Description

Technical Field

[0001] This application relates to the field of workpiece punching technology, and in particular to a punching die tooling and punching equipment. Background Technology

[0002] In the production and application of tooling and fixture molds, window stamping is a common process. Traditional window stamping tooling molds have a simple structure and single function, and can only complete the stamping operation of a single window at a time.

[0003] For workpieces that require multiple windows to be stamped upwards along the workpiece axis, the current single-window stamping method results in low stamping efficiency. Furthermore, the stamped workpiece still needs to be manually removed from the mold, which poses a certain degree of danger. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a punching die tooling and punching equipment, which can solve the above-mentioned problems existing in the prior art.

[0005] To achieve the above objectives, this application adopts the following technical solution: On the one hand, a punching die tooling is provided, which includes: A die core has a die hole at its center for connecting the workpiece to be punched, and multiple cutters are slidably connected on the die core, the cutters being disposed around the die hole; An ejector unit, connected to the workpiece within the die cavity, is used to drive the workpiece to move from inside the die cavity to outside the die cavity; and The drive unit is used to drive the cutter to move between a first position and a second position along its own axis. When the drive unit drives the cutter to move from the first position to the second position, the cutter cuts the workpiece through the blade at its end.

[0006] Preferably, it also includes a base for connecting the mold core, the ejector unit and the drive unit.

[0007] Preferably, the base has a through hole, and the mold core is detachably fixedly connected to the through hole; and The ejector unit is connected below the through hole; and The drive unit is connected to the periphery of the base in conjunction with the position of the cutter.

[0008] Preferably, it also includes a support rod connected to the mold hole, and one end of the support rod has a protrusion for positioning and connecting the workpiece; The support rod has a through hole at its center and a clearance hole corresponding to the cutter on its side wall. The clearance hole is connected to the through hole at the center of the support rod.

[0009] Preferably, the ejection unit includes: The ejector cylinder has its housing fixedly connected to the base, and multiple ejector rods are fixedly connected to the cylinder rod of the ejector cylinder; The ejector rod is slidably disposed on the side wall of the support rod, and the ejector rod passes through the support rod.

[0010] Preferably, the driving unit includes: The drive cylinder has its housing fixedly connected to the base and located on the periphery of the base; The slider is slidably connected to the base along the corresponding cutter, with one end of the slider connected to the cylinder rod of the drive cylinder and the other end fixedly connected to the cutter.

[0011] Preferably, the ejector cylinder and the drive cylinder are pneumatic cylinders or servo electric cylinders.

[0012] Preferably, the base has a groove, and the slider is slidably connected within the groove.

[0013] Preferably, it also includes a support block, which is fixedly connected to the bottom of the base.

[0014] On the other hand, this disclosure also provides a punching apparatus, which includes punching die tooling as described in any of the above.

[0015] The beneficial effects of this application are as follows: 1. By evenly distributing cutting blades around the mold core and coordinating with the drive unit, multiple windows of a cylindrical workpiece can be simultaneously stamped. Simultaneously, the ejection unit automatically removes the workpiece without manual intervention, ensuring a continuous and uninterrupted processing flow and further improving overall production efficiency. The cutting blades are evenly distributed around the mold core, and each drive unit is precisely matched to its corresponding cutting blade, ensuring balanced force and synchronized movement of each blade. This effectively avoids window size deviations caused by uneven power distribution.

[0016] 2. The ejection unit drives multiple ejection rods to move synchronously through the ejection cylinder. After the workpiece is stamped, it automatically ejects the die core from the support rod. The entire process does not require manual material handling, which not only reduces the cost of manual operation, but also avoids the risk of mechanical injury that may occur during manual material handling, thus improving the safety of equipment operation.

[0020] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0023] like Figures 1 to 6 As shown, this embodiment provides a punching device equipped with a punching die fixture. The punching die fixture allows for the simultaneous punching of multiple windows onto a cylindrical workpiece. Furthermore, after punching, the workpiece can be automatically ejected from the fixture, thus eliminating the need for manual material handling.

[0024] Specifically, the punching die fixture provided in this disclosure includes a die core 100, an ejector unit 200, and a drive unit 300. The die core 100 is used to connect the workpiece, and a cutter 120 for punching is connected to the die core 100. The drive unit 300 is used to drive the cutter 120 to punch the workpiece; after the workpiece is punched in the die core 100, it can be ejected from the die core 100 by the ejector unit 200.

[0025] Furthermore, a die hole 110 for connecting workpieces is provided at the center of the die core 100, and cutters 120 are evenly distributed around the periphery of the die core 100. During the sliding process relative to the die core 100, the ends of the cutters 120 can extend into the die hole 110. Therefore, when a workpiece is placed inside the die hole 110, the drive unit 300 drives the cutters 120 to slide along their own axis, thereby achieving the stamping of the workpiece. By evenly distributing the cutters 120 around the periphery of the die core 100, and by allowing the cutters 120 to simultaneously extend into the die hole 110 under the action of the drive unit 300 to stamp the columnar workpiece, this design enables simultaneous processing of multiple windows of the workpiece in one operation, avoiding the cumbersome process of traditional single-window step-by-step stamping and significantly improving processing efficiency. Meanwhile, the cutter 120 is evenly distributed around the mold core 100, and the cutter 120 is driven by the drive unit 300 to slide stably along its own axis to achieve stamping, which ensures the uniformity of the stamping position of each window and the dimensional accuracy, and improves the workpiece processing quality.

[0026] Understandably, the ejector unit 200 is connected to the workpiece within the die hole 110 and is used to drive the workpiece after punching to move from inside the die hole 110 to the outside. Simultaneously, the drive unit 300 drives the cutter 120 to move along its own axis between a first position 301 and a second position 302. When the drive unit 300 drives the cutter 120 to move from the first position 301 to the second position 302, the cutter 120 punches the workpiece through its own end blade.

[0027] After the workpiece is stamped, the ejector unit 200 can drive the workpiece to move automatically from inside the die hole 110 to the outside, eliminating the need for manual material handling. This not only reduces manual operation costs but also lowers the safety risks that may exist during manual material handling, while ensuring the continuity of the processing flow. The die core 100, the ejector unit 200, and the drive unit 300 work together. The drive unit 300 not only realizes the stamping action of the cutter 120 but also works with the ejector unit 200 to complete the unloading. The overall structure is compact, and the power transmission is efficient, ensuring the stability and reliability of the stamping and unloading processes and reducing the risk of equipment failure.

[0028] In one embodiment, the punching die tooling provided in this disclosure further includes a base 10, which is used to connect the die core 100, the ejection unit 200 and the drive unit 300.

[0029] Furthermore, a through hole is provided on the base 10, and the mold core 100 is detachably fixedly connected to the through hole. Meanwhile, the ejector unit 200 is connected below the through hole, and the drive unit 300 is connected to the periphery of the base 10 according to the specific position of the cutter 120. By adding the base 10 to integrate the mold core 100, ejector unit 200, and drive unit 300, the core components form a unified assembly basis, reducing vibration or displacement errors caused by dispersed layouts and enhancing the stability and reliability of the overall equipment structure. At the same time, the mold core 100 is detachably fixed to the through hole of the base 10, facilitating quick replacement of the mold core 100 according to different specifications or types of workpieces without adjusting the overall equipment structure, significantly improving the equipment's adaptability to diverse processing needs.

[0030] In one embodiment, three cutters 120 are provided, and the three cutters 120 are evenly distributed along the periphery of the mold core 100. It is understood that three sets of drive units 300 are also provided, with each set of drive units 300 corresponding to one cutter 120.

[0031] Understandably, the drive unit 300 is positioned around the base 10 based on the location of the cutter 120, and the three drive units 300 correspond to the three evenly distributed cutters 120. This ensures that each cutter 120 receives balanced force and moves synchronously, avoiding workpiece window size deviations caused by uneven power distribution, and further improving the accuracy and consistency of stamping. The design of the ejector unit 200 located below the through hole and the drive units 300 arranged around the periphery, combined with the unified support of the base 10, makes the power transmission path between the ejection and unloading action and the stamping action of the cutter 120 more reasonable.

[0032] Specifically, the drive unit 300 includes a drive cylinder 310, the housing of which is fixedly connected to the base 10. A slider 320 is slidably connected to the base 10 along the sliding direction of the cutter 120. The piston rod of the drive cylinder 310 is fixedly connected to the slider 320, so that the drive cylinder 310 drives the slider 320 to slide on the base 10. Simultaneously, the other end of the slider 320 is fixedly connected to the end of the cutter 120, so that the slider 320 can synchronously drive the cutter 120 to move on the base 10 during its sliding process.

[0033] Furthermore, a groove 11 for sliding the slider 320 can be provided on the base 10, and the slider 320 is slidably disposed in the groove 11. By disposing the slider 320 in the groove 11, the stability of the slider 320 during the sliding process can be effectively improved.

[0034] Understandably, the drive unit 300 uses a drive cylinder 310 as its power source. Its housing is fixed to the base 10, and the piston rod is directly connected to the slider 320. Through the rigid connection between the slider 320 and the cutter 120, the punching action of the cutter 120 is effectively ensured to be responsive and the force transmission is precise. At the same time, a groove 11 is provided on the base 10 for the slider 320 to slide. The groove 11 forms a rigid constraint on the slider 320, effectively limiting the movement direction of the slider 320 and preventing deviation, shaking, or jamming during the sliding process.

[0035] In one embodiment, a support rod 400 is also connected within the die hole 110 of the die core 100. The support rod 400 is disposed within the die hole 110 to support the workpiece within the die hole 110. Specifically, one end of the support rod 400 has a protrusion 401 for positioning the workpiece, and the protrusion 401 is cylindrical. At the same time, there is a gap 402 between the protrusion 401 and the inner wall of the die hole 110, so that the workpiece can be fitted onto the protrusion 401 through the gap 402. After the workpiece is fitted onto the protrusion 401 at the end of the support rod 400, one end of the workpiece is engaged in the gap 402 between the protrusion 401 and the inner wall of the die hole 110. This structure improves the stability of the workpiece connection, forms a double limit, effectively restricts the radial displacement and sway of the workpiece during the stamping process, and ensures the accurate stamping position of the cutter 120.

[0036] A through hole is provided at the center of the support rod 400, and a clearance hole corresponding to the cutter 120 is also provided on its side wall, with the clearance hole communicating with the through hole at the center of the support rod 400. Therefore, waste generated during the workpiece punching process can be discharged through the through hole at the center of the support rod 400, preventing waste from accumulating in the die hole 110 and obstructing the movement of the cutter 120 or scratching the workpiece surface, ensuring a continuous and smooth punching process. The clearance hole precisely corresponds to the position of the cutter 120, providing sufficient space for the cutter 120 to punch while preventing mechanical interference between the support rod 400 and the cutter 120.

[0037] In one embodiment, the ejection unit 200 includes an ejection cylinder 210, the housing of which is fixedly connected to the base 10, and a plurality of ejection rods 220 are fixedly connected to the piston rod of the ejection cylinder 210. The ejection rods 220 are slidably disposed on the side wall of the support rod 400 and penetrate through the support rod 400. Therefore, after the workpiece is punched, the ejection cylinder 210 of the ejection unit 200 drives the ejection rods 220 to eject the workpiece from the mold core 100 from the support rod 400. The design of the ejection rods 220 being slidably disposed on the side wall of the support rod 400 and penetrating through the support rod 400 allows the ejection action to be adapted to the support and waste discharge functions of the support rod 400, without affecting the positioning of the workpiece by the support rod 400 and the unobstructed waste channel, while also accurately acting on the workpiece to achieve ejection.

[0038] It should be noted that the ejector cylinder 210 and the drive cylinder 310 are either pneumatic cylinders or servo electric cylinders. However, they are not limited to these; the specific cylinder structure of the ejector cylinder 210 and the drive cylinder 310 can be determined according to actual requirements.

[0039] In one embodiment, a support block is fixedly connected to the bottom of the base 10, which can raise the base 10 by a certain distance. Two sets of support blocks are provided, which effectively improves the stability of the device during actual use. Specifically, two sets of support blocks are provided at the bottom of the base 10. By increasing the bottom support area and raising the base 10, the impact force and vibration during equipment operation are effectively dispersed, reducing processing errors caused by the shaking of the base 10. Especially in high-frequency stamping scenarios, this significantly improves the overall structural stability of the equipment. Furthermore, raising the base 10 by the support blocks provides more ample space for the installation and maintenance of components such as the ejector cylinder 210 below the base 10, and also facilitates the observation and cleaning of waste material discharged from the through hole of the support rod 400, improving the convenience of daily equipment maintenance.

[0040] In summary, this disclosure provides a punching die fixture and punching equipment. By evenly distributing cutters 120 around the periphery of the die core 100, and coordinating with the drive unit 300, multiple windows of a cylindrical workpiece can be punched synchronously in one go. Simultaneously, the ejection unit 200 automatically removes the workpiece without manual intervention, ensuring a continuous and uninterrupted processing flow and further improving overall production efficiency. The cutters 120 are evenly distributed around the periphery of the die core 100, and each set of drive units 300 is precisely matched with its corresponding cutter 120, ensuring balanced force and synchronized movement of each cutter 120, effectively avoiding window size deviations caused by uneven power distribution.

[0041] The ejection unit 200 drives multiple ejection rods 220 to move synchronously through the ejection cylinder 210. After the workpiece is stamped, it automatically ejects the mold core 100 from the support rod 400. The entire process does not require manual material handling, which not only reduces the cost of manual operation, but also avoids the risk of mechanical injury that may occur during manual material handling, thus improving the safety of equipment operation.
