Description

Technical Field

[0001] The present invention relates to the technical field of hot stamping dies, and more specifically, to a hot stamping hardware die. Background Art

[0002] A hot stamping die is a stamping tool used for hot stamping process forming of a heated part plate, thereby helping technicians to perform stamping of different shapes on the heated part plate, and then evaluating whether the hot stamping die is qualified according to the forming quality of the stamped parts, and mass-producing the evaluated qualified hot stamping dies and putting them on the market for customers to buy and use.

[0003] In the process of stamping parts with the existing hot stamping die, generally, a specified stamping die is first installed at the bottom of the stamping machine, and the cut part plate is sent into the calcining furnace to be burned red, and then the red-hot part plate is placed on the stamping table. At this time, the stamping machine can be started to drive the stamping die to move down for stamping, and then the stamping machine is driven to move up to pull the stamping die apart. At this time, the part can be stamped.

[0004] However, since the stamping die has a fixed shape, the stamping machine with a straight-down punching trajectory can only drive the stamping die to perform stamping on the part plate in a single horizontal form. When the part plate mold needs to be stamped obliquely, the stamping die cannot be adjusted for angle and then stamped. Furthermore, after the stamping die contacts the part plate, vibration will occur, resulting in stamping wear of the part, scratching of the stamping opening of the die, and deformation, causing the problem of poor service life of the stamping die and seriously affecting the normal use of the hot stamping die.

[0011] Furthermore, a clamping groove is penetrated and opened on the left inner wall of the semi-frame-shaped base, and the left end of the first bevel telescopic block penetrates through and is clamped inside the clamping groove.

[0012] Furthermore, contact shock-absorbing components are symmetrically arranged on the top of the concave hot stamping die. There are two contact shock-absorbing components, and each contact shock-absorbing component includes a second bevel telescopic block. The outer surface of the second bevel telescopic block penetrates through and is slidably connected to the concave hot stamping die, and a second spring is fixedly connected between the front side of the second bevel telescopic block and the inner side of the top of the concave hot stamping die.

[0013] Furthermore, a scraping component is arranged between the inner walls of the concave hot stamping die.

[0017] Advantages of the present invention compared with the prior art:

[0018] (1) By setting the corner swing assembly in this solution, under the continuous forward extending force of the cylinder output end, the concave hot stamping die can be indirectly swung counterclockwise. After the die opening of the concave hot stamping die is swung counterclockwise to the same plane angle as the template part to be stamped, under the drive of the stamping machine, the part plate die with a non-parallel surface and a certain angle can be stamped. Therefore, the concave hot stamping die can perform stamping operations on the part plate at different angles, avoiding the situation that when the concave hot stamping die is used, it can only perform a single fixed-form stamping on the part plate, resulting in serious stamping wear of the concave hot stamping die, rough part surface, and deformation after long-term use of the concave hot stamping die, causing problems such as die sticking at the die opening of the concave hot stamping die, deformation of the die opening, and damage to the part, improving the efficiency of stamping parts by the concave hot stamping die, enhancing the effect of stamping parts at multiple angles without obstacles by the concave hot stamping die, and ensuring the normal use of high-efficiency stamping of parts.

[0019] (2) By setting the clamping assembly in this solution, under the continuous forward rotating force of the hollow frame, the bevel telescopic block one can indirectly squeeze the spring back and forth to perform a clamping operation on the card slot, providing a stable support environment for the shape of the hollow frame and the concave hot stamping die after cornering. Avoiding problems such as stamping deformation of the part and large-area abrasion of the part due to the vibration force interference generated by the concave hot stamping die punching the part during the stamping process of the concave hot stamping die after cornering, resulting in poor use effect of the part after stamping, improving the accuracy of the concave hot stamping die for stably stamping parts, enhancing the force of the concave hot stamping die for stamping parts without damage, and ensuring the normal use of the high-quality stamping process of the concave hot stamping die.

[0020] (3) By setting the contact shock absorption assembly in this solution, under the action of the downward punching force of the concave hot stamping die, the bevel telescopic block two can indirectly perform contact shock absorption operation on the stamped part, avoiding the phenomenon of part pulling and rebounding when the concave hot stamping die punches and pulls up to the separation position from the part surface due to the influence of the shape of some concave parts after stamping the part plate, resulting in problems such as secondary wear of the stamped part and serious part scratches, causing the problem of low service life of the part after stamping, improving the effectiveness of the part after stamping, enhancing the effect of the concave hot stamping die for stamping parts smoothly without interference, and ensuring the normal progress of part stamping and forming.

[0021] (4) By setting the scraping component, under the continuous moving force of the square slider, the concave scraper can be indirectly moved downward, pressing the telescopic plate to contract downward. At this time, the cutting edge at the bottom of the concave scraper can closely adhere to the inner groove wall of the concave hot stamping die for downward scraping operation, thereby reducing the residual part debris adhering to the concave inner wall of the concave hot stamping die after stamping parts, which may cause wear and scratches on the part plate when the concave hot stamping die stamps the part plate for the second time, resulting in the problem that the concave hot stamping die cannot be used, improving the flexibility of stable part stamping, enhancing the effect of interference-free and high-efficiency stamping of the concave hot stamping die, prolonging the service life of the concave hot stamping die, and ensuring the normal use of the concave hot stamping die without foreign objects during stamping.

[0040] 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 the 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.

[0041] Please refer to Figures 1 to 12 , a hot stamping hardware die, including a semi-frame base 1, and a corner swing component 2 is arranged between the inner walls of the semi-frame base 1;

[0042] The corner swing assembly 2 includes a first fixed rod 22 which is fixedly connected to the top wall of the semi-frame base 1. The bottom of the first fixed rod 22 penetrates and is rotatably connected to a cylinder 21. The output end of the cylinder 21 is rotatably connected to a second fixed rod 23. The bottom of the second fixed rod 23 is fixedly connected to a concave hot stamping die 28. The top of the concave hot stamping die 28 is fixedly connected to a hollow frame 27. The bottom of the hollow frame 27 penetrates and is fixedly connected to the second fixed rod 23. The outer surface of the cylinder 21 slides in the inner cavity of the hollow frame 27. An arc-shaped groove one 24 and an arc-shaped groove two 210 are formed on the left side of the hollow frame 27. The arc-shaped groove one 24 and the arc-shaped groove two 210 are symmetrically distributed with respect to the hollow frame 27. A first slider 25 is slidably connected inside the arc-shaped groove one 24. A second slider 29 is slidably connected inside the arc-shaped groove two 210. Both sides of the hollow frame 27 are rotatably connected to a rotating shaft 26. The left side of the rotating shaft 26 is fixedly connected to the semi-frame base 1.

[0043] As Figure 3 Shown from the perspective, there are two arc-shaped grooves one 24, and the two arc-shaped grooves one 24 are symmetrically distributed on both sides of the hollow frame 27. There are two arc-shaped grooves two 210, and the two arc-shaped grooves two 210 are symmetrically distributed on both sides of the hollow frame 27. There are two first sliders 25, and the two first sliders 25 are symmetrically distributed inside the arc-shaped groove one 24. There are two second sliders 29, and the two second sliders 29 are symmetrically distributed inside the arc-shaped groove two 210. One side of the first slider 25 and one side of the second slider 29 penetrate and are fixedly connected to the semi-frame base 1.

[0044] Although the arc-shaped groove one 24 and the arc-shaped groove two 210 are both distributed on both sides of the hollow frame 27, the radian of their moving trajectories is the same as the swing amplitude range of the hollow frame 27. And the axis line at the bottom of the cylinder 21 is flush with the inner ring center line of the arc-shaped groove one 24. The rotating shaft 26 is arranged between the bottom of the semi-frame base 1 and the bottom of the hollow frame 27. The purpose is to enable the moving trajectories of the arc-shaped groove one 24 and the arc-shaped groove two 210 to rotate around the rotating shaft 26 while the hollow frame 27 swings at an angle. Therefore, the moving trajectories of the two pairs of grooves can be consistent with the rotating trajectory of the hollow frame 27, and further achieve the normal use of the interference-free corner operation of the hollow frame 27 and the concave hot stamping die 28.

[0045] In the prior art, since the concave hot stamping die 28 has a fixed shape, a stamping machine with a linear downward stamping trajectory can only drive the concave hot stamping die 28 to stamp the part plate in a single horizontal form. When the part plate mold needs to be stamped obliquely, the concave hot stamping die 28 cannot be adjusted in angle for stamping. Therefore, after the concave hot stamping die 28 contacts the part plate, vibration will occur, resulting in stamping wear of the parts, scratching of the stamping opening of the concave hot stamping die 28, and poor service life of the concave hot stamping die 28. In this application, by setting the corner swing assembly 2, when in use, first ventilate to drive the output shaft of the cylinder 21 to extend forward, pushing the fixed rod two 23 connected by rotation to rotate clockwise, and making the fixed rod two 23 drive the top of the concave hot stamping die 28 to rotate clockwise. Since the concave hot stamping die 28 is fixedly connected to the hollow frame 27, the concave hot stamping die 28 drives the hollow frame 27 to rotate clockwise. And the hollow frame 27 is rotationally connected to the rotating shaft 26. The rotation trajectories of the arc-shaped groove one 24 and the arc-shaped groove two 210 are the same as that of the hollow frame 27. Therefore, under the action of the clockwise rotation force of the hollow frame 27, the two sides of the hollow frame 27 rotate around the axis line of the rotating shaft 26 as the center. At the same time, the hollow frame 27 drives the opened arc-shaped groove one 24 to slide clockwise closely along the outer surface of the slider one 25, and drives the opened arc-shaped groove two 210 to slide clockwise closely along the outer surface of the slider two 29. Thus, while the top of the concave hot stamping die 28 swings clockwise, the bottom of the hollow frame 27 can drive the outer surface of the concave hot stamping die 28 to rotate counterclockwise. Therefore, when it is necessary to stamp the part plate obliquely, after the right end groove wall of the arc-shaped groove one 24 swings clockwise to contact the outer wall of the slider one 25, and at the same time the right end groove wall of the arc-shaped groove two 210 swings clockwise to contact the outer wall of the slider two 29, the concave hot stamping die 28 can complete the adjustment of the inclination angle at this time. At this time, the cylinder 21 also stops running and remains stationary. Further, driven by the stamping machine, the part plate mold with a non-parallel surface and a certain angle can be stamped. Therefore, the concave hot stamping die 28 can perform stamping operations on the part plate at different angles, avoiding the situation that when the concave hot stamping die 28 is in use, because the stamping method of the concave hot stamping die 28 on the part plate is linear stamping, and the concave hot stamping die 28 can only perform a single horizontal plane stamping on the part plate. When it is necessary to stamp the part plate at a non-parallel angle, the concave hot stamping die 28 cannot rotate the angle to stamp the part plate, resulting in wear of the die opening of the concave hot stamping die 28, rough surface and deformation of the parts after stamping, causing problems such as die sticking at the die opening of the concave hot stamping die 28 and inability to use. It improves the efficiency of the concave hot stamping die 28 in stamping the part plate, enhances the effect of multi-angle and high-quality stamping of the concave hot stamping die 28, and ensures the normal use of the stamping process of the concave hot stamping die 28.

[0046] It should be noted that while the concave hot stamping die 28 swings counterclockwise, the arc-shaped grooves 24 on both sides of the hollow frame 27 can slide forward along the outer surface of the first slider 25, and the arc-shaped groove 210 can slide forward along the outer surface of the second slider 29. Therefore, after the concave hot stamping die 28 swings by a certain angle, the arc-shaped grooves 24 and 210 can provide a support environment for the swung concave hot stamping die 28, reduce the instability after the concave hot stamping die 28 turns, and ensure the effective stamping of non-parallel angle parts by the concave hot stamping die 28. When the right end of the arc-shaped groove 24 contacts the outer surface of the first slider 25 and the right end of the arc-shaped groove 210 also contacts the outer surface of the second slider 29, the concave hot stamping die 28 can move to the non-parallel plane angle. At the same time, the maximum range of the pre-stamped part angle is also within the non-parallel plane coverage range of the concave hot stamping die 28, so as to ensure that there will be no interference or inability to stamp when the concave hot stamping die 28 stamps parts.

[0047] In this solution, by setting the corner swing assembly 2, under the continuous forward extending force of the output end of the cylinder 21, the concave hot stamping die 28 can be indirectly swung counterclockwise. After the die orifice of the concave hot stamping die 28 swings counterclockwise to the same plane angle as the template part to be stamped, under the drive of the stamping machine, the part plate mold with a certain angle on the non-parallel plane can be stamped. Therefore, the concave hot stamping die 28 can perform stamping operations on the part plate at different angles, avoiding the situation that when the concave hot stamping die 28 is used, it can only perform a single fixed-form stamping on the part plate, resulting in serious stamping wear of the concave hot stamping die 28, rough part surface, and deformation after long-term use, causing problems such as die sticking at the die orifice of the concave hot stamping die 28, deformation of the die orifice, and damage to parts, improving the efficiency of stamping parts by the concave hot stamping die 28, enhancing the effect of multi-angle obstacle-free stamping of parts by the concave hot stamping die 28, and ensuring the normal use of high-efficiency stamping of parts.

[0048] As Figures 4 to 7 shown, clamping components 3 are symmetrically arranged on the inner wall of the semi-frame-shaped base 1, and there are two clamping components 3;

[0049] The clamping component 3 includes a first hollow box 31, and the right side of the first hollow box 31 penetrates and is fixedly connected to the hollow frame 27.

[0050] A first bevel telescopic block 32 penetrates and is slidably connected to the left side of the first hollow box 31. A first spring 33 is fixedly connected to the right side of the first bevel telescopic block 32, and the right end of the first spring 33 is fixedly connected to the first hollow box 31.

[0051] A clamping groove 34 is formed through the left inner wall of the semi-frame base 1, and the left end of the bevel telescopic block 32 penetrates and is clamped inside the clamping groove 34.

[0052] By setting the clamping component 3, during use, while the top of the hollow frame 27 rotates forward, the first hollow box 31 can be driven to rotate forward, and the first hollow box 31 drives the bevel telescopic block 32 to rotate forward. When the front inclined surface of the bevel telescopic block 32 moves forward to be flush with the front side of the clamping groove 34, under the continuous rotational force of the hollow frame 27, the inclined surface of the bevel telescopic block 32 can move to the right, and the right side of the bevel telescopic block 32 squeezes the first spring 33 to contract into the first hollow box 31. The right side edge of the clamping groove 34 and the inner wall of the semi-frame base 1 are on the same horizontal plane. When the left inclined surface of the bevel telescopic block 32 moves to the right to be flush with the inner wall of the semi-frame base 1, the bevel telescopic block 32 can be separated from the clamping groove 34. At this time, the hollow frame 27 is in an unfixed state. Then, under the continuous forward rotational force of the hollow frame 27, the bevel telescopic block 32 drives the compressed first spring 33 to rotate forward. When the left end of the bevel telescopic block 32 rotates forward to be flush with the rear side of another clamping groove 34, under the continuous forward swinging force of the first hollow box 31, the first spring 33 that forms a counter-thrust by extrusion can push the bevel telescopic block 32 to extend to the left. Therefore, the left inclined surface of the bevel telescopic block 32 can gradually come into contact with the inside of another clamping groove 34. When the left end of the bevel telescopic block 32 extends to the left to contact the left inner wall of the clamping groove 34, the bevel telescopic block 32 can be completely clamped with the clamping groove 34. At this time, the hollow frame 27 after rotating a certain angle can be in a fixed state, ensuring that the hollow frame 27 can provide stable support for the inclined shape of the concave hot stamping die 28, avoiding the instability during the downward punching process of the concave hot stamping die 28 with an inclined angle when stamping a non-parallel surface part plate. Therefore, when the die opening of the concave hot stamping die 28 contacts the part, vibration force will be generated, resulting in the angle direction change of the concave hot stamping die 28 during part stamping, leading to a disordered shape of the stamped part and serious large-area abrasion of the part, and causing problems with the poor use effect of the part stamped by the concave hot stamping die 28. It improves the accuracy of the concave hot stamping die 28 for stamping parts stably, enhances the clamping and supporting force of the bevel telescopic block 32 for angle fixation, and ensures the normal use of the stamping process of the concave hot stamping die 28.

[0053] In this solution, by setting the clamping component 3, under the continuous forward rotational force of the hollow frame 27, the bevel telescopic block one 32 can indirectly squeeze the spring one 33 back and forth to perform the clamping operation on the clamping groove 34, providing a stable support environment for the shape of the hollow frame 27 and the concave hot stamping die 28 after rotation. This can prevent problems such as the concave hot stamping die 28 causing the stamped parts to be deformed due to the vibration force generated during the downward punching of the parts, and large-area abrasion of the parts, which may lead to poor use effects after stamping. It improves the accuracy of the concave hot stamping die 28 in stamping parts stably, enhances the force of the concave hot stamping die 28 in stamping parts without damage, and ensures the normal use of the high-quality stamping process of the concave hot stamping die 28.

[0054] As Figures 8 to 10 shown, contact damping components 4 are symmetrically arranged at the bottom of the concave hot stamping die 28;

[0055] There are two contact damping components 4. The contact damping component 4 includes a bevel telescopic block two 41. The outer surface of the bevel telescopic block two 41 penetrates and is slidably connected to the concave hot stamping die 28. A spring two 42 is fixedly connected between the front side of the bevel telescopic block two 41 and the inner side of the bottom of the concave hot stamping die 28.

[0056] By setting the contact damping component 4, during operation, when the stamping machine drives the semi-frame base 1 to move downward, the semi-frame base 1 indirectly drives the hollow frame 27 and the concave hot stamping die 28 to move downward. Then, the concave hot stamping die 28 drives the bevel telescopic block two 41 and the spring two 42 to move downward. When the die orifice of the concave hot stamping die 28 moves downward to contact the part plate, the bevel telescopic block two 41 can contact the part plate. Under the continuous downward force of the concave hot stamping die 28, the inclined surface at the top of the bevel telescopic block two 41 can be gradually squeezed into the concave hot stamping die 28 by the part plate. At the same time, the bevel telescopic block two 41 can squeeze the spring two 42 to move forward. After the rear side of the bevel telescopic block two 41 contracts forward to be parallel to the inner groove wall of the concave hot stamping die 28, the part plate has been stamped into shape. At this time, the spring two 42 squeezed and curled by the bevel telescopic block two 41 can gradually form a reaction force, enabling the spring two 42 to push the bevel telescopic block two 41 to extend backward and closely adhere to the surface of the stamped part. At the same time, the reaction force generated by the spring two 42 can cancel out the vibration force generated after the concave hot stamping die 28 punches the part, reducing the residual vibration force carried by the concave hot stamping die 28 after punching and pulling out, avoiding the possibility of the concave hot stamping die 28 causing pulling rebound and wear to the concave part after stamping, improving the effectiveness of the concave hot stamping die 28 in stamping parts without damage, enhancing the damping stamping effect of the bevel telescopic block two 41 at multiple angles, and ensuring the normal and safe use of parts during stamping.

[0057] By setting up the contact shock-absorbing component 4, under the action of the downward impact force of the concave hot stamping die 28, the bevel telescopic block two 41 can indirectly perform contact shock-absorbing operations on the stamped parts, avoiding the problem that after the concave hot stamping die 28 stamps the part plate, due to the influence of the shape of some concave parts, when the concave hot stamping die 28 stamps and pulls up to the separation position from the part surface, the part pulling-back and rebounding phenomenon occurs, resulting in problems such as secondary wear of the already stamped parts and serious part scratches, and the problem of low service life of the parts after stamping. This improves the effectiveness of the parts after stamping, enhances the effect of the concave hot stamping die 28 stamping parts smoothly without interference, and ensures the normal progress of part stamping and forming.

[0058] As Figure 11 and Figure 12 shown, a scraping component 5 is arranged between the inner walls of the concave hot stamping die 28;

[0059] The scraping component 5 includes a driving motor 51, the driving motor 51 is fixedly connected to the inner wall of the concave hot stamping die 28, the output end of the driving motor 51 is fixedly connected with a bidirectional threaded groove rod 52, the outer surface of the bidirectional threaded groove rod 52 is slidably connected with a square slider 53, the right side of the square slider 53 penetrates and is slidably connected to the inner wall of the concave hot stamping die 28, the right side of the square slider 53 is fixedly connected with a concave scraper 54, the bottom of the square slider 53 is fixedly connected with a telescopic plate 511, and the bottom of the telescopic plate 511 penetrates and is fixedly connected to the concave hot stamping die 28.

[0060] The top of the concave scraper 54 contacts a column rod 510, and the outer surface of the column rod 510 penetrates and is slidably connected to the concave hot stamping die 28.

[0061] The top of the column rod 510 is fixedly connected with a pressing disc 58, the bottom of the pressing disc 58 is fixedly connected with a spring three 59, and the bottom of the spring three 59 is fixedly connected to the inner wall of the concave hot stamping die 28.

[0062] The top of the pressing disc 58 penetrates and is rotatably connected with a swing rod 56, the outer surface of the swing rod 56 penetrates and is rotatably connected with a fixed rod three 57, the bottom of the fixed rod three 57 is fixedly connected to the concave hot stamping die 28, the left end of the swing rod 56 penetrates and is rotatably connected with a start button 55, and the bottom of the start button 55 penetrates and is slidably clamped to the top of the driving motor 51.

[0063] By setting the scraping component 5, during operation, when the top surface of the part gradually comes into contact with the inner bottom of the concave hot stamping die 28, under the continuous downward force of the concave hot stamping die 28, the top surface of the part can squeeze the concave scraper 54 to move upward. At this time, the concave scraper 54 can push the column rod 510 and the square slider 53 upward. Then, the column rod 510 drives the spring three 59 and the extrusion disc 58 to move upward. Therefore, the extrusion disc 58 can push the right end of the swing rod 56 upward. Further, the outer surface of the swing rod 56 rotates around the axis line of the fixed rod three 57. Thus, the right end of the swing rod 56 can rotate upward, causing the left end of the swing rod 56 to rotate downward. Further, the swing rod 56 presses the start button 55 to move downward. When the start button 55 moves downward to be flush with the top surface of the drive motor 51, the drive motor 51 can be energized to drive the output shaft to rotate, driving the fixedly connected bidirectional threaded groove rod 52 to rotate. Then, the rotation of the bidirectional threaded groove rod 52 drives the square slider 53 to move downward. Next, the square slider 53 drives the concave scraper 54 to move downward and presses the telescopic plate 511 to contract downward. At this time, the cutting edge end at the top of the concave scraper 54 can closely adhere to the inner groove wall of the concave hot stamping die 28 for downward scraping operation. Thus, after the concave hot stamping die 28 stamps the part, the residual part debris adhering to the inner wall of the notch of the concave hot stamping die 28 can be reduced. When the concave hot stamping die 28 stamps the part plate for the second time, the part plate will be worn and scratched, resulting in the problem that the concave hot stamping die 28 cannot be used. It improves the flexibility of stable part stamping, enhances the interference-free and high-efficiency stamping effect of the concave hot stamping die 28, prolongs the service life of the concave hot stamping die 28, and ensures the normal use of the concave hot stamping die 28 without foreign objects during stamping.

[0064] It should be noted that after the concave hot stamping die 28 moves downward to contact the fully stamped part plane, at this time, the stamping machine drives the semi-frame base 1, the hollow frame 27, and the concave hot stamping die 28 to move upward. And at this time, the concave scraper 54 can complete the synchronous start and downward movement operation. Therefore, during the upward movement of the concave hot stamping die 28, the downward scraping with the concave scraper 54 is carried out simultaneously and without interference. After the cutting edge end of the concave scraper 54 moves downward to be flush with the bottom surface of the die orifice of the concave hot stamping die 28, the concave hot stamping die 28 is completely separated from the top surface of the stamped part, thus ensuring the normal state of the part remaining stable after safe stamping.

[0065] Usage method: When the present invention is in use, first install the semi-frame base 1 on the top of the stamping machine, then energize to drive the output end of the cylinder 21 in the corner swing assembly 2 to extend forward, so that the corner swing assembly 2 drives the concave hot stamping die 28 to swing counterclockwise for corner operation. Therefore, the clamping assembly 3 can perform clamping and supporting operations on the concave hot stamping die 28 after cornering. Then, after the stamping machine indirectly drives the concave hot stamping die 28 to stamp the casting part plate, the contact shock absorption assembly 4 can perform contact shock absorption operations on the concave hot stamping die 28 and the part during the stamping and pulling-out process, so that the scraping assembly 5 can scrape the debris on the inner groove wall after the concave hot stamping die 28 is stamped. After the part stamping is completed, the stamping angle of the concave hot stamping die 28 can be adjusted continuously according to the above steps until all the part plates are stamped. Then, stop the movement of the output end of the cylinder 21. After the stamping machine is pulled up to separate from the top surface of the part, the device stops running, take out the stamped part, and the stamping is over.

[0066] The above is only the preferred specific implementation manner of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
