Description

Technical Field

[0001] This utility model relates to the field of machining and manufacturing, and in particular to a device for integrally forming a steel door panel and a cover edge. Background Technology

[0002] With the increasing diversification of the entrance door industry, steel door manufacturing processes have undergone numerous optimizations and upgrades. The original steel door leaf cover seam production process was cumbersome and inefficient, significantly limiting steel door production volume. The original bending process used external force to bend metal materials into the required angles and shapes; this process had relatively low dimensional accuracy and stability, potentially leading to insufficient production efficiency during large-scale production.

[0003] The existing technology has the following main problems: 1) The original bending process uses external force to bend the metal material into the required angle and shape. This process has relatively low dimensional accuracy and stability, and may face insufficient production efficiency when mass production is carried out; 2) The existing mold equipment cannot achieve one-piece molding. This method has low dimensional accuracy, non-compact structure, poor aesthetics, is not suitable for mass production, and has low production efficiency and high cost; 3) The existing bending process requires manual operation and multiple steps for the cover plate. The mold equipment cannot be adjusted as needed, so it is difficult to adapt to complex structural requirements.

[0004] Therefore, it is urgent to analyze and understand the product, design a mold equipment to match it, and then combine it with some mechanical equipment to simplify the steps for employees to operate and improve production efficiency, while ensuring product quality, making certain optimizations in appearance, and designing a new device suitable for mass production to improve production efficiency and adapt to complex structural requirements. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a device for integrally forming a steel door panel and a cover edge.

[0006] This integrated molding device for steel door panel and edge covering includes a transition edge processing device and an edge covering processing device. The transition edge processing device includes an upper die component 1 and a lower die component 1. The edge covering processing device includes an upper die component 2, a lower die component 2, and a lower die component 3. The cutting edge of the upper die component 1 and the cutting edge of the lower die component 1 are matched in shape. The cutting edge of the upper die component 2 and the top cutting edge of the lower die component 2 are matched in shape. The lower die component 2 has a hammer pressing head at its bottom, and a reverse stepped sidewall is provided on one side of the hammer pressing head.

[0019] The present invention will be further described below with reference to embodiments. The description of the embodiments below is only for the purpose of helping to understand the present invention. It should be noted that, for those skilled in the art, several modifications can be made to the present invention without departing from the principle of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.

[0020] Example 1

[0021] As one example, such as Figure 1 As shown, this integrated molding device for steel door panel and edge covering includes a transition edge processing device and an edge covering processing device; both the transition edge processing device and the edge covering processing device have a bottom mold 4 fixed at their bottom; the bottoms of the lower mold component 1 3 and the lower mold component 3 7 are connected to the top of the bottom mold 4 by a mortise and tenon structure; the bottoms of the lower mold component 1 3 and the lower mold component 3 7 are both tenons of the same shape, and the top of the bottom mold 4 is a mortise of the same shape; the product processing is divided into transition edge processing and edge covering processing.

[0022] like Figure 2 As shown, the transition edge processing device includes an upper die component 1 and a lower die component 3; the cutting edges of the upper die component 1 and the lower die component 3 are shaped to match each other; the lower die component 3 is connected to the top of the bottom die 4 by a tenon and mortise structure; the upper die component 1 and the lower die component 3 are located on the same axis, and the cross-sectional shape of the cutting edges of the upper die component 1 and the lower die component 3 is a polygonal line.

[0023] During the transition edge processing stage, the door leaf component 2 is placed between the upper die component 1 and the lower die component 3. The upper die component 1 is pressed downward by an external mechanical device, so that it acts on the door leaf component 2, the lower die component 3 and the bottom die 4. The cutting edge of the upper die component 1 and the cutting edge of the lower die component 3 engage, so that the door leaf component 2 is pressed into a folded shape, and the transition edge between the cover edge and the door leaf panel is pressed into place.

[0024] Example 2

[0025] As another embodiment, this second embodiment proposes a more specific integrated molding device for steel door panel and cover edge based on the first embodiment:

[0026] like Figure 3 As shown, the edge-covering processing device includes an upper die component 2 5, a lower die component 2 6, and a lower die component 3 7. The cutting edges of the upper die component 2 5 and the top cutting edges of the lower die component 2 6 are identical in shape, and the cross-sectional shape of the cutting edges of the upper die component 2 5 and the top cutting edges of the lower die component 2 6 is V-shaped. The lower die component 2 6 has a hammer pressing head at its bottom, and one side of the hammer pressing head has a stepped sidewall. The lower die component 3 7 has a platform in the middle, and one side of the platform has a stepped sidewall. The hammer pressing head at the bottom of the lower die component 2 6 and the platform in the middle of the lower die component 3 7 are parallel. The hammer pressing head at the bottom of the lower die component 2 6 and the sidewall of the lower die component 3 7 are spaced apart to allow space for material overflow caused by the door panel component 2 during hammer pressing.

[0027] The anti-stepped sidewall and the stepped sidewall match in shape, forming a guide device between the anti-stepped sidewall of the lower die component 26 and the stepped sidewall of the lower die component 37, so that the lower die component 26 can slide vertically on the sidewall of the lower die component 37.

[0028] The bottom of the lower die component 3 7 is connected to the top of the bottom die 4 by a tenon and mortise structure; the upper die component 2 5, the lower die component 2 6, and the lower die component 3 7 are located on the same axis, and the side walls of the lower die component 2 6 and the lower die component 3 7 are secured with screws.

[0029] During the edge-covering process, the partially processed door leaf component 2 is transferred to the edge-covering processing device. The pressure of an external mechanical device presses the upper die component 2 5 downwards, so that it acts on the door leaf component 2 and the lower die component 2 6. The cutting edges of the upper die component 2 5 and the lower die component 2 6 mesh and bend into a V-shape on the door leaf component 2, so that the door leaf component 2 is roughly shaped and the approximate shape of the edge is formed.

[0030] In the final processing stage, one end of the door leaf component 2 is placed between the bottom hammer head of the lower mold component 2 6 and the middle table of the cutter lower mold component 3 7. A force is applied to the cutter upper mold component 2 5 so that it acts on the cutter lower mold component 2 6, the door leaf component 2, and the cutter lower mold component 3 7. The bottom hammer head of the cutter lower mold component 2 6 hammers onto the door leaf component 2, pressing the V-shaped edge into a double-layered cover, and finally pressing to obtain the desired product.

[0031] It should be noted that the parts in this embodiment that are the same as or similar to those in Embodiment 1 can be referred to each other, and will not be repeated in this application.

[0032] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
