Description

Technical Field

[0001] The present invention relates to the technical field of stamping metal dies for automotive parts, and specifically to a stamping die with an oil cylinder flat-cut waste mechanism. Background Technique

[0002] As an important auxiliary processing equipment in the production process of automotive parts, a stamping metal die can stamp metal sheets into various complex shapes, meet the requirements of the body appearance design, and at the same time ensure the accuracy and surface quality of the parts.

[0003] During the process of stamping and processing the metal sheet of automotive parts using a die, in order to ensure product quality, facilitate subsequent processing, and improve material utilization rate, etc., a flat-cut waste mechanism is required to perform cutting operations on the excess waste after stamping and forming.

[0004] As a core functional component on the stamping metal die, during the process of removing waste from the stamped workpiece, in order to avoid deformation of the waste during cutting, especially for some relatively thin or soft-textured metal materials, and to avoid bending, twisting and other deformation situations of the cutting waste, a support component for supporting the waste is provided on one side of the waste. However, the support state of the support component is relatively fixed and cannot control the support effect in real time according to the actual cutting state. There are often situations where the support force is small and it is difficult to ensure effective support during the cutting process, and the support force is large and the waste in the uncut state is bent and deformed, affecting precise cutting. Therefore, we propose a stamping die with an oil cylinder flat-cut waste mechanism. Summary of the Invention

[0005] The purpose of the present invention is to provide a stamping die with an oil cylinder flat-cut waste mechanism to solve the problems raised in the above background technique.

It also includes:

[0008] A waste flat-cutting assembly, which is arranged between the lower die base and the upper die base for cutting the excess product waste after stamping;

[0009] An oil cylinder driving assembly, which is arranged between the lower die base and the upper die base for driving the waste flat-cutting assembly;

[0010] A support component is arranged on one side of the female die for supporting the waste cutting position;

[0011] And a pushing component arranged on one side of the female die for pushing the support component. A transmission component for transmitting the pushing component is arranged on the oil cylinder driving component.

[0012] Preferably, the waste flat cutting component includes a connecting rod. One end of the connecting rod is fixedly connected with a mounting seat through a mounting sleeve. A cutter for cutting the waste after stamping is detachably mounted on the mounting seat through bolts;

[0013] It should be noted here that: during the waste cutting process, the oil cylinder body drives the connecting rod and the mounting sleeve to move towards the workpiece. During the movement, the cutter on the mounting seat moves synchronously. Through the movement of the cutter and its contact with the position of the workpiece waste, the waste is flat cut.

[0014] Preferably, the oil cylinder driving component includes an oil cylinder body. The oil cylinder body is fixedly connected with the upper die base through a fixing rod. The connecting rod is fixedly connected with the output end of the oil cylinder body;

[0015] It should be noted here that: through the oil cylinder body, it is convenient to drive the connecting rod.

[0016] Preferably, the support component includes a push plate. A telescopic component for assisting the telescopic connection of the push plate is arranged between the female die and the push plate. A support plate for abutting against the back position of the waste is arranged on one side of the push plate. A first elastic component for elastic extrusion is arranged between the push plate and the support plate. A grinding component for grinding the end of the waste cutting position of the product is arranged on the support plate. A magnetic block for magnetic adsorption with the cutter is embedded on the side of the support plate abutting against the waste;

[0017] It should be noted here that: through transmission, the push plate is pushed towards the blanking position of the workpiece. During the pushing process, the support plate abuts against the back of the blanking position of the workpiece to support the flat blanking position of the workpiece. And during the support process, the push plate will move towards the blanking position of the workpiece synchronously with the forward movement of the cutter. Through the movement of the push plate and the abutting action between the support plate and the blanking position of the workpiece, the push plate moves towards the support plate and contracts. During the contraction movement, the second sliding rod is forced to slide on the second sleeve and the first extrusion spring is continuously deformed to increase the elastic force. Through the continuous increase of the elastic force of the first extrusion spring, the support pressure during the flat cutting support of the workpiece is synchronously increased, fully ensuring the support effect on the blanking position of the workpiece during the flat blanking process.

[0018] Preferably, the first elastic component includes multiple groups of first sleeves fixed on the support plate. A first sliding rod is slidably connected to the first sleeve. One end of the first sliding rod is fixed to the push plate, and a first compression spring is sleeved outside the first sleeve.

[0019] It should be noted here that during the support process, the push plate will move towards the workpiece blanking position synchronously with the forward movement of the cutting tool. Through the movement of the push plate and the abutting effect between the support plate and the workpiece blanking position, the push plate moves towards the support plate and contracts. During the contraction movement, the second sliding rod is pushed to slide on the second sleeve, and the first compression spring is continuously deformed to increase the elastic force. Through the continuous increase of the elastic force of the first compression spring, the support pressure during the flat cutting support of the workpiece is synchronously increased, fully ensuring the support effect on the workpiece blanking position during the flat cutting process.

[0020] Preferably, the telescopic component includes multiple groups of second sleeves fixed on one side of the concave die. A second sliding rod is slidably connected to the second sleeve. One end of the second sliding rod is fixed to the push plate.

One end of the connecting rod away from the installation shaft is rotatably connected to a slider through a pin shaft, and the slider is slidably connected to one side of the push plate.

[0023] It should be noted here that through the transmission component, the installation shaft is stressed to rotate on the mounting frame. During the rotation of the installation shaft, the connecting rod is driven to rotate 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 blanking position. During the pushing process, the support plate abuts against the back of the workpiece blanking position to support the flat cutting position of the workpiece.

[0024] Preferably, the transmission component includes a gear fixed at the end of the installation shaft. Two racks are respectively fixedly connected to the installation sleeve through two L-shaped frames. The two racks are respectively meshed with the two gears.

[0025] It should be noted here that during the flat cutting process of the waste material, through the movement of the installation sleeve and the connection of the L-shaped frame, the racks are driven to move synchronously. Through the movement of the racks and the meshing transmission between the racks and the gears, the installation shaft is stressed to rotate on the mounting frame.

[0026] Preferably, the grinding assembly includes a mounting groove formed in the upper end of the support plate. A grinding knife is connected to the mounting groove through a second elastic component. A grinding inclined surface for obliquely grinding the cutting end face is formed on the grinding knife.

[0027] It should be noted here that after the flat cutting is completed, due to the magnetic force between the magnet on the support plate and the cutting knife, when the cutting knife returns, it pulls the support plate away from the female die. During the movement, through the second elastic component, the grinding inclined surface on the grinding knife is pushed to abut against the end of the workpiece after the blanking cutting. The end of the blanking is ground through the friction generated during the abutting process, and the burrs existing after the flat cutting are eliminated through the grinding process, ensuring the processing quality of the workpiece.

[0028] Preferably, the second elastic component includes a third sleeve fixed inside the mounting groove. A third sliding rod is slidably connected to the third sleeve. One end of the third sliding rod is fixed to the end of the grinding knife. A second compression spring is sleeved outside the third sleeve, and the second compression spring abuts against the inner wall of the mounting groove and the grinding knife respectively.

[0029] It should be noted here that through the third sleeve and the third sliding rod, it is convenient to assist the telescopic connection of the grinding knife, and through the second compression spring, it is convenient to push the retracted grinding knife.

[0052] It should be noted here that when using the die to perform stamping operation on the metal plate of automobile parts, after the operation is completed, the waste flat cutting assembly is used to perform flat cutting treatment on the workpiece waste. During the treatment process, through the mutual cooperation of the support assembly, the pushing assembly and the transmission assembly, the supporting force at the workpiece blanking cutting position can be adaptively adjusted according to the actual flat cutting state, while ensuring the supporting effect, avoiding deformation at the blanking cutting position caused by excessive initial supporting force, and further ensuring the quality of blanking cutting of the stamping workpiece, so as to realize the precision stamping processing operation of the die on the metal plate of automobile parts.

Through the movement of the cutter 204 and its contact with the position of the workpiece waste, a flat cutting operation is performed on the waste.

[0058] It should be noted here that through transmission, the push plate 401 is pushed towards the blanking position of the workpiece. During the pushing process, the support plate 402 contacts the back of the blanking position of the workpiece to support the flat blanking position of the workpiece. And during the support process, the push plate 401 will move towards the blanking position of the workpiece synchronously with the forward movement of the cutter 204.

[0062] It should be noted here that through the second sleeve 601 and the second sliding rod 602, it is convenient for the pushing plate 401 to perform telescopic movement after being stressed.

[0067] Embodiment 2

[0068] Please refer to Figures 1 - 8 , in this embodiment, a further description is made on Embodiment 1. The grinding assembly in FIG. 6 includes a mounting groove 901 formed at the upper end of the support plate 402. A grinding knife 902 is connected to the mounting groove 901 through a second elastic component. A grinding inclined surface 903 for obliquely grinding the cutting end face is formed on the grinding knife 902;

[0069] It should be noted here that after the flat cutting is completed, through the magnetic force between the magnet on the support plate 402 and the cutting knife 204, when the cutting knife 204 moves in the reset direction, it pulls the support plate 402 to move away from the female die 104. During the movement, through the second elastic component, the grinding inclined surface 903 on the grinding knife 902 is pushed to abut against the end of the workpiece after the blanking cutting. Through the friction generated during the abutting process, the end of the blanking is ground, and the burrs existing after the flat cutting are eliminated through the grinding process to ensure the processing quality of the workpiece (see Figure 8 );

[0070] It should be noted here that when the support plate 402 is reset later, the grinding inclined surface 903 abuts against the end of the workpiece after the blanking cutting, causing the grinding knife 902 to move inward and contract towards the inside of the mounting groove 901. Through the contraction movement, the grinding knife 902 is 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 sliding rod 1002 is slidably connected to the third sleeve 1001. One end of the third sliding rod 1002 is fixed to the end of the grinding knife 902. A second compression spring 1003 is sleeved outside the third sleeve 1001, and the second compression spring 1003 abuts against the inner wall of the mounting groove 901 and the grinding knife 902 respectively;

[0072] It should be noted here that through the third sleeve 1001 and the third sliding rod 1002, it is convenient to assist the telescopic connection of the grinding knife 902, and through the second compression spring 1003, it is convenient to push and squeeze the grinding knife 902 after the contraction movement.

[0073] In this solution: a stamping die with an oil cylinder flat cutting waste mechanism includes the following steps:

[0074] During the process of the die stamping the metal plate, the workpiece is positioned and placed on the upper surface of the female die 104. After the placement is completed, the driving component drives the upper die base 102 to move downward. During the downward movement of the upper die base 102, the pressure plate 106 is driven to move downward and abut against the workpiece through the fixed seat 105 and the pressure spring 107. During the abutting process, through the interaction between the female die 104 and the pressure plate 106, the stamping process of the workpiece is completed;

[0075] After stamping the workpiece, the redundant waste on the workpiece is removed by the waste flat cutting assembly. Before the cutting operation, since the support plate 402 on the support assembly is not pushed, at this time, the support plate 402 does not abut against the back of the waste position on the workpiece, avoiding deformation of the waste position on the workpiece under the action of abutting support, which affects the subsequent precise cutting operation. During the waste cutting process, the oil cylinder body 301 drives the connecting rod 201 and the mounting sleeve 202 to move towards the workpiece. During the movement, the cutting tool 204 on the mounting seat 203 moves synchronously. Through the movement of the cutting tool 204 and abutting against the waste position of the workpiece, the waste is flat cut. During the waste flat cutting process, through the movement of the mounting sleeve 202 and the connection of the L-shaped frame 803, the rack 802 moves 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 forced to rotate on the mounting frame 701. During the rotation of the mounting shaft 702, the connecting rod 703 rotates 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 cutting position of the workpiece. During the pushing process, the support plate 402 abuts against the back of the cutting position of the workpiece to support the flat cutting position of the workpiece. And during the support process, the push plate 401 moves towards the cutting position of the workpiece synchronously with the forward movement of the cutting tool 204. Through the movement of the push plate 401 and the abutting action between the support plate 402 and the cutting position of the workpiece, the push plate 401 moves towards the support plate 402 in a shrinking motion. During the shrinking motion, the second slide rod 602 is forced to slide on the second sleeve 601, and the first compression spring 503 is continuously deformed to increase the elastic force. Through the continuous increase of the elastic force of the first compression spring 503, the support pressure during the flat cutting support of the workpiece increases synchronously, fully ensuring the support effect on the cutting position of the workpiece during the flat cutting process, further avoiding deformation of the cutting waste position due to insufficient support force during the cutting process, improving the effect of waste flat cutting. And during the support process, when the mounting seat 203 and the cutting tool 204 move and perform flat cutting operations at a greater speed, through transmission, the pushing speed of the push plate 401 is increased, and further the pushing speed of the first compression spring 503 on the first elastic component is increased. Due to the mass of the first compression spring 503 itself, when the pushing is accelerated, each particle of the first compression spring 503 will generate an acceleration a,According to Newton's second law, the externally applied force needs to overcome the spring elastic force and the inertial force of the spring itself at the same time: F_ext = kx + ma, where m is the mass of the part of the spring participating in the movement, a is the acceleration. When pushing quickly, the acceleration a is greater (because the rate of change of velocity dv / dt is higher), resulting in a significant increase in F_ext. At this time, the force felt by the support plate 402 includes the inertial force, rather than simply the spring elastic force kx. Therefore, when the movement speed of the cutting tool 204 increases, the supporting force of the support plate 402 on the workpiece blanking and cutting position is synchronously increased to adaptively match the supporting effect;

[0076] After the flat cutting is completed, through the magnetic force between the magnet on the support plate 402 and the cutting tool 204, when the cutting tool 204 moves back, it pulls the support plate 402 away from the concave die 104. During the movement, through the second elastic component, the grinding inclined surface 903 on the grinding tool 902 is pushed to abut against the end of the workpiece after blanking and cutting. The end of the blanking is ground through the friction generated during the abutting process, and the burrs existing after the flat cutting are eliminated through the grinding process to ensure the processing quality of the workpiece.
