Description

Technical Field

[0001] This application relates to the field of aerosol can processing technology, and in particular to a multi-specification aerosol can cap stamping and feeding device. Background Technology

[0002] Stamping is a processing method that uses a press and dies to apply external force to metal sheets, strips, tubes, and profiles, causing them to undergo plastic deformation or separation, thereby obtaining workpieces of specific shapes and sizes (stamped parts). Stamping and forging both belong to the category of plastic processing (or pressure processing), collectively known as forging and pressing. The blanks for stamping mainly use hot-rolled and cold-rolled steel sheets and strips. Globally, approximately 60-70% of steel production is in sheet metal, most of which is processed into finished products through stamping. Automobile bodies, chassis, fuel tanks, radiator fins, boiler drums, container shells, and silicon steel sheets for motor and electrical appliance cores are all produced using stamping processes. In addition, stamped parts are widely used in instruments, household appliances, bicycles, office machinery, and household utensils. However, some current equipment, in order to reduce production costs, has overly simple functional designs, requiring manual assistance to remove parts after stamping; at the same time, the equipment lacks a buffer structure, making it prone to workpiece breakage due to over-stamping.

[0003] To address the aforementioned problems, a processing device has emerged. For example, Chinese invention patent CN116748408B discloses a continuous stamping and feeding device for aerosol can cap processing. Specifically, it includes: a fixed platform with evenly spaced rotating grooves at its bottom; a support column fixedly connected to the center of the bottom of the fixed platform; a fixing mechanism rotatably connected to the top of the fixed platform; an annular groove on the outer surface of the support column; a rotating shaft rotatably connected to the outer surface of the annular groove; a steering rod rotatably connected to the outer surface of the rotating shaft; a connecting frame rotatably connected to the outer surface of the steering rod; and a strip plate fixedly connected to the top of the connecting frame. This invention relates to the field of stamping technology. This continuous stamping and feeding device for aerosol can cap processing includes a fixing mechanism, a pressurizing mechanism, and an ejection mechanism internally. An auxiliary structure with a cover is also included inside the device to provide relief during the stamping process. A curved receiving plate is added at the discharge position to prevent the processed material from leaving the device during rotation, improving heat dissipation and facilitating the collection of workpieces. Since the aerosol can cap is made of thin metal sheet, the above-mentioned equipment is prone to circumferential / radial displacement in the positioning groove due to pressure impact during stamping, resulting in dimensional deviation of the can cap stamping, edge warping, and low finished product qualification rate; and the anti-slip ring is a fixed structure, which cannot be adapted to the processing of aerosol can caps of different diameters. Therefore, a multi-specification aerosol can cap stamping and feeding device is proposed to solve the above problems. Summary of the Invention

[0004] The purpose of this application is to propose a multi-specification aerosol can cap stamping and feeding device to solve the problem of difficult part removal in traditional equipment. After the top cap is formed, the rolled edge section is tightly fitted with the annular notch of the die due to elastic recovery. Moreover, the die cavity is a closed forming space and lacks an active ejection mechanism. Manual part removal is not only inefficient, but also easily leads to deformation and damage of the rolled edge section, which directly affects the product qualification rate.

[0005] To achieve this objective, the following technical solution is adopted in this application: A multi-specification aerosol can cap stamping and feeding device includes a workbench and a top plate. The top plate is connected above the workbench via two sets of connecting components. A support column is located at the center of the bottom end of the workbench.

[0007] According to the claim 1, a multi-specification aerosol can cap stamping and feeding device is characterized in that the end of the positioning block away from the spring is provided with a rounded chamfer.

[0008] According to the claim 1, a multi-specification aerosol can cap stamping and feeding device is characterized in that, in its natural state, the positioning block extends out of the first through hole by -mm.

[0009] According to the claim, a multi-specification aerosol can cap stamping and feeding device is characterized in that the pressurizing mechanism includes a rotary table, a connecting mold, a vertical shaft, and a steering ring. The rotary table is rotatably connected in the circular groove, the connecting mold is fixed at the bottom end of the rotary table, the vertical shaft is rotatably connected at the bottom end of the connecting mold, the outer surface of the vertical shaft is fixed with a steering ring, and the bottom end of the steering ring is provided with multiple suction cups at equal intervals along the circumference.

[0010] According to the claim 1, a multi-specification aerosol can cap stamping and feeding device is characterized in that the pressurizing mechanism includes a bent rod and a pressing ball, the bent rod is rotatably connected to the edge of the top plate, a plurality of triangular grooves are equidistantly provided on the bent rod along its length direction, the pressing ball is fixed to the end of the bent rod, and the pressing ball is in contact with the top of the rotating table.

[0011] According to the claim 1, a multi-specification aerosol can cap stamping and feeding device is characterized in that the ejection mechanism includes an extrusion rod, two rotating balls, two rubber rods, and two abutment plates. The extrusion rod is vertically arranged at the bottom end of the top plate, and the two rotating balls are both arranged on the extrusion rod. One end of the rubber rod is fixedly connected to the corresponding rotating ball, and the other end of the rubber rod is fixedly connected to the corresponding abutment plate.

[0012] According to the claim 1, a multi-specification aerosol can cap stamping and feeding device is characterized in that the fixing mechanism includes a drive rod, the worktable is provided with rotating grooves at equal intervals along the circumference, the drive rod is rotatably connected in the rotating grooves, and the drive rod is slidably connected to the bottom end of the curved disk.

[0013] According to the claim 1, a multi-specification aerosol can cap stamping and feeding device is characterized in that it further includes a receiving pipe, the receiving pipe is located at the bottom end of the workbench, the curved plate is provided with a plurality of curved grooves for workpieces to pass through, and the opening of the receiving pipe is located below the curved grooves.

[0014] According to the claim 1, a multi-specification aerosol can cap stamping and feeding device is characterized in that the connecting assembly includes a connecting plate, a sliding rod, a connecting frame, and a steering rod, one end of the steering rod is hinged to the support column, the other end of the steering rod is hinged to the connecting frame, the connecting frame has a through hole, the sliding rod is slidably disposed in the through hole, both ends of the sliding rod are rotatably connected to two connecting plates respectively, and the ends of the two connecting plates away from the sliding rod are both hinged to the top plate.

[0015] Compared to existing technologies, the beneficial effects of this application are: 1. Place the materials needed to make aerosol can caps on the ejector mechanism and in multiple storage holes. Drive the lifting platform upward and rotate it through the screw lifter. As the lifting platform slowly rises, it works with the pressurizing mechanism to press downward into the storage holes. The adjustable anti-deviation component allows aerosol can caps of different specifications to be placed in the storage holes for processing and prevents the aerosol cans from radially shifting within the storage holes.

[0016] 2. The spring and positioning block work together to flexibly clamp the can lid plate, offsetting the impact force during stamping and preventing radial displacement. Rotating the knob can drive the adjusting screw. Since the adjusting screw extends into the threaded hole and is threadedly connected to the threaded hole, the rotation of the adjusting screw can drive the mounting plate, spring, and positioning block to move, thereby adjusting the distance of the positioning block extending out of the first through hole, so as to adapt to aerosol cans of different diameters and improve the versatility of the equipment.

[0017] 3. The external drive mechanism drives the pressing ball to move downward and contact the upper end of the rotary table, forming a force that drives the connecting mold below to align with the placement hole and press downward. Before the pressing, the upper vertical shaft rotates, driving the steering ring to cover the top of the placement hole, limiting the impact force of the pressing structure and reducing damage.

[0018] 4. After stamping, the material rotates to the underside of the extrusion rod. After the extrusion rod enters, it pushes the material downward to complete demolding. During demolding, the abutments on both sides will form a supporting force with the outer side of the placement hole to prevent the material from sticking to the mold. After the pressed material falls to the outside of the curved disk, the rotation of the curved disk and the gap of the curved groove accelerate the contact between the material and the air, which has a rapid heat dissipation effect.

[0026] Example 1: Figure 1 This application provides a multi-specification aerosol can cap stamping and feeding device, including a workbench 1 and a top plate 2. The top plate 2 is connected above the workbench 1 by two sets of connecting components. A support column 3 is provided at the center of the bottom end of the workbench 1. A fixing mechanism is provided on the workbench 1. It also includes a pressurizing mechanism, an ejection mechanism, a curved disk 4, a screw jack, and a lifting platform 5. A circular groove is opened on the top plate 2. The pressurizing mechanism is located in the circular groove. The ejection mechanism is located at the bottom end of the top plate 2. The curved disk 4 is rotatably connected above the workbench 1. A first through hole is opened in the center of the curved disk 4. The screw jack is provided on the support column 3. The lifting end of the screw jack passes through the first through hole and is connected and fixed to the lifting platform 5. The lifting platform 5 is located above the curved disk 4. Multiple placement holes 6 are opened on the lifting platform 5. Adjustable anti-deviation components are provided at the placement holes 6 to adapt to different aerosol cans placed in the placement holes 6 for processing.

[0027] In this embodiment, the materials to be made into aerosol can caps are placed on the ejection mechanism and in multiple storage holes 6. The lifting platform 5 is driven to move upward and rotate by the screw lifter. During the slow ascent, the lifting platform 5, in conjunction with the pressurization mechanism, is aligned with the storage holes 6 and pressed downward. The adjustable anti-deviation component allows aerosol can caps of different specifications to be placed in the storage holes 6 for processing, and prevents the aerosol cans from radially shifting within the storage holes 6.

[0028] Example 2: Preferably, as another embodiment of this application, such as Figure 2 and Figure 3 As shown, the adjustable anti-deviation assembly includes a positioning block 71, a spring 72, a mounting plate 73, an adjusting screw 74, and a knob 75. The placement hole 6 has a first through hole adapted to the positioning block 71, and the positioning block 71 is slidably disposed in the first through hole. The lifting platform 5 has a threaded hole and a second through hole, which are respectively connected to the first through hole and the threaded hole. The mounting plate 73 is slidably disposed in the second through hole. The adjusting screw 74 extends into the threaded hole and is threadedly connected to the threaded hole. One end of the adjusting screw 74 is coaxially and fixedly connected to the knob 75, and the other end of the adjusting screw 74 is fixedly connected to the mounting plate 73. One end of the spring 72 is connected to the mounting plate 73, and the other end of the spring 72 is connected to the positioning block 71.

[0029] In this embodiment, as one implementation method, the spring 72 and the positioning block 71 work together to flexibly clamp the can lid plate, offset the impact force during stamping, and prevent radial displacement. Rotating the knob 75 can drive the adjusting screw 74. Since the adjusting screw 74 extends into the threaded hole and is threadedly connected to the threaded hole, the rotation of the adjusting screw 74 can drive the mounting plate 73, spring 72, and positioning block 71 to move, thereby adjusting the distance of the positioning block 71 extending out of the first through hole, so as to adapt to aerosol cans of different diameters and improve the versatility of the equipment.

[0030] Preferably, the end of the positioning block 71 away from the spring 72 has a rounded chamfer. This makes it less likely for the positioning block 71 to interfere with the placement of the aerosol can lid.

[0031] In the natural state of the spring 72, the positioning block 71 extends 2-3mm out of the first through hole.

[0032] Example 3: Preferably, as another embodiment of this application, the pressurizing mechanism includes a rotary table 81, a connecting mold 82, a vertical shaft 83, and a steering ring 84. The rotary table 81 is rotatably connected in a circular groove, the connecting mold 82 is fixed to the bottom end of the rotary table 81, the vertical shaft 83 is rotatably connected to the bottom end of the connecting mold 82, and the steering ring 84 is fixed on the outer surface of the vertical shaft 83. Multiple suction cups 85 are equidistantly arranged along the circumferential direction at the bottom end of the steering ring 84. More specifically, the pressurizing mechanism includes a bent rod 91 and a pressing ball 92. The bent rod 91 is rotatably connected to the edge of the top plate 2, and multiple triangular grooves 93 are equidistantly arranged on the bent rod 91 along its length direction. The pressing ball 92 is fixed to the end of the bent rod 91 and contacts the top end of the rotary table 81.

[0033] In this embodiment, as one implementation method, an external driving mechanism drives the pressing ball 92 downward to contact the upper end of the rotary table 81, generating a force that drives the connecting mold 82 below to align with the placement hole 6 and press downward. Before pressing, the upper vertical shaft 83 rotates, causing the steering ring 84 to cover the placement hole 6, limiting the impact force of the stamping structure and reducing damage. A rotatable protective structure is provided below the stamped part to alleviate the problem of excessive stamping pressure.

[0034] Example 4: Preferably, as another embodiment of this application, the ejection mechanism includes an extrusion rod 101, two rotating balls 102, two rubber rods 103, and two abutment plates 104. The extrusion rod 101 is vertically arranged at the bottom end of the top plate 2. The two rotating balls 102 are both arranged on the extrusion rod 101. One end of the rubber rod 103 is fixedly connected to the corresponding rotating ball 102, and the other end of the rubber rod 103 is fixedly connected to the corresponding abutment plate 104.

[0035] In this embodiment, as one implementation method, the material after stamping rotates to the area directly below the extrusion rod 101. After the extrusion rod 101 enters, it pushes the material downward to complete demolding. During demolding, the abutments 104 on both sides will form a supporting force with the outer side of the placement hole 6 to prevent the material from sticking to the mold. After the pressed material falls to the outside of the curved disk 401, the rotation of the curved disk 401 and the gap of the curved groove 403 accelerate the contact between the material and the air, which has a rapid heat dissipation effect.

[0036] Example 5: Preferably, as another embodiment of this application, the fixing mechanism includes a drive rod 11, and the worktable 1 is provided with rotating grooves at equal intervals along the circumference. The drive rod 11 is rotatably connected in the rotating grooves, and the drive rod 11 is slidably connected to the bottom end of the curved disk 4.

[0037] In this embodiment, as one implementation method, the workpiece is prevented from rotating and detaching from the equipment, while the heat dissipation rate of the workpiece is accelerated.

[0038] Preferably, it also includes a receiving pipe 121, which is located at the bottom of the workbench 1. The curved disk 4 has multiple curved grooves 122 for workpieces to pass through, and the opening of the receiving pipe 121 is located below the curved grooves 122.

[0039] The workpieces gradually accumulate on the curved disk 4. When the workpieces roll out from the curved groove 122, they will directly enter the inside of the receiving pipe 121 for unified collection.

[0040] Specifically, the connecting assembly includes a connecting plate 131, a sliding rod, a connecting frame 132, and a steering rod 133. One end of the steering rod 133 is hinged to the support column 3, and the other end of the steering rod 133 is hinged to the connecting frame 132. The connecting frame 132 has a through hole, and the sliding rod is slidably disposed in the through hole. Both ends of the sliding rod are rotatably connected to two connecting plates 131, and the ends of the two connecting plates 131 away from the sliding rod are hinged to the top plate 2.

[0041] The sliding rod slides within the through hole, making the top plate 2 more stable when moving up and down above the worktable 1.

[0042] How this application works: The material to be used to make aerosol can caps is placed on the extrusion rod 101 and into multiple storage holes 6. A screw jack drives the lifting platform 5 upwards and rotates. As the lifting platform 5 slowly rises, an external drive mechanism moves the pressure ball 92 downwards, contacting the upper end of the rotating platform 81 and generating force. This force drives the connecting mold 82 below to align with the storage holes 6 and press downwards. Before pressing, the upper vertical shaft 83 rotates, causing the steering ring 84 to cover the storage holes 6, limiting the impact force of the pressing structure and reducing damage. After pressing, the material... The material rotates to the area directly below the extrusion rod 101. After the extrusion rod 101 enters, it pushes the material downwards to complete demolding. During demolding, the abutments 104 on both sides will form a supporting force with the outer side of the placement hole 6 to prevent the material from sticking to the mold. After the pressed material falls to the outside of the curved disk 401, the rotation of the curved disk 401 and the gap of the curved groove 403 accelerate the contact between the material and the air, which has a rapid heat dissipation effect. The workpieces gradually accumulate on the curved disk 4. When the workpieces roll out from the curved groove 122, they will directly enter the inside of the receiving pipe 121 for unified collection.
