Description

Technical Field

[0001] The present invention relates to the technical field of aluminum casing processing equipment, in particular to an aluminum casing stamping continuous production device and its use method. Background Art

[0002] An aluminum casing is a product used for automotive air suspension. During the manufacturing process of the aluminum casing, a coil material needs to be pre-stamped into round sheets by a continuous punching machine, and then the round sheets are fed into a continuously forming punching machine, so that the punching machine stamps the round sheets into aluminum casings.

[0003] In the prior art, semi-finished material sheets are first produced by a small-tonnage single-stamping die punching machine, and then the material sheets are transferred to a large-tonnage continuous die punching machine for secondary stamping and forming. The existing production method has at least the following disadvantages:

[0004] 1) The single-stamping die and the continuous die are not connected in production, and the semi-finished material sheets produced need to be transferred, which is time-consuming, laborious and increases the labor cost;

[0005] 2) In order to save raw materials, a material tape yawing machine is used in cooperation with the single-stamping die punching machine. However, the material tape yawing machine exists as an independent device and occupies a certain amount of floor space. Especially in the case of limited space, it is difficult to arrange the yawing machine;

[0006] 3) Before continuous die stamping and forming, oil is applied to the surface of the material sheet by manual using brushing tools such as brushes and rollers, and then manual feeding is carried out. The efficiency is low, and it cannot effectively match the subsequent continuous stamping rhythm, and the amount of oil used cannot be effectively controlled, which easily leads to excessive oil application resulting in waste or insufficient oil affecting stamping. Summary of the Invention

[0007] To solve the above problems, the present invention provides an aluminum casing stamping continuous production device with a reasonable structure and its use method, which realizes the continuous automated production of aluminum casing stamping, eliminates the arrangement of the yawing machine, effectively integrates the yawing performance to ensure the high utilization rate of the material tape, thereby effectively reducing the floor area, eliminating material turnover, greatly helping to reduce costs, and helping to improve the forming efficiency of the aluminum casing and ensure the forming effect.

[0008] The technical solution adopted by the present invention is as follows:

[0009] An aluminum casing stamping continuous production device, the continuous production device is integrally arranged in an L-shaped structure, including a single punching machine located at the corner. Along the X direction on the feeding side of the single punching machine, a leveling machine and a feeder are arranged in sequence. Along the Y direction on the discharging side of the single punching machine, a vision detection device, a robotic arm, an oiling mechanism, and a continuous die punching machine are arranged in sequence;

The lower die assembly is located above the conveyor 1.

[0014] A lower swing guide assembly and a lower wheel set are installed between the bottom surface of the swing seat and the working platform. The swing seat is driven by a power mechanism to move relative to the working platform in the width direction of the strip.

[0015] Support beams are symmetrically installed at the lower parts of the opposite side surfaces of the main slider. The lower parts of the two support beams are jointly slidably equipped on the opposite sides of the upper die assembly. The upper die assembly is supported by the support beams. Multiple groups of upper wheel sets are installed along the length direction of the support beams. The support beams are supported on the bottom surface of the upper die assembly through the upper wheel sets. The top surface of the upper die assembly and the bottom surface of the main slider are slidably equipped through an upper swing guide assembly.

[0016] The progressive die punching machine includes columns installed at intervals on a support table. An oiling mechanism is installed on the top surface of the support table at the feeding end of the progressive die punching machine. The structure of the oiling mechanism is as follows: It includes a downward driving assembly installed between two columns through a support plate. A sponge block is installed at the lower end of the downward driving assembly. A fuel supply assembly is supported and installed on the support table directly below the sponge block. An oil receiving box is installed in the middle of the support rod below the fuel supply assembly. The fuel supply assembly includes an oiling plate and a transfer plate that are fitted together up and down. An oil storage space is formed between the oiling plate and the transfer plate. The oil storage space is connected to an external fuel supply device through a pipeline. Oil outlet holes are opened on the oiling plate and are connected to the lower oil storage space below.

[0017] Multiple concentric concave oil collecting grooves are formed on the top surface of the oiling plate from the inside to the outside. The top surface of the oiling plate inside and outside each circle of oil collecting grooves is recessed to form oil outlet grooves. Multiple oil outlet holes are arranged at intervals along the length direction at the bottom of the oil outlet grooves. It further includes a falling oil structure connected to each oil collecting groove. The oil in the oil collecting grooves falls into the oil receiving box through the falling oil structure.

[0018] The top surface of the adapter plate is concave to form an oil storage space. An oil inlet hole is opened on the bottom surface of the oil storage space, and the end of the pipeline connected to the external oil supply device is installed at the oil inlet hole. The top surface of the adapter plate inside the inner edge and outside the outer edge of the oil storage space is respectively concave to form an inner sealing groove and an outer sealing groove. Sealing rings are respectively installed in the inner sealing groove and the outer sealing groove, and the sealing rings are press-fitted between the oiling plate and the adapter plate.

[0019] A lifting seat is installed at the lower end of the downward driving assembly. A sponge block is installed on the bottom surface of the lifting seat through a sponge seat. A central hole is opened in the middle of the sponge block, and more than one set of blanking components are installed on the sponge seat at the central hole of the sponge block.

[0020] The structure of a single set of blanking components is as follows: It includes a bushing installed on the sponge seat. A ejector rod is movably installed through the bushing. An end block protrudes outward from the bottom end of the ejector rod. A flexible member is installed on the end face of the end block. An end cover is installed at the top end of the ejector rod extending upward from the bushing. An elastic member is sleeved on the ejector rod between the bushing and the end block.

[0021] A using method of the aluminum cylinder stamping continuous production device described above includes the following steps:

[0022] The coil of the strip is installed on the feeder, and the feeder continuously feeds the strip towards the flattening machine. The strip leveled by the flattening machine is stamped into strip pieces at the single stamping machine.

[0023] After the single stamping machine performs a single stamping, the offset seat drives the lower die assembly and the upper die assembly to move in the Y direction. At the same time, the strip moves in the length direction. By the repeated action of the single stamping machine, it performs another stamping in the inclined direction of the previous stamping on the strip. After that, the offset seat drives the lower die assembly and the upper die assembly to move in the reverse Y direction. Combined with the conveying of the strip, the stamping action is repeated.

[0024] The strip pieces stamped by the single stamping machine fall to the first conveyor, are conveyed to the visual inspection device for inspection, and then are transferred by the robotic arm to the oiling mechanism for double-sided oiling, and then are stamped into aluminum cylinders by the progressive die press.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] The present invention takes a single stamping machine as the layout turning point, realizes the connection layout of the front single stamping die and the rear continuous die, and can directly form an aluminum casing from the feeding of the coil stock through automated continuous production, achieving continuous automated production of aluminum casing stamping. The overall layout is compact and reasonable. Moreover, in the case of omitting the layout of the swing machine, the single stamping machine effectively integrates the swing performance to ensure the high utilization rate of the strip material, especially suitable for use in occasions with limited space. Thus, it effectively reduces the floor area, eliminates the material turnover, greatly helps to reduce costs, and helps to improve the forming efficiency of the aluminum casing and ensure the forming effect.

[0027] The present invention also has the following advantages:

[0028] Integrate the oiling mechanism into the continuous die stamping press. The downward sponge block combines with the oil supply component to achieve double-sided oiling of the strip material, thus replacing manual oiling with automatic oiling, effectively improving the efficiency, and can be connected in series to the automated production line to match the stamping rhythm, and can also effectively ensure the consistency of the double-sided oiling effect.

[0044] The following combines the drawings to illustrate the specific embodiments of the present invention.

[0045] As Figure 1 shown, the aluminum casing stamping continuous production device of this embodiment has an overall L-shaped layout structure, including a single stamping machine 3 located at the corner. Along the X direction on the feeding side of the single stamping machine 3, a flattening machine 2 and a feeding machine 1 are arranged in sequence. Along the Y direction on the discharging side of the single stamping machine 3, a vision inspection device 6, a robot arm 7, an oil coating mechanism 5, and a progressive die press 4 are arranged in sequence.

[0046] In this embodiment, the single stamping machine 3 is used as the layout turning point, realizing the connection layout of the front single stamping die and the rear continuous die. The coiled material can be directly formed into an aluminum casing through automated continuous production from the feeding of the coiled material, achieving continuous automated production of aluminum casing stamping. The overall layout is compact and reasonable.

[0047] As Figure 2 and Figure 3 shown, a main slider 313 is slidably installed up and down above the working platform 311 of the single stamping machine 3 through an outer guide pillar assembly 312. A yaw seat 32 is movably installed along the Y direction on the top surface of the working platform 311. A lower die assembly 34 is installed above the yaw seat 32. A conveyor 8 is arranged along the Y direction between the yaw seat 32 and the lower die assembly 34; a top die assembly 35 is movably equipped along the Y direction on the bottom surface of the main slider 313. The top die assembly 35 and the lower die assembly 34 are equipped with each other through an inner guide pillar assembly 37. A strip 10 is arranged along the X direction between the top die assembly 35 and the lower die assembly 34.

[0048] In this embodiment, by arranging the yaw seat 32 on the working platform 311, the yaw movement of the yaw seat 32 drives the die to yaw left and right. Thus, without arranging a yaw machine, the single stamping machine 3 effectively integrates the yaw performance to ensure the high utilization rate of the strip 10, especially suitable for use in occasions with limited space.

[0049] In this embodiment, through the arrangement of the conveyor 8 between the yaw seat 32 and the lower die assembly 34, the effective automated stringing of the single stamping machine 3 is realized, and the conveyor 8 continuously conveys the sheet 20 stamped by the single stamping machine 3 to the rear process.

[0050] As Figure 4 shown, it further includes a conveyor 61 arranged along the Y direction and passing through the visual inspection device 6. The tail end of the conveyor 8 is connected above the conveyor 61; the visual inspection device 6 includes a camera assembly 62 arranged downward towards the conveyor 61.

[0051] In this embodiment, the layout of the light source and the like can be arranged in cooperation with the camera assembly 62 according to actual needs.

[0052] In this embodiment, the center of each sheet 20 can be identified and determined according to the visual inspection device 6, which is convenient for the subsequent grasping of the robotic arm 7. The appearance defects of the sheet 20 can also be detected through the visual inspection device 6, and the double-sided defect detection of the sheet 20 can also be carried out in combination with the robotic arm 7.

[0053] On the working platform 311 outside both ends of the yaw seat 32, a support 80 is installed. The conveyor 8 is supported and installed on the top surface of the support 80. The yaw seat 32 is located below the conveyor 8. A bellows protective cover 33 is installed between the two end faces of the yaw seat 32 and the corresponding support 80. On the yaw seats 32 on both sides of the conveyor 8, a support seat 341 is installed. The lower die assembly 34 is supported and installed on the top surface of the support seat 341. The lower die assembly 34 is located above the conveyor 8.

[0054] In this embodiment, the lower die assembly 34, the conveyor 8, and the yaw seat 32 are arranged in a stacked manner from top to bottom. The punched sheet 20 can be received and conveyed backward by the conveyor 8 located below the lower die assembly 34. Moreover, the movement of the yaw seat 32 can drive the lower die assembly 34 to yaw. The yaw direction is along the length direction of the conveyor 8, effectively ensuring the high utilization rate of the strip 10, ensuring the smooth progress of stamping, and the overall layout is compact, ingenious, and reasonable.

[0055] In this embodiment, a waste guide 38 is further included. The waste guide 38 is located at the position where the strip 10 passes through the lower die assembly 34, and the waste guide 38 is in a downward inclined structure. The waste guide 38 can be fixed to the working platform 311 via a bracket, effectively ensuring the discharge guide of the strip 10 after stamping.

[0056] A lower yaw guide assembly 325 and a lower wheel set 321 are installed between the bottom surface of the yaw seat 32 and the working platform 311. The yaw seat 32 is driven by a power mechanism to move relative to the working platform 311 in the width direction of the strip 10.

[0057] In this embodiment, the guide rail in the lower yaw guide assembly 325 is fitted into the accommodation groove 3111 on the top surface of the working platform 311. Another accommodation groove 3111 for accommodating the support plate 326 is provided on the top surface of the working platform 311. The slider that is slidably fitted with the guide rail in the lower yaw guide assembly 325 is installed on the bottom surface of the yaw seat 32. The lower wheel set 321 is installed on the bottom surface of the yaw seat 32, and the lower wheel set 321 is rollingly fitted on the support plate 326, so that a rolling contact is formed between the yaw seat 32 and the working platform 311, effectively reducing the friction force during relative movement and ensuring the smoothness of relative movement. Combined with the setting of the lower yaw guide assembly 325, it helps to ensure the smoothness, reliability, and stability of the yaw movement of the yaw seat 32 relative to the working platform 311.

[0058] In this embodiment, through the setting of the accommodation groove 3111, the lower yaw guide assembly 325, the lower wheel set 321, etc. are effectively sunk and accommodated in the working platform 311. The overall structure is compact and reasonable, reducing the height of the yaw seat 32 relative to the working platform 311.

[0059] In this embodiment, the power mechanism is a rotational driving power 322. The output end of the rotational driving power 322 is power-connected to a lead screw nut assembly 323. The nut in the lead screw nut assembly 323 is installed on the bottom surface of the yaw seat 32. It further includes a nut guiding assembly 324. The slider in the nut guiding assembly 324 is installed on the nut to guide the linear movement of the nut. Through the operation of the rotational driving power 322, with the cooperation of the screw pair in the lead screw nut assembly 323, the rotation of the lead screw is converted into the axial movement of the nut along the lead screw. Thus, the nut drives the yaw seat 32 to move axially along the lead screw, realizing the yaw movement relative to the working platform 311.

[0060] The rotational driving power 322 in the power mechanism of this embodiment can be a motor assembly.

[0061] On the lower part of the opposite sides of the main slider 313, support beams 36 are symmetrically installed. The lower parts of the two support beams 36 are jointly and slidably assembled on the opposite sides of the upper die assembly 35. The upper die assembly 35 is supported by the support beams 36. Along the length direction of the support beams 36, multiple groups of upper wheel sets 362 are installed. The support beams 36 are supported on the bottom surface of the upper die assembly 35 through the upper wheel sets 362. The top surface of the upper die assembly 35 and the bottom surface of the main slider 313 are slidably assembled through the upper yaw guiding assembly 351.

[0062] In this embodiment, the main slider 313 provides structural and weight support for the upper die assembly 35 via the support beams 36, effectively ensuring the reliability of stamping by the up-and-down movement of the main slider 313. At the same time, it effectively ensures the stability of the synchronous yaw of the upper die assembly 35 with the lower die assembly 34.

[0063] In this embodiment, the cross-section of the support beam 36 is a U-shaped structure with a lateral opening. The horizontal arm of the support beam 36 is assembled in the assembly groove 3131 on the side surface of the main slider 313. The top surface of the lower horizontal arm of the support beam 36 slidably supports the upper die assembly 35. The reliable installation of the support beam 36 on the main slider 313 can be effectively ensured by the lateral assembly groove 3131 in combination with fasteners such as bolts, thus contributing to ensuring the stamping reliability of the stamping assembly.

[0064] In this embodiment, the support beam 36 contacts and supports the upper die assembly 35 through multiple groups of upper wheel sets 362, realizing the rolling support between the upper die assembly 35 and the support beam 36, and effectively ensuring the smooth movement of the upper die assembly 35 relative to the support beam 36.

[0065] In this embodiment, a long groove 360 is formed along the length direction of the support beam 36. The pin shaft 361 passes through the long groove 360 from the outside to the inside and is then assembled on the side surface of the upper die assembly 35. Through the pin shaft 361 assembled in the long groove 360 of the support beam 36, matching the support between the upper die assembly 35 and the upper wheel sets 362, the gravity of the upper die assembly 35 is transferred and supported on the support beam 36 via the pin shaft 361, effectively ensuring the smooth rolling of the upper wheel sets 362.

[0066] The continuous die punching machine 4 includes columns 41 installed at intervals on a support platform 42, and an oiling mechanism 5 is installed on the top surface of the support platform 42 at the feeding end of the continuous die punching machine 4; Figure 5 and Figure 6 As shown, the structure of the oiling mechanism 5 is as follows: it includes a downward driving assembly 51 installed between two columns 41 via a supporting plate 52, and a sponge block 54 is installed at the lower end of the downward driving assembly 51; an oil supply assembly 55 is installed on the supporting platform 42 directly below the sponge block 54 via a support rod 56, an oil receiving box 57 is installed in the middle of the support rod 56 below the oil supply assembly 55, and a bottom plate 58 is installed at the bottom end of the support rod 56, and the bottom plate 58 is fixed on the supporting platform 42; the oil supply assembly 55 includes an oiling plate 551 and an adapter plate 553 which are fitted together upper and lower, and an oil storage space 5531 is formed between the oiling plate 551 and the adapter plate 553, and the oil storage space 5531 is connected to an external oil supply device via a pipeline, and an oil outlet hole 5514 connected to the oil storage space 5531 below is opened on the oiling plate 551.

[0067] In this embodiment, the oiling mechanism 5 is integrated into the continuous die punch 4, and the downward sponge block 54 is combined with the oil supply component 55 to achieve double-sided oiling of the sheet 20, so that automatic oiling replaces manual oiling, which effectively improves efficiency, can be connected in series to the automated production line to match the stamping rhythm, and can also effectively ensure the consistency of the double-sided oiling effect.

[0068] In this embodiment, before the oiling mechanism 5 applies oil to the sheet 20, the downward driving component 51 first drives the sponge block 54 downward, and the sponge block 54 is in contact with the top surface of the oiling plate 551 of the oil supply component 55, so that the bottom surface of the sponge block 54 absorbs oil, and then the downward driving component 51 drives the sponge block 54 upward to a preset height; then the robot arm 7 places the sheet 20 on the oil supply component 55, and combines it with the sponge block 54 to apply oil on both sides.

[0069] like Figure 8 As shown, the top surface of the oiling plate 551 is provided with a plurality of circles of concave oil collecting grooves 5512 from the inside to the outside, and the top surfaces of the oiling plate 551 located on the inner and outer sides of each circle of oil collecting grooves 5512 are concave to form oil outlet grooves 5511, and the bottom of the oil outlet grooves 5511 is provided with a plurality of oil outlet holes 5514 spaced apart along the length direction; an oil drop structure connected to each oil collecting groove 5512 is also included, and the oil in the oil collecting groove 5512 drops to the oil receiving box 57 through the oil drop structure.

[0070] In this embodiment, the oil in the oil storage space 5531 flows through the oil outlet hole 5514 to the oil outlet groove 5511 on the top surface of the oiling plate 551. The excess oil in the oil outlet groove 5511 will smoothly flow through the oil collecting groove 5512 to the falling oil structure and fall. Moreover, the depth of the oil collecting groove 5512 is greater than that of the oil outlet groove 5511, thereby effectively ensuring the rapid and smooth collection of the excess oil and guaranteeing the uniformity and consistency of the oiling on the bottom surface of the workpiece 20 placed on the oiling plate 551.

[0071] In this embodiment, guide blocks 552 are circumferentially and spacedly installed on the top surface of the oiling plate 551 outside the outermost oil outlet groove 5511. The inner side surface of the guide block 552 is an inclined surface that slopes downward and inward, which can realize the rapid placement and positioning of the workpiece 20 on the oil supply assembly 55 and can circumferentially limit the workpiece 20 during oiling.

[0072] In this embodiment, a concave structure 5517 is formed by the downward depression of the top surface of the oiling plate 551 inside the innermost oil outlet groove 5511. A through hole 5515 is opened at the center of the concave structure 5517, and a through hole 5534 is opened on the transfer plate 553 opposite to the through hole 5515; a notch 5513 is inwardly opened on the opposite edge of the oiling plate 551, and a notch 5533 is opened on the transfer plate 553 opposite to the notch 5513; the oil collecting groove 5512 is communicated with the notch 5513 or the concave structure 5517, so that the falling oil structures are respectively formed inside and outside the oiling plate 551 by the concave structure 5517 and the notch 5513, and are communicated with the adjacent oil collecting groove 5512. The overall structure is simplified, which helps to ensure the smooth falling of the oil in the oil collecting groove 5512.

[0073] Both ends of the oil collecting groove 5512 are respectively communicated with the notch 5513, or the oil collecting groove 5512 is communicated with the notch 5513 or the concave structure 5517 through a radial through groove 5516, effectively ensuring the rapid and smooth falling of the oil in the oil collecting groove 5512.

[0074] The top surface of the transfer plate 553 is downwardly depressed to form an oil storage space 5531. An oil inlet hole 5536 is opened at the bottom surface of the oil storage space 5531, and the end of the pipeline connected to the external oil supply device is installed at the oil inlet hole 5536. The external oil supply device supplies oil into the oil storage space 5531 through the oil inlet hole 5536; the top surface of the transfer plate 553 inside the inner edge and outside the outer edge of the oil storage space 5531 is respectively downwardly depressed to form an inner sealing groove 5535 and an outer sealing groove 5532, as Figure 7As shown in the figure; sealing rings are respectively installed in the inner sealing groove 5535 and the outer sealing groove 5532. The sealing rings are press-fitted between the oiling plate 551 and the adapter plate 553, so as to realize the circumferential sealing of the edge of the oil storage space 5531 between the oiling plate 551 and the adapter plate 553, effectively preventing or even avoiding the leakage of oil liquid at the joint surface of the oiling plate 551 and the adapter plate 553, and effectively ensuring that the oil storage space 5531 supplies oil to the top surface of the oiling plate 551 through the oil outlet hole 5514.

[0075] A lifting seat 53 is installed at the lower end of the downward driving assembly 51. A sponge block 54 is installed on the bottom surface of the lifting seat 53 through a sponge seat 541; a central hole is formed in the middle of the sponge block 54, and more than one set of stripping components 59 are installed on the sponge seat 541 at the central hole of the sponge block 54, such as Figure 9 shown in the figure.

[0076] In this embodiment, a stripping component 59 is arranged inside the sponge block 54. After the sponge block 54 is driven downward by the downward driving assembly 51 to apply oil to the top surface of the workpiece 20, the stripping component 59 will apply force to the top surface of the workpiece 20 to promote the smooth separation of the top surface of the workpiece 20 from the sponge block 54, effectively ensuring the continuous operation of automatic oiling; a reinforcing plate 590 is fitted and attached to the bottom surface of the sponge seat 541 at the center of the sponge block 54, and the reinforcing plate 590 can be locked to the lifting seat 53 above the sponge seat 541 through bolts.

[0077] In this embodiment, the downward driving assembly 51 is a pen-shaped cylinder installed on the support plate 52 with the output end facing downward. A connecting plate is installed at the upper end of the pen-shaped cylinder. Guide rods 511 are movably installed through the support plate 52 on both sides of the pen-shaped cylinder up and down. The top end and the bottom end of the guide rods 511 are respectively installed on the connecting plate and the lifting seat 53.

[0078] As Figure 10 shown in the figure, the structure of a single set of stripping component 59 is: including a bushing 594 installed on the sponge seat 541, a ejector rod 592 is movably installed through the bushing 594. An end block extends outwardly from the bottom end of the ejector rod 592, and a flexible member 591 is installed on the end face of the end block. An end cover 595 is installed at the top end of the ejector rod 592 extending upward out of the bushing 594; an elastic member 593 is sleeved on the ejector rod 592 between the bushing 594 and the end block.

[0079] In this embodiment, during use, as the sponge block 54 moves downward and presses against the top surface of the workpiece 20, the bottom surface of the flexible member 591 abuts against the top surface of the workpiece 20, and the ejector rod 592 is forced to move upward relative to the bushing 594 and the sponge seat 541, and the elastic member 593 is compressed; when the sponge block 54 moves upward and is about to separate from the workpiece 20, the compressed elastic member 593 drives the ejector rod 592 to move downward and reset, so as to apply a downward force to the workpiece 20 through the flexible member 591, making the workpiece 20 smoothly separate from the sponge block 54.

[0080] In this embodiment, the upper die assembly 35 and the lower die assembly 34 of the single stamping machine 3 can adopt the existing conventional stamping die structure. With the operation of the press, as the main slider 313 moves downward, the upper die assembly 35 and the lower die assembly 34 are closed to stamp the strip 10. The single stamping machine 3 in this embodiment can use a hydraulic press as the stamping power.

[0081] In this embodiment, the progressive die of the progressive die press 4 can adopt the existing conventional progressive die structure. With the operation of the press, continuous stamping and forming of the blank 20 are realized. The progressive die press 4 in this embodiment can use a hydraulic press as the progressive die stamping power.

[0082] The usage method of the aluminum casing stamping continuous production device in this embodiment includes the following steps:

[0083] Step 1: The coil of the strip 10 is assembled on the feeder 1, and the feeder 1 continuously feeds the strip 10 towards the flattening machine 2. The strip 10 leveled by the flattening machine 2 is stamped into the blank 20 at the single stamping machine 3.

[0084] Step 2: After the single stamping machine 3 performs a single stamping, the swing seat 32 drives the lower die assembly 34 and the upper die assembly 35 to move in the Y direction. At the same time, the strip 10 moves in the length direction. By the repeated action of the single stamping machine 3, stamping is performed again in the inclined direction of the previous stamping on the strip 10. After that, the swing seat 32 drives the lower die assembly 34 and the upper die assembly 35 to move reversely in the Y direction, and in combination with the conveying of the strip 10, the stamping action is repeated. Specifically:

[0085] The power mechanism works to drive the swing seat 32 to move relative to the working platform 311 along the width direction of the strip 10. The strip 10 moves or does not move in the length direction according to the actual stamping requirements. In this embodiment, the stamped part is a circular blank 20. While the swing seat 32 swings and moves, the strip 10 moves about the radius length of the circular blank 20 in the length direction. The swing seat 32 drives the lower die assembly 34 and the upper die assembly 35 to swing and move synchronously relative to the working platform 311 and the main slider 313. Then the press works, and the main slider 313 drives the upper die assembly 35 to close towards the lower die assembly 34 again to stamp the strip 10. After stamping is completed, the swing seat 32 moves reversely relative to the working platform 311, and the above stamping action is repeated.

[0086] Step 3: The blank 20 stamped by the single stamping machine 3 falls to the conveyor 8, is conveyed to the visual inspection device 6 for inspection, and then is transferred to the oiling mechanism 5 by the robotic arm 7 for double-sided oiling, and then is stamped into an aluminum casing by the progressive die press 4.

[0087] The present invention realizes the continuous automated production of aluminum casing stamping, eliminates the layout of the yaw machine, effectively integrates the yaw performance to ensure the high utilization rate of the strip, thereby effectively reducing the floor area, eliminating the material turnover, greatly contributing to cost reduction, and contributing to improving the forming efficiency of the aluminum casing and ensuring the forming effect.

[0088] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same and similar parts among the various embodiments, reference may be made to each other.

[0089] The above description is an explanation of the present invention, not a limitation of the invention. For the scope defined by the present invention, refer to the claims. Any form of modification may be made within the protection scope of the present invention.
