Technical Field

[0001] This utility model relates to the field of riveting technology, specifically a device for quickly riveting metal clips. Background Technology

[0002] Products consisting of a metal cover and a bottom shell, such as Figure 9 Currently, the assembly method for such products involves using an arc-shaped structure for the buckle parts, with bending and riveting performed simultaneously. This method results in incomplete bending and loose riveting, leading to substandard product quality. Utility Model Content

[0003] This invention provides a device for quickly riveting metal buckles, which solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A device for quickly riveting metal buckles includes a mold frame mechanism, a bending mechanism, and a riveting mechanism;

[0006] The mold frame mechanism includes a base plate, a support column is provided in the middle of the base plate, a product positioning block is provided at the upper end of the support column, a guide rod is provided at the corner of the base plate, and a sliding plate is provided on the side of the guide rod near the base plate.

[0007] The bending mechanism includes sliders slidably connected to both sides of the slide plate, a transverse return spring between the sliders and the product positioning block, and a bending plate at the top of the sliders.

[0008] The riveting mechanism includes an upper mounting plate slidably connected to the guide rod on the side away from the base plate. A riveting block and a pre-pressing column are provided on the side of the upper mounting plate close to the base plate. A driving device for driving the upper mounting plate to move toward the base plate is provided on the side of the upper mounting plate away from the base plate. Inclined top blocks that cooperate with the slider are provided on both sides of the upper mounting plate.

[0009] As a preferred embodiment of this utility model, a longitudinal return spring is provided between the slide plate and the upper mounting plate, and the longitudinal return spring is sleeved on the outside of the guide rod.

[0010] As a preferred technical solution of this utility model, the two sides of the slide plate are provided with limiting pins to limit the maximum distance between the two sliders.

[0011] As a preferred embodiment of this utility model, guide sleeves are provided at the four corners of the upper mounting plate, and the guide sleeves are slidably connected to the guide rods.

[0012] As a preferred embodiment of this utility model, the pre-compression column is slidably connected to the upper mounting plate, and a pre-compression spring that cooperates with the upper mounting plate is sleeved on the outer side of the pre-compression column.

[0013] As a preferred embodiment of this utility model, a product is placed on the product positioning block.

[0014] As a preferred embodiment of this utility model, a recess is provided below the inclined top block, and a guide slope is provided at the lower end of the inclined top block. A protrusion that cooperates with the recess is provided on the side of the slider away from the center of the slide plate.

[0015] The present invention has the following advantages:

[0016] This utility model relates to a device for quickly riveting metal buckles. Utilizing the inclined groove of the inclined top block, the bending mechanism has space to reset and retract. With no obstruction above the metal buckle, the riveting mechanism can continue to move downwards, thus tightening the metal buckle. During the reset process, the bending mechanism moves back to its limit position. Because the riveting forming surface is lower than the bending surface and a certain distance is maintained, the bending plate will not touch the product, thus avoiding scratches and ensuring product quality meets standards. Only one direction of external power is needed to separate the bending and riveting steps, allowing them to operate sequentially. This results in stable and reliable finished product quality and significantly improved production efficiency. Attached Figure Description

Limiting pins 6 are provided on both sides of the slide plate 16 to limit the maximum distance between the two sliders 2.

[0034] In one embodiment, guide sleeves 13 are provided at the four corners of the upper mounting plate 11, and the guide sleeves 13 are slidably connected to the guide rods 12. The preload column 9 is slidably connected to the upper mounting plate 11, and a preload spring 10 that cooperates with the upper mounting plate 11 is sleeved on the outer side of the preload column 9.

[0035] Please see Figure 9 In one embodiment, a product 18 is placed on the product positioning block 5. The product 18 consists of a metal cover 20 and a bottom shell 19.

[0037] Implementation process of this embodiment:

[0038] 1. Please refer to Figure 4 The product 18 is pre-assembled and placed into the cavity of the product positioning block 5. The riveting mechanism is pressed down by the drive device 17, the pre-pressing column 9 presses the product 18, the inclined surface at the lower end of the inclined top block 7 contacts the inclined surface at the upper part of the slider 2, and the bending mechanism moves towards the middle.

[0039] 2. Please refer to Figure 5 In the bending mechanism, the bending plate 15 bends the metal buckle into a horizontal state, and at the same time, the lower end of the recess of the inclined top block 7 contacts the top of the protrusion of the slider 2, and the bending mechanism reaches the limit position.

The upper space of the metal buckle is unobstructed, allowing the riveting mechanism to continue moving downwards, thereby tightening the metal buckle. During the device's reset process, the bending mechanism moves back to its limit position. Because the riveting forming surface is lower than the bending surface and a certain distance is maintained, the bending plate 15 will not touch the product 18, thus avoiding scratches and ensuring the product 18 meets quality standards. Only one direction of external power is needed to separate the bending and riveting steps, allowing them to operate sequentially. This results in stable and reliable finished product quality and significantly improved production efficiency.
