Description

Technical Field

[0001] This invention relates to the field of stamping machine technology, specifically a stamping device with anti-blade wear function. Background Technology

[0002] Stamping is a crucial metal forming method in modern manufacturing, widely used in the production of metal structural parts in the automotive, aerospace, and electronics industries. In stamping processes, especially the blanking and blanking operations, the cutting edge directly engages with the sheet metal in intense shearing action, enduring immense impact, friction, and instantaneous high temperatures.

[0003] Edge wear is considered an inevitable process. When wear accumulates to a certain level, leading to excessive burrs and dimensional defects in the product, the only possible maintenance is a passive approach: stopping the machine, disassembling and replacing the entire or part of the mold. This not only reduces production efficiency but also increases the costs of mold maintenance and raw material loss. Existing stamping equipment neglects the impact of adjusting the instantaneous force during stamping operations on the cutting edge, considering different metal parts. Summary of the Invention

[0004] The purpose of this invention is to provide a stamping device with anti-blade wear function to solve the problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A stamping equipment with anti-blade wear function includes a feeder, an electrical control cabinet, a punching mechanism, and a bottom die mechanism. The feeder, electrical control cabinet, and punching mechanism are all fixedly connected to the bottom die mechanism, and the electrical control cabinet and the punching mechanism are connected by an electrical signal. The punching mechanism includes a drive mechanism, an assembly frame, and a cutting tool mechanism. The drive mechanism includes a slide block, and the cutting tool mechanism includes a base plate. The assembly frame is fixedly connected to both the slide block and the base plate.

[0006] This invention relates to a machine tool for continuous stamping of metal sheets. A feeding machine transports metal sheet raw materials to a bottom die mechanism. An operating control cabinet sends electrical signals to the stamping mechanism. A slider is fixed to an assembly base plate via an assembly frame. A drive mechanism drives a cutting tool mechanism to reciprocate downwards via the slider. The cutting tool mechanism performs continuous die stamping on the transported metal sheet raw materials. During stamping, the servo control adjusts the downward stamping speed of the cutting tool mechanism, allowing it to descend quickly while stamping slowly. This low-speed stamping significantly reduces the instantaneous impact force on the cutting edge, minimizing micro-chipping and improving the cross-sectional quality. The cutting tool mechanism has internal channels for circulating liquid cooling of the cutting tool, effectively controlling the cutting edge's operating temperature and preventing hardness reduction and thermal fatigue wear due to excessive temperature rise. Simultaneously, a lubricating oil film is formed between the cutting edge and the metal sheet raw material, mitigating rigid collisions between the cutting edge and the metal sheet and effectively reducing cutting edge wear.

[0007] Furthermore, the punching mechanism also includes a base and a feedback mechanism, the drive mechanism also includes a servo motor, the feedback mechanism includes a side frame and an adjustable damping rod, a pressure plate is provided on the slide, and there are two sets of feedback mechanisms and pressure plates. The two sets of feedback mechanisms and pressure plates are located on both sides of the slide. The bottom die mechanism includes a machine tool base, and the base is fixedly connected to the servo motor, side frame, and machine tool base. The pressure plate is in contact with the adjustable damping rod. The servo motor, feedback mechanism, tool mechanism, and electrical control cabinet are all connected by electrical signals.

[0008] The servo motor outputs a fixed-axis torque, which is transmitted to the slider, causing the slider to drive the tool mechanism to reciprocate downwards. When the tool mechanism descends to the end away from the servo motor, the pressure plate contacts the adjustable damping rod. Depending on the type of steel, the operator sends a specified electrical signal to the feedback mechanism through the control cabinet. The damping of the adjustable damping rod is adjusted according to the stiffness of different types of metal sheets. When stamping high-stiffness metal sheets, the damping of the adjustable damping rod needs to be increased to reduce the rigid collision between the cutting edge and the high-stiffness metal sheet, reduce the instantaneous impact force on the cutting edge, and reduce micro-chipping. When stamping low-stiffness metal sheets, the damping of the adjustable damping rod is decreased to increase the instantaneous collision force between the cutting edge and the low-stiffness metal sheet, avoiding the cutting edge slowly stamping the low-stiffness metal sheet, which could cause excessive shrinkage deformation of the metal sheet due to extrusion.

[0009] Furthermore, the drive mechanism also includes a slide rail and a segmented screw. The slide rail is fixedly connected to the servo motor, and the segmented screw is fixedly connected to the output end of the servo motor. The slider is also provided with an internal threaded hole, and the segmented screw is connected to the internal threaded hole by a thread. The slider is slidably connected to the slide rail.

[0010] The servo motor outputs a fixed-axis torque to the segmented screw, which rotates around its axis. Through the threaded connection between the segmented screw and the internal threaded hole, the fixed-axis torque of the segmented screw is transmitted to the slider, causing the slider to move up and down along the slide rail, thereby driving the tool mechanism to perform continuous die stamping on the transported metal sheet material.

[0011] Furthermore, the segmented screw is provided with an upper threaded section and a lower threaded section. Both the upper threaded section and the lower threaded section are connected to the internal threaded hole by threads. The upper threaded section is located above the lower threaded section, and the pitch of the upper threaded section is three times that of the lower threaded section.

[0012] The segmented screw has an upper threaded section and a lower threaded section, which are threaded to the internal threaded hole through the upper threaded section and the lower threaded section. When the rotation speed of the segmented screw around its axis is constant, the pitch of the upper threaded section and the lower threaded section determines the displacement speed of the slider along the slide rail. The pitch of the upper threaded section is three times that of the lower threaded section. That is, when the slider moves to the upper threaded section, the displacement speed is three times that of the slider in the lower threaded section. This enables rapid approach to the material, improves stamping efficiency, stamps the material at low speed, reduces the instantaneous impact force on the cutting edge, and reduces micro-chipping.

[0013] Furthermore, the feedback mechanism also includes a torque motor, a gear rod, and a gear ring. The torque motor and the adjustable damping rod are both fixedly connected to the side frame. The torque motor is connected to the electrical control cabinet via an electrical signal. The output end of the torque motor is fixedly connected to the gear rod. The gear rod meshes with the tooth surface of the gear ring, and the gear ring is rotatably connected to the adjustable damping rod.

[0014] Depending on the type of steel, the operator sends a specified electrical signal to the torque motor via the control cabinet. The torque motor outputs a fixed-axis torque to the gear rod, which rotates around its axis. Through the meshing of the gear rod and the gear ring, the gear ring rotates, and the damping is adjusted by the adjustable damping rod.

[0015] Furthermore, the tooling mechanism also includes internally cooled tools, a liquid pump, and a coolant cylinder. Several sets of internally cooled tools are provided, and these sets of internally cooled tools are linearly and evenly distributed along the substrate. The internally cooled tools, the liquid pump, and the coolant cylinder are all fixedly connected to the substrate. The internally cooled tools are provided with loop-shaped flow channels, which are located inside the internally cooled tools. The liquid pump is connected to the loop-shaped flow channels and the coolant cylinder through pipes. The liquid pump is connected to the electrical control cabinet through electrical signals.

[0016] The slider moves up and down along the slide rail, driving the cutting tool mechanism to perform continuous die stamping on the transported metal sheet raw material. The electrical control cabinet sends an electrical signal to the liquid pump, which drives the medium to circulate through the loop flow channel and the coolant cylinder through the pipeline to circulate and cool the cutting tool, effectively controlling the working temperature of the cutting edge and preventing hardness reduction and thermal fatigue wear caused by excessive temperature rise.

[0017] Furthermore, the cutting tool mechanism also includes an oil injector, an oil pump, an oil reservoir, an air jet nozzle, and a high-pressure air pump. There are two sets of air jet nozzles, which are located on both sides of the oil injector. The oil injector, oil pump, oil reservoir, air jet nozzle, and high-pressure air pump are all fixedly connected to the base plate. The oil pump is connected to the oil injector and oil reservoir through pipes, and the air jet nozzle is connected to the high-pressure air pump through pipes. The oil pump and high-pressure air pump are both connected to the electrical control cabinet through electrical signals.

[0018] When the cutting tool mechanism performs continuous stamping operations on the transported metal sheet raw material, the electrical control cabinet sends an electrical signal to the oil pump and the high-pressure air pump. The oil pump sprays the lubricating oil in the oil storage tank from the oil injector, and the high-pressure air pump sprays high-pressure gas through the air jet nozzles located on both sides of the oil injector. The high-pressure gas impacts the lubricating oil, forming a lubricating oil film between the cutting edge and the metal sheet raw material, reducing the rigid collision between the cutting edge and the metal sheet, and effectively reducing the wear of the cutting edge.

[0019] Furthermore, the bottom mold mechanism also includes a guide rail slide and a discharge cylinder. Both the guide rail slide and the discharge cylinder are fixedly connected to the machine tool base, and the discharge cylinder is located on the machine tool base at the end away from the loading machine.

[0020] The feeding machine transports metal sheet raw materials to the guide rail slide. The metal sheet raw materials slide down the guide rail slide into the material cylinder. The cutting mechanism moves up and down and back and forth to perform continuous die stamping operations on the transported metal sheet raw materials.

[0021] Compared with the prior art, the beneficial effects of this invention are as follows: This invention designs a drive mechanism where a servo motor outputs a fixed-axis torque to a segmented screw. When the rotational speed of the segmented screw around its axis is constant, the pitch of the upper thread segment is three times that of the lower thread segment. When the slider moves to the upper thread segment, its displacement speed is three times that of the slider in the lower thread segment. This achieves rapid material approach, improving stamping efficiency, low-speed material stamping, reducing the instantaneous impact force on the cutting edge, reducing micro-chipping, and improving cross-sectional quality. This invention also designs a feedback mechanism. When the tool mechanism descends to the end away from the servo motor, the pressure plate contacts the adjustable damping rod. The electrical control cabinet sends a specified electrical signal to the feedback mechanism, adjusting the damping of the adjustable damping rod according to the stiffness of different metal sheet types. When stamping high-stiffness metal sheets, the damping of the adjustable damping rod needs to be increased to reduce rigid collisions between the cutting edge and the high-stiffness metal sheet, reducing the instantaneous impact force on the cutting edge and reducing micro-chipping. When stamping low-stiffness metal sheets, the damping of the adjustable damping rod needs to be increased to reduce rigid collisions between the cutting edge and the high-stiffness metal sheet, reducing the instantaneous impact force on the cutting edge and reducing micro-chipping. The damping rod is adjusted to increase the instantaneous impact force between the cutting edge and the low-stiffness metal sheet, preventing excessive shrinkage deformation caused by the slow pressing of the cutting edge against the low-stiffness metal sheet. The invention incorporates a cutting tool mechanism with internal channels for circulating liquid cooling, effectively controlling the cutting edge's operating temperature and preventing hardness reduction and thermal fatigue wear due to excessive temperature rise. Simultaneously, a lubricating oil film is formed between the cutting edge and the metal sheet, mitigating rigid collisions and effectively reducing cutting edge wear. This invention achieves rapid material approach by the stamping tool, improving stamping efficiency. Low-speed material stamping reduces the instantaneous impact force on the cutting edge, minimizing micro-chipping. Circulating liquid cooling effectively controls the cutting edge's operating temperature, preventing hardness reduction and thermal fatigue wear due to excessive temperature rise. The formation of a lubricating oil film between the cutting edge and the metal sheet further mitigates rigid collisions and reduces cutting edge wear. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figure 1 , Figure 2 , Figure 3 As shown, the present invention provides a technical solution for a stamping equipment with anti-blade wear function, including a feeder 1, an electrical control cabinet 2, a punching mechanism 3, and a bottom die mechanism 4. The feeder 1, electrical control cabinet 2, and punching mechanism 3 are all fixedly connected to the bottom die mechanism 4, and the electrical control cabinet 2 and the punching mechanism 3 are connected by an electrical signal. The punching mechanism 3 includes a drive mechanism 32, an assembly frame 34, and a cutting tool mechanism 35. The drive mechanism 32 includes a slider 324, and the cutting tool mechanism 35 includes a base plate 351. The assembly frame 34 is fixedly connected to the slider 324 and the base plate 351.

[0026] This invention relates to a machine tool for continuous stamping of metal sheets. A feeder 1 transports metal sheet raw materials to a bottom die mechanism 4. An operating control cabinet 2 sends electrical signals to a stamping mechanism 3. A slider 324 is fixed to a base plate 351 via an assembly frame 34. A drive mechanism 32 drives a cutting tool mechanism 35 to reciprocate downwards via the slider 324. The cutting tool mechanism 35 performs continuous die stamping on the transported metal sheet raw materials. During stamping, the speed of the cutting tool mechanism 35's downward movement is controlled by a servo motor, allowing the cutting tool mechanism 35 to descend rapidly while stamping slowly. This low-speed stamping significantly reduces the instantaneous impact force on the cutting edge, minimizing micro-chipping and improving the cross-sectional quality. The cutting tool mechanism 35 has an internal channel for circulating liquid cooling of the cutting tool, effectively controlling the cutting edge's working temperature and preventing hardness reduction and thermal fatigue wear caused by excessive temperature rise. Simultaneously, a lubricating oil film is formed between the cutting edge and the metal sheet raw material, mitigating rigid collisions between the cutting edge and the metal sheet and effectively reducing cutting edge wear.

[0027] like Figure 2 , Figure 3 As shown, the punching mechanism 3 also includes a base 31 and a feedback mechanism 33. The drive mechanism 32 also includes a servo motor 321. The feedback mechanism 33 includes a side frame 331 and an adjustable damping rod 334. A pressure plate 3242 is provided on the slider 324. There are two sets of feedback mechanisms 33 and pressure plates 3242. The two sets of feedback mechanisms 33 and pressure plates 3242 are located on both sides of the slider 324. The bottom mold mechanism 4 includes a machine tool base 41. The base 31 is fixedly connected to the servo motor 321, the side frame 331, and the machine tool base 41. The pressure plate 3242 is in contact with the adjustable damping rod 334. The servo motor 321, the feedback mechanism 33, the tool mechanism 35, and the electrical control cabinet 2 are all connected by electrical signals.

[0028] The servo motor 321 outputs a fixed-axis torque, which is transmitted to the slider 324. This causes the slider 324 to drive the tool mechanism 35 to reciprocate downwards. When the tool mechanism 35 moves to the end away from the servo motor 321, the pressure plate 3242 contacts the adjustable damping rod 334. Depending on the type of steel, the operator operates the electrical control cabinet 2 to send a specified electrical signal to the feedback mechanism 33. The damping of the adjustable damping rod 334 is adjusted according to the stiffness of different types of metal sheets. When stamping high-rigidity metal sheets, the damping of the adjustable damping rod 334 needs to be increased to reduce the rigid collision between the cutting edge and the high-rigidity metal sheet, reduce the instantaneous impact force on the cutting edge, and reduce micro-chipping. When stamping low-rigidity metal sheets, the damping of the adjustable damping rod 334 is decreased to increase the instantaneous collision force between the cutting edge and the low-rigidity metal sheet, and to avoid the cutting edge slowly stamping the low-rigidity metal sheet, which could cause excessive shrinkage deformation of the metal sheet due to compression.

[0029] like Figure 3 , Figure 4As shown, the drive mechanism 32 also includes a slide rail 322 and a segmented screw 323. The slide rail 322 is fixedly connected to the servo motor 321, and the segmented screw 323 is fixedly connected to the output end of the servo motor 321. The slider 324 is also provided with an internal threaded hole 3241. The segmented screw 323 is connected to the internal threaded hole 3241 by a thread, and the slider 324 is slidably connected to the slide rail 322.

[0030] The servo motor 321 outputs a fixed-axis torque to the segmented screw 323, which rotates around its axis. Through the threaded connection between the segmented screw 323 and the internal threaded hole 3241, the fixed-axis torque of the segmented screw 323 is transmitted to the slider 324, causing the slider 324 to move up and down along the slide rail 322, thereby driving the tool mechanism 35 to perform continuous die stamping on the transported metal sheet material.

[0031] like Figure 4 As shown, the segmented screw 323 is provided with an upper threaded section 3231 and a lower threaded section 3232. Both the upper threaded section 3231 and the lower threaded section 3232 are threadedly connected to the internal threaded hole 3241. The upper threaded section 3231 is located above the lower threaded section 3232, and the pitch of the upper threaded section 3231 is three times the pitch of the lower threaded section 3232.

[0032] The segmented screw 323 has an upper threaded section 3231 and a lower threaded section 3232. The upper threaded section 3231 and the lower threaded section 3232 are threadedly connected to the internal threaded hole 3241. When the rotation speed of the segmented screw 323 around its axis is constant, the pitch of the upper threaded section 3231 and the lower threaded section 3232 determines the displacement speed of the slider 324 along the slide rail 322. The pitch of the upper threaded section 3231 is three times the pitch of the lower threaded section 3232. That is, when the slider 324 moves to the upper threaded section 3231, the displacement speed is three times that of the slider in the lower threaded section 3232. This enables rapid approach to the material, improves stamping efficiency, stamps the material at low speed, reduces the instantaneous impact force on the cutting edge, and reduces micro-chipping.

[0033] like Figure 5 As shown, the feedback mechanism 33 also includes a torque motor 332, a gear rod 333, and a gear ring 335. The torque motor 332 and the adjustable damping rod 334 are both fixedly connected to the side frame 331. The torque motor 332 is connected to the electrical control cabinet 2 via an electrical signal. The output end of the torque motor 332 is fixedly connected to the gear rod 333. The gear rod 333 meshes with the tooth surface of the gear ring 335. The gear ring 335 is rotatably connected to the adjustable damping rod 334.

[0034] Depending on the type of steel, the operator sends a specified electrical signal to the torque motor 332 through the control cabinet 2. The torque motor 332 outputs a fixed-axis torque to the gear rod 333, which rotates around its axis. Through the meshing of the gear rod 333 and the gear ring 335, the gear ring 335 rotates to adjust the damping magnitude of the adjustable damping rod 334.

[0035] like Figure 6 , Figure 7 As shown, the tool mechanism 35 also includes an internally cooled tool 352, a liquid pump 353, and a coolant cylinder 354. The internally cooled tool 352 is provided in several groups, and the several groups of internally cooled tools 352 are linearly and evenly distributed along the substrate 351. The internally cooled tool 352, the liquid pump 353, and the coolant cylinder 354 are all fixedly connected to the substrate 351. The internally cooled tool 352 is provided with a loop-shaped flow channel 3521, which is located inside the internally cooled tool 352. The liquid pump 353 is connected to the loop-shaped flow channel 3521 and the coolant cylinder 354 through pipes. The liquid pump 353 is connected to the electrical control cabinet 2 through electrical signals.

[0036] The slider 324 moves up and down along the slide rail 322, driving the tool mechanism 35 to perform continuous die stamping on the transported metal sheet raw material. The electrical control cabinet 2 sends an electrical signal to the liquid pump 353, which drives the medium to circulate through the pipe in the loop channel 3521 and the coolant cylinder 354 to circulate and cool the tool, effectively controlling the working temperature of the cutting edge and preventing hardness reduction and thermal fatigue wear caused by excessive temperature rise.

[0037] like Figure 6 As shown, the tool mechanism 35 also includes an oil injector 355, an oil pump 356, an oil reservoir 357, an air jet nozzle 358, and a high-pressure air pump 359. There are two sets of air jet nozzles 358, which are located on both sides of the oil injector 355. The oil injector 355, oil pump 356, oil reservoir 357, air jet nozzle 358, and high-pressure air pump 359 are all fixedly connected to the base plate 351. The oil pump 356 is connected to the oil injector 355 and the oil reservoir 357 through pipes. The air jet nozzle 358 is connected to the high-pressure air pump 359 through pipes. The oil pump 356 and the high-pressure air pump 359 are both connected to the electrical control cabinet 2 through electrical signals.

[0038] When the cutting tool mechanism 35 performs continuous die stamping operation on the transported metal sheet raw material, the electrical control cabinet 2 sends an electrical signal to the oil pump 356 and the high-pressure air pump 359. The oil pump 356 sprays the lubricating oil in the oil storage tank 357 from the oil nozzle 355. The high-pressure air pump 359 sprays high-pressure gas through the air nozzles 358 located on both sides of the oil nozzle 355. The high-pressure gas impacts the lubricating oil and forms a lubricating oil film between the cutting edge and the metal sheet raw material, which reduces the rigid collision between the cutting edge and the metal sheet and effectively reduces the wear of the cutting edge.

[0039] like Figure 8 As shown, the bottom mold mechanism 4 also includes a guide rail slide 42 and a discharge cylinder 43. The guide rail slide 42 and the discharge cylinder 43 are both fixedly connected to the machine tool base 41. The discharge cylinder 43 is located on the machine tool base 41 at the end away from the feeder 1.

[0040] The feeding machine 1 transports metal sheet raw materials to the guide rail slide table 42. The metal sheet raw materials slide down the material cylinder 43 on the guide rail slide table 42. The cutting tool mechanism 35 moves up and down and back and forth to perform continuous die stamping operation on the transported metal sheet raw materials.

[0041] The working principle of this invention: The feeding machine 1 transports metal sheet raw material to the bottom die mechanism 4. The operation control cabinet 2 sends an electrical signal to the punching mechanism 3. The drive mechanism 32 drives the cutting tool mechanism 35 to reciprocate downward through the slider 324. The cutting tool mechanism 35 performs continuous die punching operation on the transported metal sheet raw material. During punching, the servo motor 321 outputs fixed-axis torque to the segmented screw 323. The segmented screw 323 rotates around its axis, passing through the upper threaded section 3231, the lower threaded section 3232, and the internal threaded hole 3. In the 241-section threaded connection, when the rotational speed of the segmented screw 323 around its axis is constant, the pitch of the upper threaded section 3231 and the lower threaded section 3232 determines the displacement speed of the slider 324 along the slide rail 322. The pitch of the upper threaded section 3231 is three times that of the lower threaded section 3232. That is, when the slider 324 is displaced by the upper threaded section 3231, its displacement speed is three times that of the slider in the lower threaded section 3232. This allows for rapid material approach, improving stamping efficiency, low-speed material stamping, reducing the instantaneous impact force on the cutting edge, and minimizing micro-chipping. Simultaneously improving the cross-sectional quality, the tool mechanism 35 descends to the end away from the servo motor 321, and the pressure plate 3242 contacts the adjustable damping rod 334. The operator sends a specified electrical signal to the feedback mechanism 33 through the control cabinet 2, adjusting the damping of the adjustable damping rod 334 according to the stiffness of different metal sheet types. When stamping high-stiffness metal sheets, the damping of the adjustable damping rod 334 needs to be increased to reduce the rigid collision between the cutting edge and the high-stiffness metal sheet, reduce the instantaneous impact force on the cutting edge, and reduce micro-chipping. When stamping low-stiffness metal sheets... The adjustable damping rod 334 is reduced to increase the instantaneous collision force between the cutting edge and the low-rigidity metal sheet, thus preventing the cutting edge from slowly pressing the low-rigidity metal sheet and causing excessive shrinkage deformation of the metal sheet due to extrusion. The tool mechanism 35 has a channel inside to circulate liquid cooling for the tool, effectively controlling the working temperature of the cutting edge and preventing hardness reduction and thermal fatigue wear caused by excessive temperature rise. At the same time, a lubricating oil film is formed between the cutting edge and the metal sheet material to reduce the rigid collision between the cutting edge and the metal sheet, effectively reducing the wear of the cutting edge.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
