Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to an elastic support plate lower mold device for riveting. Background Technology

[0002] Currently, during riveting, workers manually support the product to ensure that the rivet does not touch the lower die or just barely touches it before riveting (because if the lower die supports the rivet and product before riveting, the rivet will fall out before it is riveted). However, manually placing the product by feel can easily cause it to tilt. Due to uneven force, this leads to defects such as riveting marks, dents, or product deformation, increasing rework costs and even scrapping the product. Furthermore, this method is unsuitable for mass production (e.g., ...). Figure 1 (As shown). Utility Model Content

[0003] The purpose of this invention is to provide an elastic support plate lower mold device for riveting, which adopts a guide post type sliding elastic structure. Through the contact between the support plate and the product throughout the riveting process, it ensures stable processing of the product, thereby improving product quality, reducing product defect rate, reducing production costs, and improving production efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an elastic support plate lower mold device for riveting, comprising an upper mold fixed to a riveting machine, and further comprising a support plate, an elastic guide post assembly and a lower mold, wherein the support plate is movably disposed above the lower mold, and the elastic guide post assembly is installed in corresponding holes in the support plate and the lower mold.

[0005] Furthermore, the elastic guide post assembly includes a movable ejector pin, an ejector pin base, a spring, a fastening screw, and a sliding guide post. The sliding guide post is installed in the sliding guide post hole of the lower mold. The spring is sleeved on the ejector pin base. The movable ejector pin is installed in the ejector pin base. The ejector pin base is fixed to the movable ejector pin hole of the lower mold by the fastening screw.

[0006] Furthermore, the spring is a 65MN spring with a wire diameter of 1.0mm, an outer diameter of 4.0mm, and a length of 10mm.

[0007] Furthermore, both sides of the lower mold have 90-degree abutment portions.

[0008] Furthermore, the elastic guide post assembly adopts an up-and-down sliding elastic floating structure.

[0009] Furthermore, the head of the movable pin is cone-shaped.

[0010] Furthermore, the tray is L-shaped, with sliding guide holes on both sides, and there are at least two sliding guide holes.

[0011] This invention can reduce production costs and enhance industry competitiveness. The process is simple and easy to operate, improves work efficiency, and solves the problem that when products are riveted, people place them by feel, causing them to tilt and resulting in uneven force, which leads to defects such as riveting marks, pressure marks, or product deformation.

Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0025] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0027] Please see Figures 1 to 11 A flexible support plate and lower die device for riveting includes an upper die 1 fixed to a riveting machine 14, a support plate 2, a flexible guide post assembly 3, and a lower die 9. The support plate 2 is movably disposed above the lower die 9, and the flexible guide post assembly 3 is installed in corresponding holes in the support plate 2 and the lower die 9. The flexible guide post assembly 3 adopts an up-and-down sliding elastic floating design, ensuring stable processing of the product through contact between the support plate 2 and the product throughout the riveting process. The support plate 2 supports the product, and the riveting machine 14 contacts the product through the upper die 1. As the upper die 1 presses downward, the riveting process is completed through the sliding of the flexible guide post assembly 3.

[0028] like Figure 3 As shown, the elastic guide post assembly 3 includes a movable ejector pin 4, an ejector pin base 5, a spring 6, a fastening screw 7, and a sliding guide post 8. The sliding guide post 8 is installed in the sliding guide post hole 10 of the lower mold 9. The ejector pin base 5 is fitted with the spring 6. The movable ejector pin 4 is installed in the ejector pin base 5. The ejector pin base 5 is fixed to the movable ejector pin hole 11 of the lower mold 9 by the fastening screw 7.

[0029] like Figure 3 As shown, spring 6 is a 65MN spring with a wire diameter of 1.0mm, an outer diameter of 4.0mm, and a length of 10mm. The elastic guide post assembly 3 adopts a sliding, elastic floating structure. The head of the movable ejector pin 4 is conical, facilitating connection to the center hole of the riveting stud and serving as a guide and positioning element, achieving the automatic guiding and positioning requirements for riveting. This solves the problem that the height of the riveting stud in the product design is close to the plate thickness, making it impossible to complete the processing through self-positioning of the riveting stud.

[0030] like Figure 4As shown, both sides of the lower mold 9 have 90-degree abutment parts 12.

[0031] like Figure 3 As shown, the tray 2 is L-shaped, and sliding guide post holes 10 are provided on both sides. There are at least two sliding guide post holes 10.

[0032] Working principle: The pallet 2 holds the product, and the riveting machine 14 contacts the product through the upper mold 1. As the upper mold 1 presses downward, the riveting process is completed by the sliding of the guide post.

[0033] Riveting process:

[0034] a. First, place the product into the lower mold 9, and position the product using the 90-degree edge of the lower mold 9. Specifically, as follows: Figure 4 , Figure 5 As shown.

[0035] b. Insert the countersunk rivet 13 into the corresponding hole in the product, as shown below. Figure 6 As shown.

[0036] c. Start the equipment by pressing the foot switch. The upper mold 1 slowly moves downwards. As the bottom surface of the upper mold 1 contacts the rivet 13, it continues to move downwards. The product presses against the tray 2, squeezing the elastic guide post downwards. At this moment, the sliding guide post 8 contacts the rivet 13. As the upper mold 1 continues to exert force, pushing the product and tray 2 downwards, the lower end of the rivet 13 is squeezed and deformed. When the tray 2 is fully pressed against the lower mold 9, the upper surface of the sliding guide post 8 is flush with the upper surface of the tray 2. At this point, the riveting process of the rivet 13 riveting the product is completed. (Details follow...) Figure 7 As shown

[0037] d. Then release the foot switch. The upper mold 1 of the machine slowly rises. Under the upward force of the spring 6 inside the elastic guide post assembly 3, the product is pushed upward and removed. This completes the riveting process for one product. (Details follow...) Figure 8 As shown.

[0038] The elastic support plate lower mold device of this utility model for riveting has an upper mold installed on the riveting machine 14. This lower mold device can be used to rivet products, whether they are left-swinging products 15 or right-swinging products 16.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
