[0022] The following is combined with Figures 1 to 4 Embodiments of the present invention will be described.

[0023] This embodiment relates to a semi-finished product edge-rolling device, used to roll the edges of parts, especially cylindrical parts, while reducing damage to the parts.

[0024] The semi-finished product edge-rolling device of this embodiment includes: Base, edge-rolling mechanism, and feeding mechanism; The hemming mechanism includes a rotary driver 11, a hemming head 12, a lifting seat 13, a lifting driver 16, a positioning platform 14, and a buffer structure. The rotary driver 11 is mounted on the base and is drivenly connected to the hemming head 12. The lifting driver 16 is mounted on the base and is drivenly connected to the lifting seat 13. The positioning platform 14 is mounted on the lifting seat 13. The buffer structure is connected to the lifting seat 13 and provides cushioning when the lifting seat 13 rises and falls. The feeding mechanism includes a feeding chute (not shown in the figure), a pusher driver 22 and a pusher head 23. The feeding chute is located on the base, and the pusher driver 22 is located on the base. The pusher driver 22 is driven to move the pusher head 23 toward the positioning table 14.

[0025] This semi-finished product crimping device achieves automatic feeding of cylindrical parts through a feeding mechanism, and folds the upright surface 71 of the cylindrical parts inward through the crimping mechanism. At the same time, the crimping mechanism is equipped with a buffer structure, which buffers the lifting drive 16, the lifting seat 13 and the positioning table 14, thereby reducing the probability of product damage.

[0026] In this embodiment, the crimping head 12 includes a downwardly extending claw disc and ball bearings 122. The claw disc is connected to the drive end of the rotary driver 11. There are multiple ball bearings 122, which are evenly distributed circumferentially on the inner side of the claw disc. After the material is placed on the positioning table 14, when the material is raised to the height of the ball bearings 122 by the lifting driver 16, the ball bearings 122, which are evenly distributed circumferentially on the inner side of the claw disc, can push the edge of the object, thereby completing the crimping action. Specifically, in this embodiment, when the material is a cylindrical part, the arc-shaped part at the lower end of the ball bearing 122 on the inner side pushes the raised edge of the cylindrical part, bending the raised surface 71 inward. Because the crimping head 12 in this embodiment is equipped with multiple spaced-apart ball bearings 122, the pressing force exerted by the crimping head 12 on the upright surface 71 of the material is relatively small when it comes into contact with the upright surface 71. This reduces the likelihood of wrinkling or tearing on the upright surface 71, thus improving the structural strength of the upright surface 71 after crimping and enhancing the quality of the crimp. The lifting driver 16 can be a pneumatic push rod, an electric push rod, a hydraulic push rod, a linear module, a linear module, a lead screw mechanism, etc., and its main function is to provide an output end for linear motion. In this embodiment, the lifting driver 16 is an electric push rod. Electric push rods have a faster operating speed, and using an electric push rod in the lifting driver 16 can improve operating efficiency and adapt to fast-paced production.

[0027] Furthermore, the claw plate also includes an upper movable seat 121, a lower movable seat 123, and a compression spring 125. The upper movable seat 121 is driven by the lifting driver 16, and the lower movable seat 123 slides up and down along the upper movable seat 121. An upper pad is provided on the outer side of the upper movable seat 121, and a lower pad is provided on the inner side of the lower movable seat 123. The compression spring 125 is located between the upper and lower pads, so that the upper movable seat 121 applies downward pressure to the lower movable seat 123 through the compression spring 125. The aforementioned ball bearing 122 is mounted on the lower movable seat 123. A height limiting block is also provided on the lower side of the lower movable seat 123. An arc-shaped protrusion 124 for secondary bending is also provided on the bottom side of the upper movable seat 121, and the arc-shaped protrusion 124 extends outward. When the lifting drive 16 drives the positioning platform 14 to rise, it first contacts the ball bearing 122 of the lower movable seat 123, bending the upright surface 71 into a horizontal state to form a horizontal fold section 72, until the height limit block contacts the lifting seat 13. At this point, as the positioning platform 14 and the lifting seat 13 continue to rise to the arc-shaped protrusion 124, the arc-shaped protrusion 124 bends the horizontally positioned upright surface 71 downward to form a downward fold section 73, further achieving the downward bending of the upright surface 71 and better ensuring that the upright surface 71 remains in contact with the electrical contact area on the circuit board. This structure, by configuring the upper movable seat 121 and the lower movable seat 123 to achieve the horizontal bending and downward bending of the upright surface 71 respectively, can further reduce the possibility of material damage.

[0028] When the lifting drive 16 uses an electric push rod, the electric push rod moves at a relatively high speed and exerts a large force, which can easily cause damage when the material is lifted to the crimping head 12 by the positioning table 14. In this embodiment, the buffer structure is a tension spring 155, with both ends of the tension spring 155 connected to the base and the lifting seat 13, respectively. Thus, when the lifting drive 16 is activated, the tension spring 155 provides tension to the lifting seat 13, partially offsetting the thrust during the lifting process of the lifting seat 13, reducing the rising speed of the lifting seat 13 and the positioning table 14, and reducing the force when the material contacts the crimping head 12.

[0029] The buffer structure further includes a pad 151 and a swing arm 152. The pad 151 is disposed on the base, and the upper end of the swing arm 152 is hinged to the lifting seat 13. The upper end of the tension spring 155 is attached to the lower end of the swing arm 152, and the lower end is attached to the base. The lower end of the swing arm 152 is located above the pad 151. When the lifting seat 13 is driven to descend by the lifting drive 16, the lower end of the swing arm 152 abuts against the pad 151. The arrangement of the pad 151 and the swing arm 152 provides buffering when the linear drive drives the lifting seat 13 and the positioning platform 14 to descend. Specifically, the upper end of the tension spring 155 is connected to the lower end of the swing arm 152, and the lower end of the tension spring 155 is located above the pad 151. The tension spring 155 causes the lower end of the swing arm 152 to tend to move towards the pad 151. During the process of the lifting driver 16 driving the lifting seat 13 to descend, the tension spring 155 can pull the swing arm 152 to swing downward and hit the pad 151, thereby decelerating the lifting seat 13 and reducing the impact force on the lifting seat 13 during descent.

[0030] The semi-finished product edge-rolling device also includes an air supply mechanism. A first vent hole is provided on the top surface of the positioning platform 14, and this first vent hole is connected to the air supply mechanism via a pipe. The first vent hole on the top surface of the positioning platform 14 allows for the introduction of positive or negative pressure to facilitate the entry and exit of materials. Specifically, when the material is pushed onto the positioning platform 14 by the pusher head 23 of the feeding mechanism, the air supply mechanism introduces negative pressure through the pipe into the first vent hole to draw air in, stably adsorbing the material onto the positioning platform 14 and enabling the material to be quickly positioned on the platform. After the material has completed the edge-rolling process, the air supply mechanism can blow air through the first vent hole to lift the material from the positioning platform 14, helping the material to quickly leave the platform 14.

[0031] Furthermore, since the lifting seat 13 is equipped with a swing arm 152 and a tension spring 155, the swing arm 152 can exert an upward force on the lifting seat 13 when it contacts the pad 151 during the descent of the lifting drive 16. By setting the air blowing time of the first vent hole after the swing arm 152 contacts the pad 151, the problem of the material being stuck on the positioning table 14 by the tight pressure of the edge rolling head 12 can be prevented, thus preventing the material from being removed from the positioning table 14 by air blowing. This better ensures that the edge rolling device of the finished plate can operate continuously and stably.

[0032] To accelerate the material feeding speed, the feeding mechanism also includes a guide seat 24, which has a second air blowing hole 81 located above the positioning platform 14 and facing it. The air supply mechanism is connected to the second air blowing hole 81 via a pipe. Thus, when the pusher head 23 pushes the material near the positioning platform 14, the air supply mechanism supplies positive pressure to the second air blowing hole 81, enabling the material to be quickly transferred to the positioning platform 14 by blowing air. Furthermore, when the material needs to leave the positioning platform 14 and flow to another side, the timing of the air blowing through the first air blowing hole 82 and the second air blowing hole 81 can accelerate the material transfer speed. Specifically, after the first air blowing hole 82 blows the material up, the second air blowing hole 81 supplies positive pressure and blows out gas, which can quickly move the material to the other side, thus rapidly transferring the material downstream.

[0033] In this embodiment, to improve the service life of the swing arm 152, the buffer structure further includes a shaft 154 and a washer 153. The shaft 154 is detachably connected to the lower end of the swing arm 152, and the washer 153 is connected to the shaft 154, with the lower end of the washer 153 located below the swing arm 152. With the washer 153 and shaft 154 positioned below the swing arm 152, the washer 153 can absorb the impact force generated when colliding with the pad 151, replacing the swing arm 152. Furthermore, the shaft 154 connects the swing arm 152 and the washer 153. Since the structural strength of the shaft 154 is lower than that of the lower end of the swing arm 152, the shaft 154 also provides a safety guarantee for the swing arm 152. In the event of structural damage due to malfunction or long-term operation, the shaft 154 will fail before the swing arm 152. Replacing the shaft 154 allows for rapid repair and ensures production.

[0034] The lower end of the swing arm 152 has a first screw hole. The insert shaft 154 is a screw, which is threaded into the first screw hole. The tail of the screw protrudes from the first screw hole. The washer 153 is located between the head of the screw and the swing arm 152. The upper end of the tension spring 155 is hooked onto the tail of the screw. After the first screw hole is opened at the lower end of the swing arm 152, the screw can be easily attached to and detached from the lower end of the swing arm 152 using the insert shaft 154. The washer 153 can be clamped as needed, allowing it to rotate or not rotate. In this embodiment, the washer 153 is in a non-rotating state. This ensures a more even force distribution when the swing arm 152 contacts the pad 151.

[0035] The base is also provided with a second screw hole, and a mounting screw 156 is threaded into the second screw hole. The other end of the tension spring 155 is hung on the mounting screw 156. By configuring the mounting screw 156, the tension spring 155 can be easily connected.

[0036] The semi-finished product edge-rolling device also includes a feeding chute 3, which is located on the side of the positioning platform 14 away from the pusher head 23. The feeding chute 3 allows the material to automatically slide to other positions directly through it after edge-rolling and being blown out.
