Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically to a rapid edge-rolling mechanism. Background Technology

[0002] After metal drums and lids are stamped, their edges need to be rolled into rounded edges. Rounded edges greatly increase the strength of the lid and prevent scratches to users. Existing rolling methods cause significant wear on the rolling wheels and generate considerable stress on the drum body, potentially leading to deformation or cracks. As the metal drum rotates at high speed on the rolling machine, the rolling wheels force the drum to be rolled, generating high-speed friction and high temperatures. Lubrication of the rolling wheels is essential to improve sealing quality, stabilize product quality, and extend the wheel's lifespan. However, the application of lubricating oil to the rolled edge during sealing can cause subsequent processes, coating processes, and insufficient paint adhesion at the sealed edge. This necessitates additional degreasing treatment at the sealed area, which is inconvenient. Furthermore, existing rolling equipment has a complex structure and poor rolling stability, affecting product quality.

[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses an insert injection mold [CN202310821834.8], which includes a worktable, a frame, a linear actuator, a bottom support, and a top fixed platform. The frame is mounted on the upper wall of the worktable, the linear actuator is mounted on the side wall of the frame, the bottom support is mounted on the linear actuator, a top bracket is provided at the upper end of the frame, the top fixed platform is located below the top bracket, a curling wheel is rotatably provided at the bottom end of the top fixed platform, an inner support mechanism is provided at the center of the bottom wall of the top fixed platform, a clamping mechanism is provided on the upper wall of the bottom support, the clamping mechanism and the inner support mechanism are coaxially arranged facing each other, an outer clamping mechanism is provided in the middle of the frame, and an oil stain cleaning mechanism is provided on one side of the top fixed platform.

[0004] The above solution has solved to some extent the problem of high wear on the curling wheel and easy cracking of products caused by the existing curling equipment. However, the solution still has many shortcomings, such as complex structure, poor curling stability, and impact on product quality. Summary of the Invention

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-3 As shown, a rapid hemming mechanism includes a hemming assembly seat 1, a lifting cavity 11 is provided on the inner side of the hemming assembly seat 1, a lifting drive assembly 2 for lifting and supporting the workpiece is provided in the lifting cavity 11, an elastic hemming positioning structure 3 for clamping the workpiece is provided on the upper end surface of the hemming assembly seat 1, and a lifting-type pressing forming structure 4 is provided on the upper end of the elastic hemming positioning structure 3.

[0023] Among them, the bottom of the rolled edge assembly seat 1 is provided with a motor assembly hole 12, and the inner wall of the lifting cavity 11 is provided with a lifting slide rail 13.

[0024] Furthermore, the lifting drive assembly 2 includes a lifting drive motor 21, which is disposed in the motor mounting hole 12. The output end of the lifting drive motor 21 is provided with a flexible lifting cylinder 22, and the workpiece to be rolled is disposed on the upper end face of the flexible lifting cylinder 22.

[0025] The lifting drive motor 21 drives the flexible lifting cylinder 22 to rise, and the flexible lifting cylinder 22 lifts the workpiece positioned on the upper end face to the set position, where the edge-rolling positioning seat 31 will press it.

[0026] Furthermore, the upper end face of the flexible lifting cylinder 22 has a workpiece positioning part 221 and the lower end is provided with a lifting sliding part 222. The outer circumferential wall of the lifting sliding part 222 is provided with a guide slot 223, and the flexible lifting cylinder 22 and the inner wall of the lifting cavity 11 are slidably connected by the lifting slide rail 13 and the guide slot 223.

[0027] The use of lifting slide rail 13 and guide slot 223 enables the flexible lifting cylinder 22 to maintain vertical lifting and lowering, thereby improving positioning accuracy.

[0028] Specifically, the upper end face of the rolled edge assembly base 1 is provided with a clearance through hole 14, the clearance through hole 14 is provided with a positioning groove 15 around its circumference, the positioning groove 15 is provided with a positioning disc body 16, and the elastic rolled edge positioning structure 3 is provided on the upper end face of the positioning disc body 16.

[0029] More specifically, the elastic hemming positioning structure 3 includes several hemming positioning seats 31 connected end to end in pairs. The inner wall of the hemming positioning seat 31 is provided with a hemming positioning groove 32, and the upper end of the hemming positioning seat 31 is an upper pressing part 33 and the lower end is a lower pressing part 34 on the outer side of the periphery.

[0030] The lower clamping part 34 is inclined towards the outer wall.

[0031] The edge curling positioning groove 32 is used to position and curl the edge of the workpiece, and when the workpiece reaches the specified height, the lifting and pressing forming structure 4 is pressed down by the return spring, so that the edge curling positioning seat 31 is squeezed toward the edge of the workpiece to achieve edge curling.

[0032] In detail, the upper surface of the hemmed assembly seat 1 is provided with several spring connecting blocks 35, and the spring connecting blocks 35 are connected to the corresponding hemmed positioning seats 31 through reset springs.

[0033] The return spring is not shown in the figure. When the bottom clamping ring 41 is pressed down, the return spring is subjected to clamping force and loses its restoring force on the rolled edge positioning seat 31.

[0034] More specifically, the lifting and pressing forming structure 4 includes an externally mounted lifting and pressing motor, and the output end of the lifting and pressing motor is sequentially provided with an upper pressing block 42, a middle pressing seat 43, and a bottom pressing ring 41.

[0035] The lifting and pressing motor is not shown in the figure. The upper pressing block 42 is used to press the upper surface of the workpiece to prevent deformation during edge rolling. The middle pressing seat 43 and the bottom pressing ring 41 are used to squeeze the edge rolling positioning seat 31 to promote the forming of the workpiece edge.

[0036] Preferred, the upper pressing block 42 covers the upper end face of the rolled edge positioning seat 31, the middle pressing seat 43 is sleeved on the outer circumferential wall of the upper pressing seat of the rolled edge positioning seat 31, and the bottom pressing ring 41 is sleeved on the outer circumferential wall of the lower pressing part 34.

[0037] The inner wall of the bottom clamping ring 41 has an inclined surface arranged in a ring shape, which fits tightly against the outer wall of the lower clamping part 34.

[0038] In addition, the upper pressure block 42, the middle pressure seat 43, and the bottom pressure ring 41 are interconnected on their circumferential outer walls.

[0039] The gap between the pressure block 42, the middle pressure seat 43 and the bottom pressure ring 41 can be adjusted as needed.

[0040] In summary, the principle of this embodiment is as follows: the flexible lifting cylinder 22 is driven to rise by the drive motor 21, and the flexible lifting cylinder 22 lifts the workpiece positioned on the upper end face to the set position. The edge-rolling positioning seat 31 performs circumferential pressing. At this time, the lifting and pressing motor drives the upper pressing block 42, the middle pressing seat 43 and the bottom pressing ring 41 to press down, and the edge-rolling positioning seat 31 applies an edge-rolling force to the workpiece. The workpiece is formed by force in the edge-rolling positioning groove 32, and the edge-rolling is completed.
