Description

Technical Field

[0001] This utility model relates to the field of furniture slide rail manufacturing, specifically a continuous production line for the stamping and riveting of the middle rail of a slide rail. Background Technology

[0002] Drawer slides are commonly used connecting components in furniture, primarily used to open and close drawers on cabinets. To extend the sliding stroke of the slides and open larger drawers, Chinese patent documents CN118714793A and CN1939188A disclose a three-section drawer slide. Chinese patent document CN107413942A discloses a continuous stamping production line for drawer slides, which uses a series of stamping processes—including punching, bending, locking, and hook-punching dies—to form the slides. While these production lines improve the automation of drawer slide processing to some extent, they still have two significant technical drawbacks. First, the punching, bending, locking, and hook-punching dies are all located within the same stamping device. Since the dimensions and thicknesses of the parts to be processed vary, the required stamping pressure also differs. This production line cannot adjust the pressure according to actual needs, making it prone to over-stamping when processing different parts, leading to deformation or even damage to the processed parts. Secondly, when the stamping device performs continuous stamping processing, it will cause the mold to vibrate strongly. This vibration will cause the continuously arranged punching mold, tail-breaking mold, locking mold, and punch hook mold to resonate synchronously, and the forming parts installed in the above molds will loosen or even fall off under the resonance effect, which will seriously affect the normal processing of the slide rail. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a continuous production line for stamping and riveting of slide rails and middle rails that is highly stable and can be continuously processed.

[0004] This utility model provides a continuous production line for stamping and riveting of a slide rail, including a feeding device and a stamping device arranged in sequence. The stamping device includes a first stamping component and a second stamping component arranged along the slide rail conveying direction. A flipping conveyor is provided between the first stamping component and the second stamping component. A riveting device is provided on the outside of the second stamping component along the slide rail conveying direction. A first robot is provided between the flipping conveyor and the second stamping component. A second robot is provided between the second stamping component and the riveting device.

[0006] By optimizing the above structure, the first stamping assembly includes a first stamping machine and a first stamping die disposed on the first stamping machine and corresponding to the position of the outlet end of the feeding device.

[0007] By optimizing the above structure, the second stamping assembly includes a second stamping machine and a second stamping die disposed on the second stamping machine and corresponding to the exit end position of the first stamping assembly.

[0008] By optimizing the above structure, the flipping conveyor includes a feeding device, a flipping device, and a material feeding device, all of which are installed on the flipping conveyor frame. The feeding device is positioned opposite to the outlet end of the first stamping component, the flipping device is positioned opposite to the feeding device, and the material feeding device is located on the opposite side of the flipping device and the feeding device.

[0009] By further improving the above structure, the feeding device includes a feeding conveyor belt located on the feeding frame and corresponding to the outlet end of the first stamping component, and a transverse feeding push cylinder located on the side of the feeding conveyor belt opposite to the outlet end of the first stamping component.

[0010] By further improving the above structure, the flipping device includes a flipping seat on the flipping frame, a flipping motor on the flipping seat, a flipping arm driven by the flipping motor and corresponding to the position of the feeding device, and a clamping cylinder on the flipping seat that moves the flipping arm relative to the slide rail along its length.

[0013] The beneficial effects of this utility model's continuous production line for stamping and riveting the middle rail of a slide rail are as follows:

[0014] 1. This utility model employs a combination structure of intermittent conveying by a first robotic arm and a second robotic arm, along with a slide rail flipping device. Firstly, intermittent conveying prevents insufficient or excessive pressure during processing of different parts due to varying stamping pressure requirements, thus avoiding deformation or damage after stamping. Secondly, the flipping device ensures a tight connection between the slide rail's processing surface and the mold during different stamping processes, and prevents deformation of the hollow portion of the slide rail after forming during stamping.

[0015] 2. In this invention, the slide rail is flipped and conveyed after being output from the first stamping assembly by the cooperation of a transverse feeding push cylinder, a flipping arm driven by a flipping motor and a clamping cylinder, and a material feeding drive cylinder, which greatly reduces the need for manual operation. At the same time, the automated flipping structure can also improve the stability and reliability of slide rail processing, increase processing efficiency, and reduce the generation of defective products.
