Description

Technical Field

[0001] The present invention relates to the technical field of stamping, and specifically to a continuous stamping and forming device and stamping method based on deformation suppression. Background Art

[0002] The stamping process currently occupies a crucial position in industrial production. Its core principle is to apply directional pressure to metal workpieces with the help of precision molds, enabling the workpieces to achieve controllable geometric reshaping within the plastic deformation range, thereby efficiently producing three-dimensional workpieces that meet the design blueprints. With its high efficiency, high precision, and excellent material utilization rate, this process has become a key manufacturing technology in fields such as automobile manufacturing, home appliance production, and aerospace component processing.

[0003] However, during the dynamic process of actual stamping operations, the deformation problem of workpieces has always been the core bottleneck restricting stamping accuracy. When the workpiece is accurately positioned on the lower die platform, the upper die will form an instantaneous impact contact with the workpiece when approaching at high speed. Especially when processing workpieces with extremely thin thicknesses, the surface area-to-volume ratio increases, and the local stiffness decreases significantly, resulting in unexpected wrinkles, corrugations, or local depressions at the front edge of the die contact.

[0004] An in-depth analysis of its causes reveals that existing stamping equipment generally uses a crank and connecting rod mechanism driven by a servo motor. Although it can meet the high-efficiency stamping rhythm, its uniform motion characteristics cause impact stress when the die contacts the workpiece, far exceeding the yield strength threshold of thin sheet workpieces. This impact effect will trigger the reflection and superposition of stress waves inside the workpiece, forming a dynamic load distribution similar to the "water hammer effect", ultimately causing local material instability and deformation. Summary of the Invention

[0005] The purpose of the present invention is to provide a continuous stamping and forming device and stamping method based on deformation suppression to solve the problems raised in the above background art.

After the driving rod group drives the upper stamping die to move to a predetermined position at a predetermined speed, the driving rod group can reduce the speed of driving the upper stamping die; A lower stamping die, arranged on the frame, and multiple groups of supporting parts are arranged on the side of the lower stamping die; A pressure application assembly, arranged on both sides of the frame, and a pressure application member adapted to the supporting parts is connected to the pressure application assembly; A connecting plate is connected to the upper stamping die, and the connecting plate cooperates with the pressure component and can be locked after the pressure component descends to a predetermined position.

[0007] As a further solution of the present invention: the driving cylinder body is fixedly mounted on the frame, and a first inner cylinder and a second inner cylinder are formed on the driving cylinder body, the first inner cylinder is arranged on the upper part of the second inner cylinder, and the circumferential diameter of the first inner cylinder is smaller than the circumferential diameter of the second inner cylinder.

[0008] As a further solution of the present invention: the driving rod group includes a connecting shaft that penetrates the driving cylinder body and is slidably arranged, one end of the connecting shaft is connected to the upper punching die, and the other end is connected to a first sealing plug, and the first sealing plug is sealingly and slidably connected to the first inner cylinder; The driving rod assembly also includes an elastic telescopic structure adapted to the first sealing plug.

[0009] As a further solution of the present invention: the elastic telescopic structure includes a second sealing plug sealingly and slidably installed in the second inner cylinder, and the second sealing plug is connected to the bottom wall of the second inner cylinder through a first cylindrical spring.

[0010] As a further solution of the present invention: the second sealing plug is annular in structure, and the connecting shaft can pass through the middle thereof; The inner diameter of the second sealing plug is smaller than the outer diameter of the first sealing plug. When the first sealing plug moves to abut against the second sealing plug, the first sealing plug and the second sealing plug can move synchronously.

[0011] As a further solution of the present invention: the pressure applying component includes: A lifting structure, arranged on the frame and connected to the pressure member, wherein a clearance groove is arranged on the lifting structure; The transverse movement structure is slidably connected with the lifting structure, and the transverse movement structure cooperates with the clearance groove and the connecting plate, and can be locked after the pressure member generates a predetermined pressure on the workpiece.

[0012] As a further solution of the present invention: the lifting structure comprises a side plate fixedly mounted on the frame, the side plate is provided with a slide groove along its length direction, a slider is slidably mounted in the slide groove, and the slider is connected to the top wall of the slide groove through a second cylindrical spring; A connecting frame is fixedly installed on one side of the sliding block, and the connecting frame is fixedly connected to the pressure member.

[0013] As a further solution of the present invention: the clearance groove includes a vertical groove and an inclined groove arranged on the side plate.

[0014] As a further solution of the present invention: the transverse movement structure comprises a transverse movement member slidably connected to the other side of the slider, the transverse movement member is provided with a sliding connection portion along its length direction, and the sliding connection portion is slidably connected to a hysteresis groove horizontally provided on the slider; The transverse movement structure further comprises an abutment shaft and an embedded shaft rotatably mounted on the transverse movement member, wherein the embedded shaft can roll in the clearance groove; The connecting plate is provided with an inclined surface and a vertical surface, which are adapted to the abutting shaft.

[0015] A method for stamping a workpiece using the continuous stamping forming equipment based on deformation suppression comprises the following steps: Step 1, placing the workpiece to be stamped on the support; Step 2, controlling the action of the external pump assembly, so that the pump assembly can fill the hydraulic oil into the driving cylinder, so that the driving rod assembly drives the upper stamping die to move toward the lower stamping die; Step 3: When the upper punching die moves to a predetermined position, the driving rod group reduces the movement speed of the upper punching die; Step 4: the upper stamping die drives the connecting plate to abut against the pressure component, so that the pressure component and the support part cooperate to clamp the workpiece to be stamped; Step 5: The upper stamping die cooperates with the lower stamping die to complete the stamping action.

[0016] Compared with the prior art, the present invention has the following beneficial effects: Through the designed drive cylinder and drive rod group, firstly, the drive rod group can obtain a faster movement speed in the first inner cylinder, thereby driving the upper stamping die to move quickly toward the lower stamping die, effectively shortening the movement time of the upper stamping die, significantly improving the working efficiency of the stamping equipment, enabling it to enter the stamping stage faster, and meeting the initial demand for high-efficiency production. Secondly, when the drive rod group moves in the second inner cylinder, it can perform precise stamping at a slower speed. This speed reduction greatly reduces the impact force caused by the excessively fast stamping speed, effectively avoids the workpiece deformation problem caused by this, ensures the stamping quality of the workpiece, reduces the scrap rate caused by the deformation of the workpiece, reduces the production cost, and also helps to extend the service life of the stamping die, improves the reliability and stability of the entire stamping process, and provides a strong guarantee for the production of high-quality workpieces. The workpiece is clamped by the set pressure component. When the workpiece tends to deform under the action of the punching pressure, the stable clamping of the pressure member and the support part can generate multi-directional reverse pulling force on the workpiece, thereby effectively suppressing the deformation of the workpiece during the punching process, significantly reducing the deformation of the workpiece, and improving the punching accuracy and quality of the workpiece.

Detailed implementation manner

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] In addition, an element in the present invention is referred to as being "fixed to" or "disposed on" another element, which can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation.

[0029] Please refer to Figures 1 to 9 , in the embodiment of the present invention, a continuous stamping forming device based on deformation suppression includes: a frame 1, a driving rod group, a lower stamping die 10, a pressing component and a connecting plate 9.

[0030] A driving cylinder body 2 is provided on the frame 1. Specifically, the driving cylinder body 2 is fixedly installed on the frame 1, and a first inner cylinder 201 and a second inner cylinder 202 are formed on the driving cylinder body 2. The first inner cylinder 201 is disposed above the second inner cylinder 202, and the circumferential diameter of the first inner cylinder 201 is smaller than the circumferential diameter of the second inner cylinder 202.

[0031] In practical applications, the driving rod group is placed inside the driving cylinder body 2. When an external pump pressure device injects hydraulic oil into the driving cylinder body 2 at a constant speed, the hydraulic oil will first fill the first inner cylinder 201 in the upper part of the driving cylinder body 2. After it is filled, it will continue to be injected to fill the second inner cylinder 202 in the lower part. Since the injection speed of the hydraulic oil remains constant and the circumferential diameter of the first inner cylinder 201 is smaller than the circumferential diameter of the second inner cylinder 202, this enables the driving rod group to obtain a faster movement speed in the first inner cylinder 201, thereby driving the upper stamping die 7 to move downward rapidly towards the lower stamping die 10, effectively shortening the movement time of the upper stamping die 7, significantly improving the working efficiency of the stamping device, enabling it to enter the stamping stage faster, and meeting the initial requirements of high-efficiency production.

[0032] When the driving rod group enters the second inner cylinder 202 and moves inside it, due to the combined effect of the structure and the injection speed of the hydraulic oil, the movement speed of the driving rod group becomes relatively slow at this time. This enables the upper stamping die 7 to perform precise stamping at a slower speed during the stamping process in cooperation with the lower stamping die 10. This slowdown in speed greatly reduces the impact force generated due to too fast stamping speed, effectively avoids the workpiece deformation problem caused thereby, ensures the stamping quality of the workpiece, reduces the scrap rate caused by workpiece deformation, reduces the production cost, and at the same time helps to extend the service life of the stamping die, improves the reliability and stability of the entire stamping process, and provides a strong guarantee for producing high-quality workpieces.

[0033] Please refer to Figure 2 、 Figure 4 As shown in FIGS. The driving rod group is arranged in the driving cylinder block 2, and one end of the driving rod group is detachably connected with the upper stamping die 7. After the driving rod group drives the upper stamping die 7 to move to a predetermined position at a predetermined speed, the driving rod group can reduce the speed of driving the upper stamping die 7. Wherein, two guiding shafts 8 are arranged on the upper stamping die 7, and the guiding shafts 8 are slidably connected with the frame 1; The driving rod group further includes an elastic telescopic structure adapted to the first sealing plug 3. The elastic telescopic structure includes a second sealing plug 5 that is hermetically slidably installed in the second inner cylinder 202. A first cylindrical spring 6 is connected between the second sealing plug 5 and the bottom wall of the second inner cylinder 202.

[0034] Wherein, the second sealing plug 5 is in a ring structure, and the connecting shaft 4 can penetrate through the middle thereof; The inner diameter of the second sealing plug 5 is smaller than the outer diameter of the first sealing plug 3. When the first sealing plug 3 moves to abut against the second sealing plug 5, the first sealing plug 3 and the second sealing plug 5 can move synchronously.

[0035] In the initial state of this embodiment, the first cylindrical spring 6 provides a supporting force for the second sealing plug 5, prompting the second sealing plug 5 to closely fit with the top wall of the second inner cylinder 202. At the same time, under the action of negative pressure, the first sealing plug 3 also firmly fits with the top wall of the first inner cylinder 201. The whole system is in a stable and well-sealed standby state, laying a foundation for the smooth development of subsequent stamping operations.

[0036] When the stamping operation is started and hydraulic oil is injected into the first inner cylinder 201, a strong driving force will act on the first sealing plug 3. Under the push of the hydraulic oil, the first sealing plug 3 drives the upper stamping die 7 to move towards the lower stamping die 10 at a relatively fast speed through the connecting shaft 4. In this rapid movement process, the downward movement time of the upper stamping die 7 is greatly shortened, effectively improving the initial operation efficiency of the stamping operation, enabling the equipment to quickly enter the stamping stage and meet the requirements of high-efficiency production.

[0037] As the first sealing plug 3 continues to move until it reaches the lower end of the first inner cylinder 201, at this time, the first sealing plug 3 fits with the second sealing plug 5, and the two cleverly combine into a piston structure with a larger area. Under the continuous injection and push of the hydraulic oil, the first sealing plug 3 and the second sealing plug 5 start to move synchronously, driving the upper stamping die 7 to continue moving towards the lower stamping die 10 at a relatively slow and stable speed. This conversion of speed enables the upper stamping die 7 to perform the stamping of workpieces with the lower stamping die 10 at a slow and precise rhythm. This can not only avoid the huge impact force generated by too fast stamping speed, but also effectively prevent the workpiece from deforming due to strong impact, thus significantly improving the stamping quality of the workpiece, reducing the scrap rate, and saving production costs for the enterprise.

[0038] During the entire stamping process, the first cylindrical spring 6 can be gradually compressed when the hydraulic oil pushes the sealing plug to move, accumulating elastic potential energy. When the stamping operation is completed and the external pump pressure device starts to recover the hydraulic oil, at this time, the first cylindrical spring 6 releases the accumulated elastic potential energy, providing an upward supporting force for the first sealing plug 3 and the second sealing plug 5, enabling them to move upward synchronously, and then driving the upper stamping die 7 to quickly and smoothly reset. This reset process is rapid and precise, making full preparations for the next cycle of stamping operation and further improving the overall operation efficiency of the equipment.

[0039] It is worth mentioning that both the first sealing plug 3 and the second sealing plug 5 are made of magnetic materials, and there is a magnetic force of mutual attraction between them, making them fit more closely and stably when they are in contact, effectively avoiding the possible dislocation or loosening phenomenon during the movement process, thus enhancing the reliability of the sealing structure and ensuring the stable operation of the hydraulic system. In addition, sealing rings are provided on the circumferential side parts of the first sealing plug 3 and the second sealing plug 5, which further improves the sealing performance between them and the driving cylinder block 2, effectively preventing the leakage of hydraulic oil and ensuring the efficient and stable operation of the entire stamping system.

[0040] Please refer to Figures 5 to 9 , the lower stamping die 10 is arranged on the frame 1, and multiple groups of supporting parts 11 are arranged on the side of the lower stamping die 10; The pressure-applying assembly is arranged on both sides of the frame 1, and a pressure-applying member 18 adapted to the support portion 11 is connected to the pressure-applying assembly; The pressure-applying assembly comprises a lifting structure and a transverse movement structure.

[0041] The lifting structure is arranged on the frame 1 and connected to the pressure member 18, and a clearance groove 19 is arranged on the lifting structure; The lifting structure includes a side plate 12 fixedly mounted on the frame 1, the side plate 12 is provided with a slide groove 1201 along its length direction, a slider 13 is slidably mounted in the slide groove 1201, and the slider 13 is connected to the top wall of the slide groove 1201 via a second cylindrical spring 20; A connecting frame 17 is fixedly installed on one side of the slide block 13, and the connecting frame 17 is fixedly connected to the pressure member 18. The clearance groove 19 includes a vertical groove 1901 and an inclined groove 1902 provided on the side plate 12; The connecting plate 9 is connected to the upper stamping die 7 , and cooperates with the pressure assembly to be locked after the pressure member 18 descends to a predetermined position. An inclined surface 901 and a vertical surface 902 are provided on the connecting plate 9 , and the two are adapted to the abutment shaft 15 .

[0042] In the initial state, the second cylindrical spring 20 is in a naturally extended state and can pull the slider 13. This pulling force further acts on the pressure piece 18, causing it to have a tendency to move upward, thereby forming a certain height difference with the support portion 11, which facilitates placing the workpiece to be stamped on the support portion 11 and the lower stamping die 10, wherein the height of the support portion 11 is the same as the height of the lower stamping die 10, ensuring that the workpiece is placed stably.

[0043] When the upper stamping die 7 starts and moves toward the lower stamping die 10, the connecting plate 9 interacts with the transverse movement structure. When the transverse movement structure abuts against the inclined surface 901, it is restricted by the vertical groove 1901 and can move downward and drive the pressure member 18 to move downward synchronously. When the transverse movement structure moves along the inclined groove 1902 until it is separated from the inclined surface 901, its height remains constant. At this time, the pressure member 18 acts on the workpiece accurately with a predetermined force, and forms a stable clamping force together with the support part 11 to ensure that the workpiece is firmly clamped during the stamping process.

[0044] This clamping mechanism plays a key role in the stamping process. When the workpiece tends to deform under the action of the stamping pressure, the stable clamping of the pressure member 18 and the support part 11 can generate multi-directional reverse pulling force on the workpiece, thereby effectively suppressing the deformation of the workpiece during the stamping process, significantly reducing the deformation of the workpiece, and improving the stamping accuracy and quality of the workpiece.

[0045] The transverse movement structure is slidably connected with the lifting structure, and the transverse movement structure cooperates with the clearance groove 19 and the connecting plate 9, and can be locked after the pressure member 18 generates a predetermined pressure on the workpiece, and the transverse movement structure includes a transverse movement member 14 slidably connected with the other side of the slider 13, and the transverse movement member 14 is provided with a sliding connection part 1401 along its length direction, and the sliding connection part 1401 is slidably connected with the hysteresis groove 1301 horizontally provided on the slider 13; The transverse movement structure further includes an abutment shaft 15 and an embedded shaft 16 rotatably mounted on the transverse movement member 14 , and the embedded shaft 16 can roll in the clearance groove 19 .

[0046] In the initial state, the embedded shaft 16 is located in the vertical groove 1901, and the transverse moving part 14 is locked in the horizontal direction and cannot move left and right. When the upper stamping die 7 is started and the inclined surface 901 of the connecting plate 9 contacts the abutment shaft 15, the transverse moving part 14 can only move downward, and the pressure member 18 is driven to move toward the workpiece through the slider 13 and the connecting frame 17, ready for stamping.

[0047] When the embedded shaft 16 moves downward to the bottom of the vertical groove 1901, it starts to slide horizontally along the inclined groove 1902. At this time, the transverse member 14 moves horizontally relative to the slider 13, driving the abutment shaft 15 to move out of the inclined surface 901 and fit with the vertical surface 902. The transverse member 14 is then locked, and the height of the pressure member 18 remains constant, cooperating with the support part 11 to firmly clamp the workpiece to prevent it from deforming during the stamping process.

[0048] As an embodiment of the present invention, a method for stamping a workpiece using the continuous stamping forming device based on deformation suppression is also proposed, comprising the following steps: Step 1: placing the workpiece to be stamped on the support portion 11; Step 2: Control the action of the external pump assembly, so that the pump assembly can fill the hydraulic oil into the drive cylinder 2, so that the drive rod assembly drives the upper stamping die 7 to move toward the lower stamping die 10; Step 3, when the upper punching die 7 moves to a predetermined position, the driving rod group reduces the movement speed of the upper punching die 7; Step 4: the upper stamping die 7 drives the connecting plate 9 to abut against the pressure component, so that the pressure member 18 and the support part 11 cooperate to clamp the workpiece to be stamped; Step 5: The upper stamping die 7 cooperates with the lower stamping die 10 to complete the stamping action.
