Description

Technical Field

[0001] The utility model specifically relates to an aluminum profile extrusion die capable of preventing cantilever springback. Background Art

[0002] Rail guides and large-notch cantilever large aluminum profiles are widely used in the construction field. They have the characteristics of light weight, high strength, good corrosion resistance, good thermal conductivity and good processing performance. In construction, they are commonly used in the frames of aluminum alloy doors and windows, curtain walls, the structures and roof panels of aluminum alloy roofs, the exterior and interior decorations of aluminum alloy wall panels, and aluminum alloy staircase handrails, etc. For example, in aluminum alloy doors and windows, the large-notch aluminum profiles of the rail guides can provide stable structural support while ensuring the beauty and airtightness of the doors and windows. In curtain wall design, its unique notch design can enhance the stability and decorative effect of the curtain wall;

[0003] However, in the application field of aluminum profile extrusion dies, when the above-mentioned aluminum profiles are produced, the stress at the cantilever part is relatively concentrated, the flow velocity of the aluminum flow is unstable, and the cantilever springback phenomenon often occurs, seriously affecting the finished product quality of the aluminum profiles.

[0004] Therefore, it is necessary to invent an aluminum profile extrusion die capable of preventing cantilever springback to solve the above problems. Content of the Utility Model

[0005] (I) Purpose of the Utility Model

[0006] To solve the technical problems existing in the background art, the utility model proposes an aluminum profile extrusion die capable of preventing cantilever springback. By setting an inclined surface in the feed hole, while guiding the flow direction of the aluminum flow, the stress concentration at the cantilever of the aluminum profile is avoided. The setting of the convex column and the pin hole can effectively support the cantilever of the aluminum profile, thereby avoiding the cantilever springback caused by stress concentration and insufficient stability at the cantilever. Further, the setting of the flow guiding plate enables the aluminum flow to have a long-distance flow buffer zone, so that it can enter the welding chamber smoothly and evenly, reducing the cantilever springback phenomenon caused by uneven aluminum flow. Since the welding chamber has the same shape as the feed hole and a chamfer is provided at the bottom periphery, the aluminum flow can still remain stable after flowing in smoothly, and then flow into the cavity evenly to complete the production, thereby effectively preventing the aluminum profile from undergoing cantilever springback, improving the finished product quality of the aluminum profile, and reducing the rejection rate.

On one side corresponding to the two horizontal sides of the inlet hole, inclined surfaces are milled and sunk towards the center direction of the deflector. A pin hole is also provided at the bottom of the deflector.

[0010] A template is arranged at the bottom of the deflector. At the top of the template, there is a welding chamber with the same shape as the inlet hole and communicating with the inlet hole. A cavity communicating with the welding chamber is also provided inside the template. At the top of the template, there is also a convex post adapted to the pin hole.

[0011] Preferably, a discharge hole communicating with the cavity is provided at the bottom of the template.

[0012] Preferably, the cavity and the discharge hole are also in a C shape, which is used for the hot extrusion forming of aluminum profiles and the discharge of the formed aluminum profiles.

[0013] Preferably, the deflector and the template are tightly fitted with each other to form a mold body, and the assembly method is set as a reverse rabbet assembly type.

[0014] Preferably, the vertical height difference of the inclined surface is set to 1 mm.

[0015] Preferably, the bottom periphery of the welding chamber is chamfered, and the depth of the welding chamber is not greater than mm.

[0016] Compared with the prior art, the beneficial effects of the above technical solutions of the present utility model are as follows:

[0017] 1. By arranging inclined surfaces in the inlet hole of the deflector, the present utility model can guide the flow direction of the aluminum flow, enabling the aluminum flow to flow smoothly and evenly into the welding chamber, avoiding stress concentration at the cantilever of the aluminum profile, reducing the possibility of cantilever springback of the aluminum profile, and when assembling the deflector and the template, the setting of the convex post and the pin hole can effectively support the cantilever of the aluminum profile, further improving the strength and stability of the cantilever, avoiding cantilever springback caused by stress concentration at the cantilever, and reducing the occurrence of cantilever springback again;

[0018] 2. By arranging a deflector with a C-shaped inlet hole, the present utility model provides a longer flow buffer zone for the aluminum flow, which can control the flow of the aluminum flow, enabling it to enter the welding chamber smoothly and evenly, reducing the phenomenon of cantilever springback caused by uneven aluminum flow. Since the welding chamber has the same shape as the inlet hole, the aluminum flow can flow smoothly into the interior of the welding chamber, and the bottom periphery of the welding chamber is chamfered, so that the aluminum flow can still maintain a smooth flow in the welding chamber, and then flow smoothly and evenly into the cavity to complete production, thereby effectively preventing the aluminum profile from undergoing cantilever springback, improving the finished product quality of the aluminum profile, and reducing the scrap rate.

[0027] To enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the accompanying drawings.

[0028] The present utility model provides an aluminum profile extrusion die capable of preventing cantilever springback as shown in Figures 1-4 Figure 35, including a deflector 1, a feed hole 11 is opened at the top of the deflector 1, and the feed hole 11 is set in a C shape. On the side surfaces corresponding to the two horizontal sides of the feed hole 11, inclined surfaces 12 are milled and sunken towards the center direction of the deflector 1. A pin hole 13 is also opened at the bottom of the deflector 1;

[0029] A template 2 is arranged at the bottom of the deflector 1. A welding chamber 21 having the same shape as the feed hole 11 and communicating with the feed hole 11 is arranged at the top of the template 2. A cavity 22 communicating with the welding chamber 21 is also opened inside the template 2. A convex column 23 adapted to the pin hole 13 is arranged at the top of the template 2;

[0030] A discharge hole 24 communicating with the cavity 22 is opened at the bottom of the template 2. The cavity 22 and the discharge hole 24 are also set in a C shape for the hot extrusion forming of the aluminum profile and the discharge of the formed aluminum profile.

[0031] The specific implementation method is as follows: When the present utility model is in use, the flow guiding plate 1 and the template 2 are tightly assembled with each other in a way of assembling with a return stop port to form a die body, which enhances the stability after the assembly of the flow guiding plate 1 and the template 2, ensures the integrity of the die body, and the flow guiding plate 1 is provided with a flow guiding plate 1 with a C-shaped feeding hole 11, so that before the aluminum flow reaches the welding chamber 21 of the template 2, there can be a flow buffering zone with a relatively long distance, controlling the flow of the aluminum flow, so that the aluminum flow can smoothly and evenly enter the welding chamber 21, reducing the cantilever spring deformation phenomenon caused by uneven aluminum flow;

[0032] And an inclined surface 12 is arranged in the feeding hole 11, which can guide the flowing direction of the aluminum flow, so that when the aluminum flow transitions from the feeding hole 11 to the welding chamber 21, it has strong fluidity, and further reduces the occurrence of cantilever spring deformation;

[0033] At the same time, the vertical height difference of the inclined surface 12 is set to 1 mm, avoiding stress concentration at the cantilever of the aluminum profile, optimizing the force at this place, and when the flow guiding plate 1 and the template 2 are assembled, the convex column 23 will also be inserted into the pin hole 13 to effectively support the cantilever of the aluminum profile, further improving the strength and stability of the cantilever, and avoiding the cantilever spring deformation caused by stress concentration at the cantilever;

[0034] When the aluminum flow reaches the inside of the welding chamber 21, since the welding chamber 21 has the same shape as the feeding hole 11, that is, both are C-shaped, the aluminum flow can smoothly flow into the inside of the welding chamber 21, and the bottom periphery of the welding chamber 21 is chamfered, so that the aluminum flow can still remain stable in the welding chamber 21, and then smoothly and evenly flow into the cavity 22 to complete the production. And the depth of the welding chamber 21 is not greater than 10 mm, which ensures the assembly accuracy and working performance of the template 2;

[0035] Finally, after the aluminum flow enters the cavity 22, the finished aluminum profile product will be produced and discharged through the discharge hole 24. This method can effectively prevent the cantilever spring deformation of the aluminum profile, improve the quality of the finished product, reduce the rejection rate, and at the same time enhance the integrity and stability of the die body, and extend the service life of the die;

[0036] This specific implementation method specifically solves the problem in the prior art that in the application field of aluminum profile extrusion dies, when the above-mentioned aluminum profiles are produced, the force at the cantilever part is relatively concentrated, the flow rate of the aluminum flow is unstable, and the cantilever spring deformation phenomenon often occurs, seriously affecting the quality of the finished aluminum profile.

[0037] Only some exemplary embodiments of the present utility model are described by way of illustration. Undoubtedly, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
