Description

Technical Field

[0001] The invention relates to a riveting structure, in particular to an in-mold automatic riveting structure. Background Art

[0002] The Netcom shielding frame has four-side bending structure. To ensure the stability of the product structure, usually two adjacent sides (folded edge 100 and folded edge 200) will be buckled with each other by means of connecting angle 300 jacks. After buckling, the connecting angle is bent, so that the product becomes a stable whole and is not easy to deform (such as Figure 1 As shown). In actual production, this type of product is usually produced by a continuous die plus a single engineering riveting die. Because the continuous die production requires that there are material points on the product that are connected to the material belt, so as to ensure that the product will float up and down and move forward with the material belt, so as to achieve the purpose of completing the corresponding processing of the product at different workstations. However, due to the shielding signal of the Netcom shielding frame, the material connection points can only be made on the two opposite bending edges. When these two bending edges are to be bent, the material points must be cut off first. The product cannot be processed further because there is no material point. Only the four sides of the product can be bent on the continuous die, and the connecting corner riveting cannot be performed. Only a set of riveting dies can be added separately to perform the connecting corner riveting.

[0003] Therefore, the disadvantages and shortcomings of the prior art are as follows: 1. A riveting mold needs to be added, which increases the mold opening cost. 2. The riveting mold requires additional manual operation, which increases the labor cost. 3. The riveting mold is a single-process mold, and the production speed is very low, which affects the production efficiency. Summary of the invention

[0004] In order to solve the problems of the prior art, the present invention provides an in-mold automatic riveting structure with simple process flow, labor saving, high production efficiency and high product quality.

[0005] The specific technical scheme is as follows: an in-mold automatic riveting structure, including a movable feeding device, a movable fixing device, a product positioning device and a riveting part, the movable feeding device includes a bottom plate and a side plate, the side plates are arranged on both sides of the bottom plate, the movable fixing device is arranged on the side plate, the product positioning device is arranged on the bottom plate, the riveting part is arranged in the side plate, there are multiple riveting parts, and the multiple riveting parts are arranged in parallel and at intervals. The above technical scheme solves the problem of synchronization between the product and the entire material strip due to the lack of a material point after the four sides of the product are bent, including simultaneous floating and advancing one station at the same time during feeding. The product has no material point, and can also stop at a predetermined position when it arrives at the riveting station, without moving forward or delaying. The product will not shake during riveting to avoid affecting the riveting effect. During riveting, the bending edge is clamped by the movable fixing device to ensure that other positions will not be deformed due to force, and the product will not be deformed due to riveting force.

[0006] The following are the subsidiary technical solutions of the present invention.

[0007] As a preferred solution, the product positioning device includes a positioning component, and the positioning component has a positioning groove. Through the above technical solution, the bent edge on one side of the product can be stuck in the positioning groove.

[0008] As a preferred solution, the positioning assembly includes a first positioning block and a second positioning block. The first and second positioning blocks are arranged opposite to each other, and the positioning groove is arranged between the first positioning block and the second positioning block. Through the above technical solution, the product can be prevented from shaking back and forth.

[0009] As a preferred solution, there are multiple groups of positioning components, and the multiple groups of positioning components are arranged at intervals. Through the above technical solution, the positioning of the product can be made more stable.

[0010] As a preferred solution, the side plate is provided with a slide groove. Through the above technical solution, the product can slide in the slide groove, which is convenient for product movement.

[0011] As a preferred solution, there are two side panels, which are arranged opposite to each other. Through the above technical solution, the movement of the product can be limited, so that the product can move stably.

[0012] As a preferred solution, the side plate is provided with a groove, and the riveting parts and the movable fixing device are arranged in the groove. Through the above technical solution, the movable fixing device can clamp the bent edge.

[0013] As a preferred solution, there are four riveting parts, and the four riveting parts are arranged parallel to each other. Through the above technical solution, the four corners of the product can be riveted.

[0014] The technical effects of the present invention are as follows: 1. It saves mold opening costs and greatly reduces mold opening costs. 2. It saves operators for riveting molds and reduces labor costs. 3. Because continuous mold production is used, production efficiency is greatly improved, and product production capacity is greatly improved. 4.
