Description

Technical Field

[0001] This application relates to the field of stamping equipment technology, and in particular to a four-linkage stamping device. Background Technology

[0002] After tubular parts are produced by injection molding, due to factors such as mold closing clearance and gate design, excess flash, gate material and other redundant parts often remain on the surface of the formed tubular parts. The redundant parts need to be stamped off. The standard for manual removal is not uniform and it is easy to produce defective products. Therefore, a stamping device is needed to stamp off the redundant parts of tubular parts.

[0003] A related four-linkage stamping device includes a fixed base, a placing mold, and a pressing component. The fixed base provides space for the placing mold and the pressing component. The operator places the tubular part on the placing mold, and the pressing component stamps the redundant part of the tubular part. However, in the existing four-linkage stamping device, the inner wall of the tubular part is not supported during stamping, so the stamping cut surface of the tubular part is prone to unevenness, and the tubular part produced by injection molding is also prone to deformation. Utility Model Content

[0004] To reduce the problems of deformation and uneven stamping surfaces of tubular parts during stamping, this application provides a four-linkage stamping device.

[0005] This application provides a four-linkage stamping device, which adopts the following technical solution: A four-linkage stamping device, comprising: A fixed base is fixedly installed on the ground. The fixed base has an installation cavity, and a rotating frame is vertically installed inside the installation cavity. The placement mold is vertically fixed on the fixed base. The placement mold has a vertical placement cavity, which corresponds to the installation cavity. The placement mold has a stamping groove on its periphery. A support assembly is rotatably mounted on a rotating frame, with its upper end corresponding to the placement cavity. The stamping cylinder is horizontally set on a fixed base. Four sets of stamping cylinders are arranged at intervals around the central axis of the mold. A stamping block is fixedly set on the telescopic end of the stamping cylinder, and the stamping block is set in correspondence with the stamping groove. The pressing component has one end fixedly mounted on the fixed base, and the other end of the pressing component is correspondingly mounted on the upper end of the placement cavity; The top material assembly is vertically fixed on the rotating frame, and the top material assembly is set in accordance with the placement cavity.

[0006] By adopting the above technical solution, the fixed base provides installation space for the mold, stamping cylinder, and pressing assembly; the mounting cavity provides installation space for the support assembly; the rotating frame allows the support assembly to rotate within the mounting cavity; the mold placement provides space for the tubular part to be stamped; the stamping cylinder drives the stamping block into the stamping groove and stamps the tubular part; and the support assembly provides support force to the inner wall of the tubular part during rotation, ensuring structural stability during stamping and reducing the risk of deformation due to uneven stress. Furthermore, the combined use of the stamping groove and support assembly results in a smoother cut end face of the tubular part, improving the accuracy and stability of the stamping process. The pressing assembly applies uniform pressure to the upper surface of the tubular part during the stamping process, improving the stability of the tubular part during stamping. After stamping is completed, the pressing assembly can simultaneously remove the waste material generated during the resetting process. The ejector assembly can eject the stamped tubular part from the placement cavity, reducing the difficulty for workers to remove the tubular part from the placement mold, facilitating the subsequent stamping of the next batch of products, and improving the production efficiency and operational safety of the stamping equipment. By using the placement mold and support assembly in combination, the position of the tubular part, excluding the redundant part, is supported during the stamping process, improving the flatness of the stamped cross-section of the tubular part, reducing the risk of deformation of the stamped tubular part, and increasing the product yield of the tubular part.

[0007] Optionally, a horizontally arranged sliding groove is provided on the fixed base, the sliding groove corresponding to the mounting cavity, and multiple sets of sliding grooves are arranged at intervals around the central axis of the placement cavity. The support assembly includes: A rotating plate is rotatably mounted on a rotating frame. A rack is provided on the outer periphery of the rotating plate. A limit groove is provided on the rotating plate, and multiple sets of limit grooves are arranged at intervals around the central axis of the rotating plate. The motor is vertically fixed inside the mounting cavity. The drive gear is fixedly mounted on the output end of the motor and meshes with the rack. The slider is embedded in the groove, and a limit rod is vertically installed on the slider, with the lower end of the limit rod embedded in the limit groove. The support plate has one end fixedly mounted on the side of the slider near the central axis of the rotating plate, and the other end of the support plate extends into the placement cavity.

[0008] By adopting the above technical solution, the rotation of the motor can drive the drive gear to rotate synchronously. Because the drive gear meshes with the rack, the rotation of the drive gear can drive the rotating plate to rotate around the central axis of the rotating frame. When the rotating plate rotates, the limiting rod is guided by the limiting groove to move away from the central axis of the rotating plate. The movement of the limiting rod drives the slider to slide synchronously in the groove. The movement of the slider drives the support plate to move synchronously, thereby causing the support plate to move closer to the inner side wall of the placement cavity, and finally abut against the inner side wall of the tubular part, providing uniform internal support force for the tubular part. This ensures that the tubular part maintains structural stability during the stamping process and reduces the risk of deformation of the tubular part due to uneven force.

[0009] Optionally, the pressure-down component includes: The mounting bracket is vertically and fixedly mounted on the base. The downward pressure cylinder is vertically fixed on the mounting bracket, and the telescopic end of the downward pressure cylinder is set to correspond to the placement cavity. The connecting rod is vertically fixed on the telescopic end of the downward pressing cylinder; The scrap plate is horizontally fixed at the end of the connecting rod away from the downward pressing cylinder; The lower pressure plate is sleeved on the connecting rod and is slidably connected to the connecting rod. A spring is wound around a connecting rod. One end of the spring is fixedly connected to the lower pressure plate, and the other end of the spring is fixedly connected to the scrap plate.

[0010] By adopting the above technical solution, the mounting bracket provides installation space for the pressing cylinder. The extension and retraction of the pressing cylinder can drive the connecting rod to move synchronously. The movement of the connecting rod drives the scrap plate to move synchronously. When the pressing cylinder extends, the connecting rod drives the scrap plate and the pressing plate to move towards the placement cavity. The scrap plate first enters the tubular part. When the pressing plate contacts the top of the tubular part, the pressing cylinder continues to extend and drives the connecting rod to continue moving into the placement cavity. At this time, the distance between the pressing plate and the scrap plate increases, and the spring is stretched by tension. Under the action of the spring force, the pressing plate continuously applies pressure to the top of the tubular part, so that the lower end of the tubular part is tightly fitted with the support assembly, thereby ensuring that the tubular part remains stable during the stamping process. The scrap generated during stamping falls onto the scrap plate. After the stamping is completed, the pressing cylinder retracts and drives the scrap plate to reset and leave the placement cavity, thereby achieving the purpose of separating the scrap from the tubular part. This facilitates the subsequent cleaning of the scrap and the removal of the tubular part, reducing the accumulation of scrap inside the stamping device and its impact on subsequent operations.

[0011] Optional, the top material assembly includes: The electric telescopic rod is vertically fixed on the rotating frame, and the telescopic end of the electric telescopic rod is set to correspond to the placement cavity. The top material frame is horizontally fixed on the telescopic end of the electric telescopic rod.

[0012] By adopting the above technical solution, the extension of the electric telescopic rod can drive the top material rack to move upward along the central axis of the placement cavity. The upward movement of the top material rack pushes the tubular parts that have been stamped to detach from the support assembly and leave the placement cavity, making it easier for workers to pick up the parts.

[0013] Optionally, the upper part of the mold is provided with rounded corners.

[0014] By adopting the above technical solution, the rounded corners facilitate the smooth guidance of tubular parts when they are placed into the placement cavity, reducing the probability of assembly jamming or damage to the surface of the parts caused by right angles at the edges.

[0015] Optionally, the curvature of the side of the support plate extending into the placement cavity is the same as the curvature of the inner wall of the placement cavity.

[0016] By adopting the above technical solution, the support plate and the placement cavity have the same curvature, which makes the outer wall of the tubular part and the inner wall of the placement cavity fit tightly together, and the inner wall of the tubular part and the support plate fit tightly together. This improves the support stability of the support plate for the tubular part, effectively reduces the probability of deformation or displacement of the tubular part during the stamping process, and improves the stamping accuracy of the tubular part.

[0017] Optionally, the height of the upper part of the support plate is flush with the height of the bottom of the stamping groove.

[0018] By adopting the above technical solution, the support plate can support the non-stamping processing area of ​​the tubular part, effectively reducing the probability of deformation or displacement of the tubular part during the stamping process and improving the stamping processing accuracy of the tubular part.

[0019] Optionally, the diameter of the lower pressure plate is the same as the diameter of the placement cavity, and the diameter of the scrap plate is the same as the inner diameter of the stamped product.

[0020] By adopting the above technical solution, the lower pressure plate can attach to the top of the tubular part and press the tubular part onto the support assembly. The diameter of the scrap plate is the same as the inner diameter of the tubular part, which enables the scrap plate to bear the scrap generated by the stamping process and drive the scrap away from the placement cavity, reducing the impact of scrap residue on the next stamping operation.

[0021] In summary, this utility model embodiment provides a four-linkage stamping device, which includes at least one of the following beneficial technical effects: 1. The fixed base provides installation space for the mold, stamping cylinder, and pressing assembly. The mounting cavity provides installation space for the support assembly. The rotating frame allows the support assembly to rotate within the mounting cavity. The mold placement provides space for the tubular part to be stamped. The stamping cylinder drives the stamping block into the stamping groove and stamps the tubular part. During rotation, the support assembly provides support force to the inner wall of the tubular part, ensuring structural stability during stamping and reducing the risk of deformation due to uneven stress. Simultaneously, the stamping groove and support assembly work together to make the cut end face of the tubular part smoother, improving the accuracy and stability of the stamping process. The pressing assembly... Applying uniform pressure to the upper surface of the tubular part during the stamping process improves its stability. After stamping, the pressing assembly can simultaneously remove the waste material generated during the resetting process. The ejector assembly can push the stamped tubular part out of the placement cavity, reducing the difficulty for workers to remove the tubular part from the placement mold and facilitating the stamping of the next batch of products. This improves the production efficiency and operational safety of the stamping equipment. By using the placement mold and support assembly in conjunction, the position of the tubular part, excluding the redundant part, is supported during the stamping process, improving the flatness of the stamped cut surface of the tubular part, reducing the risk of deformation after stamping, and increasing the product yield of the tubular part.

[0022] 2. The extension of the electric telescopic rod can drive the top material rack to move upward along the central axis of the placement cavity. The upward movement of the top material rack pushes the completed stamping tubular parts away from the support assembly and out of the placement cavity, making it easier for workers to pick up the parts.

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This application discloses a four-linkage stamping device, including: a fixed base 41, a placement mold 42, a support assembly 1, a stamping cylinder 43, a pressing assembly 2, and an ejector assembly 3. The fixed base 41 is fixedly mounted on the ground and has a mounting cavity 51. A rotating frame 44 is vertically mounted inside the mounting cavity 51. The placement mold 42 is vertically fixedly mounted on the fixed base 41 and has a placement cavity 53 vertically mounted on it. The placement cavity 53 corresponds to the mounting cavity 51. A stamping groove 54 is provided around the periphery of the placement mold 42. The support assembly 1 rotates. The upper end of the support component 1 is positioned on the rotating frame 44 and corresponds to the placement cavity 53. The stamping cylinder 43 is horizontally positioned on the fixed base 41. Four sets of stamping cylinders 43 are spaced around the central axis of the placement mold 42. A stamping block 47 is fixedly positioned on the telescopic end of the stamping cylinder 43. The stamping block 47 corresponds to the stamping groove 54. One end of the pressing component 2 is fixedly positioned on the fixed base 41, and the other end of the pressing component 2 corresponds to the upper end of the placement cavity 53. The ejector component 3 is vertically fixedly positioned on the rotating frame 44 and corresponds to the placement cavity 53.

[0027] In this embodiment, the fixed base 41 is rectangular, the mounting cavity 51 is an equiaxial cylinder with different diameters, and the upper end of the mounting cavity 51 is an open end. The rotating frame 44 is a hollow cylinder, and a rotating groove 56 is provided at the upper end of the rotating frame 44. The rotating groove 56 is annular, and one end of the support component 1 is rotatably mounted on the rotating groove 56. The placement mold 42 is rectangular, and a placement cavity 53 is provided at the center of the placement mold 42. The placement cavity 53 is cylindrical and coaxial with the mounting cavity 51. The diameter of the placement cavity 53 is the same as the diameter of the open end of the mounting cavity 51, and the diameter of the placement cavity 53 is... Similar to the outer diameter of the tubular part, the upper end of the placement mold 42 is rounded, allowing the tubular part to be smoothly and accurately embedded into the placement cavity 53 and correspondingly placed with the support component 1 in the mounting cavity 51. The pressing component 2 applies pressure to the tubular part placed in the placement cavity 53, ensuring that the lower end of the tubular part fits tightly with the support component 1, thereby ensuring the stability of the tubular part during stamping. The support component 1 applies a horizontal supporting force to the tubular part, maintaining structural stability during stamping and reducing the risk of deformation due to uneven stress. The stamping groove 54 is rectangular. The stamping groove 54 and the placement cavity 53 are connected. The telescopic end of the stamping cylinder 43 is correspondingly set to the placement cavity 53. The stamping block 47 is rectangular. When the stamping cylinder 43 extends, it can drive the stamping block 47 to extend into the stamping groove 54 and stamp and remove the redundant part of the tubular part. Four sets of stamping cylinders 43 are symmetrically arranged around the central axis of the placement cavity 53. When the stamping cylinders 43 are stamping a set of tubular parts, the four sets of stamping cylinders 43 are started in two batches. The two sets of stamping cylinders 43 in opposite positions extend and retract first to complete the stamping work, so that the stamping cylinders 43 will not interfere with each other when they extend. The ejector assembly 3 is vertical. Located at the center of the rotating frame 44, after stamping is completed, the pressing component 2 retracts and resets, carrying the waste generated during stamping away from the placement cavity 53. This facilitates the subsequent cleaning of waste and removal of tubular parts by the workers, reducing the accumulation of waste inside the stamping device and its impact on subsequent operations. The ejector component 3 is activated to eject the tubular parts from the placement cavity 53, thus achieving the purpose of automatic discharge of tubular parts. This reduces the difficulty for workers to remove the tubular parts from the placement mold 42, facilitating the stamping of the next set of products and improving the production efficiency and operational safety of the stamping device.

[0028] In practical use, the operator places the tubular part into the placement cavity 53. The operator then activates the pressing component 2, which moves towards the placement cavity 53 and applies pressure to the tubular part, causing the lower end of the tubular part to fit tightly against the support component 1. The operator then activates the support component 1, which applies support force to the inner wall of the tubular part, causing the outer wall of the tubular part to fit tightly against the inner wall of the placement cavity 53. The operator then activates the stamping cylinder 43, whose telescopic end extends, causing the stamping block 47 to extend into the stamping groove 54 and stamp off the redundant part of the tubular part. The waste material generated by the stamping and cutting falls to the lower end of the pressing component 2. When the pressing component 2 retracts and resets, it causes the waste material to simultaneously detach from the placement cavity 53. The ejector component 3 is activated to push the stamped tubular part upward out of the placement cavity 53, making it easy for the operator to quickly remove the tubular part.

[0029] Combination Figure 1 , Figure 2 , Figure 3 and Figure 5 In one specific embodiment, a sliding groove 52 is horizontally provided on the fixed base 41, and the sliding groove 52 is correspondingly provided with the mounting cavity 51. Multiple sets of sliding grooves 52 are spaced around the central axis of the placement cavity 53. The support assembly 1 includes: a rotating plate 11, a motor 12, a drive gear 13, a slider 14, and a support plate 15. The rotating plate 11 is rotatably mounted on the rotating frame 44. A rack 45 is provided on the outer periphery of the rotating plate 11. A limiting groove 55 is provided on the rotating plate 11, and multiple sets of limiting grooves 55 are spaced around the central axis of the rotating plate 11. The motor 12 is vertically fixed in the mounting cavity 51. The drive gear 13 is fixedly mounted on the output end of the motor 12. The drive gear 13 meshes with the rack 45. The slider 14 is embedded in the sliding groove 52. A limiting rod 46 is vertically provided on the slider 14. The lower end of the limiting rod 46 is embedded in the limiting groove 55. One end of the support plate 15 is fixedly mounted on the side of the slider 14 near the central axis of the rotating plate 11, and the other end of the support plate 15 extends into the placement cavity 53.

[0030] In this embodiment, the rotating plate 11 is cylindrical, and its center is fitted onto the rotating groove 56. The rotation of the output end of the motor 12 drives the drive gear 13 to rotate. Because the drive gear 13 meshes with the rack 45, the rotation of the drive gear 13 drives the rotating plate 11 to rotate around the central axis of the rotating groove 56. The meshing ratio of the drive gear 13 and the rack 45 is set according to actual usage; therefore, the meshing ratio of the drive gear 13 and the rack 45 is not specifically limited in this embodiment. The rotating plate 11 is provided with multiple sets of limiting grooves 55. The limiting groove 55 is an arc-shaped groove, with one end close to the center of the rotating plate 11 and the other end close to the outer side of the rotating plate 11. The slider 14 is rectangular, the slide groove 52 is rectangular, and the limiting rod 46 is cylindrical. The upper end of the slider 14 is embedded in the slide groove 52, and the lower end of the slider 14 contacts the rotating plate 11. When the rotating plate 11 rotates, it can drive the limiting rod 46 to slide in the limiting groove 55, thereby pushing the slider 14 to make centripetal or centrifugal motion along the slide groove 52. The support plate 15 is L-shaped, and the horizontal support plate 15 is horizontal. The end and slider 14 are fixedly connected. The slider 14 and the support plate 15 can be welded, bolted, or integrally formed. No specific limitation is made in this embodiment. The vertical end of the support plate 15 extends into the placement cavity 53. When the tubular part is placed into the placement cavity 53, the lower end of the tubular part contacts the horizontal surface of the support plate 15. The support plate 15 provides vertical support for the tubular part. The arc of the side of the support plate 15 extending into the placement cavity 53 is the same as the arc of the inner wall of the placement cavity 53. When the slider 14 drives the support plate 15 to perform centrifugal motion… The arc-shaped surface of the support plate 15 is attached to the inner wall of the tubular part and a thrust is applied, thereby providing radial support force for the tubular part. The height of the upper end of the support plate 15 is flush with the height of the bottom of the stamping groove 54. When the pressing assembly 2 stamps the tubular part, the radial support force provided by the support plate 15 to the tubular part can effectively prevent the tubular part from deforming under stress. At the same time, the redundant part of the tubular part is not radially supported by the support plate 15. Therefore, the redundant part of the tubular part will be cut off when it is stamped, thereby achieving the purpose of precise stamping and cutting of the tubular part.

[0031] In practical use, the operator places the tubular part into the placement cavity 53, starts the motor 12, and the rotation of the motor 12 drives the drive gear 13 to rotate synchronously. The rotation of the drive gear 13 drives the rack 45 and the rotating plate 11 to rotate around the central axis of the rotating frame 44. The rotation of the rotating plate 11 drives the limiting rod 46 to slide in the limiting groove 55. The sliding of the limiting rod 46 drives the slider 14 and the support plate 15 to make centrifugal motion along the slide groove 52. The support plate 15 expands outward accordingly. The arc surface of the support plate 15 is in close contact with the inner wall of the tubular part and provides radial support force for the tubular part.

[0032] Combination Figure 1 , Figure 2and Figure 4 In one specific embodiment, the pressing assembly 2 includes: a mounting frame 21, a pressing cylinder 22, a connecting rod 23, a waste plate 24, a pressing plate 25, and a spring 26; the mounting frame 21 is vertically fixed on the fixed base 41, the pressing cylinder 22 is vertically fixed on the mounting frame 21, the telescopic end of the pressing cylinder 22 is correspondingly set with the placement cavity 53, the connecting rod 23 is vertically fixed on the telescopic end of the pressing cylinder 22, the waste plate 24 is horizontally fixed on the end of the connecting rod 23 away from the pressing cylinder 22, the pressing plate 25 is sleeved on the connecting rod 23, the pressing plate 25 is slidably connected to the connecting rod 23, the spring 26 is wound around the connecting rod 23, one end of the spring 26 is fixedly connected to the pressing plate 25, and the other end of the spring 26 is fixedly connected to the waste plate 24.

[0033] In this embodiment, the mounting frame 21 is an inverted U-shaped frame. The open end of the mounting frame 21 is fixedly connected to the fixed base 41. The mounting frame 21 and the fixed base 41 can be welded, bolted, or integrally formed. This embodiment does not impose specific limitations. The telescopic end of the pressing cylinder 22 is perpendicular to the fixed base 41 and points downward. The connecting rod 23 is cylindrical. The extension of the telescopic end of the pressing cylinder 22 can drive the connecting rod 23 to extend into the placement cavity 53. The scrap plate 24 is cylindrical and is fixedly set at the end of the connecting rod 23 away from the pressing cylinder 22. The scrap plate 24 and the connecting rod 23 can be welded, bolted, or integrally formed. This embodiment does not impose specific limitations. The pressing plate 25 is cylindrical. The diameter of the pressing plate 25 is the same as the diameter of the placement cavity 53. The diameter of the scrap plate 24 is the same as the inner diameter of the stamped product. When the connecting rod 23 drives the pressing plate 25 and the scrap plate... When the scrap plate 24 moves into the placement cavity 53, it extends into the interior of the tubular part. The lower pressure plate 25 contacts the end face of the tubular part. When the connecting rod 23 drives the scrap plate 24 to continue moving, the distance between the lower pressure plate 25 and the scrap plate 24 increases, causing the spring 26 to gradually stretch. Under the action of the spring 26, the lower pressure plate 25 continuously applies pressure to the top of the tubular part, making the lower end of the tubular part fit tightly with the support assembly 1, thereby ensuring that the tubular part remains stable during the stamping process. When the scrap plate 24 moves to be flush with the support plate 15, it stops moving and stamping is performed. The scrap generated by stamping falls onto the scrap plate 24. After the stamping is completed, the lower pressure cylinder 22 retracts, causing the scrap plate 24 to reset and leave the placement cavity 53, thereby achieving the purpose of separating the scrap from the tubular part, which facilitates the subsequent cleaning of the scrap and the removal of the tubular part, and reduces the accumulation of scrap inside the stamping device and its impact on subsequent operations.

[0034] In practical use, after the operator places the tubular part to be processed into the placement cavity 53, the operator starts the pressing cylinder 22. The extension end of the pressing cylinder 22 extends, driving the connecting rod 23 to move into the placement cavity 53. The connecting rod 23 drives the scrap plate 24 and the pressing plate 25 to enter the placement cavity 53 simultaneously. The pressing plate 25 is in contact with the upper end of the tubular part and cannot move. The connecting rod 23 continues to drive the scrap plate 24 to extend into the tubular part until the scrap plate 24 and the support plate 15 are at the same height. At this time, the spring 26 is gradually stretched. Under the elastic force of the spring 26, the pressing plate 25 continuously applies downward pressure to the tubular part, so that the lower end of the tubular part is tightly attached and fixed to the support assembly 1. The operator starts the stamping cylinder 43 to stamp the tubular part. The scrap generated by stamping falls onto the scrap plate 24. The operator controls the pressing cylinder 22 to retract, and the connecting rod 23 drives the scrap plate 24 to reset. The scrap plate 24 drives the scrap generated by stamping to leave the placement cavity 53.

[0035] Combination Figure 2 , Figure 3 and Figure 5 In one specific embodiment, the top material assembly 3 includes: an electric telescopic rod 31 and a top material frame 32; the electric telescopic rod 31 is vertically fixed on the rotating frame 44, the telescopic end of the electric telescopic rod 31 is correspondingly set with the placement cavity 53, and the top material frame 32 is horizontally fixed on the telescopic end of the electric telescopic rod 31.

[0036] In this embodiment, the electric telescopic rod 31 is vertically installed in the cavity of the rotating frame 44. The extension of the electric telescopic rod 31 can drive the top material frame 32 to move along the central axis of the electric telescopic rod 31 into the placement cavity 53. The top material frame 32 is rectangular and fixedly installed on the telescopic end of the electric telescopic rod 31. Multiple sets of top material frames 32 are spaced apart along the side wall of the electric telescopic rod 31, and each set of top material frames 32 is precisely embedded in the gap between two sets of support plates 15. The end of the top material frame 32 furthest from the electric telescopic rod 31 and... The inner wall of the placement cavity 53 is fitted together. After the stamping is completed, the electric telescopic rod 31 is started and gradually extends, driving multiple sets of ejector frames 32 to move upward synchronously. The ejector frames 32 pass through the gap in the support plate 15 and contact the bottom of the stamped tubular part. As the electric telescopic rod 31 continues to extend, the ejector frames 32 gradually push the tubular part out of the placement cavity 53, reducing the difficulty for workers to remove the tubular part from the placement mold 42, facilitating the subsequent stamping of the next set of products, and improving the production efficiency and operational safety of the stamping device.

[0037] In practical use, after the stamping is completed, the operator controls the electric telescopic rod 31 to extend. The extension of the electric telescopic rod 31 drives the ejector 32 to move upward. The ejector 32 passes through the gap in the support plate 15 and contacts the bottom of the tubular part, thereby ejecting the tubular part from the placement mold 42.

[0038] It should be noted that the motor 12, the stamping cylinder 43, the pressing cylinder 22, and the electric telescopic rod 31 are electrically connected to an external power source. The four-linkage stamping device is equipped with a PLC control panel 48, which is electrically connected to the motor 12, the stamping cylinder 43, the pressing cylinder 22, and the electric telescopic rod 31. The extension and retraction of the stamping cylinder 43, the pressing cylinder 22, and the electric telescopic rod 31 can be controlled through the PLC control panel 48, and the rotation of the motor 12 can also be controlled through the PLC control panel 48.

[0039] The implementation principle of this application is as follows: The operator places the tubular part to be processed into the placement cavity 53. The operator controls the extension of the pressing cylinder 22 and drives the connecting rod 23 to move into the placement cavity 53. The connecting rod 23 drives the scrap plate 24 and the pressing plate 25 to enter the placement cavity 53 simultaneously. The pressing plate 25 is in contact with the upper end of the tubular part and cannot move. The connecting rod 23 continues to drive the scrap plate 24 to extend into the tubular part until the scrap plate 24 and the support plate 15 are at the same height. At this time, the gap between the scrap plate 24 and the pressing plate 25 increases, causing the spring 26 to stretch. Under the elastic force of the spring 26, the pressing plate 25 continues to apply downward pressure to the tubular part, so that the tubular part is pressed and fixed on the horizontal end of the support plate 15. The operator starts the motor 12 and drives the drive gear 13 to rotate synchronously. The rotation of the drive gear 13 drives the rack 45 and the rotating plate 11 to rotate around the central axis of the rotating frame 44. The rotation of the rotating plate 11 drives the limit rod 46. Sliding within the limiting groove 55, the limiting rod 46 slides, causing the slider 14 and support plate 15 to move centrifugally along the slide groove 52. The support plate 15 expands outward and fits tightly against the inner wall of the tubular part, providing radial support force for the tubular part. The operator controls four sets of stamping cylinders 43 to extend and retract in batches. The extension of the stamping cylinders 43 causes the stamping block 47 to extend into the stamping groove 54 and perform stamping processing on the tubular part. The waste generated by stamping falls onto the waste plate 24. After stamping is completed, the pressing cylinder 22 retracts, causing the connecting rod 23, waste plate 24, and waste to leave from the placement cavity 53. The operator controls the rotating plate 11, slider 14, and support plate 15 to reset. The operator controls the electric telescopic rod 31 to extend. The extension of the electric telescopic rod 31 causes the ejector 32 to move upward. The ejector 32 passes through the gap in the support plate 15 and contacts the bottom of the tubular part, thereby ejecting the tubular part from the placement mold 42.
