Description

Technical Field

[0001] This invention relates to the field of stamping metal dies for automotive parts, specifically to stamping dies with a hydraulic cylinder-based waste-cutting mechanism. Background Technology

[0002] As an important auxiliary processing equipment in the production of automotive parts, stamping metal dies can stamp metal sheets into various complex shapes to meet the requirements of vehicle body appearance design, while ensuring the precision and surface quality of the parts.

[0003] In the process of stamping metal sheets for automotive parts using molds, in order to ensure product quality, facilitate subsequent processing, and improve material utilization, a scrap trimming mechanism is needed to remove excess scrap after stamping.

[0004] As a core functional component of stamping metal dies, the scrap cutting mechanism is used to remove scrap from stamped workpieces. To prevent deformation of the scrap during the cutting process, especially for thinner or softer metal materials, and to avoid bending or twisting of the scrap, a support component is set on one side of the scrap. However, the support state of the support component is relatively fixed, and the support effect cannot be controlled in real time according to the actual cutting state. Often, the support force is too small to ensure effective support during the cutting process, while the support force is too large, causing the scrap in the uncut state to bend and deform, affecting the accuracy of cutting. Therefore, we propose a stamping die with a hydraulic cylinder scrap cutting mechanism. Summary of the Invention

[0005] The purpose of this invention is to provide a stamping die with a hydraulic cylinder for cutting waste material, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a stamping die with a hydraulic cylinder for cutting waste material, comprising:

[0007] The system includes a lower mold base and an upper mold base, with a driving component for lifting and lowering the upper mold base provided between them. Guide pillars for guiding the die are fixed at the four corners of the lower and upper mold bases. A die cavity is fixed on the lower mold base, and a fixed base is fixed at the bottom of the upper mold base. A pressure plate is connected to the lower end of the fixed base via a pressure spring. The system also includes:

[0008] The waste cutting component is set between the lower die base and the upper die base to remove excess product waste after stamping;

[0009] The hydraulic cylinder drive assembly is located between the lower die base and the upper die base and is used to drive the waste material flat cutting assembly;

[0010] A support component, located on one side of the die cavity, is used to support the waste material cutting area;

[0011] In addition, a pushing component for pushing the support component is provided on one side of the die, and a transmission component for driving the pushing component is provided on the cylinder drive component.

[0012] Preferably, the waste cutting assembly includes a connecting rod, one end of which is fixedly connected to a mounting base via a mounting sleeve, and a cutter for cutting off the waste after stamping is detachably mounted on the mounting base via bolts;

[0013] It should be noted here that during the waste removal process, the connecting rod and mounting sleeve are driven by the hydraulic cylinder to move toward the workpiece. During the movement, the cutter on the mounting base moves synchronously. The movement of the cutter and its contact with the position of the waste material on the workpiece result in a flat cutting operation on the waste material.

[0014] Preferably, the hydraulic cylinder drive assembly includes a hydraulic cylinder body, which is connected and fixed to the upper mold base by a fixing rod, and the connecting rod is connected and fixed to the output end of the hydraulic cylinder body;

[0015] It should be noted here that the connecting rod can be easily driven through the hydraulic cylinder body.

[0016] Preferably, the support assembly includes a push plate, a telescopic assembly for assisting the telescopic connection of the push plate is provided between the die and the push plate, a support plate for abutting against the back of the waste material is provided on one side of the push plate, a first elastic assembly for elastic extrusion is provided between the push plate and the support plate, a grinding assembly for grinding the end of the waste material cutting position is provided on the support plate, and a magnetic block for magnetic attraction with the cutter is embedded on the side of the support plate that abuts against the waste material.

[0017] It should be noted here that: through transmission, the push plate is pushed towards the workpiece cutting position. During the pushing process, the support plate abuts against the back of the workpiece cutting position, supporting the workpiece at the flat cutting position. During the support process, the push plate moves towards the workpiece cutting position synchronously with the forward movement of the cutter. Through the movement of the push plate and the abutment between the support plate and the workpiece cutting position, the push plate retracts towards the support plate. During the retraction movement, the second slide rod is pushed and slides on the second sleeve, causing the first compression spring to continuously deform and increase its elastic force. The continuous increase in the elastic force of the first compression spring increases the supporting pressure during the flat cutting support process, fully ensuring the support effect on the workpiece cutting position during the flat cutting process.

[0018] Preferably, the first elastic component includes multiple sets of first sleeves fixed to the support plate, a first slide rod slidably connected to the first sleeve, one end of the first slide rod being fixed to the push plate, and a first compression spring being sleeved on the outside of the first sleeve;

[0019] It should be noted that during the support process, the push plate moves synchronously towards the workpiece cutting position as the cutter advances. Through the movement of the push plate and the resistance between the support plate and the workpiece cutting position, the push plate retracts towards the support plate. During the retraction, the second slide rod is pushed to slide on the second sleeve, causing the first compression spring to continuously deform and increase its elastic force. The continuous increase in the elastic force of the first compression spring increases the support pressure during the flat cutting support process, thus fully ensuring the support effect on the workpiece cutting position during the flat cutting process.

[0020] Preferably, the telescopic assembly includes multiple sets of second sleeves fixed to one side of the die, with a second slide rod slidably connected to the second sleeve, and one end of the second slide rod fixed to the push plate;

[0021] It should be noted here that the second sleeve and the second slide rod facilitate the extension and retraction of the push plate after it is subjected to force.

[0022] Preferably, the pushing assembly includes two sets of mounting brackets fixed to one side of the die cavity, with mounting shafts rotatably connected to the two sets of mounting brackets. Two sets of connecting rods symmetrically arranged are fixed on the mounting shafts. The end of each connecting rod away from the mounting shaft is rotatably connected to a slider via a pin. The slider is slidably connected to one side of the push plate.

[0023] It should be noted here that: through the transmission component, the mounting shaft is subjected to force and rotates on the mounting bracket. During the rotation of the mounting shaft, the connecting rod rotates synchronously. During the rotation of the connecting rod, through the transmission of the connecting rod and the connection of the slider, the push plate is pushed towards the workpiece cutting position. During the pushing process, the support plate abuts against the back of the workpiece cutting position, thus supporting the workpiece at the flat cutting position.

[0024] Preferably, the transmission assembly includes a gear fixed to the end of the mounting shaft, and two sets of racks are fixedly connected to the mounting sleeve by two sets of L-shaped brackets, and the two sets of racks are respectively meshed with the two sets of gears.

[0025] It should be noted here that during the waste material cutting process, the movement of the mounting sleeve and the connection of the L-shaped frame drive the rack to move synchronously. Through the movement of the rack and the meshing transmission between the rack and the gear, the mounting shaft is subjected to force and rotates on the mounting frame.

[0026] Preferably, the grinding assembly includes a mounting groove formed on the upper end of the support plate, and a grinding blade is connected to the mounting groove via a second elastic component. The grinding blade has a grinding bevel for grinding at an angle to the cutting end face.

[0027] It should be noted that after the flat cut is completed, the magnetic force between the magnetic block on the support plate and the cutter causes the cutter to move away from the die during its reset movement. During this movement, the second elastic component pushes the grinding bevel on the grinding blade to abut against the end of the workpiece after it has been cut. The friction generated during the abutment process grinds the end of the cut material, eliminating the burrs present after the flat cut and ensuring the processing quality of the workpiece.

[0028] Preferably, the second elastic component includes a third sleeve fixed inside the mounting groove, a third slide rod slidably connected to the third sleeve, one end of the third slide rod being fixed to the end of the grinding tool, and a second compression spring being sleeved on the outside of the third sleeve, the second compression spring being respectively abutted against the inner wall of the mounting groove and the grinding tool;

[0029] It should be noted here that the third sleeve and the third slide rod facilitate the retractable connection of the grinding tool, and the second compression spring facilitates the compression and pushing of the grinding tool after the retraction movement.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] This invention uses a mold to stamp metal sheets for automotive parts. After the stamping is completed, the scrap is cut off by a scrap cutting component. During the process, the support component, the pushing component, and the transmission component work together to adaptively adjust the support force at the cutting position of the workpiece according to the actual cutting state. This ensures the support effect while avoiding deformation at the cutting position due to excessive support force in the early stage, thus further ensuring the quality of the stamped workpiece cutting and realizing the precision stamping operation of the mold on the metal sheets of automotive parts.

Detailed Implementation

[0041] 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.

[0042] Example 1

[0043] Please see Figures 1-8 The stamping die shown in the figure, which has a hydraulic cylinder for cutting waste, includes:

[0044] The lower mold base 101 and the upper mold base 102 are provided with a driving component for lifting the upper mold base 102 between the lower mold base 101 and the upper mold base 102. Guide pillars 103 for guiding the mold are installed and fixed at the four corners between the lower mold base 101 and the upper mold base 102. A die 104 is fixed on the lower mold base 101. A fixed seat 105 is fixed at the bottom of the upper mold base 102. The lower end of the fixed seat 105 is connected to a pressure plate 106 through a pressure spring 107.

[0045] It should be noted here that during the stamping operation of the die on the metal sheet, the workpiece is positioned on the upper surface of the die 104. After placement, the upper die base 102 is driven to descend by the drive component. During the descent of the upper die base 102, the pressure plate 106 is driven to descend by the fixed base 105 and the pressure spring 107 and comes into contact with the workpiece. During the contact process, the stamping process of the workpiece is completed by the interaction between the die 104 and the pressure plate 106.

[0046] It should be noted here that the lower die holder 101, upper die holder 102, driving component, guide pillar 103, die cavity 104, fixed base 105, pressure plate 106 and pressure spring 107 are conventional technical components in stamping dies. Their working principle and operation method are considered prior art in this application and will not be elaborated here.

[0047] Also includes:

[0048] A waste cutting component is disposed between the lower die base 101 and the upper die base 102 for removing excess product waste after stamping.

[0049] A hydraulic cylinder drive assembly is located between the lower die base 101 and the upper die base 102 for driving the waste material flat cutting assembly;

[0050] A support component is provided on one side of the die cavity 104 to support the waste material cutting area;

[0051] In addition, a pushing component for pushing the support component is provided on one side of the die 104, and a transmission component for driving the pushing component is provided on the cylinder drive component.

[0052] It should be noted that: the stamping operation of automotive parts metal sheets is performed using a mold. After the operation is completed, the scrap is cut off by a scrap cutting component. During the process, the support component, push component, and transmission component work together to adaptively adjust the support force at the cutting position of the workpiece according to the actual cutting state. This ensures the support effect while avoiding deformation at the cutting position due to excessive support force in the early stage, further ensuring the quality of the cutting of the stamped workpiece and realizing the precision stamping operation of automotive parts metal sheets using the mold.

[0053] Preferably, the waste cutting assembly includes a connecting rod 201, one end of which is fixedly connected to a mounting base 203 via a mounting sleeve 202, and a cutter 204 for cutting off the waste after stamping is detachably mounted on the mounting base 203 by bolts.

[0054] It should be noted that during the waste removal process, the connecting rod 201 and the mounting sleeve 202 are driven by the cylinder body 301 to move toward the workpiece. During the movement, the cutter 204 on the mounting seat 203 moves synchronously. Through the movement of the cutter 204 and its contact with the position of the workpiece waste, the waste is cut flat.

[0055] Preferably, the hydraulic cylinder drive assembly includes a hydraulic cylinder body 301, which is connected and fixed to the upper mold base 102 by a fixing rod 302, and a connecting rod 201 is connected and fixed to the output end of the hydraulic cylinder body 301.

[0056] It should be noted here that the connecting rod 201 can be easily driven by the cylinder body 301.

[0057] Preferably, the support assembly includes a push plate 401, a telescopic assembly for assisting the telescopic connection of the push plate 401 is provided between the die 104 and the push plate 401, a support plate 402 for abutting against the back of the waste material is provided on one side of the push plate 401, a first elastic assembly for elastic extrusion is provided between the push plate 401 and the support plate 402, a grinding assembly for grinding the end of the waste material cutting position is provided on the support plate 402, and a magnetic block for magnetic attraction with the cutter 204 is embedded on the side of the support plate 402 that abuts against the waste material.

[0058] It should be noted that: through transmission, the push plate 401 is pushed towards the workpiece cutting position. During the pushing process, the support plate 402 abuts against the back of the workpiece cutting position, supporting the workpiece at the flat cutting position. During the support process, the push plate 401 moves towards the workpiece cutting position synchronously with the forward movement of the cutter 204. Through the movement of the push plate 401 and the abutment between the support plate 402 and the workpiece cutting position, the push plate 401 retracts towards the support plate 402. During the retraction process, the second slide rod 602 is pushed and slides on the second sleeve 601, causing the first compression spring 503 to continuously deform and increase its elastic force. The continuous increase in the elastic force of the first compression spring 503 increases the supporting pressure during the flat cutting support process, thus fully ensuring the support effect on the workpiece cutting position during the flat cutting process.

[0059] Preferably, the first elastic component includes multiple sets of first sleeves 501 fixed on the support plate 402, a first slide rod 502 slidably connected to the first sleeve 501, one end of the first slide rod 502 being fixed to the push plate 401, and a first compression spring 503 being sleeved on the outer side of the first sleeve 501.

[0060] It should be noted that during the support process, the push plate 401 moves synchronously toward the workpiece cutting position as the cutter 204 moves forward. Through the movement of the push plate 401 and the resistance between the support plate 402 and the workpiece cutting position, the push plate 401 moves toward the support plate 402 in a contraction motion. During the contraction motion, the second slide rod 602 is pushed to slide on the second sleeve 601 and the first compression spring 503 continuously deforms and increases its elastic force. The continuous increase in the elastic force of the first compression spring 503 increases the support pressure during the flat cutting support process of the workpiece, thus fully ensuring the support effect on the workpiece cutting position during the flat cutting process.

[0061] Preferably, the telescopic assembly includes multiple sets of second sleeves 601 fixed to one side of the die 104, and a second slide rod 602 is slidably connected to the second sleeve 601. One end of the second slide rod 602 is fixed to the push plate 401.

[0062] It should be noted here that the second sleeve 601 and the second slide rod 602 facilitate the extension and retraction of the push plate 401 after it is subjected to force.

[0063] Preferably, the pushing component includes two sets of mounting brackets 701 fixed to one side of the die 104. The two sets of mounting brackets 701 are rotatably connected to the mounting shafts 702. Two sets of connecting rods 703 are fixed on the mounting shafts 702. The end of the connecting rod 703 away from the mounting shaft 702 is rotatably connected to the slider 704 through the pin. The slider 704 is slidably connected to one side of the push plate 401.

[0064] It should be noted here that: through the transmission component, the mounting shaft 702 is subjected to force and rotates on the mounting bracket 701. During the rotation of the mounting shaft 702, the connecting rod 703 is driven to rotate synchronously. During the rotation of the connecting rod 703, through the transmission of the connecting rod 703 and the connection of the slider 704, the push plate 401 is pushed towards the workpiece cutting position. During the pushing process, the support plate 402 abuts against the back of the workpiece cutting position, supporting the workpiece at the flat cutting position.

[0065] Preferably, the transmission assembly includes a gear 801 fixed to the end of the mounting shaft 702, and two sets of racks 802 are fixedly connected to the mounting sleeve 202 by two sets of L-shaped brackets 803 respectively, and the two sets of racks 802 are respectively meshed with the two sets of gears 801.

[0066] It should be noted that during the waste material cutting process, the movement of the mounting sleeve 202 and the connection of the L-shaped frame 803 drive the rack 802 to move synchronously. Through the movement of the rack 802 and the meshing transmission between the rack 802 and the gear 801, the mounting shaft 702 is subjected to force and rotates on the mounting frame 701.

[0067] Example 2

[0068] Please see Figures 1-8 This embodiment further illustrates embodiment 1. The grinding assembly in Figure 6 includes a mounting groove 901 opened on the upper end of the support plate 402. A grinding blade 902 is connected to the mounting groove 901 through a second elastic component. The grinding blade 902 is provided with a grinding inclined surface 903 for grinding at an angle to the cutting end face.

[0069] It should be noted here that after the flat cut is completed, the magnetic force between the magnetic block on the support plate 402 and the cutter 204 causes the cutter 204 to move away from the die 104 during its reset movement. During this movement, the second elastic component pushes the grinding bevel 903 on the grinding blade 902 to abut against the cut end of the workpiece. The friction generated during this abutment process grinds the cut end, eliminating burrs after the flat cut and ensuring the processing quality of the workpiece (see [reference]). Figure 8 );

[0070] It is worth noting here that during the subsequent resetting process of the support plate 402, the grinding bevel 903 abuts against the end of the cut part, causing the grinding blade 902 to retract towards the interior of the mounting groove 901. Through this retraction, the grinding blade 902 is placed in a compressed state (see...). Figure 7 ).

[0071] Preferably, the second elastic component includes a third sleeve 1001 fixed inside the mounting groove 901, a third slide rod 1002 slidably connected to the third sleeve 1001, one end of the third slide rod 1002 being fixed to the end of the grinding tool 902, and a second compression spring 1003 sleeved on the outside of the third sleeve 1001, the second compression spring 1003 being respectively abutted against the inner wall of the mounting groove 901 and the grinding tool 902;

[0072] It should be noted that the third sleeve 1001 and the third slide rod 1002 facilitate the telescopic connection of the grinding tool 902, and the second compression spring 1003 facilitates the compression and pushing of the grinding tool 902 after the retraction movement.

[0073] In this solution, the stamping die with a hydraulic cylinder-based waste-cutting mechanism includes the following steps:

[0074] During the stamping operation of the die on the metal sheet, the workpiece is positioned on the upper surface of the die 104. After placement, the upper die base 102 is driven to descend by the drive component. During the descent of the upper die base 102, the pressure plate 106 is driven to descend by the fixed base 105 and the pressure spring 107 and comes into contact with the workpiece. During the contact process, the stamping process of the workpiece is completed by the interaction between the die 104 and the pressure plate 106.

[0075] After stamping the workpiece, the excess scrap is removed by the scrap cutting assembly. Before the cutting operation, the support plate 402 on the support assembly is not pushed, so it does not abut against the back of the scrap position on the workpiece. This prevents deformation of the scrap position on the workpiece due to the abutment support, which would affect the subsequent precise cutting operation. During the scrap removal process, the connecting rod 201 and the mounting sleeve 202 are driven by the cylinder body 301 to move towards the workpiece. During the movement, the cutter 204 on the mounting base 203 moves synchronously. The movement of the cutter 204 and its contact with the scrap on the workpiece... The workpiece is cut flat by adjusting the positions of the components. During the cutting process, the movement of the mounting sleeve 202 and the connection of the L-shaped frame 803 drive the rack 802 to move synchronously. Through the movement of the rack 802 and the meshing transmission between the rack 802 and the gear 801, the mounting shaft 702 rotates on the mounting frame 701. This rotation of the mounting shaft 702 drives the connecting rod 703 to rotate synchronously. During the rotation of the connecting rod 703, through the transmission of the connecting rod 703 and the connection of the slider 704, the push plate 401 is pushed towards the workpiece cutting position. The support plate 402 abuts against the back of the workpiece's cutting position, supporting the workpiece at the flat cutting position. During this support process, the push plate 401 moves synchronously towards the workpiece's cutting position as the cutter 204 advances. Through the movement of the push plate 401 and the abutment between the support plate 402 and the workpiece's cutting position, the push plate 401 retracts towards the support plate 402. During this retraction, the second slide rod 602 is pushed and slides on the second sleeve 601, causing the first compression spring 503 to continuously deform and increase its elastic force. The continuous increase in the elastic force of the first compression spring 503 facilitates the flat cutting support process of the workpiece. The supporting pressure increases synchronously, ensuring sufficient support for the workpiece cutting position during the flat cutting process. This further prevents deformation of the cutting waste position due to insufficient support during the cutting process, improving the flat cutting effect. Furthermore, during the supporting process, when the mounting base 203 and the cutter 204 move at a higher speed and perform flat cutting, the transmission increases the pushing speed of the push plate 401, further increasing the pushing speed of the first compression spring 503 on the first elastic component. Due to the mass of the first compression spring 503 itself, each mass point of the first compression spring 503 will generate an acceleration 'a' during accelerated pushing.According to Newton's second law, the external force must overcome both the spring force and the spring's own inertial force: Fexternal = kx + ma, where m is the mass of the spring's moving part and a is the acceleration. During rapid pushing, the acceleration a is greater (due to a higher rate of change of velocity dv / dt), leading to a significant increase in Fexternal. At this time, the force felt by the support plate 402 includes the inertial force, not just the simple spring force kx. Therefore, when the movement speed of the cutter 204 increases, the support force of the support plate 402 on the workpiece cutting position increases simultaneously, allowing the support effect to adaptively match.

[0076] After the flat cut is completed, the magnetic force between the magnetic block on the support plate 402 and the cutter 204 causes the cutter 204 to move away from the die 104 during its reset movement. During the movement, the second elastic component pushes the grinding bevel 903 on the grinding blade 902 to abut against the end of the workpiece after the material is cut. The friction generated during the abutment process grinds the end of the material, eliminating the burrs present after the flat cut and ensuring the processing quality of the workpiece.
