Description

Technical Field

[0001] This invention relates to the field of stamping equipment technology, specifically to an integrated processing device for stamping parts forming and deburring. Background Technology

[0002] Stamping is a processing method that uses a stamping press and dies to apply pressure to metal or non-metal blanks, causing them to undergo plastic deformation or separation, thereby obtaining stamped parts of the desired shape and size. It is widely used in industries such as automobiles, electronics, and home appliances. Currently, in the traditional stamping process, burrs often appear on the edges of the stamped contour after the stamped parts are formed. These burrs not only affect the surface quality and dimensional accuracy of the stamped parts, but may also cause interference during subsequent assembly, and even cause scratches to operators.

[0003] In existing technologies, deburring of stamped parts typically employs separate deburring equipment, such as grinding machines and polishing machines. This requires removing the stamped parts from the press, transferring them to the deburring equipment for processing, and then collecting them after processing. This method has the following drawbacks: First, the process is cumbersome, requiring multiple transfers of the workpiece, increasing labor intensity and reducing processing efficiency. Second, during transfer, stamped parts are prone to bumps and scratches, affecting product quality. Third, separate deburring equipment requires additional investment and occupies a large area, increasing production space usage. Fourth, dust generated during deburring can easily diffuse into the processing environment, polluting it and harming the health of operators. Fifth, the transfer and collection of stamped parts largely rely on manual labor, resulting in low automation and further impacting processing efficiency. Summary of the Invention

[0004] The present invention aims to solve the problems of cumbersome processes and low automation mentioned in the background art, and provides an integrated processing device for stamping parts forming and burr removal with a simple process and a high degree of automation.

[0005] An integrated processing device for stamping and deburring includes a stamping machine body, a dust collection mechanism, a conveying mechanism, and a material collection mechanism. The stamping machine body includes a stamping die and an unloading mechanism. The stamping die includes an upper die base and a lower die base. The unloading mechanism includes an unloading plate and a deburring assembly. The unloading plate is installed at the bottom of the upper die base and rises and falls synchronously with the upper die base. The deburring assembly includes a floating mounting seat, a grinding head, and an elastic biasing component. The floating mounting seat is slidably installed on the unloading plate in a vertical direction, with its lower end extending below the unloading plate and aligned with the blanking contour of the stamped part. The grinding head is installed on the floating mounting seat, and the elastic biasing component is installed between the floating mounting seat and the unloading plate. The dust collection mechanism is located on the stamping machine body, the conveying mechanism is located on the discharge side of the stamping machine body, and the material collection mechanism is located below the discharge end of the conveying mechanism.

[0006] The stamping press body is the core component of the device. The frame is made of welded steel structure, possessing sufficient strength and rigidity to withstand the impact loads during the stamping process. The stamping drive mechanism uses hydraulic drive or servo motor drive, providing precise position and pressure control. The upper and lower dies are designed according to the shape and size of the workpiece and are made of high-strength die steel, which, after heat treatment, has high hardness and wear resistance. By integrating the deburring components into the unloading mechanism, stamping and deburring are performed simultaneously. Utilizing the movement of the unloading plate itself, combined with the floating mounting base and elastic biasing component, the grinding head can be positioned during unloading. While pressing the strip, the grinding head contacts the edge of the stamped part with a certain pressure for grinding. No additional drive source or complex control system is required. The setting of the elastic bias component ensures that the grinding head can always keep in contact with the surface of the stamped part, adapting to stamped parts of different thicknesses or with slight dimensional deviations. This improves the consistency and thoroughness of burr removal, while avoiding damage to the surface of the stamped part caused by rigid contact. The coordinated setting of the dust collection mechanism, conveying mechanism and material collection mechanism realizes the automation of dust collection, workpiece conveying and centralized material collection during the processing. The structure is simple, the cost is low and the degree of automation is high; thus achieving the goal of simple process and high degree of automation.

[0007] Preferably, the stripper plate has a stepped mounting hole that extends vertically through it, and the floating mounting seat is a stepped shaft structure adapted to the mounting hole. The floating mounting seat has a first position under the action of the elastic biasing member, and a second position that retracts upward relative to the stripper plate during die closing and stamping, overcoming the elastic force of the elastic biasing member. The stepped mounting hole is compatible with the floating mounting seat of the stepped shaft structure, which not only enables the floating mounting seat to slide stably in the vertical direction, but also limits the sliding stroke of the floating mounting seat, avoiding structural damage or poor burr treatment due to excessive sliding. The design of the first position (under the action of the elastic bias member) and the second position (retracted during die-forming and stamping) of the floating mounting seat allows the device to flexibly adapt to different working conditions of stamping and burr treatment: during die-forming and stamping, the floating mounting seat retracts to avoid the grinding head interfering with the stamping process; after stamping, the floating mounting seat returns to its original position under the action of the elastic bias member, and the grinding head adheres to the stamped part for burr treatment, ensuring that stamping and burr treatment do not interfere with each other and work together efficiently; the stepped shaft structure of the floating mounting seat also enhances structural stability, reduces shaking during sliding, ensures the positioning accuracy of the grinding head, and improves the quality of burr treatment.

[0008] Preferably, the top of the unloading plate has a limiting hole, and a limiting component is installed in the limiting hole. The limiting hole is coaxial with the small-diameter section of the mounting hole and its diameter is larger than the outer diameter of the limiting component. The top of the floating mounting base is provided with a guide pin. The lower end of the guide pin is fixedly connected to the top of the floating mounting base, and the upper end is slidably inserted into the small-diameter section of the mounting hole and connected to the limiting component. The elastic biasing component is a compression spring, which is sleeved on the outer periphery of the guide pin, and its two ends abut against the top end face of the mounting hole and the top end face of the floating mounting base, respectively. The setting of limiting holes and limiting components further limits the maximum reset stroke of the floating mounting seat, preventing excessive downward movement of the floating mounting seat due to excessive elastic force of the elastic biasing component, thereby preventing excessive extrusion of the grinding head and the stamping part, which would cause surface damage. The setting of the guide pin provides precise guidance for the vertical sliding of the floating mounting seat, preventing offset and jamming during the sliding process. The elastic biasing component uses a compression spring and is sleeved on the outer periphery of the guide pin to ensure stable pressure between the grinding head and the stamping part, providing stable preload force, allowing the grinding head to retract smoothly when the mold is closed, avoiding rigid interference with the mold, and improving the stability and reliability of the device.

[0009] Preferably, the grinding head is detachably connected to the floating mounting base via a dovetail joint structure. The floating mounting base has a set screw hole on its side, and a set screw is installed within the set screw hole. The inner end of the set screw abuts against the side of the grinding head, achieving a locking and fixing effect between the grinding head and the floating mounting base. The unloading plate has an operating window corresponding to the position of the set screw hole, and the size of the operating window is larger than the head size of the set screw. The grinding head uses a dovetail joint structure and lateral set screw locking, achieving a quick and stable detachable connection. The operating window makes it convenient and quick to replace worn grinding heads in confined spaces, greatly reducing maintenance difficulty and downtime.

[0010] Preferably, multiple deburring components are provided, spaced apart along the blanking contour edge of the stamped part at intervals of 5-15mm to accommodate the deburring requirements of stamped parts of different sizes. The preload provided by the elastic biasing component is 50-150N, which is less than the preload of the stripper plate and greater than the sum of the weights of the grinding head and its connected floating mounting base. The arrangement of multiple deburring components along the blanking contour ensures that burrs on the entire edge of the workpiece can be effectively processed without leaving any blind spots. The 5-15mm spacing can cover most small and medium-sized stamped parts. The optimized 50-150N preload ensures sufficient grinding pressure to remove burrs without damaging the workpiece surface or causing abnormal operation of the stripper plate due to excessive pressure, and also ensures that the grinding head always remains in contact with the workpiece.

[0011] Preferably, the dust collection mechanism includes a dust collection hood, a dust collection pipe, and a negative pressure fan. The dust collection hood is located below the unloading plate and surrounds the outer periphery of the grinding head. The negative pressure fan is linked to the control system of the press body and is installed beside the press body. A dust collection pipe interface is located on the upper part of the outer wall of the dust collection hood. One end of the dust collection pipe is sealed to the dust collection pipe interface via a hose clamp, and the other end is sealed to the air inlet of the negative pressure fan via a hose clamp. The dust collection pipe is a telescopic corrugated pipe with a natural length greater than the maximum stroke of the unloading plate and a 10-20mm extension allowance to prevent interference between the unloading plate and the dust collection pipe during lifting and lowering. The linkage between the dust collection mechanism and the press control system enables immediate and automatic collection of dust generated during grinding, significantly improving the working environment and protecting the health of operators. The design of the telescopic corrugated pipe adapts to the reciprocating motion of the unloading plate, ensuring the dust collection channel remains unobstructed and reliably connected. The reserved extension allowance prevents the pipe from being stretched and damaged during movement.

[0012] Preferably, the dust hood is made of elastic soft plastic material and includes an integrally formed fixed flange, a compressible corrugated part, and a sealing skirt. The fixed flange is the top of the dust hood and is fixedly connected to the bottom surface of the unloading plate by bolts. The corrugated part is the middle part of the dust hood and is an axially expandable corrugated tube structure that adapts to the lifting and lowering movement of the unloading plate. The sealing skirt is the bottom of the dust hood and is a downwardly extending flexible annular sheet with a serrated lower edge that can tightly fit the surface of the stamped part. The inner diameter of the dust hood is larger than the outer diameter of the floating mounting base, with a 2-5mm annular gap between them. The dust hood, made of flexible soft plastic material, is soft and adaptable to the lifting and lowering movement of the unloading plate. Its one-piece molding structure ensures good integrity and strong sealing. The fixed flange ensures the stability of the connection, while the compressible corrugated part can freely expand and contract with the lifting and lowering of the unloading plate without affecting the movement of the equipment. The serrated edge of the sealing skirt can closely fit the surface of stamped parts of various shapes to form a local sealing space, which greatly improves the dust collection efficiency and prevents dust from escaping. The annular gap ensures that the free movement of the floating mounting base is not interfered with.

[0013] Preferably, the conveying mechanism includes a conveyor belt disposed on the discharge side of the lower die base. Guide baffles are provided on both sides of the conveyor belt. The material collection mechanism includes a blanking plate, a collection box, and a buffer base plate. One end of the blanking plate is connected to the discharge end of the conveyor belt, and the other end is inclined downwards and connected to the collection box. The buffer base plate is floatingly installed at the bottom of the collection box, and a buffer spring is installed below it. The conveyor belt smoothly delivers the processed stamped parts from the stamping area. The guide baffles prevent the workpieces from falling during the conveying process. The buffer base plate and buffer spring of the collection box can effectively absorb the impact force when the workpieces fall, preventing the workpieces from being damaged due to collision and ensuring the quality of the finished product.

[0014] Preferably, the blanking plate has an arc-shaped structure, with staggered buffer strips on its inner surface. These buffer strips are made of rubber and are bonded to the blanking plate using a high-strength adhesive. The arc-shaped blanking plate slows down the downward movement of the workpiece, and the staggered rubber buffer strips further decelerate and cushion the movement, allowing the workpiece to slide into the collection box at a lower speed and with less impact. This design is particularly suitable for stamped parts with high surface quality requirements or those prone to scratches, effectively protecting the product's appearance.

[0015] Preferably, the material collection bin is equipped with a full-load alarm device, which includes a photoelectric switch and an alarm light. The photoelectric switch is fixedly installed on the upper inner wall of the material collection bin and electrically connected to the alarm light. When the workpiece accumulation height in the material collection bin triggers the photoelectric switch, the alarm light will sound an alarm, reminding the operator to clean it in time. This effectively avoids workpiece overflow, blockage, or damage caused by the material collection bin being too full, and realizes unattended or minimally-attended automated production.

[0016] The beneficial effects of this invention are as follows: Integrated operation, combining deburring with the stamping unloading plate, achieves simultaneous and in-situ completion of punching and deburring, improving production efficiency; the floating grinding head driven by an elastic bias component can adaptively conform to the workpiece contour, removing burrs with constant pressure, ensuring stable and reliable processing quality; the dust collection mechanism linked to the stamping action efficiently collects dust through a specially designed flexible dust hood during grinding, improving the workshop working environment and protecting the health of operators; high degree of automation, forming a complete automated production line from stamping, deburring, dust collection to conveying and material collection; the buffer design and full material alarm function of the material collection box ensure the continuity and stability of production, reducing manual intervention; the grinding head can be quickly disassembled and assembled using dovetail joints and set screws, and the operation window design allows for replacement and maintenance without complex disassembly, reducing maintenance difficulty and time costs; achieving the goals of simplified process and high degree of automation.

Therefore, they should not be construed as limiting this invention.

[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; or they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] Furthermore, in the description of this invention, unless otherwise stated, "multiple", "multiple groups", and "multiple roots" mean two or more.

[0023] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments; like Figure 1 and Figure 2As shown, an integrated processing device for stamping parts forming and deburring includes a stamping machine body 1, a dust collection mechanism 4, a conveying mechanism 5, and a material collection mechanism 6. The stamping machine body 1 adopts the existing conventional stamping machine structure, and its core includes a stamping die 2 and an unloading mechanism 3. The stamping die 2 includes an upper die holder 21 and a lower die holder 22. The upper die holder 21 is connected to the power output end of the stamping machine and can be raised and lowered in the vertical direction. The lower die holder 22 is fixedly installed on the worktable of the stamping machine body 1. The upper die holder 21 and the lower die holder 22 cooperate to realize the stamping forming of sheet metal.

[0024] like Figure 3 As shown, the unloading mechanism 3 includes an unloading plate 31 and a deburring assembly 32. The unloading plate 31 is bolted to the bottom of the upper die base 21 and rises and falls synchronously with the upper die base 21. The bottom surface of the unloading plate 31 corresponds to the top surface of the lower die base 22, and is used to unload the workpiece from the lower die base 22 after stamping. Figure 4 As shown, multiple burr treatment components 32 are provided, and the multiple burr treatment components 32 are arranged at intervals along the blanking contour edge of the stamped part, with a spacing of 10mm, to meet the burr treatment requirements of medium-sized stamped parts. Each burr treatment component 32 includes a floating mounting base 321, a grinding head 323, and an elastic biasing component 322. The stripper plate 31 has a stepped mounting hole 313 that runs vertically through it. The floating mounting base 321 is a stepped shaft structure that matches the mounting hole 313 and can be slidably installed in the mounting hole 313 of the stripper plate 31 in the vertical direction. The lower end of the floating mounting base 321 extends to the bottom of the stripper plate 31 and is aligned with the blanking contour of the stamped part. The grinding head 323 is installed at the lower end of the floating mounting base 321. The grinding surface of the grinding head 323 matches the blanking contour of the stamped part. A diamond grinding head 323 is used, which has high hardness, strong wear resistance, and good grinding effect.

[0025] like Figure 3 and Figure 4As shown, the elastic biasing component 322 is a compression spring, which provides a preload of 100N. This preload is less than the preload of the unloading plate 31 (the preload of the unloading plate 31 is set to 200N) and greater than the sum of the weights of the grinding head 323 and its connected floating mounting base 321 (the total weight is about 80N). This ensures that the grinding head 323 always remains extended in the non-pressing state and can retract smoothly during pressing. The top of the unloading plate 31 has a limiting hole 311, and a limiting component 312 (using a limiting nut) is installed in the limiting hole 311 by threaded connection. The limiting hole 311 is coaxial with the small diameter section of the mounting hole 313 and its diameter is larger than the outer diameter of the limiting component 312. The top of the floating mounting base 321 is integrally formed with a guide pin 324. The lower end of the guide pin 324 is fixedly connected to the top of the floating mounting base 321, and the upper end is slidably inserted into the small diameter section of the mounting hole 313 and threadedly connected to the limiting component 312. A compression spring is sleeved on the outer periphery of the guide pin 324, and its two ends abut against the top end face of the mounting hole 313 and the top end face of the floating mounting base 321, respectively, to realize the elastic floating of the floating mounting base 321.

[0026] like Figure 3 As shown, the grinding head 323 is detachably connected to the floating mounting base 321 via a dovetail tenon structure. The lower side of the floating mounting base 321 has a set screw hole 3211, and a set screw 3212 is provided in the set screw hole 3211. The inner end of the set screw 3212 abuts against the side of the grinding head 323 to lock and fix the grinding head 323 to the floating mounting base 321. The unloading plate 31 has an operation window 314 at the position corresponding to the set screw hole 3211. The size of the operation window 314 is larger than the head size of the set screw 3212, so that the operator can turn the set screw 3212 through the operation window 314 to complete the assembly and disassembly of the grinding head 323.

[0027] like Figure 5 and Figure 6 As shown, the dust collection mechanism 4 includes a dust collection hood 41, a dust collection pipe 42, and a negative pressure fan 43. The dust collection hood 41 is located below the unloading plate 31 and surrounds the outer periphery of each grinding head 323. The dust collection hood 41 is made of elastic soft plastic material (such as PVC soft plastic) and includes an integrally formed fixed flange part 411, a compressible corrugated part 412, and a sealing skirt part 413. The fixed flange part 411 is the top of the dust collection hood 41 and is fixedly connected to the bottom surface of the unloading plate 31 by bolts; the corrugated part 412... 12 is the middle part of the dust hood 41, which is an axially extendable corrugated pipe structure that is adapted to the lifting and lowering movement of the unloading plate 31; the sealing skirt 413 is the bottom of the dust hood 41, which is a downwardly extending flexible annular sheet with a serrated lower edge, which can tightly fit the surface of the stamped part and reduce dust leakage; the inner diameter of the dust hood 41 is larger than the outer diameter of the floating mounting base 321, and there is a 3mm annular gap between the two, which facilitates the entry of dust into the dust hood 41 without affecting the lifting and lowering of the floating mounting base 321.

[0028] The negative pressure fan 43 is linked to the control system of the press body 1 and is installed on the side of the press body 1. The upper part of the outer wall of the dust collection hood 41 is provided with a dust collection pipe interface 414. The dust collection pipe 42 is a telescopic corrugated pipe with a natural length greater than the maximum stroke of the unloading plate 31 (the maximum lifting stroke of the unloading plate 31 is 100mm, and the natural length of the corrugated pipe is 120mm). A 15mm extension margin is reserved to avoid interference between the unloading plate 31 and the dust collection pipe 42 when the unloading plate 31 is lifted or lowered. One end of the dust collection pipe 42 is sealed to the dust collection pipe interface 414 through a hose clamp, and the other end is sealed to the air inlet of the negative pressure fan 43 through a hose clamp. The air outlet of the negative pressure fan 43 is connected to a dust collection bag for collecting dust and burr debris.

[0029] like Figure 1 As shown, the conveying mechanism 5 includes a conveyor belt 51, which is a belt-type conveyor belt and is set on the discharge side of the lower die base 22. The top surface of the conveyor belt 51 is flush with the top surface of the lower die base 22, so that the workpiece can fall smoothly into the conveyor belt 51. Guide baffles 52 are fixed on both sides of the conveyor belt 51 by brackets. The guide baffles 52 are set along the length of the conveyor belt 51, and the spacing is adapted to the width of the stamping part to prevent the workpiece from shifting or falling during the conveying process.

[0030] like Figure 1 and Figure 7 As shown, the material collection mechanism 6 includes a drop plate 61, a collection box 62, and a buffer base plate 63. The drop plate 61 has an arc-shaped structure; one end is connected to the discharge end of the conveyor belt 51 by bolts, and the other end is inclined downwards and connected to the inlet of the collection box 62 at an angle of 30° to facilitate the sliding of the workpiece. Buffer strips 611 are staggered on the inner surface of the drop plate 61. The buffer strips 611 are made of rubber, 5mm thick, and are bonded to the drop plate 61 with a high-strength adhesive (such as epoxy adhesive) to enhance the buffering effect. Figure 8 As shown, the buffer base plate 63 is floatingly installed at the bottom of the collection box 62, and four buffer springs 64 are evenly installed below it. The two ends of the buffer springs 64 are fixedly connected to the bottom surface of the buffer base plate 63 and the bottom inner wall of the collection box 62, respectively, to buffer the falling workpiece and prevent the workpiece from deforming.

[0031] like Figure 8 As shown, a full material alarm device is installed inside the material collection box 62. The full material alarm device includes a photoelectric switch 621 and an alarm light 622. The photoelectric switch 621 is fixedly installed on the upper part of the inner side wall of the material collection box 62 by a bracket. The height of the photoelectric switch 621 from the bottom of the material collection box 62 is 80% of the volume of the material collection box 62. The photoelectric switch 621 is electrically connected to the alarm light 622. The alarm light 622 is installed on the top of the material collection box 62. When the workpieces accumulate to the detection position of the photoelectric switch 621, the photoelectric switch 621 triggers the alarm light 622 to light up, reminding the operator to clean it. Example 2

[0032] The difference between this embodiment and Embodiment 1 is as follows: the spacing of the burr treatment components 32 is 5mm, which is suitable for the burr treatment requirements of small-sized stamped parts; the preload provided by the elastic bias component 322 is 50N, the preload of the unloading plate 31 is set to 150N, and the total weight of the grinding head 323 and its connected floating mounting base 321 is about 40N; the natural length of the dust suction pipe 42 is 10mm greater than the maximum travel of the unloading plate 31, leaving a 10mm extension allowance; the annular gap between the dust suction hood 41 and the floating mounting base 321 is 2mm; the tilt angle of the unloading plate 61 is 25°, and the thickness of the buffer strip 611 is 3mm; the height of the photoelectric switch 621 from the bottom of the collection box 62 is 75% of the volume of the collection box 62. The rest of the structure is the same as in Embodiment 1. Example 3

[0033] The difference between this embodiment and Embodiment 1 is as follows: the spacing of the deburring components 32 is 15mm, which is suitable for the deburring requirements of large-sized stamped parts; the preload provided by the elastic bias component 322 is 150N, the preload of the unloading plate 31 is set to 250N, and the total weight of the grinding head 323 and its connected floating mounting base 321 is about 120N; the natural length of the dust suction pipe 42 is 15mm greater than the maximum travel of the unloading plate 31, with a 20mm extension allowance; the annular gap between the dust suction hood 41 and the floating mounting base 321 is 5mm; the tilt angle of the unloading plate 61 is 35°, and the thickness of the buffer strip 611 is 7mm; the height of the photoelectric switch 621 from the bottom of the collection box 62 is 85% of the volume of the collection box 62. The rest of the structure is the same as in Embodiment 1.

[0034] All three embodiments above can achieve integrated processing of stamping and deburring. The spacing of the deburring component 32 and the preload of the elastic bias component 322 can be adjusted according to the size and material requirements of the stamped parts to adapt to different processing needs. All of them have automated dust collection, conveying and material collection functions, resulting in high processing efficiency, good product quality and a friendly working environment.

[0035] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications and equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the claims of the present invention.
