Description

Technical Field

[0001] The present application relates to the field of component production, and in particular to a punching structure of a high-strength component. Background Art

[0002] With the rapid development of the high-end equipment manufacturing industry, the demand for high-strength, high-precision, and high-reliability components is growing. These components need to withstand greater mechanical stress and environmental challenges, so the design and optimization of punching structures have become particularly important. Punching is a common process in the processing of metal sheets and pipes. A through-hole is machined into the material using a stamping die. However, existing stamping dies usually use a punching rod to directly apply pressure to the material surface to create a puncture effect and complete the punching. However, when the punching rod pierces the material surface, it is easy to leave sharp protrusions on the material surface, which affects the subsequent assembly fit. In addition, the inner wall of the punching hole is in a vertical channel, which is prone to loosening when assembled with the butt end. Utility Model Content

[0003] In order to improve the problem that conventional punching structures are prone to leaving sharp protrusions and vertical channels lead to poor assembly stability, the present application provides a punching structure for high-strength components.

[0004] The punching structure of a high-strength component provided in this application adopts the following technical solution:

[0005] A punching structure for a high-strength component comprises a base, a support plate fixedly provided on the top of the base, a pressure plate connected to the top of the support plate for receiving gravity, multiple rows of T-shaped limit grooves are formed on the surface of the pressure plate, longitudinal bars and pressure bars are sequentially provided on the tops of the multiple rows of limit grooves, T-shaped abutment modules are provided in the multiple rows of limit grooves, the T-shaped protrusions of the multiple abutment modules are all engaged with the T-shaped inner walls of the multiple limit grooves, and a through hole with the same width as the longitudinal bar is formed in the middle of the abutment module;

[0006] The ends of the plurality of pressure rods close to the abutment modules are each provided with a protrusion for shaping the necking, the bottom of the protrusion being arranged in an arc shape, and the surfaces of the plurality of abutment modules located on the pressure rods are provided with a concave surface for releasing the pressure of the material plate, and the concave surface is matched with the arc shape of the bottom of the protrusion;

[0007] A limiting plate is arranged around the outer surface of the multiple pressure rods, a mounting layer is arranged on the top of the limiting plate, a telescopic mechanism is arranged on the top of the mounting layer at the position of the multiple pressure rods, and multiple push rods at the bottom of the telescopic mechanism are movable through the mounting layer and fixed one by one to the multiple pressure rods.

[0008] By adopting the above technical solution, the longitudinal rod and the pressure rod respectively punch holes in the material sheet, so that the inner wall of the punching hole on the surface of the material sheet forms a trapezoid for easy assembly. At the same time, the abutment module is located at the bottom of the punching position of the material sheet, thereby receiving the pressure on the material sheet and effectively preventing the material sheet from being deformed due to pressure.

[0009] Preferably, a connecting plate is fixed to the bottom of the pressure plate, the bottom of the connecting plate is fixed to the support plate, and connecting holes are opened on the surface of the connecting plate at the positions of multiple rows of limiting grooves, and the multiple rows of connecting holes are connected to the multiple rows of limiting grooves one by one.

[0010] By adopting the above technical solution, the connecting hole is connected to the limiting groove, thereby reserving space for the insertion of the longitudinal rod, and at the same time receiving the debris dropped from the opening and discharging it to the outside of the device.

[0011] Preferably, a support beam is fixedly provided on the top of the installation layer between the multiple telescopic mechanisms, and a top cover is fixedly connected to the top of each of the multiple support beams.

[0012] By adopting the above technical solution, the support beam connects the installation layer and the top cover, and the top cover is connected to the external wall, so that the installation layer, the limit plate and the wall are fixed as a whole, forming a gap between the limit plate and the pressure plate, which facilitates the movement of materials into the gap for punching.

[0013] Preferably, the bottom of the limiting plate is provided with an interactive opening at the position of the limiting groove.

[0014] By adopting the above technical solution, the interactive port is aligned with the center of the limiting groove, and the bottom of the pressure rod is pressed out by the interactive port to perform a punching process on the material.

[0015] Preferably, T-shaped slots are provided at the bottom of the installation layer at the position of the interaction port, and the tops of the plurality of pressure rods are sequentially inserted through the interaction port and the T-shaped slots and fixedly connected to the push rod of the telescopic mechanism.

[0016] By adopting the above technical solution, the T-slot is connected to the interactive port, thereby reserving space for the insertion of the pressure rod. At the same time, the inner wall of the T-slot limits the top of the pressure rod to prevent the pressure rod from moving excessively and sliding out of the installation layer.

[0017] Preferably, the installation layer is composed of a plurality of installation plates spliced ​​together, and a fixing plate for fixing the plurality of installation plates is fixed on one side surface of the installation layer.

[0018] By adopting the above technical solution, multiple mounting plates form the mounting layer, thereby providing a penetration space for the push rod of the telescopic mechanism.

[0019] Preferably, a material plate is movably arranged between the pressure plate and the limiting plate, and one end of the material plate is connected to a transmission mechanism.

[0020] By adopting the above technical solution, the transmission mechanism pushes the material plate to move horizontally, so that the material plate moves between the pressure plate and the limit plate, and is pressed and penetrated by the pressure rod and the longitudinal rod to form a punching effect.

[0021] Preferably, the surface of the support plate is provided with discharge holes at the positions of the plurality of limit grooves, and the surface of the base is provided with a discharge port within the range of the plurality of discharge holes.

[0022] By adopting the above technical solution, the discharge hole and the connection hole are docked, thereby receiving the miscellaneous materials dropped from the limiting groove and discharging the miscellaneous materials to the outside through the discharge port.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Use the longitudinal rod to press down the material sheet to punch, and then the pressure rod performs secondary crimping on the punching position, so that the protrusion abuts against the inner wall of the punching to form a trapezoidal inner wall, which effectively improves the stability of the assembly with the external interface. While the material sheet receives the downward pressure, the abutment module is located at the bottom of the punching position of the material sheet, thereby providing upward support force to the material sheet to prevent the material sheet from deforming and producing spikes.

[0032] The following is combined with Figures 1-6 This application is described in further detail.

[0033] An embodiment of the present application discloses a punching structure for a high-strength component.

[0034] The "up, down, left, right" viewing angles of this device are Figure 3 The directions in the attached drawings are for reference only.

[0035] Reference Figure 1 、 Figure 2 、 Figure 3 A punching structure for high-strength components includes a base 1, the upper end surface of the base 1 is fixedly connected to a support plate 2 through multiple columns, the width of the support plate 2 is consistent with the base 1, a connecting plate 3 is fixedly provided at the middle position of the upper end surface of the support plate 2 by screws, and a pressure plate 4 is fixedly provided on the upper end surface of the connecting plate 3 by screws, and the width of the pressure plate 4 is consistent with the connecting plate 3, and a limiting plate 5 is fixedly provided on the top of the pressure plate 4. The upper end surface of the limiting plate 5 is fixedly connected to a mounting layer 6, and the upper end surface of the mounting layer 6 is fixed with multiple support beams 8 (the number of support beams 8 is adjusted according to the actual width of the base 1), and the upper end surfaces of the multiple support beams 8 are fixedly connected with top covers 9 with screws, and the top of the top cover 9 is fixedly connected to the external wall. At the same time, the mounting layer 6 is composed of multiple mounting plates spliced ​​together, and fixing plates 7 are fixed with screws on the side surfaces of the mounting plates at the upper and lower ends, so that the mounting plates at the upper and lower ends clamp and fix the internal mounting plates.

[0036] It should be noted that the pressure plate 4 is integrally connected to the base 1 and is located at the lower part, and the limit plate 5 is integrally connected to the top cover 9 and is located at the upper part, so that the pressure plate 4 and the limit plate 5 are separated as a whole and there is an interlaced space, and a material plate 16 is movably interlaced in the interlaced space, and the material plate 16 is located at one end of the outside and is docked with a transmission mechanism, thereby pushing the material plate 16 to move between the pressure plate 4 and the limit plate 5.

[0037] The pressure plate 4 is fixed to the connecting plate 3 by screws, and the connecting plate 3 is fixed to the support plate 2 by screws, and the connection relationship between the support plate 2 and the base 1 is fixed, forming an effect that the pressure plate 4 and the base 1 are fixed to the bottom as a whole. At the same time, the limit plate 5 is fixed to the mounting layer 6 by screws, and the mounting layer 6 is fixed to the top cover 9 by screws, forming an effect that the limit plate 5 and the top cover 9 are fixed as a whole, and the top cover 9 is installed on the top of the external wall, so that the limit plate 5 is at the top and the pressure plate 4 is at the bottom, so that punching space is directly reserved for the pressure plate 4 and the limit plate 5.

[0038] Reference Figure 2 、 Figure 4 、 Figure 6The upper end surface of the mounting layer 6 is located between multiple support beams 8 and a telescopic mechanism 15 is fixed thereon. The push rod parts of multiple telescopic mechanisms 15 movably penetrate the bottom of the mounting layer 6, and the bottom of the mounting layer 6 is provided with a T-slot 19 at the penetration position of multiple push rods. The bottom of the T-slot 19 is in a shrinking state. At the same time, the position of the limit plate 5 at the T-slot 19 is provided with an interactive opening 18, wherein a longitudinal rod 21 is inserted into the interactive opening 18 of the left part, and a pressure rod 14 is inserted into the interactive opening 18 of the right part. A protrusion 20 is provided at the bottom of the pressure rod 14, and the surface of the protrusion 20 is set as an arc surface. The longitudinal rod 21 and the top of the pressure rod 14 are both inserted into the T-slot 19 through the interactive opening 18, and the longitudinal rod 21 and the top of the pressure rod 14 are both provided with an annular protrusion, which abuts against the flared opening of the T-slot 19 to form a limit, and the push rods of multiple telescopic mechanisms 15 all penetrate the bottom of the mounting layer 6 and are fixed to the longitudinal rod 21 and the pressure rod 14.

[0039] The push rod of the telescopic mechanism 15 is pressed downward to drive the longitudinal rod 21 and the pressure rod 14 to move downward. When the longitudinal rod 21 and the pressure rod 14 move, they penetrate the bottom of the limit plate 5 from the T-slot 19 to the interactive port 18, and the annular protrusions on the surface of the longitudinal rod 21 and the pressure rod 14 are engaged with the shrinkage in the T-slot 19, thereby preventing the longitudinal rod 21 and the pressure rod 14 from falling to the outside, limiting the movement of the longitudinal rod 21 and the pressure rod 14, and as the longitudinal rod 21 descends, pressure is applied to the surface of the material sheet 16 to perform preliminary punching, and then the material sheet 16 moves to align the punching with the bottom of the pressure rod 14, and as the pressure rod 14 is pressed downward, the protrusion 20 is pressed into the punching, so that the punching forms a stepped inner wall.

[0040] Reference Figure 2 、 Figure 3 、 Figure 5 , the upper end surface of the pressure plate 4 is provided with a limiting groove 12 at the position of the interactive port 18, and abutment modules 13 are fixed in the multiple limiting grooves 12. The abutment module 13 is T-shaped as a whole and has a through hole in the middle. The top surfaces of the multiple abutment modules 13 located at the bottom of the pressure rod 14 are all provided with grooves inward, and the grooves fit with the arc surface of the protrusion 20. At the same time, the surface of the connecting plate 3 is aligned with the position of the through hole of the abutment module 13 and a connecting hole 11 is provided, and the surface of the support plate 2 is provided with a discharge hole 10 at the position of the multiple connection holes 11. The discharge hole 10, the connection hole 11, the through hole of the abutment module 13 and the limiting groove 12 are all in a center-aligned state. The surface of the base 1 is provided with a discharge port 17 at the position of the discharge hole 10, and a storage structure is prevented at the bottom of the discharge port 17.

[0041] It should be noted that the inner wall of the limiting groove 12 is T-shaped, and the outer surface of the abutment module 13 is protruded with a T-shaped protrusion that engages with the inner wall of the limiting groove 12, so that the abutment module 13 is fixed in the limiting groove 12 to form a snap connection, thereby improving stability.

[0042] When the pressure rod 14 and the longitudinal rod 21 respectively press down on the material sheet 16 to punch holes, the upper end surface of the abutment module 13 is located at the bottom of the material sheet 16, thereby providing support force for the punching surface position of the material sheet 16, thereby preventing the surface of the material sheet 16 from being deformed due to the downward pressure. At the same time, the through hole in the middle of the abutment module 13 is connected with the connecting hole 11, so that the miscellaneous materials separated by the punching fall into the discharge hole 10 from the connecting hole 11, and are discharged to the outside through the discharge port 17, preventing the miscellaneous materials from remaining and interfering with the subsequent welding process. Moreover, when the pressure rod 14 performs secondary processing on the punching, the groove on the surface of the abutment module 13 receives the pressure applied by the pressure rod 14 and provides deformation space for the trapezoidal inner wall opened by the material sheet 16.

[0043] The implementation principle of the punching structure of a high-strength component in the embodiment of the present application is as follows: when using this device, it is necessary to start the external conveying mechanism, and the conveying mechanism drives the material plate 16 to move between the pressure plate 4 and the limit plate 5. When the material plate 16 moves to the bottom of the longitudinal rod 21, the conveying mechanism stops running, and the personnel controls the operation of the telescopic mechanism 15 through the microcomputer. The push rod of the telescopic mechanism 15 drives the longitudinal rod 21 to press down, thereby performing a preliminary penetration through the surface of the material plate 16. At the same time, the surface of the material plate 16 located at the opening is supported upward by the abutment module 13, so that the surface of the material plate 16 remains horizontal, avoiding the material plate 16 from being deformed by pressure, thereby generating spikes. At the same time, the debris produced by the penetration falls into the connecting hole 11 from the through hole in the middle of the abutment module 13, and is discharged to the outside from the discharge hole 10 to the discharge port 17, avoiding the residual debris affecting the subsequent welding and assembly processes.

[0044] After the initial opening of the material sheet 16, the conveying mechanism continues to drive the material sheet 16 to move. When the opening of the material sheet 16 moves to align with the pressure rod 14, the microcomputer controls the telescopic mechanism 15 to operate, so that the push rod of the telescopic mechanism 15 drives the pressure rod 14 to press down. When the pressure rod 14 is pressed into the opening surface of the material sheet 16, the protrusion 20 is pressed into the inside of the opening, forming the surface of the protrusion 20 and the bottom surface of the pressure rod 14, which respectively apply pressure to the inside and surface of the hole of the material sheet 16, thereby crimping the opening of the material sheet 16 into a trapezoidal state, and when the material sheet 16 is squeezed by pressure, the groove of the abutment module 13 provides space for the deformation of the material sheet 16, and the pressure of the material sheet 16 is effectively released.

[0045] The above are merely optional embodiments of the present disclosure and are not intended to limit the present disclosure. Those skilled in the art will readily appreciate that the present disclosure may be modified and varied in various ways. Any modifications, equivalent substitutions, improvements, and the like made within the spirit and principles of the present disclosure shall be included within the scope of protection of the present disclosure.
