranged on opposite sides of the main body. Both the first slot portion and the second slot portion face the opening of the material feeding groove 5263, so that the cutting plate 60 can penetrate into the material feeding groove 5263, and then the main guide rail 5261 and the rotating sleeve 5263 rotate relative to each other to perform bending and cutting.

[0066] It should be noted that the width of the threading groove 5263 is adapted to the thickness of the cutting plate 60. The outer diameter of the main rail 5261 is the same as the inner diameter of the rotating sleeve 5262, or the outer diameter of the main rail 5261 is slightly smaller than the inner diameter of the rotating sleeve 5262. The gap between the bending avoidance groove 5264 and the rotating sleeve 5262 is large. Therefore, when the cutting plate 60 is in the bending avoidance groove 5264, the main rail 5261 and the rotating sleeve 5262 will only bend when they rotate relative to each other, and will not cut. However, when the cutting plate 60 is not in the bending avoidance groove 5264, the main rail 5261 and the rotating sleeve 5262 will rotate relative to each other, and the cutting operation will occur. When the blade 60 just enters the bending and cutting assembly 52, the blade 60 is located in the bending avoidance groove 5264, at which time the bending operation can be performed. When the bending is completed, the shear positioning cylinder 523 is activated to push the main rail 5261 downward so that the blade 60 is located in the non-bending avoidance groove position, at which time the cutting operation can be performed. The present application sets the bending and cutting operations in one station, simplifies the length of the device, reduces the footprint of the device, and is simple to operate and convenient to use.

[0067] In an optional embodiment, for example, the knife die to be produced does not need to be bent, so the punching device punches the notch and then bends it through the arc pressing device, so there is no need for a bending and cutting device. It includes a feeding device, a punching device, and an arc pressing device. The feeding device is used to transport the knife plate vertically and parallel to the rear end. The punching device is used to impact the side of the knife plate from a direction perpendicular to the movement of the knife plate to form the notch required for processing and / or to break the knife plate. The arc pressing device is used to bend the knife plate from its upper end to the lower end to form an arc-shaped knife die product. Wherein, the punching device and the arc pressing device are arranged at the rear end of the feeding device. Please refer to the above content for the specific structure of the feeding device, the punching device and the arc pressing device.

[0068] Please refer to Figure 17As shown, the present application also relates to a knife die production method, which can use the above-mentioned equipment to produce knife die products.

[0069] The method is described in detail below. As shown in the figure, it includes the following steps:

[0070] S1. Impact the side of the cutting plate in the direction of its transfer to form the notch required for processing.

[0071] S2. Press the cutting blade to form an arc-shaped cutting blade in a circular shape, and the cutting blade rotates from the upper end of the cutting blade toward the lower end of the cutting blade.

[0072] S3. Bend and cut by pressing the side of the cutting blade to make a finished knife die.

[0073] Specifically, the above-mentioned die-cutting mold making device can be used for production. The blade plate is moved in a vertical state. The feeding device transports the upright blade plate horizontally to the punching device, where the side of the blade plate is impacted to form the notch required for processing. Subsequently, the arc pressing device presses the cutting blade to form an arc-shaped blade plate in a circular shape. When bending, the blade plate is rotated from the upper end to the lower end, and the blade plate is bent into a blade plate with a preset curvature. The specific curvature can be set according to actual needs. Finally, the curved blade plate is transported to the bending and cutting device to bend and cut the side of the blade plate to produce the finished die.

[0074] It should be noted that the above method can also be implemented using other devices, and the order of steps S1 and S2 can be interchanged.

[0075] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present application, and such modifications or substitutions should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
