Description

Technical Field

[0001] This invention relates to the field of die-cutting technology, specifically to a die-cutting fixture. Background Technology

[0002] Die-cutting molds are key molds for achieving precision cutting and forming in fields such as printing and packaging, and electronic die-cutting. Their processing accuracy directly determines the consistency of product dimensions and edge quality. With the development of precision manufacturing, die-cutting molds, as key tooling for precision cutting and forming, need to be reliably positioned and fixed during milling, engraving and other processing. The requirements for positioning accuracy and clamping efficiency in die-cutting processing are constantly increasing.

[0003] Traditional die-cutting fixtures often employ a single-direction limiting structure, enabling only individual clamping in the transverse or longitudinal direction. They cannot achieve synchronous limiting, leading to workpiece positioning misalignment and insecure clamping, which in turn affects the cutting accuracy and dimensional consistency of the die-cutting process. Furthermore, adjusting the limiting distance of traditional fixtures is cumbersome, requiring separate manual adjustments to the transverse and longitudinal clamping mechanisms. This is time-consuming when adapting to workpieces of different sizes, resulting in poor versatility. Summary of the Invention

[0004] The purpose of this invention is to provide a die-cutting fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a die-cutting fixture, comprising a die-cutting base plate and a longitudinal limiting component. A driving component for providing lateral and longitudinal clamping effects is disposed at the bottom center of the die-cutting base plate. The driving component includes a servo motor, a first gear, a connecting column, and a second gear. The first gear is mounted on the output end of the servo motor, and a connecting column is disposed at the center of the first gear. The second gear is mounted on the top of the connecting column, and two sets of the second gear are provided. A lateral limiting component for lateral positioning is mounted on one side of the top of each set of the second gears. The longitudinal limiting component for longitudinal positioning is disposed on both sides of the die-cutting base plate.

[0006] Furthermore, the die base plate has an internal groove on the side near the longitudinal limiting component, and there are two sets of internal grooves.

[0007] Furthermore, the longitudinal limiting component includes a longitudinal plate, a longitudinal fixing plate, a longitudinal clamping plate, and a longitudinal screw. The longitudinal fixing plate is provided on the outer surface of the longitudinal plate, and the longitudinal screw is installed on the internal thread of the longitudinal fixing plate. The longitudinal screw is provided at the end of the longitudinal screw.

[0008] Furthermore, the bottom of the longitudinal clamping plate is slidably disposed inside the longitudinal plate, and two sets of longitudinal limiting components are provided.

[0009] Furthermore, an adapter plate is installed at the bottom of the longitudinal plate, and a longitudinal rack is fixed to one side of the bottom of the adapter plate by bolts.

[0010] Furthermore, the longitudinal rack is provided in two sets, and the longitudinal rack is meshed with the gear.

[0011] Furthermore, the lateral limiting component includes a lateral fixing plate, a lateral screw, and a lateral clamping plate. The lateral fixing plate is internally threaded with the lateral screw, and the end of the lateral screw is provided with a lateral clamping plate. The die base plate has a slide rail inside, and the lateral clamping plate is slidably disposed inside the slide rail.

[0012] Furthermore, support frames are installed at the four corners of the bottom of the die-cutting base plate, and the base plate of the support frame is provided with a base. A rubber pad is installed on the outer surface of the bottom of the base. A connecting frame is fixedly installed on one side of the support frame, and a fixing plate is installed at the end of the connecting frame.

[0013] This invention provides a die-cutting fixture, which has the following beneficial effects: 1. The servo motor of this invention outputs power to drive a coaxial gear one to rotate. Gear one is the central gear, which simultaneously meshes with two sets of longitudinal racks and drives gear two to rotate synchronously through a connecting column. Gear one meshes with the longitudinal racks on both sides. When the gear rotates, the two sets of longitudinal racks will move synchronously in opposite directions, causing the adapter plates on both sides and the longitudinal limiting components to retract or open towards the center of the die. Gear two meshes with the transverse rack and is coaxially linked with the gear one. When it rotates, it causes the transverse rack and the transverse limiting components to retract or open towards the center of the die. This structure realizes bidirectional synchronous clamping driven by a single power source, ensuring that the die is always in the center position of the fixture and avoiding the offset caused by unilateral clamping.

[0014] 2. The horizontal screw of the horizontal limiting component and the vertical screw of the vertical limiting component of this invention can flexibly adjust the clamping distance to adapt to different sizes of die workpieces. There is no need to replace the special fixture, which improves the versatility of the fixture. The drive component adopts servo motor drive to realize automated synchronous clamping, replacing the traditional manual adjustment method, reducing the workpiece positioning and adjustment time, and improving processing efficiency.

Detailed Implementation

[0017] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0018] like Figures 1-5As shown, a die-cutting jig includes a die-cutting base plate 1, a support frame 2, a connecting frame 3, a base 4, a rubber pad 5, a fixing plate 6, a lateral limiting component 7, a lateral fixing plate 701, a lateral screw 702, a lateral clamping plate 703, a slide rail 8, an internal groove 9, a drive component 10, a servo motor 1001, a first gear 1002, a connecting column 1003, a second gear 1004, a lateral rack 11, a longitudinal limiting component 12, a longitudinal plate 1201, a longitudinal fixing plate 1202, a longitudinal clamping plate 1203, a longitudinal screw 1204, an adapter plate 13, and a longitudinal rack 14. The die-cutting base plate 1 has a drive component 10 at its bottom center for providing lateral and longitudinal clamping effects. The drive component 10 includes a servo motor 1001, a first gear 1002, a connecting column 1003, and a second gear 1004. Support frames 2 are installed at the four corners of the bottom of the die-cutting base plate 1, and the bottom plate of the support frame 2 has a bottom... The base 4 has a rubber pad 5 installed on its bottom outer surface. A connecting frame 3 is fixedly installed on one side of the support frame 2, and a fixing plate 6 is installed at the end of the connecting frame 3. The support frames 2 at the four corners of the bottom of the die base plate 1 and the base 4 form a frame support, lifting the entire fixture off the ground and reserving space for the installation and maintenance of the drive assembly 10. A gear 1002 is installed at the output end of the servo motor 1001, and a connecting column 1003 is set in the middle of the gear 1002. A gear 2 1004 is installed on the top of the connecting column 1003, and there are two sets of gear 2 1004. A transverse limiting assembly 7 for transverse positioning is installed on one side of the top of each set of gear 2 1004. A longitudinal limiting assembly 12 for longitudinal positioning is set on both sides of the die base plate 1. The drive assembly 10 drives the transverse limiting assembly 7 and the longitudinal limiting assembly 12 to move synchronously, so as to achieve precise and firm clamping of the workpiece.The drive assembly 10 is installed at the bottom center of the die base plate 1 and consists of a servo motor 1001, a first gear 1002, a connecting column 1003, and two sets of second gears 1004. The first gear 1002 is installed at the output end of the servo motor 1001. The connecting column 1003 is set in the middle of the first gear 1002, and two sets of second gears 1004 are installed on the top of the connecting column 1003. A transition plate 13 is installed at the bottom of the longitudinal plate 1201 of the longitudinal limiting assembly 12. A longitudinal rack 14 is fixed to the bottom of the transition plate 13 by bolts, and the two sets of longitudinal racks 14 are meshed with the first gear 1002. The transverse limiting assembly 7 is connected to the top side of the two sets of second gears 1004, and the second gears 1004 can drive the transverse limit assembly 7. The servo motor 1001 starts and drives the first gear 1002 to rotate. The first gear 1002 drives the two sets of longitudinal racks 14 to move synchronously through meshing. The longitudinal racks 14 drive the longitudinal plate 1201 and the longitudinal clamping plate 1203 to move synchronously through the adapter plate 13, so as to achieve precise longitudinal clamping of the workpiece. At the same time, the first gear 1002 drives the two sets of second gears 1004 to rotate synchronously through the connecting column 1003. The second gear 1004 drives the transverse clamping plate 703 of the transverse limiting component 7 to move along the slide 8, and cooperates with the longitudinal clamping plate 1203 to complete the transverse clamping of the workpiece. The entire driving process realizes synchronous limiting clamping of transverse and longitudinal directions.

[0019] like Figure 1 , Figure 3 and Figure 5As shown, the die base plate 1 has an internal groove 9 on one side near the longitudinal limiting component 12, and there are two sets of internal grooves 9. The longitudinal limiting component 12 includes a longitudinal plate 1201, a longitudinal fixing plate 1202, a longitudinal clamping plate 1203, and a longitudinal screw 1204. The longitudinal fixing plate 1202 is provided on the outer surface of the longitudinal plate 1201. A transition plate 13 is installed at the bottom of the longitudinal plate 1201, and a longitudinal rack 14 is fixed to one side of the bottom of the transition plate 13 by bolts. There are two sets of longitudinal racks 14, and the longitudinal racks 14 are meshed with gear 1002. The longitudinal screw 1204 is installed in the internal thread of the longitudinal fixing plate 1202, and the end of the longitudinal screw 1204 is provided with a longitudinal screw 1204. The bottom of the longitudinal clamping plate 1203 is slidably disposed inside the longitudinal plate 1201. The longitudinal limiting component 12 has two sets. When the longitudinal screw 1204 is rotated, the longitudinal screw 1204 and the longitudinal fixing plate 1204 are connected. The threaded engagement of 202 allows for pre-adjustment of the distance of the longitudinal clamping plate 1203 according to the workpiece size. Through the adjustment of the lateral and longitudinal distances, it is convenient to perform synchronous lateral and longitudinal clamping according to different workpiece sizes when using the drive assembly 10 for drive limiting, reducing the adjustment time in subsequent processing and improving versatility. The lateral limiting assembly 7 includes a lateral fixing plate 701, a lateral screw 702, and a lateral clamping plate 703. The lateral screw 702 is installed in the internal thread of the lateral fixing plate 701, and the lateral clamping plate 703 is provided at the end of the lateral screw 702. The die base plate 1 has a slide rail 8 inside, and the lateral clamping plate 703 is slidably disposed inside the slide rail 8. When the lateral screw 702 is rotated, the screw engages with the threaded engagement of the lateral fixing plate 701, pushing the lateral clamping plate 703 further towards the workpiece along the slide rail 8. The lateral limiting distance can be pre-adjusted according to the workpiece size that needs to be limited.

[0020] In summary, this die-cutting fixture is first based on... Figures 1-5The structure shown in the diagram has four support frames 2 installed at the bottom corners of the die base plate 1 during use. The bottom of the support frame 2 is connected to the base 4 to form a frame support structure, which lifts the entire fixture off the ground. This avoids ground impurities affecting the operation of the fixture and also provides space for the installation and maintenance of the drive component 10. The rubber pads 5 installed at the bottom of the base 4 can effectively buffer the vibration generated during processing and reduce the impact of vibration on the positioning accuracy of the workpiece. Secondly, there is a pre-limit adjustment stage, which can adjust the lateral and longitudinal limit distances in advance according to the die workpieces of different sizes, improve the versatility of the fixture, and reduce the adjustment time in subsequent processing. In terms of lateral limit, the lateral limit component 7 consists of a lateral fixing plate 701, a lateral screw 702, and a lateral clamping plate 703. The die base plate 1 has a slide rail 8 inside, and the lateral clamping plate 703 is slidably set in the slide rail 8. The operator can rotate the transverse screw 702, and use the threaded engagement between the transverse screw 702 and the transverse fixed plate 701 to push the transverse clamping plate 703 to move along the slide rail 8. According to the transverse dimensions of the workpiece, the two sets of transverse clamping plates 703 are adjusted to a suitable initial distance to prepare for subsequent precise clamping. The longitudinal limit adjustment is similar to the transverse adjustment principle. Two sets of longitudinal limit components 12 are provided, symmetrically distributed on both sides of the die base plate 1. Each set of longitudinal limit components 12 includes a longitudinal plate 1201, a longitudinal fixed plate 1202, a longitudinal clamping plate 1203, and a longitudinal screw 1204. The longitudinal fixed plate 1202 is fixed to the outer surface of the longitudinal plate 1201, the longitudinal screw 1204 is threadedly installed inside the longitudinal fixed plate 1202, and the bottom of the longitudinal clamping plate 1203 is slidably disposed inside the longitudinal plate 1201. Rotating the longitudinal screw 1204, the longitudinal clamping plate 1203 is moved by the threaded engagement. The initial distance between the two sets of longitudinal clamping plates 1203 can be adjusted according to the longitudinal dimension of the workpiece to achieve pre-limiting of the workpiece in the longitudinal direction. Combined with the lateral pre-limiting, the position of the workpiece is initially fixed to prevent the workpiece from shifting during subsequent driving clamping. Finally, the synchronous clamping is driven by the drive assembly 10, which drives the lateral limit assembly 7 and the longitudinal limit assembly 12 to move synchronously, so as to achieve precise and firm clamping of the workpiece.The drive assembly 10 is installed at the bottom center of the die base plate 1 and consists of a servo motor 1001, a first gear 1002, a connecting column 1003, and two sets of second gears 1004. The first gear 1002 is installed at the output end of the servo motor 1001. The connecting column 1003 is located in the middle of the first gear 1002, and two sets of second gears 1004 are installed on the top of the connecting column 1003. An adapter plate 13 is installed at the bottom of the longitudinal plate 1201 of the longitudinal limiting assembly 12. A longitudinal rack 14 is fixed to the bottom of the adapter plate 13 by bolts, and the two sets of longitudinal racks 14 are meshed with the first gear 1002. The transverse limiting assembly 7 is connected to the top side of the two sets of second gears 1004. Simultaneously, the second gear 1004 can drive the transverse rack 11 to achieve transverse clamping. When the servo motor 1001 starts, its output end drives the first gear 1002 to rotate, and the first gear 1002... Over-meshing drives two sets of longitudinal racks 14 to move synchronously. The longitudinal racks 14 drive the longitudinal plates 1201 and longitudinal clamping plates 1203 to move synchronously through the adapter plate 13, achieving precise longitudinal clamping of the workpiece. At the same time, gear one 1002 drives two sets of gear two 1004 to rotate synchronously through the connecting column 1003. Gear two 1004 drives the transverse clamping plate 703 of the transverse limiting component 7 to move along the slide 8, cooperating with the longitudinal clamping plate 1203 to complete the transverse clamping of the workpiece. The entire driving process achieves synchronous limiting clamping in the transverse and longitudinal directions, ensuring that the workpiece is fixed in position during processing, avoiding displacement, and ensuring the accuracy of die-cutting. In addition, two sets of built-in grooves 9 are provided inside the die-cutting base plate 1 on the side near the longitudinal limiting component 12, which can provide reserved space for the movement of the longitudinal component, avoid interference when the component moves, and ensure smooth operation of the fixture.
